Description

Technical Field

[0001] The present invention relates to the technical field of oxygen chambers, and particularly to a modular multi-functional oxygen chamber. Background Art

[0002] An oxygen chamber is a medical device used for hyperbaric oxygen therapy. By allowing patients to inhale high-concentration oxygen in an environment above atmospheric pressure, it promotes body repair and alleviates certain diseases. Currently, commonly used oxygen chambers are generally divided into single-person oxygen chambers and multi-person oxygen chambers. The single-person oxygen chamber directly introduces 100% pure oxygen into the chamber for the patient to breathe. Due to its technical limitations and high usage costs, it has been replaced by multi-person oxygen chambers.

[0003] The pressurizing medium inside the multi-person oxygen chamber is compressed air. Patients inhale pure oxygen through a mask or a hood and exhale the gas into the oxygen discharge pipe of the oxygen chamber, which is then discharged outside the chamber through an oxygen discharge valve. The oxygen concentration in the chamber environment needs to be controlled at ≤23% to prevent the risk of fire. Additionally, when the patient removes the mask or the hood, the carbon dioxide in the exhaled gas will affect the gas composition inside the oxygen chamber. To avoid the accumulation of carbon dioxide gas and the over-standard oxygen concentration inside the oxygen chamber, it is necessary to timely ventilate the oxygen chamber.

[0004] Currently, the commonly used oxygen chambers in medical institutions generally use fixed outlets and inlets for gas exchange, and cannot reasonably adjust the gas concentration inside the oxygen chamber adaptively in terms of space, thus affecting the patient's usage experience.

[0046] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. To make the objectives, 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 some of these specific details. The following description of the embodiments is only to provide a better understanding of the present invention by showing examples of the present invention.

[0047] The orientation terms appearing in the following description are all the 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, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] An embodiment of the present invention provides a modular multi-functional oxygen chamber. Refer to Figures 1 to 5 , the modular multi-functional oxygen chamber includes an oxygen chamber unit 101. A corridor 102 is fixedly installed directly in front of a plurality of oxygen chamber units 101. The plurality of oxygen chamber units 101 are evenly arranged along the length direction of the corridor 102. A sealing door is installed on the front side of the corridor 102. The bottom of the corridor 102 is fixed to a base 103.

[0049] The tops of a plurality of oxygen chamber units 101 jointly pass through an intake pipe 104. The intake pipe 104 is respectively communicated with the interiors of the plurality of oxygen chamber units 101 for delivering gas into the plurality of oxygen chamber units 101. The bottoms of the plurality of oxygen chamber units 101 are all communicated with an exhaust pipe 105 through an exhaust mechanism 400. The exhaust pipe 105 is used to output the gas in the oxygen chamber unit 101 to avoid the accumulation of carbon dioxide in the oxygen chamber. The exhaust mechanism 400 is used for collecting impurities such as dirt and flying debris in the oxygen chamber unit 101, thereby keeping the environment in the oxygen chamber unit 101 clean and improving the user experience.

[0050] Among them, the intake pipe 104 is communicated with an air compressor for dynamically adjusting the pressure in the oxygen chamber, so as to meet the oxygen therapy needs of different types of patients. The oxygen mask or hood in the oxygen chamber is communicated with an oxygen source through a flow regulating valve. Through the precise control of the flow regulating valve, it can be ensured that the oxygen concentration of the oxygen mask or hood remains within a stable and appropriate range, further improving the oxygen therapy effect of the patient.

[0051] Sliding doors 106 are installed on one side of several oxygen chamber units 101 close to the corridor 102. The sliding doors 106 are slidably arranged in the guide grooves 107, and the guide grooves 107 are fixed to the outer surface of the oxygen chamber units 101. A limiting block 108 is also fixed to the side surface of the oxygen chamber unit 101. The limiting block 108 can overlap with the side surface of the sliding door 106, and the sliding door 106 can completely seal the oxygen chamber unit 101.

[0052] When the sliding door 106 seals the side surface of the oxygen chamber unit 101, the pressure inside the oxygen chamber unit 101 can be adjusted by adjusting the pressure in the intake pipe 104 and the exhaust pipe 105, so that the oxygen chamber unit 101 can meet the usage requirements of different patients for the oxygen chamber.

[0053] A mounting plate 109 is fixedly installed on the top of the oxygen chamber unit 101 in a sealed manner. The mounting plate 109 divides the oxygen chamber unit 101 into upper and lower chambers in a sealed manner. A driving mechanism 200 is installed on the upper side of the mounting plate 109. The driving mechanism 200 connects the intake pipe 104 with the lower chamber of the oxygen chamber unit 101, and the driving mechanism 200 is used to evenly transport the high-pressure gas in the intake pipe 104 to various positions in the lower chamber of the oxygen chamber unit 101.

