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.
