Problems solved by technology

[0004] The technical problem to be solved by the present invention is that luciferase has poor stability and is easily inactivated. It is necessary to add a stabilizer to strengthen its stability, prolong its shelf life and improve the application value of the product. However, the existing swab has a simple structure. There is no structure for separately storing the reaction solvent, and the purpose is to provide a two-chamber composite component ATP detection swab, so that it has two cavities at the end of the storage reaction solution, one cavity holds the enzyme solution containing a stabilizer, and the other cavity Reaction buffer in chamber

Embodiment 1

[0028] Such as Figure 1~4As shown, the present invention provides a two-chamber composite component ATP detection swab, including a tube base 1, a reaction tube 2, a liquid storage cap 3, a hollow rod-shaped cotton swab 4 and a cotton ball 5, and a liquid storage cap 3 Including the first chamber 6 and the second chamber 7, the axial bottom end of the first chamber 6 is connected to the axial top end of the tube base 1, and the axial top end and the axial bottom end of the second chamber 7 pass through the partition 8 connection; the partition 8 is provided with a through hole 9, and the through hole 9 is provided with a sealing plug 10; the first chamber 6 is used to hold the reaction buffer, and the second chamber 7 is used to store the enzyme containing the stabilizer liquid. A thimble rod 11 is arranged inside the pipe base 1, the axis lines of the thimble rod 11, the axis line of the pipe base 1 and the axis line of the through hole 9 are all coincident, and the upper e...

Embodiment 2

[0030] Further improvement on the basis of Example 1, the inside of the first chamber 6 is an inverted conical structure, the density of the sealing plug 10 is less than the density of the enzyme solution containing the stabilizer contained in the second chamber 7, and the through hole The inner diameter of 9 is greater than the outer diameter of thimble rod 11.

[0031] Example 2

[0032] Further improvement on the basis of Example 1, the bottom end surface of the tube base 1 is provided with a tapered opening 16 along the circumference of the thimble rod 11, and the top of the cotton swab stick 4 is sleeved and connected with the thimble rod 11 through a transition fit, and the cotton swab The inner cavity of the rod 14 communicates with the liquid flow channel of the thimble rod 11 . The end side wall of the thimble rod 11 located at the tapered opening 16 is provided with a rubber sealing ring along the circumferential ring, and the cotton swab stick 4 is sleeved on the t...

Abstract

Disclosed is a two-chamber-combined composite assembly ATP detection swab. A liquid storage cap comprises a first chamber and a second chamber, wherein the bottom end of the first chamber is connectedto the top end of a tube base, and the top end of the first chamber is connected to the bottom end of the second chamber via a baffle plate; the baffle plate is provided with a through hole, which isprovided with a sealing plug; the upper end of an ejector pin rod passes through the bottom of the first chamber, extends into the first chamber, and is located below the sealing plug; the lower endof the ejector pin rod is a hollow rod section, the side wall of which is provided with a plurality of holes, liquid flowing pipes are formed between the holes and the bottom rod section of the ejector pin rod, and the holes are located between the bottom end of the first chamber and the top end of the tube base; and external force is applied to make the ejector pin rod further extend into the first chamber, the rod section where the holes are extends into the first chamber, and the top end of the ejector pin rod passes through the through hole, jacks the sealing plug up, and enters the secondchamber. The swab has two chambers at the end that stores a reaction liquid, which is convenient for separately storing reaction solvents. The reaction solvents are mixed before detection, and then detection is carried out. The swab is simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to a microorganism detection device, in particular to an ATP detection swab with two chambers combined with a composite component. Background technique [0002] ATP is the direct source of energy for all life activities in cells, exists in all cellular organisms and its content is relatively stable. Due to the universality and stability of ATP, we can indirectly measure the residual amount of microorganisms by detecting the content of ATP in cells. The ATP fluorescence detection swab is used with the ATP bioluminescent instrument. It is suitable for global food processing enterprises, hospitals, restaurants, supermarkets and other manufacturing industries. It can quickly measure the cleanliness and hygiene status of surfaces and water samples, and confirm HACCP / SSOP procedures. , thus ensuring food safety, improving product quality and reducing costs. [0003] Due to the poor stability of luciferase and easy inactivation, it is ...
