Description
Technical field
This utility model belongs to medical blood taking instrument technical field, is specifically related to a kind of safe blood-taking needle.
Background technology
Often need blood sample collection during blood test, mode comparatively conventional is at present disposable blood taking needle, and disposable blood taking needle is convenient, fast.Patent 200920241449.1 discloses disposable front some triggered safety self-destruction blood taking device.The clamping wall of this blood-taking device and tail-hood are vertically disposed, the pressure that clamping device is easily subject to spring and needle stand causes also not using, transmitting of losing efficacy, recess on clamping wall is also adopt vertical structure, and during use, extruding struts required power comparatively greatly, causes patient to use and feels uncomfortable; The plug pushing away hair device be cylindrical, corresponding block supporting be cylindrical channel, when extracting block before using, plug is taken out of by syringe needle and is retained in tract, does not use, loses efficacy.
Utility model content
This utility model, for the defect of prior art, proposes a kind of safe blood-taking needle.
A kind of safe blood-taking needle; the bottom of shell 1 is provided with tail-hood 2; tail-hood 2 is connected with base 3; base 3 is provided with clamping limb 4; described clamping limb 4 is arranged in 70-90 ° of angle with described base 3; the inner side of described clamping limb 4 is provided with recess 17; spring 5 is provided with in the middle of described clamping limb 4; spring 5 is connected with fixed block 6; be provided with blood taking needle 7 in the middle part of described fixed block 6, the bottom of described fixed block 6 is provided with two elastic clips 8, and the top of described blood taking needle 7 is provided with fungi-proofing interior plug 9; the end of described shell 1 is provided with and pushes away hair device 10, described in push away hair device 10 outside and be provided with protective cap 11.
Recess 17 cross sectional shape of described clamping limb 4 is rectangle or trapezoidal.
The passage 13 that described protective cap 11 is provided with plug 12 and coordinates with plug 12.
Described plug 12 is provided with annular protrusion 14, and the groove 15 be equipped with.
The shape of described housing 1 is cuboid.
The described hair device 10 that pushes away is provided with guiding wall 16.
The beneficial effects of the utility model: the blood taking needle clamping limb of this utility model pin adopts the structure of indent, power used when making to extrude is less, and the inwall of clamping limb is provided with indent thin-walled, and the dynamics that struts needed for making is less, and elasticity increases comfort more by force; Push away hair device and be provided with the guiding wall preventing needle stand from deflecting, to be gone directly blood sampling site by tract smoothly when ensureing that needle stand is launched; Push away hair device and be provided with annular protrusion and supporting groove, plug is firmly engaged by stopping means with safety protection cap.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described further.
Embodiment 1
A kind of safe blood-taking needle, as Figure 1-3, the bottom of shell 1 is provided with tail-hood 2, tail-hood 2 is connected with base 3, base 3 is provided with clamping limb 4, described clamping limb 4 is arranged in 70-90 ° of angle with described base 3, the inner side of described clamping limb 4 is provided with recess 17, spring 5 is provided with in the middle of described clamping limb 4, spring 5 is connected with fixed block 6, blood taking needle 7 is provided with in the middle part of described fixed block 6, the bottom of described fixed block 6 is provided with two elastic clips 8, the top of described blood taking needle 7 is provided with fungi-proofing interior plug 9, the end of described shell 1 is provided with and pushes away hair device 10, described hair device 10 outside that pushes away is provided with protective cap 11.
Conventional clamping limb is easily subject to spring and needle stand pressure causes also not using, and launches inefficacy, and clamping limb of the present utility model is provided with inside angle and forms strengthening gmatjpdumamics, thus needle stand is firmly limited, and can not cause using front inefficacy by external force.
Recess 17 cross sectional shape of described clamping limb 4 is rectangle or trapezoidal.Conventional clamping limb extrudes that to strut required power comparatively large in use, and cause doctors and patients' use sense by uncomfortable, clamping limb of the present utility model is provided with recess, wall is thin make needed for the dynamics that struts less, elasticity is stronger, increases comfort.
The passage 13 that described protective cap 11 is provided with plug 12 and coordinates with plug 12.
Described plug 12 is provided with annular protrusion 14, and the groove 15 be equipped with.The groove of annular protrusion and cooperation thereof is firmly engaged by stopping means.
The shape of described housing 1 is cuboid.
As shown in Figure 4, push away hair device 10 described in and be provided with guiding wall 16.To be gone directly blood sampling site by tract smoothly when guiding wall to ensure that needle stand is launched, and the hair device that pushes away of routine guides wall without this, when very easily causing launching, needle stand front end is arranged on the wedge edge barrier that pushes away hair device front end and is stuck in accent and cannot penetrates, thus blood sampling was lost efficacy.
The embodiment of the above is only preferred embodiment of the present utility model, not limits practical range of the present utility model with this, therefore the equivalence change that all shapes according to this utility model, structure and principle are done, all should be covered by protection domain of the present utility model.
