Description

Oropharyngeal airway

technical field

The utility model relates to the field of medical equipment, in particular to an oropharyngeal ventilation tube.

Background technique

Oropharyngeal airway is mainly used for patients with airway obstruction, tongue base falling back or more airway secretions to avoid blocking the airway and keep the patient's airway unobstructed. It can also be used for patients with epilepsy or convulsions to prevent biting the tongue Or the base of the tongue, the existing oropharyngeal ventilation tube usually includes a straight tube and an arc-shaped elbow connected to the straight tube. After the tube is successfully placed, the straight tube is the proximal end, close to the patient's mouth, and the arc-shaped elbow is the distal end , into the throat; insert a trachea or a suction tube or a fiberoptic bronchoscope into the oropharyngeal ventilation tube for inspection and treatment, to improve the ventilation effect or suck out secretions to keep the patient breathing smoothly.

When the patient is restless, unconscious or in the process of turning from coma to awake, he will feel the discomfort of foreign bodies in the oropharynx, which will cause the position of the oropharyngeal ventilation tube to move due to the innate physiological reflex (unconditioned reflex). If it is not righted in time, it is easy to cause airway obstruction again and endanger life.

Utility model content

The purpose of the utility model is to propose an oropharyngeal ventilation tube which can prevent the oropharyngeal ventilation tube from falling off and give an alarm when the oropharyngeal ventilation tube is shifted.

The utility model is realized by adopting the following technical solutions:

The oropharyngeal ventilation tube includes the main body of the oropharyngeal ventilation tube and a lip stopper. It is characterized in that: the upper and lower ends of the occlusal part are provided with stoppers, and the stoppers are provided with a concave area that can fix the pressure sensor, and the lip stopper is set to match the pressure sensor. The outside of the pressure sensor is connected to the buzzer. When the oropharyngeal airway is displaced, the pressure on the pressure sensor changes, triggering the buzzer to work.

As mentioned above, the inner wall of the occlusal part is provided with a matching metal support part to prevent the patient from crushing the oropharyngeal ventilation tube when exerting force.

As described, the lip block, the pressure sensor, and the block form an incisor occlusal groove, and the incisor occlusal groove is a rectangular groove, which can prevent the oropharyngeal ventilation tube from falling off after the teeth occlude.

As described above, a flexible protective layer is pasted on the bottom of the occlusal groove of the incisors to prevent saliva from contaminating the pressure sensor and protect the teeth.

The beneficial effects of the utility model are:

(1) The oropharyngeal ventilation tube described in the utility model is provided with a pressure sensor and a buzzer, which can detect the displacement of the oropharyngeal ventilation tube and give an alarm;

(2) The oropharyngeal ventilation tube described in the utility model is provided with a metal support part to prevent the oropharyngeal ventilation tube from being crushed due to excessive force when the patient occludes;

(3) In the oropharyngeal ventilation tube described in the utility model, the lip block, the pressure sensor, and the block form an incisor occlusal groove, which can prevent the teeth from coming off after occlusal.

(3) The oropharyngeal ventilation tube described in the utility model is provided with a flexible protective layer to prevent saliva from contaminating the pressure sensor, reduce friction with the occlusal groove of the incisors, and protect the teeth.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figures 1 and 2, the oropharyngeal ventilator described in the present utility model includes an oropharyngeal ventilator body 1, a lip block 2, and stoppers 4 are arranged on the upper and lower ends of the occlusal part 5, and the stoppers 4 are set to be fixed In the concave area of the pressure sensor 3, the lip block 2 is provided with a through hole matching the pressure sensor 3, and the outside of the pressure sensor 3 is connected to a buzzer; the inner wall of the occlusal part 5 is provided with a matching metal support part 7; the lip block 2. The pressure sensor 3 and the block 4 form an incisor occlusal groove 6, which is a rectangular groove; the bottom of the incisor occlusal groove is pasted with a flexible protective layer.

The use process of the utility model is as follows: after the oropharyngeal ventilator body is placed, the lip block is located outside the lips, the teeth are occluded in the occlusal groove of the incisors, and the pressure sensor is guaranteed to receive the occlusal force of the teeth. The existence of the occlusal groove of the incisors can prevent the displacement of the oropharyngeal ventilation tube. When the oropharyngeal ventilation tube is displaced in an unexpected situation, the bite force on the pressure sensor will change greatly, triggering the buzzer to work and alarm. Promptly straighten the oropharyngeal airway.

Of course, the above content is only a preferred embodiment of the present utility model, and cannot be considered as limiting the scope of embodiments of the present utility model. The utility model is not limited to the above-mentioned examples, and equal changes and improvements made by those skilled in the art within the essential scope of the utility model shall all belong to the scope covered by the patent of the utility model.
