SU1286202A1 - Apparatus for auxiliary artificial ventilation of the lungs - Google Patents

Abstract

The invention is intended for assisted artificial ventilation of the lungs in children with a III-IV degree stenosing laryngotracheitis. The device contains a fitting 1, an ejector 2 outputs with a nozzle 20 and a chamber 21, a switch 3, microtracheostomy 4 for connection to a patient with a fixing circle 5. Switch 3 consists of an inlet jet valve 11 with channels 12, 13 and 14, a petal check valve 15 and the outlet jet valve 16 with channels 17, 18 and 19. A microtracheostomy 4 is injected into the patient's trachea. When you inhale, the valve 15 opens and the gas flows through the channels 12, 13, 17 and 19 to the patient, while simultaneously sucking air through the chamber 21 and channel 18. When exhaling, valve 15 is closed, g The gas switches to the channel 14 and through the tube 7 through the nozzle 20 and the chamber 21 is released into the atmosphere. 1 hp f-ly, 1 ill.

The invention relates to medicine and can be used for assisted ventilation of the lungs in case of stenosing laryngotracheitis, grade III-1U, in children.

The purpose of the invention is to increase the reliability of the design.

The drawing shows schematically a device for assisted mechanical ventilation of the lungs.

The auxiliary device artificially sucks in the ambient air of the ventilatory ventilation of the lungs and contains a choke pipe of the mixing chamber 21 and the channel 18.

1 gas supply, ejector 2 expiration, ne-When the patient exhales, the valve 15 closes the switching unit 3, the patient attachment element in the form of a microtracheostomy 4

with fixing circle 5 with holes 6

and the gas is switched to the channel 14. Through the tube 7, the gas enters the working nozzle 20 of the ejector 2 exhalation and through the chamber 21

for the luminaire and connecting tubes 7-10. mixing into the atmosphere, facilitating the exhalation of pa-switching node 3 is included directly. Due to the resistance microstep between the power fitting 1 and the tracheostomy 4. It consists of

Tracheostomy 4, at the end of expiration, an elevated pressure is created, indicated in stenotic laryngotracheitis.

with one switchable input channel 12 for power and two output channels 13 and 14, an intermediate rubber flap check valve 15 and an outlet jet valve 16 with an input channel 17, an output channel 18 and a common switchable channel 19 for the patient's accessory element.

The ejector 2 exhalation is placed on the output jet valve 16 of the switching unit 3 and has a working nozzle 20 connected by a tube 7 with the output channel 14 of the input jet valve 11 of the switching unit 3, and the mixing chamber 21 communicated with the atmosphere.

Microtracheostomy 4 is a thermoplastic tube with a length of about 45 mm and a diameter of about 2.5 mm, bent at 90 ° along a bend radius of 15 to 20 minutes.

Claims (2)

1. A device for assisted artificial ventilation of the lungs, comprising a gas supply nipple, an exhalation ejector, a switching node, a patient attachment element and connecting pipes, characterized in that, in order to increase the reliability of the design, the switching node is connected between to the patient and consists of serially connected inlet jet, petal check and output jet valves, and an exhalation ejector is placed on the output jet valve and communicated between stvom connection tube to the inlet jet valve switching node. 2. A device according to claim 1, characterized in that the patient attachment element is designed as a microtracheostomy. shimm way. Microtracheostomy 4 is injected into the patient's trachea and around 5 is fixed on the neck. The fitting 1 is connected to the respiratory gas source, and the channel 19 is connected to the microtracheostomy 4 by means of the connecting tube 10. When the patient inhales, the valve 15 opens and the gas enters microtracheostomy 4 and the patient through channels 12, 13, 17 and 19. The gas leaving channel 17 simultaneously draws in ambient air through mixing chamber 21 and channel 18. cient. Due to the resistance of microtracheostomy 4, by the end of expiration, an increased pressure is indicated, shown in stenotic laryngotracheitis. Invention Formula 1. A device for assisted artificial ventilation of the lungs, comprising a gas supply nipple, an exhalation ejector, a switching node, a patient attachment element and connecting pipes, characterized in that, in order to increase the reliability of the design, the switching node is connected between to the patient and consists of serially connected inlet jet, petal check and output jet valves, and an exhalation ejector is placed on the output jet valve and communicated between stvom connection tube to the inlet jet valve switching node. 2. A device according to claim 1, characterized in that the patient attachment element is designed as a microtracheostomy.
