Tracing software captures the frame, data, provided by the high-accuracy of the frame reader. It stores the frame data along with the patient's prescription, including the lenses selection, coatings, tint, and other specifications into the computer and then transfers the order via a telephone line to a central lab. Once all of the information is entered, the operator can send a job one at a time or batch process to the host terminal, or central edging lab.

Traction Devices refers to the set of mechanisms for straightening broken bones or relieving pressure on the skeletal system. There are two types of traction: skin traction and skeletal traction. It is largely replaced now by more modern techniques, but certain approaches are still used today, Bryant's traction, Buck's traction - hip fractures, Dunlop's traction - humeral fractures in children, Russell's traction and Milwaukee brace - traction Milwaukee brace.

Traditional bone cements are primarily made of MMA and PMMA. It exhibits high exotherm of reaction, shrinkage, residual monomer, unsuitable mechanical properties, and cement loosening. It uses low toxicity activators, low heat of reaction monomers and bioactive ceramics to improve biocompatibility.

Training Stethoscope is designed for multi-function teaching applications. The dual head design offers the necessary flexibility to use this scope in all clinical and educational conditions. The training stethoscope comes complete with two binaurals, two pieces of Y-tubing, a Y connector, and an extension tube. Both the medical or nursing student and the instructor can hear the same sounds at the same time. The Bowles side of the chestpiece is fitted with an extra large diaphragm.
