Catheter housing
A catheter housing device for securing a catheter and needle assembly to a patient. The device can include a cover, an IV/catheter lock, a hub, and one or more fastening straps. The device can replace conventional devices and techniques for securing a catheter and needle to a patient that utilize adhesive materials and/or methods, which are ill-equipped to solve complications including infection/contamination of the insertion site, irritation/damage to the vein or insertion site due to inappropriate angling of the catheter/needle, etc. The devices and methods disclosed herein can provide catheter/needle securement and optimal inclination, a hermetically sealed chamber to resist infection and/or contamination, inert gas or soothing anesthetic vapor drugs in and around the device, and various skin-contacting layers and structures that promote ventilation and patient comfort in and around the insertion site.
1. A catheter housing device configured to be positioned atop a catheter insertion site on a subject, the catheter housing device comprising:
a hub component comprising a membrane configured to secure to skin of the subject around the catheter insertion site when the catheter housing device is in use, wherein the membrane includes an opening configured to be positioned over the catheter insertion site;
a cover configured to secure to the hub component and configured to at least partially enclose the catheter insertion site when the catheter housing device is in use, wherein the cover comprises an interior surface and an exterior surface;
a catheter lock component configured to at least partially retain a catheter hub coupled to a catheter to reduce movement of the catheter when the catheter is inserted into the subject at the catheter insertion site; and
at least one port extending outwardly from a portion of the exterior surface of the cover, wherein the at least one port is configured to allow gas to flow into an interior of the cover.
2. The catheter housing device of claim 1 , wherein the membrane extends around an entirety of a perimeter of the cover when the cover is secured to the hub component.
3. The catheter housing device of claim 1 , wherein the at least one port is configured to secure to a tube to allow gas flowing through the tube to flow into the interior of the cover.
4. The catheter housing device of claim 1 , wherein the at least one port is configured to allow a sterilizing gas to flow into the interior of the cover.
5. The catheter housing device of claim 1 , wherein the at least one port comprises a valve.
6. The catheter housing device of claim 1 , wherein the at least one port comprises an at least partially cylindrical fluid passage.
7. The catheter housing device of claim 1 , wherein a bottom surface of the membrane is configured to secure to the skin of the subject.
8. The catheter housing device of claim 1 , wherein the hub component further comprises a main body connected to the membrane and configured to surround the catheter insertion site when the catheter housing device is in use, and wherein the cover is configured to secure to the main body.
9. The catheter housing device of claim 1 , wherein the cover comprises one or more protrusions, each of the one or more protrusions configured to engage a portion of the hub component and secure the cover and the hub component to each other.
10. The catheter housing device of claim 1 , wherein the catheter lock component and the hub component comprise a unitary structure that is removably securable to the cover.
11. The catheter housing device of claim 1 , wherein the catheter housing device is configured to allow said gas to flow through said at least one port, into said interior, and toward the catheter insertion site when the catheter housing device is in use.
12. A catheter housing device configured to be positioned atop a catheter insertion site on a subject, the catheter housing device comprising:
a hub component comprising a membrane configured to secure to skin of the subject around the catheter insertion site, wherein the membrane includes an opening configured to be positioned over the catheter insertion site when the membrane is secured to the skin around the catheter insertion site;
a cover configured to at least partially enclose the catheter insertion site when the catheter housing device is in use, wherein the cover comprises an interior surface and an exterior surface; and
at least one port extending outwardly from a portion of the exterior surface of the cover, wherein the at least one port is configured to allow gas to flow into an interior of the cover.
13. The catheter housing device of claim 12 , wherein the cover is configured to secure to the hub component, and wherein the membrane extends around an entirety of a perimeter of the cover when the cover is secured to the hub component.
14. The catheter housing device of claim 12 , wherein the at least one port is configured to allow a sterilizing gas to flow into the interior of the cover.
15. The catheter housing device of claim 12 , wherein the at least one port is configured to secure to a tube to allow gas flowing through the tube to flow into the interior of the cover.
16. The catheter housing device of claim 12 , wherein a bottom surface of the membrane is configured to secure to the skin of the subject.
17. The catheter housing device of claim 12 , wherein the cover comprises one or more protrusions, each of the one or more protrusions configured to engage a portion of the hub component and secure the cover and the hub component to each other.
18. The catheter housing device of claim 12 , wherein the catheter housing device is configured to allow said gas to flow through said at least one port, into said interior, and toward the catheter insertion site when the catheter housing device is in use.
19. A catheter housing device configured to be positioned atop a catheter insertion site on a subject, the catheter housing device comprising:
a hub component comprising a membrane configured to secure to skin of the subject around the catheter insertion site, wherein the membrane includes an opening configured to be positioned over the catheter insertion site when the membrane is secured to the skin around the catheter insertion site;
a cover configured to at least partially enclose the catheter insertion site when the catheter housing device is in use, wherein the cover comprises one or more protrusions, each of the one or more protrusions configured to engage a portion of the hub component and secure the cover and the hub component to each other; and
at least one port extending outwardly from a portion of the cover, wherein the at least one port is configured to allow gas to flow into an interior of the cover.
20. A catheter housing device configured to be positioned atop a catheter insertion site on a subject, the catheter housing device comprising:
a hub component comprising a membrane configured to secure to skin of the subject around the catheter insertion site when the catheter housing device is in use, wherein the membrane includes an opening configured to be positioned over the catheter insertion site;
a cover configured to secure to the hub component and configured to at least partially enclose the catheter insertion site when the catheter housing device is in use;
a catheter lock component configured to at least partially retain a catheter hub coupled to a catheter to reduce movement of the catheter when the catheter is inserted into the subject at the catheter insertion site, wherein the catheter lock component and the hub component comprise a unitary structure that is removably securable to the cover; and
at least one port extending outwardly from a portion of the cover, wherein the at least one port is configured to allow gas to flow into an interior of the cover.
