Abstract
A drop controller is provided for controlling the rate at which drops of a fluid flow to a patient. The drop controller includes a socket for receiving a cassette having a constrainable member adjustable in position. This constrainable member controls the size of an adjustable passage through which the fluid flows to the patient. The socket is defined by a plurality of spring fingers for releasably holding the cassette. A lever is mounted on the housing for the drop controller and is pivotable to a cocked position by the cassette when the cassette is disposed in the socket. The lever can be pivoted to a second position to obtain a removal of the cassette from the socket. An arrangement is also included for releasably and adjustably positioning the controller relative to a support pole. The arrangement includes a shaft and an arm at the end of the shaft for providing an engagement of the support pole between the arm and the housing of the controller. The arrangement further includes a rotatable knob for pivoting the controller relative to the pole to adjust the disposition of the front face of the controller relative to the viewing position of hospital attendants.
