Description

Technical Field

[0001] The present invention relates to the technical field of hyperbaric oxygen therapy, and in particular to a medical air pressurized oxygen chamber respirator device. Background Art

[0002] The principle of a medical air recompression chamber is to pressurize a sealed chamber to a certain atmospheric pressure. Patients in this above-atmospheric pressure environment inhale pure oxygen, thereby achieving the goal of treating their illness. Its unique efficacy in treating conditions such as hypoxic encephalopathy has led to an increasing number of major hospitals adding medical air recompression chambers. To ensure treatment safety, the oxygen concentration in the chamber must be controlled below 23.5%. Therefore, patients wear masks and breathe pure oxygen through a respirator.

[0003] In the prior art, patent document CN217772718U discloses a medical air pressurized oxygen chamber low-resistance oxygen inhalation device, comprising an oxygen inhalation assembly for providing oxygen to a patient, the oxygen inhalation assembly comprising a regulating valve, an oxygen buffer tank, a respirator, and a breathing mask. The regulating valve is connected to the oxygen buffer tank, the respirator is connected to the oxygen buffer tank, an oxygen supply bellows is provided on the respirator, and an oxygen inhalation and exhaust three-way valve is provided on the breathing mask. The two ends of the three-way valve are respectively connected to the oxygen supply bellows and the breathing mask, and the third end of the three-way valve is connected to the oxygen exhaust pipeline. The end of the regulating valve away from the oxygen buffer tank is connected to a pressure-stabilized oxygen supply device. This application has the effect of being able to inject oxygen into the oxygen buffer tank through the pressure-stabilized oxygen supply device, so that the oxygen in the oxygen buffer tank is always in a saturated state, thereby improving the oxygen inhalation resistance that occurs after patients use the oxygen inhalation device for a long time, making oxygen inhalation difficult for patients.

[0004] The ventilator only provides oxygen during the oxygen inhalation process. If the patient does not inhale, no oxygen will be provided. Since the ventilator has a certain resistance when supplying oxygen, it is difficult for some comatose patients to inhale oxygen, which greatly reduces the treatment effect. Based on this, the existing medical air pressurized oxygen chamber ventilator has the problem of difficult to adjust the oxygen inhalation resistance, which cannot meet the needs of different patients and needs to be solved urgently. Therefore, the present application provides a medical air pressurized oxygen chamber ventilator device to meet the needs. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a medical air pressurized oxygen chamber respirator device to solve the problem that the oxygen absorption resistance of the existing medical air pressurized oxygen chamber respirator is difficult to adjust.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: A medical air pressurized oxygen chamber respirator device comprises a respirator body, an oxygen inlet connector and an oxygen inhalation connector fixedly mounted on both sides of the respirator body, a buffer tank fixedly mounted inside the respirator body, an expandable or contractible compensator fixedly mounted on the surface of the buffer tank, an inner cavity of the compensator communicating with the inner cavity of the buffer tank, a mounting sleeve fixedly mounted inside the respirator body, and the compensator movably disposed within the mounting sleeve; A balancing assembly is provided on the top of the mounting sleeve, which provides the compensator with a force to overcome the compensator's own deformation resistance; a regulating valve is fixedly installed inside the respirator body, and the oxygen inlet connector, buffer tank, regulating valve and oxygen inhalation connector are connected in series in sequence. An adjusting mechanism is provided inside the regulating valve, which controls the magnitude of the force exerted by the balancing assembly on the compensator. During the oxygen inhalation process, the buffer tank outputs oxygen, and there is no oxygen when no oxygen is inhaled. This force overcomes the compensator's own deformation resistance and reduces the resistance to oxygen inhalation from the buffer tank.

[0007] Optionally, the balancing assembly includes a counterweight plate and an electromagnetic sleeve, a magnetic column is fixedly mounted on the upper surface of the counterweight plate, the counterweight plate is fixedly mounted on the upper end of the compensator, the electromagnetic sleeve is fixedly mounted on the upper end of the mounting sleeve, and the magnetic column is slidably inserted in the electromagnetic sleeve.

[0008] Optionally, a first excitation coil and a second excitation coil are embedded in the interior of the electromagnetic sleeve. When the first excitation coil and the second excitation coil are energized, they both generate a magnetic attraction force on the magnetic column in the opposite direction to the gravity of the counterweight plate. By simply changing the current introduced into the electromagnetic sleeve, the force exerted by the balancing component on the compensator can be changed, making the adjustment of the oxygen absorption resistance more convenient.

