Abstract

The invention discloses a novel self-cleaning system of a hemodialysis machine. A liquid drainage port of the hemodialysis machine is connected with a conductivity detector. The self-cleaning system comprises an RO water cleaning line, a sterilizing solution is infecting line and a controller. The RO water cleaning line comprises multiple branch RO water pipelines, each of which is connected with a liquid inlet of the hemodialysis machine through a first flow adjusting valve. The sterilizing solution disinfecting line comprises multiple branch sterilizing solution pipelines, each of which is connected with an input unit and a first electronic flowmeter. Each branch sterilizing solution pipeline is connected with the liquid inlet of the hemodialysis machine. A pressure alarm is connected between a delivery unit and the second flow adjusting valve. A diluent pipe is connected with a second electronic flowmeter used for metering diluents entering a sterilizing solution storage tank. The controller is used for controlling the RO water cleaning line and the sterilizing solution disinfecting line to switch for work. The novel self-cleaning system of the hemodialysis machine helps achieve large-scale, standard and intelligent cleaning operation.

Description

technical field [0001] The invention relates to medical equipment, in particular to a novel self-cleaning system of a hemodialysis machine. Background technique [0002] In recent years, due to environmental pollution and other reasons, the number of patients with renal failure and uremia has gradually increased. Hemodialysis is the most basic means to maintain the lives of patients. One of the main measures that patients rely on to continue their lives. [0003] The hemodialysis machine is composed of circuit and water circuit. The front panel is composed of 2-3 touch screens. From top to bottom, there are circuit, water circuit, blood circuit and corresponding control parts. Among them, the waterway part of the hemodialysis machine is very critical. It not only passes through the dialysate and reverse osmosis water, but also passes through the small molecule toxins and excess water removed from the patient. If the disinfection is not thorough, it is easy to cause cross-in...
