The technical background of the development of tourniquet

In the past, the hose-type tourniquets used in domestic hospitals have common problems such as cross-use, repeated use, random storage, non-sterilisation or disinfection, or excessive disinfection of the septum, causing serious contamination of the tourniquet. The specific performances are as follows: 1. The pathogens picked up by the tourniquet are far beyond the "Hospital Disinfection Hygienic Standards" (GB15982-1995) 4.2.3. The total number of bacterial colonies in contact with the skin should be ≤200cfu/g or 100cm2: Diseased microorganisms should not be detected as "required, and conditional pathogens are detected (this is reported in a large number of domestic literature). 2. The medical devices, utensils and articles that are in contact with skin and mucous membranes must meet the disinfection level as required by Article 12 of Chapter 3 of the Hospital Infection Management Measures (Decree No. 48 of the Ministry of Health of the People's Republic of China); The invasive medical devices such as blood collection must be operated in accordance with the relevant regulations. 3. Studies have shown that flat tourniquets can better alleviate patient pain and improve puncture success rate than round tourniquets. Affected by internationalization, the application range of domestic disposable tourniquets will gradually shift from the use of military or field “emergency” hemostasis to “conventional” treatment of infusion, blood draw and hemostasis.