[0009] Optionally, an air pressure chamber is opened inside the regulating valve, an air pressure ring is embedded in the inner wall of the air pressure chamber, the air pressure chamber is connected with the inner cavity of the buffer tank through the inner hole of the air intake ring, the oxygen intake joint is connected with the air pressure chamber, and a one-way diaphragm is fixedly installed on the surface of the air intake ring, and the one-way diaphragm covers the inner hole of the air intake ring.

[0010] Optionally, the regulating mechanism includes a first elastic electrode, a second elastic electrode and a diaphragm, a balancing chamber connected to the outside atmosphere is opened inside the regulating valve, a connecting window is provided between the balancing chamber and the air pressure chamber, the diaphragm is fixedly installed in the connecting window, and the balancing chamber and the air pressure chamber are separated by the diaphragm, the first elastic electrode and the second elastic electrode are both installed in the balancing chamber, and the second elastic electrode is fixedly installed on the surface of the diaphragm, when the first elastic electrode and the second elastic electrode are electrically connected, the power supply circuit of the second excitation coil is connected, and during the oxygen inhalation process, the counterweight plate slides up and down, compressing the compensator, so that the cache tank has the function of active exhaust, this design enables the respirator to have the oxygen exhaust function synchronized with the user's breathing rhythm, which not only greatly reduces the oxygen inhalation resistance, but also provides convenience for oxygen inhalation treatment of patients with weak breathing.

[0011] Optionally, the adjustment mechanism also includes a rotating disk rotatably installed in the balancing chamber, and a servo motor for driving the rotating disk to rotate is fixedly installed on the upper surface of the regulating valve. A plurality of groups of conductive components are embedded in the interior of the rotating disk, and the plurality of groups of conductive components are arranged in a ring array. Each group of conductive components includes an upper electrode sheet, a resistor element and a lower electrode sheet that are connected in series. The upper electrode sheet and the lower electrode sheet are respectively embedded in the upper and lower surfaces of the rotating disk. The first elastic electrode and the second elastic electrode are in sliding contact with the upper and lower surfaces of the rotating disk respectively. When the rotating disk rotates, the first elastic electrode can contact the upper electrode sheet, and the second elastic electrode can contact the lower electrode sheet. During the rotation of the rotating disk, the first elastic electrode and the second elastic electrode are intermittently connected through the conductive components, and the counterweight disk moves up and down to realize the function of active oxygen discharge. When in use, the speed of the rotating disk is set, and oxygen can be discharged at the required frequency to meet the use needs of comatose patients.

[0012] Optionally, the resistance values ​​of the resistance elements of the multiple groups of conductive components increase in sequence, and the pressure of the counterweight plate on the compensator is Fp. Due to the compression process of the compensator, the compressive resistance Fk of the compensator to the counterweight plate gradually increases. The resistance values ​​of each resistance element 23 are reasonably selected to ensure that the increments of Fp and Fk are consistent. When the compensator is compressed to different degrees, the counterweight plate can reach a suspended equilibrium state again, which solves the problem of large changes in the deformation resistance of the compensator itself and affecting the oxygen inhalation resistance, making the patient's oxygen inhalation smoother and meeting the use needs of oxygen inhalation treatment for different patients.

[0013] Optionally, a vertical slide groove is provided on the inner wall of the mounting sleeve, and a sensing block is fixedly installed on the surface of the counterweight plate. The sensing block slides along the vertical slide groove, and a number of slot-type optical couplers are embedded in the vertical slide groove. When the sensing block blocks the sensing end of the slot-type optical coupler, the slot-type optical coupler is triggered to send a signal.

