Injektionsärmel

Injektionsärmel, also known as injection sleeves or ports, are medical devices designed to facilitate repeated access to the circulatory system for the administration of medications, fluids, or for the withdrawal of blood. They are typically implanted subcutaneously, meaning under the skin, and consist of two main components: a port reservoir and a catheter. The port reservoir is a small, self-sealing septum that can be accessed with a special non-coring needle. The catheter is a thin tube that connects the port reservoir to a vein.

The primary purpose of an injektionsärmel is to provide a reliable and convenient route for long-term therapy. This is particularly useful for patients requiring frequent intravenous treatments, such as chemotherapy, antibiotic therapy, or parenteral nutrition. By avoiding repeated venipunctures, injektionsärmel can reduce patient discomfort, minimize the risk of vein damage, and decrease the likelihood of infection. The device is usually implanted during a minor surgical procedure and can remain in place for months or even years, depending on the patient's needs. Proper care and maintenance are essential to prevent complications such as infection, clotting, or dislodgement. Healthcare professionals are trained to insert the needle, administer treatment, and remove the needle, as well as to provide instructions for home care if applicable.
