Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of hyperbaric oxygen chambers, specifically to a device for reducing the oxygen and carbon dioxide concentrations in hyperbaric oxygen chambers. Background Technology
[0002] Hyperbaric oxygen chambers are specialized medical devices for hyperbaric oxygen therapy. In recent years, as the elderly have paid more attention to health preservation, the manufacturing standards for hyperbaric oxygen chambers with pressures slightly above atmospheric pressure have become less stringent in terms of safety requirements, and advancements in industrial technology have led to the widespread adoption of micro-hyperbaric oxygen chambers with pressures slightly above atmospheric pressure that can be brought into homes. Furthermore, studies by multiple organizations have concluded that moderate exposure to environments with pressures above atmospheric pressure is beneficial to the physiological activities of the elderly, and can play a positive role in improving their quality of life and alleviating some physical discomforts.
[0003] Current hyperbaric oxygen chambers are completely sealed. When a person inhales oxygen inside, not all the oxygen is absorbed, causing it to diffuse within the chamber and increase its concentration. Simultaneously, the person exhales an equal molar amount of carbon dioxide, worsening the air quality and impacting the user's health. Conventional methods involve increasing the air intake to dilute the oxygen and carbon dioxide concentrations. To maintain these concentrations below safe levels, this would require injecting 1000 times the volume of oxygen and carbon dioxide into the chamber, resulting in excessive energy consumption and high costs. Utility Model Content
[0004] Therefore, it is necessary to provide a device for reducing the oxygen and carbon dioxide concentrations in a hyperbaric oxygen chamber.
[0005] A device for reducing oxygen and carbon dioxide concentrations in a hyperbaric oxygen chamber includes an oxygen mask, an oxygen inlet valve, an exhaust valve, a compressed air inlet valve, and a pressure relief valve. The oxygen mask is used to provide oxygen to the user. The oxygen mask is connected to the exhaust valve. The oxygen inlet valve, the compressed air inlet valve, and the pressure relief valve are respectively installed at preset positions in the hyperbaric oxygen chamber and are respectively connected to the internal space of the hyperbaric oxygen chamber.
[0006] In one embodiment, the device further includes a breathing detection sensor installed inside the oxygen mask for detecting the breathing status of the person receiving oxygen.
[0007] In one embodiment, the device further includes oxygen and carbon dioxide concentration detectors installed inside the hyperbaric oxygen chamber to detect the oxygen and carbon dioxide concentrations inside the chamber and send the detected oxygen and carbon dioxide concentration values to the control module.
[0008] When both oxygen and carbon dioxide concentrations are below the preset threshold, the pressure relief valve closes. When either oxygen or carbon dioxide concentration is above the preset threshold, the compressed air intake valve and the pressure relief valve open simultaneously to dilute the gas in the hyperbaric oxygen chamber.
[0009] In one embodiment, the control module is electrically connected to the oxygen inlet valve, the extraction valve, the compressed air inlet valve, and the pressure relief valve, respectively.
[0010] In one embodiment, the control module includes a timer that controls the opening or closing of the compressed air intake valve and the pressure relief valve at preset times.
[0011] In one embodiment, the oxygen mask is provided with an oxygen inlet and an exhaust port. The oxygen inlet is connected to the interior space of the hyperbaric oxygen chamber, and the exhaust port is connected to the exhaust valve.
[0012] In one embodiment, the oxygen and carbon dioxide concentration detectors are multi-parameter air quality gas sensors.
[0013] In one embodiment, the control module is either a microcontroller or an MCU module.
[0014] The aforementioned device for reducing oxygen and carbon dioxide concentrations in a hyperbaric oxygen chamber utilizes a combination of an oxygen mask, an oxygen inlet valve, an exhaust valve, a compressed air inlet valve, and a pressure relief valve. A preset amount of oxygen is injected into the hyperbaric oxygen chamber through the oxygen inlet valve, allowing the user to inhale oxygen through the mask. The exhaust valve removes the carbon dioxide exhaled by the user, expelling it from the chamber. Only a small amount of residual and leaked carbon dioxide remains inside. This requires very little air to dilute the oxygen and carbon dioxide levels in the hyperbaric oxygen chamber, reducing air supply, energy consumption, cost, and equipment lifespan. Attached Figure Description
[0015] Figure 1 This is a schematic diagram of a device for reducing oxygen and carbon dioxide concentrations in a hyperbaric oxygen chamber according to an embodiment of the present invention. Detailed Implementation
[0016] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0017] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediary component present. Conversely, when a component is said to be "directly" connected to another component, there is no intermediary component.
