Description

Technical Field

[0001] The invention belongs to the technical field of medical oxygen supply equipment, in particular to a detachable oxygen absorption temperature and humidity regulating device for an oxygen absorption tank. Background Art

[0002] An oxygen inhaler, also known as an oxygen tank, is a device that loads compressed oxygen and delivers oxygen to the user's respiratory system through pipes. It is suitable for scenarios such as medical first aid, altitude sickness, exercise recovery, and relief of mental fatigue.

[0003] Oxygen tubes are mainly composed of high-pressure oxygen cylinders: usually steel cylinders or aluminum cylinders, filled with compressed oxygen with a purity of more than 99.5%.

[0004] Pressure reducing valve: reduces high-pressure oxygen to a safe operating pressure.

[0005] Flow regulating valve: controls the oxygen output flow.

[0006] Humidifier bottle: humidify oxygen with distilled water or boiled water to avoid dryness of the respiratory tract.

[0007] Oxygen mask / nasal cannula: directly contacts the user's mouth and nose to deliver oxygen.

[0008] The working process is: oxygen is reduced in pressure from the gas cylinder through the pressure reducing valve → the flow is controlled by the flow regulating valve → humidified by the humidifier bottle → transported to the mask or nasal suction tube through the pipeline.

[0034] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0035] As attached Figure 1 To the attached Figure 8 As shown:

[0036] Embodiment 1: The present invention provides a detachable oxygen absorption temperature and humidity regulating device for an oxygen absorption tank, comprising a heating shell 1 and a humidifying shell 2. The bottom of the heating shell 1 is provided with a heat insulating ring 3, and the heat insulating ring 3 and the humidifying shell 2 are detachably connected. A heat conducting plate 4 is provided on the outer wall of the heating shell 1, and a ring-shaped heating wire 5 is provided inside the heat conducting plate 4. A water storage box 6 is provided at the bottom end of the humidifying shell 2, and a fiber wet membrane 7 is provided inside the water storage box 6.

[0037] It also includes an oxygen outlet pipe 8 and an oxygen inlet pipe 9. The oxygen inlet pipe 9 is installed on the top of the heating shell 1, and the oxygen outlet pipe 8 is installed on the side wall of the humidifying shell 2. A sealing disassembly component is provided between the heating shell 1 and the insulation ring 3.

[0038] It should be noted that, through the setting of the heating shell 1 and the humidifying shell 2, a heat conducting plate 4 is provided on the outer wall of the heating shell 1, and a heating wire 5 connected to the heat conducting plate 4 is provided. The heating wire 5 is energized, so that the heat conducting plate 4 is heated by the heating wire 5, and the heat is transferred to the heating shell 1. After the oxygen is sent into the heating shell 1 from the oxygen inlet pipe 9, the oxygen can be heated. After the heating is completed, the oxygen will downwardly enter the humidifying shell 2. A water storage box 6 containing sterile water is placed inside the humidifying shell 2. A fiber wet membrane 7 is provided in the water storage box 6 in contact with the sterile water. The oxygen flows through the surface of the wet fiber wet membrane 7. The fiber wet membrane 7 adopts a hydrophilic nano material. The fiber wet membrane 7 is humidified by natural evaporation and finally comes out from the oxygen outlet pipe 8, thereby completing the temperature and humidity adjustment of the oxygen to adapt to different environmental requirements.

[0039] Moreover, an insulating ring 3 is fixedly installed on the bottom of the heating shell 1, and the insulating ring 3 is detachably connected to the humidifying shell 2. Therefore, when the upper components of the heating shell 1 and the upper components of the humidifying shell 2 are damaged, the heating shell 1 and the humidifying shell 2 can be separated without replacing them as a whole, reducing maintenance costs, and they can be disassembled when not in use for easy carrying.

[0040] In this embodiment, the heating shell 1 and the humidifying shell 2 are both cylindrical in design, and the opening diameter of the internal chamber of the heating shell 1 near the upper and lower ends is larger than the opening diameter of the middle section. A locking portion 10 is provided at one end of the oxygen inlet pipe 9, and the locking portion 10 is fixed to the heating shell 1 by means of threads.

[0041] It should be noted that, by designing the interior of the heating shell 1 to have large openings at both ends and a small opening in the middle, the heating area is located in the middle section, so that after the oxygen enters the interior of the heating shell 1, the internal diameter of the heating shell 1 gradually shrinks, which will make the oxygen relatively concentrated, thereby centrally heating the oxygen and improving the heating effect; one end of the oxygen inlet pipe 9 is connected to the oxygen supply pipe of the oxygen tank, and the other end is provided with a locking part 10, and the locking part 10 is provided with a thread connected to the heating shell 1, so that the heating shell 1 and the oxygen inlet pipe 9 can be disassembled, which is convenient for separating the two later and cleaning the interior.

