Solution preparation device for hemodialysis

Abstract

The invention discloses a solution preparation device for hemodialysis. The device comprises a cylinder and an upper cover, wherein a motor is mounted on the upper cover, a rotating shaft of the motorpenetrates the upper cover and extends into the cylinder, a connecting shaft is fixed at the lower end of the rotating shaft, three stirring blades are fixed around the rotating shaft, and a spiral blade is formed on the connecting shaft from top to bottom; the rotating direction of the spiral blade is the same as that of the rotating shaft; a plurality of spiral dents with the same rotating direction are arranged on the inner side wall of the cylinder, and the rotating direction of the spiral dents is opposite to that of the rotating shaft. According to the solution preparation device for hemodialysis, circulating agitation of a dialysis concentrated solution is realized, agitation efficiency and uniformity are improved, and the stirring area of the stirring blades is maximized; the heated dialysis concentrated solution rises along the spiral dents, vortex is produced, and precipitation and a too cold dialysate are avoided.

Description

technical field [0001] The present invention relates to medical equipment, more specifically, to a liquid dispensing device for hemodialysis. Background technique [0002] In recent years, hemodialysis technology has been widely used and developed in the medical field. The range of hemodialysis treatment is becoming wider and wider. Many medical units have established hemodialysis centers with increasing workload. The work of configuring the hemodialysis concentrate has become more and more a prominent problem in the daily dialysis treatment work. In the past, due to the small workload, when preparing the concentrated hemodialysis solution, the concentrated hemodialysis dry powder was usually poured into the liquid mixing tank, a certain amount of dialysis water was added, and then manually stirred with a stick. There were many problems in this operation: [0003] 1. The amount of concentrated hemodialysis solution prepared each time is relatively small, generally only a fe...

AI Technical Summary

Problems solved by technology

[0003] 1. The amount of concentrated hemodialysis solution prepared each time is relatively small, generally only a few liters to dozens of liters can be prepared; 2. The dialysis powder needs to be fully stirred to dissolve, and the manual stirring effect is poor, time-consuming and laborious, and dialysis powder in cold areas It is not easy to dissolve; 3. When stirring manually, the opening of the dosing barrel is open, which is easy to cause pollution of the hemodialysis concentrate, and the hemodialysis concentrate is also easily oxidized by oxygen in the air; Scoop it out one by one, and then pack it into small buckets for dialysis after leaking; 5. The temperature of the prepared hemodialysis concentrate is too low, which affects the use

6. Precipitation is easy to occur when the prepared hemodialysis concentrate is placed, which affects the use
