Description
Technical field
This utility model relates to a kind of venipuncture needle, belongs to technical field of medical instruments.
Background technology
At medical field; infuse to patient or blood drawing etc. all will use venipuncture needle; existing venipuncture needle is all disposable; used and once will be lost; then waste disposal is taken as; the syringe needle of puncture needle is without any protector; after medical worker to carry out for patient with venipuncture infusing or draw blood; probably cause exposed syringe needle medical worker to be stabbed thus caused by mistake to catch; can threaten to the personal safety of medical worker; and when carrying out waste disposal, also same threat may be caused to relevant staff.
Utility model content
Based on above weak point, the technical problems to be solved in the utility model is to provide a kind of venipuncture needle, its can after puncture needle uses by Tip protection in protective sleeve, prevent it from accidentally injuring other staff personal safety to other staff and work the mischief.
For solving above technical problem, this utility model have employed following technical scheme:
A kind of venipuncture needle; comprise draw point seat and be installed on the draw point on draw point seat; also comprise spring and the protective sleeve sheathed with draw point; described spring one end is fixed on described draw point seat; the other end is fixed on described protective sleeve; be provided with the force-applied holder passed of draw point in described protective sleeve, the needle point of described draw point is positioned at described protective sleeve inside when described spring is in straight condition.
Further, described holder is provided with fixing draw point and the pin hole passed for described draw point, coordinating between described draw point with described pin hole is interference fit.
Further, described holder is made by being easy to the material that puncture of steel needles passes through.
Further, the material of described holder is flexible plastic or rubber.
Further, also adsorber is provided with in described protective sleeve.
Further, described adsorber is sponge or cotton balls.
Further, the material of described spring is plastics or memory metal.
Further, described draw point seat is provided with the fin for gripping.
Adopt above technical scheme, the beneficial effect acquired by this utility model is:
This utility model provides a kind of venipuncture needle, and syringe needle can be limited in protective sleeve by it after puncture needle uses, and prevents it from accidentally injuring other staff personal safety to other staff and works the mischief, and can by syringe needle with blood sop up.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, technology of the present utility model is described in further detail:
Fig. 1 is the structure chart of the embodiment 1 of this utility model venipuncture needle;
Fig. 2 is the structure chart of the embodiment 2 of this utility model venipuncture needle.
Detailed description of the invention
Embodiment 1
As shown in Figure 1; this utility model provides a kind of venipuncture needle; the draw point 2 comprising draw point seat 1 and be installed on draw point seat 1; also comprise spring 3 and the protective sleeve 4 sheathed with draw point 2; spring 3 one end is fixed on draw point seat 1; the other end is fixed on protective sleeve 4, is provided with the force-applied holder 41 passed of draw point in protective sleeve 4, and the needle point of draw point 2 is positioned at protective sleeve 4 inside when described spring 3 is in straight condition.Applying power to draw point 2 can make draw point 2 through holder 41; to puncture to vein, puncture complete, the needle point of draw point is exited holder 41; the needle point of draw point is positioned at protective sleeve 4 inside, prevents it from accidentally injuring other staff's personal safety to other staff and works the mischief.
Wherein, holder 41 is made by being easy to the material that draw point 2 spikes through, such as holder 41 is made up of the material such as plastics or rubber, when not having external force or external force very little, draw point 2 can not pass holder 41, is applying certain active force to draw point 2, draw point 2 can spike through holder 41, when draw point 2 is released holder 41, due to the elasticity of material, on holder 41, perforated position can restore to the original state again.
Wherein, be also provided with adsorber 42 in protective sleeve 4, adsorber 42 is sponge or cotton balls, and the blood on needle point 21 can sop up by adsorber 42, and is easy to wear out.
Wherein, accommodation space 43 is also provided with in protective sleeve 4; accommodation space 43 is positioned at the rear portion of protective sleeve 4; protection is provided further to needle point 21; when needle point 21 is return from holder 41 and adsorber 42; the needle point 21 of draw point 2 is positioned at accommodation space 43, is not easy pass adsorber 42 again and pass from holder 41.
Wherein, the material of spring 3 is plastics or memory metal.
Wherein, draw point seat 1 is also provided with the fin 11 for gripping.
Wherein, spring 3 is set on draw point 2, as shown in Figure 1.Spring also can be arranged on the side of draw point 2.
When using this utility model venipuncture needle; one holds protective sleeve 4; another holds fin 11 and firmly the needle point 21 of draw point 2 is released holder 41; penetrate vein; after finishing using; the needle point 21 of draw point 2 is return holder 41 gently; by adsorber 42, the blood on the needle point 21 of draw point 2 is sopped up; needle point 21 is positioned at protective sleeve 4; draw point 2 can not be deviate from from protective sleeve 4; and draw point 2 is not easy again pass adsorber 42 and pass from holder 41, can prevent draw point 2 from other staff being stabbed, and cause other people to catch by mistake.
Embodiment 2
As shown in Figure 2, from the difference of embodiment 1, embodiment 2 is only that the structure of holder 41 is different: holder 41 is provided with fixing draw point 2 and the pin hole 411 passed for described draw point 2, coordinating between draw point 2 with pin hole 411 is interference fit, holder 41 is made for elastomeric material such as plastics or rubber, can draw point 2 be clamped fixing before venipuncture needle uses, draw point 2 when exerting oneself to draw point 2 in use, can be made mobile in holder 41.
Last it is noted that these are only preferred embodiment of the present utility model; be not limited to this utility model; although be described in detail this utility model with reference to embodiment; for a person skilled in the art; it still can be modified to the technical scheme described in foregoing embodiments; or equivalent replacement is carried out to wherein portion of techniques feature; but it is all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
