Abstract
A container, a wound dressing, and a wound dressing assembly are disclosed. The container may include one or more optical patterns that facilitate determining whether the container has been tampered with using an optical reader. The wound dressing may include one or more optical patterns that facilitate determining whether a stretchable substrate thereof is in a correctly-tensioned state using the optical reader. The wound dressing assembly may include multiple optical patterns that facilitate determining whether a cover of the wound dressing assembly is correctly positioned on a wound dressing of the wound dressing assembly using the optical reader.
Claims14
A container for a medical device, the container comprising:
- a base for holding the medical device;
- a cover configured to be coupled with the base;
- a locking piece for locking the cover to the base;
- and
- multiple optical patterns disposed on at least one of the base, the cover, or the locking piece;
- wherein, when the container is closed and the locking piece is locked, the multiple optical patterns form a combined optical pattern readable by an optical reader to obtain a first information, and
- wherein, when the container is opened and unlocked after being closed and locked, the multiple optical patterns are unreadable by the optical reader.
A wound dressing assembly, the wound dressing assembly comprising:
- a wound dressing;
- a cover configured to be attached to the wound dressing;
- multiple optical patterns disposed on at least one of the wound dressing or the cover;
- wherein, when the cover is correctly attached to the wound dressing, the multiple optical patterns form a combined optical pattern that is readable by an optical reader to obtain a first information, and
- wherein, when the cover is incorrectly attached to or detached from the wound dressing, the multiple optical patterns are unreadable by the optical reader.
A container for a medical device, the container comprising:
- a base for holding the medical device;
- a cover configured to be coupled to the base;
- a locking piece for locking the cover to the base;
- and
- an optical pattern disposed or disposable on at least one of the base, the cover, or the locking piece, wherein the optical pattern encodes a first information;
- wherein, when the container is closed and the locking piece is locked, the optical pattern is readable by an optical reader to obtain the first information, and wherein, when the container is opened and unlocked after being closed and locked, the optical pattern is modified to a modified optical pattern, the modified optical pattern having at least one characteristic different from the optical pattern.
A wound dressing comprising:
- a stretchable substrate comprising an under-tensioned state, a correctly-tensioned state, and an over-tensioned state, the stretchable substrate being configured to be transitioned between the under-tensioned state, the correctly-tensioned state, and the over-tensioned state;
- and
- a first optical pattern disposed on the stretchable substrate and encoding a first information, wherein the first optical pattern is readable by an optical reader in the correctly-tensioned state of the stretchable substrate to obtain the first information, and wherein the first optical pattern is unreadable by the optical reader in each of the under-tensioned state and the over-tensioned state of the stretchable substrate.
