Coagulation timer

摘要

A coagulation timer device is used to monitor the bleeding time of a patient to determine the amount of time required to achieve clotting. The coagulation timer device includes a carrier member, a linearly oriented absorbing medium which is affixed to the carrier member and a bag member which overlays the carrier member and the medium. The medium, such as filter paper or the like, is used to blot blood from an incision which has been formed through the skin. The medium is affixed to the carrier member and includes a plurality of segments each of which are defined by a scalloped edge portion which extends beyond the edges of the carrier member. The segments are used one at a time at predetermined intervals to blot the blood by touching the scalloped edge to the blood. Indicia is provided on the carrier member to let a medical person or technician know where the medium should be touched to the blood at each predetermined interval and provides a quick reference guide to let the technician know the amount of time that it has taken for the blood to clot. The bag member is affixed to the carrier member and is retractable to uncover the medium, while being replaceable to cover the medium.
