Medical Coating

Bioceramics Bioceramics refers to a type of ceramic materials used for specific biological or physiological functions, that is, ceramic materials that are directly used in the human body or directly related to the human body, such as biology, medicine, and biochemistry. As a bioceramic material, it needs to have the following conditions: biocompatibility, mechanical compatibility, excellent affinity with biological tissues, anti-thrombotic, sterilization and good physical and chemical stability. Bioceramic materials can be divided into biologically inert ceramics (such as Al2O3, ZrO2, etc.) and biologically active ceramics (such as dense hydroxyapatite, bioactive glass, etc.). 01— Biologically inert ceramics — Bio-inert ceramics mainly refer to ceramic materials with stable chemical properties and good biological compatibility. Such as alumina, zirconia and medical carbon materials. The structure of this kind of ceramic materials is relatively stable, the bonding force in the molecule ...

Ultrasonic Proteinase Reagent Coating Preservatives and proteins such as enzymes or antibodies are commonly used to coat medical or forensic diagnostic devices and substrates of various geometries, such as slides, tubes and well plates. These devices are used for humoral chemical testing and immunoassays to detect specific chemical or biological agents in a sample for disease detection and diagnosis. These devices are used in medical laboratories and facilities, even in the home (in the case of blood glucose monitoring or home pre-testing). Ultrasonic nozzles allow the development of such equipment and the expansion of its production. The CHEERSONIC ultrasonic system allows for repeatability and precision of coatings on a variety of substrates and geometries with minimal overspray to minimize waste.

Ultrasonic Stent Spraying Machine Our ultrasonic stent coating system can be used to spray antirestenotic drug-eluting polymer solutions onto implantable stents. We have expertise in spraying hundreds of different medical grade polymer chemicals. Ultrasonic nozzles have the advantage of spraying complex stent geometries, ensuring that all strut surfaces of the stent are covered. The gentle atomized spray can adhere well to the surface, and the morphological characteristics of the coating can be adjusted by modifying the process parameters. High-pressure nozzles cannot apply coatings as uniformly as ultrasonic coating systems. Compared to dip coating, the coating applied using ultrasound is thinner and saves spraying material. The ultrasonic nozzle is hardly clogged and the spray quality does not decrease with time. Advantages of ultrasonic stent coating: • Highly controlled and repeatable spray spray. • Non-blocking ultrasound technology. • Spray at a flow rate of microliters per hour....

 What should I pay attention to after placing the stent on the heart? Coronary artery is the general name of the main blood vessels that supply blood to the heart. If atherosclerosis occurs in the coronary arteries, the stenosis of the arterial blood vessels is found to be more than 50%, which has already affected the blood supply to the heart. It can be definitely diagnosed as coronary heart disease . Coronary heart disease is the general term for coronary atherosclerotic cardiovascular disease, whether it is coronary heart disease with stable angina pectoris after labor only, or acute thrombosis of the artery (myocardial infarction), or heart failure caused by coronary heart disease , Both belong to the scope of coronary heart disease. The question of whether a stent needs to be placed on the heart should be actively evaluated and confirmed. In the case of acute myocardial infarction, in order to open up the blocked blood vessels and improve blood flow as soon as possible, as lon...

Does the heart stent have a life span? Coronary heart disease is the appearance of plaque in the coronary arteries, which narrows the lumen of the blood vessels, resulting in myocardial ischemia and chest pain. When performing cardiac stent surgery, first use a balloon catheter to expand, flatten the plaque in the blood vessel, and expand the blood vessel at the same time. Then the heart stent is placed. The stent will stick the plaque to the wall of the blood vessel and maintain the size of the blood vessel cavity to prevent the blood vessel from narrowing again due to elastic retraction. The stent and the vascular intima are tightly combined. Subsequently, the endothelial cells on the intima of the blood vessel will slowly grow and gradually cover the stent trabeculae. Eventually, the stent is integrated with the vessel wall. Therefore, there is no such thing as a "lifespan" for heart stents, and heart stents do not need to be replaced every few years. This is a big misunde...

Stent Coating System benchtop stent coating system standalone stent coating system The UAM3000 is a new stent coating system for coating arterial stents with polymers containing anti-restinosis drugs. The UAM3000 offers the same cutting-edge precision stent coating features that have made Cheersonic the industry's manufacturer in producing high-quality stent coatings with expanded features and higher volume production capabilities. The system incorporates Cheersonic's ultrasonic nozzle, which produces a very thin, precise, straight spray pattern, and ultra-low liquid delivery system. Customers have the option of attaching a custom stent holding device onto the rotating mandrels or using Cheersonic provided mandrels. The stents are loaded onto the mandrels and the cassette is inserted into the load chamber. The extend/retract shaft picks up each stent from the cassette and delivers it to the sealed process chamber for spraying. Stents are rotated at a fixed speed, controlled by...
