Description

TARIFNAME BIR YUKSEK DEBILI OKSIJEN TERAPI CIHAZI VE KONTROL YÖNTEMI Bu bulus, ortamdaki oksijen gazi oranindaki artisi tespit edebilen bir yüksek debili oksijen terapi cihazi ve kontrol yöntemi ile ilgilidir. Mekanik ventilatörler ve yüksek debili oksijen akisi saglayan HFO terapi cihazlari yogun bakim ünitelerinde kullanilmakla birlikte mobil, tasinabilir versiyonlarinin yayginlasmasiyla evlerde ve hasta nakli sirasinda da kullanilabilmektedir. Yogun bakimlarda oksijen kullanan birçok solunum destek cihazi bir arada çalismaktadir. Bu cihazlardan hastalara gönderilen oksijen gazinin bir kismi sürekli olarak ortama yayilmaktadir. Bunun yani sira yogun bakim ve hastane odalarinda solunum destek cihazlarina oksijen temin etmek üzere yapilan basinçli oksijen hatti baglantilarindan da ortama oksijen kaçagi riski bulunmaktadir. Cihazin, evlerde veya hastanin nakli sirasinda da kullaniminda ise basinçli oksijen tüpü baglantilarinda benzer oksijen kaçagi riski mevcuttur. Kapali bir ortamdaki oksijen konsantrasyonunun %25' in üzerine çikmasi durumu literatürde yangin tehlikesinin olustugu seklinde degerlendirilmektedir. Ortamdaki oksijen konsantrasyonundaki artis insanlar tarafindan fark edilememektedir. Dolayisi ile ortamdaki oksijen konsantrasyonunun yükselmesi ortamdaki kisilerce anlasilamamakta bu da oldukça ciddi yangin, patlama ve benzeri saglik ve güvenlik sorunlarinin ortaya çikmasina neden olmaktadir. Hava ve oksijen gazi karisim oraninin tutarli olabilmesi ve istenen seviyeye ayarlanabilmesi için hava ve oksijen akislarinin tutarli ölçümü gerekmektedir. Teknigin bilinen durumunda bu ölçüm için kullanilabilecek oksijen sensörü ve akis sensörleri bulunmaktadir. Akis sensörleri oldukça karmasik yapiya sahip olup cihaz maliyetine ciddi etkisi bulunmaktadir. Tek bir akis sensörü ve oksijen sensörü ile gaz karisimi ve toplam akisi ölçmek mümkündür ancak oksijen sensörleri genelde yavas tepki verdigi için sistemin performansini olumsuz etkilemektedir. Teknigin bilinen durumunda yer alan uygulamalarda oldugu gibi iki gaz hatti için ayri akis sensörlerinin kullanilmasi ise yüksek maliyetli bir çözüm olmaktadir. Teknigin bilinen durumunda yer alan EP2833953 sayili Avrupa Patentiinde, bir yüksek debili oksijen terapi cihazi açiklanmakta olup, cihaz, havayi basinçlandiran bir blower, blowerdan gelen havayi nemlendiren nemlendirici, nemlenen hava için bir çikis ve nemlendirici öncesinde yer alan ve akis üzerinden havanin içerigini algilayan bir ultrasound gaz sensörü içermektedir.

Havalandirma biriminden çikan havanin debisi ölçülen basinç sensörü ile oksijen gazi hava karisiminin debisini ölçen akis sensörü tarafindan toplanan veriler karsilastirilarak dis ortamdaki oksijen gazi seviyesi tespit edilmektedir. Basinç sensörü, bir ucu havalandirma birimine açilan baglanti kanalina konulandirilmaktadir. Karisimin oksijen konsantrasyonu ise bir oksijen sensörü ile ölçülmektedir. Bulusun bir uygulamasinda yüksek debili oksijen terapi cihazi, bir basinç düzenleyicisi, basinç düzenleyicisi üzerinden girise geçen oksijen gazinin ilerledigi bir oksijen gazi hatti ve bu hat üzerinde, oksijen gazinin debisinin ayarlandigi bir vana içermektedir.

