Embodiment 1

[0071] #In the light source module, a light source group and a uniform light mirror group are installed. After the light source passes through the homogenizing mirror group, it evenly illuminates the surface of the human body. In the light source group, there are two light sources with wavelengths of 750nm and 850nm respectively. When in use, these two wavelengths are turned on in turn, and the cycle repeats.

[0072] #In the camera module, a background light filter, an imaging lens and a camera chip are installed. The background light filter is used to filter out the visible light source existing in the background, the wavelength is 300nm-700nm, and the light source of 700nm-900nm can pass through. The imaging lens makes the camera chip form an optical conjugate relationship with the surface of the human body, thereby realizing imaging. The camera chip collects images continuously, and uses the intensity changes generated by the sequential turning on of the two light sourc...

Abstract

The invention discloses intelligent visual vascular imaging spectacles equipment which comprises a pair of spectacles, a camera shooting module, a multi-light-source module, a micro-display module and a digital processing module. The pair of spectacles comprises a spectacles frame and lenses. The spectacles frame is internally provided with the camera shooting module and the multi-light-source module. The multi-light-source module is used for lighting the body surface. The camera shooting module is used for shooting images lightened by the multi-light-source module. The shot images are transmitted to the micro-display module after being enhanced by the digital processing module to be observed by medical staff. The micro-display module is provided with a miniature LCD display module. The camera shooting module and the micro-display module are driven by the digital processing module. The intelligent visual vascular imaging spectacles equipment, serving as a wearable device, has the advantage of being convenient to carry. Meanwhile, the micro-display module based on total internal reflection is designed, the optical path is increased through total internal reflection, and the field of view of the micro-display module is increased.

Description

technical field [0001] The invention relates to the field of smart glasses equipment and enhanced image display of venous blood vessels, and provides a smart glasses equipment for visualization of blood vessels. The invention combines infrared optical technology to assist medical workers to observe the position of blood vessels on the body surface. Background technique [0002] Intravenous injection is a common job for medical workers. However, because the position of blood vessels in some people is not easy to be observed, there may be cases of wrong ligation. This phenomenon is more prominent for newcomers who are new to medical care work, and it will also bring serious doctor-patient disputes. [0003] In the prior art scheme, there are two types of methods that can assist medical personnel to complete intravenous injection. One is a red light stick. The patients to be injected can improve the identification of blood vessels by holding the red light stick in their han...
