Film Sheath with Built-In Flange that Allows for Easy and Secure Attachment or Bonding
A probe cover is provided. The probe cover is formed from a film that defines a tubular sheath having a distal end and a proximal end defining a channel therebetween, where the distal end is closed and the proximal end defines an opening having a periphery; and a flange that extends from the periphery of the opening at the proximal end of the tubular sheath. The flange facilitates the secure attachment of the probe cover to a surgical drape, such as a surgical drape used in the operating room as an anesthesia screen or as a screen to separate the surgical sterile field from the non-sterile field. A method of using the probe cover in conjunction with a probe during a surgical procedure is also provided, where the method includes attaching the probe cover to a surgical drape. A surgical drape that includes the probe cover is further provided.
1 . A probe cover formed from a film, wherein the film defines: (a) a tubular sheath having a distal end and a proximal end defining a channel therebetween, wherein the distal end is closed and the proximal end defines an opening having a periphery; and (b) a flange extending from the periphery of the opening at the proximal end of the tubular sheath.
2 . The probe cover of claim 1 , wherein the flange is adapted to attach to a planar or semi-planar surface.
3 . The probe cover of claim 1 , wherein the tubular sheath and the flange are flexible.
4 . The probe cover claim 1 , wherein an adhesive is disposed on a non-sterile field facing surface of the flange or a sterile surgical field facing surface of the flange.
5 . The probe cover claim 4 , wherein a release liner is disposed on the adhesive.
6 . The probe cover of claim 4 , wherein the adhesive comprises a hot melt adhesive coating, an acrylic adhesive coating, a tape, or a combination thereof.
7 . The probe cover claim 1 , wherein the probe cover is configured for direct attachment to a surgical drape.
8 . The probe cover claim 1 , wherein the film is seamless.
9 . The probe cover claim 1 , wherein the film comprises latex, polyurethane, polyisoprene, polycarbonate, polypropylene, polyethylene, or a combination thereof.
10 . The probe cover claim 1 , wherein the flange extends from the periphery of the opening at the proximal end of the tubular sheath to opposing first and second edges and opposing third and fourth edges such that the flange has a square or rectangular shape.
11 . The probe cover claim 1 , wherein the flange has a surface area that is sufficiently large to cover an opening in a surgical drape to which the flange is attached.
12 . The probe cover claim 1 , wherein the channel receives a probe connected to a non-sterile medical instrument.
13 . The probe cover of claim 12 , wherein the probe is an ultrasound probe, an echocardiography probe, or an internal cardiac defibrillator wand.
14 . A method for using a probe in a sterile surgical field, wherein the probe is a component of a non-sterile medical instrument located in a non-sterile field, the method comprising:
a) positioning a probe cover adjacent a sterile surgical field side or a non-sterile field side of a surgical drape material, wherein the probe cover is formed from a film, wherein the film defines: (i) a tubular sheath having a distal end and a proximal end defining a channel therebetween, wherein the distal end is closed and the proximal end defines an opening; and (ii) a flange extending from the periphery of the opening at the proximal end of the tubular sheath;
b) attaching a non-sterile field facing surface of the flange to a sterile surgical field facing surface of the surgical drape material or attaching a sterile field facing surface of the flange to a non-sterile field facing surface of the surgical drape material; and
c) inserting the probe into the opening at the proximal end of the tubular sheath and into the channel from the non-sterile field, wherein the probe is connected to the non-sterile medical instrument via a cord such that the probe is encased by the tubular sheath.
15 . The method of claim 14 , wherein an adhesive is disposed on the non-sterile field facing surface of the flange or on the sterile surgical field facing surface of the flange.
16 . The method of claim 15 , wherein a release liner is disposed on the adhesive, wherein the release liner is removed prior to attaching the non-sterile field facing surface of the flange to the sterile surgical field facing surface of the surgical drape material or prior to attaching the sterile-field facing surface of the flange to the non-sterile field facing surface of the surgical drape material.
17 . The method of claim 14 , further comprising cutting an opening in the surgical drape material at a location where the flange is attached such that the opening at the proximal end of the tubular sheath lines up with the opening cut in the surgical drape material prior to or after step b).
18 . The method of claim 17 , wherein the flange has a surface area that is sufficiently large to cover the opening in the surgical drape material.
19 . The method of any one of claim 14 , further comprising d) advancing the probe contained within the channel and encased by the tubular sheath into the sterile surgical field for use on a patient.
20 . The method of any one of claim 14 , wherein the film is seamless.
21 . The method of any one of claim 14 , wherein the tubular sheath and flange are flexible such that the tubular sheath is movable in multiple planes within the sterile surgical field and such that the flange is attachable to a planar or semi-planar surface.
22 . The method of any one of claim 14 , wherein the probe is an ultrasound probe, an echocardiography probe, or an internal cardiac defibrillator wand.
23 . A surgical drape for separating a sterile surgical field from a non-sterile field, the surgical drape comprising:
a surgical drape material having an opening formed therein; and
a probe cover formed from a film, wherein the film defines: (a) a tubular sheath having a distal end and a proximal end defining a channel therebetween, wherein the distal end is closed and the proximal end defines an opening having a periphery; and (b) a flange extending from the periphery of the opening at the proximal end of the tubular sheath, wherein the probe cover opening is aligned with the surgical drape material opening, wherein the probe cover is attached to the surgical drape material via the flange.
