Topical drug delivery devices and methods of use

Abstract

Devices, groups of devices, kits, and methods for using the devices and kits to administer a local anesthetic to a port site to numb the site prior to infusion or blood draw are described. The devices contain a flexible material with an adhesive coating on one side and a compartment for containing the medication. The device can be pre-filled or a fillable device. In fillable devices, the local anesthetic is transferred from a container into the compartment of the device via the inlet after the device is applied to the patient's skin. In pre-filled devices, the local anesthetic is inside the compartment and is covered with a removable layer to keep it sterile until use. When applied to the patient's skin, the device conforms to the surface of the patient's skin forming a seal keeping the medication in contact with port site.
