Abstract
Medical devices used to transfer fluid are disclosed. More specifically, the present disclosure relates to a locking luer adaptor used to connect medical tubing and various medical catheters, such as a pigtail drainage catheter, to another medical tubing, device, or appliance (such as a drainage system that includes a drainage reservoir or receptacle). The locking luer adaptor may be configured to include a locking spin nut and shroud.

A fluid connector, comprising:
- a proximal body;
- a tapered protrusion coupled to and extending distally from the proximal body, wherein a lumen extends through the proximal body and the tapered protrusion;
- a spin nut rotatably disposed over at least a portion of the tapered protrusion;
- and
- a spin nut shroud disposed over the spin nut;
- wherein the spin nut shroud is configured to engage with the spin nut when rotated in a first direction and to disengage from the spin nut when rotated in a second direction.
