Abstract
Description
Technical Field
[0001] This utility model relates to the field of intelligent oxygen therapy technology, and in particular to an intelligent oxygen therapy system. Background Technology
[0002] During oxygen therapy, oxygen must be humidified to a suitable level before being inhaled by the patient. However, the daily oxygen flow rate and duration of oxygen therapy are limited by existing equipment, making effective control difficult and resulting in low efficiency. Furthermore, the humidification water is often contaminated with pathogens, increasing the risk of secondary infections. Additionally, because central oxygen generation equipment and piping are exposed to ambient temperatures, especially in cold winters or northern regions, the humidified oxygen is often very cold, leading to low patient compliance with oxygen therapy.
[0003] The intelligent oxygen therapy system based on related technologies includes an air intake unit, a humidification unit, an air outlet unit, and a bio-isolation unit. The air intake unit and air outlet unit each include piping devices for gas delivery. The air intake unit, humidification unit, air outlet unit, and bio-isolation unit are sequentially connected by air. The air intake unit is connected to a central oxygen supply system. The oxygen to be humidified generated by the central oxygen supply system enters the humidification unit through the air intake unit, comes into contact with the humidifying water in the humidification unit, and becomes humidified oxygen. Finally, it is delivered to the user through the piping devices of the air outlet unit and the bio-isolation unit.
[0004] However, the small orifice size of the piping in the air intake and exhaust units makes them difficult to disassemble, clean, and disinfect, easily leading to bacterial accumulation and further contamination of the humidification bottle and other parts via airflow. The contamination of the humidification water in use is even more significant, with a statistically observed contamination rate of 78.9%-93.9%. Disinfecting the humidification water, oxygen to be humidified, and humidified oxygen in the humidification bottle is essential. Traditional chemical disinfection methods leave chemical residues, which are clearly unsuitable for disinfecting medical oxygen that enters the respiratory tract directly. Furthermore, during oxygen therapy in winter or cold regions, the oxygen generating equipment and delivery pipelines are in a low-temperature environment, resulting in excessively low oxygen temperatures for patients, leading to a poor oxygen therapy experience and even hindering recovery for some patients. Additionally, current technologies cannot adjust the oxygen therapy gas to a suitable temperature for the human body, resulting in poor patient compliance and experience. Utility Model Content

Detailed Implementation
[0026] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0027] Please see the appendix Figures 1-3 As shown, this utility model embodiment provides an intelligent oxygen therapy system 100, including a central oxygen supply interface 1, a housing 2, an air outlet interface 3, and a nebulizer interface 4. The central oxygen supply interface 1 is connected to one side of the housing 2 for connecting to an external central oxygen supply system. The air outlet interface 3 and the nebulizer interface 4 are connected to the other side of the housing 2 and are spaced apart from each other. The intelligent oxygen therapy system 100 also includes an air intake unit 5, a disinfection and heating unit 6, and a temperature-controlled disinfection unit 7 disposed within the housing 2. Oxygen is delivered to the central oxygen supply interface 1 through the external central oxygen supply system, and then delivered to the disinfection and heating unit 6 through the air intake unit 5. After humidification and heating disinfection by the disinfection and heating unit 6, the temperature is controlled and secondary disinfection is performed by the temperature-controlled disinfection unit 7, resulting in good comfort and high safety. The air outlet interface 3 is the nasal cannula air outlet interface 3, and the nebulizer interface 4 is the nasal cannula nebulizer interface, preventing pathogenic microorganisms from potentially flowing back into the oxygen therapy device from the nasal cannula, thus ensuring high safety.
[0028] The air intake end of the air intake unit 5 is connected to the central oxygen supply interface 1. The air outlet end of the air intake unit 5 outputs oxygen to the air intake end of the disinfection and heating unit 6 and the nebulization pipeline interface 4, respectively. The nebulization pipeline interface 4 is used to output oxygen to the patient's nose for convenient oxygen inhalation. The disinfection and heating unit 6 heats and physically disinfects the oxygen before outputting it to the temperature-controlled disinfection unit 7. The temperature-controlled disinfection unit 7 performs secondary temperature control and physical disinfection on the input oxygen before outputting it to the air outlet interface 3.
