Description
Technical field
This utility model relates to blood taking needle technical field, particularly a kind of safe blood-taking needle.
Background technology
The form of disposable blood taking needle is different, tradition blood taking needle is generally made up of syringe needle and needle handle, blood sampling site is pinned during use, extract again after thrusting rapidly skin with needle point, this mode cannot strictly control depth of needling, and in blood collection procedure, easily there is the situation of askew pin, higher to this requirement practical.
Traditional blood taking needle needs manual assembly, and efficiency of assembling is lower, and rear syringe needle of having taken a blood sample can not spring back in shell, and the syringe needle outside being exposed to easily scratches people and even used by secondary, easily causes cross infection.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of safe blood-taking needle.
For solving the problem, this utility model provides following technical scheme:
A kind of safe blood-taking needle, comprises shell, protective cap, slide block, needle body, front spring and rear spring; Described front spring and rear spring are installed on the front and rear of described needle body respectively; The described needle body being provided with front spring and rear spring is pressed in described shell by described slide block; Described slide block is provided with four for the supporting leg that leads to described needle body and two for carrying out spacing compression lower limb to described needle body; The both sides of described slide block front portion are provided with buckle; The inner side of described shell is provided with and the described draw-in groove be clasped.
Further, the medial wall of four described supporting legs is provided with the guide runner for leading to described needle body.
Further, the inner side of two described compression lower limbs is provided with the overhead kick for compressing described needle body; The sidewall of described needle body is provided with the hook matched with described overhead kick.
Further, the sloping platform for strutting described compression lower limb is provided with in described shell.
Beneficial effect: a kind of safe blood-taking needle of the present utility model, reasonable in design, is beneficial to and realizes Automated assembly, and the needle body percussion completing safe blood-taking needle is pricked after application on human skin can back stitching at once, avoid secondary to use or scratch people causing cross infection, can control depth of needling simultaneously.

Description of reference numerals: shell 1, draw-in groove 1a, sloping platform 1b, protective cap 2, slide block 3, supporting leg 3a, compresses lower limb 3b, guide runner 3d, overhead kick 3e, buckle 3f, needle body 4, hook 4a, front spring 5, rear spring 6.
Detailed description of the invention
Below in conjunction with Figure of description and embodiment, specific embodiment of the utility model is described in further detail:
Referring to figs. 1 through a kind of safe blood-taking needle shown in Fig. 5, comprise shell 1, protective cap 2, slide block 3, needle body 4, front spring 5 and rear spring 6; Front spring 5 and rear spring 6 are installed on the front and rear of needle body 4 respectively; The needle body 4 being provided with front spring 5 and rear spring 6 is pressed in shell by slide block 3; Slide block 3 is provided with four for lead to needle body 4 supporting leg 3a and two for carrying out spacing compression lower limb 3b to needle body 4; The both sides of slide block 3 front portion are provided with buckle 3f; The inner side of shell 1 is provided with the draw-in groove 1a coordinated with buckle 3f.
The medial wall of four supporting leg 3a is provided with the guide runner 3d for leading to needle body 4.
The inner side of two compression lower limb 3b is provided with the overhead kick 3e for compressing needle body 4; The sidewall of needle body 4 is provided with the hook 4a matched with overhead kick 3e.
Be provided with in shell for strutting the sloping platform 1b compressing lower limb 3b.
First remove protective cap 2 during use and just slide block 3 pressed to skin; compression lower limb 3b on slide block 3 opens to both sides along with the sloping platform 1b in shell 1; the overhead kick 3e of original stop needle body 4 removes the restriction to hook 4a on needle body 4, under the effect of rear spring 6, and needle body 4 forward slip.Front spring 5 causes compression because needle body 4 moves forward simultaneously, under the effect of the elastic force of front spring 5, makes in the shell 1 of needle body 4 retraction meeting blood taking needle.
Wherein, while the guide runner 3d on four supporting leg 3a of slide block 3 leads to needle body 4, also prevent needle body 4 from the phenomenon of askew pin occurring in percussion process.In blood collection procedure, front spring 5 controls the degree of depth that needle body 4 pricks application on human skin, and rear spring 6 provides the elastic force of trigger type.Buckle 3f on slide block 3 coordinates with the draw-in groove 1a of shell 1, can carry out spacing to the installation of slide block 3, can limit the percussion distance of slide block 3 simultaneously.
The above, it is only preferred embodiment of the present utility model, not any restriction is made to technical scope of the present utility model, therefore every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalent variations and modification, all still belong in the scope of the technical solution of the utility model.
