Abstract

A securing system includes a simply-structured device which permits medical tubing or other elongated medical devices to be easily secured to a patient, desirably without the use of tape or needles and suturing. The securing system includes a fitting having one or more flexible arms which secure the medical tubing to the fitting. The securing system may also include a retainer having a flexible anchor pad with an adhesive bottom surface, which can be attached to the patient'"'"'s skin. The fitting can be mounted to the retainer, for example, by inserting posts of the retainer through holes of the fitting. Advantageously, the securing system can be attached anywhere along the length of the tubing and can be applied to tubing of any size. Further, the system is simply to instal and easy to apply.

Claims

1. A fitting for securing a medical tubing to a patient comprising at least one flexible arm, the flexible arm having two sides, at least a portion of one of the sides including an adhesive layer arranged to make contact with the medical tubing and to attach the flexible arm to the medical tubing, and a fitting coupling structure connected to the flexible arm to attach the fitting to the patient, the fitting coupling structure including a pair of apertures for attaching the coupling structure to the patient and the at least one flexible arm being attached to the fitting coupling structure independent of the pair of the apertures.

2. The fitting of claim 1 further comprising two flexible arms joined in a generally V-shaped configuration.

3. The fitting of claim 2, wherein the fitting coupling structure is constructed from a material more rigid than the flexible arms, and the fitting coupling structure is connected proximate the intersection of the two flexible arms.

4. The fitting of claim 3, wherein the pair of apertures extends completely through the fitting coupling structure.

5. The fitting of claim 4, wherein the apertures are sufficiently closely spaced from an edge of the fitting coupling structure so as to allow the fitting to be sutured to the patient.

6. The fitting of claim 4, wherein the apertures are sized and configured to accept one or more posts to allow the fitting to be mounted to a retainer.

7. The fitting of claim 1, wherein the fitting coupling structure is constructed from a material more rigid than the flexible arm, and the fitting coupling structure is connected proximate one end of the flexible arm.

8. The fitting of claim 7, further comprising one or more apertures extending through the fitting coupling structure.

9. The fitting of claim 8, wherein the apertures are sufficiently closely spaced from an edge of the fitting coupling structure so as to allow the fitting to be sutured to the patient.

10. The fitting of claim 8, wherein the apertures are sized and configured to accept one or more posts and allow the fitting to be mounted to a retainer.

11. The fitting of claim 1, wherein the flexible arm extends from the fitting coupling structure at an acute angle relative to a line passing through the centers of the pair of apertures.

12. The fitting of claim 1, wherein the diameter of each of the pair of apertures is smaller than a width of the flexible arm.

13. A fitting for attaching a medical tubing to a patient, the fitting comprising:

at least one flexible arm comprised of a first layer of generally flexible material configured to extend around a portion of the medical tubing, and a second layer covering at least a portion of the first layer, the second layer comprising a medical-grade adhesive and being positioned to contact at least a portion of the medical tubing to allow the fitting to be attached to the medical tubing, and a fitting coupling structure including two or more apertures for attaching the coupling structure to the patient, at least the first layer of the one or more flexible arms connected to the fitting coupling structure independent of the two or more apertures.

14. The fitting of claim 13, further comprising a third layer releasably attached to the second layer, wherein the third layer comprises a releasable backing layer.

15. The fitting of claim 13, wherein the apertures are sufficiently closely spaced from an edge of the fitting coupling structure so as to allow the fitting to be sutured to the patient.

16. The fitting of claim 13, wherein the apertures are sized and configured to accept one or more posts and allow the fitting to be mounted to a retainer.

17. The fitting of claim 13, wherein the fitting coupling structure is constructed from a material that is more rigid than the flexible first layer.

18. The fitting of claim 13, wherein the diameter of the apertures is smaller than a width of the flexible arm.

19. A method of attaching medical tubing to a patient, comprising the steps of:

providing a fitting including one or more flexible arms, each of the flexible arms having two sides and an outer end, at least a portion of one of the sides including an adhesive for attaching the flexible arm to the medical tubing, and a fitting coupling structure connected to the flexible arms, the fitting coupling structure including one or more apertures to couple the medical tubing to the patient;

wrapping the arm about the medical tubing to attach the fitting to the medical tubing with the other end of the arm adhered to the medical tubing; and

securing the fitting to the patient in the desired location using the one or more apertures by inserting a structure through the aperture, the structure being attached to the patient.

20. A fitting for securing a medical tubing to a patient comprising a pair of flexible arms joined in a generally V-shape configuration having an inner edge that defines an inner vertex between the flexible arms, and having a fitting coupling structure, said fitting coupling structure being at a location spaced apart from the inner vertex with each arm extending outward from a base of the V-shaped configuration, each flexible arm having two sides, at least a portion of one of the sides including an adhesive layer arranged to make contact with the medical tubing and to attach the flexible arm to the medical tubing, and a fitting coupling structure connected to and extending entirely across a length of the base of the V-shaped configuration, the fitting coupling structure being more rigid than the flexible arms so as to reinforce the base of the V-shaped configuration.

21. The fitting of claim 20, wherein the inner vertex formed an angle of about ninety degrees between the flexible arms.
