Abstract
Show pressure syringe, including the ware body and push rod, being equipped with a branch pipe on the ware body, being equipped with sealed bladder bubble on this branch pipe, be equipped with the round arch on the ware body tail end inner wall, it is protruding that the outer fringe is equipped with a sphere in the middle part of the strengthening rib of push rod, is equipped with a notch below the protruding place muscle face of this sphere, the utility model has the advantages of the puncture success rate is high, the security is strong, with low costs, easy operation, do benefit to new hand and use and make things convenient for the teaching, even the new life of medical college also can skillfully accomplish vertebra dura mater puncture operation, can extensively be applicable to various medical institution's surgery anesthesia and clinical examination treatment.
Description
Technical field
This utility model relates to medical medical instruments field, and what be specifically related to a kind of clinical epidural anesthesia use shows pressure injection emitter.
Background technology
Modern medical service, when carrying out local or general anesthesia to patient, needs first to puncture to vertebra dura mater, makes syringe needle enter vertebra epidural space.Sting shallow, vertebra dura mater cannot be penetrated, cannot normally anaesthetize; Sting dark, again easy Spinal Cord or nerve, sensation and the experience of operator are depended in puncture success or not completely.
On October 31st, 2012, publication number is that the Chinese utility model patent of CN20250589U discloses one " cavum epidural puncture high-drag push rod vesicle indication injector ", this device comprises body, syringe needle and push rod and it is characterized in that: on described body or on body mouth or syringe needle root be provided with an arm, this arm is provided with a sealing vesicle, push away before push rod, sealing vesicle expands, and has following relation: (P1-P0) × S≤Fmax, and wherein P1 is sealing vesicle inner fluid pressure; P0 is atmospheric pressure; S is the projected area of push rod seal face on push rod cross section; Fmax is the maximum static friction force between push rod and body inwall.Above-mentioned relation is embodied in: push away before push rod, seal vesicle expand after, unclamp push rod, push rod stands fast.Vesicle elasticity or flexible material are made, waterproof, airtight.Described arm is arranged on body leading portion sidewall, and communicates with device cavity; As optimization, described arm is arranged on body mouth sidewall, and communicates with device cavity; As optimization, described arm is arranged on syringe needle heel sidewall, and communicates with needle lumen.This utility model when clinical concrete practical operation, vesicle become flat while move after push rod, thus can not judge accurately due to puncture put in place after the vesicle that causes of negative pressure become flat or become flat owing to moving the vesicle caused after push rod.
On JIUYUE 10th, 2003, publication number is that the Chinese utility model patent of CN2571331Y discloses " a kind of cyst display pressure-preserving syringe for epidural space puncture ", this device comprises body (i.e. syringe), before this body, bottom is provided with communicating pipe, be connected with vesicle outside communicating pipe, body rearward end is provided with push rod locating groove device.Puncture needle operationally, is first connected on body by aforementioned patent, sucks liquid or gas, takes off vesicle lid; Then puncture needle head is thrust human body subcutaneous; Pushing syringe push rod makes vesicle heave again.Before continuation inserting needle, because both hands will leave push rod afterbody, the pressure in vesicle can promote push rod backward, and vesicle is suppressed automatically.In order to keep vesicle expanded state, devise draw-in groove push rod is fixed, make vesicle pressure can not promote push rod backward, when both hands leave, vesicle can keep heaving state, last hand-held body slowly advances puncture needle, when vesicle becomes flat suddenly, represent that puncture needle head successfully thrusts the epidural space of low pressure.This device instead of the feel of people, changes and shows puncture successfully with the automatic continuous monitoring pressure of vesicle, and puncture success rate improves, and the convenience of use is also improved.But its push rod positioner complicated operation, uses inconvenience, and operator can be caused to grip shakiness, affects operating accuracy.
Utility model content
The purpose of this utility model is that the one designed to solve the problem is safer, convenient, structure simply shows pressure injection emitter.
This utility model solves the technical measures that its technical problem takes:
Show pressure injection emitter, comprise body and push rod, described body is provided with an arm, this arm is provided with a sealing vesicle, it is protruding that body tail end inwall is provided with a circle, and in the middle part of the reinforcement of push rod, outer rim is provided with a hemisphere jut, below this muscle face, hemisphere jut place, be provided with a notch.
Above-mentionedly show pressure injection emitter, its feature is arranged on body leading portion sidewall at described arm, and communicates with device cavity.
The beneficial effect that this utility model has is: puncture success rate is high, high safety, cost are low, simple to operate, be beneficial to new hand uses and facilitates the advantage of imparting knowledge to students, even the new life of medical college also skillfully can complete the operation of vertebra dura mater puncture, surgery anesthesia and the Clinical Laboratory treatment of various medical institutions can be widely used in.

Detailed description of the invention
As shown in Figure 1-2, show pressure injection emitter, comprise body 1 and push rod 2, described body 1 is provided with an arm 3, and this arm 3 is provided with a sealing vesicle 4, and body 1 tail end inwall is provided with a circle projection 5, in the middle part of the reinforcement 6 of push rod 2, outer rim is provided with a hemisphere jut 7, below this muscle face, hemisphere jut 7 place, be provided with a notch 8, arm 3 is arranged on body 1 leading portion sidewall, and communicates with body 1 inner chamber.
First syringe needle is connected on body 1 during clinical concrete operations, pull push rod 2, by medicine or liquid inhaler body 1, grip body 1 inserting needle, arrive the compact tissue near spinal column, then thumb promotes push rod 2, in pushing course, sealing vesicle is slowly heaved, when hemisphere jut 7 meets with protruding 5, due to thumb thrust, there is deformation in the notch 8 below muscle face, hemisphere jut 7 place, thus make hemisphere jut 7 can pass through protruding 5 smoothly, now thumb leaves push rod 2 tail end, due to sealing vesicle 4 pressure retraction, push rod 2 is caused to have a thrust backward, but this thrust is not enough to make notch 8 that deformation occur, thus hemisphere jut 7 can not cross protruding 5, gmatjpdumamics between hemisphere jut 7 and protruding 5 is in a kind of dynamic balance state with the retraction force sealing vesicle 4, sealing vesicle 4 is still in expanded state, again grip body 1 slowly inserting needle, when sealing vesicle 4 and becoming flat suddenly, represent that syringe needle successfully thrusts epidural space, namely puncture successfully.
Be more than preferred embodiment of the present utility model, all changes done according to technical solutions of the utility model, when the function produced does not exceed the scope of technical solutions of the utility model, all belong to protection of the present utility model.
