FLUID DELIVERY APPARATUS HAVING A GAS EXTRACTION DEVICE AND METHOD OF USE
First Claim
1. A gas extraction device for a fluid delivery apparatus, the gas extraction device comprising:
- a first layer comprising a fluid inlet aperture;
a vent membrane coupled to the first layer, the vent membrane configured to enable a gas to pass through the vent membrane and prevent a fluid from passing through the vent membrane, the vent membrane comprising a fluid inlet aperture in fluid communication with the fluid inlet aperture of the first layer;
a second layer coupled to the vent membrane opposite the first layer, the second layer comprising a first channel formed therethrough; and
an impermeable membrane coupled to the second layer opposite the vent membrane, wherein the first channel is in fluid communication with the fluid inlet aperture of the vent membrane and is configured to receive a fluid having a gas dispersed therein, and wherein the fluid is pressurized to move the fluid through the first channel against the vent membrane and to move the gas through the vent membrane.

Abstract
A gas extraction device for a fluid delivery apparatus includes a first layer and a vent membrane coupled to the first layer. The vent membrane enables a gas to pass through the vent membrane and prevents a fluid from passing through the vent membrane. The gas extraction device also includes a second layer coupled to the vent membrane opposite the first layer. The second layer has a first channel formed therethrough. In addition, the gas extraction device includes an impermeable membrane coupled to the second layer opposite the vent membrane. The first channel is configured to receive a fluid having a gas dispersed therein. The fluid is pressurized to move the fluid through the first channel against the vent membrane and to move the gas through the vent membrane.

14. A method of removing gas from a liquid, said method comprising:
-
coupling a liquid reservoir to a gas extraction device, the gas extraction device having a vent membrane configured to enable gas to pass through the vent membrane and prevent a fluid from passing through the vent membrane, the vent membrane comprising a fluid inlet aperture, a first adhesive layer coupled to the vent membrane and having a first channel formed therethrough, and an impermeable membrane coupled to the first adhesive layer opposite the vent membrane, wherein the first channel is in fluid communication with the fluid inlet aperture of the vent membrane; and channeling the liquid through the first channel in the first adhesive layer, said channeling the liquid causing the liquid to contact the vent membrane, wherein contacting the vent membrane causes the gas to move through the vent membrane. - View Dependent Claims (15, 16, 17, 18, 19, 20)
