- the user can then connect the catheter connector 10 to a fluid delivery device (e.g. a syringe) such that fluid is injected into the cavity 13 of the proximal end port 14.
- the fluid pressure from injection causes the seal 15 to deform around the catheter 1 1 , thereby sealing the proximal end of the catheter 11 within the catheter connector 10.
- the combination of the plate 38 locking the catheter 11 and the seal 15 deforming around and sealing the catheter 1 1 temporarily secures the catheter 1 1 within the catheter connector 10 such that the user can administer fluids to the patient quickly and effectively, while the needle is still in the patient, if needed.
- a user may remove the needle from the patient and over the catheter 1 1 , The user can then either use a hub of the needle or one or more of his fingers to assist in pushing the push component 8 to the open position. As such, the plurality of spokes 38 of the plate 36 are displaced towards the proximal end 23 of the body 12, thereby releasing the catheter 11 from the connector 10. The user is then capable of removing the needle from the catheter 1 1. After removal of the needle, the user can reconnect the catheter 1 1 and the connector 10 in a permanent manner.
- the user again pushes the push component 18 to the open position and inserts the catheter 1 1 until it again reaches a hard stop, typically corresponding to recess 21 .
- the user can then optionally move the push component 18 to the locked position.
- the user tightens or screws the proximal end port 14 into the proximal end 23 of the body 12 of the catheter connector 10 so as to compress the seal 5.
- the connector 10 may include a visual Indicator signaling to the user when to stop tightening the proximal end port 14, In another embodiment, the user may tighten the proximal end port 14 until he cannot tighten further.
- the proximal end port 14 compresses the seal 15 around the catheter 1 1 , which creates a more secure connection than the fluid pressure and plate configuration described above in regards to the temporary securement
- the user can simply unscrew or loosen the proximal end port 14 such that the seal 15 is no longer compressed. As such, the catheter 1 1 can be easily removed.
- temporary securement of the catheter 1 1 may not be needed, in which case the user can simply neglect the steps above in regards to temporary use.
- the user first inserts the distal end of the needle and catheter assembly into the patient. The user then removes the needle from the patient and over the catheter. The user then inserts the catheter 1 1 into the interior 31 of the body 12 and at least partially within the seal 15. The user may then tighten or screw the proximal end port 14 into the proximal end 23 of the body 12 of the catheter connector 10 so as to compress the seal 15 around the catheter 1 1 .
- this embodiment may or may not include the push component 18 and plate 36 configuration as described herein., for example, as shown in FIG. 1 .
- the catheter connection may be a part of a larger connector assembly 100 for use with a catheter 102.
- the connector assembly 100 includes a catheter 102 having a proximal end (secured within the catheter connector 1 10), a distal end (not shown), and walls 104 defining a lumen 106.
- the catheter connector 1 10 includes a body 1 12 having a proximal end 123 and distal end 125.
- the proximal end 123 includes a proximal end port 14 configured thereon for mating communication with a fluid delivery device (not shown).
- the catheter connector 1 10 may include any of the features described herein.
- the catheter connector 100 may further include a seal configured within the body 1 12 (not shown), a push component 118 configured to move between an open position and a iocked position, a housing 128, and a plate (not shown).
- the connector assembly 100 may include a securement device 154 for securing the catheter 102 and the catheter connector 110 relative to a patient
- the securement device 154 may be any suitable device known in the art.
- the securement device 154 may include a base 155 configured to attach to a patient or other suitable surface.
- the securement device 154 may include one or more grooves for securing the flanges 144. Further, the securement device 154 may include the "Grip-LokTM” securement device from Zefon International Inc. of Gcala, FL, USA. This device includes an adhesive base layer that attaches to the patient's skin.
