Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a single gas source gas path system and an integrated oxygen therapy and saline therapy device. Background Technology

[0002] Rock salt aerosol therapy (salt aerosol therapy) is a non-drug therapy that uses salt aerosols to treat respiratory diseases. It increases the concentration of ions in the respiratory tract, changes the osmotic pressure of mucus, improves the rheology of respiratory mucus, activates the innate immunity of lung tissue, and enhances the activity of pulmonary macrophages. This achieves the goals of antibacterial and anti-inflammatory effects, relieving edema, enhancing clearance and expectoration, and boosting immunity and resistance, thereby preventing, improving, and treating respiratory diseases.

[0003] When a patient with respiratory disease has impaired lung capacity and oxygenation, the primary need is to treat the hypoxia by administering oxygen therapy to improve the patient's partial pressure of oxygen and blood oxygen saturation. For patients requiring oxygen therapy, especially critically ill patients needing oxygen via a breathing mask, current oxygen therapy and saline therapy equipment are separate devices; there is no equipment that simultaneously supports both functions. Oxygen and saline therapy cannot be performed concurrently, requiring repeated switching, which is cumbersome, leads to a poor patient experience, and fails to achieve the desired therapeutic effect. Furthermore, oxygen therapy and saline therapy require purchasing two sets of equipment and using two separate operating methods, increasing treatment costs, time costs, and operational complexity. Summary of the Invention

[0004] To address the issues of saline therapy, the inability to use saline therapy simultaneously, high costs, and operational difficulties, this invention provides a pneumatic system and an integrated oxygen and saline therapy device. By designing a single pneumatic system, users can simultaneously perform oxygen and saline therapy, reducing operating costs and simplifying operation.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows: a single gas source gas path system, comprising a gas source, an oxygen production branch, a salt aerosol branch, and a mixing section; The gas source is connected to the oxygen generation branch and the salt aerosol branch respectively, providing compressed air to the oxygen generation branch and the salt aerosol branch; The oxygen generation branch separates nitrogen and oxygen in the compressed air supplied by the gas source to provide oxygen to the user. The salt aerosol branch is used to generate dry salt aerosols to provide users with salt aerosol therapy. The mixing section connects the oxygen generation branch and the saline aerosol branch, and is used to mix the oxygen generated by the oxygen generation branch with the saline aerosol generated by the saline aerosol branch for the user to inhale for treatment.

[0006] Furthermore, the air source is an air compressor, and the air compressor is equipped with a filter at its air inlet to filter the air entering the air compressor and provide clean air for the oxygen generation branch and the salt aerosol branch.

[0007] Furthermore, the air compressor outlet is connected to a cooling device to cool the compressed air output by the air compressor, and the cooled compressed air is input into the oxygen generation branch and the salt aerosol branch respectively.

[0008] Specifically, the cooling device is one of a transducer, a condenser, or a heat dissipation pipeline.

[0009] When the air compressor outputs compressed air, it generates heat. The compressed air needs to be cooled down by a cooling device before it is introduced into the oxygen generating unit to avoid the compressed air entering the oxygen generating unit being too hot and reducing the oxygen generating efficiency.

[0010] One technical solution is that the cooling device uses a condenser, which can condense and discharge the moisture in the compressed air, thereby drying the compressed air. On the one hand, this can improve the oxygen production efficiency of the oxygen generation unit; on the other hand, the dry air is beneficial for the drying of salt aerosols.

[0011] Another technical solution is that the cooling device is a transducer, the air inlet of which is connected to an air compressor, and the air outlet is connected to an oxygen generation branch and a salt aerosol branch respectively; the transducer is also connected to a mixing section, and while having the function of cooling compressed air as a condenser, it can also collect the heat of compressed air and conduct it to the mixing section to heat the gas in the mixing section. Alternatively, the transducer's inlet end is connected to an air compressor, and its outlet end is connected to an oxygen generation branch and a salt aerosol branch, respectively. The transducer is also connected to an evaporator in the salt aerosol branch. While acting as a condenser to cool the compressed air, it can also collect the heat from the compressed air and conduct it to the evaporator to provide heat for the evaporator to dry the liquid mist.

