Photo-catalyst sterilizer for dental drill hand set

Abstract

The invention discloses a photocatalyst dental dental drill handpiece sterilizing device, which is characterized in that it is composed of a strong ultraviolet light source irradiation system and a photocatalyst compound liquid pressurized injection system, and the strong ultraviolet light source irradiation system is composed of a strong ultraviolet light source and a strong ultraviolet light source. The light source and the concentrating cavity of the dental drill handpiece are composed of a photocatalyst compound liquid pressurized injection system, which is filled with a container containing a photocatalyst compound sterilizing liquid compounded by nano-titanium dioxide, glutaraldehyde and long-flow gel resin. The pressurizing pump is formed by connecting the hose to the water and air ports of the dental drill handpiece. The beneficial effect of the present invention is to overcome the shortcomings of traditional high-temperature pressure steam or water bath sterilization that are not suitable for the inherent structural characteristics and use characteristics of dental drill handpieces, and avoid the high-temperature aging problems of aerodynamic and waterway components of high-speed turbine dental drills and high-speed turbine dental drills. It is difficult to eliminate the problem of "back suction" bacteria caused by the drill stop.

Description

technical field

[0001] The invention relates to a sterilizing device, in particular to a sterilizing device for a dental drill handpiece. Background technique

[0002] Usually in clinical oral cavity, the high-speed turbo dental drill handpiece is the conventional instrument that penetrates into the oral hard tissue and has the most bacteria-carrying environment in the oral cavity. Among the cross-infection of oral bacteria, 70% comes from the bacteria-carrying infection of the dental drill handpiece. Moreover, because the structure of the dental drill handpiece contains a pneumatic mechanism composed of polymer materials and a spray atomization device for cooling water, under high temperature conditions, some mechanisms will undergo reactions such as aging, melting, modification, and degradation, which will eventually cause the dental drill handpiece to become damaged. rapid damage. Therefore, traditional high-temperature pressure steam or water bath sterilization are not ...
