Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a 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 respiratory diseases affect a patient's vital capacity and oxygenation capacity, leading to decreased blood oxygen saturation, the first priority 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, results in 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 gas path system and an integrated oxygen and saline therapy device. By designing a gas path system, users can simultaneously perform oxygen and saline therapy, reducing usage costs and simplifying operation.

[0005] To achieve the above objectives, the specific solution of this utility model is a gas path system, including an oxygen generation branch, a salt aerosol branch, and a mixing chamber; The oxygen-generating branch separates nitrogen and oxygen in the air to provide users with oxygen-enriched gas; The saline aerosol branch is used to generate dry saline aerosols to provide saline aerosol therapy for users. The mixing chamber connects the oxygen generation branch and the saline aerosol branch. It is used to mix the oxygen-enriched gas generated by the oxygen generation branch with the saline aerosol generated by the saline aerosol branch, and is connected to the user's inhalation end to deliver the mixed gas to the user. The oxygen generation branch and the salt aerosol branch do not interfere with each other and operate independently.

[0006] The oxygen generation branch includes an oxygen generation unit, a first compressor that provides fresh air to the oxygen generation unit, an oxygen storage unit that stores oxygen, and a pressure regulating component that controls the oxygen output flow rate. The first compressor, the oxygen generation unit, the oxygen storage unit, and the pressure regulating component are connected in sequence through a ventilation pipeline.

[0007] Furthermore, the first compressor inlet is equipped with a filter for preliminary filtration of the air entering the first compressor; a condenser is provided between the first compressor and the oxygen generating unit for filtering moisture in the gas output from the first compressor and providing dry gas for the oxygen generating unit; a first one-way valve, a first flow sensor, and an oxygen concentration sensor are provided between the pressure regulating component and the mixing chamber.

[0008] Specifically, the oxygen generating unit is at least one molecular sieve or nitrogen-oxygen separation membrane, the oxygen storage part is an oxygen storage tank or a gas collection chamber, and the pressure regulating component is an electromagnetic pressure regulating valve or a stepper motor.

[0009] Specifically, when the oxygen generating unit consists of two or more molecular sieves, an electromagnetic reversing valve is installed between the condenser 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.

[0010] Furthermore, the salt aerosol branch includes a second gas source and a salt particle assembly.

[0011] Furthermore, a second one-way valve, a second flow sensor, and a salt aerosol concentration sensor are provided between the salt particle assembly and the mixing chamber.

[0012] In one technical solution, the second air source is a fan or blower; The salt microparticle assembly is a salt box, which stores pre-made salt microparticles and is equipped with an air inlet and an air outlet. The second air source blows the salt microparticles out of the salt box to form a salt sol. Alternatively, 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 located inside the chamber body and can cut and grind the rock salt ingredients inside the chamber body into tiny salt microparticles. The second air source can blow out the ground salt microparticles to form a salt sol.

[0013] In another technical solution, the salt particle assembly consists of a salt spray generator and an evaporator. The salt spray generator atomizes the salt solution into a liquid mist of tiny droplets, and the evaporator evaporates and dries the liquid mist into dry salt particles. The second air source blows out the salt particles to form a salt aerosol.

[0014] Specifically, the methods by which evaporators evaporate and dry liquid mist include heating drying, microwave drying, and infrared drying.

[0015] The microwave drying and infrared drying methods involve placing corresponding microwave and infrared generators on the cavity wall of the evaporator to dry the liquid mist entering the evaporator.

[0016] The heating and drying process can be carried out 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. Alternatively, the heating wire or heating element is placed at the inlet of the evaporator to heat the air introduced into the evaporator from the second air source, and then the heated hot air is used to dry the liquid mist entering the evaporator.

[0017] Furthermore, the salt spray generator is a compression atomizing cup, a micro-mesh atomizer, or an ultrasonic atomizer; When the salt spray generator is a micro-mesh atomizer, the second air source is a fan or blower, which is connected to the evaporator to accelerate the drying speed of the liquid mist generated by the micro-mesh atomizer and carry out the salt particles generated after drying. When the salt spray generator is an ultrasonic atomizer, the second air source is a fan or blower. First, connect the ultrasonic atomizer to carry the liquid mist generated by the ultrasonic atomizer to the evaporator for drying, and carry out the salt particles generated after drying. The salt spray generator is a compression atomizing cup, and the second air source is a second compressor. The second compressor first passes the salt solution into the compression atomizing cup to atomize it into liquid mist, and then connects to the evaporator to dry the liquid mist, and carries away the salt particles generated after drying.

[0018] Furthermore, the mixing chamber is a section of pipe installed on the ventilation pipe; Alternatively, it could be a separately designed mixing space located within the ventilation duct. Alternatively, it refers to the space between the breathing mask and the user's nasal cavity and / or mouth.

