ROTATABLE FINGER LOOP FOR SYRINGE, SYRINGE CONFIGURED TO RECEIVE THE ROTATABLE FINGER LOOP AND ASSOCIATED METHODS

摘要

Finger control handles for conventional syringes are disclosed. The finger control handles may be configured to be assembled with a hand-held syringe, to be secured in place on a proximal portion of the barrel of the syringe and, when secured in place, to rotate freely about a circumference of the proximal portion of the barrel of the syringe. Systems that include the finger control handles and a hand-held syringe that is configured to capture the finger control handles are also disclosed, as are various methods of use, including methods for assembling the finger control handles with the syringe and methods for connecting the syringe to an elongated medical instrument, such as a catheter.

主权项

1. A medical system, comprising:
a syringe, including:
a barrel with a proximal end and a distal end, the barrel including:
a collar at or near the proximal end, the collar including a distally facing surface outside of an outer circumference of a remainder of the barrel; andat least one distal retention element protruding from an intermediate location on the collar, the at least one distal retention element including a proximally facing surface, the at least one distal retention element tapering toward the outer circumference of the remainder of the barrel from the proximally facing surface to a more distal location along a length of the barrel; anda proximal portion defined between the collar and the at least one distal retention element; anda plunger insertable into and removable from an interior of the barrel; and a finger control handle configured to be assembled with the barrel of the syringe, the finger control element including a body with a channel configured to receive the barrel and to reside over the proximal portion of the barrel in a manner that enables the finger control handle to rotate freely about a circumference of the proximal portion of the barrel, the finger control handle further including a pair of finger loops located on opposite sides of the body.
