Description

BRIEF DESCRIPTION OF THE DRAWINGS

The invention and further advantageous embodiments according to the features of the subclaims are described in more detail below with reference to schematically illustrated exemplary embodiments in the drawing, without herewith restricting the invention to these exemplary embodiments, in which:

FIG. 1 shows an overall medical system according to the invention having a medical injection system and an x-ray diagnosis device

FIG. 2 shows a detailed view of the medical injection system for an overall medical system according to the invention.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 shows an overall medical system 20 according to the invention, which comprises a medical examination or treatment facility 3, a control facility 2 and an assignable medical injection system 1 as essential components. The control facility 2 serves to control and monitor the overall system 20 and to this end features a control computer 7 having a display and an image system 14 for image processing purposes. The control facility 2 is connected to the medical examination or treatment facility 3 by means of a cable, but can however be connected in a cable-free manner or integrated into the medical examination or treatment facility 3.

In accordance with the invention, the control facility 2 can be coupled to the medical injection system 1 by means of a wireless bidirectional communication and/or control link. To this end, the medical injection system 1 has a first transmit and receive means 5 and the control facility has a second transmit and receive means 6. Depending on the wireless communication method, the transmit and receive means 5; 6 can be configured for instance as a radio transmitter/receiver or as an infrared interface.

According to one embodiment of the invention, the communication and/or control between the injection system 1 and the control facility 2 exhibits a complex data protocol based on the CANOpen (Controller Area Network Open) standard for injectors. The standard “CiA DSP 425 (CANOpen in Automation Draft Standard Proposal) Part 2: Injector” is known here for instance. Provision can also be made for the communication and/or control between the injection system 1 and the control facility 2 to comprise a bidirectional transmission of trigger signals. Further possibilities are transmissions by WLAN or Bluetooth.

For fault-free assignment and coupling to the overall system 20, the medical injection system 1 can additionally comprise an RFID transponder (Radio Frequency Identification) 18. Information relating to the injector is stored on the RFID transponder 18. The control facility 2 also additionally features an RFID transmit/receive unit 19. With the assignment of the medical injection system 1 to the overall system 20, the control facility 2 checks by means of the RFID transmit/receive unit 19 whether the suitable injection system 1 is also available in order to avoid potential serious errors as a result of incorrect contrast medium administration.

For examination purposes, a contrast medium 12 is administered to the patient 4 via a supply line 9 and an infusion needle (not shown) by means of the medical injection system. The trigger command of the injection and/or other relevant parameters of the examination are transmitted in a cable-free manner to the medical injection system 1 by means of the control facility 2. The medical injection system 1 likewise transmits its data, such as for instance trigger time or injection quantity, to the control facility 2 in a cable-free manner. The control facility 2 subsequently controls the synchronization with the examination or treatment facility 3 as a function for instance of the injection time.

By way of example, FIG. 2 shows a detailed medical injection system 1. The medical injection system 1 comprises an injector 8 and a control device 10. The control device 10 in turn features the first transmit and receive means 5, a display 15 and an input unit, in particular a 16. The injector 8 includes a piston 11, a cylinder 13 and a contrast medium 12. The contrast medium 12 is injected intravenously into the patient 4 via the supply line 9 by inserting the piston 11 into the cylinder 14. The control unit 10 can check the fill level of the contrast medium 12 by way of a sensor 17 for instance.

On example of a medical injection system 1 is an injection pump, in particular the so-called perfusor. Medical injection systems 1 are also known which do not feature any individual control device 10 but are instead controlled and monitored by means of the CANOpen standard by way of the overall medical system 20. Furthermore, medical injectors 1 are also known, which can inject several substances such as saline solution for instance on the one hand and a contrast medium 12 on the other hand (dual head injector).

The invention can be summarized as follows: to ensure a flexible and patient-friendly examination by means of an overall medical system 20 having at least one medical examination or treatment facility, a control facility 2 and having an assigned medical injection system 1, provision is made for the injection system 1 to be able to be coupled to the overall system 20 by means of a wireless bidirectional communication and/or control link.
