Abstract

The invention discloses a correction method for a color doppler ultrasonic diagnostic instrument detection device. The correction method comprises that the detection device drives artificial blood to flow in a circulatory system at a certain speed through a circular pump, when the artificial blood passes through a flowmeter, the electronic flowmeter feeds acquired flow velocity information back to a control system, during the whole flow velocity adjusting process, the control system records instantaneous values in a curve, and a liquid crystal display screen displays the curve, when the flow velocity in the whole closed circulation system is stabilized to be preset values, the artificial blood flows stably for a long time in an artificial membrane at a certain speed, and the color doppler ultrasonic diagnostic instrument can be detected at the moment.

Description

technical field [0001] The invention relates to a calibration method for a detection device of a color Doppler ultrasonic diagnostic instrument. Background technique [0002] At present, the detection device of the color ultrasonic Doppler diagnostic instrument at home and abroad mainly uses a single pump to control the flow of imitated blood, a rotameter to measure the flow velocity of the imitated blood, and manually control the speed of the pump to control the flow velocity of the imitated blood in the body membrane test body. In order to detect the accuracy of the color ultrasound Doppler diagnostic instrument. But there are following problems in existing detection device: [0003] 1. The detection time is not long; 2. The detection uncertainty is large; 3. The low-speed blood flow is unstable; 4. The flow rate measurement range is low; 5. The pump system has poor anti-interference; 6. The measuring device is bulky and inconvenient to carry; 7. High price and poor main...
