Description

Technical Field

[0001] The present invention relates to the technical field of intelligent oxygen therapy, and in particular to an intelligent oxygen therapy system. Background Art

[0002] During oxygen therapy, oxygen must be humidified to a suitable humidity before it can be inhaled by the patient. At the same time, the flow rate of oxygen inhaled by the patient every day and the duration of oxygen therapy are limited by existing oxygen therapy equipment and cannot be effectively controlled, resulting in low efficiency of oxygen therapy. Moreover, in the existing oxygen humidification process, the humidification water is seriously contaminated with pathogenic bacteria, increasing the risk of secondary infection for patients. At the same time, because the central oxygen production equipment and pipelines are exposed to normal temperature, especially in winter or northern regions with very low temperatures, the temperature of the humidified oxygen is often very low, resulting in low patient compliance with oxygen therapy.

[0003] The intelligent oxygen therapy system of the related art includes an air intake unit, a humidification unit, an air outlet unit and a biological isolation unit. The air intake unit and the air outlet unit respectively include pipeline devices for conveying gas, and the air intake unit, the humidification unit, the air outlet unit and the biological isolation unit are connected to the air in sequence; the air intake unit is connected to the central oxygen supply system, and the humidified oxygen generated by the central oxygen supply system enters the humidification unit through the air intake unit, and becomes humidified oxygen after contacting the humidification water of the humidification unit, and finally is delivered to the user through the pipeline devices of the air outlet unit and the biological isolation unit.

[0004] However, the pipeline device of the air inlet unit and the air outlet unit is difficult to disassemble, clean and disinfect due to its small aperture, and it is very easy to store bacteria, thereby further contaminating the humidification bottle and other parts through the airflow. The pollution of the humidification water in use cannot be ignored. According to statistics, its contamination rate reaches 78.9%-93.9%. It is necessary to disinfect the humidification water, the oxygen to be humidified and the humidified oxygen in the humidification bottle, and the traditional chemical disinfection method will produce chemical residues, which is obviously not suitable for disinfecting medical oxygen that directly enters the respiratory tract. At the same time, during oxygen inhalation in winter or in cold weather areas, the temperature of the oxygen inhaled by the patient is too low because the oxygen production equipment and the oxygen supply pipeline are in a low temperature environment; resulting in a poor oxygen inhalation experience for the patient, and even low temperature is not conducive to the recovery of some patients.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Please refer to the attached Figure 1-Figure 3 As shown, an embodiment of the present invention provides an intelligent oxygen therapy system 100, including a central oxygen supply interface 1, a shell 2, an air outlet interface 3 and an atomization pipeline interface 4, wherein the central oxygen supply interface 1 is connected to one side of the shell 2 for connecting to an external central oxygen supply system, and the air outlet interface 3 and the atomization pipeline interface 4 are connected to the other side of the shell 2 and are arranged at intervals 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 control and disinfection unit 7 arranged in the shell 2. Oxygen is delivered to the central oxygen supply interface 1 through the external central oxygen supply system, and oxygen is 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, temperature control and secondary disinfection output are performed by the temperature control and disinfection unit 7, which has good comfort and high safety. Among them, the air outlet interface 3 is the nasal oxygen tube air outlet interface 3, and the atomization pipeline interface 4 is the nasal oxygen tube atomization pipeline interface, which prevents the possibility of pathogenic microorganisms from nasal oxygen tubes tracing back to the oxygen therapy equipment, and has high safety.

[0028] The air inlet end of the air inlet unit 5 is connected to the central oxygen supply interface 1, and the air outlet end of the air inlet unit 5 outputs oxygen to the air inlet end of the disinfection and heating unit 6 and the atomization pipeline interface 4 respectively, and the atomization pipeline interface 4 is used to output to the patient's nose. It is convenient for the patient to inhale oxygen. The disinfection and heating unit 6 heats the oxygen and performs physical disinfection before outputting it to the temperature control disinfection unit 7, and the temperature control 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 is used to humidify the oxygen output from the outlet of the air inlet unit 5, the heating unit 62 is used to heat the humidification unit 61, and the disinfection unit 63 is used to sterilize and disinfect the oxygen. During the oxygen therapy of the intelligent oxygen therapy system 100, the oxygen inhaled by the patient is clean and has no risk of secondary infection, thereby improving the safety of the patient's oxygen therapy; secondly, during the oxygen therapy, regardless of changes in external weather conditions or the influence of regional conditions, the inhaled oxygen is warm and moist, thereby improving the patient's compliance and comfort with oxygen therapy.

