Embodiment Construction

[0014] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments, which do not depart from the scope of protection of the present invention, and the description and drawings therein are essentially for illustrative purposes, not for Limit the invention.

[0015] The hemodialysis device of this embodiment is a device for daily treatment of patients such as uremia, not an emergency device, and the treatment time is usually about 4 hours.

[0016] Hereinafter, the structure of the hemodialysis apparatus of this embodiment will be described in detail.

[0017] Such as figure 1 As shown, the main working components of the hemodialysis device of the embodiment of the present invention include a heating chamber 2, gear pumps 31, 32, a first suction pump 51, a second suction pump 52, a third suction pump 53, a...

Abstract

The invention provides a hematodialysis device and method capable of automatically adjusting potassium ion concentration. The hematodialysis device comprises a balancing cavity, a dialyzer, a first liquid suction pump, a second liquid suction pump and a third liquid suction pump, wherein the first liquid suction pump is used for pumping liquid B so as to form first mixed liquid with reverse osmosis water, the second liquid suction pump is used for pumping first liquid A, the third liquid suction pump is used for pumping second liquid A, the first liquid A and the second liquid A are mixed to form second mixed liquid, the second mixed liquid enters a balancing cavity and then enters the dialyzer to perform interaction with blood of a patient. The first liquid A and the second liquid A are liquids different in potassium ion concentration, and the pumping proportions of the first liquid A and the second liquid A are adjusted by adjusting the pumping amounts of the second liquid suction pump and the third liquid suction pump, so that the actual concentration value of potassium ions in the second mixed liquid is consistent with a preset concentration value of potassium ions in the second mixed liquid.

Description

Technical field [0001] The invention relates to the technical field of dialysis equipment, in particular to a hemodialysis device capable of automatically adjusting the potassium ion concentration. Background technique [0002] Dialysis-related arrhythmia is a common complication of hemodialysis patients. It is common in atrial fibrillation and ventricular arrhythmia, which often affect the normal progress of dialysis. Hypokalemia during dialysis is one of the possible causes. Potassium is one of the important electrolytes in the human body. It is the main cation in the cell and the basic ion for the electrophysiological activity of myocardial cells. The normal potassium ion level is the basis for maintaining the electrophysiological activity of the heart. Most patients with uremia have hyperkalemia before dialysis. Severe hyperkalemia can easily induce cardiac arrest or even sudden death. However, during the dialysis process, potassium ions are cleared through the dialysis membr...
