Description

TECHNICAL FIELD

[0001] The present disclosure relates to a holding device for holding and fixing at least one electronic end device with an integrated charging unit during a dialysis treatment. BACKGROUND

[0002] During dialysis, patients stay on a bed next to the dialysis machine for about four to five hours. Since patients have to undergo dialysis up to 3 times a week, this results in a high weekly time investment within the dialysis center. Due to these time constraints, patients sometimes react very irritably if the treatment time is longer than usual. Furthermore, the schedule is strictly timed, like a taxi for example, which is already waiting to take an individual patient home.

[0003] Most patients spend 12 to 15 hours a week in the dialysis center watching TV, listening to music, reading or sleeping on a TV set installed there. The TV set is usually installed in such a way that three to four patients can / must watch at the same time and therefore have to agree on the TV program.

[0004] The increasing digitalization of mobile end devices and the associated widespread availability also goes beyond patients in dialysis centers. In particular, in order to make their time during dialysis more enjoyable, they also widely use mobile electronic devices such as smartphones, e-book readers and tablet computers.

[0005] In particular, the trend to be able to use more and more services "on demand" and thus to watch series and movies at any time provides an attractive opportunity to combine the dialysis time with a pleasant leisure activity. Therefore, it can be expected that more and more people in dialysis centers will make their time more enjoyable by using mobile end devices.

[0006] However, larger media applications such as streaming / on-line movies and series or playing mobile games, for example, sometimes consume a lot of energy / charge the battery, so that the conventional rechargeable batteries of mobile end devices are quickly depleted. In particular, because the development of rechargeable batteries is slower than in other areas / disciplines of entertainment electronics, the ability to charge the devices more quickly becomes more and more important.

[0007] Therefore, if a patient wants to charge his / her mobile end device, he / she has to carry his / her own charger in the form of a mobile power supply / external energy storage medium with him / her. In most cases, it is forbidden to connect the charger to the dialysis center's own power outlet, because unapproved devices can cause power failures within the dialysis center or, in the event of a failure, damage the dialysis center's fuses, with a negative or even dangerous impact on the patients being treated at the time. In addition, short circuits triggered by such devices can also cause fires.

[0008] Thus, the patient makes the waiting time during dialysis more pleasant by using his / her own mobile terminal device, relying on the chargeable battery capacity of his / her device. If the chargeable battery capacity reaches a minimum and the patient has no charging option, he / she cannot continue using his / her device. As a result, the patient's mental state sometimes deteriorates dramatically, as he / she is now unable to do any desired leisure activities. Furthermore, in the case of a chargeable smartphone battery running out, he / she cannot be reached by others or they cannot reach him / her. These people can be, for example, relatives or friends who have to pick up the patient after the treatment and can be late.

[0009] Furthermore, if the dialysis center allows the patient to connect his own charger to the internal power supply system, they take a risk. In particular, low-quality or defective products can, in the worst case, cause a power failure within the center. Furthermore, if the patient is able to use his / her own device, he / she has to make sure that a power outlet is located at a suitable distance from his / her dialysis station. Furthermore, the patient has to hold the device in his / her hand, for example, at all times in order to be able to use it to watch a series of programs. It is usually not possible to accurately determine on which side of the machine the patient is. Therefore, the cable can be distracting or too short to extend from the outlet to the patient.

[0010] WO 2017 / 064 251 A1 describes a medical system which allows a patient to safely power an external electronic terminal device during treatment. Here, an electrically insulated power outlet is provided on the machine housing, so that a mobile terminal device can be charged via a cable.

[0011] DE 10 2012 020 945 A1 describes how a mobile terminal device can be attached to a liquid management device to replace a display and input unit. However, the mobile terminal device is no longer available to the patient for entertainment purposes.

[0012] WO 2017 131 796 A1 discloses a multifunctional nurse call system to which a mobile terminal device can be connected. However, any medical device cannot be read or controlled with it. Furthermore, in this case, no wireless power transfer for charging a mobile terminal device is provided.

[0013] CN 108 186 232 A describes a hospital bed with a storage area on which a mobile terminal device can be wirelessly charged.

[0014] CN 107 948 370 A describes a terminal device holder with an integrated chargeable battery for fixing and charging a mobile terminal device. SUMMARY

[0015] It is therefore an object of the present application to avoid or at least reduce the disadvantages caused by the prior art. In particular, a fixing device should be provided which is designed to secure an electronic end device during a dialysis treatment and at the same time and safely to power it.

[0016] The medical device, preferably a dialysis machine, is understood to mean, inter alia, a conventional hemodialysis or hemodiafiltration device. Furthermore, the holding device can also be used in combination with other devices, such as a peritoneal dialysis device, an acute dialysis device or an apheresis device. In the following, for the sake of simplicity, the medical device is replaced by the term dialysis machine.

[0017] According to the application, this object is achieved by a holding device for holding and securing at least one electronic end device, in particular of the entertainment electronic type, during a medical, more specifically dialysis treatment, which is or can be attached to a medical device, such as a dialysis machine, or to a patient bed with an integrated charging unit which is set up and designed to power the held and / or secured electronic end device more specifically from the medical device, wherein a protection circuit is integrated in the holding device to detect defects of the just connected end device.

[0018] In other words, the holding device accommodates a protection circuit with electrical protection mechanisms, such as temperature sensors, which protect the mobile end device and the dialysis machine from overvoltage, undervoltage, short circuit or thermal damage. Here, the protection circuit serves to monitor the clamped / in use mobile end device to protect both the mobile end device, the patient and the dialysis machine and its environment. The advantage of placing the protection circuit in the holding device is that, due to this decoupling, the mobile end device cannot cause damage to the dialysis machine.

