Device and method for automatically controlling blood occlusion of carotid artery

Abstract

The invention discloses a device and a method for automatically controlling blood occlusion of the carotid artery. The device is formed by an installation base plate, a slide support, an air pressure blocking module, an air pressure control module and n wireless blood oxygen measurement modules. The air pressure control module is installed in an air pressure control module guide groove of the slide support which is arranged in a slide support guide groove of the base plate. The air pressure blocking module is positioned below the air pressure control module and connected with the air pressure control module into a whole. The wireless blood oxygen measurement modules are used for calculating blood oxygen values. A single-chip microcomputer in the air pressure control module receives the blood oxygen values measured by the wireless blood oxygen measurement modules through wireless communication circuits, collects pressure of pressure sensors and automatically controls pressurization and pressure reduction of air pressure of the air pressure blocking module. The air pressure control module and single-chip microcomputers in the blood oxygen measurement modules control air pressure and blood oxygen measurement according to program control processes. By means of the method adopting wireless communication, structural design is simplified, redundant wire connection is eliminated, and the device is scientific, reliable, practical and good in effect.

Description

1. Technical field [0001] The invention relates to a medical instrument, in particular to an instrument for compressing the carotid artery and blocking the blood flow of the carotid artery from outside the body. 2. Background technology [0002] For the detection and treatment of certain diseases, it is necessary to temporarily block the carotid artery blood flow on one side of the patient. In clinical practice, doctors often do it manually. However, due to the doctor's experience and fatigue, the manual operation often affects the diagnosis and treatment effect. Chinese patents ZL89221081.8, ZL92231446.2, and ZL99253968.4 disclose three kinds of carotid artery compression devices for blocking the blood flow of the carotid artery, which solve the problem of blocking the blood flow of the patient's carotid artery by manual operation by doctors. However, these three devices still have the following problems: 1 cannot monitor the blood flow occlusion effect and timely adjust th...

Problems solved by technology

[0002] For the detection and treatment of certain diseases, it is necessary to temporarily block the carotid artery blood flow on one side of the patient. In clinical practice, doctors often do it manually. However, due to the doctor's experience and fatigue, the manual operation often affects the diagnosis and treatment effect.

Chinese patents ZL89221081.8, ZL92231446.2, and ZL99253968.4 disclose three kinds of carotid artery compression devices that block the blood flow of the carotid artery, which solves the problem of blocking the blood flow of the carotid artery by doctors with bare hands

However, these three devices still have the following problems: 1 cannot monitor the blood flow occlusion effect and timely adjust the applied pressure and occlusion time according to the blood flow occlusion effect; 2 cannot obtain carotid blood flow occlusion data, including the Pressure, pressure application time, blood flow blocking effect, etc.

Chinese patent ZL200910058468.5 solves the above problems, but has new shortcomings: 1. The overall structure is not reasonable, too many and too long connections may affect other operations in diagnosis and treatment; The reliability is not good; 3. There are too few blood oxygen sensors, and only one part can be monitored; 4. The blood oxygen sensor uses a transmission method and is connected by wire, which is not conducive to operation
