Specific embodiment
Embodiments of the present invention are illustrated by particular specific embodiment below, those skilled in the art can be by this explanationContent disclosed by book is understood other advantages and efficacy of the present invention easily.
It should be clear that this specification structure depicted in this specification institute accompanying drawings, ratio, size etc., only to cooperate specification to be taken offThe content shown is not intended to limit the invention enforceable qualifications so that those skilled in the art understands and reads, thereforeDo not have technical essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size are not influencing the present inventionUnder the effect of can be generated and the purpose that can reach, it should all still fall in disclosed technology contents and obtain the model that can coverIn enclosing.Meanwhile cited such as "upper", "lower", " left side ", the right side in this specification ", the term of " centre ", be merely convenient to chatThat states is illustrated, rather than to limit the scope of the invention, relativeness is altered or modified, and is changing skill without essenceIt is held in art, when being also considered as the enforceable scope of the present invention.
Embodiment 1
The present embodiment provides a kind of chest drainage conduits, and as shown in Figs. 1-2, which includes outer tube 1, inner tube2 and suction nozzle 3, the suction nozzle 3 be connected to the front end of said inner tube 2, the outer tube 1 is set in the periphery of 2 front of said inner tube, instituteState inner tube 2 can slide back and forth in the outer tube 1, and the suction nozzle 3 has contraction state and expansion state, and the suction nozzle 3 accommodatesIt is in contraction state when 1 inside of outer tube, the suction nozzle 3 after 1 forward slip of outer tube of said inner tube 2 is in internal diameter by rearSuccessively widened expansion state forward offers sucker 4 on the side wall of 1 front end of the suction nozzle 3,2 front end of inner tube and outer tube, describedMultiple diameters of the suction nozzle 3 including spring-backed quill 5, from the front to the back successively in spring-backed quill 5 are successively increased and can radially be pressedThe wave spring ring 6 of contracting and more connecting filaments 7 for connecting adjacent wave spring ring 6.
The present embodiment chest drainage conduit usage mode is as follows: the front end of suction nozzle 3 and inner tube 2 being accommodated in outer tube 1 firstIn, by squeezing the periphery of wave spring ring 6, the wave crest in eminence can be moved up, and the trough in lower can be downwardMobile, the diameter of wave spring ring 6 reduces, so that suction nozzle 3 be enable circumferentially to be compressed in outer tube, is then cut by chestIt mouthful protrudes into thoracic cavity, 2 rear end of inner tube connects drainage bag or drainage bottle, when chest drainage conduit protrudes into purpose position, such as protrudes intoMidaxilla/rear line 6-8 intercostal carries out drain, the 2nd intercostal of linea medioclavicularis is exhausted or thoracic cavity minimum point carries out apocenosis, thisWhen, by opposite stretching outer tube 1 and inner tube 2, i.e., one pulls outer tube 1, and another pulls inner tube 2, and makees opposite directionActive force, i.e. inner tube 2 pushes away to inside of human body, and outer tube 1 is drawn to human external, both makes to generate and misplaces and make suction nozzle 3 from outerIt is stretched out in pipe 1, wave spring ring 6 is expanded due to losing the limitation of outer tube 1 at this time, and suction nozzle expansion is effectively prevent in horn-likeThe blocking of drainage catheter end, and if drainage catheter end is blocked, stretch outer tube 1 and inner tube 2 by opposite suction nozzle carried outDredging, it is convenient and efficient.
Embodiment 2
The present embodiment provides suction nozzles, as shown in Fig. 2, the lesser opening of the opening and diameter that the suction nozzle 3 is relatively large in diameter is equalIt is rounded and supported by the elastic resin circle 8 in insertion spring-backed quill 5, two elastic resin circles 8 by the connecting filament 7 withAdjacent wave spring ring 6 is connected, and the spring-backed quill 5 is flexible latex or rubber.It can make to inhale by the way that elastic resin circle is arrangedHead both ends are held round, and are released from outer tube so as to successfully be accommodated in outer tube neutralization.
Embodiment 3
The present embodiment provides outer tubes and inner tube, as shown in Figure 1, the length of the outer tube 1 is 10-40cm, said inner tube 2Length be greater than the outer tube 1, the outer wall of said inner tube 2 is provided with for limiting the mobile stop collar 13 of outer tube 1, the outer tube1 rear end when pulling back to the stop collar 13 suction nozzle 3 be completely exposed to outside the outer tube 1.Said inner tube 2 and instituteIt states outer tube 1 and is each independently pitch tube.It can prevent suction nozzle 3 from discharging excessively by the way that stop collar is arranged, it can be with by pitch tubeMake inner and outer tubes that there is certain elasticity and rigidity, can smoothly enter into thoracic cavity.
Embodiment 4
The present embodiment provides cleaning bracing wires, as shown in Figure 1, the chest drainage conduit further includes preventing said inner tube 2 stifledThe cleaning bracing wire of plug, the cleaning bracing wire include bracing wire main body 9 and elastic ball 10, and the elastic ball 10 is located at outside the sucker 4Portion, one end of the bracing wire main body 9 is connected with the elastic ball 10, the other end passes through said inner tube 2 and extends to said inner tube 2Outside rear end.The elastic ball 10 is latex balloon, and the bracing wire main body 9 is cotton thread or resin thread.It, will after inner tube is blockedInner tube is pulled up from drainage bag or drainage bottle, then bracing wire main body is pulled to make to sequentially pass through sucker and inner tube in elastic sphereInner tube is dredged, it is convenient and efficient.
Embodiment 5
The present embodiment provides fixing pipes, as shown in Figure 1, the periphery of the outer tube 1 is also arranged with for being embedded in woundFixing pipe 11 is connected to the 11 rear end periphery of fixing pipe for being bonded the annular pasting sleeve 12 of skin, the annular pasting sleeve12 front side is covered with sterilization glue layer.Fixing pipe is inserted and fixed in notch when in use, then passes through sterilization glue layerIt is mutually pasted with the skin of notch outside, to fix fixing pipe, prevents fixing pipe mobile, so that outer tube and inner tube be made to cutIt prevents from encountering notch and causing pain when mobile or vibration at mouthful.Annular pasting sleeve can using medical adhesive tape material preparation andAt.
Although above having used general explanation and specific embodiment, the present invention is described in detail, at thisOn the basis of invention, it can be made some modifications or improvements, this will be apparent to those skilled in the art.Therefore,These modifications or improvements without departing from theon the basis of the spirit of the present invention are fallen within the scope of the claimed invention.
