Board-card electrophysiological signal amplification system

Abstract

The invention relates to the technical field of medical instruments, and in particular to a board-card electrophysiological signal amplification system. The board-card electrophysiological signal amplification system comprises an accessory unit, an electrophysiological signal amplification device, an operation workstation and a graphic workstation; the accessory unit is a medical peripheral deviceand medical consumables; a signal input port of the accessory unit is connected with a patient by using the medical consumables; a signal output port of the accessory unit is connected with a signalinput end of the physiological signal amplification device by using a medical conduit / connecting cable; and a signal output end of the physiological signal amplification device is connected with the operation workstation and the graphic workstation by using a wired / wireless connection mode. According to the invention, different functional modules are arranged on a plurality of different board cards and then are connected with a case unit, so that the problem that a whole mainboard card needs to be tested and diagnosed once an existing single-board card electrophysiological system has a problemis solved, the overall size of an electrophysiological system is reduced, and thus the electrophysiological system is convenient to debug, install, maintain and upgrade.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a board-type electrophysiological signal amplification system. Background technique [0002] In the medical field, especially in interventional surgery, electrophysiological systems and intracardiac mapping catheters are usually used to perform cardiac ablation therapy to treat diseases caused by ectopic cardiac pacing such as atrial fibrillation and atrial flutter. For current electrophysiological systems such as figure 1 As shown, its structure is mainly composed of three major parts, namely patient connection unit, amplifier and doctor graphics workstation. Patients undergoing interventional surgery are connected to the electrophysiological signal amplification device through medical catheters and a series of connecting cables. After the patient's electrophysiological signal is amplified by the electrophysiological signal amplification device, it is sent to the operat...

Problems solved by technology

[0003] However, the existing electrophysiological system usually adopts a single-board design, that is, all the above-mentioned functions are integrated on a single motherboard, just like the motherboard of a computer, through the slots and connectors on the board to connect external equipment and device

Although this kind of design seems straightforward, the utilization efficiency inside the chassis is not high, resulting in the product being too large and inconvenient for transportation and installation; Complete replacement takes a lot of time and labor for assembly, debugging, and maintenance personnel, which does not meet the requirements of hospitals using these equipment for equipment maintenance, especially for the time and efficiency of on-site maintenance; at the same time, due to the large size of the main board, it is not suitable for automation. The test system can only use manual testing, which has the problems of complicated procedures and time-consuming. At the same time, due to factors such as the testers' own quality and training, it is relatively easy to make mistakes, thereby reducing the overall reliability of the product.

[0004] On the other hand, existing electrophysiological systems often expand the number of acquisition channels and other functions such as calibration and positioning due to user needs.

In this regard, it is often necessary to redesign, retest, and re-register the product as a whole, which consumes a lot of economic and time costs. The hardware upgrade of the single-board electrophysiological system is particularly difficult, and it cannot meet the latest market demand in time.
