[0002] In the fields of medical treatment and first aid, oxygen supply is one of the important measures to maintain the life of patients. Traditional oxygen supply methods usually rely on high-pressure oxygen cylinders. Although these oxygen cylinders can provide sufficient oxygen, they have the disadvantages of large volume, heavy weight, and are particularly inconvenient to carry in high-altitude environments. Although portable carbon fiber cylinders made of lightweight materials can partially alleviate the weight problem, their effective oxygen supply time can only last for 1-2 hours, and still cannot meet the all-weather continuous oxygen demand for high-altitude tourism, field rescue, etc. In addition, traditional oxygen supply methods often cannot accurately adjust the oxygen flow according to the actual breathing needs of patients, resulting in problems of oxygen waste or insufficient supply. Therefore, traditional mechanical oxygen regulators came into being. Although they can achieve the adjustment of oxygen flow to a certain extent, the adjustment accuracy and response speed are limited, and they cannot meet the high-precision and real-time requirements for oxygen supply in modern medical treatment and first aid fields.

Detailed implementation manners

[0024] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the following further elaborates in detail on a portable intelligent oxygen supply device proposed by the present invention in combination with the accompanying drawings and specific implementation manners. According to the following description, the advantages and features of the present invention will be clearer. It should be noted that the accompanying drawings are in a very simplified form and all use non-precise scales, only for the purpose of conveniently and clearly assisting in explaining the implementation manners of the present invention. In order to make the objectives, features and advantages of the present invention more obvious and understandable, please refer to the accompanying drawings. It should be noted that the structures, scales, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention. Therefore, they do not have technical essential meanings. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects that the present invention can produce and the objectives that can be achieved, should still fall within the scope covered by the technical content disclosed by the present invention.

[0025] Please refer to Figures 1 to 8, the portable intelligent oxygen supply device of this embodiment, the device includes a housing 1 formed by connecting a first valve body 11, a second valve body 12, a first outer shell 13 and a second outer shell 14. Preferably, the first valve body 11 and the second valve body 12 are detachably connected by bolts, and the first outer shell 13 is connected to the first valve body 11 as an upper shell, and the second outer shell 14 is connected to the first valve body 11 and the second valve body 12 as a main shell. A through port 121 is provided in the second valve body 12. The device further includes an adjustment assembly 2, and the adjustment assembly 2 is adjustably fitted to the second valve body 12 to act on the through port 121, thereby realizing the control of the air outlet of the device. The second valve body 12 is further provided with a first interface 123, a second interface 124, a third interface 125 and a fourth interface 126 that are all communicated with the through port 121. Preferably, the first interface 123 is used as an inflation port, the second interface 124 is used for air pressure detection to detect the air pressure at the through port 121, the third interface 125 is used as a safety valve installation location, and air is released when the device air pressure is too high to ensure safety. The fourth interface 126 is used to connect to an oxygen cylinder for air supply. The above first interface 123 can inflate the oxygen cylinder through the through port 121 and the fourth interface 126 in sequence.

