System and method for removing a protective cover from a medical instrument
View Patent ↗According to one embodiment of the invention, a system for removing a cover from a medical instrument includes a flexible cover configured to cover at least a portion of a medical instrument, an insertion element coupled proximate a first end of the flexible cover, a pair of substantially parallel perforations formed in the insertion element, a pair of substantially parallel score lines formed in the cover and aligned with the pair of substantially parallel perforations. A portion of the insertion element between the pair of substantially parallel perforations is removable from the insertion element and a portion of the flexible cover between the pair of substantially parallel score lines is removable from the flexible cover when a force is applied to the portion of the insertion element between the pair of substantially parallel perforations.
1. An apparatus comprising:
a flexible cover having a general tubular configuration for covering at least a portion of an elongated medical instrument;
an insertion element coupled proximate a first end of the flexible cover, the insertion element being selectively expandable from a closed position to an open position to facilitate insertion over the elongated medical instrument;
a first pair of tear lines formed in the insertion element; and
a second pair of tear lines formed in the cover and aligned with the first pair of tear lines, the second pair of tear lines extending from the first end to at least an intermediate portion of the flexible cover;
whereby the flexible cover and the insertion element may be separated along the second pair of tear lines and the first pair of tear lines respectively when a pulling force is applied to the second pair of tear lines and the first pair of tear lines.
2. The apparatus of claim 1 , wherein a second end of the flexible cover distal the first end is closed.
3. The apparatus of claim 1 , wherein a second end of the flexible cover distal the first end includes an aperture.
4. The apparatus of claim 1 , wherein a second end of the flexible cover distal the first end includes a scored or perforated portion adapted to produce an aperture in the second end when a force is applied to the scored or perforated portion.
5. The apparatus of claim 1 , wherein the second pair of tear lines extends from the first end to a second end of the flexible cover.
6. The apparatus of claim 1 , wherein the first pair of tear lines comprises two lines of perforations.
7. The apparatus of claim 1 , wherein the first pair of tear lines comprises two score lines.
8. The apparatus of claim 1 , wherein the second pair of tear lines comprises two lines of perforations.
9. The apparatus of claim 1 , wherein the second pair of tear lines comprises two score lines .
10. The apparatus of claim 1 , wherein the flexible cover is formed from an elastic polymer.
11. A medical device comprising:
a medical instrument;
a flexible cover having a general tubular configuration covering at least a portion of the medical instrument;
an insertion element coupled proximate a first end of the flexible cover and extending around an outer periphery of the medical instrument, the insertion element being selectively expandable from a closed position to an open position to facilitate insertion over the medical instrument;
a first pair of tear lines formed in the insertion element; and
a second pair of tear lines formed in the cover and aligned with the first pair of tear lines, the second pair of tear lines extending from the first end to at least an intermediate portion of the flexible cover;
whereby the flexible cover and the insertion element may be separated along the second pair of tear lines and the first pair of tear lines respectively when a pulling force is applied to the second pair of tear lines and the first pair of tear lines.
12. The medical device of claim 11 , wherein the medical instrument is generally elongated in shape.
13. The medical device of claim 12 , wherein the medical instrument is selected from the group consisting of an endoscope, an ultrasound probe, a gamma probe, and a video camera.
14. The medical device of claim 11 , wherein a second end of the flexible cover distal the first end is closed.
15. The medical device of claim 11 , wherein a second end of the flexible cover distal the first end includes an aperture.
16. The medical device of claim 11 , wherein a second end of the flexible cover distal the first end includes a scored or perforated portion adapted to produce an aperture in the second end when a force is applied to the scored or perforated portion.
17. The medical device of claim 11 , wherein the flexible cover is formed from an elastic polymer.
18. A method for removing a cover from a medical instrument, comprising:
covering at least a portion of a medical instrument with a flexible cover, the flexible cover having an insertion element coupled proximate a first end of the flexible cover;
separating the insertion element along a first pair of tear lines by applying a pulling force to the first pair of tear lines;
separating the flexible cover along a second pair of tear lines by applying a pulling force to the second pair of tear lines; and
removing the flexible cover and the insertion element from the medical instrument.
19. The method of claim 18 , wherein separating the insertion element along a first pair of tear lines, further comprises separating the insertion element along a pair of perforations.
20. The method of claim 18 , wherein separating the flexible cover along a second pair of tear lines, further comprises separating the flexible cover along a pair of score lines that extends from the first end to a second end of the flexible cover.
