Description

TECHNICAL FIELD

The invention belongs to the field of medical devices, and specifically, it is a distributor of an artificial lung ventilation device.

STATE OF THE ART in the normal application of artificial lung ventilation, the ventilation parameters are selected according to a specific patient, but when it is decided to divide the artificial lung ventilation apparatus for several patients, the problem of individualization of the parameters arises. When the contours of inhalation and exhalation are elementary divided, the principle of communicating vessels comes into effect and this leads to two fundamental problems:

(a) Problem of varying lung continuity. according to the data of various authors, the inhaled volume in lungs of different continuity differs significantly - in a lung with low continuity (0.02 cmHzO/l) 510 ml, in a lung with normal continuity (0.04 cmHaO/l) - 980 ml;

b) Contour contamination, infection problem. In the case of a certain patient's spontaneous breathing or coughing efforts, there is a possibility for the spread of infectious pathogens and it automatically interferes with the ventilation of other patients.

Ventilators can be volume and pressure controlled. When the ventilator is shared between several patients, volume-controlled ventilation modes lose their meaning. Not only do they not guarantee that a certain patient will be ventilated at the selected volume, but the patient with the lowest lung resistance will experience lung overstretching and pressure trauma, causing the problem of infection.

Due to the high initial inspiratory flow and the constant pressure in the circuit, artificial lung ventilation in pressure-controlled modes leads to several undoubted advantages - the probability of pressure injury is significantly reduced, the inhalation of patients with different lung continuity starts at a similar time, if the resistance in one of the circuits (obstruction of the intubation tube) increases significantly, the remaining patients are not injured. i.e. ventilation volumes do not increase in unobstructed contours, ventilation volumes are adapted according to patients' anthropological data ~ average inspiratory pressure in the population of healthy patients is a more constant parameter than respiratory volume.

Adaptive ventilation modes (modes that allow the patient to breathe next to the applied artificial lung ventilation) are incompatible with the ventilation of several patients with a single artificial lung ventilation machine.

Most attempts have been made by elementary dividing the inspiratory and expiratory contours into several separate contours, but it remains unclear whether it is possible to ensure an adequate ventilation volume in patients with different lung continuity. The majority of authors propose to solve the problem of different lung continuity by increasing the resistance in the branch of the lower resistance of the lung, using a Hotfman clamp. Clamping the contour of the normal lung continuity and reducing the peak inspiratory pressure to 17.8 cmHzO increases the peak inspiratory pressure in the low continuity lung to 33.2 cmHzO, and achieves adequate ventilation of the different lungs (0.02 cmHžO/l and 0.04 cmhkO/l) (495 ml and 499 ml). However, the use of the Hoffman clamp in a dynamic real environment is impractical, unstable, does not provide security, and is therefore inappropriate.

Other authors propose to solve this problem by means of a solenoid electronic air flow valve. These valves are grouped into two groups: two-position valves and variable-flow high-definition valves. Using a two-position valve gives a close result to a portable ventilator. However, the disadvantage is that only two valve positions (on/off) are possible, so such valves are not suitable for lungs of different lengths. The use of variable permeability high-definition valves uses computerized algorithms to control the airflow throughout inspiration (8i-tevel result), bringing the system closer to a stationary ventilator. In this case, although the problem of the continuity of different lungs is solved, other shortcomings of the method remain: the breathing gas mixture is mixed between different patient circuits, the possibility of infection between different patients remains, if one of the circuits is accidentally disconnected, the artificial lung ventilation in the remaining circuits immediately changes.

Patent document US2020398015A1 (published 2020-12-24) describes a distributor for artificial lung ventilation - an accessory that can be adapted to an existing mechanical ventilator. However, such a divider can only be applied to two patients, and in addition, such two patients must be of similar lung continuity. If the continuity of the lungs is different, or even more so unknown, such a pulmonary ventilation divider cannot be adapted for different patients.

The found analogues of the technical equation, compared to the solution presented in this description, have shortcomings, the technical solution presented in this description does not have the mentioned shortcomings, and solves the mentioned problems.

Fig. depicts a distributor of an artificial lung ventilation apparatus (1), which has a regulator of the flow of the breathing gas mixture (2), a supply line of the gas mixture (3), an artificial lung ventilation circuit (4), a regulating cylinder (5), a two-way valve (11) and an emergency overpressure valve (9).

BEST IMPLEMENTATION OPTIONS

A manifold for a multi-patient artificial lung ventilation apparatus (1) is described, which allows pressure-controlled artificial lung ventilation. The distributor of the artificial lung ventilation device (1) is connected to the artificial lung ventilation device (1) and divides the artificial lung ventilation device (1) into more than one artificial lung ventilation circuit (4), so during anesthesia or intensive therapy with one artificial lung ventilation device (1) more than one patient can be ventilated. Typically, the ventilator (1) has a gas mixture flow regulator (2), one gas mixture supply line (3) and one ventilator circuit (4). The gas mixture supply line (3) supplies a gas mixture of the required concentration to the artificial lung ventilation circuit (4) for lung ventilation of patients, and the gas mixture exhaled by patients is removed to the environment.

