The invention discloses a wearable labor analgesia device. The wearable labor analgesia device is characterized by comprising a housing, a belt body and an electrode plate which are sequentially connected; an analgesia block for generating analgesia electronic stimulus waveforms is arranged in the housing; a conductor is arranged in the belt body and used for transmitting the generated electronic stimulus waveforms generated by the analgesia block to the electrode plate; a pressure sensor, an uterine pressure processing circuit and a feedback unit are arranged in the housing. According to the wearable labor analgesia device, cables are not used to coil a pregnant woman, so that the pregnant woman can move freely during analgesia; in addition, the uterine pressure can be monitored during analgesia, and the analgesia waveforms can be guided and outputted according to the uterine pressure signal. The device is convenient to use, relatively low in cost, and beneficial for popularization and application.
