Description
Oxygen Concentrator Technical Field
The present invention is related to oxygen concentrator that decomposes and concentrates oxygen in the air and puts thereof into use for the patients. The present invention is especially related to oxygen concentrator that decomposes oxygen in the air, adjusts the oxygen level automatically by receiving feedback from the patient, and balances the rate of receiving oxygen by the patient automatically to be used in health sector.
State of Art
In the state of art, oxygen is generated in a proper way for human health thanks to the molecular sieves of oxygen concentrator. During the generation of oxygen, the compressor of the device takes in the air from its surroundings. The air taken is transferred into the tanks in which molecular sieve is provided. Oxygen is decomposed within the tank. After going through several processes, the oxygen is delivered to the patient. The air that we breathe in the atmosphere consists of 21 % oxygen (02), 78% nitrogen (N2), 0.9% argon (Ar) and 0.1 % other gases. Oxygen concentrators decompose the gases in the ambient air. Oxygen that is pure 95% (± 3) is generated by means of the system called molecular sieve. Decomposition of oxygen is performed when the compressor produced high pressure within the tank. In order to produce said pressure, the compressor absorbs the air in the atmosphere in a powerful manner. During said absorption, it also takes in lots of particles in the atmosphere. Said particles shortens the service life of compressor. Moreover, when said particles fill into the tubes including molecular sieves and accumulated therein, oxygen generation of the device decreases. What's worse is that said dirty substances accumulated within the device are delivered to the patient in a short time. Said particles taken into the body directly will pose a risk of infection in the patient. Especially, the devices used in the hospital directly deliver the infections called nosocomial infections that are present in the hospital and unrecoverable, to the patients. Therefore, the patient gets worse rather than being treated. The US patent document numbered US2017087326 and titled Oxygen concentrator systems and methods" is an example of oxygen concentrator. The present invention is a method for an oxygen concentrator to provide a gas enriched in terms of oxygen to the user and a
compression system consisting of at least two cans, gas separation adsorbent disposed in at least two canisters, wherein the gas separation adsorbent separates at least some nitrogen from air in the canister to produce oxygen enriched gas, and at least one compressor coupled to at least one canister, and a method thereof are disclosed. However, feedback received from the patient and proportional adjustments made in accordance with said feedback are not disclosed.
As a result, the need for oxygen concentrator that decomposes oxygen in the air, adjusts the oxygen level automatically by receiving feedback from the patient, and balances the rate of receiving oxygen by the patient automatically in order to be used in health sector, and insufficiencies of the present solutions have made it necessary to make an improvement in the related technical field.
Objects of the Present Invention The present invention is related to oxygen concentrator that meets the abovementioned requirements, eliminates the possible disadvantages and offers some additional advantages.
The primary object of oxygen concentrator according to the present invention is to deliver oxygen generated to the patient in an accurate and healthy manner thanks to the feedback received from the patient. Oxygen is generated in a proper way for human health thanks to the molecular sieves. During the generation of oxygen, the compressor of the device takes in the air from its surroundings and transfers thereof into the tanks in which molecular sieve is positioned. Oxygen is decomposed within the tank and delivered to the patient by going through several processes. Oxygen concentrator receives feedback from the patient. The feedback received is analyzed by circuit board. In accordance with the analysis report, the circuit board changes the oxygen ratio by means of proportional valve. The patient receives oxygen in a needed ratio rather than a fixed amount of oxygen. When the feedback member detects that oxygen reaches the adequate level, the oxygen ratio is adjusted. Another object of the present invention is to filter the particles within the air taken from the surroundings and prevent thereof from entering into the respiratory system of the patient. Moreover, the filter prevents said particles from entering oxygen concentrator and enables the device to function for longer time and in a healthy manner. The particles and other foreign substances within the air absorbed by the compressors are detained by the filter. They are not allowed to enter the oxygen concentrator. Thus, the tanks generating oxygen remain clean.
In order to achieve the abovementioned objects, an oxygen concentrator that decomposes oxygen in the air, adjusts the oxygen level automatically by receiving feedback from the patient, and balances the rate of receiving oxygen by the patient automatically in order to be used in health sector, has been developed. The oxygen concentrator developed that feeds oxygen to the patients who have respiratory pathology, transfers oxygen generated by the compressor, which functions with the power received from the inlet of power cable, by decomposing the air absorbed in zeolite beds, to the oxygen tank and delivers for the use of patient and comprises a body, over which is positioned at least one circuit board that analyzes the data received from the feedback member and pressure sensor and produces signal for increasing and decreasing the oxygen level, and at least one proportional valve increasing and decreasing the oxygen level thanks to the signal of circuit board.
