Degassing device for preparing dialyzate

Abstract

The invention discloses a degassing device for preparing dialyzate. The degassing device comprises a degassing cavity, a choke degassing mechanism, a liquid level switch and a degasser pump, wherein the degassing cavity is provided with a liquid inlet pipe and a liquid outlet pipe; the liquid level switch is arranged in the degassing cavity; the choke degassing mechanism comprises a degassing pipe and a ball body; the degassing pipe is vertically arranged; the ball body is arranged in the degassing pipe; the degassing cavity is communicated with an inlet of the degassing pipe of the choke degassing mechanism; and the degasser pump is communicated with an outlet of the degassing pipe of the choke degassing mechanism. Compared with the prior art, the degassing device for preparing the dialyzate is rapid and effective in degassing, and is capable of guaranteeing the safety and the dehydration accuracy of dialysis treatment and dehydrating a proper amount of moisture liquid.

Description

technical field [0001] The invention relates to the field of blood setting in medical instruments, specifically a dialysate preparation and degassing device. Background technique [0002] Degassing is a very important part of the blood purification automatic dosing system, because the dialysate is prepared from reverse osmosis water and two concentrates (the concentrates contain NaCl, KCl, CaCl, MgCl2 and NaHCO3, etc.). Because in the process of dosing the dialysate, the reverse osmosis water is required to be heated first and then mixed with the two concentrates. However, after the reverse osmosis water is heated, a large number of air bubbles will be generated, and the air bubbles will flow into the dialysis membrane along the waterway, resulting in It will affect the accuracy of dehydration and threaten the life of the patient. In order to remove air bubbles in reverse osmosis water, it is necessary to introduce a degassing link. Degassing is generally done by negative ...

AI Technical Summary

Problems solved by technology

At present, there are certain defects in the degassing device of the prior art, that is, although the air bubbles in the liquid are removed, part of the liquid is also sucked away, which will not only affect the dosing effect of the dialysate, but also cause patients to Causes excessive dehydration during treatment of dialysis, which affects the treatment effect