In the case of the present invention, the distributor of the ventilator (1) has the following additional components:

more than one artificial lung ventilation circuit (4);

adjustment cylinder (5);

inhalation valve (6);

exhalation valve (7);

PEEPV valve (8);

emergency overpressure valve (9).

Fig. depicts a ventilator (1) distributor having four gas mixture supply lines (3) and four ventilator circuits (4). In the described case, there are four artificial lung ventilation circuits (4), but there may be one, two, three, four or more of them. Since in the case described, the distributor of the artificial lung ventilation apparatus (1) has four artificial lung ventilation circuits (4), the supply lines (3) of the gas mixture are also four. Gas mixture supply lines (3) are a system of medical tubing that delivers oxygen to the artificial lung ventilation circuit (4). Gas mixture supply lines (3) are connected to the patient's breathing tubes, such as endotracheal tubes. Most of the time, the gas mixture supply line (3) supplies gas with 100% oxygen concentration, but in individual cases, the oxygen concentration may be lower. After using the venturi mechanism (10), the ambient gas mixture (air) enters the gas mixture supply line (3), and thus the oxygen concentration in the gas mixture supply line (3) decreases. The artificial lung ventilation circuit (4) is a high-pressure circuit for non-invasively delivering a respirable gas mixture to the patient's lungs and removing the patient's exhaled gas mixture from the lungs to the environment.

In the circuit (4) of the ventilator, there is an adjustment cylinder (5), which consists of:

diaphragm (5.1), piston (5.2) and piston regulator (5.3). In the described case, there are four regulating cylinders (5), one regulating cylinder (5) for each circuit (4) of the ventilator. The membrane (5.1) is used to separate the mixture of gases breathed by patients in a separate artificial lung ventilation circuit (4) from different patient artificial lung ventilation circuits (4). This eliminates the possibility of cross-contamination, protects against infections, viruses or bacteria, ideally, the regulating cylinder (5) is made of a transparent material, so it is possible to observe the membrane (5.1) and visually estimate the volume of the gas mixture breathed by individual patients. The piston (5.2) and the piston regulator (5.3) installed in the regulation cylinder (5) provide an opportunity to individualize the inspired volume of the breathing gas mixture for each patient.

The gas mixture exhaled by the patients is removed to the environment through the exhalation valve (7) and the PEEPV valve (S), which are located in the circuit of the artificial lung ventilation apparatus (4). The exhalation valve (7) is one-way, so the patient's exhaled gas mixture cannot flow back into the regulating cylinder (5), thus avoiding re-inhalation of already exhaled gas. The exhalation valve (7) is open in the neutral position, so the gas mixture exhaled by the patients is easily removed through it. during inhalation, the exhalation valve (7) is closed due to the positive pressure created by the artificial lung ventilation apparatus in the pre-membrane part. The exhalation valve (7) is connected to the regulating cylinder (5), which is filled with the breathing gas mixture during exhalation. The gas mixture exhaled by the patients passes through the exhalation valve (7) to the PEEPV valve (8). One end of the PEEPV valve (8) is in contact with the circuit of the artificial lung ventilation device (4), and the other end is in contact with the environment. The PEEPV valve (8) is also one-way, and it removes the patient's exhaled gas mixture from the ventilator circuit (4) to the environment. At the end of expiration, an individual positive pressure is achieved, usually 0-20 cmHzO, which first opens the PEEPV valve (8) and then activates the inspiratory valve (6). the inspiratory valve (6) is located in the artificial lung ventilation circuit (4) between the patient and the regulating cylinder (5). The positive pressure created at the end of exhalation activates the inspiratory valve (6), which opens, and when the inspiratory valve (6) opens, the respirable gas mixture enters the patient's lungs from the regulating cylinder (5). When the inspiratory valve (6) opens, it closes the expiratory valve (7), so that during inhalation the expiratory valve (7) remains closed and prevents the inhaled gas mixture from escaping into the environment.

The distributor of the ventilator (1) has an emergency overpressure valve (9) (Figure 1). The emergency overpressure valve (9) is located between the regulating cylinder (5) and the intake valve (6). It is a one-way valve that can pass the breathing gas mixture from the artificial lung ventilation circuit (4) to the environment. In the normal ventilation mode, the emergency overpressure valve (9) is closed, and in the event of an unexpected, emergency pressure increase in the artificial lung ventilation circuit (4) - it is automatically activated and releases the excess pressure to the environment. The emergency overpressure valve (9) prevents an unexpected increase in pressure in the circuit, thus protecting the patient's lungs from pressure trauma.

