Embodiment 1

[0037] Such as Figure 3-5 As shown, a device that can automatically smear couplant on an ultrasonic probe, said device that automatically smears couplant includes an ultrasonic probe module 1-4, a comprehensive monitoring sensor 1-3, a single-chip microcomputer 1-1, and an air pump module 1- 2. The nozzle 3-1; the ultrasonic probe module 1-4, the comprehensive monitoring sensor 1-3, and the air pump module 1-2 are all connected to the single-chip microcomputer 1-1; the air pump module 1-2 passes through the hose and the nozzle 3- 1 connection.

[0038] The ultrasonic probe module 1-4 includes a generator and a receiver, the generator transmits ultrasonic waves to the patient, the receiver receives ultrasonic echo signals, and the ultrasonic echo signals are converted into digital by the first A / D conversion circuit 1-8 The ultrasonic echo signal is sent to the single-chip microcomputer 1-1 for calculation and processing.

[0039] Further, the single-chip microcomputer 1-1 e...

Embodiment 2

[0051] The present invention also provides a method for automatically applying coupling agent on the ultrasonic probe, using the above-mentioned device, comprising the following steps:

[0052] Step 1: When the ultrasonic probe is placed on the patient, the substrate 2-8 in the pressure sensor squeezes the cantilever beam 2-3, causing the resistance value of the strain gauge 2-2 to change and it is regarded as starting to check the patient. The single-chip microcomputer 1 -1 Control the air pump module 1-2 to spray a small amount of couplant; the single-chip microcomputer 1-1 calculates the thickness of the fat according to the data monitored by the ultrasonic probe module 1-4, and calculates the amount of sprayed couplant according to the fat thickness. The formula for the fat thickness is H=(T*V) / 2, where H represents the thickness of fat, T represents time, and V represents the propagation velocity of ultrasonic waves; the formula for spraying coupling dose L1 is L1=D*X*H, w...

Abstract

The invention provides a device capable of automatically smearing a coupling agent on an ultrasonic probe. The device capable of automatically smearing the coupling agent comprises an ultrasonic probe module, a comprehensive monitoring sensor, a single chip microcomputer, an air pump module and a nozzle, wherein the ultrasonic probe module, the comprehensive monitoring sensor and the air pump module are all connected with the single chip microcomputer. and the air pump module is connected with the nozzle through a hose. By monitoring different patients in real time and automatically and comprehensively judging the amount required for spraying the coupling agent, the workload of doctors can be reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of ultrasonic probes, in particular to a device capable of automatically applying a coupling agent on an ultrasonic probe. Background technique [0002] During ultrasonic examination, the air between the probe and the patient's skin will hinder the transmission of ultrasonic waves into the human body. In order to obtain high-quality and clear images, it is necessary to use a liquid conductive medium to connect the probe and the patient's body surface. This medium is the commonly used ultrasonic coupling agent. . The purpose of using an ultrasonic coupling agent is firstly to fill the tiny gaps between the contact surfaces, so that the tiny amount of air in these gaps does not affect the penetration of ultrasound; secondly, through the "transition" effect of the coupling agent, the acoustic impedance between the probe and the skin The difference is reduced, thereby reducing the reflection loss of ultrasonic ...
