Blood culture detection positive reporting device

Abstract

The invention relates to biological sample culture detection equipment and in particular relates to a blood culture detection positive reporting device. The blood culture detection positive reportingdevice comprises a culture bottle, a connector, a carbon dioxide sensor and a computer, wherein a culture medium is filled into the culture bottle and a blood sample is collected; a butyl rubber stopper is arranged on an opening of the culture bottle and is used for sealing the opening. The culture bottle is simple in structure and low in production cost; the connector has a hollow design and a puncture needle is arranged at the lower end of the connector and is used for puncturing the butyl rubber stopper at the opening of the culture bottle, so that a cavity of the culture bottle is communicated with the carbon dioxide sensor through the connector; a filtering membrane is arranged in a pipeline of the connector; an oxygen consumption bag can be additionally arranged to culture an anaerobic sample; the bag is internally provided with an oxygen consumption agent so that the growth of anaerobic bacteria is facilitated. The carbon dioxide sensor is communicated with the connector and isused for sensing a concentration change state of carbon dioxide in the culture bottle and judging a growth state of microorganisms in a culture solution; meanwhile, the carbon dioxide sensor is connected with the computer and a positive culture bottle is reported to an operator in a laboratory.

Description

technical field [0001] The invention relates to biological sample culture and detection equipment, in particular to a blood culture detection and positive reporting device. Background technique [0002] In hospital clinical and medical research trials, it is often necessary to perform bacterial culture on biological samples from patients. The current biological sample culture instruments on the market inject biological samples into culture bottles for bacterial culture. When bacteria are present in a biological sample, the bacterial metabolite CO 2 Will react with the moisture in the culture flask to produce H + or HCO 3 - Changes in ion concentration, these changes will cause changes in the indicators or fluorescent substances placed in specific parts of the bottle. The instrument reflects the growth status of microorganisms in the culture bottle through the color detection device and fluorescence detection device. After the personnel transmit the information, the alar...

Problems solved by technology

The advantage of this method is that it can automatically detect the growth information of bacteria in the culture bottle, but it also has the following defects: the production process of the blood culture bottle is complicated, which leads to the high price of the culture bottle
