Description

Technical Field

[0001] The present invention relates to the technical field of oxygen concentrators, and in particular to a medical oxygen concentrator. Background Art

[0002] Medical oxygen concentrators are designed for people who require oxygen therapy and oxygen health care, such as those with respiratory conditions such as pneumonia, bronchitis, chronic tracheitis, viral respiratory infections, asthma, emphysema, cor pulmonale, and silicosis. They also address high-altitude hypoxia symptoms such as high-altitude pulmonary edema, acute mountain sickness, chronic mountain sickness, high-altitude coma, and high-altitude hypoxia. People at risk of hypoxia include the elderly, pregnant women, students engaged in long-term mental work, company employees, and government officials; those who work underground or in confined spaces for extended periods; and those experiencing oxygen deprivation due to excessive exercise and fatigue. Medical oxygen concentrators utilize the pressure swing adsorption (PSA) principle for oxygen production, eliminating the need for replacement consumables and maintaining low operating costs, making them an ideal choice for home oxygen therapy.

[0037] The present invention provides a medical oxygen concentrator.

[0038] refer to Figures 1 to 9 In one embodiment of the present invention, the medical oxygen concentrator includes: an upper housing 11, a base 12, an air pump 2, a molecular sieve assembly 3, an atomizing device 4, and a piping system 5. An installation space is formed between the upper housing 11 and the base 12, and the upper housing 11 is connected to the base 12. The air pump 2 is disposed in the installation space, with the bottom of the air pump 2 connected to the base 12. A heat sink is provided on one side of the air pump 2, and the nozzle of the air inlet pipe 22 of the air pump 2 is exposed on the side wall of the upper housing 11. The molecular sieve assembly 3 is disposed in the installation space and is provided with an air inlet port 31, which is in communication with the air pump 2. The atomizing device 4 is mounted on the upper housing 11 and partially exposed outside the upper housing 11. The piping system 5 is disposed in the installation space and is arranged near the heat sink. The piping system 5 is connected to the air pump 2, the molecular sieve assembly 3, and the atomizing device 4.

[0039] The technical solution of the present invention achieves the effect of cooling the pipeline by placing the pipeline system 5 close to the heat dissipation device so that the temperature in the pipeline is rapidly reduced. Specifically, the heat dissipation device is installed on one side of the air pump 2. While dissipating heat for the pipeline, it also cools the gas just compressed by the air pump 2, further improving the cooling effect of the medical oxygen concentrator and meeting the molecular sieve component 3's demand for lower temperature gas. In addition, the pipeline system 5 is connected to the air pump 2, the molecular sieve component 3 and the atomizing device 4 respectively, so that the entire medical oxygen concentrator can not only meet the requirements of compressing gas and adsorbing gas but also realize the atomization function. Among them, the nozzle of the air inlet pipe 22 of the air pump 2 is exposed on the side wall of the upper shell 11. By directly sucking air from the outside of the upper shell 11 and transporting it to the molecular sieve component 3 connected to the air pump 2 through the air pump 2, the air is adsorbed in the molecular sieve component 3, thereby obtaining high-purity oxygen.

[0040] refer to Figure 3 Specifically, the pipeline system 5 includes a four-way valve 51, which has a first interface 511, a second interface 512, a third interface 513 and a fourth interface 514; the molecular sieve component 3 is also provided with a first gas outlet interface 32; the first interface 511 is connected to the air pump 2, the second interface 512 is connected to the atomization device 4, the third interface 513 is connected to the air inlet interface 31, and the fourth interface 514 is connected to the first gas outlet interface 32.

[0041] The configuration of the four-way valve 51 enables the oxygen concentrator to have at least three conduction modes. The first interface 511 and the second interface 512 are connected to realize the atomization function of the atomizing device 4. The gas is compressed by the air pump 2 and transported from the first interface 511 to the second interface 512. Finally, the high-pressure gas is released through the atomizing device 4 to realize the atomization function. The first interface 511 and the third interface are connected to realize the intake of the molecular sieve assembly 3. The gas is transported from the first interface 511 to the third interface 513 after passing through the air pump 2, and then enters the molecular sieve assembly 3 from the air inlet interface 31 in the molecular sieve assembly 3 for gas adsorption. The second interface 512 and the fourth interface 514 are connected to realize the replenishment of oxygen in the atomizing device 4. When the pressure provided by the air pump 2 is insufficient or the user needs more oxygen, the fourth interface 514 can be connected. The pipeline corresponding to the fourth interface 514 is connected to the first outlet interface 32, and the oxygen prepared in the molecular sieve assembly 3 can be transported to the pipeline system 5 to replenish the oxygen content.

