In-Vivo Platelet Function Test By Online Bleeding Volume Measurement
First Claim
1. A method for determining bleeding volume of a patient at a remote location, the method comprising the steps of:
- breaking a skin of the patient to induce bleeding;
absorbing blood of the patient on a flat absorbent material until the patient stops bleeding;
providing a reference surface area on the flat absorbent material;
scanning an image of the flat absorbent material including blotches of the absorbed blood and the reference surface area;
transmitting the scanned image to a service provider;
receiving a value associated with the bleeding volume of the patient from the service provider.

Abstract
A method for remotely determining a patient'"'"'s excessive bleeding tendency and a patient'"'"'s resistance to blood thinning medication is disclosed. An incision is made in the patient'"'"'s forearm. Blood oozing out of the incision is absorbed into a blotter paper until the bleeding stops. Blotches of blood formed on the blotter paper are captured as an image and sent to a service provider who calculates a value associated with the bleeding volume of the patient. The service provider retransmits a value associated with the bleeding volume back to the medical professional. To determine the resistance to blood thinning medication, one incision is made in the patient prior to administration of blood thinning medication. Blood oozing out of the incision is collected on blotter paper until the patient stops bleeding. A second incision is made in the patient. A second set of blotter paper is used to collect the blood oozing out of the incision until the bleeding stops. Both sets of blotter paper are sent to a service provider to calculate a value associated with the difference in bleeding volume. The service provider then retransmits the value associated with the difference in bleeding volume to the medical professional.

7. A method for determining bleeding volume of a patient at a remote location, the method comprising the steps of:
-
receiving a scanned image of a flat absorbent material including absorbed blood of the patient and a reference surface area; determining the area of absorbed blood; determining a value associated with the bleeding volume of the patient as a function of the area of absorbed blood and the reference surface area; transmitting the value to the remote location. - View Dependent Claims (8, 9)

10. A method of determining resistance of a patient to blood thinning medication, the method comprising the steps of:
-
prior to administering blood thinning medication, breaking a skin of the patient to induce bleeding; absorbing the blood of the patient on a first flat absorbent material until the patient stops bleeding; administering the blood thinning medication to the patient; after administering the blood thinning medication to the patient for a period of time so that the blood thinning medication achieves maximum effect, breaking the skin of the patient to induce bleeding; absorbing the blood of the patient on a second flat absorbent material until the patient stops bleeding; transmitting one or more images of the first and second flat absorbent material to a service provider; and receiving a value associated with a difference or ratio in bleeding volume prior to and after administration of the blood thinning medication from the service provider based on the one or more images of the first and second flat absorbent material. - View Dependent Claims (11)
