Automatic blood culture system calibration device

Abstract

The invention discloses an automatic blood culture system calibration device which comprises a data receiving terminal and a plurality of calibration units, wherein the calibration units comprise upper housings, lower housings, charge couplers, optical sensors, temperature sensors and calibration circuits; and the data receiving terminal comprises a display module, a control key and a receiving circuit. The automatic blood culture system calibration device can substitute a reference culture as an automatic blood culture system calibration medium, and is stable and reliable in performance; during calibration operation, a reference culture positive culture solution and many blood culture bottles are not required to be prepared; the use cost is low; a reason for false negative in a blood culture system can be found effectively; synchronous calibration of optical parameters and temperature parameters can be achieved; the calibration time is saved; and the device is relatively wide in application range.

Description

technical field [0001] The invention belongs to the technical field of quality control of an automated blood culture system, and in particular relates to a calibration device for an automated blood culture system. Background technique [0002] The automated blood culture system (hereinafter referred to as the blood culture system) is a method that adopts the principle of fluorescence method or photoelectric chromogenic method, and is used in clinical laboratories to continuously culture microorganisms in human blood or other sterile body fluids in vitro. 1. A system for automatically detecting and judging the culture result (positive or negative), the system includes a blood culture instrument and a matching culture medium. Due to the wide application of the blood culture system in the field of microbiological analysis in clinical testing and the frequent provision of testing data, it is necessary to calibrate it. [0003] Although the calibration of the current blood cultu...
