Method of measuring bleeding volume

Abstract

A method of measuring blood clotting ability of a patient. A known volume of blood is dispensed on a reference disc of blotter paper, such that at least one reference blotch is formed on the reference disc. The surface area of the reference blotch formed on the reference disc, such that a relationship between the volume of blood and the surface area of the reference blotch can be obtained. An incision is made at the patient. A piece of blotter paper to the incision is applied to the incision to collect blood flowing therefrom, such that at least one blotch is formed on the piece of blotter paper. The surface area of the blotch formed on the piece of blotter paper is measured. The volume of the blood absorbed blood by the blotter paper is calculated according to the relationship between the blood volume and the surface area of the blotch.

1 - 14 . (canceled) 
   
   
       15 . A method of indicating blood clotting ability of a patient, the method comprising the steps of:
 a) breaking a skin of the patient to induce bleeding of blood;   b) collecting blood of the patient obtained during step a) on a blotter paper until the patient stops bleeding; and   c) calculating a total surface area of the collected blood on the blotter paper of step (b) wherein the total surface area is indicative of total blood volume and the blood clotting ability of the patient.   
   
   
       16 . The method of  claim 15  further comprising the step of locating a blood pressure tourniquet on an arm of the patient pumped to a predetermined pressure to assure standardized capillary blood pressure.
