Description

Technical Field

[0001] This invention relates to the field of oxygen supply device technology, and more particularly to a medical oxygen supply device. Background Technology

[0002] When the hospital's oxygen demand is low, the excess oxygen produced by the oxygen generation system can be temporarily stored in the gas storage device for release during subsequent peak oxygen demand or when oxygen demand increases.

[0003] Existing oxygen storage devices mainly fall into two categories: multiple small storage devices (such as small oxygen cylinders) and a single large storage device (such as a large oxygen tank). Both of these methods have drawbacks: multiple small storage devices operate independently, preventing oxygen exchange and resulting in poor pressure stability during oxygen supply (oxygen is stored at a set pressure, and the pressure gradually decreases during output, with each storage device releasing a different amount of oxygen, leading to pressure variations); a leak in a single large storage device will directly cause the entire oxygen storage system to stop operating, and the large amount of oxygen leakage poses safety and resource waste risks. Summary of the Invention

[0004] To overcome the shortcomings mentioned in the background art, this invention provides a medical oxygen supply device, including an oxygen generator; an oxygen supply component is provided on one side of the oxygen generator, and the main oxygen outlet pipe of the oxygen generator is connected to the main oxygen inlet pipe of the oxygen supply component through a connecting pipe; a mounting frame is provided on one side of the oxygen generator, and an oxygen storage system is installed on the mounting frame; multiple oxygen storage components are provided in the oxygen storage system; each oxygen storage component includes a connecting pipe; a secondary oxygen outlet pipe of the oxygen generator is connected to a secondary oxygen inlet pipe of the oxygen supply component through the connecting pipe; multiple air storage bags are provided in the oxygen storage components; the air storage bags are connected to the connecting pipe, and oxygen is supplied to the air storage bags through the secondary oxygen outlet pipe of the oxygen generator; when the air storage bags are connected to the connecting pipe, the air storage bags in the oxygen storage components are interconnected; a compression plate is provided in the oxygen storage components; when the compression plate moves downward, it synchronously compresses the interconnected air storage bags in the oxygen storage components, and the air storage bags stably output oxygen to the oxygen supply component.

[0005] In a preferred embodiment of the present invention, the air storage bag is fixed on the transverse support plate of the mounting frame; a first electric push rod is installed on the longitudinal support plate of the mounting frame, and the telescopic part of the first electric push rod is fixedly connected to the extrusion plate; when the oxygen generator purifies the air storage bag with oxygen, the first electric push rod drives the extrusion plate to move upward; when the air storage bag delivers oxygen to the oxygen supply component, the first electric push rod drives the extrusion plate to move downward to extrude oxygen to the air storage bag.

[0006] In a preferred embodiment of the present invention, an electric switching valve is installed on each side of the connecting pipe.

[0007] In a preferred embodiment of the present invention, a pressure regulating valve is installed on the right side of the connecting pipe, and the pressure regulating valve is located to the left of the right electric switch valve.

[0008] In a preferred embodiment of the present invention, a pressure sensor is installed on the right side of the connecting pipe, and the pressure sensor is located to the left of the pressure regulating valve.

[0009] In a preferred embodiment of the present invention, a first self-sealing quick connector is installed on the connecting pipe; a second self-sealing quick connector is installed on the air reservoir; when the first self-sealing quick connector and the second self-sealing quick connector are connected, the air reservoir is connected to the connecting pipe; when the first self-sealing quick connector and the second self-sealing quick connector are separated, the first self-sealing quick connector and the second self-sealing quick connector each self-seal.

[0010] In a preferred embodiment of the present invention, a second electric push rod is installed on the transverse support plate of the mounting bracket, and the telescopic part of the second electric push rod is fixedly connected to the connecting pipe; by controlling the extension and retraction of the telescopic part of the second electric push rod, the connecting pipe is moved back and forth, so that the first self-sealing quick connector and the second self-sealing quick connector can be separated or connected.

[0011] In a preferred embodiment of the present invention, flexible tubing is provided on both sides of the connecting pipe.

