Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a safe blood collection needle. Background Art

[0002] The blood collection needle is a medical product, mainly used to collect human blood samples quickly and accurately. It has the characteristics of exquisite design, simple operation and convenient use. It is an indispensable tool for blood stations, blood collection points and laboratories.

[0003] The existing blood collection needle is provided with a detachable protective cover on the outside. Before use, the protective cover is removed before blood collection. The inner hole of the protective cover is thinner due to the thin needle. It is inconvenient to put it back on the needle, and there is a risk of stabbing the operator. When it is directly thrown into a medical waste bag or a sharps box, there is also a risk of stabbing medical staff because the needle is directly exposed. Utility Model Content

[0004] The purpose of the utility model is to overcome the above problems and provide a safe blood collection needle. To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A safe blood collection needle, comprising a needle handle and a needle head, wherein the needle head is arranged at the front end of the needle handle, a wing plate is arranged on one side of the needle handle, and a rotating block rotating around the needle handle is arranged on the side of the wing plate away from the needle head;

[0006] The needle handle and the needle head are provided with a protective cover, one side of the protective cover is provided with a slot, and both ends of the protective cover are provided with grooves matching with the clamping block on the side away from the slot;

[0007] The protective sleeve is sleeved on the needle handle and the needle head, and the slot cooperates with the wing plate, so that the protective sleeve slides along the wing plate and the rotating clamping block is clamped in the groove.

[0008] As an improvement, the needle handle is provided with an annular groove on one side of the wing plate, and the rotating clamping block includes a clamping portion and a sleeve ring matched with the annular groove.

[0009] As an improvement, a blood sampling channel is provided at the end of the needle handle.

[0010] As an improvement, the protective cover is made of medical PVC or PE material.

[0011] The advantages of the utility model are:

[0012] The utility model fixes the protective cover by clamping the protective cover with the needle handle and the needle. Before the blood collection needle is used, the protective cover does not need to be removed, but is pulled behind the wing plate. Therefore, when the operation is completed, the protective cover can be pushed forward directly to complete the operation of completely covering the needle with the protective cover.

[0013] The utility model has a simple and reasonable structure and is easy to operate, and can effectively put the needle into the protective cover before and after use, thereby avoiding the potential risk of puncture caused by the exposed needle. BRIEF DESCRIPTION OF THE DRAWINGS