Bulusun uygulamasinda basinçli oksijen kaynagindan çikan oksijen gazi yüksek debili oksijen terapi cihazinin girisine bir basinç düzenleyicisinden geçerek ulasmaktadir. Oksijen gazi hattina geçen oksijen gazinin debisi vana araciligi ile ayarlanmaktadir. Ayni anda havalandirma birimi araciligi ile açikliktan geçerek ortamdan alinan hava, filtreden geçerek yüksek debili oksijen terapi cihazi içine alinmaktadir. Havalandirma birimi tarafindan cihaz içine alinan ortam havasi, karisim hattina ulasmadan önce, havalandirma birimi ile karisim hatti arasina konumlandirilan ve havalandirma biriminden cihaz içine giren havanin debisinin ölçüldügü basinç sensöründen geçmekte ve oksijen gazi hattinin da açildigi ve oksijen gazi ile havanin karistigi karisim hattina ulasmaktadir. Oksijen gazi hava karisiminin debisi de, karisim hattinda yer alan akis sensörü tarafindan ölçülmektedir. Basinç sensörünün ölçtügü havanin debisi ile akis sensörü tarafindan ölçülen oksijen gazi hava karisiminin debisi karsilastirilarak dis ortamdaki oksijen gazi seviyesi tespit edilmektedir. Bulusun bir uygulamasinda akis sensöründen geçen oksijen gazi hava karisimi, karisimin oksijen konsantrasyonunu ölçen oksijen sensörü üzeriden geçmekte ve tahliye hattina ulasarak dis ortamdaki hasta devresi veya nemlendirici ve benzeri aktarilmaktadir. Bulusun bir uygulamasinda havanin debisi, atmosfer basinci ile basinç sensörü tarafindan ölçülen ortam havasinin basinç degeri arasindaki farktan hesaplanmaktadir.

Eger oksijen gazi debisi olmasi gereken oksijen gazi debisinden düsük ise dis ortamin oksijen seviyesinin %21 degerinden yüksek olduguna kanaat getirilerek uyari verilmektedir.

