Description

Technical Field

[0001] This invention relates to the field of liquid oxygen technology, specifically to an alarm and monitoring device for the oxygen supply of a hospital liquid oxygen center with a flow interruption function. Background Technology

[0002] Liquid oxygen central supply is the mainstream method of centralized oxygen supply in modern hospitals. Its alarm monitoring system is the core of ensuring oxygen supply safety. The system monitors pressure, flow, liquid level and oxygen concentration in real time through sensors. Combined with an intelligent control platform, it automatically alarms and activates emergency procedures when there is abnormal pressure, leakage or insufficient storage tank volume, so as to ensure stable and reliable oxygen supply and meet the continuous needs of medical treatment.

[0003] Patent CN215083657U discloses a hospital liquid oxygen center oxygen supply alarm monitoring device with flow interruption function, including an oxygen supply main pipe, one end of which is fixedly connected to two oxygen supply branch pipes, and one end of each oxygen supply branch pipe is fixedly connected to a terminal oxygen supply machine. This hospital liquid oxygen center supply alarm and monitoring device with flow interruption function, compared with existing ordinary hospital liquid oxygen center supply alarm and monitoring devices, has the following advantages: When the oxygen pressure sensor detects excessively high oxygen pressure, it converts the pressure signal into an electrical signal and transmits it to the drive motor and alarm. Simultaneously, the drive motor, through transmission gears and adjusting screws, transmits power to the sealing block, causing it to promptly interrupt the oxygen flow and prevent harm to patients. The frustum-shaped sealing block controls the opening and closing of the oxygen orifice, thus regulating the oxygen flow rate inside the supply pipe and ensuring the oxygen pressure remains within normal limits. While this device solves the aforementioned problems, it still has limitations in effectively and quickly interrupting the flow when equipment malfunctions. Furthermore, it is difficult to determine the flow pressure of liquid oxygen during transportation, and the smooth flow of liquid oxygen during transport can easily lead to uneven distribution. Therefore, this hospital liquid oxygen center supply alarm and monitoring device with flow interruption function is proposed to address these issues. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a hospital liquid oxygen center oxygen supply alarm monitoring device with flow interruption function, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a hospital liquid oxygen center oxygen supply alarm monitoring device with flow interruption function, including a mold shell, a display screen is provided on the outer wall of the mold shell, a flow diversion mechanism is provided on the top of the mold shell, a flow blocking mechanism is provided on the outer wall of the mold shell, and a detection mechanism is provided on the bottom of the mold shell. Preferably, the diversion mechanism includes a main flow pipe, a fixed plate, a spiral rod, and a transmission vertical rod. The main flow pipe is fixedly connected to the inner wall of the mold shell, the fixed plate is fixedly connected to the inner wall of the main flow pipe, the spiral rod is rotatably connected to the inner wall of the fixed plate, and the transmission vertical rod is rotatably connected to the inner wall of the main flow pipe. The transmission vertical rod and the spiral rod are connected by a bevel gear set.

[0006] Preferably, the diversion mechanism further includes a torsion spring cap, a limiting plate, a transmission and blocking rod, and a blocking ring. The torsion spring cap is fixedly connected to the outer wall of the transmission vertical rod, the limiting plate is movably connected to the outer circumferential surface of the spiral rod, the transmission and blocking rod is fixedly connected to the outer wall of the limiting plate, the blocking ring is fixedly connected to the outer wall of the transmission and blocking rod, and the blocking ring is slidably connected to the inner wall of the main flow pipe.

