Description

Technical Field

[0001] The invention relates to the technical field of disinfection devices, and in particular to a disinfection device for a probe used in medical ultrasound. Background Art

[0002] Ultrasonic probe is a device that transmits and receives ultrasonic waves during ultrasonic testing. The performance of the probe directly affects the characteristics of ultrasonic waves and the detection performance of ultrasonic waves. The probe used in ultrasonic testing is a transducer that uses the piezoelectric effect of materials to achieve electrical energy and acoustic energy conversion. In the clinical medical process, the ultrasound department must use the ultrasonic probe of the ultrasonic diagnostic instrument. When using the ultrasonic probe, it needs to be coated with coupling agent before contacting the human skin. Therefore, it is very easy for some germs to remain on the ultrasonic probe. In order to remove these germs, the ultrasonic probe needs to be cleaned and disinfected.