[0042] In this embodiment, the heating shell 1 is fixedly connected to the insulation ring 3, and a ring-shaped matching groove 11 is provided at the bottom of the insulation ring 3. A fixedly connected magnetic ring 12 is provided at the top of the matching groove 11, and a rubber ring 13 is provided on the relative inner wall of the matching groove 11. The top of the humidifying shell 2 is provided with a docking portion 14, and a magnetic ring 2 15 is provided at the top of the docking portion 14. The docking portion 14 is inserted into the matching groove 11 and fits with the rubber ring 13, and the magnetic ring 12 and the magnetic ring 2 15 are adsorbed on each other.

[0043] It should be noted that the magnetic ring 12 is fixedly connected in the matching groove 11, and the magnetic ring 2 15 is fixedly connected to the docking part 14. When the heating shell 1 and the humidifying shell 2 need to be connected, the docking part 14 on the top of the humidifying shell 2 is inserted into the matching groove 11, and the two sides of the docking part 14 fit together with the sealing ring. The sealing ring is made of rubber material. When the docking part 14 is inserted into the innermost part of the matching groove 11, the magnetic ring 12 and the magnetic ring 2 15 are adsorbed together. Through the connection method of magnetic attraction and the sealing ring, the heating shell 1 and the humidifying shell 2 can be connected together to achieve quick disassembly, and the sealing between the two is guaranteed to avoid oxygen leakage.

[0044] In this embodiment, the heating shell 1 is made of metal material, and the heat conducting plate 4 is made of aluminum alloy material. The heat conducting plate 4 and the heating shell 1 are fitted together. The heat conducting plate 4 is installed in a ring-shaped interval manner on the upper half of the heating shell 1, and the heat conducting plate 4 is installed in multiple layers on the lower half of the heating shell 1, and is installed in an overall ring-shaped manner.

[0045] It should be noted that by designing the heating shell 1 to be made of metal, heat can be transferred so that the heat enters the interior of the heating shell 1 to heat the oxygen.

[0046] In this embodiment, the heating wire 5 is distributed in a ring shape on the outer wall of the heat conducting plate 4, and is made of nickel-chromium alloy resistance wire. The heating wire 5 is distributed in multiple layers on the heat conducting plate 4, and the number installed on the upper half of the heat conducting plate 4 is greater than the number on the lower half of the heat conducting plate 4. A ring-shaped high-temperature resistant dot glue 16 is provided between the heating wire 5 and the heat conducting plate 4, and an annular heat insulation plate 17 is provided on the outside of the heating shell 1. There is a gap between the annular heat insulation plate 17 and the heating wire 5, and the top and bottom are fixed on the heating shell 1.

[0047] It should be noted that, by providing the heating wire 5, the heat generated by the heating wire 5 after being powered on can be transferred to the heat conducting plate 4, and the distribution density of the heating wire 5 in the upper half of the heat conducting plate 4 is greater than that in the lower half of the heat conducting plate 4, so that when the oxygen first enters the heating shell 1, it can be heated more concentratedly, so that the temperature of the oxygen increases, and after the oxygen gradually moves downward, the number of heating wires 5 decreases, thereby maintaining the oxygen temperature and keeping the oxygen temperature stable.

[0048] In this embodiment, the sealing and disassembly assembly includes a mounting ring 18, a mounting frame 20, a positioning rod 21, a positioning spring 22 and a baffle 23. The mounting ring 18 is fixedly connected to the top outer wall of the humidifier shell 2. The mounting ring 18 is provided with an annularly distributed plug-in holes 19. The mounting frame 20 is symmetrically fixedly connected to the outer wall of the insulation ring 3. The interior of the mounting frame 20 is provided with a accommodating chamber 24. The positioning rod 21 vertically moves through the mounting frame 20 and cooperates with the plug-in holes 19.

[0049] In this embodiment, the baffle 23 is fixedly connected to the positioning rod 21 and is in the accommodating chamber 24. A baffle 25 is provided on the top of the positioning rod 21. The positioning spring 22 is sleeved on the positioning rod 21 and is in the accommodating chamber 24. The bottom of the positioning spring 22 abuts against the baffle 23, and the top abuts against the top of the installation chamber.

