Publication number: 20240165317Abstract: A dressing interface includes a base that has an aperture and a plurality of microneedles that are attached to the base and disposed over the aperture. The interface also includes a port that is configured to receive a fluid conductor and a conduit that couples the port and the aperture. Each of the microneedles contains a passageway that is fluidly coupled to the aperture. The interface may be used with a drape that is placed over a tissue site. The interface may provide communication between the tissue site and a reduced-pressure source through the microneedles piercing the drape rather than by cutting a hole in the drape.Type: ApplicationFiled: January 30, 2024Publication date: May 23, 2024Inventor: Prathamesh Madhav KHARKAR