[0014] Optionally, a solenoid valve is fixedly installed at the input end of the oxygen inlet connector, and the opening and closing of the solenoid valve is controlled by signals from two slot-type optocouplers located at the upper and lower ends to meet the demand for injecting oxygen into the buffer tank. At the same time, the position signal of the counterweight plate is obtained through the slot-type optocoupler to control the lighting of each LED light on the matrix LED light board. In this way, whether the compensator is moving and the amplitude of the movement can be monitored in real time, as well as whether the patient is inhaling oxygen and the approximate amount of oxygen inhaled.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, a compensator is set on the buffer tank, and the balance component provides the compensator with a force to overcome the compensator's own deformation resistance. When oxygen is injected into the buffer tank, the compensator expands to reduce the internal air pressure. When the patient inhales oxygen, the compensator contracts to reduce the oxygen inhalation resistance, ensuring that the air pressure in the buffer tank is close to the external atmospheric pressure. The patient always inhales the oxygen buffered in the buffer tank, realizing the function of oxygen supply only when inhaling oxygen and no oxygen supply when not inhaling, avoiding continuous leakage of oxygen into the cabin. The oxygen inhalation resistance can be adjusted by changing the force of the balance component on the compensator, thereby achieving the purpose of adjustable oxygen inhalation resistance.

[0016] By setting up a balancing assembly consisting of a counterweight plate, a magnetic column, and an electromagnetic sleeve, the electromagnetic sleeve applies an electromagnetic force opposite to the gravity of the counterweight plate to the counterweight plate, so that the counterweight plate reaches a suspended equilibrium state, reducing the influence of the counterweight plate on the expansion or contraction of the compensator. Simply by changing the current introduced into the electromagnetic sleeve, the force exerted by the balancing assembly on the compensator can be changed, making the adjustment of the oxygen absorption resistance more convenient.

[0017] A one-way diaphragm is provided in the regulating valve. During the oxygen absorption process, the one-way diaphragm rises to allow the oxygen in the buffer tank to enter the air pressure chamber. When the oxygen absorption stops, the one-way diaphragm resets to prevent the oxygen in the air pressure chamber from flowing back into the buffer tank, thus having the function of preventing backflow. In addition, a first elastic electrode, a second elastic electrode and a diaphragm are provided in the regulating valve. During the oxygen inhalation process, the pressure in the air pressure chamber decreases, and the diaphragm is deformed, causing the first elastic electrode and the second elastic electrode to be disconnected, that is, the current introduced into the second excitation coil is disconnected. At this time, the upward force of the electromagnetic sleeve on the counterweight plate is reduced, and the counterweight plate presses down the compensator, causing the oxygen in the buffer tank to be discharged, and the oxygen enters the air pressure chamber. The air pressure in the air pressure chamber increases, the diaphragm is reset, the first elastic electrode and the second elastic electrode are connected, and the second excitation coil is energized. At this time, the upward force of the electromagnetic sleeve on the counterweight plate increases, and is balanced with the gravity of the counterweight plate again, and the active exhaust of the buffer tank stops. This design enables the respirator to have an oxygen exhaust function synchronized with the user's breathing rhythm, which not only greatly reduces the oxygen inhalation resistance, but also provides convenience for oxygen inhalation treatment of patients with weak breathing.

[0018] The respirator device proposed in the present invention has a rotating disk set in the regulating valve, and multiple groups of conductive components are set in the rotating disk. During the rotation of the rotating disk, the first elastic electrode and the second elastic electrode are intermittently connected through the conductive components, that is, the second excitation coil is energized and de-energized cyclically switched, so that the electromagnetic sleeve applies a continuously changing electromagnetic force opposite to the gravity of the counterweight disk to the counterweight disk, and the counterweight disk moves up and down to realize the function of active oxygen discharge. When in use, the rotation speed of the rotating disk is set, and oxygen can be discharged at the required frequency to meet the use needs of comatose patients. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] like Figures 1 to 10As shown, an embodiment of the present invention provides a medical air pressurized oxygen chamber respirator device, including a respirator body 1, with an oxygen inlet connector 2 and an oxygen inhalation connector 3 fixedly installed on both sides of the respirator body 1, a buffer tank 4 fixedly installed inside the respirator body 1, and an expandable or contractible compensator 5 fixedly installed on the surface of the buffer tank 4, the inner cavity of the compensator 5 is connected to the inner cavity of the buffer tank 4, the compensator 5 is a cylindrical air bag with a corrugated outer wall, which can be compressed and stretched in the vertical direction, and a mounting sleeve 6 fixedly installed inside the respirator body 1, and the compensator 5 is movably arranged in the mounting sleeve 6.

[0029] A balancing component is provided on the top of the mounting sleeve 6 , and the balancing component provides the compensator 5 with a force to overcome the deformation resistance of the compensator 5 itself.

