Definitions
- the present invention relates to a respirator normally used for artificial respiration in people who cannot breathe on their own.
- respirators are widespread in hospitals, in ICU departments where there are critically ill patients, and also emergency ambulances carry patients with respiratory problems.
- respirators are mostly made up of shells that house a manual resuscitator or an AMBU-type self-inflating bag (Airway Mask Bag Unit).
- Ventilators are also used within hospitals for temporary ventilation of ventilator-dependent patients when the ventilator needs to be examined for possible malfunctions, or when ventilator-dependent patients are transported within the hospital.
- respirators may be manual if used for a short period of time. time, during which a person presses the bag at certain intervals to provide air to the user, or automated, if they are used for long periods of time.
- Automated resuscitation devices comprise a drive device that moves at predetermined intervals into an open position and a closed position. In the closed position, the mechanism presses the bag to provide air to the user, and in the open position it allows air to enter the interior of the bag to provide it in the next cycle to the user.
- an object of the present invention is to provide a respirator of reduced dimensions, number of parts, weight and cost, as well as reusable after autoclaving the self-inflating bag as a standard element.
- the objective of the invention is to achieve a portable and hands-free autonomous respirator for emergency medical services and that the energy source is compressed air.
- respirator according to the present invention is defined by the independent claim. Additional features are defined in the dependent claims.
- the power source can be portable, such as the oxygen bottle carried by the health worker in the ambulance, in the emergency backpack, or at a fixed point such as the medical air intake of the hospital. hospital bed head.
- the volume of air that can be delivered to the patient is approximately 30% greater than the volume delivered with two-handed manual pumping.
- a palatal model diving regulator type mouthpiece is used, which must be held between the patient's teeth.
- This mouthpiece is coupled by means of an adapter to a tube with a specific curvature and with variable sections, such that they allow the air to be taken directly to the oropharynx and, in turn, hold the tongue against the palate, preventing it from falling due to relaxation. , plugging the airway.
- the patient upon regaining semiconsciousness and the gag reflex, will have convulsions when noticing a foreign body, and these signs will serve as a warning that he has returned to semiconsciousness.
- a cannula that is less invasive than the Guedel cannula and easier to insert into the patient's throat, it provides the option that it can be used by personnel with less health qualifications, allowing greater scope in the personnel that can use it.
- This respirator due to the way it has to be used in emergencies, uses a mask with an inflatable cushion and a harness to hold it on the patient's head.

- Figure 6C is a sectional view of sections A-A, B-B and C-C indicated in Figure 6; Y
- Figure 7 is a sectional view showing the detail of the internal protuberances of the sealed pressure chamber.
- the respirator according to the present invention comprises a sealed pressure chamber 1 and a control box 10.
- An AMBU-type tubular membrane 2 is placed inside the sealed pressure chamber 1, with two non-return valves 4, a front non-return valve and a rear non-return valve, positioned in such a way that the air can only circulate in one direction. .
- the anterior non-return valve 4 comprises a relief or overpressure valve 8, which prevents the patient from receiving an overpressure that could damage the lungs.
- the pressure chamber 1 In the internal part of the pressure chamber 1 fluid inlets and outlets 7 are placed, for example, it also has protrusions 9, which, for example, are different from each other.
- the low-pressure compressed medical air that is introduced into the chamber 1 exerts pressure on the tubular membrane 2, and forces the membrane 2 to deform in a predetermined shape.
- this default shape is a tricuspid shape, although any suitable shape could be provided.
- these protuberances 9 physically press the tubular membrane 2 by dimensional interference, giving it a predetermined shape. That is, the pressure on the tubular membrane can be exerted by the fluid coming from the outlets and/or by the protuberances 9.
- a flat transverse membrane 5 made of elastic material is placed which, through a flange 6, or a flange quick opening 3.1, and some screws, is pressed against the sealed chamber 1, fixing the membrane 2 to the pressure chamber 1 in a sealed manner.
