A water pressure detection device for water making equipment for hemodialysis

Abstract

The invention discloses a water pressure detection device of a water production device for hemodialysis. The water pressure detection device comprises a secondary filtering device (1), a pressure gauge (2), a product water conveying pipeline (4), a constant pressure pipeline (5) and a controller (9); the pressure gauge (2) is arranged on a pipeline which is arranged between the secondary filtering device (1) and the product water conveying pipeline (4); the constant pressure pipeline (5) is provided with a circulating high-pressure detection switch (6) and an automatic pressure regulating valve (7); a valve (8) is arranged beside the automatic pressure regulating valve (7); each end of the valve (8) is communicated with the corresponding end of the automatic pressure regulating valve (7) through a water pipe. According to the water pressure detection device of the water production device for the hemodialysis, the water pressure output from the secondary filtering device is checked through the pressure gauge, the set pressure in the constant pressure pipeline is detected through the circulating high-pressure detection switch, the structure is simple, and the response is rapid.

Description

technical field [0001] The invention relates to water-making equipment for hemodialysis, in particular to a water pressure detection device for water-making equipment for hemodialysis. Background technique [0002] The water making equipment for hemodialysis is a water treatment equipment specially required for hemodialysis. Patients may be exposed to more than 300L of water per week through the hemodialyzer or the semipermeable membrane of the hemodialysis filter. While a healthy person rarely consumes more than 12 liters of water per week, the amount of contact with water increases nearly 30 times. Therefore, water quality should be controlled and monitored to avoid excess of known or estimated harmful substances. The water used to prepare the dialysate is usually treated to a certain extent, and the water quality meets the specified requirements. The equipment performance of the water treatment system depends on the water quality of the raw water and the function of the ...

Problems solved by technology

[0003] Under the existing technical conditions, the existing hemodialysis equipment, after pressure regulation and filtration, eliminates the possibility of secondary pollution through the double-port pressure pack, without further processing of the water pressure, if the previous equipment causes water pressure fluctuations The range is large, which may exceed the water pressure that the patient can bear, affecting the use of the patient
