LOCATOR SYSTEM FOR ACCESS DOOR WITH RFID LABEL. The invention relates to a fluid access gate locator system implanted for the adjustable gastric bands. The system may include an access port that has an RFID tag with its antenna adjacent to the receiving portion of the port. An external locator with a radio frequency receiver transmitter circuit 1 sends read or interrogation signals to the RFID tag and can send the write signals to the tag to write the treatment data into the RFID tag memory. The locator may include a network of four paired directional amplifier antennas to model two single-pulse radar antenna systems. The locator also includes processor (s) and logic circuitry modules 1 for processing the tag response signals received by the antenna network to determine the location information for the RFID tag and associated port, that is, to identify the center. relative to the antenna network or network face such as the intensity and direction information for the network face. One method for locating an implanted fluid access port includes providing a radio frequency receiver transmitter circuit 1 over the access port and manipulating a portable locator outside the body to locate the position and orientation of the access port. A mark may be made with a portable locator to direct the insertion of a needle to add or remove fluid from a system implanted through the access port.SISTEMA LOCALIZADOR PARA PORTA DE ACESSO COM ETIQUETA RFID. A invenção refere-se a um sistema localizador de porta de acesso de fluido implantado para as bandas gástricas ajustáveis. O sistema pode incluir uma porta de acesso que tem uma etiqueta RFID com a sua antena adjacente à porção de recebimento da porta. Um localizador externo com um circuito de transmissor 1 receptor de frequência de rádio envia sinais de leitura ou de interrogação para a etiqueta RFID e pode enviar os sinais de escritas para a etiqueta para escrever os dados de tratamento na memória da etiqueta RFID.
