An apparatus is provided to generate a gas by mixing chemicals with water. Typically, the production of gas, particularly oxygen, by combining water with powders and other dry chemicals has not been widely employed. There have existed a number of preexisting barriers such as undesirable flow rates and yields. However, by utilizing multiple reaction chambers the flow rates and yields can be more precisely tailored for a variety of situations that may call for particular flow rates and yields. Additionally, the use of the dry chemicals would allow for a long self-life allowing the apparatus to be particularly useful in emergency situations.

Method for controlled production of a gas

Disclosed is a device for isolating a cardiac surgical site. The device comprises a first finger having a clinging accessory for attaching the first finger to a heart, a second finger having a clinging accessory for attaching the second finger to the heart, a first joint disposed on the first finger so that the first finger may rotate on a surface of the heart such that said rotation stretches a surgical site, a first stopper disposed on the first finger for preventing undesired rotation of the first finger to isolate the surgical site, and a link for coupling the first finger to the second finger. Several embodiments of the fingers and clinging accessories are disclosed. A guard is provided to protect sutures from the clinging accessory. The guard is equipped with a sprayer to wash the surgical site. Also disclosed is a method of isolating a cardiac surgical site. The method comprises the steps of disposing a first finder on a heart, clinging the first finger to the heart surface, disposing a second finger on a heart, clinging the second finger to the heart surface, and then rotating the first finger for achieving selective isolation of the heart surface.
