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 device, 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 comprising a piston arranged in the space and a piston rod extending axially from the piston and out of the rear end of the syringe, wherein the piston is movable to and fro in the space, and wherein the plunger is designed such that, when drawn out to a drawn out position, wherein the piston rod extends axially from the rear end of the syringe, the plunger causes liquid to be drawn through the needle and, when pressed in, causes liquid to be discharged through the needle, and a radially projecting grip element configured and dimensioned to be gripped between a thumb and middle finger of a hand of a user while pressing on the piston rod using an index finger of the hand to carry out injection, wherein the grip element has an extent in an axial direction and is circumferentially arranged about a front portion of the syringe, and

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

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

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

3. The syringe device according to claim 1, wherein at least one of the front sleeve element and the rear sleeve element comprises a fastener configured to attach a key ring.

4. The syringe device according to claim 1, wherein the syringe device includes at least two of the rear sleeve elements connected in parallel to one another to form a rear capsule part.

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

a seal configured to permit liquid-tight enclosure of the syringe by the at least one front sleeve element or the at least one rear sleeve element.

6. The syringe device according to claim 1, wherein the grip element has a substantially oval cross section.

7. The syringe device according to claim 1, wherein the grip element has a substantially circular cross section.

8. The syringe device according to claim 1, wherein the grip element comprises at least two circumferential grip portions arranged substantially parallel to each other.

9. The syringe device according to claim 1, wherein the grip element is flexible.

10. The syringe device according to claim 1, wherein with the piston rod drawn out, the syringe has a length in the range of 30-80 mm.
