Description

Technical Field

[0001] This application belongs to the field of medical device technology, specifically relating to an oxygen supply system. Background Technology

[0002] With the improvement of living standards and the advancement of medical technology, people are paying more and more attention to their health. This is especially true for those suffering from chronic respiratory diseases, such as COPD and asthma, for whom a continuous supply of oxygen is crucial. Pulsed oxygen concentrators are a common type of portable oxygen concentrator that provides a high concentration of oxygen only when the user inhales, thus improving oxygen utilization.

[0003] However, pulse oxygen concentrators deliver oxygen at a fast flow rate for a short time, which not only irritates the user's nasal cavity, but also wastes oxygen because the user cannot inhale a large amount in a short period of time. This results in poor comfort and treatment effect of pulse oxygen concentrators. Utility Model Content

[0004] This application aims to provide an oxygen supply system to solve the problem that existing pulse oxygen concentrators have a fast oxygen flow rate and short duration, resulting in poor user comfort and treatment effectiveness.

[0006] In a first aspect, this application discloses an oxygen supply system, including: an oxygen generating device, an oxygen inhalation device, and a regulator;

[0007] The oxygen generating device and the oxygen absorption device are arranged sequentially along the gas flow direction;

[0008] The regulator is disposed between the oxygen generating device and the oxygen inhalation device. The regulator includes a buffer element, which is connected to both the oxygen generating device and the oxygen inhalation device. The buffer element is used to reduce the flow rate of the gas.

[0009] Optionally, the buffer may expand or compress the gas to reduce the gas flow rate.

[0010] Optionally, the oxygen generating device includes an air outlet, the oxygen inhalation device includes an air inlet, and the buffer includes an outer wall and a buffer cavity formed by the outer wall, wherein the outer wall is elastic;

[0014] The first interface is connected to the air outlet so that the buffer chamber is in communication with the air outlet;

[0015] The second interface is connected to the air inlet so that the buffer chamber is in communication with the air inlet.

[0016] Optionally, the buffer is an elastic airbag. When the elastic airbag inflates, its volume increases, thereby reducing the flow rate of the gas.

[0017] Optionally, the regulator further includes: a speed control valve;

[0018] The speed regulating valve is disposed between the buffer and the air inlet and is connected to both the buffer and the air inlet. The speed regulating valve is used to regulate the flow rate of the gas into the air inlet.

[0019] Optionally, the regulator further includes a limiting shell, which is fitted onto the buffer to limit the expansion of the buffer.

[0020] Optionally, the limiting shell is provided with multiple weight-reducing holes.

[0022] Optionally, the oxygen generating device and the regulator are integrated into a single unit.

[0023] Alternatively, the oxygen inhalation device and the regulator may be integrated into a single unit.

[0024] In this embodiment, a regulator is installed between the oxygen generator and the oxygen inhalation device, and the regulator's buffer can reduce the gas flow rate.

[0044] This application provides an oxygen supply system, which will be described in detail below with reference to the accompanying drawings.

[0045] Reference Figures 1 to 4 A schematic diagram of a regulator is shown, with reference to... Figure 5 This diagram illustrates the changes in a buffer component during the use of a regulator, as provided in an embodiment of this application. Figure 6The diagram shows a structural schematic of the limiting shell provided in an embodiment of this application. (Refer to...) Figures 7 to 10 The diagram shows a schematic of a regulator with a limiting shell according to an embodiment of this application; see reference to Figure 11 This diagram illustrates the flow rate of oxygen output from a pulse oxygen concentrator without a regulator. (Refer to...) Figure 12 This diagram illustrates the flow rate of oxygen output from a pulse oxygen generator when a regulator is installed.

[0046] like Figures 1 to 4 As shown, this application provides an oxygen supply system, including: an oxygen generating device, an oxygen inhalation device, and a regulator; the oxygen generating device and the oxygen inhalation device are arranged sequentially along the gas flow direction X; the regulator is disposed between the oxygen generating device and the oxygen inhalation device, and the regulator includes a buffer 1, which is connected to the oxygen generating device and the oxygen inhalation device respectively, and the buffer 1 is used to reduce the gas flow rate.

[0047] In this embodiment, a regulator is provided between the oxygen generator and the oxygen inhalation device, and the buffer 1 of the regulator can reduce the gas flow rate. This effectively alleviates the irritation to the user's nasal cavity caused by the high gas flow rate, improving user comfort. Furthermore, it extends the gas output time, allowing more gas to be used by the user, thus improving oxygen utilization and treatment efficacy.

[0048] It should be noted that at the beginning of the oxygen supply system's operation, the gas entering the buffer 1 is air or a mixture of air and oxygen. As the oxygen supply system continues to operate, when all the air in the system is completely expelled, the gas entering the buffer 1 is oxygen. Furthermore, the oxygen generating device in this embodiment can be a pulse oxygen generator or other types of oxygen generating devices; the oxygen inhalation device can be a headset oxygen inhalation device, a nasal cannula oxygen inhalation device, a face mask oxygen inhalation device, or other types of oxygen inhalation devices, and is not limited thereto.

