1 and 34, a modular fluid chip 1 (hereinafter referred to as a 'modular fluid chip 1') according to an embodiment of the present invention is formed in a module shape capable of performing one function. And connected with other modular fluid chips 2 to implement the fluid flow system 1000 of various structures.

The fluid flow system 1000 implemented through the modular fluid chip 1 may be used to collect a sample from a fluid, such as a liquid sample including body fluid, blood, saliva, skin cells, sample crush, gene or protein from the sample, etc. Amplification, antigen-antibody reactions, affinity chromatography and electrical sensing, electrochemical sensing, and capacitor type electricals using polymerase chain reaction including extraction, filtering, mixing, storage, valves, RT-PCR, etc. Analysis / detection processes, such as sensing, optical sensing with or without fluorescent materials, may be performed. However, the fluid flow system 1000 implemented through the modular fluid chip 1 is not necessarily limited to the above functions, and may perform various functions for fluid analysis and diagnosis. For example, in the present embodiment the modular

fluid chips

1, 2 are shown to perform a function for fluid movement, the fluid flow system 1000, for example, the fluid enters, the cells in the fluid is broken, After filtering, the gene may be amplified and configured to allow a series of processes to allow fluorescent material to be observed and observed in the amplified gene.

In addition, the fluid flow system 1000 implemented through the modular fluid chip 1 may implement Factory-on-a-chip technology through connection with another fluid flow system 1000. have. This allows not only to simultaneously perform fluid analysis and diagnosis on different fluids in each fluid flow system 1000, but also to perform all experiments related to fluids that can be performed using the fluid flow system 1000 (e.g., Chemical reactions, material synthesis, etc.) may be simultaneously performed through the plurality of fluid flow systems 1000.

In addition, the modular fluid chip 1 may be connected to the other modular fluid chip 2 in a horizontal direction (X-axis and Y-axis directions) to implement one fluid flow system 1000.

More specifically, the present modular fluid chip 1 is connected to another modular fluid chip 2 along the X and Y axis directions, which are shown in the horizontal direction in the drawing, and has a single fluid flow and analysis section. Fluid flow system 1000 may be implemented. Accordingly, the fluid can move freely in the X and Y axis directions. For example, the other modular fluid chip 2 may be connected in an amount of between 1 and 10,000 in the X and Y axis directions about the present modular fluid chip 1.

Modular fluid chip 1 according to various embodiments of the present invention will be described in more detail.

2 and 3, the modular fluid chip 1 according to the first embodiment of the present invention includes a body 11.

The body 11 is formed in the form of a module capable of performing one function and is accommodated inside the housing 12 and may be selectively replaced with the housing 12 as necessary. In addition, the body 11 may be formed in a shape corresponding to the inner surface of the housing 12 in which the accommodation space is formed, and may be formed at the same height as the housing 12 based on the Z axis direction of the drawing. For example, the body 11 may be manufactured using techniques such as MEMS, 3D printing, injection molding, CNC machining, imprinting, polymer casting, or the like.

In addition, when the body 11 is coupled to the housing 12, the body 11 may be fixed at a predetermined position and may be formed in a polyhedral structure so as to be in surface contact with the inner surface of the housing 12.

In addition, the body 11 may be formed to have a transparency or a part of the transparency so as to visually check the flow of the fluid flowing from the outside to the inside. For example, the body 11 may be formed of at least one of an amorphous material such as glass, wood, a polymer resin, a metal, and an elastomer, or a combination thereof.

In addition, part of the body 11 may be made of an elastomeric material.

For example, a portion in which the fluid flows or contacts with other parts of the body 11 may be formed of an elastomeric material. When the body 11 is partially formed of an elastomeric material, the body 11 may be manufactured through heterogeneous injection.

3 and 7, the body 11 is formed with a first hole 111 to guide the flow of the fluid.

The first hole 111 communicates with the second hole 121 of the housing 12, which will be described later, and the fluid channel 112, which will be described later, formed inside the body 11. To guide the flow of fluid in the direction of For example, the first hole 111 may be formed in a predetermined section from the outer surface of the body 11 toward the inside of the body 11, and may be formed in a section having a smaller size than the section in which the fluid channel 112 is formed.

In addition, the first hole 111 may be formed in a shape corresponding to the second hole 121 provided in the housing 12 and the fluid channel 112 provided in the body 11. Therefore, the first hole 111 may prevent a phenomenon in which the pressure of the fluid is increased or the flow of the fluid is unstable between the housing 12 and the body 11 during the flow of the fluid. For example, as illustrated in (a) of FIG. 8, the first hole 111 may have a circular cross section or may have a polygon or ellipse shape although not shown in the drawing. However, the shape of the first hole 111 is not limited thereto and may be formed in various shapes within a limit of 10 nm or more and 1 Cm or less.

