[0003] In clinical practice, many patients require long-term oxygen therapy, such as those with chronic obstructive pulmonary disease (COPD). This is a common respiratory disease, and patients with COPD typically require long-term oxygen therapy to maintain blood oxygen saturation. For this type of disease, high-flow oxygen therapy is an effective form of oxygen therapy, providing a stable, high-flow-rate mixture of gas (oxygen and air) to improve the patient's respiratory function.

[0081] In the following description, many technical details are presented to help the reader better understand this application. However, those skilled in the art will understand that the technical solutions claimed in this application can be implemented even without these technical details and various variations and modifications based on the following embodiments.

[0082] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0083] This application discloses a high-flow oxygen detection device, such as Figure 1 As shown, the system includes an oxygen inlet pipe 101, an air inlet pipe 102, a mixing input pipe 103, a flow sensor 201, a regulating valve 202, an oxygen concentration sensor 203, a humidification device 104, and an air outlet pipe 105. One end of the oxygen inlet pipe 101 is the oxygen inlet, and the other end is connected to one end of the mixing input pipe 103 to form a first connection point 301. From the oxygen inlet to the first connection point 301, the diameter of the oxygen inlet pipe 101 gradually decreases and then gradually increases to form a Venturi tube structure.

[0084] One end of the air inlet pipe 102 is the air inlet, and the other end is connected to the narrowest part of the oxygen inlet pipe 101 to form a second connection 302. The oxygen inlet pipe 101 is connected to an external oxygen source. As the oxygen source continuously outputs oxygen, oxygen will flow into the oxygen inlet pipe 101. The Venturi tube structure will create a negative pressure at the narrowest part of the pipe diameter, which facilitates the intake of external air and mixing with oxygen. After the gas is mixed, it enters the mixing input pipe 103, thereby producing a good suction and mixing effect.

[0085] A flow sensor 201 and a regulating valve 202 are respectively installed at the oxygen inlet and the air inlet to monitor and regulate the flow of oxygen and air in real time, ensuring that the mixed gas ratio meets the treatment requirements; an oxygen concentration sensor 203 is installed at the first connection 301 to monitor the concentration of input oxygen in real time and ensure stable oxygen quality; the flow sensor 201 and the oxygen concentration sensor 203 are equipped with or associated with a display device 204 for easy real-time data viewing.

[0086] The other end of the mixing inlet pipe 103 is connected to a humidifier 104, which includes a humidification chamber 401 and a humidification component 402. The humidification chamber 401 is externally connected to or internally equipped with the humidification component 402. One end of the outlet pipe 105 is connected to the humidification chamber 401, and the other end is connected to an oxygen mask or nasal cannula. The humidifier 104 facilitates increasing the humidity of the mixed gas, making oxygen inhalation more comfortable for patients. Because this application has the main functions of oxygen and air ratio adjustment and humidification, it can, to a certain extent, replace a sophisticated and expensive high-flow oxygen concentrator while taking cost into consideration.

[0087] In one embodiment, the oxygen inlet pipe 101 is detachably connected to the first connection 301 via a flange;

[0088] In one embodiment, the air inlet pipe 102 is detachably connected to the second connection 302 via a flange; the detachable flange design makes the gas-absorbing part of the device easy to clean and replace, improving cleanliness.

[0089] In one embodiment, the regulating valve 202 is a mechanical control structure.

[0090] In one embodiment, the humidification component 402 is a mechanically controlled structure. Mechanical control requires manual adjustment of the regulating valve 202 and the humidification component 402 based on current data, but it is less expensive.

[0091] In one embodiment, the regulating valve 202 is an electrically controlled structure.

[0092] In one embodiment, the humidification component 402 is an electrically controlled structure. The electrically controlled structure allows for more convenient adjustment of the regulating valve 202 and the humidification component 402 based on current data. This adjustment can be manual or automatically made by the controller 501 based on the difference between the current value and preset treatment parameters (treatment parameters include oxygen flow rate, air flow rate, oxygen concentration, pressure, humidity, or temperature, etc.). For example, when the oxygen concentration sensor 203 detects that the oxygen concentration in the mixed gas is higher than the upper limit, the regulating valve 202 is automatically adjusted to reduce the oxygen flow rate; or when it is lower than the lower limit, the regulating valve 202 is automatically adjusted to increase the oxygen flow rate.

[0093] In one embodiment, the humidifier 104 or the air outlet pipe 105 is also equipped with a pressure sensor 205 to monitor the pressure of the output gas in real time and ensure that the pressure of the gas inhaled by the patient is stable.

[0094] In one embodiment, the humidifier 104 or the air outlet pipe 105 is also equipped with a humidity sensor 206 to monitor the humidity of the output gas in real time and ensure that the humidity of the gas inhaled by the patient is stable.