The distributor of the ventilator (1) may have a venturi mechanism (10) (Figure 1). The venturi mechanism (10) is located in the gas mixture supply line (3). This is the mechanism that transfers the gas mixture in the environment, in the room, to the gas mixture supply line (3). With the help of the venturi mechanism (10), it is possible to change the concentration of oxygen in the breathing gas mixture, but the air is taken from an environment that is not necessarily sterile.

Additionally, the distributor of the ventilator (1) has a control device (12).

The control device (12) is a computer, tablet, mobile phone or other computer tool that allows controlling, monitoring or recording the operation of the player of the artificial lung ventilation device (1) and related parameters. The control device (12) has entered standard values of monitored signals and standard values of alarm signals. With the help of the control device (12), it is also possible to set the desired signal parameters and threshold values, when alarm signals are generated, and what type. The signals of the player of the artificial lung ventilation device (1) can be presented on the screen of the control device (12), sound messages can be generated, the signals can be sent to a remote mobile device, computer cloud system or other computer tools.

In one embodiment of the described invention, the inhalation valve (6), the exhalation valve (7) and the PEEPV valve (8) are combined into one bidirectional valve (11). In this case, the distributor of the ventilator (1) has the following essential components, which are shown in Figure 2:

more than one artificial lung ventilation circuit (4);

adjustment cylinder (5);

two-way valve (11).

emergency overpressure valve (9).

The distributor of the ventilator (1) is similar to the one described above, only instead of three separate valves, there is one bidirectional valve (11). In the described case, the two-way valve (11) is located in the artificial lung ventilation circuit (4) between the patient and the regulating cylinder (5). The two-way valve (11) is a two-way gas flow valve widely used in self-inflating bags (Ambu-type bags) and portable artificial lung ventilation devices during anesthesia or intensive therapy. The two-way valve (11) regulates the residual positive pressure (0-20 cmHaO) at the end of exhalation, thus achieving an individual positive pressure at the end of exhalation for each patient. The bidirectional valve (11) controls exhalation depending on the pressure in the artificial lung ventilation circuit (4): when the pressure is positive, the expiratory part of the bidirectional valve (11) is closed, and the inspiratory part is opened. When the pressure drops, the inhalation part is closed and the exhalation part is opened. During exhalation, the gas mixture exhaled by the patients is removed from the artificial lung ventilation circuit (4) into the environment, and since the inhalation part is closed, the gas mixture exhaled by the patients does not enter back into the artificial lung ventilation circuit (4). during inhalation, the supplied gas mixture from the artificial lung ventilation circuit (4) enters the patient's lungs.

The artificial lung ventilation method is based on the above described artificial lung ventilation apparatus (1) (Figure 1, Figure 2) and has the following steps:

- entering the breathing gas mixture into the gas mixture supply line (3)

The artificial lung ventilation device (1) supplies the breathing gas mixture to the gas mixture supply line (3), the volume of the breathing gas mixture is regulated by the gas mixture flow regulator (2).

- removal of gas mixture exhaled by patients in the environment

In the case (Fig. 1), when the distributor of the ventilator (1) has an inhalation valve (6), an exhalation valve (7) and a PEEPV valve (8), the patient's exhaled gas mixture freely passes through the exhalation valve (7) and reaches PEEPV valve (8). At the end of exhalation, an individual positive pressure is achieved, which opens the PEEPV valve (8), and the patient's exhaled gas mixture is expelled from the ventilator circuit (4) into the environment.

When the distributor of the ventilator (1) has a two-way valve (11) (Fig. 2), the exhalation part of the two-way valve (11) is opened when the pressure in the ventilator circuit (4) drops. During exhalation, the gas mixture exhaled by patients is removed into the environment.

- filling the regulating cylinder (5) with a breathing gas mixture

The regulating cylinder (5) is filled with the breathing gas mixture during exhalation. In the case (Figure 1) when the distributor of the ventilator (1) has an inspiratory valve (6), an expiratory valve (7) and a PEEPV valve (8), the expiratory valve (7) is connected to the regulating cylinder (5), during exhalation, a positive pressure is created, which opens the regulating cylinder (5) and fills it with a mixture of breathing gases.

When the distributor of the ventilator (1) has a two-way valve (11) (Fig. 2), the two-way valve (11) activates the regulating cylinder (5) during exhalation, which is filled with the breathing gas mixture during exhalation.

