Abstract

The invention discloses a patch, a coating device used for manufacturing the patch and a manufacturing method of the patch. The coating device comprises a patch material fixing device, a spray head and a spray head moving device. The spray head moving device comprises a first moving device body and a second moving device body connected with the first moving device body, the first moving device body is used for controlling the spray head to move in the first direction, and the second moving device body is used for controlling the spray head to move in the second direction. According to the coating device used for manufacturing the composite patch and the manufacturing method of the patch, in the spraying process, the moving trails of the spray head can be freely adjusted, and therefore an even coating effect is achieved; the thickness of a coating of the composite patch is adjustable, and the problem that the coating is excessively thick or thin in the production process is avoided; the surface of the manufactured composite patch is smooth and even, the hand feeling of the composite patch after coating is improved, and an implanting operation is facilitated for a doctor.

Description

technical field

[0001] The invention belongs to the field of biomedical material processing, and in particular relates to a patch, coating equipment for preparing the patch and a preparation method thereof. Background technique

[0002] Biological patch is the regeneration system of human beings in the new century, which can promote the repair function of the human body to complete the regeneration of new tissues. After the biological patch is implanted into the human body, it plays a very good supporting role and fills the missing tissue in the damaged part. Under the induction of the material, the human body's own repair function can gradually grow new tissue in the original position, replacing the biological patch. materials to complete the process of organ tissue regeneration.

[0003] At the present stage, artificially synthesized polymer material patches are commonly used clinically. However, these polymer material patches are mostly non-absorbable materials, which ar...
