Specific embodiment
Technical solution in order to enable those skilled in the art to better understand the present invention, with reference to the accompanying drawing and specific embodiment partyFormula elaborates to the present invention.
As shown in Figure 1, the embodiment of the present invention discloses a kind of atomization physical therapy equipment with successive administration function, atomization reasonTreating device can be used for providing the drug of atomization for the patient with respiratory disease, to allow medicament to directly act on affected area,To make disease be eased or cure.The atomization physical therapy equipment of the successive administration function include: medical liquid container, kinetic pump 20,Atomising mechanism 30 and liquid storage mechanism 40.Medicine source container 10 can be made of materials such as plastics, glass, be used to hold the medicine of liquidObject；Power mechanism is connected in medicine source container 10 by the first conduit 51, and the first conduit 51 stretches to the medicine in medicine source container 10The liquid level of object is hereinafter, the operation of kinetic pump 20 can draw the drug in medicine source container 10 by the first conduit 51.Atomising mechanism 30It can will feed drug therein to be atomized, which is additionally provided with cover, and the cover is for be located in patient facePortion, the drug supply patient that will be atomized, so that patient be facilitated to suck the drug being atomized, which passes through the second conduit52 are connected to kinetic pump 20, the kinetic pump 20 drug of the liquid of absorption supplied by atomising mechanism 30 by the second conduit 52 so thatIt is medicinal atomized.Liquid storage mechanism 40 includes a shell 41, is divided into a variable chamber in the shell 41, the variable chamberCharacteristic is: enable to the volume of variable chamber to increase into the indoor drug of variable chamber, meanwhile, it is indoor into variable chamberDrug will receive extruding and have certain pressure；The variable chamber is connected to by a branch 53 with the second conduit 52.In this way, dynamicThe initial phase of 20 operation of power pump, the drug drawn by kinetic pump 20, a part enter atomising mechanism 30 by the second conduit 52It is atomized, another part, is entered in the variable chamber of shell 41 by branch 53, so that some drugs are stored in variable chamberIn room, and variable chamber is constantly forced to increase volume to accommodate more drugs simultaneously；When the volume of variable chamber increases to poleIn limited time, whole drugs that kinetic pump 20 is drawn are entered in atomising mechanism 30 by the second conduit 52.In medicine source container 10After drug is used up, kinetic pump 20 can not provide drug for atomising mechanism 30, at this point, the indoor drug of variable chamber is logical with certain pressureCross branch 53, the second conduit 52 enters in atomising mechanism 30.
The advantage of above-described embodiment is: after the drug in medicine source container 10 is used up, liquid storage mechanism 40 replaces medicine source to holdDevice 10 and kinetic pump 20, and be that atomising mechanism 30 provides the drug of liquid, so as to be provided for atomising mechanism 30 is lastingDrug, with for medicine source container 10 integral replacing or being refilled with for drug gain time.
To prevent liquid storage mechanism 40 when providing drug for atomising mechanism 30, drug reflux enter in kinetic pump 20 (or evenBy 20 reflux of kinetic pump to the first conduit 51), in a preferred embodiment of the invention, as shown in Figure 1, branch 53 and dynamicIt is additionally provided with switch valve 70 on the second conduit 52 between power pump 20, when kinetic pump 20 is run, opens switch valve 70, when dynamicWhen 20 operation of power pump stops, closing switch valve 70.In this way, when kinetic pump 20 is in the phase for drawing drug from medicine source container 10Between, the drug drawn can smoothly enter in atomising mechanism 30 by the second conduit 52, and when the drug in medicine source container 10Use up and kinetic pump 20 it is out of service when, switch valve 70 close so that the drug flowed out from liquid storage mechanism 40 will not reflux to dynamicPower pump 20 or the first conduit 51.Preferably, switch valve 70 is the solenoid valve controlled by electric signal.
It can make in shell 41 there are many variable volume cavity generation types of formation These characteristics, preferably at of the invention oneIn embodiment, as shown in figure 3, liquid storage mechanism 40 further includes elasticity segmentation film 42, the first spring 44；Elasticity segmentation film 42 is used for will41 inside division of shell is formed as above-mentioned variable chamber at upper chamber 461 and lower chambers 462, lower chambers 462；Elasticity segmentation film42 middle part is formed with pushing and pressing part 43, and the first spring 44 is set in upper chamber 461, and both ends are respectively used to abut 41 He of shellPushing and pressing part 43, in which: the top of shell 41 offers through-hole 411, and through-hole 411 is for being connected to upper chamber 461 with outside air.
