Embodiment

[0025] like Figure 1 to Figure 5 As shown, the mechanism dedicated to protecting the venous blood collection needle, in actual use, its function object is the venous blood collection needle, and the venous blood collection needle part is the same as the structure commonly used now. Cover 3, needle handle 6, hose 7 and puncture bottle stopper end (not shown on the figure), this scheme increases on the traditional structure: needle handle clip 5, return protection cap 1, non-return cap 4 and These several main structures of the soft adsorption material (not drawn on the figure) of the protective cap front end. The added structure is formed by injection molding, and is sequentially fastened to the needle handle through slots and concave-convex platforms. The return protection cap 1 is a cylindrical structure with a hollow interior and openings at both ends. The cavity of the return protection cap 1 is named the return protection cap cavity 1-2, and a soft adsorption material is...

Abstract

The invention discloses a mechanism specially used for protecting venous blood collection needles, which comprises a protective cap which is hollow inside and has openings at both ends. A non-return cap is arranged under the protection cap, and the bottom end of the return protection cap is inserted into the non-return cap. The invention is easy to operate, does not change the main structure, does not need to consider complex operation instructions, wrong use, special usage habits and other issues before use; does not change the operating habits after use, this simple design that does not change the operating habits can be completely replaced At present, ordinary venous blood collection needles have wide application; the structure is simple, the added parts are clamped on the blade of the needle handle, and the main structure of the venous blood collection needle does not change, the risk is the lowest, and it is easy to realize safe protection in clinic. The adsorption material at the front end absorbs the remaining blood after the needle is pulled out to achieve complete protection; before use, it does not touch the internal structure of the blood collection needle at all, and does not increase the compatibility and toxicity risks of the device and the blood collection needle.

Description

technical field [0001] The invention relates to a medical device, in particular to a mechanism specially used for protecting venous blood collection needles. Background technique [0002] Blood collection needles are disposable medical consumables in the medical field. Among them, the venous blood collection needle with flexible tube is widely used in clinical departments because of its advantages such as easy to hold when the needle handle blade is operated, easy to observe the blood return through the flexible tube, and easy to puncture and pull out the blood collection tube at the distal end of the puncture bottle. [0003] The management regulations of medical institutions require blood collection operators to protect the puncture needle tip after completing the blood collection operation to prevent the risk of re-stab injury and blood source contamination. The traditional method is: put the plastic sheath of the blood collection needle back on the cover, this operation...
