Intrathoracic cardiac compression device

Abstract

The invention discloses an intrathoracic cardiac compression device. The intrathoracic cardiac compression device comprises a positioning plate, an air sac and a gas transporting pipe, wherein a chestwall fixing part for positioning the positioning plate on the inner side of the left side chest wall of a human body is arranged on the positioning plate; the air sac is fixed on the inner side of the positioning plate and communicates with the gas transporting pipe; and the air sac is inflated through the gas transporting pipe to expand facing a left ventricle of the heart and gradually press the surface of the left ventricle. According to the intrathoracic cardiac compression device disclosed by the invention, avoiding influencing the development of normal functions of the heart is facilitated, and when the heart normally beats, the intrathoracic cardiac compression device cannot separate from the heart; when cardiac compression is needed, the air sac is inflated through the gas transporting pipe and gradually expands, in the expanding process, the air sac is gradually close to the left ventricle to form compression on the left ventricle, after compression achieves a certain degree,the air sac is deflated through the gas transporting pipe to be contracted, in the contracting process, the air sac gradually be away from the left ventricle, then the left ventricle returns, and thecirculation is performed, so that an intrathoracic cardiac compression measure in a certain frequency is formed.

Description

Technical field [0001] The present invention relates to the field of medical equipment, in particular to an intrathoracic heart compression device. Background technique [0002] Cardiopulmonary cerebral resuscitation is mainly a series of measures taken for cardiac arrest, aiming to establish effective circulation and increase cardiac output as soon as possible; patients after thoracotomy often also need cardiopulmonary cerebral resuscitation; currently, on the market The device used for cardiac resuscitation is generally an external chest heart press, which is used to perform heart compression outside the patient so that the heart can be resuscitated. However, due to the limitation of the sternum, the compression effect on the outside of the chest is not obvious. In addition, patients who have undergone heart surgery have poor stability of the sternum, and the compression effect is even less obvious. In addition, for some open chest traumas or concurrent traumas When multiple r...

Problems solved by technology

[0004] However, in the above-mentioned presser, the squeeze bag is positioned by wrapping the heart. This method actually has relatively large defects in clinical practice: first, the anatomical structure of the heart and its connection structure with other blood vessels make it unsuitable for use in Otherwise, it is easy to affect the normal function of the heart; secondly, when the heart beats, its contraction movement is retracted from the apex of the heart, so when the sleeve method is used, once the heart beats, the squeeze bag is easy to be broken due to loose fixation. The heart is detached, there is a possibility of failure of compression, and there is a great potential safety hazard
