Description

Technical Field

[0001] The utility model relates to the technical field of medical monitoring, in particular to a wireless body temperature monitoring device. Background Art

[0002] Temperature monitoring is of great significance for the surgical process and postoperative recovery. For example, during surgery, by placing a temperature sensor under the armpit or in the ear canal, connecting a monitor, recording and monitoring the patient's temperature changes, it is used to monitor the patient's temperature during surgery and prevent intraoperative hypothermia. In addition, perioperative hypothermia leads to a series of postoperative complications such as delayed awakening, severe arrhythmia, and infection. Therefore, core temperature changes should be routinely monitored during surgery to prevent hypothermia and reduce the occurrence of postoperative complications. In addition, in order to prevent and treat perioperative hypothermia, core temperature should be routinely monitored before, during, and after surgery, so as to achieve the purpose of timely detection of hypothermia and prevention and treatment of hypothermia. However, temperature measurement is only the beginning. Effective intervention for intraoperative hypothermia is required in the future, including heating treatment. At the same time, if the heating treatment measures can be subdivided and adjusted in combination with the measurement results of the temperature sensor, better treatment effects will be achieved. Most of the existing wireless body temperature solutions collect surface temperature and cannot monitor body cavity temperature; body cavity temperature collection requires the use of a body cavity temperature probe, which is currently only available in wired form; existing wireless body temperature solutions require the addition of a dedicated terminal for display and cannot be adapted to the existing multi-parameter monitors in the operating room.
