Abstract

The invention discloses a device applied to hemodialysis. The device comprises a liquid purifying assembly adopting a reverse osmosis membrane water purifying technology and a dialysate regeneration system and method combining with an adsorbent box body containing a specific adsorption material and/or a non-specific adsorption material, wherein the specific adsorption material in the adsorbent boxbody is mainly used for adsorption of urea in dialysis liquid and has not any chemical change in adsorption, and no ion accumulation is produced. The non-specific adsorption material in the adsorbentbox body is used for removing trace metal ions, creatinine, beta2M uric acid, trace organic substances and other substances in the dialysis liquid. The dialysis liquid is subjected to impurity removal through the adsorbent box body, then flows into the liquid purifying assembly and further is purified through a reverse osmosis membrane for follow-up circulation. The cost can be greatly reduced, water is saved, and the device is portable, small, exquisite and flexible to move and can simultaneously meet the demands of patients in hospitals and at home.

Description

Technical field [0001] The present invention provides a device applied to hemodialysis, which is used for the regeneration and recycling of dialysis liquid in a hemodialysis system, including a portable system using an adsorbent cartridge with adsorbent material and a liquid purification device, more specifically , The present invention relates to a patient's hemodialysis process. Background technique [0002] Chronic kidney disease (CKD) may be a sudden or gradual loss of kidney function. As the disease continues to worsen, patients with severe renal failure will have many symptoms. If not treated, it will eventually lead to death. The most severe stage of CKD is end-stage renal disease (ESRD). ESRD, also known as renal failure, is a physical condition in which a person's kidneys cannot adequately remove toxins, waste products, and excess fluid and maintain proper electrolyte levels. [0003] Current CKD treatments try to manage comorbidities and, if possible, slow the progressi...
