Description

Technical Field

[0001] This application relates to the field of oxygen generation system technology, and in particular to a medical oxygen generation system and medical equipment. Background Technology

[0002] The medical central oxygen generation system, also known as the medical molecular sieve pressure swing adsorption (PSA) oxygen generation system, uses molecular sieves as adsorbents and ambient air as raw material through pressure swing adsorption. Under normal temperature and low pressure conditions, it utilizes the characteristic that the molecular sieve's adsorption capacity for nitrogen (adsorbate) in the air increases when pressurized and decreases when depressurized, forming a rapid cycle of pressurized adsorption and depressurized desorption. This allows oxygen and nitrogen in the air to be separated. Carbon dioxide, gaseous acids, and other gaseous oxides in the air are all highly polar substances and have difficulty passing through the molecular sieve, thus producing oxygen with a purity of over 93% v / v. During the oxygen generation process, the air raw material and the finished oxygen are purified and monitored at each stage to ensure the quality of the finished oxygen and effectively extend the service life of the molecular sieve.

[0003] The application of PSA oxygen generation technology has gained recognition in the medical field both domestically and internationally. As early as 1990, the United States included molecular sieve oxygen generation in the United States Pharmacopeia, and China issued the "General Technical Specification for Medical Molecular Sieve Oxygen Generation Equipment" (YYT0298-1998) in 1998. Currently, more than 2,000 hospitals nationwide use molecular sieve oxygen generation systems for oxygen supply. The safety, convenience, controllability, operational stability, and unparalleled ultra-low cost of the equipment have spurred the rapid development of central oxygen generation systems, leading to their acceptance and recognition by a wide range of medical institutions. They are gradually replacing cylinder oxygen and liquid oxygen, becoming the preferred oxygen source for large and medium-sized medical institutions and a key indicator of modern hospital management.

[0004] In existing oxygen production systems, the oxygen production mechanism is PSA oxygen production, which has a large energy consumption of air compressors. Summary of the Invention

[0005] Therefore, it is necessary to provide an oxygen generation system and medical equipment to address the above problems.

[0006] An oxygen generation system, comprising:

[0007] Several oxygen generating modules, each of which is configured to generate oxygen at a preset constant power;

[0008] The oxygen storage module is connected to each of the oxygen generating modules through multiple independent first oxygen delivery pipelines;

[0011] In one embodiment, the oxygen storage module includes a low-pressure oxygen storage tank, a high-pressure oxygen storage tank, and a booster pump; the low-pressure oxygen storage tank is connected to each of the oxygen generating modules through an independent first oxygen delivery pipeline; the high-pressure oxygen storage tank is connected to the low-pressure oxygen storage tank through a second oxygen delivery pipeline; and the booster pump is located on the second oxygen delivery pipeline.

[0012] In one embodiment, the control unit is communicatively connected to the booster pump; and the control unit is configured to control the booster pump to start in conjunction with each of the oxygen generating modules.

[0013] In one embodiment, there are multiple second oxygen delivery pipelines and multiple booster pumps; the high-pressure oxygen storage tank and the low-pressure oxygen storage tank are connected through independent second oxygen delivery pipelines, and each booster pump is set up in a one-to-one correspondence with the other booster pump.

[0014] The control unit is communicatively connected to all of the booster pumps; and the control unit is configured to selectively control each of the booster pumps to start individually or simultaneously, in conjunction with a corresponding number of the oxygen generating modules.

[0015] In one embodiment, the second detection element is communicatively connected to all of the booster pumps; the second detection element is further configured to determine whether each of the booster pumps is turned on within a preset period; the control element is configured to control each oxygen generating module and each of the booster pumps to be turned on an equal number of times within a preset period based on the detection result of the second detection element.

[0016] In one embodiment, each oxygen generation module includes an air compressor, a refrigerated dryer, an air tank, and an adsorption tower. The air compressor, the refrigerated dryer, the air tank, and the adsorption tower are connected in sequence via pipelines. The adsorption tower is connected to the oxygen storage module via a corresponding first oxygen delivery pipeline.

[0017] In one embodiment, the oxygen generation module further includes an air detector connected to the air inlet of the adsorption tower.

[0018] In one embodiment, the oxygen generation module further includes a switching valve connected to a pipeline between the refrigerated dryer and the air tank.

