Description

Technical Field

[0001] This invention relates to the field of nursing equipment technology, and more specifically, to an adjustable nursing cart for blood purification nursing. Background Technology

[0002] Blood purification refers to the process of drawing a patient's blood out of the body and using a purification device to remove certain pathogenic substances, thereby purifying the blood and treating diseases. The main methods of blood purification include hemodialysis, hemofiltration, hemoperfusion, plasma exchange, and immunoadsorption.

[0003] However, existing adjustment nursing carts cannot easily adjust the interface position of the waste liquid collection pipe before collecting dialysis waste liquid, which makes it easy for the waste liquid collection pipe to bend in some places during the collection process, resulting in reduced waste liquid collection efficiency and thus reducing the effectiveness of the device. Summary of the Invention

[0004] This invention provides an adjustable nursing cart for blood purification nursing, which solves the problem in the prior art where the interface position of the waste fluid collection tube is inconvenient to adjust before collecting dialysis waste fluid. This causes the waste fluid collection tube to bend excessively in some places during the collection process, resulting in reduced waste fluid collection efficiency and thus reduced device effectiveness.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An adjustable nursing cart for blood purification includes a base plate and a flow guide seat. The flow guide seat is equipped with a flow guide assembly, which includes a guide rod horizontally positioned at the top of the flow guide seat. Multiple flow guide holes are formed on the flow guide seat along the extension direction of the guide rod. A conduit passes through the guide rod, and the conduit is vertically aligned with any of the flow guide holes. A flow guide block is attached to the top of the conduit. Multiple drainage holes are evenly formed on the flow guide block. Multiple sealing plugs connected by connecting straps are provided on one side of the flow guide block, and each sealing plug is engaged within one of the drainage holes.

[0012] The principle and beneficial effects of this technical solution:

[0013] (1) The flow guiding component set in this invention can be used in conjunction with the adjustment component. When collecting dialysis waste fluid generated by different purification methods, it can adapt to the specific situation of the patient to recover the waste dialysis fluid. By adjusting the position and angle of the waste fluid pipe interface, the probability of pipe bending and blockage during the discharge of waste dialysis fluid is reduced, and the effectiveness of the device is improved.

[0014] (2) The positioning component provided in this invention can lock the position of the catheter to prevent slippage during the flow of the catheter. When the positioning effect of the positioning component is released, hold the handle provided at one end of the crossbar and turn the handle to make the positioning rod disengage from the catheter so that the catheter can be moved. When it is necessary to re-lock the position of the catheter, release the handle and the first spring in the positioning component will drive the other components to reset.

[0015] (3) The clamping component provided in this invention can connect the waste liquid hose to the waste liquid tank. When the clamping component needs to loosen the waste liquid hose, the two connecting plates are rotated along the fixed base at the same time to loosen the waste liquid hose. At this time, the waste liquid hose can be removed. Medical staff can then clean or disinfect the empty waste liquid tank for reuse. For those that cannot be reused, they can be treated as medical waste after special treatment. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0022] Example:

[0023] like Figures 1 to 4As shown, the present invention provides an adjustable nursing cart for blood purification nursing, including a base plate 3 and a flow guide seat 27. The flow guide seat 27 is provided with a flow guide assembly, which includes a guide rod 19 horizontally arranged at the top of the flow guide seat 27. Multiple flow guide holes 4 are opened on the flow guide seat 27 along the extension direction of the guide rod 19. A conduit 17 is passed through the guide rod 19. The conduit 17 is vertically aligned with any of the flow guide holes 4. A flow guide block 16 is connected to the top of the conduit 17. Multiple drainage holes are evenly opened on the flow guide block 16. Multiple sealing plugs 15 connected by connecting straps 14 are provided on one side of the flow guide block 16. Each sealing plug 15 is locked in a drainage hole. A positioning assembly is provided on one side of the flow guide seat 27. An adjustment assembly is provided at the bottom of the flow guide seat 27.

[0024] The flow guiding component can be used in conjunction with the adjustment component to collect dialysis waste fluid generated by different purification methods, adapting to the specific needs of patients and recovering waste dialysis fluid. When using the device for waste fluid collection, first adjust the height of the flow guiding seat 27 using the adjustment component, driving the hydraulic rod 2812 to extend and retract. Since both ends of the hydraulic rod 2812 are hinged to the flow guiding seat 27 and the base plate 3 respectively, and a pair of parallel locking plates 30 rotatably connected to the bottom end of the flow guiding seat 27 are engaged within a pair of hinged plate sleeves 29 on the base plate 3, the flow guiding seat 27 always remains parallel to the base plate 3. Manually pressing down or lifting the hydraulic rod 2812 changes its angle, and by coordinating the extension and retraction of the hydraulic rod 2812, the position of the flow guiding seat 27 in the vertical plane can be adjusted. After the guide seat 27 is adjusted into place, the position restriction of the guide seat 27 by the positioning component is released. The catheter 17 is slid along the guide rod 19 until the catheter 17 slides to the appropriate position. At this time, the catheter 17 is aligned with the corresponding guide hole 4 at the appropriate position. At the same time, the locking of the position of the catheter 17 by the positioning component is restored. Finally, according to the specific angle of the patient's waste fluid tube, a drainage hole with an appropriate angle is selected on the guide block 16. After selecting the drainage hole, the sealing plug 15 stuck on the drainage hole is removed by the connecting strap 14. Then, the free end of the patient's waste fluid tube is connected to the drainage hole. This invention reduces the probability of pipe bending and blockage during the discharge of waste dialysis fluid by adjusting the position and angle of the waste fluid tube interface, thereby improving the effectiveness of the device.