[0012] In another technical solution, the cooling device can also use heat dissipation pipes to reduce the temperature of the compressed air.

[0013] Furthermore, the oxygen generation branch includes an oxygen generation unit, an oxygen storage section for storing oxygen, and a first pressure regulating component for adjusting the oxygen output pressure; one end of the oxygen generation unit is connected to a cooling device, and the other end is connected to the oxygen storage section and the first pressure regulating component in sequence through a ventilation pipe before being introduced into the mixing section.

[0014] Specifically, the oxygen storage unit is an oxygen storage tank, a gas storage tank, or a gas collection chamber, or other devices used for storing oxygen.

[0015] Furthermore, a first flow sensor, an oxygen concentration sensor, and a first one-way valve are provided between the first pressure regulating component and the mixing section, and the oxygen generating unit is at least one molecular sieve or nitrogen-oxygen separation membrane.

[0016] The first one-way valve allows oxygen to flow only from the oxygen generating unit to the mixing section, and not in the reverse direction; the first flow sensor is used to detect the oxygen flow rate after pressure regulation; and the oxygen concentration sensor is used to detect the oxygen concentration before mixing with the salt aerosol.

[0017] Specifically, when the oxygen generating unit consists of two or more molecular sieves, an electromagnetic reversing valve is installed between the cooling device and the molecular sieves. Taking two molecular sieves as an example, when the nitrogen adsorbed by the first molecular sieve becomes saturated, the reversing valve is used to switch the direction so that the second molecular sieve can start working. At the same time, the first molecular sieve discharges the adsorbed nitrogen to restore its adsorption function. When the nitrogen adsorbed by the second molecular sieve becomes saturated, the reversing valve is used to switch the direction so that the first molecular sieve can start working. At the same time, the second molecular sieve discharges the adsorbed nitrogen to restore its adsorption function. The two molecular sieves alternate in sequence, so that oxygen can be generated continuously.

[0018] Furthermore, the salt aerosol branch includes a salt particle assembly, a second pressure regulating assembly and a second one-way valve are provided between the salt particle assembly and the cooling device, and a third one-way valve is provided between the salt particle assembly and the mixing section.

[0019] The second check valve only allows compressed air to flow from the air compressor to the salt aerosol branch, and does not allow salt aerosol generated in the salt aerosol branch to flow back into the air compressor.

[0020] The third one-way valve only allows salt aerosol to flow from the salt microparticle assembly to the mixing section, and does not allow oxygen to flow back into the salt microparticle assembly.

[0021] Furthermore, a second flow sensor and a concentration sensor are provided between the salt particle assembly and the third one-way valve.

[0022] The second flow sensor is used to detect the flow rate of salt aerosol generated by the salt aerosol branch, and the concentration sensor is used to detect the concentration of salt aerosol.

[0023] One technical solution is that the salt microparticle assembly is a salt box, which stores pre-made salt microparticles and is provided with an air inlet and an air outlet. The air source can blow the salt microparticles in the salt box to form a salt sol. Another technical solution is that the salt microparticle assembly is a grinding chamber, including a chamber body and grinding tools. The chamber body has an air inlet and an air outlet. The grinding tools are set inside the chamber body and can cut and grind the rock salt ingredients inside the chamber body into tiny salt particles. The air source blows out the ground salt particles to form a salt sol.

[0024] In another technical solution, the salt particle assembly comprises a salt spray generator and an evaporator. The salt spray generator atomizes the salt solution into a liquid mist of tiny droplets, the evaporator evaporates and dries the liquid mist into dry salt particles, and the gas source blows the salt particles out to form a salt aerosol.

[0025] Furthermore, one technical solution for the mixing section is as follows: the mixing section is a section of ventilation pipeline where oxygen output from the oxygen generation branch and salt aerosol output from the salt aerosol branch converge. Another technical solution for the mixing section: the mixing section is a separately designed mixing section on the ventilation pipeline; Another technical solution for the mixing section: the mixing section is the space between the breathing mask and the user's nasal cavity and / or oral cavity; Another technical solution for the mixing section: the mixing section is a relatively enclosed treatment space.

