Abstract
The present invention is directed to devices and methods of using a surgical drain, and more particularly to a surgical drain having at least one sensor for monitoring and/or recording the condition of the anatomical site or fluid emitted from the site where the surgical drain is placed. The invention may also include modifications of the surgical drain to improve stabilization or immobilization in the proximity of the anatomical site to be monitored.
Claims14
A surgical drain comprising:
- an elongated conduit configured to be implanted in and to drain fluid from a body cavity, the elongated conduit including a first surface located on an outer side of the elongated conduit;
- a drain portion configured to rest against a substantial length of tissue within the body cavity;
- a plurality of drain holes spaced along substantially the entire length of the drain portion;
- and
- a first sensing system configured to sense a physiological property of tissue proximate to the first surface, the first sensing system including a component that is affixed to the conduit.

A surgical drain system comprising:
- an elongated conduit configured to be implanted in and to drain fluid from a body cavity, the elongated conduit including a first surface located on an outer side of the elongated conduit and a second surface located on an outer side of the elongated conduit;
- a first sensing system configured to sense a physiological property of tissue proximate to the first outer surface;
- a second sensing system configured to sense the same physiological property of tissue proximate to the second outer surface;
- and
- a processing system in communication with the first and second sensing system that compares a difference between the physiological property sensed by the first and second sensing systems.