[0012] In a preferred embodiment of the present invention, a plurality of extrusion strips are spliced ​​on the extrusion plate; it also includes a third electric push rod and a pressing connecting plate; the third electric push rod is installed on the extrusion plate, and the pressing connecting plate is fixedly connected to the telescopic part of the third electric push rod, and the pressing connecting plate is fixedly connected to the extrusion strips; the telescopic part of the third electric push rod pushes the pressing connecting plate to move downward with a constant extrusion force, thereby causing the extrusion strips to move downward and extruding the air storage bag below.

[0013] In a preferred embodiment of the present invention, the air reservoir is connected to the second self-sealing quick connector via a connecting hose; a magnetic support block is magnetically attached to the side of the air reservoir to support the connecting hose and keep it straight.

[0014] The beneficial effects are as follows: By setting multiple air storage bladders in each oxygen storage component and connecting the air storage bladders together with a connecting pipe, the air storage bladders can be interconnected and the air pressure can be kept consistent. When the extrusion plate is pressed down, it only needs to be pressed down at a constant rate to achieve stable oxygen output. Compared with the prior art that uses multiple non-interconnected small oxygen storage devices (such as small oxygen cylinders) to supply oxygen, the present invention can provide stable oxygen output pressure.

[0015] This invention connects multiple air storage bags to a connecting pipe. A pressure sensor can detect whether there is a leak in any state of the air storage bags. When a leak occurs, the connecting pipe and multiple air storage bags can be quickly and synchronously sealed by separating the first and second self-sealing quick connectors. At this time, only the leaking air storage bag will leak and release oxygen, resulting in minimal loss. This is superior to the storage method of the prior art that uses a single large air storage device.

[0016] Furthermore, after identifying a leak in the air reservoir, the present invention compresses the air reservoir with a constant pressure by having the compression bar continuously compress it. This causes the corresponding downward connecting plate to push the magnetic support block downward, causing the magnetic support block to detach from the air reservoir and no longer support the connecting hose. This prevents the second self-sealing quick connector from aligning with its matching first self-sealing quick connector, thus preventing the air reservoir from reconnecting to the connecting pipe and effectively kicking the leaking air reservoir out of the oxygen storage assembly.

Detailed Implementation

[0025] The invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are illustrated. However, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0026] Example 1: As Figures 1-7 As shown, a medical oxygen supply device includes an oxygen generator 1, an oxygen supply component 2, a mounting frame 3, and an oxygen storage system 4.

[0027] An oxygen supply assembly 2 is provided on one side of the oxygen generator 1. The main oxygen outlet pipe 1a of the oxygen generator 1 is connected to the main oxygen inlet pipe 2a of the oxygen supply assembly 2 through a connecting pipe. In this way, the oxygen generated by the oxygen generator 1 is supplied to the oxygen supply assembly 2. Then, the oxygen supply assembly 2 supplies oxygen to various medical devices in the hospital through multiple oxygen supply pipes 2c.

[0028] An oxygen generator 1 has a mounting bracket 3 on one side, and an oxygen storage system 4 is mounted on the mounting bracket 3. The oxygen storage system 4 has multiple oxygen storage components 41 distributed from top to bottom. Each oxygen storage component 41 includes a connecting pipe 404. The auxiliary oxygen outlet pipe 1b of the oxygen generator 1 is connected to the auxiliary oxygen inlet pipe 2b of the oxygen supply component 2 through the connecting pipe 404. Each oxygen storage component 41 has multiple air storage bags 401. The air storage bags 401 are connected to the connecting pipe 404, and oxygen is supplied to the air storage bags 401 through the auxiliary oxygen outlet pipe 1b of the oxygen generator 1. When the air storage bags 401 are connected to the connecting pipe 404, the air storage bags 401 in the oxygen storage component 41 are interconnected. Each oxygen storage component 41 has a compression plate 403. When the compression plate 403 moves downward, it synchronously compresses the interconnected air storage bags 401 in the oxygen storage component 41, and the air storage bags 401 stably output oxygen to the oxygen supply component 2.

