Abstract

Provided is a blood collection apparatus with which blood can be stably collected from a finger tip of any subject while ensuring safety and ease. This blood collection apparatus is provided with: a puncture site holding mechanism for holding a puncture site; a compression mechanism for performing an operation of compressing and releasing the puncture site when blood is collected from the puncture site; a container holding mechanism for holding a container for collecting blood flowing from a puncture wound at the puncture site; and a driving mechanism for varying the relative distance between the puncture site and the container by vertically moving the puncture site holding mechanism, the container holding mechanism, or the container held by the container holding mechanism when blood flowing from the puncture wound is collected.

Dependent claims

A blood collection apparatus comprising:

a puncture site holding mechanism for holding a puncture site of a subject;
a compression mechanism for performing an operation of compressing and releasing the puncture site when the blood is collected from the puncture site;
a container holding mechanism for holding a container for collecting blood flowing from a puncture wound at the puncture site;
and
a driving mechanism configured to:
vary a relative distance between the puncture site and the container by vertically moving the puncture site holding mechanism, the container holding mechanism, or the container held by the container holding mechanism while the compression mechanism performs the operation of compressing and releasing the puncture site, and
repeatedly vary the relative distance between the puncture site and the container by vertically moving the puncture site holding mechanism, the container holding mechanism, or the container held by the container holding mechanism while the compression mechanism performs the operation of compressing and releasing the puncture site.
