[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention controls the oxygen flow rate provided by the oxygen tank by setting up an automatic flow regulator and a high-precision regulator. A miniature finger pulse oximeter detects the patient's pulse oximetry saturation. Based on the detection results, a PLC module controls and adjusts the automatic flow regulator and the high-precision regulator. A stepper motor drives a reduction gear to rotate, which in turn moves two mechanical adjustment valve plates. The movement of the mechanical adjustment valve plates adjusts the size of the opening, allowing the oxygen flow rate to be precisely adjusted according to the sealing teeth. The combination of stepper motor-controlled reduction gear and mechanical adjustment valve plate ensures high precision, high reliability, and stability in flow regulation, which is superior to the adjustment method relying solely on solenoid valves. Through closed-loop control, the PLC module, in conjunction with the miniature finger pulse oximeter, can respond to changes in the patient's pulse oximetry in real time, automatically adjusting the oxygen flow rate to the optimal level. This avoids hypoxemia or oxygen toxicity caused by untimely adjustment in traditional methods. It features multi-level control of the tank valve, solenoid valve, automatic flow regulator, and secondary flow valve, resulting in stronger system fault tolerance.

[0019] 2. This invention provides additional flow regulation and safety assurance through a secondary flow valve, and the solenoid valve located at the rear of the wall-mounted plate, with pressure gauge detection, enables the on / off control of the gas source and pressure monitoring, improving the overall reliability of the system. This frees medical staff from the repetitive work of frequently monitoring pulse oxygen and manually adjusting flow, achieving unattended automatic oxygen therapy, allowing medical staff to focus on more core medical tasks. Each component has a clearly defined function and interface, facilitating production, assembly, and maintenance. The standard interface on the wall-mounted plate allows this device to be quickly installed on existing hospital oxygen supply systems, resulting in low modification costs and easy promotion.

[0020] 3. This invention transmits pulse oxygen, flow, and pressure data to a mobile terminal via a wireless transmission module, allowing medical staff to remotely monitor the status of multiple patients, enabling proactive intervention and timely detection of abnormal trends. Furthermore, the treatment data from this device can provide objective and continuous evidence for clinical research, efficacy evaluation, and treatment plan development, upgrading traditional open oxygen therapy into a precise, automatic, and safe closed-loop management device. This not only improves the treatment effect and safety for patients but also brings efficiency improvements and resource savings to medical institutions through intelligence and automation.

[0021] 4. This invention features a detachable connection between the oxygen conduit and the connector. When the oxygen conduit transmits oxygen, the pressure of the oxygen pushes the push plate inside the sealing hole to move outward, thereby compressing the gas inside the sealing hole. The gas inside the sealing hole flows into the elastic airbag ring through the air tube. The elastic airbag ring expands and comes into close contact with the inner wall of the connector, improving the sealing performance of the connection and preventing oxygen leakage during delivery. The outward movement of the push plate also drives the contact rod to slide closer to the connector, making the contact rod contact the inner wall of the connector, enhancing the connection between the oxygen conduit and the inner wall of the connector, and improving the reliability of the connection.

[0022] 5. By setting an adjustment component, the present invention can automatically adjust the gas flow rate according to the gas flow pressure entering the exhaust pipe, ensuring stable airflow and avoiding repeated rises and falls in oxygen pulse due to flow fluctuations.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0026] To address the problem that existing oxygen flow regulation devices suffer from a simplistic flow regulation structure, poor adjustment of oxygen channel size, and inability to meet actual medical needs during practical use, please refer to... Figure 1 , Figure 3 - Figure 6 This embodiment provides the following technical solution: The intelligent oxygen inhalation device, which integrates wireless transmission and automatic oxygen flow regulation, includes an oxygen tank 1, an adjusting three-way tube 3, and a miniature finger pulse oxygen monitor 6. An air delivery tube 102 is provided on the oxygen tank 1, and the air delivery tube 102 is connected to the adjusting three-way tube 3. An automatic flow regulator 305 is installed at the lower end of the regulating three-way pipe 3. A high-precision regulator 307 and a stepper motor 308 are installed at the rear end of the automatic flow regulator 305. Mechanical adjustment valve plates 3074 are provided at the upper and lower ends of the high-precision regulator 307. A secondary flow valve 4 is provided at the lower end of the regulating three-way pipe 3. An oxygen mask 5 is connected to the secondary flow valve 4. The miniature finger pulse oximeter 6 is connected to the automatic flow regulator 305 via a PLC module. The miniature finger pulse oximeter 6 has an external adjustment shaft 601 and an internal memory metal spring 602. By setting the automatic flow regulator 305 and the high-precision regulator 307, the oxygen flow provided by the oxygen tank 1 is controlled. The miniature finger pulse oximeter 6 detects the patient's pulse oximeter saturation. Based on the detection results, the automatic flow regulator 305 and the high-precision regulator 307 are adjusted by the PLC module.

