Since the tube of the medical device is an elongated tube, it has physical properties such as capillary phenomenon and syphon phenomenon. Because of this physical property, the water will continue to come out even if you stop using it unless you install a separate device in the tube connected to the handpiece or three-way syringe.

In view of this, a backflow device was installed in the tube to allow the water to stop immediately after the use of the medical device.

However, the saliva, blood, or other aerosol-like liquid substance of the patient is sucked into the tube by the reflux device, there is a problem that the tube is contaminated.

As described above, the biofilm is formed in the tube of the medical device so that the patient may brush their teeth with contaminated water, and spray the specific part of the patient at a high speed to cause infection by bacteria.

In addition, in the case of the high-speed handpiece, the aerosol is formed by the polishing burr that rotates at high speed as water is used as the coolant, which may contaminate the air of the entire dental office, thereby threatening health to dentists and other patients. Can cause problems.

Such contamination in the tube is limited in preventing contamination inside the elongated tube by methods such as external disinfection.

The present invention has been made in view of the above point, the object of the present invention is to provide a dental medical device that can be sterilized easily and permanently inside the elongated tube.