[0026] Specifically, the relatively enclosed treatment space includes an oxygen chamber, a treatment chamber, a treatment room, etc. Oxygen generated by the oxygen generation branch and salt aerosol generated by the salt aerosol branch are diffused and mixed in the treatment space, and the user inhales the mixed air in the treatment space for treatment.

[0027] Furthermore, a third flow sensor, a second oxygen concentration sensor, and a second concentration sensor are also provided between the mixing unit and the patient's inhalation end; the third flow sensor is used to detect the flow rate of the mixed gas at the user's inhalation end, the second oxygen concentration sensor is used to detect the oxygen concentration at the user's inhalation end, and the second concentration sensor is used to detect the concentration of salt aerosol at the user's inhalation end.

[0028] Furthermore, the first pressure regulating component and the second pressure regulating component are respectively a first pressure regulating valve and a second pressure regulating valve, and may also be a first stepper motor, a second stepper motor, or other devices used to regulate gas flow or pressure.

[0029] An integrated oxygen therapy and saline therapy device was also disclosed, including a power module, a control module, and the aforementioned single-source airway system, which allows users to inhale saline aerosols for saline therapy while receiving oxygen therapy, in order to treat hypoxia, respiratory diseases, promote expectoration, and relieve airway mucosal edema.

[0030] The beneficial effects of this utility model are: 1. The gas path system of this utility model combines the oxygen generation branch and the saline aerosol branch, which solves the problem that users cannot perform saline therapy at the same time when using an oxygen concentrator to inhale oxygen. This allows patients to perform saline therapy at the same time as inhaling oxygen, effectively promoting the treatment of respiratory diseases. At the same time, saline aerosol can promote patients to expectorate sputum and relieve airway mucosal edema, which has a positive effect on patients' oxygen therapy. Oxygen therapy and oxygen therapy can play a synergistic role, achieving a 1+1 greater than 2 effect. 2. The oxygen generation branch and the salt aerosol branch share a common gas source. The gas pressure and flow rate entering the salt aerosol branch are regulated by a pressure regulating component, which simplifies the equipment structure, reduces costs, and simplifies the control program. 3. When the liquid mist is dried and evaporated in the salt aerosol branch, the water vapor generated by the liquid mist is mixed with oxygen together with the salt aerosol to humidify the oxygen. There is no need to use an additional humidifier to humidify the oxygen, which improves the patient's comfort. 4. In the saline aerosol branch, after the liquid mist is dried and evaporated to form saline aerosol, the saline aerosol carries the heat from the evaporator and mixes with oxygen to heat the oxygen. There is no need to set up an additional heating component to heat the oxygen, which improves the patient's comfort. 5. By integrating the oxygen generation equipment and saline aerosol equipment into a single device through the gas path system, only one control module and power supply module are needed to simultaneously control the working parameters of oxygen therapy and saline therapy, reducing the burden on users and simplifying operation. 6. The cooling device uses a transducer to collect the heat generated by the compressor and use it to heat the gas after the oxygen and salt aerosol are mixed, eliminating the need for a separate heating component to heat the gas; or it can collect the heat generated by the compressor and use it to dry the liquid mist in the salt aerosol branch, which can reduce energy consumption.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figure 1As shown, an embodiment of a single-source gas path system includes a gas source 1, an oxygen generation branch 2, a saline aerosol branch 3, and a mixing unit 4. The gas source 1 is connected to both the oxygen generation branch 2 and the saline aerosol branch 3, providing compressed air to both branches. The oxygen generation branch 2 separates nitrogen and oxygen in the compressed air provided by the gas source to provide oxygen to the user. The saline aerosol branch 3 generates dry saline aerosol to provide saline aerosol therapy to the user. The mixing unit 4 connects the oxygen generation branch 2 and the saline aerosol branch 3, and mixes the oxygen generated by the oxygen generation branch 2 with the saline aerosol generated by the saline aerosol branch 3 for the user to inhale for therapy.

