Ultrasonic Spray Coating for Medical
The medical industry is one of the earliest fields where ultrasound spraying entered, and it is used for spraying medical implant devices such as heart stents, catheters, and protective equipment. There are many advantages to the application of ultrasonic spraying in the fields of drugs and medical devices. It can help improve drug release efficiency, enhance the performance and functionality of medical devices, and achieve high-quality coating preparation.
Drug Eluting Stent
In the preparation process of drug-eluting stents, ultrasonic spraying technology atomizes the drug solution into tiny droplets through the vibration of high-frequency sound waves, while accurately controlling the spraying amount and position of the drug, thereby achieving uniform distribution of the drug on the surface of the stent.
Drug eluting stents, as an important treatment method, have been widely used in clinical treatment. In the preparation process of drug-eluting stents, ultrasonic spraying technology plays an increasingly important role.
Balloon Catheter
The ultrasonic balloon spray system is developed for coating implantable medical balloon catheters and is designed to spray anti-restenosis solutions containing drugs + plasticizers onto catheters equipped with cardiac angioplasty or other drug-coated medical balloons.
The special fixture design allows spraying of the entire balloon catheter, with a maximum effective spray length of up to 280mm, and has functions of solvent doping, preheating, humidity control and drying. The special fixture in the system can be removed or replaced to coat other medical devices, such as peripheral stents.
Blood Collection Tubes
The probe type ultrasonic nozzle is specially developed by FUNSONIC for spraying the inner wall of blood collection tubes or syringes. By extending the front end design of the nozzle, the ultrasonic nozzle can be sprayed deep into narrow spaces, making it particularly suitable for spraying on the inner walls of pipelines. Typical applications include vacuum blood collection tube spraying, injector silicone oil spraying, etc., which can evenly apply coagulation activators and anticoagulants, including heparin EDTA, Silicon dioxide and glucose citrate. At the same time, the atomized spray can be isolated to the wall of the bottom coating area required by the BCT or syringe cylinder, instead of coating the entire tube.
Biosensors/Diagnostic Devices
In the preparation of biosensors/diagnostic devices, ultrasonic spraying technology can accurately control droplet size and distribution, achieving uniform coating coverage. This technology performs well in protein detection, enzyme sensors, DNA sensors, and environmental pollutant monitoring. It can effectively improve the sensitivity and detection stability of sensors, extend their service life, and is suitable for rapid response biological detection applications.
It is mainly applied in Reagent coatings on microfluidics, Hydrophilic and hydrophobic coatings on microfluidics, Point-of-care diagnostics and test kits, Cell culture vessels, Glucose monitors, Blood collection and analysis devices, Molecular and protein diagnostic kits, Immunoassay kits and so on.
Medical Textiles
FUNSONIC's ultrasonic medical coating systems have been used to apply a variety of antimicrobial or other medical bandage coatings to topical wound care and dressings as well as implantable wound dressings, hemostatic patches and soft tissue repair devices, ranging from small, selective spray areas and thin lines to wide fabrics.
Coatings such as coagulants, antimicrobials, antiseptics, antibiotics and other drugs can be applied to topical and implantable dressings and devices to help minimize rejection, inflammation and infection, promote biocompatibility and rapid healing, relieve pain, or improve adhesion to the treatment site.
Application: Colloidal silver, Thrombin, Steroids, Titanium Dioxide, Acetaminophen, Anesthetics, Omega-3 fatty acids, Antibacterial Peptides and Enzymes (Lysostaphin), NSAIDS (Ibuprofen, Naproxen), Antimicrobial etc
