Description
Technical field:
This utility model relates to medical basic nursing apparatus field, relates in particular to a kind of novel syringe.
Background technology:
Syringe often connects together with hypodermic needle, is used for liquid or gas are injected into bodily tissue or therefrom extraction, and conventional injector all is a hand held injector; So long as be made up of urceolus and center push rod, such syringe is by widespread usage, but touches the center push rod rear portion during medical personnel's one-handed performance easily; And pollute; Relatively require great effort during this mode aspiration medicinal liquid, strengthened medical personnel's working strength, and the syringe needle of syringe partly is directly to be socketed on the drain pipe through needle holder; Such syringe needle is firm inadequately with being connected of syringe body; In inhaling medicine or injection process, owing to reasons such as internal pressure are excessive, sometimes the phenomenon that syringe needle comes off can appear.
The utility model content:
The purpose of this utility model provides a kind of novel syringe, and it can avoid syringe needle to come off in inhaling medicine or injection process, the convenient and supporting use of instrumentation liquid dispenser, and safety and sanitation, good sealing effect, the scope of application is extensive.
In order to solve the existing problem of background technology, this utility model is to adopt following technical scheme: it is made up of urceolus 1, piston 2, push-pull bar 3, duct 4, position limiting structure 5, needle holder 6, drain pipe 7, external screw thread 8, syringe needle 9; Be provided with piston 2 in the urceolus 1, the front end of push-pull bar 3 is connected with piston 2, and the rear end of push-pull bar 3 is provided with and the belled duct 4 of external traction apparatus; Push-pull bar 3 is arranged on barrel one side of urceolus 1; Needle holder 6 is placed on the drain pipe 7, and drain pipe 7 is connected with the lower end of urceolus 1, and the arranged outside of drain pipe 7 has external screw thread 8; Needle holder 6 is connected through external screw thread 8 with drain pipe 7, and syringe needle 9 is connected with the lower end of drain pipe 7.
The front end of described drain pipe 7 designs for bullet, and tail end designs for cylinder.
This utility model can avoid syringe needle to come off in inhaling medicine or injection process, the convenient and supporting use of instrumentation liquid dispenser, and safety and sanitation, good sealing effect, the scope of application is extensive.
Description of drawings:
Fig. 1 is the structural representation of this utility model.
The specific embodiment:
With reference to Fig. 1, this specific embodiment adopts following technical scheme: it is made up of urceolus 1, piston 2, push-pull bar 3, duct 4, position limiting structure 5, needle holder 6, drain pipe 7, external screw thread 8, syringe needle 9; Be provided with piston 2 in the urceolus 1, the front end of push-pull bar 3 is connected with piston 2, and the rear end of push-pull bar 3 is provided with and the belled duct 4 of external traction apparatus; Push-pull bar 3 is arranged on barrel one side of urceolus 1; Needle holder 6 is placed on the drain pipe 7, and drain pipe 7 is connected with the lower end of urceolus 1, and the arranged outside of drain pipe 7 has external screw thread 8; Needle holder 6 is connected through external screw thread 8 with drain pipe 7, and syringe needle 9 is connected with the lower end of drain pipe 7.
The front end of described drain pipe 7 designs for bullet, and tail end designs for cylinder.
This specific embodiment can avoid syringe needle to come off in inhaling medicine or injection process, the convenient and supporting use of instrumentation liquid dispenser, and safety and sanitation, good sealing effect, the scope of application is extensive.
