A biodegradable drinking straw and a manufacturing method thereof, the biodegradable drinking straw includes: a plant fiber material, which accounts for 5 wt % to 60 wt % of the total weight of the biodegradable drinking straw; and a biodegradable plastic selected from polylactic acid (PLA), polybutylene succinate (PBS) or a combination thereof; the biodegradable plastic accounts for 40 wt % to 95 wt % of the total weight of the biodegradable drinking straw; the fiber material is mixed into the biodegradable plastic and mixed uniformly and then extruded to form a tube body of the biodegradable drinking straw by extrusion molding. By replacing the traditional straw material with plant fibers and biodegradable plastics, the biodegradable drinking straw can be quickly decomposed naturally in the environment after being buried, thus reducing environmental pollution, and meeting the environmental protection requirements.

A method of manufacturing a medical component includes molding a first member of the medical component from an elastomeric material. The first member includes a first end defined by a closed base wall, an opposing second end which is an open end, a sidewall extending between the first and second ends, and an internal recess to receive at least one electronic device. The method further includes positioning the electronic device within the recess of the first member to form an assembly, such that the electronic device is received in an inverted open cavity defined by the sidewall. The method further includes applying a protective film on the second end of the first member, such that the protective film covers an exposed surface of the electronic device. In addition, the method includes overmolding the assembly with the elastomeric material to form the medical component having the electronic device embedded therein.
