Description

Technical Field

[0001] This invention relates to the field of medical technology, and more particularly to an adaptive precision fluid management CRRT device. Background Technology

[0002] Continuous renal replacement therapy (CRRT), also known as continuous blood purification, is a blood purification technology that continuously and slowly removes water and solutes for 24 hours or nearly 24 hours a day through extracorporeal blood circulation to replace damaged kidney function. Adaptive precision fluid management CRRT devices are one type of this technology. However, existing adaptive precision fluid management CRRT devices generally do not easily control the temperature of the blood circulation purification environment to avoid large external temperature differences affecting the precision of fluid circulation and reducing the effectiveness of the device. Moreover, when pressure changes occur in the device, it is generally not easy to mark loose connections, making it difficult for medical staff to perform timely repairs, increasing safety hazards and reducing the effectiveness of the device. Furthermore, when safety hazards occur, the device generally does not easily issue alarms, requiring manual alarm handling, increasing the human burden and reducing the effectiveness of the device's alarms. Summary of the Invention

[0003] The problem solved by this invention is to provide an adaptive precision fluid management CRRT device that can control the temperature of the blood circulation purification environment, avoiding the influence of external temperature differences, ensuring the precision of fluid circulation, and improving the device's performance. Furthermore, when pressure changes occur, loose connections can be quickly marked, allowing medical personnel to perform rapid repairs, increasing the device's safety and performance. In addition, alarms can be triggered when safety hazards occur, eliminating the need for manual intervention, reducing the workload and further enhancing the device's effectiveness.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an adaptive precision fluid management CRRT device, comprising a continuous renal replacement therapy device body, a heat shield, a temperature control component, a marking component, and an alarm component. The heat shield is fixed to one outer wall of the continuous renal replacement therapy device body, the temperature control component is installed inside the heat shield, the marking component is installed on the outside of the heat shield, and alarm components are installed on both outer walls of the heat shield.

[0005] The temperature control assembly includes a heating tank, a temperature control circulation pipe, a first motor, a first gear, a fixed ring, a first slip ring, a second gear, a first threaded hole, a piston plate, a heater, and a first lead screw. The bottom end of the heat insulation cover has symmetrically arranged heating tanks. The top end of the heating tank is connected to the temperature control circulation pipe, which is folded and installed on the inner wall of the heat insulation cover. A piston plate is sealed inside the heating tank. A heater is installed on the outer wall of the top end of the piston plate. The bottom end of the piston plate is rotatably connected to the first lead screw, and the bottom end of the first lead screw extends to the outside of the heat insulation cover. The bottom end of the heating tank is connected to the fixed ring, and a first slip ring is slidably connected to the fixed ring. The bottom end of the first slip ring is fixedly connected to the second gear. The middle part of the second gear has a first threaded hole corresponding to the position of the first lead screw, and one side of the second gear is meshed with the first gear.

[0006] Preferably, a first motor is embedded in the bottom of the heat insulation cover, and the bottom of the output shaft of the first motor is fixed to the outer wall of the first gear.

[0007] Preferably, the marking assembly includes a second motor, a third gear, a guide rail, a first slider, a rack, a lifting frame, a first groove, a third motor, a second lead screw, a second slider, a second threaded hole, and a marking light. Guide rails are fixed to both outer walls of the heat insulation cover. A first slider is slidably connected within the guide rails. A rack is fixed to one outer wall of the first slider. A third gear is meshed on one outer wall of the rack. Second motors are embedded in both sides of the heat insulation cover, with one end of the output shaft of the second motor fixed to the outer wall of the third gear. A lifting frame is fixed to one outer wall of each of the two sliders. A first groove is provided within the lifting frame. A third motor is embedded in one inner wall of the first groove. A second lead screw is fixed to one end of the output shaft of the third motor, and the other end of the second lead screw is rotatably connected to the inner wall of the first groove. A second slider is slidably connected within the first groove. A second threaded hole is provided on the second slider corresponding to the position of the second lead screw. A marking light is installed on one outer wall of the second slider.

[0008] Preferably, the alarm assembly includes a support base, an alarm light, a first light-blocking cover, a second sliding groove, a second slip ring, a toothed ring, and a second light-blocking cover. Support bases are fixedly connected to the outer walls of both sides of the heat shield. An alarm light is installed on one side of the support base. A first light-blocking cover is fixedly connected to one side of the support base corresponding to the position of the alarm light. A second sliding groove is opened on the outer side of the support base. A second slip ring is slidably connected in the second sliding groove. A toothed ring is fixedly connected to the outer side of the second slip ring, and the outer side of the toothed ring is engaged with the outer wall of the rack. A second light-blocking cover is fixedly connected to one side of the toothed ring corresponding to the position of the first light-blocking cover.

