Abstract
A urinary drainage system is disclosed herein. The urinary drainage system can include an air pressure apparatus with a connector having an elongate connector body. The connector includes a lumen having a larger proximal lumen diameter and a smaller distal lumen diameter. The system includes an air intake adapter having an elongate adapter body, including a proximal end having a proximal opening configured to be coupled to the distal end of the connector. The adapter can include an air intake port in fluid communication with the adapter lumen, the adapter lumen having a larger proximal lumen diameter and a smaller distal lumen diameter.
Claims25
A urinary drainage system, comprising:
- an air pressure apparatus, comprising:
- a connector having a connector body defining a connector lumen extending along a longitudinal axis between a proximal opening and a distal opening of the connector, the proximal opening of the connector in fluid communication with a catheter;
- and
- an adapter comprising:
- an adapter body defining an adapter lumen extending along the longitudinal axis, the adapter lumen including a proximal end having a proximal opening configured to engage the connector body at a point proximal of the distal opening of the connector, wherein:
- the adapter lumen is in fluid communication with the connector lumen when the proximal opening of the adapter lumen is engaged with the connector body, and
- a lumen diameter of the proximal opening of the adapter lumen is larger than an outer diameter of the distal opening of the connector;
- an air intake port extending perpendicular to the longitudinal axis and in fluid communication with the adapter lumen, the air intake port configured to provide a positive air flow to the adapter lumen proximally of the distal opening of the connector and to draw a fluid flow distally through the distal opening of the connector;
- and
- a luminal space defined by an inner wall of the adapter lumen and an outer surface of the connector adjacent the distal opening of the connecter and extending annularly about a distal portion of the connector, the luminal space in fluid communication with the air intake port.
A method for clearing a fluid from a catheter, comprising:
- coupling an air pressure apparatus to a distal end of the catheter and coupling a fluid collecting bag to a proximal end of the air pressure apparatus, the air pressure apparatus having a connector disposed proximally and defining a connector lumen extending between a proximal opening and a distal opening and an adapter disposed distally and defining an adapter lumen, the adapter engaging the connector at a point proximally of the distal opening of the connector to define a luminal space therebetween;
- passing an acquired volume of fluid from the catheter to the fluid collecting bag;
- providing a positive air pressure into the luminal space of the adapter by way of an air intake port;
- and
- drawing a fluid flow through the distal opening of the connector to clear the catheter of a residual volume of fluid.
