Abstract

The invention discloses a double-path laser detection device for bacterial culture detection. The double-path laser detection device comprises a laser module, a light path deflection and adjustment assembly, a culture bottle, a detection circuit board and a culture bottle position adjustment mechanism. According to the invention, single-path laser output of a laser device is changed into double-path laser output through a one-to-two optical fiber patch cord; laser collimation and 90-degree deflection of a light path are achieved through the light path deflection and adjustment assembly, and laser penetrates through a culture solution-free area in the culture bottle and is received by an infrared detector on the detection circuit board after passing through internal gas; and the infrared detector converts a received laser signal into an electric signal as a signal basis for judging whether bacteria grow in the culture bottle or not. A single path of laser is divided into two paths of laser, so that synchronous detection of the two paths of laser is realized, the detection efficiency is improved, and the detection cost is reduced; and the light path deflection and adjustment assemblyrealizes 90-degree deflection and accurate adjustment of the light path, the size of the detection device is reduced, and the accuracy of a detection result is improved.

Description

technical field [0001] The invention relates to the technical field of analytical experiment equipment, in particular to a dual-path laser detection device for bacterial culture detection. Background technique [0002] Bacterial culture test is a microbiological examination method commonly used to detect the presence of bacteria in blood samples and food samples. There are no bacteria in the blood of a healthy human body. Once the blood is infected with bacteria, various discomforts may occur, such as bacteremia, sepsis, sepsis, etc., and severe cases may lead to death. Food contaminated by bacteria is prone to spoilage and cause foodborne diseases. [0003] By detecting the carbon dioxide gas produced during bacterial metabolism, it can be determined whether there is bacterial growth. The content of carbon dioxide gas can be detected effectively and rapidly by adopting tunable absorption spectroscopy technology. However, the current detection devices using tunable absorp...
