(1) as shown in fig. 5, 6, 7, 9, in the normal pressure drainage mode:

A. during primary drainage, firstly, thecontroller 14 regulates and controls the working state of the drainage regulating assembly to promote thedrainage tube 18 to alternately and circularly output and suck fluid, so that the fluid in thedrainage tube 18 flows backwards, when theweighing sensor 16 senses weight change, it is indicated that partial accumulated fluid enters thedrainage bag 19, then thecontroller 14 regulates the middle movablepressing block 10 and the lowermovable pressing block 7 to the initial end of the stroke, and regulates the position of the upper movablepressing block 11 to keep thedrainage tube 18 in a conducting state, at the moment, primary drainage is started, and normal pressure drainage can be normally carried out by means of a siphon effect; in each drainage thereafter, thecontroller 14 adjusts the extrusion degree of the uppermovable pressing block 11 to thedrainage tube 18 according to the preset initial time of each drainage, so that thedrainage tube 18 is in a conduction state, namely, the timed drainage is realized;

B. in the drainage process, thecontroller 14 adjusts the extrusion degree of the upper movablepressing block 11 on thedrainage tube 18 according to the real-time drainage speed, so that the effusion speed in thedrainage tube 18 is increased or reduced, and finally the real-time drainage speed is approximately equal to the preset drainage speed, namely, the constant-speed drainage is realized;

C. in the drainage process, thecontroller 14 calculates the single real-time drainage amount from the initial drainage to the current drainage in real time, when the single real-time drainage amount reaches the preset single drainage amount, thecontroller 14 adjusts the extrusion degree of the upper movablepressing block 11 on thedrainage tube 18, so that the upper movablepressing block 11 extrudes thedrainage tube 18 to a blocking state, and the quantitative drainage is realized when the drainage is finished;

(2) as shown in fig. 5, 6, 9, in the negative pressure drainage mode:

A. according to the preset drainage starting time, thecontroller 14 regulates and controls the working state of the drainage regulating component, so that thedrainage tube 18 is promoted to alternately and circularly output and suck the fluid, and the fluid in thedrainage tube 18 flows backwards, namely the timing drainage is realized;

B. in the drainage process, thecontroller 14 adjusts the working state of the drainage adjusting assembly according to the real-time drainage speed, that is, adjusts the operating state of fluid output and fluid suction, and finally makes the real-time drainage speed and the preset drainage speed tend to be equal, that is, constant-speed drainage is realized, wherein the operating state of the fluid output and the fluid suction comprises the start-stop, duration and working frequency of the fluid output and the fluid suction;

C. in the drainage process, thecontroller 14 calculates the single real-time drainage amount from the initial point of the drainage to the current point in real time, when the single real-time drainage amount reaches the preset single drainage amount, thecontroller 14 adjusts the lower movablepressing block 7 to the stroke end, adjusts the upper movablepressing block 11 and the middle movablepressing block 10 to the respective stroke initial ends, and at the moment, the drainage is finished and thedrainage tube 18 is extruded by the lower movablepressing block 7 to keep a cut-off state, so that the quantitative drainage is realized;

in the negative pressure drainage mode, after drainage is finished, thecontroller 14 adjusts the lower movablepressing block 7 to the stroke end, and adjusts the upper movablepressing block 11 and the middle movablepressing block 10 to the respective stroke starting ends, the technical characteristics are that when the negative pressure drainage is suspended or finished, thedrainage tube 18 is extruded to the blocking state by the lower movablepressing block 7, so that effusion backflow in thedrainage tube 18 is avoided, thedrainage tube 18 is not extruded by the upper movablepressing block 11 and the middle movablepressing block 10, so that thedrainage tube 18 in the tube placing gap can be automatically restored to the original state, namely, the cylindrical shape, the long-term flattening state is avoided, the elasticity is greatly reduced, and the stable proceeding of the subsequent negative pressure drainage is ensured.

