The present invention provides an implantable cardiac compression device comprising: an inflatable cardiac compression jacket configured when inflated to directly compress a heart and assist in displacing blood therefrom, a channel that connects the inflatable cardiac compression jacket and an expandable fluid reservoir configured to contain a fluid when displaced compresses the inflatable cardiac compression jacket, and a fluid driver operably connected to the inflatable cardiac compression jacket and to the expandable fluid reservoir, wherein the fluid driver is configured to inflate the cardiac compression jacket and to deflate the expandable fluid reservoir during systole of the heart; said driver is further configured to deflate the cardiac compression jacket and to inflate the expandable fluid reservoir during diastole of the heart.

The invention discloses an intensive care device. The intensive care device comprises a supporting box, a heart rate detector is arranged on one side in the supporting box, a conduit is arranged on one side of the heart rate detector, one end of the conduit extends and penetrates through the outer side of the supporting box, a suction cup is arranged at the end, on the outer side of the supporting box, of the conduit, and a heart rate sensor is arranged on one side of the suction cup. The pulse of a patient can be detected through a pulse detection device, and thus detection is more convenient; the heart rate of the patient can be detected through the heart rate detector, and thus detection of the heart rate of the patient is more convenient; a timed respirator can be used in the process of rescuing the patient, and the patient can be rescued when an emergency occurs; first-aid treatment can be conducted on the patient through a cardiac compression device. The intensive care device is simple in structure and easy and convenient to operate, and can monitor the patient, rescue the patient more timely and care the patient more comprehensively.

The present invention provides devices and methods for monitoring performance of minimally invasive direct cardiac massage. In particular, the present invention provides devices and methods which greatly facilitate proper performance of minimally invasive direct cardiac compression. Devices according to the present invention may comprise a handle, having a proximal end and a distal end, a structure attached to a distal end of the handle adapted to contact the pericardium or other heart surface to compress the heart, and a force transducer coupled to the handle and / or the structure to produce a signal which corresponds to an amount of force applied through the handle to the heart. A signal processor receives the force transducer signal and produces an output corresponding to the applied force. A display receives the output of the signal processor and produces a human decipherable indication based on the applied force.

The present invention provides a combined direct cardiac compression and aortic counterpulsation device comprising: an inflatable direct cardiac compression jacket configured when inflated to directly compress a heart and assist in displacing blood therefrom, an aortic counterpulsation chamber configured when inflated to displace aortic volume for the purposes of causing a counterpulsation effect, and a driver operably connected to said inflatable direct cardiac compression jacket and to said aortic counterpulsation chamber, said driver is configured to inflate said direct cardiac compression jacket and to deflate said aortic counterpulsation chamber during systole of the heart; said driver is further configured to deflate said direct cardiac compression jacket and to inflate said aortic counterpulsation chamber during diastole of the heart.

Systems and methods of enhancing cardiopulmonary circulation in a subject during resuscitation are provided. A signal is received responsive to an induced heart compression that is applied to the subject, for example during ventricular fibrillation, an asystolic condition, or cardiac arrest. Responsive to receipt of the signal, a muscle distal subject's heart is electrically stimulated to contract and expel blood into the venous blood flow toward a heart of the subject.

A method and related apparatus for the minimally invasive implantation about a heart of at least a deployable device such as a heart assist device or cardiac compression device. The method comprises the steps of performing a left thoracotomy or subxiphoid incision; obtaining access to the pericardial sac; making a generally linear incision in the pericardial sac; positioning an assembly having an insertion aperture member with an upper ring and a lower ring or flange and insertion tube having therein a deployable device. The apparatus of the present invention includes an insertion aperture member having an upper ring and a lower ring or flange; and an insertion tube having therein a deployable device adapted to be deployed from the insertion tube inside the pericardial sac via a generally linear incision.

The invention discloses a first-aid cardiac compression device with uniform compression force for the cardiology department. The cardiac compression device comprises a flat plate and a compression block, wherein sliding blocks are slidably connected to the two sides of the top of the flat plate; lifting hydraulic cylinders are fixedly connected to the tops of the two sliding blocks; a U-shaped seat is fixedly connected between the top ends of the two lifting hydraulic cylinders; a sliding seat is slidably connected to the bottom of the inner wall of the U-shaped seat; a box body is fixedly connected to the bottom of the sliding seat; a fixing plate is fixedly connected between the top and the bottom of the inner wall of the box body; and a concentric-square-shaped frame is slidably connected to the front face of the fixing plate. The invention relates to the technical field of medical equipment. According to the first-aid cardiac compression device with the uniform compression force for the cardiology department, through cooperation of an adjustable-speed motor, a driving shaft, a missing gear and driving teeth, the concentric-square-shaped frame can be driven to reciprocate up anddown, the stable frequency can be kept to drive the compression block to conduct compression work, an operator does not need to conduct manual compression, uniform compression can be achieved, and the compression frequency can be freely adjusted, so that the compression effect is good.

The present invention provides methods, systems, kits, and devices that aid in the positioning of a direct cardiac compression device about the heart.
