Abstract

An artificial lung ventilation apparatus containing a respiratory circuit, respiratory furs of a larger and smaller volume with a drive and a control unit, characterized in that the apparatus is equipped with two pneumatic taps, a smaller respiratory fur is placed in a cavity of a larger fur cavity, each of which pneumatic taps is installed at the output of its furs, and their outputs are combined into a common collector connected to the respiratory circuit.

Description

AIHIAJ AT LUNG ARTIFICIAL VENTILATION

The utility model relates to the field of medical equipment, namely, devices for artificial lung ventilation.

Known is a ventilator ll containing dxeKTfp inhalation with high-pressure and low-pressure lines at the outlet and a respiratory control valve; nof ©, who, with the aim of performing artificial ventilation of the lungs in patients of different ages, including children, is equipped with a pneumatic amplifier with a variable throttle.

The closest technical solution adopted for the prototype is an artificial lung ventilation apparatus 2, containing a respiratory circuit, respiratory bellows of a larger and smaller volume with a drive, and a control unit.

The proposed device differs from the analogue in the principle of organizing respiratory flow control, although it solves a similar problem, and from the prototype in constructive execution of a pressure generator based on respiratory bellows, which provides simple, reliable and easy-to-use switching of the volume of the respiratory mixture, which allows serving patients of various ages.

The indicated effect is achieved due to the fact that the apparatus is equipped with two pneumatic taps, a smaller respiratory fur is located in the cavity of a larger volume fur, with each of the pneumatic taps installed at the outlet of its fur, and their outputs combined into a common manifold connected to the respiratory circuit.

The proposed apparatus is shown in the functional diagram. It consists of a breathing circuit I, a large-volume fur 2 with a pneumatic crane 3, a smaller-volume fur 4, located in the cavity of the fur 2, with a pneumatic crane 5. The outputs of the pneumocranes are combined into a common manifold 6 The bellows are driven by a drive 7, controlled by the control unit 8 A typical electromechanical drive can be used as a drive, and standard cranes with manual control can be used as pneumatic valves.

The device operates as follows.

The volume of the respiratory mixture with a constant course of bellows has three values determined by the position of the pivot screens: each one is open separately or both together. The bellows work simultaneously under the action of a common drive pusher 7, controlled by a control unit 8 according to a given program

/)

The proposed apparatus provides:

-changing the volume of the respiratory mixture in a wider range compared to the prototype;

-convenience® and reliability in operation, since the change in volumes is carried out by switching pneumatic cranes, which eliminates the need for mechanical work to rearrange the bellows in the prototype,
