Apparatus and method for attitude detection of ultrasonic probe

Abstract

An ultrasonic probe attitude detection device and method, comprising: at least two thin-film pressure sensors, an ultrasonic probe wafer assembly, and a bonding part, wherein the ultrasonic probe wafer assembly and at least two thin-film pressure sensors are fixed on the bonding part On the same side, and all thin-film pressure sensors are distributed on the outside of the ultrasonic probe wafer assembly isolated from each other through bonding components. It not only uses a low-cost thin-film pressure sensor, but also avoids complex image recognition processing; and the pressure sensor is isolated from the ultrasound probe wafer assembly by bonding parts, completely eliminating the impact of the pressure sensor on the ultrasound probe patient's sign monitoring process.

Description

technical field [0001] The present invention relates to the technical field of medical testing equipment, in particular to a device and method for attitude detection of an ultrasonic probe. Background technique [0002] Clinically, ultrasonic Doppler image monitoring equipment is used to monitor the patient's physical signs, but during the long-term monitoring process, due to the voluntary or involuntary movement of the patient's body parts, non-disease-induced changes will occur in the ultrasonic Doppler image, and measurement errors may occur. Accurate problem, but can not judge in time whether it is the problem of the patient's blood flow state or the problem of the fixed probe, which may cause clinical misdiagnosis. [0003] In order to solve the above problems in the prior art, the pressure sensor is arranged on the surface of the probe, and the bonding state of the monitoring probe and the skin is realized through the pressure sensor, but the pressure sensor arranged o...

Problems solved by technology

[0002] Clinically, ultrasonic Doppler image monitoring equipment is used to monitor the patient's physical signs, but during the long-term monitoring process, due to the voluntary or involuntary movement of the patient's body parts, non-disease-induced changes will occur in the ultrasonic Doppler image, and measurement errors may occur. Accurate problem, but can not judge in time whether it is the problem of the patient's blood flow status or the problem of the fixed probe, which may cause clinical misdiagnosis

[0003] In order to solve the above problems in the prior art, the pressure sensor is arranged on the surface of the probe, and the bonding state of the monitoring probe and the skin is realized through the pressure sensor, but the pressure sensor arranged on the surface of the probe will inevitably affect the work of the probe at the pasted part; Some existing technologies use rigid fixing devices to firmly fix the probe on the skin surface of the human body to be monitored. On the one hand, the rigid fixing method is not conducive to the humanized experience of the patient. On the other hand, the rigid fixing method cannot effectively detect the probe on the surface of different parts. attitude

In addition, there are some methods regardless of cost, such as using infrared distance sensors, image scanning of bonding parts, and through complex training algorithms and training models, to finally judge the posture of the ultrasonic probe. The equipment is complicated and the cost is too high