[0019] A medical device comprising an oxygen generation system as described in the foregoing embodiments.

[0020] The aforementioned medical oxygen generation system and equipment include an oxygen generation system comprising several oxygen generation modules, an oxygen storage module, and a control module. Each oxygen generation module is configured to generate oxygen at a preset constant power. The oxygen storage module is connected to each oxygen generation module via multiple independent first oxygen delivery pipelines. The control module is communicatively connected to all oxygen generation modules. The control module includes a control element and a first detection element, which is configured to determine the oxygen consumption at the output of the oxygen storage module. The control element is configured to selectively control each oxygen generation module to operate individually or simultaneously based on the oxygen consumption.

[0021] Understandably, in the specific use of the oxygen generation system, the operation of any one of the oxygen generation modules can be controlled individually, or multiple oxygen generation modules can be controlled simultaneously, so that each oxygen generation module produces oxygen at a constant preset power, and the produced oxygen is transported to the oxygen storage module for storage through the corresponding first oxygen delivery pipeline. The oxygen storage module is also connected to the general oxygen equipment and supplies oxygen to the oxygen-using equipment.

[0022] More specifically, users need to control the number of oxygen generating modules in operation based on the actual oxygen consumption of the oxygen-using equipment, so as to ensure that the total amount of oxygen produced by all operating oxygen generating modules is not less than the actual oxygen consumption of the oxygen-using equipment.

[0023] For example, each oxygen generating module is defined to operate at a constant preset power of producing 10L of oxygen per unit time. If the actual oxygen consumption of the oxygen-using equipment is 10L per unit time, only one of the oxygen generating modules needs to be controlled individually to meet the oxygen supply needs of the equipment. Conversely, if the actual oxygen consumption of the oxygen-using equipment is greater than 10L but not greater than 20L per unit time, two oxygen generating modules need to be controlled simultaneously to meet the oxygen supply needs of the equipment. Similarly, when the actual oxygen consumption of the oxygen-using equipment is greater than 20L but not greater than 30L per unit time, three oxygen generating modules need to be controlled simultaneously. In this way, the number of oxygen generating modules in operation can be flexibly adjusted according to the specific value of oxygen consumption to ensure that the total amount of oxygen produced matches the amount of oxygen consumed.

[0024] Based on the above, in the specific use of the oxygen generation system, the user can control the operation of different oxygen generation modules between two consecutive uses of the system. That is, in two consecutive uses, an oxygen generation module that has been used in the previous use will not be used in the next use, while the subsequent use will control the operation of other oxygen generation modules. In this way, this application can effectively prevent some oxygen generation modules from excessively wearing out due to long-term continuous operation, thereby balancing the workload of each oxygen generation module and extending the overall service life of the entire oxygen generation system.

[0025] For ease of understanding, for example, the oxygen generation system is defined to include three oxygen generation modules: A, B, and C. If module A is controlled to run when the oxygen generation system is used for the first time, module B can be selected to run when the oxygen generation system is used for the second time; correspondingly, module C is selected to run when the oxygen generation system is used for the third time, and so on, so that each module can get sufficient rest and maintenance intervals.

[0026] Furthermore, when an oxygen generating module malfunctions and requires maintenance, the control module can immediately switch to other normal oxygen generating modules to ensure a continuous and stable oxygen supply for the entire oxygen generating system, thereby improving the system's reliability and fault tolerance.

[0027] In other words, by setting up multiple oxygen generation modules, this application enables flexible control strategies, optimizes energy consumption, and avoids the problem of low efficiency of a single air compressor in traditional oxygen generation systems under low load. Furthermore, by operating in a distributed manner, it further enhances the safety and stability of the system, better adapting to the actual needs of fluctuating oxygen consumption in hospitals and other similar locations.

[0028] It should also be noted that when the total number of oxygen generating modules that need to be operated during two consecutive uses of the oxygen generating system exceeds the number of oxygen generating modules that the oxygen generating system has, the control module can select the oxygen generating modules that were not operated during the previous use to start operation according to the preset rotation logic.

[0029] For ease of understanding, let's define an oxygen generation system as comprising three modules: A, B, and C. When the system is used for the first time, two modules (e.g., A and B) need to be running. When the system is used a second time, both modules still need to be running. The control module will prioritize module C and then select from A and B the module with the shorter previous usage time or the shorter cumulative running time. For example, assuming module A ran for 1 hour and module B ran for 1.5 hours previously, modules C and A will be selected to balance the total running time of each module as much as possible.

