Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a quantitative mixing device for configuring raw materials of peritoneal dialysis fluid. Background Art

[0002] Dialysate is a special solution used to cleanse the blood during dialysis treatment. Dialysis is a treatment that is often used for people with kidney failure to remove metabolic waste, electrolytes and excess fluid from the blood.

[0003] Dialysis fluid is mostly a mixture of electrolytes, glucose buffer and water. During preparation, personnel need to mix the above raw materials in corresponding proportions. Specifically, personnel need to weigh the above raw materials and add them into a stirring device, which stirs and mixes the raw materials. In existing small-sized peritoneal dialysis fluid raw material mixing devices, due to the relatively simple structure of the device, personnel often weigh the raw materials before adding them. However, this requires preparing another container for storage and is prone to omission. The weighing device of the device is often fixed to the shell. However, in order to ensure the sterility of the dialysate, the weighing device needs to be removed for disinfection after being used for a period of time. The one-piece fixation is easy to cause contamination to the raw materials added subsequently due to the inability to replace. Therefore, the existing peritoneal dialysis fluid raw material configuration quantitative mixing device still has certain shortcomings.

[0004] In summary, it is necessary to invent a quantitative mixing device for configuring peritoneal dialysis fluid raw materials. Utility Model Content

The drain valve 440 is converted from a horizontal state to a vertical state, so that the raw materials can be discharged into the liquid preparation tank 100 through the liquid outlet 430;

[0028] In the above - mentioned manner, personnel can add other raw materials into the liquid - preparation tank 100. Then, the personnel can externally connect a power source to start the stirring motor 200 by energizing it, so that the stirring motor 200 can drive the stirring rod 210 to rotate, and the stirring rod 210 can mix the raw materials to prepare dialysis fluid. Then, the personnel can open the valve at the bottom of the drain port 310, and the valve can be an electromagnetic valve or a manual valve. The manual valve can be opened from the cabinet door at the front end of the liquid - preparation tank 100. After opening, the drain port 310 will transport the dialysis fluid towards the filter layer 320. The provided filter layer 320 can roughly filter the solid particles in the dialysis fluid, and then the dialysis fluid can be discharged through the drain pipe. The discharged dialysis fluid can be finely filtered through a filter membrane and then disinfected before being used;

[0029] After the device has been used for a period of time, the spline shaft 442 can be removed first, and then the raw - material metering barrel 420 can be directly removed from the liquid inlet for cleaning. Then, by opening the cabinet door, the liquid - separating plate 300 can be pulled out from the liquid - preparation tank 100 for cleaning. At the same time, the filter layer 320 can also be moved upward and removed for cleaning.
