A support for bagged Escherichia coli test paper

Abstract

The invention discloses a bracket for bagged Escherichia coli test paper. The bracket comprises a base, a press strip and pre-brackets, wherein a fixed anti-slip belt and a V-shaped through hole are arranged at a transverse side surface of the base, the V-shaped through hole is disposed under the fixed anti-slip belt, and the lengths of the holes on both sides of the V-shaped through hole are notequal; the press strip and the pre-brackets are respectively disposed on the fixed anti-slip belt and the V-shaped through hole at the transverse side surface, the press strip is in a recessed shape,two ends of the press strip are connected to the longitudinal side surface of the base, the surface of the press strip facing the fixed anti-slip belt is provided with a moving anti-slip belt, and thepre-brackets are connected by the V-shaped through hole and an elastic connecting mechanism provided on the inner side of the transverse side surface; a strip-shaped through hole is formed at the longitudinal side surface of the base, the strip-shaped through hole includes a horizontal section and a vertical section, and both ends of the press strip are connected by the strip-shaped through holeand the longitudinal side surface. The bracket can reduce the operation steps of operators and reduce the risk of the person being infected by a sample, uses mechanical friction to substitute the operation of human hand, and reduces the risk of sample pollution due to personnel operation.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a bracket for bagged coliform test paper sheets. Background technique [0002] Coliform bacteria are a group of aerobic and facultative Gram-negative spore-free bacilli that can ferment lactose and produce acid and gas within 24 hours when grown at 37°C or 44°C. Generally, those grown at 37°C are called "total coliforms", and those grown at 44°C are called "fecal coliforms". Coliform bacteria are indicator bacteria of intestinal pollutants in warm-blooded animals such as humans and poultry, and reflect the situation that samples are contaminated by feces. [0003] The coliform test paper uses quantitative lactose, indicators, and nutrients to be adsorbed on a certain area of ​​sterile filter paper. When the bacteria multiply, the biochemical reaction of the coliforms changes the color of the indicator to determine whether the sample contains coliforms. Take bromocresol purple...

Problems solved by technology

The bag-like flexible packaging form, especially the multi-pack bag-like flexible packaging form (such as the test piece MPN counting method) has the following disadvantages during use: First, the shape of the soft material packaging is deformed, and the opening is easy to touch other items such as desktops and hands , so as to introduce pollution; second, analysts need to use both hands when using, one hand fixes the package and stretches the bag mouth, and the other hand takes samples and adds samples. When there are many samples, the operation steps are many and repeated, which is cumbersome and inconvenient; To vaccinate, the droplet splash is easy to make the personnel infected by the sample
