Claims15
A canister for fluid collection, the canister comprising:
- a canister body configured to contain wound exudate collected from a wound site;
- and
- a plurality of superabsorbent projections fixed to and extending from at least a portion of an interior surface of the canister body, wherein the superabsorbent projections comprise a polymer in the form of granules and are configured to dissociate from the interior surface of the canister body while remaining intact such that the superabsorbent projections do not break down to individual granules, wherein the superabsorbent projections comprise a flexible plasticized hydrophilic polymer matrix having a substantially continuous internal structure.
A method of making a canister for fluid collection comprising:
- providing a canister body configured to contain wound exudate collected from a wound site;
- preparing a slurry comprising a superabsorbent material, wherein the slurry comprises a polymer in the form of granules;
- and
- applying the slurry onto an interior surface of the canister body in the form of a plurality of superabsorbent projections, wherein the superabsorbent projections are configured to dissociate from the interior surface of the canister body while remaining intact such that the superabsorbent projections do not break down to individual granules, wherein the superabsorbent projections comprise a flexible plasticized hydrophilic polymer matrix having a substantially continuous internal structure.
