Description

The proposed solution relates to medical equipment and can be used in departments for newborns of maternity hospitals, in intensive care units and intensive care of children's hospitals for children with any respiratory-heart failure, including heart defects.

Known devices in the form of pressure chambers for intensive care, creating an atmosphere of high pressure in a sealed chamber. For example, according to the patents of the Russian Federation No. 2061451, 2032394, 2023441, 52696, 50411, A61G 10/02.

The disadvantages of the known devices is that all medical pressure chambers work only with dry oxygen, a long stay in them leads to oxygen poisoning.

Known devices of incubators (kuvez) in which it is possible to stay for a long time in a humid atmosphere saturated with oxygen. For example, according to the patents of the Russian Federation No. 2103034, A61G 11/00, 2077299, A61N 5/06.

The disadvantages of the known solutions is that in them for a number of reasons, for example, due to lack of pressure, due to lack of tightness, 100% saturation with moisture and oxygen is not achieved, which slows down the process of oxygen dissolution in blood plasma.

The problem arises of creating a device that combines the advantages of pressure chambers and couveses. By the similarity of design features, the closest to the claimed is the intensive care unit according to the patent of the Russian Federation No. 2226289, A61G 11/00.

The well-known couvez contains a chamber inside which systems are installed: air humidification, forced air circulation, oxygen supply and heating, phototherapy, as well as instruments for controlling humidity, temperature and oxygen concentration.

The disadvantages of the known couvez include the fact that the chamber is not tight, the air-oxygen mixture supplied inside the chamber does not have a forced discharge and diverges through various openings, therefore it is impossible to create an oxygen concentration of 100% in it, the maximum possible oxygen level in this design is 80% . It is also impossible to provide 100% humidity, as in a couveuse, the air-oxygen mixture passes into the chamber through a container of water, being moistened, but not sprayed, and dried by a phototherapeutic system arranged at the top of the chamber containing blue light bulbs. In this case, oxygen and air are not dosed.

The technical result of the proposed solution is to achieve 100% oxygen saturation of the air inside the chamber and its 100% humidity, which will allow for long-term natural respiratory function of the lungs of children with acute respiratory-heart failure syndrome.

The technical result is achieved in that the hyperbaric oxygenation complex contains a movable chamber with a lodgement, equipped with oxygen-air mixture supply systems, an air humidification system inside the chamber and a chamber heating system, characterized in that the chamber is sealed, the air humidification system is made in the form of a drug injector the mixture that is installed at the head of the bed at the level of the lodgement, and in front of the nozzle of the injector a reflecting screen is installed, the oxygen-air mixture supply system flax in the form of a compressor and an oxygen cylinder connected to a rotameter for dispensing and mixing the mixture, which in turn is connected to the receiver with a pressure regulator, an oxygen-air mixture supply hose and a valve to relieve pressure in the upper wall of the chamber, and the heating system is made in the form an electric boiler connected by a pipe through the end of the chamber with a lodgement, and additional heating tubes mounted on the walls of the chamber or made in the form of an electric heating plate of one of the walls of the receiver. The tightness of the chamber is ensured by its implementation from thick plastic, while from one end the chamber is sealed with metal, and from the other it is made in the form of a door tightly adjoining due to rubber gaskets.

The implementation of the chamber sealed with the proposed system of supplying oxygen-air mixture under pressure will allow you to create an oxygen concentration of 100% in the chamber, you can dose the percentage of oxygen up to 5-10% (depending on the degree of respiratory-heart failure), the increased pressure contributes to the dissolution of oxygen in blood plasma. 100% humidity is achieved by fine atomization with an injector. To ensure heating, it is possible to heat using heated water or using heated air. In a humid warm atmosphere of high pressure, the child may be depending on the state for 1-7 days, while his breathing is always independent, and not forced, as with artificial ventilation, leading to spasm of the vessels of the brain and kidneys.

