Embodiment Construction
[0020] The present invention will be described in detail below in conjunction with the accompanying drawings. However, it should be understood that the accompanying drawings are provided only for better understanding of the present invention, and they should not be construed as limiting the present invention.
[0021] Such as figure 1 As shown, the present invention provides a tumor blood flow rate monitoring device based on a descending thoracic aortic stent, which includes a stent graft, an integrated circuit and an external processing device.
[0022] The covered stent is used as an antenna for energy and signal transmission, and is composed of an intima, a stent body and an adventitia, the intima is arranged inside the stent body, and the adventitia is arranged outside the stent body.
[0023] The integrated circuit is arranged outside the stent-graft, and the integrated circuit can be fixed on the adventitia, or the integrated circuit can be placed between the stent-graf...

The invention relates to a blood flow speed monitoring device and method based on a thoracic descending aorta stent. The device comprises the coated stent, an integrated circuit and external treatment equipment. The integrated circuit is arranged outside the coated stent and comprises an energy supply module, a blood flow speed sensor, a storage device, a data processor and a first radiofrequency receiving and transmitting module. The energy supply module is used for supplying electricity to the integrated circuit, the blood flow speed sensor is used for transmitting detected blood flow speed signals to the data processor through the storage device, the data processor is used for converting the blood flow speed signals into digital signals and loading the ID of the integrated circuit and time stamp information, the first radiofrequency receiving and transmitting module is used for transmitting the digital signals to the external processing equipment through the coated stent, and the functions of data measurement and signal transmission are achieved. The blood flow speed monitoring device is small in size and radiation, capable of monitoring a patient in real time and capable of being widely applied to monitoring the state of thoracic descending aorta tumors.
Description
technical field [0001] The invention relates to a blood flow velocity monitoring device and a method thereof, in particular to a blood flow velocity monitoring device and a method thereof based on a descending thoracic aortic stent applied in the technical field of medical detection. Background technique [0002] Aortic aneurysm is a clinically common vascular disease that mostly occurs in the elderly. This disease can lead to aortic aneurysm rupture, which poses a great threat to the life of patients. With the continuous development of modern medical technology, the use of minimally invasive surgery to implant covered stents into the human body to treat aortic aneurysms and dissecting aneurysms is being used more and more. This treatment device compresses the artificial covered stent into the delivery and release device, sends it into the human body along the guide wire implanted in advance, and delivers the delivery and release device to the diseased aorta, and then releas...
