Abstract
A blood collecting device collects blood in a short time after puncture without scattering the blood into the open air other than a container for collecting the blood. One of representative blood collecting devices has a container unit that includes a screw portion, a holder that holds the container unit serving as a system whose one end is closed, a puncture unit that can be attached to the container or the holder, a through-hole of the puncture unit, and a puncture unit protection member that protects the puncture unit and the container unit.
Claims10
A blood collecting device comprising:
- a container unit that has an opening portion and a closing portion, and that holds the opening portion in a state where the opening portion faces upward;
- a fixing unit that fixes a blood collecting target in a state where the blood collecting target faces the opening portion;
- a pressure changing unit that pressurizes the blood collecting target or applies negative pressure into a space surrounded by the blood collecting target and the container, or that performs both of these in combination with each other;
- a puncture unit that is positioned below the container unit, and that punctures the blood collecting target after pressure is changed by the pressure changing unit;
- and
- a lid that closes the opening portion of the container containing blood,
- wherein the container unit has a slide mechanism which slides with respect to the fixing unit in a horizontal direction.
A blood collecting device comprising:
- an upper disk that has at least one through-hole;
- a lower disk that is positioned below the upper disk, and that is rotatable independent of the upper disk;
- a negative pressure source that applies negative pressure to a surrounding environment of a blood collecting target pressed against the through-hole;
- a puncture unit that is fixed to the lower disk, and that punctures the blood collecting target after pressure is changed by a pressure changing unit;
- and
- a container unit that has an opening portion and a closing portion, and that is fixed to the lower disk in a state where the opening portion faces upward.
