Description

Technical Field

[0001] The utility model relates to the technical field of cold compress devices, in particular to an upper limb sling with a cold compress function. Background Art

[0002] After an upper limb fracture, the upper limb needs to be suspended and fixed in front of the chest with a sling to avoid upper limb movement. Patients with upper limb fractures usually have edema, and cold compress is needed to eliminate edema. The traditional cold compress is to soak a small towel in cold or ice water, wring it half dry, apply it to the local area, change it every 1-3 minutes, and continue for 15-20 minutes, or wrap an ice pack in a towel and apply it to the local area.

[0003] The traditional ice compress method is extremely inconvenient for patients with fractures who need to use upper limb slings for fixation. Towels or ice packs need to be frequently replaced, and the patient's affected limb needs to be moved frequently, which is not only not conducive to the recovery of the patient's affected limb, but also limits the patient's range of motion due to the need to change towels or ice packs during cold compress.

[0034] The upper end of the thermal insulation sheet 25 is provided with two positioning rods 3 which correspond to the semiconductor cooling sheet 29 one by one and are both inclined upward and forwardly arranged. The front end of the outer wall of each positioning rod 3 is installed with a cooling fan 31 which cooperates with it. A micro water pump 32 and a battery 33 are installed on the other side of the upper end of the thermal insulation sheet 25.

At the same time, the temperature sensor 37 monitors the temperature of the cooling liquid in real time to prevent the temperature of the cooling liquid from being too low or too high, which affects the cold compress effect. When the semiconductor refrigeration chip 29 is working, the heat dissipation fan 31 on the positioning rod 3 also works at the same time to dissipate the heat from the hot end of the semiconductor refrigeration chip 29, thereby improving the cooling efficiency of the semiconductor refrigeration chip 29.
