Embodiment Construction

[0017] like figure 1 As shown, the non-contact blood flow monitoring device includes a cuboid-shaped flow channel container 1. At the bottom of the flow channel container 1, both ends of the flow channel container 1 are respectively provided with a liquid inlet 2 and a liquid outlet 3, as shown in the figure. figure 2 As shown, both the liquid inlet 2 and the liquid outlet 3 are connected to a blood transfusion circuit 9, and the blood transfusion circuit 9 can be connected to an artificial heart system, such as a blood pump, to monitor the blood flow of the pump.

[0018] like image 3 As shown, a sheet-shaped permanent magnet 9 is arranged inside the flow channel container 1 , and the permanent magnet 9 is installed on the elastic body 7 , and the elastic body 7 is installed in the flow channel container 1 through the pin shaft 8 . Permanent magnet 9 and elastic body 7 (eg Figure 4 shown) as a sensor-actuated unit in contact with a fluid (such as blood), such as Figure...

Abstract

The invention discloses a non-contact blood flow monitoring device which comprises a cuboid-shaped flow channel container, and a liquid inlet and a liquid outlet are formed in the bottom of the flow channel container and the two ends of the flow channel container respectively. A sheet-shaped permanent magnet is arranged in the flow channel container, the permanent magnet is mounted on an elastic body, and the elastic body is mounted in the flow channel container through a pin shaft; a receiver is arranged outside the flow channel container and detects the angular position of the permanent magnet in real time; the device is simple in structure, low in cost and convenient to use, achieves the function of non-contact flow online real-time detection, can achieve online real-time flow monitoring, is particularly suitable for life support type intelligent equipment, avoids medical accidents caused by the fact that the flow cannot be rapidly maintained due to sensor failure, and improves the safety of the equipment.

Description

technical field [0001] The invention relates to a non-contact blood flow monitoring device, which is used for monitoring flow, and is especially suitable for flow monitoring in contact with blood. Background technique [0002] With the continuous development of science and technology and the continuous improvement of people's living needs, the market has developed sensors based on various working principles, such as pressure sensors, temperature sensors and flow sensors, which are applied to all aspects of life and scientific research. . For example, flow sensors that monitor gas or liquid flow. Most of the existing flow sensors are structures in complete contact with the fluid, which are expensive to manufacture and maintain. Especially for blood flow monitoring, direct contact of monitoring components with blood may cause problems such as coagulation and contamination. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to ...
