【発明の名称】多数の無作為に関連する血液試料を自動的選択的に処理する装置

Document Type and Number:

Japanese Patent JP3439475

Kind Code:

B2

Abstract:

An apparatus which provides an automatic, signal controlled, sample mixing/resuspending, aspiration and delivery system; wherein a demountable, rotatable carousel temporarily holds a multiplicity of sample containers. Electro-mechanical means, including optical sensors, is programmed to automatically move the carousel to a pre-selected position. A self centering vortexer/mixer lifts a selected sample container from the carousel, sealingly engages the sample container within a sample container support and thereafter orbitally mixes and resuspends the sample container contents. An aspiration probe enters the sample container through the support to receive the sample, which is forced out of the sample container by means of compressed air introduced into the sample container via the sample container support. The sample is delivered to an operably associated flow cytometer via the aspiration probe, after which the probe is washed and readied for the next cycle of operation.