[0030] In this embodiment, the humidification unit 61 includes a transparent box body 611 fixed in the shell 2 for containing humidification water, a transparent partition plate 8 fixed on the inner circumference of the box body 611 and spaced from the bottom of the box body 611 to form an air guide channel 17, and a plurality of air outlet holes 612 running through the bottom of the box body 611, each of the air outlet holes 612 is respectively connected to a one-way valve (not shown in the figure); so that oxygen can only be input into the box body 611 through the one-way valve; the box body 611 is provided with a first opening 12 connected to the air guide channel 17, the first opening 12 serves as the air inlet end of the disinfection and heating unit 6, and the air outlet end of the air inlet unit 5 is connected to the first opening 12; the box body 611 is also provided with a second opening 18 located on one side of the top of the box body 611, the second opening 18 serves as the air outlet end of the disinfection and heating unit 6, and the second opening 18 is connected to the temperature control disinfection unit 7 through a second pipe 11. The box body 611 and the transparent partition 8 are made of quartz glass material or cyclic block copolymer.

[0031] In this embodiment, the disinfection unit 63 includes a circuit board 632 fixed in the housing 2 and a plurality of first ultraviolet light sources 631 mounted on the circuit board 632, and the ultraviolet light emitted by the plurality of first ultraviolet light sources 631 is irradiated toward the box 611. The humidified water in the box 611 is sterilized by ultraviolet light through the first ultraviolet light sources 631, so that the humidified water reaches the drinking water standard, thereby avoiding infection by pathogenic microorganisms during oxygen therapy.

[0032] Wherein, the quartz glass is used to transmit short-wave ultraviolet rays (UVC), and the UVC band is the 280nm-190nm band, that is, the short-wave ultraviolet rays in the UVC band have a good sterilization effect. The first ultraviolet light source 631 is an LED ultraviolet light with a wavelength of 275nm and a power of 40nW, which is excellent for humidification and water disinfection. Ultraviolet sterilization is the most effective in destroying the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in bacteria and viruses when the ultraviolet wavelength is in the range of 240 to 280nm, causing growth cell death and (or) regenerative cell death, achieving the effect of sterilization and disinfection. The first ultraviolet light source 631 has a wavelength of 275nm, which has a better sterilization effect.

[0033] Specifically, take a fresh E. coli slant cultured at 37°C for 18h-24h, wash the bacterial moss with saline, mix well, and then dilute appropriately with saline to prepare a test E. coli suspension. Set up a test group, and determine the bactericidal effect of the first ultraviolet light source 631 on E. coli through quartz glass within 15min, 30min and 45min. Set up a positive control group, and count the live bacteria culture with unsterilized test bacteria contaminated water samples; set up a negative control group, and culture with unused culture medium from the same batch used in the test to observe whether there is bacterial growth.

[0034] The water sterilization operation process is as follows:

[0035] 1) Preparation of water sample contaminated by test bacteria: Add Escherichia coli suspension prepared with physiological saline into dechlorinated tap water or distilled water to make the bacterial count reach 5×10 5 CFU / 100ml~5×10 5 CFU / 100ml.

[0036] 2) Take 2 test bacteria contaminated water samples and count the viable E. coli according to the following method (positive control group). The culture count of viable bacteria in the test bacteria contaminated water samples is as follows;

[0037] Boil the fiber filter in distilled water for 3 times, 5 minutes each time, and wash it 2-3 times with new distilled water after each boiling to remove the residual solvent.

