(Patent in the Russian Federation No. 2722432, published on May 29, 2020).

A device for percussion ventilation of the lungs is known, configured to supply a flow of pulsating gas supplied to the elongated body of the breathing head at its proximal end. The device includes a reciprocating injection mechanism, movably mounted in the channel of the breathing head, moving distally due to pulsating gas, assisted by a Venturi-type nozzle, which draws the atomized aerosol from the dependent plenum and the nebulizer attached under the dependent chamber. (US Patent No. 11324914, published 05/06/2020).

The technical result of the proposed technical solution is to increase the safety of the intrapulmonary percussion ventilation procedure.

Increased safety of the procedure is achieved mainly due to the possibility of installing the device, in particular the container, on a flat surface without interrupting its operation, due to the possibility of connecting to one device that controls the operation of the device as a whole, due to the possibility of organizing an ergonomic working environment during therapy , eliminating the risk of unintentionally touching the components of the device, due to the possibility of repeated sterilization of the device without the risk of damage to its components with subsequent trauma.

The claimed technical result is achieved in that the device for intrapulmonary percussion ventilation includes a housing having an input for connection to the device for intrapulmonary percussion ventilation to supply an air flow into the corresponding channel in the housing, connected to a mouthpiece at the air flow outlet; the housing has a diffuser for passage of the air flow, expanding towards the flow outlet into the mouthpiece, and a channel for the exhaled flow with an outlet in the housing, not communicating with the channel for air supply, the housing is connected to the container for the medicinal product, while the channel for supplying air and the cavity of the container are made communicating, with the possibility of supplying the medicinal product into the channel for supplying air, the container for the medicinal product has an inlet for connecting to an apparatus for intrapulmonary percussion ventilation for supplying air into the container, while the inlet for supplying the medicinal product into the container is made in a lid connected to the upper part of the container, and the lower part of the container body is located in one horizontal plane.

A housing having an inlet for connecting to a device for intrapulmonary percussion ventilation of the lungs for supplying an air flow into the corresponding channel in the housing, inside of which there is a diffuser for the passage of the air flow, expanding towards the outlet of the flow into the mouthpiece, is necessary for the implementation of a device for intrapulmonary percussion ventilation of the lungs according to the target purpose. The internal design of the housing is characterized by the presence of a breathing circuit, which is an air flow converter in volume and pressure, and can provide intermittent percussion ventilation of the patient's airways (small tidal volumes with high flow rate and low pressure). Intermittent ventilation can be provided, in particular, by means of a piston injection shuttle installed in the housing, moved distally by pulsating gas. A channel for the exhaled flow with an outlet in the body, not communicating with the channel for supplying the air flow, is necessary to ensure the possibility of removing the exhaled flow through the body itself, without the need to remove the mouthpiece, while excluding its mixing with the supplied air, which may affect the safety of the procedure. procedures.

An important difference is that the body of the device and the lid of the container, connected to its upper part, have inputs for connection to the device for intrapulmonary percussion ventilation for supplying air flows, as well as the location of the lower part of the container in the same horizontal plane. This design characterizes the claimed device with the ability to be placed on a horizontal plane, which eliminates the risk of it tipping over or falling, which could affect the correctness of the procedure, in particular, the concentration of the drug supply, the speed and volume of air flows, and so on, and also allows for therapy independently, without the involvement of medical personnel. In addition, this design of the device allows the entire system to be compactly placed on one working surface, eliminating the need to use additional equipment for fixing the device components, in particular for hanging, which also provides the ability to safely place the patient in a comfortable sitting position, facilitating intrapulmonary therapy with stable parameters of air supply, aerosol. It is more preferable that the described inputs be made on one side of the device, in order to be able to use direct connection cables that provide a continuous supply of flows with the parameters specified according to the procedure protocol.

The cylindrical design of the container, due to the smoothness of the walls, makes it possible to use the full volume of the drug contained in it, which additionally characterizes the device with the safety of the procedure, eliminating the risk of incomplete delivery of the prescribed dose of the drug.

