本发明涉及医疗器械领域，特别是一种用于心脏复苏的按压装置。The invention relates to the field of medical equipment, in particular to a pressing device for cardiac resuscitation.
背景技术Background technique
心脏骤停发生后最主要的抢救措施是及时正确地进行心肺脑复苏。心肺脑复苏是针对心脏骤停，旨在尽快建立有效循环，提高心输出量，而采取的一系列措施。目前，市场上用于心脏复苏设备称为胸外心脏按压器，用于在患者外部实施心脏的按压，以便于心脏能够复苏。但对于一些开放性胸部创伤，或外伤并发多根多处肋骨骨折而出现心跳骤停时，胸外心脏按压将是禁忌。此时临床急诊抢救将需要进行开胸徒手心脏挤压，称胸内心脏按压。然而，徒手胸内心脏按压存在按压创口大、按压力度不均匀、且不能持续按压、不能维持较长时间等缺点。The most important rescue measure after cardiac arrest is timely and correct cardiopulmonary cerebral resuscitation. Cardiopulmonary cerebral resuscitation is a series of measures taken against sudden cardiac arrest, aiming to establish effective circulation as soon as possible and increase cardiac output. Currently, the cardiac resuscitation equipment on the market is called an external cardiac compressor, which is used to compress the heart outside the patient so that the heart can be resuscitated. However, for some open chest trauma, or trauma complicated by multiple rib fractures and cardiac arrest, external cardiac compression will be contraindicated. At this time, clinical emergency rescue will need to perform thoracotomy and freehand heart compression, which is called intrathoracic cardiac compression. However, manual chest cardiac compression has disadvantages such as large compression wound, uneven compression force, inability to continue compression, and inability to maintain for a long time.
