Positive electrode and negative electrode connection integrated structure of implantable pacemaker

Abstract

The invention discloses an integrated positive and negative electrode connection structure of an implantable cardiac pacemaker, which includes an elastic member, a jacket and a sealing ring. The two ports are sealed with ring seals. The device can not only provide reliable contact (clamping force) with the electrode plug and as small insertion and extraction force as possible, but also can provide pacemaker for the implantable heart pacemaker when the epoxy top of the implantable cardiac pacemaker is made. The positive and negative connectors of the device provide a reliable sealing environment to ensure that the performance of the main functional part of the connector is intact, and the structure is simple and easy to process, which further reduces the processing cost.

Description

technical field [0001] The invention belongs to the technical field of medical equipment and is applied to the signal transmission of an implantable cardiac pacemaker, in particular to an integrated structure for connecting positive and negative poles of the implantable cardiac pacemaker. Background technique [0002] The realization of all functions of an implantable cardiac pacemaker depends on the sending and receiving of pacing signals or sensory signals. (Standard size) Contact with the positive and negative connectors of implantable cardiac pacemakers is the only way for current implantable cardiac pacemaker signal transmission. For the positive and negative connectors of implantable cardiac pacemakers, it is required to be in reliable contact with the electrode plug and to be easy to plug in and out. At present, the positive and negative connectors of implantable cardiac pacemakers mainly have the following problems: [0003] 1. The contact with the electrode plug c...

AI Technical Summary

Problems solved by technology

[0003] 1. The contact with the electrode plug can be firm, but the plugging and pulling force of the electrode plug is very large, which is inconvenient for the doctor to operate, and it is easy to cause the electrode plug to be placed incorrectly.

[0004] 2. The insertion and extraction force provided during use is not strong, but it cannot guarantee a firm contact with the electrode plug, which may easily cause poor signal

[0005] 3. During the production process of the epoxy top of the implantable cardiac pacemaker, the sealing of the positive and negative connecting bodies of the implantable cardiac pacemaker is not good, which may easily cause deformation of the elastic parts in the connecting body, resulting in implantable cardiac pacemaker The positive and negative connectors of the pacemaker are in poor contact with the electrode plug or even cannot be conducted, and the implantable pacemaker cannot work normally.
