MEDICAL OPTICAL COMPOSITE CABLE MANUFACTURING INTERMEDIATE, MEDICAL OPTICAL COMPOSITE CABLE MANUFACTURING METHOD AND CATHETER

摘要

PROBLEM TO BE SOLVED: To provide an intermediate for manufacturing a medical optical composite cable for manufacturing a medical optical composite cable that can avoid an occurrence of a microbending loss in an optical fiber, and can be accommodated in a catheter tube of an existing size, a method of manufacturing the medical optical composite cable, and a method of manufacturing a catheter.SOLUTION: An intermediate 100 for manufacturing a medical optical composite cable includes an assembled wire 103 formed by assembling an optical fiber 101 and a soluble yarn 102, and an electric wire 104 spirally wound around the assembled wire 103. A method of manufacturing the medical optical composite cable includes a step of forming the assembled wire 103 by assembling the optical fiber 101 and the soluble yarn 102, a step of spirally winding the electric wire 104 around the assembled wire 103, and a step of dissolving and removing the soluble yarn 102. A method of manufacturing a catheter is for manufacturing a catheter 300 by accommodating the intermediate 100 for manufacturing a medical optical composite cable in a catheter tube 301 after the soluble yarn 102 is dissolved and removed.SELECTED DRAWING: Figure 1
