Description

FIELD OF THE INVENTION

The present invention relates to a system and method for treating wounds and closed incisions from surgical procedures.

BACKGROUND OF THE INVENTION

Healing from wounds and prevention of scarring, such as from incisions encountered during surgical procedures, quickly and safely are important to the treatment process. Commonly used to protect wounds and closed incisions from contamination are dressing such as fabric bandages. A drawback of such dressings is that during removal of the dressing, the fabric may stick to the tissue and reopen the wound.

In some instances, silicone dressings are used to cover a wound or closed incision to aid in healing. Such silicone dressings are dressings coated with soft silicone as an adhesive or a wound contact layer. The intrinsic properties of soft silicone are such that these dressings may be removed without causing trauma to the wound, closed incision, or to surrounding skin. Published studies suggest that patients whose wounds or closed incisions are dressed with soft silicone dressings experience less trauma, less discomfort on removal and less maceration than those dressed with conventional dressings, thus reducing treatment costs.

As discussed, a benefit of silicone dressings is that it will not stick to the wound or closed incision, or cause trauma to the treatment site when removed. However, this benefit also results in a shortcoming of silicone dressings that has not been addressed due to the generally poor adherence of the dressing to the patient's skin. This is especially the case with incisions in certain places on the body that are prone to causing high tension areas on the dressing, such as a shoulder, elbow or knee. It is sometimes the case that the silicone dressing will release from the patient's skin.

SUMMARY OF THE INVENTION

For wound or post-surgical closed incision treatment, a silicone sheet may be applied directly over a wound or an incision site. The silicone sheet may be provided with a backing, which, when removed, exposes an adhesive layer. In order to better secure the silicone sheet to the site, adhesive anchors may be applied over a portion of the silicone sheet when the silicone sheet is positioned in place. For example, in the example of a surgical procedure in the shoulder area, the silicone sheet section may be placed over the site, an adhesive anchor may be placed at one end of the silicone sheet section, and then a second adhesive anchor placed over a portion of the silicone sheet between the ends, and particularly in a higher tension area, and a third adhesive anchor placed over a second end portion of the silicone sheet section.

Some aspects of the present invention relate to a dispenser for the silicone sheeting and the adhesive anchors. The dispenser provides several advantages. The silicone sheeting is provided in the form of a roll, which includes a leader, which is preferably made of a foil material. The leader allows for easier dispensing of the silicone sheeting. The silicone sheeting may be cut from the roll by way of a scissors or other separate cutting implement, or may be cut with a cutting surface integral with the dispenser. Another advantage relates to selectable displays, such as for displaying UPC codes. Different jurisdictions often have different labelling standards. In many instances this requires suppliers to either have different printed boxes for different jurisdictions, or create separate labels to affix to packaging for different jurisdictions.

According to a preferred embodiment of the present invention, the wound or closed incision treatment system comprises a dressing dispenser unit and an adhesive anchor dispensing unit. With each of the dressing dispenser unit and the adhesive anchor dispensing unit, the dispensing units include a case that defines an interior. The case also defines an aperture through which the supply of silicone dressings or adhesive anchors is drawn. The silicone dressings are removably secured to a dressing backing ribbon. The adhesive anchors are also removably secured to an anchor backing ribbon. Each of the dressing backing ribbon and the anchor ribbon is preferably wrapped around its respective barrel member. Each barrel member may, in some embodiments, be mounted within either the dressing dispenser unit or anchor dispensing unit on a spindle that extends across opposed sidewalls thereof. The adhesive anchors are preferably precut into a desired shape or shapes. For example, anchors that are butterfly shaped may be preferred to secure certain areas, whereas, elongated shapes may be preferred in others. Fanciful or decorative shaped anchor members can also be used, such as diamonds, crescents, footballs, clover leafs, or the like. It may also be desirable to include graphic designs on the anchors to provide some aesthetic benefits and whimsy.

Each of the dressing backing ribbon and anchor ribbon may include a leader portion. The leader portion of the dressing backing ribbon is preferably extended through the dressing aperture and held by a dressing loop formed on the exterior of the dressing dispensing unit. Similarly, the leader portion of the anchor ribbon is preferably extended through the anchor ribbon aperture and held by an anchor loop formed on the exterior of the anchor dispensing unit.

The dispenser unit case for either or both of the silicone dressing and the adhesive anchors may preferably include a plurality of sides defining an open end and a closure system for closing the open end. The closure system preferably includes a first flap member configured to occlude the open end. The first flap member may be hinged with the body about the open end. The first flap member also includes a tab member. A second flap member is also provided. This second flap member is also configured to occlude the open end, may be hinged with the body about the open end, and may include a tab member. Formed proximate the open end is a first slot and a second slot. In some embodiments, the first slot member may be formed in the second flap member or adjacent thereto, and the second slot member may be formed in the first flap member or adjacent thereto. The first tab is adapted to be received in the second slot, and the second tab is adapted to be received in the first slot. Since either of the first flap member or second member may close the open end, different printing may be placed on the exterior portions of the first and second flap members, respectively, such that a single printing run can incorporate different visible markings, if desired. For example, different jurisdictions may have different labeling requirements. By having a single printed box be adaptable to displaying different markings, a suppler is able to reduce packaging inventories.

In another embodiment, it may be desirable to have a single dispensing unit for both the silicone dressings and the anchors. In such an embodiment, the dispenser unit defines an interior, a silicone dressing aperture, and an adhesive anchor aperture. As with the previous embodiment, a dressing backing ribbon including a plurality of silicone dressings removably secured thereto is provided, and the dressing aperture is sized to allow a portion of the dressing backing ribbon to exit the dispenser unit. Also, an adhesive anchor backing ribbon is provided that includes a plurality of adhesive anchors, where each anchor having an adhesive backing and removably secured to the adhesive anchor backing ribbon. The adhesive anchor aperture is sized to allow a portion of the adhesive anchor backing ribbon to exit the dispenser unit.

In this embodiment, the dispenser unit includes a dressing loop formed on the exterior thereof that is aligned with the dressing aperture, and an anchor loop formed on the exterior thereof that is aligned with the anchor aperture. The dressing backing ribbon includes a leader portion, and the dressing loop is adapted to receive the leader portion of the dressing backing ribbon, and the adhesive anchor backing ribbon includes a leader portion, which is adapted to be received in the anchor loop.

In this embodiment, a dressing barrel member and an anchor barrel member, each defining an outer surface and an interior passage are provided. The dressing ribbon and the anchor ribbon are wrapped around the outer surface of their respective barrel, and the barrels are rotatably mounted on a spindle. A closure system may be provided similar to the closure system for the individual dressing dispensing unit or anchor dispensing unit.

The present invention may also include a drying system. Pieces of silicone sheeting may be washed and reused. A rack may be provided for drying the silicone sheeting.

According to a preferred method of using the silicone sheeting, a silicone sheet removed from the dressing ribbon and placed over a wound. For sake of example, an incision to a shoulder is discussed, because this is a high movement, high stress area for wound recovery. The silicone dressing is placed over the wound. If necessary, multiple dressings can be used. Anchor members may then be removed from the anchor ribbon. These are preferably placed at the ends of the silicone sheet and secured to the patient's skin. Additional anchors are placed at points along the silicone sheet, and particularly in high stress areas. In some embodiments, the anchors are formed of a stretchable material such that strain on the anchors is absorbed by stretch, such that they continue to adhere to the patient's skin and silicone sheet. The position of the silicone sheet between the adhesive anchor and the wound area prevents any trauma to the wound area.
