Description

Technical Field

[0001] The invention relates to the technical field of nursing hemostasis, in particular to a nursing hemostasis device and a hemostasis method for hemodialysis. Background Art

[0002] Whether it is during surgery or in daily trauma management, disease treatment and other scenarios, effective hemostasis is indispensable. Especially during dialysis, it is necessary to establish vascular access, such as arteriovenous fistula, to ensure sufficient blood flow. However, after each dialysis, hemostasis at the puncture site becomes a key issue.

[0003] Some existing hemostatic devices use overall compression to achieve hemostasis. Such devices usually try to prevent blood from flowing out by applying uniform pressure to the entire wound area. The overall compression method lacks specificity. The distribution of blood vessels and physiological structures in different parts of the human body vary greatly, and the conditions of wounds are also different. Some wounds may only be local small blood vessels ruptured and bleeding. Overall compression will cause unnecessary pressure on a large area of ​​tissue, affecting local blood circulation, causing ischemia and hypoxia in the surrounding tissues, and increasing the risk of tissue damage and necrosis.

[0004] Secondly, it is difficult to accurately control the pressure of overall compression. Too little pressure cannot effectively stop bleeding, while too much pressure may further damage blood vessels and surrounding tissues, aggravate bleeding or cause new complications. Different patients have different physical conditions and tolerances, and the appropriate pressure required for the same wound also varies. However, overall compression hemostatic devices are often difficult to flexibly adjust according to individual differences, making it difficult to achieve the best hemostatic effect in actual applications.

Similarly, the recovery winding roller 34 can be taken out and the release paper can be cut off and then re-pasted on the recovery winding roller 34, so that the use of a new blanket can be restarted; A blanket input layer 61 and a release paper recovery layer 62 are arranged inside the blanket connecting belt 6.