[0026] Furthermore, since the fourth interface 126 of the oxygen supply device in this embodiment is configured to connect to a high-pressure oxygen cylinder, the sealing requirement for the device is high. Consequently, the adjustment of the gas at the through port 121 by the adjustment assembly 2 needs to be convenient and have reliable sealing. Specifically, the adjustment assembly 2 includes a push rod 21, a first socket part 22, and a second socket part 23. The first socket part 22 is respectively fitted to the second socket part 23 and the second valve body 12. Specifically, the outer circle and the left end face of the first socket part 22 are fitted to the second valve body 12, and the inner hole and the right end face of the first socket part 22 are processed and then fitted to the outer circle and the left end face of the second socket part 23 after processing. The second socket part 23 is also respectively fitted to the second valve body 12 and the push rod 21. A first sealing ring 24 is evenly arranged between the push rod 21 and the second socket part 23 near the through port 121. Through the arrangement of the first sealing ring 24, the airtightness is improved. Preferably, the first socket part 22 is made of polyurethane resin material and is formed by injecting glue and curing in the second valve body 12, which can deform to a certain extent when stressed and achieve a good elastic sealing effect. The second socket part 23, as a sealing flange for pressing the first socket part 22, can be independently and finely processed to improve the fitting accuracy with the first socket part 22 and the second valve body 12. The adjustment assembly 2 further includes a third socket part 25 and a first knob 26. A thread 211 is provided at one end of the push rod 21 away from the through port 121. One end of the third socket part 25 abuts against the second socket part 23, and a part of the third socket part 25 is also fitted to the thread 211, and the thread 211 is fitted to the first knob 26. The second valve body 12 is also provided with a third air passage 122. Preferably, the third socket part 25 is a threaded seat that is pressed against the second valve body 12 by threaded connection to achieve the effect of pressing the second socket part 23 and the push rod 21. The third socket part 25 presses the second socket part 23, and the second socket part 23 acts on the first socket part 22, causing the first socket part 22 to be axially compressed and radially deformed and expanded, thereby improving the sealing performance with the second valve body 12. The first knob 26 is an oxygen outlet switch adjustment handwheel for controlling the gas to enter the third air passage 122 at the through port 121. The adjustment assembly 2 further includes a sealing part 27. The sealing part 27 is arranged at the through port 121 and on the side of the through port 121 close to the push rod 21. The through port 121 penetrates through the sealing part 27. Preferably, the sealing part 27 is also made of polyurethane resin material and is formed by injecting glue and curing, and deforms when contacting the push rod 21 to achieve good sealing performance.

[0027] Specifically, by adjusting the first knob 26, the push rod 21 is moved, that is, the push rod 21 is moved closer to or away from the through port 121. When the push rod 21 moves closer to the through port 121, after the push rod 21 moves and abuts against the sealing portion 27, the through port 121 is not in communication with the third air passage 122, and air outlet cannot be performed in this case. Correspondingly, when the push rod 21 moves away from the through port 121, at this time the push rod 21 is separated from the sealing portion 27, and in this case the through port 121 is in communication with the third air passage 122.

[0028] Further, a pressure reducing assembly 4 is further disposed inside between the first valve body 11 and the second valve body 12. The pressure reducing assembly 4 includes a first pressure reducing member 41, a second pressure reducing member 42, and a first elastic member 43. One end of the first elastic member 43 is fitted to the first pressure reducing member 41, and the other end of the first elastic member 43 is fitted to the second pressure reducing member 42. Preferably, the first pressure reducing member 41 is a pressure reducing piston, and the second pressure reducing member 42 is a pressure reducing piston sealing base. A balance air chamber is formed between the first pressure reducing member 41 and the second pressure reducing member 42, and the above-mentioned first elastic member 43 is located in the balance air chamber. The first pressure reducing member 41 is movably fitted to the second pressure reducing member 42, and at the fitting portion of the first pressure reducing member 41 and the second pressure reducing member 42, a second sealing ring 44 is provided on the surface of the first pressure reducing member 41 to improve the airtightness when the first pressure reducing member 41 moves relative to the second pressure reducing member 42 and prevent air leakage. A third sealing ring 45 is further provided at one end of the second pressure reducing member 42 close to the third air passage 122 to ensure the airtightness of gas flow. The first pressure reducing member 41 is also partially fitted to the first valve body 11 to control the stroke of the first pressure reducing member 41 moving relative to the second pressure reducing member 42. Preferably, local seals are used between the first pressure reducing member 41 and the first valve body 11 and between the second pressure reducing member 42 and the second valve body 12, effectively improving the sealing performance of gas transmission.

[0029] Further, a second air passage 411 is opened in the first pressure reducing member 41, and the third air passage 122 and the second air passage 411 can be in communication or closed. Specifically, since the piston area of the space into which the gas enters after coming out of the second air passage 411 is much larger than the hole area of the third air passage 122, using Pascal's principle, the first pressure reducing member 41 moves relative to the second pressure reducing member 42 under the action of the first elastic member 43 to control the communication or closing between the second air passage 411 and the third air passage 122.

