Description

TECHNICAL FIELD

[0001] The utility model relates to medical equipment technical field especially, and it is a kind of skin auxiliary pinch fixed clamp based on abdominal injection. BACKGROUND

[0002] Low molecular weight heparin is a new generation of heparin anticoagulant drugs developed in the century, which is obtained by depolymerization of ordinary heparin. It is mainly used for the treatment and prevention of deep venous thrombosis in clinic, and it has the characteristics of good subcutaneous injection absorption, high bioavailability, long half-life in vivo, small bleeding tendency, etc. It has become the basic prevention and treatment measure for deep venous thrombosis and / or pulmonary embolism. The main administration route of low molecular weight heparin is subcutaneous injection. Because the abdominal subcutaneous fat layer is thick, the tissue is loose, and the capillary is relatively less, the abdomen is preferentially selected. Domestic and foreign anti-coagulant injection related research reports show that the adverse reactions after subcutaneous injection are mostly related to technical operation. A large number of domestic studies have confirmed that the vertical needle injection method can reduce the adverse reactions of low molecular weight heparin subcutaneous injection. The latest low molecular weight heparin injection process abroad also recommends that the skin wrinkle be pinched vertically when injecting.

[0003] At the same time, it is shown that the abdominal vertical wrinkle method (pinching the skin of the abdominal wall to form a skin wrinkle, and vertically inserting the needle at the highest point of the skin wrinkle) can reduce the misentry into the muscle layer and damage to the peritoneum, and thus reduce the probability of subcutaneous bleeding. However, in clinical practice, it is found that due to the difference in the size of the hands of nursing staff, some nurses pinch the skin with their left hands, and the right hand cannot complete the injection, so the needle head needs to be fixed with one hand and injected with the other hand, which makes it impossible to keep the skin pinched continuously. If the left hand keeps the skin wrinkle, the right hand cannot stably fix the needle head, which causes the position of the needle head to be unstable during injection, and it is easy to cause the needle head to be bent, resulting in multiple punctures, increasing the pain and bleeding risk of the patient and affecting the injection rhythm. Therefore, we propose a skin auxiliary pinch fixed clamp based on abdominal injection. CONTENT OF THE UTILITY MODEL