[0007] Preferably, the diversion mechanism further includes a limiting strip, a bifurcation rod, a rotating shaft, a torsion cap, and a branch pipe. The limiting strip is fixedly connected to the outer wall of the blocking ring, the bifurcation rod is fixedly connected to the bottom of the main flow pipe, the rotating shaft is rotatably connected to the inner wall of the mold shell, the torsion cap is fixedly connected to the outer wall of the rotating shaft, the branch pipe is fixedly connected to the bottom of the bifurcation rod, and the limiting strip is slidably connected to the inner wall of the main flow pipe. During operation, liquid oxygen enters the device through a diversion mechanism. Guided by a bifurcation rod, it is separated into branch pipes and then output again. In case of malfunction, such as pipe blockage or abnormal pressure, rotating the torsion spring cap rotates the transmission rod. This rotation, via a bevel gear set, drives the spiral rod. The spiral rod's rotation, through its spiral grooves, causes a limiting plate to move downwards under the constraint of the limiting strip and the main flow pipe. The blocking ring moves downwards into the bifurcation rod, allowing manual shut-off of liquid oxygen delivery to prevent accidents. When parts need replacement, the liquid oxygen source can be manually cut off, ensuring operator safety. Rotating the torsion cap also rotates the rotating shaft, which in turn rotates the torsion cap. This allows for manual adjustment of the liquid oxygen flow rate within the branch pipes. This step allows for fine-tuning of the flow rate during device start-up, shutdown, or fluctuations in operating conditions, preventing equipment malfunctions due to sudden flow changes.

[0008] Preferably, the flow-blocking mechanism further includes a reciprocating lead screw, a limiting rod plate, and a cross spring. The reciprocating lead screw is fixedly connected to the inner wall of the rotating shaft, the limiting rod plate is fixedly connected to the inner wall of the reciprocating lead screw, and the cross spring is fixedly connected to the outer wall of the limiting rod plate.

[0009] Preferably, the flow-blocking mechanism further includes a spring retaining ring, a sliding vertical rod, and a horizontal movable pin. The spring retaining ring is fixedly connected to the outer wall of the horizontal leaf spring, the sliding vertical rod is slidably connected to the outer wall of the screw rod, the screw rod and the sliding vertical rod are connected by a spring, the sliding vertical rod is located on the movement trajectory of the limiting plate, the spring retaining ring is located on the movement trajectory of the sliding vertical rod, the horizontal movable pin is movably connected to the outer circumferential surface of the reciprocating lead screw, and the horizontal movable pin is slidably connected to the inner wall of the mold shell.

[0010] Preferably, the flow-blocking mechanism further includes a bottom limiting plate, an extension tube, a transverse transmission rod, a plug, and a gripping column. The bottom limiting plate is fixedly connected to the bottom of the mold shell, the extension tube is fixedly connected to the outer wall of the branch tube, the transverse transmission rod is slidably connected to the inner wall of the extension tube, the plug is fixedly connected to the outer wall of the transverse transmission rod, the gripping column is fixedly connected to the outer wall of the transverse transmission rod, and the branch tube is located on the movement trajectory of the plug. Before the flow is cut off, rotating the rotating shaft adjusts the torsion cap to the lateral direction. When the torsion cap is lateral, it can completely block the branch pipe. Then, rotating the screw rod drives the limiting plate downward through the spiral groove on the circumferential surface. The downward movement of the limiting plate compresses and drives the sliding vertical rod downward. During the movement, the sliding vertical rod enters the interior of the spring ring, thereby achieving the effect of immediate flow cut-off. This prevents any remaining liquid oxygen from leaking out during the flow cut-off. Immediately cutting off the liquid oxygen supply can prevent the remaining liquid oxygen from leaking out and causing the danger of low-temperature freezing, fire, and explosion. In use, whether it is for patients to temporarily stop oxygen use in medical scenarios or for process switching and equipment maintenance in industrial scenarios, immediate flow cut-off can prevent liquid oxygen waste. During the rotation of the rotating shaft, the reciprocating screw moves. During the movement of the reciprocating screw, the horizontal movable needle moves back and forth through the cross spiral groove on the circumferential surface. During the movement, the horizontal movable needle points to the scale inside the bottom limiting plate, allowing the operator to intuitively see the flow rate of liquid oxygen inside the branch pipe, thus facilitating manual operation of the device.

[0011] Preferably, the detection mechanism further includes a sliding limiting ring, a baffle column, and a baffle brush. The sliding limiting ring is fixedly connected to the inner wall of the mold shell, the baffle column is fixedly connected to the inner wall of the sliding limiting ring, and the baffle brush is fixedly connected to the outer wall of the baffle column.

