Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a conversion connector assembly and a dialysate filter. Background Technology
[0002] Dialysis fluid filters are mainly used in the process of hemodialysis to filter the dialysate.
[0003] In the early days of hemodialysis, dialysis equipment and techniques were relatively simple, and the requirements for the purity of the dialysate were not as high as they are now. With the advancement of medical technology, people have gradually realized that impurities, bacteria, endotoxins, and other substances in the dialysate can pose many risks to patients, such as triggering inflammatory reactions and allergic reactions.
[0004] Traditional dialysis systems may not be effective at removing tiny particles and harmful substances from dialysate. Dialysis fluid filter technology emerged to address this need, driven by the need to improve the safety and effectiveness of dialysis treatment. High-precision dialysate filters utilize advanced membrane materials to trap impurities of varying sizes, finely filtering the dialysate to ensure patients receive cleaner, more treatment-compliant fluid.
[0005] Currently, general-purpose dialysate filters are typically made compatible with dedicated dialysis machines by adding adapter components. However, existing adapter components are expensive to manufacture, have many parts, making assembly difficult. Furthermore, they have fixed size requirements for dialysate filters and cannot be used interchangeably with other brands, resulting in certain limitations in their use. Utility Model Content
[0006] Therefore, the purpose of this utility model is to provide a conversion connector assembly and a dialysate filter, which aims to solve the compatibility problem of some special-purpose models.
[0007] This utility model provides a conversion connector assembly disposed on both sides of a dialysate filter. The dialysate filter includes a main tube, side covers disposed on both axial sides of the main tube, an upper conduit extending outward circumferentially along both sides of the main tube, and a side conduit extending outward along the side cover away from the main tube. The conversion connector assembly includes an upper connector sleeved on the upper conduit, a side connector sleeved on the side conduit, a connecting tube for connecting the upper connector and the side connector, and a locking pin group for securing the upper connector and the side connector to the upper conduit and the side conduit, respectively.
[0008] The locking pin assembly includes a first locking pin that is embedded in the upper connector and engages with the upper conduit, and a second locking pin that is embedded in the side connector and engages with the side conduit.
[0009] As described above, for the assembly of the dialysate filter conversion connector assembly, the operator can sequentially install the connector on the upper guide tube, install the side connector on the side guide tube, and install a connecting tube between the first and second connecting tubes. Then, the first and second locking pins can be inserted sequentially into the first and second locking pin slots, respectively, so that the first locking pin passes through the first connecting pipe end and locks onto the upper guide tube, locking the upper connector on the upper guide tube vertically. The second locking pin passes through the second connecting pipe end and locks onto the side guide tube, locking the side connector on the side guide tube horizontally. Finally, the assembly operation of the dialysate filter conversion connector assembly is completed. The installation method is simple and quick, convenient for operators to install, and solves the compatibility problem of some existing special models.
[0010] In addition, the adapter assembly proposed according to the embodiments of this utility model may also have the following additional technical features:
[0011] Furthermore, the upper connector includes a first connecting end sleeved on the upper conduit, an adapter disposed at the top of the first connecting end, and a first connecting pipe disposed at the bottom of the adapter and on the side away from the first connecting end for connecting the connecting pipe.
[0012] Furthermore, the bottom of the first connecting pipe end is provided with a series of through grooves that respectively accommodate the first locking pin and the upper conduit.
[0013] Furthermore, the through-slot assembly includes a first conduit slot formed at the bottom end of the first connecting pipe end for accommodating at least a portion of the upper conduit, and a first locking pin slot formed on one side of the bottom of the first connecting pipe end for accommodating the first locking pin.
[0014] Furthermore, the side connector includes a second connecting pipe end sleeved on the side conduit, and a second connecting pipe extending along the second connecting pipe end toward the first connecting pipe, the second connecting pipe being connected to the connecting pipe and the first connecting pipe respectively.

[0029] Please see Figures 1 to 5The diagram shows the adapter assembly in this embodiment of the present invention, which is disposed on both sides of the dialysate filter 1. The dialysate filter 1 includes a main tube 11, side covers 13 disposed on both axial sides of the main tube 11, an upper conduit 12 extending outward circumferentially along both sides of the main tube 11, and a side conduit 14 extending outward along the side of the side cover 13 away from the main tube 11. The adapter assembly 2 includes an upper connector 21 sleeved on the upper conduit 12, a side connector 24 sleeved on the side conduit 14, a connecting tube 23 for connecting the upper connector 21 and the side connector 24, and a locking pin group for securing the upper connector 21 and the side connector 24 to the upper conduit 12 and the side conduit 14, respectively. The locking pin group includes a first locking pin 22 embedded in the upper connector 21 and engaging with the upper conduit 12, and a second locking pin 25 embedded in the side connector 24 and engaging with the side conduit 14.
