Dental pump system for chemical caries removal
First Claim
1. A fluid dispensing apparatus for a flexible container having an outlet opening;
- said apparatus comprising a frame, a first wall member mounted to said frame;
a first container impinging means mounted to said frame in facing relation to said first wall member for movement toward and away from said first wall member respectively;
a heater means mounted to said frame for maintaining the fluid in said container at a predetermined temperature; and
drive means for actuating said first container impinging means between a first condition wherein it is urged toward said first wall member for squeezing the container therebetween to urge the liquid therefrom through said outlet opening and a second condition wherein said container impinging member is in a retracted position state relative to said wall member for permitting said container to return to a relaxed state for maintaining the liquid therein, said drive means comprising resilient means for normally urging said container impinging means toward said wall member and selectively actuatable release means for driving said impinging means against said resilient means and away from said wall member.

Abstract
A fluid dispensing system comprising a flexible container for simultaneously dispensing two fluids, and dispensing apparatus for controlled compression of the container. The flexible container includes two separate and independent compartments, each compartment comprising a reservoir portion for holding a supply of one of said two fluids, an outlet and a bi-ended labyrinthine portion communicating with the reservoir portion at one end thereof and with the outlet at the other end thereof. The dispensing apparatus includes a frame having a fixed wall and a movable container impinging member for movement relative to the fixed wall for squeezing the container therebetween to effect the dispensing of the two fluids therefrom substantially simultaneously.

12. A fluid dispensing system comprising:
- a frame, a first wall member mounted to said frame;
a first container impinging means mounted to the frame in facing relation to the first wall member and for movement toward and away from said first wall member respectively;
a flexible container for selectively, simultaneously dispensing two fluid substances contained therein and including means defining a pouch-like member having two separate and independent compartments, each compartment comprising a reservoir portion for holding a supply of one of said two fluids, outlet means, and a bi-ended labyrinthine portion communicating with said reservoir portion at one end thereof with said outlet means at the other end thereof;
heater means mounted to said frame for maintaining the fluid in said container at a predetermined temperature; and
drive means for actuating said impinging means between a first condition wherein it is urged toward said first wall member for squeezing the container therebetween to urge said fluids simultaneously therefrom through said respective openings and a second condition wherein the container impinging member is released from impinging engagement with said container means. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
