Description

[0001] The invention relates to a data acquisition system for acquiring patient data. Furthermore, the invention relates to a method for acquiring patient data.

[0002] Data acquisition systems for capturing patient data are generally known. Typically, data from various sensors is sent to a patient monitor, where it is collected and stored in a digital database. It is also known to combine patient data into combined data and evaluate it accordingly.

[0003] Against this background, DE 10 2007 045 140 A1 describes, as an example, a mobile physiological data acquisition system for obtaining a patient's electrophysiological signals. Patient data is sent to a patient monitor via a data bus to enable joint evaluation and storage of these patient data.

[0004] Wireless sensors for patient monitoring are also known. However, in everyday clinical practice, cable-based data transmission is preferred due to its reliability and the ability to provide continuous, real-time transmission.

[0005] The object of the present invention is to provide an improved data acquisition system, in particular a data acquisition system that can be better adapted to a current patient situation.

[0006] According to a first aspect of the invention, a data acquisition system for acquiring patient data of a patient comprising a plurality of physiological sensors and a data collection unit is proposed to achieve this object.

[0007] The plurality of physiological sensors is configured to acquire patient data by means of electrodes, wherein at least two physiological sensors of the plurality of physiological sensors and / or adapter cables for a respectively assigned physiological sensor of the plurality of physiological sensors are arranged and configured to be directly connected to one another via a plug connection, thereby forming a sensor group. A sensor group configured according to the invention thus has at least two physiological sensors that acquire or generate patient data. The sensor group and / or the plug connection is configured to provide at least one measurement signal, preferably a plurality of measurement signals, and a reference signal from the electrodes. The or each measurement signal can be an analog or digital signal. The reference signal can be an analog or digital signal.

[0008] The physiological sensors can be provided as part of an ECG system, EIT system or SEMG system.

[0009] The data collection unit is designed to have at least one slot for a plug connection as a patient data interface, wherein the patient data determined by the sensor group are output to the data collection unit via a common plug, and wherein the common plug is designed for a direct plug connection to the data collection unit, for a plug connection to a hub for the data collection unit and / or for a plug connection to an adapter cable for the data collection unit.

[0010] Within the scope of the invention, it was recognized that in everyday clinical practice, a growing number of sensor cables in the vicinity of patients hinders workflows and, for example, complicates the repositioning or transport of a patient. This problem is solved by optimizing a tree structure of cables in the immediate vicinity of the patient while maintaining the measurement signal and reference signal. Thus, the provision of a sensor group with a common connector allows for a reduction in the number of plug-in spaces and cables.

[0011] For the purposes of this application, a tree structure is a structure in which several branches are connected from one or more basic elements to connecting elements connected to the basic elements, so that the idealized shape of a tree or bush is obtained.

[0012] This can advantageously reduce the effort required to transport a patient, in particular by reducing the number of connectors that need to be regrouped. This can also reduce the risk of user errors in everyday clinical practice.

[0013] Furthermore, an optimized tree structure of cables can reduce the material expenditure in the treatment of patients.

[0014] Finally, the inventive formation of at least one sensor group comprising at least two physiological sensors for detecting patient data allows for simple and rapid modification of the cable tree structure. Such modularity of the data acquisition system enables particularly advantageous rapid adaptation of the data acquisition system to a new patient treatment situation. In particular, the data acquisition system can be quickly adapted, for example, when the patient is transferred to or leaves the operating room or intensive care unit.

[0015] In the advantageous case of using patient cables, the modularity of the data acquisition system allows, for example, a short-term change in the number of leads used for the patient data.

[0016] A physiological sensor (hereinafter sometimes referred to simply as a sensor) is understood in the context of this invention to be a device with which a physiological measurement variable of a patient can be detected, which is based on the patient's electrical activity, for example the patient's heart muscle, and makes this available to obtain patient data. With the help of such a physiological sensor, patient data is thus determined, which comprises one or more measurement signals and a reference signal. Each individual sensor can perform an analog / digital conversion and / or output analog data. In this sense, a physiological sensor can also detect several different and / or similar measurement variables of a patient.For example, a patient cable with a plurality of electrodes can be a single physiological sensor within the scope of this invention. It is particularly possible that, in order to provide the reference signal, a preferably analogue reference potential is transmitted as a reference signal between the individual sensors by means of the plug connection.

