Description

Drug temperature control device

The present invention relates to a drug temperature control device, and more particularly to a temperature control device that allows a drug stored in an injection pen to be maintained at an appropriate temperature.

At present, there is an injection pen that allows patients to select a drug dose and inject it, such as an insulin injection pen, to help chronic patients treat themselves at home. However, some drugs placed in areas that are too cold or too hot may cause the drug to deteriorate and become inactive. Taking insulin as an example, when it is in a high temperature environment (>30 degrees Celsius), it will be coagulated, and the precipitation will be deactivated and inactivated. If insulin is stored above 30 degrees Celsius, it may cause blood sugar to lose control. Therefore, once the insulin is opened, it should be stored at room temperature, preferably no more than 25 ° C, such as lockers or shade. In addition to temperature factors, insulin can not be exposed to sunlight for a long time. If you are traveling, it is best to keep the insulin in an ice bucket or a cold bag.

The insulin injection pen of the prior art usually has a cover which prevents the insulin stored in the refill from being directly exposed to light, but if it is outdoors for a long time or in a high temperature area, insulin is still difficult to maintain at room temperature. In addition, insulin injection pens are not suitable for placement. In ice buckets or cold bags, this is because changes in temperature will affect the life and accuracy of the pen.

The purpose of this creation is to solve the problem that the conventional drug injection pen cannot ensure that the drug is always maintained at a suitable temperature (such as room temperature), and that the injection pen cannot be placed in an ice bucket or a cold bag.

The present invention provides a drug temperature control device for controlling the temperature of a drug stored in an injection pen, comprising a housing, a temperature sensor, a temperature control component, a heat dissipation component, a cold junction component, and a control a circuit board having a chamber accommodating a portion of the injection pen and having at least one venting aperture; the temperature sensor being disposed in the chamber adjacent to the injection pen for measuring the drug The temperature control component is disposed in the chamber, and has a uniform cold end and a heat dissipating end; the heat dissipating component is disposed at the heat dissipating end and adjacent to the venting hole; the cold conducting component is disposed at the refrigerating end And surrounding the portion of the injection pen; the control circuit board is electrically connected to the temperature sensor and the temperature control component for driving the temperature control component according to the temperature value measured by the temperature sensor .
