Water quality monitoring and constant-pressure sterilizing full-automatic water purifier suitable for highlands

Abstract

The invention relates to the technical field of clinical examination and analysis instruments, in particular to a water quality monitoring and constant-pressure sterilizing full-automatic water purifier suitable for highlands. The water quality monitoring and constant-pressure sterilizing full-automatic water purifier comprises a water storage tank, wherein a water inlet of the water storage tankis sequentially connected with a first PP (Polypropylene) filter, an electromagnetic valve, a first water pump and a water inlet switch; a water outlet of the water storage tank is sequentially connected with a second water pump, a second PP filter, a pressure regulating valve and a pressure gauge; the water storage tank is internally provided with a liquid level sensor, a water quality monitor and a timing UV (Ultraviolet) sterilizing lamp. According to the water quality monitoring and constant-pressure sterilizing full-automatic water purifier disclosed by the invention, the purpose of supplementing deions is achieved by controlling the water pumps and the electromagnetic valve to move by using an information collection mode of the liquid level sensor, constant pressure, filtering by deionized water, water quality monitoring and sterilizing are realized, more functions can be realized by using fewer hardware modules, and the practicability of equipment is enhanced; on the other hand,the requirements of an instrument can be completely met by simplifying equipment composition, and the manufacturing cost of the equipment is reduced, so that the using threshold is reduced, and the popularization possibility of the equipment is increased.

Description

technical field [0001] The invention relates to the technical field of clinical testing and analysis instruments, in particular to a fully automatic pure water device for water quality monitoring and constant pressure sterilization adapted to plateaus. Background technique [0002] Fully automatic biochemical and immunological instruments are equipped in every hospital in my country. During the use of the equipment, a large amount of deionized water is needed to clean the sample needles, reagent needles, reaction cups, stirring rods, washing stations, and liquid circuits. Since the average altitude of Tibet is about 3800m, the air pressure is roughly maintained at 450mmHg, which is equivalent to 0.59 standard atmospheric pressure. Since the laboratory uses a central water supply system, the pressure decays during the transportation process. Bacteria and algae are easy to breed in the pipeline and the liquid path of the instrument, especially the water bath constant temperatur...

Problems solved by technology

Since the average altitude of Tibet is about 3800m, the air pressure is roughly maintained at 450mmHg, which is equivalent to 0.59 standard atmospheric pressure. Since the laboratory uses a central water supply system, the pressure decays during the transportation process. Bacteria and algae are easy to breed in the pipeline and the liquid path of the instrument, especially the water bath constant temperature tank. Once the growth of bacteria, algae, flocs, etc. leads to the failure of optical path absorption, resulting in incomplete cleaning of light absorption and various components, inducing cross-contamination of test items, inaccurate test results for patient samples, and frequent shutdown of the instrument, resulting in loss of reagents , and delay the detection time of patients, especially for some critically ill patients with few plasma samples, blood must be drawn again, causing great pain to patients
