Abstract
Pressure syringe is shown to silica gel friction formula including the ware body and push rod, is equipped with a branch pipe on the ware body, is equipped with sealed bladder bubble on this branch pipe, and the reason is equipped with and holds the groove on the ware body tail end separation blade, and the notch runs through the separation blade, holds the inslot and has placed silica gel, and two non -conterminous strengthening rib lateral surface edges are the cockscomb structure on the push rod, and the branch pipe setting is on ware body anterior segment lateral wall to communicate with each other with ware internal chamber, 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 the silica gel friction-type being 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, the simple silica gel friction-type of structure shows pressure injection emitter.
This utility model solves the technical measures that its technical problem takes:
Silica gel friction-type shows pressure injection emitter, comprise body and push rod, body is provided with an arm, this arm is provided with a sealing vesicle, it is characterized in that body tail end catch upper limb is provided with containing tank, notch runs through catch, is placed with silica gel in containing tank, and on push rod, non-conterminous two reinforcement lateral surface edges are zigzag.
Above-mentioned silica gel friction-type shows pressure injection emitter, it is characterized in that arm is arranged on body leading portion sidewall, 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
Silica gel friction-type shows pressure injection emitter, comprise body 1 and push rod 2, body 1 is provided with an arm 3, this arm 3 is provided with a sealing vesicle 4, and body 1 tail end catch 5 upper limb is provided with containing tank 6, and notch runs through catch 5, silica gel 7 is placed with in containing tank 6, on push rod 2, non-conterminous two reinforcement 8 lateral surface edges are zigzag 9, and 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, rotating push-rod 2 makes do not have reinforcement 8 lateral border of zigzag 9 just to silica gel, then push rod 2 is pulled, 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 4 is slowly heaved to suitable size (diameter about 1 ~ 2 centimeter), rotating push rod 2 gently, when having the reinforcement of zigzag 9 and silica gel vertically, thumb leaves push rod 2 tail end, now due to the frictional force between silica gel 7 and zigzag 9, thus move after stopping push rod 2, then body 1 slowly inserting needle is gripped, sealing vesicle 4 is still in expanded state, when sealing vesicle 4 and becoming flat suddenly, represent that syringe needle 2 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.
