Problems solved by technology

However, a serious problem is that ATP, as a typical energy source of life, not only exists in microorganisms, but also generally exists in animals and plants. Therefore, there is a certain amount of free ATP in the environment, and this part of ATP will cause damage to the measurement. greater impact

Embodiment 1

[0034] figure 1 Schematically shows the structural diagram of the integrated sampling device of the embodiment of the present invention, as figure 1 As shown, the integrated sampling device includes:

[0035] A sampling tube 11, the side wall of the sampling tube has a first through hole 12 and a second through hole 13, the height difference H>0 between the first through hole 12 and the second through hole 13;

[0036] figure 2 Schematically provides a top view structure diagram of at least two cavities in the embodiment of the present invention, such as figure 2 As shown, the at least two cavities 21, 31, 51, 61 are arranged on the outer edge of the sampling tube 11, and the walls of the at least two cavities opposite to the outer wall of the sampling tube 11 have a third channel hole 22 and a fourth through hole 23; when the at least two cavities 21 rotate around the sampling tube 11 so that the third through hole 22 corresponds to the first through hole 12, the fourth ...

Embodiment 2

[0043] An application example of the integrated sampling device and method according to Embodiment 1 of the present invention in the detection of microorganisms in liquid.

[0044] In this application example, at least two cavities are filled with ATP digestion enzyme solution, ATP digestion enzyme inhibitor solution, extractant solution, luciferin, and luciferase solution in sequence; the specific detection process includes the following steps:

[0045] (A1) Use an integrated sampling device to sample liquid, immerse the constant volume cavity at the bottom of the integrated sampling device into the liquid, then keep the sampling part as vertical as possible, shake the sampling device vigorously, and the liquid in the constant volume cavity will flow from the first Five small holes enter the sampling tube and enter the reaction tube;

[0046] (A2) Rotate the cavity so that the marking position on the sampling tube corresponds to the marking position of the cavity containing t...

Abstract

The invention discloses an integrative sampling device and a working method thereof. The integrative sampling device comprises a sampling pipe, at least two cavities and a constant volume cavity; the side wall of the sampling pipe is provided with a first through hole and a second through hole, and the height difference H between the first through hole and the second through hole is larger than zero; the cavities are formed in the outer edge of the sampling pipe, and the walls, opposite to the outer wall of the sampling pipe, of the cavities are provided with third through holes and fourth through holes; when the cavities rotate around the sampling pipe to enable the third through holes to correspond to the first through hole, the fourth through holes correspond to the second through hole; the constant volume cavity is formed in the sampling pipe and located on the lower portions of the cavities. The integrative sampling device and the working method thereof have the advantages that the structure is simple and the cost is low.

Description

technical field [0001] The invention relates to microorganism detection, in particular to a sampling device and a working method thereof for water sample microorganism detection and solid surface cleanliness characterization sanitation detection. Background technique [0002] In the field of hygiene such as food, "Hazard Analysis and Critical Control Point" (HACCP) is increasingly recognized worldwide. The HACCP system promotes organizations to reduce waste and reduce product costs through process improvement. It controls the key points of hazards in the production process of each batch of products, and provides multiple safeguard measures, so that it can effectively reduce the occurrence of unqualified food, reduce product loss and inspection costs. Therefore, no matter for the food safety of the public or the enterprise itself, it is a win-win situation. However, for HACCP, timeliness is very important, but in food and other hygienic fields, the detection of microbiologi...
