Abstract

The invention discloses a blood collection indwelling needle, a blood collection indwelling assembly and an operation method, and the blood collection indwelling needle comprises a communication body, an inner flow channel, a needle head and a needle head, an indwelling catheter communicated with the internal flow channel; a blood sampling connecting end used for being detachably connected into a blood drainage device; and an acupuncture connecting end communicated with the internal flow channel, wherein the acupuncture connecting end is used for being detachably connected with an acupuncture device, and an indwelling needle of the acupuncture device can activate the acupuncture device when an indwelling needle tube is pulled out of the indwelling catheter, so that a needle tip is protected from being punctured by acupuncture. The blood collection connecting end is added to the blood collection indwelling needle and used for being connected with the blood drainage device. When blood sampling is carried out, secondary puncture does not need to be carried out on a patient, the pain of the patient is relieved, and meanwhile thrombosis caused by blood residues is avoided. Meanwhile, the blood sampling device can be pulled out of the communicating body after blood sampling, and the needle tube without the cutting edge cannot cause pricking injury.

Description

technical field [0001] The invention relates to a blood collection retention needle, a blood collection retention assembly and an operation method. Background technique [0002] The intravenous indwelling needle is an existing common medical device. The indwelling catheter for the IV catheter remains in the body. When the puncture needle is pulled out, it is easy to cause needle stick injury to the human body. At the same time, in the existing blood collection process, blood collection through the indwelling needle will cause blood to flow into the upper part of the hose and the infusion interface, resulting in excess blood remaining in these parts after the blood collection is completed, resulting in tube blockage. Clinical also needs to carry out second puncture blood sampling usually, has increased patient's pain. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a blood collection indwelling needle, a blood ...