[0030] Furthermore, the upper connector 21 includes a first connecting pipe end 211 sleeved on the upper conduit 12 and an adapter 214 disposed on the top of the first connecting pipe end 211. The adapter 214 has two connecting pipe grooves, which can be used to connect to a dedicated machine when converting a general-purpose dialysate filter into a dedicated dialysate filter. Further explanation is needed, in this application, the dedicated machine is a dialysis machine, which typically requires a dedicated dialysate filter. This is understandable to those skilled in the art and will not be elaborated upon here. A first connecting pipe 215 is disposed at the bottom of the adapter 214 and on the side away from the first connecting pipe end 211 for connecting the connecting pipe 23. The bottom of the first connecting pipe end 211 has a series of through grooves that respectively accommodate the first locking pin 22 and the upper conduit 12. The first conduit groove 212, which is located at the bottom of the first connecting end 211 and is used to accommodate at least part of the upper conduit 12, and the first locking groove 213, which is located on one side of the bottom of the first connecting end 211 and is used to accommodate the first locking pin 22, are included. The side connector 24 includes a second connecting end 241 sleeved on the side conduit 14 and a second connecting pipe 244 extending from the second connecting end 241 toward the first connecting pipe 215. The second connecting pipe 244 is connected to the connecting pipe 23 and the first connecting pipe 215 respectively. The second connecting end 241 is provided with a second through groove group on the side of the side conduit 14 to accommodate the second locking pin 25 and the side conduit 14 respectively. The second through groove group includes a second conduit groove 242 for accommodating at least part of the side conduit 14 and a second locking groove 243 for accommodating the second locking pin 25 is provided on the side of the second connecting end 242.
[0031] In practical implementation, operators can adjust the dialysate filter 1 according to its usage needs. For example, when converting a general-purpose dialysate filter to a special-purpose dialysate filter, conversion connector assemblies 2 can be added to both sides of the dialysate filter 1. Specifically, a connector 21 is fitted onto the upper conduit 12, and a side connector 24 is fitted onto the side conduit 14. It is important to ensure that the first connecting pipe 215 and the second connecting pipe 244 are in a relative position when assembling the connector 21 and the side connector 24. Then, a connecting pipe 23 is installed between the first connecting pipe 215 and the second connecting pipe 244. In some optional embodiments, the connection between the connecting pipe 23 and the first connecting pipe 215 and the second connecting pipe 244 can be either sleeved or screwed. Additionally, a first sealing ring can be embedded near the first conduit groove 212 at the first connecting pipe end 211 for fitting onto the upper conduit 12, ensuring that the first connecting pipe end 211 and the upper conduit 14 are properly connected. Similarly, to ensure the airtightness of the connection between the two, a second sealing ring can also be provided at the second pipe end 241 near the second conduit groove 242 for fitting onto the side conduit 14. The inner diameters of both the first and second sealing rings are smaller than the outer diameters of the ends of the upper conduit 12 and the side conduit 14, so that during the fitting process, the first and second sealing rings can deform and adjust according to the outer diameter, effectively fitting the deformation of the ends of the upper conduit 12 and the side conduit 14 to ensure a seal. Then, the operator can sequentially insert the first locking pin 22 and the second locking pin 25 into the first locking pin groove 213 and the second locking pin groove 243 respectively, so that the first locking pin 22 passes through the first pipe end 211 and is locked onto the upper conduit 12, locking the upper connector 21 on the upper conduit 12 vertically, and the second locking pin 25 passes through the second pipe end 241 and is locked onto the side conduit 14, locking the side connector 24 on the side conduit 14 horizontally. It should be noted that, if... Figure 1 As shown in the exploded view, the upper conduit 12 and the side conduit 14 are respectively provided with snap-fit parts that correspond to and are adapted to the first snap-fit pin 22 and the second snap-fit pin 25 to ensure stable connection and finally complete the assembly operation of the conversion connector assembly 2 on both sides of the dialysate filter 1. The installation method is simple and quick, which is convenient for operators to install. Finally, the operator can use the dialysate filter 1 equipped with the conversion connector assembly 2 by inserting the conduit through the conversion interface 214.
[0032] In summary, for the assembly of the adapter assembly 2 on the dialysate filter 1, the operator can sequentially install the upper connector 21 on the upper conduit 12, install the side connector 24 on the side conduit 14, and install the connecting pipe 23 between the first connecting pipe 215 and the second connecting pipe 244. Then, the first locking pin 22 and the second locking pin 25 can be inserted sequentially into the first locking pin groove 213 and the second locking pin groove 243, respectively, so that the first locking pin 22 passes through the first connecting pipe end 211 and is locked on the upper conduit 12, locking the upper connector 21 on the upper conduit 12 vertically. The second locking pin 25 passes through the second connecting pipe end 241 and is locked on the side conduit 14, locking the side connector 24 on the side conduit 14 horizontally. Finally, the assembly operation of the adapter assembly 2 on both sides of the dialysate filter 1 is completed. The installation method is simple and quick, convenient for operators to install, and solves the compatibility problem of some existing special models.