[0038] Sterilize the filter with pressure steam (121℃, 20min), or with alcohol flame. Use sterile tweezers to pick up the edge of the sterile filter membrane, put the rough surface upward, and stick it on the filter bed of the sterilized filter, and fix the filter securely. Take a certain amount of water sample to be tested (diluted or undiluted) and inject it into the filter, cover it, open the air extraction valve, and filter it under negative pressure of 0.05Mpa.

[0039] After the water sample is filtered, vacuum for about 5 seconds, close the filter valve, and remove the filter. Use sterile tweezers to pick up the edge of the filter membrane and place it on the fuchsin sodium sulfite agar medium plate, with the filter membrane intercepting bacteria facing up. The filter membrane should be completely close to the agar medium, and no bubbles should be left in it. Then turn the plate upside down and place it in a 37℃ constant temperature incubator for 22h to 24h.

[0040] Observation results and counting: Count the dark purple Escherichia coli colonies with a metallic luster growing on the filter membrane, and calculate the number of Escherichia coli contained in the contaminated water sample (CFU / 100ml).

[0041] 3) Use air pressure method to disinfect. Connect high pressure (2kg / cm 2 ~3kg / cm 2) Air source, pressure-resistant water sample storage tank (3 samples kg / cm 2 ~5kg / cm 2 ), flow meter and drinking water sterilizer. Then pass the water sample with the test bacteria through the sterilizer, place the sterilized water sample for a specified time, and then take it out and add it to the sterilized triangular bottle containing the neutralizer and mix it. Take 100ml, 10ml and 1ml of the neutralized water sample respectively, and count the live bacteria of Escherichia coli according to the method shown above.

[0042] 4) Place two plates of the same batch of culture medium for the test that were not inoculated with E. coli in an incubator (negative control group).

[0043] 5) The experiment was repeated 3 times.

[0044] In summary, the test was repeated three times under the constant temperature control of 20℃±1℃, and the E. coli was reduced to 0 / 100ml after the first ultraviolet light source 631 acted through the quartz glass for 15 minutes. The results are shown in Table 1 below;

[0045] Table 1-The killing effect of the first ultraviolet light source on Escherichia coli

[0046]

[0047]

[0048] In Table 1 above, the killing effect of Escherichia coli by the first ultraviolet light source 631 meets the requirements of drinking water disinfection. Therefore, the humidified water in the box 611 is sterilized by ultraviolet light by the first ultraviolet light source 631, so that the humidified water reaches the drinking water standard and avoids infection by pathogenic microorganisms during oxygen therapy.

[0049] In the present invention, the housing can also be made of CBC material. CBC material is generally called a new type of olefin copolymer of cyclic block copolymer (CBC for short). This polymer material is obtained by copolymerization of vinyl aromatic hydrocarbons and conjugated olefins, and then undergoing a complete hydrogenation process with a special high-efficiency catalyst. CBC material is suitable for ultraviolet humidification disinfection due to its extreme cleanliness, ultra-high transparency, high ultraviolet transmittance and other characteristics. By repeating the above experiment, a consistent sterilization effect can be achieved.

[0050] In this embodiment, the intelligent oxygen therapy system 100 further includes an electronic valve 9, the air inlet end of the electronic valve 9 is connected to the air outlet end of the air inlet unit 5, and the other end of the electronic valve 9 is connected to the air 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, the operating software (only medical staff can operate) is used to control the oxygen flow rate and duration, thereby ensuring that the patient can strictly follow the doctor's instructions to implement the oxygen therapy plan during the oxygen inhalation process.

[0051] Preferably, the intelligent oxygen therapy system 100 further includes an ultrasonic cleaning device, which is disposed in the box 611 and is used to automatically clean the humidification water in the box 611. The nursing staff can automatically and regularly clean the humidification box 611 according to the machine program to ensure that the humidification meets the disinfection specification and is free of other impurities, thereby ensuring the safety of the patient's oxygen therapy.

[0052] In this embodiment, the plurality of air outlet holes 612 are arranged in an array so that the oxygen in the box 611 is discharged evenly and the humidification effect is better.

