Description
본 발명은 검체 채취가 용이한 효과를 갖는 코로나 바이러스 감염 진단을 위한 검체 채취용 조성물 및 이를 이용한 코로나 바이러스 감염 진단 키트에 관한 것이다.The present invention relates to a sample collection composition for diagnosing corona virus infection having an effect of easy sample collection and a coronavirus infection diagnosis kit using the same.
코로나19(COVID-19, severe acute respiratory syndrome coronavirus 2(SARS-CoV-2))는 외피가 있는 양성가닥 RNA 바이러스(non-segmented positive-strand RNA virus)로서 전염성이 높고 병원성인 것으로 보고되어 감염된 환자에게 심각한 폐렴 증상을 유발한다. COVID-19 (severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)) is an enveloped, non-segmented positive-strand RNA virus that has been reported to be highly contagious and pathogenic to infected patients. cause severe pneumonia.
계통 분석 결과 SARS-관련 코로나바이러스와 가장 가까운 것으로 확인되었다. 코로나19의 명칭은 감염병을 나타내는 것으로, severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)는 바이러스 이름을 나타내는 것으로 각각 분리되어 명명되었다.Phylogenetic analysis identified it as closest to SARS-associated coronaviruses. The name of Corona 19 represents an infectious disease, and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) represents the name of the virus, respectively.
코로나19는 감염자의 비말이 호흡기나 눈, 코, 입의 점막으로 침투될 때 전염되는 것으로 알려져 있으며, 특히, 노인 및/또는 심혈관 질환, 당뇨병, 만성 호흡기 질환 및 암과 같은 기저 질환을 가진 사람들에게 생명을 위협할 수 있는 것으로 알려져 있다.COVID-19 is known to be transmitted when droplets from an infected person penetrate the respiratory tract or mucous membranes of the eyes, nose, or mouth, especially in the elderly and/or those with underlying diseases such as cardiovascular disease, diabetes, chronic respiratory disease, and cancer. It is known to be life threatening.
더욱이, 최근 다양한 변이가 속출하며, 감염 속도와 확산 범위 측면에서 기존의 다른 코로나 바이러스과 대비하여 특이점을 가진다. 이는 다른 코로나 바이러스에 비해 잠복기가 14일로 긴 편이어서, 감염되었으나 무증상인 상태에서 다른 사람에게 감염원을 옮길 수 있는 가능성이 높기 때문이다.Moreover, various mutations have recently appeared one after another, and it has a peculiarity compared to other existing coronaviruses in terms of infection rate and spread range. This is because it has a longer incubation period of 14 days than other coronaviruses, so there is a high possibility that it can spread the source of infection to others while being infected but asymptomatic.
SARS-CoV-2는 5 가지 주요 단백질 영역으로서 ORF1ab(replicase complex), 스파이크, 인벨로프, 막 및 뉴클레오캡시드 단백질을 가지고 있다. SARS-CoV-2의 감염 진단을 위한 방법으로는, PCR 검사, 신속 항원 검사 등이 있으며, 간편하고, 대량 검사가 가능하며, 비교적 즉각적인 감염 여부를 확인할 수 있는 신속 항원 검사가 널리 활용되고 있다.SARS-CoV-2 has five major protein regions: ORF1ab (replicase complex), spike, envelope, membrane and nucleocapsid proteins. As methods for diagnosing SARS-CoV-2 infection, there are PCR tests, rapid antigen tests, etc., and rapid antigen tests are widely used because they are simple, mass-testable, and can confirm relatively immediate infection.
신속 항원 검사는 대상의 콧구멍을 통해 검체 채취 면봉으로 비인두에서 분비물을 긁어 검체를 채취함에 따라, 검체의 채취 과정에서 대상(검사 대상자)으로 하여금 불쾌감과 통증을 유발하는 문제가 있어, 신속한 검사법임에도 불구하고, 꺼려지는 검사방법의 하나로 인식되고 있다.The rapid antigen test collects a sample by scraping secretions from the nasopharynx with a sample collection swab through the nostrils of the subject, causing discomfort and pain to the subject (test subject) during the sample collection process. Despite this, it is recognized as one of the reluctant inspection methods.
