Description

[0001] A HOME TYPE MECHANICAL VENTILATOR THAT USES OXYGEN SOURCE CAPACITY WITHOUT LOSS AND DELIVERS TO THE PATIENT

[0002] Field of the Invention

[0003] The invention relates to a mechanical ventilator used to artificially maintain respiratory function.

[0004] In particular, the invention relates to a household mechanical ventilator used for continuous or intermittent ventilation support of patients, in which the capacity is wasted or not used during expiration (exhalation), generally storing the amount of oxygen supplied or stopped to the environment and the entire amount of oxygen entering from the source, delivering it to the patient without wasting any unit of oxygen capacity and providing high oxygen saturation to the patient.

[0005] State of the art

[0006] Mechanical ventilators are devices used to artificially maintain respiratory function in cases where the lung cannot perform the vital function of breathing for any reason. These devices are for adults and children with a tidal volume of at least 50 ml in e.g. intensive care, pulmonology, neurology, emergency areas and at home.

[0007] Mechanical ventilators used today are divided into two types: hospital type and home type. The home type mechanical ventilator has additional pressure-controlled, volume- controlled and flow-controlled ventilation modes. Ventilation can be performed invasively (e.g. via tracheostomy) or noninvasively (via ventilation mask and HFNC in HFOT mode). The home type mechanical ventilator has the technical conditions to be operated with a single hose system with an expiratory valve or with two hose systems when necessary. However, home mechanical ventilators do not require an external air supply. Instead, the fan (blower) inside them increases the pressure of the ambient air and creates a pressurized air output. The pressure at the outlet is controlled by the fan motor speed and there are no additional valves at this point. Oxygen is added to this pressure-controlled air through the oxygen inlet and delivered to the patient. There is also only one valve on the oxygen side. The lack of sensors and valves at this point and the fact that the pressure control is carried out with the fan motor speed results in the oxygen concentration in the outlet air mixture not reaching high levels. Oxygen concentrators are also very important for home type use. These devices are 5LPM and 10LPM 95% oxygen producing devices. For example, a patient breathing 5L Minute Volume breathing with a 5LPM concentrator supported home ventilator device can only reach 50% oxygen concentration. This is because oxygen is wasted during expiration (exhalation) and is usually given to the environment.

[0008] Another type of mechanical ventilator in the state of the art is hospital-type ventilators. Hospital-type mechanical ventilators require a supply of compressed air and oxygen to operate. With the help of proportional and normal valve systems and sensors at both inlets, the mixture of oxygen and air is made in the desired ratio and brought to the appropriate pressure level. Since both sources are already high pressure, only pressure regulation is performed to reduce the pressure to the relevant pressure level. In addition, no mechanism is needed to create pressure. Since both sources are high pressure, the desired oxygen concentration level (100%) can be achieved with the help of valves at the source inlets. Of course, this requires a very high consumption of oxygen supply. In addition, the need for a separate air source to operate and the use of a large number of valve systems and sensors (cost and production difficulty) are the biggest disadvantages.

[0009] As a result of the researches made on the subject, document No FR2999437A1 is encountered. The relevant document relates to a medical ventilator for ventilating the patient at home by providing ambient air and oxygen to the patient. The current technique comprises a sensor that measures the amount of oxygen saturation delivered to the patient. However, there is no development aimed at using the entire amount of oxygen coming from the source.

[0010] Another document encountered in the literature is the patent application numbered TR 2020 / 05939. The relevant document relates to a non-invasive ventilation device that can be used in home and hospital environments and allows air to enter the lungs through the mouth and nose. The current technique aims to remove the phlegm that the patient cannot expel from the lungs. However, there is no development aimed at using the entire amount of oxygen coming from the source.

[0011] As a result due to the abovementioned disadvantages and the insufficiency of the current solutions regarding the subject matter, a development is required to be made in the relevant technical field. Aim of the Invention

[0012] The present invention aims to solve the abovementioned disadvantages by being inspired from the current conditions.

[0013] The main aim of the invention is to provide a home type mechanical ventilator that eliminates the amount of oxygen that is wasted during expiration (exhalation) or the amount of oxygen that is usually given or stopped to the environment where the capacity is not used, and that stores all of the oxygen entering from the source and delivers it to the patient without loss and without wasting any unit.

[0014] Another aim of the present invention is to ensure that all the oxygen taken from the oxygen source is collected in the lower and upper air ducts thanks to the valve that is closed during the exhalation phase. In this way, by opening the valve during breathing, the oxygen accumulated in these ducts is delivered to the patient by sweeping the oxygen coming from the duct, so that a 100% amount of oxygen is delivered to the patient, full capacity utilization of the oxygen source and higher oxygen saturation is provided to the patient.