[0027] The high-precision regulator 307 is equipped with an air inlet pipe 3072 at its upper end, which is sealed to the exhaust pipe 304. The high-precision regulator 307 is equipped with an air outlet pipe 3071 at its lower end. An oxygen conduit 402 is installed between the lower end of the air outlet pipe 3071 and the secondary flow valve 4. The oxygen conduit 402 is sealed to both the air outlet pipe 3071 and the secondary flow valve 4. With the multi-stage control of the tank valve 101, solenoid valve 202, automatic flow regulator 305 and secondary flow valve 4, the system has stronger fault tolerance.

[0028] It should be noted that the high-precision regulator 307 has a stepped plate 3073 sealed to both its upper and lower ends. An integrally formed retainer 3075 is horizontally arranged on the outside of the stepped plate 3073. The mechanical adjustment valve plate 3074 is slidably and sealed to the stepped plate 3073 through the retainer 3075. An integrally formed opening 3077 is provided inside the stepped plate 3073. The opening 3077 is connected to the outlet pipe 3071 and the inlet pipe 3072. The stepper motor 308 drives the reduction gear 3081 to rotate. The reduction gear 3081 drives the two mechanical adjustment valve plates 3074 to move. The movement of the mechanical adjustment valve plates 3074 will adjust the size of the opening 3077, so that the oxygen flow of the opening 3077 is precisely adjusted according to the sealing teeth 3076.

[0029] In addition, a reduction gear 3081 is installed at the rear end of the high-precision regulator 307. The stepper motor 308 is fixedly connected to the high-precision regulator 307 by fixing screws. The motor shaft of the stepper motor 308 is connected to the reduction gear 3081 for transmission. The mechanical adjustment valve plate 3074 is provided with sealing teeth 3076 inside. The reduction gear 3081 is meshed with the sealing teeth 3076. The stepper motor 308 controls the reduction gear 3081 to regulate the mechanical adjustment valve plate 3074, ensuring high precision, high reliability and stability of flow regulation, which is superior to the regulation method that relies solely on solenoid valves. Through closed-loop control, the PLC module, together with the miniature finger pulse oxygen monitor 6, can respond to changes in the patient's pulse oxygen in real time and automatically adjust the oxygen flow to the most suitable level, avoiding hypoxemia or oxygen toxicity caused by untimely adjustment in the traditional method.

[0030] In fact, the automatic flow regulator 305 is sealed to the high-precision regulator 307. The automatic flow regulator 305 has a clamping frame 309 installed inside. An electric cylinder 3091 is installed between the clamping frames 309. Clutch blocks 3092 are installed on both sides of the clamping frame 309. The clutch blocks 3092 are engaged with the reduction gear 3081. After adjustment, the electric cylinder 3091 drives the clamping frame 309 and the clutch blocks 3092 to move. The clutch blocks 3092 fix the reduction gear 3081. After the reduction gear 3081 is fixed, the mechanical adjustment valve plate 3074 locks the position of the port 3077, thereby fixing the flow port size and realizing high-precision adjustment.

