Detailed Description

Hereinafter, the structure of the integrated cartridge of the present invention will be described with reference to the accompanying drawings.

Integrated box

Fig. 1 is a photograph showing the integrated box of the present invention.

As shown in fig. 1, the integrated cartridge 10 of the present invention may include a pre-processing part 100 for pre-processing a sample. The sample pretreated in the pretreatment section 100 may contain genetic material having nucleic acid. In the pretreatment section 100, a pretreatment operation required before eluting nucleic acid from a sample can be performed as follows.

Further, the integrated cartridge 10 may include an elution portion 200 that elutes effective components from the sample pretreated in the pretreatment portion 100. When the pre-treated sample contains nucleic acids, the elution portion 200 may elute the nucleic acids from the sample. That is, the active ingredient of the present invention may be a nucleic acid. However, the active ingredient of the present invention is not limited to nucleic acids. When the active ingredient is discharged from the elution unit 200, water may be discharged together with the active ingredient. Therefore, in the present specification, the active ingredient and water are defined as "fluid containing the active ingredient".

Further, the integrated cartridge 10 may further include a containing portion 300 containing the fluid containing the effective component eluted from the eluting portion 200. As described below, the containing portion may store a fluid containing an effective ingredient, and the effective ingredient stored in the containing portion may be amplified inside the containing portion to increase the amount of the effective ingredient. Here, as shown in fig. 1, the receiving part 300 may be disposed below the elution part 200. In this case, the fluid containing the effective component discharged from the elution portion 200 may fall vertically due to gravity or capillary force as will be described later, and thus be naturally supplied to the housing portion 300.

Referring again to fig. 1, the receiving part 300 may include a supply unit 310 that supplies the fluid containing the effective components discharged from the elution part 200. In particular, the supply unit 310 may be disposed below the elution portion 200. Therefore, the fluid containing the active ingredient discharged from the elution unit 200 may be vertically dropped by gravity or capillary force as described later, and supplied to the supply unit 310.

Further, the container part 300 may include a storage unit 320 storing and amplifying the fluid containing the effective ingredient supplied from the supply unit 310, and may further include an air discharge unit 330 discharging air existing inside the storage unit 320 to the outside. Hereinafter, the respective structures of the supply unit 310, the storage unit 320, and the air discharge unit 330 will be described in more detail.

Fig. 2 is a perspective view, a front view, a bottom view, and a side view showing a feeding unit of the unified cassette of the present invention.

As shown in fig. 2, a hole 312 may be defined in the supply unit 310. The holes 312 defined in the supply unit 310 may provide a path through which the fluid containing the effective ingredient discharged from the elution portion 200 moves. As shown in fig. 2, holes 312 defined in supply unit 310 may be defined from the top surface to the bottom surface of supply unit 310 so as to pass through the entire supply unit 310 in the thickness direction of supply unit 310.

Fig. 3 is a perspective view showing a storage unit of the unified cassette of the present invention, and fig. 4 is a sectional view taken along line a-a of fig. 3 showing the storage unit of the unified cassette of the present invention.

As shown in fig. 3 and 4, a pipe may be provided in the storage unit 320. An input hole 322a facing the hole 312 defined in the feed unit 310 may be defined in one end of the pipe 322 in the direction of the feed unit 310. The fluid containing the effective components may be supplied from the elution portion 200 into the tube 322 through the hole 312 of the supply unit 310 and the input hole 322a of the tube 322. That is, according to the present invention, when the hole 312 defined in the supply unit 310 and the input hole 322a of the tube 322 are matched with each other, the fluid containing the effective ingredient may be supplied into the tube 322.

Fig. 5 is a perspective view, a front view, a bottom view and a side view showing an air discharge unit of the integrated cassette of the present invention.

As shown in fig. 5, a hole 332 may also be defined in the air discharge unit 330. The hole 332 defined in the air discharge unit 330 may provide a path through which air existing inside the tube 322 of the storage unit 320 is discharged to the outside. As shown in fig. 4, the hole 332 defined in the air discharge unit 330 may be defined from the top surface to the bottom surface of the air discharge unit 330 to pass through the entire air discharge unit 330 in the thickness direction of the air discharge unit 330.

In addition, as shown in fig. 3 and 4, an output hole 322b may be defined in the other end of the pipe 322 in the direction of the air discharge unit 330, facing the hole 332 defined in the air discharge unit 330. Therefore, according to the present invention, when the hole 332 defined in the air discharge unit 330 and the output hole 322b of the duct 322 are matched with each other, the air existing in the duct 322 may be discharged to the outside through the air discharge unit 330. In particular, when the input hole 322a of the tube 322 is matched with the hole 312 of the supply unit 310 and the output hole 322b of the tube 322 is matched with the hole 332 of the air discharge unit 330, the fluid containing the effective components may be supplied into the tube 322 through the input hole 322a and the air inside the tube 322 is discharged to the outside through the output hole 322 b.

In addition, the tube 322 of the storage unit 320 of the present invention may have a very small diameter of 2mm or less. In this case, it is not sufficient to smoothly supply the fluid containing the active ingredient into the pipe 322 by using only the mechanical energy of the fluid containing the active ingredient. Therefore, according to the present invention, the fluid containing the effective ingredient can be transported in the tube 322 of the storage unit 320 by capillary force. The feature that "the fluid containing the active ingredient is transported in the tube by capillary force" should be interpreted to mean that the main force for transporting the fluid containing the active ingredient in the tube 322 is capillary force, and should not be interpreted to mean that the force for transporting the fluid containing the active ingredient in the tube 322 is only capillary force.

