1. A securement assembly for an enteral access device or vesical access device (“access device”), the securement assembly comprising:
a base configured to support an external port of the access device, wherein the base comprises a border rim and a central portion, wherein the border rim is configured to engage a skin surface of a patient around a stoma and the central portion is configured to engage the external port of the access device, wherein the central portion comprises opposing side arms defining an aperture through which a tube of the access device extends, wherein the side arms of the central portion are resiliently flexible to facilitate selective enhanced retention of the external port of the access device, wherein the central portion is a cantilevered extension from a rear of the base;
an absorbent member configured to be slid under the cantilevered extension and over the border rim into engagement with the skin surface around the stoma in an annular space defined between the border rim and the tube of the access device; and
a lid pivotably coupled to the base.
 
2. A securement assembly for an enteral access device or vesical access device (“access device”), the securement assembly comprising:
a base configured to support an external port of the access device, wherein the base comprises a border rim and a central portion, wherein the border rim is configured to engage a skin surface of a patient around a stoma and the central portion is configured to engage the external port of the access device, wherein the central portion comprises opposing side arms defining an aperture through which a tube of the access device extends, wherein the side arms of the central portion are resiliently flexible to facilitate selective enhanced retention of the external port of the access device, wherein the central portion is a cantilevered extension from a rear of the base;
an absorbent member comprising opposing wings configured to extend beyond lateral sides of the base and configured to be slid under the cantilevered extension and over the border rim into engagement with the skin surface around the stoma in an annular space defined between the border rim and the tube of the access device, and the absorbent member defining a central aperture and a slit, wherein the tube of the access device extends through the central aperture; and
a lid pivotably coupled to the base;
wherein at least one of the border rim and a border edge of the lid at the lateral sides of the base defines a notch to accommodate the opposing wings of the absorbent member.
 
22. A securement assembly for an enteral access device or vesical access device (“access device”), the securement assembly comprising:
a base comprising a border rim and a central portion, wherein the border rim is configured to engage a skin surface of a patient around a stoma and the central portion is configured to engage an external port of the access device, wherein the central portion comprises opposing side arms defining an aperture through which a tube of the access device extends, wherein the side arms of the central portion are resiliently flexible to facilitate selective enhanced retention of the external port of the access device, wherein the central portion is a cantilevered extension from a rear of the base;
an absorbent member configured to be slid under the cantilevered extension and over the border rim into engagement with the skin surface around the stoma in an annular space defined between the border rim and the tube of the access device; and
a lid selectively detachably and pivotably coupled to the base.
 
23. A method of installing a securement assembly for an enteral access device or vesical access device (“access device”), the method comprising:
coupling a lid of the securement assembly to a base of the securement assembly, wherein the base comprises a border rim and a central portion, wherein the border rim is configured to engage a skin surface of a patient around a stoma and the central portion is configured to engage the external port of the access device, wherein the central portion comprises opposing side arms defining an aperture through which a tube of the access device extends, wherein the side arms of the central portion are resiliently flexible to facilitate selective enhanced retention of the external port of the access device, wherein the central portion is a cantilevered extension from a rear of the base;
after coupling the lid of the securement assembly to the base of the securement assembly, adhering the border rim of the base to the skin surface of the patient about the stoma of the patient;
sliding an absorbent member under the cantilevered extension and over the border rim into engagement with the skin surface around the stoma in an annular space defined between the border rim and the tube of the access device; and
supporting an external port of the access device by the central portion of the base.
