Description

Technical Field

[0001] This disclosure relates to the field of medical device technology, and more specifically, to a pressure regulating component. Background Technology

[0002] In the medical field, it is common to supply patients with medical gases (such as oxygen). This requires a pressure regulating assembly connected to a gas source, which regulates the pressure of the gas supplied to the patient. However, in existing pressure regulating assemblies, when the intake component malfunctions, there is usually no spare component to take over the gas supply in time. Even if a spare component can be used to resume gas supply, the patient will still not receive a sufficient gas supply during the disassembly and reinstallation process (vacuum period). This undoubtedly has an adverse effect on the patient's health and may even endanger their life.

[0003] Therefore, a new type of pressure regulating component is needed, which can switch to a backup intake component in a timely manner when the intake component used for intake malfunctions, to ensure a sufficient and continuous supply of gas. Utility Model Content

[0004] This disclosure provides a pressure regulating assembly that overcomes the aforementioned problems of the prior art and further allows for disassembly and maintenance, extending the service life of the pressure regulating assembly.

[0006] The pressure regulating component disclosed herein has the following advantages compared to the prior art:

[0007] (1) In the event that the main intake component fails and cannot continue to supply gas, it can switch to the backup intake component in a timely manner to ensure a continuous supply of gas and improve the reliability of the pressure regulating component.

[0018] To keep the following description of the embodiments of this application clear and concise, detailed descriptions of known functions and known components are omitted.

[0019] like Figure 1 As shown, the pressure regulating assembly 100 provided in this disclosure includes a pressure regulating member 200 and a base 300. The pressure regulating member 200 is used to connect to a gas source (not shown in the figure), such as a high-pressure gas cylinder in a hospital or an industrial gas cylinder, and to regulate the pressure of the output gas. The pressure regulating member 200 can be connected to a fastener 400. Figure 3 (As shown in the figure) It is fixedly mounted on the base 300, which can also be fixed to the wall or furniture by additional fasteners.

[0020] Alternatively, the pressure regulating assembly 100 may consist only of the pressure regulating member 200, which is fixed to a wall or furniture by fasteners 400. This improves the applicability of the pressure regulating assembly 100.

[0021] The following will combine Figures 1-4 The pressure regulating component 200 of the pressure regulating assembly 100 is described in detail.

[0022] like Figure 1 As shown, the pressure regulating component 200 includes a main intake component 210, an outlet component 220, and a sub-regulating component 230 fluidly disposed between the two. Under normal operating conditions, the main intake component 210 is connected to a gas source containing gas at a certain pressure. Gas from the gas source can sequentially pass through the main intake component 210, the sub-regulating component 230, and then be output through the outlet component 220.

[0023] Specifically, the sub-regulating assembly 230 may include a first switching valve 231, a regulating valve 232, a safety valve 233, and a second switching valve 234 connected in sequence. The first switching valve 231 is connected to the main air intake component 210, and the second switching valve 234 is connected to the air outlet component 220. The first switching valve 231 and the second switching valve 234 are used to control the flow and shut-off of gas, and are preferably ball valves. The regulating valve 232 regulates the pressure of the gas flowing through it from a higher than desired predetermined pressure to a predetermined pressure for use by, for example, patients. If the regulating valve 232 malfunctions or fails, and the gas passing through the regulating valve 232 does not drop to the expected low pressure, the safety valve 233 can be used to release the gas, preventing high-pressure gas from being discharged from the air outlet component 220.

[0024] In an embodiment, to prevent the inability to supply air continuously and efficiently in the event of a failure of the main intake component 210, the sub-regulation component 230 of this disclosure may further include a first backup intake component 235 and a second backup intake component 236. The first backup intake component 235 is disposed between the main intake component 210 and the regulating valve 232, specifically between the first switching valve 231 and the regulating valve 232. The second backup intake component 236 is disposed between the regulating valve 232 and the air outlet component 220, specifically between the safety valve 233 and the second switching valve 234.

[0025] When the main intake component 210 is working normally, both the first backup intake component 235 and the second backup intake component 236 can be used as gas flow components; when the main intake component 210 fails and cannot continue to supply gas, both the first backup intake component 235 and the second backup intake component 236 can be alternatively connected to the gas source, and depending on the current pressure value of the gas in the gas source, the gas source can be selected to be connected to one of the first backup intake component 235 and the second backup intake component 236. For example, when the current pressure of the gas in the gas source is higher than the predetermined pressure, the gas source can be connected to the first backup air intake component 235. The gas from the gas source is regulated to the predetermined pressure through the regulating valve 232 via the first backup air intake component 235, and then flows through the safety valve 233, the second backup air intake component 236, the second switching valve 234, and finally discharged through the air outlet component 220. When the current pressure of the gas in the gas source is less than or equal to the predetermined pressure, the gas source can be connected to the second backup air intake component 236. The gas from the gas source flows directly through the second switching valve 234 and the air outlet component 220 via the second backup air intake component 236 and is discharged.

