Abstract: A fixation system for fixing a bone fracture has a plurality of blocks, needles and rods that snap together in a framework around the fracture. The needles are inserted through the bone and the blocks are snapped onto the ends of the needles. Rods are snapped onto the blocks on both sides of the finger to keep the finger in place. Each block has two channels located on opposite sides and extending perpendicular to each other. The channels are structured so that a rod or needle having a diameter equal or slightly greater than one of the channels can be snapped into and retained by the channel.

Abstract: A device for carrying out microbiological examinations. There is provided a base for carrying a large number of samples of bacteria supporting nutrient material comprising an elongated strip of flexible material such as a material similar to photographic film. The bacteria supporting nutrient is applied at selected intervals in one or more bands along the length of the material. Spacers are provided on the material to enable same to be rolled or folded without disturbing the bacteria supporting nutrients. Irregularities, such as perforated knobs are provided along the length of said material for the anchoring thereon of said nutrient material. The elongated material may be rolled or folded for storage and/or incubation as desired, and subsequently unrolled for examination. The device may also be used for testing a resistance of bacteria to bacteriacides.
