Patch type ECG collecting device

The invention discloses a patch type ECG collecting device which comprises a shell made of a flat flexible material and suitable for being attached to human skin. A first electrode and a second electrode are arranged on the front face of the shell and used for being attached to the human skin through adhesive tape and collecting ECG signals. The shell, the first electrode and the second electrodeare formed into a whole in a liquid silica gel injection forming mode or solid silica gel compression molding mode. A circuit module for processing the collected ECG data is arranged in the shell in asealed mode. The circuit module is connected with the first electrode and the second electrode. The patch type ECG collecting device is convenient to use, the electrodes can be recycled and cost is saved, the patch type ECG collecting device can not cause discomfort to the human skin after being worn for a long time, the sealing and waterproofing performance is good, the continuous use time is long, and data collection is
