4 results about "Implantable cardiac pacemaker" patented technology

The invention relates to the technical field of cardiac pacemakers, and particularly discloses an implantable cardiac pacemaker array type multi-excitation IPT wireless energy supply system and a mutual inductance analysis model and a transmission efficiency and output power analysis model thereof. According to the mutual inductance analysis model disclosed by the invention, an output power analysis model and a transmission efficiency analysis model of the IPT system are further constructed by analyzing the mutual inductance condition between the coils. According to the invention, the model enables the electric energy to be effectively transmitted in a relatively long distance and a complex human tissue environment, achieves the flexible control of the energy transmission, can adjust the working state of the transmitting coil according to the demands of the pacemaker, improves the transmission efficiency of the electric energy, and improves the reliability of the pacemaker. And the service life of the system is prolonged. Meanwhile, the technology also enhances the adjustable degree of the coupling coefficient, and optimizes the coupling effect by adjusting the coil parameters, thereby improving the energy transmission efficiency, and guaranteeing the stable operation of the cardiac pacemaker.

The utility model relates to the technical field of cardiac pacemakers, and discloses an impact resistance test device for an implantable cardiac pacemaker, which comprises a base, the top of which is fixedly provided with a mounting rack. The limiting seat and the display part are fixedly mounted on one side of the mounting frame, one end of the sliding column is fixedly mounted on the base, the other end of the sliding column is fixedly mounted on the mounting frame, and positioning plates used for positioning are fixedly mounted on the two sides of the mounting frame. According to the impact resistance test device for the implantable cardiac pacemaker, through the design of a positioning groove and a positioning sleeve, when a supporting plate is installed, the supporting plate can be clamped into the positioning groove through the positioning sleeve and matched with an upper installation frame, the supporting plate can be rapidly installed, meanwhile, a supporting effect can be achieved on a placement plate, and the practicability of the supporting plate can be improved; when testing is carried out, the sliding sleeve can be in contact with the spring, a buffering effect can be achieved, the sliding sleeve can be prevented from directly impacting the position over the limiting plate, and the situation that the service life of the limiting plate is short is avoided.