The structural and characteristic features and all the advantages of the present invention will be more clearly understood thanks to the figures below and the detailed description written with reference to those figures and therefore, the evaluation needs to be done by taking said figures and the detailed description into consideration.

Detailed Description of the Invention
Figure 1 is the perspective view of oxygen concentrator (10) according to the present invention. Oxygen concentrator (10) has a body (1 1 ). There are wheels (19) positioned on the body (1 1 ). The wheels (19) enable the oxygen concentrator (10) to be moved easily and to be transported as desired. Thanks to the wheels (19), oxygen concentrator (10) is mobilized. The air diverter (17) positioned on the body (1 1 ) enables the air coming out of the fan (18) or exhaust (23) to be directed. Therefore, the air is prevented from causing disturbance. Moreover, the air diverter (17) enables the air to be directed downwards and prevents the fans from getting dirty and dusty. Figure 2 is the sectional view of oxygen concentrator (10) according to the present invention. The power received from network line and/or another power supply, is provided by means of power cable inlet (26) positioned on the body (1 1 ). Thus, the power required for oxygen concentrator (10) is provided. Compressor (28) is operated with the power supplied. The air arriving the compressor (28) passes through the filter cassette (21 ). The filter cassette (21 ) cleans the foreign substances and particles in the air that passes through the filter. Oxygen concentrator (10) remains clean thanks to the filter cassette (21 ). Thus, oxygen concentrator functions efficiently and/or for longer time. The air coming out of the compressor (28) is transferred to the valve group (22). The valve group (22) transfers the air received to the zeolite bed.
Figure 4 is the perspective view of oxygen tank (24) of oxygen concentrator (24) according to the present invention. The air arriving the zeolite beds (25) is decomposed. Zeolites function as molecular sieves or filter tools that grasp and detain positively charged atoms, ions and/or other components and remove thereof from the system in which they are provided. They are structurally similar to clay minerals. Although both of them belong to alumina silicate group, their crystal structures differ. 78% nitrogen (N2) provided within the air arriving with the pressure is
detained by zeolite beds (25) and 95%(± 3) pure oxygen is transferred to oxygen tank (24). When nitrogen detained in zeolite bed (25) has the required saturation, it is removed from the system by means of exhaust (23). Figure 3 is the sectional view of oxygen concentrator (10) according to the present invention. Compressor (28) or the system may get heated while they are functioning. Fan (18) is positioned on the body (1 1 ) in order to cool the oxygen concentrator (10) and compressor (28). Fan (18) or fans (18) remove/removes the hot air provided in the body (1 1 ) from the system by means of air diverter (17). Oxygen that is generated, is transferred to the proportional valve (27) from the oxygen tank (24) by means of proportional valve inlet (27a). The proportional valve (27) increases or decreases the oxygen passage in accordance with the signal received from circuit board (20). The feedback member (30) coupled to the patient measures the oxygen saturation of the patient. It sends the measurement results to the circuit board (20) by means of feedback member inlet (31 ). Circuit board (20) analyzes the information it receives from the feedback member (30). At the same time, the pressure sensor (29) measures the amount of pressure air delivered to the patient. The pressure sensor (29) also transfers the measurements of pressure air amount to the circuit board (20). The circuit board (20) analyzes said feedbacks it receives and makes the proportional valve (27) adjust the oxygen ratio. Oxygen having adjusted ratio is transferred to the pressure sensor (29) by means of valve outlet (27b) and delivered to the patient therefrom.
Figure 5 is the sectional view of control panel (12) of oxygen concentrator (10) according to the present invention. Control panel (12) enables the oxygen level and/or pressure amount to be adjusted manually. Display screen (13) is provided on the control panel (12). Display screen (13) shows the oxygen amount and/or pressure air amount. The adjustment buttons (15) positioned on the control panel (12) enable up and down movements in the menu provided on the display screen (13). Confirm button (14) is used to select the desired menu member. After completing all of the manual selections, oxygen concentrator is adjusted and started manually by means of start button (16) positioned on the control panel (12) again. Moreover, start button (16) enables the oxygen concentrator (10) to be started or stopped.