[0054] A plurality of nozzles 300 are fixedly installed on the lower surface of the mounting plate 109. The high-pressure gas in the intake pipe 104 is transported to the nozzles 300 through the driving mechanism 200, and the nozzles 300 are used to evenly disperse the high-pressure gas inside the lower chamber of the oxygen chamber unit 101.

[0055] Through the cooperation of the driving mechanism 200 and the nozzles 300, the high-pressure gas in the intake pipe 104 is evenly dispersed in the lower chamber of the oxygen chamber unit 101. Through the convection of the gas, the oxygen concentration in the oxygen chamber is adjusted, so that the patients inside can receive oxygen therapy in an environment with appropriate oxygen concentration, improving the usage effect and user experience.

[0056] In addition, the air flow in the oxygen chamber unit 101 enters from above and exits from below. Since the carbon dioxide gas exhaled by the patients has a relatively high molecular mass, it generally accumulates at the bottom of the oxygen chamber. The upward-downward air flow mode in the oxygen chamber is conducive to the discharge of carbon dioxide.

[0057] Moreover, the upward-downward air flow mode in the oxygen chamber effectively reduces the dust in the oxygen chamber unit 101, increases the purity and freshness of the gas inside the oxygen chamber unit 101, is conducive to maintaining the environmental cleanliness inside the oxygen chamber unit 101, and improves the user experience.

[0058] Among them, a pressure gauge for real-time monitoring of the internal pressure of the oxygen chamber unit 101 is configured inside the oxygen chamber unit 101. At the same time, a concentration meter for real-time monitoring of the oxygen concentration is also configured inside the oxygen chamber unit 101, so as to facilitate the dynamic adjustment of the internal pressure and oxygen concentration of the oxygen chamber unit 101.

[0059] As a further explanation of the above embodiment, refer to Figure 6 、 Figure 7 、 Figure 8 ., the driving mechanism 200 includes a motor 201 fixedly installed on the mounting plate 109. The output end of the motor 201 is coaxially fixed with the first pulley 202. The first pulley 202 is belt-driven with the second pulley 204 through a transmission belt 203. The second pulley 204 is rotatably installed 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. Through the belt drive connection relationship of 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 forward and backward through the transmission belt 203.

[0060] The side surface of the transmission belt 203 is fixedly connected to the slider 205. 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 backward by the motor 201, the transmission belt 203 can drive the slider 205 to reciprocate along the length direction of the guide rail 206.

[0061] A switching valve 210 is fixedly installed on the side of the slider 205 away from the motor 201. The top end of the switching valve 210 is fixedly communicated with the air inlet pipe 104 through a hose. The bottom end of the switching valve 210 is lapped on the upper surface of the guide rod 207 and can reciprocate 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. A plurality of pits 208 are formed along the length direction of the guide rod 207. The bottom end of the switching valve 210 can be clamped in the pits 208. The bottom of the pits 208 is communicated with the nozzle 300 through a through hole 209 penetrating the mounting plate 109.

[0062] Among them, a long groove recessed downward is formed along the length direction of the upper surface of the guide rod 207, so that the bottom end of the switching valve 210 will not be separated when it is lapped on the upper surface of the guide rod 207.

[0063] When the switching valve 210 overlaps with the upper surface of the guide rod 207, the switching valve 210 is in an open circuit state, that is, the intake pipe 104 cannot communicate with the nozzle 300 through the switching valve 210. When the bottom end of the switching valve 210 is clamped in the pit 208, the switching valve 210 is in a conducting state. At this time, the intake pipe 104 can communicate with the nozzle 300 through the switching valve 210. Therefore, through the change in the position of the switching valve 210 and combined with the on-off state of the switching valve 210, the high-pressure gas in the intake pipe 104 can be delivered 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.

[0064] As a further explanation of the above embodiment, refer to Figure 7 、 Figure 8 The switching valve 210 includes an air chamber 211. The top of the air chamber 211 is fixedly communicated with the intake pipe 104 through a hose. The bottom of the air chamber 211 is hermetically 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 outside the air chamber 211, and the second end of the first spring 213 is fixedly connected to the air chamber 211.

[0065] A plug 214 is fixedly installed inside the bottom end of the air chamber 211. 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 hermetically clamped inside the pit 208.

