Description

Technical Field

[0001] This invention relates to the field of oxygen supply, and more specifically, to a timely response, inhalation-type oxygen generator and method. Background Technology

[0002] Generally speaking, men have a slightly higher respiratory rate than women. As age increases, the respiratory rate usually decreases. The respiratory rate of infants is usually 40-60 breaths per minute, while that of the elderly is usually 12-20 breaths per minute. The inhalation time is usually between 1-2 seconds, and the exhalation time is usually between 2-3 seconds. The average respiratory volume of an adult is 500-600 ml.

[0003] During respiration, the volume of the non-gas exchange portion of the human respiratory tract is about 150 ml. This volume is also known as the physiological dead space. When a person inhales, the first thing to enter the alveoli of the lungs is the waste gas that remained in the respiratory tract during the previous exhalation. Of the approximately 500 ml of air inhaled each time, only about 350 ml enters the lungs, and about 150 ml remains in the respiratory tract. In other words, when exhaling, the first thing to be expelled is the approximately 150 ml of oxygen that remained in the respiratory tract, and only then is the waste gas expelled.

[0004] Treating this oxygen directly as waste gas would be extremely wasteful. Furthermore, the intermittent oxygen supply method, which waits for the pressure inside the breathing mask to drop before supplying oxygen, will create a lag, and this lag will be more pronounced the faster the breathing rate. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a timely response oxygen generator and method that provides oxygen inhalation, which solves the problems of how to improve oxygen utilization and how to provide timely oxygen inhalation without lag.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] On the one hand, this application provides a timely response, inhalation-type oxygen generator, including an air compressor, a main filter, a dryer, a first filter, an air storage tank, a molecular sieve oxygen generator, an oxygen concentration detector, an oxygen storage tank, a second filter, an oxygen concentration display, a flow meter, a manifold, and an oxygen supply network, all connected in sequence via pipelines. It also includes a breathing mask, an inhalation tube, an exhalation tube, an oxygen supply network, a circulation pipeline, and a controller. The breathing mask is connected to the outside world via the exhalation tube, and the controller is also connected to the exhalation tube. The controller is connected to the breathing mask via the circulation pipeline, and the breathing mask is connected to the oxygen supply network via the inhalation tube.

[0008] Based on further optimization of the above scheme,

[0009] Furthermore, the controller includes a first interface, a second interface, and a third interface, the extensions of the first interface, the second interface, and the third interface are connected to the spherical cavity, and a three-way ball valve is provided in the spherical cavity, the three-way ball valve being fixedly connected to the motor shaft.

[0010] Furthermore, one of the vent ports of the three-way ball valve is equipped with an exhaust fan.

[0011] Furthermore, the dimensions of the three-way ball valve, including the vent for the exhaust fan, the adjacent vent, and the vent opposite to the exhaust fan, decrease sequentially.

[0012] Furthermore, a curtain is also provided at the interface between the circulation pipe and the breathing mask.

[0013] Furthermore, the door curtain consists of a semi-circular upper door curtain and a semi-circular lower door curtain. The arc-shaped edges of the upper and lower door curtains are fixedly connected to the wall of the circulation pipe, and the straight edges of the upper and lower door curtains are in contact with each other.

[0014] On the other hand, this application provides an oxygen supply method based on the aforementioned timely response inhalation-type oxygen generator, comprising the following steps.

[0015] S1. Using a breathing mask, inhale. The pressure sensor inside the breathing mask senses the decrease in pressure inside the mask, and the electronic valve on the inhalation tube opens, allowing the user to inhale through the inhalation tube.

[0016] S2. After inhaling, exhale. The exhaled air enters the breathing mask. The pressure sensor inside the breathing mask senses the increase in pressure inside the mask and sends the initial exhaled oxygen flow in the respiratory tract into the circulation tube. Then, the exhaust gas at the end is sent into the exhalation tube.

[0017] S3. After exhalation weakens, the pressure sensor senses the decrease in pressure inside the breathing mask, and while expelling the remaining waste gas, it drives the gas in the circulation pipe to be sent into the breathing mask.

[0018] S4. After exhaling, inhale; repeat steps S1-S3.

[0019] In summary, the present invention has the following beneficial effects:

[0020] By setting up a circulation pipeline, not only is the oxygen utilization rate improved, but the response speed of the oxygen generator is also increased, and the lag in oxygen supply during inhalation is reduced. Attached Figure Description

