an open proximal end for receiving a plunger, said open proximal end terminating in a rim having a pair of opposed flanges extending outwardly thereon, said proximal end having a distal surface and a proximal surface; and a distal end for mounting a medical fluid conduit thereon;
b) a plunger, having an outside diameter equal to or slightly greater than the inside diameter of said cylindrical barrel, said plunger slideably positioned in said cylindrical barrel;
c) an extension grip comprising an upwardly extending portion located inside or outside of a syringe, wherein said upwardly extending portion is of a length less than the length of the plunger, and wherein said upwardly extending portion further includes an integral finger support located at an uppermost portion thereof.
12. The finger grip combination of claim 11, wherein the grip is removable from the barrel of the syringe.
13. The finger grip combination of claim 12, wherein the syringe further comprises at least one positive lock member located on the barrel of the syringe, to slidably receive the grip at any one of a number of selected locations along the barrel of the syringe.
14. The finger grip combination of claim 13, wherein the at least one positive lock member is fitted to the inside of the barrel of the syringe.
15. The finger grip combination of claim 13, wherein the at least one positive lock member is located along the length of the outside of the barrel of the syringe.
16. The finger grip combination of claim 11, wherein the upwardly extending portion comprises two arm members located on opposite sides of the syringe, each arm member comprising a finger support located at a top portion thereof and extending in a generally perpendicular direction from the arm member, where said support is one of a) a geometrical shape extending outwardly on said arm member, and b) an open ring shape configured to receive a user’s fingers therein.
17. The finger grip combination of claim 11, wherein the grip is integrally formed with the syringe.
18. The finger grip combination of claim 12, wherein the finger grip is formed as a substantially U-shaped structure having two upwardly extending arms integral with a cross member that has an upper surface and a lower surface, said cross member having a circular opening formed therein that allows the grip to be inserted over the barrel of the syringe and further comprising a seal having a circular opening formed therein, wherein the seal is attached to the lower surface of the cross member and the seal is of a diameter substantially equal to the diameter of the syringe barrel and the seal secures the grip to the barrel of the syringe when the grip is placed over the barrel of the syringe.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. An extraction mechanism, comprising:
a release part configured to release an engagement between a cage and a device inserted into the cage and engaged and latched to the cage;
an ejection part configured to eject the device out of the cage; and
a release lever configured to activate the release part and the ejection part, wherein
the extraction mechanism is provided to the device.
2. The extraction mechanism according to claim 1, wherein
the release lever is configured to be pushed to a release direction to activate the release part and the ejection part, the release direction being different from an insertion direction and an extraction direction of the device.
3. The extraction mechanism according to claim 1, comprising:
a slider slidable to an insertion direction and an extraction direction of the device;
an ejector slidable to the insertion direction and the extraction direction; and
an energization member located between the slider and the ejector, and configured to energize the slider to the extraction direction and to energize the ejector to the insertion direction, wherein
the ejector is configured to contact with the cage and to catch an energization force of the energization member when the device is latched to the cage,
by the release lever pushed to a release direction, the slider is configured to slide to the insertion direction, thereby compressing the energization member to charge energy in the energization member, and releasing the engagement between the cage and the device, and
by release of the engagement between the cage and the device, the energy charged in the energization member is configured to be released to push the slider to the extraction direction, thereby ejecting the device out of the cage.