비인두에서 검체의 채취 시 분비물을 긁어낼 필요 없이, 가볍게 접촉하는 것만으로 검체를 채취할 수 있도록 하여 검사를 보다 원활히 수행할 수 있는 기술에 대한 개발이 필요한 실정이다.When collecting a sample from the nasopharynx, there is a need to develop a technology that can more smoothly perform the test by allowing the sample to be collected only by lightly touching it without the need to scrape secretions.
비인두에 가볍게 접촉하여도 코로나 바이러스 진단을 위한 검체의 채취가 가능하여 검체 채취 시의 불쾌감과 불편함을 완화시킬 수 있는 코로나 바이러스 감염 진단을 위한 검체 채취용 조성물을 제공하는 것을 목적으로 한다.It is an object of the present invention to provide a composition for collecting samples for diagnosing coronavirus infection that can relieve discomfort and discomfort during sample collection by allowing samples to be collected for diagnosis of coronavirus even when lightly contacted with the nasopharynx.
본 발명은 또한, 검체의 고정력이 우수한 한편, 추출 버퍼에 넣으면 코로나 바이러스의 추출이 용이하여, 민감도와 특이도가 우수한 효과를 갖는 코로나 바이러스 감염 진단 키트를 제공하는 것을 목적으로 한다.Another object of the present invention is to provide a diagnostic kit for corona virus infection, which has excellent fixation power of a sample, easy extraction of coronavirus when put in an extraction buffer, and excellent sensitivity and specificity.
상기와 같은 과제를 해결하기 위한, 본 발명에 따른 검체 채취용 조성물은, 검사 대상자의 비인두로부터 검체를 채취하는 검체 채취 면봉 검체로부터 코로나바이러스를 추출하기 위한 추출 버퍼가 담긴 추출용 용기 상기 추출 버퍼에 상기 검체 채취 면봉을 침지시켜 얻어진 검출액을 적가하는 검출액 투입부와 코로나 바이러스의 감염 여부를 시각적으로 나타내는 식별부를 구비한 진단 본체를 포함하는, 코로나 바이러스(SARS-CoV-2) 감염 진단 키트에 사용되는 검체 채취용 조성물로서, 생리 식염수 100 중량부, 폴리메틸메타크릴레이트(Polymethylmethacrylate, PMMA) 20 내지 30 중량부, 히알루론산 10 내지 15 중량부 및 펙틴 5 내지 7 중량부를 포함하는 코로나 바이러스 감염 진단 키트에 사용되는 검체 채취용 조성물에 관한 것이다.In order to solve the above problems, the composition for sampling according to the present invention is an extraction container containing an extraction buffer for extracting coronavirus from a specimen collection swab specimen that collects a specimen from the nasopharynx of a test subject. The extraction buffer A coronavirus (SARS-CoV-2) infection diagnosis kit comprising a diagnosis main body having a detection liquid injection unit for dropwise addition of a detection liquid obtained by immersing the sample collection swab in and an identification unit that visually indicates whether or not coronavirus is infected. As a sample collection composition used for corona virus infection, including 100 parts by weight of physiological saline, 20 to 30 parts by weight of polymethylmethacrylate (PMMA), 10 to 15 parts by weight of hyaluronic acid, and 5 to 7 parts by weight of pectin It relates to a composition for sampling used in a diagnostic kit.
본 발명에 있어서, 상기 생리 식염수는 의료기기에 사용될 수 있는 것을 사용하는 것이 바람직하고, 이에 관해서는, 관련 기술분야의 기술을 참고할 수 있다.In the present invention, it is preferable to use the physiological saline solution that can be used in medical devices, and in this regard, reference may be made to techniques in the related art.
