AI Technical Summary

Technical Problem

The existing spray oxygen-infusing masks suffer significant oxygen loss when changing the medicine bottle, and the process is cumbersome, time-consuming, affecting the treatment effect and increasing the burden on staff.

Method used

A dual-channel drug delivery system was designed, which enables rapid replacement of medicine bottles through a gear and rack mechanism. The new medicine bottle is automatically positioned by gear meshing and a flexible clamp, and the sealing plate automatically seals the channel of the old medicine bottle to prevent oxygen loss and the entry of outside air.

Benefits of technology

It achieves high efficiency and airtightness in medicine bottle replacement, reduces oxygen loss, ensures treatment effectiveness, and reduces the labor intensity of staff.

Abstract

This invention provides a respiratory medicine spray oxygen delivery mask, relating to the field of medical devices. It includes a mask component with mask fixing straps on both sides; a connecting tube at the bottom of the mask component; a nebulizer at the bottom of the connecting tube; a processing tube at the bottom of the nebulizer; an oxygen delivery tube at the bottom of the processing tube; and a drug delivery tube on the processing tube. The drug delivery tube is generally Y-shaped. This invention, through the Y-shaped design of the drug delivery tube, provides a dual-channel system, allowing for one-to-one use and one-to-standby operation. Alternating use eliminates the need for the separate loosening of the old drug bottle, solving the problem that most spray oxygen delivery masks only have a single drug bottle attachment point, resulting in significant oxygen loss during bottle replacement and a cumbersome replacement process, leading to lengthy replacement times.
