The integrated diaphragm valve of existing dental treating chair or the effect of electromagnetic valve are that driving air-flow, cooling blast and cooling water flow are divided into three groups for three dental handpieces uses, and each organizes air water stream is again to be controlled by the hanger of dental handpiece to open and close.
When taking off dental handpiece from hanger and stepping on foot switch, highly compressed driving air-flow promotes the dental handpiece turbine with 300,000 rpms of high speed rotating; By cooling water flow turbine and bearing are cooled off.Decontroling foot switch, disconnect when driving air-flow and cooling water flow, turbine is because inertia can be rotated further a period of time, extract out and drive gas in the trachea, and in driving gas flow tube, cooling water flow pipe, form negative pressure, when turbine stopped operating, negative pressure can enter the intraoral liquid dirt of patient in the water delivery feed channel of dental handpiece and its rear end from dental handpiece top resorption again, caused resorption to pollute.Same dental handpiece and water delivery feed channel thereof are when boring the tooth treatment for the next bit patient, and the dirt of their inside can enter in next bit patient's the oral cavity along with driving air-flow and cooling water flow, causes medical cross infection.Therefore, be necessary to stop fully dental handpiece its rear end water delivery feed channel resorption contamination phenomenon.It is that anti-resorption valve is installed on dental handpiece that existing anti-resorption pollutes the technology great majority, not stopping resorption as yet fully pollutes, sterilization method clinically is only limited to mostly to dental hand set disinfecting, and be difficult to the water delivery feed channel is carried out the sterilization of " people one machine ", brought very big medical cross infection risk to dental treatment.
The utility model content:
The purpose of this utility model is to propose a kind of preventing from resorbting pollution on dental curing platform device, to cooperate existing merely at the sterilization method of dental handpiece, avoids the medical cross infection that causes because of the resorption pollutant in the water delivery feed channel in dental treatment.
The device of this preventing from resorbting pollution on dental curing platform that the utility model proposes, it has the driving gas flow tube, cooling blast pipe and the cooling water flow pipe that are subjected to foot TRIP control, with the integrated diaphragm valve of air water stream packets control or electromagnetic valve, air water pipe line, mobile phone joint, it is characterized in that described driving gas flow tube and cooling blast pipe, be connected to the driving air-flow side branch that is not subjected to foot switch control in integrated diaphragm valve or electromagnetic valve upstream, porosely between the cooling blast pipe of described mobile phone joint and cooling water flow pipe communicate or be communicated with the mobile phone joint.With respect to driving the air-flow side branch, drive air-flow and be called main gas flow pipe again.
Drive the air-flow side branch and be connected with the isobaric source of the gas of driving gas flow tube.
Drive on the air-flow side branch and be connected to flow control valve.
The assembled body that drives air-flow side branch and driving gas flow tube and be the one pipe or be connected by threeway.
Device prevents that the principle that the dental treating chair resorption pollutes from being: when hanger took off dental handpiece and step on foot switch, dental handpiece ran well, and feeds the tributary that drives gas flow tube and cooling blast pipe, and its flow is less, does not influence the work of dental handpiece.When decontroling foot switch, disconnect when driving gas and cooling water flow, the dental handpiece turbine can continue to rotate a period of time owing to effect of inertia.Around here, originally feed the integrated diaphragm valve or the driving gas flow tube of electromagnetic valve upstream and the side of cooling blast pipe and prop up air-flow, can enter driving gas flow tube, cooling water flow pipe and the cooling blast pipe of dental handpiece rear end simultaneously respectively, keep positive air pressure in these pipes, avoid forming negative pressure.Dental handpiece is when stopping operating fully, and driving gas flow tube, cooling water flow pipe and cooling blast pipe does not have negative pressure, just can the intraoral dirt of resorption patient, thus prevented that the resorption in dental handpiece and its rear end water delivery feed channel from polluting.