[0036] In this embodiment, the air source 1 is an air compressor. A filter is installed at the air inlet of the air compressor to filter the air entering the air compressor and provide clean air for the oxygen generation branch 2 and the salt aerosol branch 3. A cooling device is connected to the air outlet of the air compressor to cool the compressed air output by the air compressor and input the cooled compressed air into the oxygen generation branch 2 and the salt aerosol branch 3 respectively.

[0037] In some other embodiments, the gas source 1 may also be a central gas supply.

[0038] Specifically, the cooling device can be any of a transducer, condenser, or heat dissipation piping. When an air compressor outputs compressed air, it generates heat, which heats the compressed air. The temperature of the compressed air may exceed the operating temperature of the oxygen generator. Therefore, the temperature of the compressed air needs to be reduced by a cooling device before it is introduced into the oxygen generator to avoid the compressed air entering the oxygen generator being too hot, which would reduce the oxygen generation efficiency or even damage the oxygen generator.

[0039] In this embodiment, a condenser is used to cool the compressed air while condensing and discharging the moisture in the compressed air, thus drying the compressed air. The dried air can improve the oxygen production efficiency of the oxygen generation unit and the drying efficiency of the salt aerosol.

[0040] Reference Figure 1 As shown, the oxygen generation branch 2 includes an oxygen generation unit, an oxygen storage section for storing oxygen, and a first pressure regulating valve for adjusting the oxygen output pressure; one end of the oxygen generation unit is connected to the condenser, and the other end is connected to the oxygen storage section and the first pressure regulating valve in sequence through a ventilation pipeline and then to the mixing section.

[0041] It is understood that the oxygen storage unit referred to in this embodiment refers to a device for storing oxygen, and can also be a buffer tank, gas storage chamber, or other storage device that plays the same role.

[0042] In this embodiment, the oxygen generation unit is at least one molecular sieve or nitrogen-oxygen separation membrane.

[0043] Among them, molecular sieves use pressure swing adsorption to separate nitrogen and oxygen in compressed air to prepare high-concentration oxygen (i.e., oxygen). One molecular sieve can be used, or multiple molecular sieves can be used.

[0044] The nitrogen-oxygen separation membrane uses membrane separation to separate nitrogen and oxygen in compressed air to produce high-concentration oxygen (i.e., oxygen). One or multiple separation membranes can be used.

[0045] When the oxygen generation unit has two or more molecular sieves, an electromagnetic reversing valve is installed between the cooling device and the molecular sieves.

[0046] For example, this embodiment uses two molecular sieves, referring to... Figure 13 As shown, when oxygen production begins, the reversing valve opens the first molecular sieve, allowing compressed air to enter for nitrogen-oxygen separation. The first molecular sieve adsorbs nitrogen, while oxygen is delivered. When the first molecular sieve is saturated with adsorbed nitrogen, the reversing valve switches to allow compressed air to flow to the second molecular sieve, which then begins to operate. Simultaneously, the first molecular sieve discharges the adsorbed nitrogen to restore its adsorption function. When the second molecular sieve is saturated with adsorbed nitrogen, the reversing valve switches to allow compressed air to flow to the first molecular sieve, which then begins to operate. Simultaneously, the second molecular sieve discharges the adsorbed nitrogen to restore its adsorption function. The two molecular sieves alternately perform nitrogen-oxygen separation, ensuring uninterrupted oxygen production.

[0047] Reference Figure 1 As shown, the salt aerosol branch 3 includes a salt particle assembly, a second pressure regulating valve and a second check valve are provided between the salt particle assembly and the condenser, and a third check valve is provided between the salt particle assembly and the mixing section.

[0048] The second check valve only allows compressed air to flow from the air compressor to the salt aerosol branch 3, and does not allow the salt aerosol generated in the salt aerosol branch to flow back into the air compressor.

[0049] The third one-way valve only allows salt aerosol to flow from the salt microparticle assembly to the mixing section, and does not allow oxygen to flow back into the salt microparticle assembly.

[0050] It is understood that in this embodiment, not only can a pressure regulating valve be used to regulate the gas flow rate, but a stepper motor in conjunction with a screw structure can also be used to regulate the gas flow rate, or other devices capable of regulating the flow rate. In this utility model, it is not limited to a pressure regulating valve, and other equivalent devices for regulating the flow rate are also included.

