The application provides a tumor electric field treatment system and an alternating electric signal application method, which are used for applying an alternating electric field to a tumor part of a human body. The system comprises an electric field treatment device and at least two pairs of electrodes electrically connected to the electric field treatment device. The electric field treatment device cyclically and alternately outputs AC voltages to each pair of electrodes. One cycle is defined as one time of outputting an AC voltage to each pair of electrodes by the electric field treatment device. The peak-to-peak voltage in each cycle is a specific voltage. The electric field treatment device is provided with an initial voltage V c and a maximum specific voltage for the AC voltage output to each pair of electrodes. When the electric field treatment device starts to work, the AC voltage output to each pair of electrodes is increased from the initial voltage to the maximum specific voltage by a voltage increasing step △V in a preset total voltage increasing time T0. The tumor electric field treatment system of the application can avoid the generation of electric stimulation and prevent the patient from feeling uncomfortable during treatment.

This invention discloses a home-based sleep quality optimization aid for patients with chronic diseases, relating to the field of sleep assistance technology. It includes an adjustment controller and a wire. One end of the wire is fitted with an earplug, and the other end of the earplug is fitted with a rubber sleeve. An elastic strip is provided on the outer circumference of the earplug for conforming to the patient's concha. A detection component for detecting the patient's sleep state and a stimulation component for optimizing the patient's sleep quality are located on one side of the elastic strip. The stimulation component includes an outer sleeve fixedly connected to the elastic strip, an inner sleeve fixedly connected inside the outer sleeve, and a first electrode disposed inside the outer sleeve. This invention can effectively improve sleep problems such as difficulty falling asleep, frequent awakenings at night, and insufficient deep sleep duration in this population, breaking the vicious cycle of poor sleep quality and slow recovery, effectively optimizing the home-based sleep quality of patients with chronic diseases, and aiding in physical recovery.