In order to transport the fluid containing the active ingredient in the tube 322 by capillary force, a coating layer made of a hydrophilic material for generating capillary force may be provided on the inner wall of the tube 322 of the storage unit 320. Therefore, the fluid containing the effective ingredient can be supplied into the tube 322 by the capillary force generated by the coating layer which is provided on the inner wall of the tube 322 and made of the hydrophilic material.

Similar to the tube 322, the fluid containing the active ingredient can be transported in the hole 312 of the supply unit 310 by capillary force. For this, a coating layer made of a hydrophilic material for generating a capillary force may be provided on the inner wall of the hole 312 of the supply unit 310.

It is preferable that the fluid containing the active ingredient is not discharged from the pipe 322 after the fluid containing the active ingredient is transferred to the pipe 322. This is done because, when the fluid containing the effective ingredient is discharged from the tube 322, the amplification efficiency of the effective ingredient may deteriorate during the subsequent amplification operation. That is, when the fluid containing the effective component is discharged from the tube 322, since the amount of the effective component contained in the tube 322 is reduced by the amount of the discharged effective component, the effective component may not be sufficiently reproduced during the subsequent amplification operation. Therefore, when the fluid containing the effective component is supplied to the pipe 322 through the input hole 322a, it is necessary to prevent the fluid containing the effective component from being discharged through the output hole 322 b.

For this, a coating layer made of a hydrophobic material for suppressing generation of capillary force may be provided on the inner wall of the hole 332 of the air discharge unit 330. Therefore, the efficiency of amplification of the active ingredient can be improved by preventing the fluid containing the active ingredient supplied to the tube 322 from being discharged through the output hole 322 b.

Also, as shown in fig. 2, one hole 312 may be defined in the supply unit 310, and as shown in fig. 3, a plurality of tubes 322 may be provided in the storage unit 320 (fig. 3 shows a configuration in which four tubes 322 are provided, thus defining four input holes 322a and four output holes 322 b).

Here, the supply unit 310 may be rotatable. That is, due to the rotation of the supply unit 310, the lower portion of the hole 312 of the supply unit 310 may sequentially match the input holes 322a of the plurality of tubes 322 provided in the storage unit 320. Also, as shown in fig. 2, a protrusion 314 protruding in a cross shape may be provided at a lower portion of the supply unit 310, and as shown in fig. 3, a coupling hole 324 having a through shape may be defined near the input hole 322a of the storage unit 320. In particular, a plurality of input holes 322a may be defined along the virtual circumference. In this case, the combining hole 324 adjacent to the input hole 322a may be defined at the center of a circle constituting an imaginary circumference. The protrusion 314 of the supply unit 310 may be coupled with the coupling hole 324 adjacent to the input hole 322 a. Therefore, according to the present invention, as the protrusion 314 coupled with the coupling hole 324 adjacent to the input hole 322a rotates, the lower portion of the hole 312 of the supply unit 310 may be sequentially matched with the input hole 322a, and as a result, the fluid containing the effective components may be sequentially supplied from the hole 312 of the supply unit 310 to the plurality of tubes 322.

On the other hand, when a plurality of tubes 322 are provided in the storage unit 320, a plurality of holes 332 may also be defined in the air discharge unit 330, as shown in fig. 5. In addition, the air discharge unit 330 may be rotatable. Also, as shown in fig. 5, a protrusion 314 protruding in a cross shape may be provided at a lower portion of the air discharge unit 330, and as shown in fig. 3, a coupling hole 324 having a through shape may be defined near the output hole 322b of the storage unit 320. In particular, a plurality of output apertures 322b may be defined along the virtual circumference. In this case, the coupling hole 324 adjacent to the output hole 322b may be defined at the center of a circle constituting the virtual circumference. The protrusion 314 of the air discharge unit 330 may be coupled to the coupling hole 324 adjacent to the output hole 322 b. Accordingly, as the protrusion 314 coupled to the coupling hole 324 adjacent to the output hole 322b rotates, the lower portion of the hole 332 of the air discharge unit 330 may be selectively matched with the output hole 322 b. As a result, it is possible to control by the rotation of the air discharge unit 330 according to circumstances such that a portion of the hole 332 of the air discharge unit 330 is matched with a portion of the output hole 322b of the air discharge unit 330, and the remaining portion of the hole 332 of the air discharge unit 330 is not matched with any of the output holes 322 b.

It has been described above that when the hole 332 of the air discharge unit 330 is matched with the output hole 322b of the duct 322, the air inside the duct 322 may be discharged to the outside. More preferably, as shown in fig. 3 and 5, the number of holes 332 defined in the air discharge unit 330 may be the same as the number of output holes 322b defined in the plurality of tubes 322.

As described above, a coating layer made of a hydrophobic material may be provided on the inner wall of the hole 332 of the air discharging unit 330 to prevent the fluid containing the effective components inside the tube 322 from being discharged through the output hole 322 b. However, although the fluid containing the effective components is prevented from being discharged through the output hole 322b, a portion of the fluid may exist in the hole 332 of the exhaust unit 330 through the output hole 322 b. Here, if only one hole 332 is provided in the air discharge unit 330, the hole 332 of the air discharge unit 330 is sequentially matched with the plurality of output holes 322b during the rotation of the air discharge unit 330. In this case, cross-contamination may occur in which the effective components introduced into each tube 322 are introduced into the other tubes 322.

In order to solve problems such as cross-contamination, the number of the holes 332 defined in the air discharge unit 330 may be the same as the number of the output holes 322b defined in the plurality of tubes 322. In this case, the holes 332 defined in the air discharge unit 330 may correspond one-to-one to the output holes 322b defined in the plurality of tubes 322 to prevent cross contamination from occurring.

Although the present invention has been described above by way of the detailed description and the accompanying drawings, the present invention is not limited thereto, and it is apparent that various changes and modifications can be made by one of ordinary skill in the art within the technical spirit of the present invention and the equivalent scope of the appended claims.
