SU1255128A1 - Arrangement for supplying gas into nasal passages - Google Patents

Description

This invention relates to medicine and can be used to treat respiratory failure.

The purpose of the invention is to reduce respiratory gas losses and device trauma.

Fig. 1 schematically shows a device for supplying gas to the nasal passages, a general view; in fig. 2 - canal, longitudinal section; Fig. 3 shows a section A-A in Fig. 2 (gas supply and support tubes in cross section).

The device for supplying gas to the nasal passages contains the nasal cannulas 1 and 2 of the gas supplying tubes 3 and A with a movable coupling 5 and a flexible connector 6 made of wire.

Each cannula 1 and 2 contains an inner support tube 7 with a reinforcing element 8 made of flexible wire and an outer shell 9 of a pear shape in an expanded state. The connector 6 and the reinforcing elements 8 are made of a single flexible wire.

The device works as follows.

First, it is installed on the patient's head. For the connector 6, it is bent, setting the distance between the cannulas necessary for the patient. Bend the reinforcing elements 8, adjusting the angle and shape of the cannula 1 and 2 to the patient. Move the clutch 5 through the tubes 3 and 4 for fixing the device on the head.

Respiratory gas is supplied to tubes 3 and 4. The sheath 9 expands in the shape of the nasal passages, and the gas enters them through the supporting tubes 7.

When the gas supply is temporarily stopped, the cannulas are not removed, since the sheath 9 falls off, leaving a gap for breathing.

Suction catheters can be inserted into the nasal passages also without removing the cannulas 1 and 2. At the same time, the sheath 9 seals the catheters and eliminates breathing gas leakage.