[0015] Another aim of the present invention is to offer a mechanical ventilator that contains fewer components than existing home devices, is simple, has low production costs and provides much less oxygen consumption.

[0016] In order to fulfil the above-mentioned purposes, the present invention is a home type mechanical ventilator providing oxygen support to patients in cases where the lung cannot fulfil the respiratory function, which is a vital function for any reason, and artificially maintaining breathing, comprising

[0017] • A fan that creates compressed air,

[0020] • Oxygen inlet block where oxygen enters the ventilator, which provides oxygen flow towards the flow to the environment or storage area during expiration, and

[0040] Detailed Description of the Invention

[0041] In this detailed description, the preferred embodiments of the inventive ventilator (1) are described by means of examples only for clarifying the subject matter.

[0042] The mechanical ventilator (1), which is the subject of the invention, shown in Figure 3, in its most basic form comprises a fan (14) that creates compressed air and an outlet pipe block (16) that carries oxygen to the patient side. In addition, it comprises a suction section (12) through which the compressed air produced by the fan (14) passes, that allows the oxygen overflowing from the upper air ducts (10) and lower air ducts (11) and fan (14) outlet ducts where the oxygen is stored during expiration to be stored and drawn by the fan during suction.

[0043] The inventive mechanical ventilator (1), which provides oxygen support to patients in cases where the lung cannot fulfil the respiratory function, which is a vital function, for any reason, and ensures that breathing is maintained artificially, also includes an oxygen inlet block (13), through which oxygen enters the ventilator, and which provides oxygen flow to the environment during expiration or oxygen flow towards the storage area. In addition, it comprises inspiratory valve (15), which provides oxygen storage in the upper air ducts (10), the lower air ducts (11) and the suction section (12), which are closed during expiration (exhalation) and separate the patient and the fan (14) side, becomes open during inspiration (breathing) and allows oxygen to enter the patient along with the stored oxygen. In one embodiment of the invention, the mechanical ventilator (1) comprises oxygen source inlet holes (18) connecting the oxygen supply to the oxygen inlet block (13). In addition, the fan cabin connection silicone (17), which provides the oxygen inlet block (13) connection of the fan cabin, and the sensors (19) located in the outlet pipe block (16), which measure the pressure, flow, volume oxygen concentration of the air going to the patient.

[0044] The most important aim of the inventive mechanical ventilator (1) is to store all of the oxygen entering from the source and to provide high saturation air to the patient without wasting any unit of the oxygen capacity without loss of capacity and thus to provide high saturation air to the patient with full capacity oxygen utilization. It is able to achieve this with simplicity and much less oxygen consumption that cannot be compared with hospital-type devices, and with less components, cost and ease of production than existing home-type devices. For example, a patient breathing 5L Minute Volume breathing with a 5LPM concentrator supported home ventilator device can only reach 90-95% oxygen concentration. With the use of an oxygen cylinder, 100% oxygen concentration can be achieved.

[0045] The operating principle of the mechanical ventilator (1) is as follows:

[0046] During exhalation, the inspiratory valve (15) is closed and the air flow towards the patient is zero. The fan (14) rotates in the PEEP pressure cycle and produces this pressure. There is a continuous flow from the oxygen source inlet holes (18) connected to the oxygen inlet block (13), and oxygen flows from the source into the lower pressure oxygen inlet block (13). Since one side of the block is closed by the inspiratory valve (15), in the other direction (fan (14) direction), oxygen starts to fill the oxygen inlet block (13), fan cabin connection silicone (17), upper air ducts (10), lower air ducts (11) and suction section (3) volumes respectively. This volume filled with oxygen is very important. The cross-sectional area should be large enough not to create resistance to the fan flow, and small enough that the oxygen will not be trapped in the pockets by turbulence and will be pushed by the air flow created by the fan. This is between 255 mm2and 280 mm2. A larger area will cause the oxygen to be compressed and not mixed into the air. In addition, the amount of oxygen filling here is determined by the oxygen rate at the source and the expiration time.

[0047] When the breathing phase comes, the fan (14) increases its speed and creates air flow. The inspiratory valve (15) opens and air flow begins in the direction of the patient. The air formed at the outlet end of the fan (14) passes through the lower air ducts (11), upper air ducts (10), fan cabin connection silicone (17) and oxygen inlet block (13) respectively. During this transition, it sweeps up the oxygen it has added and delivers it to the device outlet and the patient. Since the flow in the oxygen source is not interrupted at the same time, this supports the oxygen concentration. In this way, no milliliter of the oxygen coming from the source is wasted and_ delivered to the patient. In this way, the use of oxygen supply equal to the patient's minute volume consumption ensures that the patient breathes with 100% oxygen.
