Cardiopulmonary resuscitation device and method of use

A method of using a manual cardiopulmonary resuscitation device having a handle, a deformable housing having a plurality of pleats or folds and defining a cavity entirely filled with foam, and a bottom plate in contact with a patient, the method comprising:

• applying a first compression force to the handle;
• at least partially compressing the deformable housing;
• and
• applying a second compression force to the patient different from the first compression force,
• wherein the deformable housing is entirely filled with foam, and wherein at least partially compressing the deformable housing includes causing the foam to compress such that a compressive only force is applied to the patient.

A manual cardiopulmonary resuscitation device comprising:

• a handle defining an exhaust aperture therein;
• a deformable housing having an outer wall defining a cavity therein, the deformable housing having a plurality of pleats or folds, a first end, and a second end opposite the first end, wherein the first end is coupled to the handle, and wherein the cavity is in fluid communication with the outer atmosphere via the exhaust aperture;
• foam that fills the cavity;
• and
• a bottom plate coupled to the second end of the deformable housing, the bottom plate formed from a flexible material,
• wherein the deformable housing is configured to deform and apply a compressive only force when pressure is applied to the handle,
• wherein the foam entirely fills the deformable housing.

A manual cardiopulmonary resuscitation device kit comprising:

• a handle defining an exhaust aperture therein;
• a bottom plate including a silicone base configured to contact a patient's chest;
• and
• a deformable housing having a plurality of pleats or folds, a first end coupleable to the handle, and a second end coupleable to the bottom plate, and defining a cavity therein, the deformable housing being entirely filled with foam, and where the deformable housing is configured to deform from a first configuration to a second configuration when pressure is applied to the handle.
