Description

Technical Field

[0001] The invention relates to the field of ultrasound medical auxiliary equipment, and in particular to a coupling agent coating and cleaning device for an ultrasound probe. Background Art

[0002] Ultrasonic examination is a method of diagnosing diseases by using the reflection and attenuation patterns of various organs and tissues in the body to ultrasound waves when they propagate in the human body. Ultrasonic waves have good directionality. When propagating in the human body, they encounter tissues and organs of different densities, which results in reflection, refraction and absorption. Based on the distance, strength and number of echoes displayed on the oscilloscope, as well as whether the attenuation is obvious, the activity functions of certain organs in the body can be displayed, and it can accurately identify whether tissues and organs contain liquid or gas, or are solid tissues.

[0003] During the ultrasonic examination, the probe is in direct contact with the patient's body, posing a risk of cross-infection. Medical staff usually clean the surface of the probe with a tissue after each ultrasonic examination. Some medical staff will also spray medical alcohol on the probe for disinfection.
