Abstract
Abstract A mechanical drive system for driving a syringe, or other fluid infusion system, over extended period of times, which drive system also provides manual advance and quick release features. Manual advance and quick release is selectively provided by mechanically decopuling the gear train from the syringe drive mechanism.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
191 words
An improved mechanical drive arrangement for a fluid infusion device comprising: rotary drive means for providing a driving torque to a first shaft, means mechanically coupled to said rotary drive means for rotationally advancing said rotary drive means in a first and second direction, a first driving gear and a first pinion gear fixed coaxially to said first shaft, said first shaft cooperating with slotted support members for selectively allowing lateral displacement of said first driving gear and said first pinion gear, a second driving gear and a second pinion gear fixed coaxially to a second shaft, said second driving gear mechanically coupled to a transport rack for providing mechanical displacement of said transport rack, a third driving gear and a third pinion gear fixed coaxially to a third shaft, said third shaft cooperating with slotted support members for selectively allowing displacement of said third driving gear and said third pinion gear, said third pinion gear being mechanically coupled to said first driving gear, and rate control means for fixing a time rate of rotation of said second shaft, said third driving gear being mechanically coupled to said rate control means.
Claim 2
Dependent Claim
191 words
An improved mechanical drive arrangement for a fluid infusion device comprising: rotary drive means for providing a driving torque to a first shaft, means mechanically coupled to said rotary drive means for rotationally advancing said rotary drive means in a first and second direction, a first driving gear and a first pinion gear fixed coaxially to said first shaft, said first shaft cooperating with slotted support members for selectively allowing lateral displacement of said first driving gear and said first pinion gear, a second driving gear and a second pinion gear fixed coaxially to a second shaft, said second driving gear mechanically coupled to a transport rack for providing mechanical displacement of said transport rack, a third driving gear and a third pinion gear fixed coaxially to a third shaft, said third shaft cooperating with slotted support members for selectively allowing displacement of said third driving gear and said third pinion gear, said third pinion gear being mechanically coupled to said first driving gear, and rate control means for fixing a time rate of rotation of said second shaft, said third driving gear being mechanically coupled to said rate control means.
Claim 3
Dependent Claim
44 words
An improved mechanical drive arrangement for a fluid infusion system in accordance with Claim 1 wherein said transport rack is arranged adjacent to said fluid infusion system whereby mechanical displacement of said transport rack provides dispersal of fluid contained within said fluid infusion system.
Claim 4
Dependent Claim
55 words
An improved mechanical drive arrangement for a fluid infusion system in accordance with Claim 2, wherein rotational advancement of said rotary drive means in said first direction laterally displaces said first driving gear and said first pinion gear, said lateral displacement resulting in mechanical decoupling between said first pinion gear and said second driving gear.
Claim 5
Dependent Claim
55 words
An improved mechanical drive arrangement for a fluid infusion system in accordance with Claim 3, wherein rotational advancement of said rotary drive means in said second direction laterally displaces said third driving gear and said third pinion gear, said lateral displacement resulting in mechanically decoupling between said third pinion gear and said first driving gear.
Claim 6
Dependent Claim
33 words
An improved mechanical drive arrangement for a fluid infusion system in accordance with Claim 4, wherein there is further provided means for mechanically decoupling said rotationally advancing means from said rotary drive means.
