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 invention provides a device for application to the skin of a patient to facilitate intravenous access, e.g. via needles, syringes, cannulas or catheters, the device having an upper surface and a lower surface, wherein the lower surface is suitable for contacting the skin of the patient at the location of a vein to be accessed. The device comprises a heat patch, an organic nitrate vasodilator agent and an amino based anaesthetic agent which is an amino ester or amino amide. The device is configured and arranged such that in use the device can be activated by the application of pressure to the patch so as to initiate an exothermic chemical reaction in the heat patch which heats the patch to a temperature of from 50 to 55 degrees Celsius for a period of time of one minute or more. Further, the device is configured and arranged such that when the device is applied to the skin of the patient, with the lower surface contacting the skin of the patient, the vasodilator agent and the anaesthetic agent are released from the lower side of the device onto the patient's skin at the location of a vein 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. ...
