Embodiment Construction

[0013] The principle of the present invention is as figure 1 As shown, the core part of the whole device includes two parts: one is the image acquisition part. It includes an array of light-emitting diodes for illumination and its driving circuit, an optical path for optical imaging, and an image sensor for image data acquisition. The second is the ASIC circuit for image radio transmission, including a microcontroller for system control, a transceiver device for receiving and transmitting radio frequency signals, an antenna, and a transceiver switch. The microcontroller is mainly used to control the working state of the image sensor, the image acquisition rate, the data modulation method, the data encoding method, the working state of the radio frequency transceiver, etc.

[0014] The front end of the medical radio capsule has a spherical transparent glass cover, such as figure 2 shown. Its casing is made of acid-resistant, alkali-resistant and non-toxic materials. A lens...

Abstract

The present invention relates to electronic engineering and biomedical engineering technology. The medical radio capsule of the present invention is used for radio endoscope system, and the present invention makes the endoscope system not limited by connecting cable. Two main problems are solved, the first one is to convert wired communication into radio communication via separating the image collection and transmission part of endoscope system inside the radio capsule from its other part and transmitting collected image data to outside body for processing in the image station, and the second one is to lower the power consumption of battery powered system via adopting mini power consumption device and ASIC. In addition, the system can control remotely the operation state and parametersof image collecting unit inside body via the radio remote controller outside body.

Description

technical field [0001] The invention belongs to the fields of electronics and biomedical engineering, and is a novel diagnostic device for digestive tract diseases. Background technique [0002] The use of endoscopy is the most important means of diagnosis of digestive system diseases. At present, there is no in vitro imaging system (such as MRI, CT, gastrointestinal contrast, etc.) that can compare with it. However, in traditional endoscope systems, the power supply of the image collector and the communication between the image collector and the system are realized through cables. The use of the cables not only limits the inspection range of the endoscope, but also brings pain to the patient. For example, when push endoscopy is used for digestive system inspection, the examinee suffers a lot, so it is not suitable for elderly, weak and critically ill patients; at the same time, the patient will also face the risk of infection Risk of infectious disease. In order to cont...