[0017] For the purposes of this invention, an adapter cable is understood to be a cable that connects a first electronic component to a second electronic component. In this sense, an adapter cable can be an extension cable, a sensor cable, and / or a cable that connects various connectors to one another.

[0018] Patient data is data related to the patient. As such, patient data can include measured values ​​such as body temperature, blood pressure, heart rate, or the like, but also measured values ​​for further analysis, such as a measurement signal or reference potential within the scope of an examination using an ECG, EIT, SEMG, or the like. It is also conceivable that such patient data may contain information such as the patient name, a patient ID, a hospital department name, and / or a bed identifier, for example, a bed number.

[0019] In the sense of the invention, a slot can be a male or a female part of a connector.

[0020] Preferred embodiments of the data acquisition system according to the invention are described below.

[0021] In a particularly preferred embodiment, the data collection unit is further configured to output the acquired patient data to a database via a wireless data connection. In this embodiment, the data collection unit advantageously forms a central interface for communication with the database. This makes it possible to reduce the number of interfaces to the database and thus reduce the complexity of data acquisition in everyday clinical practice. The database is preferably stored on an external or internal memory. Wireless communication with the database can take place, for example, via a Bluetooth connection, a WLAN connection, and / or the like. Alternatively or additionally, the data acquisition system according to the invention can provide a wired connection to the database. Communication with the database preferably takes place via a hospital network.

[0022] In a further advantageous embodiment, the data collection unit is further configured to receive patient data from at least one of the plurality of physiological sensors via a wireless communication connection. Such a wireless communication connection can further reduce the number of cables in the patient environment.

[0023] Preferably, the at least two physiological sensors of the wireless communication connection comprise a communication interface to the database, the data of which can also be received with a certain time delay without endangering the health of the patient, such as in the case of a diagnosis.

[0024] Preferably, the at least two physiological sensors are configured to exchange and / or forward and / or provide a reference signal via the plug connection.

[0025] In a particularly preferred embodiment, the data acquisition system further comprises a hub which can be connected to the data collection unit via the at least one slot and which is designed to provide a respective plug connection to the sensor group, to a physiological sensor and / or to the adapter cable for a respectively assigned physiological sensor via a plurality of slots. The hub in this embodiment allows the tree structure of cables in the immediate patient environment to be further optimized. This allows a reduction in the number of cables and / or a reduction in the number of plug connections on the data collection unit. In an advantageous variant of this embodiment, the hub also serves as an analog / digital converter for the patient data output by the physiological sensors.A multitude of different designs of hubs are known to those skilled in the art, so they will not be discussed in detail below.

[0026] In a further particularly preferred embodiment, the data collection unit is supplied with energy, in particular via a battery. A battery is, for example, an accumulator. In this embodiment, the data collection unit can actively manage the storage and / or further processing of recorded patient data. This distinguishes the data collection unit according to this embodiment from passive data interfaces that merely forward data. Supplying the data collection unit via a battery advantageously allows for fail-safe operation in the event of an external power supply being interrupted. In a particularly advantageous variant, the data collection unit is supplied with energy both via a battery and via a power pack connected to an external power supply. This ensures the functionality of the data collection unit particularly reliably.

[0027] In a further embodiment, an analog / digital conversion of at least a portion of the acquired patient data takes place within one or both physiological sensors and / or within at least one adapter cable of the adapter cables, preferably for one or more respectively assigned physiological sensors. In this embodiment, it can be ensured that the data received by the data collection unit is already available in digital form, whereby both the measurement signal and the reference signal can be received by the data collection unit. It is possible to digitize only the measurement signal or all measurement signals and provide them to the data collection unit, and to provide the reference signal to the data collection unit in analog form.Examples of implementing such an analog-to-digital conversion, but without the described exchange and / or forwarding and / or provision of the reference signal, are familiar to those skilled in the art and will therefore not be explained in detail below. Reference is made to the publications DE 10 2016 005 324 A1 and US 2017 / 316671 AA for examples.

