Abstract

A securement device includes a base; a base mount fixedly attached to the base and including a coupling member and a retaining member spaced apart from the coupling member; and a swing arm including an elongate member pivotally coupled to the coupling member and a cannula securement member connected to the elongate member and spaced apart from the coupling member. The cannula securement member is configured to removably secure the cannula thereto and to be detachably coupled to the retaining member. The securement device includes a maintenance state in which the cannula securement member is detached from the retaining member and the swing arm is pivoted away from the retaining member, such that the cannula securement member is spaced apart from the retaining member while being secured to the cannula.

First claim

1 . A securement device for a catheter having a cannula configured to be inserted into a skin of a patient at an insertion site, the securement device comprising:
a base configured to be detachably secured to the skin of the patient; a base mount fixedly attached to the base, the base mount comprising a coupling member and a retaining member spaced apart from the coupling member; and a swing arm comprising:
an elongate member pivotally coupled to the coupling member of the base mount; and
a cannula securement member connected to the elongate member and spaced apart from the coupling member, wherein the cannula securement member is configured to removably secure the cannula thereto, and wherein the cannula securement member is further configured to be detachably coupled to the retaining member;
wherein, upon detachment of the cannula securement member from the retaining member, the swing arm is pivotable relative to the base mount; wherein, in a secured state of the securement device, the cannula is removably secured to the cannula securement member and the cannula securement member is detachably coupled to the retaining member; and wherein, in a maintenance state of the securement device, the cannula securement member is detached from the retaining member and the swing arm is pivoted away from the retaining member, such that the cannula securement member is spaced apart from the retaining member while being secured to the cannula.

2 . The securement device of claim 1 , wherein the base comprises:
a substrate comprising a first major surface fixedly attached to the coupling member and the retaining member, and a second major surface opposite to the first major surface; an adhesive layer at least partially disposed on the second major surface and configured to detachably secure the substrate to the skin of the patient.

3 . The securement device of claim 2 , wherein the adhesive layer comprises a stretch-release adhesive.

4 . The securement device of claim 2 , wherein the substrate comprises:
a first substrate portion fixedly attached to the coupling member; and a second substrate portion fixedly attached to the retaining member; wherein the second substrate portion is disconnected from the first substrate portion, and wherein the adhesive layer is at least partially disposed on the second major surface of each of the first substrate portion and the second substrate portion.

5 . The securement device of claim 1 , wherein the base mount further comprises a connecting member that connects the coupling member and the retaining member.

6 . The securement device of claim 1 , wherein the cannula securement member comprises:
a cannula receiving portion connected to the elongate member and comprising a first slot configured to at least partially receive the cannula therein; and a cap configured to be detachably coupled to the cannula receiving portion and comprising a second slot, wherein, upon detachable coupling of the cap to the cannula receiving portion, the second slot is at least partially aligned with the first slot.

7 . The securement device of claim 6 , wherein, upon insertion of the cannula in the first slot and detachable coupling of the cap to the cannula receiving portion, the first and second slots collectively and at least partially receive the cannula therebetween, such that the cannula is removably secured to the cannula securement member.

8 . The securement device of claim 6 , wherein the cannula securement member further comprises a first sleeve at least partially received within the first slot and a second sleeve at least partially received within the second slot, wherein, upon insertion of the cannula in the first slot and detachable coupling of the cap to the cannula receiving portion, each of the first sleeve and the second sleeve frictionally engages with the cannula, such that the cannula is removably secured to the cannula securement member.

9 . The securement device of claim 6 , wherein the cap is pivotally coupled to the cannula receiving portion or tethered to the cannula receiving portion.

10 . The securement device of claim 6 , wherein the cannula receiving portion of the swing arm detachably couples to the retaining member by a snap-fit connection.

11 . The securement device of claim 1 , wherein the cannula securement member further comprises a release member extending from the cannula receiving portion, and wherein the release member is configured to be manually gripped for releasing the cannula receiving portion from the retaining member.

12 . The securement device of claim 1 , wherein the elongate member comprises a first end and a second end opposite to the first end, wherein the elongate member is pivotally coupled to the coupling member proximal to the first end, and wherein the cannula securement member is connected to the elongate member proximal to the second end.

13 . The securement device of claim 12 , wherein the elongate member further comprises a tapered portion extending from the first end and a curved portion disposed adjacent to the tapered portion, wherein the tapered portion tapers from the curved portion towards the first end, and wherein the curved portion curves away from the cannula securement member.

14 . The securement device of claim 1 , wherein the swing arm is a single integral molded part.

15 . The securement device of claim 1 , wherein the base mount further comprises one or more indicia disposed on the coupling member, and wherein, upon detachable securement of the base to the skin of the patient, the one or more indicia are aligned with the insertion site.

16 . The securement device of claim 1 , wherein the swing arm is pivotable about a pivot axis, and wherein, upon detachable securement of the base to the skin of the patient, the pivot axis intersects the insertion site.

17 . A kit comprising:
a catheter comprising a cannula configured to be inserted into a skin of a patient at an insertion site; and a securement device comprising:
a base configured to be detachably secured to the skin of the patient;
a base mount fixedly attached to the base, the base mount comprising a coupling member and a retaining member spaced apart from the coupling member; and
a swing arm comprising:
an elongate member pivotally coupled to the coupling member of the base mount; and
a cannula securement member connected to the elongate member and spaced apart from the coupling member, wherein the cannula securement member is configured to removably secure the cannula thereto, and wherein the cannula securement member is further configured to be detachably coupled to the retaining member;

wherein, upon detachment of the cannula securement member from the retaining member, the swing arm is pivotable relative to the base mount; wherein, in a secured state of the securement device, the cannula is removably secured to the cannula securement member and the cannula securement member is detachably coupled to the retaining member; and wherein, in a maintenance state of the securement device, the cannula securement member is detached from the retaining member and the swing arm is pivoted away from the retaining member, such that the cannula securement member is spaced apart from the retaining member while being secured to the cannula.

18 . The kit of claim 17 , wherein the base comprises:
a substrate comprising a first major surface fixedly attached to the coupling member and the retaining member, and a second major surface opposite to the first major surface; an adhesive layer at least p
