Description

Technical Field

[0001] The invention relates to the technical field of electrocardiogram monitors, and in particular to a data acquisition device for an improved electrocardiogram monitor. Background Art

[0002] All patients in the ICU need to use an ECG monitor. During the transfer or examination process, monitoring is still the first priority to ensure safety. The ECG monitors in the prior art have the following defects in actual use: First, the monitor lead wires are cumbersome and easy to get tangled; second, the conversion connector between the lead wire and the monitor is often pressed under the patient when turning over during use; third, the transport monitor needs to be replaced during the transfer process, which poses a risk; fourth, the lead wires are cumbersome, and the position of the electrodes needs to be changed when rescuing the patient to prevent affecting the rescue; fifth, for patients with autonomous activities, the existing lead wires greatly affect the patient's activities.

[0003] In the prior art, there is a Chinese invention patent with patent number CN2016101780724, and the patent name is Wearable 12-lead Remote ECG Monitoring Device and Its Application System and Method, which provides a wearable 12-lead remote ECG monitoring device, including a wearable body, an electrode interface, 12 heart electrodes, lead wires and an ECG analysis unit, wherein one heart electrode is arranged on the back of the wearable body, and the other 11 heart electrodes are connected together through the lead wires and connected to the electrode interface, and the electrode interface is connected to the ECG analysis unit. It solves the problem that the ECG detection system cannot realize remote real-time dynamic monitoring of the patient's ECG information and cannot screen out abnormal ECGs. However, this technology is 12-lead, which is not suitable for long-term clinical use. Secondly, this technology is simple ECG monitoring, and there is no monitoring of the patient's blood oxygen saturation and blood pressure.

[0004] At the same time, in the prior art, such as the Chinese utility model patent with patent number CN2018213362786, the patent name is a kind of electrode patch device bandage with integrated communication network, which provides an electrode patch device bandage with integrated communication network, which includes a band body, electrodes for collecting electrocardiographic signals, and a signal processing device for encoding and wirelessly transmitting electrocardiographic signals. The electrodes are arranged on the band body, and the signal processing device is also arranged on the band body. The electrodes and the signal processing device communicate through the communication network device. It integrates the electrode patch device and the band body into one, which saves the step of installing the electrode patch device separately and is more convenient to use. The band body can move with the patient, so that the patient is not bound by the cable of the electrocardiogram monitor and can move freely in the ward. However, this technology band body will oppress the patient, and how to process the signals collected by the electrodes and where to set the module for wirelessly transmitting the processed signals to achieve convenient installation and firm fixation are all unresolved.

[0005] In view of this, it is particularly important to design and manufacture a data acquisition device that allows medical staff to remotely understand the patient's vital signs, can move with the patient at any time, and has little impact on the patient's activities, and is used in electrocardiogram monitors.
