Problems solved by technology

Although the method has been proven to save lives, it has disadvantages, primarily the inability to control the force of the blow in a repeatable manner
Thumping too hard may result in bodily injury, while thumping too lightly may be ineffective

Embodiment Construction

[0032] The present invention provides a mechanical defibrillator configured to deliver a predetermined mechanical shock and regenerative energy to the chest of a cardiac arrest patient. The device includes a shock element mounted on a frame configured to be placed on a patient's chest. Shock elements onto renewable energy storage elements. A controllable means of releasing energy stored in the energy storage element allows the shock element to be triggered to deliver a blow of predetermined energy to the patient's chest. Preferably, the energy storage element is manually loaded prior to applying the blow. The defibrillator of the present invention can be designed to deliver a thump of a preset fixed force, or it can be designed to allow the thump force to be adjusted within a predetermined range. Preferably, the striking force is at most 180Kg, more preferably, the force is in the range of 60-160Kg, and the impact time is about 10-50 milliseconds.

Abstract

A mechanical defibrillator comprising an impact member configured to deliver a mechanical impact of a preset force to the chest of a subject in need of a defibrillation shock.

Description

technical field [0001] The present invention relates to portable defibrillators, and more particularly, to portable reloadable mechanical defibrillators that use stored mechanical energy to deliver a mechanical defibrillating shock to a patient's chest. Background technique [0002] One of the leading causes of cardiac arrest is ventricular fibrillation (VF), which occurs when the heart's electrical systems short circuit, causing the heart to quiver faster than its normal rhythm of pumping. Since blood can no longer be pumped effectively, if a normal heart rhythm is not restored within minutes, serious brain damage and even death can result. There are many causes of VF, including birth defects, disease, myocardial infarction, and environmental conditions. Although older people are more prone to VF, it can also occur in younger athletes due to intense panting of the chest. This phenomenon, called heart oscillations, affects young people who have not had heart disease. The ...
