Abstract

A stabilizing device (and method of use) for insertion and maintenance of a catheter or cannula maintains a sterile insertion site and is simple and easy to construct and use, yet optimally maintains the catheter or cannula in place. A first stabilizing element includes a pair of bilateral wings and a catheter or cannula receiving element generally between the wings. A proximal stabilizing element—desirably two distinct and spaced pieces of tape—is operatively connected to the wings and has a sterile adhesive for affixing the wings to a patient to provide stability during needle removal and substantially for the duration that the catheter or cannula is inserted into a patient. A lateral stabilizing element—desirably two pieces of tape—is distinct and spaced from the proximal stabilizing element, to provide primarily lateral and medial stability to a catheter or cannula in a patient. A release sheet may cover the tape adhesive, or the tape may have a pattern of adhesive and non-adhesive sections cooperating with each other. Butterfly catheter, or angiocatheter, embodiments are particularly desirable.

Claims

1. A stabilizing device for insertion, using a needle, and maintenance of a catheter or cannula, comprising:

a first stabilizing element including a pair of bilateral wings and a catheter or cannula receiving element generally between said bilateral wings;

a proximal stabilizing element operatively connected to at least one of said bilateral wings and including a sterile adhesive with a release covering overlapping said at least one of said bilateral wings for affixing said at least one of said bilateral wings to a patient to initially provide stability of the catheter or cannula during needle removal and then provide stability against displacement substantially for the duration that the catheter or cannula is inserted into a patient;

a lateral stabilizing element distinct and spaced from said proximal stabilizing element, said lateral stabilizing element including a sterile adhesive with a release covering overlapping said at least one of said bilateral wings for affixing said at least one of said bilateral wings to a patient to provide primarily lateral and medial stability to the catheter or cannula in a patient; and

wherein said proximal stabilizing element comprises at least first and second distinct and spaced tape strips with a pressure sensitive sterile adhesive with the release covering on portions thereof proximally overlapping said bilateral wings, one of said tape strips operatively connected to each of said bilateral wings.

2. A device as recited in claim 1 wherein said lateral stabilizing element comprises at least third and fourth distinct and spaced tape strips with a pressure sensitive sterile adhesive with the release covering on portions thereof laterally overlapping said bilateral wings, one of said at least third and fourth tape strips operatively connected to each of said bilateral wings.

3. A device as recited in claim 2 wherein said release coverings comprise separate release sheet coverings overlapping adhesive on each of said tape strips to maintain sterility;

and further comprising an adhesive free portion at an edge of each of said tape strips to facilitate removal thereof after affixation to a patient'"'"'s skin.

4. A device as recited in claim 2 wherein at least one of said tape strips has a bottom surface with a pattern of the pressure sensitive adhesive and release sections, and is folded over on itself so that said adhesive and release sections operatively engage each other to maintain sterility until unfolded to be affixed to a patient'"'"'s skin.

5. A device as recited in claim 2 further comprising at least fifth and sixth distinct and spaced distal tape strips, one of said at least fifth and sixth tape strips operatively connected to each of said bilateral wings and having a portion thereof with a pressure sensitive sterile adhesive with a release covering distally overlapping a wing.

6. A device as recited in claim 2 wherein said proximal and lateral stabilizing elements consist essentially of said first through fourth tape strips.

7. A device as recited in claim 2 with said release coverings removed and in stabilizing contact with a patient'"'"'s body, said pressure sensitive adhesives of said tape strips for adhesive contact with the patient'"'"'s body to proximally and laterally stabilize said wings for contact with the patient'"'"'s body.

8. A device as recited in claim 1 in combination with an angiocatheter or butterfly catheter received by said catheter or cannula receiving element.

9. A device as recited in claim 1 wherein said receiving element comprises a substantially tubular hub or base, and the catheter extending proximally from said hub or base;

and in combination with a catheter insertion device having the needle extending through said hub or base and catheter.

10. A device as recited in claim 1 wherein said tape strips have non-adhesive portions thereof facilitating removal of said tape strips from a patient'"'"'s skin when desired.

11. A device as recited in claim 1 wherein said first stabilizing element is non-adhesive.

12. A device as recited in claim 1 wherein said first stabilizing element is of medical grade plastic.

13. A device as recited in claim 1 wherein said first stabilizing element is of rigid material.

14. A device as recited in claim 13 wherein said first stabilizing element is non-adhesive.

15. A device as recited in claim 1 wherein said first stabilizing element is of semi-flexible material.

16. A device as recited in claim 15 wherein said first stabilizing element is non-adhesive.

17. A device as recited in claim 1 wherein said tape strips of said proximal stabilizing element are substantially parallel to the catheter or cannula received by said catheter or cannula receiving element.

18. A device as recited in claim 17 wherein said first stabilizing element is non-adhesive.

19. A device as recited in claim 1 wherein said receiving element comprises a substantially tubular hub or base, and the catheter extending proximally from said hub or base;

and wherein said tape strips of said proximal stabilizing elements are substantially parallel to said catheter received by said hub or base.