[0012] Preferably, the detection mechanism further includes a spring button, an electrical connecting ring, and a photomask ring. The spring button is slidably connected to the inner wall of the bottom limit plate, the electrical connecting ring is electrically connected to the inner wall of the spring button, and the photomask ring is fixedly connected to the bottom of the bottom limit plate.

[0013] Preferably, the detection mechanism further includes a warning light and a glass cover, wherein the warning light is fixedly connected to the inner wall of the photomask ring, the glass cover is fixedly connected to the outer wall of the photomask ring, and the electrical connecting ring is electrically connected to the inner wall of the warning light. The simultaneous presence of multiple branch pipes prevents oxygen supply interruptions caused by a single branch failure. In situations where maintenance is required during operation and oxygen supply interruption is unacceptable, the gripping column above the pipeline requiring maintenance is pushed inwards. The movement of the gripping column moves the transverse rod inwards, which in turn moves the plug into the branch pipe, thus blocking it. Meanwhile, the other two branch pipes continue to supply liquid oxygen to the pipeline below, facilitating offline maintenance of the faulty branch without requiring a complete shutdown. During liquid oxygen transport, a sliding retaining ring is inserted into the device, followed by a turbulence column. This column contacts the turbulence brush during liquid oxygen flow, changing the oxygen flow from laminar to turbulent, promoting uniform mixing and preventing uneven concentration distribution. When the internal liquid oxygen pressure becomes excessive, causing the rotating shaft to move, the transverse needle moves. During this movement, the needle presses a trigger, activating an alarm to prevent the internal pipeline from becoming blocked due to excessive pressure and potentially bursting.

[0014] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This hospital liquid oxygen center supply alarm monitoring device with flow interruption function, through the cooperation of a blocking ring, rotating shaft, spiral rod, and torsion spring cap, separates oxygen into the branch pipe and then outputs it through the branch pipe. When the equipment malfunctions, such as pipeline blockage or abnormal pressure, the rotating torsion spring cap drives the transmission vertical rod to rotate. During the rotation of the transmission vertical rod, the spiral rod is driven to rotate through the bevel gear set. During the rotation of the spiral rod, the spiral groove on the circumferential surface drives the limiting plate to move downward under the limit of the limiting bar and the main pipe. The blocking ring moves downward to the inside of the branch rod, which can manually cut off the liquid oxygen supply, thereby avoiding safety accidents. During the rotation of the rotating shaft, the torsion cap is driven to rotate. During the rotation of the torsion cap, the liquid oxygen flow rate inside the branch pipe can be manually adjusted. This step can fine-tune the flow rate when the equipment starts or stops or the operating conditions fluctuate, avoiding equipment failure due to sudden changes in flow rate.

[0015] 2. This hospital liquid oxygen center supply alarm monitoring device with flow interruption function, through the cooperation of a sliding vertical rod, a limiting plate, a horizontal movable needle, and a reciprocating screw, uses the cross-shaped spiral groove on the circumferential surface of the reciprocating screw to drive the horizontal movable needle to move back and forth. During its movement, the horizontal movable needle points to the scale inside the bottom limiting plate, allowing the operator to intuitively see the flow rate of liquid oxygen inside the branch pipe, thus facilitating manual operation of the device. The rotating screw rod drives the limiting plate downward through the spiral groove on the circumferential surface. The downward movement of the limiting plate compresses and drives the sliding vertical rod downward. During its movement, the sliding vertical rod enters the interior of the spring ring, thereby immediately interrupting the flow and preventing any remaining liquid oxygen from leaking out. Immediately cutting off the liquid oxygen supply can prevent the leakage of residual liquid oxygen, thus preventing the danger of low-temperature frostbite, fire, and explosion. In use, whether it is for patients temporarily stopping oxygen use in medical settings or for process switching and equipment maintenance in industrial settings, immediate flow interruption can prevent the waste of liquid oxygen.

