AI Technical Summary

Technical Problem

Existing surgical oxygen masks suffer from problems such as long oxygen supply lines, delayed feedback, drug condensation, and interference during mode switching when switching oxygen supply modes, which affect the convenience and effectiveness of surgery.

Method used

A surgical oxygen mask was designed, which employs multiple oxygen inlet channels and a switching device. The guide port is switched by rotating the rotating column, and it can be directly connected to auxiliary equipment to reduce pipeline losses. It also achieves rapid mode switching and drug delivery through a one-way valve and a nebulizer.

Benefits of technology

It enables rapid and convenient switching of oxygen supply modes, reduces drug consumption, improves the convenience of surgery and the oxygen supply effect, ensures that drugs directly enter the patient's respiratory and circulatory systems, and avoids interference between modes.

Abstract

This invention discloses a surgical oxygen mask, relating to the field of surgical medical device technology. It includes a mask body and an oxygen inlet body, with multiple oxygen inlet channels on the oxygen inlet body. A rotating column is mounted on the mask body, one end of which is rotatably connected to the mask body, while the other end passes freely through the oxygen inlet body. The multiple oxygen inlet channels are evenly distributed circumferentially around the rotating column. A blocking groove is provided within the oxygen inlet body to separate the oxygen inlet channels. A blocking disc, which cooperates with the blocking groove, is mounted on the rotating column, and the blocking disc has a guide port. The rotating column and blocking disc allow for rapid switching between different oxygen inlet modes. Furthermore, because the auxiliary equipment is directly connected to the oxygen mask, losses caused by medication and pressure within the oxygen delivery pipeline during oxygen inlet are reduced. The rapid switching function also avoids interference between different oxygen inlet modes, greatly improving the convenience of surgery and demonstrating strong practicality.
