3 results about "Ultraviolet Light Sterilization" patented technology

The present disclosure relates to a water purifier faucet device and control method for enhancing ultraviolet light sterilization. The device can include a water inlet pipe, a sterilization chamber, a water outlet pipe, a positive electrode line of an ultraviolet lamp, and a negative electrode line of the ultraviolet lamp. The water outlet pipe is a bent pipe. The sterilization chamber is connected to the water inlet pipe and the water outlet pipe. The sterilization chamber is provided with a light chamber near the water outlet pipe. The light chamber is internally provided with an ultraviolet lamp bead and an ultraviolet lamp circuit board. The ultraviolet lamp bead irradiates and sterilizes the incoming water of the water inlet pipe through the sterilization chamber. The ultraviolet lamp bead is attached to the light chamber for heat dissipation of the ultraviolet lamp. 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.

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.

This utility model discloses a medical gas purification device, including an L-shaped frame and a left movable arm. Two sets of left movable arms are arranged on the side wall of the L-shaped frame, and the left movable arms are movably connected to the L-shaped frame. A right movable arm is provided at the end of each left movable arm furthest from the L-shaped frame. A movable shaft is provided at the end of each right movable arm closest to the left movable arm, and the right movable arm is movably connected to the left movable arm via the movable shaft. A connecting plate is provided on the outside of the L-shaped frame, and the connecting plate is movably connected to the right movable arm. A purification box is installed on the side wall of the connecting plate, and a sterilization tube is installed on one side of the purification box. An air inlet pipe is installed at the port of the sterilization tube. This utility model not only achieves convenient and flexible adjustment of the purification box's position, facilitating multiple purification processes and uniform ultraviolet light sterilization of anesthetic gases through reciprocating oscillation, but also improves the purification effect of anesthetic gases.
