Abstract

The utility model discloses a semi-integrated oxygen inhalation oropharyngeal airway, which comprises a straight pipe and an arc-shaped elbow connected with the straight pipe. Baffles are arranged around the front end of the straight pipe; There is an oxygen tube. The front end of the oxygen tube extends out of the front end of the straight tube. The end of the oxygen tube is closed. The oxygen tube at the arc bend is provided with more than 2 gas outlets, and the gas outlet faces the lumen of the arc bend. . The oropharyngeal airway of the utility model ensures unobstructed breathing, can supply oxygen with mixed flow at the same time, and reduces the stimulation area of the pharynx by more than 30%, thereby improving the patient's comfort.

Description

Half-body oxygen inhalation oropharyngeal airway

technical field

The utility model relates to a medical rescue device, in particular to a semi-integrated oxygen-absorbing oropharyngeal airway.

Background technique

The oropharyngeal airway is often used in the clinical rescue process, and it is necessary to use the oropharyngeal airway to keep unconscious patients, patients who are not fully awake during anesthesia, and patients who are not fully awake after anesthesia. The existing oropharyngeal airway does not have an oxygen inhalation channel, so it is impossible to inhale oxygen at the same time while ensuring unobstructed breathing, and the arched part of the curved elbow greatly stimulates the pharynx.

Utility model content

The purpose of the utility model is to provide a semi-integrated oxygen inhalation oropharyngeal airway which can ensure unobstructed breathing and can supply oxygen with mixed flow.

In order to achieve the above purpose, the technical solution of the utility model is: a semi-integrated oxygen inhalation oropharyngeal airway, including a straight pipe and an arc-shaped elbow connected to the straight pipe, and a baffle is arranged around the front end of the straight pipe ; wherein, the side in the tube is fixed with an oxygen tube, the front end of the oxygen tube stretches out of the front end of the straight tube, the end of the oxygen tube is closed, and the oxygen tube at the arc bend is provided with an air outlet, and the air outlet faces the arc The lumen of the elbow.

Preferably, there is a partial gap at the arch of the arc bend, the gap is one-third of the length of the arc bend, and by opening a gap at the arch of the arc bend, that is, the back, the arc bend can be reduced. For the stimulation of the pharynx, it reduces the stimulation area by more than 30%.

Preferably, the utility model has designed the oxygen supply technology. After adopting the above-mentioned structure, an oxygen tube is fixed on the side of the tube, and the front end of the oxygen tube extends outside the front end of the straight tube. The oxygen tube at the bend is provided with an air outlet to the lumen of the curved bend, so that the oropharyngeal airway not only ensures unobstructed breathing, but also supplies oxygen with the mixed flow of oxygen coming in from the oxygen tube and the air in the oropharyngeal airway.

detailed description

As shown in Figures 1, 2 and 3, the semi-integrated oxygen inhalation oropharyngeal airway of the present invention includes a straight pipe 1 and an arc-shaped elbow 2 connected with the straight pipe 1, and the front end nozzle of the straight pipe 1 is provided with Baffle plate 3; Oxygen tube 4 is fixed on the left and right sides in the tube, and the front end of oxygen tube 4 stretches out of the front end of straight pipe 1, and the end of oxygen tube 4 is closed, and oxygen tube 4 at arc bend 2 places is provided with Air outlet 41. At the arched place of the curved pipe 2, there is a part of the gap 21 on the back side, and the backside gap 21 is 1/3rd of the length of the curved pipe 2, reducing the contact area with the pharynx by more than 30%.

When the utility model is in use, the curved pipe 2 and the straight pipe 1 are stretched into the oropharynx, the baffle plate 3 is stuck outside the lips, the straight pipe is at the tooth pad, and the oxygen pipe 4 is externally connected to the oxygen supply device.

In the oropharyngeal airway of the present utility model, air enters from the straight pipe 1 and the curved pipe 2, and oxygen enters from the oxygen pipe 4 and comes out from the air outlet 41 communicating with the curved pipe 2 lumen to connect with the curved pipe 2. In this way, the oropharyngeal airway not only ensures unobstructed breathing, but also the oxygen coming in from the oxygen tube is mixed with the air in the oropharyngeal airway to supply oxygen. And by setting part breach 21 at arc bend 2 arches, breach 21 is 1/3rd of arc bend 2 lengths, reduces arch arc bend 2 to the stimulation of pharynx like this, makes patient feel more comfortable.

The above description is only the preferred implementation of the utility model, and of course the scope of rights of the utility model cannot be limited by this. It should be pointed out that any modification or equivalent replacement of the technical solution of the utility model does not depart from the technical solution of the utility model scope of protection.
