Abstract
The utility model discloses an injector for intramuscular injection. The injector for intramuscular injection comprises an entry needle, a needle tube, a piston and a push rod. The entry needle is connected with the needle tube. The piston is located in the inner portion of the needle tube. The push rod is connected with the back portion of the piston. A needle guard covers the needle tube. The needle guard is tube-shaped. The inner wall of the back portion of the needle guard is provided with a bulge loop. The front end of the needle tube is provided with the bulge loop. The injector for the intramuscular injection is characterized in that the structure is simple and the needle guard can not influence the use of injector. After the injection is finished, the needle guard is pushed to cover the entry needle. The puncture and infection of persons concerned are avoided.
Description
Technical field
This utility model medical apparatus and instruments relates in particular to the syringe for intramuscular injection.
Background technology
The syringe that intramuscular injection is used is by entry needle, needle tubing, piston, push rod consists of, entry needle connects needle tubing, piston is arranged in syringe intracavity, the piston rear portion connects push rod, usually is furnished with sheath on the entry needle, entry needle is installed on the needle tubing during use, take off sheath imbitition injection, but after intramuscular injection was finished and taken out syringe, because sheath is too little, sheath was not easy again to be set on the entry needle, for preventing that being injected device stabs the cross infection that occurs, the movement of syringe needs SC, however, still has medical personnel accidentally to stab and carries out loaded down with trivial details epidemic prevention and process.
Summary of the invention
The purpose of this utility model provides a kind of syringe that entry needle can be hidden after intramuscular injection is finished.
Syringe of the present utility model is made of entry needle, needle tubing, piston, push rod, and entry needle connects needle tubing, and piston is arranged in syringe intracavity, the piston rear portion connects push rod, and needle guard, this needle guard are arranged is cylindrical body to cover on the needle tubing, on the inwall of needle guard rearward end bulge loop is arranged, the needle tubing leading section has bulge loop.
Can also there be projection at the bulge loop rear portion of needle tubing, and the bulge loop on the needle guard inwall can be accommodated in the interval between projection and the bulge loop.
This utility model simple structure, needle guard can not affect the normal use of syringe, after intramuscular injection is finished, promote needle guard, and needle guard contains entry needle in needle guard to front slide, avoid stabbing the relevant personnel and cause infection.
Description of drawings
Fig. 1 is a kind of embodiment sketch map of this utility model.
The specific embodiment
Syringe as shown in the figure is made of entry needle 1, needle tubing 2, piston 3, push rod 4, entry needle 1 connects needle tubing 2, piston 3 is arranged in the inner chamber of needle tubing 2, piston 3 rear portions connect push rod 4, rear push pedal 5 is arranged at push rod 4 rear portions so that the finger push push rod, the rear portion of needle tubing 2 radially is extended with baffle plate 6, so that point grip needle cannula 2 and produce counteracting force when the finger push push rod, medicinal liquid steadily is advanced in the muscle.
The outer cover of needle tubing 2 has needle guard 8, needle guard 8 is cylindrical body, on the inwall of needle guard 8 rearward end bulge loop 9 is arranged, needle tubing 2 leading sections have bulge loop 10, at syringe after intramuscular injection is finished, promote needle guard 8, needle guard 8 prevents that to front slide until the bulge loop 9 of needle guard 8 rearward end is stuck in the bulge loop 10 of needle tubing 2 leading sections needle guard 8 from coming off.The length of needle guard 8 is consistent with needle tubing 2 length, and when needle guard 8 was shifted needle tubing 2 front portion onto, needle guard 8 can entangle entry needle 1 fully, thus entry needle 1 is hidden in the needle guard 8, avoids the generation of the accident of stabbing.
There is projection 11 at the bulge loop rear portion of needle tubing 2, and the bulge loop 9 on needle guard 8 inwalls can be accommodated in the interval between projection 11 and the bulge loop 10, is fixed in the needle tubing front portion after needle guard 8 is released.
Claims (2)
1. syringe that is used for intramuscular injection, consisted of by entry needle, needle tubing, piston, push rod, entry needle connects needle tubing, piston is arranged in syringe intracavity, and the piston rear portion connects push rod, it is characterized in that, cover has needle guard on the needle tubing, this needle guard is cylindrical body, on the inwall of needle guard rearward end bulge loop is arranged, and the needle tubing leading section has bulge loop.
2. described scraps of paper waste discharge apparatus according to claim 1 is characterized in that there is projection at the bulge loop rear portion of described needle tubing, and the bulge loop on the needle guard inwall can be accommodated in the interval between projection and the bulge loop.
