Abstract
Abstract A portable, miniature, self-powered, high-speed, clinical centrifuge having a housing, a motor, an energizing means, a rotor head and a rotor head cover. The energizing means for the motor is capable of being charged by a removable charger. Operation of the centrifuge rotates the rotor head at a high speed thereby separating blood cells from blood plasma within a capillary tube located within said rotor head. A timer regulates the length of time the centrifuge is in operation.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
148 words
A miniature, portable, self-powered, high-speed clinical centrifuge comprising a housing, a motor means fixedly secured to said housing, a means for energizing said motor means adjacent thereto, a rotor head having a plurality of grooves therein operably connected to said motor means, a rotor head cover removably secured to said motor means and proximate said rotor head, a lid removably secured to said housing for covering said rotor head and rotor head cover, said housing having a base portion, said base portion having a charger jack mounted therein and operably connected with said energizing means, and a removable charger having a charger plug thereon capable of being inserted within said charger jack for charging said energizing means, whereby energizing of said motor means operates to rotate said rotor head at a high speed thereby separating blood cells from blood plasma within a capillary tube located within said grooves.
Claim 2
Dependent Claim
148 words
A miniature, portable, self-powered, high-speed clinical centrifuge comprising a housing, a motor means fixedly secured to said housing, a means for energizing said motor means adjacent thereto, a rotor head having a plurality of grooves therein operably connected to said motor means, a rotor head cover removably secured to said motor means and proximate said rotor head, a lid removably secured to said housing for covering said rotor head and rotor head cover, said housing having a base portion, said base portion having a charger jack mounted therein and operably connected with said energizing means, and a removable charger having a charger plug thereon capable of being inserted within said charger jack for charging said energizing means, whereby energizing of said motor means operates to rotate said rotor head at a high speed thereby separating blood cells from blood plasma within a capillary tube located within said grooves.
Claim 3
Dependent Claim
32 words
A miniature, portable, self-powered, high-speed clinical centrifuge as defined in claim 1 further comprising a timer mechanism within said housIng and operably associated with said motor means for regulating the operation thereof.
Claim 4
Dependent Claim
36 words
A miniature, portable, self-powered, high-speed clinical centrifuge as defined in claim 2 further comprising a brake within said housing and operably associated with said motor means for quickly bringing said rotor head to a total stop.
Claim 5
Dependent Claim
43 words
A miniature, portable, self-powered, high-speed clinical centrifuge as defined in claim 3 wherein said motor means is provided with a shaft secured thereto, said rotor head being fixedly secured to said shaft and said rotor head cover being removably secured to said shaft.
Claim 6
Dependent Claim
44 words
A miniature, portable, self-powered, high-speed clinical centrifuge as defined in claim 4 wherein said rotor head further has a raised lip around its periphery, said lip and said grooves being lined with a thin resilient substance to prevent breakage of capillary tubes placed therein.
