AI Technical Summary

Technical Problem

In the existing technology, the cleaning effect of the needle holder is not good, the instruments are mixed up, and the frequency of use cannot be determined, which leads to a high risk of occupational exposure and an increased possibility of instrument damage.

Method used

An auxiliary cleaning device for dental bur holders was designed, which adopts a multi-layered stepped hollow design. The bur holder is fixed by inclined hollow partitions to ensure that the water flow is sufficient for rinsing. The spacing of the hollow partitions is adjusted according to the size of the bur holder for fixation to prevent it from falling off.

Benefits of technology

It improved the cleaning quality of needle holders, reduced the risk of cross-infection, prevented needlestick injuries, clarified the frequency of instrument use, and improved work efficiency and cleaning effect.

Abstract

The utility model discloses an auxiliary cleaning device for an oral cavity machine needle frame, which belongs to the technical field of oral cavity medical equipment and comprises a device body and a plurality of placement baskets. The device body comprises a bottom frame, a back plate and two vertical plates, the bottom frame is horizontally arranged, the back plate and the two vertical plates are vertically arranged at the edges of the three sides of the bottom frame, and a plurality of limiting beams are arranged between the two vertical plates; a plurality of groups of hanging plates are symmetrically arranged on the two vertical plates in the vertical direction in a layered manner, and are sequentially far away from the back plate from top to bottom; the plurality of placement baskets are respectively arranged on the plurality of groups of hanging plates to form a stepped structure with the device body; a plurality of hollowed-out partition plates are obliquely arranged on the placement basket, and a machine needle frame is placed on the hollowed-out partition plates. The machine needle frame cleaning device solves the problems that a plurality of machine needle frames are poor in cleaning effect, instruments are confused, and the use frequency of the instruments cannot be determined, meanwhile, the high risk of needle pricking occupational exposure in the cleaning process of the machine needle frames is reduced, and the problems that the instruments are damaged are solved.