TR TR DESCRIPTION A HIGH FLOW OXYGEN THERAPY DEVICE AND CONTROL METHOD This invention relates to a high flow rate oxygen therapy device and control method that can detect the increase in the oxygen gas rate in the environment. Although mechanical ventilators and HFO therapy devices that provide high-flow oxygen flow are used in intensive care units, they can also be used at home and during patient transport as mobile, portable versions become more common. Many respiratory support devices that use oxygen work together in intensive care units. Some of the oxygen gas sent to patients from these devices is constantly emitted into the environment. In addition, there is a risk of oxygen leakage to the environment from pressurized oxygen line connections made to supply oxygen to respiratory support devices in intensive care and hospital rooms. There is a similar risk of oxygen leakage in pressurized oxygen cylinder connections when the device is used at home or during patient transportation. If the oxygen concentration in a closed environment exceeds 25%, it is evaluated in the literature as a fire hazard. The increase in oxygen concentration in the environment cannot be noticed by humans. Therefore, the increase in oxygen concentration in the environment cannot be understood by people in the environment, which causes serious fires, explosions and similar health and safety problems. In order for the air and oxygen gas mixing ratio to be consistent and adjusted to the desired level, consistent measurement of air and oxygen flows is required. In the state of the art, there are oxygen sensors and flow sensors that can be used for this measurement. Flow sensors have a very complex structure and have a serious impact on the device cost. It is possible to measure gas mixture and total flow with a single flow sensor and oxygen sensor, but since oxygen sensors generally respond slowly, they negatively affect the performance of the system. Using separate flow sensors for two gas lines, as in the state of the art applications, is a high-cost solution. In the European Patent numbered EP2833953, which is in the state of the art, a high flow rate oxygen therapy device is described, and the device consists of a blower that pressurizes the air, a humidifier that humidifies the air coming from the blower, an outlet for the humidified air and an ultrasound device located before the humidifier and detecting the content of the air through the flow. Includes gas sensor. The purpose of this invention is to realize a high-flow oxygen therapy device and control method that can detect the increase in the oxygen gas rate in the environment. The high-flow oxygen therapy device, which is realized in order to achieve the purpose of this invention and defined in the first claim and the claims attached to this claim, consists of a gas inlet connected to the oxygen gas source, a ventilation unit that draws ambient air, a mixing line where oxygen and air are mixed, a gas inlet located in the mixing line and oxygen gas. It includes a flow sensor that measures the flow rate of the air mixture and a pressure sensor placed before the ventilation unit and the mixing line, allowing the flow rate of the air coming out of the ventilation unit to be measured. The oxygen gas level in the outdoor environment is determined by comparing the data collected by the pressure sensor, which measures the flow rate of the air coming out of the ventilation unit, and the flow sensor, which measures the flow rate of the oxygen gas-air mixture. The pressure sensor is placed in the connection channel, one end of which opens to the ventilation unit. The oxygen concentration of the mixture is measured with an oxygen sensor. In one embodiment of the invention, the high-flow oxygen therapy device includes a pressure regulator, an oxygen gas line through which the oxygen gas passes to the inlet through the pressure regulator, and a valve on this line through which the flow rate of the oxygen gas is adjusted. In one embodiment of the invention, the high-flow oxygen therapy device includes an opening through which ambient air is drawn into the device through the ventilation unit and a filter through which the ambient air drawn through the opening is purified from dust and similar impurities. In the application of the invention, the oxygen gas coming out of the pressurized oxygen source reaches the inlet of the high-flow oxygen therapy device through a pressure regulator. The flow rate of oxygen gas passing into the oxygen gas line is adjusted through the valve. At the same time, the air taken from the environment through the opening through the ventilation unit is passed through the filter and taken into the high-flow oxygen therapy device. Before reaching the mixing line, the ambient air taken into the device by the ventilation unit passes through the pressure sensor located between the ventilation unit and the mixing line, where the flow rate of the air entering the device from the ventilation unit is measured, and reaches the mixing line, where the oxygen gas line is opened and oxygen gas and air are mixed. The flow rate of the oxygen gas air mixture is measured by the flow sensor located in the mixture line. The oxygen gas level in the outdoor environment is determined by comparing the air flow rate measured by the pressure sensor with the flow rate of the oxygen gas-air mixture measured by the flow sensor. In an embodiment of the invention, the oxygen gas-air mixture passing through the flow sensor passes over the oxygen sensor that measures the oxygen concentration of the mixture and reaches the discharge line and is transferred to the patient circuit or humidifier in the external environment or the like. In an embodiment of the invention, the air flow rate is calculated from the difference between the atmospheric pressure and the pressure value of the ambient air measured by the pressure sensor. In another embodiment of the invention, the flow rate of the oxygen gas air mixture determined by the user and the oxygen concentration in the oxygen gas mixture are provided by adjusting the air and oxygen gas flow rates using the flow sensor and oxygen sensor data. In an embodiment of the invention, the oxygen gas flow rate that should be in the oxygen gas air mixture is calculated according to the flow rate and oxygen concentration value set by the user. In the preferred embodiment of the invention, the flow rate of oxygen gas is found by subtracting the flow rate of the ambient air measured by the pressure sensor from the flow rate of the oxygen gas air mixture measured by the flow sensor and is compared with the required oxygen gas flow rate. If the oxygen gas flow rate is lower than the required oxygen gas flow rate, it is concluded that the oxygen level of the external environment is higher than 21% and a warning is given. In one embodiment of the invention, it is a control method for the high-flow oxygen therapy device defined above, which includes a flow sensor located in the mixing line and measuring the flow rate of the oxygen gas-air mixture, and a pressure sensor placed before the ventilation unit and the mixing line, allowing the flow rate of the air coming out of the ventilation unit to be measured. It includes the steps of detecting the oxygen gas level in the external environment by comparing the flow rate of the air measured by the pressure sensor and the flow rate of the oxygen gas air mixture measured by the flow sensor. In this embodiment of the invention, the control method includes the step of calculating the difference between the atmospheric pressure and the pressure value of the ambient air measured by the pressure sensor. The control method of the invention also adjusts the flow rate of the oxygen gas air mixture determined by the user and the oxygen concentration in the oxygen gas mixture, adjusting the air and oxygen gas flow rates using the flow sensor and oxygen sensor data, and adjusting the oxygen gas air mixture according to the flow rate and oxygen concentration value set by the user. It includes the steps of calculating the oxygen gas flow rate. In another application of the control method of the invention, by subtracting the flow rate of the ambient air measured with the pressure sensor from the flow rate of the oxygen gas air mixture measured with the flow sensor, the oxygen gas flow rate is found and compared with the required oxygen gas flow rate. If the oxygen gas flow rate is lower than the required oxygen gas flow rate, the oxygen gas flow rate of the external environment is determined. It includes the steps of determining that the level is high and giving a warning. With this invention, the oxygen level in the environment is constantly controlled, preventing fire and similar negativities in case of a possible increase in concentration. Thanks to the use of a pressure sensor, more precise flow measurement and control can be made and the set flow rate and oxygen rate can be reached faster. As a result, great cost advantages are achieved without sacrificing performance. A high flow oxygen therapy device and control method implemented to achieve the purpose of this invention are shown in the attached figures, and these figures; Figure 1 - is the view of a high flow oxygen therapy device. Figure 2 - Detail view of the high flow oxygen therapy device. Figure 3 - is the view of a ventilation unit. Figure 4 - Detail view of the ventilation unit.

