Problems solved by technology

[0004] The traditional hemodiafiltration machine can only perform one of pre-replenishment or post-replenishment hemodiafiltration. The specific principle is as follows: figure 1 As mentioned above, after the infusion fluid is drawn from the outlet 1, it passes through the infusion pump 2 and is connected to the arterial jug 5 (such as figure 1 shown in the solid line) or connected to the venous pot 6 (such as figure 1 Dotted line in the middle), and the rate of fluid infusion cannot be changed during the treatment
Due to the lack of flow rate calculation methods for simultaneous fluid infusion, traditional hemodiafiltration machines can only complete hemofiltration or hemodiafiltration treatment with a single fluid infusion

Abstract

The invention discloses a hemodialysis filter allowing simultaneous front and back liquid supplementing. The hemodialysis filter comprises a liquid supplement outlet, a first liquid supplement pump, a second liquid supplement pump, a blood pump and a control device; the first liquid supplement pump and the second liquid supplement pump are both connected to the liquid supplement outlet; the first liquid supplement pump is connected with an arteriosus pot; the second liquid supplement pump is connected with a venous pot; the blood pump is connected with the arteriosus pot; the control device is used for controlling the speed of the first and second liquid supplement pumps so as to control the speed of front liquid supplement, the speed of back liquid supplement and total speed of liquid supplement for the liquid supplemented to both the arteriosus pot and the venous pot. The hemodialysis filter has the advantages that front liquid supplementing and back liquid supplementing can be completed at the same time according a proportion for hemodialysis therapy, the liquid supplement proportion and liquid supplement volume are automatically adjusted according to physiological status of a patient and various operating indexes during the therapy, and optimal therapeutic effect is achieved.

Description

technical field [0001] The invention relates to the technical field of dialysis equipment, in particular to a hemodialysis filtration machine capable of simultaneous liquid replenishment before and after. Background technique [0002] Hemofiltration (HF) technology is to make blood flow through a filter in the extracorporeal circuit through a machine (pump) or the patient's own blood pressure, and filter out a large amount of liquid and solute under the action of filtration pressure, that is, ultrafiltrate (ultrafiltrate) ), at the same time, replenish the electrolyte solution similar to the plasma liquid composition, that is, the replacement fluid (substitute), in order to achieve the purpose of blood purification. At the same time, traditional hemofiltration treatment can only complete one of pre-infusion (arterial jug rehydration) or post-infusion (venous jug rehydration), and cannot complete pre-infusion and post-infusion hemofiltration at the same time in proportion. ...
