Problems solved by technology

[0003] Most of the existing blood microbial culture bottles are glass bottles, which are not easy to transport and store
The utility model patent No. 200420048077.8 discloses a blood microbial culture bottle, which is filled with a mixed gas inside, which is not easy to implement, and the chemical sensor at the bottom is a carbon dioxide sensor, which is not sensitive enough for the detection of microorganisms with weak gas production. The macromolecular substances contained in it are also prone to interference

Embodiment Construction

[0037] The present invention is further described below with reference to the accompanying drawings and embodiments, but is not intended to limit the present invention.

[0038] see figure 1 , figure 1 It is a schematic diagram of the structure of the blood microorganism culture bottle of the present invention. The blood microorganism culture bottle includes a bottle body 1 , a bottle cap 2 , a chemical sensor 3 , a liquid culture medium 4 , and an adsorption resin 5 . The closed space in the culture bottle is negative pressure. The bottle cap 2 is double-layered, the outer layer is an aluminum-plastic composite cap, and the inner layer is a butyl rubber stopper to ensure the distinction between used culture bottles and unused culture bottles, and facilitate aseptic operation.

Abstract

The invention discloses a blood microorganism culture flask which comprises a flask body, a flask cover, chemoreceptors, a liquid culture medium and an absorption resin, wherein an asepsis environment is provided in the culture flask; the flask body is a cylindrical plastic container; a layer of chemoreceptors are arranged at the bottom of the flask body; the chemoreceptors are high-molecular polymer semipermeable membranes which are solidly adhered to the flask bottom. By utilizing the culture flask provided by the invention, a technical difficult problem of a full-automatic blood culture instrument is solved, full-automatic culture and detection on blood microorganism are realized, the detection sensitivity is improved, and the positive detection time is shortened.

Description

technical field [0001] The present invention relates to a medical testing device, in particular, to a blood microorganism culture bottle. Background technique [0002] Bacterial culture and testing of blood samples is a must for diagnosing blood infections. Sepsis and bacteremia caused by the invasion of blood by microorganisms are clinically critical illnesses. Whether patients with blood-infectious diseases can be effectively cured or not depends to a large extent on the rapid, timely and accurate bacterial culture test report. In the past, traditional manual culture and detection methods, static culture and naked eye observation, have the disadvantages of long microbial culture time, poor accuracy, and high contamination rate, which often delays treatment and cannot meet the needs of modern clinical medicine. The use of automated blood microbial culture can realize closed dynamic constant temperature culture, instrument detection, positive samples can be detected within ...
