Description

Technical Field

[0001] This utility model relates to the medical field, and in particular to a quantitative dialysis fluid filling device. Background Technology

[0002] Dialysis fluid is a special solution used to replace waste and excess fluid that cannot be properly excreted from the body of patients with renal insufficiency. In the medical field, as a key consumable in hemodialysis treatment, the accuracy and safety of its filling process are directly related to the treatment effect and resource utilization efficiency.

[0003] After filling, existing dialysis fluid filling devices typically retract the filling tube by moving it upwards from the filling container. Since dialysis fluid remains inside the filling tube, leakage is very likely to occur under the influence of gravity or when the equipment is moved, which can easily lead to the waste of this valuable medical resource and increase medical costs.

[0004] Therefore, it is necessary to design a quantitative dialysate filling device that can seal the filling tube when it is retracted to prevent dialysate leakage and waste. Utility Model Content

[0005] To overcome the shortcomings of existing dialysis fluid filling devices, which leave residual dialysis fluid in the filling tube after filling and are prone to leakage under gravity or when the equipment is moved, thus wasting this valuable medical resource and increasing medical costs, this invention provides a quantitative dialysis fluid filling device that can seal the filling tube when it is retracted to prevent leakage and waste.

[0006] Technical Solution: A quantitative dialysis fluid filling device includes a base, a storage tank, an outlet pipe, a metering pump, a metering turbine, a motor, a lead screw, a sliding plate, a filling tube, and a sealing assembly. The storage tank is connected to the upper left side of the base, and the metering pump is connected to the upper right side of the storage tank. The outlet pipe is connected to the metering pump, and the metering turbine is rotatably connected to the upper left side of the outlet pipe. The motor is connected to the lower middle part of the base, and the motor and the processor are electrically connected through a control module. The lead screw is connected to the output shaft of the motor and is rotatably connected to the base. The sliding plate is threaded onto the lead screw and is slidably connected to the base. The filling tube is slidably connected to the outlet pipe, and the filling tube is equipped with a sealing assembly that can seal the filling tube when it is retracted.

[0007] Furthermore, it is particularly preferred that the liquid storage tank has a screw-on knob on the upper part.

[0008] Furthermore, it is particularly preferred that the lower part of the filling tube has a conical structure.

[0009] Furthermore, it is particularly preferred that the sealing assembly includes a first guide frame, a support frame, a pressure frame, a first roller, a first telescopic spring, a sealing frame, and a second telescopic spring. The first guide frame is connected to the upper part of the base, the support frame is connected to the lower part of the filling tube, the pressure frame is slidably connected to the left side of the support frame, the pressure frame is slidably connected to the filling tube, the first roller is rotatably connected to the left side of the pressure frame, the first roller contacts the first guide frame, the first telescopic spring is connected between the pressure frame and the filling tube, the sealing frame is slidably connected to the lower part of the support frame, the sealing frame contacts the pressure frame, and the second telescopic spring is connected between the sealing frame and the support frame.

[0010] Furthermore, it is particularly preferred that the portions of the extrusion frame and the sealing frame that are close to each other are both wedge-shaped structures.

[0011] Furthermore, it is particularly preferred that the slide also includes a second guide frame, a guide rod, a sliding frame, a second roller, a third telescopic spring, and a collection dish. The second guide frame is connected to the left side of the slide plate and is slidably connected to the base. The guide rod is connected to the upper right side of the base and is slidably connected to the guide rod. The second roller is rotatably connected to the rear left side of the sliding frame. The third telescopic spring is connected between the sliding frame and the guide rod. The collection dish is placed on the lower right side of the sliding frame.

[0012] Beneficial effects: 1. This utility model uses a sliding plate that moves upward under the action of the thread, the first roller rotates and moves upward along the first guide frame, driving the extrusion frame to move to the right. The extrusion frame moves to the right to extrude the sealing frame, driving the sealing frame to move downward to close, thus sealing the lower part of the canning tube. This achieves the effect of sealing the canning tube when it is retracted, avoiding the leakage of dialysis fluid and causing waste.

[0013] 2. This utility model moves the second guide frame upward, causing the second roller to move backward and rotate. The third telescopic spring returns to its original position, driving the sliding frame to move backward, so that the collection dish is located below the filling tube. This allows the residual dialysis fluid at the bottom of the filling tube to drip onto the collection dish, achieving the effect of timely collection of the residual dialysis fluid at the bottom of the filling tube, avoiding the waste of resources caused by dialysis fluid dripping into the surrounding environment and causing environmental pollution.