[0053] In this embodiment, the heating unit 62 is a heating plate installed in the box 611, and the heating plate is fixed to the side wall of the box 611. The heating plate is connected to an external circuit for power supply to heat the humidification water in the box 611, so that the temperature of oxygen is increased to a suitable temperature for users when humidified, and the comfort is high. The oxygen is heated to a temperature suitable for the body, optimizing the patient's experience of oxygen therapy.

[0054] In this embodiment, the disinfection unit 63 is fixed in the housing 2 and is located at the bottom and / or side wall of the humidification unit 61 .

[0055] In this embodiment, the temperature control and disinfection unit 7 includes a container 16, a second ultraviolet light source (not shown in the figure) and a heating film (not shown in the figure) arranged on one side of the container 16. The side of the container 16 away from the disinfection and heating unit 6 forms an air inlet end and an air outlet end of the temperature control and disinfection unit 7. The air inlet end of the temperature control and disinfection unit 7 is connected to the second opening, and the air outlet end of the temperature control and disinfection unit 7 is connected to the air outlet interface. The ultraviolet light of the second ultraviolet light source is irradiated toward the air outlet end of the temperature control and disinfection unit 7 for secondary sterilization. The heating film is used to perform secondary heating and temperature control on the oxygen in the container 16.

[0056] Among them, the heating film and the second ultraviolet light source are both connected to an external circuit to realize the light-emitting and heat-generating functions, thereby performing temperature control and secondary disinfection and sterilization on the oxygen passing through the container 16. Optionally, the container 16 and the gas outlet are both made of quartz glass material or cyclic block copolymer. There is no blocking object between the second ultraviolet light source and the container 16 and the gas outlet, so that the container 16 and the gas outlet can be directly irradiated by the second ultraviolet light source, so that the oxygen passing through the gas outlet can be sterilized by the second ultraviolet light source, thereby achieving the effect of secondary sterilization and disinfection of oxygen.

[0057] Optionally, the first ultraviolet light source 611 and the second ultraviolet light source are both LED ultraviolet light sources. The disinfection unit 63 and the temperature control disinfection unit 7 not only use LED ultraviolet light sources for disinfection, but also other disinfection methods, which will not be described here.

[0058] In this embodiment, the atomization pipeline interface 4 is connected to the second gas outlet end of the electronic valve 9 through a third pipeline 13. Biological isolation technology is used at the oxygen outlet to prevent pathogenic microorganisms in the nasal oxygen tube 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 interface 15 that runs through one side of the housing 2; the display screen 14 is used to display the parameters of the oxygen, and the oxygen interface 15 is used to connect medical gas. The parameters of oxygen include temperature, humidity, sterilization amount, flow rate, etc.

[0060] The working principle of the present invention is as follows:

[0061] The first gas passage: After the intelligent oxygen therapy system 100 is connected to the central oxygen supply, oxygen enters the electronic valve 9, and the flow rate of oxygen inhaled by the patient is set by the electronic valve 9. The oxygen passes through the disinfection and heating unit 6, and then in this space, the oxygen passes through the humidified water, and the humidified water is heated to an appropriate temperature through the heating membrane, which serves the purpose of heating the oxygen. When 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 so that the humidified water reaches the drinking water standard. After the oxygen comes out of the disinfection and heating unit 6, it enters the secondary temperature control disinfection unit 7. In this space, the heating guide wire is used to heat the oxygen for the second time to remove excess water and reduce the generation of condensed water. At the same time, the second ultraviolet light source is used to irradiate the outlet at the outlet of the nasal oxygen tube to block the reflux of pathogenic microorganisms in the nasal oxygen tube, and the oxygen is finally input to the patient through the nasal oxygen tube.

[0062] The second gas pathway: After the intelligent oxygen therapy system 100 is connected to the central oxygen supply, oxygen passes through the electronic valve 9, and the flow rate of oxygen inhaled by the patient is set by the electronic valve 9. The oxygen is transmitted to the atomization pipeline interface 4 of the nasal oxygen tube through the third pipeline 13, and the atomization pipeline interface 4 is directly connected to an external atomization bottle to provide atomization therapy for the patient.

[0063] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