[0031] Specifically, the oxygen flow rate supplied by oxygen tank 1 is controlled by setting an automatic flow regulator 305 and a high-precision regulator 307. The patient's pulse oximetry saturation is detected by a miniature finger pulse oximeter 6. Based on the detection results, the automatic flow regulator 305 and the high-precision regulator 307 are adjusted via a PLC module. A stepper motor 308 drives a reduction gear 3081 to rotate, which in turn moves two mechanical adjustment valve plates 3074. The movement of the mechanical adjustment valve plates 3074 adjusts the size of the inlet 3077, thus controlling the oxygen flow rate through the inlet 3077 according to the sealing teeth 3. The 076 system performs precise adjustments. The combination of stepper motor 308 controlling reduction gear 3081 and regulating mechanical adjustment valve plate 3074 ensures high precision, high reliability, and stability of flow regulation, which is superior to the adjustment method that relies solely on solenoid valves. Through closed-loop control, the PLC module, in conjunction with the miniature finger pulse oxygen monitor 6, can respond to changes in the patient's pulse oxygen in real time and automatically adjust the oxygen flow to the most suitable level. This avoids hypoxemia or oxygen toxicity caused by untimely adjustment in traditional methods. It features multi-level control of tank valve 101, solenoid valve 202, automatic flow regulator 305, and secondary flow valve 4, making the system more fault-tolerant.

[0032] To address the issue that existing oxygen flow regulation devices are structurally simplistic, require long-term monitoring by medical staff, and thus impact medical needs, please refer to... Figure 1 - Figure 4 This embodiment provides the following technical solution: In this embodiment, the upper end of the oxygen cylinder 1 is equipped with a cylinder valve 101, which is sealed to the air delivery pipe 102. The upper end of the air delivery pipe 102 is connected to a wall mounting plate 2, which is hung on the wall. Through the standard interface set in the wall mounting plate 2, this device can be quickly installed on the existing hospital oxygen supply system, with low modification cost and easy promotion. In addition, the pulse oxygen, flow rate and pressure data are sent to the mobile terminal through the wireless transmission module 201, allowing medical staff to remotely monitor the status of multiple patients, realize proactive intervention, and promptly detect abnormal trends.

[0033] The wall mounting plate 2 has a wireless transmission module 201, a solenoid valve 202, and a circuit board 203 installed at its rear end. The circuit board 203 is connected to the PLC module, the solenoid valve 202 is sealed to the air duct 102, and the wireless transmission module 201 is used to transmit data to the mobile terminal. This frees medical staff from the repetitive work of frequently monitoring pulse oxygen and manually adjusting the flow rate, realizing unattended automatic oxygen therapy. This allows medical staff to focus on more core medical tasks. Each component has a clear function and a clear interface, which facilitates production, assembly, and maintenance.

[0034] It should be noted that a valve knob 301 is installed between the adjusting tee pipe 3 and the wall mounting plate 2, and an indicator light 302 is provided at the front end of the adjusting tee pipe 3.

The secondary flow valve 4 provides additional flow regulation and safety assurance. Furthermore, the solenoid valve 202 installed at the rear end of the wall mounting plate 2 uses a pressure gauge 306 to detect the on / off of the gas source and monitor the pressure, thereby improving the overall reliability of the system.

[0037] Specifically, the secondary flow valve 4 provides additional flow regulation and safety assurance, and the solenoid valve 202 located at the rear end of the wall-mounted plate 2, through pressure gauge 306, enables the on / off control of the gas supply and pressure monitoring, improving the overall reliability of the system. This frees medical staff from the repetitive work of frequently monitoring pulse oximetry and manually adjusting flow, achieving unattended automatic oxygen therapy, allowing medical staff to focus on more core medical tasks. Each component has a clearly defined function and interface, facilitating production, assembly, and maintenance.

Through intelligence and automation, it also brings significant efficiency improvements and resource savings to medical institutions.

