Pediatric multifunctional cardiac defibrillator for cardiac surgery

Abstract

The invention belongs to the technical field of cardiac defibrillation, and discloses a pediatric multifunctional cardiac defibrillator for cardiac surgery, which comprises a power supply module, an electrocardiogram acquisition module, a main control module, a cardiac imaging module, a voltage regulation and control module, an electric shock module, a defibrillation optimization module and a display module. According to the invention, the cardiac imaging module uses a large number of images of which the left ventricle positions are manually marked by doctors to train the deep convolutional neural network, and the obtained result is more robust and higher in operation efficiency compared with the traditional algorithm; a manual enhancement mode is adopted, so that an edge area is enhanced,and the segmentation effect is improved; meanwhile, evaluation selection and optimal design can be carried out from a large number of feasible ICD electrode configuration schemes for the individual patient through the defibrillation optimization module, and finally the defibrillation treatment effect of ICD implantation is improved.

Description

Technical field [0001] The invention belongs to the technical field of cardiac defibrillation, and in particular relates to a pediatric multifunctional cardiac defibrillation device for cardiac surgery. Background technique [0002] Defibrillation (Defibrillation) is the process of terminating atrial fibrillation (Ventricular Fibrillation, VF) with medical devices or specific drugs. In medicine, the term "defibrillation" usually specifically refers to the operation of a defibrillator to terminate atrial fibrillation by discharging the heart. The most commonly used and most effective method for general defibrillation is electrical defibrillation, which is listed as the highest recommended level by the Cardiopulmonary Resuscitation and Cardiovascular Emergency Guidelines. However, the existing pediatric multifunctional cardiac defibrillation devices used for cardiac surgery have low quality of heart images, and the segmentation effect is not ideal. The segmentation effect depends ...

AI Technical Summary

Problems solved by technology

[0003] To sum up, the problems existing in the existing technology are: the quality of cardiac images collected by the existing pediatric multifunctional cardiac surgery defibrillation device is not high, the segmentation effect is not ideal, and the segmentation effect depends on the initial image generated by the traditional algorithm. Level set, the accuracy rate is not high; at the same time, the defibrillation effect is poor
