Description

(54) DEVICE FOR THE INTRODUCTION OF GAS INTO THE CAVITY

tubes at the same time at both ends of the channel so that the gas is evenly distributed along the channel. In addition, different gases can be mixed in the channel. If the device is required to be connected with only one gas-supply tube, then one of the end links of the internal channel is closed with a plug 5. The device can also be used from the other end, i.e. it is expedient to introduce the device to the patient from any of its sides. Since the parts of the side walls 10 which are in contact with the face are flat, the device does not roll off the face of the patient.

Subject invention

Claims (2)

1. A device for introducing gas into the nasal cavity, containing a tube with an inner channel of the same diameter and perpendicular to its outer surface nostril cannulas, earrings for fixing the device on the patient's head, mounted on the ends of the tube, for the purpose of more convenient
placing the device on the face of the patient and excluding an arbitrary exit of the cannula from the nostrils, the wall of the middle portion of the tube on which the nostril cannulas are located is thinner than the opposite wall of this
In the same section, the thickness of the wall on which cannulas for the nostrils are located increases towards the peripheral ends, and the thickness of the opposite wall decreases towards the peripheral ends, the side walls are made with a uniform thickness and flat from the outside.
2. A device according to claim 1, characterized in that the coefficient of change of wall thickness is three.
