이동식 버튼과 흡습지 체결을 통한 측방유동분석 액체 흡입장치{Liquid Suction Device for Lateral Flow Assay Using Movable Button with Absorbent Paper}Liquid Suction Device for Lateral Flow Assay Using Movable Button with Absorbent Paper}

본 발명은 이동식 버튼과 흡습지를 체결을 통한 측방유동분석 액체 흡입장치에 관한 것으로, 더욱 상세하게는 흡습지를 체결한 이동식 버튼을 슬라이딩을 통해 센서 표면의 용액 흡수를 조절할 수 있는 측방유동분석 액체 흡입장치에 관한 것이다.The present invention relates to a lateral flow analysis liquid suction device by fastening a movable button and a absorbent paper, and more particularly, to a lateral flow analysis liquid suction device capable of controlling solution absorption on a sensor surface by sliding a movable button fastened to a absorbent paper. It is about.

측방유동분석(lateral flow assay; LFA)은 간단한 현장 진단법 중 하나이다. 이에 단백질, 항생제, 유독 물질 등을 검출하기 위한 방법으로 응용되어 왔다. Lateral flow assay (LFA) is one of the simple point-of-care diagnostic methods. Accordingly, it has been applied as a method for detecting proteins, antibiotics, and toxic substances.

이러한, LFA는 특이적으로 결합할 수 있는 생물학적 또는 화학적 물질을 나이트로셀룰로오스 멤브레인(Nitrocellulose membrane)에 미리 고정시킴으로써, 액체 시료가 모세관 현상에 의해 흘러가면서 테스트와 컨트롤 라인(Control line)에 검출 신호를 형성하여 목표 물질을 검출하는 방법으로 알려져 있다.These LFAs pre-immobilize biological or chemical substances that can specifically bind to a nitrocellulose membrane, so that the liquid sample flows by capillary action and transmits a detection signal to the test and control lines. It is known as a method of forming and detecting a target substance.

그러나, 기존 LFA는 용액이 멤브레인을 따라 모세관력에 의하여 스스로 이동하므로 추가적인 펌프 및 밸브 등과 같은 장치 없이 이용가능한 장점이 있지만, 용액 제어가 힘들기 때문에 반응시간 조절 및 잔여물 제거 등에 제한적이며, 이로 인해 민감도가 낮은 문제점이 있다. However, the existing LFA has the advantage of being usable without additional pumps and valves as the solution moves along the membrane by itself by capillary force, but it is difficult to control the solution, so it is limited to control the reaction time and remove residues. There is a problem of low sensitivity.

상기와 같은 문제점을 해결하기 위한 본 발명의 목적은 용액 제어를 통하여 LFA의 짧은 반응시간을 길게 만들어 주거나, 센서 표면에 존재하는 잔여물을 효과적으로 제거함으로써 센서 민감도를 증가시킬 수 있는 이동식 버튼과 흡습지를 체결을 통한 측방유동분석 액체 흡입장치를 제공하는 데 있다. An object of the present invention to solve the above problems is to increase the sensitivity of the sensor by making the short reaction time of LFA longer through solution control or by effectively removing residues present on the sensor surface. It is to provide a lateral flow analysis liquid suction device through fastening.

상기와 같은 목적을 달성하기 위한 본 발명의 이동식 버튼과 흡습지를 체결을 통한 측방유동분석 액체 흡입장치는 LFA에 적용하기 위한 버퍼, 혈액, 용액을 투입하는 투입구와 이동식 버튼을 수동으로 슬라이딩할 수 있도록 형성한 홈을 포함하는 상판; 상기 상판과 결합하여 기판을 지지하는 하판; 상기 상판과 하판 사이에 위치하며, 상면 일측에 버퍼, 혈액, 용액을 분석하기 위한 전기화학센서를 포함하는 기판; 및 상기 상판의 홈을 따라 슬라이딩되는 이동식 버튼;을 포함하는 것을 특징으로 한다.In order to achieve the above object, the lateral flow analysis liquid suction device by fastening the movable button and the absorbent paper of the present invention is to manually slide the inlet and movable button for injecting buffer, blood, and solution for application to LFA A top plate containing a formed groove; a lower plate coupled to the upper plate to support a substrate; a substrate positioned between the upper and lower plates and including an electrochemical sensor for analyzing a buffer, blood, and solution on one side of the upper surface; and a movable button sliding along the groove of the top plate.

상기 전기화학센서는 기판 자체에 일체화되는 것을 특징으로 한다.The electrochemical sensor is characterized in that it is integrated into the substrate itself.

상기 이동식 버튼의 하면에는 버퍼, 혈액, 용액을 흡습하는 흡습지가 체결되어, 상기 상판의 홈을 따라 이동식 버튼을 슬라이딩함으로써 전기화학센서 표면의 버퍼, 혈액, 용액을 흡습하는 것을 특징으로 한다.An absorbent paper for absorbing buffer, blood, and solution is fastened to the lower surface of the movable button, and the buffer, blood, and solution on the surface of the electrochemical sensor are absorbed by sliding the movable button along the groove of the top plate.

상기 이동식 버튼의 하면에 체결된 흡습지를 상판의 홈을 따라 슬라이딩을 조절하여 전기화학센서 표면의 버퍼, 혈액, 용액 흡수를 조절하는 것을 특징으로 한다.It is characterized in that the absorption of buffer, blood, and solution on the surface of the electrochemical sensor is controlled by adjusting the sliding of the absorbent paper fastened to the lower surface of the movable button along the groove of the upper plate.

이상과 같이, 본 발명에 따르면 흡습지와 이동 가능한 버튼의 체결을 통하여 기존 LFA의 상시 흡습 기능을 개선하여 센서 표면 용액의 흡습 유무의 능동적 조절이 가능하다.
