The present application relates to a TAVR teaching model based on blood flow simulation and multi-modal image fusion and use method. The model comprises a simulated thoracic and abdominal cavity with a built-in heart wave beat simulation part that drives fluid to generate pulsatile blood flow, a simulated thoracic and abdominal body with pre-set vascular access, a bionic heart assembly with structures such as a ventricular cavity, a pathological valve module that can be detachably fitted to the aortic valve ring and contains a pressure sensor array and simulated calcification, a coronary circulation monitoring module that monitors the perfusion state of the coronary artery opening, a virtual fluoroscopy positioning module that generates real-time fluoroscopy images, and a central control console that electrically cooperates with each module. The scheme simulates the tactile sensation of calcification through the pathological valve module, the heart wave beat simulation part reproduces the physiological pressure difference with a closed loop blood flow, realizes image navigation training with non-radiation virtual fluoroscopy, integrates real-time simulation of complications with coronary monitoring and annulus pressure sensing, and solves the problems of existing models such as distorted hand feeling, inaccurate dynamics, dependence on radiation, and lack of complication training.

The present invention relates to the field of ultrasounds and imagining of the coronary blood flow of the heart. Patients with coronary microvascular dysfunction (CMD) have poor prognostic with significantly higher rates of cardiovascular events, including hospitalization for heart failure, sudden cardiac death, and myocardial infarction (MI). Despite the urgent clinical need, there are no non-ionizing and non-invasive techniques available in clinic to directly visualize the coronary microvasculature and assess the local coronary microvascular system. Flow imaging remains a difficult task to perform in the heart because of the fast movements of this organ. In order to overcome the limitations of actual imaging methods for the coronary blood flow, the inventors proposed an ultrasound ultrafast imaging method that automatically detect the time periods in which the myocardium velocity is low and estimate the coronary flow velocity and the tissue velocity from the same data acquisition.

The invention belongs to the technical field of traditional Chinese medicine, and particularly relates to a compound traditional Chinese medicine composition for improving cerebral ischemia-reperfusion nerve injury and application. The compound traditional Chinese medicine composition is prepared from the following raw materials in parts by weight: 288 to 435 parts of radix astragali seu hedysari, 120 to 180 parts of radix angelicae sinensis, 80 to 120 parts of rhizoma chuanxiong, 80 to 120 parts of radix paeoniae rubra, 80 to 120 parts of semen persicae, 80 to 120 parts of flos carthami, 80 to 120 parts of pericarpium citri reticulatae, 80 to 120 parts of rhizoma atractylodis macrocephalae, 80 to 120 parts of radix codonopsis, 80 to 120 parts of poria cocos, 32 to 48 parts of centipede, 80 to 120 parts of earthworm, 80 to 120 parts of bombyx batryticatus and 48 to 72 parts of liquorice root. The traditional Chinese medicine composition has the advantages that the traditional Chinese medicine composition is mainly used for tonifying qi and promoting blood circulation to jointly achieve the effects of regulating qi and promoting blood circulation, and dispersing blood stasis and promoting coronary circulation, is reasonable in formula compatibility, is mutually associated, is scientifically prepared, has very good beneficial technical effects through experiments, and has a remarkable effect of improving cerebral ischemia-reperfusion nerve injury.

The invention discloses a traditional Chinese medicine composition with the effects of promoting qi circulation, relieving pain, warming yang, activating blood and promoting coronary circulation. The traditional Chinese medicine composition is prepared from the following raw material medicines in parts by weight: 40-80 parts of peach kernel, 40-80 parts of safflower, 58-86 parts of rhizoma pinellinae praeparata, 72-108 parts of tangerine, 72-108 parts of vinegar-processed rhizoma corydalis, 72-108 parts of angelica sinensis, 72-108 parts of salvia miltiorrhiza, 40-80 parts of rhizoma cyperi, 72-108 parts of poria cocos, 120-180 parts of radix astragali preparata and 29-43 parts of radix glycyrrhizae preparata. Clinical results show that the composition has a remarkable curative effect on internal carotid plaque formation (traditional Chinese medicine symptoms) and is high in total effective rate.
