Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an ice pack device for drug extravasation. Background Technology

[0002] In clinical treatment, hypertonic or vasoactive drugs are sometimes administered intravenously. These types of drugs can irritate the blood vessel walls or cause extravasation due to osmotic pressure differences during intravenous injection. Extravasation can lead to swelling in the injection site, and in severe cases, tissue necrosis. Therefore, when swelling occurs, timely ice application is necessary. Constricting vasoconstrictors reduces drug diffusion and can relieve swelling and patient pain. Current ice application methods involve fixing an ice pack to the swollen area with a towel. This method suffers from uncontrollable ice temperature. Initially, the ice pack is too cold, potentially causing frostbite due to low local skin temperature. As the application time increases, the melting temperature of the ice pack gradually rises, rendering it ineffective. Therefore, a device for treating drug extravasation is needed to address these issues. Summary of the Invention

The push rod pushes the edge of the cold compress to fit with the patient's skin, so that the cold compress can fit better with the patient's skin and improve the cold compress effect.