[0028] In a further advantageous embodiment, the at least one slot of the data collection unit is designed as a USB slot with an additional pin for the reference signal. The provision of a USB slot advantageously enables the use of known transmission protocols and thus inexpensive production of the data collection unit. Preferably, a further slot is provided in addition to the at least one USB slot. The further slot can be designed to receive the reference signal in addition to or as an alternative to the additional pin for the reference signal.

[0029] The slot or the additional slot is a component of the corresponding connector, whereby this component can be the female or the male part of the corresponding connector.

[0030] In a particularly preferred embodiment, at least one sensor from the plurality of sensors is formed from a patient cable with a plurality of electrodes, in particular with three or four electrodes. This patient cable can be supplemented by a further sensor for a lead with a plurality of electrodes. The data acquisition system according to the invention is particularly advantageous for use with a patient cable according to this embodiment. The advantageous use of sensor groups enables different patient cables to be connected via a corresponding plug connection. The number of leads of the corresponding measurement signal can thus be adapted depending on the patient's current situation. The modularity of the data acquisition system according to the invention thus ensures corresponding modularity of the examination performed.In addition, the data acquisition system in this embodiment allows for savings in material for the patient cables, since not every patient cable needs to be routed to a common connector. Since patient cables are often disposed of after a single use, the use of shorter cables can advantageously prevent waste.

[0031] In a particularly preferred variant of the preceding embodiment, the sensor group comprises at least two patient cables connected to one another via the plug-in connection, such that an (n+m-1) lead measurement signal and a reference signal, i.e. an (n+m) lead, can be acquired by the data acquisition system from a first patient cable with n electrodes and a second patient cable with m electrodes. This variant advantageously shows how the change in the tree structure of cables made possible by the data acquisition system according to the invention enables a change in the lead of the measurement signal and the reference signal. In this way, the examination carried out can always be adapted to the patient's current treatment situation. In particular, the number of leads can be changed, for example, when the patient leaves the intensive care unit.To combine the corresponding patient potentials of the measurement signals, the slots used preferably have a transmission channel for the existing neutral potential in addition to the USB lines (5V, GND, D+, D-). Furthermore, it is conceivable that data transmission could be carried out alternatively or in addition via SPI, I. 2 C, UART, RS232, LAN, WLAN or Bluetooth.

[0032] In one advantageous example, a patient cable with three electrodes is combined with another patient cable with three electrodes to enable a 6-fold derivation. In this example, the two patient cables form a sensor group connected to each other via a plug-in connection. This sensor group can, for example, be expanded with a patient cable with four electrodes to form a sensor group consisting of three patient cables to provide a measurement signal with a 9-fold derivation as well as the reference signal, i.e. a total of a 10-fold derivation. Accordingly, depending on the course of treatment, this sensor group can be reduced again by one or more patient cables to provide a reduced derivation during the examination.According to the invention, this adjustment of the signal derivation can be achieved without having to make any changes to the direct connectors of the data collection unit and / or a hub of the data collection unit. The connectors, which allow the sensors and / or adapter cables for a respective sensor to be directly connected to each other, reduce the workload in everyday clinical practice. This allows the cable tree structure to be changed quickly and easily without the need for laborious reconnection of cables on the data collection unit or a corresponding hub.

[0033] According to a second aspect of the invention, a method for recording patient data of a patient is proposed to achieve the above-mentioned object, comprising the steps: - Providing a plurality of physiological sensors with a plurality of electrodes for determining the patient data; - signal-technical connection of at least two physiological sensors and / or adapter cables for a respective associated physiological sensor with each other directly via a plug connection in order to form a sensor group; - Outputting the patient data determined by the sensor group to a data collection unit via a common connector, wherein the common connector connects the sensor group directly to the data collection unit, the sensor group to a hub for the data collection unit and / or the sensor group to an adapter cable for the data collection unit.

[0034] The method according to the invention is carried out by the data acquisition system according to the first aspect of the invention and comprises the explained advantages of this data acquisition system. In particular, by connecting sensors and / or adapter cables for a respective sensor to a sensor group, the method according to the invention allows for a particularly simple and clearly structured tree structure of cables in the immediate vicinity of the patient. This can reduce the effort required to connect the patient to a corresponding data acquisition system. Furthermore, this can prevent errors when providing the plug connections for the data acquisition system.

