CS233230B1 - Multifunctional valve for artificial ventilation - Google Patents

Abstract

The invention relates to a multi-functional valve for artificial ventilation of the lungs, with the help of which filling of the patient with a mixture of gases or air with a manual breathing bag or a breathing machine is solved. The essence of the multi-functional valve for artificial ventilation pTúc is also the design of the valve body, breathing membranes and control springs, which allow filling the patient with a gas mixture or air using a manual breathing bag, a breathing machine, separate inhalation of the patient, his separate exhalation into the atmosphere without excess pressure, further using a control spring to smoothly adjust the excess pressure at the end of the patient's exhalation. A spring-loaded safety valve is located in the same valve body, which can be used to preselect the protective value of the safety pressure according to the type of patient - adults, children and infants. This valve protects the patient's respiratory tract and lungs from an increase in pressure that can occur due to careless operation or a malfunction of devices that do not supply the patient with a mixture of gases or air through the multi-functional valve for artificial ventilation.

Description

233230 2

BACKGROUND OF THE INVENTION The present invention relates to a multi-function valve for artificial ventilation, by means of which the patient is filled with a mixture of gases or air through an ore breathing bag or a breathing machine.

So far known pTúc ventilating valves allow only inspiration and exhalation, relief valve and overpressure relief at the end of exhalation are performed by separate devices that connect to the valve by means of conical couplings or screw connections. The disadvantage of these combined devices is the great complexity, size, weight and difficulty of distenlation, disinfection and sterilization.

The aforementioned drawbacks are eliminated by a functional valve for the artificial valve, which is also the embodiment of the valve body, the breathing membranes and the control springs, that allow the patient to fill the mixture with gases or air through an ore vent bag, a respirator, a separate patient breath, a separate patient exhalation into the atmosphere without overpressure; A spring-loaded safety valve is located in the same valve body to preset the pressure relief value according to the patient type - adults, children and infants.This valve protects the respiratory tract and floats the patient from pressure build-up! by careless operation or equipment failure, which, through a multi-function valve for artificial lung ventilation, imparts a mixture of gases or air to the patient.

By placing the functional parts of the valve in one body, it is possible to simplify the operation of the device, reduce the weight, dimensions and number of cracks, reduce the number of connecting parts and hence the number of possible leaks, reduce the dead space of the system, simplify distenla, disinfect and sterilize. The multi-function valve allows the patient to stand alone, his or her own exhalation, the overpressure at the end of the exhalation and the adjusted exhalation overpressure.

1 is a sectional view of the valve and FIG. 2 is a side view of the valve.

The multi-function valve for artificial ventilation pTúc is formed from an inlet body 1 with a neck 2, to which an outlet body 4 provided with an outer cone g, an inner cone 6 and exhalation openings 1 is attached by means of nuts 2. A flat membrane gs is inserted between the inlet body 7 and the outlet body A through the openings of the membrane 2i on which the shaped membrane 10 is fixed.

The flat membrane g of the seat rests on the membrane seat 11. or is tightened by a ring 12, which is viewed by a spring 13 adjustable by means of a knob 14, which is to be connected to a plunger 15. The positioning and tightness of the system is provided by a sealing ring 16. In the outlet body 4, a safety valve body 17 is provided with openings formed by the seat 18 of the sealing plug. 12, the springs 20 and the thumb 21. The thumb 21 is slidably mounted in the opening 22 of the adjusting ring 23.

The input body 1 shown in FIG. 2 is provided with an annular scale 42, a control knob 14 with a pointer 42, a rotatable adjusting ring 23 and an actuating thumb 44 of the relief valve 17 in an extended position.

With the patient's individual breath coming through the inner cone 6 of the output body 4, the flat membrane g is pressed against the diaphragm seat 11 and the shaped membrane 10 is deflected. The gas or air mixture enters through the inlet body 1 and the membrane openings 2 in the flat membrane g and through the inner cone g into the patient.

Claims (2)

3 233230 When inhaled by a hand breathing bag or breathing apparatus connected to the inlet body 1, the flat membrane g is pressed against the sediment diaphragm J by the pressure of a mixture of gases or air, the shaped diaphragm Jg is pivoted and a gas or air mixture flows through the diaphragm holes g inner cone ga patient. When the patient exhales into the inner cone g, the shaped membrane 10 is pressed against the flat membrane g and closes the openings of the membrane g. The flat membrane g is lifted from the seat of the membrane 11 and the mixture of gases or air passes through the exhalation holes g in the outlet body 1 to the atmosphere. If the flat diaphragm g is pressed against the diaphragm seat 11 by the control spring 13a with a ring gg, no residual pressure remains in the patient. By adjusting the pressure of the actuating spring 11 by means of the actuating knob 11, the pusher 12 presses the flat diaphragm g on the seat of the diaphragm 11 and the patient exhales only a part of the gas or air mixture and remains in the flowing line a residual pressure corresponding to the setting of the pointer 25 on the button controller H against the value on the scale 24 This residual pressure at the end improves oxygen transfer to the patient's bloodstream. The thrust pressure is adjusted by means of an actuating thumb 21 which is inserted into the telescoping valve 17 and the actuating thumb 21 is rotated in this position by turning the adjusting ring 2j. thereby tightening the spring pressure 20 through the sealing plug 19 to the seat 1g. When adjusting ring gg for adjusting ring 23, the control finger 21 itself extends, thereby reducing the spring pressure 20 through the sealing plug 19 to the seat 1g. In the event of a malfunction or failure of the breathing devices connected to the inlet body 1 of the multifunctional valve for the pTúc valve, thereby filling the patient with a pressure of gas or air mixture as permitted and adjusted, the sealing plug 19 is retracted from the seat 18 and the excess The gas pressure can be blown into the atmosphere through the exhalation openings g. The invention can be used for all kinds of hand-held breathing apparatus and breathing apparatus mainly in rescue practice where small size, weight and ease of use are required. The invention can also be used for a simple anesthesia device, even if not inhaled, also used in rescue practice. P R E D Η E T Ϊ K k L E Z U 1.