[0029] The disinfection and heating unit 6 includes a humidification unit 61, a heating unit 62, and a disinfection unit 63. The humidification unit 61 humidifies the oxygen output from the outlet of the air intake unit 5, the heating unit 62 heats the humidification unit 61, and the disinfection unit 63 sterilizes the oxygen. This ensures that the oxygen inhaled by the patient during oxygen therapy in the intelligent oxygen therapy system 100 is clean and free from secondary infection risk, improving the safety of oxygen therapy. Furthermore, regardless of changes in external weather conditions or geographical location, the inhaled oxygen is warm and humid, improving patient compliance and comfort.
[0030] In this embodiment, the humidification unit 61 includes a transparent box 611 fixed inside the housing 2 for holding humidification water, a transparent partition 8 fixed to the inner periphery of the box 611 and spaced apart from the bottom of the box 611 to form an air guide channel 17, and a plurality of air outlets 612 penetrating the bottom of the box 611. Each air outlet 612 is connected to a one-way valve (not shown in the figure), so that oxygen can only be input into the box 611 through the one-way valve. The box 611 has a first opening 12 communicating with the air guide channel 17. The first opening 12 serves as the air inlet of the disinfection heating unit 6, and the air outlet of the air inlet unit 5 is connected to the first opening 12. The box 611 also has a second opening 18 located on the top side of the box 611. The second opening 18 serves as the air outlet of the disinfection heating unit 6, and the second opening 18 is connected to the temperature control disinfection unit 7 through a second pipe 11. The box 611 and the transparent partition 8 are made of quartz glass or cyclic block copolymer.
[0031] In this embodiment, the disinfection unit 63 includes a circuit board 632 fixed inside the housing 2 and a plurality of first ultraviolet light sources 631 mounted on the circuit board 632. The ultraviolet light emitted by the plurality of first ultraviolet light sources 631 is directed towards the housing 611. The first ultraviolet light sources 631 perform ultraviolet sterilization treatment on the humidified water inside the housing 611, so that the humidified water meets drinking water standards and avoids pathogenic microorganism infection during oxygen therapy.
[0032] The quartz glass is used to transmit short-wave ultraviolet (UVC) light, specifically the 280nm-190nm band, which provides excellent sterilization. The first ultraviolet light source 631 is an LED ultraviolet light source with a wavelength of 275nm and a power of 40nW, which is highly effective for humidifying water disinfection. Ultraviolet sterilization utilizes ultraviolet light with wavelengths in the 240-280nm range to effectively destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in bacteria and viruses, causing cell death and / or regenerative cell death, thus achieving sterilization and disinfection. The first ultraviolet light source 631, with a wavelength of 275nm, provides even better sterilization.
[0033] Specifically, fresh *E. coli* slant cultured at 37℃ for 18-24 hours was used. The bacterial growth was washed off with physiological saline, mixed thoroughly, and then appropriately diluted with physiological saline to prepare a test *E. coli* suspension. Experimental groups were set up, and the bactericidal effect of the first ultraviolet light source 631 transmitted through quartz glass on *E. coli* was measured at 15 min, 30 min, and 45 min. A positive control group was set up, using unsterilized water samples contaminated with the test bacteria for viable bacterial count; a negative control group was set up, using unused culture medium from the same batch used in the experiment for culture, and the presence or absence of bacterial growth was observed.
[0034] The water sterilization operation procedure is as follows:
[0035] 1) Preparation of water samples contaminated with test bacteria: Add the E. coli suspension prepared with physiological saline to dechlorinated tap water or distilled water to achieve a bacterial count of 5 × 10⁻⁶. 5 CFU / 100ml~5×10 5 CFU / 100ml.
[0036] 2) Take two water samples contaminated with the test bacteria and count the viable Escherichia coli (positive control group) according to the method shown below. The culture count of viable bacteria in the water samples contaminated with the test bacteria is as follows;
[0037] Sterilize the fiber filter membrane by boiling it in distilled water three times, for 5 minutes each time. After each boiling, wash it 2-3 times with fresh distilled water to remove any residual solvent.
