Description

An oxygen-absorbing oropharyngeal airway for digestive endoscopy

technical field

The utility model belongs to the technical field of medical devices for auxiliary detection of digestive endoscope, in particular to an oxygen-absorbing oropharyngeal airway for digestive endoscope.

Background technique

Painless digestive endoscopy is more and more widely used in the examination of digestive organs. At present, a large number of painless oral digestive endoscopic examinations or operations are performed under general anesthesia without endotracheal intubation under the condition of nasal catheter oxygen inhalation. Intravenous anesthesia can be used instead of endotracheal intubation.

However, in the process of digestive endoscopy, oxygen inhalation through nasal cannula is inefficient and ineffective, which makes patients prone to hypoxemia and endangers their lives. At the same time, in the state of intravenous anesthesia without endotracheal intubation, the patient is prone to fall back of the tongue and cause airway obstruction, resulting in fatal accidents such as respiratory failure and cardiac arrest.

The effective measure to prevent and treat tongue relapse lies in the application of oropharyngeal airway or nasopharyngeal airway. However, the existing oropharyngeal airway cannot pass through the digestive endoscope because of its too small caliber and cannot provide stable and reliable airway during digestive endoscopy. Oxygen inhalation conditions are difficult to apply to digestive endoscopy.

In order to solve the above technical problems, the Chinese Utility Model Patent No. CN 205460272U provides a weakly stimulating oropharyngeal airway for digestive endoscopy. In order to reduce the irritation to the uvula, the central sulcus of the tongue is elevated at the same time. One side of the airway body is a semicircular ventilation groove, and the other side is a circular endoscopic channel. The lip protection sheet is set, and the ventilation groove and the endoscopic channel pass through the dental pad and the lip protection sheet.

However, the shape of the patented airway is similar to the traditional arc-shaped oropharyngeal airway. After placement, the tip of the tongue will move forward or to the other side, thereby blocking the insertion and operation of the digestive endoscope. For example, violent operation will damage the tongue. In addition, the ventilation groove in this patent is a semicircular open channel. If you want to inhale oxygen, you need to place an additional oxygen pipeline. However, most of the oxygen channels currently used in clinical practice are nasal catheters, which are easy to block the mouth after being placed, and are not suitable for use in the mouth. Oxygen inhalation, at the same time, the semicircular open channel is easy to leak oxygen, and the oxygen inhalation efficiency is low. When the patient's respiratory depression occurs, it cannot be directly connected to the breathing balloon for positive pressure ventilation.

Utility model content

The utility model is developed to solve the above-mentioned problems, and provides an oxygen-absorbing oropharyngeal airway for digestive endoscopes, which is convenient for the insertion operation of the digestive endoscope and convenient for ventilating oxygen at any time.

A connecting tube that protrudes from the body of the pharyngeal airway. Wherein, the tail end of the oxygen channel is provided with an oxygen main ventilation hole, and the shape of the main body of the oropharyngeal airway is the same as that of the oxygen channel, both of which are hollow S-shaped.

Preferably, in the oxygen-absorbing oropharyngeal airway for digestive endoscope provided by the utility model, the oropharyngeal airway passes through a channel and is provided with a card slot for clamping the main body of the oropharyngeal airway, so as to facilitate the adjustment of the insertion depth according to the patient. Fix the tongue below the S to prevent the tongue from falling backwards.

Preferably, in the oxygen-absorbing oropharyngeal airway for digestive endoscope provided by the utility model, the lip protection pad is made of medical silica gel.

The texture of medical silicone is relatively soft, which will not cause excessive pressure on the patient's tongue, and can fit tightly with the tongue to protect the tongue.

Preferably, in the oxygen-absorbing oropharyngeal airway for digestive endoscope provided by the utility model, a plurality of side ventilation holes arranged up and down are arranged on the side wall of the lower end part of the oxygen channel.

In the utility model, the opening of the main oxygen vent hole at the tail end of the oxygen channel is directly aligned with the glottis, which is conducive to oxygen inhalation and improves the efficiency of oxygen inhalation, and the oxygen side vent hole on the inner side wall is not easily blocked by the tissue in the oral cavity. When the opening of the main vent is blocked, the vent on the oxygen side can also supply oxygen to ensure patient safety.

Preferably, in the oxygen-absorbing oropharyngeal airway for digestive endoscopy provided by the utility model, the outer mouth of the airway is a standard interface of a medical breathing balloon, and when the patient's respiratory depression or blood oxygen saturation drops, the breathing balloon can be connected Positive pressure ventilation to maintain the patient's blood oxygen saturation and ensure the safety of the patient's life.

Function and effect of utility model

The oxygen-absorbing oropharyngeal airway for digestive endoscopy provided by the utility model has the following technical effects:

First of all, because the oxygen channel is embedded in the main body of the oropharyngeal airway, the main body of the oropharyngeal airway and the oxygen channel have the same shape, both of which are hollow S-shaped. This S-shaped oropharyngeal airway can effectively fix the tip of the tongue and the tongue body, Not only is it beneficial to endoscopic operation, but it can also effectively prevent the tongue from falling backwards and avoid hypoxemia caused by blocking the airway. At the same time, it also solves the problem that the tip of the tongue will move forward or move to the other side after the traditional arc-shaped oropharyngeal airway is placed, thereby blocking the insertion and operation of the digestive endoscope.

Secondly, since the external connection of the oxygen channel is provided with a connecting tube, the connecting tube can be directly connected to oxygen, so that the oxygen can directly ventilate the patient through the oxygen channel, which is fast and convenient to use; it can also be connected to equipment such as a carbon dioxide monitor to monitor the patient's breathing in real time, and timely Detect breathing changes to ensure the safety of patients.

Therefore, when carrying out digestive endoscopy or operation under intravenous general anesthesia, the new oropharyngeal airway can fix the tongue under the airway, and at the same time, oxygen inhalation or respiratory monitoring can be carried out through the oxygen channel, which ensures the safety of patients. Ventilation safety, thereby ensuring the safety of patients.
