Abstract

A medical device assembly includes a catheter with a catheter hub, a housing, a first wing, and a second wing. The housing surrounds the catheter hub, but is spaced from the catheter hub to define a channel. The first wing includes a first hook disposed in the channel to permit rotation of the first wing about the catheter hub. The second wing includes a second hook disposed in the channel to permit rotation of the second wing about the catheter hub.

Claims

1. A medical device assembly, comprising:

a catheter, including a catheter hub;

a housing surrounding the catheter hub, the housing spaced from the catheter hub such that a channel is defined therebetween;

a first wing having a first hook disposed in the channel to permit rotation of the first wing about the catheter hub, the first wing extending from the catheter hub in a first direction; and

a second wing having a second hook disposed in the channel to permit rotation of the second wing about the catheter hub, the second wing extending from the catheter hub in a second direction opposite the first direction.

2. The medical device assembly according to claim 1, wherein the catheter includes a bevel rotationally aligned with the first wing when the first wing is in an insertion position.

3. The medical device assembly according to claim 1, further comprising an adhesive layer disposed on each of the first wing and the second wing.

4. The medical device assembly according to claim 1, wherein the catheter hub comprises a luer connector configured to connect the catheter hub with a medical line.

5. The medical device assembly according to claim 1, wherein the first wing is designed to rotate independently from the second wing.

6. The medical device assembly according to claim 1, wherein the first wing and the second wing are connected such that rotation of the first wing simultaneously rotates the second wing.

7. The medical device assembly according to claim 1, wherein the first wing and the second wing are spring-loaded to bias rotation of the first wing away from the second wing.

8. The medical device assembly according to claim 1, further comprising a handpiece including a slot, wherein at least a portion of the first wing is received within the slot when the first wing is in an insertion position.

9. The medical device assembly according to claim 8, wherein the slot inhibits free rotation of the first wing out of the insertion position.

10. The medical device assembly according to claim 8, wherein an end of the catheter hub is received within the slot.

11. The medical device assembly according to claim 1, wherein at least one of the first wing and the second wing includes a protrusion.

12. The medical device assembly according to claim 11, wherein the housing includes at least one detent configured to engage with the protrusion.

13. The medical device assembly according to claim 1, wherein a radially outer portion of the first wing is releasably attached to a radially outer portion of the second wing in an insertion position.

14. The medical device assembly according to claim 13, wherein the radially outer portions of the first wing and the second wing are designed to be detached following insertion of the catheter into a patient and rotated away from one another toward the patient.

15. The medical device assembly according to claim 14, further comprising an adhesive layer disposed on each of the first wing and the second wing, the adhesive layer designed to adhere to the patient.
