Abstract

The invention relates to a pacing generating device, comprising an impedance detection module that detects and outputs an impedance value of a pacing object, a pacing pulse sending module that applies a pacing pulse to the pacing object, receives an initial pacing current, The current is calculated to obtain the initial pacing voltage, the first processor that outputs the initial pacing voltage to the pacing pulse sending module, the second processor that outputs the adjustment signal according to the impedance value and the initial pacing current, and receives the adjustment signal and adjusts it according to the The signal adjusts the pacing voltage, and outputs the adjusted pacing voltage to the pacing boost module of the pacing pulse sending module; the impedance detection module is connected with the second processor, the pacing pulse sending module is connected with the first processor, and the second The first processor is connected to the second processor, the second processor is connected to the pacing boost module, and the pacing boost module is connected to the pacing pulse sending module, which can effectively ensure the safety of the current and voltage loaded on the pacing object.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a pacing generating device. Background technique [0002] The defibrillation monitor has the function of non-invasive pacing. In clinical emergency treatment occasions, it is often necessary to use the defibrillation monitor to treat patients with bradycardia with external non-invasive pacing. External non-invasive pacing is different from internal pacing. External pacing uses The internal circuit generates electrical pulses of a certain intensity and width, which are released to the heart through the electrodes to stimulate the myocardium and achieve therapeutic effects. The range of human chest resistance in vitro is wider than that in vivo, and the range of change is generally 20Ω~200Ω. Considering the contact impedance between the electrode pad and the human body, the impedance range that can be paced is generally 20Ω~750Ω; and the clinically effective stimulation pul...