[0030] If all oxygen generating modules have already run for an equal amount of time in the previous use, they will be selected sequentially according to their module numbers or a preset priority order. That is, modules C and A will be selected, and in the next (third) use of the oxygen generating system where two modules need to be run, modules B and C will be controlled. This ensures that the usage frequency and cumulative operating time of each module are roughly equivalent, thereby further optimizing the load distribution of each oxygen generating module and extending its overall service life.

[0039] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application 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 application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0040] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0041] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0042] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0043] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0044] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0045] The medical central oxygen generation system, also known as the medical molecular sieve pressure swing adsorption (PSA) oxygen generation system, uses molecular sieves as adsorbents and ambient air as raw material through pressure swing adsorption. Under normal temperature and low pressure conditions, it utilizes the characteristic that the molecular sieve's adsorption capacity for nitrogen (adsorbate) in the air increases when pressurized and decreases when depressurized, forming a rapid cycle of pressurized adsorption and depressurized desorption.

During the oxygen generation process, the air raw material and the finished oxygen are purified and monitored at each stage to ensure the quality of the finished oxygen and effectively extend the service life of the molecular sieve.

[0046] The application of PSA oxygen generation technology has gained recognition in the medical field both domestically and internationally. As early as 1990, the United States included molecular sieve oxygen generation in the United States Pharmacopeia, and China issued the "General Technical Specification for Medical Molecular Sieve Oxygen Generation Equipment" (YYT0298-1998) in 1998. Currently, more than 2,000 hospitals nationwide use molecular sieve oxygen generation systems for oxygen supply.

They are gradually replacing cylinder oxygen and liquid oxygen, becoming the preferred oxygen source for large and medium-sized medical institutions and a key hardware indicator of modern hospital management.

[0047] In existing oxygen production systems, the oxygen production mechanism is PSA oxygen production, and its air compressor 101 has a large energy consumption.

[0048] Therefore, to resolve the aforementioned technical issues, please refer to [link / reference needed]. Figures 1 to 3 This application provides an oxygen generation system 100 in one or more embodiments. By setting multiple oxygen generation modules 10, a flexible control strategy can be implemented to optimize energy consumption and avoid the problem of low efficiency of a single air compressor 101 in traditional oxygen generation systems 100 under low load. Furthermore, by operating in a distributed manner, the safety and stability of the system operation can be further improved to better adapt to the actual needs of fluctuating oxygen consumption in places such as hospitals.

[0049] Specifically, please see Figure 1 and Figure 2 The oxygen generation system 100 includes several oxygen generation modules 10, an oxygen storage module 11, and a control module 12. Each oxygen generation module 10 is configured to generate oxygen at a preset constant power. The oxygen storage module 11 is connected to each oxygen generation module 10 through multiple independent first oxygen delivery pipelines. The control module 12 is communicatively connected to all oxygen generation modules 10. The control module 12 includes a control element 121 and a first detection element 122. The first detection element 122 is configured to determine the oxygen consumption at the output of the oxygen storage module 11. The control element 121 is configured to selectively control each oxygen generation module 10 to operate individually or simultaneously based on the oxygen consumption.

[0050] It is understandable that, in the specific use of the oxygen generation system 100, the operation of any one of the oxygen generation modules 10 can be controlled individually, or the operation of multiple oxygen generation modules 10 can be controlled synchronously, so that each oxygen generation module 10 produces oxygen at a constant preset power, and the produced oxygen is transported to the oxygen storage module 11 for storage through the corresponding first oxygen delivery pipeline. The oxygen storage module 11 is connected to a general oxygen supply device and supplies oxygen to the oxygen-using equipment.

[0051] More specifically, users need to control the number of oxygen generating modules 10 in operation according to the actual oxygen consumption of the oxygen-using equipment, so as to ensure that the total amount of oxygen generated by all operating oxygen generating modules 10 is not less than the actual oxygen consumption of the oxygen-using equipment.

