Description

Technical Field

[0001] The utility model relates to the technical field of subcutaneous tunnel infection cleaning, in particular to a subcutaneous tunnel flushing device. Background Art

[0002] In hemodialysis treatment, a central venous catheter (CVC) is a commonly used vascular access, especially suitable for patients who are in urgent need of dialysis and have no time to establish arteriovenous fistulas or are unable to establish arteriovenous fistulas due to poor vascular conditions. However, factors such as long-term catheter indwelling, weak immune systems of maintenance hemodialysis patients, migration of skin flora, or underlying diseases are likely to cause catheter infections. Catheter infection is a common complication in CVC patients, manifested as redness, swelling, heat, pain at the catheter exit, and purulent secretions. In clinical work, many doctors will choose to perform tunnel flushing to clean and disinfect the secretions in the tunnel by flushing, so as to remove the transient bacteria in the tunnel. When necessary, local drug anti-inflammatory treatment can be carried out in the tunnel. However, the current nursing of catheter infections is relatively difficult, thus resulting in a decline in nursing efficiency. Content of the Utility Model