[0038] Please see Figure 7 , Figure 8This embodiment provides the following technical solution: The lower end of the oxygen conduit 402 is connected to the transmission hose 503 via a connector 701. The connector 701 is fixedly connected to the upper end of the transmission hose 503. A stepped hole 702 is provided inside the connector 701. The lower end of the oxygen conduit 402 is inserted into the connector 701 and contacts the stepped portion of the stepped hole 702. A sliding hole is provided on the side wall of the connector 701. A insertion ring groove 703 corresponding to the sliding hole is provided on the outer wall of the oxygen conduit 402. An insertion rod 704 is slidably disposed in the sliding hole. One end of the insertion rod 704 extends into the insertion ring groove 703, and the other end of the insertion rod 704 extends to the outside of the connector 701 and is provided with a pull plate 705. A first spring 706 is sleeved on the outside of the insertion rod 704. One end of the first spring 706 is connected to the outer wall of the connector 701, and the other end of the first spring 706 is connected to the pull plate 705. The connection includes an upward-sloping end of the plug rod 704 near the oxygen conduit 402. Several sealing holes 707 are provided on the side wall of the oxygen conduit 402. The sealing holes 707 are connected to the outer wall of the oxygen conduit 402 via connecting holes. The diameter of the connecting holes is smaller than the diameter of the sealing holes 707. A push plate 708 is provided inside the sealing hole 707. A contact rod 709 is provided on the side of the push plate 708 near the connector 701. One end of the contact rod 709 passes through the connecting hole and contacts the inner wall of the connector 701. A second spring 710 is provided outside the contact rod 709. One end of the second spring 710 is connected to the push plate 708, and the other end is connected to the inner wall of the sealing hole 707. A sealing ring groove is also provided on the side wall of the oxygen conduit 402. An elastic airbag ring 711 is provided inside the sealing ring groove. The elastic airbag ring 711 is connected to the sealing hole 707 via an air tube 712.

[0039] Specifically, a rigid connector 701 is fixedly connected to the upper end of the transmission hose 503. When the transmission hose 503 is connected to the oxygen conduit 402, the lower end of the oxygen conduit 402 is first inserted into the connector 701. The oxygen conduit 402 contacts the inclined surface of the insertion rod 704 and drives the insertion rod 704 to move outward. When the lower end of the oxygen conduit 402 contacts the stepped part of the connector 701, under the elastic force of the first spring 706, the insertion rod 704 can be inserted into the insertion ring groove 703, thereby realizing the detachable connection between the oxygen conduit 402 and the connector 701. When the oxygen conduit 402 transmits oxygen, the pressure of the oxygen can push the push plate 708 in the sealing hole 707 to move outward, thereby squeezing the gas in the sealing hole 707. The gas in the sealing hole 707 flows into the elastic airbag ring 71 through the air tube 712. Inside, the elastic airbag ring 711 expands and comes into close contact with the inner wall of the connector 701, improving the sealing of the connection and preventing oxygen leakage during delivery. The push plate 708 moves outward and simultaneously drives the contact rod 709 to slide closer to the connector 701, so that the contact rod 709 contacts the inner wall of the connector 701, enhancing the connection between the oxygen conduit 402 and the inner wall of the connector 701, and improving the reliability of the connection. When disassembling, oxygen delivery stops, and under the elastic force of the second spring 710, the push plate 708 returns to its original position, the contact rod 709 separates from the inner wall of the connector 701, the elastic airbag ring 711 contracts, and pulls the pull plate 705 outward, so that the plug rod 704 separates from the plug ring groove 703, which can quickly separate the connector 701 from the oxygen conduit 402, facilitating the quick assembly and disassembly of the oxygen conduit 402 and the transmission hose 503.

Two guide spiral blades 802 are fixedly installed on the annular sliding plate 801. An adjustment pipe 803 is provided at the bottom of the annular sliding plate 801. The adjustment pipe 803 is made of a flexible material and is hourglass-shaped. The upper end of the adjustment pipe 803 is connected to the bottom of the annular sliding plate 801, and the lower end of the adjustment pipe 803 is connected to the bottom inner wall of the exhaust pipe 304. Several connecting plates 804 are provided on the outer wall of the middle position of the adjustment pipe 803. A first rack 805 is horizontally installed at the end of the connecting plate 804 away from the adjustment pipe 803. A groove 806 is provided on the inner wall of the air pipe 304. The end of the first rack 805 away from the connecting plate 804 extends into the groove 806 and is horizontally slidably connected to the inner wall of the groove 806. A gear column 807 is provided between the adjusting pipe 803 and the inner wall of the exhaust pipe 304. The front and rear ends of the gear column 807 are rotatably connected to the inner wall of the exhaust pipe 304, respectively. The upper side of the gear column 807 meshes with the first rack 805. A second rack 808 corresponding to the first rack 805 is provided on the lower surface of the annular slide plate 801. The second rack 808 is vertically arranged. The side of the second rack 808 near the connecting plate 804 meshes with the gear column 807. The lower end of the second rack 808 is connected to the bottom inner wall of the exhaust pipe 304 through a third spring 809.

