Abstract: A device for the intermediate pulsatory application of liquid pharmaceuticals or medicine is provided which has a changeable storage container for the pharmaceutical connected to one end of a flexible tube; on the other end of the tube are a catheter, a rolling pump which works on the tube, a drive motor for the rolling pump, and a timer for delivery impulse and pause time of the rolling pump. To control the operation of the drive motor, there is a microcomputer with program storage. The microcomputer is programmable by means of a keyboard. Proper program operation is always guaranteed, including when interruptions in the drive appear necessary, for example, to renew the battery serving as the energy source.
Abstract: For diagnosing bodily functions of a patient by analyzing individual, samples several blood samples are taken from the patient automatically in sequence at predetermined time intervals, collected together separately from one another, retained until the completion of all the samples, and then analyzed. The blood samples are fed into a single collecting container one after another in time sequence with the aid of a control valve and are held separated from one another by the introduction of a separating medium between them or they are fed individually in sequence into separate containers. An anti-coagulant prevents the blood samples coagulating before analysis, and so the patient can wear the apparatus for taking the blood samples and can move about and behave normally throughout the sampling sequence.
