Description

Technical Field

[0001] The present invention relates to the technical field of respiratory therapy machines, and in particular to a respiratory control structure of a hydrogen-oxygen therapy machine and a control method thereof. Background Art

[0002] The hydrogen-oxygen therapy machine is a medical device that assists in the treatment of a variety of diseases by producing a mixture of hydrogen and oxygen (hereinafter referred to as gas). The hydrogen-oxygen therapy machine uses an electrolyzer to electrolyze water into hydrogen and oxygen, and then mixes the hydrogen and oxygen. The gas is then transported to the patient's respiratory tract (usually using a nasal cannula connected to the patient's nasal cavity) through the gas system for the patient to breathe.

[0003] At present, after the hydrogen oxygen therapy machine is started, the machine will keep working to continuously output gas through the nasal cannula. At the same time, the nasal cannula will output gas no matter when the human body is inhaling or exhaling, which will cause the gas output by the nasal cannula to be wasted when exhaling. The normal inhalation and exhalation time ratio of the human body is 1:2, so the amount of gas wasted when exhaling is much greater than the amount inhaled when inhaling. This is reflected in the electrolytic cell inside the hydrogen oxygen therapy machine. The total amount of hydrogen and oxygen that can be produced by the electrolytic cell of the same specification is often within a certain range. The gas waste caused by exhalation also wastes the mileage of the electrolytic cell, which reduces the effective service life of the hydrogen oxygen therapy machine.

The gas supply mechanism is set to adjust the supply of hydrogen and oxygen gas according to the patient's inhalation frequency and inhalation volume. At the same time, the gas supply mechanism is linked with the supply mechanism to reasonably distribute the gas according to the blockage of the patient's two nostrils to avoid gas waste. Although this patent can adjust the supply of hydrogen and oxygen gas, it still cannot avoid the above-mentioned gas waste problem caused by exhalation. Summary of the invention

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings.

[0039] In the prior art, a pressure sensor is arranged on the nasal suction tube 30, and the pressure sensor is used to judge the breathing state of the nasal cavity according to the air pressure difference generated when the nasal cavity is inhaled and exhaled. Then, an electromagnetic valve designed in the body 10 and matched with the pressure sensor is used to discharge gas during inhalation and stop gas discharge during exhalation, so as to save gas. However, the flow of gas in the pipeline is driven by pressure, and has a delay when it acts on the nasal suction tube 30. This delay phenomenon causes the gas discharge time from the nasal suction tube 30 to be not sensitive enough to the nasal breathing frequency, and in the early stage of the nasal cavity switching from exhalation to inhalation, the gas in the nasal suction tube 30 is still static, and the nasal cavity needs to actively extract the gas, which increases the burden of inhalation and causes discomfort to the patient. Compared with the prior art, this embodiment provides:

[0040] Combination Figure 1-Figure 12 A breathing control structure of a hydrogen oxygen therapy machine includes a machine body 10 and a nasal suction tube 30. The machine body 10 is provided with a gas source system 11 for electrolysis to generate gas, and a gas supply tank 14 for storing the gas. An air circuit tube 20 is connected between the gas supply tank 14 and the nasal suction tube 30. The gas circulates between the gas supply tank 14 and the nasal suction tube 30 through the air circuit tube 20.

[0041] The nasal suction tube 30 includes an air distributor 40 and two nasal suction components 50. The two nasal suction components 50 are respectively inserted into the two nasal cavities. Gas enters from one end of the air distributor 40, is diverted and passes through the two nasal suction components 50 respectively, and then is discharged from the other end. The gas maintains a flow rate through the nasal suction component 50. The nasal suction component 50 is provided with a cut-off mechanism 60 for detecting the breathing state of the nasal cavity. The nasal suction component 50 and the cut-off mechanism 60 cooperate to discharge gas during inhalation and close during exhalation without increasing the burden of nasal inhalation.

