Definitions

  • the invention relates to an external programming device for an implant such as a pacemaker, defibrillator or the like with a transmitting and receiving unit for receiving data from the implant and sending data to the implant, and with a display with a display control unit which is used to display representations and / or received data are formed and connected to the transmitting and receiving unit and to a power supply unit.
  • the invention relates to a handheld device for such a programming device and a basic device.
  • Programming devices are generally known and are used for the telemetric programming of implants such as pacemakers or defibrillators.
  • a programming head is usually placed on the skin of a patient, so that the telemetric connection to the implant is made through the patient's tissue.
  • the telemetric connection is preferably bidirectional, so that data from the implant, such as data representing an intracardial electrocardiogram, can also be read out from the implant.
  • the known programming devices do not satisfactorily meet these requirements, so that the object of the present invention is to create a programming device which provides the doctor with as many options and functions as possible in an ergonomic manner.
  • a programming device of the type mentioned at the outset which is constructed in a modular manner from at least one self-sufficient hand-held device and at least one basic device such that the hand-held device comprises the transmitting and receiving unit as well as the display and control unit, and a network-independent, rechargeable power supply and a power supply interface and a data interface.
  • the base device comprises a second power supply interface that is compatible with the power supply interface of the handheld device and a second data interface that is compatible with the data interface of the handheld device.

  • the main advantage of such a modular programming device is that the hand-held device can be designed as a handy, small unit that is easily portable by a doctor, which enables autonomous operation and at the same time makes all essential functions available to the doctor. Because this handheld device can be coupled to the base device, functions that are less frequently required, such as, for example, a printer function or Similar things are provided in the base device and therefore do not burden the handheld device. These functions are available immediately when the handheld device is connected to the basic device. On this occasion, the handheld device is advantageously automatically loaded by the base device.
  • the hand-held device has a data memory, which is connected on the one hand to the transmitting and receiving unit and is designed for the autonomous storage of data sent from the implant or to the implant, and on the other hand is to be connected to the data interface of the hand-held device in such a way that Data is to be transferred at least unidirectionally from the data memory via the data interfaces to the base device when the hand-held device is coupled to the base device.
  • This variant of a handheld device with data memory which serves as an intermediate store for data that is to be printed out via the basic device, in particular when the handheld device is decoupled from the basic device, makes it possible to carry out autonomous operation with the handheld device and later after connecting the handheld device the base unit to print out the data of interest via the base unit.
  • a programming device of the latter type is particularly preferred, in which the basic device has a printer interface or a printer for printing out representations corresponding to the data in the data memory of the hand-held device.
  • the hand-held device is preferably provided with a control unit which is connected and designed to independently detect a coupled state of the hand-held device and to produce a connection between the transmitting and receiving unit of the hand-held device and the printer interface of the base device in response to the detection of the coupled state that data received by the transmitter and receiver unit on the part of the implant can be displayed in real time via the printer or the printer interface.
  • the particular advantage of the last-mentioned embodiment variant is that the hand-held device, when coupled to the base device, can be used in such a way that all of the transmitting and receiving unit of the hand-held device received data can be printed out directly on the printer of the basic device, i.e. in real time.
  • the handheld device and the base device of the programming device preferably each have a data transmission and reception unit for wireless data exchange between the handheld device and the base device.
  • the advantage of data transmission and reception units on the side of the hand-held device and on the part of the base device is that the data interface between the hand-held device and the base device can work wirelessly, so that the hand-held device can be easily carried by the base device even when disconnected and, for example, a real-time printout of data accumulating in the handheld device is possible via the printer of the basic device.
  • the solution to the above-mentioned object also consists in a hand-held device for a programming device of the aforementioned type, in which the display is formed by a touch-sensitive screen (touch screen).
  • a touch screen is particularly advantageous in connection with the hand-held device because areas of the screen that are to be programmed as touch-sensitive buttons on the touch screen, which may differ depending on the operating mode of the hand-held device. This eliminates the need to constantly provide all the necessary switches next to the screen.
  • the hand-held device is preferably designed to establish a latching mechanical connection with the base device, a release button being provided on the hand-held device for releasing the latching mechanical connection.
  • a latching mechanical connection between the handheld device and the basic device enables the handheld device to be securely attached to the basic device.
  • the hand-held device preferably has a shock release button which is connected to a control unit of the hand-held device and the transmitting and receiving unit and cooperates in such a way that the release of a shock by the implant can be triggered via the release button.
  • a defibrillation shock of the implant can be triggered remotely with the handheld device if this display of the intracardiac electrocardiogram on the handheld device indicates, for example, fibrillation of the patient's heart.
  • a hand-held device is preferred which has a programming head which is detachably connected to the hand-held device via a flexible electrical feed line and which is part of the transmitting and receiving unit of the hand-held device. In this way, a telemetric connection between the implant and the handheld device is made possible above the programming head by placing the programming head on the patient's body.
  • the solution to the problem mentioned above also consists in a basic device for a programming device of the aforementioned type, which has a base body and a rocker pivotally articulated to the base body for receiving the handheld device and for tilting the display of the handheld device when the handheld device is coupled.
