Abstract

The invention relates to medical technology, namely to devices for creating therapeutic breathing mixtures. To improve the quality of pre-sterilization treatment and ease of operation, the tubes 6 and 5 of the fluid and air supply are respectively installed so that their ends are located in the lid cavity, while the output end of the tube 5 is bent at an angle of 40-60 ° to the vertical axis of the inhaler. 2 Il.

Description

FIG. 2

The invention relates to medical technology, namely to devices for the creation of therapeutic airways.

The purpose of the invention is to increase the pre-sterilization treatment and ease of operation.

On fmg. 1 shows an inhaler, incision; in fig. 2 - body, cut.

The inhaler contains a balloon 1 of elastic, resilient material designed to create an overpressure. At the bottom of the cylinder valve 2 is installed, providing air supply only inside the cylinder. In the upper part of the container, the housing 3 is installed so that a part of the housing is above the balloon. Due to the elastic properties of the material of the container, the connection between the body and the cylinder is tight, which prevents air from leaking through this connection. The body 3 is made of glass. Inside the case, a sprayer 4 with tubes 5 and b is installed in its bottom by means of a paired connection, for supplying air and medicinal fluid, respectively. These tubes are rigidly interconnected and protrude 3-6 mm above the upper edge of the casing so that their ends are located in the inner cavity of the lid 7 with the outlet. The outlet end of the air supply tube 5 is curved at an angle of 40-60 ° to the vertical axis of the inhaler. The tube 6 for supplying the medicinal fluid is made without bends, its lower end is located at the inner surface of the housing 3 at the interface of its bottom and side walls. The nozzle of the cover 7 is located at an angle of 40-60 ° to the vertical axis of the housing 3 and coincides with the axis of the bent end of the air supply tube 5. The nozzle of the lid 7 is closed by the stopper 8. The lid 7 and the stopper 8 are connected to each other by means of a flexible element 9, Hanpwf iep THREAD. The connection of the lid 7 to the ° plug 8 is airtight. The lid 7 assembled with the stopper 8 serves as a measuring vessel at. filling the inhaler with drug liquid. E 1 a cover of 7 is prepared and samples of CP 8 can be made from any elastic material, for example, from plastic. The cylinder 1 and the cover 7 with the plug 8 in assembled form, besides the indicated functions, are at the same time the protective cover for the glass case 3 of the inhaler. .

Inhaler works as follows.

The cover 7 together with the stopper 8 is removed from the case 3 of the inhaler. In the cover 7 pour the necessary medicinal liquid. At the same time, the mat 7 and the plug 8 are assembled. Then medicinal

the liquid is poured into the housing 3 and the lid 7 is put on the housing 3. After that, the stopper 8 is opened and the sprayed medicinal liquid is supplied through the nozzle of the lid by periodically compressing the balloon 1.

The dispersion of the sprayed medicinal fluid and its flow rate is regulated by turning the lid 7 around the axis,

The maximum value of the sprayed particles of the drug liquid and its flow takes place when the axis of the nozzle of the lid 7 coincides with the axis of the bent part of the air supply tube 5. Visually, this moment is controlled by a mark 10 located on the cylinder 1. Changing the location of the nozzle of the cover 7- with the axis of the bent part of the air supply tube 5 provides the change

the dispersion and consumption of the sprayed medicinal fluid, which is necessary in the treatment of various respiratory organs.

After the end of use with the inhaler, the nozzle of the cover 7 must be closed with a stopper 8. In this position, the wearing of the inhaler is ensured. However, he can be in any position.

Modifying the design of the inhaler by protruding the ends of the tubes for supplying the medicinal fluid and air over the upper edge of the housing 3–6 mm in the cavity of the lid 7 and making the tube for supplying the medicinal fluid without bends

in the upper part, capillary openings of tubes 5 and 6 can be cleaned for supplying medicinal liquid and air (with cover 7 removed) in the event that foreign particles interfere with them

movement of fluid and air, and increase the reliability of the inhaler itself. Making the lid with a nozzle located at an angle of 40–60 ° to the vertical axis of the inhaler, coinciding with the axis of the bent end of the tube 5 for feeding air, increases the convenience of operation both during operation and during sterilization,

Formula of invention

Inhaler, comprising a housing with tubes for supplying fluid and air, a discharge point and a cover with an outlet nozzle, the axis of which coincides with the axis

the outlet part of the air supply tube, which is characterized by the fact that, in order to improve the quality of presterilization treatment and ease of operation, the liquid and air supply tubes are installed as follows. that their ends are located in the inner cavity of the lid, while the outlet end of the air supply tube is curved. At an angle of 40-60 ° to the vertical axis of the inhaler.
