The specific embodiment
Below in conjunction with accompanying drawing this utility model is described further:
See also Fig. 1, Fig. 1 is the perspective view of a kind of embodiment of this utility model.It is a kind of percutaneous thyrocricoid puncture trocar, comprise soft tube 1, puncture needle 2, interlock line 3 and puncture needle operating parts 4 with certain rigidity, described interlock line 3 one ends link to each other with described puncture needle operating parts 4, the other end and described puncture needle 2 join, on the end face of described soft tube 1, establish soft tube fixing head 5 away from end of puncture needle needle point 21 and the soft tube 1 between the described puncture needle operating parts 4, on described soft tube fixing head 5, be provided with standard trachea union joint 6, described standard trachea union joint 6 communicates with described soft tube 1 by described sleeve pipe fixing head 5, on the described soft tube 1 close tube wall of syringe needle 21, be provided with axial consistent oval or rectangular flute profile side opening 11 with soft tube 1, after being stopped up by the secret thing of patient's branch with the inlet end that prevents soft tube 1, can also continue ventilation by side opening 11.On described soft tube fixing head 5, also be provided with fixing band connector 51.On described fixing band connector 51, be provided with the connecting hole 52 that connects for fixing band 7.In described connecting hole 52, be provided with fixing band 7.Described puncture needle 2 and interlock line 3 are enclosed within the described soft tube 1 after passing trachea union joint 6, soft tube fixing head 5 successively.Among the figure, puncture needle 2 dots with the interlock line 3 with certain rigidity.
In this utility model, described standard trachea union joint 6 is plastics, is modular connection, it can with respirator, balls etc. provide air machinery to be connected.Described soft tube 1 can be adopted the silica gel trachea, and its length is preferably 15cm, diameter 0.50cm, wall thickness 0.15cm, 5cm plays bending apart from the soft tube tail end, and the best 3cm of sweep is long, 90 ° of cambers, straight part 7cm is long, and is gradually thin apart from head end 2cm tube wall, opening part thickness of pipe wall 0.10cm.Described puncture needle adopts rustless steel to make, long 10cm, and diameter 1.6cm, 90 ° of cambers, afterbody connects plastic cap, and head is sharp-pointed.Described interlock line preferably adopts the guiding principle silk thread of multiply hinge joint, and it had both had certain rigidity, had certain flexibility again; Described soft tube fixing head 5 is that rubber is made apart from gas-tpe fitting 3cm.Described fixing band 7 is cotton products, length 50cm.One end is fixed on the fixing band connector 51, and the other end is around the fixing soft tube 1 of neck.Described puncture needle operating parts 4 can adopt plastic.The side opening 11 of described tracheal casing pipe is respectively established a hole apart from soft tube head end 3cm and 4cm place, and long 0.50cm is wide by 0.30.The vacuum-packed enclosing sterilizing of a whole set of percutaneous thyrocricoid puncture trocar.
During use, when last patient respiration road blocks, through mouth to mouth breathing, when thorax extruding or face shield pressure-vent can not be improved anoxia, ring first film place that can patient uses this utility model puncture ventilation, use patient's head layback position, to encircling first film place behind the sterile drape of anterior region of neck, hands of operator is with the needle point perpendicular alignmnet patient's of puncture needle ring first film place, and another hands is by puncture needle operating parts 4, by the vertical percutaneous puncture of interlock line 3 percutaneous ring first Membrane cover bobbins, have about inserting needle 0.5cm break through sense after, puncture needle 2 pulled back withdraws from 1cm, again soft tube is tilted 30 ° to fill in the wound that the patient is punctured pin 2 after, then, with the oblique underlying 4～6cm of soft tube, puncture needle 2 is all withdrawed from, reuse fixing band 7 is fixing with soft tube 1 around neck again again, the extruding thorax has air-flow to come out, and confirms that conduit is in trachea.Push or connect simply respirator, respirator etc. with mouth expiration, thorax, implement ventilation and improve the oxygen confession.
