Description

Technical Field

[0001] This utility model relates to the field of dialyzer technology, specifically a dopamine dialyzer. Background Technology

[0002] Hemodialysis, a common extracorporeal circulation treatment for acute or chronic renal failure, works by removing toxic and harmful substances from the blood through a dialyzer membrane to treat the disease and maintain life. However, many patients lack knowledge about hemodialysis and its safety, are not psychologically prepared, and experience significant changes in their daily lives, leading to anxiety and fear. Dialysis is typically performed 2-3 times a week, with each session lasting up to 4 hours. As dialysis time increases, various complications may gradually appear. The psychological balance of dialysis patients is disrupted, leading to a lack of confidence in the disease and further exacerbating their pessimism and despair. They also suffer both physical and psychological pain. To effectively remove toxins and excess water from the body, a dialyzer is needed. However, existing dialyzers still have the following shortcomings:

[0003] When using existing dialyzers, most dialyzers do not have the function of releasing dopamine, which can cause patients to have excessive psychological burden during long-term dialysis. At the same time, they are less likely to actively seek treatment, which ultimately affects their quality of life and overall lifespan, resulting in a decrease in the practicality and efficiency of dialyzers. Utility Model Content

[0004] The purpose of this invention is to provide a dopamine dialyzer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dopamine dialyzer, comprising a dialysate body, a rubber sealing ring, and mounting rings. The dialysate body has a dialysate outlet on its outer left side and a dialysate inlet on its outer right side. The dialysate body has an external thread on its outer left end and a first sealing cap connected to it. The first sealing cap has a blood inlet at its outer center and an internal thread inside. A first mounting groove is formed on the left side of the first sealing cap, and a rubber sealing ring is connected inside the first mounting groove. The dialysate body has second mounting grooves at both ends, and a second sealing cap is connected to the outer right end of the dialysate body. A blood outlet is formed at the outer center of the second sealing cap. Mounting rings are formed on both sides of the dialysate body, and mounting slots are formed inside each mounting ring. Mounting blocks are connected inside each mounting slot, and limit rings are formed inside each mounting block. A dialysis membrane body is disposed inside each limit ring.

[0006] Furthermore, the external dimensions of the dialysis tube body are adapted to the internal dimensions of the first sealing cap, and the first sealing cap is rotatably connected to the dialysis tube body via an external thread.

[0007] Furthermore, the internal dimensions of the first mounting groove are adapted to the external dimensions of the rubber sealing ring, and the rubber sealing ring is connected to the first sealing cover through the first mounting groove.

[0008] Furthermore, there are two rubber sealing rings, and the two rubber sealing rings are symmetrically arranged at both ends of the outside of the dialysis tube body with respect to the central axis of the front side of the dialysis tube body.

[0009] Furthermore, the internal dimensions of the second mounting groove are adapted to the external dimensions of the rubber sealing ring, and the rubber sealing ring is embeddedly connected to the dialysis tube body through the second mounting groove.

[0010] Furthermore, the external dimensions of the mounting ring are adapted to the internal dimensions of the dialysis tube body, and the mounting ring is fixedly connected to the dialysis tube body by an adhesive.

[0011] Furthermore, the internal dimensions of the mounting slot are adapted to the external dimensions of the mounting block, and the mounting block is slidably connected to the mounting ring through the mounting slot.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figure 1 To the end Figure 3As shown, a dopamine dialyzer includes a dialysate body 1, a rubber sealing ring 9, and a mounting ring 13. A dialysate outlet 2 is located on the left side of the dialysate body 1, and a dialysate inlet 3 is located on the right side. An external thread 4 is located on the left end of the dialysate body 1, and a first sealing cap 5 is connected to the left end of the dialysate body 1. A blood inlet 6 is located at the middle of the outer side of the first sealing cap 5, and an internal thread 7 is located inside the first sealing cap 5. A first mounting groove 8 is formed on the left side of the inside of the first sealing cap 5, and a rubber sealing ring 9 is connected inside the first mounting groove 8. The dialysis tubing body 1 has two rubber sealing rings 9. Two mounting grooves 10 are provided at both ends inside the dialysis tubing body 1. A second sealing cap 11 is connected to the right end of the dialysis tubing body 1, and a blood outlet 12 is provided at the middle of the outer side of the second sealing cap 11. The external dimensions of the dialysis tubing body 1 are adapted to the internal dimensions of the first sealing cap 5, and the first sealing cap 5 is rotatably connected to the dialysis tubing body 1 via an external thread 4. The internal dimensions of the first mounting groove 8 are adapted to the external dimensions of the rubber sealing ring 9, and the rubber sealing ring 9 is connected to the first sealing cap 5 via the first mounting groove 8. Two rubber sealing rings 9 are provided. A rubber sealing ring 9 is symmetrically arranged at both ends of the dialysis tube body 1 along the central axis of the front side. The internal dimensions of the second mounting groove 10 are adapted to the external dimensions of the rubber sealing ring 9, and the rubber sealing ring 9 is embedded in the dialysis tube body 1 through the second mounting groove 10. The first sealing cover 5 is rotated and installed on the left end of the dialysis tube body 1 by the external thread 4 on the left side of the dialysis tube body 1 and the internal thread 7 on the inside of the first sealing cover 5. Similarly, the second sealing cover 11 is installed on the right end of the dialysis tube body 1, and the blood inlet 6 in the middle of the first sealing cover 5 is used for this purpose. Blood is fed into the dialysis tube body 1, and simultaneously discharged through the blood outlet 12 located in the middle of the second sealing cap 11. The internal dimensions of the first mounting groove 8 inside the first sealing cap 5 are adapted to the external dimensions of the rubber sealing ring 9. At the same time, the internal dimensions of the second mounting grooves 10 at both ends of the dialysis tube body 1 are also adapted to the external dimensions of the rubber sealing ring 9. Thus, when the first sealing cap 5 and the second sealing cap 11 are rotated and installed with the dialysis tube body 1, the rubber sealing ring 9 improves the overall sealing performance after installation, thereby enhancing the overall practicality and efficiency of the dialyzer.