[0052] For example, each oxygen generating module 10 is defined to operate at a constant preset power of producing 10L of oxygen per unit time. If the actual oxygen consumption of the oxygen-using equipment is 10L per unit time, only one of the oxygen generating modules 10 needs to be controlled individually to meet the oxygen supply needs of the oxygen-using equipment. Correspondingly, if the actual oxygen consumption of the oxygen-using equipment is greater than 10L but not greater than 20L per unit time, two oxygen generating modules 10 need to be controlled simultaneously to meet the oxygen supply needs of the oxygen-using equipment. Similarly, when the actual oxygen consumption of the oxygen-using equipment is greater than 20L but not greater than 30L per unit time, three oxygen generating modules 10 need to be controlled simultaneously. In this way, the number of oxygen generating modules 10 in operation can be flexibly adjusted according to the specific value of oxygen consumption to ensure that the total amount of oxygen produced matches the amount of oxygen consumed.

[0053] Based on the above, in the specific use of the oxygen generation system 100, the user can control the operation of different oxygen generation modules 10 during two consecutive uses of the oxygen generation system 100. That is, during two consecutive uses of the oxygen generation system 100, an oxygen generation module 10 that has been used in the previous use will not be used in the next use, and the user can control the operation of other oxygen generation modules 10 during the next use. In this way, this application can effectively prevent some oxygen generation modules 10 from excessively wearing out due to long-term continuous operation, thereby balancing the workload of each oxygen generation module 10 and extending the overall service life of the entire oxygen generation system 100.

[0054] For ease of understanding, for example, the oxygen generation system 100 is defined to include three oxygen generation modules 10: A, B, and C. If module A is controlled to run when the oxygen generation system 100 is used for the first time, module B can be selected to run when the oxygen generation system 100 is used for the second time. Correspondingly, module C is selected to run when the oxygen generation system 100 is used for the third time, and so on, so that each module can get sufficient rest and maintenance intervals.

[0055] Furthermore, when one of the oxygen generating modules 10 malfunctions and requires maintenance, the control module 12 can immediately switch to other normal oxygen generating modules 10 to ensure the continuous and stable oxygen supply of the entire oxygen generating system 100, thereby improving the system's reliability and fault tolerance.

[0056] In other words, by setting up multiple oxygen generation modules 10, this application can achieve flexible control strategies, optimize energy consumption, and avoid the problem of low efficiency of a single air compressor 101 in a traditional oxygen generation system 100 under low load. Furthermore, by operating in a distributed manner, it can further improve the safety and stability of the system operation, better adapting to the actual needs of fluctuating oxygen consumption in places such as hospitals.

[0057] It should also be noted that when the total number of oxygen generating modules 10 that need to be operated during two consecutive uses of the oxygen generating system 100 exceeds the number of oxygen generating modules 10 that the oxygen generating system 100 has, the control module 12 can select the oxygen generating modules 10 that were not operated during the previous use to be put into operation according to the preset rotation logic.

[0058] For ease of understanding, let's define the oxygen generation system 100 as comprising three oxygen generation modules 10: A, B, and C. When the oxygen generation system 100 is used for the first time, two modules (e.g., A and B) need to be running. When the oxygen generation system 100 is used a second time, both modules still need to be running. In this case, the control module 12 will prioritize module C and select from A and B the module with the shorter previous usage time or the shorter cumulative running time. For example, assuming module A ran for 1 hour and module B ran for 1.5 hours previously, modules C and A will be selected to balance the total running time of each module as much as possible.

[0059] If all oxygen generating modules 10 have already run for an equal amount of time in the previous use, they are selected sequentially according to their module numbers or a preset priority order. That is, modules C and A are selected, and in the next (third) use of the oxygen generating system 100 where two modules need to be run, modules B and C are controlled. This ensures that the usage frequency and cumulative operating time of each module are roughly equivalent, thereby further optimizing the load distribution of each oxygen generating module 10 and extending its overall service life.

[0060] In some embodiments, see Figure 1 and Figure 2 The control module 12 includes a second detection element 123, which is configured to determine whether each oxygen generating module 10 is turned on within a preset cycle. The control element 121 is configured to control each oxygen generating module 10 to be turned on an equal number of times within a preset cycle based on the detection result of the second detection element 123.

[0061] It is understood that in this application, the preset cycle refers to a certain preset time or a certain number of times the oxygen generation system 100 is used.

