1, the hospital hemodialysis water purification equipment adopts unique two-stage reverse osmosis process, which can run for a long time in a safe, stable and energy-saving state;
2, power-on self-checking, water shortage protection alarm, automatic reset in case of power failure, high and low voltage protection, RO automatic rinsing, UV lamp failure alarm and other functions, to ensure the system safe operation;
3, the water quality, pressure, flow rate, continuous online monitoring display, to ensure the quality of produced water;
4, the front and rear stages of reverse osmosis system can be used separately to provide the maximum use of the system. Continuous online monitoring and display to ensure the quality of water production;
4, reverse osmosis system before and after the level can be used separately to provide maximum flexibility and to ensure the safety and stability of equipment operation;
5, the use of imported control valve body, microfiltration, reverse osmosis membranes, 4,500 Dalton ultrafiltration, UV lamps, mute high-pressure pumps, sanitary solenoid valves, etc., the performance of the product is maximized to ensure;
6, simple shape, small footprint, according to the different needs of customers tailor-made;
7, dialysis direct supply pipeline without any water storage device, the cycle of constant-pressure water supply, dual-channel water supply live water dialysis. (I) Treatment mode
Pre-dilution replacement method, post-dilution replacement method and mixed dilution method.
(ii) Prescription
1. A faster blood flow rate (recommended >250 ml/min) and dialysate flow rate (500-800 ml/min) are often needed to remove the right amount of solutes.
2. Replacement solution replenishment volume post-dilution replacement method for 15-25L, pre-dilution replacement method for 30-50L. In order to prevent the transmembrane pressure alarm, the replacement volume setting needs to be adjusted according to the blood flow rate. (I) Anti ultrafiltration
1. Causes Low venous pressure, low ultrafiltration rate, or the use of dialyzers with high ultrafiltration coefficients, at the outlet of the dialyzer, the pressure on the blood side may be lower than that on the dialysate side, resulting in counter-ultrafiltration, which can be severe enough to result in pulmonary edema in the patient. It is uncommon in clinical practice.
2. Prevention Adjust appropriate TMP (100-400 mmHg) and blood flow (often >250 ml/min).
(ii) Protein loss
The use of high-flux dialysis membranes has made albumin easy to lose, and albumin loss is increased when HDF therapy is performed, especially with post-dilution replacement.
(C) Deficiency syndrome
High-flux hemodialysis increases the loss of soluble vitamins, proteins, trace elements, and small-molecule polysomes. Therefore, timely nutritional supplementation should be provided when hemodialysis filtration therapy is performed
