Why are vacuum blood collection tubes and syringes sprayed with coatings on their inner walls?

In the process of modern medical diagnosis and treatment, vacuum blood collection tubes and syringes are indispensable basic medical devices. From the collection and preservation of patient blood samples to the precise injection of drugs, every link is related to the accuracy and safety of medical results. The inner wall of the seemingly ordinary vacuum blood collection tube and syringe actually hides a mystery - the application of spray coating plays a vital role in improving its performance.

With the continuous advancement of medical technology, the performance requirements for vacuum blood collection tubes and syringes are becoming increasingly stringent. The development and application of spray coating technology not only improves the quality and function of medical devices, but also lays the foundation for the safety and efficiency of the medical industry.

● Vacuum blood collection tube inner wall coating: siliconized coating, procoagulant and anticoagulant coating

● Syringe inner wall coating: lubricant coating, anti-corrosion coating

Ultrasonic spraying technology is a coating preparation method. Compared with traditional spraying technology:

●Good coating uniformity: Ultrasonic spraying uses high-frequency vibration to form tiny droplets of coating, which can be more evenly distributed on the inner wall of blood collection tubes or syringes, reduce coating thickness differences and local defects, and improve coating quality and performance consistency.

●Precise coating thickness control: The coating thickness can be precisely controlled by accurately controlling parameters such as ultrasonic power, spraying time and coating flow rate, meeting the strict requirements of coating thickness in different application scenarios.

●High material utilization rate: Ultrasonic spraying has good atomization effect, and the coating particles are small and uniform, which can better adhere to the surface of the object, reduce paint splashing and waste, improve material utilization rate, and reduce production costs.

●Little damage to the substrate: During the spraying process, the vibration energy generated by the ultrasonic wave mainly acts on the coating droplets, and the thermal impact and mechanical stress on the substrate material of the blood collection tube or syringe are small, which is conducive to maintaining the performance and dimensional accuracy of the substrate, especially suitable for heat-sensitive or high-precision medical device components.

●Good environmental protection: Due to the high utilization rate of paint, the waste and volatilization of paint are reduced, and the pollution to the environment is reduced. At the same time, ultrasonic spraying technology can use environmentally friendly paints such as water-based paints, further improving its environmental friendliness.
