Abstract

An IV catheter insertion guide is configured to reduce the pain a patient may experience during catheter insertion. The IV catheter insertion guide may include two platforms that can be positioned on opposing sides of the insertion site. An upstream platform can include an ultrasonic transducer or another type of heating component for increasing the temperature of tissue near the insertion site. This heating of the tissue can cause the targeted vessel to relax and increase its cross-sectional area prior to insertion of the catheter. A downstream platform can also include an ultrasonic transducer for stimulating nerves downstream from the insertion site during the insertion of the catheter. The stimulation of the downstream nerves may reduce the pain signal that is transmitted to the central nervous system in response to the catheter insertion.

Claims16

Dependent claims

An IV catheter insertion guide comprising:

an upstream platform that is configured to be positioned on a patient's skin on an upstream side of a planned insertion site;
and
a downstream platform that is configured to be positioned on the patient's skin on a downstream side of the planned insertion site opposite the upstream platform, the downstream platform including a nerve stimulating component for stimulating nerves downstream from the planned insertion site,
wherein the upstream platform comprises a main body having a top that forms a first angled support surface in a shape of a partial, inverted cone having an apex, wherein the main body of the upstream platform further comprises an inwardly curved front, wherein the apex is positioned at the inwardly curved front, wherein the first angled support surface is configured to support a catheter device at a first angle, wherein the upstream platform further comprises an elevated support structure that forms a second angled support surface that is configured to support a catheter device at a second angle, wherein the elevated support structure is configured to slide from a first position to a second position, wherein the elevated support structure is oriented towards the apex when the elevated support structure is in the first position and the second position.
