    Assisted breathing equipment. The equipment works by means of two valves that allow to inflate a flow of air/oxygen at a stable and concrete pressure, and at the same time maintain an equally constant PEEP pressure. It consists of two independent branches that are connected in parallel through connectors (22-22') to the corresponding mask (8), so that through a series of elements they allow to control the pressure and volume of both the inhaled air and exhaled, having means to regulate the number of cycles per minute, and generate alarms in the event of any anomaly.

    [0002] Assisted breathing equipment
    [0004] TECHNICAL SECTOR
    [0006] The present invention refers to a breathing aid equipment specially designed to assist people with severe respiratory difficulties.
    [0008] The object of the invention is to provide an efficient, simple and inexpensive respiratory aid equipment.
    [0010] BACKGROUND OF THE INVENTION
    [0012] In the field of practical application of the invention, the respiratory assistance equipment on the market is materialized in structurally very complex and consequently very expensive equipment, to the point that its purchase involves such a high investment that this type An extremely small number of teams participate in hospitals, clearly insufficient in times of pandemics.
    [0014] EXPLANATION OF THE INVENTION
    [0016] The assisted breathing aid equipment that is recommended solves in a fully satisfactory way the problems mentioned above, based on a simple but effective solution.
    [0018] For this, the device of the invention is constituted from a device in which two independent operating branches are defined, which are connected in parallel to the medical tube of the corresponding mask to assist breathing.
    [0020] More specifically, a first branch is defined, intended to control inspiration, and a second branch, to control expiration.
    [0021] The pressure in the inspiratory limb is regulated by a pressure regulator that works in a range between 0 and 100 grams and a main flow regulator that works in a range between 0 and 10 kg, while the expiration pressure or pressure positive at the end of expiration (PEEP), it is regulated by a PEEP valve or mechanically by water column regulation.
    [0023] The device has a digital flow meter in the inspiration branch that allows to know the volume of air injected in each cycle.
    [0025] To do this, it has two motorized valves controlled by a PLC, associated with each branch, so that the inspiratory branch valve is in charge of controlling the flow of air and oxygen mixture that reaches the patient's lungs, while the Exhaust branch valve allows air to be expelled.
    [0027] The inspiration branch has a mechanical safety valve prior to a three-way valve through which the inlet air and oxygen mixture is regulated, including both branches of two digital pressure switches through which to control the pressure of the inspiration and expiration pressure of the patient, counting the inspiration branch additionally with a manometer.
    [0029] The system is controlled through a PLC, which has a series of buttons through which to select between different respiratory cycles (from 10 to 24) cycles per minute, including a screen and some controls to adjust inhalation times and exhalation as well as plateau times.
    [0031] Based on this structuring, the device allows to introduce an air / oxygen flow at a stable and specific pressure, between 0-60cm H2O, and in turn maintain a PEEP pressure between 0-60cm H2O.
    [0033] The equipment can work in two modes. Pressure control and volume control. In the first one, you can regulate the maximum pressure of inhaled air and the maximum pressure on exhalation. In the second of the modes, both the pressure in the two branches and the volume of air / oxygen introduced can be controlled.
    [0034] The control electronics will allow the generation of alarms due to excess pressure or lack of it, as well as volume alarms if the established flow is not reached, an alarm of involuntary disconnection of tubes as well as obstruction.
    [0036] As it has automatic control, the system is valid for invasive and non-invasive operation and also has an Ethernet connection so it can be monitored in a common station, together with other devices.
    [0038] DESCRIPTION OF THE DRAWINGS
    [0040] To complement the description that is going to be made below and in order to help a better understanding of the characteristics of the invention, according to a preferred example of a practical embodiment thereof, a set of drawings is attached as an integral part of said description. where, for illustrative and non-limiting purposes, the following has been represented:
    [0042] Figure 1.- Shows a schematic view of the fundamental elements that participate in an assisted breathing aid equipment made in accordance with the object of the present invention.
    [0044] Figure 2.- Shows a view similar to that of figure 1, but corresponding to a second variant embodiment in which the PEEP valve has been replaced by a mechanical water column regulation mechanism.
    [0046] Figure 3.- Shows an electrical diagram of the device.
    [0048] Figure 4.- Shows, finally, a front perspective view of the equipment of the invention.
    [0050] PREFERRED EMBODIMENT OF THE INVENTION
    [0052] In view of the outlined figures, it can be seen how the assistive breathing equipment of the invention is constituted from a casing (29), in which it is integrated a PLC circuit (12), with its corresponding voltage adaptation electronics (13) and connection (14) to the network, a PLC circuit (12) that controls a pair of solenoid valves (4-9), as well as another series of devices that they will be described below.
    [0054] The equipment consists of two independent branches, an inspiration branch (1) and an exhalation branch (2), which are connected in parallel through the corresponding connectors (22-22 ') to the corresponding mask (8), of assistance to breathing.
    [0056] The first branch (1) has a three-way valve (16) through which the air (18) and oxygen (17) inlet mixture is regulated, and this mixture can be regulated between 21 and 100% of oxygen.
    [0058] Said first branch (1) includes a cut-off valve (2), after which a pressure regulator (3) is established, which works between 0 and 100 grams of pressure, which communicates with a lung reservoir (19) with a volume of the order of 1.5 liters, after which the aforementioned solenoid valve (4) is established, then a digital flow meter (20) and a main flow regulator (5) are established that works in a range between 0 and 10 kg. In series with said regulator, an exhaust valve (7) and a pressure gauge (21) are established to control that the maximum allowed pressure is not exceeded at any time, then and also in series a pressure switch (6) is established to monitor the pressure. inspiration pressure through a display (30).
    [0060] For its part, the exhalation branch (11) will also have a pressure switch (6 ') that allows monitoring the inspiration pressure through a display (31), being assisted by the second solenoid valve (9), as well as by a PEEP valve (10).
    [0062] As can be seen in figure 2, the PEEP valve (10) can be optionally replaced by a mechanical regulation system by water column (23), in which the outlet end of the exhalation conduit (11) It will be able to move vertically over a water tank with its corresponding scale (26), level (24) and emptying drain (25).
    [0064] In figure 4 it can be seen how the device has a series of buttons (28) through which to select between different respiratory cycles (from 10 to 24) cycles per minute, including a screen (26) and controls (27) for adjusting the inhalation and exhalation times, as well as the plateau times.
    [0066] Based on this structuring, the device allows the introduction of an air / oxygen flow at a stable and specific pressure, between 0-60cm H 2 O, and in turn maintain a PEEP pressure of between 0-60cm H 2 O.
    [0068] As previously mentioned, the equipment can work in two modes. Pressure control and volume control. In the first one, you can regulate the maximum pressure of inhaled air and the maximum pressure on exhalation. In the second of the modes, both the pressure in the two branches and the volume of air that is introduced can be controlled.
    [0070] As for the diameter of the ducts, it may vary according to different embodiments, although by way of example, the aspiration duct would have a diameter of the order of 8 millimeters, while the exhalation duct would have a diameter of the order of 16 millimeters.
    [0072] Finally, it only remains to point out that, as has been said previously, the control electronics include means for triggering alarms due to excess or lack of pressure, lack of flow, involuntary disconnection of tubes, as well as obstruction.