[0030] The regulating valve 7 is fixedly installed inside the respirator body 1, and the oxygen inlet connector 2, the buffer tank 4, the regulating valve 7 and the oxygen inhalation connector 3 are connected in series. For details, refer to Figure 6 A pressure chamber 11 is provided inside the regulating valve 7, and an air intake ring 12 is embedded in the inner wall of the pressure chamber 11. The pressure chamber 11 is connected with the inner cavity of the buffer tank 4 through the inner hole of the intake ring 12, and the oxygen inhalation joint 3 is connected with the pressure chamber 11. A one-way diaphragm 13 is fixedly installed on the surface of the intake ring 12, and the one-way diaphragm 13 covers the inner hole of the intake ring 12. When the air pressure in the pressure chamber 11 is lower than the air pressure in the inner cavity of the buffer tank 4, the one-way diaphragm 13 is opened, and the intake ring 12 is in an open state. When the air pressure in the pressure chamber 11 is greater than or equal to the air pressure in the inner cavity of the buffer tank 4, the one-way diaphragm 13 covers the inner hole of the intake ring 12, and the intake ring 12 is in a closed state.

[0031] A one-way diaphragm 13 is provided in the regulating valve 7. During the oxygen absorption process, the one-way diaphragm 13 is tilted to allow the oxygen in the buffer tank 4 to enter the air pressure chamber 11. When the oxygen absorption stops, the one-way diaphragm 13 is reset to prevent the oxygen in the air pressure chamber 11 from flowing back into the buffer tank 4, thereby having an anti-backflow function.

[0032] like Figure 4 The balancing assembly includes a counterweight plate 8 and an electromagnetic sleeve 9. A magnetic column 10 is fixedly installed on the upper surface of the counterweight plate 8. The counterweight plate 8 is fixedly installed on the upper end of the compensator 5. The electromagnetic sleeve 9 is fixedly installed on the upper end of the mounting sleeve 6. The magnetic column 10 is slidably inserted in the electromagnetic sleeve 9.

[0033] The electromagnetic sleeve 9 is internally embedded with a first excitation coil 14 and a second excitation coil 15. When the first excitation coil 14 and the second excitation coil 15 are energized, they both generate a magnetic attraction force on the magnetic column 10 in the opposite direction to the gravity of the counterweight plate 8. Figure 4As shown, the above-mentioned magnetic attraction forces are F1 and F2 respectively, the sum of the gravity of the counterweight plate 8 and the magnetic column 10 is G, F1+F2=G, at this time the counterweight plate 8 is in a suspended equilibrium state, F1+F2<G, at this time the counterweight plate 8 presses down the compensator 5, providing the compensator 5 with a force to overcome the compensator 5's own deformation resistance.

[0034] In this embodiment, a vertical slide groove is provided on the inner wall of the mounting sleeve 6, and a sensing block 27 is fixedly installed on the surface of the counterweight plate 8. The sensing block 27 slides along the vertical slide groove, and a number of slot-type optical couplers 25 are embedded in the vertical slide groove. When the sensing block 27 blocks the sensing end of the slot-type optical coupler 25, the slot-type optical coupler 25 is triggered to send a signal.

[0035] A solenoid valve 26 is fixedly installed at the input end of the oxygen inlet connector 2, and the opening and closing of the solenoid valve 26 is controlled by signals from two slot-type optical couplers 25 located at the upper and lower ends.

[0036] During use, the medical oxygen cylinder is connected to the inlet of the solenoid valve 26 through a pipeline, and the oxygen inhalation connector 3 is connected to the oxygen inhalation mask through a bellows. The medical air pressurized oxygen chamber increases the pressure in the cabin by compressing air or injecting medical oxygen, so that the patient is in an environment higher than normal pressure. In this high-pressure environment, the patient wears an oxygen inhalation mask and breathes pure oxygen or high-concentration oxygen from the buffer tank 4 to achieve the treatment purpose.

