COLLECTION AND DELIVERING DEVICE FOR LIQUID SAMPLE

摘要

PURPOSE:To perform a series of operations automatically and accurately by feeding a fixed amount of sample liquid to an analyzer once extracted with a syringe section from the stored liquid sampled by a collecting section based on the control with a control section. CONSTITUTION:One end of a blood collecting tube 1 is connected direct to the blood vessel in vivo while the other end thereof is introduced into a primary sample liquid reservoir 22. A specified amount of blood or the like sampled in cooperation with solenoid valves SV1-SV3 and a roller 2 is stored temporarily into a sample liquid reservoir 22. Blood or the like sent from a blood collecting section (a) through a dilivering tube 26 is once stored into a secondary sample liquid reservoir 27 and then, sucked by a specified amount with a syringe 28 driven by a motor M3. Thereafter, it is delivered from the syringe 28 with the reversion of the motor M3 to an analyzer 31 through an injection tube 29 for required analysis.