[0030] Further, the device further includes a control component 5 cooperating with the first valve body 11. The control component 5 includes an adjusting member 51 which cooperates with the first pressure reducing member 41 and is also rotatably cooperated with the first valve body 11. At least one fourth air passage 511 is provided at one end of the adjusting member 51 close to the first pressure reducing member 41. A first air passage 111 is further provided in the first valve body 11. The control component 5 further includes a solenoid valve 52 and a second knob 53. The solenoid valve 52 cooperates with the first air passage 111. Specifically, during pulsed oxygen delivery, when the solenoid valve 52 is de-energized, the gas does not flow from the fourth air passage 511 into the first air passage 111 and is blocked by the solenoid valve 52. When the solenoid valve 52 is energized, the gas flows from the fourth air passage 511 into the first air passage 111. The second knob 53 is connected to one end of the adjusting member 51 away from the first pressure reducing member 41. Preferably, the second knob 53 is a handwheel for adjusting pulsed and continuous oxygen delivery. By rotating the adjusting member 51 through the second knob 53 and combining with the solenoid valve 52, the fourth air passage 511 can be made communicable or closed relative to the first air passage 111. The control component 5 further includes a second elastic member 54. A recessed portion 512 is provided at one end of the adjusting member 51 close to the pressure reducing component 4. One end of the second elastic member 54 cooperates with the recessed portion 512 and the other end cooperates with the first pressure reducing member 41. Through the arrangement of the second elastic member 54, while being able to apply a pre-tightening effect to the first pressure reducing member 41 and the adjusting member 51, it can buffer the movement of the first pressure reducing member 41 and protect the operation of the device.

[0031] Further, the device further includes an air outlet assembly 3 disposed in the first valve body 11. Preferably, the air outlet assembly 3 is arranged not to exceed the end face of the first valve body 11 to prevent damage to the air outlet assembly 3 when the device falls. The air outlet assembly 3 includes an oxygen outlet nozzle 31 and a filter element 32. The two sides of the filter element 32 are respectively fitted to the oxygen outlet nozzle 31 and the first air passage 111, and the gas coming out of the first air passage 111 is filtered through the filter element 32. A monitoring port 311 is further opened on the surface of the oxygen outlet nozzle 31. A monitoring member 7 is further disposed in the housing 1, and the monitoring member 7 is fitted to the monitoring port 311. The monitoring member 7 directly collects the breathing state of the user's nasal end communicated with the oxygen outlet nozzle 31 through the monitoring port 311. Compared with the traditional sampling detection before filtration, it can reduce the time from the emission to the stabilization of the pulsed air flow during oxygen supply. At the same time, the weak air flow changes during the user's breathing can be more accurately collected without being blocked by the filter element 32, providing a synchronous breathing mode of human-machine integration for the device. The oxygen dose can be automatically and intelligently adjusted according to the user's breathing activity level, increasing the dose during activity, reducing the dose during rest and maintaining a constant output flow to meet the needs. The air outlet assembly 3 further includes a pressing member 33, and the pressing member 33 is fitted to the first valve body 11 as a pressing flange to press the oxygen outlet nozzle 31.

[0032] Further, the device is further provided with a circuit board 6 and a battery 8. The circuit board 6, the monitoring member 7 and the battery 8 are all located in the space enclosed by the first valve body 11, the first housing 13 and the second housing 14. An operation panel 9 is further provided on the surface of the first housing 13. The operation panel 9 includes a power quantity display member 91, a power switch member 92, a pulse gear member 93 and a pulse switching member 94. The power quantity display member 91 is used to display the real-time power quantity of the battery 8. Preferably, in order to reduce the power consumption of the battery 8, the power quantity display only flashes at a fixed frequency when the power quantity of the battery 8 is low. The power switch member 92 is used to control the use of the device under pulsed oxygen supply. Under continuous oxygen supply, the battery 8 is not required to provide power. The pulse gear member 93 and the pulse switching member 94 interact to realize the pulse adjustment of the device, and can release a short pulse of oxygen during inhalation to meet the user's oxygen inhalation needs. It can also set different gears according to the device settings and the user's oxygen inhalation needs to change the time and flow rate of pulsed oxygen supply.

[0033] The circuit board 6 is electrically fitted to the monitoring member 7, the battery 8, the solenoid valve 52 and the operation panel 9 respectively to realize the intelligent control of the device in this embodiment. Preferably, in this embodiment, two batteries 8 are provided on both sides of the control assembly 5, which not only improves the power supply endurance of the device, but also makes full use of the space of the first valve body 11, with a compact layout and improved portability.

[0034] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as falling within the scope described in this specification.

[0035] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
