Embodiment Construction

[0054] Devices of the present invention for topical application include thermal patches. This thermal patch is activated by applying pressure. At this point, it can be bent or pressed to initiate an exothermic chemical reaction that heats the patch to a temperature of 50 to 55 degrees Celsius.

[0055] In one embodiment of the invention, the exothermic chemical reaction heats the patch to a temperature of 50 to 54 degrees Celsius, such as 50 to 53 degrees Celsius or 50 to 52 degrees Celsius. In one embodiment of the invention, the exothermic chemical reaction heats the patch to a temperature of 51 to 55 degrees Celsius, such as 51 to 54 degrees Celsius or 51 to 53 degrees Celsius. In one embodiment of the invention, the exothermic chemical reaction heats the patch to a temperature of 50 to 54 degrees Celsius, such as 51 to 54 degrees Celsius or 52 to 54 degrees Celsius.

[0056] Preferably an exothermic chemical reaction heats the patch to a temperature of 50 to 55 degrees C...

Abstract

The present invention provides a device for application to the skin of a patient to facilitate intravenous access, for example via a needle, syringe, cannula or catheter, the device having an upper surface and a lower surface, wherein the lower surface is adapted to be Contact the patient's skin at the site of the vein. The device includes a thermal patch, an organic nitrate vasodilator, and an amino-based anesthetic that is an amino ester or amino amide. The device is configured and arranged such that, in use, the device can be activated by applying pressure to the patch to initiate an exothermic chemical reaction in the thermal patch which heats the patch to 50 to a temperature of 55 degrees Celsius for one minute or longer. Furthermore, the device is configured and arranged such that when the device is applied to the patient's skin, its lower surface contacts the patient's skin, and the vasodilator and anesthetic are released from the underside of the device onto the patient's skin at the location where the vein is to be accessed .

Description

technical field [0001] The present invention relates to devices for application to the skin of a patient to facilitate venous access. Background technique [0002] Obtaining intravenous access, whether via cannulation (for administering intravenous fluids, medications, or blood transfusions) or venipuncture (for sampling blood for laboratory testing purposes), is the most commonly performed medical procedure. Insertion of an IV access device (cannula or needle) into a human vein by a clinician is performed for patients accessing hospital services, both at the time of visit and at frequent intervals during admission. [0003] A cannula is a device used to gain peripheral venous access for intravenous therapy administration. Cannulas are commonly used to access peripheral veins in a patient's hand, foot, inner elbow, or forearm. [0004] The cannula remains in place as long as the healing process is required. The cannula consists of a needle surrounded by a plastic sheath. ...
