Description

Technical Field

[0001] The present application relates to the technical field of dressing change materials, and more specifically, to a dressing change material for an infusion port. Background Art

[0002] An intravenous infusion port, also known as an implantable drug delivery device, is a fully implantable vascular access system. It is a central venous access established by subcutaneously implanting the port body and connecting it to a catheter, providing patients with a long-term intravenous drug delivery route. When patients require intravenous medication, they must use a non-invasive needle kit for puncture and infusion. However, the butterfly needle is generally fixed with a transparent infusion port dressing.

[0003] In the related art, after puncturing the infusion port, the butterfly wing needle needs to be supported by a dressing. The patent with the prior art publication number CN215652022U provides an anti-needlestick infusion port needle fixing dressing, including a dressing bonding mechanism. The dressing bonding mechanism includes a small annular dressing for bonding to the patient's skin surface. The small dressing is made of soft transparent material. Through the small dressing, puncture opening, infusion port needle and small grasping wings, it is convenient for personnel to manually grasp the small grasping wings and insert the infusion port needle through the interlaced opening. The circular hole opened in the middle of the small dressing is convenient for medical staff to puncture accurately into the injection seat of the infusion port, and at the same time, the skin condition around the puncture point of the infusion port can be well evaluated.

[0004] While the aforementioned existing technical solutions facilitate manual insertion of the port needle through the provision of a small dressing, puncture opening, port needle, and small gripping wings, they still suffer from the following drawbacks: 1. The aforementioned port dressing is not convenient for securing the two wings of the needle, posing a risk of movement after puncture, and cannot guarantee the sterility of the interface between the port needle and the skin. 2. Currently, all medical dressings are flat, and when securing the raised steel needle, a large gap will exist at the point of contact with the skin, which is prone to generating water vapor. Evaporated sweat can breed bacteria inside, making infection more likely, and the dressing is also prone to curling.

[0005] In view of this, we proposed changing the dressing of the infusion port. Utility Model Content