- the pressure chamber 1 is sealed on this side and, in turn, absorbs the differences in elongation of the tubular membrane 2 that occur when it collapses and expands. It also allows absorbing the overpressure that could be inside the pressure chamber 1, acting as a diaphragm.
- This flange 6 acts as a support or legs for the respirator body.
- a quick-opening flange 3.1 presses two half-shells of chamber 1 in its central part and seals chamber 1 through an O-ring 1.1.
- the tubular membrane 2 is subjected to a controlled pressure and for a period of time and with a controlled flow rate, through a control panel 10 and a number of cycles per minute.
- the way in which the tubular membrane 2 collapses is related to the period of time during which we subject it to pressure, the pressure to which it is subjected, and the air flow that we inject between the tubular membrane 2, the pressure chamber 1 and to the shape of the protuberances 9 located in the pressure chamber 1. From this control of the flow rate, the pressure and the time, the collapse of the membrane 2 in one third, in two thirds or in its entirety is derived.
- the supply of air to the patient is directly related to the deformation of the tubular membrane 2 controlled through the control box 10.
- FIGS 3 and 4 show the control panel 10 of the respirator according to the present invention and its indicators, while Figure 5 shows the sockets of said control panel 10.
- This control panel 10 comprises a solenoid valve 11, which regulates the incoming pressurized air, for example, to a maximum of 2 bars.
- This solenoid valve 11 is controlled by a PLC (programmable logic controller) 12, which allows to regulate the passage, time and, consequently, the volume of air that is supplied to the sealed pressure chamber 1.
- PLC programmable logic controller
- the control panel 10 also includes a fine-adjustment unidirectional regulator 29 and two quick exhaust valves 7, that when the solenoid valve 11 is changed through the PLC 12, there is no pressure in the quick exhaust valves 7, which open and automatically let the air escape from the pressure chamber 1 to the atmosphere, allowing the membrane 2 to recover its primitive shape, and leaving it ready for the next cycle.
- the elements that make up the control panel 10, together with the rest of the respirator elements, provide versatility to carry out multiple combinations of number of cycles, duration of these cycles, intervals between cycles, etc., which will be programmed based on the needs.
- a pressure sensor 13 is located in the solenoid valve 11 that checks at all times that we have pressure when we inject air into the membrane 2, that it will be compressed correctly, that it is not broken, and in general that we have the right pressure to start the maneuvers. Cycle.
- the operation of the respirator according to the present invention is as follows.
- an air inlet 19 is connected, for example, 2 bars, which in the embodiment shown is located in the lower left rear part of the control panel 10.
- An air outlet 16 is also connected, which in the embodiment shown is located on the upper left rear of the control box 10, and a cable in socket 15, located according to the embodiment shown, in the rear right central part of the control panel 10, and to a socket.
- a general switch 18 and a start button 23 must be activated, and a light 24 will come on, for example, green, to inform the user.
- the respirator will start up, cyclically compressing and decompressing the tubular membrane 2 through the fluid outlets and/or through the protrusions 9. According to one example, by default it starts at 15 minute cycles.
- the ventilator continues to function until a stop button 25 is actuated, or a fault is detected. In the event that a fault is detected, an audible alarm 17 would sound and an alarm light 28 would come on.
- a switch 20 is pressed, turning on a light 22, and to select 18 cycles per minute, a switch 21 is pressed, turning on a light 26.
- a light 24 for example blue, lights up on the control panel 10 for each cycle the ventilator performs.
- the stop button 25 After an alarm, to reset and start again, the stop button 25 must be pressed, then the start button 23 must be pressed. If no anomalies are detected, the ventilator will start the air cycles again.
- control panel 10 comprises the following elements on its front part:
- Start button for example, black
- Stop button for example, red
- Driving indicator light for example, green
- Respirator cycling indicator light for example, blue
- 20 12-cycle request switch to ventilator, for example, colored yellow