Referring to fig. 5, 6 and 9, when the multipurpose clinical drainage device is used clinically, in the negative pressure drainage process, the drainage adjusting assembly is controlled by thecontroller 14 to enable the uppermovable pressing block 11, the middle movablepressing block 10 and the lowermovable pressing block 7 to perform corresponding squeezing action on thedrainage tube 18 according to a specific rule, so that negative pressure drainage is realized and the negative pressure drainage state can be controlled; in the negative pressure drainage process, the structure that fixedbriquetting 8, last activity briquetting 11, well activity briquetting 10, lower activity briquetting 7 and put thedrainage tube 18 in the pipe clearance and constitute can be regarded as a displacement pump, and theory of operation is very similar with the diaphragm pump, and based on this, the drainage adjusting part can realize the negative pressure drainage and can carry out corresponding control to the negative pressure drainage state undercontroller 14's regulation and control, and specific theory of operation is as follows:

outputting the fluid:

as shown in fig. 5, before negative pressure drainage is performed, the upper movablepressing block 11, the middle movablepressing block 10 and the lower movablepressing block 7 are all located at the starting ends of the strokes of the respective movable strokes; when thecontroller 14 adjusts the upper movablepressing block 11 to the stroke end and keeps the lower movablepressing block 7 at the stroke beginning end, the upper end of thedrainage tube 18 in the tube placing gap is blocked, but the lower end of the drainage tube is communicated with thedrainage bag 19, when the middle movablepressing block 10 moves from the stroke beginning end to the stroke end, thedrainage tube 18 is extruded by the middle movablepressing block 10, the volume of the drainage tube is changed, and the accumulated liquid in the drainage tube flows towards the direction of thedrainage bag 19, so that the fluid output is realized;

fluid intake:

as shown in fig. 6, after the drainage regulating assembly causes thedrainage tube 18 to complete one-time fluid output, the upper movablepressing block 11 and the middle movablepressing block 10 are located at the stroke end of the respective movable stroke, and the lower movablepressing block 7 is located at the stroke beginning end of the movable stroke; when thecontroller 14 adjusts the lower movablepressing block 7 to the stroke end and the upper movablepressing block 11 to the stroke beginning end, the lower end of thedrainage tube 18 in the tube placing gap is blocked, but the upper end is communicated with the human body, when the middle movablepressing block 10 moves from the stroke end to the stroke beginning end, the flatteneddrainage tube 18 can gradually restore to a cylindrical shape by the elasticity of thedrainage tube 18, the front end of thedrainage tube 18 generates negative pressure along with the increase of the volume, and the effusion in the human body is sucked into thedrainage tube 18, so that the fluid suction is realized;

the realization of negative pressure drainage:

when the drainage regulating assembly prompts thedrainage tube 18 to alternately carry out fluid output and fluid suction, the fluid in thedrainage tube 18 can be ensured to always flow backwards, namely, the negative pressure drainage is realized;

adjusting the negative pressure drainage state:

when thecontroller 14 enables the drainage adjusting component to work in the manner, the negative pressure drainage is realized; when the drainage adjusting assembly stops working and thedrainage tube 18 is extruded to a blocking state by the lower movablepressing block 7, the negative pressure drainage is suspended or ended; when the operating frequency of fluid output and fluid suction is increased and the duration of the fluid output and the fluid suction is shortened, the drainage speed can be increased, and otherwise, the drainage speed is reduced.

Referring to fig. 8 and 9, in the above-mentioned multipurpose clinical drainage device, the weight-measuring suspension support assembly 4 mainly has two functions, on one hand, the weight-measuring suspension support assembly 4 provides a stable support for the drainage bag 19, so that the drainage bag 19 is in a suspension shape and has a basic function of containing drainage effusion during drainage, and on the other hand, during drainage, the weight sensor 16 in the weight-measuring suspension support assembly 4 can output a weight signal reflecting a change state of the effusion weight in the drainage bag 19, so as to provide basic data for data processing of the controller 14, and at the same time, the weight-measuring suspension support assembly 4 can also adjust the height of the drainage bag 19 within a certain range, so that after the drainage bag 19, the drainage tube 18 and the multipurpose clinical drainage device are combined, the part of the drainage tube 18 between the drainage groove 5 and the drainage bag 19 can be adjusted to a natural extension shape; in terms of the prior art, the weight-measuring suspension support assembly 4 can be obtained by slightly improving the structure of the existing electronic scale, and the specific structure has various implementation modes; however, in order to make the weighing suspension support assembly 4 more compact and more stable under the condition that the weighing suspension support assembly 4 meets the above requirements, the weighing suspension support assembly 4 is preferably implemented by adopting the following structure:

