Abstract

The invention relates to an implantable heart pacemaker packaging device. The packaging device comprises a packaging mould, a sealing plug cavity forming mould, a positioning rod for fixing the sealing plug cavity forming mould and an electrode positioning mandrel for forming a pace-making electrode cavity and for controlling and determining a position of an electrode square block, wherein a titanium shell holding cavity, a top cover forming cavity, a positioning rod connection hole, an electrode positioning mandrel connection hole, a feeding port and a vent port are arranged inside the packaging mould. Since the packaging device is ingeniously adopted, the top cover forming an implantable heart pacemaker is packaged to the top part of a titanium shell through a filling and sealing way, not only easiness in filling and sealing is achieved, but also positions of all parts forming the packaging device are relatively stable and accurately positioned; and meanwhile, a reasonable packaging method is adopted, so that the material forming the top cover is free from having the problems such as volume variation, bubbles and the like during the entire solidification process, the stability of the shape and the size of the top cover and cavities on the top cover can be guaranteed, and the strength, transparency performance and completion of the top cover also can be guaranteed.

Description

technical field [0001] The invention relates to the packaging field of implantable cardiac pacemakers, in particular to an implantable cardiac pacemaker packaging device and packaging method. Background technique [0002] An implantable cardiac pacemaker is a physiological electronic system that replaces or supplements the normal excitation and control of cardiac contraction. It stimulates the heart through periodic electrical pulses and causes heartbeats. It is often used for sinus arrest, sinoatrial block, and sinus arrest. Heart problems such as bradycardia or fast heartbeat. Existing implantable cardiac pacemakers usually consist of a titanium shell, a power circuit installed in the titanium shell, an electrode block electrically connected to the power circuit, a pacing electrode connected to the electrode block, and the top of the titanium shell. And it consists of a top cover formed by curing epoxy resin. Among them, the top cover has two functions: on the one hand, ...
