Abstract
Abstract An assembly for loading and dispensing varying amounts of fluid from multiple syringes is disclosed. A body member having spaced-apart surfaces A o and B o coacts with a handle member having spaced-apart surfaces A 1 and B 1 (A 1 and B 1 are either fixedly spaced or variably spaced) parallel to the surfaces A o and B o . The handle member is mounted for relative reciprocal movement with respect to the body member in a direction D o the same as a vector perpendicular to the surfaces A o and B o . A plurality of syringe actuators each associated with an individual one of the syringes is included, and they are mounted for relative movement with respect to the body member. Each syringe actuator has actuating surfaces for respective contact with the surfaces A o and B o on the body member and A 1 and B 1 on the handle member.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
128 words
An assembly for loading and dispensing varying amounts of fluid from multiple syringes comprising a body member having spaced-apart surfaces A 0 and B 0 , a handle member having spaced-apart surfaces A 1 and B 1 parallel to said surfaces A 0 and B 0 and mounted for relative reciprocal movement with respect to said body member in a direction D 0 the same as a vector perpendicular to said surfaces A 0 and B 0 , and a plurality of syringe actuators each associated with an individual one of said syringes and mounted for relative movement with respect to said body member, each syringe actuator having actuating surfaces for respective contact with said surfaces A 0 , B 0 , A 1 and B 1 .
Claim 2
Dependent Claim
128 words
An assembly for loading and dispensing varying amounts of fluid from multiple syringes comprising a body member having spaced-apart surfaces A 0 and B 0 , a handle member having spaced-apart surfaces A 1 and B 1 parallel to said surfaces A 0 and B 0 and mounted for relative reciprocal movement with respect to said body member in a direction D 0 the same as a vector perpendicular to said surfaces A 0 and B 0 , and a plurality of syringe actuators each associated with an individual one of said syringes and mounted for relative movement with respect to said body member, each syringe actuator having actuating surfaces for respective contact with said surfaces A 0 , B 0 , A 1 and B 1 .
Claim 3
Dependent Claim
21 words
An assembly as in claim 1, in which said surfaces A 0 and B 0 are spaced-apart by a fixed distance.
Claim 4
Dependent Claim
103 words
An assembly as in claim 2, in which said handle member is relatively movable between positions in which: (a) the surfaces A 0 and A 1 are adjacent each other, and the surfaces B 0 and B 1 are adjacent each other, for manual actuation of said syringe actuators: (b) the surfaces A 0 and B 1 are adjacent each other, representing completion of ganged movement of said syringe actuators in aspirating fluid into said syringes; (c) the surfaces A 1 and B 0 are adjacent each other, representing completion of ganged movement of said syringe actuators in dispensing fluid from said syringes.
Claim 5
Dependent Claim
32 words
An assembly as in claim 3, in which said surfaces A 0 and B 0 are spaced-apart by slightly less than the distance between said surfaces A 1 and B 1 .
Claim 6
Dependent Claim
36 words
An assembly as in claim 1, in which said handle member is formed from separate handle pieces independently movable, one handle piece having said surface A 1 and the other having said surface B 1 .
Claim 7
Dependent Claim
72 words
An assembly as in claim 5, in which one handle piece moves all said syringe actuators in one direction for aspiration of fluid into said syringes, and the other of said handle pieces moves all said syringe actuators in an opposite direction for dispensing fluid from said syringes, and in which said handle pieces may be spaced-apart by a sufficient distance to permit said syringe actuators to be moved individually and manually.
Claim 8
Dependent Claim
17 words
An assembly as in claim 3 or 6, in which said actuating surfaces lie in plural planes.
Claim 9
Dependent Claim
17 words
An assembly as in claim 7, in which there are at least two of said plural planes.
Claim 10
Dependent Claim
17 words
An assembly as in claim 7, in which there are more than two of said plural planes.