[0062] Based on this, the control module 12 uses a second detection element 123 to monitor and record the activation status of each oxygen-generating module 10 in real time within a preset period, including data such as the number of activations, the duration of each activation, and the cumulative activation duration. After receiving the activation status of each oxygen-generating module 10 within the preset period from the second detection element 123, the control unit 121 statistically analyzes the activation count of each oxygen-generating module 10. If it is found that some oxygen-generating modules 10 have significantly more activations than others within the preset period, the control unit 121 will prioritize the operation of oxygen-generating modules 10 with fewer activations during subsequent use of the oxygen-generating system 100 within that preset period, and appropriately reduce the activation frequency of modules with more activations, until the end of the preset period, so that the activation counts of all oxygen-generating modules 10 are equal. Thus, by setting the second detection element 123, this application can achieve fine control to ensure that the workload of each oxygen generation module 10 is evenly distributed, and avoid accelerated aging or increased risk of failure caused by long-term high-frequency operation of individual modules, thereby effectively improving the economy and durability of the oxygen generation system 100.

[0063] In some embodiments, see Figure 1 The oxygen storage module 11 includes a low-pressure oxygen storage tank 111, a high-pressure oxygen storage tank 112, and a booster pump 113. The low-pressure oxygen storage tank 111 is connected to each oxygen generation module 10 via an independent first oxygen delivery pipeline. The high-pressure oxygen storage tank 112 is connected to the low-pressure oxygen storage tank 111 via a second oxygen delivery pipeline. The booster pump 113 is located on the second oxygen delivery pipeline.

[0064] Understandably, in the specific use of the oxygen generation system 100, the operation of any one of the oxygen generation modules 10 can be controlled individually, or multiple oxygen generation modules 10 can be controlled simultaneously, so that each oxygen generation module 10 produces oxygen at a constant preset power. The produced oxygen is then transported to the low-pressure oxygen storage tank 111 for storage through the corresponding first oxygen delivery pipeline. When the oxygen pressure or capacity in the low-pressure oxygen storage tank 111 reaches a preset threshold, the booster pump 113 is activated, pressurizing the oxygen in the low-pressure oxygen storage tank 111 and then transporting it to the high-pressure oxygen storage tank 112 for high-pressure storage through the second oxygen delivery pipeline. Furthermore, the oxygen storage module 11 is connected to a general oxygen supply device and supplies oxygen to the oxygen-using equipment.

[0065] This application enables graded oxygen storage by setting up a low-pressure oxygen storage tank 111 and a high-pressure oxygen storage tank 112. This avoids waste caused by the lack of oxygen storage during periods of low oxygen demand, and the high-pressure oxygen storage tank 112 ensures that sufficient oxygen can be quickly provided when oxygen demand surges (such as in emergency hospital rescue situations), thus ensuring the continuity and stability of oxygen supply.

[0066] Further, please see Figure 1 The control unit 121 is communicatively connected to the booster pump 113. The control unit 121 is configured to control the booster pump 113 to be turned on in conjunction with each oxygen generation module 10.

[0067] In some embodiments, please refer to Figure 1 and Figure 2 There are multiple second oxygen delivery pipelines and booster pumps 113. High-pressure oxygen storage tank 112 and low-pressure oxygen storage tank 111 are connected via independent second oxygen delivery pipelines, and each booster pump 113 is configured in a one-to-one correspondence. Control unit 121 is communicatively connected to all booster pumps 113. Control unit 121 is configured to selectively control each booster pump 113 to operate individually or simultaneously, in conjunction with the corresponding number of oxygen generating modules 10.

[0068] Understandably, during the specific use of the oxygen generation system 100, when the control module 12 determines that N oxygen generation modules 10 (N being a positive integer) need to be activated based on the oxygen consumption, the control unit 121 will correspondingly control the N oxygen generation modules 10 and the booster pump 113 to be activated synchronously. In this way, each activated booster pump 113 can form a corresponding cooperative relationship with the operating oxygen generation module 10, so as to timely and efficiently boost and deliver the oxygen generated by the oxygen generation module 10 and initially stored in the low-pressure oxygen storage tank 111 to the high-pressure oxygen storage tank 112 for use by the oxygen-consuming equipment.

[0069] Further, please see Figure 1The second detection element 123 is communicatively connected to all booster pumps 113. The second detection element 123 is also configured to determine whether each booster pump 113 is turned on within a preset cycle. The control element 121 is configured to control each oxygen generating module 10 and each booster pump 113 to be turned on an equal number of times within a preset cycle based on the detection result of the second detection element 123.