[0042] refer to Figure 4 and Figure 5The molecular sieve assembly 3 includes a molecular adsorber 34, a first mounting end cap 35, an air inlet valve assembly 36, a second mounting end cap 37, and an oxygen storage device 38. The molecular adsorber 34 is provided with an adsorption channel; the first mounting end cap 35 is provided with an air inlet and an air inlet channel that are interconnected, and the air inlet channel is connected to the adsorption channel, and the first mounting end cap 35 is provided on one side of the adsorption channel; the air inlet valve assembly 36 is provided on the air inlet interface 31; the second mounting end cap 37 is provided with a second air outlet interface 33 and an air outlet channel that are interconnected, and the air outlet channel is connected to the adsorption channel, and the second mounting end cap 37 is provided on the other side of the adsorption channel; the oxygen storage device 38 is hollow and is connected to the second air outlet. By using the air intake valve assembly 36, the controlled absorption and compression is transported from the air intake interface 31 through the air intake channel to the first mounting end cap 35, and other gases in the air are adsorbed through the adsorption channel of the molecular adsorber 34. The oxygen reaches the oxygen storage device 38 through the air outlet channel and the air outlet. The oxygen storage device 38 temporarily stores the oxygen. In this way, a high concentration of oxygen is obtained without the need for additional pipelines, reducing the possibility of gas leakage. Furthermore, a first mounting end cap 35 is provided on one side of the adsorption channel. A second mounting end cap 37 is provided on the other side. In this way, the first mounting end cap 35 and the second mounting end cap 37 only need to be covered from both sides of the adsorption channel to achieve assembly, which simplifies the entire assembly process and improves production efficiency.

[0043] The molecular adsorber 34 includes a first orifice plate 341, a second orifice plate 343, and an elastic member 342, which are arranged in the adsorption channel. The first orifice plate 341 is arranged near the inlet channel, the second orifice plate 343 is arranged near the outlet channel, and the elastic member 342 is arranged between the second orifice plate 343 and the second mounting end cap 37. In this embodiment, the gas flows from the position of the first orifice plate 341 to the position of the second orifice plate 343. Specifically, a molecular sieve is filled between the first orifice plate 341 and the second orifice plate 343. After the air flows through the molecular sieve, a higher concentration of oxygen is obtained. It should be noted that the elastic member 342 is arranged between the second orifice plate 343 and the second end cap. The molecular sieve moves upward after being pushed by the gas. However, the arrangement of the elastic member 342 squeezes the molecular sieve, which ultimately causes the spacing between the molecular sieves to further decrease. In this way, the molecular sieve assembly 3 has a better adsorption capacity, that is, the concentration of oxygen obtained is also higher.

[0044] The oxygen storage device 38 is provided with a second air outlet interface 33, one end of the second air outlet interface 33 is connected to the interior of the oxygen storage device 38, and the other end of the second air outlet interface 33 is provided with a pressure regulating valve 39. Obviously, the setting of the pressure regulating valve 39 can adjust the pressure of the oxygen output so that the user can inhale oxygen at the most suitable pressure. Furthermore, the oxygen storage device 38 is provided with a first air outlet interface 32, one end of the first air outlet interface 32 is connected to the interior of the oxygen storage device 38, and the other end of the first air outlet interface 32 is used to connect to the nebulizer. That is, the oxygen in the oxygen storage device 38 can be directly drawn out and used for other medical devices such as the nebulizer.