[0066] When the bottom end of the air nozzle 212 overlaps with the upper surface of the guide rod 207, at this time, the first spring 213 is compressed, and the plug 214 is disposed in the channel opened inside the air nozzle 212, thereby completely blocking the channel of the air nozzle 212. As a result, after the high-pressure gas in the intake pipe 104 is delivered to the inside of the air chamber 211 through the hose, it cannot be discharged outward, that is, at this time, the switching valve 210 is in an open circuit state.

[0067] When the bottom of the air nozzle 212 is hermetically clamped in the pit 208, the plug 214 no longer blocks the channel of the air nozzle 212. At this time, the high-pressure gas in the intake pipe 104 is delivered to the inside of the air chamber 211 through the hose and is delivered to the nozzle 300 through the air nozzle 212 and the through hole 209.

[0068] Therefore, through the above structure, when realizing the change in the position of the switching valve 210 along the length direction of the guide rod 207, the on-off of the switching valve 210 can be intermittently realized, so as to deliver the high-pressure gas in the intake pipe 104 to the positions where different nozzles 300 are located at the top of the oxygen cabin unit 101, realizing the uniform dispersion of the gas inside the oxygen cabin unit 101.

[0069] As a further explanation of the above embodiment, refer toFigure 7 , Figure 8 , the nozzle 300 includes a pipe 301. The top of the pipe 301 is fixedly communicated with the through hole 209. The inside of the pipe 301 gradually narrows from bottom to top. A sealing ball 302 is arranged inside the pipe 301 and moves along it. The sealing ball 302 can be hermetically lapped with the top of the inner surface of the pipe 301. The sealing ball 302 is fixedly connected to the first end of a second spring 303, and the second end of the second spring 303 is fixedly connected to the pipe 301.

[0070] A ring sleeve 304 is rotatably installed at the bottom of the pipe 301, and a spiral fan blade 305 is coaxially installed inside the ring sleeve 304.

[0071] 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, so as to effectively control the pressure in the oxygen chamber unit 101.

[0072] In addition, the high-pressure gas entering the inside of the pipe 301 is output to the inside of the oxygen chamber unit 101 through the ring sleeve 304 and the spiral fan blade 305 rotatably installed at the bottom of the pipe 301. At this time, due to the interaction between the gas flow and the spiral fan blade 305, it will further drive the ring sleeve 304 and the spiral fan blade 305 to rotate along the axis of the pipe 301, so that the orientation of the air flow ejected from the bottom end of the ring sleeve 304 changes at all times. This method further enhances the uniform dispersion of the high-pressure gas in the oxygen chamber unit 101.

[0073] When the high-pressure gas in the air inlet pipe 104 enters the pipe 301 through the through hole 209, it pushes the sealing ball 302 downward to compress the second spring 303, so that the gas can enter the inside of 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 is hermetically lapped with the top of the inner surface of the pipe 301, so that the gas inside the oxygen chamber unit 101 cannot flow out through the pipe 301.

[0074] As a further explanation of the above embodiment, see Figure 9 , Figure 10, the exhaust mechanism 400 includes a filter box 401 fixedly communicated with the bottom of the oxygen chamber unit 101. A first filter plate 402 is fixedly installed on the top of the filter box 401 for separating the inner cavities of the filter box 401 and the oxygen chamber unit 101. A number of first filter holes 403 are evenly formed in the first filter plate 402, and the first filter holes 403 communicate the oxygen chamber unit 101 and the filter box 401. The side surface of the filter box 401 is fixedly communicated with the first end of an air duct 406, the second end of the air duct 406 is fixedly communicated with the inlet of an air flow regulator 407, and the outlet of the air flow regulator 407 is fixedly communicated with an exhaust pipe 105.

[0075] A mounting box 404 is detachably and sealingly installed inside the filter box 401. Filter materials can be installed in the mounting box 404, and a number of second filter holes 405 are evenly formed in the side wall of the mounting box 404 close to the air duct 406.

[0076] The above structure enables the gas in the oxygen chamber unit 101 to first enter the filter box 401 through a number of first filter holes 403 in the first filter plate 402, further pass through the filter materials inside the mounting box 404 and be conveyed into 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.

[0077] Through the gas flow in the above manner, during the process of discharging the gas in the oxygen chamber unit 101 to the outside, chips, dirt and other impurities in the oxygen chamber unit 101 can be brought into the mounting box 404 for filtering and collection, so as to keep the environment in the oxygen chamber unit 101 clean.

[0078] In addition, by adjusting the flow rate of the gas discharged from the oxygen chamber unit 101 through the air flow regulator 407, the internal pressure of the oxygen chamber unit 101 can be adjusted, so as to meet the requirements of patients for different pressures.

[0079] 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 only the specific embodiments. Obviously, according to the above description, many modifications and variations can be made.