[0049] In some optional embodiments of this application, the buffer 1 can expand to reduce the gas flow rate. Thus, as oxygen from the oxygen generator enters the buffer 1, the expansion of the buffer 1 converts the kinetic energy of the oxygen into the elastic potential energy of the buffer 1, thereby reducing the oxygen flow rate. In one embodiment, the buffer 1 is made of soft rubber. Because soft rubber has low hardness and good elasticity, the expansion of the buffer 1 can buffer the oxygen as it enters. For example, the buffer 1 can be an elastic airbag, which is a structure capable of containing gas and expanding. Furthermore, in practical applications, the soft rubber buffer 1 can also be folded for storage to improve the portability of the regulator and facilitate its promotion and use.

[0050] In some optional embodiments of this application, the buffer 1 can compress the gas to reduce the gas flow rate. Thus, as oxygen from the oxygen generator enters the buffer 1, the compression of the oxygen within the buffer 1 converts its kinetic energy into internal energy, thereby reducing the oxygen flow rate. In another embodiment, the buffer 1 is made of hard rubber. Because hard rubber has relatively high hardness and relatively low elasticity, it can maintain a fixed volume. Thus, when oxygen with a short pulse output time and high flow rate (i.e., high instantaneous kinetic energy) enters the buffer chamber 11, the air resistance between the buffer chamber 11 and the outlet of the oxygen generator causes the oxygen entering the buffer chamber 11 to accumulate and be compressed to a certain extent. During this process, some of the oxygen's kinetic energy is converted into internal energy, reducing the oxygen flow rate and achieving a buffering effect. It is understood that because the buffer chamber 11 is connected sequentially to the oxygen inhalation device and the user's nasal cavity (where the user's nasal cavity is close to atmospheric pressure) to continuously deliver oxygen to the user, the degree of gas compression within the buffer chamber 11 is relatively small, and the buffering effect is less pronounced. To improve the cushioning effect of the rigid rubber buffer 1, it is usually necessary to increase the volume of the buffer chamber 11 and / or reduce the size of the oxygen inlet pipe of the oxygen supply device. For example, the buffer 1 can be a tank or humidification tank containing water or other liquids, which can humidify the gas while achieving cushioning.

[0051] It should be noted that the volume of the buffer 1 is not limited in this embodiment, and those skilled in the art can adjust it according to actual needs. In practical applications, the volume of the buffer 1 is usually 3mL-900mL. It is understood that compared with the soft rubber buffer 1, the hard rubber buffer 1 has less elasticity and a relatively fixed volume. Therefore, in order to improve the cushioning effect, the hard rubber buffer 1 has a larger external size, which will affect the portability of the regulator to some extent.

[0052] In practical applications, such as Figures 11 to 12 As shown, when the breathing ratio is 2:1, during inhalation, the pulse oxygen concentrator outputs oxygen. Without a regulator, the pulse oxygen output is short-lived and fast-flowing, forming an output waveform with a very high peak value, as shown below. Figure 11 As shown, the area enclosed by the outflow waveform, i.e., the shaded area of ​​the triangle, represents the volume of oxygen delivered. Since only the area where the outflow and inflow waveforms overlap can be utilized by the user, without a regulator, a significant portion of the oxygen, although delivered to the user's nasal cavity, is not utilized. With a regulator, the volume of delivered oxygen remains constant, but the output time becomes longer and the flow rate slower, resulting in an outflow waveform with a lower peak value, as shown... Figure 12As shown in the diagram, the area of ​​the overlap between the exhaust and intake waveforms increases, meaning more oxygen can be utilized by the user, thus reducing oxygen waste and improving oxygen utilization. Furthermore, the reduced oxygen flow rate, where the regulator softens the airflow, enhances user comfort.

[0053] It should be noted that the specific location of the regulator is not limited in the embodiments of this application. In one embodiment, the regulator can be integrated with the oxygen generating device, that is, the regulator is installed as a component of the oxygen generating device. Specifically, the oxygen generating device includes an outlet valve and an outlet arranged sequentially along the gas flow direction X. The outlet valve is used to control the gas flow rate, velocity, etc. The regulator can be placed at any position between the outlet valve and the outlet. In an optional embodiment, a buffer 1 is provided on the pipeline or channel connecting the outlet valve and the outlet. The buffer 1 can be integrated with the pipeline or channel, wherein the diameter of the buffer cavity 11 is larger than the diameter of the pipeline or channel.

[0054] In another embodiment, the oxygen inhalation device includes an air inlet, and the regulator can be installed as a separate accessory between the air outlet of the oxygen generator and the air inlet of the oxygen inhalation device. In another embodiment, the regulator can be integrated with the oxygen inhalation device, i.e., the regulator is installed as a component of the oxygen generator within the oxygen inhalation device.

[0055] In some optional embodiments of this application, the oxygen generating device includes an air outlet, and the oxygen inhalation device includes an air inlet; the buffer 1 includes an outer wall and a buffer cavity 11 formed by the outer wall, the outer wall being elastic; the buffer cavity 11 is connected to the air outlet and the air inlet respectively.