[0045] In one embodiment, the adsorption channel includes an oxygen production channel and a nitrogen absorption channel arranged in parallel; the air inlet channel includes a first air inlet channel and a second air inlet channel, and the air outlet channel includes a first air outlet channel and a second air outlet channel; the first air inlet channel and the second air inlet channel are both connected to the air inlet interface 31, the first air outlet channel and the second air outlet channel are both connected to the air outlet, the first air inlet channel and the first air outlet channel are both connected to the oxygen production channel, and the second air inlet channel and the second air outlet channel are both connected to the nitrogen absorption channel. Specifically, the air inlet valve assembly 36 includes a rotary valve, which is provided on the air inlet interface 31 and distributes the gas to be adsorbed to the oxygen production channel and the nitrogen absorption channel respectively.

[0046] The second air outlet interface 33 is used to directly output oxygen for use by the user. The medical oxygen concentrator also includes a humidification cup 6, which is arranged in the installation space. The piping system 5 also includes an oxygen outlet pipe, which connects the second air outlet interface 33 and the humidification cup 6. Oxygen is delivered to the user through the oxygen outlet pipe and the humidification cup 6. It should be understood that the oxygen prepared after the air passes through the molecular sieve component 3 will lack moisture and be relatively dry. If the user directly inhales it, the nasal mucosa passage will become dry, thereby affecting the user's oxygen inhalation experience. Oxygen will pass through the humidification cup 6 before being inhaled into the user's lungs. The oxygen humidified by the humidification cup 6 can increase the water content in the oxygen, so that the user's nasal cavity can remain moist, which is also conducive to improving the user's oxygen inhalation comfort.

[0047] refer to Figure 6The humidification cup 6 includes a cover assembly 61, a cup body 62, and a pressure relief assembly 63. The cover assembly 61 is detachably connected to the cup body 62. The cover assembly 61 and the cup body 62 cooperate to form a receiving cavity. One of the cup body 62 and the cover assembly 61 is provided with an air inlet nozzle, and the other is provided with an air outlet nozzle connected to the receiving cavity. The inner wall of the one provided with the air inlet nozzle is also provided with an air guide channel, and the air inlet nozzle is connected to the air guide channel, and the air guide channel is connected to the receiving cavity. One of the cup body 62 and the cover assembly 61 is provided with a pressure relief hole, and the pressure relief assembly 63 is installed in the pressure relief hole to control the opening and closing of the pressure relief hole. The humidification cup 6 is suitable for humidifying oxygen during oxygen therapy and oxygen health care to prevent damage to the nasal mucosa caused by dry oxygen during long-term oxygen inhalation. At the same time, the humidification cup 6 has a pressure unloading function, which prevents the pipe from bursting when the oxygen inhalation end is blocked. The appearance of the humidification cup 6 is consistent with that of the machine, ensuring the integrity of the appearance of the entire machine.

[0048] The oxygen outlet pipe is provided with a bend 521, and the bend 521 is provided in the installation space. The most direct effect of the provision of the bend 521 is to extend the length of the path through which oxygen flows. The longer the path through which oxygen flows, the slower the flow rate of oxygen will be, and the air pressure will gradually decrease. The lower the air pressure, the smaller the noise emitted by the gas flow. The reduction in noise is beneficial to the user experience. For patients, the quieter the environment, the more conducive it is to the patient's recovery, so the reduction in noise is also of great help to patients. Furthermore, since the path through which oxygen flows becomes longer and has a curved bend 521, and since the bend 521 has the physical characteristics of a corner, it is easy for stains, debris, and especially bacteria to remain and accumulate. As a medical oxygen concentrator, it is necessary to prevent bacteria from causing secondary damage to the patient's lungs. In this embodiment, a bacterial filter 522 is provided for the bend 521. After the prepared oxygen passes through the oxygen outlet pipe, it will inevitably flow through the bacterial filter 522. The bacterial filter 522 filters out the bacteria present in the oxygen before flowing into the user's lungs. This avoids secondary damage to the user's lungs by the user's oxygen concentrator, thereby improving the safety and practicality of the medical oxygen concentrator. In addition, it should be noted that the bacterial filter 522 is replaceable and is installed in the oxygen outlet pipe in a detachable manner. The bacterial filter 522 needs to be replaced periodically to further ensure the safety of the user. The oxygen outlet pipe is also provided with a one-way valve 523, which is arranged near the oxygen outlet port 524 of the oxygen outlet pipe. In this way, when the oxygen concentrator stops working, the one-way valve 523 can effectively prevent external air or water vapor in the humidification cup 6 from flowing back into the pipeline system 5, thereby preventing it from affecting the operation and life of other equipment such as the molecular sieve component 3 and the atomizer 4 connected to the pipeline system 5.

