Abstract

The invention relates to the technical field of hematodialysis devices, discloses a dialysis water endotoxin filter and aims at overcoming the defect that existing dialysis water is possibly polluted before the dialysis water flows into a dialysis machine. The dialysis water endotoxin filter comprises a housing, wherein a first ultra-filter membrane tow and a second ultra-filter membrane tow which are mutually independent are arranged in the housing, an opening of the first ultra-filter membrane tow is fixed at the water inlet end of the housing through a sealing adhesive, an opening of the second ultra-filter membrane tow is fixed to the water outlet end of the housing through a sealing adhesive, an airtight space is formed inside the housing through sealing of the sealing adhesive at the two ends, a water inlet end cap and a water outlet end cap are installed at the water inlet end and the water outlet end of the housing respectively, the water inlet end cap and the water inlet end of the housing form a water inlet cavity, the water outlet end cap and the water outlet end of the housing form a water outlet cavity, and the water inlet end cap and the water outlet end cap are respectively provided with a water inlet connecting pipe and a water outlet connecting pipe. The dialysis water endotoxin filter is simple in structure, convenient to install and good in filtering effect, and the quality of dialysis water is guaranteed through a pre-filter of a dialysis machine.

Description

technical field [0001] The invention relates to the technical field of hemodialysis equipment, in particular to an endotoxin filter for dialysis water. Background technique [0002] Hemodialysis is mainly used to treat diseases such as chronic renal failure, acute renal failure and drug poisoning, and has been widely used clinically. Hemodialysis is to introduce the patient's blood and dialysate into the dialyzer in opposite directions at the same time, and flow through the two sides of the dialysis membrane respectively. The solute and water on both sides move across the membrane under the concentration and pressure gradient for material exchange. Patients undergoing hemodialysis or hemodiafiltration can appropriately prolong life and improve quality of life. During the hemodialysis process, related equipment such as a dialysis machine, a dialyzer, a dialysate, and a dialysis circuit are required. Among them, the dialysate is in direct contact with the patient's blood thr...
