Detailed ways

In order to describe the technical content of the present utility model more clearly, further description will be given below in conjunction with specific embodiments.

Please refer to Fig. 1 to Fig. 2, the device described in the improved multifunctional oropharyngeal airway device of the present invention includes a bite body 1, a fixing belt 2 and an oropharynx airway 5, and the bite body 1 is A cavity 3 is provided, the cavity wall of the cavity 3 is extended to form a bite member 6, and the oropharyngeal airway 5 is non-detachably connected to the cavity 3, so that the oropharynx The air passage 5 does not move with the movement of the tongue or teeth, and the two ends of the fixing band 2 are connected with the two sides of the mouthpiece body 1; in this embodiment, on the one hand, the patient's teeth bite the The mouthpiece 6 is fixed, so that the position of the mouthpiece 6 is fixed. On the other hand, the oropharyngeal airway 5 is connected to the cavity 3, presses on the patient's tongue surface, and extends to the patient. Oropharynx, so as to fix the patient's tongue, prevent the tongue from falling back, and fully open the airway.

In a preferred embodiment, it is characterized in that one or several channels 7 are arranged in the oropharyngeal airway 5, and a sputum suction tube, gastric tube or oxygen tube can be pierced in the channel 7, In this embodiment, the oropharyngeal airway 5 can be set as an oropharyngeal airway 5 in which multiple passages 7 exist simultaneously, so that different passages 7 can be inserted with medical tubes with different functions, for example, suction tubes, Oxygen tube etc., can realize a plurality of treatment functions simultaneously through one oropharyngeal airway 5, has reduced patient's misery and injury.

In a preferred embodiment, the two ends of the fixing belt 2 are provided with fixing parts 4 , and the fixing belt 2 is connected with the mouthpiece body 1 through the fixing parts 4 .

In a preferred embodiment, the outer contour of the mouthpiece body 1 matches the human facial contour.

In order to better illustrate the improved multifunctional oropharyngeal airway device of the present invention, in the first embodiment of the present invention:

The utility model is used for bronchoscopy. When the bronchoscopy enters through the oral cavity, it is necessary to bite the mouth open and fix the teeth and lips at one time, so as to avoid damage to the bronchoscope during the examination. However, after the bronchoscope enters the oral cavity, it is easily disturbed by the movement of the tongue in the oral cavity, and it is not easy to find the glottis. And the position of the bronchoscope after seeing the glottis is not easy to fix, and the bronchoscope cannot be sent into the trachea quickly and well. The front end of the improved multifunctional oropharyngeal airway 5 device of the utility model is provided with a bite body 1, which can fix the teeth and the oral cavity, and the rear part is fixed with an oropharyngeal airway 5, which can fix the tongue and expose the glottis well, so that Bronchoscopy makes it easier to see the glottis and enter the trachea, reducing the pain and damage of the patient. In addition, if there is a lot of viscous sputum in the patient's airway, the bronchial suction device is not easy to suck out the sputum. 5 A sputum suction tube or even a stomach tube is built into one side of the oropharyngeal airway 5 of the device, and enters the trachea for sputum suction under the guidance of a bronchoscope.

In the second embodiment of the utility model:

The utility model is used for helping obstructive sleep apnea (OSAHS) patients and chronic obstructive pulmonary disease (COPD) patients to open airways. OSAHS patients with body infection or COPD patients with acute exacerbation may experience coma, confusion, and elevated PCO2. At this time, non-invasive positive pressure ventilation should be used to provide respiratory support treatment. Such patients are prone to tongue drop and airway obstruction. At this time, keeping the airway unobstructed and making the non-invasive ventilator work is the key. In the prior art, the oropharyngeal airway 5 is used alone, but the oropharyngeal airway 5 cannot be fixed, and is easily displaced in the oral cavity, so the airway cannot be kept unobstructed. At this time, the improved multi-functional oropharyngeal airway 5 device can be used, and the bite body 1 at the front end of the device can be used to fix the oropharyngeal airway 5 in the oral cavity, so as to ensure the smooth flow of the airway, and the non-invasive ventilator can play a role in expelling Intrapulmonary CO2, rescue OSAHS and COPD coma patients.

In the third embodiment of the present utility model:

The utility model is used for intravenous anesthesia. Some operations with relatively small trauma, such as benign breast tumor surgery and painless bronchoscopy, require intravenous anesthesia, but do not require tracheal intubation. If a tongue suffix occurs during intravenous anesthesia in such patients, the airway is obstructed and normal ventilation will be very dangerous. In the past, the oropharyngeal airway 5 was used to ensure the unobstructed airway, but patients often unconsciously spit the oropharyngeal airway 5 out of the mouth or move the tongue to displace the oropharyngeal airway 5 so that it cannot function. The improved multifunctional oropharyngeal airway 5 device of the utility model can solve this problem very well. Its front end is a bite body 1, which can be fixed on the head so that the oropharyngeal airway 5 at the rear end does not shift. Keep the airway unobstructed. In addition, one side of the oropharyngeal airway 5 of the device can be connected with an oxygen pipeline to ensure sufficient oxygen supply for the patient without affecting the operation of the bronchoscope.

The improved multifunctional oropharyngeal airway device in this utility model is adopted, which can not only reliably fix the patient's teeth and tongue, but also reduce the pain and damage of the patient. One or several channels are arranged in the oropharyngeal airway , the passage is pierced with a sputum suction tube, stomach tube or oxygen tube, which can be used for bronchoscopy, helping patients with obstructive sleep apnea and chronic obstructive pulmonary disease to open the airway and intravenous anesthesia, with a simple structure , a wide range of applications.

The above-mentioned embodiments are preferred embodiments of this patent, and are not used to limit the scope of implementation of the present utility model. Those skilled in the art may make improvements, changes, combinations, substitutions, etc. without departing from the principle of the present utility model. All belong to the scope of protection required by the claims of the present invention.

In this specification, the invention has been described with reference to specific embodiments thereof. However, it is obvious that various modifications and changes can be made without departing from the spirit and scope of the present invention. Accordingly, the specification and drawings are to be regarded as illustrative rather than restrictive.
