Abstract
Abstract A disposable liquid entraining system includes a liquid container and a vapor generator. Initially, the container is sterilized and is filled with a sterile liquid. Then, the vapor generator is sterilized and is mounted within the container. The vapor generator receives a sterile, pressurized gas, and operates either as a humidifier or as a nebulizer to form a vapor from the liquid in the container. During use, the interior of the container remains sterile, so that any possibility of contamination of the vapor is eliminated. After use, both the liquid container and the vapor generator are discarded.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
123 words
In a disposable liquid entraining system, a liquid container including: a. a collapsible main portion for receiving a medically sterile liquid, and b. a vapor generator receiving port, and a vapor generator including: a. a member having first and second gas passageways extending through it to first and second gas outlets and having a liquid passageway extending through it from a liquid inlet to a liquid outlet positioned adjacent the second gas outlet, and b. means for mounting the member in said vapor generator receiving port with the first gas outlet and the liquid inlet positioned below the surface of the liquid in the liquid container and with the second gas outlet and the liquid outlet positioned above the surface of the liquid.
Claim 2
Dependent Claim
123 words
In a disposable liquid entraining system, a liquid container including: a. a collapsible main portion for receiving a medically sterile liquid, and b. a vapor generator receiving port, and a vapor generator including: a. a member having first and second gas passageways extending through it to first and second gas outlets and having a liquid passageway extending through it from a liquid inlet to a liquid outlet positioned adjacent the second gas outlet, and b. means for mounting the member in said vapor generator receiving port with the first gas outlet and the liquid inlet positioned below the surface of the liquid in the liquid container and with the second gas outlet and the liquid outlet positioned above the surface of the liquid.
Claim 3
Dependent Claim
27 words
The disposable liquid entraining system according to claim 1 further including means mounted on the member for generating bubbles from gas flowing through the first gas passageway.
Claim 4
Dependent Claim
