Description

technical field

[0001] The invention relates to the field of medical equipment, in particular to a multifunctional blood collection device for laboratory. Background technique

[0002] A lancet is a device used to collect blood samples during medical testing for sampling venous or arterial blood.

[0003] Chinese patent CN205094453U discloses a blood collection needle, which includes a needle head, a needle handle, a connecting tube, a blood collection tube plug puncture head and a protective cap, and the protective cap is sleeved on the outer wall of the needle head.

[0004] At present, the commonly used disposable blood collection needle needs to be covered with a protective cover to protect the needle before use, for example to prevent the needle from being bent or collided. When in use, pull out the protective cover, which is likely to cause the risk of stabbing, but the real danger lies in the disposal stage after the blood collection is completed. Needle covers are ...

Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] Such as Figure 1-7 As shown, a multifunctional blood collection device for laboratories includes a blood collection needle 1, a catheter 2, and a blood collection tube plug puncture head 3 connected in sequence to realize blood collection and delivery. One side of the blood collection needle 1 is fixedly connected with a needle handle 4 , and a plastic hose 5 is sheathed on the blood collection needle 1 . The blood collection tube plug puncture head 3 includes a cylindrical needle tube 6 and a puncture needle 7 arranged on the needle tube 6. The outer wall of the needle tube 6 is provided with a storage tube 8 arranged along its length direction. The diameter of the inner wall of the storage tube 8 is larger than that of the plastic hose 5. The diameter of the outer wall is used for embedding of the plastic hose 5 or the blood collection needle 1 , a...