[0050] It should be noted that, through the provided sealing and disassembly assembly, the positioning spring 22 is sleeved on the positioning rod 21 and is in the installation chamber. Under normal circumstances, the positioning spring 22 abuts against the baffle 23, and the baffle 23 contacts the bottom of the installation chamber, so that the positioning rod 21 passes through the installation frame 20 and is inserted into the plug hole 19 of the installation ring 18. There are multiple plug holes 19. Since the oxygen outlet pipe 8 is fixedly connected to the humidification housing 2, the other end of the oxygen outlet pipe 8 is connected to the oxygen supply pipe. Therefore, the angle of the oxygen outlet pipe 8 can be adjusted by rotating the humidification housing 2, so as to better dock with the oxygen supply pipe. After the positioning rod 21 is inserted into the plug hole 19, loosening of the heating housing 1 and the humidification housing 2 can be avoided, which not only improves the flexibility between the two, but also improves the firmness of the connection.

[0051] When the two need to be separated, it is only necessary to pull the baffle 25 upwards. The baffle 25 is fixedly connected to the positioning rod 21, driving the positioning rod 21 out of the plug hole 19, and the positioning spring 22 contracts. Then the heating shell 1 and the humidifying shell 2 can be disassembled from each other. If there is insufficient sterile water in the water storage box 6 at a later time, the heating shell 1 and the humidifying shell 2 can be quickly separated, and then water can be added without stopping the oxygen tank from supplying oxygen. In an emergency, the safety of oxygen supply is improved.

[0052] In this embodiment, a guide plate 26 is provided on the inner wall of the humidifying shell 2 and near the top. The vertical cross-sectional profile of the guide plate 26 is a horizontal "L" shape, and the top plate of the guide plate 26 is a semicircular plate with an area of ​​half the internal cross-sectional area of ​​the humidifying shell 2. A horizontal guide plate 27 is provided at the bottom of the vertical plate of the guide plate 26. The guide plate extends toward the guide plate 26 and a guide gap 28 is formed between the guide plate and the inner wall of the humidifying shell 2. The oxygen outlet pipe 8 is located between the top of the guide plate 26 and the guide plate 2 27.

[0053] It should be noted that the guide plate 1 26 is fixedly connected to the inside of the humidifying housing 2, and the cross-sectional area of ​​the top plate of the guide plate 1 26 is half of the cross-sectional area of ​​the inside of the humidifying housing 2. The guide plate 27 is fixedly connected to the bottom of the guide plate 1 26. Therefore, after the oxygen is heated, it will flow along the gap between the guide plate 1 26 and the humidifying housing 2, gradually downward to contact the fiber wet membrane 7, and then flow along the guide plate 27. The guide plate 27 is located above the fiber wet membrane 7, thereby increasing the contact area between the oxygen and the fiber wet membrane 7, which can better humidify the oxygen and improve the humidification effect of the oxygen.

[0054] By setting a guide gap 28 between the guide plate 2 and the humidification shell 2, the oxygen can pass through the guide gap 28 after humidification and enter between the guide plate 1 26 and the guide plate 2 27, and finally exit from the oxygen outlet pipe 8, completing the heating and humidification of the oxygen.

[0055] In this embodiment, the water storage box body 6 is made of glass, and a transparent portion 29 is provided on the outer wall of the humidifying shell 2, and the transparent portion 29 is opposite to the water storage box body 6. A temperature sensor 30 with a probe extending to the interior of the heating shell 1 is provided on the outer wall of the annular heat insulation plate 17, and a humidity sensor 31 with a probe extending to the interior is provided on the outer wall of the humidifying shell 2. A power supply 32 is provided at the bottom of the humidifying shell 2, and the power supply 32 is electrically connected to the heating wire 5, the temperature sensor 30 and the humidity sensor 31. The power supply 32 is powered by a battery.

[0056] It should be noted that the water storage box 6 is designed to be made of glass, so that it can cooperate with the transparent part 29. The water level of the sterile water in the water storage box 6 can be observed from the outside. When the water level is low, it can be replenished in time. The temperature and humidity of the oxygen can be monitored after heating and humidification by the provided temperature sensor 30 and humidity sensor 31.

[0057] The working process of the temperature sensor 30 is as follows: for temperature detection, the resistance of the NTC thermistor changes with temperature, which is converted into a voltage signal through a voltage divider circuit. The signal is input into a microcontroller (such as STM32) through an analog-to-digital converter. The microcontroller calculates the real-time temperature value according to the NTC characteristic table (table lookup method), compares it with the set temperature (such as 35°C), calculates the deviation value, and then adjusts the heating power through the PID algorithm;

[0058] The heating wire 5 is a nickel-chromium alloy resistance wire (model Cr20Ni80) with a resistance value of 8Ω. It is distributed in a ring-shaped multi-layer on the outer wall of the heat conducting plate 4, with a spacing of 10mm between each layer. The power is 18W when the working voltage is 12V. The heating temperature is adjusted to 35℃±1℃ by the PID controller (Kp=0.6, Ti=15s). The above-mentioned temperature sensor 30 and humidity sensor 31 are existing technologies and will not be elaborated on here.

[0059] The embodiments of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
