Peripheral vascular comprehensive tester

Abstract

The invention relates to the field of medical instruments, and particularly relates to a peripheral vascular comprehensive tester which comprises a shell, a single-chip microcomputer, a detection probe, a blood-pressure cuff airbag and an air pump. The single-chip microcomputer is arranged in the shell, and the detection probe is electrically connected with the single-chip microcomputer; the air pump is arranged in the shell and is electrically connected with the single-chip microcomputer; the air pump is communicated with the blood-pressure cuff airbag and is used for pumping air into the blood-pressure cuff airbag; an electromagnetic valve electrically connected with the single-chip microcomputer is arranged at the position where the blood-pressure cuff airbag is communicated with the air pump; a pressure sensor electrically connected with the single-chip microcomputer is arranged on the blood-pressure cuff airbag; the detection probe includes a Doppler probe and a PPG (poly propylene glycol) probe, and the peripheral vascular comprehensive tester further comprises an air pulse control module. During testing of peripheral vascular, blood pressure is automatically captured through the pressure sensor, and a user does not need to fix blood flow waveform and a blood pressure monitor, so that convenience is brought to the user, and accuracy of measurement data is improved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a peripheral blood vessel comprehensive inspection instrument. Background technique [0002] Peripheral vascular disease refers to vascular diseases that occur in cardiovascular and cerebrovascular accidents. Peripheral vascular disease is further divided into arterial disease and venous disease. In order to detect arterial disease or venous disease, a two-way Doppler blood flow detector is designed, and the ankle-brachial index (ABI) of the patient is measured by combining the two-way Doppler blood flow detector and a sphygmomanometer. Lesion index) and toe brachial index TBI (an index to judge whether there is calcification in the tiny blood vessels of the toes). [0003] The Doppler blood flow detector in the related art comprises a Doppler probe, an ultrasonic coupler, a controller and a thermal printer; the Doppler probe is electrically connected to the controller through th...

Problems solved by technology

[0004] However, the Doppler blood flow detector in the related art needs to be used in conjunction with the sphygmomanometer. While fixing the blood flow waveform, the user must also take into account the inflation and deflation of the sphygmomanometer, and observe the first wave of Doppler with eyes. When the blood flow waveform appears, listen to the first Doppler sound with your ears, and then quickly record the blood pressure value when the first Doppler blood flow sound appears, and then input it into the computer to calculate the ankle-brachial index ABI and toe-brachial index TBI

Very inconvenient for users to use, it is easy to cause errors in measurement data