as shown in fig. 8 and 10, the weight-measuringsuspension assembly 4 includes a slidingsleeve 21, a weighingrod 22, aload cell 16 and asuspension portion 3; the slidingsleeve 21 is fixed on the placingplate 6, an inner cavity with an open lower end and a blind upper end is arranged in the slidingsleeve 21, the middle upper part of the weighingrod 22 is positioned in the slidingsleeve 21 and the weighingrod 22 can only slide up and down relatively, and the weighingsensor 16 is fixed in the slidingsleeve 21 and provides upward support for the weighingrod 22; the upper end of thesuspension part 3 is connected with the lower end of the weighingrod 22 in an inserting way, and alocking mechanism 20 for locking the relative positions of the suspension part and the weighing rod is arranged between the suspension part and the weighing rod; after thedrainage bag 19 is fixedly connected with the hangingpart 3, the weighingsensor 16 can pick up the weight change state of the accumulated liquid in thedrainage bag 19 and output a corresponding weight signal;

in addition, generally speaking, most of thedrainage bags 19 used in clinical practice at present are provided with a hanging ring at the top for convenient hanging, so that the lower end of the hangingpart 3 can be provided with ahook 23 for matching with the hanging ring of thedrainage bag 19, and in order to prevent thedrainage bag 19 and the hangingpart 3 from relatively rotating, thehook 23 can be made by bending a lath-shaped material; meanwhile, the lower end of the hangingpart 3 can also be provided with a clamping mechanism which can clamp and fix the upper end of thedrainage bag 19;

in the structure of the weight-countingsuspension support assembly 4, thesuspension part 3 cannot rotate relative to theplacing plate 6, so that stable support can be provided for thedrainage bag 19, and the phenomenon that the weight counting is not accurate due to the rotation or shaking of thedrainage bag 19 in the drainage process is avoided; the hangingpart 3 and the weighingrod 22 can transmit the weight change of the effusion in thedrainage bag 19 to the weighingsensor 16; the hangingpart 3 can be adjusted in position in the vertical direction so as to adjust the height of thedrainage bag 19; the structure meets the basic function requirement of the weight-measuring typesuspension support assembly 4, and has the advantages of simple structure, accurate measurement, small size, compactness and easy implementation.

Referring to fig. 6, when the multi-purpose clinical drainage device is used clinically, in the negative pressure drainage process, thedrainage tube 18 deforms to provide necessary pressure for the negative pressure drainage, generally speaking, thedrainage tube 18 used clinically at present has better elasticity, and in the initial stage of the negative pressure drainage, the elasticity of thedrainage tube 18 is optimal to meet the aforementioned negative pressure requirement, but as the number of times of extrusion increases, the elasticity of thedrainage tube 18 in the tube placing gap is weakened, and the maximum negative pressure provided by the elasticity of thedrainage tube 18 is reduced; however, in the use process of the multipurpose clinical drainage device, the multipurpose clinical drainage device can be placed at a position lower than a patient, in addition, the drainage adjusting component acts on the middle lower part of thedrainage tube 18, the gravitational potential energy of accumulated liquid in thedrainage tube 18 can relieve the requirement of required negative pressure in the drainage process, the additionally provided negative pressure is smaller in the situation, and even if the elasticity of thedrainage tube 18 in the tube placing gap is weakened, enough negative pressure can be still provided for negative pressure drainage.

Referring to fig. 8 and 9, in the clinical use of the multi-purpose clinical drainage device, the weight of thedrainage bag 19 and the effusion inside the drainage bag is almost all borne by the hangingpart 3, i.e. almost all the weight of thedrainage bag 19 and the effusion inside the drainage bag is finally transmitted to the weighingsensor 16, the weight of the hangingpart 3 and thedrainage bag 19 after installation is constant and constant in the drainage process, so that the weight change sensed by the weighingsensor 16 is all caused by the increase of the effusion in thedrainage bag 19, so that thecontroller 14 can calculate the weight of the effusion actually drained in unit time, i.e. the real-time drainage speed, according to the weight signal continuously fed back by the weighingsensor 16 in real time in the drainage process, and can calculate the accumulated weight increase of the effusion in thedrainage bag 19 from the beginning of the drainage to the present period, i.e. the single real-time drainage quantity, therefore, thecontroller 14 can calculate the real-time drainage speed and the single real-time drainage quantity based on the weight signal continuously fed back by the weighingsensor 16 in real time, which can be realized by adopting the prior art;

based on the working principle adopted by the multipurpose clinical drainage device, the output of two adjacent hydrops has a certain time interval in the drainage process, namely the hydrops flows in a pulse mode, so that the unit time based on which thecontroller 14 calculates and obtains the data of the real-time drainage speed is not too short, and the controller is better to be capable of generating at least two fluid outputs in one unit time; in addition, although the effusion is pulsed in the drainage process, the effusion generally does not bring discomfort to the patient, and the pulse feeling generated in the drainage process can be reduced by additionally arranging a buffer container on thedrainage tube 18.