[0016] 3. This hospital liquid oxygen center supply alarm and monitoring device with flow interruption function, through the cooperation of the horizontal movable needle warning light and the shaft, contacts the turbulence brush during the liquid oxygen flow, thereby changing the oxygen flow from laminar to turbulent, promoting uniform mixing of liquid oxygen and avoiding uneven distribution of liquid oxygen concentration. When the liquid oxygen pressure inside the device is too high and the rotating shaft moves, the horizontal movable needle will move. During the movement, the horizontal movable needle will press the trigger button, causing the warning light to sound an alarm, preventing the internal pipeline from becoming blocked due to excessive pressure. Failure to detect this in time could lead to pipeline rupture. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-7 One embodiment of the present invention is: a hospital liquid oxygen center oxygen supply alarm monitoring device with flow interruption function, including a mold shell 1, a display 2 provided on the outer wall of the mold shell 1, a flow diversion mechanism 3 provided on the top of the mold shell 1, a flow blocking mechanism 4 provided on the outer wall of the mold shell 1, and a detection mechanism 5 provided on the bottom of the mold shell 1. The diversion mechanism 3 includes a main flow pipe 301, a fixing plate 302, a spiral rod 303, and a transmission vertical rod 304. The main flow pipe 301 is fixedly connected to the inner wall of the mold shell 1, the fixing plate 302 is fixedly connected to the inner wall of the main flow pipe 301, the spiral rod 303 is rotatably connected to the inner wall of the fixing plate 302, and the transmission vertical rod 304 is rotatably connected to the inner wall of the main flow pipe 301. The transmission vertical rod 304 and the spiral rod 303 are connected by a bevel gear set.

[0021] The diversion mechanism 3 also includes a torsion spring cap 305, a limiting plate 306, a transmission blocking rod 307, and a blocking ring 308. The torsion spring cap 305 is fixedly connected to the outer wall of the transmission vertical rod 304, the limiting plate 306 is movably connected to the outer circumferential surface of the spiral rod 303, the transmission blocking rod 307 is fixedly connected to the outer wall of the limiting plate 306, the blocking ring 308 is fixedly connected to the outer wall of the transmission blocking rod 307, and the blocking ring 308 is slidably connected to the inner wall of the main flow pipe 301.

[0022] The diversion mechanism 3 also includes a limiting strip 309, a bifurcation rod 310, a rotating shaft 311, a torsion cap 312, and a branch pipe 313. The limiting strip 309 is fixedly connected to the outer wall of the blocking ring 308, the bifurcation rod 310 is fixedly connected to the bottom of the main flow pipe 301, the rotating shaft 311 is rotatably connected to the inner wall of the mold shell 1, the torsion cap 312 is fixedly connected to the outer wall of the rotating shaft 311, the branch pipe 313 is fixedly connected to the bottom of the bifurcation rod 310, and the limiting strip 309 is slidably connected to the inner wall of the main flow pipe 301. This hospital liquid oxygen center oxygen supply alarm monitoring device with flow interruption function separates oxygen into the branch pipe 313 and then outputs it through the branch pipe 313. When the equipment malfunctions, such as pipeline blockage or abnormal pressure, rotating the torsion spring cap 305 drives the transmission vertical rod 304 to rotate. During the rotation of the transmission vertical rod 304, the spiral rod 303 is driven to rotate through the bevel gear set. During the rotation of the spiral rod 303, the limiting plate 306 is driven to move downward under the limitation of the limiting bar 309 and the main pipe 301. The blocking ring 308 moves downward to the inside of the branch rod 310, which can manually cut off the liquid oxygen supply, thereby avoiding safety accidents. During the rotation of the rotating shaft 311, the torsion cap 312 is driven to rotate. During the rotation of the torsion cap 312, the liquid oxygen flow rate inside the branch pipe 313 can be manually adjusted. This step can fine-tune the flow rate when the equipment starts or stops or the operating conditions fluctuate, avoiding equipment failure due to sudden changes in flow rate.

[0023] The flow blocking mechanism 4 also includes a reciprocating lead screw 401, a limiting plate 402, and a transverse spring 403. The reciprocating lead screw 401 is fixedly connected to the inner wall of the rotating shaft 311, the limiting plate 402 is fixedly connected to the inner wall of the reciprocating lead screw 401, and the transverse spring 403 is fixedly connected to the outer wall of the limiting plate 402.

