Abstract
Transillumination uses light to image tissues and organs, specifically the veins within the tissue. Strong ambient light hinders the imaging of veins and often, transillumination must be done in a dark or dim room. To enhance the capabilities of a transilluminator, a light shield is placed over the viewing area of the transilluminator so that turning off or dimming of ambient light is not necessary. For pediatric care, a frustroconical adapter attached to the bottom of the transilluminator. The adapter reduces the size of the viewing area.
Claims5
A transillumination device to image veins within tissue, comprising
- a housing to be grasped by a user during use of said transillumination device, said housing having a top surface and a bottom surface;
- a light source in said housing provided on said bottom surface, surrounding a viewing area;
- the viewing area illuminated by said light source;
- a dome-shaped upper light shield having an upper surface and a viewing aperture extending above said top surface of the housing and over said viewing area, said upper light shield blocking ambient light above the viewing area but allowing the user to image veins within tissue;
- a lower light shield in direct contact with said upper light shield, said lower light shield provided around said light source and said viewing area;
- and
- an adapter depending from said bottom surface of said housing, said adapter being frusto conical and further wherein said adapter reduces the size of the viewing area.