[0019] In another application scenario, the oxygen generated by the oxygen-generating branch and the salt aerosol generated by the salt aerosol branch are not mixed, but are directly released into the oxygen chamber, treatment chamber, or treatment room respectively. They are initially mixed in the oxygen chamber, treatment chamber, or treatment room by free diffusion and then inhaled by the user for treatment. The user is in the oxygen chamber, treatment chamber, or treatment room.

[0020] Furthermore, the second air source inlet is equipped with a filter screen to filter the air entering the second air source.

[0021] Furthermore, the pressure regulating component is an electromagnetic pressure regulating valve, a stepper motor, or other device for regulating gas flow.

[0022] This utility model also provides an integrated oxygen therapy and saline therapy device, including the above-mentioned airway system, which allows users to inhale saline aerosol for saline therapy while receiving oxygen therapy, in order to treat respiratory diseases, promote expectoration, and relieve airway mucosal edema.

[0023] 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. When the liquid mist is dried and evaporated in the salt aerosol branch, the water vapor generated by the liquid mist is mixed with the oxygen-enriched gas along 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. 3. After the liquid mist is dried and evaporated in the salt aerosol branch to form salt aerosol, the salt aerosol carries the heat from the evaporator and mixes with the oxygen-enriched gas 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. 4. Oxygen generation and saline aerosol can operate independently, allowing for saline aerosol therapy or oxygen therapy alone, or both simultaneously. Only one control module and power supply module are needed to control the working parameters of oxygen therapy and saline therapy at the same time. Users can freely choose from three modes to achieve multiple uses with one machine, reducing the burden on users and simplifying operation. 5. The operating power of the second air source is much less than that of the air compressor. When only the oxygen therapy mode is turned on, energy consumption and noise can be reduced, energy can be saved, and the user can have a comfortable treatment environment.

[0027] 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.

[0028] Reference Figure 1 As shown, an embodiment of a gas path system includes an oxygen generation branch 1, a salt aerosol branch 2, and a mixing chamber; The oxygen generation branch 1 separates nitrogen and oxygen in the air to provide users with oxygen-enriched gas; The saline aerosol branch 2 is used to generate dry saline aerosols to provide saline aerosol therapy for users. The mixing chamber 3 is connected to the oxygen generation branch 1 and the salt aerosol branch 2. It is used to mix the oxygen-enriched gas generated by the oxygen generation branch 1 with the salt aerosol generated by the salt aerosol branch 2, and is connected to the user's inhalation end to deliver the mixed gas to the user. Oxygen generation branch 1 and salt aerosol branch 2 each use separate gas sources, do not interfere with each other, and operate independently.

[0029] In this embodiment, the oxygen generation branch 1 includes an oxygen generation unit, a first compressor that provides fresh air to the oxygen generation unit, an oxygen storage unit that stores oxygen, and a pressure regulating component that controls the oxygen output flow rate. The first compressor, the oxygen generation unit, the oxygen storage unit, and the pressure regulating component are connected in sequence through a ventilation pipeline.

[0030] It is understood that the oxygen storage unit referred to in this embodiment refers to a device for storing oxygen, which may be an oxygen storage tank, a gas collection chamber, or other device or structure for storing oxygen. The pressure regulating component is an electromagnetic pressure regulating valve, a stepper motor, or other device that can regulate gas flow.

[0031] Reference Figure 3 As shown, in one embodiment of the oxygen generation branch 1, a filter is provided at the air inlet of the first compressor to perform preliminary filtration of the air entering the first compressor and filter out solid particles in the air; a condenser is provided between the first compressor and the oxygen generation unit to filter out moisture in the gas output by the first compressor and provide dry gas for the oxygen generation unit; a first check valve, a first flow sensor, and an oxygen concentration sensor are provided between the pressure regulating valve and the mixing chamber 3.

[0032] The first one-way valve allows oxygen-enriched gas to flow only from the oxygen generation unit to the mixing chamber, 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 of the oxygen-enriched gas before it is mixed with the salt aerosol.

[0033] The filter, the first compressor, and the condenser are the first air sources, used to provide clean air to the oxygen generation unit.

[0034] In this embodiment, the oxygen generation unit consists of two molecular sieves. An electromagnetic reversing valve is installed between the condenser and the molecular sieves. When the nitrogen adsorbed by the first molecular sieve becomes saturated, the reversing valve switches the valve to start the second molecular sieve. 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 switches the valve to start the first molecular sieve. At the same time, the second molecular sieve discharges the adsorbed nitrogen to restore its adsorption function. The two molecular sieves alternate in sequence, which can generate oxygen continuously.

