Description
Technical field
This utility model relates to medical instruments field, particularly relates to a kind of blood taking needle.
Background technology
A kind of in medical inspection process for the blood taking needle of blood sample collection, be made up of syringe needle and shank, syringe needle is located at the head of shank, and shank slidably connects sheath, is provided with back-moving spring and the initial position of sheath is positioned at the head of syringe needle and shank between sheath and shank.When blood taking needle head presses on limbs of patient by the hand-held needle tubing of operator, sheath indentation under the elastic force effect of skin, syringe needle being protruded and thrusts skin to cause Wicresoft, when pulling out again to reset under the effect of sheath at back-moving spring after blood taking needle syringe needle being covered to avoid syringe needle to expose contaminated or accidental puncture human body.When blood taking needle is pulled out, needle tubing and cavity that skin encloses increase gradually, form instantaneous negative pressure, are conducive to the collection of blood sample.Vacuum blood collector is made up of vacuum test tube, blood taking needle, needle holder three parts.Vacuum test tube is its key component, is mainly used in collection and the preservation of blood preparation.Vacuum test tube is prefixed a certain amount of negative pressure in process of production, and when after blood taking needle puncture intravasation, due to the suction function in blood taking tube, blood flows in blood taking tube automatically; Meanwhile, in blood taking tube, be prefixed various additive, clinical multinomial comprehensive blood testing can be met completely.
Utility model content
This utility model, in order to overcome deficiency of the prior art, provides and a kind ofly guarantees that needle point direction is consistent and can avoid the disposable blood taking needle of cross infection in blood collection procedure.
This utility model is achieved through the following technical solutions:
A kind of blood taking needle, comprise syringe, syringe needle and needle stand, described syringe needle is fixed in needle stand, needle stand is fixed together by locking nut and syringe, and described needle tip is connected with head protector, is characterized in that described syringe inside is provided with the passage equal with syringe bottom height, syringe external wall of upper portion is provided with anti-slip veins, syringe bottom outer wall is sleeved in the test tube with piston, and syringe passes through together with piston slipper seal with test tube, and test tube top is provided with handle.
Described head protector is can breakaway-element needle protection cap.Described syringe needle is rustless steel syringe needle.Described needle tip is connected with can breakaway-element needle protection cap, and can pull off by breakaway-element needle protection cap with hands, syringe needle just can expose; Once can be disconnected by breakaway-element needle protection cap, this blood taking needle is not reproducible utilization just.
Compared with prior art, the beneficial effects of the utility model are: this utility model provides a kind ofly to be guaranteed that needle point direction is consistent and can avoid the disposable blood taking needle of cross infection in blood collection procedure.