[0020] A quantitative dialysate filling device, such as Figure 1 and Figure 2 As shown, the system includes a base 1, a storage tank 2, an outlet pipe 3, a metering pump 4, a metering turbine 5, a motor 6, a lead screw 7, a sliding plate 8, a filling pipe 9, and a sealing assembly. The storage tank 2 is connected to the upper left side of the base 1. The storage tank 2 has a threaded knob on its upper part for easy gripping. The metering pump 4 is connected to the upper right side of the storage tank 2. The outlet pipe 3 is connected to the metering pump 4. The metering turbine 5 is rotatably connected to the upper left side of the outlet pipe 3. The motor 6 is connected to the lower middle part of the base 1. The motor 6 and the processor are electrically connected through a control module. The lead screw 7 is connected to the output shaft of the motor 6. The lead screw 7 is rotatably connected to the base 1. The sliding plate 8 is threadedly connected to the lead screw 7. The sliding plate 8 is slidably connected to the base 1. The filling pipe 9 is slidably connected to the outlet pipe 3. The lower part of the filling pipe 9 has a conical structure for easy material feeding. The filling pipe 9 is equipped with a sealing assembly.

[0021] like Figure 1 and Figure 3As shown, the sealing assembly includes a first guide frame 10, a support frame 11, a pressure frame, a first roller 13, a first telescopic spring 14, a sealing frame 15, and a second telescopic spring 16. The first guide frame 10 is connected to the upper part of the base 1, and the support frame 11 is connected to the lower part of the filling tube 9. The left side of the support frame 11 is slidably connected to the extrusion frame 12, which is slidably connected to the filling tube 9. The left side of the extrusion frame 12 is rotatably connected to the first roller 13, which is in contact with the first guide frame 10. The first telescopic spring 14 is connected between the extrusion frame 12 and the filling tube 9. The sealing frame 15 is slidably connected to the lower part of the support frame 11. The parts of the extrusion frame 12 and the sealing frame 15 that are close to each other are wedge-shaped structures. The sealing frame 15 is in contact with the extrusion frame 12, and the second telescopic spring 16 is connected between the sealing frame 15 and the support frame 11.

[0022] like Figure 1 and Figure 4 As shown, it also includes a second guide frame 17, a guide rod 18, a sliding frame 19, a second roller 20, a third telescopic spring 21, and a collection dish 22. The left side of the slide plate 8 is connected to the second guide frame 17, which is slidably connected to the base 1. The upper right side of the base 1 is connected to the guide rod 18, and the sliding frame 19 is slidably connected to the guide rod 18. The left rear of the sliding frame 19 is rotatably connected to the second roller 20. The third telescopic spring 21 is connected between the sliding frame 19 and the guide rod 18. The collection dish 22 is placed on the lower right side of the sliding frame 19.

[0023] At this time, the first telescopic spring 14 and the second telescopic spring 16 are in the contracted state. When using this device, first place the base 1 in the dialysis fluid filling area, and then place the filling barrel on the base 1 so that the filling barrel is below the filling tube 9. The processor starts the motor 6 through the control module, which drives the lead screw 7 to rotate, causing the slide plate 8 to move downward under the action of the thread, thus moving the filling tube 9 downward. At the same time as the slide plate 8 moves downward, it will also drive the second guide frame 17 to move downward. The downward movement of the second guide frame 17 squeezes the second roller 20 to move forward and rotate, thus driving the sliding frame 19 to move forward on the guide rod 18. The third telescopic spring 21 is compressed and contracts, causing the collection dish 22 to no longer be located below the filling tube 9. Simultaneously, the filling tube 9 extends into the filling container. As the filling tube 9 moves downward, it drives the squeezing frame 12 downward, causing the first roller 13 to rotate and move along the first guide frame 10. The first telescopic spring 14 gradually returns to its original state, causing the squeezing frame 12 to move to the left. The second telescopic spring 16 returns to its original state, causing the sealing frame 15 to move upward on the support frame 11 and open. Then, the metering pump 4 is started, allowing the dialysate in the storage tank 2 to be discharged from the filling tube 9 through the outlet pipe 3. As the dialysate flows... The metering turbine 5 rotates, measuring the flow rate of the dialysate. When the dialysate tank reaches a certain volume, the metering pump 4 shuts off. Simultaneously, the motor 6 drives the lead screw 7 to rotate, causing the slide plate 8 to move upward under the action of the thread. This causes the first roller 13 to rotate and move upward along the first guide frame 10. The first guide frame 10 compresses the first roller 13, causing the compression frame 12 to move to the right. The first telescopic spring 14 is compressed and contracts, compressing the sealing frame 15 through the rightward movement of the compression frame 12. This causes the sealing frame 15 to move downward and close. The second telescopic spring 16 is then compressed. The compression and contraction seals the lower part of the canister tube 9, preventing leakage and waste of dialysate when the canister tube 9 is retracted. As the slide plate 8 moves downward, it drives the second guide frame 17 to move upward, causing the second roller 20 to move backward and rotate. The third telescopic spring 21 returns to its original position, driving the sliding frame 19 to move backward, so that the collection dish 22 is located below the canister tube 9. This allows the residual dialysate at the lower part of the canister tube 9 to drip onto the collection dish 22, thus enabling timely collection of the residual dialysate at the lower part of the canister tube 9 and preventing the dialysate from dripping into the surrounding environment and causing environmental pollution and resource waste.
