A system applies cardiopulmonary resuscitation (CPR) to a recipient. An automated controller is provided together with a compression device which periodically applies a force to a recipient's thorax under control of the automated controller. A band is adapted to be placed around a portion of the torso of the recipient corresponding to the recipient's thorax. A driver mechanism shortens and lengthens the circumference of the band. By shortening the circumference of the band, radial forces are created acting on at least lateral and anterior portions of the thorax. A translating mechanism may be. provided for translating the radial forces to increase the concentration of anterior radial forces acting on the anterior portion of the thorax. The driver mechanism may comprise a tension device for applying a circumference tensile force to the band. The driver mechanism may comprise an electric motor, a pneumatic linear actuator, or a contracting mechanism defining certain portions of the circumference of the band. The contracting mechanism may comprise plural fluid-receiving cells linked together along the circumference of the band. The width of each of the fluid-receiving cells becomes smaller as each cell is filled with a fluid. This causes the contraction of the band and a resulting shortening of the circumference of the band.

A chest press exercise machine has a self-aligning pivoting user support on a main frame and an exercise arm which is linked to the pivoting user support to translate movement of the exercise arm into movement of the user support. A user support pivot pivotally connects the user support to the main frame.

A connecting link is movably associated with the user engagement device or exercise arm and at least one of the main frame, user support, or user support pivot. The user support pivot is positioned so that part of the combined weight of the user and user support is positioned on both sides of the gravitational centerline throughout the exercise movement and a portion of the combined weight passes through the centerline to redistribute the weight as the exercise arm is moved.

A positioning device for use in apparatus for treating sudden cardiac arrest in a patient in supine position by providing chest compressions at the lower end of the sternum prevents the apparatus from moving in a caudal direction. The apparatus includes a frame enclosing the patient at a sternal transversal plane and a pneumatic compression / decompression unit mounted on the frame. The device includes a flexible strap having a first end, a second end and a tensioning component disposed between the first and second ends. First and second end portions of the strap include a mechanism for attachment to the apparatus. The flexible strap has a mounted tensioned length sufficient to extend around the patient's neck. At least one of the end portions is releasably attached.

An improved press arm allows an operator to perform either a traditional straight chest press exercise or to incorporate “butterfly” motion during the performance of the chest press exercise. A main arm is pivotally coupled to the frame of the exercise machine at a main pivot in the same manner as conventional press arms. The main arm includes a cross-beam to which a pair of handle arms are pivotally coupled at secondary pivots. The axes of the secondary pivots are orthogonal to the axis of the main pivot and are inclined with respect to vertical when the press arm is in a rest position. This inclination causes the handle arms to assume a natural rest position under the influence of gravity. The rest positions of the handle arms place the press arm handles at a comfortable starting position for performance of a press exercise. Stops to limit the inward or outward travel of the handle arms are not necessary. A source of exercise resistance resists both forward motion of the press arm assembly and inward motion of the handle arms.

A portable mechanical device to assist in external chest compressions during cardio-pulmonary resuscitative procedures. The embodiment consists of a frame (100), a plunger unit (104) and an articulating lever (109). The bottom member (102) of the frame is positioned under the subject such that the dome of the plunger unit (104) rests above the mid-sternal region. The handle (108) at the free end of the lever is used to apply downward force by the life-saver to provide the necessary chest compressions. The device is light in weight, easily transportable, and has an indefinite shelf life. This device is designed to be used by anyone with a basic training in CPR. The portability of the device renders itself useful outside the environs of a hospital, in confined quarters, and at remote locations.

One end of each leaf spring is operably connected to the piston and the other end of each leaf spring is secured to the backboard / base or to a support leg of the chest compression device such that during extension of the piston, each leaf spring is compressed against the device base or leg which causes the springs to flex and provide lateral compression of the patient's thorax in addition to the sternal compression of the piston.

The invention is an apparatus for increasing intrathoracic pressure for resuscitating cardiac arrest patients. The apparatus comprises a flexible, substantially inelastic belt wrapped around the patient's chest and attached to a force converter. The force converter converts a downwardly directed force into a chestward resultant, which depresses the sternum, and two belt tightening resultants. The force converter comprises a pair of arm assemblies, each having a pair of spaced arms, which are pivotably mounted to a base. The base is positioned near the patient's sternum and the ends of the belt attach to one end of each arm assembly. The opposite, handle ends of the arm assemblies are depressed toward the chest causing tightening of the belt and compression of the chest cavity.

The invention discloses a cardio-pulmonary resuscitation pressing depth indicating system with double sensors. The system comprises the first acceleration sensor arranged at the front chest pressing position of a human body, and the second acceleration sensor arranged at the position, directly facing the front chest pressing point, of the back of the human body. The first acceleration sensor transfers numerical values induced by the first acceleration sensor to a first microprocessor to calculate a first pressing displacement value. The second acceleration sensor transfers numerical values induced by the second acceleration sensor to a second microprocessor to calculate a second pressing displacement value. The first pressing displacement value and the second pressing displacement value are transferred to a third microprocessor on a display device in a wireless or wired mode. The third microprocessor enables a difference value of the first pressing displacement value and the second pressing displacement value to be displayed on a display screen. The cardio-pulmonary resuscitation pressing depth indicating system can detect the true chest pressing depth accurately, improve the first-aid quality and display the pressing depth to a rescuer in real time for reference.
