Abstract

An adhesive coated sheet particularly shaped to facilitate the anchoring of a nasal-gastric tube to the nose of a patient to prevent accidental dislodgment thereof.

Claims

1. A device for anchoring a gastro-intestinal tube to the nose of a patient, comprising:

a planar sheet of flexible plastic material exhibiting a uniaxial stretch property along an easy stretch axis and a compliance modulus irrespective of thickness in the range of from 0.5 to 110 pounds per inch and an elastic recovery less than 98%, said sheet being bilaterally symmetrical and including a concave, arcuate, upper edge extending generally transverse to said easy stretch axis and first and second notches downwardly displaced from said upper edge with one edge of each of said notches being inwardly and downwardly sloping and the notches extending inwardly toward the center of said sheet from the opposed side edges of said sheet to define therebetween a medial strip of a predetermined length and width dimension corresponding to the outer diameter of the tube to be anchored, said medial strip being aligned with said easy stretch axis, said planar sheet being coated on one major surface thereof with a biocompatible adhesive material.

2. The device as in claim 1 and further including a removable backing sheet of release paper adhered to said adhesive coating.

3. A device for anchoring a length of medical tubing in the nose of a patient comprising:

(a) a planar sheet of flexible plastic material which is bilaterally symmetrical and exhibits a uniaxial stretch property along an easy stretch axis and a compliance modulus irrespective of thickness in the range of from 0.5 to 110 pounds per inch and an elastic recovery less than 98%, said sheet including a generally T-shaped tube engaging zone integrally joined to a nose engaging zone where the stem portion of said T-shaped zone is medially aligned with said nose engaging zone and extends along said easy stretch axis and the cross portion of said T-shaped zone extends transverse to said easy stretch axis, said nose engaging zone including an upper concave edge extending transverse to said easy stretch axis and a lower edge sloping downwardly and inwardly from the opposed side edges of said nose engaging zone to meet with said stem portion of said T-shaped zone; and

(b) a layer of non-allergenic, pressure-sensitive adhesive adhered to said planar sheet on one major surface thereof.

4. The device as in claim 3 and further including a layer of release paper adhered to said adhesive layer and coextensive therewith.

5. The device as in claim 4 wherein said layer of release paper is divided into plural segments, one segment being coextensive with said T-shaped tube engaging zone and two additional segments being co-extensive with said nose engaging zone.

6. The device as in claim 3 wherein said plastic sheet comprises a nonwoven polymeric material pervious to air and moisture.

7. The device as in claim 3 wherein said non-allergenic adhesive is selected from a class including polymethacrylate, polyvinyl ethyl ether, polyacrylate and acrylic ester copolymer.
