Description

Technical Field

[0001] This application relates to the technical field of CRRT, and in particular to a CRRT waste liquid collection device. Background Technology

[0002] CRRT is a treatment technique that uses extracorporeal blood circulation to purify a patient's blood, thus replacing kidney function. CRRT equipment has a dialysate inlet and a waste fluid outlet. Dialysate flows into the CRRT equipment through the dialysate inlet to remove toxic substances from the patient's blood, while waste fluid is generated and flows out through the waste fluid outlet.

[0003] Currently, Chinese patent CN221624690U discloses a waste liquid transfer vehicle, including a frame, wheels at the bottom of the frame, a waste liquid collection tank fixed inside the frame, an open top for the waste liquid collection tank, a drainage component at the bottom of the waste liquid collection tank, and a waste liquid bag lifting device at the top of the frame.

[0004] Because the waste liquid collection tank is open, the CRRT waste liquid inside the tank will shake when the vehicle frame moves, causing some of the CRRT waste liquid to spill out of the collection tank. When a large amount of CRRT waste liquid spills out, it will pose a significant safety hazard. Utility Model Content

[0005] To reduce safety hazards, this application provides a CRRT waste liquid collection device.

[0006] This application provides a CRRT waste liquid collection device, which adopts the following technical solution:

[0007] A CRRT waste liquid collection device includes a vehicle body and a collection mechanism. The collection mechanism includes a barrel, a first cover, a second cover, and a transfer pipe. The barrel is placed on the vehicle body and has a collection cavity formed thereon. The first cover is fixedly disposed on the barrel, and the second cover is movably disposed on the barrel, with the first cover and the second cover together covering the collection cavity. The transfer pipe is disposed on the barrel and communicates with the collection cavity.

[0008] By adopting the above technical solution, the end of the transfer pipe furthest from the container is connected to the CRRT waste liquid bag. The waste liquid in the CRRT waste liquid bag then enters the collection chamber of the container through the transfer pipe. When the collection chamber of the container is filled with a certain amount of waste liquid, medical staff pull the vehicle, which moves the container to the waste liquid treatment area. The container is then removed from the vehicle, and the second cover is opened so that the medical staff can pour out the waste liquid in the collection chamber. When the container is being transported by the vehicle, the first and second covers cover the container, which blocks the waste liquid in the collection chamber, thus reducing the phenomenon of waste liquid shaking out of the collection chamber. Therefore, the collection mechanism can reduce the phenomenon of waste liquid spilling during transportation, thereby reducing safety hazards.

[0009] Optionally, the vehicle body is provided with a stabilizing mechanism, which includes stabilizing blocks and an adjusting component. Two stabilizing blocks are provided, and both stabilizing blocks are slidably disposed on the vehicle body. The adjusting component is disposed on the vehicle body, and both stabilizing blocks are connected to the adjusting component.

[0010] By adopting the above technical solution, when the barrel is located on the vehicle body, the adjustment component is activated, and the adjustment component drives the two stabilizing blocks to move in opposite directions, so that the two stabilizing blocks clamp the barrel; the stabilizing mechanism can improve the stability of the barrel on the vehicle body and reduce the phenomenon of waste liquid shaking in the collection chamber.

[0011] Optionally, the adjustment assembly includes a bidirectional lead screw and a drive member. The bidirectional lead screw is rotatably mounted on the vehicle body and passes through two of the stabilizing blocks, with the two stabilizing blocks respectively threaded to both ends of the bidirectional lead screw. The drive member is connected to one end of the bidirectional lead screw.

[0012] By adopting the above technical solution, the driving component drives the bidirectional lead screw to rotate, and the bidirectional lead screw will drive the two stabilizing blocks to move in opposite directions or away from each other. The set adjustment component has a simple structure and is easy to operate.

[0013] Optionally, the vehicle body is provided with a placement slot, and the barrel is engaged in the placement slot.

[0014] By adopting the above technical solution, when the vehicle is transporting the barrel, the barrel is placed in the placement slot of the vehicle, which can reduce the phenomenon of the barrel shaking on the vehicle; and when the barrel is in the placement slot, it can be quickly clamped by two stabilizing blocks.

