Venturi Effect Mixing Catheter Apparatus and Methods of Using the Same

A method for introducing a solution into a body cavity comprising:

• a. providing a catheter apparatus comprising
• i. a hub having a proximal end portion and a distal end portion adapted for attachment to a catheter, a lumen having a constricted diameter extending between the hub proximal and distal end portions and an airflow passage in communication with a portion of the hub lumen having a constricted diameter;
• b. inserting a distal end portion of the catheter into a body cavity;
• c. flowing a solution through the hub lumen to generate a vacuum in the lumen,
• d. permitting air to flow through the airflow passage to mix with the solution flowing through the hub lumen to create an aerated mixture of air bubbles in solution;
• e. introducing the mixture of air bubbles in solution into the body cavity through the distal end portion of the catheter.

A method for delivering a solution into a body cavity comprising the steps of:

• a. positioning the distal end of a catheter into the body cavity of a patient;
• b. injecting the solution through the lumen of a hub that is disposed outside of a patient, wherein the hub lumen is in fluid communication with the catheter;
• c. applying the Venturi effect to the solution flowing through the hub lumen to create a vacuum, wherein the vacuum causes air to be automatically drawn into the hub lumen through an air intake line to create a mixture of air bubbles in the solution within the hub lumen;
• d. emitting the mixture of bubbles in solution out of the distal end of the catheter and into the body cavity.
