SPHYGMOMANOMETER

摘要

The data transmission device (8) comprises a separate interchangeable interface transducer detachably connected to a device body of the sphygmomanometer and to a connection interface of the measuring device by an internal connection interface (9). The data and/or transmission format is adapted to the measuring device and another data and/or transmission format is adapted to the respective external data processing device and/or vice-versa. The connection interface of the measuring unit is resistor serial port (RS-232-port) and exhibits a chip card-contacting unit (12). The interface transducer has a protocol converter at the internal connection interface intended data transmission protocol and at the external transmission interface intended data transmission protocol and/or in reverse synchronization and has a level transducer at the internal connection interface intended data signal level and at the external transmission interface (10) intended data signal level. The external transmission interface of the interface transducer is instructed as infrared interface, fax modem, chip card terminals, cable connection interface, Bluetooth (RTM) unit, universal serial bus (USB) interface, as firewire port and/or as wireless local area network (WLAN) interface. The data transmission device comprises a charging circuit for electrical charge of a rechargeable battery arranged in device body of the sphygmomanometer and forms a plug connection with device body of the sphygmomanometer. The data transmission device and the connection interface are bi-directional units. An independent claim is included for data transmission unit for blood pressure measuring apparatus.
