Abstract

catheter system configured to receive an extension may include a catheter adapter, a septum, a catheter and an introducer needle. The catheter adapter may include a proximal end, a distal end, and a lumen extending therebetween along a longitudinal axis. The catheter adapter may also include a first slot, a first groove proximate the first slot, a second slot, and a second groove proximate the second slot. The proximal end of the catheter adapter may include a proximal face having a first opening for the first slot, a second opening for the second slot, and a proximal lumen opening disposed in between the first slot and the second slot. The first slot and the second slot may be configured to receive the extension via a snap-fit, and may be substantially parallel to the longitudinal axis when the extension is received. The first groove and the second groove may include an adhesive. The adhesive may be configured to adhere a first cantilever arm and a second cantilever arm of the extension to the catheter adapter. The septum may be disposed within the lumen and configured to receive an insertion feature of the extension. The insertion feature may actuate the septum to open a fluid path between the extension and the lumen and may be aligned with the longitudinal axis. The catheter may extend along the longitudinal axis distally from the distal end of the catheter adapter and may be configured to be inserted into vasculature of a patient. The catheter adapter is configured to be selectively coupled with a distal end of a needle shield. The introducer needle may extend through the proximal lumen opening and the catheter. The needle shield may be coupled to the catheter adapter and the introducer needle may be configured to be retracted proximally into the needle shield. The adhesive in the first and second groove strengthens the connection between the extension and the catheter adapter and also reduces the risk of blood exposure or undesired disconnection of the extension.

Claims (10)

1. A catheter system configured to receive an extension, the catheter system comprising: a catheter adapter comprising a proximal end, a distal end, and a lumen extending therebetween along a longitudinal axis, wherein the catheter adapter further comprises a first slot, a first groove proximate the first slot, a second slot, and a second groove proximate a second slot, wherein the proximal end comprises a proximal face having a first opening for the first slot, a second opening for the second slot, and a proximal lumen opening disposed in between the first slot and the second slot, wherein the first slot and the second slot are configured to receive the extension via a snap-fit, wherein the first slot and the second slot are substantially parallel to the longitudinal axis when the extension is received, wherein the first groove and the second groove comprise an adhesive, wherein the adhesive is configured to adhere a first cantilever arm and a second cantilever arm of the extension to the catheter adapter; a septum disposed within the lumen and configured to receive an insertion feature of the extension, wherein the insertion feature actuates the septum to open a fluid path between the extension and the lumen, wherein the insertion feature is aligned with the longitudinal axis; a catheter extending along the longitudinal axis distally from the distal end of the catheter adapter, wherein the catheter is configured to be inserted into vasculature of a patient, wherein the catheter adapter is configured to be selectively coupled with a distal end of a needle shield; an introducer needle extending through the proximal lumen opening and the catheter; and the needle shield coupled to the catheter adapter, wherein the introducer needle is configured to be retracted proximally into the needle shield.
2. The catheter adapter of claim 1, wherein a body of the catheter adapter at the proximal face has a distance between the first opening and the proximal lumen opening that is uninterrupted, wherein the body of the catheter adapter at the proximal face has another distance between the second opening and the proximal lumen opening that is uninterrupted.
3. The catheter system of claim 1 or claim 2, wherein the catheter adapter comprises a MARKED-UP stabilization platform.
4. The catheter system of claim 3, wherein the first slot and the second slot are disposed within the stabilization platform.
5. The catheter system of any one of the preceding claims , wherein the proximal lumen opening is configured to receive the insertion feature of the extension, wherein the insertion feature is spaced apart from the first cantilever arm and the second cantilever arm by a plurality of separator elements that extend outwardly with respect to the longitudinal axis.
6. The catheter system of claim 3, wherein an upper surface of the stabilization platform comprises a push tab.
7. The catheter system of claim 6, wherein the push tab is integrally molded from a same material as the stabilization platform.
8. The catheter system of claim 3, wherein the stabilization platform comprises one or more wings that extend outwardly from the longitudinal axis.
9. The catheter system of claim 3, wherein the stabilization platform is formed of one or more of a soft plastic or an elastomer such as silicone rubber.
10. The catheter system of claim 3, wherein a distal end of the stabilization platform includes a gradual taper. lili!
