Description

The present invention relates to a system for monitoring a conduit system for medical fluids, in particular a conduit system for the application of medical fluids for a patient.

Application systems for medical fluids for patients, in particular intensive care patients, are already known from the prior art. For this purpose, in particular syringe pumps are used, by means of which drugs can be administered to a patient, for example via an intravenous access.

From the prior art is already out of the EP 0 158 683 A1 a device for the intermittent application of liquid medicines, comprising a replaceable storage container for the drug, a flexible hose attached thereto, a catheter connectable to the outer end of the tube, a roller pump acting on the tube and a drive motor for the roller pump, and a delivery pulse timer - And pauses of the roller pump has. Also provided is a display for interference situations, wherein a microcomputer is further provided, by means of which a control of the system is possible.

From the WO 2008/145256 A2 A method and apparatus for checking the correct coupling of an adding device to a therapy device having an extracorporeal circuit is known. In this case, the adding device is connected to the extracorporeal circuit in such a way that by means of the adding device during operation of the therapy device, a means in the extracorporeal circuit can be inserted, wherein the adding device is coupled on the suction side of a arranged in the extracorporeal circuit pump to the extracorporeal circuit. Further, there is a portion in the negative pressure area of the extracorporeal circuit in connection with a portion of the adding device opposite to the other parts of the extracorporeal circuit, and the pressure in that sealed portion is changed and measured. As a result, the correct coupling of the adding device to the therapy device is checked.

From the prior art syringe pumps for metered delivery of liquids are known, for example from the EP 0 369 322 A2 or the DE 298 12 065 U1 ,

In connection with the treatment, especially of intensive care patients, it behaves in such a way that a variety of drugs is administered, whereby in addition to a correct dosage and any contraindications and intolerances of the drugs must be taken together. In addition, care must also be taken to ensure that the existing lines are correctly connected and switched through according to the treatment plan.

It is the object of the present invention to further develop a system for monitoring a line system for medical fluids of the type mentioned in an advantageous manner, in particular to the effect that this is an easy-to-implement yet reliable verification of the application and supply of medical fluids, in particular medicines a patient.

This object is achieved by a system for monitoring a conduit system for medical fluids with the features of claim 1.

Thereafter, it is contemplated that a system for monitoring a medical fluid conduit system includes at least one medical pumping device having a pump control device and at least one control record, at least one medical fluid line, at least one medical access to a patient to be treated, at least one connection and / or or tap, which is connected to the line system in operation, and at least one monitoring unit, wherein the monitoring unit is connected to the pump control device in operation and has access to the control data record, and wherein by means of the monitoring unit, the line system and the connection of at least one connection and / or connecting tap with the line system visually and / or electronically verifiable.

The invention is based on the idea that an automated medical medication device consisting of a medical pump device, such as a syringe pump (or even several syringe pumps, such as the perfusors of B. Braun), the corresponding lines, the connection taps and also the connection of the line to the medical access, such as an intravenous access or catheter to be checked by a monitoring unit. By means of the monitoring unit, it is possible to check whether the planned medication was actually administered to the patient and that in particular the corresponding parameters such as dosage, quantity, volume flow, correct line connection or line release also corresponds to the actually planned treatment. So is For example, it is known that completely or only partially closed connection and / or connection faucets, such as, for example, 3-way faucets, can already lead to the actually planned medication not reaching the patient. Due to the sometimes very low volume flows, by means of which the medication is administered to patients, it has already happened that a medication that does not take place because of closed lines or not late, because due to the flow rates it does not lead to a significant increase in pressure and / or Backwater in the piping system comes.

Furthermore, it can be provided that the monitoring unit adjusts the control data record with the state of the connection. This advantageously makes it possible to check the planned control data of the pump device against the actual situation of the connection of connection and / or connection tap with the line system. Thus, for example, it can be checked whether a planned delivery by means of the pump device can actually reach the patient, since there must be an open and correct connection for this purpose.

In addition, it is possible that the conduit system has at least one optical and / or electronic identification that identifies the transported medical fluid, wherein the identification can be read out by the monitoring unit. It is conceivable in this context that, for example, a line of the conduit system is used only for a predetermined drug and a corresponding identification of this line also takes place. Such identification may be accomplished, for example, by the use of optical codes that are machine readable, such as bar codes or QR codes, or the like.

It is also conceivable, however, to use electronically readable codes, such as RFID codes, which can be read out, for example, wirelessly.

In this context, it is also conceivable that the markings are also color appropriately deposited and that the corresponding lines of the line system are also provided with a sticker that identifies the drug used and transported in the line drug with all necessary information important for the treatment.

Furthermore, it can be provided that the monitoring unit has a database in which compatibilities of medical fluids are stored relative to one another and wherein the actually transported fluids are checked for compatibility with one another by means of the monitoring unit based on the compatibilities stored in the database. It is known that medications to each other are not necessarily compatible, d. H. that certain medications may not be mixed together. This aspect can be taken into account by the fact that these drugs can not be mixed together and possibly administered to the patient via separate approaches. By means of the monitoring unit, it is now possible to detect such incompatibilities and to check accordingly. For example, upon detection of an incompatibility, a warning message may be issued to the user or caregiver via a corresponding output device.

Furthermore, it can be provided that the monitoring unit is connected in operation to a patient data management system. By means of the patient data management system, for example, it is easy to inquire which medication was prescribed for the patient. Based on this information, it becomes possible to perform detailed monitoring. In addition, it is also possible to transfer the course of treatment into the patient data management system by connecting to the patient data management system.

In addition, it can be provided that the monitoring unit matches the control data record with the state of the connection and with a medication stored in the patient data management system and the optical and / or electronic identification marking the transported medical fluid. This makes it possible to compare the medication actually administered with the planned medication and to check here accordingly. Furthermore, it is also possible to examine the prescribed medication with regard to the corresponding amount administered and to discover and prevent corresponding incorrect medications.

In addition, it can be provided that the monitoring unit has an optical monitoring element, and that the connecting and / or connecting tap has an optical marking, by means of which the position of the cock can be read out by means of the optical monitoring unit. This makes it possible to detect an incorrectly set cock, as by means of the monitoring unit based on the optical monitoring element, such as a camera, it is now recognizable which position the cock has. Since the monitoring unit is able to determine a necessary position of the tap itself on the basis of the planned data, the planned tap position can be determined by the monitoring unit and can actually be compared to that by means of the monitoring unit optical monitoring element determined position of the cock adjusted and thereby checked.

Further details and advantages of the invention will now be explained in more detail with reference to an embodiment shown in the drawings.
