Description

Technical Field

[0001] The utility model relates to an insulin refrigeration box suitable for diabetic patients to carry when going out, and belongs to the technical field of diabetic patient nursing equipment. Background Art

[0002] Diabetes is a chronic disease characterized by hyperglycemia and caused by absolute or relative insulin deficiency and utilization disorder. The cause is mainly attributed to the combined effects of genetic and environmental factors, including pancreatic cell dysfunction leading to decreased insulin secretion, or the body's insensitivity to insulin, or both, which makes it impossible for glucose in the blood to be effectively utilized and stored.

[0003] At present, the incidence and prevalence of diabetes are on the rise, and the number of diabetic patients is increasing year by year. Diabetic patients need to inject insulin every day. When diabetic patients go out for long-distance self-driving tours, they need to carry insulin. Since the suitable temperature for insulin preservation is relatively low, usually 2-8 degrees Celsius, when carrying insulin out, it is necessary to provide a low-temperature refrigerated space for insulin. At present, when diabetic patients carry insulin out, they usually place ice bags inside the box to provide a refrigerated space for insulin. This method of refrigeration using ice bags has the following problems:

[0004] (1) As the ice pack melts, the temperature of the refrigerated space will also rise, which will affect the preservation of insulin;

[0005] (2) The ice pack needs to be taken out and placed in the refrigerator frequently for freezing, which is very inconvenient. The ice pack is highly dependent on the refrigerator during use;

[0006] (3) There is a risk of damage to the ice pack during repeated freezing. If the ice pack is damaged, it will affect its use;

[0007] (4) The time for which insulin can be refrigerated using ice packs is relatively short, which cannot meet the needs of diabetic patients for long-distance self-driving trips, and the scope of activities of diabetic patients outside is limited. Utility Model Content

The semiconductor refrigeration module is equivalent to being arranged between the refrigerated space 11 and the heat dissipation channel 12. The inlet and outlet of the heat dissipation channel 12 are respectively located at the two ends of the box body 1, and a fan 6 is arranged at the outlet of the heat dissipation channel 12; after the fan 6 starts working, air enters from the inlet of the heat dissipation channel 12 and is discharged from the outlet of the heat dissipation channel 12, thereby taking away the heat generated by the hot end of the semiconductor refrigeration module; a grille structure 7 is arranged at the inlet of the heat dissipation channel 12 to prevent foreign matter from entering the heat dissipation channel 12.

[0039] A shaft body 8 is arranged at the top opening of the refrigerated space 11, and a bearing plate 9 is rotatably arranged on the shaft body 8.