[0026] In this way, if the main intake component 210 fails and cannot continue to supply gas, the gas source can be alternatively switched to one of the first backup intake component 235 and the second backup intake component 236 according to the current gas pressure in the gas source, thus ensuring a continuous gas supply and improving the reliability of the pressure regulating component 200.

[0027] To further improve the reliability of the pressure regulating assembly 100, the pressure regulating member 200 may include two sub-regulating assemblies 230, which are arranged side by side between the main intake member 210 and the outlet member 220. In operation, only one of the sub-regulating assemblies 230 is in the air supply state.

[0028] Optionally, the central axis of the main intake component 210 and the central axis of the exhaust component 220 are horizontally aligned, and the two sub-adjustment components 230 are axially symmetrical about the central axes of the main intake component 210 and the exhaust component 220. The pressure regulating component 200 is generally rectangular in structure. Furthermore, the first backup intake component 235 and the second backup intake component 236 extend from the right angles of the rectangle; the main intake component 210 and the exhaust component 220 are located on opposite sides of the rectangle and extend in opposite directions. In one embodiment, such as Figure 1 As shown, the main intake component 210 and two first switching valves 231 are located on one side of the rectangle; the exhaust component 220 and two second switching valves 234 are located on the other side opposite the main intake component 210 of the rectangle; the other two opposite sides of the rectangle are respectively provided with a set of regulating valves 232 and safety valves 233 of a sub-regulating assembly 230, and a set of regulating valves and safety valves of another sub-regulating assembly.

[0029] In one embodiment, the first backup air intake component 235 may include a first air intake tee 235A, one end of the horizontal main pipe of the first air intake tee 235A is connected to a regulating valve 232, the other end is used to connect to an air source, and its vertical branch pipe is connected to a first switching valve 231.

[0030] In one embodiment, a first connecting tee 237 is provided between the regulating valve 232 and the second backup air intake component 236. The two ends of the horizontal main pipe of the first connecting tee 237 are respectively connected to the regulating valve 232 and the second backup air intake component 236, and the vertical branch pipe of the first connecting tee 237 is connected to the safety valve 233. Further, the second backup air intake component 236 may include a second air intake tee 236A. One end of the horizontal main pipe of the second air intake tee 236A is connected to the regulating valve 232 via the horizontal main pipe of the first connecting tee 237, and the other end is used to connect to an air source. The vertical branch pipe of the second air intake tee 236A is connected to the second switching valve 234. In one embodiment, the main air intake component 210 can be connected to the sub-regulating assembly 230 via the second connecting tee 238, or it can be connected to two sub-regulating assemblies 230 via the second connecting tee 238. That is, the two ends of the horizontal main pipe of the second connecting tee 238 are respectively connected to two sub-regulating assemblies 230, and the vertical branch pipe of the second connecting tee 238 is connected to the main air intake component 210. Correspondingly, the main intake component 210 may include a fourth connecting tee 210A and a first sensor 210B. One end of the horizontal main pipe of the fourth connecting tee 210A is connected to the vertical branch pipe of the second connecting tee 238, and the other end is used to connect to the air source. The first sensor 210B is fixedly connected to the vertical branch pipe of the fourth connecting tee 210A to detect the gas pressure at the intake port.

[0031] In one embodiment, the air outlet component 220 can be connected to the sub-regulating assembly 230 via the third connecting tee 239, or it can be connected to two sub-regulating assemblies 230 via the third connecting tee 239. That is, the two ends of the horizontal main pipe of the third connecting tee 239 are respectively connected to the two sub-regulating assemblies 230, and the vertical branch pipe of the third connecting tee 239 is connected to the air outlet component 220. Correspondingly, the air outlet component 220 may include a fifth connecting tee 220A and a second sensor 220B. One end of the horizontal main pipe of the fifth connecting tee 220A is connected to the vertical branch pipe of the third connecting tee 239, and the other end is used to connect to the air source. The second sensor 220B is fixedly connected to the vertical branch pipe of the fifth connecting tee 220A to detect the gas pressure at the air outlet.

