DESCRIPTION OF EMBODIMENTS OF DISCLOSURE

[0024] Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. Throughout this document, reference should be made to the drawings, in which the same reference numerals and symbols will be used to designate the same or like components. Additionally, in the following description of the present disclosure, detailed descriptions of known components and functions incorporated herein will be omitted in the case that the subject matter of the present disclosure may be rendered unclear thereby.

[0025] FIG. 1 is a conceptual view of an entire configuration of an apparatus for heating sample solution for ex vivo diagnosis according to an embodiment of the present disclosure, and FIG. 2 is a figure for illustrating a heating operation of an apparatus for heating sample solution for ex vivo diagnosis according to an embodiment of the present disclosure.

[0026] An apparatus for heating sample solution for ex vivo diagnosis according to an embodiment of the present disclosure relates to an apparatus of heating sample solution including biological sample or specimen for ex vivo diagnosis by a magnetic induction heating type, and comprises a reaction container (100), a case (200), a first induction coil (300), and a heating body (400).

[0027] The reaction container (100) is formed in a container shape to store sample solution (T). For example, the reaction container (100) is formed in a hollow cylinder shape having an opened upper side or portion, and a separate container cover (110) can be coupled to the opened side or portion of the reaction container (100). The reaction container (100) may be made of non-conductive and non-magnetic synthetic resins material.

[0028] The case (200) is a configuration forming a basic outer appearance of an entire apparatus, an accommodation space is formed in the case (200) to accommodate various components therein, and an insertion receptacle (or an insertion accommodation unit) 210 is formed at an upper surface of the case (200) so that the reaction container (100) is inserted to and accommodated in the insertion receptacle 210. In some exemplary embodiments, the plurality of the insertion receptacles (210) are formed, and the plurality of the reaction containers (100) are inserted to the plurality of the insertion receptacles (210), respectively, so that each of the reaction containers (100) can be independently heated, respectively.

[0029] The first induction coil (300) is disposed adjacent to the reaction container (200) in the case (200) and is configured to induce electromagnetic force when an alternating current is supplied.

[0030] The heating body (400) is inserted into an inner space of the reaction container (100) and is configured to induce a second current by the electromagnetic induction of the first induction coil (300) so that the heating body (400) can be heated by the induced second current.

[0031] Accordingly, the heating body (400) is inductively heated by the first induction coil (300), and therefore the heat of the heating body (400) is directly transferred to the sample solution (T) to heat the sample solution (T) so that heat transfer is performed without additional heat transfer medium and thus the sample solution (T) can be heated more quickly.

[0032] More specifically, the first induction coil (300) is arranged to be positioned below the rejection container (100) and inside the case (200), and is in a winding form having a spiral shape such that alternating power from an alternating power supplier (500) is supplied to the first induction coil (300). When the alternating current is supplied to the first induction coil (300), the direction of current flow is changed according to time flow, and therefore a magnetic field (M) is formed adjacent to the first induction coil (300) as illustrated in FIG. 2. At that time, the direction of magnetic field is changed at the same cycle as the cycle of changing the direction of the current flow of the first induction coil (300). The first induction coil (300) is arranged so that the magnetic field (M) can affect the heating body (400) inserted into the inside of the reaction container (100).

[0033] The heating body (400) may be formed in a capsule shape and be made of metal material having conductivity, and is inserted into and freely movable in the inside space of the reaction container (100). The heating body (400) induces the second current according to the change to the magnetic field formed by the first induction coil (300), and provides heat by the induced second current.

[0034] The exothermic reaction of the heating body (400) is an exothermic reaction of a magnetic induction type by the first induction coil, and the principle of this exothermic reaction is well known and therefore the detailed description thereof is omitted.

[0035] Meanwhile, the heating body (400) is made of material having conductivity for second current induction, and a second induction coil in a wound form is included in the heating body (400). For example, the second induction coil (not shown) can be formed to be wound around a core body (not shown) of non-conductive material (or conductive material) having a capsule shape formed lengthily in one direction.

[0036] A process of operation of an apparatus for heating sample solution according to the structure described above will be explained.

[0037] Firstly, sample solution (T) is poured into and stored in the reaction container (100), and in this state the reaction container (100) is inserted into the insertion receptacle (210) of the case (200). At that time, the heating body (400) is inserted into the inside of the reaction container (100), and the heating body (400) can be inserted any time before alternating current is supplied to the first induction coil (300). Accordingly, in a state that the heating body (400) is inserted and the reaction container (100) is inserted to the insertion receptacle (210) of the case (200), if the alternating power supplier (500) is activated by manipulation of an operation unit (not shown), alternating current is supplied to the first induction coil (300) and therefore magnetic field is generated as well as changed, second current is induced at the heating body (400) located in the reaction container (100) according to the change in the magnetic field of the first induction coil (300), and the heating body (400) is heated by the induced second current. Because the inductively heated heating body (400) is positioned in the sample solution (T) inside the reaction container (100), the heat of the heating body (400) can be directly transferred to the sample solution (T) thereby quickly heating the sample solution (T).

