Adhesive support devices and methods of making and using them

An adhesive support device for holding a catheter to a patient's body, the device having a three-dimensional shape and comprising:

• a body portion comprising a sheet of material having an elastic modulus of greater than 0.4 GPa, wherein the sheet has been stamped from a flat plane to form:
• a first base region and a second base region, wherein the first and second base regions extend in the flat plane, the first and second base regions each having a first thickness, and
• a cavity region having an average wall thickness that is less than the first thickness, the first and second base regions extending from either side of the cavity region, wherein the cavity region extends out of the flat plane at an angle that is greater than 90° relative to an adjacent base region, the cavity region forming an open channel between the first and second base region through which a catheter may extend and one or more lateral openings into the open channel, further wherein a wall of the cavity region comprises a plurality of ridges;
• and
• a first adhesive substrate coupled to the first base region and a second adhesive substrate coupled to the second base region.

An intraosseus needle securement device stamped from a sheet of material into a three-dimensional shape, the device comprising:

• a body portion comprising a sheet of material having an elastic modulus of greater than 0.4 GPa, wherein the sheet has been stamped from a flat plane to form:
• a base region extending in the flat plane, the base region having a first thickness, and a hub region surrounded by the base region, the hub region having a maximum wall thickness that is equal to or less than the first thickness, wherein the hub region extends from the flat plane at an angle that is greater than 90° relative to an adjacent base region, the hub region having an opening configured to secure an intraosseus needle, and
• a plurality of ridges in the hub region extending from the base region towards the opening and configured to increase stability of the hub region relative to the base region;
• and
• an adhesive substrate coupled to the base region and configured to secure the device to a patient's skin.
