Embodiment Construction

[0022] The 3D printing drug shell of the present invention can control the drug release rate to be constant, and its structure is a sphere with four cylindrical cavities with an included angle of 109.47°; the printing material is a polyvinyl alcohol wire; the application Occasionally, controlled-release drugs and occasions with high requirements for drug stability; the active ingredients of the drug are released at a constant speed; the manufacturing method is printing using an FDM type 3D printer.

[0023] First carry out the digital modeling of the enclosure. Use CAD computer-aided drawing software to build a regular tetrahedron with a side length of 10mm. Find the geometric center of the tetrahedron. Use this geometric center as the center of the sphere to make a sphere with a diameter of approximately 12.4mm. At this time, the tetrahedron is connected to the sphere. Connect the four corners of a regular tetrahedron to its geometric center to form four straight lines with th...

Abstract

The invention discloses a method for 3D printing of medicines and a 3D printing medicine shell. The medicine shell comprises four cylinder cavities, and included angles of the shaft lines of the cylinder cavities are all 109.47 degrees; the four shaft lines are equal in length, one ends of the four shaft lines are connected at one point, and the point is the geometric center of a regular tetrahedron; the four shaft lines are connecting lines of the center and the four peaks of the regular tetrahedron; and cylinders are arranged in a ball body, the ball center of the ball body and the geometric center are the same point, and the ball body is internally connected with the regular tetrahedron. The method is simple and reliable, and obtained pills are suitable for controlled release medicines and suitable for occasions with high requirements for medicine stability.

Description

Technical field [0001] The invention relates to the field of controlled release medicines, in particular to a method for 3D printing medicines and 3D printing medicine shells. Background technique [0002] Controlled release drugs have always been one of the focuses of pharmacokinetic research. To a certain extent, controlled release drugs can greatly improve the utilization efficiency of drugs. In modern pharmacy and clinical practice, controlled-release drugs have broad application prospects. Many scholars and manufacturers at home and abroad have made a lot of research results in this field. With the popularity of open source hardware, 3D printing technology has increasingly become a representative of advanced productivity. 3D printing is a cross-application of additive manufacturing methods that can generate complex structures and controlled-release drugs, and the release characteristics of drugs can be customized according to the specific requirements of patients. It has a...
