Ultra low-leakage silicone-based heater thermally coupled to a heat transfer body

Systems and methods include a heat transfer body with opposing major surfaces formed from a thermally conductive substrate in intimate thermal interaction with an alumina exterior surface that extends across the major surfaces of the body. In an illustrative example, the heat source may be a substantially planar, silicone-based heater source (P-SBHS). The heat transfer body may be configured to thermally interact, for example, heat from a heat source proximate a first of the major surfaces to a second of the major surfaces. A temperature sensor module may be located, for example, proximate to the first major surface such that a temperature sensor thermally interacts with the first major surface. The temperature sensor module may, for example, insulate the temperature sensor from the P-SBHS.

Catheter insertion systems

Disclosed catheter insertion systems enable the user to identify the location of the needle based on the electrical properties of subcutaneous tissue relative the electrical properties of other fluids such as blood or air. Disclosed systems can include one or more of the following features: 1) the catheter assembly is modular (e.g., the catheter can be connected and disconnected from the detection unit at will); 2) the detection unit employs an electrical circuit that allows for the discernment between subcutaneous tissue and blood; 3) the system assists the end user with catheter advancement. Some embodiments can be used to insert catheters into a spaces where the needle passes first through subcutaneous fat and muscle before entering fluid or air.
