Description

Technical Field

[0002] Vascular crisis is the most serious complication after finger replantation, directly affecting the survival of replanted fingers. Among them, the late crisis after surgery occurs after 48 hours, mainly vascular spasm. Among the related factors causing spasm, cold stimulation accounts for an absolute number. Therefore, in postoperative care, it is necessary to continuously and actively keep the replanted limb warm. The traditional method is to adjust the room temperature and continuously irradiate the replanted limb locally with an incandescent lamp for heat preservation, generally for 7 to 14 days. During the process of irradiating the replanted limb with an incandescent lamp for heat preservation, the height of the incandescent lamp needs to be maintained at 25 cm to 45 cm. However, due to the arc-shaped surface of the limb, part of the limb surface cannot be thermally insulated by the incandescent lamp, and during the irradiation process, nurses need to observe the affected limb frequently to avoid adverse events such as burns caused by too high temperature, increasing the workload of nurses. Currently, there is also a method of using an electric blanket to keep the replanted limb warm. Due to the special shape of the limb, it is easy to cause a large gap between the electric blanket and the replanted limb, affecting the heat preservation effect. Summary of the Invention