[0051] Reference Figure 2 In one embodiment of the oxygen generation branch 2 shown, a first flow sensor, an oxygen concentration sensor, and a first check valve are provided between the first pressure regulating valve and the mixing section. Specifically, the first one-way valve only allows oxygen to flow from the oxygen generation unit to the mixing section, and not in the reverse direction; the first flow sensor is used to detect the oxygen flow rate after pressure regulation; and the oxygen concentration sensor is used to detect the oxygen concentration before mixing with the salt aerosol. Reference Figure 3 In one embodiment of the salt aerosol branch 3 shown, a second flow sensor and a salt aerosol concentration sensor are provided between the salt particle assembly and the third check valve.

[0052] The second flow sensor is used to detect the flow rate of the salt aerosol branch 3, and the concentration sensor is used to detect the concentration of the salt aerosol.

[0053] It is understood that in this embodiment, not only can a pressure regulating valve be used to regulate the gas flow rate, but a stepper motor in conjunction with a screw structure can also be used to regulate the gas flow rate, or other devices capable of regulating the flow rate. In this utility model, it is not limited to a pressure regulating valve, and other equivalent devices for regulating the flow rate are also included.

[0054] Reference Figure 4 An embodiment of the salt particle assembly in the salt aerosol branch 3 shown is a salt box containing pre-made salt particles and equipped with an air inlet and an air outlet. Compressed air generated by the air compressor can blow out the salt particles in the salt box to form a salt aerosol after being regulated by the second pressure regulating valve. Another embodiment of the salt microparticle assembly is a grinding chamber, which includes a chamber body and grinding tools. The chamber body has an air inlet and an air outlet. The grinding tools are located inside the chamber body and can cut and grind the rock salt ingredients inside the chamber body into tiny salt particles. The compressed air generated by the air compressor can blow out the ground salt particles to form a salt sol after being regulated by a second pressure regulating valve.

[0055] Reference Figure 5 In another embodiment of the salt microparticle assembly shown, the salt microparticle assembly comprises a salt spray generator and an evaporator. The salt spray generator is a micro-mesh atomizer. The evaporator is connected to both the micro-mesh atomizer and a condenser. The micro-mesh atomizer atomizes the salt solution into tiny droplets of liquid mist and sprays the liquid mist into the evaporator. The evaporator evaporates and dries the liquid mist into dry salt microparticles. Compressed air, after being pressurized by a second pressure regulating valve, is introduced into the evaporator to accelerate the drying speed of the liquid mist generated by the micro-mesh atomizer and carries away the dried salt microparticles.

[0056] In this embodiment, there is no need to introduce a humidifier to humidify the mixed gas after mixing oxygen and salt aerosol, nor is it necessary to set up a heating component to heat the mixed gas.

[0057] Reference Figure 6 The example shown is an embodiment of a gas path system in which the salt microparticle assembly is a micro-mesh atomizer and evaporator.

[0058] Reference Figure 7 As shown, another embodiment of the salt microparticle assembly is a salt spray generator and an evaporator, wherein the salt spray generator is a compression atomizing cup or an ultrasonic atomizer.

[0059] In one example of this embodiment, the salt spray generator is an ultrasonic atomizer. The air pressure regulated by the second pressure regulating valve is first connected to the ultrasonic atomizer and then to the evaporator. The ultrasonic atomizer atomizes the salt solution into a liquid mist of tiny droplets. The pressure-regulated air carries the liquid mist out to the evaporator to evaporate and dry it into dry salt particles. The salt particles are then carried out to form a salt aerosol, which then passes through the second flow sensor, the salt aerosol concentration sensor, and the third one-way valve before being introduced into the mixing section to mix with oxygen.

[0060] In this embodiment, there is no need to introduce a humidifier to humidify the mixed gas after mixing oxygen and salt aerosol, nor is it necessary to set up a heating component to heat the mixed gas.

