  • Patent number: 11278679
    Abstract: A medical wetness sensing device includes a cover, a first and second electrically conductive portions housed in the cover, an electrically insulative portion housed in the cover, and a compressible portion. The cover defines an outer surface. The first and second electrically conductive portions are exposed along an inner surface of the device. The first and second electrically conductive portions are configured to transmit a test signal indicating an absence or presence of a liquid on the inner surface. The electrically insulative portion electrically isolates the first electrically conductive portion from the second electrically conductive portion. The compressible portion is flexible, compressible, and configured such that the inner surface of the device is conformable to skin of a wearer of the device. The compressible portion is formed by at least one of the cover, the first and second electrically conductive portions, and the electrically insulative portion.

  • Patent number: 11260156
    Abstract: A sorbent canister utilized when performing a dialysis treatment during hemodialysis (HD) or peritoneal dialysis (PD) is provided. The sorbent canister includes inlet and outlet ports that include a threaded interface for connection to inlet and outlet tubes for circulation of dialysate through the sorbent canister. Upon disconnection from a dialysis machine, a pressure relief cap can be threaded onto the threaded interface to seal the fluid in the sorbent canister while allowing for off-gases to be expelled when a pressure within the sorbent canister exceeds a threshold pressure, thereby preventing a rupture in the canister body. In one embodiment, the pressure relief cap includes a deformable insert with a hole formed therein that is closed in an uncompressed state and opened in a compressed state. In another embodiment, the pressure relief cap includes a diaphragm that mates with a feature of the inlet or outlet port.
