Description

A multifunctional oropharyngeal airway suitable for oropharyngeal moisturizing and drainage 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

Oropharyngeal ventilation tube is a non-invasive ventilation tube commonly used in clinic. It is generally an oval hollow plastic tube with an "S" shape, including the flange, the tooth pad and the pharyngeal curvature. The intubation operation is simple and 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 can lead to oropharyngeal trauma, airway obstruction, tooth loss and other complications of intubation; and when indwelling is required, it is inconvenient to fix, easy to shift, and lose the tube, and various clinical suction and oxygen supply are available. , atomization, and airway humidification devices are mostly mismatched and cannot be connected, which affects the 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, tongue falling back, and upper airway obstruction. Indwelling oropharyngeal ventilation tubes are required to maintain airway patency. During the indwelling of the oropharyngeal airway, the patient's oropharynx is open and the mouth is open to breathe, resulting in dry mouth and airway, thick airway secretions and even the formation of sputum scabs that are difficult to expectorate or attract, which will further aggravate airway obstruction and respiratory tract inflammation. The patient's oropharynx is in an open state and is directly connected to the outside world. Dust, pollutants and even foreign objects in the air can directly enter the airway. At the same time, the patient's oropharyngeal secretions can be sprayed directly, causing environmental pollution and cross-infection. . In clinical practice, extra-oral wet gauze covering and intra-oral spraying are often additionally performed. The anti-fouling and moisturizing effects are difficult to guarantee, and the nursing workload is also increased.

In addition, due to the indwelling tube in the oral cavity, the oral secretions increase. When the patient is lying on the side, the oral and airway secretions will continuously flow out along the corner of the mouth, impregnating the patient's perioral and facial skin, contaminating the clothing, causing discomfort to the patient, and even It will cause skin inflammation and ulceration; if the above secretions cannot be drained or sucked in time, they may easily descend into the airway and cause 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 fluid intake and output for 24 hours to guide fluid therapy. The 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 of the critically ill patients suffer from disturbance of consciousness, or receive analgesic and sedative treatment, and it is inconvenient to express the indwelling oropharyngeal airway. deal with.

SUMMARY OF THE INVENTION

In order to solve the above problems, the present invention discloses a multifunctional oropharyngeal ventilation tube suitable for the moisturizing and drainage of the oropharynx of critically ill patients.
