Abstract: A biological energy signal acquisition and conversion device comprises: a signal acquisition module, enhancing a biological energy signal generated by an original biological energy body, and extracting the signal; a signal processing module, receiving the extracted original biological energy signal and filtering and amplifying the signal, and generating an output energy signal; and a signal output unit, being able to enhance an output function in cooperation with a magnetic substance, and output the energy signal to a biological energy carrier. By shortening the distance between the original biological energy body and a signal receiving unit, and using the magnetic substance to excite the original biological energy body, the strength of the received extracted original biological energy signal is enhanced, and the noise proportion is greatly reduced, reducing the technical complexity and costs for back-end signal processing, and improving the effect of a biological energy signal.

Abstract: Apparatus for intravascular access device displacement detection, where an intravascular access device is inserted into a blood vessel through the skin at an access site. The apparatus comprises electrodes located on either side of the intravascular access device which electrodes are mobile with the intravascular access device and attachable to the skin about the access site. The electrodes have a micro-current flow therebetween, which is sufficient to induce a current through the skin between the electrodes and the current persists as long as the electrodes are connected. If the device moves then one or more of the electrodes are disconnected and the micro-current is interrupted. A displacement alert device issues an alert signal upon interruption of the micro-current.