[0037] refer to Figure 4 When the patient is breathing oxygen in the cabin, the oxygen in the buffer tank 4 decreases, the compensator 5 contracts, and the counterweight plate 8 moves to the lowest point, triggering the slotted optical coupler 25 at the lowest point. The slotted optical coupler 25 sends a signal to the CPLD, and the CPLD links the solenoid valve 26 to open. Then, the oxygen from the medical oxygen cylinder is injected into the buffer tank 4, the compensator 5 expands, and the counterweight plate 8 moves upward until the counterweight plate 8 moves to the highest point and triggers the slotted optical coupler 25 at the highest point. The slotted optical coupler 25 sends a signal to the CPLD, and the CPLD links the solenoid valve 26 to close. Figure 9 As shown; CPLD is used as the main control chip. CPLD has the characteristics of rich I / O ports, user-definable I / O ports, low cost, and easy implementation. Each slot-type optocoupler 25 signal is connected to the CPLD I / O port. CPLD controls whether the MOS tube of the MOS tube circuit is turned on or off according to the slot-type optocoupler 25 signal, thereby controlling the switch of the corresponding oxygen filling solenoid valve 26. Matrix LED light board (such as Figure 10 As shown in the figure, it is placed on the operating table outside the cabin and used by cabin medical staff to observe the patient's oxygen inhalation status. Since there are many LED lights on the matrix LED light board, the CPLD is connected to the serial input and parallel output shift registers, which is equivalent to realizing the expansion of I / O, and then controls all the LED lights on the matrix LED light board, as shown in the figure. Figure 9As shown, the position signal obtained by the slot-type optical coupler 25 determines whether the LED light is on or off, so that whether the compensator 5 is moving and the amplitude of the movement can be monitored in real time, and whether the patient is inhaling oxygen and the approximate amount of oxygen inhaled can be understood.

[0038] The respirator device proposed in the present invention is provided with a compensator 5 on the buffer tank 4, and a balancing component is used to provide the compensator 5 with a force to overcome the deformation resistance of the compensator 5 itself. When oxygen is injected into the buffer tank 4, the compensator 5 expands to reduce the internal air pressure. When the patient inhales oxygen, the compensator 5 contracts to reduce the oxygen inhalation resistance, thereby ensuring that the air pressure in the buffer tank 4 is close to the external atmospheric pressure. The patient always inhales the oxygen buffered in the buffer tank 4, realizing the function of oxygen supply only when inhaling oxygen and no oxygen supply when not inhaling oxygen, thereby avoiding continuous leakage of oxygen into the cabin. The oxygen inhalation resistance can be adjusted by changing the force of the balancing component on the compensator 5, thereby achieving the purpose of adjustable oxygen inhalation resistance.

[0039] By setting up a balancing component consisting of a counterweight plate 8, a magnetic column 10, and an electromagnetic sleeve 9, the electromagnetic sleeve 9 applies an electromagnetic force opposite to the gravity of the counterweight plate 8 to the counterweight plate 8, so that the counterweight plate 8 reaches a suspended equilibrium state, reducing the influence of the counterweight plate 8 on the expansion or contraction of the compensator 5. Only by changing the current introduced into the electromagnetic sleeve 9, the force exerted by the balancing component on the compensator 5 can be changed, making the adjustment of the oxygen absorption resistance more convenient.

[0040] In the present invention, an adjusting mechanism is provided inside the regulating valve 7 , and the force of the balancing component acting on the compensator 5 is controlled by the adjusting mechanism.

[0041] Specifically, the regulating mechanism includes a first elastic electrode 16, a second elastic electrode 17 and a diaphragm 18. A balancing chamber 19 connected to the outside atmosphere is provided inside the regulating valve 7. A communication window is provided between the balancing chamber 19 and the air pressure chamber 11. The diaphragm 18 is fixedly installed in the communication window. The balancing chamber 19 and the air pressure chamber 11 are separated by the diaphragm 18. The first elastic electrode 16 and the second elastic electrode 17 are both installed in the balancing chamber 19, and the second elastic electrode 17 is fixedly installed on the surface of the diaphragm 18. When the first elastic electrode 16 and the second elastic electrode 17 are electrically conductive, the power supply circuit of the second excitation coil 15 is conductive. Figure 6 、 Figure 8 .

