Description

A cleaning device for medical equipment

Technical field

The present invention relates to the technical field of medical device cleaning, and in particular to a cleaning device for medical devices.

Background technique

Medical device cleaning equipment is mainly divided into the following types. One is a medical fully-automatic cleaning machine, and the other is a medical ultrasonic cleaner. The medical fully-automatic cleaning machine relies on high-pressure jet spray, plus hot water for extensive disinfection and rinsing and drying. Dry machine is the main equipment used in hospitals to replace labor. Medical ultrasonic cleaners are mainly suitable for hospital scalpels, forceps, hemostats, endoscopic biopsy forceps, injection needles, syringes of various sizes, test tubes, glass pieces, dressing bowls, various plates, barrels, pressure gauges and other radioactive , contaminant, large-volume, high-cleanliness cleaning and disinfection.

After searching, it was found that in existing ultrasonic cleaners, medical instruments are usually soaked in cleaning fluid and started to be cleaned. However, after cleaning, the dirt will still remain in the cleaning fluid. When the medical instruments are taken out of the cleaning fluid, , dirt may re-adhere to medical devices, and the powerful ultrasonic cleaning may cause corrosion or damage to them.

Therefore, we propose a new medical device cleaning device that can improve the cleaning effect without leaving residual stains on the surface of the device after cleaning.
