Description

Dry powder pre-dissolving device Technical Field The invention relates to the technical field of hemodialysis equipment, in particular to a dry powder pre-dissolving device. Background Along with the improvement of medical level, kidney disease patients are well continued under the popularization of dialysis auxiliary treatment, and under the condition of more dialysis patients, a multi-bed centralized liquid supply system is widely popularized, but in the use process, a plurality of problems such as bacteria exceeding standard and unstable liquid preparation concentration are generated, and particularly, the bacteriostasis problem of B concentrated liquid is always a great difficulty for limiting the development of equipment. The existing dialysis machine equipment also has the problem of unstable PH caused by crystallization, and the specific reasons are that the dialysis machine can be heated in the process of heat sterilization, repeated experiments show that trace NaHCO3 saturated solution remained at the tail end of the dialysis machine is easy to decompose into Na2CO3 when the dialysis machine is heated and sterilized in a pipeline, the NaHCO3 saturated solution is concentrated at the tail end of the heat sterilization and then meets carbon dioxide in the air, and the NaHCO3 is recrystallized to precipitate and is attached to a filter screen. Because the dialysis machine can not suck the concentrated solution B, the concentration of sodium ions is not set, after the equipment is used for adjusting up the adjustable sodium, fei Senyou S series hemodialysis machines can increase the suction amount of the concentrated solution A, so that the electric conductivity is increased, ions from the concentrated solution A partially replace ions of the concentrated solution B to restore the dialysis electric conductivity to be normal, but because the alkaline concentrated solution B can not be fully sucked, acetic acid in the concentrated solution A can not be neutralized, the PH value in the dialysate is reduced, and thus, acidosis reaction can occur to patients.