[0056] In this embodiment of the application, by setting a buffer chamber 11, which is connected to the air outlet and the air inlet respectively, the oxygen with short outlet time and fast flow rate can be converted into oxygen with long outlet time and slow flow rate through the buffer chamber 11, and continuously and stably delivered to the user.

[0057] In one embodiment, the buffer 1 is an elastic airbag. When the elastic airbag inflates, its volume increases, thereby reducing the gas flow rate. Specifically, as... Figure 5As shown, when the user inhales, pulsed oxygen is output from the outlet and temporarily stored in the elastic airbag. During this process, the elastic airbag expands, increasing its volume. The kinetic energy of the gas is converted into the elastic potential energy of the airbag, thus reducing the gas flow rate. As gas is continuously delivered to the user from the inlet, the gas volume gradually decreases. During this process, the elastic airbag gradually returns to its original shape, its volume gradually decreasing. The elastic potential energy of the airbag is converted into the kinetic energy of the gas, ensuring a continuous and stable delivery of the remaining gas to the user. In summary, the elastic airbag can transform oxygen with a short output time and high flow rate into oxygen with a long output time and slow flow rate, thereby alleviating irritation, improving oxygen utilization, and enhancing user comfort and therapeutic efficacy.

[0058] In some optional embodiments of this application, the buffer 1 is further provided with: a first interface 12 and a second interface 13; the first interface 12 and the second interface 13 are respectively disposed at both ends of the buffer 1 along the gas flow direction X and are both connected to the buffer chamber 11; the first interface 12 is connected to the air outlet so that the buffer chamber 11 is connected to the air outlet; the second interface 13 is connected to the air inlet so that the buffer chamber 11 is connected to the air inlet. In this way, due to the provision of the first interface 12 and the second interface 13, the connection between the oxygen generator, the oxygen inhalation device and the regulator can be realized through the connection between the first interface 12 and the air outlet and the second interface 13 and the air inlet, so that the gas can be smoothly delivered to the user in sequence through the oxygen generator, the regulator and the oxygen inhalation device.

[0059] In some optional embodiments of this application, the regulator further includes: a speed control valve 2; the speed control valve 2 is disposed between the buffer 1 and the air inlet and is connected to the buffer 1 and the air inlet respectively, and the speed control valve 2 is used to regulate the flow rate of gas into the air inlet.

[0060] In this embodiment of the application, by setting the speed regulating valve 2, the gas flow rate can be flexibly adjusted, thereby better matching the user's needs for oxygen inhalation comfort and improving the user's experience.

[0061] It should be noted that the speed control valve 2 can be a needle valve. A needle valve is a common type of fine-tuning valve, primarily used to regulate gas flow. A needle valve mainly consists of a valve body and a needle valve core. The valve body includes a channel, and the needle valve core is movably connected to the valve body. By rotating or pushing the needle valve core, the cross-sectional area of ​​the channel can be changed, thereby adjusting the gas flow rate. Furthermore, connectors, such as pagoda connectors, can be provided at both ends of the valve body along the extension direction of the channel, facilitating the quick connection of the buffer component 1, the oxygen supply device, and the speed control valve 2.

[0062] In some alternative embodiments of this application, such as Figures 6 to 10 As shown, the regulator also includes a limiting shell 3, which is fitted onto the buffer 1 to limit the expansion of the buffer 1.

[0063] In this embodiment, by providing a limiting shell 3, the expansion degree of the buffer 1 can be limited, avoiding the problem of reduced service life due to excessive deformation. Furthermore, since the buffer 1 is typically made of soft rubber, it is easily damaged during transportation or use; therefore, the limiting shell 3 also serves to protect the buffer 1.

[0064] It should be noted that the limiting shell 3 is typically made of hard plastic, which is not easily deformed and can better protect and limit the expansion of the buffer 1. It is understood that the shape of the limiting shell 3 should be similar to that of the buffer 1, and its size should be slightly larger than that of the buffer 1, allowing the buffer 1 to expand to a certain extent. This application does not limit the shape of the limiting shell 3 and the buffer 1; those skilled in the art can adjust them according to actual needs. In one embodiment, both the limiting shell 3 and the buffer 1 are spherical.

[0065] In some optional embodiments of this application, the limiting shell 3 is provided with multiple weight-reducing holes 31. By providing weight-reducing holes 31, the weight of the limiting shell 3 can be reduced, achieving lightweight adjustment and making the adjustment easy to carry. It should be noted that the multiple weight-reducing holes 31 can be evenly distributed on the limiting shell 3 so that the surface of the buffer 1 can be uniformly limited, effectively avoiding the problem of severe local deformation.

[0066] In summary, the oxygen supply system provided in this application has at least the following advantages:

[0067] In this embodiment, a regulator is installed between the oxygen generator and the oxygen inhalation device, and the regulator's buffer can reduce the gas flow rate. This effectively alleviates the irritation to the user's nasal cavity caused by the high gas flow rate, improving user comfort. Furthermore, it extends the gas output time, allowing more gas to be used by the user, thus improving oxygen utilization and treatment efficacy.
