Cold compress bag and cold compress system comprising same

A cold compress bag, comprising:

• a first surface layer, an intermediate layer, and a second surface layer, wherein a liquid storage space is defined between the first surface layer and the intermediate layer, an air storage space is defined between the second surface layer and the intermediate layer, the air storage space is provided with a vent port, and the vent port is configured to communicate the air storage space with outside;
• a partition assembly, wherein the partition assembly is configured to connect to the first surface layer and the intermediate layer to divide the liquid storage space into a liquid inlet region, and a liquid outlet region in communication with the liquid inlet region, the liquid inlet region is provided with a liquid inlet port configured to communicate the liquid inlet region with the outside, and the liquid outlet region is provided with a liquid outlet port configured to communicate the liquid outlet region with the outside;
• and
• wherein the partition assembly comprises a primary partition and a secondary partition, the primary partition is configured to divide the liquid storage space along a second direction into the liquid inlet region and the liquid outlet region, the secondary partition is connected to the primary partition, an extending direction of the secondary partition forms an angle relative to an extending direction of the primary partition, the secondary partition extends in a curved manner in the second direction to define a transition passage on a side away from the liquid inlet port and the liquid outlet port, and the transition passage is configured to communicate the liquid inlet region with the liquid outlet region;
• and
• a plurality of guide portions, wherein the plurality of guide portions are configured to connect to the second surface layer and the intermediate layer to divide the air storage space along a first direction into a first clamping region, a retaining region, and a second clamping region in communication with one another, the plurality of guide portions are configured to connect to the first surface layer and the intermediate layer, the plurality of guide portions are spaced apart from an outer edge of the cold compress bag to define an outer passage between the plurality of guide portions and the outer edge of the cold compress bag, and the plurality of guide portions are spaced apart from the partition assembly to define an inner passage between the plurality of guide portions and the partition assembly;
• and the cold compress bag is bendable at the plurality of guide portions.