Referring to fig. 8, when the multipurpose clinical drainage device is used clinically, the drainage bag 19 is fixedly connected with the tail end of the drainage tube 18 in the drainage process, the drainage tube 18 inevitably generates a certain acting force on the drainage bag 19, and the acting force may change along with the deformation of the drainage bag 19, and the force and the change of the force are inevitably picked up by the weighing sensor 16 and fed back to the controller 14, so that the data accuracy of the real-time drainage speed and the single real-time drainage quantity is influenced to a certain extent; however, in the multi-purpose clinical drainage device, before clinical drainage is implemented, the height of the drainage bag 19 can be adjusted through the hanging part 3, so that the part of the drainage tube 18, which is positioned between the lead-out groove 5 and the drainage bag 19, is in a natural extension state, the acting force of the lower end of the drainage tube 18 on the drainage bag 19 can be reduced, and the acting force between the drainage tube 18 and the drainage bag 19 tends to be constant, thereby reducing the influence of the factors on the data accuracy of real-time drainage speed and single real-time drainage quantity to the maximum extent.

As shown in fig. 2, 8 and 9, in the above-mentioned multipurpose clinical drainage device, the weighing sensor 16 can pick up the change state of the weight of the accumulated liquid in the drainage bag 19, and output a weight signal based on the change state, so as to provide a data base for the controller 14 to calculate parameters such as real-time drainage speed, single real-time drainage quantity and the like, and thus, the accuracy of the weight signal output by the weighing sensor 16 is a key factor that affects whether the multipurpose clinical drainage device can accurately control the drainage process; the weight measuring function part in the weight-measuring suspension support assembly 4 can be regarded as a conventional weight measuring mechanism, and as is well known, the weight measuring mechanism can only stably and accurately work in a specific direction, namely, the accuracy of a weight signal output by the weighing sensor 16 can be ensured only when the multi-purpose clinical drainage device is horizontally placed, otherwise, the gravity generated by accumulated liquid in the drainage bag 19 is decomposed, so that the weight signal output by the weighing sensor 16 is inaccurate; generally speaking, with the gradual improvement of ward conditions of medical units, the ground in the ward is relatively flat and tends to be horizontal, so when the multipurpose clinical drainage device is placed on the ground of the ward for use, the technical requirement of horizontal placement can be met, and the weight signal output by the weighing sensor 16 can be ensured to be relatively accurate;

step by step, even if the ground in the ward can not reach the requirement of tending to the level, the adjustment can be realized by the way of arranging articles below thebase 1, so that the multi-purpose clinical drainage device is horizontally arranged, and the accuracy of the weight signal output by the retransmission sensor in the clinical drainage process is ensured.

Referring to fig. 5, 6, 7 and 9, in the above-mentioned multipurpose clinical drainage device, threeelectric feeding mechanisms 9 are respectively connected with the upper movablepressing block 11, the middle movablepressing block 10 and the lower movablepressing block 7, and thecontroller 14 can regulate and control the working states of the threeelectric feeding mechanisms 9, so as to adjust the positions of the upper movablepressing block 11, the middle movablepressing block 10 and the lower movablepressing block 7 in the respective moving strokes, and it is not difficult to implement the above-mentioned technical features by using the prior art in the electromechanical field, and in this embodiment, the above-mentioned technical features are preferably implemented by using the following structures:

as shown in fig. 11, the threeelectric feeding mechanisms 9 have the same structure, and each of them is composed of aservo motor 27, ascrew rod 26 coaxially connected with the output shaft of theservo motor 27, and aguide block 25 in threaded fit with thescrew rod 26, theguide block 25 is installed in theguide slot 24 of theinstallation plate 6, when theservo motor 27 drives thescrew rod 26 to rotate, thescrew rod 26 drives theguide block 25 to move along theguide slot 24, so as to be far away from or close to the fixedpressing block 8; the threeguide blocks 25 are respectively fixedly connected with the upper movablepressing block 11, the middle movablepressing block 10 and the lower movablepressing block 7; the start, stop, rotation direction and rotation angle of the operation of theservo motor 27 are controlled by thecontroller 14;

in the above-mentionedelectric feeding mechanism 9, the required feeding requirement is achieved based on the screw mechanism, and besides, the specific configuration of theelectric feeding mechanism 9 may be implemented by those skilled in the art based on a conventional mechanism such as a crank link mechanism, a cam mechanism, a rack and pinion mechanism, etc., and the corresponding feeding requirement may be achieved.

