C-type intermittent decompression air inflating air ring

The utility model discloses a C-type intermittent decompression air inflating air ring which comprises a C-type air ring body, at least three air inflating air bins are arranged on the air ring body, any two adjacent air inflating air bins are not communicated mutually, and two air inflating air bins which are separated by one air inflating air bin are communicated mutually. The C-type intermittent decompression air inflating air ring is used for decompression for bone protuberance positions of a patient in bed for a long time to prevent pressure sores from forming, or for carrying out partial decompression on a patient with the pressure sores formed, facilitates dressing replacing and promotes healing. Moreover, the C-type intermittent decompression air inflating air ring is labor-saving, after placed, the air ring needs not to be replaced constantly, due to the C-type style, humidity and hot air are prone to emitting, partial air is circulated, oxygen supply is better, comfort of the patient is stronger, an