상기 폴리메틸메타크릴레이트는 분말 형태로 계량되어 첨가되며, 상기 생리 식염수 100 중량부를 기준으로 20 내지 30 중량부, 보다 바람직하게는, 22 내지 25 중량부로 첨가될 수 있다.The polymethylmethacrylate is metered and added in powder form, and may be added in an amount of 20 to 30 parts by weight, more preferably 22 to 25 parts by weight, based on 100 parts by weight of the physiological saline solution.
상기 함량보다 과다하게 첨가되는 경우에는, 검체 채취 면봉에 코팅할 때, 얇은 두께로 코팅하기 어려운 문제가 있고, 헤드부의 질감이 저하되어 비인두에 접촉 시 검사 대상자로 하여금 불편함과 비인두 통증을 유발할 수 있는 문제가 있다.If it is added in excess of the above content, there is a problem that it is difficult to coat the sample collection swab with a thin thickness, and the texture of the head part is deteriorated, causing discomfort and nasopharyngeal pain to the test subject when in contact with the nasopharynx. There are problems that can cause it.
상기 함량보다 소량으로 첨가되는 경우에는, 검체 채취 면봉에 코팅은 가능하나, 검체와의 결합력이 낮아, 가벼운 접촉 만으로는 검체의 채취가 어려운 문제가 있어, 일반 시판 신속 항원 검사 키트에 포함된 검체 채취 면봉과 대비하여 효과 차이가 현저하지 않은 문제가 있다.When added in a smaller amount than the above, it is possible to coat the sample collection swab, but the binding force with the sample is low, making it difficult to collect the sample with only light contact. There is a problem that the difference in effect is not remarkable in comparison with
한편, 상기 히알루론산은 10 내지 15 중량부로 첨가될 수 있고, 보다 바람직하게는, 11 내지 14 중량부로 첨가될 수 있다. On the other hand, the hyaluronic acid may be added in 10 to 15 parts by weight, more preferably, 11 to 14 parts by weight.
상기 함량보다 과다한 경우에는, 친수성 용액에서 쉽게 코팅이 벗겨지는 등의 품질 안정성에 문제가 있을 수 있다.If the content exceeds the above, there may be problems with quality stability, such as easy peeling off of the coating in a hydrophilic solution.
상기 함량보다 소량으로 첨가되는 경우에는, 검체와의 결합력 향상 효과가 미미하여, 가벼운 접촉으로 검체의 채취가 어려운 문제가 있다.When added in a smaller amount than the above content, the effect of improving the binding force with the sample is insignificant, and thus, there is a problem in that it is difficult to collect the sample by light contact.
상기 히알루론산은 분자량이 50,000 내지 70,000 Da인 것을 사용할 수 있는데, 상기 분자량보다 큰 경우에는, 점도의 증가로 조성물을 제조하더라도 얇은 두께로 코팅하기 어려운 문제가 있고, 상기 분자량보다 작은 경우에는, 친수성의 저하로 인하여, 검체와의 결합력이 저하되는 문제가 있다.The hyaluronic acid may have a molecular weight of 50,000 to 70,000 Da. If the molecular weight is greater than the molecular weight, it is difficult to coat the composition with a thin thickness even if the composition is prepared due to an increase in viscosity. Due to the decrease, there is a problem that the binding force with the specimen is reduced.
상기 펙틴은 5 내지 7 중량부로 포함될 수 있으며, 상기 함량보다 과량으로 첨가되는 경우에는, 점도의 증가로 인하여 스프레이 코팅방법으로 검체 채취 면봉을 코팅하기 어려워지는 문제가 있고, 상기 함량보다 소량으로 첨가되는 경우에는, 검체와의 결합력이 저하되는 문제가 있다.The pectin may be included in 5 to 7 parts by weight, and when added in excess of the above content, there is a problem in that it is difficult to coat the sample collection swab by the spray coating method due to the increase in viscosity, and added in a smaller amount than the above content In this case, there is a problem in that the binding force with the specimen is lowered.
