DEVICE FOR SCANNING CONTAINERS FILLED WITH LIQUID

摘要

DEVICE FOR SCANNING CONTAINERS FILLED WITH LIQUID An analyzer is described comprising a device for scanning containers filled with body fluid and held in a tray, the openings of which are sealed by means of a sealing member, e.g. a stopper or cup. The opto-electronic scanning device consists of a receiver and a transmitter comprising a plurality of vertically arranged receiver elements and transmitter elements, respectively, facing each other in a registered manner. Receiver and transmitter are arranged on a pivotable transport path for the containers between an input station and two processing stations. During the transport of container through the scanning device, the intensity of the scanning beam of the transmitter elements can be controlled from a low to a high level by means of a control unit comprising a microprocessor. Shape and/or size of the sealing member is thereby detected by means of the low intensity and transmittance or type of the sealing member by means of the high intensity. In this way, the transport direction of the containers can be controlled such that a container having a stopper is moved to an opening means and a container with or without a cup is moved to an aspirator for body fluids.