[0024] The flow-blocking mechanism 4 also includes a spring retaining ring 404, a sliding vertical rod 405, and a horizontal movable pin 406. The spring retaining ring 404 is fixedly connected to the outer wall of the horizontal leaf spring 403. The sliding vertical rod 405 is slidably connected to the outer wall of the screw rod 303. The screw rod 303 and the sliding vertical rod 405 are connected by a spring. The sliding vertical rod 405 is located on the movement trajectory of the limiting plate 306. The spring retaining ring 404 is located on the movement trajectory of the sliding vertical rod 405. The horizontal movable pin 406 is movably connected to the outer circumferential surface of the reciprocating screw 401 and is slidably connected to the inner wall of the mold shell 1.

[0025] The flow-blocking mechanism 4 also includes a bottom limit plate 407, an extension tube 408, a transverse transmission rod 409, a plug plate 410, and a gripping column 411. The bottom limit plate 407 is fixedly connected to the bottom of the mold shell 1, the extension tube 408 is fixedly connected to the outer wall of the branch tube 313, the transverse transmission rod 409 is slidably connected to the inner wall of the extension tube 408, the plug plate 410 is fixedly connected to the outer wall of the transverse transmission rod 409, the gripping column 411 is fixedly connected to the outer wall of the transverse transmission rod 409, and the branch tube 313 is located on the movement trajectory of the plug plate 410. This hospital liquid oxygen center supply alarm monitoring device with flow interruption function uses a reciprocating screw 401 to drive a horizontal movable needle 406 to reciprocate through a cross-shaped spiral groove on the circumferential surface. During its movement, the horizontal movable needle 406 points to the scale inside the bottom limit plate 407, allowing operators to visually observe the flow rate of liquid oxygen within the branch pipe 313, facilitating manual operation. A rotating screw 303, through the spiral groove on the circumferential surface, drives the limiting plate 306 downwards. The downward movement of the limiting plate 306 compresses and drives the sliding vertical rod 405 downwards. During its movement, the sliding vertical rod 405 enters the interior of the spring coil 404, thus immediately interrupting the flow and preventing any remaining liquid oxygen from leaking out. Immediately cutting off the liquid oxygen supply prevents residual liquid oxygen from leaking out, thus avoiding the dangers of low-temperature frostbite, fire, and explosion. Whether in medical settings where patients temporarily stop oxygen use, or in industrial settings during process switching or equipment maintenance, immediate flow interruption prevents liquid oxygen waste.

[0026] Working principle: During operation, liquid oxygen enters the device through the diversion mechanism 3. Guided by the bifurcation rod 310, it is separated into the branch pipe 313, which then distributes it out. When an abnormality occurs, such as pipe blockage or abnormal pressure, the rotating torsion spring cap 305 drives the transmission vertical rod 304 to rotate. During this rotation, the transmission vertical rod 304 drives the spiral rod 303 to rotate via the bevel gear set. As the spiral rod 303 rotates, the spiral groove on its circumferential surface causes the limiting plate 306 to move downwards under the constraint of the limiting strip 309 and the main flow pipe 301. The blocking ring 308 moves downwards into the inside of the branch rod 310, which can manually cut off the liquid oxygen supply, thereby avoiding safety accidents. When the equipment needs to replace parts, the liquid oxygen source can be manually cut off, thereby ensuring the safety of operators. The rotating nut 312 drives the rotating shaft 311 to rotate. During the rotation of the rotating shaft 311, the nut 312 is driven to rotate. During the rotation of the nut 312, the liquid oxygen flow rate inside the branch pipe 313 can be manually adjusted. This step can fine-tune the flow rate when the equipment starts up or stops or when the operating conditions fluctuate, avoiding equipment failure due to sudden changes in flow rate.

