Hereinafter, the operation process of the disinfection unit 400 will be described with reference to FIGS. 8 to 11.

In the initial state (FIG. 8), when the user presses the button 430, the piston 440 moves from the top to the bottom of the piston mounting space 412, and at this time, the piston elastic body 450 is compressed (FIG. 9) .

In this way, when the piston 440 moves from the top to the bottom of the piston mounting space 412, the internal pressure of the disinfectant fluid flow space 413 communicating with the piston mounting space 412 increases, and at this time, the disinfectant fluid flow space 413 increases. When the internal pressure of (413) rises, the second valve (470) mounted in the second valve mounting space (415) communicating with one side of the disinfectant flow space (413) is opened (at the fifth protrusion 425). (opens the communication hole formed on the other side of the second valve mounting space 415), the first valve 440 mounted on the first valve mounting space 414 communicating with the other side of the disinfectant flow space 413 is closed or It is maintained in a closed state (the communication hole formed on the other side of the second valve mounting space 415 by the third protruding jaw 423 is closed) (FIG. 9).

Accordingly, the internal pressure of the disinfectant flow space 413 changes to be the same as the internal pressure (atmospheric pressure) of the through hole 110, and when the internal pressure of the disinfectant solution flow space 413 becomes the same as the internal pressure of the through hole 110, Since external force does not act on the second valve 470, the second valve 470 is closed by the second elastic body 473 (the second opening and closing member 471 is closed by the fifth protruding protrusion 425). Close the communication hole formed on the other side of the valve mounting space 415 (not shown).

In this state, when the pressing force acting on the button 430 is released, the piston 440 moves from the lower part of the piston mounting space 412 to the upper direction due to the elastic force of the piston elastic body 450, and moves into the disinfectant fluid flow space 413. The internal pressure decreases (Figure 10).

At this time, when the internal pressure of the disinfectant fluid flow space 413 decreases, the second valve 470 mounted in the second valve mounting space 415 communicating with one side of the disinfectant fluid flow space 413 remains closed, The first valve 440 mounted in the first valve mounting space 414 communicating with the other side of the disinfectant flow space 413 is opened (the second valve mounting space 415 by the third protruding protrusion 423). (opening of the communication hole formed on the other side), the disinfectant solution (L) stored in the disinfectant storage unit 416 passes through the first valve mounting space 414 and flows into the disinfectant fluid flow space 413 and the piston mounting space 412 (Figure 10).

In this state, when the button 430 is pressed again, the piston 440 moves from the top to the bottom of the piston mounting space 412, and at this time, the piston elastic body 450 is compressed and communicates with the piston mounting space 412. The internal pressure of the disinfectant fluid flow space 413 increases (FIG. 11).

When the internal pressure of the disinfectant fluid flow space 413 increases, the second valve 470 mounted in the second valve mounting space 415 communicating with one side of the disinfectant fluid flow space 413 opens (the fifth protruding jaw). (425) opens the communication hole formed on the other side of the second valve mounting space 415), and the disinfectant solution (L) inside the disinfectant fluid flow space 413 flows into the second valve mounting space 415.

The disinfectant solution (L) flowing into the second valve mounting space 415 passes through the second valve mounting space 415 and the extraction needle 310 is inserted through the injection port 480 in communication with the second valve mounting space 415. It is sprayed into the first through hole 110.

In this way, by configuring the disinfection solution (L) to be sprayed into the first through hole 110, the inside of the first through hole 110 and the extraction needle 310 inserted into the first through hole 110 can be disinfected. do.

At this time, the extraction needle 310 may be inserted into the first through hole 110 so that the extraction hole 311 at the end faces the injection hole 480.

Meanwhile, the first main body 100 according to an embodiment of the present invention may be provided with a sterilizing unit (not shown) for sterilizing the inside of the through hole 110. In this case, the sterilizing unit may be provided with a UV lamp, etc. there is.

As described above, according to one embodiment of the present invention, the disposable sampling system 10 is provided with a first body 100 that couples to the container 20 and is detachably attached to the first body 100. By forming the second main body 200, the disposable sampling system 10 can be managed more easily.

In addition, the first main body 100 is provided with a disinfection unit 400 to disinfect the first main body 100 and the extraction unit 300, and the first main body and container coupled to the container 20 ( By significantly reducing the degree of contamination of the extraction unit 300 that extracts the biological reaction material in 20), there is an effect of preventing the biological reaction material extracted from the container 20 from being contaminated.

In addition, by equipping the first main body 100 with a disinfection unit 400 to disinfect the first main body 100 and the extraction unit 300, extraction of materials for biological reaction from the container 20 is possible. After performing the disinfection operation on the first main body 100 and the extraction unit 300, there is an effect in that the biological reaction material can be extracted from the container 20 once again after the disinfection operation.

In the above, even though all the components constituting the embodiment of the present invention have been described as being combined or operated in combination, the present invention is not necessarily limited to this embodiment. That is, as long as it is within the scope of the purpose of the present invention, all of the components may be operated by selectively combining one or more of them.

The above description is merely an illustrative explanation of the technical idea of the present invention, and various modifications and variations will be possible to those skilled in the art without departing from the essential characteristics of the present invention. Accordingly, the embodiments disclosed in the present invention are not intended to limit the technical idea of the present invention, but are for illustrative purposes, and the scope of the technical idea of the present invention is not limited by these embodiments. The scope of protection of the present invention should be interpreted in accordance with the claims below, and all technical ideas within the equivalent scope should be construed as being included in the scope of rights of the present invention.
