Abstract:
A purpose of the present invention is to provide a device which enables to collect a very small amount of a sample in a state suitable for later examination, without using an absorbent or a chemical solution, even when a very small amount of a sample is collected. A further purpose is to provide a device which enables to collect blood suitable for later blood examination, even when the sample is a very small amount of peripheral blood instead of brachial vein blood. Yet a further purpose is to provide a very small sample collection and separation device for use in measuring a very small amount of peripheral blood sample with good accuracy using a conventional reagent and analytical apparatus. Provided is a sample collection and separation device comprising a sample collection unit having a sample collection portion that uses capillary action and an analyte storage unit having a housing into which the sample collection unit is inserted, whereby the sample collection unit containing the collected sample is integrated by means of insertion, so as to permit centrifugation and storage or transport of the sample, and the target sample can be recovered following centrifugation.

Claim (Index 8):
A sample collection and separation device, comprising:\n a sample collection unit having an inside space for holding a sample and having openings at the top and the bottom, wherein the inside space, the bottom opening and the top opening communicate, the inner diameter thereof increases from the bottom opening toward the top opening, and the wall surface defining the inside space into which a sample is placed forms a gradient continuing from the bottom opening toward the top opening; an analyte storage unit having a housing into which the sample collection unit is inserted and having a sample collection unit bottom cap tightly sealing the bottom opening of the sample collection unit, wherein the sample collection unit bottom cap has an agent holding portion for holding an agent, and it is configured that when the sample collection unit is inserted into the analyte storage unit and the bottom opening is inserted into the agent holding portion, then, at least a part of the agent enters into the sample collection unit; and an analyte sealing cap for plugging the top opening of the sample collection unit, wherein when the analyte sealing cap plugs the top opening under condition of insertion of the sample collection unit into the analyte storage unit, the sample is sealed.