The multipurpose clinical drainage device adopts an intelligent design, and can realize functions of timed drainage, constant-speed drainage, quantitative drainage and the like according to preset drainage parameters in the clinical drainage operation, so that the aim of full-automatic drainage control is fulfilled, the labor burden is saved, and the safety, stability and accuracy of the drainage operation are improved; the multipurpose clinical drainage device is matched with theconventional drainage bag 19 and thedrainage tube 18 for use, and the existing structures of thedrainage bag 19 and thedrainage tube 18 are not required to be changed, so that the multipurpose clinical drainage device is easier to popularize and use; the multipurpose clinical drainage device has two working modes of normal-pressure drainage and negative-pressure drainage, can meet different drainage operation requirements of pleural effusion drainage, abdominal effusion drainage and the like, and has stronger applicability and wider application range; meanwhile, the multipurpose clinical drainage device has the advantages of small volume, convenient movement, convenient carrying, small occupied space, high flexibility and great clinical popularization value.

Example 2

Referring to fig. 8, in the multi-purpose clinical drainage device disclosed in example 1, it has been clarified that the accuracy of the weighing signal output by the weighingsensor 16 is greatly affected by whether the multi-purpose clinical drainage device is horizontally placed; if the ground levelness is relatively poor, although the problem can be solved by cushioning articles below thebase 1, the operation is troublesome, time and labor are wasted, and therefore, the embodiment is further improved on the basis of the structure of the multi-purpose clinical drainage device disclosed by the embodiment as follows:

as shown in fig. 12 and 13, a firstrotating shaft 30 extending horizontally and backwardly is fixed at the rear side of thesetting plate 6, and a swingingseat 29 is fixed through the firstrotating shaft 30 and can swing left and right with a small amplitude; the upper end of the weight-measuringsuspension support assembly 4 is connected with the swingingseat 29 through the secondrotating shaft 28, so that the weight-measuringsuspension support assembly 4 can swing back and forth in a small range; the firstrotating shaft 30 and the secondrotating shaft 28 are perpendicular to each other; when thedrainage bag 19 is fixed by the hangingpart 3, the weight-measuring typesuspension support assembly 4 is driven by gravity to always maintain a specific direction, and the weight change state of the accumulated liquid in thedrainage bag 19 can be accurately picked up by theweight sensor 16 in the specific direction;

when the multi-purpose clinical drainage device is improved in structure, the weight-measuringsuspension support assembly 4 has an automatic direction adjusting mechanism, even if the multi-purpose clinical drainage device is not horizontally arranged in clinical use, the weight-measuringsuspension support assembly 4 can automatically adjust to and maintain a specific direction through left-right swinging and front-back swinging, so that the weighingsensor 16 can work stably and accurately;

in the improved structure, theswing seat 29 can swing left and right with small amplitude, the weight-measuringsuspension assembly 4 can swing front and back with small amplitude, and the front and back swing and the left and right swing are both small amplitude, which is intended to limit the change of the relative position of the mountingplate 6 and the weight-measuringsuspension assembly 4 within a small range, and avoid the inconvenience for the mounting, carrying and other operations of the multi-purpose clinical drainage device caused by the unstable relative position of the mountingplate 6 and the weight-measuringsuspension assembly 4; the specific swing angle range of the small amplitude has no accurate requirement, and the aim is to ensure that the multipurpose clinical drainage device can stably and accurately work under most ground conditions;

meanwhile, the technical requirements that the weight-measuringsuspension assembly 4 and the swingingseat 29 can only swing back and forth and swing left and right within a small amplitude range are met, and the technical requirements can be easily met by arranging correspondingangle limiting mechanisms 31 between the weight-measuringsuspension assembly 4 and the swingingseat 29 and between the swingingseat 29 and the mountingplate 6;

for the technical requirement that the weight-measuringsuspension support assembly 4 can be automatically adjusted to and maintained in a specific direction under the drive of gravity, when the multipurpose clinical drainage device is manufactured, the specific structural form of the weight-measuringsuspension support assembly 4 is debugged, and a standard operation mode is set for the connection mode of thesuspension part 3 and thedrainage bag 19, so that the technical requirement is realized without difficulty; the specific direction refers to that the gravity generated by the accumulated liquid in thedrainage bag 19 tends to be totally fed back to the weighingsensor 16 under the direction of the weight-measuring typesuspension support assembly 4, so that the weighingsensor 16 can accurately pick up the weight change state of the accumulated liquid in thedrainage bag 19.