[0029] The gas storage bag 401 is fixed on the transverse support plate 3a of the mounting frame 3; a first electric push rod 402 is installed on the longitudinal support plate 3b of the mounting frame 3, and the telescopic part of the first electric push rod 402 is fixedly connected to the extrusion plate 403; when the oxygen generator 1 purifies the gas storage bag 401 with oxygen, the first electric push rod 402 drives the extrusion plate 403 to move upward; when the gas storage bag 401 delivers oxygen to the oxygen supply component 2, the first electric push rod 402 drives the extrusion plate 403 to move downward to extrude oxygen to the gas storage bag 401.

[0030] An electric switching valve 4041 is installed on each side of the connecting pipe 404. A pressure regulating valve 4042 is installed on the right side of the connecting pipe 404, located to the left of the right-side electric switching valve 4041. A pressure sensor 4043 is installed on the right side of the connecting pipe 404, located to the left of the pressure regulating valve 4042.

[0031] A first self-sealing quick connector 4051 is installed on the connecting pipe 404; a second self-sealing quick connector 4052 is installed on the air reservoir 401; when the first self-sealing quick connector 4051 and the second self-sealing quick connector 4052 are connected, the air reservoir 401 is connected to the connecting pipe 404; when the first self-sealing quick connector 4051 and the second self-sealing quick connector 4052 are separated, the first self-sealing quick connector 4051 and the second self-sealing quick connector 4052 each self-seale.

[0032] like Figure 4 As shown, a second electric push rod 406 is installed on the transverse support plate 3a of the mounting bracket 3. The telescopic part of the second electric push rod 406 is fixedly connected to the connecting pipe 404. By controlling the extension and retraction of the telescopic part of the second electric push rod 406, the connecting pipe 404 is moved back and forth, allowing the first self-sealing quick connector 4051 and the second self-sealing quick connector 4052 to separate or connect.

[0033] Both sides of the connecting pipe 404 are provided with flexible hose sections 404a, and two electric switch valves 4041 are located between the two flexible hose sections 404a. When the connecting pipe 404 is driven to move back and forth, the flexible hose section 404a is twisted accordingly.

[0034] Multiple extrusion strips 403a are spliced ​​on the extrusion plate 403; it also includes a third electric push rod 407 and a downward pressing connecting plate 408; the third electric push rod 407 is installed on the extrusion plate 403, and the downward pressing connecting plate 408 is fixedly connected to the telescopic part of the third electric push rod 407, and the downward pressing connecting plate 408 is fixedly connected to the extrusion strips 403a; the telescopic part of the third electric push rod 407 pushes the downward pressing connecting plate 408 to move downward with a constant extrusion force, which drives the extrusion strips 403a to move downward and extrude the air storage bag 401 below; wherein, an extrusion strip 403a is provided on the upper side of each air storage bag 401.

[0035] The air reservoir 401 is connected to the second self-sealing quick connector 4052 via a connecting hose 401a; the side of the air reservoir 401 is magnetically attached to a magnetic support block 409, which supports the connecting hose 401a and keeps the connecting hose 401a straight.

[0036] When the hospital's oxygen demand is low, the excess oxygen produced by the oxygen generation system can be temporarily stored in the gas storage device for release during subsequent peak oxygen demand or when oxygen demand increases.

[0037] Existing oxygen storage devices mainly fall into two categories: multiple small storage devices (such as small oxygen cylinders) and a single large storage device (such as a large oxygen tank). Both of these methods have drawbacks: multiple small storage devices operate independently, preventing oxygen exchange and resulting in poor pressure stability during oxygen supply (oxygen is stored at a set pressure, and the pressure gradually decreases during output, with each storage device releasing a different amount of oxygen, leading to pressure variations); a leak in a single large storage device will directly cause the entire oxygen storage system to stop operating, and the large amount of oxygen leakage poses safety and resource waste risks.

[0038] like Figures 1-2 As shown, the present invention includes an oxygen generator 1, an oxygen supply component 2, and an oxygen storage system 4. The oxygen storage system 4 has multiple oxygen storage components 41 arranged from top to bottom (for ease of illustration, two oxygen storage components 41 are shown from top to bottom in the attached figure), and each oxygen storage component 41 includes multiple air storage bags 401 that can be interconnected (for ease of illustration, four air storage bags 401 are shown from left to right in the attached figure).