[0022] like Figures 1 to 3As shown, mounting rings 13 are provided on both sides inside the dialysis tube body 1, and mounting grooves 14 are provided inside the mounting rings 13. Mounting blocks 15 are connected inside the mounting grooves 14, and limiting rings 16 are provided inside the mounting blocks 15. Dialysis membrane bodies 17 are provided inside the limiting rings 16. The external dimensions of the mounting rings 13 are adapted to the internal dimensions of the dialysis tube body 1, and the mounting rings 13 are fixedly connected to the dialysis tube body 1 by adhesive. The internal dimensions of the mounting grooves 14 are adapted to the external dimensions of the mounting blocks 15, and the mounting blocks 15 are slidably connected to the mounting rings 13 through the mounting grooves 14. The number of mounting blocks 15 is set as follows. There are four mounting blocks 15, which are equidistantly distributed at the four corners of the outer side of the limiting ring 16. The mounting ring 13 is fixedly installed on both sides of the inside of the dialysis tube body 1 by adhesive. The internal dimensions of the mounting slot 14 opened inside the mounting ring 13 are adapted to the external dimensions of the mounting blocks 15 added to the outside of the limiting ring 16. Thus, the limiting ring 16 is limited and installed into the inside of the mounting ring 13 by the mounting slot 14 and the mounting blocks 15, thereby completing the limiting installation of the dialysis membrane body 17 inside the limiting ring 16. This makes the dialysis membrane body 17 easy to install and disassemble, improves the efficiency of subsequent medical waste recycling, and increases the convenience of using the dialyzer.

[0023] In summary, during use, the dopamine dialyzer first introduces dopamine injection solution into the dialysis tubing body 1 through the blood inlet 6. Compressed air then blows the solution throughout the dialyzer, ensuring the dialysis membrane body 17 is fully wetted. Through adsorption, dopamine molecules are adsorbed into the pores of the dialysis membrane. Low-temperature negative pressure drying further prevents molecular degradation, ultimately achieving physical fixation of the dopamine molecules. This allows the dopamine injection solution to effectively and specifically maintain a positive psychological state in patients during hemodialysis, reducing their psychological burden and encouraging active treatment, ultimately improving their quality of life and extending their lifespan. The mounting rings 13 are fixed to both sides of the dialysis tubing body 1 using adhesive, and the mounting slots 14 cooperate with the mounting clips. Block 15 limits the installation of the limiting ring 16 into the installation ring 13, thereby completing the limiting installation of the dialysis membrane body 17 inside the limiting ring 16, making the dialysis membrane body 17 easy to install and remove. Then, the first sealing cover 5 is rotated and installed on the left end of the dialysis tube body 1 by using the external thread 4 on the left side of the dialysis tube body 1 and the internal thread 7 on the inside of the first sealing cover 5. Similarly, the second sealing cover 11 is installed on the right end of the dialysis tube body 1, and blood is sent into the dialysis tube body 1 through the blood inlet 6 in the middle of the first sealing cover 5. At the same time, blood is sent out through the blood outlet 12 in the middle of the second sealing cover 11. The rubber sealing ring 9 improves the overall sealing performance after installation, improving the overall practicality and efficiency of the dialyzer.