[0038] Sterilize the filter using pressurized steam (121℃, 20 min) or by alcohol flame sterilization. Using sterile forceps, grasp the edge of the sterile filter membrane, rough side up, and place it on the filter bed of the sterilized filter, securing it firmly. Inject a certain amount of the water sample to be tested (diluted or undiluted) into the filter, cap it, open the suction valve, and filter under negative pressure of 0.05 MPa.
[0039] After filtering the water sample, aspirate for about 5 seconds, close the filter valve, and remove the filter. Use sterile forceps to pick up the edge of the filter membrane and place it on a fuchsin sodium sulfite agar plate, with the bacterial-bearing side of the filter membrane facing upwards. The filter membrane should be in complete contact with the agar medium, without any air bubbles. Then, invert the plate and incubate it in a 37°C incubator for 22-24 hours.
[0040] Observation results and counting: The number of E. coli colonies with a metallic sheen and a dark purple color growing on the filter membrane was counted, and the number of E. coli in the contaminated water sample (CFU / 100ml) was calculated.
[0041] 3) Disinfection is performed using pneumatic pressure. Connect the high-pressure system (2 kg / cm²) as required. 2 ~3kg / cm 2Gas source, pressure-resistant water sample storage container (3 samples kg / cm³) 2 ~5kg / cm 2 The process involves using a flow meter and a water sterilizer. The water sample containing the test bacteria is then passed through the sterilizer. After sterilization, the sample is left to stand for a specified time, and then each sample is added to a sterilized Erlenmeyer flask containing a neutralizing agent and mixed thoroughly. Two portions each of 100ml, 10ml, and 1ml of the neutralized water sample are taken and used to count the viable E. coli bacteria as described above.
[0042] 4) Place two plates of the same batch of culture medium used for the test that were not inoculated with E. coli in an incubator for incubation (negative control group).
[0043] 5) The experiment was repeated 3 times.
[0044] In summary, by repeating the experiment three times under constant temperature control of 20℃±1℃, and by exposing the first ultraviolet light source 631 through quartz glass for 15 minutes, the E. coli count decreased to 0 / 100ml. The results are shown in Table 1 below.
[0045] Table 1 - Killing effect of the first ultraviolet light source on Escherichia coli
[0046]
[0047]
[0048] Table 1 above shows the killing effect of the first ultraviolet light source 631 on Escherichia coli, which meets the requirements for drinking water disinfection. Therefore, by using the first ultraviolet light source 631 to perform ultraviolet sterilization treatment on the humidified water inside the chamber 611, the humidified water meets drinking water standards, thus avoiding pathogenic microbial infection during oxygen therapy.
[0049] In this invention, the housing can also be made of CBC material. CBC material is generally referred to as a novel olefin copolymer, a cyclic block copolymer (CBC). This polymer material is produced through the copolymerization of vinyl aromatics and conjugated olefins, followed by a complete hydrogenation process using a special high-efficiency catalyst. CBC material, with its extreme cleanliness, ultra-high transparency, and high ultraviolet transmittance, is suitable for ultraviolet humidification disinfection. By repeating the above experiments, a consistent sterilization effect can be achieved.
[0050] In this embodiment, the intelligent oxygen therapy system 100 further includes an electronic valve 9. The inlet end of the electronic valve 9 is connected to the outlet end of the inlet unit 5, and the other end of the electronic valve 9 is connected to the inlet end of the disinfection and heating unit 6 through a first pipe 10. By using the electronic valve 9 to control the flow rate and using operating software (operable only by medical personnel) to control the oxygen flow rate and duration, it is ensured that patients can strictly follow the doctor's orders to perform the oxygen therapy plan during oxygen inhalation.
[0051] More preferably, the intelligent oxygen therapy system 100 also includes an ultrasonic cleaning device, which is installed inside the housing 611 and used to automatically clean the humidification water inside the housing 611. By having nursing staff perform automatic periodic cleaning of the humidification housing 611 according to the machine's program, the humidification process ensures that it meets disinfection standards and is free of other impurities, thereby guaranteeing the safety of oxygen therapy for patients.
[0052] In this embodiment, the multiple air outlets 612 are arranged in an array. This ensures uniform oxygen discharge within the housing 611 and improves humidification.
