AI Technical Summary

Technical Problem

Existing nasal fixation devices for indwelling tubes may compress the indwelling tube when the patient is lying down, and sweating on the bridge of the nose can reduce the adhesive effect of the tape, resulting in insufficient fixation.

Method used

The device employs a nose support rod and adjustment mechanism, and through the cooperation of the winding shaft and connecting belt, combined with the fixing effect of the wedge block and the top plate slot, it achieves precise and stable fixation of the indwelling tube; the synergy of the clamping block and the limiting spring prevents the indwelling tube from falling out and avoids excessive compression.

Benefits of technology

It achieves reliable fixation of the indwelling tube, avoids the shortcomings of traditional tape, ensures the stable position of the indwelling tube in the nasal cavity, prevents dislodgement and damage, and meets the strict requirements of medical care.

Abstract

The utility model relates to the field of medical care equipment, and discloses an indwelling tube nose fixing device which comprises two groups of nose supporting rods, a connecting rubber seat is fixedly connected between the two groups of nose supporting rods, an adjusting mechanism is arranged on the outer side wall of the nose supporting rod on the left side, and a fixing mechanism is arranged on the outer side wall of the nose supporting rod on the right side. Fixing assemblies are arranged at the bottom ends of the two groups of nose supporting rods, the adjusting mechanism comprises a fixing block, the inner wall of the fixing block is rotatably connected with a winding shaft, a connecting belt is wound on the surface of the winding shaft, and the inner wall of a rotating block is elastically connected with a wedge block through a reset spring. The length of the connecting belt can be flexibly adjusted according to the head circumference of different patients through the matching of the winding shaft and the connecting belt, and the device can be accurately and stably fixed at a proper position by virtue of the fixing effect of the wedge block and the clamping groove of the top plate, so that the device is attached to the head of the patient, and the two groups of nose support rods are attached to the nose bridge to support the indwelling tube.