[0015] Optionally, a transparent discharge pipe is inclinedly arranged on the barrel body, and the transparent discharge pipe is connected to the collection chamber; a pipe plug is snapped onto the transparent discharge pipe.

[0016] By adopting the above technical solution, medical staff can observe the transparent discharge tube to judge the collection status of waste liquid in the collection chamber. This avoids the phenomenon of excessive waste liquid collection or the waste liquid in the CRRT waste liquid bag not being able to be transferred to the collection chamber through the transfer tube when it is half transferred. Moreover, when emptying the waste liquid in the collection chamber, the tube plug can be removed, and then a portion of the waste liquid in the collection chamber can be poured out through the transparent discharge tube first, and then the waste liquid can be poured out through the part not covered by the second cover.

[0017] Optionally, the second cover is hinged to the barrel body, and the barrel body is provided with a fixing mechanism connected to the second cover. The fixing mechanism includes a first fixing block, a second fixing block, and a fixing component. The first fixing block is disposed on the second cover, and the second fixing block is disposed on the barrel body. The fixing component is disposed on the first fixing block and connected to the second fixing block.

[0018] By adopting the above technical solution, when the second cover and the first cover together cover the collection chamber, the second fixing block and the first fixing block are connected together by a fixing component. In this way, the first cover and the second cover will better block the waste liquid in the collection chamber. The fixing mechanism can improve the stability of the second cover and the first cover when covering the collection chamber, thereby better reducing the phenomenon of waste liquid spilling out of the collection chamber.

[0019] Optionally, the fixing component includes a fixing rod, a spring, and a limiting block. The fixing rod is slidably disposed on the first fixing block, and the second fixing block has a fixing groove that engages with the fixing rod. One end of the spring is connected to the fixing rod, and the other end is connected to the first fixing block. The limiting block is disposed on the fixing rod, and the first fixing block has a limiting groove that engages with the limiting block.

[0020] By adopting the above technical solution, when it is necessary for the second cover to no longer cover the collection cavity, medical staff first pull the limiting block, so that the limiting block drives the fixing rod to move, the fixing rod separates from the fixing groove, and then rotate the second cover to no longer cover the collection cavity.

[0021] Optionally, the barrel body is provided with a limiting component, which includes a limiting block, an elastic rope, and a limiting hook. The limiting block is disposed on the second cover body; the elastic rope is disposed on the barrel body; the limiting hook is disposed on the elastic rope; and the limiting block has a limiting hole that cooperates with the limiting hook.

[0022] By adopting the above technical solution, when the second cover does not cover the collection chamber, the limiting hook engages with the limiting hole on the limiting block. In this way, when the waste liquid in the collection chamber is poured out without the second cover covering it, the second cover will be fixed, reducing the phenomenon of the second cover shaking and affecting the pouring of waste liquid.

[0023] Optionally, the barrel body is provided with an exhaust hole, and a waterproof and breathable membrane is provided on the barrel body to cover the exhaust hole.

[0024] By adopting the above technical solution, the waterproof and breathable membrane can reduce the phenomenon of waste liquid flowing out through the vent.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The collection mechanism can reduce spillage of waste liquid during transportation, thereby reducing safety hazards;

[0027] 2. The stabilizing mechanism improves the stability of the tank on the vehicle body and reduces the phenomenon of waste liquid sloshing in the collection chamber;

[0028] 3. The fixing mechanism can improve the stability of the second cover and the first cover when covering the collection chamber, thereby better reducing the phenomenon of waste liquid spilling out of the collection chamber. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0036] This application discloses a CRRT waste liquid collection device.

[0037] refer to Figure 1 A CRRT waste liquid collection device includes a vehicle body 1, on which are mounted casters with brakes; a collection mechanism 2 and a stabilizing mechanism 3 are mounted on the vehicle body 1.

[0038] refer to Figure 2 and Figure 3 The vehicle body 1 is provided with a placement slot 11 and a lifting mechanism 7. The lifting mechanism 7 includes a lifting block 71 that is slidably connected in the placement slot 11. The vehicle body 1 is provided with a lifting motor 72, and a lifting gear 73 is keyed to the output shaft of the lifting motor 72. A lifting rack 74 that meshes with the lifting gear 73 is integrally provided on the lifting block 71.