[0032] In a preferred embodiment, the end of the horizontal main pipe of the first intake tee 235A and the second intake tee 236A used for connecting to the air source (i.e. Figure 2 and Figure 3 The outer sides shown are all connected to non-interchangeable threaded connectors (NISTs). Each NIST has a check valve inside, allowing pressurized gas from the gas source to enter the pressure regulating component through the NIST, while preventing gas from the pressure regulating component from escaping through the NIST.

[0033] In a preferred embodiment, adjacent components among the second connecting tee 238, the first switching valve 231, the first intake tee 235A, the regulating valve 232, and the first connecting tee 237 are detachably connected by nuts, and adjacent components among the second intake tee 236A, the second switching valve 234, and the third connecting tee 239 are detachably connected by nuts. This method facilitates after-sales service and installation of the components, and allows for timely and efficient replacement in case of component failure.

[0034] In addition, as shown in the figure, the sub-regulating assembly 230 may also include a pressure gauge 240, which is connected to the regulating valve 232 for detecting the pressure of the gas flowing through the regulating valve 232.

[0035] As described above, the pressure regulating component 200 may include two sub-regulating components 230 arranged side-by-side between the main intake component 210 and the outlet component 220. Normally, only one of the two sub-regulating components 230 is in use; that is, the first switching valve 231 and the second switching valve 234 of one sub-regulating component 230 are open, while the first switching valve 231 and the second switching valve 234 of the other sub-regulating component 230 are closed, forming a single gas passage. When the gas source is connected to different intake ports, different single intake passages will be formed. For example, when the gas source is connected to the intake pipe of the main intake component 210, the gas will flow sequentially through the fourth connecting tee 210A, the second connecting tee 238, the first switching valve 231, the first intake tee 235A, the regulating valve 232, the first connecting tee 237, the second intake tee 236A, the second switching valve 234, the third connecting tee 239, and the fifth connecting tee 220A to form the first gas passage; when the gas source is connected to the non-interchangeable threaded joint (NIST) of the first backup intake component 235, the gas will flow sequentially through the first intake tee 235A, the regulating valve 232, and the first connecting tee 237. The second intake tee 236A, the second switching valve 234, the third connecting tee 239, and the fifth connecting tee 220A form a second gas passage (at this time, the first switching valve 231 of the sub-regulating assembly 230 in the operating state should be closed). When the gas source is connected to the non-interchangeable threaded joint (NIST) of the second backup intake component 236, the gas will flow sequentially through the second intake tee 236A, the second switching valve 234, the third connecting tee 239, and the fifth connecting tee 220A to form a third gas passage (at this time, the first switching valve 231 of the sub-regulating assembly 230 in the operating state should be closed). The other sub-regulating assembly 230 will only be activated when both the main intake component 210 and one of the sub-regulating assemblies 230 fail.

[0036] Furthermore, in embodiments including the base 300, the base 300 can be an integral structure, meaning the pressure regulating component 100 can be fixedly mounted on a single piece of the base 300; alternatively, the pressure regulating component 100 can be as follows: Figures 1-4 The illustrated base includes a split-type structure, 300.

[0037] In this embodiment, the base 300 may be provided with a plurality of position adjustment holes 310, and fasteners may pass through the position adjustment holes 310 and be fixedly connected to the base 300.

[0038] Preferably, such as Figure 1 , Figure 2 As shown, there are four fasteners 400, located on the four sides of the rectangle. The fasteners 400 can be, for example, clamps. Since each side of the rectangle formed by the pressure regulating member 200 is fixed by the fasteners 400, the degrees of freedom of the pressure regulating member 200 in the X, Y, and Z directions are restricted, allowing for a more stable installation of the pressure regulating member 200 and preventing unnecessary displacement of the pressure regulating member 200 relative to the base, wall, or furniture.

[0039] For example, Figures 1 to 4 The example shows a base 300 with a split structure, namely including a first base and a second base.

[0040] In one embodiment, the first base and the second base respectively secure the first spare air intake component 235 and the second spare air intake component 236 of the corresponding sub-adjustment assembly 230 from below via fasteners 400, that is, the arrangement of the first base and the second base is as follows: Figure 2 As shown, the first base and the second base are respectively located below the sides of the rectangle containing the two regulating valves. In another embodiment, the first base fixes two first spare air intake components 235 from below via fasteners 400, and the second base fixes two second spare air intake components 236 from below via fasteners 400, that is, in this case, the first base and the second base are respectively located below the sides of the rectangle containing the main air intake component and the air outlet component.

[0041] Preferably, the first base and the second base can be arranged in parallel, but the angle between them can also be adjusted according to actual installation requirements, for example, through the position adjustment hole 310.
