Syringe with multiple compartments

Claim 2

A syringe for administering medicaments and for collecting of fluids comprising: a. an outer cylinder barrel, b. a hypodermic needle secured at one end of said outer cylinder barrel, c. an inner cylinder barrel telescopically and slideably disposed within said outer cylinder barrel, d. a piston rod telescopically and slideably disposed within said inner cylinder barrel, e. said innEr cylinder barrel provided with a valve means, f. said valve means comprising 1. an inward bent flange being an integral part at said inner cylinder barrel end and forming an oval-shaped opening, 2. a sealing member having a passageway therethrough and made of resilient material complementally disposed about said oval opening for rotation within said flange, 3. said sealing member shaped to complement within said outer cylinder barrel end area adjacent said needle and having antirotational means coacting with said outer cylinder inside area adjacent said needle, and g. whereby, when said inner cylinder is positioned against said outer cylinder inside area adjacent said needle, said antirotational means prevents rotation of said sealing member so that upon 90* rotation of said inner cylinder barrel said flange with oval opening will turn and misalign with said sealing member complementing resilient material so that said passageway is squeezed shut, thereby separating said inner barrel from said outer barrel volume.

Claim 3

a sealing member having a passageway therethrough and made of resilient material complementally disposed about said oval opening for rotation within said flange,

Claim 4

a sealing member having a passageway therethrough and made of resilient material complementally disposed about said oval opening for rotation within said flange,

Claim 5

A syringe for administering medicaments and for collecting of fluids comprising: a. an outer cylinder barrel, b. a hypodermic needle, having a bore, secured at one end of said outer cylinder barrel, c. an inner cylinder barrel telescopically and slideably disposed within said outer cylinder barrel, d. a piston rod telescopically and slideably disposed within said inner cylinder barrel, e. said inner cylinder barrel provided with a valve means having a passageway for communication of said inner cylinder barrel with said outer cylinder barrel inside bottom adjacent and in alignment with said needle bore, f. said valve means comprising a flange formed integrally from said inner cylinder barrel bottom portion and extending radially inwardly to and substantially perpendicularly with said syringe longitudinal axis and said flange having radially varying dimensions so that an oval opening is formed within, g. a seal member complementing about said flange within said oval opening in slideably secured fashion and provided with means for preventing rotation of said seal member when said seal member is located at said outer cylinder barrel inside bottom adjacent said bore, h. said flange adapted to actuate opening and closing of said passageway in said valve means within a 90* rotational movement of said inner cylinder barrel in reference with said outer cylinder barrel about said inner cylinder barrel longitudinal axis, whereby said seal member resilient material is adapted to be compressed upon 90* rotation of said inner cylinder barrel when said seal member is in said rotation preventing location by said oval opening rotation of said flange so that said minor axis of said oval opening upon said 90* rotation one way coincides with said major axis of said complementing stationary resilient seal member so that said passageway within said valve means closes through displacement of said resilient material.

Claim 6

A syringe for administering medicaments and for collecting of fluids comprising: a. an outer cylinder barrel, b. a hypodermic needle, having a bore, secured at one end of said outer cylinder barrel, c. an inner cylinder barrel telescopically and slideably disposed within said outer cylinder barrel, d. a piston rod telescopically and slideably disposed within said inner cylinder barrel, e. said inner cylinder barrel provided with a valve means having a passageway for communication of said inner cylinder barrel with said outer cylinder barrel inside bottom adjacent and in alignment with said needle bore, f. said valve means comprising a flange formed integrally from said inner cylinder barrel bottom portion and extending radially inwardly to and substantially perpendicularly with said syringe longitudinal axis and said flange having radially varying dimensions so that an oval opening is formed within, g. a seal member complementing about said flange within said oval opening in slideably secured fashion and provided with means for preventing rotation of said seal member when said seal member is located at said outer cylinder barrel inside bottom adjacent said bore, h. said flange adapted to actuate opening and closing of said passageway in said valve means within a 90* rotational movement of said inner cylinder barrel in reference with said outer cylinder barrel about said inner cylinder barrel longitudinal axis, whereby said seal member resilient material is adapted to be compressed upon 90* rotation of said inner cylinder barrel when said seal member is in said rotation preventing location by said oval opening rotation of said flange so that said minor axis of said oval opening upon said 90* rotation one way coincides with said major axis of said complementing stationary resilient seal member so that said passageway within said valve means closes through displacement of said resilient material.

Claim 7

A syringe as claimed in claim 2 wherein said means for preventing rotation of said seal member comprises a nonsymmetric surface complementation, being a plug and recess means located at said seal member surface and said outer cylinder barrel inside bottom.

Claim 8

said sealing member shaped to complement within said outer cylinder barrel end area adjacent said needle and having anti-rotational means coacting with said outer cylinder inside area adjacent said needle, and g. whereby, when said inner cylinder is positioned against said outer cylinder inside area adjacent said needle, said anti-rotational means prevents rotation of said sealing member so that upon 90* rotation of said inner cylinder barrel said flange with oval opening will turn and misalign with said sealing member complementing resilient material so that said passageway is squeezed shut, thereby separating said inner barrel from said outer barrel volume.

Claim 9

said sealing member shaped to complement within said outer cylinder barrel end area adjacent said needle and having anti-rotational means coacting with said outer cylinder inside area adjacent said needle, and g. whereby, when said inner cylinder is positioned against said outer cylinder inside area adjacent said needle, said anti-rotational means prevents rotation of said sealing member so that upon 90* rotation of said inner cylinder barrel said flange with oval opening will turn and misalign with said sealing member complementing resilient material so that said passageway is squeezed shut, thereby separating said inner barrel from said outer barrel volume.
