For diabetic patients, insulin is an indispensable drug in daily treatment. It can help stabilize blood sugar and prevent complications. However, insulin is very "delicate" and must be stored in the refrigerator within a temperature range of 2 to 8 degrees Celsius to ensure its efficacy. Both excessively high and low temperatures can cause insulin to lose its effectiveness. So the question arises: When patients need to go out for something, what methods can be used to keep insulin within a safe temperature range?

TEC refrigeration box VS ice pack

Ice packs/refrigerated bags: Ice cubes absorb heat and cool

The simplest way is to cool the insulin with an ice pack or cold storage bag. Although it is simple to operate and has a low cost, this method lacks active temperature control capability and is difficult to meet the long-term stable storage requirements.

1. Slow cooling speed: It cannot cool down quickly when first placed in and takes a long time to reach the target temperature.

2. Unstable temperature: The refrigeration effect of ice packs is not long-lasting, and the temperature can change at any time after the ice cubes melt.

3. Prone to freezing: If there are too many ice cubes or they are too close together, insulin may freeze, causing the medicine to deteriorate.

TEC Portable Refrigeration Box: Thermoelectric cooling technology

To achieve stable and precise constant-temperature storage of insulin, portable refrigeration boxes based on thermoelectric cooling technology are becoming a better choice. It relies on the Peltier effect to achieve active cooling and precise temperature control, equivalent to a portable mini refrigerator, stabilizing the temperature of the medicine within an effective range. Its advantages include:

1. Precise temperature control: The temperature control accuracy is within ±0.5℃, ensuring that the drug will not lose its efficacy due to repeated temperature fluctuations.

2. Rapid cooling: No matter how high the ambient temperature is, it can quickly cool insulin to the target range after being powered on.

3. Anti-freezing: Built-in temperature protection mechanism (not lower than 0℃) to prevent insulin from freezing.

4. Low-noise operation: It makes almost no noise during operation and does not cause interference when carried around.

5. Long battery life: Supports USB charging and can be connected to a power bank to meet the refrigeration needs during travel or business trips.

The TEC portable refrigeration box is not only suitable for the daily medication management of diabetic patients, but also can be used for the transportation and storage of vaccines and samples.

1. Patient population: It is used for refrigerating insulin or other drugs that need to be stored at low temperatures during travel. Ensure that the medication remains within a safe temperature range throughout the journey to make patients feel more at ease when traveling.

2. Medical institutions: It is used for short-distance transportation of vaccines, antivenom sera or other medicines that need to be stored at low temperatures. It is especially suitable for scenarios such as vaccine distribution in rural areas and temporary vaccination site delivery.

3. Temporary preservation of biological samples: At the sampling site or during transportation, it is used for the temporary refrigeration of biological samples such as blood, urine, and tissue fluid to prevent sample deterioration due to high temperatures and ensure the accuracy of the test results.

4. Other groups: It is convenient for outdoor workers, emergency rescue personnel and other types of people to carry emergency medicines (which need to be stored at low temperatures) with them to ensure the safety of medication and enhance the medical support capacity in outdoor operation and rescue scenarios.

It can be seen from this that the TEC portable refrigeration box has played a significant role in the medical field. It not only solves the problem of constant-temperature storage of temperature-sensitive drugs such as insulin during transportation and use, but also provides a reliable guarantee for the transportation of vaccines, biological reagents and hormone-based drugs, ensuring that the drugs are always within a safe temperature range.