Here, the first and

second holes

111 and 121 having a shape and size corresponding to each other to form a straight fluid path with each other have a predictable flow rate when the fluid is moved from one module to another module. To be able. Some conventional microfluidic flow devices transfer fluid through a tube. In the case of a device using a tube, there may be a difference in the width of the channel or a space in the channel at the portion where the tube and the device are connected to cause vortex in the fluid. These vortices not only cause a drastic change in flow velocity but can also change the shape of the droplets. Alternatively, physical impacts on the materials in the fluid or impede the movement of the materials. Thus, the arrangement of the first holes 111 of the body 11 and the second holes 121 of the housing 12 in the same width and in a straight line is not only a function of ensuring a connection between the modules, but also a stable flow velocity of the fluid. Enables stable movement of materials and materials In addition, the housing 12 and the second hole 121 of the housing 12 can ensure the stability of the above-described fluid no matter what function or shape the module in the module system of the present application.

In addition, the fluid channel 112 may be formed in the body 11.

3 and 7, the fluid channel 112 may be in communication with the at least one first hole 111 to enable flow of the fluid. For example, referring to FIG. 8C, the fluid channel 112 may have a polygonal cross section or may have a circular or elliptical shape although not shown in the drawing. However, the shape of the fluid channel 112 is not limited thereto, and the fluid channel 112 may be formed in various shapes within a limit of 10 nm or more and 1 Cm or less.

In addition, the fluid channel 112 may be configured to guide the flow of the fluid in various directions as well as to perform one preset function on the fluid in flow.

For example, referring to FIGS. 4 to 6, the inner side of the body 11 has a straight fluid channel 112 (FIGS. 4A and 4B) and a streamlined fluid channel 112 (FIG. 4C). (d), (e)), fluid channel 112 having at least one well ((f), (g), (h) of FIG. 4), fluid channel 112 having a valve ( (A), (b), (c), (d), and (e) of FIG. 5, the fluid channel 112 having at least one branch ((f), (g) of FIG. 5) , Cross-shaped fluid channel 112 (FIG. 5 (h), FIG. 6 (A)), Y-shaped fluid channel 112 (FIG. 6B), fluid channel with sensor (not shown) At least one of a fluid channel (not shown) having an electrical output unit and a fluid channel (not shown) having an optical output unit may be formed. However, the fluid channel 112 is not necessarily limited thereto, and may be changed and applied to various structures and shapes, and may be made through a combination of the aforementioned channels.

Meanwhile, another modular fluid chip 2 connected to the modular fluid chip 1 may have a body capable of performing a function different from one function of the body 11 of the modular fluid chip 1. 11) may be included.

That is, different types of fluid channels 112 may be formed in the body 11 of the modular fluid chip 1 and the body 11 of the other modular fluid chip 2.

Therefore, the plurality of modular fluid chips 1 connected to each other to implement the present fluid flow system 1000 may perform different functions with respect to the fluid flowing therein. Here, the plurality of modular fluid chips 1 connected to each other may be formed to perform only one function. For example, when one fluid chip 1 includes the Y-shaped fluid channel 112 to perform a function for mixing, the other fluid chip 1 connected thereto is the above-described Y-shaped fluid channel. Different types of

fluid channels

112 and 112 may be provided to perform other functions.

In addition, the modular fluid chip 1 according to the first embodiment of the present invention includes a housing 12.

3 and 7, the housing 12 is formed in a frame structure in which an accommodation space is formed, and is configured to accommodate the body 11 inside. In the housing 12, when the body 11 is accommodated in the accommodation space, the second hole 121 enables fluid to flow in correspondence with at least one first hole 111 provided in the body 11. ) Is formed.

The second hole 121 is formed at at least one position along the circumference of the housing 12, and communicates with the first hole 111 of the body 11 to fluid in at least one of an X-axis direction and a Y-axis direction. To guide the flow.

In addition, the second hole 121 is formed in a shape corresponding to the first hole 111 provided in the body 11 so that the pressure of the fluid increases between the housing 12 and the body 11 when the fluid flows. Unstable flow of fluid can be prevented. For example, as illustrated in FIG. 8B, the second hole 121 may have a circular cross section or may be formed in a polygon or ellipse shape although not shown in the drawing. However, the shape of the second hole 121 is not limited thereto, and the second hole 121 may be formed in various shapes within a limit of 10 nm or more and 1 Cm or less.

In addition, the housing 12 may be formed of at least one material of ceramic, metal, and polymer.