In this way, during exhalation, the regulating cylinder (5) is filled with a mixture of breathing gases. Lungs of different length create different positive pressure, so a different volume of the breathing gas mixture enters the regulating cylinder (5), and thus the volume of the breathing gas mixture is individually selected for each patient. A different volume of the breathing gas mixture enters the regulating cylinder (5) for each patient automatically, according to the volume of the patient's exhaled gas mixture. Using the ventilator (1) distributor, it is possible to ventilate more than one patient with one ventilator (1). The gas mixture breathed by the patients does not mix with the general breathing gas mixture of the artificial lung ventilation machine and does not mix in this way between the different patient circuits. The breathing volume and individual positive pressure at the end of exhalation can be individually selected for each patient, thus the regulation cylinder (5) automatically solves the problem of different lung continuity.

- inhaling the breathing gas mixture from the regulating cylinder (5)

In the case (Figure 1) when the distributor of the ventilator (1) has an inspiratory valve (6), an expiratory valve (7) and a PEEPV valve (8), inhalation takes place with the help of the cyclic positive pressure generated by the ventilator (1) during exhalation. The positive pressure created at the end of exhalation activates the inspiratory valve (6). When the inspiratory valve (6) opens, the breathing gas mixture flows from the regulating cylinder (5) into the patient's lungs. the inspiratory valve (6) closes the expiratory valve (7), so during inhalation the expiratory valve (7) remains closed and prevents the respirable gas mixture from escaping into the environment.

When the distributor of the ventilator (1) has a bidirectional valve (11) (Fig. 2), the inspiratory part of the bidirectional valve (11) is opened by positive pressure in the ventilator circuit (4). Then, with the inspiratory part of the two-way valve (11) open, the patient inhales the respiratory gas mixture from the regulating cylinder (5).

By choosing a maximum lung-sparing ventilation pressure of 30 cmHžO, the highest possible initial inspiratory flow is achieved - thus reducing the latency in different patient ventilation circuits (4) and, as a result, reducing the probability of pressure injury in the maximal inspiratory ventilation circuit (4), which in this case does not exceed 30 cmH2O.

- removal of excess pressure from the artificial lung ventilation circuit (4) to the environment in the event of an emergency

In the event of an unexpected, emergency pressure increase above the expected rate in the artificial lung ventilation circuit (4), the emergency overpressure valve (9) is automatically activated, which removes the excess pressure from the artificial lung ventilation circuit (4) to the environment. The emergency overpressure valve (9) is one-way, so the gas mixture from the environment does not enter the artificial lung ventilation circuit (4), sterile conditions remain in the artificial lung ventilation circuit (4).

If the distributor of the artificial lung ventilation device (1) has a Venturi mechanism (10) (Fig. 1, Fig. 2), it is used to change the concentration of oxygen in the breathing gas mixture. In this case, the method has an extra step:

~ changing the oxygen concentration in the gas mixture supply line (3)

The venturi mechanism (10) allows changing the concentration of oxygen in the breathing gas mixture, because the venturi mechanism (10) transfers the gas mixture from the environment, rooms to the gas mixture supply line (3) and thus regulates the amount of oxygen in the breathing gas mixture.

The method also has this extra step:

- monitoring and generation of signals from the distributor of the artificial lung ventilation device (1).

The distributor of the artificial lung ventilation device (1) generates signals about the function performed by the distributor and the parameters of each artificial lung ventilation circuit (4). The volume of the breathing gas mixture, average or instantaneous lung ventilation, oxygen content in the breathing gas mixture, respiratory rate or other parameters are displayed for each patient. If the signals deviate from the norm, an alarm is generated. An alarm signal can be an excessive volume of the breathing gas mixture, excessive instantaneous ventilation of the lungs, or others. The signals of the distributor of the artificial lung ventilation device (1) can be presented on the screen of the control device (12), sound messages can be generated, the signals can be sent to a remote mobile device, computer cloud system or other computer tools.

In one of the embodiments of the invention, the total volume of the breathing gas mixture of the artificial lung ventilation apparatus (1) is 2000 ml. In this way, it is possible to safely ventilate four patients under a volume of 500 ml of breathing gas mixture. In case of a higher tidal volume requirement, it is necessary to reduce the tidal volumes of the other patient(s). The sum of volumes of the respirable gas mixture is limited by the instantaneous respiratory capacity of the ventilator (1), which is usually 2000 ml. Standard gas flow meters (F/ow-mefer) for non-invasive gas flow delivery are rated up to 15 l/min. In this case, to ventilate the lungs of four patients with 100% oxygen, a gas flow rate of 40 l/min is required. This is achieved by additionally unscrewing the needle regulator for the flow of the supplied gas mixture (2). When ventilating patients with a lower oxygen fraction, respiratory gas flow can be achieved using a venturi mechanism (10).

In order to illustrate and describe this invention, the above description of the most suitable embodiments is of a general nature - the description presents the measurements of the parts that make up the distributor of the artificial lung ventilation device (1), the materials, the method of connection, the amount of the parts themselves and other parameters, and the way of use and purpose of the device may differ - the description should be regarded as an illustration and not as a limitation.
