Definitions
- the present invention relates to a sample collection container.
- a sample collection container in which the inside of a blood collection tube or the like is decompressed is widely used (for example, Patent Document 1).
- the sample collection container is designed so that a specified amount of sample can be collected by reducing the pressure inside.
- a sample collection container may be used in which the inside is decompressed and a liquid for mixing with the sample is stored in advance.
- the sample collection container is designed so that the sample to be collected and the contained liquid are mixed at a predetermined mixing ratio.
- Examples of the sample collection container include a vacuum collection tube containing a liquid containing an anticoagulant.
- the internal pressure of the sample collection container gradually increases, and the contained liquid gradually evaporates.
- the mixing ratio of the sample to be collected and the contained liquid may change as time passes after production.
- the change in the mixing ratio can be suppressed to some extent by packing the sample collection container in an aluminum gusset bag, the effect is not sufficient. Further, this method has a problem that waste increases.
- An object of the present invention is to provide a sample collection container capable of suppressing a change in the mixing ratio of a sample to be collected and a contained liquid even when a long period of time has passed since the production. ..
- a sample collection container from which a sample is collected, the container body having an opening, a plug attached to the opening, and arranged on the outer surface of the container body.
- a sample having a barrier film and a liquid contained in the container body, and the water vapor permeability of the barrier film at 40 ° C. and 90% RH is 0.8 g / (m 2 ⁇ day) or less.
- a collection container is provided.
- the air permeability of the sample collection container at 40 ° C. and 0% RH is 0.5 cc / (m 2 ⁇ day ⁇ atm) or less.
- the water vapor transmission rate of the sample collection container at 40 ° C. and 0% RH is 1.1 g / (m 2 ⁇ day) or less.
- the barrier film is arranged in the circumferential direction of the outer surface of the container body in 0.2 laps or more and 3 laps or less.
- the surface area of the portion where the barrier film is arranged is 15% or more and 90% or less of the total surface area of the outer surface of the container body.
- the thickness of the barrier film before being placed on the outer surface of the container body is 5 ⁇ m or more and 300 ⁇ m or less.
- the barrier film has a first film, a first adhesive layer, a second film, and a second adhesive layer in this order.
- the second adhesive layer is arranged on the outer surface of the container body.
- the first film is the barrier film body
- the second film is the polyethylene terephthalate film.
- the material of the container body is polyethylene terephthalate or polyethylene naphthalate.
- the sample is blood and the liquid is a liquid containing an anticoagulant.
- the anticoagulant is citric acid, EDTA, or heparin.
- the amount of the liquid contained in the container body is 0.1 mL or more and 5 mL or less.
- the sample collection container according to the present invention is a sample collection container from which a sample is collected, and is arranged on a container body having an opening, a plug attached to the opening, and an outer surface of the container body.
- the barrier film and the liquid contained in the container body are provided, and the water vapor permeability of the barrier film at 40 ° C. and 90% RH is 0.8 g / (m 2 ⁇ day) or less. Since the sample collection container according to the present invention has the above configuration, the change in the mixing ratio between the sample to be collected and the contained liquid can be changed even when a long period of time has passed since the production. It can be suppressed.
- FIG. 1 is a front sectional view schematically showing a sample collection container according to the first embodiment of the present invention.

(1)検体採取容器の空気透過度(40℃及び0%RH)
得られた検体採取容器を40℃及び0%RHの恒温恒湿装置内に保管した。検体採取容器内に水を吸引採取し、採取量と内圧との検量線から、保管による内圧の増加量を求め、空気透過度を計算した。なお、比較例2では、アルミガゼット袋内に収容された状態で検体採取容器を恒温恒湿装置内に保管して、上記の操作を行った。
各実施例及び各比較例で用いた容器本体とバリアフィルムとの組み合わせにおいて、内部に液体が収容されていない容器本体内に水を収容し、栓体により密閉して、容器本体の外表面上にバリアフィルムが配置された検体採取容器(内部が減圧されておらず、かつ内部に水が収容された検体採取容器)を得た。得られた検体採取容器を40℃及び0%RHの恒温恒湿装置内に保管した。保管前後の検体採取容器の重量の減衰量を水の蒸散量として、水蒸気透過度を計算した。なお、比較例2では、アルミガゼット袋内に収容された状態で検体採取容器を恒温恒湿装置内に保管して、上記の操作を行った。
得られた検体採取容器を、40℃及び0%RHの恒温恒湿装置内に70日間保管した。40℃及び70日間の保管は、25℃及び1年間の保管に相当する。なお、比較例2では、アルミガゼット袋内に収容された状態で検体採取容器を恒温恒湿装置内に保管した。
製造直後及び保管後の検体採取容器に収容された液体量を測定した。
採血針を用いて、製造直後及び保管後の検体採取容器に血液を採取した。採取された血液量を測定した。
上記(3-1)及び(3-2)で測定した液体量と検体量とから、製造直後及び保管後の検体採取容器での液体と検体との混合比を、下記式(1)により算出した。また、算出した混合比から、混合比の変化割合を下記式(2)により算出した。
混合比の変化割合(%)=(Y-X)/X×100 ・・・(2)
X:製造直後の検体採取容器での混合比
Y:保管後の検体採取容器での混合比
1a…外表面
2…栓体
3,3A…バリアフィルム
4…液体
11,11A…検体採取容器
31…第1のフィルム