[0035] The specific working process of the oxygen generation branch is as follows: the compressor compresses the filtered air, and the compressed air enters the condenser to condense and remove the moisture in the air, thereby increasing the oxygen generation efficiency. After the moisture is removed by condensation, the gas is passed into the molecular sieve for nitrogen and oxygen separation. The separated nitrogen is discharged, and the separated oxygen is sent to the oxygen storage tank for storage. The pressure and flow rate in the oxygen storage tank are regulated by the pressure regulating valve, and then the oxygen enters the mixing chamber after passing through the first flow sensor, oxygen concentration sensor, and first one-way valve to mix with the salt aerosol.

[0036] It is known that the number of molecular sieves is not limited to two; it can be one or more to form an oxygen generator unit.

[0037] It is known that the oxygen generating component can also be prepared using membrane separation. In another embodiment, the oxygen generating component uses a nitrogen-oxygen separation membrane to separate nitrogen and oxygen in the air to produce oxygen.

[0038] It is known that cryogenic methods can also be used for preparation, or any combination of two of cryogenic methods, membrane separation methods, and pressure swing adsorption (molecular sieves).

[0039] Reference Figure 1 As shown, one embodiment of the salt aerosol branch 2 includes a second gas source and a salt particle assembly. The second gas source flows the gas into the salt particle assembly, carries out the salt particles generated by the salt particle assembly to form a salt aerosol, and carries the salt aerosol to the mixing chamber 3 to mix with the oxygen-enriched gas generated by the oxygen generation branch 1.

[0040] Reference Figure 4 As shown, in another embodiment of the salt aerosol branch 2, a second one-way valve, a second flow sensor, and a salt aerosol concentration sensor are provided between the salt particle assembly and the mixing chamber.

[0041] The second one-way valve allows salt aerosol to flow from the salt particle assembly to the mixing chamber while preventing gas in the mixing chamber from flowing to the salt particle assembly; the second flow sensor is used to detect the flow rate of the gas carrying the salt aerosol; and the salt aerosol concentration sensor is used to detect the concentration of the salt aerosol.

[0042] In some embodiments, the salt aerosol concentration sensor has a particle size detection function, which can detect the particle size distribution of salt aerosols while detecting the salt aerosol concentration.

[0043] like Figure 5 As shown, in one embodiment of the salt microparticle assembly in the salt aerosol branch 2, the salt microparticle assembly is a salt box containing pre-made salt microparticles. The salt box has an air inlet and an air outlet. A second air source blows the salt microparticles out of the salt box to form a salt aerosol.

[0044] In this embodiment, the second gas source can be a fan or a blower, without the need to compress the gas.

[0045] In this embodiment, the second gas source is directly connected to the salt box. After the salt particles in the salt box are blown out to form a salt aerosol, they pass through the second flow sensor, the salt aerosol concentration sensor, and the one-way valve in sequence before entering the mixing chamber to mix with the oxygen-enriched gas.

[0046] In this embodiment, the salt microparticle assembly can also use 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 located inside the chamber body and can cut and grind the rock salt ingredients inside the chamber body into tiny salt microparticles. The second air source can be a blower or fan to blow out the ground salt microparticles to form a salt sol.

[0047] In this embodiment, a humidification branch is also introduced to humidify the mixture of oxygen-rich gas and salt aerosol.

[0048] One design scheme for the humidification branch is as follows: the humidification branch includes a flow regulating valve and a humidifier. One end of the flow regulating valve is connected to the oxygen storage tank of the oxygen generation branch 1, and the other end is connected to the mixing chamber after passing through the humidifier. A third one-way valve is set between the humidifier and the mixing chamber.

[0049] Another option for the humidification branch is to directly connect it between the first one-way valve and the mixing chamber 3 to humidify the oxygen-enriched gas.

[0050] Reference Figure 6 As shown, another embodiment of the salt particle assembly in the salt aerosol branch 2 is illustrated. In this embodiment, the salt particle assembly consists of a salt mist generator and an evaporator. The salt mist generator is a micro-mesh atomizer, and the second air source is a fan. The evaporator is connected to both the micro-mesh atomizer and the fan. 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 particles. The second air source blows in fresh air to accelerate the drying speed of the liquid mist generated by the micro-mesh atomizer and carries away the dried salt particles.

[0051] It is understood that, in this embodiment, the second air source can also be a fan or other ventilation equipment that does not require air compression.

[0052] In this embodiment, there is no need to introduce a humidifier to humidify the mixed gas after mixing oxygen-enriched gas and salt aerosol, nor is it necessary to set up a heating component to heat the mixed gas.

[0053] Reference Figure 2 The image shows an example of a salt spray generator using a micro-mesh atomizer in the air path system.

[0054] Reference Figure 7As shown, another embodiment of the salt particle assembly in the salt aerosol branch 2 is shown. In this embodiment, the salt particle assembly is a salt mist generator and an evaporator, wherein the salt mist generator is a compression atomizing cup or an ultrasonic atomizer.

