A liquid dispensing device for hemodialysis

Abstract

The invention discloses a liquid dispensing device for hemodialysis, which comprises a cylinder body and an upper cover, the upper cover is equipped with a motor, the rotating shaft of the motor penetrates the upper cover and extends into the cylinder body, and the lower end of the rotating shaft is fixed with A connecting shaft, three stirring blades are fixed around the rotating shaft, and the connecting shaft is constructed with helical blades from top to bottom, the rotation direction of the helical blades is the same as that of the rotating shaft, and several The spiral dents of the same rotation direction, the rotation direction of the spiral dents is opposite to the rotation direction of the rotating shaft. The liquid dispensing device for hemodialysis provided by the present invention realizes the circular agitation of the dialysis concentrate, improves the stirring efficiency and uniformity, and the stirring blade realizes the maximum stirring area; the structure of the spiral dent makes the heated dialysis concentrate Swirl upwards to create a vortex, avoid sedimentation and the dialysate is too cold.

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
