Hematodialytic concentrated solution conveying and filling system

Abstract

The invention discloses a hematodialytic concentrated solution conveying and filling system. The hematodialytic concentrated solution conveying and filling system comprises a solution preparation device, a liquid inlet decompression device, an intermediate workbin, a liquid outlet pressure stabilizing device, a conveying device, a filling device and a control device. The conveying device of a filling bucket feeding line, a primary conveying mechanism in a filling station and a secondary conveying mechanism after filling are operated independently. The filled empty buckets enter the primary conveying mechanism through the conveying device and are filled through the filling device, and are then pushed into the secondary conveying device through a pushing mechanism after filling. The conveying device, the primary conveying mechanism and the secondary conveying mechanism work simultaneously without a process of waiting for conveyance, so that the production efficiency is improved effectively. The outlet of the liquid preparation device is connected to the inlet of the intermediate workbin, and the liquid inlet decompression device is assembled on a conveying pipeline between the liquidpreparation device and the intermediate workbin, so that the liquid inlet pressure does not enter the intermediate workbin directly and is acted to the liquid inlet decompression device, and therefore, the liquid level stability during fill is guaranteed effectively.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a hemodialysis concentrate delivery and filling system. Background technique [0002] Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. It drains the blood from the human body to the outside of the body, and passes through a dialyzer composed of countless hollow fibers. The blood and the electrolyte solution (dialysate) with a similar concentration to the body are inside and outside the hollow fibers, through diffusion / convection. Exchange, remove metabolic waste from the body, maintain electrolyte and acid-base balance; remove excess water from the body at the same time, and return the purified blood to the whole process called hemodialysis. There are many problems in the existing hemodialysis concentrate conveying and filling system: one, the empty barrel of the filling line enters the filling position, the solu...

AI Technical Summary

Problems solved by technology

There are many problems in the existing hemodialysis concentrate conveying and filling system: one, the empty barrel of the filling line enters the filling position, the solution is filled, and the filling is completed and transported to the capping production line. The empty barrels on the line need to enter the filling station through the conveying line, wait for the filling to be completed, and then enter the conveying line through the conveying line to enter the next station. The production efficiency is low and cannot adapt to the development concept of industrialized mass production; It is sent to the filling machine through the liquid dispensing tank through the conveying pump for filling. It is easily affected by the pressure of the conveying pump and the liquid level of the dosing liquid during the conveying process, resulting in extremely poor stability of the liquid level during filling. Therefore, , there is an urgent need for those skilled in the art to develop a new type of hemodialysis concentrate delivery and filling system
