Anti-acupuncture type blood collection device and assembly method

Abstract

The invention provides an anti-puncture blood sampling device and an assembly method. The blood sampling device comprises a needle base, a needle sleeve and a needle support. The needle base and the needle sleeve are sleeved slidably; a blood sampling needle is fixedly connected to the head part of the needle base; the needle support and the needle base are sleeved and fixed; a first limiting bulge is arranged on the needle base; a third limiting bulge and a lock catch are arranged in an inner cavity of the needle sleeve; one end of the lock catch is fixedly connected with the needle sleeve; the other end of the lock catch is a free end; and when the needle base slides to the first limiting bulge relative to the needle sleeve so as to be clamped between the third limiting bulge and the lock catch, the blood sampling needle is covered and limited in the inner cavity of the needle sleeve. When the anti-puncture blood sampling device is assembled, the blood sampling needle, the needle base and a needle cap are connected into a whole so as to penetrate through the inner cavity of the needle sleeve through the tail part of the needle base, and finally the needle support is sleeved on the needle base. According to the anti-puncture blood sampling device and the assembly method provided by the invention, a traditional anti-puncture protection sleeve device is cancelled, and the potential safety hazard that medical personnel is punctured due to the exposure of the blood sampling needle can be effectively eliminated, so that the anti-puncture blood sampling device has the outstanding advantages of convenience, safety and reliability in use.

Description

technical field [0001] The invention relates to a blood collection device, in particular to an anti-acupuncture type blood collection device and an assembly method with its own anti-acupuncture protection function. Background technique [0002] In the production process of the existing blood collection device, it is necessary to assemble the blood collection needle and the anti-needle protection cover together, so that after the blood collection is completed, the cover of the blood collection needle can be covered by moving the anti-needle protection cover to prevent the blood collection needle from being exposed. The resulting stabbing of medical staff and other safety hazards. When the lancet is assembled with the anti-needle sheath, if the operator accidentally inserts the lancet into the anti-needle sheath, it will be difficult to withdraw the lancet from the anti-needle sheath, which will greatly affect improve assembly efficiency. If it is at the blood collection sit...

Problems solved by technology

When the lancet is assembled with the anti-needle sheath, if the operator accidentally inserts the lancet into the anti-needle sheath, it will be difficult to withdraw the lancet from the anti-needle sheath, which will greatly affect Improve assembly work efficiency

If it is at the blood collection site, before the blood collection, if the medical personnel accidentally insert the blood collection needle into the anti-needle protective cover and cannot take it out quickly, the whole set of products will not be used, which seriously affects the blood collection work efficiency
