Description

Technical Field

[0001] The utility model belongs to the technical field of blood collection needles, and in particular relates to a puncture-proof blood collection needle which is easy to fix. Background Art

[0002] A lancet is an instrument used to collect blood samples during medical examinations. It consists of a needle and a needle rod, and a sheath is provided at the existing needle position to prevent the needle from stabbing the hands of medical staff, facilitate the insertion of the needle into the patient's vein, and facilitate the subsequent disposal of the lancet.

[0003] In the Chinese patent with the publication number CN219982895U, a puncture-proof blood collection needle that is easy to fix is ​​mentioned, which includes a storage seat and a needle body. The storage seat includes a storage tube, a handle and an elastic member. The handle is arranged on the outer wall of the storage tube, and the elastic member is arranged in the storage tube. The handle and the elastic member are both located at the right end of the storage tube. The needle body includes a needle tube and a needle. The needle tube is movably arranged in the storage tube and can be locked by the handle. The needle head is arranged at the right end of the needle tube and passes through the right end of the storage tube. When the handle releases the lock on the needle tube, the elastic member drives the needle tube to move leftward along the storage tube so that the needle head shrinks from the outside of the storage tube to the storage tube part. According to the puncture-proof blood collection needle that is easy to fix provided by the utility model, the needle head can be hidden, so as to prevent the needle head from being exposed to the outside and accidentally stabbing medical staff. At the same time, it is convenient to fix it on the patient's skin when drawing blood to prevent the needle head from slipping off.

[0004] However, the above technical solution places the blood collection needle in the storage tube by extending and retracting the blood collection needle in the storage tube. However, after the device is extended from the storage tube, the needle is easily shaken when inserted into the patient's vein, causing the needle to affect venous blood drawing, so the staff needs to improve it.
