Embodiment Construction

[0032] Such as figure 1 A device for diagnosing blood vessel blockage is shown, including a controller 1, a display module 2, a laser 3, a coupling device 4 for emitting laser light from the collection laser 3, a transmission optical fiber 5 connected to the coupling device 4, and detection of reflected laser light by the collection coupling device 4 6, the output end of the controller 1 is connected to the display module 2 and the laser 3 respectively, and the input end of the controller 1 is connected to the detector 6. The coupling device 4 adopts a coupler or a splitter.

[0033]The coupling device 4 is arranged beside the light-emitting end of the laser 3 , and the coupling device 4 is arranged beside the detector 6 . The laser 3 is used to emit laser light and enter the coupling device 4, and the laser light enters the transmission fiber through the coupling device 4; the laser can be a solid-state laser, a gas laser, a semiconductor laser, a fiber laser, a dye laser, e...

Abstract

The invention discloses a device and a method for diagnosing a blood vessel blockage part. The device comprises a controller, a display module, a laser device, a coupling device for collecting laser light emitted from the laser device, a transmission optical fiber connected with the coupling device, and a detector for collecting reflected laser light from the coupling device, wherein the output end of the controller is connected with the display module and the laser device respectively; and the input end of the controller is connected with the detector. The device has the following advantages: the positioning operation is accurate, a blood vessel blockage point can be quickly obtained, a plurality of blood vessel blockage points can be detected at the same time, a clear blood vessel blockage curve can be obtained and is simple and clear, the detection range is wide, the missed diagnosis rate is low, a contrast agent is not required, the non-blockage situation at the far end of the blockage part can be also confirmed at the same time, a reliable diagnosis basis is provided for surgical selection, and the detection of the blockage part cannot be influenced due to change of blood flow speed and blood flow waveform caused by limb extrusion. The device is simple in structure, convenient in operation, minimally-invasive and high in safety.

Description

technical field [0001] The invention relates to a diagnostic device for blood vessel blockage, in particular to a diagnostic device and a diagnostic method for diagnosing blood vessel blockage sites with laser light. Background technique [0002] According to the latest data released by the World Health Organization (WHO), cardiovascular disease is the leading cause of death worldwide. Worldwide, 1 out of every 3 deaths is due to cardiovascular disease. The mortality rate of cardiovascular disease is much higher than other diseases including cancer and AIDS, and it has become the "number one killer" of human health. [0003] The report shows that cardiovascular disease in China has continued to be the first cause of death among residents since 1990. In 2008, the death toll caused by cardiovascular disease accounted for 40.27% of the total death toll in the country, and the death toll among young adults aged 35 to 54 increased most rapidly. From 2010 to 2030, due to popula...
