What is the advantage of ultrasonic blood tube spray coating?

Ultrasonic blood collection tube spray coating system 

Ultrasonic blood collection tube atomization spraying: opening a new chapter in precision medicine in modern medical diagnosis, blood collection tubes are key tools for obtaining human blood samples. With the continuous advancement of medical technology, the performance requirements for blood collection tubes are becoming increasingly stringent. Ultrasonic blood collection tube atomization spraying technology came into being. With its unique advantages, it has brought revolutionary changes to the production and manufacturing of blood collection tubes, and has strongly promoted the development of precision medicine.

The core of ultrasonic blood collection tube atomization spraying technology is to use the high-frequency vibration of ultrasound. Through the ultrasonic generator, the signal is transmitted to the transducer, which converts electrical energy into mechanical energy, thereby triggering high-frequency vibration of the nozzle. When the spray liquid flows through the nozzle, it is efficiently dispersed into extremely small droplets under the action of high-frequency vibration. These tiny droplets are sprayed on the inner wall of the blood collection tube in a uniform and fine state, forming a thin and uniform coating. Compared with traditional spraying technology, ultrasonic atomization spraying can make the coating thickness more accurately controllable, usually accurate to the micron level, which is a precision that traditional technology cannot achieve.

Ultrasonic blood collection tube spray systems are specifically designed for applying blood collection tube coatings such as clot activators and anticoagulants. Ultrasonic technology provides excellent coating uniformity and repeatability. An example of a common ultrasonic spray application for blood collection tubes is spraying silica coatings to accelerate clotting. A silica slurry is sprayed onto the tube wall to form a uniform film of silica particles. Ultrasonic spray is beneficial in this specific application because the ultrasonic vibrations of the spray head break up any silica agglomerates, ensuring uniform coating on the tube wall. In addition, spray heads of different lengths can be configured, depending on the diameter and length of the tube.

The ultrasonic spray system evenly applies clot activators and anticoagulants including heparin, EDTA, silica, and acid citrate dextrose. Designed for easy integration into high-volume OEM production lines. Ultrasonic spray technology provides excellent coating uniformity and repeatability, and the precise fine-tuning function produces tighter droplet distribution and smaller droplets for consistent and fast-drying dispersions.

2. Significant advantages
1. Excellent coating uniformity: Traditional spraying methods are prone to uneven coating thickness, which may cause abnormal blood coagulation or uneven distribution of additives in blood collection tubes when storing blood samples. Ultrasonic atomization spraying technology, with uniform tiny droplets generated by high-frequency vibration, ensures that the coating is evenly covered on the inner wall of the blood collection tube. Whether it is a straight tube section or a curved part, the coating thickness deviation is extremely small, ensuring the stability and consistency of the blood sample in the tube.
1. Saving raw materials: Ultrasonic atomization spraying can accurately control the coating thickness, avoiding material waste caused by excessive spraying. Traditional spraying methods often require repeated spraying to achieve a uniform effect, consuming a lot of raw materials. Ultrasonic technology only needs one precise spraying to meet the coating requirements, greatly reducing production costs. According to statistics, in large-scale production, the use of ultrasonic atomization spraying can save about 30% - 40% of raw materials.
1. Improve production efficiency: This technology has a fast spraying speed and a good one-time molding effect. On a continuous production line, blood collection tubes can quickly pass through the spraying area to complete high-quality coating operations. Compared with the traditional cumbersome processes of multiple spraying and drying, ultrasonic atomization spraying greatly shortens the production cycle. For example, after introducing this technology, the daily output of a large blood collection tube production company increased by more than 50%.