[0061] In another example of this embodiment, the salt spray generator is a compression atomizing cup. Air, after being regulated by the second pressure regulating valve, is first introduced into the compression atomizing cup to atomize the salt solution into liquid mist. The liquid mist is then carried into the evaporator to evaporate and dry the liquid mist into tiny salt particles. The salt particles are then blown out to form a salt aerosol, which is then passed through the second flow sensor, the salt aerosol concentration sensor, and the third one-way valve before being introduced into the mixing section to mix with oxygen.

[0062] In this embodiment, there is no need to introduce a humidifier to humidify the mixed gas after mixing oxygen and salt aerosol, nor is it necessary to set up a heating component to heat the mixed gas.

[0063] In the above embodiments, the evaporator evaporates and dries the liquid mist by means of heating drying, microwave drying, infrared drying, etc.

[0064] Microwave drying and infrared drying can be used by placing the corresponding microwave generator or infrared generator on the cavity wall of the evaporator to dry the liquid mist entering the evaporator.

[0065] Heating and drying can be achieved by using heating wires or heating plates, which are installed on the cavity wall of the evaporator to heat the entire evaporator and dry the liquid mist entering the evaporator. When the salt spray generator is a micro-mesh atomizer, the heating wire or heating plate can also be set at the air inlet of the evaporator after the air pressure is regulated by the second pressure regulating valve. When the regulated air enters the evaporator, it is heated by the heating wire or heating plate to form hot air. The hot air enters the evaporator to dry the liquid mist.

[0066] like Figure 8In one embodiment of the mixing section 4 shown, the mixing section 4 is a section of the ventilation line, or a mixing chamber designed separately on the ventilation line; after the oxygen generated by the oxygen generating branch 2 and the salt aerosol generated by the salt aerosol branch 3 are mixed in the mixing section 4, the mixture is supplied to the patient for inhalation through a breathing mask.

[0067] It is known that the oxygen-salt aerosol mixture is not limited to being inhaled by a breathing mask; it can also be a nasal tube, nasal plug, endotracheal tube, mouthpiece, or other device that can deliver the oxygen-salt aerosol mixture to the patient's airway.

[0068] like Figure 9 In another embodiment of the mixing section 4 shown, the mixing section 4 is the space between the breathing mask and the user's nasal cavity and / or oral cavity, that is, the oxygen generated by the oxygen generation branch 2 and the salt aerosol generated by the salt aerosol branch 3 are respectively delivered to the breathing mask, and after preliminary mixing in the breathing mask, they are inhaled into the lungs by the patient.

[0069] In this embodiment, the breathing mask is provided with two air inlets, one for oxygen and the other for salt aerosol.

[0070] Reference Figure 10 In another embodiment of the mixing unit 4 shown, the mixing unit 4 is a relatively enclosed treatment space, including an oxygen chamber, a treatment chamber, a treatment room, a bedroom, etc. The oxygen generated by the oxygen generating branch 2 and the salt aerosol generated by the salt aerosol branch 3 are diffused and mixed in the treatment space, and the user inhales the mixed gas of oxygen and salt aerosol in the treatment space for treatment.

[0071] In this invention, the mixing section 4 is not limited to the listed examples; any space for mixing oxygen generated by the oxygen generation branch 2 with salt aerosol generated by the salt aerosol branch 3 can be called the mixing section 4.

[0072] like Figure 11 As shown, in one embodiment where the cooling device is a transducer, the inlet end of the transducer is connected to an air compressor, and the outlet end is connected to the oxygen generation branch 2 and the salt aerosol branch 3 respectively. The compressed gas output by the air compressor is cooled by the transducer and then sent to the oxygen generation branch 2 and the salt aerosol branch 3 respectively. The transducer is also connected to the mixing section, and while performing the function of a condenser, it can collect the heat of the compressed air and transfer it to the mixing section to heat the mixed gas in the mixing section, eliminating the need for an additional heating device to heat the mixed gas.

[0073] This embodiment applies to situations where the salt microparticle assembly is a salt box or a grinding chamber.

[0074] Reference Figure 12As shown, the cooling device is another embodiment of the transducer. The inlet end of the transducer is connected to an air compressor, and the outlet end is connected to the oxygen generation branch 2 and the salt aerosol branch 3 respectively. After cooling the compressed air, it is delivered to the oxygen generation branch 2 and the salt aerosol branch 3. At the same time, it is also connected to the evaporator. While realizing the function of the condenser, it can collect the heat of the compressed air and transfer it to the evaporator for use in liquid mist drying.