The course of work of liquid storage mechanism 40 provided by the above embodiment are as follows:
In the initial stage that kinetic pump 20 is run, as shown in figure 4, the drawn drug a part of kinetic pump 20 is led via secondPipe 52 is directly entered atomising mechanism 30 and is atomized, and another part enters the lower chambers 462 of shell 41 via branch 53, underThe drug of chamber 462 forces elasticity segmentation film 42 towards 461 direction stretcher strain of upper chamber because volume constantly increases, meanwhile, it pushes awaySupport block 43 is synchronous to be moved towards upper chamber 461, and accordingly compression, the first spring 44 are formed by anti-pushing and pressing part 43 to the first spring 44Active force makes the drug in lower chambers 462 have certain pressure, and the container in upper chamber 461 is with 462 container of lower chambersIncrease and reduce, the gas in upper chamber 461 is discharged by through-hole 411, to facilitate lower chambers 462 to increase volume.
When the volume of lower chambers 462 increases to the limit, that is, when lower chambers 462 can not accommodate more medical fluids again, powerThe drug that pump 20 is sucked all passes through the second conduit 52 and enters in atomising mechanism 30.
After the drug in medicine source container 10 is all drawn (drug is used up), kinetic pump 20 can not be from medicine source container 10Drug is drawn, at this point, the second conduit 52 is switched on and off the cut-off of valve 70, as shown in figure 5, in the lower chambers 462 with certain pressureDrug is fed into the second conduit 52, and enters in atomising mechanism 30 via the second conduit 52, constantly flows from lower chambers 462 in drugDuring out, the elasticity segmentation continuous elastical retraction of film 42, the first spring 44, which constantly resets, to be stretched out, the volume in lower chambers 462Reduce.
It is drug supply pressure in reduction lower chambers 462 in the pressure difference originally between latter stage, that is, for that can make to supplyPressure is steady as far as possible, keeps the coefficient of elasticity of the first spring 44 small as far as possible, and compression degree is big as far as possible, and makes elasticity segmentation film 42Elasticity modulus is small as far as possible, in this way, the telescopic process of elasticity segmentation film 42 is smaller on drug pressure influence, and the first spring 44 is being stretchedIt is smaller to the reaction force variation of pushing and pressing part 43 when contracting, to keep the pressure change of the drug in lower chambers 462 small.In this way, working asWhen the supply pressure variation of drug is smaller, the variation for being supplied to the flow of atomising mechanism 30 also accordingly becomes smaller, so as to be mistChange mechanism 30 and the drug of the more stable liquid of flow is provided.
The advantage of above-described embodiment is:
1, the elasticity modulus of film 42 can be divided by the coefficient of elasticity and elasticity that the first spring 44 is arranged, so that drugSupply pressure keeps opposite stabilization during entire supply, that is, supply pressure is more constant.
2, elasticity segmentation film 42 is compliant member, (should when entering the pressure of drug of lower chambers 462 and generating larger fluctuationFluctuation may be caused by the operation power swing of kinetic pump 20), elasticity segmentation film 42 can mitigate the pressure by autogenous shrinkageFluctuation.
In a preferred embodiment of the invention, as shown in figure 3, be additionally provided in lower chambers 462 reticle 45 withIn lower chambers 462 are divided into the first sub-chamber 4621 and the second sub-chamber 4622；Wherein: it is unidirectional that first is installed in reticle 45Valve 451 and second one-way valve 452；The inlet and outlet of first check valve 451 respectively corresponds and the first sub-chamber 4621 and secondSub-chamber 4622 is connected to；The inlet and outlet of second one-way valve 452 respectively corresponds and the second sub-chamber 4622 and the first sub-chamber4621 connections.In the present embodiment, when kinetic pump 20 is run, branch's drug initially enters the first sub-chamber 4621, thenIt is stored by the first check valve 451 into the second sub-chamber 4622；And when kinetic pump 20 is out of service, the second sub-chamberThe drug stored in 4622 can be such that second one-way valve 452 opens under pressure, so that drug be made to enter the first sub-chamber4621, and enter atomising mechanism 30 by branch 53, the second conduit 52.
In a preferred embodiment of the invention, such as Fig. 2 and as shown in connection with fig. 7, between branch 53 and atomising mechanism 30The second conduit 52 on be provided with flow restriction body 60；Deflector hole is offered on flow restriction body 60, which is used for warpThe drug crossed the second conduit 52 and enter atomising mechanism 30 carries out flow restriction.That is, flowing through the drug of the second conduit 52After flowing through deflector hole, flow is limited by deflector hole, from deflector hole flow out drug flow become smaller so that drug supplyAmount generally conforms to the demand of atomising mechanism 30.
