Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary products, in particular to an enhanced CT examination contrast agent extravasation alarm device. Background Art

[0002] Enhanced CT is actually to inject some contrast agents into the patient's veins on the basis of ordinary CT, so that the diseased area can be more clearly displayed. The purpose of enhanced CT is to strengthen the contrast between the lesion and the surrounding tissue, which is more conducive to the discovery of the lesion. At the same time, it can more clearly show the scope and nature of the lesion, and provide more and clearer information for radiologists, which is conducive to making a diagnosis of the disease and reducing missed diagnoses and misdiagnoses. During enhanced CT scanning, contrast agents are injected into the patient's veins through a syringe. Due to various reasons, contrast agents may leak from blood vessels into the surrounding soft tissues at the injection site, which is called contrast agent extravasation. The extravasated contrast agent will cause an increase in local tissue osmotic pressure, resulting in swelling, pain, numbness, and even ulceration and necrosis of subcutaneous tissue.

[0003] Currently, during enhanced CT examinations, when contrast agents are injected, doctors often observe the area around the injection site to determine whether extravasation of contrast agents has occurred. However, some patients will experience swelling of the skin in the early stages of extravasation, but the color of the skin has not changed. Therefore, doctors may not be able to detect extravasation of contrast agents for a while, which may cause adverse reactions in patients. Utility Model Content
