AI Technical Summary

Technical Problem

The existing humidifiers for medical oxygen delivery are fixed in height and angle, which affects the patient's comfort, and the catheter is easily dislodged when the patient moves.

Method used

A humidification device including a mounting sleeve, an adjusting rod, a rotating disk and a fixed clamping plate is designed. The height and angle can be flexibly adjusted by using the adjusting rod and the rotating disk in combination, and the catheter is fixed by a tightening screw head and an elastic clamping pad to prevent it from falling off.

Benefits of technology

The height and angle of the humidifier can be flexibly adjusted according to the patient's needs, which improves the patient's comfort and ensures that the catheter does not fall off when the patient moves, thereby stabilizing oxygen delivery.

Abstract

The invention discloses a humidifying device for medical oxygen delivery, and belongs to the technical field of medical oxygen humidification. By arranging a mounting sleeve, a fixed toothed plate, a fixed spring, an adjusting rod, a mounting top plate, a clamping spring and a rotating disc, the fixed toothed plate is clamped and fixed to the surface of a fixed rack, and the height of the mounting top plate is adjusted and fixed; when the direction of the rotating disc needs to be adjusted, two shifting rods are pushed to drive a fixing clamping rod to be separated from a fixing clamping groove, a second mounting sliding rod drives a second limiting plate to slide in a second mounting groove to extrude a clamping spring to deform, and the rotating disc is controlled to rotate at the top of a mounting top plate till the rotating disc rotates by a proper angle; a second limiting plate is jacked up to reset under the springback effect of a clamping spring by loosening a shifting rod, a second mounting sliding rod is driven to pull a fixing clamping rod to reset and be clamped into a corresponding fixing clamping groove, and therefore the direction of a rotating disc can be conveniently adjusted according to the use requirement, and the humidifying bottle is adjusted to the height and angle comfortable for a patient.
