Embodiment Construction

[0021] Embodiments of the system for selecting the number of thin-walled hollow fibers and the corresponding terminals of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] The hemodialysis machine is divided into two parts: the blood monitoring alarm system and the dialysate supply system. Blood monitoring alarm system includes blood pump, heparin pump, arteriovenous pressure monitoring and air monitoring, etc.; dialysate supply system includes temperature control system, liquid distribution system, degassing system, conductivity monitoring system, ultrafiltration monitoring and blood leakage monitoring, etc. Partial composition. Its working principle is: the dialysis concentrate and dialysis water are prepared through the dialysis fluid supply system to prepare a qualified dialysis fluid, and through the hemodialyzer, it will perform solute dispersion, osmosis and ultrafiltration with the patient's blood drawn by the...

Abstract

The invention relates to a thin-wall hollow fiber number selection system and a corresponding terminal. The terminal comprises a plurality of fiber dialysis devices, wherein each fiber dialysis device comprises a shell and a preset number of thin-wall hollow fibers, the preset number of thin-wall hollow fibers are embedded in the corresponding shell, and the numbers of the thin-wall hollow fibers of various fiber dialysis devices are different; and a type selection device which is connected with a body type identification device and is used for selecting the corresponding type of fiber dialysis device based on a received human body entity volume. The thin-wall hollow fiber number selection system and the corresponding terminal are compact in logic and have a certain self-adaptive level. The dialysis device with the corresponding number of thin-wall hollow fibers is selected to execute dialysis operation on the basis of a volume estimation result of a human body to be dialyzed, so that different types of suitable dialyzers can be selected for human bodies with different body types.

Description

technical field [0001] The invention relates to the field of dialysis instruments, in particular to a system for selecting the number of thin-walled hollow fibers and a corresponding terminal. Background technique [0002] Hemodialysis, clinically means the removal of some waste products in the blood through a semi-permeable membrane. Hemodialysis is one of the safer, easier and widely used methods of blood purification. Dialysis is the movement of solutes from a solution of high concentration to a solution of low concentration through a semipermeable membrane. Hemodialysis includes the movement of solutes and water, that is, the blood and dialysate exchange substances in the dialyzer (artificial kidney) through semi-permeable membrane contact and concentration gradients, so that metabolic waste and excess electrolytes in the blood are transferred to the dialysate. Move, the calcium ions and bases in the dialysate move to the blood. If the mixture of albumin and urea is p...
