Abstract

A medical article is configured to provide access to a patient'"'"'s vasculature. The medical article includes an elongated body and a pair of stabilizing wings that extend from the elongated body and are configured to stabilize the medical article on a patient. The stabilizing wings are configured to rotate together or independently about the longitudinal axis of the elongated body between at least a first configuration and a second configuration. The elongated body can include a one-way valve disposed therein. The medical article can also one or more adhesive layers configured to releasably attach at least a portion of the wings to a patient.

Claims

1. A medical article for use in providing access to a patient'"'"'s vasculature, the medical article comprising:

a catheter hub having a longitudinal axis, a distal end, and a proximal end;

a catheter continuously extending from the proximal end of the catheter hub, the catheter and the catheter hub together defining a continuous lumen;

a housing surrounding the catheter hub, wherein a channel is defined between the housing and the catheter hub;

the channel surrounding the catheter hub; and

a pair of wings extending away from the catheter hub, at least a first wing of the pair of wings being configured to rotate about the longitudinal axis of the catheter hub between at least a first configuration and a second configuration, the first wing including a hook portion coupling the first wing to the housing, wherein at least a portion of the hook portion is disposed within the channel.

2. The medical article of claim 1, wherein the catheter includes a bevel disposed near a distal end of the catheter, the bevel and at least a portion of the first wing being rotationally aligned about the longitudinal axis of the catheter hub when the first wing is in the first configuration.

3. The medical article of claim 1, further comprising an adhesive layer disposed on at least a portion of one side of each wing of the pair of wings, the adhesive layer configured to releasably attach each wing of the pair of wings to a patient'"'"'s skin.

4. The medical article of claim 1, wherein the catheter hub comprises a luer connector disposed near the distal end, the luer connector being configured to connect the catheter hub with a medical line.

5. The medical article of claim 1, wherein each wing of the pair of wings is configured to rotate independently from one another.

6. The medical article of claim 1, wherein rotation of one wing of the pair of wings rotates the other wing of the pair of wings.

7. The medical article of claim 1, wherein each wing of the pair of wings is spring-loaded and configured to be biased to rotate away from one another from the first configuration to the second configuration.

8. The medical article of claim 1, wherein at least one wing of the pair of wings includes a protrusion.

9. The medical article of claim 8, wherein the housing includes at least one detent configured to engage with the protrusion.

10. The medical article of 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 the first configuration.

11. The medical article of claim 10, wherein the slot inhibits free rotation of the first wing from the first configuration towards the second configuration.

12. The medical article of claim 10, wherein a proximal end of the catheter hub is received within the slot.

13. A medical article for use in providing access to a patient'"'"'s vasculature, the medical article comprising:

a catheter hub having a longitudinal axis and a distal end;

a catheter continuously extending from a proximal end of the catheter hub, the catheter and the catheter hub together defining a continuous lumen;

a housing surrounding the catheter hub, wherein a channel is defined between the housing and the catheter hub;

the channel surrounding the catheter hub and a pair of wings extending from the catheter hub, wherein the wings are releasably attachable to one another and configured to independently rotate about the longitudinal axis of the catheter hub between at least a first configuration and a second configuration upon detachment of the wings from one another, wherein a first wing of the pair of wings includes a hook portion coupling the first wing to the housing, wherein at least a portion of the hook portion is disposed within the channel.

14. The medical article of claim 13, further comprising an adhesive layer disposed on at least a portion of one side of each wing of the pair of wings, the adhesive layer configured to releasably attach each wing of the pair of wings to a patient'"'"'s skin.

15. The medical article of claim 13, wherein the catheter hub comprises a luer connector disposed near the distal end, the luer connector being configured to connect the catheter hub with a medical line.

16. A method, comprising:

providing a handpiece including a slot, a first contoured surface and a second contoured surface, the first contoured surface and the second contoured surface forming a concave shape;

providing a medical article, comprising;

an elongated body having a longitudinal axis, a distal end, and a proximal end, a pair of wings extending from the elongated body, each wing having a portion adjacent the elongated body coupled thereto, the coupled portion of each wing of the pair of wings moving with respect to the elongated body from a first configuration to a second configuration, wherein the coupled portions are adjacent to one another in the second configuration, a housing surrounding the elongated body, wherein a channel is defined between the housing and the elongated body, the channel surrounding the catheter hub and a catheter extending from the proximal end of the elongated body in a direction substantially parallel to the longitudinal axis of the elongated body; and

positioning at least a section of each wing of the pair of wings within the slot of the handpiece to inhibit free rotation of the pair of wings from the first configuration towards the second configuration and a hook portion coupling the first wing to the housing, wherein at least a portion of the hook portion is disposed within the channel.

17. The method of claim 16, further comprising removing the section of each wing of the pair of wings from the slot.

18. The method of claim 16, further comprising securing each wing of the pair of wings relative to a patient.

19. The method of claim 16, further comprising rotating each wing of the pair of wings from the first configuration to the second configuration.