[0025] like Figure 1 and Figure 2 As shown, the positioning assembly includes several pairs of side plates 13 arranged on one side of the flow guide seat 27. Each pair of side plates 13 is hinged with a pressure rod 12. The top of the pressure rod 12 is rotatably connected to a rotating seat 11. A positioning rod 18 is connected to one side of the rotating seat 11. Several end plates 31 are arranged at the top of the flow guide seat 27. Each positioning rod 18 passes through an end plate 31. The end plate 31 is connected to the rotating seat 11 by a first spring 10. The free end of the positioning rod 18 is locked on the guide tube 17. The bottom ends of all the pressure rods 12 are connected to a horizontal shaft. A handle 6 is arranged at one end of the horizontal shaft.

[0026] The positioning component can lock the position of the conduit 17 to prevent slippage during the flow guidance process. To release the positioning effect of the positioning component, hold the handle 6 at one end of the crossbar and turn the handle 6 to rotate the pressure rod 12 along the side plate 13. At the same time, the rotating seat 11 connected to the top of the pressure rod 12 moves backward, which in turn moves the positioning rod 18 backward. The part of the pressure rod 12 between the side plate 13 and the rotating seat 11 is telescopic. After the positioning rod 18 is released from the clamping of the conduit 17, the conduit 17 can be moved. Since the end plate at the top of the flow guide seat 27 is connected to the rotating seat 11 by the first spring 10, the first spring 10 is compressed. When it is necessary to re-lock the position of the conduit 17, release the handle 6, and the first spring 10 in the positioning component will drive the other components to reset.

[0027] like Figure 1 and Figure 4 As shown, the bottom end of the flow guide seat 27 is connected to the collection pipe 5, which is connected to all the flow guide holes 4. The bottom end of the collection pipe 5 is connected to the one-way valve 7, which is directed from the collection pipe 5 to the waste liquid hose 22. The bottom end of the one-way valve 7 is connected to the waste liquid tank 8 through the waste liquid hose 22. The waste liquid tank 8 is placed on the base plate 3, and a drain valve 9 is connected to one side of the waste liquid tank 8.

[0028] like Figure 1 and Figure 3 As shown, the bottom end of the waste liquid hose 22 is fixed to the top of the waste liquid tank 8 by a clamping assembly. The clamping assembly includes a fixed base 26 provided on one side of the waste liquid tank 8. A pair of connecting plates 24 are rotatably clamped on the fixed base 26. One end of the two connecting plates 24 is connected by a second spring 23. The free ends of the two connecting plates 24 are slidably clamped with sliding rods 25. The free ends of the sliding rods 25 are hinged with fixing clips 20. A pair of directional blocks 21 are provided at the top of the waste liquid tank 8. The two fixing clips 20 are slidably clamped on the two directional blocks 21 respectively. The two fixing clips 20 are respectively clamped at the bottom end of the waste liquid hose 22.

[0029] like Figure 1 and Figure 4 As shown, the adjustment assembly includes a hydraulic rod 28 disposed between the flow guide seat 27 and the base plate 3. The two ends of the hydraulic rod 28 are respectively hinged to the flow guide seat 27 and the base plate 3. A pair of parallel clamping plates 30 are rotatably connected to the bottom end of the flow guide seat 27. A pair of plate sleeves 29 are rotatably connected to the base plate 3. The two clamping plates 30 are slidably clamped in the two plate sleeves 29 respectively.

[0030] The clamping assembly connects the waste liquid hose to the waste liquid tank. When the clamping assembly needs to release the waste liquid hose, the two connecting plates are rotated along the fixed base to compress the second spring at one end of the connecting plate. At this time, the slide rod locked at the free end of the connecting plate will drive the fixed clamp to slide along the directional block, causing the fixed clamp to release the waste liquid hose. The waste liquid hose can then be removed, and one end of the connecting plate is released. The two connecting plates will then reset under the elastic force of the second spring, causing the fixed clamp connected to the slide rod at one end of the connecting plate to re-clamp the waste liquid hose.

[0031] like Figure 1 As shown, the bottom of the base plate 3 is equipped with multiple sets of casters, and a connecting arm 2 is hinged to the base plate 3. A pull rod 1 is connected to one side of the top of the connecting arm 2. Medical staff can easily move the base plate 3 and the device as a whole with the help of the casters, the pull rod 1 and the connecting arm 2.