[0027] Before the flow is cut off, rotating the rotating shaft 311 adjusts the torsion cap 312 to the lateral direction. When the torsion cap 312 is lateral, it can completely block the branch pipe 313. Then, rotating the spiral rod 303 drives the limiting plate 306 downward through the spiral groove on the circumferential surface. The downward movement of the limiting plate 306 compresses and drives the sliding vertical rod 405 downward. During the movement, the sliding vertical rod 405 enters the interior of the spring ring 404, thereby achieving the effect of immediate flow cut-off. This prevents any remaining liquid oxygen from leaking out during the flow cut-off. Immediately cutting off the liquid oxygen supply can prevent the leakage of remaining liquid oxygen during the flow cut-off, thus preventing low-temperature freezing damage. The device eliminates the risk of fire and explosion. Whether in a medical setting where patients temporarily stop oxygen use or in an industrial setting where processes are switched or equipment is repaired, the immediate interruption of the flow can prevent the waste of liquid oxygen. During the rotation of the rotating shaft 311, the reciprocating screw 401 is moved. During the movement of the reciprocating screw 401, the cross-shaped spiral groove on the circumferential surface drives the horizontal movable needle 406 to move back and forth. During the movement, the horizontal movable needle 406 points to the scale inside the bottom limit plate 407, so that the operator can intuitively see the flow rate of liquid oxygen inside the branch pipe 313, thus facilitating manual operation of the device.

[0028] Please see Figures 1-7 Based on the above embodiments, in another embodiment of the present invention, the detection mechanism 5 further includes a sliding limiting ring 501, a turbulence column 502, and a turbulence brush 503. The sliding limiting ring 501 is fixedly connected to the inner wall of the mold shell 1, the turbulence column 502 is fixedly connected to the inner wall of the sliding limiting ring 501, and the turbulence brush 503 is fixedly connected to the outer wall of the turbulence column 502.

[0029] The testing mechanism 5 also includes a spring button 504, an electrical connecting ring 505, and a photomask ring 506. The spring button 504 is slidably connected to the inner wall of the bottom limit plate 407, the electrical connecting ring 505 is electrically connected to the inner wall of the spring button 504, and the photomask ring 506 is fixedly connected to the bottom of the bottom limit plate 407.

[0030] The testing unit 5 also includes a warning light 507 and a glass cover 508. The warning light 507 is fixedly connected to the inner wall of the photomask ring 506, and the glass cover 508 is fixedly connected to the outer wall of the photomask ring 506. The electrical connecting ring 505 is electrically connected to the inner wall of the warning light 507. This hospital liquid oxygen center supply alarm and monitoring device with flow interruption function contacts the turbulence brush 503 during liquid oxygen flow, thereby changing the oxygen flow from laminar to turbulent, promoting uniform mixing of liquid oxygen and avoiding uneven distribution of liquid oxygen concentration. When the liquid oxygen pressure inside the device is too high and the rotating shaft 311 moves, the transverse movable needle 406 will move. During the movement, the transverse movable needle 406 presses the spring button 504, thereby triggering the alarm light 507, preventing the internal pipeline from becoming blocked due to excessive pressure and potentially rupturing due to pipeline rupture if not detected in time.

[0031] Working principle: The simultaneous existence of multiple branch pipes 313 prevents oxygen supply interruption due to a single branch failure. When maintenance is required during operation and oxygen supply interruption is not permitted, the gripping column 411 above the pipeline requiring maintenance is pushed into the device. The movement of the gripping column 411 moves the transverse rod 409 into the device, which in turn moves the plug 410 into the branch pipe 313, thus blocking it. Meanwhile, the two branch pipes 313 at the other end continue to supply liquid oxygen to the pipeline below, facilitating maintenance of the faulty branch. Offline maintenance is possible without a complete shutdown. During liquid oxygen transport, the sliding retaining ring 501 is inserted into the device, followed by the turbulence column 502. As the liquid oxygen flows, it contacts the turbulence brush 503, changing the oxygen flow from laminar to turbulent, promoting uniform mixing and preventing uneven concentration distribution. When the internal liquid oxygen pressure becomes excessive, causing the rotating shaft 311 to move, the transverse needle 406 moves, pressing the spring button 504 and triggering the warning light 507 to sound an alarm, preventing internal pipe blockage due to excessive pressure and potential pipe rupture if not detected in time.

[0032] This invention provides a hospital liquid oxygen center oxygen supply alarm monitoring device with flow interruption function. Many methods and approaches exist for implementing this technical solution; the above are merely preferred embodiments of this invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this invention, and these improvements and modifications should also be considered within the scope of protection of this invention. All components not explicitly stated in this embodiment can be implemented using existing technologies.
