Abstract

A syringe including a front end and a rear end. A front portion of the syringe having an axially extending hollow needle that projects from the front end. The rear end of the needle is in fluid communication with a space that extends substantially to the rear end of the syringe. A plunger extends axially and is movable to and fro in the space and is designed such that, when drawn out, it sucks liquid through the needle and, when pressed in, discharges liquid through the needle. A radially projecting flange element in the front portion of the syringe is designed in such a way that it can be gripped between the thumb and middle finger of a user'"'"'s hand. The syringe is dimensioned so as to permit injection using the index finger of the same hand. A capsule device for at least partially accommodating a syringe. A syringe device.

Claims

1. A syringe comprising:

a front end and a rear end,

an axially extending hollow needle that projects from the front end, a rear end of the needle being in fluid communication with a space that extends substantially to the rear end of the syringe,

a plunger which extends axially and is movable to and fro in the space and which is designed such that, when drawn out, the plunger sucks liquid through the needle and, when pressed in, discharges liquid through the needle, and

a radially projecting flange element designed in such a way that the flange element can be gripped between a thumb and middle finger of a hand of a user, wherein the flange element has an extent in an axial direction and is circumferentially arranged in a front portion of the syringe, the syringe being dimensioned so as to permit injection using an index finger of a same hand.

2. The syringe according to claim 1, wherein the flange element has a substantially oval cross section.

3. The syringe according to claim 1, wherein the flange element has a substantially circular cross section.

4. The syringe according to claim 1, wherein the flange element comprises at least two circumferential flange portions arranged substantially parallel to one another.

5. The syringe according to claim 1, wherein the flange element is flexible.

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

a sleeve element, and

a release configured to releasably secure the a sleeve element, said release being arranged on at least one of the front portion and a rear portion of the syringe.

7. The syringe according to claim 1, wherein with the plunger drawn out, the syringe has a length in the range of 30-80 mm.

9. The syringe device according to claim 1, further comprising:

a release configured to releasably secure at least one of the front sleeve element and the rear sleeve element.

8. A syringe devices comprising:

a syringe comprising a front end and a rear end, an axially extending hollow needle that projects from the front end, a rear end of the needle being in fluid communication with a space that extends substantially to the rear end of the syringe, a plunger which extends axially and is movable to and fro in the space and which is designed such that, when drawn out, the plunger sucks liquid through the needle and, when pressed in, discharges liquid through the needle, and a radially projecting flange element designed in such a way that the flange element can be gripped between a thumb and middle finger of a hand of a user, wherein the flange element has an extent in an axial direction and is circumferentially arranged in a front portion of the syringe, the syringe being dimensioned so as permit injection using an index finder of a same hand, and

a capsule device comprising at least one rear sleeve element which is dimensioned such that, when the plunger of the respective syringe is drawn out, the at least one rear sleeve element will cover the protruding plunger of the respective syringe in such a way that, when the sleeve element is engaged over the plunger, the plunger cannot be pressed in, wherein the capsule device further comprises at least one front sleeve element designed to cover the needle of a respective syringe when the syringe is not in use, the flange element of the syringe being designed such that, upon engagement of the front sleeve element, the flange element acts as a limit stop for the front sleeve element, and wherein the flange element of the syringe is designed such that, upon engagement of the rear sleeve element, the flange element acts as a limit stop for the rear sleeve element.

10. The syringe device according to claim 8, wherein at least one of the front sleeve element and the rear sleeve clement comprises a a fastener configured to attach a key ring.

11. The syringe device according to claim 8, wherein at least two rear sleeve elements are connected in parallel to one another to form a rear capsule part.

12. The syringe device according to claim 8, further comprising:

a seal configured to permit liquid-tight enclosure of the syringe by the sleeve elements.