Figure 1 shows a general view of the hyperbaric oxygenation complex. The complex consists of a movable chamber 1, the walls of which can be made of thick transparent plastic, one of the ends 2 of the chamber 1 is made in the form of a door hermetically sealed by rubber gaskets, and the other is sealed with metal. Inside the chamber, there are 3 control devices for microclimate parameters: a thermometer, a hygrometer, a manometer and an oxygen monitor on the relief valve 9.

The chamber is equipped with an oxygen-air mixture supply system, which consists of: a compressor 4 and an oxygen cylinder 5 connected to a rotameter 6, in which the percentage of oxygen and air in the mixture is set in liters / minute, in certain cases only oxygen is supplied through the rotameter 6 or just air. The compressor 4 is connected to the receiver 7, which is equipped with a pressure sensor inside and a pressure regulator on top. To prevent pathogenic flora from entering the chamber, replaceable filters are installed in front of the receiver 7. The oxygen-air mixture is supplied to the chamber through a hose 9, and a valve 10 is provided to relieve pressure in the chamber 1.

The air humidification system inside the chamber is made in the form of an injector 11 with a drug mixture, which is installed at the head of the bed at the level of the lodgement 12, and a reflecting screen 13 is installed in front of the nozzle of the injector. For infusion, an infusion of herbs or saline solution similar in composition to blood plasma is used. Contributing to liquefaction of sputum, improving drainage function of the lungs and expanding bronchi, bronchioles and alveoli.

With a constant depressurization, the inside of the chamber will be cool, therefore, it is provided for by the heating system of the chamber, in the form of an electric boiler 14 connected by a pipe through the end of the chamber 1 with a lodgement 12 and additional heating tubes fixed along the chamber walls. In this case, it is possible to perform a heating system in the form of a receiver 7 connected to a rotameter 6, one wall of which is made in the form of an electric heating plate. It is possible to install a dark filter on top of the camera to reduce annoying daylight.

The work of the complex is as follows.

The hyperbaric oxygenation complex is intended for children with severe acute respiratory heart disease syndrome, from the time of birth to 3-5 years old. Such children can be in the device’s cell for 1 to 3-7 days. The child is placed on a lodgement and attached to the body are ECG sensors, heart rate, body temperature, respiratory rate, and the percentage of oxygen in the blood. Sensor readings are displayed on monitors. Children are taken out of the chamber every 4-6 hours for the introduction of intravenous drugs, feeding, changing clothes.

The proposed device uses high pressure to 0.2-0.3 atmospheres, but if necessary, it can be brought up to 1.0 atmosphere. For example, we create a constant pressure in the receiver to 5-10 atmospheres, adjust the receiver to 0.5-1.0 atm., And send the oxygen-air mixture further into the chamber in a constant mode of 1.0 atm. As soon as the pressure in the receiver dropped below 3.0 atm. the compressor automatically turns on and again pumps oxygen and air into the receiver, and the oxygen-air mixture constantly leaves it in the set mode.

First, the first 10-30 minutes, pure and necessarily moistened 100% oxygen is supplied, then, as the condition improves (skin pinking, better breathing, better heart function, lower respiratory rate), air heated in receiver 7 from the compressor is supplied and oxygen is diluted first to 70%, then up to 50%. This 50% mode is maintained for the first 4-6 hours, when it comes time to remove the child from the camera. Before removing the child, the chamber is blown only with air at zero pressure for 3-5 minutes to adapt the child to breathing outside the chamber. Usually, within a day (less often within three days, depending on the patient’s condition), the percentage of oxygen is brought up to 15-25% and, if possible, is removed altogether with a minimum pressure of not more than 0.3 and not lower than 0.1 atmosphere for the remaining treatment period . Upon reaching stable results characterizing the state of the child, as a state of moderate severity, staying in the air, outside the cell, increases, first up to 30-45 minutes, then up to 60-90 minutes and, if the condition does not change after 90-120 minutes, intense oxygen exposure to pressure in the chamber can be stopped, but keep the chamber ready for another 1-2 days.