[0070] Understandably, during the actual use of the oxygen generation system 100, the second detection element 123, while monitoring and recording the activation status of each oxygen generation module 10 within a preset period, can also monitor the activation status of all booster pumps 113, including data such as the number of times each booster pump 113 is activated, the duration of a single run, and the cumulative running time. After receiving the activation status of each oxygen generation module 10 and booster pump 113 within the preset period from the second detection element 123 in real time, the control element 121 will statistically analyze the number of times each oxygen generation module 10 and booster pump 113 is activated to ensure that the number of times each oxygen generation module 10 is activated and the number of times each booster pump 113 is activated remain at the same level within the same preset period. In this way, by binding and balancing the operation frequency of the oxygen generating module 10 and the booster pump 113, it is possible to avoid excessive wear and tear on the booster pump 113 due to long-term pairing with the oxygen generating module 10 operating at high frequency, or rusting and aging of the booster pump 113 due to long-term idleness; and to ensure that the workload of each oxygen generating module 10 and each booster pump 113 is evenly distributed, avoiding accelerated aging or increased risk of failure caused by long-term high-frequency operation of individual modules, thereby effectively improving the economy and durability of the oxygen generating system 100.

[0071] In some embodiments, see Figure 1 and Figure 3 Each oxygen generation module 10 includes an air compressor 101, a refrigerated dryer 102, an air tank 103, and an adsorption tower 104. The air compressor 101, the refrigerated dryer 102, the air tank 103, and the adsorption tower 104 are connected sequentially by pipelines. The adsorption tower 104 is connected to the low-pressure oxygen storage tank 111 through a corresponding first oxygen delivery pipeline.

[0072] Understandably, in the specific operation of the oxygen generation system 100, firstly, the air compressor 101 draws in air from the external environment and compresses it to provide the high-pressure air source required for subsequent processes. Secondly, the compressed air is sent to the refrigerated dryer 102, which removes moisture from the air through cooling to prevent moisture from entering subsequent equipment and damaging core components such as molecular sieves, while also reducing the impact on oxygen purity. Thirdly, the compressed air dried by the refrigerated dryer 102 is sent to the air tank 103, which acts as a buffer and pressure stabilizer to ensure stable air pressure entering the adsorption tower 104, preventing pressure fluctuations from adversely affecting the adsorption performance of the molecular sieves within the adsorption tower 104. When the pressure in the air tank 103 reaches the set value, the dried compressed air enters the adsorption tower 104. The adsorption tower 104 is filled with high-performance molecular sieves, which utilize the principle of selective adsorption to efficiently adsorb impurities such as nitrogen and carbon dioxide from the air, thereby separating oxygen. The separated oxygen is then transported through the first oxygen pipeline to the low-pressure oxygen storage tank 111 for temporary storage for later use.

[0073] In some embodiments, see Figure 1 and Figure 3 The oxygen generation module also includes an air detector, which is connected to the air inlet of the adsorption tower.

[0074] Understandably, air detectors can monitor the air entering the adsorption tower in real time, and the monitoring parameters may include, but are not limited to, air temperature, humidity, pressure, and the concentration of some key pollutants (such as oil content, particulate matter concentration, etc.).

[0075] Specifically, during the actual use of the oxygen generation system 100, when the air detector detects that the air parameters entering the adsorption tower exceed the preset safety range—for example, excessive humidity may cause the molecular sieve to become damp and affect adsorption efficiency, or excessive oil content may contaminate the molecular sieve—the air detector will promptly send an abnormal signal back to the control module 12. Upon receiving such an abnormal signal, the control module 12 can issue an alarm according to a preset program, reminding the operator to check and handle the situation, thereby ensuring the long-term stable operation of the oxygen generator and the quality and safety of the produced oxygen.

[0076] In some embodiments, see Figure 1 and Figure 3 The oxygen generation module also includes a switching valve, which is connected to the pipeline between the refrigerated dryer 102 and the air tank 103.

[0077] It is understandable that the switching valve can control the opening and closing of the pipeline between the refrigerated dryer 102 and the air tank 103 according to the operating status of the oxygen generation system 100, so as to ensure the safety and stability of the oxygen generation system 100 under specific operating conditions.

[0078] This application also provides a medical device in one or more embodiments, the medical device including the oxygen generation system 100 as described in the foregoing embodiments.

[0079] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0080] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
