Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical auxiliary equipment technology, and in particular to a protective cover for manual oiling of dental handpieces. Background Technology
[0002] Dental handpieces are core tools in dental treatment, and their internal precision bearings require regular lubrication to maintain performance. Currently, the mainstream maintenance method combines machine lubrication with manual lubrication. During manual lubrication, the operator sprays lubricating oil (the front end is wrapped in a paper-plastic bag) into the handpiece's air intake, and the airflow drives the oil mist into the internal bearings. However, the oil mist can generate aerosols that can enter the respiratory tract, causing respiratory discomfort for the operator. Although dental handpieces can be lubricated by machine, the lubrication effect is still unsatisfactory, necessitating manual lubrication to ensure instrument performance and safe use.
[0003] In summary, the following technical problems still exist in the existing technology: (1) Oil spray: During oil filling, the high-pressure airflow carries the lubricating oil to form an aerosol, which is sprayed out in reverse from the gaps in the mobile phone and the oil filling interface, contaminating the operator's hands, face and working environment. Lubricating oil contains mineral oil, synthetic esters and other components. Long-term exposure can lead to skin inflammation, respiratory irritation, and even potential carcinogenic risks (such as polycyclic aromatic hydrocarbons containing PAHs); (2) Environmental pollution: Oil mist settles on the surface of the workbench, forming sticky residues, which increases the risk of cross-infection and cleaning costs; (3) Resource waste: Paper-plastic packaging bags are consumables, increasing consumable costs. If manual oiling is not completely effective, it increases equipment maintenance costs and turnover rate; Therefore, it is necessary to propose a protective cover for manual oiling of dental handpieces, and to provide a new technical solution to the technical problems mentioned in the above patent.
[0004] Therefore, we need to design a protective cover for manual oiling of dental handpieces to solve these problems. Utility Model Content
