Description

Disposable urethra anesthesia medicine injecting device

Technical field

This utility model relates to a kind of anesthesia medical apparatus, and particularly a kind of disposable urethra anesthesia medicine injecting device is applicable to the treatment of operation on urethra or urethral stricture.

Background technology

When patient is carried out operation on urethra, at first to anaesthetize the urethra surface, could adopt apparatus to undergo surgery then.For the urethral stricture patient, need urethra is expanded, for alleviating the pain of bringing because of expansion, also to anaesthetize.At present to the anesthesia of urethra inner surface, the method that adopts is that anesthetics is poured in the urethra usually, or the medication cotton swab dips in the anesthetics insertion urethra gently, and the shortcoming that above method exists is: the patient suffering is big, can not carry out simultaneously with expansion; Often adopt utensils such as bonding jumper that rustless steel makes or thread metal probe for the urethral stricture patient, its weak point is: puncture mucous membrane of urethra easily, cause hemorrhage or form via, and often repeatedly use, medical cross infection easily takes place.

Summary of the invention

The disposable urethra anesthesia medicine injecting device that the purpose of this utility model is to provide a kind of patient suffering of alleviating, avoids cross infection, the expansion of shaking property of collection and even anesthesia are carried out simultaneously.

For reaching above purpose, the technical scheme that this utility model adopted is: this disposable urethra anesthesia medicine injecting device, by the expansion head, sebific duct constitutes, the expansion head is a warhead shape, smooth surface, the expansion head of this kind shape can reduce the resistance that inserts urethra, avoid damaging mucous membrane of urethra, the rear end and the sebific duct of expansion head are fixed as one, available producing once with a kind of medical grade rubber material is an integral body, the back segment hardness of expansion head and sebific duct is higher, the leading portion of sebific duct is flexible to a section of expansion head, can carry out elastic bending, to adapt to the bending of urethra, at the center of sebific duct is medicine-injecting cavity, the injection outlet is located at the end of expansion head, it is characterized in that the outside sheathed elasticity medical grade rubber film cylinder at expansion head and sebific duct, the front end of elasticity medical grade rubber film cylinder is bonded on the rear end outer wall annular table of expansion head, the rear end of elasticity medical grade rubber film cylinder is bonded on the outer wall at sebific duct middle part, gas tube on boning on the sebific duct, the inner port of gas tube is inserted in the elasticity medical grade rubber film cylinder, the external port of gas tube is connected with the elasticity gas cell, when elasticity of compression gas cell, gas in the elasticity gas cell enters in the elasticity medical grade rubber film cylinder, make elasticity medical grade rubber film cylinder rising, urethra is expanded, when unclamping the elasticity gas cell, gas in the elasticity medical grade rubber film cylinder is back to again in the elasticity gas cell, push by interruption, can realize the expansion of shaking property of urethra, overlap one deck again in the outside of elasticity medical grade rubber film cylinder and ooze the medicine elastic film, on the wall that oozes the medicine elastic film, establish medicine permeating hole, the front end that oozes the medicine elastic film is bonded on the middle part outer wall annular table of expansion head, the rear end of oozing the medicine elastic film is bonded on the rear end outer wall of elasticity medical grade rubber film cylinder, the anesthetics ascending pipe is inserted in elasticity medical grade rubber film cylinder and oozes the front side in gap between the medicine elastic film, injecting needle base is established in outer end at the anesthetics ascending pipe, when using this utility model, under the guiding of expansion head, insert in the urethra gradually, in the insertion process, can be by shaking property elasticity of compression gas cell, to the expansion of shaking property of urethra, again by injecting anesthetics, anesthetics can ooze out from medicine permeating hole, the urethra inner surface is anaesthetized, if need injection therapeutic medicine, can from the medicine-injecting cavity of sebific duct, inject.This utility model is also implemented by following measure: medicine permeating hole can reticulate arrangement, and the aperture is 1mm because the outer wall of elasticity medical grade rubber film cylinder presses close to the inwall that oozes the medicine elastic film, so the anesthetics flow velocity is slow, ooze powder long-pending big, even, anaesthetic effect is good; Fix the injection needle stand in the rear end of sebific duct, when the needs drug-injection in treatment, available syringe is inserted in and carries out drug-injection in treatment on the injection needle stand; In the outer wall of sebific duct, also bury a tractive steel wire underground, the front end of tractive steel wire is fixed on the aft bulkhead of expansion head, stretch out in the wall of sebific duct rear end the rear end of tractive steel wire, by pulling tractive steel wire, can make sebific duct leading portion rubber-like carry out bending for one section, to adapt to different patients' urethra bending.

The beneficial effects of the utility model are: simple in structure, cost of manufacture is low, can disposablely use, simultaneously, because collection expansion, anesthesia, dispenser treatment are carried out simultaneously, and can carry out appropriateness adjustment according to the bending of patient's urethra, so easy to use, in operating process, can alleviate patient's misery.
