Abstract
Disclosed herein are systems and methods for providing targeted temperature management (TTM) therapy to a patient. The TTM system can include multiple embodiments of a thermal pad including embodiments that are convertible from a first patient contact area to a second patient contact area. Embodiments of thermal pads can include pads that are expandable, extendable, and/or comprise attachable or removable portions. The TTM system can include embodiments where a second thermal pad is coupled to a first thermal pad.
Claims22
A medical pad for exchanging thermal energy between a targeted temperature management (TTM) fluid and a patient, the medical pad comprising:
- a fluid containing layer for containing the TTM fluid, the fluid containing layer configured for circulating the TTM fluid within the fluid containing layer;
- and
- a patient contact surface defining a patient contact area to facilitate thermal energy exchange with the patient, wherein:
- the patient contact area is convertible from a first patient contact area to a second patient contact area,
- the second patient contact area is different from the first patient contact area,
- the first patient contact area is converted to the second patient contact area when a removable portion having the patient contact area of the medical pad is separated from a remaining portion of the medical pad,
- the removable portion comprises a removable fluid containing layer,
- the remaining portion comprises a remaining fluid containing layer, and
- the medical pad comprises one or more fluid conduits extending between the remaining fluid containing layer and the removable fluid containing layer.
A method of providing a targeted temperature management (TTM) therapy to a patient, comprising:
- providing a TTM system comprising:
- a TTM module configured to provide a TTM fluid;
- a first thermal pad comprising:
- a fluid containing layer configured to receive the TTM fluid from the TTM module to facilitate thermal energy transfer between the TTM fluid and a patient;
- and
- a thermal conduction layer disposed on a bottom surface of the fluid containing layer;
- and
- a fold extending along a length of the first thermal pad, wherein:
- the fold defines a first portion of the first thermal pad and a second portion of the first thermal pad overlapping the first portion of the first thermal pad, and
- the first portion and the second portion face a same direction;
- and
- a fluid delivery line (FDL) extending between the TTM module and the first thermal pad, the FDL configured to provide TTM fluid flow between the TTM module and the first thermal pad, wherein:
- the first thermal pad further comprises a patient contact surface defining a patient contact area to facilitate thermal energy exchange with the patient,
- the patient contact area is convertible from a first patient contact area to a second patient contact area, and
- the second patient contact area is different from the first patient contact area;
- expanding the first thermal pad along a single dimension to convert the first patient contact area to the second patient contact area;
- applying the first thermal pad to the patient;
- and
- delivering the TTM fluid from the TTM module to the first thermal pad.