As what is discussed, liquid storage mechanism 40 provided by above-described embodiment passes through the bullet that the first spring 44 is rationally arrangedThe elasticity modulus of property coefficient and elasticity segmentation film 42 can make the supply pressure of drug keep relative stability, however, due to the storageThe pressure controling mode of liquid mechanism 40 is opened loop control, that is, there is no according to the actual pressure of the drug in the second conduit 52 intoRow control, so that the precision of the control administration pressure of liquid storage mechanism 40 is not very high.To be difficult to make drug with constant flowSupply atomising mechanism 30.
To solve the above problems, in a preferred embodiment of the invention, such as Fig. 2 and as shown in connection with fig. 6, supplying branchConstant current mechanism 80 is additionally provided on 53；Constant current mechanism 80 is according to the second conduit 52 between flow restriction body 60 and atomising mechanism 30The pressure control of interior drug flows into the flow of the drug in atomising mechanism 30 from storing mechanism, so as to flow into atomising mechanism 30Drug flow constant.Specifically, constant current mechanism 80 includes: keeping body 81, slide cores 82, feed liquor bend 85, feed liquorBend 85 goes out liquid bend 86, second spring 84, the first control channel 87, the second control channel 88 and control piper 54.ItsIn, sliding cavity is offered in keeping body 81；Slide cores 82 are set in sliding cavity and can slide along sliding cavity, and slide cores 82 willSliding cavity is divided into the first closing chamber 831, the second closing chamber 832 and is isolated with the first closing chamber 831 and the second closing chamber 832Diversion cavity 833；Perforation to diversion cavity 833, feed liquor bend 85 passes through branch 53 and cavity of resorption outside 85 self-sustaining body 81 of feed liquor bendRoom 462 (or variable chamber) connection；Perforation is to diversion cavity 833 outside 86 self-sustaining body 81 of liquid bend out, so that lower chambers 462Drug in (or variable chamber) can enter liquid bend 86 by sliding cavity, and liquid bend 86 passes through branch 53 and second outConduit 52 is connected to, in this way, liquid bend 86 is connected to feed liquor bend 85 by means of the formation of diversion cavity 833 out, second spring 84 is arrangedFor pushing against slide cores 82 in the second closing chamber 832；First control channel 87 is for being connected to the first closing chamber 831 and liquid outBend 86；It penetrates through outside second control channel, 88 self-sustaining body 81 to the second closing chamber 832；Control piper 54 is used for atomizerThe second conduit 52 between structure 30 and flow restriction body 60 is connected to the second control channel 88.And: make slide cores 82 towardsWhen two closing chambers 832 are slided, the passage section for flowing through feed liquor bend 85 with liquid bend 86 out can be reduced, make slide cores 82 in courtWhen first closing chamber 831 is slided, it is capable of increasing the passage section for flowing through feed liquor bend 85 with liquid bend 86 out.The cunning of slide cores 82The size relation of dynamic direction and passage section can be realized by such as flowering structure: slide cores 82 control out liquid bend 86 by slidingIt penetrates through to the opening 861 of the cavity wall of diversion cavity 833, when slide cores 82 are slided towards the second closing chamber 832, so that opening 861 subtractsIt is small, when slide cores 82 are slided towards the first closing chamber 831, so that opening 861 increases, in this way, the aperture of the opening 861 is just formedFlow through by drug the passage section of directed cavity.
Constant current mechanism 80 is in the course of work that liquid storage mechanism 40 is when atomising mechanism 30 provides drug are as follows:
When the drug in medical liquid container is used up, kinetic pump 20 is out of service, and liquid storage mechanism 40 is that atomising mechanism 30 provides medicineWhen object, the drug in lower chambers 462 flows out, and enters in feed liquor bend 85, and drug flows into diversion cavity via feed liquor bend 85833, and flow through diversion cavity 833 and enter liquid bend 86, and enter the second conduit 52 by going out liquid bend 86, in the second conduit 52In flow through the deflector hole of flow restriction body 60 after, into atomising mechanism 30, meanwhile, drug a part is as control after flowing through deflector holeLiquid processed enters the second closing chamber 832 by control piper 54, and the drug in liquid bend 86 enters first by control channel outClosing chamber 831.In this way, slide cores 82 remain stationary state, second spring 84 when the drug pressure in lower chambers 462 is constantAnd the second drug in closing chamber 832 is equal to the drug in the first closing chamber 831 to slide cores 82 to the thrust of slide cores 82Thrust.
