Multifunctional oropharynx breather pipe suitable for moisturizing and drainage of oropharynx of critical patient

Abstract

The invention provides a multifunctional oropharynx breather tube suitable for moisturizing and drainage of oropharynx of a critical patient, which comprises an oropharynx breather tube main body, the oropharynx breather tube main body is composed of an extension tube, a tooth cushion tube and a pharynx bending tube which are sequentially connected from top to bottom, and the upper end of the oropharynx breather tube main body is sleeved with a lip protection shield, two liquid guide holes which are symmetrically arranged left and right are formed in the lip protection shield, liquid guide pipes are installed in the liquid guide holes in a matched mode, and a U-shaped blocking pad is arranged on the bottom face of the lip protection shield. The catheter is exquisite in design and diversified in function, can be firmly fixed after being indwelled, and avoids damaging skin mucous membranes such as teeth, lips and tongues, oropharynx and the like of a patient; the oral cavity sealing device can be connected with existing clinical continuous suction (capable of metering drainage volume), oxygen supply, atomization and airway humidification devices, the effects of suction, oxygen supply, atomization and humidification are guaranteed while the oral cavity is sealed, an oropharynx breather pipe and an airway are kept unobstructed, and secretions in the oral cavity and the airway are accurately metered; the patient comfort is improved, the clinical workload of airway management is reduced, and the efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a multifunctional oropharyngeal ventilation tube suitable for moisturizing and drainage of the oropharynx of critically ill patients. Background technique [0002] The oropharyngeal ventilation tube is a commonly used non-invasive ventilation tube in clinical practice. It is generally an oval hollow plastic tube with an "S" shape, including the flange, the dental pad and the pharyngeal curvature. The tube is easy to operate, can quickly open the airway, establish a temporary artificial airway, prevent the tongue from falling back, ensure smooth breathing, and save lives. However, there are the following problems, which will lead to oropharyngeal trauma, airway obstruction, tooth loss and other complications of catheterization; and when indwelling is required, it is inconvenient to fix, easy to shift, detachment, and various existing clinical suction, oxygen supply Many ...

AI Technical Summary

Problems solved by technology

Clinically, extra oral wet gauze covering, oral spray and other nursing operations are often performed. It is difficult to guarantee the effect of antifouling and moisturizing, and it also increases the workload of nursing.

[0004] In addition, due to the indwelling pipeline in the oral cavity, the oral secretions increase. When the patient is lying on his side, the oral and airway secretions will continuously flow out along the corners of the mouth, impregnating the patient's perioral and facial skin, contaminating the clothes, causing discomfort to the patient, and even It can cause skin inflammation and ulceration; if the above-mentioned secretions cannot be drained or attracted in time, they can easily go down and enter the airway by mistake, leading to aspiration, suffocation and aspiration pneumonia in patients

Continuous cleaning and suction of secretions greatly increase the nursing workload; moreover, critically ill patients need to accurately record the 24-hour fluid intake and output to guide fluid therapy. Lost oral and airway secretions cannot be measured, which will lead to fluid measurement errors and affect the accuracy of fluid therapy sex

In addition, most critically ill patients have impaired consciousness, or receive analgesic and sedative treatment, and indwelling oropharyngeal ventilation tubes are inconvenient to express, etc. Oropharyngeal ventilation tubes compress the lips, teeth, tongue, and oropharynx, which can easily cause pressure injuries, but cannot be detected and intervened in time deal with
