Apparatus and method for producing an enriched medical suspension of carbon dioxide
A medical fluid suspension generating apparatus for performing medical procedures includes a Venturi-agitating tip assembly composed of a multi-channel arrangement at a proximal first end thereof and a tip at a distal second end thereof. The apparatus also includes a compressed medical fluid unit fluidly connected to the multi-channel arrangement at a proximal first end of the Venturi-agitating tip assembly and a medical solution fluidly connected to the multi-channel arrangement at a proximal first end of the Venturi-agitating tip assembly. Pressurized gas, from the compressed medical fluid unit, and the medical solution are combined within the Venturi-agitating tip assembly in a manner generating an enriched medical suspension that is ultimately dispensed from the suspension delivery apparatus.
1. An apparatus for creation and delivery of enriched medical suspension, comprising:
a compressed medical fluid unit containing pressurized medical carbon dioxide (CO 2 );
