Problems solved by technology

The spring clip at one end of the bridge wire is clamped to the cathode of the cardiac pacemaker lead, and the spring clip at the other end is clamped with the spring clip of the current damage test device, such as the spring clip at the end of the bridge wire and the spring clip of the ECG polyconductor or The spring clips of a certain lead of the 12-lead ECG are clamped to each other. Repeated use will easily lead to loosening and damage of the spring clips of the 12-lead ECG, which will affect the use. Large, affecting the tracing and measurement of injury current

Abstract

The invention discloses a bidirectional adapter for connecting a cardiac pacemaker and test equipment. The bidirectional adapter comprises a conductive metal body located in the middle and two electrode plates located at the two ends of the conductive metal body. The two electrode plates are provided with electrode contacts which are respectively used for being connected with a spring clip of a bridge line of the cardiac pacemaker and a spring clip of the test equipment. Compared with the traditional direct clamping contact through spring clips, the bidirectional adapter avoids the problems that the spring clips are easy to damage, the connection is not firm, the contact is poor and the like when the two spring clips are directly clamped and connected with each other in the prior art, increases the connection firmness of a damage current testing device, avoids the electric signal interference caused by the poor contact and improves the conductivity and the testing accuracy, and meanwhile, the bidirectional adapter of the structure is beneficial for increasing the contact area, reducing the measurement error and ensuring that stable and reliable damage current measurement parameters are provided, improves the durability of the damage current testing device, reduces the damage rate and lowers the cost.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a bidirectional adapter for connecting cardiac pacemaker leads and testing equipment. Background technique [0002] One of the important steps in implanting a permanent cardiac pacemaker is to test whether the parameters of the electrode leads positioned at specific parts of the endocardium can meet the requirements for long-term pacing of the heart. When testing the pacing electrode lead, due to the need of aseptic operation, it is not possible to directly connect the end plug of the electrode lead to the connection line of the test equipment on the operating table, but to use a sterile transfer line Or the connector connects the terminal connector of the electrode lead with the signal input line of the test equipment, the main purpose of which is to prevent contamination of the terminal plug of the electrode lead and the operation area. At present, most of ...
