Description

Technical Field

[0001] The present invention relates to the technical field of oxygen chambers, and in particular to a modular multifunctional oxygen chamber. Background Art

[0002] An oxygen chamber is a medical device used for hyperbaric oxygen therapy, which allows patients to inhale high-concentration oxygen in an environment above atmospheric pressure to promote body repair and relieve certain diseases. Currently, commonly used oxygen chambers are generally divided into single-person oxygen chambers and multi-person oxygen chambers. Single-person oxygen chambers directly introduce 100% pure oxygen into the chamber, allowing patients to breathe the oxygen in the chamber. Due to its technical limitations and high cost of use, it has been replaced by multi-person oxygen chambers.

[0003] The pressurized medium in the multi-person oxygen chamber is compressed air. The patient inhales pure oxygen through a mask or hood, and discharges the exhaled gas into the oxygen exhaust pipe of the oxygen chamber and out of the chamber through the oxygen exhaust valve. The oxygen concentration in the chamber environment must be controlled at ≤23% to prevent fire risks. In addition, when the patient takes off the mask or hood, the carbon dioxide in the exhaled gas will affect the gas composition in the oxygen chamber. In order to avoid the accumulation of carbon dioxide gas in the oxygen chamber and the excessive oxygen concentration, the oxygen chamber needs to be ventilated in time.

DETAILED DESCRIPTION

[0022] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present invention and are not configured to limit the present invention. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present invention by illustrating examples of the present invention.

[0023] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of the present invention. In the description of the present invention, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation, connection" should be understood in a broad sense, for example, it can be a fixed connection, or a detachable connection or an integral connection; it can be directly connected or indirectly connected. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0024] The embodiment of the present invention provides a modular multifunctional oxygen chamber. Figure 1 to Figure 5 The modular multifunctional oxygen chamber includes an oxygen chamber unit 101, a corridor 102 is fixedly installed in front of several oxygen chamber units 101, several oxygen chamber units 101 are evenly arranged along the length direction of the corridor 102, a sealed door is installed on the front side of the corridor 102, and the bottom of the corridor 102 is fixed to the base 103.

[0025] The tops of several oxygen chamber units 101 pass through the air inlet pipe 104 together, and the air inlet pipe 104 is respectively connected to the inside of several oxygen chamber units 101 for transporting gas into several oxygen chamber units 101. The bottoms of several oxygen chamber units 101 are connected to the exhaust pipe 105 through the exhaust mechanism 400. The exhaust pipe 105 is used to output the gas in the oxygen chamber unit 101 to the outside to avoid the accumulation of carbon dioxide in the oxygen chamber. The exhaust mechanism 400 is used to collect impurities such as dirt and flying debris in the oxygen chamber unit 101, so as to keep the environment in the oxygen chamber unit 101 clean and improve the user experience.

[0026] The air inlet pipe 104 is connected to the air compressor to dynamically adjust the pressure in the oxygen chamber to meet the oxygen therapy needs of different types of patients. The oxygen mask or hood in the oxygen chamber is connected to the oxygen source through a flow control valve. The precise control of the flow control valve can ensure that the oxygen concentration of the oxygen mask or hood is maintained within a stable and appropriate range, further improving the oxygen therapy effect of the patient.

[0027] A sliding door 106 is installed on one side of several oxygen cabin units 101 close to the corridor 102. The sliding door 106 is slidably configured in a guide groove 107. The guide groove 107 is fixed to the outer surface of the oxygen cabin unit 101. A limit block 108 is also fixed to the side of the oxygen cabin unit 101. The limit block 108 can overlap with the side of the sliding door 106, and the sliding door 106 can completely seal the oxygen cabin unit 101.

[0028] The above structure ensures that when the sliding door 106 seals the side of the oxygen chamber unit 101, the pressure in the oxygen chamber unit 101 can be adjusted by adjusting the pressure in the air inlet pipe 104 and the exhaust pipe 105, so that the oxygen chamber unit 101 can meet the use requirements of different patients for the oxygen chamber.

[0029] A mounting plate 109 is sealed and fixedly installed on the top of the oxygen chamber unit 101. The mounting plate 109 seals and separates the oxygen chamber unit 101 into two upper and lower chambers. A driving mechanism 200 is installed on the upper side of the mounting plate 109. The driving mechanism 200 connects the air inlet pipe 104 with the chamber on the lower side of the oxygen chamber unit 101. The driving mechanism 200 is used to evenly transport the high-pressure gas in the air inlet pipe 104 to various positions of the lower chamber of the oxygen chamber unit 101.

[0030] A plurality of nozzles 300 are fixedly mounted on the lower surface of the mounting plate 109 . The high-pressure gas in the air inlet pipe 104 is delivered to the nozzles 300 through the driving mechanism 200 . The nozzles 300 are used to evenly distribute the high-pressure gas inside the chamber at the lower side of the oxygen cabin unit 101 .

[0031] Through the cooperation of the driving mechanism 200 and the nozzle 300, the high-pressure gas in the air inlet pipe 104 is evenly distributed in the chamber on the lower side of the oxygen chamber unit 101. Through the convection of the gas, the oxygen concentration in the oxygen chamber is regulated, so that patients therein can receive oxygen therapy in an environment with appropriate oxygen concentration, thereby improving the use effect and user experience.

