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 without departing from the protection scope of the present invention, and the description and drawings therein are used for illustration in essence, rather than for limit the invention.
[0015] The hemodialysis device of this embodiment is equipment for daily treatment of patients with uremia, not emergency equipment, 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 parts of the hemodialysis apparatus of the embodiment of the present invention include a heating chamber 2, gear pumps 31, 32, a first liquid suction pump 51, a second liquid suction pump 52, a third liq...

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 potassium ion concentration. Background technique [0002] Dialysis-related arrhythmia is a common complication in hemodialysis patients. Atrial fibrillation and ventricular arrhythmia are more common, 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 cells and the basic ion for the electrophysiological activities of cardiomyocytes. Normal potassium ion levels are the basis for maintaining cardiac electrophysiological activities. Most uremic patients have hyperkalemia before dialysis. Severe hyperkalemia can easily induce cardiac arrest or even sudden death. However, during dialysis, potassium ions are removed through the dialysis membrane and acidosis is correcte...