The flow rate of the air coming out of the ventilation unit (3) is measured with the pressure sensor (10). The flow rate of the oxygen gas air mixture is measured by the flow sensor (9) located in the mixture line (7). The oxygen gas level in the external environment is determined by comparing the flow rate of the air measured by the pressure sensor (10) with the flow rate of the oxygen gas-air mixture measured by the flow sensor (9). In an embodiment of the invention, the high-flow oxygen therapy device (1) contains a connection channel (14) with one end opening to the ventilation unit (3) and a pressure sensor (10) at the other end (Figure 3 and Figure 4). In the preferred embodiment of the invention, the high flow rate oxygen therapy device (1) consists of an oxygen gas sensor (8) that measures the oxygen concentration of the mixture and reaches the oxygen gas air mixture passing through the flow sensor (9) and the mixture passing through the oxygen gas sensor (8) reaches the device (1). It contains a discharge line (11) that allows it to be discharged to the outside. In an embodiment of the invention, the high-flow oxygen therapy device (1) consists of a pressure regulator (12), an oxygen gas line (6) along which the oxygen gas passing through the pressure regulator (12) to the inlet (2), and on this line (6), the oxygen gas is transferred to the inlet (2). It contains a valve (13) through which the flow rate is adjusted.

The flow rate of oxygen gas passing into the oxygen gas line (6) is adjusted via valve (13). At the same time, the air taken from the environment through the opening (4) through the ventilation unit (3) is taken into the high-flow oxygen therapy device (1) by passing through the filter (5). Before the ambient air taken into the device (1) by the ventilation unit (3) reaches the mixing line (7), the flow rate of the air positioned between the ventilation unit (3) and the mixing line (7) and entering into the device (1) from the ventilation unit (3) is determined. It passes through the pressure sensor (10) where it is measured and reaches the mixing line (7), where the oxygen gas line (6) is also opened and the oxygen gas and air are mixed. The flow rate of the oxygen gas air mixture is measured by the flow sensor (9) located in the mixture line (7). By comparing the flow rate of the air measured by the pressure sensor (10) and the flow rate of the oxygen gas air mixture measured by the flow sensor (9), the oxygen gas level in the external environment is determined (Figure. In an embodiment of the invention, the oxygen gas air mixture passing through the flow sensor (9) is measured by the oxygen concentration of the mixture.

It includes the steps of calculating the oxygen gas flow rate that should be in the oxygen gas-air mixture. In another application of the control method of the invention, by subtracting the flow rate of the ambient air measured by the pressure sensor (10) from the flow rate of the oxygen gas air mixture measured by the flow sensor (9), the flow rate of oxygen gas is found and compared with the required oxygen gas flow rate, and the oxygen gas flow rate is calculated as the required oxygen gas flow rate. If it is lower than the flow rate, it includes the steps of giving a warning by concluding that the oxygen level of the external environment is high. With this invention, the oxygen level in the environment is constantly controlled, preventing fire and similar negativities in case of a possible increase in concentration. Thanks to the use of the pressure sensor (10), more precise flow measurement and control can be made and the set flow rate and oxygen rate can be reached faster. As a result, a great cost advantage is achieved without sacrificing performance.TR TR
