Oxygen saturation determinator application technology in radial artery paracentesis postoperation haemostasis method

Abstract

The invention relates to an oxygen saturation determinator application technology in a radial artery paracentesis postoperation haemostasis method; technical features comprise the following steps: 1, withdrawing a sheath tube for 2-3 cm after radial artery paracentesis, using a TR-Band radial artery haemostasis device to aim as a puncture point, using an adjustable buckle to fix a band on a wrist, opening a fresh air cap, using an injector to inject air so as to expand a balloon, compressing to stop bleeding, and removing the sheath tube; 2, compressing the radial artery, slowly releasing air, using the oxygen saturation determinator to measure oxygen saturation changes until reaching 97%, and bleeding should be avoided. The method can stop bleeding without blocking, is simple in operation, can greatly reduce complications, thus reducing 30-day radial artery obturation incidence rate by 75%.

Description

Technical field: [0001] The invention belongs to the technical field of medical methods, in particular to the application technology of a blood oxygen saturation measuring instrument in a hemostasis method after radial artery puncture Background technique: [0002] Percutaneous coronary intervention (PCI) refers to a treatment method that dredges the narrowed or even occluded coronary artery lumen through cardiac catheterization, thereby improving the blood perfusion of the myocardium. With the miniaturization of coronary intervention equipment, percutaneous radial artery puncture for coronary angiography and coronary angioplasty (PT-CA) has become a preferred method. At present, it has been widely used in clinical practice. With the increase of application, postoperative complications gradually increase. Its common complications include: 1. Forearm pain or discomfort Radial brachial artery pain, the incidence rate reported in the literature (4.16%). 2. Local hemorrhage, t...

AI Technical Summary

Problems solved by technology

In the past, the airbag used had enough fullness, and the force should be able to touch the radial artery pulse, and the local skin temperature and color should be normal. The standard air volume of the TR--Band airbag is 13ml, and the maximum air volume is 18ml. The application has no reference index and depends entirely on personal experience and habits, so the treatment effect has not been very satisfactory