Detailed Implementation

[0028] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] On one hand, this application provides a timely response, inhalation-type oxygen generator, including an air compressor 1, a main filter 2, a dryer 3, a first filter 4, an air storage tank 5, a molecular sieve oxygen generator 6, an oxygen concentration detector 7, an oxygen storage tank 8, a second filter 9, an oxygen concentration display 10, a flow meter 11, a manifold 13, and an oxygen supply network 12, a breathing mask 15, an inhalation tube 20, an exhalation tube 17, an oxygen supply network 12, a circulation pipeline 16, and a controller 18, all connected sequentially via pipelines. The breathing mask 15 is connected to the oxygen supply network 12 via the exhalation tube 17. The external connection is provided, and the exhalation tube 17 is also connected to a controller 18. The controller 18 includes a first interface, a second interface and a third interface. The extensions of the first interface, the second interface and the third interface are connected to the spherical cavity. A three-way ball valve 22 is provided in the spherical cavity. The three-way ball valve 22 is fixedly connected to the rotating shaft of the motor. An exhaust fan 2201 is installed in one of the air ports of the three-way ball valve 22. The size of the air port of the three-way ball valve 22 with the exhaust fan 2201, the adjacent air ports and the air ports opposite to the exhaust fan 2201 decrease in size in sequence.

[0030] The controller 18 is connected to the breathing mask 15 through the circulation pipe. A curtain is also provided at the interface between the circulation pipe 16 and the breathing mask 15. The curtain consists of a semi-circular upper curtain 1601 and a semi-circular lower curtain 202. The arc-shaped edges of the upper curtain 1601 and the lower curtain 202 are fixedly connected to the pipe wall of the circulation pipe 16. The straight edges of the upper curtain 1601 and the lower curtain 202 are in contact with each other. The breathing mask 15 is connected to the oxygen supply network 12 through the inhalation pipe 20. An electric control valve 19 and a pressure reducing valve 21 are also installed between the inhalation pipe 20 and the oxygen supply network 12.

[0031] The oxygen supply method of this application includes the following steps:

[0032] Specifically, this application includes the following steps in the oxygen supply process:

[0033] S1. Using the breathing mask 15, inhale. The pressure sensor inside the breathing mask 15 senses that the pressure inside the breathing mask 15 has decreased, and the electric valve 19 on the inhalation tube 20 opens. The user inhales through the inhalation tube 20. At this time, the electric valve 19 on the exhalation tube 17 is closed. The oxygen in the oxygen supply network 12 enters the breathing mask 15 through the inhalation tube 20, and the user can inhale the oxygen in the breathing mask 15.

[0034] S2. After inhalation, exhale. The exhaled air enters the breathing mask 15. The pressure sensor inside the breathing mask 15 senses the increased pressure inside the mask 15 and sends the initial exhaled oxygen flow in the respiratory tract into the circulation tube 16. Then, the exhaust gas is sent into the exhalation tube 17. Specifically, the solenoid valve 19 on the inhalation tube 20 is closed, and the solenoid valve 19 on the exhalation tube 17 is opened. At the same time, the three-way ball valve 22 is driven to rotate to the desired position. Figure 3 As shown, residual oxygen in the respiratory tract is first expelled during exhalation. The expelled oxygen passes through the circulation pipe 16, then through the three-way ball valve 22, and finally enters the lower part of the exhalation tube 17. Different time intervals are set for different groups. Since the power of the exhaust fan 2201 is constant, the pressure at the circulation pipe 16 is constant, so the flow rate entering the circulation pipe 16 can be roughly estimated. By controlling the time, the oxygen entering the circulation pipe 16 is controlled. When the oxygen in the respiratory tract is about to be exhausted, the three-way ball valve 22 is driven to rotate to the position shown. Figure 4 At this position, the front and rear parts of the exhalation tube 17 are connected, and the rotation of the exhaust fan 2201 will directly draw the exhaust gas in the breathing mask 15 and discharge it to the outside through the exhalation tube 17.

[0035] S3. After exhalation weakens, the pressure sensor detects a decrease in pressure inside the breathing mask 15. Simultaneously, it expels the remaining waste gas and drives the gas in the circulation pipe 16 to be delivered into the breathing mask 15. Specifically, when the pressure sensor detects a decrease in pressure, but the pressure is still greater than the pressure during inhalation, it can be considered that the user is about to complete the exhalation and enter the inhalation phase. At this time, the three-way ball valve 22 is driven to rotate to... Figure 5 At the position shown, the exhaust fan 2201 draws in the exhaust gas from the breathing mask 15. Since the end of the three-way ball valve 22 with the exhaust fan has the largest opening and the air vent directly opposite the exhaust fan has the smallest opening, exhaust will be performed at the same time, and oxygen in the circulation pipe 16 will be pushed into the breathing mask 15.

[0036] S4. After exhalation, inhale. At this time, through circulation, the waste gas in the breathing mask 15 enters the exhalation tube 17, while the oxygen in the circulation tube 16 enters the breathing mask 15, which plays a compensating role. After the pressure in the breathing mask 15 decreases, the inhalation tube 20 supplies oxygen into the breathing mask 15. By setting up the circulation tube 16, not only is the oxygen utilization rate improved, but the response speed of the oxygen generator is also improved, and the lag in oxygen supply during inhalation is reduced. Repeat steps S1-S3.
