A six-way liquid distribution valve for glycated hemoglobin analyzer

Abstract

The invention provides a six-liquid-path distribution valve for a glycosylated hemoglobin analysis meter, and belongs to the field of glycosylated hemoglobin analysis meters. The six-liquid-path distribution valve comprises a gland, a support matched with the gland, an upper valve element, a lower valve element and a motor, wherein the upper valve element and the lower valve element are arranged between the gland and the support and are in end face attachment, and the motor is arranged below the support and used for driving the lower valve element to rotate. A rotary shaft is arranged on a motor shaft of the motor. A coupling used for transmitting the torque and rotating angle of the motor is further arranged between the rotary shaft and the lower valve element. A mispointing prevention column is arranged at the upper end or / and the lower end of the coupling. An upper inserting groove in fit and inserted connection with the upper end of the coupling is formed in the bottom of the lower valve element. A lower inserting groove in fit and inserted connection with the lower end of the coupling is formed in the rotary shaft. A positioning hole corresponding to the mispointing prevention column is formed in the upper inserting groove or / and the lower inserting groove. The mispointing prevention column is inserted in the positioning hole. Compared with the prior art, the coupling and the mispointing prevention column are adopted in the six-liquid-path distribution valve, the motor precisely drives the lower valve element to rotate, and assembly errors between the lower valve element and the motor are avoided.

Description

technical field [0001] The invention relates to a glycated hemoglobin analyzer, in particular to a six-way liquid distribution valve for the glycated hemoglobin analyzer. Background technique [0002] Clinical studies on diabetes control and complications have shown that the content of glycosylated hemoglobin (HbA1c) can reflect the average blood sugar level in the human body 2 to 3 months before the measurement, and has important clinical significance for the evaluation of blood sugar control programs and blood sugar control levels of diabetic patients. The gold standard for diabetes diagnosis. The criteria of the American Diabetes Association (ADA) have included HbA1c ≥ 6.5% as one of the criteria for diagnosing diabetes. With the improvement of living standards, the number of diabetic patients in my country has increased sharply, and the importance of glycosylated hemoglobin analyzers in clinical testing has become increasingly prominent. [0003] The liquid flow path d...