[0042] A control system 18 is provided in the machine body 10, and the control system 18 is preferably an MCU control system. The control system 18 controls the coordinated operation of the electrical structure in the machine body 10. The gas source system 11 inside the machine body 10 safely inputs the gas into the gas supply tank 14 through the flame retardant and explosion-proof device 12 (the flame retardant and explosion-proof device 12 is a prior art, and the specific structure is not repeated). A flow valve 13 for detecting the gas flow is arranged between the gas source system 11 and the gas supply tank 14. A pressurized air pump B15 for discharging the gas and an input end for the gas to flow back are provided on one side of the gas supply tank 14. The pressurized air pump B15 is connected to the humidification cup 17 through the gas supply pipe 21, and is connected to the nasal suction tube 30 through the gas circuit pipe 20. After the gas flows through the nasal suction tube 30, it flows back to the input end of the gas supply tank 14 through the gas circuit pipe 20, realizing a circulating flow, so as to achieve the purpose of maintaining the flow rate of the gas in the nasal suction tube 30.

[0043] The gas supply tank 14 includes a first air chamber 141 and a second air chamber 142 which are separated. The first air chamber 141 is connected to the second air chamber 142 through a pressurized air pump A143. A pressure sensor for detecting the indoor pressure is arranged inside the second air chamber 142. The gas generated by electrolysis of the gas source system 11 is first stored in the first air chamber 141 through a flow valve 13. In the process of gas circulation between the second air chamber 142, the airway tube 20 and the nasal suction tube 30, as the patient inhales part of the gas through the nasal suction tube 30, the total amount of gas in the second air chamber 142 is reduced, causing the indoor pressure to decrease. When the pressure sensor detects that the inner pressure decreases, the pressurized air pump A143 can be controlled to compensate the gas in the first air chamber 141 to the second air chamber 142 in an appropriate amount, so as to maintain the indoor pressure of the second air chamber 142 within a constant range. In this way, while satisfying the patient's uniform inhalation of gas, the gas can be fully utilized. Therefore, the gas source system 11 can generate gas by electrolysis at a lower power, thereby extending the service life of the gas source system 11.

[0044] In addition, an exhalation detection device 16 (its structure and function are the same as those of an existing respiratory monitor, and the specific structure will not be repeated here) can be configured on the gas output and input pipelines inside the body 10 and on one side of the gas supply tank 14. The exhalation detection device 16 can determine whether the patient is using the nasal suction tube 30 or leaving the state according to the air pressure fluctuations in the air circuit tube 20 caused by the patient's breathing. When in the leaving state, the pressurized air pump B15 and the air source system 11 can be controlled to stop working and be in a standby state to save electricity. When the patient returns to use it, the gas retained in the second air chamber 142 can be output in time to avoid the patient having to wait. A pressure relief valve connected to the atmosphere is also provided on one side of the second air chamber 142, which is not shown in the figure. When the body 10 is used up and shut down, the pressure relief valve and the pressurized air pump A143 will completely discharge the gas inside the first air chamber 141 and the second air chamber 142 to avoid gas remaining in the gas supply tank 14, which poses a risk of explosion.

[0045] Furthermore, the nasal suction component 50 includes a coaxial outer cylinder 51 and an inner cylinder 53, an annular cavity is formed between the outer cylinder 51 and the inner cylinder 53, the upper side of which is sealed with a rubber film 52, the annular cavity is connected to the inner side of the gas dividing cylinder 40, and a plurality of vents A54 connected to the annular cavity are opened circumferentially on the surface of the inner cylinder 53, and the gas flowing in the gas dividing cylinder 40 will flow through the annular cavity, and can be discharged from the vents A54 and inhaled into the nasal cavity;