Example 3

Referring to fig. 8, drainage is a medical means commonly used in clinical practice at present, the clinical drainage process is mostly performed in a ward, and the multi-purpose clinical drainage device needs to be moved back and forth frequently from ward to ward and from ward to instrument room; when the multipurpose clinical drainage device is used clinically, the whole device can be stably supported by thebase 1, thebase 1 is necessarily large and heavy, the whole multipurpose clinical drainage device is labor-consuming to move integrally and is influenced by thebase 1, the whole volume of the multipurpose clinical drainage device is large, the occupied space is large when the multipurpose clinical drainage device is used, and the flexibility is poor;

generally speaking, the infusion support is a necessary medical device in a ward, the structure is relatively simple, the occupied space is small, and if the multipurpose clinical drainage device can be used with the infusion support after theheavy base 1 part can be removed, a great deal of convenience is brought to the clinical drainage operation; based on the above reasons, the present embodiment has further improvements to the clinical drainage control device disclosed in the foregoing embodiments, and the specific implementation structure is as follows:

as shown in FIGS. 14 and 15, the multi-purpose clinical drainage device further comprises a clampingmember 33 which can be clamped and fixed on thetransfusion rod 37 of the transfusion stand; a combinedseat 36 is arranged at the rear side of the placingplate 6, and the combinedseat 36 is connected with the upper end of theupright post 2 in a detachable way; an assembling mechanism is arranged between the clampingmember 33 and the combinedseat 36, and when the clampingmember 33 is connected with the combinedseat 36, the multipurpose clinical drainage device can be supported by thetransfusion rod 37 to work; the combinedseat 36 and theupright post 2 can adopt a splicing structure to realize the technical purpose of disassembly and assembly, and the disassembly and assembly operation is also convenient;

therefore, as shown in fig. 15, in clinical use, the multi-purpose clinical drainage device can work in cooperation with an infusion support usually provided in a ward without depending on the support provided by thebase 1, so that the multi-purpose clinical drainage device is more convenient to move, more flexible to use and more convenient and faster to operate.

Referring to fig. 14, in the above improved structure, thefastening member 33 and thecombination seat 36 can be connected by the assembling mechanism, which is used to ensure that thefastening member 33 can provide sufficient and stable support for the multipurpose clinical drainage device, as for the prior art, the assembling mechanism has various embodiments, but in order to ensure the stability and the convenience of disassembling and assembling after thefastening member 33 is combined with thecombination seat 36, the assembling mechanism preferably adopts the following design, and the specific structure is:

as shown in fig. 14 and 15, the assembling mechanism is composed of a T-shapedgroove 35 disposed on one side of thecombination seat 36 and a T-shapedrib 34 disposed on the clampingmember 33, the T-shapedgroove 35 extends vertically, the upper end is a blind end, the lower end is an open end, the T-shapedrib 34 and the T-shapedgroove 35 can be combined, and the lower end of the T-shapedrib 34 is provided with a dampingpad 32 for clamping the T-shapedgroove 35;

based on the above structure adopted by the assembling mechanism, the T-shapedrib 34 of the clampingmember 33 is inserted into the T-shapedgroove 35 of the combinedbase 36 from bottom to top, so that the assembling of the combinedbase 36 and the clampingmember 33 is completed, otherwise, the combinedbase 36 and the clampingmember 33 can be separated; when the T-shapedrib 34 and the T-shapedgroove 35 are completely combined, the dampingpad 32 tightly clamps the T-shapedgroove 35 to lock the relative position of the T-shapedrib 34 and the T-shapedgroove 35, thereby preventing the clampingmember 33 from being separated from thecombination base 36.

