Dilution method and device for blood cell analyzer using concentrated diluent

Abstract

The invention relates to a method and device for diluting a concentrated diluent used by a blood cell analyzer. The device comprises an upper water tank (8) connected with a lower water tank (11) through a connecting solenoid valve (9), wherein the upper water tank (8) is connected with a pure water maker (2) through a water injection solenoid valve (3) and a concentrated diluent bag (13) through a peristaltic pump (16); an upper water tank liquid level probe (14), a stirring device (22), a detecting system and a constant temperature system are arranged on the upper water tank (8); the detecting system is composed of a conductivity detecting electrode (15) and a PH meter probe (19); the constant temperature system is composed of a heater (23), a temperature protection switch (5) and a temperature sensor (6); and a lower outlet (12) of the lower water tank (11) is connected with a diluent inlet (1) of the blood cell analyzer through a pipe and is provided with a lower water tank liquid level floater sensor (10). The concentrated diluent in small bags can be automatically diluted into common diluent applicable to the analyzer at a user terminal, so that the logistics cost is greatly saved, and the user experience is not influenced through the automatic diluting process.

Description

Technical field [0001] The invention relates to the technical field of human blood testing instruments, in particular to a dilution method and device for a blood cell analyzer using concentrated diluent. Background technique [0002] The blood cell analyzer is a medical precision instrument used to measure the relevant information of blood cells. In daily use, the diluent is the main diluent in the testing process and the main cleaning agent in the instrument maintenance process, so the daily consumption of the diluent is relatively large. At present, when the instrument is used, the pipette of the instrument is directly inserted into the ordinary diluent barrel packed in a large barrel, and the barrel is replaced after each use. The common packaging of ordinary diluent is 20L per barrel. Generally, one barrel needs to be replaced in 5-6 days. Therefore, users often buy ordinary diluent or buy a large quantity at a time. The weight and volume of ordinary diluent are calculated a...

Problems solved by technology

The common packaging of ordinary diluent is 20L per barrel, and a barrel needs to be replaced in 5-6 days, so users often need to buy ordinary diluent or buy in large quantities at one time. Calculate according to the weight and volume of ordinary diluent, and its logistics and transportation The cost is very high, which undoubtedly increases the user's use cost
