Adjustable ultrasonic coupling agent automatic squeezing device

Abstract

An adjustable ultrasonic coupling agent automatic squeezing device comprises a squeezing module, a detection module, a connection module and a control module. The connection module can connect other modules together, an ultrasonic probe can be fixed on the connection module, the squeezing module uses a mechanical structure to squeeze a coupling agent bottle to squeeze out a coupling agent, and thecoupling agent is delivered to an agent outlet close to the ultrasonic probe through a pipeline of the connection module to move along with the probe and can be smeared on the body of a detected person; the detection module can utilize gas pressure change, resistance change or friction force change to indirectly judge smearing volume of the coupling agent to control output of the coupling agent or can only detect temperature; the control module can realize full-automatic control on output of the coupling agent manually or according to the detection module and can manually or automatically control heating power and on-off of the coupling agent according to temperature data of the detection module.

Description

technical field [0001] The invention relates to a medical device, in particular to an adjustable automatic extrusion device for ultrasonic coupling agent. Background technique [0002] The couplant used for ultrasonic inspection is an indispensable auxiliary material in the ultrasonic inspection work. In actual use, it is stored in the couplant bottle. The patient underwent ultrasonography. Therefore, for a sonographer, if it is conservatively estimated that 50 cases of ultrasound examinations are performed per day, and each case is squeezed twice, the sonographer needs to squeeze the coupling agent bottle hundreds of times a day, and repeat the manual operation every year. Squeeze the couplant bottle more than 20,000 times. Such long-term repetitive actions may cause early degenerative lesions of the metacarpophalangeal joints and finger joints of the hands. [0003] Ultrasound examination is a convenient, non-invasive, non-radiative, and relatively inexpensive imaging ex...

Problems solved by technology

However, manual application cannot control the amount of couplant used, which increases the cost of medical treatment and the complexity of the doctor's operation of ultrasonic equipment. At the same time, manual application of couplant may cause uneven application of ultrasonic couplant, and ultrasonic couplant is not applied in some places. , affecting the results of ultrasonography

Moreover, the temperature of the ultrasonic coupling agent is too low, which will cause a great stress response to the human body and easily affect the patient's medical experience.

[0004] Although the patent CN201620676935.6 realizes semi-automatic control, the control accuracy of the cylinder is low and the control difficulty is high, which is not practical. Although the patent CN201910112823.6 can automatically apply the couplant, repeated detection at the same position will waste a lot of couplant