[0035] The method according to the invention is preferably carried out in the specified order. Individual steps, such as the signal-technical connection of at least two physiological sensors and / or adapter cables for a respective associated physiological sensor, can preferably be carried out manually.

[0036] In a particularly preferred embodiment, a final step of the method according to the invention comprises wirelessly outputting the acquired patient data to a database. In this embodiment, the data collection unit enables central communication with the database for storing and managing the patient data. This avoids the need for multiple interfaces to the database. Preferably, communication with the database takes place via a hospital network.

[0037] In another particularly preferred embodiment, a preceding step comprises a unique assignment of the data collection unit to the patient. This preceding step is preferably carried out via a software protocol. This unique assignment advantageously reduces the complexity of the tree structure of cables in the patient's environment, since the data collection unit is not connected to cables from multiple patients. In a preferred variant of this embodiment, only one data collection unit is advantageously assigned to a patient.

[0038] This allows the data collection unit to form a central location for collecting, managing and / or further processing patient data of a specific patient.

[0039] In a further embodiment, an analog-to-digital conversion is performed for at least some of the acquired patient data between its acquisition at the respective physiological sensor and its reception by the data collection unit. This analog-to-digital conversion allows the patient data to be easily further processed digitally by the data collection unit.

[0040] In a further advantageous embodiment, the step of signal-technically connecting at least two physiological sensors and / or adapter cables for a respectively assigned physiological sensor is performed multiple times in order to form a sensor group comprising more than two physiological sensors and / or multiple sensor groups. In this embodiment, multiple plug connections are advantageously used to group sensors and / or adapter cables for a respective sensor. By using multiple plug connections between sensors and / or adapter cables, the tree structure of cables on the patient can advantageously be optimized, thus, in particular, reducing the complexity of the tree structure.

[0041] The invention will now be explained in more detail with reference to advantageous embodiments schematically illustrated in the figures. These show in detail: Fig. 1 is a schematic representation of a first embodiment of a data acquisition system according to a first aspect of the invention; Fig. 2 is a schematic representation of a second embodiment of the data acquisition system according to the first aspect of the invention; Fig. 3, Fig. 4, Fig. 5 is a schematic representation of a third embodiment of the data acquisition system according to the first aspect of the invention, wherein a patient cable ( Fig. 3) with a second patient cable ( Fig. 4) and with a third patient cable ( Fig. 5) is combined; and Fig. 6 a flowchart of an embodiment of a method according to a second aspect of the invention.

[0042] Fig. 1 shows a schematic representation of a first embodiment of a data acquisition system 100 according to a first aspect of the invention.

[0043] The data acquisition system 100 is designed to acquire patient data 105, in particular ECG data, of a patient 102. For this purpose, it comprises a plurality of physiological sensors 110 and a data collection unit 130.

[0044] The plurality of sensors 110 are configured to acquire patient data 105. In the illustrated embodiment, these are two physiological sensors 111, 112 for acquiring patient data 105 using electrodes 111a, 112a, and a third sensor 113 for measuring a temperature of the patient 102. These three sensors 111, 112, and 113 all rest against the skin of the patient 102 and are exemplary of a multitude of known sensors. According to the invention, at least two physiological sensors 111, 112 are arranged and configured to be directly connected to one another via a plug connection 115, thereby forming a sensor group 116. One or more measurement signals and / or a reference signal can be exchanged, forwarded, and / or provided via the plug connection 115.Alternatively or additionally, at least two adapter cables for a respective associated physiological sensor can be arranged and configured to be directly connected to each other via a plug connection, thereby forming a sensor group. Such adapter cables are shown, for example, in the . Fig. 3, Fig. 4 and Fig. 5 shown.

[0045] The data collection unit 130 is designed to have at least one slot 132 for a connector 133 as a patient data interface. Fig. Figure 1 shows three slots 132 of the data collection unit 130 as an example. The slots may be parts of a manufacturer-specific connector and / or connectors commonly available on the market and compatible with other devices. For example, the slot may be a USB port.