[0049] Furthermore, in order to accurately control the flow of gas in the pipeline system 5, the pipeline system 5 also includes a first flow valve 531 and a second flow valve 532. Specifically, the first flow valve 531 is provided in the pipeline connecting the fourth interface 514 and the first gas outlet interface 32, and is used to control the replenishment rate of oxygen coming out of the first gas outlet interface 32; the second flow valve 532 is provided in the oxygen outlet pipe, and is used to control the oxygen outlet rate of the second gas outlet interface 33. The user can adjust the flow of the first flow valve 531 and the second flow valve 532 through an external remote control or button so that the medical oxygen concentrator can supply oxygen to the patient at the oxygen flow rate that is most suitable for the patient. In addition, it should be noted that the first flow valve 531 and the second flow valve 532 not only control the flow but also have a monitoring function.

[0050] In a medical oxygen concentrator, the oxygen concentration needs to be monitored in real time. Only when the patient can obtain sufficient oxygen in a timely manner can the oxygen concentrator help the patient maintain a stable respiratory system. In one embodiment, the piping system 5 also includes a concentration detection device 54, which is located in the installation space and is connected to the oxygen outlet pipe. Before the oxygen is about to flow from the oxygen outlet pipe to the user, it will pass through the concentration detection device 54. The concentration detection device 54 can detect the concentration of oxygen coming out of the molecular sieve assembly 3 in real time and display it. If the concentration is insufficient, the oxygen production rate of the medical oxygen concentrator needs to be adjusted.

[0051] The medical oxygen concentrator also includes a soundproof enclosure 13, which is disposed inside the base 12 and forms a soundproof space between the enclosure and the base 12. The air pump 2 is disposed within the soundproof space, and the molecular sieve assembly 3 is mounted on top of the soundproof enclosure 13. The soundproof enclosure 13 absorbs the noise generated by the air pump 2 when compressing air within the soundproof space, thereby enhancing the user experience. In one embodiment, the heat dissipation device is configured as a fan 21. A heat dissipation opening 131 is defined on one side of the soundproof enclosure 13, and the fan 21 is disposed within the heat dissipation opening 131. The sidewall of the base 12 is provided with heat dissipation holes 121. The provision of the fan 21 creates an air flow path within the oxygen concentrator, enabling rapid heat exchange between the heat generated by the air pump 2 and the low-temperature external air, thereby achieving the cooling function of the medical oxygen concentrator.

[0052] Furthermore, the medical oxygen concentrator includes a display panel assembly 71; the top of the upper housing 11 is provided with a clearance hole, and the display panel assembly 71 is mounted within the clearance hole. Specifically, the display panel assembly 71 comprises, from top to bottom, a transparent cover plate 711, an electrical control unit 712, and a fixing ring 713. The electrical control unit 712 is fixedly connected to the upper housing 11 through the reinforcement of the fixing ring 713. The transparent cover plate 711 covers the top of the electrical control unit 712, allowing the user to intuitively view the data displayed on the electrical control unit 712 while also protecting the electrical control unit 712.

[0053] refer to Figure 7 A storage box 72 is provided on the top of the upper housing 11. The storage box 72 is detachably connected to the upper housing 11 or may be integrally formed. Specifically, a disinfection device 722 is provided within the storage box 72, which can disinfect the items inside the storage box 72. In one embodiment, the storage box 72 is detachably connected to the upper housing 11, and a magnet 723 is provided on the cover 721 of the storage box 72. The magnet 723 is used to attract the upper housing 11 so that the cover 721 can completely fit the upper housing 11 to achieve a seal.

[0054] In one embodiment, the medical oxygen concentrator is equipped with handles 73, which span the upper housing 11 and connect to opposite sides of the upper housing 11. Because the oxygen concentrator in this design is relatively small, the provision of handles 73 enhances its portability, allowing the user to easily lift the concentrator and move it to the desired location, where it can continuously produce oxygen for the patient's breathing. It should be noted that the medical oxygen concentrator of the present invention has a compact structure, so its size and weight are reasonable for the user.

