Description
Technical Field
The utility model relates to biological sample culture detection equipment, in particular to a biological sample culture device capable of instantly detecting carbon dioxide in a bottle.
Background
In hospital clinical and medical research trials, bacterial culture of biological samples of patients is often required. The biological sample culture apparatus on the market is to inject a biological sample into a culture flask for bacterial culture. When bacteria exist in a biological sample, the metabolite CO of the bacteria 2 Will react with the water in the culture flask to generate H + Or HCO 3 - The change of ion concentration can cause the change of indicator or fluorescent substance placed at specific position in the bottle, the instrument reflects the growth state of microorganism in the culture bottle by means of color detection device and fluorescent detection device, and the instrument transmits information to operator by means of computer algorithm, and then gives alarm to prompt the operator to make next operation. The method has the advantages that the method can automatically detect the bacterial growth information in the culture bottle, and the existing culture detection bottle is provided with a connector at the bottle mouth, and the metabolic product CO of bacteria is connected with the connector 2 And transmitting the detection result to a detection device for detection. The product with the structure has the defects of complex structure and long time for detecting the sun-reporting. Therefore, the utility model of the biological sample culture device capable of detecting the carbon dioxide in the bottle in real time is very beneficial.
Disclosure of Invention
In order to solve the problems, the utility model provides the novel biological culture detection bottle which has a simple structure and can timely and directly sense the change information of the carbon dioxide concentration in the culture bottle.
The technical scheme adopted by the utility model is as follows: it includes sample dish (2) and places blake bottle (1) on sample dish (2), its characterized in that: an optical signal transmitting device (3) is arranged at a bottle top space corresponding to the culture bottle (1) on the sample tray (2), an optical signal receiving device (4) is arranged at one side corresponding to the optical signal transmitting device (3) at the bottle top space, a magnetic stirring device (5) is arranged at the bottom of the culture bottle (1), and a liquid culture medium and a stirring rod (6) are arranged in the culture bottle (1). The bottom of the magnetic stirring device (5) is provided with an anode rotor (7).
When the utility model is used, the culture bottle is filled with a liquid culture medium, and when bacteria exist in a biological sample, the bacteria grow and reproduce in the culture medium and are metabolized to generate carbon dioxide. The optical signal transmitting device (3) transmits an optical signal with a specific wavelength for specific absorption of carbon dioxide, the optical signal receiving device (4) receives the optical signal with the specific wavelength transmitted by the transmitting device, the loss of light intensity is the absorption of carbon dioxide, and the concentration of the carbon dioxide in the culture flask is calculated according to the information. And then the growth and the growth condition of bacteria in the culture flask can be accurately judged through an algorithm.
The utility model has the advantages of simple structure and low production cost; the change condition of the carbon dioxide concentration in the culture flask can be detected directly in time and quickly, and the alarm is given through a computer.
