MECHANICAL INJECTION PUMP AND METHOD OF USE

摘要

A mechanical injection pump wearable by a user to deliver a first fluid and a second fluid, including: a pump body having a first fluid chamber to hold the first fluid and a second fluid chamber to hold the second fluid; a common connector having a first inlet, a second inlet, and a common outlet; a first fluid system including the first fluid chamber, a first button drive connected to the first fluid chamber, and first fluid delivery path between the first fluid chamber and the first inlet; and a second fluid system including the second fluid chamber, a second button drive connected to the second fluid chamber, and second fluid delivery path between the second fluid chamber and the second inlet. Force by the user on the button drive increases pressure within the fluid chamber to drive a predetermined volume of the fluid from the fluid chamber.

1. A mechanical injection pump wearable by a user to deliver a first fluid and a second fluid, the mechanical injection pump comprising:
a pump body defining a first fluid chamber and a second fluid chamber, the first fluid chamber being operable to hold the first fluid and the second fluid chamber being operable to hold the second fluid; a common connector having a first inlet, a second inlet, and a common outlet; a first fluid system including the first fluid chamber, a first button drive operably connected to the first fluid chamber, and a first fluid delivery path in fluid communication between the first fluid chamber and the first inlet; and a second fluid system including the second fluid chamber, a second button drive operably connected to the second fluid chamber, and a second fluid delivery path in fluid communication between the second fluid chamber and the second inlet; wherein force by the user on the first button drive is converted to increased pressure within the first fluid chamber to drive a predetermined volume of the first fluid from the first fluid chamber, through the first fluid delivery path to the common connector, and out the common outlet; and force by the user on the second button drive is converted to increased pressure within the second fluid chamber to drive a predetermined volume of the second fluid from the second fluid chamber, through the second fluid delivery path to the common connector, and out the common outlet.