[0032] In addition, the airflow in the oxygen chamber unit 101 enters from the top and flows out from the bottom, and the carbon dioxide gas exhaled by the patient generally gathers at the bottom of the oxygen chamber due to its higher molecular mass. The flow of gas from top to bottom in the oxygen chamber is conducive to the discharge of carbon dioxide.

[0033] In addition, the downward flow of gas in the oxygen chamber effectively reduces the flying dust in the oxygen chamber unit 101, increases the purity and freshness of the gas inside the oxygen chamber unit 101, is conducive to keeping the environment in the oxygen chamber unit 101 clean, and improves the user experience.

[0034] The oxygen chamber unit 101 is internally provided with a pressure gauge for real-time monitoring of the internal pressure of the oxygen chamber unit 101 , and is internally provided with a concentration meter for real-time monitoring of the oxygen concentration, thereby facilitating the dynamic adjustment of the internal pressure and oxygen concentration of the oxygen chamber unit 101 .

[0035] As a further explanation of the above embodiments, see Figure 6 , Figure 7 , Figure 8The driving mechanism 200 includes a motor 201 fixedly mounted on a mounting plate 109, wherein the output end of the motor 201 is coaxially fixed with a first pulley 202, the first pulley 202 is driven by a transmission belt 203 and a second pulley 204, and the second pulley 204 is rotatably mounted on the upper surface of the mounting plate 109. This structure enables the motor 201 to drive the first pulley 202 to rotate through its output end, and through the belt transmission connection relationship among the first pulley 202, the transmission belt 203 and the second pulley 204, the first pulley 202 can drive the second pulley 204 to rotate synchronously in the forward and reverse directions through the transmission belt 203.

[0036] The side of the transmission belt 203 is fixedly connected to the slider 205, and the slider 205 is slidably configured on the guide rail 206. The guide rail 206 is fixedly connected to the upper surface of the mounting plate 109. Therefore, by driving the first pulley 202 to rotate forward and reversely through the motor 201, the transmission belt 203 can drive the slider 205 to slide back and forth along the length direction of the guide rail 206.

[0037] A switching valve 210 is fixedly installed on the side of the slider 205 away from the motor 201. The top of the switching valve 210 is fixedly connected to the intake pipe 104 through a hose. The bottom end of the switching valve 210 overlaps the upper surface of the guide rod 207 and can slide back and forth along the length direction of the guide rod 207. The guide rod 207 is arranged parallel to the guide rail 206. The guide rod 207 is fixedly connected to the upper surface of the mounting plate 109. The guide rod 207 is provided with a plurality of pits 208 along the length direction. The bottom end of the switching valve 210 can be clamped in the pit 208, and the bottom of the pit 208 is connected to the nozzle 300 through a through hole 209 penetrating the mounting plate 109.

[0038] The upper surface of the guide rod 207 is provided with a long groove recessed downward along its length direction, so that the bottom end of the switching valve 210 will not be separated from the upper surface of the guide rod 207 when overlapping.

[0039] When the switching valve 210 overlaps the upper surface of the guide rod 207, the switching valve 210 is in an open circuit state, that is, the air intake pipe 104 cannot be connected to the nozzle 300 through the switching valve 210. When the bottom end of the switching valve 210 is stuck in the pit 208, the switching valve 210 is in a passage state. At this time, the air intake pipe 104 can be connected to the nozzle 300 through the switching valve 210. Therefore, through the change of the position of the switching valve 210 and the on-off state of the switching valve 210, the high-pressure gas in the air intake pipe 104 can be transported to each nozzle 300 installed on the lower surface of the mounting plate 109, thereby effectively dispersing the gas evenly inside the oxygen cabin unit 101.

[0040] As a further explanation of the above embodiments, see Figure 7 , Figure 8The switching valve 210 includes an air chamber 211, the top of the air chamber 211 is fixedly connected to the intake pipe 104 through a hose, the bottom of the air chamber 211 is sealed and slidably sleeved inside the air nozzle 212, the air nozzle 212 is fixedly connected to the first end of the first spring 213, the first spring 213 is sleeved on the outside of the air chamber 211, and the second end of the first spring 213 is fixedly connected to the air chamber 211.

[0041] A plug 214 is fixedly installed inside the bottom end of the air chamber 211, and the plug 214 can block the channel coaxially opened inside the air nozzle 212. The bottom end of the air nozzle 212 can overlap with the upper surface of the guide rod 207, and the bottom end of the air nozzle 212 can also be sealed and clamped inside the pit 208.

[0042] When the bottom end of the air nozzle 212 overlaps with the upper surface of the guide rod 207, the first spring 213 is compressed and the plug 214 is arranged in the channel opened inside the air nozzle 212, thereby completely blocking the channel of the air nozzle 212, resulting in the high-pressure gas in the intake pipe 104 being unable to be discharged to the outside after being transported to the inside of the air chamber 211 through the hose, that is, the switching valve 210 is in an open circuit state at this time.

