Problems solved by technology

[0005] The purpose of the present invention is to solve the problem of easy generation of air bubbles existing in the existing sound-conducting liquid, and provide a new application of antifreeze as a sound-conducting liquid, which can not only effectively reduce the bubbles generated when it is used as an ultrasonic transmission medium, but also improve its sound-conducting performance. Higher than water, rapeseed oil and other existing sound guide fluids

Embodiment Construction

[0014] The present invention will be further described below in conjunction with specific examples.

[0015] Buy the antifreeze used in automobiles from the market, add it to the sound guide cover of the medical ultrasonic therapy instrument, and make it between the piezoelectric wafer and the sound guide liquid resistance element at the front end of the sound guide cover, as the sound guide liquid of the ultrasonic waves use.

[0016] The above-mentioned medical ultrasonic treatment instrument is equipped with a water flow monitoring mechanism, which is equipped with two electrodes on the pipeline through which the water flow passes. When there is water flow passing through, the electrodes are turned on, and the monitoring mechanism does not operate; Motion alarm. In the normal use environment where degassed water was used as the sound-conducting fluid, the water flow monitoring mechanism gave an alarm after half a month. When troubleshooting, it was found that the water flo...

Abstract

The new application of antifreeze used as sound liquid relates to the new application of the antifreeze and aims at solving the problem that the prior sound liquid is easy to generate bubbles. The antifreeze is arranged between a sound wave emission point and a receiving point to be used as sound wave transmitting medium, especially to be used as sound wave transmitting medium in a sound shield on a curing head of a medical ultrasonic focusing therapy, thereby effectively reducing or eliminating the bubbles generated by the thermal effect, the mechanical effect and the cavitation effect of ultrasonic when the medical ultrasonic focusing therapy works, having the advantages of higher sound velocity and lower sound power attenuation, and being suitable for occasions applying the ultrasonic wave to use the antifreeze as the sound liquid.

Description

technical field [0001] The invention relates to a new application of antifreeze. Background technique [0002] The conduction medium of the sound wave can be gas, liquid or solid. Generally, liquid is used as the conduction medium of the sound wave, which is called the sound guide liquid. [0003] Especially in the application of ultrasonic waves, in the prior art, sound-conducting fluids such as water, rapeseed oil, castor oil, etc. are generally used as the conduction medium of ultrasonic waves. For example, in ultrasonic focused therapy devices, people generally use water as the conduction medium between the piezoelectric chip that emits ultrasonic waves and the treatment point that receives the focused energy of ultrasonic waves. Because air will affect the conduction of ultrasonic waves, the sound power will attenuate greatly. Therefore, air bubbles should be minimized or eliminated in the above-mentioned sound-conducting liquid. When the existing sound-conducting liq...
