LIQUID COLLECTING DEVICE AND METHOD THEREOF

摘要

By means of this blood-collection device (1), by actively pressing/pulling blood by means of an aspirating/discharging mechanism (5), it is possible to rapidly collect blood even in the case of a depressed blood pressure due to the physiological state of the animal. Also, since a first duct (2) and second duct (3) having a predetermined length are provided, the present invention has ducts having a pre-stipulated length and a known volume, and so it is possible to collect a stipulated volume amount without measuring the length or amount collected of blood using a volume measurement means (for example, an optical measurement means). As a result of such a measurement means becoming unnecessary, the blood-collection device (1) can be more compact, and it is possible to reduce dead volume by means of being disposed in the vicinity of an animal. Furthermore, a connection terminal (6) and an opening/closing means (pinch valve (7)) are configured provided separately, and so replacing only one of either the connection terminal (6) or the opening/closing means (pinch valve (7)) is sufficient, and so it is possible to increase the efficiency of the replacement task.
