Description

필터 피펫 팁{Filter Pipette Tip}Filter Pipette Tip

본 고안은 필터 피펫 팁(Filter Pipette Tip)에 관한 것으로서, 보다 상세하게는 피펫 팁(10)에 필터(Filter)(30)를장착시켜 검체나 시료의 교차로 인한 오염(Contamination)의 오류를 제거 하고자 한 고안에 관한 것이다.The present invention relates to a filter pipette tip, and more particularly, to remove the error of contamination due to the intersection of a sample or a sample by mounting a filter 30 on the pipette tip 10. It is about one design.

일반적으로, 피펫으로 검체(Specimen)나 시료를 검사 및 분석 시 일회용인 피펫 팁(10)을 이용하여 분석 장비(수동 또는 자동)에 이송시켜 검사 및 분석을 실시하는데 장비의 진동이나 관리상의 소홀로 인하여 검체나 시료가 팁 Holder(20) 끝 부분에 오염(Contamination) 되어, 또 다른 검체 또는 시료의 검사나 분석 시 계속적인 오류의 결과를 초래하며 특히 검체의 검사에 있어서는 위양성을 나타내는 폐단이 있다.In general, when a specimen or a sample is examined and analyzed by a pipette, the pipette tip 10 for single use is used to transfer to an analytical device (manual or automatic) for inspection and analysis. As a result, the sample or the sample is contaminated at the tip of the tip holder 20, resulting in a continuous error when inspecting or analyzing another sample or sample.

특히 자동분석기의 경우 팁 Holder(20)의 오염으로 반복적인 오류의 재현성을 가져올 수 있으며, 특히 검사방법 중에 Pooling Method에 의한 검사나 분석에 있어서 팁 Holder(20)의 오염 그 자체는 위양성에 대한 확인검사(Conform Test)의 증가는 물론 심지어 전량(全量) 전수검사 (全數 檢査)를 재실시 하여야 하는 심적 시간적 경제적인 손실은 매우 크다 하겠다.In particular, in the case of the automatic analyzer, the contamination of the tip holder 20 may bring about reproducibility of repetitive errors.In particular, in the inspection or analysis by the pooling method during the inspection method, the contamination of the tip holder 20 itself is confirmed as false positive. In addition to the increase in the Conform Test, the mental and time-related economic losses of having to re-perform the entire inspection are very large.

본 고안의 목적은 피펫 팁 Holder(20)의 끝부분에 오염(Contamination)을 방지하고 정확한 검사나 분석이 가능하도록 피펫 팁(10) 끝부분에 소수성(疏水性)(Resists water, oils, organic solvent)의 기능 즉 공기(Air)는 통과시키고 액체(Water, Organic solvents)는 투과 시키지 못하는 필터(30)를 장착하여 피펫 팁 Holder(20) 오염을 원천적으로 방지한다.The purpose of the present invention is to prevent contamination at the end of the pipette tip holder 20, and to ensure accurate inspection or analysis, hydrophobic (Resists water, oils, organic solvent) at the end of the pipette tip 10. ) Function, that is, air (Air) passes through and the liquid (Water, Organic solvents) through the filter 30 is mounted to prevent the pipette tip holder (20) contamination.

필터(30)의 구멍의 크기(Pore size)는 0.2um으로서 피펫 팁(10) 내벽에 도 3과 같이 필터(Filter)(30)를 접착 고정 시켜 (A) 부분과 (B) 부분을 밀폐시킨다.The pore size of the filter 30 is 0.2um and the filter 30 is adhesively fixed to the inner wall of the pipette tip 10 to seal the (A) and (B) parts as shown in FIG. 3. .

이하 상기한 목적을 달성하기 위한 바람직한 본 고안의 실시 예를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings an embodiment of the present invention for achieving the above object is as follows.

도 1 내지는 도 3에서 도시한 바와 같이 상기의 도3의 필터 피펫 팁(Filter Pipette Tip)은 도 2의 기존의 피펫 팁(10) 끝 부분에 소수성(疏水性)(Resists water, oils, organic solvent)의 기능 즉 공기(Air)는 통과시키고 액체(Water, Organic solvents)는 투과 시키지 못하는 필터(30)가 접착되어 있으며 필터(30)를 기준으로 (A) 공간과 (B) 공간은 밀폐 되어 있다.As shown in FIGS. 1 to 3, the filter pipette tip of FIG. 3 is hydrophobic (Resists water, oils, organic solvent) at the end of the conventional pipette tip 10 of FIG. 2. ), That is, air 30 is allowed to pass through and water (organic solvents) are not allowed to pass through. The filter 30 is bonded and the (A) and (B) spaces are sealed based on the filter 30. .

도 3의 피펫 팁(10)의 끝부분에 장착된 필터(30)는 피펫 팁 Holder(20)와 공간을 마련하여 접촉이 되지 않도록 하여야 한다.The filter 30 mounted at the end of the pipette tip 10 of FIG. 3 should have a space with the pipette tip holder 20 so as to prevent contact with the pipette tip holder 20.

이상에서와 같이 본 고안에 의하면, 피펫 팁 Holder(20)가 검체나 시료로부터 오염되는 것을 사전에 원천적으로 차단하며, 피펫 팁 Holder(20)의 오염으로 인하여 야기되는 위양성에 대한 확인검사(Conform Test)의 증가는 물론 심지어 전량(全量) 전수검사 (全數 檢査)의 재실시 등 시간적 경제적인 손실을 방지하며, 검사자로 하여금 검체나 시료의 교차 오염에 대한 심리적인 안정감을 도모할 수 있다As described above, according to the present invention, the pipette tip holder 20 prevents the contamination from the sample or the sample in advance, and checks the false positives caused by the contamination of the pipette tip holder 20 (Conform Test). ), And even prevents time and economic losses such as re-execution of the entire inspection, and allows the inspector to improve the psychological stability of the cross-contamination of the sample or sample.
