Abstract
The utility model belongs to the technical field of medical equipment equipment technique and specifically relates to a modified syringe is related to. An anti -pollution medical syringe, includes cylinder (1) and piston (2), characterized by still includes: piston protective sheath (3), press cap (4), piston protective sheath (3) are fixed connection and are in the cylindrical section of thick bamboo of the inner wall of cylinder (1), piston protective sheath (3) are equipped with spout (5), according to cap (4) for passing spout (5) with piston (2) fixed connection, and can drive the outside outstanding block that removed along spout (5) piston (2). The utility model discloses the hand pollutes the syringe when preventing to operate, has avoided doctor source sexuality to dye, and simple structure uses safe and reliable, convenient operation.
Description
Technical field
This utility model relates to medical device equipment technical field, especially relates to a kind of syringe of improvement.
Background technology
Syringe is apparatus conventional in medical treatment, and current common infusions device comprises syringe, piston, and when sterile working requires to inhale medicine, finger can only hold the handle of piston outermost end.In real work, because handle and piston are an overall structure, directly connect, when making up a prescription and inject, point often contact piston and cause pollution.Particularly when making up a prescription, because dispensing injector with pin range is large, piston twitches distance, nursing work load is large, though the nurse that makes up a prescription has aseptic concept when completing dosing program fast, easier finger gripping is inadvertently to piston, cause antibacterial to enter in medicine, cause nosocomial infection.Find that the size that the contaminated chance of medicine twitches number of times and hands contact piston area back and forth with piston obviously increases after deliberation, medicine invades patient's body with liquid, and increasing the chance infected, is the key factor of nosocomial infection.
Utility model content
The purpose of this utility model is: provide a kind of antipollution injector for medical purpose.
The technical solution of the utility model is:
An injector for medical purpose for resist printing, comprises syringe and piston, it is characterized in that also comprising: piston protective sleeve, by cap;
Described piston protective sleeve is the cylindrical tube be fixedly connected with described syringe, is provided with chute;
Described chute is be located at the oblong openings on described piston protective sleeve sidewall;
Described is to be fixedly connected with described piston through described chute and described piston can be driven along the outwardly block of chute movement by cap.
Further, the length of described chute is equal to or greater than the length of described syringe.
Further, the front end face of described piston is piston nose face, described be in by cap or less than described chute foremost time, described piston nose face is just in time at the minimum scale line of described syringe; Slide into by cap the maximum scale line that described piston nose face is in described syringe described in described chute can make.
Further, described is be easy to the hemispherical that human finger stirs by cap, and the connector being provided with cuboid is fixedly connected with described piston.
Further, described piston protective sleeve is the structure that is one of the forming with described syringe.
Further, described piston protective sleeve is for be fixedly connected with by threaded engagement with described syringe.
Using method of the present invention: when drawing medicinal liquid, move forward to by chute described in shade described in making by cap described in pulling and make described piston move forward to the minimum range of described syringe along described syringe inwall, described syringe aims at medicinal liquid; Pull and described make describedly to move backward by chute described in shade by cap, make described piston start to draw medicinal liquid, until required range along the drive of moving backward of described syringe inwall.During liquid medicine injection, move forward to by chute described in shade described in making by cap described in pulling and described piston is travelled forward along described syringe inwall, medicinal liquid is injected.In operation, piston all the time can not be contaminated.
When this utility model prevents from operating, hand contamination is to syringe, avoids nosocomial infection, and structure is simple, safe and reliable, easy to operate.
