Abstract

The invention relates to medical technology, namely to devices for creating therapeutic breathing mixtures. In order to maintain a given concentration of the drug substance during the inhalation process, the inhaler is equipped with a confuser 11 located in the pipe 5 of the water tank 1 and connected to the inlet tube 9 of the drug liquid tank 10. The lid 4 of the tank 1 has an outlet 13, inside which the outlet tube 12 of the container 10 for the medicinal liquid is coaxially disposed. 1 il.

Description

The invention relates to medical equipment, namely to devices for creating therapeutic respiratory mixtures.

An object of the invention is to maintain a predetermined concentration of a drug substance during inhalation.

The drawing shows a schematic diagram of a steam aerosol inhaler.

The inhaler contains a water tank 1 with a heater 2, a heat sink 3 and a cover 4. A divider 6 is attached to the pipe 5 for connecting the bottom of the tank 1 to the atmosphere 6. At the inlet of the pipe 5, there is a regulator 7 of the air passage resistance with divisions and a pointer 8. Inlet tube 9 of the container 10 for medicinal fluid is connected to the confuser 11 located in the pipeline 5. The output tube 12 of the vessel 10 is placed coaxially in the outlet pipe 13 of the cover 4.

On the outlet pipe 13 is a connecting element 14 with a check valve 15. 25

The inhaler works as follows.

Before the start of the procedure, a medicinal solution is poured through the confuser 11 and the tube 9 into the container 10, the necessary division 30 on the regulator 7 is combined with the pointer 8, which ensures a certain effort of inspiration of the patient, the temperature sensor 3 sets a certain temperature of the water in the tank. 35

When inhaling, the check valve 15 opens, a vacuum is created in the outlet pipe 13, air flows through the windows of the regulator 7 into the pipeline 5, leaves small bubbles through the divider 6, passing through a layer of water 40, it is heated, saturated with its vapor and enters the outlet pipe 13 . At the same time, air through the tube 9 enters the container 10, bubbles to the surface, mixes with 45 aerosols of the drug solution and through the tube 12 enters the nozzle 13. Humidified, heated air from the water bath and heated, saturated aerosols of the drug solution, the air from the tank 10 is mixed in the pipe 13 and through the connecting element 14 is inhaled by the patient. When inhalation ceases, the non-return valve 15 closes, preventing the selection of a medicinal solution and heated water. To prevent filling of the pipeline 5 with water, the divider 6 should be made of water-non-wettable material and have holes of a small amount.

In the process of inhalation, water vapor does not enter into the container 10 for the medicinal fluid, and the concentration of the drug substance remains unchanged, the content of drug substances in the inhaled air therefore also remains unchanged.

The application of the proposed design will increase the reliability of the inhaler and will facilitate the work of nursing staff.

Claims (1)
