Description

Technical Field

[0001] This utility model relates to the field of hemodialysis machine technology, and in particular to a drain connector for a hemodialysis machine. Background Technology

[0002] Current hemodialysis machines discharge waste fluid into the drainage channel through their own drain pipes, but lack corresponding drain connectors. Over time, protein esters in the waste fluid will adhere to the pipe walls, causing blockages and hindering drainage. This can lead to decreased dialysis treatment quality or trigger alarms and interruptions, with waste fluid flowing back into the hemodialysis machine and causing contamination. Currently, the solution is to remove the pipes and clean the blockages, which is cumbersome, time-consuming, and labor-intensive. Utility Model Content

Detailed Implementation

[0019] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0020] Please see Figure 1-4This embodiment provides a technical solution: a drain connector for a hemodialysis machine, including a support base 1, a power switch 7 installed on the side of the support base 1, a filter tube 6 fixed on the top of the support base 1, the filter tube 6 being a transparent structure, a filter screen cylinder 10 installed inside the filter tube 6, a conduit 2 fixedly connected to one end of the filter screen cylinder 10, an installation pipe 8 fixedly connected to the other end of the filter screen cylinder 10, a cleaning unit 4 for cleaning the inside of the filter screen cylinder 10 installed on the installation pipe 8, a sewage discharge unit 3 fixedly connected to the installation pipe 8, a drain pipe 9 fixedly connected to the filter tube 6, the end of the conduit 2 being connected to the drain end of the hemodialysis machine, waste liquid entering the filter screen cylinder 10 on the filter tube 6 through the conduit 2, filtering the waste liquid through the filter screen cylinder 10, and then discharging the waste liquid through the drain pipe 9. The filter tube 6 being a transparent structure allows observation of the filtration status of the filter screen cylinder 10.

[0021] It also includes a one-way valve 5, which is mounted on the conduit 2 to prevent backflow of liquid in the conduit 2.

[0022] It also includes a transparent observation window 11, which is fixed to the side of the conduit 2. A pH test paper 12 is provided on the inside of the transparent observation window 11. The color change of the pH test paper 12 inside the transparent observation window 11 provides a direct warning of abnormal waste liquid, which is very practical.

[0023] The cleaning unit 4 includes a spiral blade 41 and a servo motor 43. The servo motor 43 is mounted on the end of the mounting tube 8, and the spiral blade 41 is fixed on the output shaft of the servo motor 43. The spiral blade 41 is disposed inside the filter cylinder 10. The servo motor 43 is electrically connected to the power switch 7. The cleaning unit 4 also includes a cleaning brush 42, which is disposed at the edge of the spiral blade 41 and contacts the inner wall of the filter cylinder 10. The sewage discharge unit 3 includes a sewage discharge valve 31 and a sewage discharge pipe 32, which is connected to and fixed in the mounting tube 8. On the mounting pipe 8, the drain valve 31 is mounted on the drain pipe 32. When the filter cylinder 10 needs to be cleaned, the drain valve 31 is opened. At this time, the drain pipe 32 is connected to the mounting pipe 8. Then, the output shaft of the servo motor 43 drives the spiral blade 41 to rotate. The cleaning brush 42 on the spiral blade 41 cleans the dirt on the filter cylinder 10. The cleaned dirt is transported to the mounting pipe 8 through the spiral blade 41. The dirt is finally discharged through the drain pipe 32. It is convenient to clean and avoids the trouble of disassembling the pipe for cleaning, saving time and effort.

[0024] The working principle of the drain connector for a hemodialysis machine provided by this utility model is as follows: the color change of the pH test paper 12 in the transparent observation window 11 provides a direct warning of abnormal waste liquid. The one-way valve 5 prevents backflow of liquid in the conduit 2. The end of the conduit 2 is connected to the drain end of the hemodialysis machine. The waste liquid enters the filter screen 10 on the filter tube 6 through the conduit 2 and is filtered by the filter screen 10. Then, the waste liquid is discharged through the drain pipe 9. The filter tube 6 is transparent, so the filtration status of the filter screen 10 can be observed. When the filter screen 10 needs to be cleaned, the drain valve 31 is opened. At this time, the drain pipe 32 is connected to the installation pipe 8. Then, the output shaft of the servo motor 43 drives the spiral blade 41 to rotate. The cleaning brush 42 on the spiral blade 41 cleans the dirt on the filter screen 10. The cleaned dirt is transported to the installation pipe 8 through the spiral blade 41 and finally discharged through the drain pipe 32.
