The invention provides a near-infrared oxygenation treatment cabin. According to figure 1, a lower compartment is composed of a bottom plate of which the length is 2 meters, the width is 1 meter and the height is 0.3 meter; upper covers 2 and 3 are composed of two sections of which the length is 1 meter, the width is 1 meter and the height is 0.3 meter; the top end of a treatment cabin body is provided with a circular air hole 10, and the two sides walls of the lower compartment are provided with two circular air holes 10; the portion which is 10 centimeters above the inner bottom of the lowercompartment is provided with a bed drawer; the upper cover 2 of the treatment cabin body is provided with an observation window 4, an oximeter 5, a heart rate monitor 6, a sphygmomanometer 7, a thermometer 8 and a timer 9. According to figure 2, each treating plate is composed of fixed high-power LED near-infrared emitting diodes 2 and an insulating plate 1, wherein the fixed high-power LED near-infrared emitting diodes 2 are in series and parallel combination to be fixed on the insulating plate 1; all the treating plates are connected in parallel to be fixed on six faces of cabin plates in the cabin; and two lead wires of the general parallel connection of the treating plates are connected with a power supply device. According to figure 3, the power supply device is charged by a power source AC220V/110V, and composed of a power switch K, an indicator light L, silicon controlled voltage regulator A and a power transformer B. The near-infrared oxygenation treatment cabin has excellentcurative effects on severe anoxic patients, cardiovascular and cerebrovascular diseases, diabetic complications, and pain and other diseases.
