One-hand pulse pump
First Claim
1. A hand pump for dispensing a fluid, the hand pump comprising:
- (a) a dispensing barrel having a chamber;
(b) a finger rest rigidly attached to the dispensing barrel, the finger rest having a loading chamber formed therein, the loading chamber being fluid coupled to the chamber of the dispensing barrel through an inlet passageway;
(c) a plunger having a tip end slidably received within the chamber of the dispensing barrel; and
(d) a handle mounted to the plunger.

Abstract
A hand operated, fluid dispensing pump includes a body that slidably interacts with a handle. The body includes a valve housing fluid coupled with an inlet passageway, an outlet passageway, and a dispensing barrel. A finger rest rigidly projects from the dispensing barrel. A loading chamber is recessed within the finger rest and is configured to receive a fluid supply syringe. A plunger, mounted to the handle, is slidably received within the dispensing barrel. As the plunger is advanced within the barrel, fluid is dispensed from the pump. Once the plunger is fully advanced, a spring disposed between the body and the handle automatically retracts the plunger within the barrel. As the plunger is retracted within the barrel, the barrel is automatically filled with a fluid from the fluid supply syringe.