[0009] Preferably, a maintenance groove is provided on one outer wall of the heat insulation cover, and a sealing cover is installed in the maintenance groove.

[0010] Preferably, a water supply pipe is connected through one side of the heat insulation cover, and a valve is embedded in the water supply pipe.

[0011] Preferably, the heater is of model XYWD-150 / SD1, and the heater is located on the inner wall of the heating tank.

[0012] Preferably, the second groove is annular in shape and is coated with lubricating oil.

[0013] The beneficial effects of this invention are as follows: A temperature control component is used. The heater is activated to heat the replacement fluid in the heating tank to a specified temperature. Then, the first motor is activated to rotate the first gear, which in turn drives the first slip rings on the two second gears to rotate in opposite directions along the fixed ring. Under the action of the first threaded hole, the first lead screw on one piston plate rises along the heating tank, while the other piston plate descends. The heated replacement fluid is squeezed by the piston plates, allowing the replacement fluid at the specified temperature to pass through the temperature-controlled circulation pipe and be temperature-controlled in the infusion tube. This allows for temperature control of the blood circulation purification environment, avoiding the influence of external temperature differences, ensuring the accuracy of fluid circulation, and improving the effectiveness of the equipment.

[0014] The device employs a marking assembly. Starting the second motor causes the third gear to rotate, and then, under the action of the rack, the first slider on the lifting frame rises and falls along the guide rail to a designated position. Next, starting the third motor causes the second lead screw to rotate, and then, under the action of the second threaded hole, the second slider moves along the first slide groove to a designated position. Finally, the marking light is activated to mark the location. When pressure changes occur in the equipment, loose connections can be quickly marked, allowing medical personnel to perform rapid repairs, increasing equipment safety and improving its effectiveness.

[0015] An alarm assembly is employed. Activating the alarm light on the support base illuminates the device, then starting the second motor to rotate the third gear. The first slider on the rack moves along the guide rail, causing the rack to drive the second sliding ring on the gear ring to rotate along the second sliding groove. This causes the second light-blocking cover on the gear ring to overlap and offset with the first light-blocking cover on the support base, causing the alarm light to flash. This provides an alarm alert when a safety hazard arises, eliminating the need for manual intervention, reducing labor burden, and improving the device's effectiveness. Attached Figure Description

By opening the sealing cover 7, the marked positions can be repaired through the maintenance groove 6, accelerating the repair process. A water supply pipe 8 is connected through one side of the heat shield 2. A valve 9 is embedded in the water supply pipe 8. When the continuous renal replacement therapy unit 1 is started to circulate and purify the patient's blood, the valve 9 is opened, and the replacement fluid is injected into the heating tank 301 through the water supply pipe 8. Then, the valve 9 is closed to seal the heating tank 301.

[0027] The temperature control assembly 3 includes a heating groove 301, a temperature control circulation pipe 302, a first motor 303, a first gear 304, a fixing ring 305, a first slip ring 306, a second gear 307, a first threaded hole 308, a piston plate 309, a heater 3010, and a first lead screw 3011. The bottom end of the heat insulation cover 2 is symmetrically provided with heating grooves 301, and the top end of the heating groove 301 is connected to the temperature control circulation pipe 302, which is folded and installed within the heat insulation cover. On the inner wall of the heat insulation cover 2, a piston plate 309 is sealed and installed inside the heating tank 301. A heater 3010 is installed on the outer wall of the top of the piston plate 309. A first lead screw 3011 is rotatably connected to the bottom end of the piston plate 309, and the bottom end of the first lead screw 3011 extends through to the outside of the heat insulation cover 2. A fixing ring 305 is connected through to the bottom end of the heating tank 301. A first slip ring 306 is slidably connected to the fixing ring 305. A second gear 30 is fixedly connected to the bottom end of the first slip ring 306. 7. A first threaded hole 308 is provided in the middle of the second gear 307 corresponding to the position of the first lead screw 3011. The first gear 304 is meshed and installed on one side of the second gear 307. The bottom end of the heat insulation cover 2 is embedded with a first motor 303, and the bottom end of the output shaft of the first motor 303 is fixed to the outer wall of the first gear 304. The first motor 303 is started to make the first gear 304 rotate, and then drive the first slip rings 306 on the two second gears 307 to rotate in opposite directions along the fixed ring 305. Then, under the action of the first threaded hole 308, the first lead screw 3011 on one of the piston plates 309 can be easily raised along the heating tank 301. The heater 3010 is model XYWD-150 / SD1, and the heater 3010 is located on the inner wall of the heating tank 301. According to the needs of the equipment, the heater 3010 is started to heat the displacement liquid in the heating tank 301 to the specified temperature, which improves the temperature control effect.

