title: [A newer position-independent perfusable drop counter. Function principle, technical variations, calculation bases and use possibilities].
abstract: The principles of construction and the basis for calculation of a dropper for infusion apparatuses, functioning independently of its position, are explained and exemplified. By means of suitable shaping and exact calculation the volume of the device can be reduced to a quarter of the volume of a spherical device of corresponding function. A preferred possibility of application consists in combining the device with a flexible container and an artificial pressure device.
