Description

Technical Field

[0001] This utility model relates to the field of insulin storage and semiconductor refrigeration technology, and in particular to a daily dual-use pack with integrated insulin storage function. Background Technology

[0002] Currently, diabetes is showing a trend of affecting younger people, with the number of patients constantly rising. Some diabetic patients need to inject insulin regularly, and insulin can only maintain its activity when stored within a temperature range of 2-8℃. At present, most insulin storage devices on the market are independent refrigerated boxes. This design has many drawbacks in practical use: patients need to carry them separately when going out, which takes up extra space and greatly reduces the convenience of travel; moreover, their appearance is obvious, making it easy for others to notice the user's condition, causing unnecessary psychological burden on the patient; in addition, from the perspective of power supply, existing devices are highly dependent on a single power source. Once there is a power outage, power supply failure, or power depletion, the insulin storage environment will be out of control, facing the risk of failure, seriously affecting the patient's normal treatment.

[0040] The working principle of this invention is as follows: A 12V DC battery 18 drives a semiconductor cooling chip 14 to achieve low-temperature storage of insulin at 2-8℃. The hot end of the semiconductor cooling chip 14 is cooled by a cooling fan 5 to prevent it from burning out. When the battery power is insufficient, the 12V DC battery 18 can be charged through a flexible solar photovoltaic film 3 to drive the semiconductor cooling chip 14. When there is insufficient sunlight and the battery power is insufficient, the 12V DC battery 18 can be charged through a hand-cranked generator. When the patient is at home or staying in a hotel, the 12V DC battery 18 can be charged through solar energy and the household power grid to ensure that the insulin is always kept within the temperature range of 2-8℃.
