Abstract
Description
Technical Field
[0001] The present application relates to the technical field of laser therapy, and in particular to a medical switching optical fiber. Background Art
[0002] Optical fiber is a light transmission tool that uses the principle of total internal reflection of light in the fiber. Currently, optical fiber is widely used in the field of physical therapy, especially in laser therapy, pet laser therapy, and beauty laser therapy. However, the inner diameter of the tube of a general physical therapy device is relatively small, and it is usually necessary to fuse a large-diameter optical fiber with a small-diameter optical fiber before use.
[0003] At present, in order to protect the joints of optical fibers, a protective cover is generally set at the joints of two optical fibers. Although the protective cover currently set at the optical fiber joints can protect the joints of the two optical fibers, the protective cover can only isolate the fusion splice from the external environment. However, the optical fiber will be subjected to a certain degree of tension during use. When it is suddenly subjected to a large tension, the tension will also be transmitted to the joint of the two optical fibers, causing the fusion splice to break. Therefore, there is an urgent need for a medical adapter optical fiber to solve this problem. Utility Model Content
