Abstract

Example defibrillator electrode assemblies compression assemblies are described that may be dimensioned and configured for use on a patient despite physical constraints that limit the area or locations on a patient onto which an electrode assembly may be placed. A cardio pulmonary resuscitation (CPR) assembly is also described that protects a patient with a transthoracic incision from further injury during application of CPR compressions proximate to the incision.

First claim

What is claimed is:

1 . A medical assembly for use in providing resuscitative treatment to a patient, comprising:
a first therapy pad comprising a first non-conductive substrate and a first electrically conductive layer in contact with the first non-conductive substrate; a second therapy pad comprising a second non-conductive substrate and a second electrically conductive layer in contact with the second non-conductive substrate; a third therapy pad comprising a third non-conductive substrate and a third electrically conductive layer in contact with the third non-conductive substrate; a chest compression sensor removably attached to a top surface of at least one of the first therapy pad, second therapy pad, or third therapy pad, the top surface being opposite from a bottom surface of the at least one of the first therapy pad, second therapy pad, or third therapy pad, the bottom surface being arranged to contact skin of the patient when in use; and a controller coupled to each of the first, second, and third therapy pads, the controller being configured to
initiate application of a first defibrillation current between the respective electrically conductive layers of at least two therapy pads of the first therapy pad, the second therapy pad, and the third therapy pad such that a first vector of current travel occurs between the at least two therapy pads, and
initiate application of a second defibrillation current between the respective electrically conductive layers of two or more therapy pads of the first therapy pad, the second therapy pad, and the third therapy pad such that a second vector of current travel different from the first vector of current travel occurs between the two or more therapy pads.

2 . The medical assembly of claim 1 , further comprising a sterile pouch defining a sterile space therein, wherein the chest compression sensor and the at least one of the first therapy pad, second therapy pad, or third therapy pad attached to the chest compression sensor are removably disposed within the sterile space of the sterile pouch.

3 . The medical assembly of claim 1 , wherein each of the first, second, and third therapy pads has a length to width aspect ratio of between 3:1 and 30:1.

4 . The medical assembly of claim 1 , wherein the chest compression sensor comprises at least one of an accelerometer and a gyroscope.

5 . The medical assembly of claim 1 , further comprising an electrical conductor connected to the chest compression sensor, the electrical conductor configured to transmit at least one of acceleration data and orientation data from the chest compression sensor to the controller.

6 . The medical assembly of claim 5 , wherein the electrical conductor has a coiled shape.

7 . The medical assembly of claim 5 , wherein the electrical conductor is coupled to the at least one of the first therapy pad, second therapy pad, or third therapy pad via a releasable connection.

8 . The medical assembly of claim 1 , further comprising a placement pad that encapsulates the chest compression sensor.

9 . The medical assembly of claim 8 , wherein the chest compression sensor is disposed within a center portion of the placement pad.

10 . The medical assembly of claim 1 , wherein the chest compression sensor is removably attached to at least one of the first non-conductive substrate, second non-conductive substrate, or third non-conductive substrate.

11 . The medical assembly of claim 1 , further comprising a fourth therapy pad comprising a fourth non-conductive substrate and a fourth electrically conductive layer in contact with the fourth non-conductive substrate.

12 . The medical assembly of claim 11 , wherein at least two or more of the first non-conductive substrate, second non-conductive substrate, third non-conductive substrate, and fourth non-conductive substrate are coupled together.

13 . The medical assembly of claim 11 , wherein two of the first, second, third, and fourth therapy pads are electrically connected together.

14 . The medical assembly of claim 11 , wherein each of the first, second, third, and fourth therapy pads is configured to be arranged on a separate location of the patient.

15 . The medical assembly of claim 1 , wherein the first therapy pad comprises a first adhesive layer, the second therapy pad comprises a second adhesive layer, and the third therapy pad comprises a third adhesive layer.

16 . The medical assembly of claim 15 , wherein each of the first, second, and third adhesive layers comprises a hypoallergenic medical grade acrylic material.

17 . The medical assembly of claim 15 , wherein the first therapy pad comprises a first release layer on the first adhesive layer, the second therapy pad comprises a second release layer on the second adhesive layer, and the third therapy pad comprises a third release layer on the third adhesive layer.

18 . The medical assembly of claim 17 , wherein each of the first, second, and third release layers comprises a polymeric sheet.

19 . The medical assembly of claim 1 , wherein each of the first, second, and third therapy pads has a length to width aspect ratio of between 5:1 and 20:1.

20 . The medical assembly of claim 1 , wherein each of the first, second, and third therapy pads is configured to be arranged on a separate location of the patient.
