DETAILED DESCRIPTION OF THE INVENTION

[0054] Referring to the drawings FIG. 1-6, embodiments of the present disclosure are illustrated.

[0055] FIG. 1 shows wound treatment device 10 made up of deployment system 20 and eye shield assembly 30 according to an embodiment. Under this embodiment, wound treatment device 10 allows a user to deploy the system's therapeutic agent (e.g. foaming synthetic polymer) onto the periorbital and/or orbital area of an injured patient (not shown). To do so, the user first assembles the system by removing cap 22 and reversibly connecting tubing 24 to eye shield assembly 30. The user then removes nonstick backing 32 from eye shield assembly 30 by utilizing nonstick backing tab 33. Eye shield assembly 30 is then positioned onto the patient, such that its adhesive area adheres to the periorbital area around the patient's injured eye. These two first steps may be reversed under some embodiments, such that tubing 24 is connected to eye shield assembly 30 after eye shield assembly 30 has been placed upon the patient, depending on caregiver preference and/or user characteristics.

[0056] The user next deploys the system's therapeutic agent (e.g. foaming synthetic polymer) by, under this embodiment, pushing on canister adapter 26 of canister 25 to deliver therapeutic agent to the patient. The therapeutic agent travels from inside canister 25 through tubing 24 to eye shield assembly 30. Eyelets 34 allow excess therapeutic agent (e.g. gas and polymer) to leave the inside chamber of eye shield assembly 30 without allowing significant buildup of pressure to damage the patient's eye underneath (not shown).

[0057] After deployment, the user may disconnect tubing 24, if so desired, to facilitate patient ambulation and/or transport.

[0058] Referring now to FIG. 2, one embodiment of deployment system 20 is shown. In this embodiment, cap 22 has been removed and tubing 24 connected to canister adapter 26 via female luer lock 27. Under many embodiments, cap 22 has a means for determining if it has been previously opened (i.e. tampered with). Under some embodiments, there is an additional seal to maintain sterility within cap 22 until use. On the other end of tubing 24 is male luer lock 28, which can connect to eye shield assembly 30 (not shown in this figure).

[0059] Referring now to FIGS. 3-4, one embodiment of eye shield assembly 30 is shown via top views. The female eye shield luer lock 36 allows reversible connection to male luer lock 28 and tubing 24 (both not shown in these figures) to allow polymer delivery to the inner chamber of eye shield assembly 30 and thus the patient. Eyelets 34 allow gas and excess polymer to leave the inside chamber of eye shield assembly 30 without allowing significant buildup of pressure to damage the patient's eye underneath (not shown). Nonstick backing tab 33 allows the user to remove nonstick backing 32 from eye shield assembly 30 to expose adhesive to connect the device to a patient. Foam layer 38 provides a soft surface to allow the device to contour to the patient's face, while connecting the transparent eye shield 39 to the lower adhesive layer (not shown).

[0060] Referring now to FIGS. 5-6, one embodiment of eye shield assembly 30 is shown via bottom isometric views. Nonstick backing 32 can be removed by the user via nonstick backing tab 33. Eyelets 34 allow direct connection between the inner chamber of eye shield assembly 30 and the external environment. Diffuser 37 ensures that foam delivered into the chamber is appropriately spread over the patient's orbital and periorbital structures within it, while minimizing the pressure delivered to these areas. Foam layer 38 provides a soft surface to allow the device to contour to the patient's face, while connecting eye shield 39 to adhesive layer 40. FIG. 6 shows an exploded view of the separate layers of eye shield assembly 30 (e.g. during manufacture). Under many embodiments, the therapeutic agent is delivered gently enough that there is no need for diffuser 37, which is not present in those embodiments.
