Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an intelligent blood sampling pulse meter. Background Art

[0002] At present, blood tests are routinely performed on patients in hospitals at all levels. The general operation process is: the patient goes to the designated blood drawing station in the hospital, the nurse ties a tourniquet on the patient's upper arm to prevent the venous blood from flowing back into the upper arm, and then punctures the appropriate surface vein to draw blood. After the blood drawing is completed, the nurse removes the rubber tourniquet and sends it to the disinfection center for disinfection before reuse.

[0003] However, the use of latex tube compression cuffs is unsafe. Long-term disinfection and repeated use will cause their elasticity to deteriorate and they will easily break, affecting the use effect. There is a risk of blood reflux during blood collection. In addition, operators are prone to forget to loosen them after use, which can cause limb blood circulation disorders in patients. For special patients with limited mobility, since they cannot perceive limb discomfort for a long time, severe cases may result in amputation.

[0004] In view of the above reasons, the utility model proposes an intelligent blood sampling and pulse measuring device to solve the above technical problems. Utility Model Content
