Description

Technical Field

[0001] The utility model belongs to the technical field of spraying equipment, and in particular relates to spraying equipment for coating a medical phosphorylcholine coating. Background Art

[0002] Medical phosphorylcholine coating is a layer of phosphorylcholine film sprayed on the surface of medical stents or balloon catheters using ultrasonic spraying technology to increase the anti-coagulation effect of medical stents or balloon catheters. Ultrasonic spray equipment is used as a nozzle during spraying. The ultrasonic spray equipment uses high-frequency vibration to disperse the phosphorylcholine liquid into tiny droplets and dry them on the surface of the coated object.

[0003] When the existing medical phosphorylcholine coating spraying equipment is in use, the medical stent lamp is placed on the placement board, and then the coating is sprayed on its surface through an ultrasonic nozzle. During the spraying process, the door panel will be closed, and personnel will observe the spraying effect of the internal medical stent through the transparent observation window on the door panel. However, during the spraying process, some liquid is easy to drift to the surface of the transparent observation window facing the inside of the equipment, causing the back of the transparent observation window to be covered with liquid, making it difficult for personnel to see the nozzle status of the medical stent inside the equipment from the outside, reducing the spraying effect of the spraying equipment. For this reason, we propose a medical phosphorylcholine coating spraying equipment. Utility Model Content