[0038] Accordingly, because an apparatus for heating sample solution for ex vivo diagnosis according to an embodiment of the present disclosure inductively heats the heating body (400), inserted to the inside of the reaction container (100), by the first induction coil (300), it can directly transfer the heat to the sample solution (T) using the heating body (400) without additional heat transfer medium instead of transferring heat through an additional heating block in a heat transfer and radiation type, and therefore the loss of heat can be minimized, through this the sample solution (T) can be quickly heated and diagnosis operation can be performed more quickly, and energy efficiency also can be improved.

[0039] Meanwhile, in certain exemplary embodiments, the plurality of the insertion receptacles (210) are formed at the case (200) so that the plurality of the reaction containers (100) can be inserted thereto, and in those embodiments, the first induction coil (300) is arranged below the lower portion of each of the insertion receptacles (210), in a case that a frequency of an alternating power supplied to each of the first induction coils (300) is formed differently to each other, the levels of the induced currents of the heating bodies (400) induced by the first induction coils (300) are different from each other, and because the heating temperature of the heating body (400) is different accordingly, the heating temperature of the sample solution (T) of each of the reaction containers (100) can be adjusted independently by this way. Therefore, more various ex vivo diagnosis can be performed by heating multiple sample solutions (T) at different temperatures simultaneously.

[0040] An apparatus for heating sample solution for ex vivo diagnosis according to another embodiment of the present disclosure can be configured to perform agitation function for sample solution so that reaction of diagnosis object material can be properly performed in sample solution in addition to heating function for sample solution.

[0041] The agitation function for sample solution can be performed by using the heating body (400), and an agitation structure for sample solution of an apparatus for heating sample solution for ex vivo diagnosis according to an embodiment of the present disclosure will be described below.

[0042] FIG. 3 is a figure for illustrating a mixing structure of an apparatus for heating sample solution for ex vivo diagnosis according to an embodiment of the present disclosure.

[0043] An apparatus for heating sample solution for ex vivo diagnosis according to an embodiment of the present disclosure is configured to rotatingly move the heating body (400) to agitate sample solution (T) stored in the reaction container (100), and for this a rotation driving unit (or a rotation driver) 600 configured to rotationally move the heating body (400) is included in the case (200).

[0044] At that time, as described above, the heating body (400) is made of metal material of conductive material, and, more specifically, the heating body (400) can be made of magnetic material, and the rotation driving unit (600) is configured to rotatingly move the heating body (400) by magnetic force from the outside of the reaction container (100).

[0045] Thus, the rotation driving unit (610) is configured to comprise a rotation magnet (610) rotatably mounted inside the case (200) to be positioned at the lower portion of the reaction container (100), and a driving motor (620) configured to rotate the rotation magnet (610), and is configured to rotatingly move the heating body (400) by the magnet force of the rotation magnet (610) according to the rotation of the rotation magnet (610). Here, the rotation magnet (610) is rotatable by being connected to a rotation axis of the driving motor (620), and the rotation magnet (610) can be formed such that permanent magnet is formed in a structure of being arranged at both sides with respect to the rotation axis.

[0046] These configurations of the rotation driving unit (600) are just exemplary embodiments, and various ways such as a type of using electromagnetic force instead of a type of using permanent magnet can be implemented.

[0047] According to these configurations, the heating body (400) inserted into the inside of the reaction container (100) can heat the sample solution (T) by being inductively heated by the first induction coil (300) as well as agitate the sample solution (T) by being rotated by the magnet force of the rotation driving unit (600).

[0048] Therefore, an apparatus for heating sample solution for ex vivo diagnosis according to an embodiment of the present disclosure can quickly heat the sample solution (T) and can perform agitation at the same time and accordingly ex vivo diagnosis can be performed more quickly and precisely.

[0049] The foregoing descriptions have been presented in order to explain certain principles of the present disclosure by way of example, and a person having ordinary skill in the art which the present disclosure relates could make various modifications and variations without departing from the essential features of the present disclosure. Accordingly, the foregoing embodiments disclosed in the present disclosure shall be interpreted as being illustrative, while not being limitative, of the principle and scope of the present disclosure. It should be understood that the scope of the present disclosure shall be defined by the Claims and all of their equivalents fall within the scope of the present disclosure.
