Ultrasonic Medical Spraying Machine for Anti Restenosis Polymers or Plasticizers onto Implantable Balloon Catheters

Description:

The ultrasonic medical stent coating machine is an ultrasonic spraying machine suitable for spraying anti restenosis polymers or plasticizers onto implantable balloon catheters. Mainly including X+U-axis precision motion module, equipped with a comprehensive program editing system, equipped with ultrasonic nozzles produced by Fansuo Energy, and equipped with precision constant flow injection pump, digital carrier gas system, optional ultrasonic dispersion liquid supply system, heating and other functions.
The entire equipment has a simple and elegant structure, complete functions, and is developed for enterprises, universities, and research institutes that use ultrasonic spraying equipment to produce bracket products. The X-axis controls the horizontal movement of the ultrasound nozzle in the X-direction, with an adjustment accuracy of up to 0.01mm. The U-axis drives the stent to rotate 360 ° to evenly distribute micrometer sized droplets after ultrasound atomization onto the vascular stent. A high-precision constant flow injection pump is used to control the liquid flow rate, making the coating thickness precise and controllable.

Advantages of ultrasonic spraying system for bracket coating:

1. Strong controllability and repeatable coating
2. The ultrasonic nozzle technology is mature and there will be no blockage phenomenon
3. Able to spray at an extremely low flow rate of microliters per minute
When using organic solvents, the droplet size is as small as 9 microns, and the spray particle size distribution is very uniform and compact
5. The spray deposits gently and slowly on the support, without rebound or splash
6. The coating is durable and will not peel off

General configuration:

1. Viscosity and solid content: Typically, viscosity ≤ 30cps, and suspension requires a solid content not exceeding 20-30%
2. Liquid supply equipment: precision injection pump+biological grade sampler, with a liquid supply accuracy of 0.1uL/min
3. Dry film thickness: 20nm-100um (related to the substrate of the solution)
4. Input voltage: 220V ± 10%, 50-60Hz
5. Solution conversion rate: ≥ 95%, utilization rate several times that of traditional two fluid pneumatic nozzles
6. Atomized particle size: average 15-45 μ m. It mainly depends on the frequency of the nozzle, and the higher the frequency, the smaller the particle size
7. Spray nozzle frequency: can be equipped with various spray nozzle systems ranging from 30-200KHz

Optional configuration:

1. Ultrasonic dispersion liquid supply system: It can continuously disperse and stir nanoparticles during the spraying process, effectively reducing the precipitation phenomenon of the spraying liquid and greatly improving the uniformity of the film layer
2. Heating and drying platform: using aviation aluminum porous platform or precision micro porous ceramic platform, with precise temperature control of 200 ℃
3. Vacuum adsorption platform: equipped with a multi-channel vacuum generator that can be controlled by zones, accurately adsorbing the thin film substrate without deformation.
4. Spray nozzle alignment device: Laser alignment is used.
5. We can also customize other configurations that you need!
