Objective:To develop a safety protection device for lead cable of equipment in order to reduce or avoid the skin burn of patient and the invalidation of monitoring data caused by the short circuited of lead cable, and enhance the comfortable level of patient, at the same time, and reduce the pain of patient and potential adverse events.Methods: The device was consisted of the fixed sleeve of cylinder-shape (protective shell) and fixed sleeve of packaged cable (fixed sleeve of wire and cable), and its component was carbon fiber reinforced polycarbonate and silicone rubber. The fragile, repaired part or the rupture rubber of shell in upside and bottom of device were clamped in fixed sleeve. And then, the upside and bottom were fixed in one device, and take them socket with lead cable of device.Results: After the safety protection device of leading cable were used, the cable were fixed in the interior of the device, and could be protected. Therefore, some risks of adverse event were reduced and avoided.Conclusion: The device is stable in performance, is simple and convenient in operation and installation. In the application, it avoids the risk which caused by short circuit of cable in therapy monitoring, and could enhance the comfortable feel. This device is appropriate to various installation and application of lead cable, and it can be repeated to apply. It has got national patent for utility models due to its favourable application value.
