Abstract

Examples of the disclosure are directed to adjustable back plates or backboards for a mechanical compression device to accommodate different patient sizes and/or for ease of storage. Examples of the disclosure includes back plates that can be folded, pieced together, or otherwise have a variable distance between connectors that attach to legs of a chest compression device. Examples also include back plates which may have two sides, such as an adult patient side and a pediatric patient side, to accommodate different patient sizes.

Claims (27)

1. A backboard for a chest compression device, the backboard comprising:

a chest compression member;

a backboard configured to interface with a support surface, the backboard comprising:

a first side structured to accommodate an adult-sized patient at a first distance from a support surface when attached to the chest compression device in a first orientation; and

a second side structured to accommodate a pediatric-sized patient at a second distance from the support surface when attached to the chest compression device in a second orientation, the second distance being greater than the first distance;

wherein the first side and the second side are separate, unitary structures, and wherein the first orientation corresponds to the second side interfacing with the support surface, and the second orientation correspond to the first side interfacing with the support surface; and

a controller configured to determine an identification of the backboard and adjust the chest compression member based on the identification, wherein the controller is configured to determine the identification of the backboard based on a characteristic of a first connector or a second connector.

2. The chest compression device of claim 1 , wherein the characteristic includes at least one of an angle of a leg of the chest compression device connected to a respective connector of the backboard or a size of an anchoring point of the respective connector.

3. The chest compression device of claim 1 , in which the first side of the backboard includes a first attachment point and a second attachment point, and in which the second side of the backboard includes a first attachment point and a second attachment point, wherein the first attachment point of the first side is structured to attach a first leg of the chest compression device to the backboard when in the first orientation, wherein the second attachment point of the first side is structured to attach a second leg of the chest compression device to the backboard when in the first orientation, wherein the first attachment point of the second side is structured to attach the first leg of the chest compression device to the backboard when in the second orientation, wherein the second attachment point of the second side is structured to attach the second leg of the chest compression device to the backboard when in the second orientation.

4. The chest compression device of claim 1 , wherein the second side of the backboard is configured to support the first side of the backboard at the first distance from the support surface when the first side is attached to the chest compression device in the first orientation, and wherein the first side is configured to support the second side at the second distance from the support surface when the second side is attached to the chest compression device in the second orientation.

5. The chest compression device of claim 1 , wherein the first side of the backboard has a curved portion with a first radius of curvature, and the second side of the backboard has a curved portion with a second radius of curvature that is different from the first radius of curvature.

6. The chest compression device of claim 1 , wherein the backboard is wedge-shaped, in which the first side has a first incline at a first inclination angle and the second side has a second incline at a second inclination angle, the second inclination angle being greater than the first inclination angle.

7. The chest compression device of claim 1 , wherein the first side is concave and the second side includes a flat section to accommodate the pediatric-sized patient.

8. A chest compression device, comprising:

a chest compression member;

a backboard configured to interface with a support surface, the backboard comprising:

a first side structured to accommodate an adult-sized patient at a first distance from a support surface when attached to the chest compression device in a first orientation, and

a second side structured to accommodate a pediatric-sized patient at a second distance from the support surface when attached to the chest compression device in a second orientation, the second distance being greater than the first distance;

wherein the first side and the second side are separate, unitary structures, and wherein the first orientation corresponds to the second side interfacing with the support surface, and the second orientation correspond to the first side interfacing with the support surface; and

a controller configured to determine an identification of the backboard and adjust the chest compression member based on the identification,

wherein the backboard includes a first identification component identifying the first orientation associated with the first side of the backboard and a second identification component identifying the second orientation associated with the backboard, and the controller is configured to received one of the first orientation or the second orientation from the backboard and control the chest compression member based on the received orientation,

wherein the first identification component is located in a first connector associated with the first side of the backboard, the first connector configured to attach to a leg of the chest compression device when the backboard is the first orientation, and wherein the second identification component is located in a second connector associated with the second side of the backboard, the second connector configured to attach to the leg of the chest compression device when the backboard is in the second orientation.

9. The chest compression device of claim 8 , in which the first side of the backboard includes a first attachment point and a second attachment point, and in which the second side of the backboard includes a first attachment point and a second attachment point, wherein the first attachment point of the first side is structured to attach a first leg of the chest compression device to the backboard when in the first orientation, wherein the second attachment point of the first side is structured to attach a second leg of the chest compression device to the backboard when in the first orientation, wherein the first attachment point of the second side is structured to attach the first leg of the chest compression device to the backboard when in the second orientation, wherein the second attachment point of the second side is structured to attach the second leg of the chest compression device to the backboard when in the second orientation.

10. The chest compression device of claim 8 , wherein the second side of the backboard is configured to support the first side of the backboard at the first distance from the support surface when the first side is attached to the chest compression device in the first orientation, and wherein the first side is configured to support the second side at the second distance from the support surface when the second side is attached to the chest compression device in the second orientation.

11. The chest compression device of claim 8 , wherein the first side of the backboard has a curved portion with a first radius of curvature, and the second side of the backboard has a curved portion with a second radius of curvature that is different from the first radius of curvature.

12. The chest compression device of claim 8 , wherein the backboard is wedge-shaped, in which the first side has a first incline at a first inclination angle and the second side has a second incline at a second inclination angle, the second inclination angle being greater than the first inclination angle.

13. The chest compression device of claim 8 , wherein the first side is concave and the second side includes a flat section to accommodate the pediatric-sized patient.