[0046] The intercepting mechanism 60 includes an intercepting cover 61 which is rotatably sleeved on the outer surface of the inner cylinder 53. The intercepting cover 61 is made of rigid material and is rotatably assembled on the surface of the inner cylinder 53 through a bearing ring. The intercepting cover 61 is supported by the bearing ring so that the inner surface and the outer surface of the inner cylinder 53 do not contact each other, but the gap is small to reduce the friction between them while having a good sealing effect. A plurality of alignment holes 63 are opened on the surface of the intercepting cover 61 in the circumferential direction. The plurality of alignment holes 63 correspond to the plurality of vents A54 one by one. A fan blade ring 62 is arranged on the lower surface of the intercepting cover 61. The fan blades The ring 62 is driven by the gas with flow rate flowing through the annular cavity from the gas distributor 40. An annular positioning plate 64 is fixedly connected to the upper side of the intercepting cover 61, and a positioning assembly 65 for limiting the rotation of the annular positioning plate 64 is also provided. The positioning assembly 65 is connected to the rubber membrane 52. The gas continuously flowing through the annular cavity from the gas distributor 40 drives the fan blade ring 62 to rotate, so that the intercepting cover 61 rotates on the surface of the rubber membrane 52, or when the annular positioning plate 64 is limited by the positioning assembly 65, the fan blade ring 62 still has rotational potential energy.

[0047] A plurality of positioning grooves A641 and positioning grooves B642 are formed on the surface of the annular positioning plate 64 in a circumferential direction. The rubber membrane 52 triggers the positioning assembly 65 to dock with the positioning groove A641 or the positioning groove B642 according to the air pressure state of the nasal cavity, so as to limit the annular positioning plate 64 to stop the flow intercepting cover 61 from rotating, so that the alignment hole 63 and the vent hole A54 are movably connected or misaligned.

[0048] The positioning assembly 65 includes a pressure sensor and a brake switch. The brake switch is movably connected to the positioning groove A641 and the positioning groove B642. When the positioning groove A641 and the brake switch are connected, the alignment hole 63 and the vent hole A54 are connected. When the positioning groove B642 and the brake switch are connected, the alignment hole 63 and the vent hole A54 are misaligned.

[0049] The brake switch is equivalent to the existing electrically controlled telescopic switch, and the pressure sensor is arranged on one side of the rubber membrane 52. When the nasal cavity changes from inhalation to exhalation, the gas discharged from the nasal cavity and the gas discharged from the annular cavity of the nasal suction component 50 will gather at the position of the rubber membrane 52, and can generate the maximum thrust to squeeze the rubber membrane 52, so that it is quickly detected by the pressure sensor. Then the pressure sensor transmits the electrical signal representing the nasal exhalation to the brake switch. The brake switch first disconnects the lock on the current positioning groove A641, causing the intercepting cover 61 to be in a state where it can rotate, and is driven by the fan blade ring 62 to rotate rapidly. Then the adjacent positioning groove B642 rotates to the bottom of the brake switch with the annular positioning plate 64 and will be locked by the brake switch. At this time, the alignment hole 63 and the vent hole A5 4 is in a misaligned state, at this time, the gas in the annular cavity of the nasal suction component 50 will not be discharged through the vent hole A54, but will all participate in the circulation flow in the gas distributor 40, so no gas will be wasted when the nasal cavity exhales; and when the nasal cavity changes from exhalation to inhalation, the rubber membrane 52 part arches outward due to the negative pressure and is detected again by the pressure sensor, and then the electrical signal representing the nasal inhalation is transmitted to the brake switch, and the brake switch first disconnects the lock of the current positioning groove B642, prompting the adjacent positioning groove A641 to rotate to the bottom of the brake switch and be locked again by the brake switch, at this time, the alignment hole 63 and the vent hole A54 are in a connected state, and at this time, the gas in the annular cavity of the nasal suction component 50 can be discharged through the vent hole A54, so that it can be inhaled by the nasal cavity;

[0050] It is worth mentioning that the rotational kinetic energy of the intercepting cover 61 is generated by the flowing gas driving the fan blade ring 62, so that the rotation of the intercepting cover 61 does not require an external electric drive source, which greatly reduces the volume and weight of the nasal suction tube 30, thereby improving the comfort of the nasal suction tube 30 when wearing.

