Disposable absorbent stoma pad for gastrostomy
An absorbent stoma pad for encapsulating an external bolster of a feeding tube is provided. The stoma pad includes an upper layer, base layer, absorbent material, and cavity. The upper layer, which includes an upper surface and a lower surface, contains a centrally located opening with respect to a periphery of the upper layer, wherein the opening is configured to receive a tube portion of the feeding tube. The base layer, which includes an upper surface and a lower surface, contains a centrally located opening with respect to a periphery of the base layer, wherein the opening is also configured to receive the tube portion of the feeding tube. Meanwhile, the absorbent material is disposed adjacent the upper layer's lower surface. Further, the cavity permits airflow between the absorbent layer and the base layer when the external bolster is encapsulated by the stoma pad and positioned within the cavity.
