Abstract
The utility model discloses a disposable injector and belongs to medical devices. The disposable injector comprises an outer sleeve, a piston, a core bar and an injection needle. The piston is sleeved at one end of the core bar, and the core bar where the piston is installed is sleeved in the outer sleeve. The disposable injector is characterized in that a clamping groove for fixing the injection needle is arranged in a long axis direction of a turned edge of the outer sleeve. According to the technical scheme, the injection needle is clamped in the clamping groove positioned on the turned edge of the outer sleeve, the position of a needle head is fixed, so that safety of the injection needle can be guaranteed, the problem that the injection needle is damaged and polluted due to the fact that the injection needle falls to the ground in the conveying process or in the package dismantling process is solved, the clamping groove is positioned on the turned edge of the outer sleeve and can add contact points for fingers, and medical workers can use the disposable injector conveniently and smoothly.
Description
Technical field
This utility model belongs to medical mechanical domain, specifically be disposable syringe.
Background technology
Disposable syringe is the medical apparatus and instruments of using always, and it includes overcoat, piston, core bar, entry needle.Generally speaking, entry needle has three kinds of assemble methods: 1. entry needle is directly connected with outer taper, 2. entry needle does not connect with outer taper and directly puts into packaging bag, 3. entry needle is put into the space of core bar and overcoat.These three kinds of assemble methods can't avoid syringe in transportation, to cause fractureing or medical personnel when the dress of unpacking uses entry needle because landing damage, the pollution that causes.
Summary of the invention
Technical problem to be solved in the utility model is that fracture and/or the unpack dress use worker of entry needle in transportation of disposable syringe damages, pollutes.
The technical scheme in the invention for solving the above technical problem is: disposable syringe, include overcoat, piston, core bar, entry needle, piston bush is contained in an end of core bar, the core bar that piston is housed is sleeved in the overcoat, it is characterized in that described overcoat crimping long axis direction is provided with the fixedly draw-in groove of entry needle.
The nearly core bar end of described draw-in groove is circular-arc, and arc diameter is less than entry needle cover top diameter.
Described draw-in groove is one or two.
Adopt technique scheme, entry needle is stuck in the draw-in groove on the overcoat crimping, needle position is fixed, can guarantee the safety of entry needle like this, make entry needle and can not damage, pollute on the ground because dropping in transportation or in the dress of unpacking, and having draw-in groove can increase the contact point of finger on the overcoat crimping, medical personnel use smoothly more convenient.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is vertical view of the present utility model;
1 overcoat among the figure, 11 overcoat crimpings, 12 draw-in grooves, 2 pistons, 3 core bars, 4. entry needle, 5 injection needle guards.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As can be seen from Figure 1, disposable syringe includes overcoat 1, piston 2, core bar 3, entry needle 4, piston 2 is sleeved on an end of core bar 3, the core bar 3 that piston 2 is housed is sleeved in the overcoat 1, it is characterized in that, described overcoat crimping 11 long axis directions are provided with the fixedly draw-in groove 12 of entry needle.Draw-in groove 12 nearly core bar 3 ends are circular-arc as shown in Figure 2, and arc diameter is less than injection needle guard 5 upper diameter.
Claims (3)