[0042] Since the regulating valve 7 is provided with a first elastic electrode 16, a second elastic electrode 17 and a diaphragm 18, during the oxygen inhalation process, the pressure in the air pressure chamber 11 decreases, and the diaphragm 18 is deformed, causing the first elastic electrode 16 and the second elastic electrode 17 to be disconnected, that is, the current 15 introduced into the second excitation coil is disconnected. Figure 4, F2=0, at this time, the upward force of the electromagnetic sleeve 9 on the counterweight plate 8 is reduced, F1<G, the counterweight plate 8 presses down the compensator 5, causing the oxygen in the buffer tank 4 to be discharged, and the oxygen enters the air pressure chamber 11. The air pressure in the air pressure chamber 11 increases, the diaphragm 18 is reset, the first elastic electrode 16 and the second elastic electrode 17 are connected, and the second excitation coil 15 is energized. At this time, F1+F2=G, the upward force of the electromagnetic sleeve 9 on the counterweight plate 8 is increased, and it is balanced with the gravity of the counterweight plate 8 again, and the active exhaust of the buffer tank 4 stops. This design enables the respirator to have an oxygen discharge function synchronized with the user's breathing rhythm, which not only greatly reduces the oxygen inhalation resistance, but also provides convenience for oxygen inhalation treatment of patients with weak breathing.

[0043] In this embodiment, the regulating mechanism further includes a rotating disk 20 rotatably mounted in the balancing chamber 19. A servo motor 21 for driving the rotating disk 20 is fixedly mounted on the upper surface of the regulating valve 7. A plurality of conductive components are embedded in the interior of the rotating disk 20. The plurality of conductive components are arranged in a ring array, such as Figure 7 As shown, each group of conductive components includes an upper electrode sheet 22, a resistor element 23 and a lower electrode sheet 24 connected in series. The upper electrode sheet 22 and the lower electrode sheet 24 are respectively embedded in the upper and lower surfaces of the rotating disk 20. The first elastic electrode 16 and the second elastic electrode 17 are respectively in sliding contact with the upper and lower surfaces of the rotating disk 20. When the rotating disk 20 rotates, the first elastic electrode 16 can contact the upper electrode sheet 22, and the second elastic electrode 17 can contact the lower electrode sheet 24. Figure 8 At this time, the power supply circuit of the second excitation coil 15 is turned on, and the second excitation coil 15 generates a force F2. As the servo motor 21 drives the rotating disk 20 to rotate, when the first elastic electrode 16, the second elastic electrode 17 and the upper electrode sheet 22, and the lower electrode sheet 24 are offset, F2=0, F1+0<G, the counterweight plate 8 presses down the compensator 5, causing the oxygen in the buffer tank 4 to be discharged.

[0044] The ventilator device proposed in the present invention has a rotating disk 20 provided inside the regulating valve 7, and multiple sets of conductive components are provided inside the rotating disk 20. During the rotation of the rotating disk 20, the first elastic electrode 16 and the second elastic electrode 17 are intermittently conductive through the conductive components, that is, the second excitation coil 15 is cyclically switched between power on and power off, so that the electromagnetic sleeve 9 applies a continuously changing electromagnetic force opposite to the gravity of the counterweight disk 8 to the counterweight disk 8, and the counterweight disk 8 moves up and down, realizing the function of active oxygen discharge. When in use, the speed of the rotating disk 20 is set, and oxygen can be discharged at the required frequency to meet the use needs of comatose patients.

[0045] The resistance values ​​of the resistor elements 23 of the plurality of conductive components are increased in sequence. Figure 7R1, R2, and R3 are resistance elements 23. Taking R1<R2<R3 as an example, during the rotation of the rotating disk 20, the first elastic electrode 16 and the second elastic electrode 17 are turned on in turn through R1, R2, and R3 in the resistance element 23. The current is inversely proportional to the resistance. The resistance value of the resistance element 23 increases, and the current flowing into the second excitation coil 15 gradually decreases, causing the F2 generated by the second excitation coil 15 to gradually decrease, F1+F2↓=G, that is, the pressure Fp of the counterweight disk 8 on the compensator 5 is gradually increasing. Due to the compression process of the compensator 5, the compressive resistance Fk of the compensator 5 on the counterweight disk 8 is gradually increasing. The resistance value of each resistance element 23 is reasonably selected to ensure that the increments of Fp and Fk are consistent. The compensator 5 is compressed to different degrees, so that the counterweight disk 8 can reach a suspended equilibrium state again, ensuring the stability of the air pressure in the buffer tank 4, solving the problem that the deformation resistance of the compensator 5 itself changes greatly and affects the oxygen inhalation resistance, making the patient's oxygen inhalation smoother and meeting the use needs of oxygen inhalation treatment for different patients.
