Description

Back-flushing type dry powder packaging bag for dialysis

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a recoil formula dry powder wrapping bag is used in dialysis.

Background

Hemodialysis is the artificial removal of toxic waste, water and salts accumulated in a patient, and dialysate is an important component of hemodialysis.

Dialysis dry powder is required to be used as required, preparation environment and equipment are required to reach a certain clean level when the dialysis dry powder is prepared, and the concentration of the prepared concentrated solution has higher requirement, when the traditional dry powder bag is used, dialysis water is generally injected into the dry powder bag from a water inlet at the upper part of the dry powder bag, the dialysis water and the dialysis dry powder are mixed to form dialysis solution and then flow out from a water outlet, however, dialysis dry powder is accumulated at the bottom of the bag due to gravity, the water flowing from the upper part to the dry powder can wet the surface of the dry powder, the wetted part can form a layer of dry powder concentrated solution net which is connected with each other, the net has certain hydrophobicity, the net filling part can form a protective film which covers other dry powder to prevent other dry powder from being further infiltrated by water, so that agglomeration is formed, and as the dialysis water entering from the water inlet of the traditional dry powder bag cannot directly impact the dry powder, the dissolving speed of dry powder is very influenced after the dry powder is formed into blocks, and meanwhile, because part of dry powder bags are provided with water outlets at the bottoms of the bags, the outflow of dialysis concentrated solution is not facilitated after the dry powder is blocked, and the completeness and the safety of dialysis are very influenced.