[0095] In one embodiment, the humidifier 104 or the outlet pipe 105 is also equipped with a temperature sensor 208 to monitor the temperature of the output gas in real time and ensure that the temperature of the gas inhaled by the patient is stable.

[0096] In one embodiment, such as Figure 2 and Figure 3 As shown, the humidifier 104 or the air outlet pipe 105 is also equipped with a pressure sensor 205 and a humidity sensor 206.

[0097] In other words, in one embodiment, the humidification device 104 or the air outlet pipe 105 may be equipped with any one or two of the following: pressure sensor 205, humidity sensor 206, or temperature sensor 208.

[0098] In one embodiment, the air intake end of the air intake pipe 102 is connected to an air filter 207. The air filter 207 can filter impurities, dust, and other pollutants in the air, ensuring the quality of the air mixed.

[0099] In one embodiment, such as Figure 4 As shown, a baffle 209 is provided in the oxygen inlet pipe from the second connection 302 to the first connection 301 or in the mixing input pipe 103. The baffle 209 can make oxygen and air mix thoroughly before flowing into the humidification chamber 401, thereby improving the mixing uniformity.

[0100] In one embodiment, an inhalation drive device 210 is provided in the oxygen inlet pipe from the second connection 302 to the first connection 301 or in the mixing input pipe 103. Figures 1 to 5 (Not shown in the image). The suction drive device 210 can enhance the suction of oxygen and air, increasing the flow rate.

[0101] In one embodiment, the high-flow oxygen detection device is a portable device, and the bottom of the humidification device 104 is equipped with wheels. Figures 1 to 5 (Not shown in the image). The rollers facilitate the movement of the high-flow oxygen detection device, allowing it to be moved as needed to follow the patient's movements.

[0102] In one embodiment, the humidifier 104 or the air outlet pipe 105 is further provided with a pressure sensor 205, a humidity sensor 206, and a temperature sensor 208. In one embodiment, the pressure sensor 205, the humidity sensor 206, and the temperature sensor 208 are associated with the display device 204.

[0103] In one embodiment, the flow sensor 201, oxygen concentration sensor 203, pressure sensor 205, humidity sensor 206, and temperature sensor 208 each have their own display device 204.

[0104] In one embodiment, such as Figure 5 As shown, it also includes an alarm device 502 and an input device 503. The alarm device 502 is used to sound an alarm when an abnormal value is detected, and the input device 503 is used to input and set treatment parameters.

[0105] In one embodiment, such as Figure 1 As shown, the oxygen inlet pipe 101 and the mixing input pipe 103 are horizontally connected. The humidification chamber 401 is cylindrical in shape, and the mixing input pipe 103 is horizontally connected to the side wall of the humidification chamber 401. The horizontal connection facilitates gas mixing and reduces impact.

[0106] The air inlet pipe 102 is vertically connected to the lower part of the narrowest point of the oxygen inlet pipe 101;

[0107] The humidification chamber 401 is connected to the humidification component 402 at the bottom; the humidification component being located at the bottom allows the humidification medium to be evenly distributed at the bottom of the chamber, and then the air is humidified from bottom to top through evaporation or other humidification methods, thereby improving humidification efficiency and uniformity.

[0108] One end of the air outlet tube 105 is vertically connected to the top of the humidification chamber 401, and the other end is bent to a horizontal direction. The vertical connection of one end of the air outlet tube to the top of the humidification chamber can make the most of the natural upward trend of the gas in the chamber, while the horizontal section can play a certain role in buffering and stabilizing the airflow, and also facilitates the subsequent connection of an oxygen mask or nasal cannula.

[0109] In one embodiment, the bottom wall of the humidification chamber 401 is provided with a support leg, and a support plate is provided on the support leg. The humidification assembly 402 is disposed on the support plate, and the humidification chamber 401 is connected to the humidification assembly 402 at the bottom.

[0110] In one embodiment, such as Figure 6 As shown, it also includes a controller 501, a flow sensor 201 and an oxygen concentration sensor 203 that input data to the controller 501, the controller 501 performs calculations, and the controller 501 outputs data to the display device 204.

[0111] In one embodiment, such as Figure 7As shown, it also includes a controller 501, a flow sensor 201, an oxygen concentration sensor 203, a pressure sensor 205, and a humidity sensor 206 that input data to the controller 501, the controller 501 performs calculations, and the controller 501 outputs data to the display device 204.

[0112] In one embodiment, the regulating valve 202 is electrically controlled and adjusts according to the instructions of the controller 501. When the pressure sensor 205 detects an abnormality in the outlet pressure or the oxygen concentration sensor 203 detects an abnormality in the oxygen concentration, it will quickly feed back to the controller 501. The controller 501 adjusts the regulating valve 202 of the oxygen inlet pipe 101 and the air inlet pipe 102 to mix oxygen and air in a suitable ratio, providing the patient with a stable and high-flow-rate mixed gas that meets the treatment requirements, ensuring the effectiveness and stability of the treatment.