[0039] Start the lifting motor 72. The output shaft of the lifting motor 72 drives the lifting gear 73 to rotate. The lifting gear 73 drives the lifting rack 74 to move, and the lifting rack 74 will drive the lifting block 71 to move.

[0040] refer to Figure 1 and Figure 3 The collection mechanism 2 includes a barrel 21 with a collection cavity formed on it; the collection cavity is placed in the placement slot 11 of the vehicle body 1 and abuts against the lifting block 71.

[0041] A stabilizing mechanism 3 is provided on the vehicle body 1. The stabilizing mechanism 3 includes two stabilizing blocks 31, both of which are slidably mounted on the vehicle body 1. An adjusting assembly 32 is provided on the vehicle body 1. The adjusting assembly 32 includes a bidirectional lead screw 321 rotatably connected to the vehicle body 1. The bidirectional lead screw 321 passes through the two stabilizing blocks 31, and the two stabilizing blocks 31 are threadedly connected to both ends of the bidirectional lead screw 321. A driving component 322 is provided on the vehicle body 1 and is connected to one end of the bidirectional lead screw 321. The driving component 322 can be a drive shaft or a drive motor.

[0042] When the barrel 21 is located in the placement slot 11, the drive component 322 drives the bidirectional lead screw 321 to rotate, and the bidirectional lead screw 321 drives the two stabilizing blocks 31 to move in opposite directions, so that the two stabilizing blocks 31 are pressed against the side wall of the barrel 21.

[0043] refer to Figure 1 and Figure 4A first cover 22 is fixedly connected to the barrel body 21, and a second cover 23 is hinged to the first cover 22. The first cover 22 and the second cover 23 together cover the collection cavity of the barrel body 21, and the part covered by the second cover 23 is the pouring opening of the barrel body 21. Vent holes are provided on both the first cover 22 and the barrel body 21, and a waterproof and breathable membrane 6 is provided at the vent holes.

[0044] A connecting pipe 27, communicating with the collection chamber, is fixedly connected to the barrel 21. A one-way valve is installed inside the connecting pipe 27, ensuring that liquid can only enter the collection chamber of the barrel 21 through the connecting pipe 27. An adapter pipe 24 is snapped onto the connecting pipe 27. The end of the adapter pipe 24 away from the barrel 21 is connected to the discharge pipe on the CRRT waste liquid bag. The existence of a discharge pipe on the CRRT waste liquid bag is existing technology and will not be described in detail here.

[0045] The waste liquid in the CRRT waste liquid bag enters the transfer pipe 24 through the discharge pipe, and then enters the collection chamber of the tank 21 through the transfer pipe 24 and the connecting pipe 27.

[0046] refer to Figure 4 and Figure 5 The second cover 23 is provided with a fixing mechanism 4 connected to the barrel 21. The fixing mechanism 4 includes a first fixing block 41 fixedly connected to the second cover 23, and a second fixing block 42 fixedly connected to the first cover 22.

[0047] The first fixing block 41 has a sliding hole, a through hole 412 communicating with the sliding hole, and two limiting grooves 411 communicating with the through hole 412. The limiting grooves 411 also communicate with the sliding hole. The second fixing block 42 has a fixing groove. The first fixing block 41 is provided with a fixing component 43, which includes a fixing rod 431 slidably connected in the sliding hole. The fixing rod 431 can engage with the fixing groove on the second fixing block 42. A rotating block 434 is rotatably connected to the fixing rod 431. The rotating block 434 is connected to a spring 432. One end of the spring 432 is connected to the rotating block 434 and the other end is connected to the first fixing block 41. A limiting block 433 is fixedly connected to the fixing rod 431. The limiting block 433 can engage with the limiting groove 411.