[0053] In this embodiment, the heating unit 62 is a heating plate installed inside the housing 611, and the heating plate is attached and fixed to the side wall of the housing 611. After being powered by an external circuit, the heating plate heats the humidifying water inside the housing 611, thereby increasing the temperature of the oxygen as it passes through the humidifier to a level suitable for the user, resulting in high comfort. Heating the oxygen to a comfortable temperature optimizes the patient's experience during oxygen therapy.
[0054] In this embodiment, the disinfection unit 63 is fixed inside the housing 2 and located at the bottom and / or side wall of the humidification unit 61.
[0055] In this embodiment, the temperature-controlled disinfection unit 7 includes a container 16, a second ultraviolet light source (not shown in the figure) disposed on one side of the container 16, and a heating film (not shown in the figure). The side of the container 16 away from the disinfection heating unit 6 forms the air inlet and air outlet of the temperature-controlled disinfection unit 7. The air inlet of the temperature-controlled disinfection unit 7 is connected to the second opening, and the air outlet of the temperature-controlled disinfection unit 7 is connected to the air outlet interface. The ultraviolet light from the second ultraviolet light source irradiates the air outlet of the temperature-controlled disinfection unit 7 for secondary sterilization. The heating film is used to perform secondary heating and temperature control of the oxygen in the container 16.
[0056] The heating film and the second ultraviolet light source are both connected to an external circuit to achieve light emission and heat generation, thereby controlling the temperature and performing secondary sterilization on the oxygen passing through container 16. Optionally, both container 16 and the outlet end are made of quartz glass or cyclic block copolymer. There are no obstructions between the second ultraviolet light source and container 16 and the outlet end, allowing the second ultraviolet light source to directly irradiate container 16 and the outlet end, enabling the oxygen passing through the outlet end to be sterilized by the second ultraviolet light source, thus achieving the effect of secondary sterilization of oxygen.
[0057] Optionally, both the first ultraviolet light source 611 and the second ultraviolet light source are LED ultraviolet light sources. The disinfection unit 63 and the temperature-controlled disinfection unit 7 may use other disinfection methods besides LED ultraviolet light sources, which will not be described here.
[0058] In this embodiment, the nebulizer tube interface 4 and the second outlet of the electronic valve 9 are connected via a third pipe 13. Bio-isolation technology is employed at the oxygen outlet to prevent pathogenic microorganisms from the nasal cannula from flowing back and contaminating the oxygen therapy equipment.
[0059] In this embodiment, the intelligent oxygen therapy system 100 further includes a display screen 14 and an oxygen finger interface 15 penetrating one side of the housing 2; the display screen 14 is used to display the parameters of the oxygen, and the oxygen finger interface 15 is used to connect to medical gas. The oxygen parameters include temperature, humidity, sterilization rate, and flow rate, etc.
[0060] The working principle of this utility model is as follows:
[0061] The first gas pathway: After the intelligent oxygen therapy system 100 is connected to the central oxygen supply, oxygen enters the electronic valve 9, which sets the flow rate for the patient's inhalation. The oxygen then passes through the disinfection and heating unit 6. Within this space, the oxygen passes through humidified water, which is heated to an appropriate temperature by a heating membrane, thus heating the oxygen. While the oxygen passes through the heated humidified water, the first ultraviolet light source 631 in the disinfection and heating unit 6 disinfects the humidified water, ensuring it meets drinking water standards. After exiting the disinfection and heating unit 6, the oxygen enters the secondary temperature-controlled disinfection unit 7. In this space, a heating guide wire reheats the oxygen, removing excess moisture and reducing condensation. Simultaneously, a second ultraviolet light source irradiates the nasal cannula outlet to prevent the backflow of pathogenic microorganisms. Finally, the oxygen is delivered to the patient through the nasal cannula.
[0062] The second gas pathway: After the intelligent oxygen therapy system 100 is connected to the central oxygen supply, the oxygen passes through the electronic valve 9. The oxygen flow rate is set by the electronic valve 9 and then transmitted through the third pipe 13 to the nebulization tube interface 4 of the nasal oxygen tube. The nebulization tube interface 4 is directly connected to an external nebulizer bottle to provide nebulization treatment to the patient.
[0063] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.