[0051] Reference Figure 8-Figure 12 In order to make the nasal suction tube 30 not need to be connected to a power source, the positioning component 65 can cooperate with the rubber membrane 52 to complete the braking effect of the annular positioning plate 64, so as to further reduce the configuration volume required for the nasal suction tube 30. This embodiment provides another preferred positioning component 65;

[0052] The positioning assembly 65 includes a mounting seat 651, and a reversing component 655 is rotatably mounted on one side of the mounting seat 651 through a mounting sleeve 6511. The reversing component 655 includes a cooperative rotating shaft 6551 and inclined plane blocks 6552 symmetrically fixedly mounted on both sides. A tilting piece 652 is rotatably mounted on the upper side of the mounting sleeve 6511. The tilting piece 652 cooperates with the rubber membrane 52 to push the reversing component 655 to turn. The reversing component 655 includes a swivel 6522 rotatably mounted on the upper side of the mounting sleeve 6511. The two sides of the rotating ring 6522 are symmetrically fixedly connected with push rods 6523, and the push rods 6523 correspond to the top of the inclined block 6552. One side of the rotating ring 6522 is also fixedly connected with a tilting rod 6521, and one end of the tilting rod 6521 is movably connected to the surface of the rubber membrane 52. When the rubber membrane 52 pushes the surface to be concave toward the inner side of the annular cavity of the nasal suction component 50 due to nasal exhalation, it can push one end of the tilting rod 6521 to cause the rotating ring 6522 to rotate counterclockwise, which enables the push rod 6523 on one side to The inclined surface of the corresponding inclined surface block 6552 is pushed to cause the coordinated rotating shaft 6551 to turn toward one side of the inclined surface block 6552. When the rubber membrane 52 is arched into the nasal cavity due to nasal inhalation, the tilting rod 6521 will pull one end of the tilting rod 6521 to cause the rotating ring 6522 to rotate clockwise, which causes the push rod 6523 on the other side to push the inclined surface of the corresponding inclined surface block 6552, causing the coordinated rotating shaft 6551 to turn toward this side. One end of the reversing component 655 is coaxially fixedly connected There is a limiter 653 that is movably connected to the positioning groove A641 and the positioning groove B642. The limiter 653 includes a fixed sleeve 6531 that is coaxially fixedly connected to the cooperative rotating shaft 6551. A horizontal swing block 6532 is respectively arranged on both sides of the fixed sleeve 6531. A clamping block 6533 is fixedly arranged on the lower surface of the swing block 6532 away from the end of the fixed sleeve 6531. The circumferentially arranged positioning groove A641 and the circumferentially arranged positioning groove B642 are not on the same circumference (such as Fig.10As shown by the dashed line in the middle, the two blocks 6533 on both sides of the fixed sleeve 6531 correspond to the positioning groove A641 and the positioning groove B642 respectively. When the cooperative rotating shaft 6551 is driven by the tilting member 652 to rotate in a skew direction, the block 6533 on one side can be driven to deflect downward so as to engage with the positioning groove A641 or the positioning groove B642. Since the positioning groove A641 and the positioning groove B642 are not on the same circumferential track, they are docked with the corresponding block 6533. When the limiter 653 is engaged, the limiter 653 is provided with a directional component 654 on the upper side thereof to make the limiter 653 maintain elastic inclination to one side. The directional component 654 includes a tension spring 6542. The tension spring 6542 is hoisted above the fixing sleeve 6531 through a support frame 6541 fixed on the upper surface of the assembly sleeve 6511. A movable wheel 6543 is installed on the lower side of the tension spring 6542. A reversing block 6544 is fixed on the upper surface of the fixing sleeve 6531. The reversing block 654 The surface of the 4 is provided with a reversing groove 6545 for assembling the movable wheel 6543. When the fixing sleeve 6531 is deflected to cause the block 6533 on one side to rotate downward, the reversing block 6544 will be driven to deflect, so that the reversing groove 6545 is tilted. Then, the movable wheel 6543 is pulled by the tension spring 6542 to automatically roll to a higher position in the tilted reversing groove 6545, so as to cause the fixing sleeve 6531 to maintain the tilted state, so as to cause the downward block 6533 to be closely attached to the surface of the annular positioning plate 64. When the deflection state of the fixing sleeve 6531 changes, causing the other block 6533 to rotate downward, the reversing block 6544 will also be driven to deflect, so that the other side of the reversing groove 6545 is located at a higher position. The movable wheel 6543 is pulled by the elastic force of the tension spring 6542 to automatically roll to that position, so as to adaptively cause the newly rotated downward block 6533 to be closely attached to the surface of the annular positioning plate 64.