[0046] According to the invention, the patient data 105 determined by the sensor group 116 are output to the data collection unit 130 via a common connector 120. Thus, in the illustrated embodiment, the patient data 105 determined by the sensor 111 and the sensor 112 are output via the common connector 120, wherein the patient data 105 from the sensor 111 have previously reached the connector 120 via the connector 115. The measurement signal(s) and the reference signal can be combined or transmitted separately. In the present case, the output via the common connector 120 is to be effected by a direct connector connection to the data collection unit 130. Alternatively, the common connector can also be connected via a hub, as in Fig. 2, or via an adapter cable as shown in Fig. 3, be connected to the data collection unit 130. In embodiments not shown, several data collectors are provided in the data acquisition system, in particular combined via a corresponding plug connection.

[0047] In the illustrated embodiments, the plug connections are generally shown unconnected for reasons of clarity and to simplify the illustration.

[0048] The third sensor 113 is not part of the sensor group 116, but is connected to the data collection unit 130 via a separate connector. The slots 132 provided by the data collection unit 130 can be identical or at least partially different.

[0049] In the illustrated embodiment, the data collection unit is further configured to output the acquired patient data 105 to a database 140 via a wireless data connection 136. In the present case, this output occurs via a hospital network 145, which is connected to the database 140. Communication with the hospital network preferably occurs via Bluetooth, WLAN, or the like. Alternatively, this output can also be made directly to the database or a corresponding external device. The database 140 is preferably part of the data acquisition system 100, but in other embodiments according to the invention, it is also present as an external database.

[0050] Fig. 2 shows a schematic representation of a second embodiment of the data acquisition system 200 according to the first aspect of the invention.

[0051] The data acquisition system 200 is similar to that in Fig. 1. Data acquisition system 200 differs from data acquisition system 100, among other things, in that data collection unit 230 of data acquisition system 200 is further configured to receive patient data 105 from at least one physiological sensor 214 of the plurality of physiological sensors 110 via a wireless communication connection 239. Preferably, a data interface 238 of data collection unit 230 allows, in addition to the wireless communication connection 239 with sensor 214, wireless communication with other sensors (not shown) from the plurality of sensors 110. Physiological sensor 214 has an electrode 214a.

[0052] In addition, the data acquisition system 200, unlike the data acquisition system 100, has Fig. 1, a hub 250, which can be connected to the data collection unit 230 via at least one slot 132. The hub 250 is designed to provide a respective plug connection to the sensor group 116, to a physiological sensor 113, and / or to the adapter cable for a respectively assigned physiological sensor via a plurality of slots 252, namely, in this case, two slots 252. The hub 250 also has a hub connector 254 to be connected to a slot 132 of the data collection unit 230. The hub 250 can, as in Fig. 2, may be provided as a compact box with a housing. Alternatively or additionally, the hub may be designed as a signal-technical connection of a plurality of cables or the like. Advantageously, the hub 250 allows an increase in the number of slots available for the data collection unit 230. Furthermore, the hub 250 can expand the application area of ​​the data collection unit 230 through special types of slots. In particular, plug connections that were not yet provided for the data collection unit 230 can also be used for the inventive acquisition of the patient data 105 by retrofitting them with a corresponding hub.

[0053] Finally, the data collection unit 230 of the data acquisition system 200 is also supplied with power, in particular via a battery (not shown). In addition to the battery, a power connection 260 is also provided on the data collection unit 230. The power supply can be via the general mains voltage and / or via Power over Ethernet. This provides the energy required for the operation of the data collection unit 230 in a particularly safe and reliable manner.

[0054] A preferred analog / digital conversion for further processing of the patient data 105 acquired by the plurality of sensors 110, in particular the patient data 105 generated by the sensor group 116 comprising a plurality of physiological sensors, preferably takes place within the respective sensor 111, 112, 113, 214, and / or within the adapter cable for one or more respectively assigned physiological sensors 111, 112, 113, 214. This ensures that the data collection unit 230 preferably receives digital patient data 105 directly and can forward and / or store it. In an embodiment not shown, the analog / digital conversion of the patient data 105 only takes place in the data collection unit 230.

[0055] The Fig. 3, Fig. 4 and Fig. 5 shows a schematic representation of a third embodiment of the data acquisition system according to the first aspect of the invention, wherein a first patient cable ( Fig. 3) with a second patient cable ( Fig. 4) and with a third patient cable ( Fig. 5) is combined.

