The positive electrode line of the ultraviolet lamp and the negative electrode line of the ultraviolet lamp are placed on the outside of the sterilization chamber to prevent short circuit of the ultraviolet lamp. According to the technical solution provided by the present disclosure, the device can prevent the ultraviolet lamp from being short-circuited and disabled due to water entering the lamp part, and the ultraviolet lamp is heat-dissipated to make the sterilization more uniform and complete.

The present application provides a touch display screen, comprising: a display panel; a touch device located at the light emitting side of the display panel, and the touch device has a touch surface, comprising: a light emitting component for providing at least positioning light and at least high-energy light; a light receiver for detecting the light change amount of the positioning light on the touch surface due to touch, for determining the position of the touch on the touch surface; a biological sensor for determining whether a living body is close to the touch surface; and a controller for driving the light emitting component to selectively provide the positioning light and / or the high-energy light to the touch surface according to the judgment of the biological sensor. The present application can provide the ultraviolet light sterilization function of the touch panel while preventing the user from being negatively affected by the ultraviolet light during the touch operation, and saving the power consumption of the touch display screen.

This utility model relates to the field of medical device technology, and in particular to an ultraviolet (UV) light sterilization ultrasonic probe. It aims to solve the technical problem in related technologies where the probe can only remove necrotic tissue through the ultrasonic cavitation effect and mechanical vibration of the tip, failing to kill bacteria in the surgical area and thus requiring an external UV lamp source for sterilization. The UV light sterilization ultrasonic probe includes a probe body and a sterilization component. The probe body includes a working rod, a handle, and a transducer. The sterilization component includes an ultraviolet lamp. By mounting the ultraviolet lamp on the working rod, the UV light emitted by the lamp kills bacteria in the surgical area, achieving a synergistic sterilization effect while simultaneously cleaning the wound. This overcomes the technical problem of existing ultrasonic probes that can only remove necrotic tissue through the ultrasonic cavitation effect and mechanical vibration of the tip, failing to kill bacteria in the surgical area and thus requiring an external UV lamp source for sterilization.