[0053] Specifically, before exhalation from the nasal cavity, the block 6533 on one side of the limiter 653 is clamped in the positioning groove A641, and the alignment hole 63 is connected to the vent hole A54. When exhaling, the air pressure in the nasal cavity will push the surface of the rubber membrane 52 to be concave toward the inner side of the annular cavity of the nasal suction component 50, so that the inner wall of the rubber membrane 52 will push one end of the tilting rod 6521, causing the rotating ring 6522 to rotate counterclockwise, so that the push rod 6523 on one side pushes the corresponding inclined block 6552, causing the coordinated rotating shaft 6551 to move toward the inclined block 6552. 552 is turned on one side, and then the coordinated rotating shaft 6551 is driven to rotate in a biased manner, so that the block 6533 on one side is deflected downward and, under the elastic pulling action of the directional component 654, is pressed against the surface of the annular positioning plate 64, wherein the block 6533 originally at the bottom is disengaged from the engagement with the positioning groove A641, and the annular positioning plate 64 rotates at the same time, and then an adjacent positioning groove B642 rotates to the lower side of the block 6533 at the bottom and engages with it, so that When the annular positioning plate 64 is limited, the alignment hole 63 and the vent A54 are misaligned, and the gas in the annular cavity of the nasal suction component 50 will no longer be discharged through the vent A54. This effect is achieved when the vent A54 is automatically closed during exhalation, thereby saving gas. When the patient changes from exhalation to inhalation, the negative pressure at the rubber membrane 52 will cause the surface of the rubber membrane 52 to arch out toward the inside of the nasal cavity, thereby pulling one end of the tilting rod 6521 to cause the rotating ring 6522 to rotate clockwise, and then through the same method as above, The reverse linkage of the principle causes the block 6533 that was originally engaged with the positioning groove B642 to disengage, and the annular positioning plate 64 rotates at the same time, so that another adjacent positioning groove A641 rotates to the lower side of the new block 6533 at the bottom and engages with it. The annular positioning plate 64 is limited, and the alignment hole 63 and the vent A54 are connected again. When this effect is achieved, the alignment hole 63 and the vent A54 are automatically connected during inhalation, and the gas in the annular cavity of the nasal suction component 50 is discharged, so that the nasal cavity can be inhaled.

[0054] Combination Figure 8 In the previous embodiment, the inner cylinder 53 includes a funnel cylinder 532 and an air outlet cylinder A531 which are arranged at the top and the bottom. The funnel cylinder 532 and the air outlet cylinder A531 are coaxially designed as a whole. The vent hole A54 is provided on the surface of the funnel cylinder 532. The air outlet cylinder A531 penetrates the inner side of the air separator cylinder 40 and is connected to the lower surface of the air separator cylinder 40. The design of the air outlet cylinder A531 being connected to the lower surface of the air separator cylinder 40 allows the patient to exhale the air through the air outlet cylinder A531. The design of the small opening on the lower side of the air outlet cylinder A531 allows the patient to breathe, causing a larger range of changes in the air pressure difference at the rubber membrane 52, thereby increasing the corresponding deformation of the rubber membrane 52 with the air pressure, so that the positioning component 65 can accurately detect it.