[0039] When this invention is in operation, the oxygen generated by the oxygen generator 1 is input into the oxygen supply assembly 2 through the main oxygen outlet pipe 1a, the connecting pipe (not shown in the figure), and the main oxygen inlet pipe 2a. The oxygen supply assembly 2 supplies oxygen to various medical devices in the hospital through multiple oxygen supply pipes 2c. When this invention is in operation, the first self-sealing quick connector 4051 and the second self-sealing quick connector 4052 are connected, and the air storage bags 401 in the same oxygen storage assembly 41 are interconnected, maintaining a consistent oxygen pressure.

[0040] Firstly, when the hospital's oxygen demand is low, the oxygen produced by the oxygen concentrator 1 can be input into the storage bag 401 through the auxiliary oxygen outlet pipe 1b and the connecting pipe 404, causing the storage bag 401 to inflate. At the same time, the compression plate 403 drives the first electric push rod 402 to move upward, and keeps the lower surface of the compression plate 403 in contact with the upper surface of the storage bag 401. In this way, the storage bag 401 can temporarily store the oxygen produced by the oxygen concentrator 1, and the air pressure of the multiple storage bags 401 remains consistent. When oxygen is input into the storage bag 401, the electric switch valve 4041 on the left opens and the electric switch valve 4041 on the right closes.

[0041] Secondly, when the hospital's oxygen demand increases, the oxygen in the storage bag 401 is released and delivered to the oxygen supply component 2; when the oxygen in the storage bag 401 is released, the electric switch valve 4041 on the left closes and the electric switch valve 4041 on the right opens; the specific release process is as follows:

[0042] The first electric push rod 402 is controlled to push the extrusion plate 403 downward. The extrusion plate 403 moves downward and simultaneously extrudes all the gas storage bladders 401 in the oxygen storage assembly 41. The oxygen released from the gas storage bladders 401 enters the oxygen supply assembly 2 through the connecting pipe 404. Since all the gas storage bladders 401 in the oxygen storage assembly 41 are interconnected, the oxygen pressure remains consistent, so that the oxygen injected into the oxygen supply assembly 2 by multiple gas storage bladders 401 at the same time can maintain a stable pressure (the oxygen pressure can be controlled by controlling the downward movement speed of the extrusion plate 403).

[0043] It should be noted that a pressure regulating valve 4042 is provided on the right side of the connecting pipe 404, and the pressure of oxygen injected into the oxygen supply component 2 is adjusted by the pressure regulating valve 4042.

[0044] In summary, this invention achieves interconnection between multiple air storage bladders 401 in each oxygen storage component 41, with the air storage bladders 401 all connected to a common connecting pipe 404, ensuring consistent air pressure. When the extrusion plate 403 presses downward, a stable oxygen output can be achieved simply by pressing downward at a constant rate. Compared to the prior art which uses multiple non-interconnected small oxygen storage devices (such as small oxygen cylinders) for oxygen supply, this invention can provide a stable oxygen output pressure.

[0045] Furthermore, the pressure sensor 4043 can detect whether there is a leak in the air reservoir 401. Specifically: First, when oxygen is introduced into the air reservoir 401, if there is a leak in the air reservoir 401, the pressure value of the pressure sensor 4043 will rise at a slower rate than expected; Second, when oxygen is released from the air reservoir 401, if there is a leak in the air reservoir 401, the downward movement speed of the compression plate 403 will not match the change in the pressure value of the pressure sensor 4043; Third, when the air reservoir 401 is storing oxygen at rest, if there is a leak in the air reservoir 401, the pressure value of the pressure sensor 4043 will decrease. Thus, the present invention can detect whether there is a leak in the air reservoir 401 in any state by using the pressure sensor 4043.

