Cerebrospinal fluid automatic sample separation detection disc

Abstract

The invention relates to a cerebrospinal fluid automatic sample separation detection disc, belongs to the field of microbiological detection, and solves the problems of a long detection period and complex operation steps of existing cerebrospinal fluid bacteria enrichment culture. The cerebrospinal fluid automatic sample separation detection disc comprises a central collection area and collection colloidal gold test paper; the collection colloidal gold test paper is annularly arranged by taking the central collection area as a circle center, and each unit colloidal gold fan-shaped test paper is isolated from each other; the collection colloidal gold test paper comprises a sample pad, a combination pad, a detection pad, a water absorption pad and a bottom lining; and the detection pad is attached to a substrate, the combination pad is located on the detection pad and partially overlapped with the detection pad, the liquid absorption pad is located on the detection pad and partially overlapped with the detection pad, and the sample pad is located on the combination pad and partially overlapped with the combination pad. Samples are uniformly added through the central collection area, one-time detection of eight common bacteria infected in the cerebrospinal fluid is achieved, rapid and accurate detection can be performed in a short time through a double-antibody sandwich design, and great significance is achieved in the diagnosis and treatment process of central nervous system infection patients.

Description

technical field [0001] The invention relates to a cerebrospinal fluid automatic sampling detection disk, which belongs to the field of microorganism detection. Background technique [0002] Clinically, infectious neurological diseases such as suppurative meningitis and brain abscess caused by bacterial infection are common, and the diagnosis method is cerebrospinal fluid culture. After collecting cerebrospinal fluid samples, doctors usually need to go through the process of enrichment culture, separation and purification, and finally rely on colony morphology, biochemical identification, drug sensitivity test, immunological methods and other means to make diagnosis and differential diagnosis. The cerebrospinal fluid culture method is the current infectious disease. The "gold standard" in the diagnosis of neurological diseases. However, the detection process of cerebrospinal fluid culture is complicated, and the diagnosis period is long, usually one week. In the case of acu...
