Ultrasonic Spraying of Rapamycin Rapamycin (RAPA) is a new macrolide immunosuppressant. It is a white solid crystal with a melting point of 183-185°C. It is lipophilic and soluble in methanol, ethanol, acetone, chloroform and other organic solvents. Dissolved in water. Source of rapamycin: Rapamycin (also known as "Sirolimus") is a secondary metabolite secreted by soil Streptomyces first discovered by scientists in the soil of Easter Island, Chile in [...]

Ultrasonic Spraying Hydrophilic Coating Ultrasonic Spraying Hydrophilic Coating - Cheersonic Molecules with polar groups have great affinity for water and can attract water molecules or dissolve in water. The surfaces of solid materials formed by such molecules are easily wetted by water. Having this characteristic is the hydrophilicity of the substance. Hydrophilicity refers to the physical property of molecules capable of forming transient bonds with water through hydrogen [...]

Hemodialyzer Dialysis Membrane Hemodialyzer Dialysis Membrane - Thin Film Functional Coatings - Cheersonic "Hemodialysis is the use of artificial kidneys, mainly including dialysis membranes and dialysis machines, to remove excess water and toxins in patients with renal failure, and to correct electrolyte and acid-base disorders. The dialysis membrane is the key to the dialyzer, and the dialysis membrane is a semi-permeable membrane. , allowing water and small molecular [...]

Introduction to Prosthetic Heart Valves Introduction to Prosthetic Heart Valves - Heart Valves Coating - Cheersonic The development history and trend of artificial heart valve: mechanical valve→biological valve→interventional valve. Four heart valves: aortic valve, pulmonary valve, mitral valve, and tricuspid valve; the English abbreviations are: APMT, and the difficulty of research and development and the order of products are also: A→P→M→T Heart valve surgery is divided into: open [...]

Types of Cardiac Occluders Types of Cardiac Occluders - Ultrasonic Spraying Cardiac Occluder - Cheersonic Cardiac occluders can be broadly classified into atrial septal defect occluders, ventricular septal defect occluders, patent ductus arteriosus occluders, etc. 1. Atrial septal defect occluder: Statistics show that the average incidence of congenital heart defects reported by different studies is 1 to 8 per 1,000 live births. An atrial septal defect (ASD) is [...]

Heart Valve Device Heart Valve Device - Preparation of Film Coatings For Heart Valves - Cheersonic There are four heart valves in the human body, namely the mitral valve, tricuspid valve, aortic valve and pulmonary valve. The mitral and tricuspid valves control blood flow between the chambers of the heart, the aortic valve controls blood flow from the blood to various organs throughout the body, and the pulmonary [...]

What types of cerebrovascular stents are there? What types of cerebrovascular stents are there? Stent Coater - Cheersonic Cerebrovascular disease is the leading cause of death and disability among Chinese residents. Like cardiovascular diseases, stents are our main weapon in the treatment of cerebrovascular diseases. But unlike cardiac coronary stents, there are many types of cerebrovascular stents. Today I will introduce to you a wide variety of cerebrovascular [...]

What is carotid artery stent implantation? What is carotid artery stent implantation? Intracranial Stent Coater - Cheersonic The carotid artery is one of the blood vessels most prone to stenosis. Blockage will cause severe cerebral vascular acute thrombosis, hemiplegia, coma, and even life-threatening situations, with high disability and fatality rates, which should be paid close attention to. Currently, vascular imaging methods mainly used in carotid arteries include: carotid [...]

Stenotic and Dilatable Drug-coated Intracranial Stents Stenotic and Dilatable Drug-coated Intracranial Stents - Stent Coating - Cheersonic Intracranial atherosclerotic disease remains the most common cause of ischemic stroke and one of the leading causes of ischemic stroke in Asian populations. Intracranial atherosclerotic disease has a high disability and mortality rate, and even intensive drug treatment may lead to vascular stroke or cerebrovascular death. Endovascular treatment of intracranial atherosclerotic [...]
