Abstract:
El objeto de esta invención es un dispositivo ortésico portátil que es compacto y no invasivo. El dispositivo ortésico es de utilidad para el amortiguamiento del temblor y comprende: Un sustrato o sistema de soporte para fijar el dispositivo al miembro superior que comprende una part distal y una parte proximal. Al menos un sensor unido al sustrato para medir el movimiento del miembro y generar una señal sensorial. Al menos un actuador anclado a la parte proximal del sustrato capaz de aplicar una fuerza, a través de la parte distal del sustrato, al miembro del usuario para amortiguar su temblor. Un dispositivo de control que incluye un procesador que analiza la señal del sensor para detectar el temblor y generar la señal de control del actuador para amortiguar el temblor.
Abstract:
An implant device for creating a neural interface with the central nervous system having a polyimide-based electrode array is presented along with a method for making the device. The device may be configured as a three dimensional structure and is capable of sensing multi-unit neural activity from the cerebral cortex. Mechanical, electrical and biological characteristics of the device support its use as a reliable, long term implant.
Abstract:
An electrode (10) for establishing electrical connection between a lead wire (12) and a surface includes a contact portion (20) and a conductive bridge portion (22). The contact portion (20) includes a conductive layer (24), an insulator layer (26) on one side thereof, and an anchor or adhesive layer (28) on the other side thereof for anchoring the contact portion (20) to the surface. The bridge portion (22) extends from the contact portion (20) and is electrically connected with the conductive layer (24). The bridge portion (22) includes a receptor (40) to which the lead wire (12) is atachable and a series (32) of perforations (34) which form a breakaway or yieldable connection mechanism for allowing the bridge portion (22) to be partially pulled apart when applied to the surface. The series (32) of perforations (34) thus allow the receptor (40) to move yieldably with six degrees of freedom of movement relative to the contact portion (20) while still maintaining electrical connection with the conductive layer (24).
Abstract:
A thermistor airflow sensor assembly (10) for monitoring the breathing of a patient, comprising thin, flexible, resilient layers of film (12, 14) adhesively secured to form a laminate. Copper conductor strips (32) are formed by etching away a copper layer attached to the lower film prior to lamination, with chip thermistors (30) being soldered to the copper conducting strips. The copper conducting strips extend through an enlarged end portion of the assembly for electrical connection to a cable, a bend relief cable, and a plug which can be connected to a monitor for providing visual and/or audio alarm signals when breathing has been interrupted. A separate carrier strip can be mounted on the film layer adapted to be positioned against the face of the patient, whereby the thin flexible assembly can be easily adapted to the facial configuration of the patient.