[0055] The medical oxygen concentrator is further provided with an air inlet cover 74, which is disposed on the upper housing 11 and covers the nozzle of the air inlet pipe 22. When the medical oxygen concentrator is not in operation, the air inlet cover 74 can be placed on the nozzle of the air inlet pipe 22 to prevent dust and interference. This prevents the nozzle from being blocked and thus affecting the normal operation of the medical oxygen concentrator before the oxygen concentrator is used again.

[0056] refer to Figure 8A shock-absorbing structure 75 is provided between the air pump 2 and the base 12. The shock-absorbing structure 75 comprises: an air pump 2, a base 12, a shock-absorbing spring 752, and a connecting bolt 754. The air pump 2 is provided with a first shock-absorbing member 751, which has a first mounting hole. A laterally extending mounting support is provided at the bottom of the air pump 2, which has a second mounting hole. The first shock-absorbing member 751 is mounted in the second mounting hole. The base 12 is provided with a second shock-absorbing member 753, which has a third mounting hole. A guide post 755 is provided on the inner surface of the bottom wall of the base 12. The guide post 755 extends in the height direction. The second shock-absorbing member 753 is sleeved on the guide post 755 through the third mounting hole. A connecting screw hole is provided at the top of the guide post 755. The shock-absorbing spring 752 is provided between the first shock-absorbing member 751 and the second shock-absorbing member 753. The connecting bolt 754 passes through the first mounting hole and is fastened to the connecting screw hole of the guide post 755. By installing a first shock absorber 751 on the mounting bracket of the air pump 2, a second shock absorber 753 mounted on the guide column 755 of the base 12, and a spring positioned between the first and second shock absorbers 751 and 753, the vibrations generated by the air pump 2 during operation are largely absorbed by the first and second shock absorbers 751, 753, and the shock-absorbing spring 752, minimizing the overall vibration of the medical oxygen concentrator. A connecting screw hole is provided at the top of the guide column 755, and a connecting bolt 754 passes through the first shock absorber 751 and the mounting bracket to elastically secure the air pump 2 to the base 12, preventing damage to the air pump 2 from external impacts during transportation.

[0057] During transportation, the medical oxygen concentrator is vibrated by external impact, and the vibration force will first be transmitted to the base 12, and then transmitted to the position of the air pump 2 through the second shock absorber 753, the shock absorber spring 752, the first shock absorber 751 in sequence through the base 12. However, the first abutting platform, the second abutting platform and the shock absorber spring 752 are all made of elastic materials, so the elastic abutment of the shock absorber spring 752 against the first abutting platform and the second abutting platform can further enhance the shock absorption effect of the shock absorption structure 75 composed of the first shock absorber 751, the second shock absorber 753 and the shock absorber spring 752.

[0058] During operation, the main sound emitted by the medical oxygen concentrator is the air pump 2. The air pump 2 produces certain noise and vibration during the process of compressing gas. Therefore, the shock-absorbing structure 75 composed of the first shock-absorbing member 751, the second shock-absorbing member 753 and the shock-absorbing spring 752 can reduce the impact of the working vibration of the air pump 2 on the medical oxygen concentrator and reduce the noise emitted by the vibration of the medical oxygen concentrator.

[0059] The air pump 2 is provided with at least four mounting brackets, and corresponding to the first shock absorbing member 751, the second shock absorbing member 753, the shock absorbing spring 752, and the connecting bolt 754. In this embodiment, there are four mounting brackets, and they are located at the four corners of the air pump 2, respectively. However, the present design is not limited to this. In other embodiments, the number of mounting brackets may be, but is not limited to, four, and may be three, six, eight, etc.

[0060] In one embodiment, a shock-absorbing washer 122 is further provided under the base. The provision of the shock-absorbing washer 122 can further reduce the noise generated by the vibration of the equipment and the external environment that may affect the normal operation of the medical oxygen concentrator.

[0061] The above descriptions are merely optional embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present description and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present invention.