Referring to fig. 14 and 15, in the above improved structure, the clamping member 33 is used for clamping and matching with the infusion rod 37 to provide a stable support for the multi-purpose clinical drainage device, and as far as the prior art is concerned, the clamping member 33 has various embodiments, for example, a clamping mechanism for clamping the infusion rod 37 may be disposed on the clamping member 33, or a C-shaped clamp may be disposed on the clamping member 33, and fastening screws may be added to the clamping mechanism and the C-shaped clamp, and an anti-slip pad may be added to a contact surface with the infusion rod 37 to improve the stability after the clamping member 33 and the infusion rod 37 are combined; although the clamping piece 33 can meet the basic technical requirement of providing support for the multi-purpose clinical drainage device by adopting the structure, the clamping piece has the defects of not simple structure, not beautiful appearance, troublesome use and the like; meanwhile, generally speaking, the types of infusion supports used by the same medical institution are mostly the same, that is, the diameters of the infusion rods 37 are the same, but no exception exists, and the implementation structure adopted by the clamping member 33 is difficult to be compatible with the infusion rods 37 with different sizes for use, and will certainly form certain limitations in clinical use; therefore, the present embodiment also proposes a novel implementation manner for the clamping member 33, and the specific structure is as follows:

as shown in fig. 16 and 17, a clamping opening 43 for accommodating the transfusion rod 37 is formed in one side of the clamping member 33, two opposite side walls of the clamping opening 43 are respectively provided with a limiting seat 44, a floating holding block 38 is respectively arranged in the limiting seat 44, opposite end portions of the two floating holding blocks 38 are arc-shaped ends 42, end surfaces of the two arc-shaped ends 42 are both arc-shaped and are respectively fixed with an anti-skid rubber pad 39, and the two arc-shaped ends 42 are respectively used for holding two sides of the transfusion rod 37; the floating holding block 38 and the limiting seat 44 are matched through a guide mechanism formed by the sliding chute 40 and the sliding block 41, so that the floating holding block 38 has an oblique floating stroke, when the two floating holding blocks 38 move upwards along respective floating strokes simultaneously, the two arc-shaped ends 42 gradually approach and enter the clamping opening 43, and when the two floating holding blocks 38 move downwards along respective floating strokes simultaneously, the two arc-shaped ends 42 gradually depart and finally retract to the corresponding limiting seats 44; the two limiting seats 44 are respectively provided with a return spring 45 which drives the corresponding floating holding block 38 to return to the uppermost end of the floating stroke;

when the clampingmember 33 adopts the above structure, after the clampingport 43 of the clampingmember 33 is clamped outside theinfusion rod 37, the two floating clasping blocks 38 can clamp and clasp theinfusion rod 37 from two opposite sides of theinfusion rod 37, the weight of the multipurpose clinical drainage device can generate a downward acting force on the clampingmember 33, and the two floating clasping blocks 38 can respectively receive horizontal component force to further clasp theinfusion rod 37, in short, the larger the weight borne by the clampingmember 33 is, the firmer the two floating clasping blocks 38 clasp theinfusion rod 37 is, so that the relative movement between the clampingmember 33 and theinfusion rod 37 can be avoided, and the stability after the clampingmember 33 and theinfusion rod 37 are combined is improved;

meanwhile, because the two floating holding blocks 38 have certain floating strokes, the distance between the two floating holding blocks can be automatically adjusted according to the different diameters of thetransfusion rods 37, the applicability of the clampingmember 33 is improved to a certain extent, and the clamping member can be matched withvarious transfusion rods 37 with different diameters for use.

Example 4

Referring to fig. 4-7, in the clinical drainage process of the multi-purpose clinical drainage device, the upper movablepressing block 11, the middle movablepressing block 10 and the lower movablepressing block 7 squeeze thedrainage tube 18 in the gap between the opposite tubes in different ways to realize the adjustment and control of the drainage state, so that thedrainage tube 18 in the gap between the opposite tubes can be stably matched with the drainage adjusting assembly, which is a necessary condition for ensuring the stable operation of the multi-purpose clinical drainage device; in the multi-purpose clinical drainage device disclosed in the foregoing embodiment, in order to facilitate the combination and separation of thedrainage tube 18 and the drainage regulating assembly, theintroduction groove 12, the lead-outgroove 5 and the front side of the tube placing gap are all open, and there is a risk that thedrainage tube 18 slips off from the front side of the tube placing gap in the drainage process, so as to reduce the stability of the multi-purpose clinical drainage device in operation, in order to solve the above problems, the present embodiment has a further improvement on the multi-purpose clinical drainage device:

