Double-air-bag radial artery compressor under finger pulse oxygen plethysmography wave monitoring and pressure reduction method of double-air-bag radial artery compressor

Abstract

The invention relates to the technical field of radial artery coronary angiography or interventional postoperative radial artery compression hemostasis, in particular to a double-air-bag radial arterycompressor under monitoring of finger pulse oxygen plethysmography waves and a pressure reduction method of the double-air-bag radial artery compressor. The device comprises a wrist strap and a finger vein oxygen monitor, wherein the wrist strap is provided with a radial artery compression air bag, an ulna artery compression air bag and a micro air pump used for inflating the air bags; and air pressure sensors are installed in the radial artery compression air bag and the ulna artery compression air bag respectively. The pressure reduction method comprises the following steps of: judging whether the radial artery compressor is in an open hemostasis state or not by judging whether the finger pulse oxygen monitor has a curve waveform or not, and decompressing the radial artery compressor onthe basis of the waveform. According to the double-air-bag radial artery compressor under monitoring of the finger pulse oxygen plethysmography waves and the pressure reduction method of the double-air-bag radial artery compressor, the open type hemostasis concept is followed, the compression area is more accurate, the compression strength is more accurate, the pressure reduction time is more accurate, and the occurrence rate of radial artery occlusion and radial artery stenosis is reduced.

Description

technical field [0001] The invention relates to the technical field of radial artery compression and hemostasis after radial artery coronary angiography or interventional therapy, in particular to a double-balloon radial artery compressor and a decompression method thereof under the monitoring of finger pulse oxygen plethysmography waves. Background technique [0002] Local pressure at the puncture site after radial coronary angiography or interventional therapy is a common method for hemostasis. However, excessive postoperative pressure or too long time can lead to local endothelial cell damage, slow blood flow, and local hypercoagulable state. Increased risk of blood clots. In order to prevent bleeding, the traditional radial artery compressor has a relatively large compression force and a relatively fixed decompression time. Usually, the decompression is performed every two hours after the operation. However, there is no scientific theoretical basis for this method. Hemo...

Problems solved by technology

Since the palm is supplied with both the radial artery and the ulnar artery, even if the radial artery occlusion occurs after surgery, clinical symptoms such as hand ischemia, necrosis and dysfunction rarely occur, so the radial artery occlusion is difficult to be observed
