Abstract
A liquid sampler includes: a metering pump which is composed of a cylinder having opposite end openings and a cylindrical cavity, a piston inserted in the cavity from one of the openings of the cylinder, and a driving source for reciprocally and linearly moving the piston; and a pipette directly connected to the other opening of the cylinder.
Claims22
A liquid sampler comprising:
- a metering pump including a cylinder having opposite end openings and a cylindrical cavity, a piston inserted in the cavity from one of the openings of the cylinder, and a driving source for reciprocally and linearly moving the piston;
- and
- a pipette directly connected to the other opening of the cylinder.
A blood analyzer comprising:
- a liquid sampler which comprises a metering pump including a cylinder having opposite end openings and a cylindrical cavity, a piston inserted in the cavity from one of the openings of the cylinder, and a driving source for reciprocally and linearly moving the piston, and a disposable pipette attached to the other opening of the cylinder in a detachable manner;
- a driving mechanism for moving the liquid sampler horizontally and vertically;
- a liquid surface detecting section for detecting contact of a distal end of the pipette with a liquid surface;
- a controlling section for controlling the pump driving source and the driving mechanism upon reception of a signal from the liquid surface detecting section;
- a specimen vessel for containing a blood specimen;
- and
- an analyzing section for analyzing a test sample quantitatively dispensed out of the blood specimen from the specimen vessel by the liquid sampler.