[0056] The Fig. The use of a single patient cable 370 for the data acquisition system 300 according to the invention shown in Figure 3 only shows the use of a sensor 111 in the form of the patient cable 370 with three electrodes.

[0057] This arrangement therefore enables the acquisition of a 3-lead ECG measurement signal.

[0058] An adapter cable 371 is directly assigned to the patient cable, which, in the illustrated case, also acts as an analog / digital converter for digitizing the acquired patient data 105. Since such patient cables are typically combined with such an adapter cable 371, this adapter cable 371 can also be present as part of the patient cable.

[0059] The inventive combination of sensors 111, 112 to form a sensor group 116 is shown in Fig. 4, in which the data acquisition system 300 of Fig. 3 is supplemented by a second patient cable 472 to the data acquisition system 400.

[0060] The second patient cable 472 is connected to the first patient cable 370 by a plug connection 115 via the corresponding adapter cables 371, 473, so that these two patient cables 370, 472 form the sensor group 116 and can be connected to the data collection unit 330 via a common plug 120. As an alternative to the direct connection, Fig. 3, Fig. 4 and Fig. 5 also shows two different additional adapter cables 380, 382 and the hub 350, which can be interposed between the common connector 120 and the data collection unit 330.

[0061] The combination of the two patient cables 370, 472 ensures that by simply plugging in a patient cable the number of leads can be increased to a 5-lead measurement signal with a reference signal, i.e. to a 6-fold lead.

[0062] In Fig. Figure 5 shows an addition of an additional patient cable 574 to the data acquisition system 400. This creates a sensor group 116 consisting of three patient cables 370, 472, 574. This further increases the number of leads of the corresponding signals to a corresponding 10-fold lead.

[0063] The exact arrangement of the respective electrodes of a patient cable is shown in the Fig. 3, Fig. 4 and Fig. 5 is only presented in an idealized manner.

[0064] In principle, the data acquisition system according to the invention can comprise multiple hubs, multiple adapter cables, and / or other interposed electronic components. These components can be combined and connected in series for individual or multiple sensors.

[0065] Fig. 6 shows a flowchart of an embodiment of a method 600 according to a second aspect of the invention.

[0066] The method 600 according to the invention is designed to acquire patient data 105 of a patient. For this purpose, it comprises the steps explained below.

[0067] A first step 610 comprises providing a plurality of physiological sensors with a plurality of electrodes for determining the patient data 105.

[0068] A subsequent step 620 comprises a signal-technical connection of at least two physiological sensors 111, 112 and / or adapter cables 371, 473 for a respectively assigned physiological sensor 111, 112 to one another directly via a plug connection 115 to form a sensor group 116.

[0069] A further step 630 comprises outputting the patient data 105 determined by the sensor group 116 via a common connector 120 to a data collection unit 130, wherein the common connector 120 connects the sensor group 116 directly to the data collection unit 130, the sensor group 116 to a hub 250 for the data collection unit 130 and / or the sensor group 116 to an adapter cable 371 for the data collection unit 130.

[0070] Preferably, method steps 610, 620, and 630 are performed in the specified order. At least step 620 is preferably performed manually.

[0071] The method 600 according to the invention is preferably finally supplemented by a wired or wireless output of the acquired patient data 105 to a database 140. Alternatively or additionally, the acquired patient data 105 can also be stored in the data collection unit 130 or in another device connected to the data collection unit 130, such as a patient monitor.

[0072] In a particularly advantageous embodiment, a step preceding method 600 comprises a unique assignment of data collection unit 130 to a patient. Preferably, there is also a unique assignment of the patient to data collection unit 130, so that during a hospital stay, all relevant physiological patient data 105 of a patient are recorded via this data collection unit 130.

[0073] Not shown in Fig. 6 an analog / digital conversion of the determined patient data 105, which preferably takes place between the determination at the respective sensor 111, 112 and the reception by the data collection unit 130.

[0074] In a preferred variant of the method 600, the step of signal-technically connecting at least two physiological sensors 111, 112 and / or adapter cables 371, 473 for a respectively assigned physiological sensor 111, 112 is carried out multiple times in order to form a sensor group 116 from more than two physiological sensors 111, 112 and / or several sensor groups 116.
