Abstract

The invention provides a packaging device, a packaging method, a pulse generator and an implantable medical device. The packaging device comprises a first mold and a second mold which are matched with each other; the first mold is provided with a first groove matched with one side of a to-be-packaged piece, the second mold is provided with a second groove matched with the other side of the to-be-packaged piece, and a cavity used for containing the to-be-packaged piece is formed between the first groove and the second groove; one of the first groove and the second groove is provided with a glue injection port, and the other one of the first groove and the second groove is provided with an exhaust port. According to the invention, the front and back surfaces of the to-be-packaged piece can be injected with glue at the same time, and the glue injection efficiency is greatly improved. Besides, the problems of insufficient internal filling during glue injection, generation of bubbles after curing, lack of glue and the like can be avoided, meanwhile, the problems of lack of glue, bubbles and the like caused by expansion or contraction of glue liquid can be prevented, the waterproof sealing performance and the insulating performance of packaged products are guaranteed, and the product yield is increased.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a packaging device, a packaging method, a pulse generator and an implantable medical device. Background technique [0002] An implantable electrical nerve stimulation system is an active implantable medical device, which consists of three parts: a pulse generator, an extension lead, and an electrode lead. Depending on the actual application of the system, it may only include a pulse generator and an electrode lead. two parts. The implantable nerve electrical stimulation system excites, inhibits or mediates the conduction of the nervous system through electrical stimulation, so as to achieve the therapeutic effect of restoring or improving the function of the human body. Compared with traditional shell destruction surgery, implantable nerve electrical stimulation therapy is safe and reversible, and has obvious curative effect, and has been more and more clinically applied...
