Description

A multi-functional oropharyngeal ventilation tube suitable for moisturizing and drainage of oropharynx in critically ill patients

technical field

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

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 of the devices for airway, atomization, and airway humidification do not match and cannot be connected, which affects secretion suction, oxygen supply, atomization, and humidification effects, and also increases the nursing workload of airway management.

Severely ill patients are often accompanied by disturbance of consciousness, backward tongue, and upper airway obstruction, and an oropharyngeal ventilation tube needs to be indwelled to keep the airway unobstructed. During the indwelling period of the oropharyngeal ventilation tube, the patient's oropharynx is open and the mouth is open to breathe, resulting in dry mouth and airway, thick airway secretions and even formation of phlegm scabs that are difficult to cough up or attract, which will further aggravate airway obstruction and respiratory inflammation. The patient's oropharynx is in an open state and directly communicates with the outside world. Dust, pollutants and even foreign objects in the air can directly enter the airway. At the same time, the patient's oropharynx secretions can be directly splashed out, causing environmental pollution and cross-infection . Clinically, additional nursing operations such as covering the mouth with wet gauze and spraying inside the mouth are often performed. The antifouling and moisturizing effects are difficult to guarantee, and the nursing workload is also increased.

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 will cause skin inflammation and ulceration; if the above secretions cannot be drained or attracted in time, they will easily go down and enter the airway by mistake, leading to aspiration, suffocation and aspiration pneumonia. 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.

Contents of the invention

In order to solve the above problems, the present invention discloses a multi-functional oropharyngeal ventilation tube suitable for moisturizing and drainage of the oropharynx of critically ill patients. Oropharynx and other skin and mucous membranes; it can be connected with the existing clinical continuous suction (measureable drainage), oxygen supply, atomization, and airway humidification devices to ensure suction, oxygen supply, atomization and airway humidification while achieving a sealed mouth.
