Description

Portable electrocardiosignal acquisition equipment Technical Field The invention relates to the technical field of electrocardiosignal acquisition, in particular to portable electrocardiosignal acquisition equipment. Background Electrocardiosignals are key physiological signals reflecting the electrical activity of the heart and play a vital role in diagnosing and monitoring heart diseases. The electrocardiosignal acquisition process comprises the following steps of firstly acquiring electrocardiosignals from the body surface of a human body through an electrocardiosignal detection electrode, amplifying the electrocardiosignals through an amplifying circuit, eliminating high-frequency interference through a filter circuit to extract the electrocardiosignals with the frequency in the range of 0.05-100 Hz, then converting the analog electrocardiosignals into digital signals through an A/D (analog to digital) conversion circuit and storing the digital signals in a data storage circuit, and finally displaying the digital signals on a screen of a graph display circuit. However, it is noted that conventional electrocardiographic monitoring devices often suffer from the disadvantages of being bulky, expensive, and not easily removable. These limitations largely prevent the use of electrocardiographic monitoring devices in real-time on-site patient condition monitoring. The utility model provides a chinese patent of CN202323379415.8 discloses a portable electrocardiograph, including the electrocardiograph body, the positive fixedly connected with fixing device of electrocardiograph body, the storehouse has been seted up at the top of electrocardiograph body, the mounting groove has been seted up to the inner chamber bottom of storehouse, the inner chamber swing joint of mounting groove has the mechanism of tearing open, electrically conductive liquid box has been placed to the inner chamber of storehouse, the inner chamber top swing joint of storehouse has the sliding closure, the back of electrocardiograph body is equipped with a plurality of wires, fixing device is including the shell, through being equipped with fixing device, can adjust and fix the position of bandage and tensile its length through fixing device, make the bandage after adapting to patient's health girth, through the upper body of bandage winding, make the electrocardiograph fix on patient's health and detect, further improve electrocardiograph's portability, make the patient can carry out simple removal when carrying out the electrocardiograph monitoring. Although the above device can adjust and stabilize the position of the binding band and the stretching length thereof by the fixing device, thereby significantly improving the portability of the electrocardiograph, some challenges are still faced in practical application. When the electrode contact of the electrocardiograph is in contact with a human body, if the electrode contact is in a low-temperature state, the vibration of muscles in a contact area is easy to occur, and the vibration can generate high-frequency baseline noise so as to interfere the accuracy of an electrocardiograph map displayed by the electrocardiograph. In addition, in order to ensure accurate capture of the electrocardiographic signals, the electrodes need to be closely attached to the skin surface of the human body. If the electrode connection is unstable, such as loosening or displacement, the contact area between the electrode and the skin is reduced, thereby preventing effective conduction of the electrocardiosignal. Meanwhile, the area where the electrode is connected with the human body needs to be kept in a wet state so as to reduce high impedance at the connection part, thereby avoiding the baseline drift phenomenon in the electrocardiograph monitoring process. In view of this, it is particularly critical and urgent to develop a portable electrocardiograph signal acquisition device capable of effectively overcoming the above technical problems.