[0048] When the limiting block 433 is located in the limiting groove 411 on the side of the first fixing block 41 near the second fixing block 42, the spring 432 is in its normal state, and the fixing rod 431 is engaged with the fixing groove on the second fixing block 42. At this time, the second cover 23 and the first cover 22 together cover the collection cavity. When it is necessary to expose the pouring opening, that is, when the second cover 23 no longer covers the collection cavity, the medical staff first rotates the limiting block 433 so that the limiting block 433 is no longer located in the limiting groove 411, and then moves the limiting block 433. The limiting block 433 drives the fixing rod 431 to move away from the second fixing block 42, and the fixing rod 431 compresses the spring 432. When the limiting block 433 moves to the vicinity of the limiting groove 411 on the side of the first fixing block 41 away from the second fixing block 42, the fixing rod 431 separates from the fixing groove on the second fixing block 42, and then the limiting block 433 is rotated again so that the limiting block 433 is engaged with the limiting groove 411 on the side away from the second fixing block 42. Finally, rotate the second cover 23 so that it no longer covers the collection chamber.

[0049] refer to Figure 1 and Figure 4 A limiting component 5 is provided on the barrel body 21. The limiting component 5 includes a limiting block 51 fixedly connected to the second cover 23, and the limiting block 51 has a limiting hole. An elastic rope 52 is connected to the side wall of the barrel body 21. A limiting hook 53 is connected to one end of the elastic rope 52 away from the side wall of the barrel body 21. The limiting hook 53 cooperates with the limiting hole on the limiting block 51, that is, the limiting hook 53 can hook the limiting hole on the limiting block 51. A fixing ring 54 is fixedly connected to the side wall of the barrel body 21, and the limiting hook 53 can hook the limiting ring.

[0050] When the second cover 23 no longer covers the collection chamber and the pouring opening is exposed, the medical staff first separates the limiting hook 53 from the limiting ring, then pulls the limiting hook 53 to tighten the elastic rope 52, and then hooks the limiting hook 53 onto the limiting hole on the limiting block 51. This will fix the position of the second cover 23 and reduce the shaking of the second cover 23.

[0051] refer to Figure 1 and Figure 4 A transparent discharge pipe 25 is fixedly connected to the barrel body 21 at an angle, and the transparent discharge pipe 25 communicates with the collection chamber of the barrel body 21; a pipe plug 26 is snapped into the end of the transparent discharge pipe 25 away from the barrel body 21. The transparent discharge pipe 25 is offset from the second cover 23, that is, there is a certain angle between them. A handle and two hand buckles are connected to the barrel body 21.

[0052] To better detect the amount of waste liquid in the collection chamber, a liquid level sensor can be installed in the collection chamber, and an alarm connected to the liquid level sensor can be installed on the tank body 21.

[0053] The implementation principle of the CRRT waste liquid collection device in this application embodiment is as follows: the waste liquid generated by CRRT will enter the CRRT waste liquid bag; within a certain time period, medical staff push the vehicle 1 to the vicinity of the CRRT equipment, and then connect one end of the transfer pipe 24 to the connecting pipe 27 on the tank 21 and the other end to the discharge pipe on the CRRT waste liquid bag. In this way, the waste liquid in the CRRT waste liquid enters the transfer pipe 24 through the discharge pipe and then enters the collection chamber of the tank 21 through the connecting pipe 27.

[0054] When enough waste liquid has been collected in the collection chamber of the container 21, the transfer tube 24 is separated from the CRRT waste liquid bag, and then the medical staff pulls the vehicle 1 to transfer the container 21 to the waste liquid treatment area.

[0055] First, the medical staff uses the drive unit 322 to rotate the bidirectional lead screw 321, so that the two stabilizing blocks 31 no longer abut against the side wall of the barrel 21; then, the lifting block 71 moves the barrel 21, so that the barrel 21 separates from the placement slot 11 on the vehicle body 1 and is no longer located in the placement slot 11; then, the barrel 21 is transferred off the vehicle body 1. The medical staff first makes the tube plug 26 no longer jammed with the transparent discharge tube 25, then holds the handle with one hand and the handle with the other hand, so that a portion of the waste liquid in the collection chamber of the barrel 21 is poured out through the transparent discharge tube 25; then, the fixing rod 431 is separated from the fixing slot on the second fixing block 42, and the second cover 23 is rotated so that the second cover 23 no longer covers the collection chamber, then the limiting hook 53 hooks the limiting port on the limiting block 51 on the second cover 23, and finally, the medical staff pours out the waste liquid in the collection chamber through the pouring port.

[0056] Finally, medical staff can clean and disinfect the transfer pipe 24 and the tank 21.

[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
