Body fluid enrichment culture bottle and preparation method thereof

Abstract

The invention discloses a body fluid enrichment culture bottle and a preparation method thereof. The bottle comprises a bottle body, a bottle plug, a bottle cap a sensor and a fluid medium. The bottle body is in a cylindrical shape. The sensor is attached to the bottom inside the bottle body. The bottle plug and the bottle cap achieve the sealing and mechanical protecting effects. The sealed space of the body fluid enrichment culture bottle is the negative pressure aseptic environment. The bottle body of the body fluid enrichment culture bottle is the dual-layer plastic bottle body, one layer is made of plastic materials with strength support, and the other layer is made of plastic materials with gas barrier effect. The two layers of plastic materials avoid breaking safety risk and breathability influences. Macromolecule silicone rubber materials in the sensor are solidified at high temperature, so that the preparation time and solidification time of the sensor are greatly shortened, and the time of the whole production process is shortened. The sensor is nontransparent due to an opacifying agent, light signal collection is not interfered, and then the sensitivity of automatic detection equipment is improved.

Description

technical field [0001] The invention relates to the technical field of clinical microorganism detection, in particular to a culture bottle for body fluid enrichment and a preparation method thereof. Background technique [0002] Body fluid culture is a microbiological detection method used to detect the presence or absence of microorganisms in human samples, including blood culture, sputum culture, urine culture and other body fluid (pleural effusion, ascites, cerebrospinal fluid, etc.) culture. For the rapid detection of sepsis and bacteremia, which are clinically serious and life-threatening, it is very important to determine whether there is microbial growth in the patient's body fluid for a clear diagnosis, and it is the key to effective clinical treatment. Therefore, the detection of pathogenic microorganisms in body fluids or the like should be carried out in the shortest possible time. In recent years, with the advancement of science and technology, the combination o...

Problems solved by technology

And according to the sensor described in the prior art has light transmission, and the detection principle used by the automatic detection equipment is the photoelectric detection principle, collects the optical signal, and then converts it into an electrical signal and transmits it to the control system. At this time, if the sensor has light transmission , will affect the acquisition of optical signals

[0006] In addition, in the prior art, the preparation and curing of the sensor takes a long time, generally within 24 hours to 48 hours, which seriously affects the production efficiency
