Sterile matching device of dental handpiece

Abstract

The invention provides a sterile matching device of a dental handpiece, which comprises a compressor, a compressed hot air radiator, a compressed air cooler, a cooling gas centrifugal water distribution filter, a cooling gas heating heat exchanger, a gas pressure regulating valve, a foot switch, a compressed air sterile filter, a sterile bagged water pressing device for human body infusion, a special pipeline for supplying air and water to the handpiece, the sterilized dental handpiece and the like. Wherein a compressed air sterile generation device can provide sterile, dry and clean compressed air to drive the air turbine handpiece to run at a high speed, sterile bagged water for human body infusion in a water supply device, a pressure container of the sterile bagged water and other devices can provide sterile distilled water or normal saline for cooling the dental handpiece. The sterile compressed air and the sterile water provided by the device enable the sterile operation of the dental handpiece to be possible, and patients and medical staff can be protected from cross infection of diseases.

Description

technical field [0001] The invention relates to an aseptic matching device of a dental handpiece, which belongs to the field of oral aseptic operation and the field of machinery. Background technique [0002] The air turbine handpiece in oral treatment is a widely used instrument at present. It needs a certain pressure of compressed air to drive the wind wheel in the handpiece to drive the drill to rotate and cut teeth and other hard tissues. Because of its high rotation speed ( About 300,000-400,000 revolutions per minute) Cooling water or water mist is required to cool the cutting part during cutting. [0003] Over the years, the dental operations performed by gas turbine handpieces have been carried out in a sterile state. [0004] First, the compressed air required by the mobile phone does not have a sterile filter device, whether it is a centralized air supply in a large hospital or a single air supply in a small clinic. The air pipelines and intermediate control compo...

AI Technical Summary

Problems solved by technology

[0004] First, the compressed air required by the mobile phone does not have a sterile filter device, whether it is a centralized air supply in a large hospital or a single air supply in a small clinic. The air pipelines and intermediate control components used cannot be sterilized. Therefore, microorganisms are extremely Easy to grow, harmful microorganisms are likely to exist in it, so the supply of compressed air has always been one of the infection risks of dental handpieces

[0005] Second, the cooling water required by mobile phones, whether it is centralized water supply, such as using civil tap water, special water pumps, etc., or air pressure water tanks used by stand-alone treatment machines, all use sterile water, even if it is filled with sterile water. Bacterial water also has the risk of bacterial growth, and it will quickly become sterile after use, because the pipelines and control components used for water supply cannot be removed and sterilized after long-term use

[0006] Third, good and bad mobile phones used in surgical cutting vary, and a considerable number of mobile phones are not sterilized in place or have air-water resorption phenomenon, which will also cause iatrogenic cross-infection

[0007] For highly contagious diseases, especially diseases that can be transmitted through oral contact, under such dental treatment conditions, it is very easy to induce infection, and some surgical operations are also very prone to postoperative infection when operated in a sterile state. Therefore, in Serious risks of dental treatment under aseptic conditions
