Abstract

The invention relates to a closed bicarbonate hemodialysis tank, comprising a tank body (1), a tank mouth (1-1) is arranged on the upper part of the tank body, and an inner cover (2) is arranged at the tank mouth (1-1) And outer cover (3), it is characterized in that: inner cover (2) is provided with conduit (2-2), the upper end (2-2a) of conduit (2-2) passes inner cover (2) and outer cover ( 3) connected to the top inner wall; the top of the outer cover (3) is provided with an upwardly protruding convex cavity (3-1); the top of the outer cover (3) is frusto-conical or columnar, and the outer cover (3) ) is closed at the top. The present invention can be carried out in a closed environment during use, and can prevent CO2 from escaping and dialysate from being polluted. At the same time, it also has the characteristics of good sealing effect, fast and stable infusion speed, large volume, not easy to be damaged, and convenient for transportation and storage. .

Description

Technical field: [0001] The invention relates to a closed bicarbonate hemodialysis tank, which belongs to the technical field of packaging equipment for hemodialysis fluid. Background technique: [0002] The process of hemodialysis is the exchange of blood with the solute in the dialysate through the dialysis membrane, so as to remove the metabolic waste of the human body and correct the state of water, electrolyte and acid-base balance. With the development of hemodialysis technology, bicarbonate hemodialysis is widely used in clinical practice. How to ensure the treatment quality of bicarbonate hemodialysis requires good machines and good quality dialysate. Bicarbonate hemodialysis is mainly is guaranteed CO 2 stable before making the HCO 3 - Stablize. At present, domestic medical units that use bicarbonate hemodialysis fluid use the dialysate in an open state, resulting in CO in bicarbonate hemodialysis fluid 2 Escaping easily, resulting in HCO 3 - Decline, affecti...
