Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0013] Such as figure 1 As shown, a blood culture detection positive reporting device of the present invention includes a culture bottle 1 , a connector 2 and a carbon dioxide sensor 3 . The culture bottle 1 is filled with culture medium to collect blood samples. The mouth of the bottle is provided with a butyl rubber stopper 4, and the lower end of the connector is provided with a puncture needle 5. The puncture needle 5 pierces the butyl rubber stopper 4 and extends into the culture bottle 1. , so that the carbon dioxide gas in the culture bottle 1 is transmitted to the carbon dioxide sensor 3 through the hollow connector 2, and the carbon dioxide sensor 3 is connected to the computer 11 to analyze the change of the carbon dioxide concentration and give an alarm prompt.

[0014] Such as figure 2 As shown, the culture bottle 1 of the positi...

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...