as shown in fig. 18 and 19, acover plate 46 is disposed on the front side of theinstallation plate 6, the inner end of thecover plate 46 is rotatably connected to theinstallation plate 6 through arotating shaft 47, twopressing blocks 49 are disposed on one side wall of thecover plate 46, and thecover plate 46 has two station states and can be switched between the two station states by turning over; when thecover plate 46 is turned to a station state, the cover plate covers the pipe placing gap, the upper movablepressing block 11, the middle movablepressing block 10 and the front side of the lower movablepressing block 7, and the twopressing blocks 49 are respectively pressed into the introducinggroove 12 and the leading-outgroove 5 to firmly clamp and fix thedrainage pipe 18; when thecover plate 46 is turned to another station state, it covers the front sides of thedisplay screen 13 and the settingkeys 15; alocking mechanism 48 which can lock thecover plate 46 at two stations respectively is arranged between thecover plate 46 and thesetting plate 6;

therefore, in the drainage process, as shown in fig. 18, the front side opening of the tube placing gap can be plugged by thecover plate 46, and thedrainage tubes 18 led into thegroove 12 and the lead-outgroove 5 are respectively pressed by the twopressing blocks 49, so that thedrainage tubes 18 can be prevented from slipping from the tube placing gap in the drainage process, the working stability of the multipurpose clinical drainage device is improved, meanwhile, thecover plate 46 can also prevent external foreign matters from entering the tube placing gap in the drainage process, and the working accuracy of the multipurpose clinical drainage device is improved; when drainage is not performed, as shown in fig. 19, thecover plate 46 can be used to provide a better protection function for thedisplay 13 and the settingkey 15, so as to prevent thedisplay 13 and the setting key 15 from being damaged during the moving and idle processes of the multi-purpose clinical drainage device.

Referring to fig. 18 and 19, in the above modified structure, alocking mechanism 48 is provided between thecover plate 46 and thesetting plate 6, and thelocking mechanism 48 is used for locking and maintaining thecover plate 46 in a two-station state, that is, when thecover plate 46 is in a one-station state, the relative position of thecover plate 46 and thesetting plate 6 can be locked by thelocking mechanism 48, so that thecover plate 46 is maintained in the station state, and the corresponding function is exerted; based on this, as for the prior art, thelocking mechanism 48 has various embodiments to satisfy the basic functions expected for the locking mechanism, but if the locking mechanism is implemented by the prior art, the prior art has certain disadvantages, or the operation is not convenient enough, and the locking and unlocking are required to be performed manually, or the locking failure is easy to occur, or the mating member is complex, the service life is short, and so on, for this reason, anovel locking mechanism 48 is further provided in this embodiment, and the specific implementation structure thereof is as follows:

as shown in fig. 20, thelocking mechanism 48 includes atongue piece 53 movably limited on thecover plate 46 and two lockingmagnetic sheets 50 installed on theinstallation plate 6, astrong magnet 52 is installed on thetongue piece 53, when thetongue piece 53 is in a reset state, the outer end thereof is exposed outside the outer end of thecover plate 46, and aspring piece 51 for driving thetongue piece 53 to automatically reset is installed in theinstallation plate 6; when thetongue piece 53 is in a reset state and thecover plate 46 is in a station state, thestrong magnet 52 is positioned right above the correspondinglocking magnet piece 50, and at the moment, thestrong magnet 52 and thelocking magnet piece 50 lock the relative position of thecover plate 46 and thesetting plate 6 through adsorption force; when thecover plate 46 is in a working position state, thetongue piece 53 is manually pushed to move inwards, so that thestrong magnet 52 can be staggered with the corresponding lockingmagnetic sheet 50, the locking effect is relieved, and thecover plate 46 can be turned over;

after thelocking mechanism 48 adopts the above structure and adjusts thecover plate 46 to a station state, thestrong magnet 52 and thecorresponding locking magnet 50 lock thecover plate 46 through a large adsorption force, so that thecover plate 46 can play a desired function, although thestrong magnet 52 and the lockingmagnet 50 have a large adsorption force when keeping the opposite direction, the shearing resistance is poor, therefore, when the station of thecover plate 46 needs to be adjusted, thetongue piece 53 can be easily pushed to move inwards, and then thestrong magnet 52 and thecorresponding locking magnet 50 are staggered, and the adsorption force between the two is greatly reduced, so that thecover plate 46 can be easily turned over to adjust the station state; thelocking mechanism 48 has the advantages of ingenious structural design, stable work, easy implementation and no jamming fault, and overcomes the defects of the prior similar technology.
