Description

an oropharyngeal airway

technical field

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

Background technique

Oropharyngeal snorkel is a commonly used clinical medical aid. Clinically, oropharyngeal snorkel is mainly used for patients with back of tongue, airway obstruction, maintaining airway patency and epileptic convulsions. These patients are unconscious or irritable, which can easily lead to oropharyngeal ventilation. The trachea protrudes out of the mouth, causing respiratory obstruction again, which is life-threatening; some patients have more oropharyngeal or respiratory secretions, which can lead to respiratory obstruction and suffocation if they cannot be removed in time.

When the oropharyngeal airway is used, the front end needs to reach the base of the tongue or below, which is sensitive and the patient will spit the tube out unconsciously, and the exposed part including the flange is cross-fixed on both sides of the cheek with adhesive tape. It is easy to fall off and cannot be effectively fixed. When the catheter is not detected in time, it will cause the tongue to fall back, and the sputum cannot be coughed out in time, which increases the risk of suffocation. In addition, the adhesive tape is close to the skin and sticks to the patient's hair. And cause discomfort; even some people are allergic to tape, prone to allergic dermatitis or ulceration, thus aggravating the patient's condition.

Thirdly, after the oropharyngeal airway is used for about 3 hours, the oropharyngeal airway needs to be taken out to perform oral care on the patient. Therefore, there are some problems in the existing oropharyngeal airway, which cannot be used by patients who are unconscious or irritable.

Utility model content

In order to overcome the defects of the prior art, the utility model provides an oropharyngeal ventilation tube, which can effectively solve the shortcomings of the existing adhesive tape fixation, and provides an oropharyngeal ventilation tube with a simple structure and avoiding falling off. After successful, the fixation is stable, the cleaning of the oral cavity is convenient and fast, and the comfort is good.

The technical scheme solved by the utility model is: to provide an oropharyngeal ventilation pipe, which includes a ventilation pipe, a flange, a tooth pad part and a pharyngeal curved part, characterized in that the flange is connected to one end of the tooth pad part, and the The other end of the tooth pad part is connected with the pharyngeal curved part, the free end of the tooth pad part is detachably connected to the pharyngeal curved part, and the plug end of the pharyngeal curved part is sleeved on the plug end of the tooth pad part, wherein the flange A flange increasing part is provided, two ends of the flange increasing part are respectively provided with through holes, and a fixing band is pierced through the through holes.

Further, the fixing belt is an annular closed structure, and the fixing belt is an elastic non-slip elastic belt or a buckle body for adjusting the length is installed on the fixing belt.

The flange or the flange growth part is made of medical non-toxic polymer material by injection molding.

The said flange growth part can fit well with the face without irritation.

During use, the pharyngeal curved part and the tooth pad part of the oropharyngeal airway are placed in the patient's mouth, and then the fixing belt (or bandage) is passed through the through holes of the flanges on both sides of the flange growth part, because the fixing belt itself is a belt. The elastic non-slip elastic band or the fixing band is equipped with a buckle body for adjusting the length, which can be effectively fixed and avoid the moving and falling off of the oropharyngeal airway. It reduces the risk of suffocation caused by the patient's involuntary spit out of the catheter, and improves treatment satisfaction.

During use, when there is phlegm obstruction or oral care, it is not necessary to pull out the oropharyngeal ventilation tube from the patient's mouth, and the parts other than the tooth pad part (by the tooth pad part, flange, flange growth part) can be inserted through the plug. and the fixing belt) to be unplugged for cleaning, disinfection or oral care, which reduces the pain caused to patients by frequent unplugging and insertion of the oropharyngeal ventilation tube.

The beneficial technical effects of the utility model are as follows: the oropharyngeal ventilation tube has the advantages of simple structure, good stability, no irritation, convenient use, high comfort, easy cleaning and disinfection, and does not require frequent extubation and intubation to reduce the pain of patients.

Detailed ways

The principles and features of the present utility model will be described below with reference to the accompanying drawings.

As shown in FIG. 1 , the oropharyngeal ventilation tube includes a ventilation tube 3, a flange 2, a tooth pad part 4 and a pharyngeal curved part 1, and is characterized in that the flange 2 is connected to one end of the tooth pad part 4, so the The other end of the tooth pad part 4 is connected with the pharyngeal curved part 1 , the free end of the tooth pad part 4 is detachably connected to the pharyngeal curved part 1 , and the plug end of the pharyngeal curved part 1 is sleeved on the plug end of the tooth pad part 4 , wherein the flange 2 is provided with a flange increasing part, and the two ends of the flange increasing part 5 are respectively provided with through holes 6, and a fixing band 7 is pierced through the through holes.

In the process of use, the pharyngeal curved part 1 and the tooth pad part 4 of the oropharyngeal airway are placed in the patient's mouth, and then the fixing belt 7 (or bandage) is passed through the through holes 6 of the flanges on both sides of the flange growth part 5, According to the size of the patient's head, adjust the elastic non-slip elastic band or adjust the length of the buckle body for effective fixation, which avoids the movement and falling off of the oropharyngeal airway, reduces the risk of suffocation caused by the patient's unconscious spit out the catheter, and improves the Treatment satisfaction.

During use, when there is phlegm obstruction or oral care, it is not necessary to pull out the oropharyngeal airway from the patient's mouth. , the growth part of the flange and the fixing belt) are unplugged for cleaning, disinfection or oral care, which reduces the pain caused by pulling and inserting the oropharyngeal ventilation tube to the patient.

The above are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the present invention. within the scope of protection of the utility model.