[0041] Specifically, when the airflow pressure flowing into the exhaust pipe 304 is high, the airflow flows downward along the guide spiral blades 802, thus guiding the airflow. Simultaneously, the airflow pushes the annular slide plate 801 downward through the guide spiral blades 802. The annular slide plate 801 drives the second rack 808 to move downward synchronously, and the third spring 809 is gradually compressed. The second rack 808 drives the gear column 807 to rotate, and the gear column 807 drives the first rack 805 to slide into the groove 806. The first rack 805 drives the connecting plate 804 to move closer to the groove 806, thereby causing the middle part of the regulating pipe 803 to move closer to the groove 806. The cross section at the middle position of the regulating pipe 803... The area is increased accordingly, thereby slowing down the airflow velocity and preventing the airflow from being too fast and causing harm to the patient. When the airflow pressure flowing into the exhaust pipe 304 is low, under the elastic force of the third spring 809, the annular slide plate 801 slides upward to return to its original position. The first rack 805 drives the middle part of the regulating pipe 803 to move away from the slide groove 806 through the connecting plate 804, so that the cross-sectional area of ​​the middle position of the regulating pipe 803 is reduced accordingly, thereby increasing the airflow velocity and providing the patient with a stable flow of oxygen. By setting the regulating component, the gas flow rate can be automatically adjusted according to the airflow pressure entering the exhaust pipe 304 to ensure a stable airflow and avoid repeated rises and falls in pulse oxygen due to flow fluctuations.

[0042] Working principle: In use, the miniature finger pulse oximeter 6 is fixed to the patient's finger via the adjusting shaft 601. After the patient wears an oxygen mask 5, the miniature finger pulse oximeter 6 collects the patient's pulse oximeter saturation data in real time, ensuring that the monitoring accuracy meets medical standards. Based on the test results, the automatic flow regulator 305 and the high-precision regulator 307 are adjusted by the PLC module. The stepper motor 308 drives the reduction gear 3081 to rotate, which in turn drives the two mechanical adjusting valve plates 3074 to move. The movement of the mechanical adjusting valve plates 3074 adjusts the size of the opening 3077, so that the oxygen flow rate of the opening 3077 is adjusted according to the sealing teeth 307. 6. Precise adjustment is achieved through a combination of stepper motor 308 controlling reduction gear 3081 and regulating mechanical adjustment valve plate 3074, ensuring high precision, high reliability, and stability of flow regulation. This is superior to adjustment methods that rely solely on solenoid valves. Through closed-loop control, the PLC module, paired with a miniature finger pulse oximeter 6, can respond in real time to changes in the patient's pulse oximetry and automatically adjust the oxygen flow to the optimal level. This avoids hypoxemia or oxygen toxicity caused by untimely adjustment in traditional methods. The system features multi-level control via tank valve 101, solenoid valve 202, automatic flow regulator 305, and secondary flow valve 4, resulting in stronger system fault tolerance. The multi-stage oxygen control system, featuring a dynamic flow regulator 305 and a secondary flow valve 4, offers enhanced system fault tolerance. The secondary flow valve 4 provides additional flow regulation and safety assurance. Furthermore, the solenoid valve 202 at the rear of the wall-mounted plate 2, monitored by a pressure gauge 306, controls the gas supply's on / off state and pressure, improving overall system reliability. This frees medical staff from the repetitive tasks of frequently monitoring pulse oximetry and manually adjusting flow, enabling unattended automated oxygen therapy. This allows medical staff to focus on core medical tasks. Each component has a clearly defined function and interface, facilitating production, assembly, and maintenance. The standard interface on the wall-mounted plate 2 allows for... This device can be quickly installed on existing hospital oxygen supply systems with low modification costs and is easy to promote. In addition, it transmits pulse oxygen, flow, and pressure data to mobile terminals via wireless transmission module 201, allowing medical staff to remotely monitor the status of multiple patients, enabling proactive intervention and timely detection of abnormal trends. Furthermore, the treatment data from this device can provide objective and continuous evidence for clinical research, efficacy evaluation, and personalized treatment plan development, upgrading traditional open oxygen therapy into a precise, automatic, and safe closed-loop management device. This not only directly improves the treatment effect and safety of patients but also brings efficiency improvements and resource savings to medical institutions through intelligence and automation.
