Abstract
Abstract An external anchoring system for securing medical tubing to a body includes a resilient receptor disposed upon the exterior of a tube to be anchored; means for attachment of the anchoring system to the body; means for linking connected to the means for attachment to the body; and a knoblet projecting from the means for linking. The resilient receptor provides a reversible interference fit for the knoblet. Preferably, the resilient receptor is one of a plurality of resilient receptors disposed longitudinally on the tubing. Also, a method for anchoring a non-inserted portion of a naso-gastric catheter to the nose of a patient is disclosed and includes the steps of providing a naso-gastric catheter having a resilient receptor; providing a link having a nose attachment on one end and a knoblet on the opposite end; attaching the link to the nose; and inserting the knoblet into the resilient receptor.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
187 words
An external anchoring system for securing naso-gastric tubing to a patient's nose, the system comprising: means for adhesive attachment to the patient's nose; nasogastric tubing including a first tube and a second tube longitudinally intermittently joined to the first tube to define at least one resilient receptor situated between the first tube and the second tube, said second tube being more resiliently yieldable than said first tube; means for reversible linking of the naso-gastric tubing to the means for adhesive attachment including a tether attachment having a main portion secured at a first end to the means for adhesive attachment and at a second end having a reduced diameter shank portion ending in a knoblet; means for removably inserting said knoblet in said receptor in an interference fit to secure the nasogastric tubing to the patient's nose, said means for removably inserting said knoblet comprising receipt of said knoblet through said receptor, and said reduced diameter shank portion being received within said receptor, whereby said knoblet and said main portion of said tether abut opposite sides of said receptor with said shank portion received within said receptor.
Claim 2
Dependent Claim
187 words
An external anchoring system for securing naso-gastric tubing to a patient's nose, the system comprising: means for adhesive attachment to the patient's nose; nasogastric tubing including a first tube and a second tube longitudinally intermittently joined to the first tube to define at least one resilient receptor situated between the first tube and the second tube, said second tube being more resiliently yieldable than said first tube; means for reversible linking of the naso-gastric tubing to the means for adhesive attachment including a tether attachment having a main portion secured at a first end to the means for adhesive attachment and at a second end having a reduced diameter shank portion ending in a knoblet; means for removably inserting said knoblet in said receptor in an interference fit to secure the nasogastric tubing to the patient's nose, said means for removably inserting said knoblet comprising receipt of said knoblet through said receptor, and said reduced diameter shank portion being received within said receptor, whereby said knoblet and said main portion of said tether abut opposite sides of said receptor with said shank portion received within said receptor.
Claim 3
Dependent Claim
31 words
The anchoring system of claim 1 and wherein the receptor is one of a plurality of resilient receptors longitudinally spaced apart along the tubing between said first and said second tube.
Claim 4
Dependent Claim
58 words
The anchoring system of claim 1 wherein the tubing comprises a first tube and a second tube external and parallel to the first tube, bonded together in at least two longitudinally spaced apart segments and wherein the resilient receptor is defined by the adjoining external walls of the unbonded segment between the two longitudinally spaced apart bonded segments.
Claim 5
Dependent Claim
23 words
The anchoring system of claim 3 wherein the resilient receptor is one of a plurality of resilient receptors longitudinally disposed along the tubing.
Claim 6
Dependent Claim
19 words
The anchoring system of claim 1 wherein the means for attachment to the body comprises a medical grade adhesive.
Claim 7
Dependent Claim
27 words
The anchoring system of claim 5 wherein the means for attachment to the body comprises a butterfly shaped adhesive tape adapted for application to a patient's nose.
Claim 8
Dependent Claim
13 words
The anchoring system of claim 1 wherein the means for linking is flexible.
Claim 9
Independent Claim
128 words
A method for anchoring a non-inserted portion of a naso-gastric catheter to the nose of a patient comprising the steps: providing a catheter having a first tube and a second more resilient tube longitudinally intermittently joined to the first tube to define at least one resilient receptor situated between the first tube and the second tube; providing an adhesive attachment for application to the patient's nose; providing a tether having a main portion, a reduced diameter shank portion, and a knoblet; connecting said tether main portion to said adhesive attachment; inserting said knoblet through said resilient receptor; and leaving said shank portion within said resilient receptor, whereby said knoblet and said tether main portion abut said resilient receptor on opposite sides with said shank disposed within the receptor.
Claim 10
Independent Claim
128 words
A method for anchoring a non-inserted portion of a naso-gastric catheter to the nose of a patient comprising the steps: providing a catheter having a first tube and a second more resilient tube longitudinally intermittently joined to the first tube to define at least one resilient receptor situated between the first tube and the second tube; providing an adhesive attachment for application to the patient's nose; providing a tether having a main portion, a reduced diameter shank portion, and a knoblet; connecting said tether main portion to said adhesive attachment; inserting said knoblet through said resilient receptor; and leaving said shank portion within said resilient receptor, whereby said knoblet and said tether main portion abut said resilient receptor on opposite sides with said shank disposed within the receptor.
Claim 11
Dependent Claim
40 words
The method of claim 8 further including the steps of providing a plurality of longitudinally disposed resilient receptors on the catheter and selecting a desirably located resilient receptor prior to inserting said knoblet and said shank portion into said receptor.
