Definitions
- the invention relates to a medical device according to the preamble of claim 1 and a method for programming, performing test sequences, diagnosis and maintenance of such a device.
- Such medical devices often have a computer architecture with two communication buses.
- Such a computer architecture is generally appropriate if a medical device needs an auxiliary computing system in addition to its action computing system due to security needs, which independently monitors the functioning of the action computing system and can bring about a safe state of the device in an emergency.
- the auxiliary computer for operating the hemodialysis machine has an external interface. Via this interface, it is possible to carry out the programming, the execution of test sequences, the diagnosis and the maintenance of all computers of the hemodialysis machine with the help of an external device.
- the computer architecture of this device proves to be disadvantageous from the following point of view. While the auxiliary computers can be addressed relatively easily via the auxiliary bus, the action computers can only be addressed via the module-internal interface between an action computer and the associated auxiliary computer. Only after such a transition can the data be sent via the action bus.
- the internal computer connection proves to be a bottleneck with regard to the data transmission speed, which results in unnecessarily long times in data communication.
- module-internal communication there are also other types of concerns about module-internal communication. If data are to be transmitted to an action computer, it is necessary for the reasons mentioned to use the module-internal interface between an action and the associated auxiliary computer in at least one unit. This means that several computers are always involved in the data transfer process. Additional software is also required in each computer in order to be able to handle the data transfer at all. The process is thus complex and prone to errors.
- DE-A-37 36 712 describes a similar, modular dialysis machine that provides a hierarchical computer structure. All control processors are connected to a main control processor and all monitor processors are connected to a main monitor processor. The main processors are in turn interconnected.
- EP 0 491 183 A1 a device is known in which driver and receiver units are connected between a main data bus and an internal bus. So that the internal bus can also be accessed from the main data bus for test purposes, bidirectional logic means are provided which, however, have a complicated structure.
- EP 0 306 211 A2 describes a very complex, synchronized twin computer system. To coordinate the clock sequences and the programs running in parallel, data communication between two computer systems via dedicated controllers is provided.
- DE 40 22 365 A1 presents a data transmission system in which an address and a data bus between a microprocessor and a data memory can be interrupted for the purpose of more efficient direct memory access (DMA).
- DMA direct memory access
- An external device for the diagnosis of an integrated circuit via a bus system is the subject of GB 2 282 244 A.
- the invention has for its object to develop a generic medical device in such a way that simple, fast and safe programming, sequence of test sequences, diagnosis and / or maintenance of the terminals located on both buses is made possible.
- this object is achieved by a medical device according to the preamble of claim 1 in that a connecting line which can be interrupted by a switch is provided, by means of which the two communication buses can be connected to form a uniform communication bus.
- the two communication buses whenever an external device for programming, for carrying out test sequences, for diagnosis and / or for maintenance System to be connected to create simple, fast and secure connection paths with a connection of the two communication buses to a uniform communication bus, which can be separated again safely and reliably after these procedural steps.
- the switch is expediently designed as a relay switch, but other switches which enable a uniform connection between the two communication buses can also be used.
- the connecting line can be interrupted with two switches arranged in series.
- One switch can be actuated by a computer that is connected to the first communication bus, and the other switch can be operated by a computer that is connected to the second communication bus.
- means for mode determination are provided which always exclude a connection of the communication buses when the medical device performs its actual function in the sense of a medical application, for example during a hemodialysis treatment.
- the device for connecting the two communication buses must expediently be in a specific mode provided for this purpose. This is to ensure that the safety concept of the medical device, which is based, among other things, on the two separate communication buses, cannot be circumvented.
- the means for determining the mode are advantageously part of the programming of the computers involved, which control the switch or switches.
- the medical device can have an interface directly on one of the two communication buses, on one of the computers or - in the case of a connecting line with two switches - in the connecting line between the two switches. In the latter case, there is a particularly reliable process when connecting to an external device, since each computer system that is connected via a communication bus can control whether it wants to be connected to the external device.
- the external device can be implemented by a further computer or a computer network, the connection being able to consist of a local connection or an intranet or internet connection.
- Detector means can be provided which checks the switch status and reports it to one of the computers.
- addressing is advantageously used, which maintains its uniqueness in the case of the bus connection.
- CAN buses are used as communication buses.
- At least two units of the medical device each have an action and an auxiliary computer, the action computers being connected to one another via the first communication bus and the auxiliary computers via the second communication bus.
- the medical device is a blood treatment device.
- a blood treatment device which generally has an extracorporeal blood circuit in which blood is drawn from a patient or a donor, treated and returned, has high safety requirements, and for this reason it also has a complex structure.
- Blood treatment methods include blood purification by dialysis and / or filtration, by adsorption or by centrifugation.
- a basic structure of a medical device to be used for the invention is described in DE 198 49 787 C1.
- an operating unit for data inputs and outputs a hydraulic unit for supplying and removing the dialysis fluid and the ultrafiltrate, and a functional unit for controlling the extracorporeal blood circulation are provided.
- Each unit has an action and an auxiliary computer, the action computers being connected to one another via a first bus and the auxiliary computers via a second bus.
- such a dialysis machine can also be provided for hemofiltration, in which the hydraulic unit takes over the provision of substitution fluid instead of providing the dialysis fluid.
- substitution fluid instead of providing the dialysis fluid.
- the invention is also based on the object of providing a method for a simple, fast and safe programming, test, diagnosis and / or maintenance process of a generic medical device with an interface to an external device.
- the object is achieved in that for this purpose an external device is connected to the interface provided, the two communication buses are connected to form a uniform communication bus, the programming, test, diagnosis and / or maintenance process is carried out by the external device , and after the completion of the programming, test, diagnosis and / or maintenance process, the communication buses are separated again.
