Abstract
The vibration capsule has a movement generation unit, a movement control unit, a wireless communication unit and a power supply. The movement control unit provides instructions to the movement generation unit, which generates movements in configurable frequencies and duty cycles. The power supply unit provides power to the movement generation unit through movement control unit, which also decides work period and rest period for the capsule device. The vibration capsule device further includes a capsule movement detection unit, which includes at least one sensor unit and provides information to the wireless communication unit.
Claims10
A method to use a vibration capsule device, comprising
- starting a capsule movement unit configured to produce vibration at a vibration level comprising a first frequency and a first duty cycle;
- detecting a first acceleration through a first acceleration sensor;
- collecting at least three accelerations through the first acceleration sensor and forming a first group of data;
- identifying a second acceleration among the first group of data and recording the second acceleration as a first selected frequency;
- adjusting the duty cycle until a patient is comfortable with the vibration level;
- repeating the detecting and adjusting step for every 0.5-1 hour and stop the vibration when an accumulated vibration time is more than 3 hours.
A method to use a vibration capsule device, comprising introducing the vibration capsule device to a patient's gastrointestinal (GI) tract;
- moving a vibration capsule device at a resonant frequency of the patient's gastrointestinal motility, comprising
- a) starting a capsule movement unit at a first frequency f and a first duty cycle and detecting a first acceleration Af through a first acceleration sensor;
- b) vibrating the capsule movement unit at a second frequency f-m and at the first duty cycle, and detecting a second acceleration Af-m through the first acceleration sensor;
- and
- c) repeating steps b and a in a range from 1 Hertz (Hz) to 13 Hz and finding a maximum Af-n and identifying f-n as the resonant frequency of the GI tract of the patient;
- wherein 1 Hz<f-m<13 Hz, 1 Hz<f-n<13 Hz and 0.2<|m|<1.