When the drug in lower chambers 462 due to certain reason (for example, accelerating) upwards suddenly after shell 41 is appliedWhen pressure increases, the pressure for flowing through out the drug of liquid bend 86 is increased accordingly, so that the pressure in the first closing chamber 831 increases,The balance of slide cores 82 is broken, and slide cores 82 are moved towards 832 direction of the second closing chamber, so that 861 apertures of opening reduce, thusUsing the drug pressure in liquid bend 86 can lower, thus overcome pressure jump and caused by flow unexpected increase,So that flow through out liquid bend 86, the second conduit 52, deflector hole pressure will not generate the fluctuation of larger rising, to make to flowThe flow for entering atomising mechanism 30 does not have biggish rising fluctuation.
Correspondingly, when the drug in lower chambers 462 is because certain reason (for example, accelerate downwards suddenly after shell 41 is appliedMovement) and when reducing pressure, slide cores 82 are slided towards the first closing chamber 831, to flow through out liquid bend 86, the second conduit52, the pressure of deflector hole will not generate the fluctuation of larger decline.
Above-mentioned is the course of work of constant current mechanism 80 when being directed to pressure jump, as can be seen from the above analysis, constant current mechanism80, which can be effectively reduced pressure oscillation, gives drug bring flowed fluctuation.
It will be recalled from above that liquid storage mechanism 40 is with service time, the pressure for supplying drug is constantly reduced, although can lead toThe coefficient of elasticity for crossing the first spring 44 of setting can reduce the amplitude of reduction, but since liquid storage mechanism 40 is not to be directly used in controlThe flow of medical fluid, but indirectly by control pressure keep flow stable as far as possible, therefore, to flow constant degree requirement compared withHigh occasion, liquid storage mechanism 40 are difficult to meet the requirements.
And above-mentioned constant current mechanism 80 can meet the occasion for having high requirement to drug flux, analyze from whole, it is slidingFor dynamic core 82 in stress balance, no matter which kind of position is slide cores 82 be in, drug pushing away to slide cores 82 in the first closing chamber 831Power is consistently equal to thrust of the drug in the second closing chamber 832 to the thrust of slide cores 82 with second spring 84 to slide cores 82.And the pressure of drug is equal to drug and enters the pressure before deflector hole in the first closing chamber 831, and the drug in the second closing chamber 832Pressure be equal to the pressure of drug flow out from deflector hole, in this way, pressure difference of the difference of the two equal to deflector hole both ends, if by theIt is coefficient of elasticity spring small as far as possible that two springs 84, which are selected, in this way, when slide cores 82 are when being in different location, second spring 84It hardly changes to the thrust of slide cores 82, in this way, the pressure difference at deflector hole both ends hardly changes.ToSo that the flow by deflector hole is more constant, so as to provide more constant drug for atomizer.
In a preferred embodiment of the invention, such as Fig. 2 and as shown in connection with fig. 7, a region of the inner wall of deflector holeFlexible pouch is covered, plug is equipped on flow restriction body 60, plug is by pushing against elastic pouch so that elastic pouch protrusionIn the inner wall of pilot hole to reduce the passage section that drug flows through deflector hole；Wherein: the outside of flow restriction body 60 is additionally provided withWith the coaxial opposite spinner of plug；Spinner and the opposite end of plug are respectively arranged with magnet；Two magnets are by two arcsMagnetic section docks to form annular, and two arc magnetic section opposite poles of each magnet are towards identical, to be changed by rotating spinnerThe relative superposition degree of two magnet like poles to change magnetic repulsion between the two, and then changes plug and stretches out water conservancy diversionDegree in hole, and then change the degree that elastic pouch protrudes from deflector hole, it can finally change the medicine for limiting and flowing through deflector holeThe passage section of the flow of object.
The advantage of above-described embodiment is:
1, the passage section of deflector hole is variable, to adjust by the passage section for changing deflector hole and enter atomising mechanismThe flow of 30 drug.
2, two magnets in the present embodiment, which only pass through to relatively rotate, can change magnetic repulsion between the two, and existing skillThe magnet of mutually left and right in art need to could change magnetic repulsion between the two by the relative distance between changing, becauseThis, the mode for changing magnetic repulsion in the present embodiment can more save installation space.
Above embodiments are only exemplary embodiment of the present invention, are not used in the limitation present invention, protection scope of the present inventionIt is defined by the claims.Those skilled in the art can within the spirit and scope of the present invention make respectively the present inventionKind modification or equivalent replacement, this modification or equivalent replacement also should be regarded as being within the scope of the present invention.