[0055] Combination Figure 5-Figure 6In the previous embodiment, the surface of the gas dividing cylinder 40 is provided with a mounting plate 43 for assembling two outer cylinders 51, and two circular grooves 44 are provided on the surface of the mounting plate 43. A partition 41 is provided on the inner side of the gas dividing cylinder 40. The partition 41 evenly separates the inner cavity of the gas dividing cylinder 40 and the circular groove 44. An arc-shaped baffle 45 is sealed on the inner side of the circular groove 44. The arc-shaped baffles 45 in the two circular grooves 44 are respectively arranged on both sides of the partition 41. After the space in the gas dividing cylinder 40 is divided by the partition 41, the space on one side is only connected to one circular groove 44. The partition 41 is A guide plug 42 for guiding the gas is also provided on the side of the guide plug 42, and a partition plate 421 extending to the inner side of the outer cylinder 51 is integrally provided on the upper side of the guide plug 42; through the isolation of the partition plate 41 and the guidance of the guide plug 42 and the partition plate 421, the gas flowing on both sides of the partition plate 41 is passed into the annular cavity inside the outer cylinder 51 in equal amounts and at equal flow rates. Under the isolation effect of the partition plate 421, the gas flowing into the annular cavity will flow around the inner side for a circle, and then flow back to the gas distribution cylinder 40 along the other side of the partition plate 421 and the guide plug 42 (such as Figure 5 Indicated by the dotted arrow in the middle), so that the gas can keep flowing in the gas distribution cylinder 40 and the outer cylinder 51;

[0056] The outer periphery of the blade ring 62 is also covered with a blocking cover 621, which is fixedly arranged on the upper surface of the arc-shaped baffle plate 45. The blocking cover 621 covers the blade ring 62, and only allows the gas in the gas distributor 40 to contact the blade ring 62 when it flows into the inner side of the outer cylinder 51 through the circular groove 44. In this way, when the gas in the gas distributor 40 flows into the inner side of the outer cylinder 51, it will drive the blade ring 62 to rotate, thereby providing power for the intercepting cover 61 to rotate on the outer surface of the inner cylinder 53. The purpose of setting the blocking cover 621 is to prevent the gas in the outer cylinder 51 from flowing back to the gas distributor 40 on the other side of the isolation plate 421, causing a reaction force on the blade ring 62, thereby inhibiting the rotation of the blade ring 62.

[0057] Combination Figure 3 In the previous embodiment, the air circuit tube 20 includes a circulation tube 23 connected between the body 10 and the nasal suction tube 30. The inner side of the circulation tube 23 is divided into two circulation chambers 231. Two docking tubes 24 are provided at the ends of the circulation chambers 231. The two docking tubes 24 are respectively connected to the two circulation chambers 231 inside the circulation tube 23. The two docking tubes 24 at one end of the circulation tube 23 are respectively connected to the two sides of the gas distribution cylinder 40. The two docking tubes 24 at the other end of the gas distribution cylinder 40 are respectively connected to the input end and the output end of the gas supply tank 14.

[0058] Specifically, one docking tube 24 is connected to the air outlet of the humidification cup 17, and the other docking tube 24 is correspondingly connected to the return air pipe 22 connected to the air inlet end of the second air chamber 142. The second air chamber 142 discharges gas into the humidification cup 17 through the air supply pipe 21. After the gas is moistened, it is input into the corresponding connected circulation cavity 231 through the docking tube 24 connected on one side, and then flows into the inner side of the nasal suction tube 30, and then is discharged from the other side of the nasal suction tube 30, flows into another circulation cavity 231, and finally flows back to the second air chamber 142 through the return air pipe 22.

[0060] S1: Wear the nasal suction tube 30 to the nose, and insert the two nasal suction components 50 into the two nasal cavities respectively;

[0061] S2: Start the machine body 10 to allow gas to flow into the nasal suction tube 30 and maintain the flow rate continuously;

[0062] S3: Setting the flow rate of the gas in the nasal suction tube 30 through the machine body 10, and correspondingly adjusting the amount of gas discharged through the vent A54, so as to achieve the patient's adjustment of the amount of gas inhaled;

[0063] S4: As the patient's breathing causes the rubber membrane 52 to change, the positioning component 65 automatically connects or displaces the vent hole A54 and the alignment hole 63 according to the change of the rubber membrane 52, so as to adapt to the patient's exhalation frequency without increasing the patient's inhalation burden;

[0064] S5: After use, the machine body 10 will automatically discharge the gas temporarily stored inside, thereby improving the safety of use of the machine body 10.
