Abstract

A RESPIRATOR FOR THE PREPARATION OF A HYPOXIC AND HYPERCAPNIC RESPIRATORY MIXTURE, containing a bld. from a transparent material with a hole for the entrance and exit of the breathing mixture and a seal with a fixing device for mounting on the patient's head, characterized in that, in order to realize the possibility of obtaining a breathing mixture with different oxygen and carbon dioxide content, it is equipped with at least one A septum of transparent material with an opening, the opening for the entrance and exit of the respiratory mixture in the respirator case is located in the part furthest from the patient's face.

Description

eleven

The invention relates to medical technology, namely to devices for breathing hypoxic-hypercaptic mixtures, and can be used to train and restore breathing of athletes.

A respirator is known for preparing a hypoxic-hypercaptic breathing mixture containing a mixer made in the form of a rigid body, on one side of which there is an opening for exhaled air, and on the opposite side an opening for atmospheric air D.

However, this respirator has a complex structure, is not easy to use, has a large mass and. dimensions. .

A breathing mask for exhaled air is also known, consisting of a transparent body, open on one side, and a seal with a locking device for fastening on the head of the patient ZJ.

However, when using the known device without additional oxygen supply, the respiratory mixture delivered to the patient has a strictly defined content of oxygen and carbon dioxide. Obtaining respiratory mixtures with different contents of oxygen and carbon dioxide without additional supply of oxygen with the aid of this device is not possible. The purpose of the invention is to make it possible to obtain respiratory from a mixture with different contents of oxygen and carbon dioxide.

The goal is achieved by the fact that a respirator for preparing a hypoxic-hypercaptic breathing mixture, soda: a rusting body made of transparent material with an opening dp inlet and outlet breathing mixture and a sealant with a locking device dp mounted on the patient's head, is equipped with at least one transparent partition material with an opening, the opening for the entrance and exit of the respiratory mixture in the respirator case is located in the part furthest from the patient’s face.

The drawing shows a respirator for preparing a hypoxic-hyper capnic respiratory mixture, general view.

74043. 2

The respirator consists of a body 1, made of transparent material in the form of a rigid cylinder with a volume of 6-10 liters of sealant 2, made 5 in the shape of an oval face, and an elastic strap 3 for fastening the respirator to the patient's head. On the side wall of the mixer housing 1, an opening 4 with an area of 3-4 cm is made, which connects the internal cavity of the housing 1 with the atmosphere. Inside the cylindrical body 1, at least one transparent septum 5 with aperture 6 is installed, the partition divides the internal volume of the cylindrical body 1 into parts 7 and 8, and the opening 4 is located in the part 7 of the body 1 most distant from the patient's face.

The respirator is used as follows.

The respirator is worn on the patient's face and fixed on the head with an elastic strap 3.

When breathing during the reception of the procedure in the internal volume of the cylindrical body 1, the concentration of gases of the respiratory mixture in each cycle of the steady-state operating mode of the respirator fluctuates around the average values if if the volumes of cells 7 and 8 are equal to each other) depending on the depth of breathing and can be calculated using the following formula :

18.5% by volume of oxygen and 2.3% by volume of carbon dioxide, the sequential connection of two and three such cells gives the partial volume of oxygen and carbon dioxide in the inhaled air, respectively, 16.5 and

13.6% by volume of oxygen and 3.4 and 3.7% by volume of carbon dioxide.

The proposed respirator for preparing a hypoxic-hypercapnic breathing mixture is simple in its constructive attitude, reliable in operation, portable, safe, and non-treh311740434

It uses artificial sources of gaseous oxygen content and coal components, gearboxes, and control gas, which is necessary for replenishing devices, provides, in some cases, the use of respiratory mixture of the dimer, for example, in case of weak lightweight hypoxia and hypercapnia. no ventilation.
