Description

Technical Field

[0001] This utility model relates to a dialysate filter connection platform and belongs to the field of product packaging technology. Background Technology

[0002] Hemodialysis (HD) and hemofiltration (HF) are the primary treatment options for end-stage renal failure patients with uremia and acute or chronic renal failure. Both hemodialysis and hemofiltration involve a blood pump introducing blood into the blood circuit side of a dialysate filter while simultaneously introducing dialysate into the dialysate side. Small and medium-sized molecules in the dialysate and blood exchange substances through a semi-permeable membrane within the dialysate filter, relying on their concentration gradient. Because dialysate filters have numerous interfaces, clinical use requires connecting each interface individually to the hemodialysis machine's solution preparation system, making the process cumbersome.

[0003] Currently, although quick-connect brackets are used to reduce the connection time between the dialysate filter and the various tubing, the large number of connecting parts and the complicated procedures require the use of multiple connectors. Therefore, in clinical use, there are still problems such as cumbersome replacement, difficult installation and disassembly, and complicated operation steps. In addition, the reliability and compatibility of the dialysate filter connection with the various tubing of the dialysis machine are poor. Utility Model Content

[0004] This utility model provides a dialysate filter connection platform, which aims to solve the technical problems of difficult installation and disassembly and poor compatibility of dialysate filters when connected to dialysis machine pipelines.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A dialysate filter connection platform includes a mounting base with two fixed interfaces symmetrically arranged at its left and right ends. The dialysate filter is installed between the two fixed interfaces. A slot is provided on the side of the fixed interface adjacent to the dialysate filter to guide the trapezoidal groove of the dialysate filter end cap. A sliding interface is embedded on the side of the fixed interface away from the dialysate filter. The sliding interface is connected to the fixed interface by a limiting steel column on its periphery, and a pressure spring is fitted on the limiting steel column to allow the sliding interface to move under the action of the pressure spring. The sliding interface has an end cap interface located in the slot and facing the end cap of the dialysate filter. The end cap interface connects to the end cap of the dialysate filter on one hand, and to an external dialysis machine pipeline on the other hand through a pipeline interface A provided on the sliding interface. Two symmetrical filter interfaces are provided on the bottom side of the mounting base, and the filter nozzle of the dialysate filter is also connected to the external dialysis machine pipeline through the filter interfaces.

[0007] Preferably, the outer periphery of the end cap interface is provided with a circular groove, and one side of the circular groove is provided with a guide slope. The arrangement direction of the end cap interface and the guide slope is consistent with the direction of the slot.

[0008] Preferably, the guide slope is an inclined plane, the low point of which corresponds to the opening end of the slot, and the high point of which is flush with the end cap interface.

[0009] Preferably, a slider is slidably installed on one side of the fixed interface through a slider limiting port, and a sliding hole is provided at one end of the slider that extends into the sliding interface. The sliding hole is limited and connected to a guide post provided on the sliding interface.

[0010] Preferably, the fixed interface has two parallel platforms, namely a first platform and a second platform. The sliding interface has two parallel circular holes on both sides, namely circular hole A and circular hole B. The top end of the limiting steel column passes through circular hole A and is fixed in the first hexagonal hole on the first platform. The bottom end of the limiting steel column passes through circular hole B and is fixed in the second hexagonal hole on the second platform. The pressure spring is clamped between circular hole A and circular hole B of the sliding interface.

[0011] The beneficial effects of this utility model are as follows: Through the above design, this utility model can solve the technical problems of poor compatibility and difficulty in installation and disassembly of dialysate filters. Moreover, the connecting platform of this utility model has a simple structure and low manufacturing difficulty, which ensures low cost while increasing practicality. Attached Figure Description

[0019] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0020] like Figures 1 to 6 The dialysate filter connection platform shown includes a mounting base 6. Two fixed interfaces 9 are symmetrically arranged at the left and right ends of the mounting base 6. A dialysate filter 2 is installed between the two fixed interfaces 9. A slot 1 is provided on the side of the fixed interface 9 adjacent to the dialysate filter 2. The slot 1 guides the trapezoidal groove of the end cap filter nozzle of the dialysate filter 2, ensuring that the dialysate filter can be inserted into the fixed interface 9 with proper restraint. A sliding interface 10 is embedded on the side of the fixed interface 9 away from the dialysate filter 2. The sliding interface 10 and the fixed interface 9 are connected by limiting steel columns 3 arranged around the periphery for restraint. A pressure spring 5 is fitted on the steel column 3, which ensures that the sliding interface 10 can maintain relative displacement between the two components under the action of the pressure spring 5. The sliding interface 10 is provided with an end cap interface 17, which is located in the slot 1 and faces the end cap filter of the dialysate filter 2. The end cap interface 17 is connected to the end cap filter of the dialysate filter 2 on one hand, and is connected to the external dialysis machine pipeline through the pipeline interface A22 provided on the sliding interface 10 on the other hand. Two filter interfaces 7 are symmetrically provided on the bottom side of the mounting base 6. The filter 4 of the dialysate filter 2 is also connected to the external dialysis machine pipeline through the filter interfaces 7.

[0021] Furthermore, the outer periphery of the end cap interface 17 is provided with a circular groove, and one side of the circular groove is provided with a guide slope 18. The arrangement direction of the end cap interface 17 and the guide slope 18 is consistent with the direction of the slot 1. The guide slope 18 is an inclined surface, the low point of the inclined surface corresponds to the opening end of the slot 1, and the high point of the inclined surface is flush with the end cap interface 17.

[0022] Furthermore, a slider 8 is slidably installed on one side of the fixed interface 9 via a slider limiting port 14. The end of the slider 8 that extends into the sliding interface 10 is provided with a sliding hole, which is limited and connected to the guide post 19 provided on the sliding interface 10.

[0023] Furthermore, the fixed interface 9 has two parallel platforms, namely the first platform 12 and the second platform 13. The sliding interface 10 has two parallel circular holes on both sides, namely circular hole A15 and circular hole B16. The top end of the limiting steel column 3 passes through the circular hole A15 and is fixed in the first hexagonal hole 24 on the first platform 12. The bottom end of the limiting steel column 3 passes through the circular hole B16 and is fixed in the second hexagonal hole 11 on the second platform 13. The pressure spring 5 is clamped between the circular hole A15 and the circular hole B16 of the sliding interface 10.

[0024] like Figure 6 As shown, during use, the dialysate filter end cap nozzle is pushed into the fixed interface 9 along the slot 1. The guide slope 18 of the sliding interface 10 is pushed vertically upward by the end cap nozzle. When the dialysate filter 2 reaches the designated position, the end cap nozzle no longer contacts the guide slope 18, and the sliding interface 10 moves downward by the reset action of the pressure spring 5, ensuring that the end cap interface 17 is inserted into the end cap nozzle. Then, the slider 8 is moved to the slider limit port 14, where it cannot move up or down, completing the fluid connection; simultaneously, as Figure 1 , Figure 5 As shown, the filter tip 4 of the dialysate filter 2 is inserted directly into the filter port 7, and the sealing ring of the groove 20 is inserted into the filter tip 4 to complete the seal, forming a fluid connection.

[0025] Continue as Figure 6 As shown, after the dialysate filter 2 has been used, the disassembly process is as follows: push the slider 8 to the slider limit port 14 to the position where it can move up and down, lift the slider 8 to drive the sliding interface 10 to move upward, the end cap interface 17 retracts from the dialysate filter 2, the limit port retracts, and the dialysate filter 2 is pulled out to complete the disassembly.

[0026] This solution can be adjusted for different models to meet the installation requirements of different dialysis machine models.