[0028] Working principle: First, the main body 1 of the continuous renal replacement therapy device is installed on the patient, and the blood circulation purification pipeline is connected to the patient's arteries and veins. The main body 1 of the continuous renal replacement therapy device is started to circulate and purify the patient's blood. At this time, valve 9 is opened, and then the replacement fluid is injected into the heating tank 301 through the water supply pipe 8. Then, valve 9 is closed to seal the heating tank 301. At this time, according to the needs of the equipment, the heater 3010 is started to heat the replacement fluid in the heating tank 301 to the specified temperature. Then, the first motor 303 is started to rotate the first gear 304, which in turn drives the two second gears 307. The first slip ring 306 rotates in the opposite direction along the fixed ring 305. Then, under the action of the first threaded hole 308, the first lead screw 3011 on one of the piston plates 309 rises along the heating tank 301, while the other piston plate 309 descends. The piston plate 309 squeezes the heated replacement fluid, causing the replacement fluid at the specified temperature to pass through the temperature-controlled circulation pipe 302 to control the temperature of the infusion pipe, and then flow into the other heating tank 301. This can control the temperature of the blood circulation purification environment, avoid the influence of external temperature differences, ensure the accuracy of liquid circulation, and improve the use effect of the equipment.

A lifting frame 406 is fixed to one side of the outer wall of the two first sliders 404. A first slide groove 407 is opened in the lifting frame 406. A third motor 408 is embedded in one side of the inner wall of the first slide groove 407. One end of the output shaft of the third motor 408 is fixed to a second lead screw 409, and the other end of the second lead screw 409 is rotatably connected to the inner wall of the first slide groove 407. A second slider 4010 is slidably connected in the first slide groove 407. A second threaded hole 4011 is opened on the second slider 4010 corresponding to the position of the second lead screw 409. A marker light 4012 is installed on one side of the outer wall of the second slider 4010.

[0031] When pressure changes occur in the infusion tubing, sensors on the main body 1 of the continuous renal replacement therapy device detect areas of insufficient pressure. Then, the second motor 401 is activated, causing the third gear 402 to rotate. Under the action of the rack 405, the first slider 404 on the lifting frame 406 rises and falls along the guide rail 403 to a designated position. Next, the third motor 408 is activated, causing the second lead screw 409 to rotate. Under the action of the second threaded hole 4011, the second slider 4010 moves along the first slide groove 407 to a designated position. Then, the marker light 4012 is activated to mark the location. When medical personnel arrive and identify the area requiring repair, the second motor 401 is activated, causing the third gear 402 to rotate. Under the action of the rack 405, the first slider 404 on the lifting frame 406 resets along the guide rail 403. Then, the sealing cover 7 is opened, and the marked location is repaired through the maintenance groove 6. When pressure changes occur in the equipment, loose connections can be quickly marked, allowing medical personnel to perform rapid repairs, increasing equipment safety and improving its effectiveness.

[0032] Example 3

[0033] See Figures 5-6 The alarm assembly 5 includes a support base 501, an alarm light 502, a first light shield 503, a second slide groove 504, a second slip ring 505, a toothed ring 506, and a second light shield 507. Support bases 501 are fixedly attached to the outer walls of both sides of the heat shield 2. An alarm light 502 is installed on one side of the support base 501.

A second light shield 507 is fixedly connected to one side of the toothed ring 506 corresponding to the position of the first light shield 503. The second sliding groove 504 is annular in shape and is coated with lubricating oil. The rack 405 drives the second sliding ring 505 on the toothed ring 506 to rotate along the second sliding groove 504, thereby increasing the lubrication between the second sliding ring 505 and the second sliding groove 504 and facilitating the rotation of the second sliding ring 505.

[0034] When a problem occurs with the equipment, the alarm light 502 on the support base 501 illuminates, then the second motor 401 is activated, causing the third gear 402 to rotate. The first slider 404 on the rack 405 moves along the guide rail 403, driving the second slip ring 505 on the gear ring 506 to rotate along the second slide groove 504. This causes the second light shield 507 on the gear ring 506 to overlap and offset with the first light shield 503 on the support base 501, causing the alarm light 502 to flash. This quickly alerts medical personnel when a safety hazard arises, eliminating the need for manual intervention, reducing workload, and improving equipment usability.
