Abstract

A syringe system includes a first syringe, a second syringe, and at least any one of a first buoy located inside a first syringe barrel or a second buoy located inside a second syringe barrel. The first syringe includes the first syringe barrel. The second syringe includes the second syringe barrel coupled to the first syringe in such a manner that at least part of the second syringe barrel is movable from inside the first syringe barrel.

Claims (57)

1 . A syringe system comprising:

a first syringe comprising a first syringe barrel;

a second syringe comprising a second syringe barrel coupled to the first syringe in a movable manner from inside the first syringe barrel; and

at least one of a first buoy located inside the first syringe barrel or a second buoy located inside the second syringe barrel.

2 . The syringe system according to claim 1 , wherein

the first syringe further comprises a first gasket configured to be positioned inside the first syringe barrel, and

the second syringe comprises a second leading end portion configured to be coupled to the first gasket and moved from inside the first syringe barrel to inside the second syringe barrel.

3 . The syringe system according to claim 1 , further comprising a first needle, wherein

the first needle is a tubular needle comprising a first end configured to be inserted into a first gasket, the first gasket configured to be positioned inside the first syringe barrel, and a second end located on an opposite side to the first end, and

the second syringe barrel comprises a leading end portion configured to be coupled to the second end of the first needle.

4 . The syringe system according to claim 1 , comprising:

the second buoy located inside the second syringe barrel.

5 . The syringe system according to claim 1 , comprising:

the second buoy, wherein

the second buoy comprises two buoys having different masses per unit volume.

6 . The syringe system according to claim 1 , comprising:

the first buoy located inside the first syringe barrel.

7 . The syringe system according to claim 6 , wherein

the first buoy comprises two buoys having different masses per unit volume.

8 . The syringe system according to claim 1 , comprising:

the first buoy and the second buoy.

9 . The syringe system according to claim 8 , wherein

a mass per unit volume of the first buoy is heavier than a mass per unit volume of the second buoy.

10 . The syringe system according to claim 1 , further comprising:

a third syringe comprising a third syringe barrel, wherein

the second syringe and the third syringe are configured to be coupled from inside the second syringe barrel to inside the third syringe barrel.

11 . The syringe system according to claim 10 , wherein

the third syringe comprises at least one third buoy located inside the third syringe barrel.

12 . The syringe system according to claim 11 , wherein

a mass per unit volume of the first buoy is heavier than a mass per unit volume of the third buoy.

13 . The syringe system according to claim 11 , wherein

a mass per unit volume of the second buoy is lighter than a mass per unit volume of the third buoy.

14 . The syringe system according to claim 10 , wherein

at least part of the third syringe is configured to be positioned inside the second syringe barrel.

15 . The syringe system according to claim 10 ,

wherein

an internal volume of the third syringe barrel is smaller than an internal volume of the second syringe barrel.

16 . The syringe system according to claim 1 , wherein

at least part of the second syringe is configured to be positioned inside the first syringe barrel.

17 . The syringe system according to claim 1 , wherein

the internal volume of the second syringe barrel is smaller than an internal volume of the first syringe barrel.

18 . The syringe system according to claim 1 , wherein

the first buoy has a substantially circular flat plate shape, a disk shape with a conical surface in which a center portion protrudes relative to a peripheral edge portion, or a disk shape with a curved surface in which a center portion protrudes relative to a peripheral edge portion.

19 . The syringe system according to claim 1 , wherein

the second buoy has a substantially circular flat plate shape, a disk shape with a conical surface in which the center portion protrudes relative to the peripheral edge portion, or a disk shape with a curved surface in which the center portion protrudes relative to the peripheral edge portion.

20 . The syringe system according to claim 1 , wherein

the first buoy comprises a first covering portion configured to cover at least part of the first gasket configured to be positioned inside the first syringe barrel.

21 . The syringe system according to claim 1 , wherein

the second buoy comprises a second covering portion configured to cover at least part of a second gasket configured to be positioned inside the second syringe barrel.

22 . The syringe system according to claim 18 , wherein

the first buoy comprises any of a through hole, a net-like portion, and a nonwoven fabric-like portion in at least one location.

23 . The syringe system according to claim 19 , wherein

the second buoy comprises any of a through hole, a net-like portion, and a nonwoven fabric-like portion in at least one location.

24 . The syringe system according to claim 1 , wherein

the first buoy and the second buoy comprise two or more buoy members having different masses per unit volume.

25 . The syringe system according to claim 1 , wherein

a mass per unit volume of the first buoy is heavier than a mass per unit volume of whole blood of a human.
