4 results about "Coronary circulation" patented technology

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 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.

The invention provides a traditional Chinese medicine composition for treating diabetic nephropathy, a pharmaceutical preparation and a preparation method thereof, and belongs to the technical field of medicines. The traditional Chinese medicine composition comprises the following components: astragalus membranaceus, codonopsis pilosula, cassia twig, cistanche, dogwood, semen cuscutae, bighead atractylodes rhizome, rhizoma atractylodis, pericarpium citri reticulatae, poria cocos, rhizoma alismatis, yam rhizome, corydalis tuber and caulis spatholobi. The traditional Chinese medicine composition and the pharmaceutical preparation provided by the invention have the effects of invigorating spleen and tonifying kidney, warming phlegm and fluid retention, and promoting blood circulation and promoting coronary circulation, and have a good treatment effect on diabetic nephropathy.