[0046] When it is known that a certain oxygen storage component 41 contains a gas storage bladder 401, the extension part of the second electric push rod 406 in the oxygen storage component 41 is pushed out, thereby driving the connecting pipe 404 forward, causing the first self-sealing quick connector 4051 and the second self-sealing quick connector 4052 to separate. When the first self-sealing quick connector 4051 and the second self-sealing quick connector 4052 separate, the first self-sealing quick connector 4051 and the second self-sealing quick connector 4052 each self-seale, thereby quickly and synchronously sealing the connecting pipe 404 and multiple gas storage bladders 401. At this time, only the leaking gas storage bladder 401 will leak and release oxygen, resulting in low loss; this is superior to the storage method of the existing technology that uses a single large gas storage device.

[0047] Furthermore, such as Figures 6-7 As shown, after the first self-sealing quick connector 4051 and the second self-sealing quick connector 4052 are separated, the third electric push rod 407 in this oxygen storage assembly 41 can be controlled to push the lower connecting plate 408 downward. The telescopic part of the third electric push rod 407 is pushed out with a constant extrusion force. The lower connecting plate 408 moves down, causing the extrusion strip 403a to move downward. Then, the extrusion strip 403a moves down and extrudes the air storage bladder 401 located below with a constant extrusion force. When the air storage bladder 401 leaks, the air storage bladder 401 will be continuously compressed, and the extrusion strip 403a will continue to descend. When the air storage bladder 401 does not leak, because the telescopic part of the third electric push rod 407 is only pushed out with a constant extrusion force, the air storage bladder 401 cannot be continuously compressed, and the extrusion strip 403a cannot continue to descend. In this way, the specific leaking air storage bladder 401 can be identified.

[0048] Furthermore, as the extrusion bar 403a continues to descend, the downward pressing connecting plate 408 connected to it will contact and press down on the magnetic support block 409, pushing the magnetic support block 409 away from the air reservoir 401. After the magnetic support block 409 is separated from the air reservoir 401, it no longer supports the connecting hose 401a, and the connecting hose 401a leaks out. Subsequently, the connecting hose 401a cannot support the weight of the second self-sealing quick connector 4052, and the second self-sealing quick connector 4052 hangs down under gravity, causing the connecting hose 401a to bend and deform. That is, the second self-sealing quick connector... The head 4052 is no longer aligned with its matching first self-sealing quick connector 4051; then, the telescopic part of the second electric push rod 406 is controlled to move the connecting pipe 404 backward, so that the first self-sealing quick connector 4051 and the second self-sealing quick connector 4052 are reconnected, allowing the air reservoir 401 to connect with the connecting pipe 404. The leaking air reservoir 401, because its second self-sealing quick connector 4052 is no longer aligned with its matching first self-sealing quick connector 4051, cannot connect with the connecting pipe 404 again and is kicked out of the oxygen storage assembly 41.

[0049] In summary, by connecting multiple air-storing bladders 401 to a connecting pipe 404, the pressure sensor 4043 can detect whether there is a leak in any state of the air-storing bladders 401. When a leak occurs, by separating the first self-sealing quick connector 4051 and the second self-sealing quick connector 4052, the connecting pipe 404 and the multiple air-storing bladders 401 can be quickly and synchronously sealed. At this time, only the leaking air-storing bladder 401 will leak and release oxygen, resulting in minimal loss. This is superior to the storage method of the prior art that uses a single large air-storing device.

[0050] Furthermore, after identifying a leak in the air reservoir 401, the present invention compresses the air reservoir 401 continuously by having the compression bar 403a compress it with a constant pressure. This compresses the air reservoir 401, allowing the corresponding downward connecting plate 408 to push the magnetic support block 409 downward. The magnetic support block 409 then detaches from the air reservoir 401 and no longer supports the connecting hose 401a. Consequently, the second self-sealing quick connector 4052 is no longer aligned with its matching first self-sealing quick connector 4051, preventing the air reservoir 401 from reconnecting to the connecting pipe 404. This effectively kicks the leaking air reservoir 401 out of the oxygen storage assembly 41.

[0051] The height of the lower connecting plate 408 is lower than that of the extrusion strip 403a.

[0052] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the invention without departing from the principles and spirit of the invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for illustrative purposes only and is not intended to limit the invention; rather, the scope of protection is defined by the content of the claims.