[0075] This embodiment applies to situations where the salt microparticle components are salt spray generators and evaporators.

[0076] In this embodiment, the particle size distribution of the salt aerosol is as follows: particles with a diameter of less than 5 μm account for more than 90%.

[0077] In this embodiment, the oxygen concentration produced by the oxygen-generating branch is greater than 90%.

[0078] Reference Figure 14 As shown, an integrated oxygen therapy and saline therapy device includes a power supply module, a control module, and the single-gas-source gas path system described in this utility model. The power supply module simultaneously supplies power to the gas source 1, the oxygen generation branch 2, the saline aerosol branch 3, and the control module. The control module controls the operating parameters of the gas source 1, the oxygen generation branch 2, and the saline aerosol branch 3, allowing users to simultaneously inhale oxygen for oxygen therapy and inhale saline aerosol for saline therapy, treating hypoxia, respiratory diseases, promoting sputum expectoration, and relieving airway mucosal edema, etc.

[0079] For example, refer to Figure 13 As shown, the cooling device is a condenser 104, the salt particle assembly is a combination of a micro-mesh atomizer 301 and an evaporator 302, a heating element is provided at the air inlet of the compressed air into the evaporator 302, the oxygen generation unit is a reversing valve 201, two molecular sieves (first molecular sieve 202 and second molecular sieve 203) and an oxygen storage section 204, and the mixing section 4 is a mixing chamber; The specific process of one embodiment of this utility model is as follows: When the power is turned on, the control module controls the air compressor 103, oxygen generation branch 2, and salt sol branch 3 to start working. Air enters the air compressor 103 through the air inlet 101 and filter 102. The air compressor 103 compresses the filtered air and delivers it to the condenser 104. The condenser 104 cools and removes moisture from the compressed air (i.e., cools and dries the compressed air). Two air paths are output through the first three-way valve 105. One of these air paths connects to the oxygen generation branch and is delivered to the first molecular sieve 202 or the second molecular sieve 202 via the reversing valve 201. Nitrogen and oxygen are separated in molecular sieve 203. The nitrogen adsorbed in the first molecular sieve 202 or the second molecular sieve 203 is discharged after nitrogen removal. The oxygen separated by the first molecular sieve 202 or the second molecular sieve 203 is transported to the oxygen storage section 205 for storage after passing through the second three-way valve 204. The oxygen in the oxygen storage section 205 (also known as oxygen-enriched gas) is regulated by the first pressure regulating valve 206 and then enters the mixing section 4 (i.e., the mixing chamber) through the first one-way valve 209. At the same time, the first flow sensor 207, which is set between the first pressure regulating valve 206 and the first one-way valve 209, measures the oxygen flow rate after pressure regulation, and the oxygen concentration sensor 208 measures the oxygen concentration. The compressed air output from the condenser 104 passes through the first three-way valve 105 and then through another air path. After the pressure is adjusted by the second pressure regulating valve 601, it is connected to the evaporator 302 of the salt aerosol branch 3 via the second one-way valve 602. In the salt aerosol branch 3, the micro-mesh atomizer 301 atomizes the salt solution into tiny droplets of liquid mist and sprays them into the evaporator 302. The compressed air, after the pressure is adjusted by the second pressure regulating valve 601, is heated by the heating element to form hot air. The hot air is passed into the evaporator 302 to evaporate and dry the liquid mist into dry salt particles. The salt particles are then blown out of the evaporator 302 to form salt aerosol. The salt aerosol is then carried through the second flow sensor 303, the salt aerosol concentration sensor 304, and the third one-way valve 305 before entering the mixing section 4 to mix with oxygen. The mixed oxygen-salt aerosol gas is then supplied to the user for inhalation through the breathing mask 501 to treat respiratory diseases.

The first pressure regulating component and the second pressure regulating component referred to in this utility model are not limited to pressure regulating valves, but also include other equivalent devices for regulating the flow rate.