[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0019] like Figure 1 As shown, a device for reducing oxygen and carbon dioxide concentrations in a hyperbaric oxygen chamber includes an oxygen mask 1, an oxygen inlet valve 2, an exhaust valve 3, a compressed air inlet valve 4, and a pressure relief valve 5. The oxygen mask 1 is used to provide oxygen to the user. The oxygen mask 1 is connected to the exhaust valve 3. The oxygen inlet valve 2, the compressed air inlet valve 4, and the pressure relief valve 5 are respectively installed at preset positions in the hyperbaric oxygen chamber 6 and are respectively connected to the internal space of the hyperbaric oxygen chamber 6.
[0020] The device also includes oxygen and carbon dioxide concentration detectors 7, which are installed inside the hyperbaric oxygen chamber 6 to detect the oxygen and carbon dioxide concentrations inside the hyperbaric oxygen chamber 6 and send the detected oxygen and carbon dioxide concentration values to the control module.
[0021] When the oxygen and carbon dioxide concentrations are both below the preset threshold, the pressure relief valve 5 closes. When the oxygen or carbon dioxide concentration is above the preset threshold, the compressed air intake valve 4 and the pressure relief valve 5 open simultaneously to dilute the gas in the hyperbaric oxygen chamber 6.
[0022] The control module is electrically connected to the oxygen inlet valve 2, the exhaust valve 3, the compressed air inlet valve 4, and the pressure relief valve 5 respectively; the oxygen mask 1 is provided with an oxygen inlet 11 and an exhaust port 12. The oxygen inlet 11 is connected to the internal space of the hyperbaric oxygen chamber 6, and the exhaust port 12 is connected to the exhaust valve 3.
[0023] The oxygen and carbon dioxide concentration detector 7 is a multi-parameter air quality gas sensor, and the control module is either a microcontroller or an MCU module.
[0024] Oxygen of a preset molar quantity is injected into the hyperbaric oxygen chamber 6 through the oxygen inlet valve 2. The patient wears an oxygen mask 1 and inhales oxygen through the oxygen inlet 11 on the mask. The exhaust port 12 is connected to one end of the exhaust valve 3, and the other end of the exhaust valve 3 is connected to an external exhaust device. The exhaust device extracts a large amount of carbon dioxide exhaled by the patient from the oxygen mask 1, while a small portion of the unextracted carbon dioxide enters the chamber. Oxygen and carbon dioxide concentration detectors 7 monitor the oxygen and carbon dioxide concentrations in the hyperbaric oxygen chamber 6 in real time and send the detected values to the control module. When both oxygen and carbon dioxide concentrations are below preset thresholds, the pressure relief valve 5 closes. When either oxygen or carbon dioxide concentration is above the preset threshold, the compressed air inlet valve 4 and the pressure relief valve 5 open simultaneously. An appropriate amount of air is injected through the compressed air inlet valve 4, while the pressure relief valve 5 opens, expelling some of the oxygen and carbon dioxide from the hyperbaric oxygen chamber 6 and diluting the gas inside.
[0025] In this way, the device for reducing the oxygen and carbon dioxide concentrations in the hyperbaric oxygen chamber is configured with the cooperation of an oxygen mask 1, an oxygen inlet valve 2, an exhaust valve 3, a compressed air inlet valve 4, and a pressure relief valve 5. The oxygen inlet valve 2 injects a preset amount of oxygen into the hyperbaric oxygen chamber 6, and the person inhaling oxygen inhales oxygen from the hyperbaric oxygen chamber 6 through the oxygen mask 1. The exhaust valve 3 extracts the carbon dioxide exhaled by the person inhaling oxygen and discharges it from the hyperbaric oxygen chamber 6, leaving only a small amount of residual and leaked carbon dioxide inside the chamber. Only a small amount of air is needed to dilute the oxygen and carbon dioxide in the hyperbaric oxygen chamber 6, reducing the amount of air supplied, lowering energy consumption, reducing costs, and extending the life of the equipment.
[0026] In one embodiment, the device further includes a breathing detection sensor installed inside the oxygen mask 1 for detecting the breathing status of the person receiving oxygen.
[0027] In this way, by setting up a breathing detection sensor, the breathing detection sensor is used to detect whether the oxygen user is in an inhalation or exhalation state, and sends the breathing status information to the control module. When the oxygen user is in an inhalation state, the control module controls the suction device to stop working; when the oxygen user is in an exhalation state, the control module controls the suction device to start working, and extracts the exhaled carbon dioxide from the oxygen mask 1 through the suction valve 3, which is more accurate in extracting carbon dioxide.
[0028] In one embodiment, the control module includes a timer that controls the opening or closing of the compressed air intake valve 4 and the pressure relief valve 5 at preset times.
[0029] In this way, by setting the timer, the control module controls the compressed air intake valve 4 and the pressure relief valve 5 to open according to the preset time. The compressed air intake valve 4 injects a preset amount of air, and the pressure relief valve 5 discharges some of the oxygen and carbon dioxide in the hyperbaric oxygen chamber 6, thereby reducing the concentration of oxygen and carbon dioxide in the hyperbaric oxygen chamber 6.
[0030] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
