Reducing temperature of high power led in medical sensors

A patient monitoring sensor having a communication interface is provided through which the patient monitoring sensor is capable of communicating with a monitor. A patient monitoring sensor includes a light emitting diode (LED) communicatively coupled to the communication interface and a detector communicatively coupled to the communication interface capable of detecting light. The patient monitoring sensor includes a layer of material disposed on the patient side of the sensor over the LED to reduce heat transfer from the LED to the patient's skin. 提供了一种具有通信接口的患者监测传感器，该患者监测传感器能够通过该通信接口与监测器通信。患者监测传感器包括通信地耦合至该通信接口的发光二极管(LED)以及通信地耦合至该通信接口的、能够检测光的检测器。患者监测传感器包括材料层，该材料层设置在传感器的患者侧上、LED上方，以减少从该LED传递到患者皮肤的热。
