Abstract: Disclosed is an ambulatory therapeutic fluid delivery device. The device includes at least one housing connectable to a cannula, the at least one housing retaining a reservoir to hold the therapeutic fluid. The device also includes a mechanically powered pumping mechanism to cause delivery of at least some of the fluid from the reservoir, and a power-transfer mechanism to transfer manually-delivered power provided by a user to mechanically actuate the pumping mechanism.

Abstract: An infra-red vascular angiography system comprising a readily displaceable infra-red camera including an infra-red optical assembly of high sensitivity capable of receiving and transmitting with minimal distortion an infra-red image of an object within an angular range of substantially .+-.45.degree. with respect to a normal to the object; infrared detector for detecting, the infra-red image transmitted from the optical assembly and converting it into successive electric output signals; video imaging device coupled to the detector for digitizing the output signals and converting them into successive digitized video image frames or successive portions of them; image processor coupled to the imaging device adapted to receive the successive video frames or portions of them so as to process them so as to form enhanced video images and display device coupled to the image processor.
