ABSTRACT:
FIELD OF THE INVENTION
The invention pertains to methods and apparatus for reducing blood viscosity of living beings, and more particularly, to methods and apparatus for the automatic and safe removal of blood from a living being.
BACKGROUND OF INVENTION
The concept of removal of blood from a living being, also known as blood letting, has been known for centuries.
However, the particular physiological benefits of removing blood from a living being, and thereby allowing new blood to be created, has not been appreciated in the medical community. For example, a healthy menstruating female removes “old blood” from her body on a monthly basis that is replenished with “fresh blood.” A male, on the other hand, does not experience such a cycle and his circulatory system re-circulates “old blood.”
Therefore, there remains a need to provide an individual with the ability to safely and automatically blood let while providing a safe and non-biohazardous way of disposing of the removed blood.
SUMMARY OF THE INVENTION
An apparatus for permitting automatic, self-blood letting of a living being of a predetermined amount of blood (e.g., approximately 1 pint) and which renders the removed blood non-biohazardous (e.g., using an internal micro-biological inactivating agent) for safe disposal.
A method of permitting automatic, self-blood letting of a living being of a predetermined amount of blood while rendering the removed blood non-biohazardous for safe disposal. The method comprises: (a) providing a blood collector that normally has an expanded state and which contains a micro-biological inactivating agent (e.g.,bromine, chlorine, Methylene blue (MB) and its derivatives azure A, B, C and thionine); (b) evacuating the blood collector of atmospheric pressure to form a compressed state of the blood collector; (c) coupling a releasable biasing member to the blood collector to maintain the blood collector in the compressed state until a desired time; (d) coupling the blood vessel of the living being to the blood collector; (e) activating the releasable biasing member to cause the blood collector to rapidly expand to draw the predetermined amount of blood into the blood collector; (f) de-coupling the blood collector from the blood vessel; and (g) discarding the blood collector.