[0113] In one embodiment, the humidification component 402 is electrically controlled and adjusts according to the instructions of the controller 501. When the humidity sensor 206 detects an abnormality in the humidity of the outgoing air, it will quickly feed back to the controller 501. The controller 501 will adjust the humidification component 402 in a timely manner to ensure that the humidity of the gas inhaled by the patient is stable, thereby improving the comfort and safety of oxygen therapy.

[0114] In one embodiment, such as Figure 8 As shown, it also includes a controller 501, a flow sensor 201, an oxygen concentration sensor 203, a pressure sensor 205, a humidity sensor 206, and a temperature sensor 208 that input data to the controller 501, the controller 501 performs calculations, and the controller 501 outputs data to the display device 204.

[0115] In one embodiment, the oxygen concentration sensor 203 is associated with an alarm device 502, which issues an alarm signal when the oxygen concentration sensor 203 detects that the oxygen concentration in the mixed gas is higher than the upper limit or lower than the lower limit.

[0116] In one embodiment, pressure sensor 205, humidity sensor 206, and temperature sensor 208 are associated with alarm device 502.

[0117] In one embodiment, the flow sensor 201, oxygen concentration sensor 203, pressure sensor 205, humidity sensor 206, and temperature sensor 208 each have their own alarm device 502.

[0118] In one embodiment, the controller 501 triggers the alarm device 502 when it detects that each treatment parameter is higher than its respective upper limit or lower than its respective lower limit.

[0119] In one embodiment, in addition to the flow sensor 201 and oxygen concentration sensor 203 as inputs, and the controller 501 as the control and display device 204 as the output, one or more of the following can be added as inputs: pressure sensor 205, humidity sensor 206, temperature sensor 208, input device 503, and one or more of the following can be added as outputs or control targets: regulating valve 202, alarm device 502, humidification assembly 402, and suction drive device 210.

[0120] In one embodiment, when the alarm device 502 is triggered, an alarm light illuminates or an alarm sound is emitted.

[0121] In one embodiment, when the alarm device 502 is triggered, a notification is sent via the display device 204.

[0122] In one embodiment, controller 501 enhances the intake of oxygen and air via inhalation drive device 210.

[0123] In one embodiment, an input device 503 is also included, which is connected to the controller 501 and is used to set the upper and lower limits of each treatment parameter.

[0124] When using this device, regarding the range of treatment parameters, since patients generally experience varying degrees of respiratory failure, the oxygen concentration should initially be set to pure oxygen. The oxygen and air mixing ratio can then be adjusted as needed.

[0125] For adults, a commonly used oxygen flow rate is 30-40 L / min. If there are concerns about patient tolerance, a lower flow rate can be started and gradually increased to a flow rate above 30 L / min. Once the flow rate is fixed, the oxygen concentration should be gradually decreased based on oxygen saturation, maintaining an oxygen saturation between 90-95%. If, at a certain flow rate, pure oxygen still cannot achieve an oxygen saturation above 90%, the flow rate can be increased further until the patient's oxygen saturation improves. Generally, the highest flow rate achievable for high-flow oxygen therapy is 60-70 L / min. The temperature setting is generally close to body temperature (37°C), between 35°C and 39°C.

[0126] Example 1

[0127] In practical use, one end of the oxygen inlet pipe 101 is connected to the mixing input pipe 103 on the side wall of the humidifier 104 via a flange, and the other end is connected to an external oxygen source. Ensure that the air filter 207 is installed at the air inlet end of the air inlet pipe 102 to filter impurities in the air.

[0128] When the oxygen source and the high-flow oxygen detection device are powered on, the device starts to work. The controller 501 automatically adjusts the flow rate of oxygen and air according to the preset treatment parameters. The flow sensor 201 monitors the flow rate of oxygen and air in real time and feeds the data back to the controller 501. The oxygen concentration sensor 203 monitors the oxygen concentration in the mixed gas in real time to ensure stable oxygen quality.

[0129] Humidity sensor 206 and pressure sensor 205 monitor the humidity and pressure of the output gas to ensure that the therapeutic parameters of the gas inhaled by the patient meet the treatment requirements.

[0130] An alarm device 502 is installed near the oxygen concentration sensor 203, pressure sensor 205, and flow sensor 201 and connected to the controller 501. When an abnormality is detected (such as excessively high or low pressure, or excessively high or low oxygen concentration), the controller 501 automatically adjusts the regulating valve 202 and triggers an alarm.

[0131] Connect the outlet tube 105 of the humidifier 104 to the patient's oxygen mask or nasal cannula, and the patient begins to inhale a high-flow-rate mixed gas.
