Internal drying device for dental handpiece

Abstract

The invention relates to an internal drying device for a dental handpiece, and belongs to the technical field of medical instruments. The device is composed of three detachable parts, including a dental handpiece containing cavity. Two ends of the cavity are an air inlet end and an air outlet end respectively. The air inlet end is connected with a hot air drying generation chamber. The air outlet end is connected with a dirt collecting chamber. A control panel is arranged on the outer wall of the hot air drying chamber and used for controlling wind strength and temperature. A handpiece containing frame is arranged in the dental handpiece containing cavity and perpendicular to the cavity. A plurality of handpiece containing holes are arranged on the handpiece containing frame. A pressure detector is arranged in the dirt collecting chamber. A pressure display is arranged on the outer wall of the dirt collecting chamber. A condensation pipe is arranged in the dirt collecting chamber. The three parts are combined through sleeves in use. During cleaning, the three parts are separately cleaned, and if one of the three parts breaks down, the part can be independently repaired, so that a plurality of devices can be flexibly combined for use, thereby improving the working efficiency. The dirt collecting chamber can also collect the dirt by another scheme, namely a disposable sealing bag made of a high-pressure-resistant and high-temperature-resistant material is sleeved at the orifice of the air outlet end of the dental handpiece containing cavity and can be discarded after being used. The dental handpiece containing cavity can rotate randomly, and a door is designed at the air inlet end on one side of the dental handpiece containing cavity, so that the handpiece is convenient to pick and place.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a drying device for an inner circuit of a dental handpiece. Background technique [0002] Dental handpiece is the most commonly used equipment in clinical treatment of stomatology. It uses compressed air as the power to drive the wind wheel to rotate at high speed, and then drives the dental bur to complete the drilling and grinding of the tooth. Because it is in close contact with the patient's saliva, blood, gingival crevicular fluid and dental plaque during the treatment process, its surface and internal turbine components and pipelines may be contaminated by different degrees of pathogenic microorganisms after use, so it belongs to clinically caused One of the most dangerous instruments for cross-infection must be cleaned and sterilized. In the process of cleaning and sterilizing mobile phones, it is easy to produce hygienic corners, breed bacteria, and easily cause ...

AI Technical Summary

Problems solved by technology

[0005] In view of the above technical problems, the present invention provides a drying device for the inner circuit of a dental handpiece. On the one hand, it further solves the cross-infection caused by incomplete cleaning and sterilization of the inner channel of the mobile phone, and at the same time, it can dry the inner channel of the mobile phone in batches. The device is also more convenient than the existing technology when cleaning, disinfecting and maintaining it. At the same time, it is more flexible during use, and multiple devices can be used in combination at will.
