Dental sterile supply system

Abstract

The invention discloses a dental sterile supply system which comprises a normal saline bag, a peristaltic pump, a pneumatically-controlled electric switch, a water selector valve, a compressor, a filter, an ultraviolet light processing device, a first detachable connecting pipe connected with a dental handpiece, a second detachable connecting pipe connected with a three-gun, a foot switch, and a gas selector valve; the normal saline bag is connected with a water inlet of the water selector valve through a flexible water pipe; the flexible water pipe runs through space between a roller and a guide groove of the peristaltic pump; a water outlet of the water selector valve is divided into two ways which are respectively connected with the first and the second detachable connecting pipes; the compressor, the filter and the ultraviolet light processing device are orderly connected and are divided into two ways through the foot switch, and the two ways are respectively connected with a gas inlet of the pneumatically-controlled electric switch and a gas inlet of the gas selector valve; a gas outlet of the gas selector valve is divided into two ways which are respectively connected with the first and the second detachable connecting pipes; the circuit of the pneumatically-controlled electric switch is connected with the circuit of the peristaltic pump. The system is simple in structure and convenient for use, and fundamentally solves the problem of sterile water supply and gas supply in dental treatment.

Description

technical field [0001] The invention relates to an aseptic supply system in dental clinical treatment. Background technique [0002] The water source pollution of the comprehensive treatment chair waterway pipeline has been widely concerned at home and abroad. On the one hand, the pollution of the water pipeline of the oral comprehensive treatment chair comes from the moment the mobile phone stops working during the clinical treatment of oral diseases. The negative pressure formed inside the machine makes the saliva, blood, microorganisms, etc. in the patient's mouth suck back into the dental handpiece, and thus enter the oral cavity The water pipes of the comprehensive treatment table pollute the water system; on the other hand, it comes from the heterotrophic bacteria in the oral water supply system. These exogenous microorganisms are easy to attach to the surface of objects soaked in water, forming a layer of biofilm (biofilm). Biofilm is a phenomenon that occurs natura...

Problems solved by technology

However, the fastest rotation speed of the device is only 60,000 rpm, and there is no air system, which cannot meet the 300,000 rpm rotation speed required for oral clinical treatment and the needs of suction, water flushing, and air flushing, and the equipment is expensive. Dental handpieces are electric, highly specific, and expensive, and the existing pneumatic dental handpieces cannot be used in conjunction with them
