Description

Technical Field

[0001] This invention relates to the field of blood collection needle technology, and more particularly to a safe blood collection needle. Background Technology

[0002] Currently, in the medical field, medical staff collect and obtain human physiological and pathological information through various means to accurately diagnose diseases. Among them, blood samples are usually collected through the following three methods: subcutaneous blood collection, which is mostly used for simple classification and counting of blood components and usually uses the body of a subcutaneous (solid or triangular) blood collection needle; and venous blood collection, which can be used for detailed testing of hematological, blood pathogenic and other related indicators.

[0003] However, existing blood collection needles have the following drawbacks:

[0004] (1) Most of the intravenous blood collection needles used in clinical practice are ordinary blood collection needles. When collecting blood, the protective cap on the needle is removed. After the blood collection is completed, due to the lack of protective measures for the blood collection needle, the blood collection needle is easily injured by external impact, causing personal injury to the patient or medical worker. Utility Model Content

[0005] In order to solve one or more technical problems existing in the prior art, the purpose of this application is to provide a safe blood collection needle to avoid injury to patients or medical workers caused by external impacts to the blood collection needle body.

[0006] To address the aforementioned technical problems, one of the objectives of this application is achieved through the following technical solution:

[0007] A safe blood collection needle includes a tube, a connecting tube fixedly disposed on the right side wall of the tube, a needle disposed on the right side wall of the connecting tube, a protective cap inserted into the right end of the connecting tube and capable of covering the needle, and a protective component. The protective component protects the needle, and the protective cap can be removed from the needle to protect the needle.

[0008] Furthermore, the protective component includes a sleeve plate, an insertion hole on the sleeve plate, a connecting plate connected to the sleeve plate, a support plate connected to the connecting plate, and two side plates connected to the support plate. The support plate and the two side plates surround each other. The protective component is sleeved on the connecting pipe through the insertion hole, and the connecting pipe can be snapped between the support plate and the two side plates.

[0009] Furthermore, the protective component includes a fixed sleeve fixedly fitted onto the connecting tube and a protective sleeve that is slidably connected between the fixed sleeve and the connecting tube, the protective sleeve being able to cover the needle tip.

[0010] Furthermore, a sliding groove is provided at the top of the fixed cylinder, and a sliding rod that is fixedly connected to the protective cylinder is slidably provided in the sliding cylinder.

[0011] Furthermore, a limiting component for limiting the protective cylinder is fixedly provided on the fixed cylinder. The limiting component includes a fixed shell fixedly disposed on the top of the fixed cylinder, a slot opened on the protective cylinder and corresponding to the fixed shell, a pin rod disposed between the fixed shell and the fixed cylinder and capable of being inserted into the slot, a stop rod located inside the fixed shell and fixedly connected to the pin rod, and a limiting spring disposed between the stop rod and the fixed shell and sleeved on the pin rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] (1) When in use, after the protective cap is removed from the needle, the needle can be protected by setting a protective component to prevent the blood collection needle body from being injured by external impact. Compared with the existing technology, it solves the technical problem that after blood collection is completed, due to the lack of protective measures for the blood collection needle, the blood collection needle is easy to injure patients or medical workers by external impact, causing personal injury.