[0043] When the bottom seal of the air nozzle 212 is clamped in the pit 208, the plug 214 no longer blocks the passage of the air nozzle 212. At this time, the high-pressure gas in the intake pipe 104 is transported to the inside of the air chamber 211 through the hose, and is transported to the nozzle 300 through the air nozzle 212 and the through hole 209.

[0044] Therefore, through the above structure, when the position of the switching valve 210 changes along the length direction of the guide rod 207, the switching valve 210 can be intermittently turned on and off, thereby transporting the high-pressure gas in the air intake pipe 104 to the positions of different nozzles 300 at the top of the oxygen chamber unit 101, thereby achieving uniform distribution of the gas in the oxygen chamber unit 101.

[0045] As a further explanation of the above embodiments, see Figure 7 , Figure 8 The nozzle 300 includes a pipe 301, the top of the pipe 301 is fixedly connected to the through hole 209, the interior of the pipe 301 gradually narrows from bottom to top, and a sealing ball 302 is arranged inside the pipe 301 to move along it. The sealing ball 302 can be sealed and overlapped with the top of the inner surface of the pipe 301, and the sealing ball 302 is fixedly connected to the first end of the second spring 303, and the second end of the second spring 303 is fixedly connected to the pipe 301.

[0046] An annular sleeve 304 is rotatably mounted at the bottom of the pipe 301 , and spiral blades 305 are coaxially mounted inside the annular sleeve 304 .

[0047] The purpose of the above structure is that when the high-pressure gas in the air inlet pipe 104 enters the oxygen chamber unit 101 through the nozzle 300, it can only flow unidirectionally from top to bottom along the pipe 301, and the gas in the oxygen chamber unit 101 cannot flow out through the pipe 301, thereby effectively controlling the pressure in the oxygen chamber unit 101.

[0048] In addition, the high-pressure gas entering the interior of the pipe 301 is output to the interior of the oxygen chamber unit 101 by rotating the annular sleeve 304 and the spiral blades 305 installed at the bottom of the pipe 301. At this time, due to the interaction between the flow of gas and the spiral blades 305, the annular sleeve 304 and the spiral blades 305 are further driven to rotate along the axis of the pipe 301, so that the direction of the airflow ejected from the bottom end of the annular sleeve 304 changes all the time. This method further enhances the uniform distribution of the high-pressure gas in the oxygen chamber unit 101.

[0049] When the high-pressure gas in the air intake pipe 104 enters the pipe 301 through the through hole 209, the sealing ball 302 is pushed downward to compress the second spring 303, so that the gas can enter the pipe 301 through the gap between the sealing ball 302 and the inner wall of the pipe 301. When the high-pressure gas no longer enters the pipe 301 through the through hole 209, the sealing ball 302 moves upward under the elastic force of the second spring 303 and overlaps with the top of the inner surface of the pipe 301 in a sealed manner, so that the gas inside the oxygen cabin unit 101 cannot be discharged outward through the pipe 301.

[0050] As a further explanation of the above embodiments, see Fig. 9 , Fig.10 The exhaust mechanism 400 includes a filter box 401 fixedly connected to the bottom of the oxygen cabin unit 101, a first filter plate 402 is fixedly installed on the top of the filter box 401, and is used to separate the filter box 401 and the inner cavity of the oxygen cabin unit 101, and a plurality of first filter holes 403 are evenly opened on the first filter plate 402, and the first filter holes 403 connect the oxygen cabin unit 101 and the filter box 401, and the side of the filter box 401 is fixedly connected to the first end of the air duct 406, and the second end of the air duct 406 is fixedly connected to the inlet of the air flow regulator 407, and the outlet of the air flow regulator 407 is fixedly connected to the exhaust pipe 105.

[0051] The filter box 401 has a detachable sealed installation configuration inside thereof with an installation box 404 , in which filter material can be installed. A plurality of second filter holes 405 are evenly opened on the side wall of the installation box 404 close to the air duct 406 .

[0052] The above structure allows the gas in the oxygen chamber unit 101 to first enter the filter box 401 through the first filter holes 403 on the first filter plate 402, further pass through the filter material inside the mounting box 404 and be transported to the air duct 406 through the second filter holes 405, and finally be discharged into the exhaust pipe 105 through the air flow regulator 407.

[0053] Through the gas flow in the above manner, when the gas in the oxygen chamber unit 101 is discharged to the outside, impurities such as flying debris and dirt in the oxygen chamber unit 101 can be brought into the installation box 404 for filtration and collection, thereby keeping the environment in the oxygen chamber unit 101 clean.

[0054] In addition, by adjusting the flow rate of the gas discharged from the oxygen chamber unit 101 through the airflow regulator 407, the internal pressure of the oxygen chamber unit 101 can be adjusted to meet the patient's needs for different pressures.

[0055] According to the embodiments of the present invention as described above, these embodiments do not describe all the details in detail, nor do they limit the invention to the only specific embodiments. Obviously, based on the above description, many modifications and changes can be made. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can make good use of the present invention and the modified use based on the present invention.
