Description

Capsule type endoscope system and waistband Technical Field The invention relates to the technical field of electricity, in particular to a capsule type endoscope system and a waistband. Background The capsule type endoscope system comprises a capsule and a recorder, wherein an image pickup device is arranged in the capsule, after a user swallows the capsule, the capsule moves in a body cavity of the user along with the peristalsis of the alimentary canal of the user and the action of gravity on the capsule, and in the moving process, the image pickup device in the capsule picks up images in real time, and the obtained images are transmitted to the recorder in a wireless mode for display or storage. The recorder is worn on the body of a user, and is provided with an antenna which is used for realizing wireless communication between the capsule and the recorder. In the prior art, the antenna is arranged on the waistband, the waistband is bound on the waist of a user, and the wireless signals can be normally received between the capsule and the recorder only when the waistband is required to be clung to the body during the operation of the capsule type endoscope system because the antenna has limited transmitting power, the wireless signals have limited power requirements in the medical instrument standard, and the body tissues have attenuation effects on the wireless signals.