[0055] In one example of this embodiment, the salt spray generator is an ultrasonic atomizer, and the second air source is a fan or blower. The second air source is first connected to the ultrasonic atomizer, and then to the evaporator. The ultrasonic atomizer atomizes the salt solution into tiny droplets of liquid mist. The second air source blows in fresh air to carry the salt mist to the evaporator to evaporate and dry, forming a salt aerosol. The aerosol then passes through a second flow sensor, a salt aerosol concentration sensor, and a one-way valve before being introduced into the mixing chamber to mix with oxygen-enriched gas.

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

[0057] In another example of this embodiment, the salt spray generator is a compression atomizing cup, and the second air source is a second compressor. The second compressor compresses the air and first passes it into the compression atomizing cup to atomize the salt solution into liquid mist. Then, it carries the salt mist 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 then passes through a second flow sensor, a salt aerosol concentration sensor, and a one-way valve before being introduced into the mixing chamber to mix with oxygen-enriched gas.

[0058] In this embodiment, there is no need to introduce a humidifier to humidify the mixed gas after mixing oxygen-enriched gas and salt aerosol, nor is it necessary to set up a heating component to heat the mixed gas.

[0059] In the above embodiments, the evaporator evaporates and dries the liquid mist by means of heating drying, microwave drying, infrared drying, etc.

[0060] 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.

[0061] 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 second air source into the evaporator. When the gas from the second air source enters the evaporator, it is heated to form hot air as it passes through the heating wire or heating plate. The heated hot air is then used to dry the liquid mist entering the evaporator.

[0062] like Figure 8As shown, the mixing chamber 3 is a section of the ventilation line, or a separately designed mixing space on the ventilation line; the oxygen-enriched gas generated by the oxygen-generating branch 1 and the salt aerosol generated by the salt aerosol branch 2 are mixed in the mixing chamber 3 and then inhaled into the lungs of the patient through a breathing mask.

[0063] 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.

[0064] like Figure 9 As shown, the mixing chamber 3 is the space between the breathing mask and the user's nasal cavity and / or oral cavity. That is, the oxygen-enriched gas generated by the oxygen-generating branch 1 and the salt aerosol generated by the salt aerosol branch 2 are respectively delivered to the breathing mask, and after preliminary mixing in the breathing mask, they are inhaled into the lungs by the patient.

[0065] In this embodiment, the breathing mask is provided with two air inlets, one for oxygen-enriched gas and the other for salt aerosol.

[0066] In this invention, the space in which the oxygen-enriched gas generated by the oxygen-generating branch 1 mixes with the salt aerosol generated by the salt aerosol branch 2 can be referred to as the mixing chamber.

[0067] In another application scenario, the oxygen generated by oxygen generation branch 1 and the salt aerosol generated by salt aerosol branch 2 are not mixed. They are directly released into the oxygen chamber, treatment chamber, or treatment room, respectively. After initial mixing in the oxygen chamber, treatment chamber, or treatment room, they are inhaled by the user for treatment. The user must be in the oxygen chamber, treatment chamber, or treatment room.

[0068] Furthermore, the second air source inlet is equipped with a filter screen to filter the air entering the second air source.

[0069] In a further embodiment, the second air source inlet is equipped with a filter screen to filter the air entering the second air source.

[0070] 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%.

[0071] An integrated oxygen therapy and saline therapy device includes a power module, a control module, and the gas path system of this invention. The power module supplies power to the oxygen generation branch 1, the saline aerosol branch 2, and the control module. The control module controls the operating parameters of the oxygen generation branch 1 and the saline aerosol branch 2, 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.

[0072] 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 can also be used in conjunction with a screw structure to regulate the gas flow rate, or other devices capable of regulating the flow rate. The pressure regulating component referred to in this utility model is not limited to a pressure regulating valve, but also includes other equivalent devices for regulating the flow rate.

[0073] In this invention, the salt and rock salt mentioned refer to sodium chloride; the salt solution refers to a sodium chloride solution formed by dissolving sodium chloride in water, and may also contain trace amounts of elements such as magnesium and potassium; the salt aerosol has the same meaning as dry salt aerosol, rock salt aerosol, and salt sol, all of which are solid aerosols formed by dry salt particles suspended in the air; the salt mist generator is a device that atomizes salt solution into tiny droplets, and salt mist refers to the liquid mist formed by tiny droplets of salt solution suspended in the air.

[0074] Although the preferred embodiments of the present invention have been described above in conjunction with the accompanying drawings, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not limiting. Those skilled in the art can make many specific modifications under the guidance of the present invention without departing from the spirit of the invention and the scope of protection of the claims, and these modifications all fall within the protection scope of the present invention.