Making the air flow supply inlet into the container and the air flow supply inlet into the housing in the form of elements of phytic connections facilitates the possibility of effective sterilization of these components, as well as the ability to quickly connect and remove the corresponding tubes, which in general is an advantage for safe and comfortable therapy and operation of the device , if necessary, for example, in the event of emergency situations or deterioration in health, allows you to quickly disconnect or connect it.

The inventive technical solution is further illustrated using Figure 1, which shows a general view of the device for intrapulmonary percussion ventilation.

The following elements are indicated by numbers:

building 1);

inlet (2) for supplying air flow;

mouthpiece (3);

container (4) for a medicinal product;

inlet (5) for supplying air flow to the container (4);

outlet (6) of the channel for the exhaled flow.

Below, with reference to the figures, a preferred embodiment of the claimed device is described.

A device for intrapulmonary percussive ventilation (also called a breathing head) includes a housing (1) having an inlet (2) for connection to an apparatus for intrapulmonary percussive ventilation for supplying an air flow to the corresponding channel in the housing (1) connected to a mouthpiece ( 3) at the air flow outlet.

The housing (1) contains a diffuser for the passage of air flow, expanding towards the flow outlet into the mouthpiece (3). The diffuser is preferably a Venturi tube.

The housing (1) also has a channel for the exhaled flow with the outlet of the channel in the housing (1), not communicating with the channel for supplying the air flow.

The housing (1) is connected to the container (4) for the medicinal product, and the channel for supplying the air flow and the cavity of the container (4) are made communicating, with the possibility of supplying the medicinal product into the channel for supplying the air flow. The container (4) preferably includes elements for delivering the drug in aerosol therapy mode (nebulizer).

The container (4) for the medicinal product has an inlet (5) for connection to an intrapulmonary percussion ventilation device for supplying an air flow to the container (4), made in a lid connected to the upper part of the container (4).

The lower part of the container body (4) is located in one horizontal plane. In other words, the lower part of the housing may have a flat bottom, or a peripheral part in the form of an outline of the container (4), located at a level lower than the remaining parts of the container (4), allowing the container (4) to be installed on a horizontal plane, for example, on a table. Preferably, the container body (4) is cylindrical.

In a preferred embodiment, the inlet (5) for supplying air flow to the container (4) and the inlet (2) for supplying air flow into the housing (1) are made in the form of fitting connection elements.

Preferably, the inlet (5) for supplying air flow to the container (4) and the inlet (2) for supplying air flow into the housing (1), as well as the housing (1) and the container (4), are made of plastic material, allowing quick and effective sterilization of equipment, without the risk of unintentional damage.

The claimed device for intrapulmonary percussion ventilation works as follows.

A device for intrapulmonary percussive ventilation is connected to a device for intrapulmonary percussive ventilation, which provides an air flow with specified parameters (speed, pressure), providing a nebulation mode that monitors breathing parameters through sensors that can be installed in the device body. The corresponding tubes of the device are connected to the inputs (2), (5) to supply air flows.

During therapy, an intermittent air flow and an air suspension of the drug are supplied under pressure to the patient’s lungs, mixing in the corresponding channel in the body (1) of the device.

By directing percussive volumes of air into the lungs, a constant wedging pressure is maintained to stabilize the airways, allowing high-velocity airflow to penetrate the airways and enhance the mobilization of endobronchial secretions. During therapeutic percussion, the built-in nebulizer (container) creates an intense aerosol flow, which makes it possible to reduce the adhesive and congestive forces of the secretion located in the lungs, further increasing the safety of the procedure and the use of the claimed device, facilitating therapy in general. At the same time, cyclic interpulmonary changes during gas percussion make it possible to “wash out CO2” and improve oxygen absorption.

The device itself, together with the container (4), can be installed on any stable surface during therapy, in between, or immediately after use, without compromising their functional properties for their intended purpose. The body with the container (4) can be assembly units that are connected to each other during its manufacture into one common structure using assembly operations.

The presented figure, description of the design and use of the device for intrapulmonary percussion ventilation do not exhaust the possible design options and do not in any way limit the scope of the proposed technical solution. Other options for execution and use are possible within the scope of the claimed formula.
