Blood flow detector

Blood flow detectors are medical testing devices that can detect microfluids in human blood vessels. They can convert fluid flow signals into processable electrical signals, which can then be analyzed by professional doctors to detect vascular diseases. This detection method does not require skin incision or other invasive operations, nor does it affect the patient's normal activities. It can evaluate the state of blood vessels before surgery or other invasive operations to determine the safety of surgery or treatment.

Blood flow detectors, including intravascular blood flow detectors and extravascular blood flow detectors, wherein:

1. An intravascular blood flow detector, comprising a catheter and a guide wire, wherein one end of the catheter and the guide wire is fixedly connected with a compressor, and the compressor is communicated with the intravascular catheter through the guide wire. The intravascular blood flow detector also includes a pressure sensor, which is connected to the outside of the compressor and communicated with the compressor, and the pressure sensor is connected to a microprocessor, and the microprocessor collects intravascular pressure signals through the pressure sensor.

2. An extravascular blood flow detector comprises a closed extravascular detection cavity, wherein a pressure sensor is arranged inside the cavity, and the pressure sensor is connected to a microprocessor through a wire, and the microprocessor collects an extravascular pressure signal through the pressure sensor.

All of the above blood flow detectors can realize real-time detection of blood flow. Among them, the intravascular blood flow detector can collect blood flow signals in real time with little damage to blood vessels; the extravascular blood flow detector can collect blood flow signals in real time, but it requires cutting the skin, which causes certain damage to the blood vessels.
