Four needles attached to bulbs and a spare bulb for distilled water (to coagulation of the blood at doning or transfusion needle insertion point?) by Johnsons (Country?). Four needles with triangular bulbs attached, two of the bulbs are labelled "Contents Distilled Water Non Sterile." There appears to be a spare bulb with the group. To stop coagulation of the blood at donning or transfusion needle insertion point?