[0019] Alternatively or additionally, preferably, the holding device has already been supplied with a low voltage, for example 5 V, to charge the end device. In this way, a protection circuit which preferably only monitors the charging current can be integrated in the treatment device. In the case of the use of a rechargeable battery, then two protection circuits will be used. In this case, a first protection circuit is provided in the holding device for monitoring the charging process of the mobile end device and a second protection circuit is provided in the medical device for monitoring the charging process of the rechargeable battery.

[0020] In other words, the patient should have the opportunity to safely power his / her mobile end device via the holding device connected to the machine or patient bed. In this case, a mounting of a fixing device is provided which is connected to the machine or patient bed and serves a mobile end device, such as a smartphone, tablet computer, e-reader, etc. In addition to the power supply, the holding device also allows the mobile end device to be charged during the dialysis treatment.

[0021] The advantage of the solution is that patients can charge their mobile terminal device at any time, making their time during dialysis treatment more comfortable. Patients do not have to worry that their mobile terminal device malfunctions due to a lack of chargeable battery capacity. Furthermore, dialysis centers do not have to worry about using chargers specifically brought on the home network. In other words, the advantage is that an external power supply is provided without affecting safety.

[0022] The holding device is preferably designed with a front cover plate and a rear cover plate, which are connected to each other by a joint / hinge on one side and can be pivoted relative to each other. The front cover plate is designed by a frame with a closed rear side. The frame is designed in such a way that it accommodates the mobile terminal device. On the opposite side of the joint, the front cover plate is connected to the rear cover plate by an (length) adjustable bottom. This allows the patient to place the holding device at the desired angle on a flat base / surface.

[0023] The adjustable bottom is preferably designed to flexibly adjust the setting angle of the mobile terminal device by a ribbed / grooved surface or a set screw. Thus, the set screw is designed to be integrated in the bottom so that it is flexibly moved and tightened. For example, the movement of the set screw is provided by a guide rail integrated in the bottom. Furthermore, the invention proposes that the bottom has a corresponding length / depth in order to also use large setting angles, preferably more than 90°, more preferably more than 120°. The advantage is that the holding device also remains stable on soft bases such as a mattress.

[0024] Advantageous embodiments are claimed in the dependent claims and explained in more detail hereinafter.

[0025] Preferably, the holding device, the electronic terminal device and the dialysis machine are designed and intended to communicate with each other in order to transmit data, preferably bidirectionally, between the dialysis machine and the electronic terminal device. In other words, the holding device is designed as a smart holding device, which provides a data exchange or communication link between the dialysis machine and the mobile terminal device.

[0026] Preferably, the data to be transmitted are treatment-specific data / information. The input and display device has different display elements and buttons for inputting and displaying data / information. Thus, the display elements can for example display the progress of the dialysis treatment and the buttons can be used to call a medical staff.

[0027] Furthermore, the data to be transmitted include for example information about the fluid intake of the patient during the dialysis treatment. This information can in turn be inputted by a button on the input and display device. Since one goal of the dialysis treatment is to remove excess water from the patient, the fluid intake can be directly taken into account by increasing the ultrafiltration amount consumed by the fluid amount. Another advantage is that the additionally required ultrafiltration amount can be evenly distributed over the remaining treatment time.

[0028] Such integrable comfort functions, such as reading off the course of treatment, and the direct and immediate transmission of information between the dialysis machine and the mobile terminal device or holding device, provide for a more pleasant and efficient dialysis treatment for the patient.

[0029] For example, buttons are available on the display device for a beverage of a predetermined volume of up to 150 ml, for a medium-sized beverage of a volume of between 150 ml and 250 ml, and for a large-sized beverage of a volume of more than 250 ml (up to 400 ml). Of course, the volume of the beverage can also be entered directly by means of numbers or by using a button designed as a slider bar.

[0030] Furthermore, it is preferred that the food intake during the treatment is also processed in a similar manner in order to be adjusted directly. In particular, if the patient consumes / eats, for example, a piece of fruit or a cake, etc., in which it is at least approximately known how much potassium and / or sodium is contained therein, the patient can communicate this to the dialysis machine by means of the display and input device. This dialysis machine is then designed to adjust the composition of the dialysis liquid such that the amount of potassium and / or sodium and / or another electrolyte contained in the fresh dialysis liquid (consumed by the food) is removed again during the further course of treatment.

[0031] It is further preferred that the terminal device can also be used for patient identification and thus take over the function of a patient card, for example, as known from the prior art. For example, based on this identification, treatment parameters can be downloaded from a data management system of a dialysis center to the dialysis machine. Alternatively, these parameters / this data can also be stored directly on the terminal device, from which they are transmitted to the dialysis machine.

[0032] It is preferred that the holding device is arranged and designed to clamp the mobile terminal device in order to enter different position postures, preferably by means of a swivel arm / holding arm, or in order to be held in a set position posture. In other words, this means that the holding device preferably has two clamping elements which can be adjusted for different sizes of terminal devices and which are designed in such a way that the mobile terminal device can be held and fixed by the holding device due to the pressure exerted on the terminal device by the clamping elements. The clamping elements can be moved manually by the patient by means of a position holder protruding from the edge of the holding device in order to clamp terminal devices of different sizes. This has the advantage that the method of clamping is gentle on the terminal device and does not leave any damage.

[0033] It is advantageous that the holding device is attached to a multi-joint and a pivotable swivel arm / holding arm. In this case, the swivel arm is designed as part of the dialysis machine or as part of the patient bed. The swivel arm allows the patient to place the mobile terminal device clamped in the holding device in front of him / her, so that it does not have to be held or put down.

[0034] Furthermore, for example, this advantage lies in the fact that the patient does not have to hold the mobile terminal device constantly in his / her hand, since the holding device is designed in such a way that it can be stood up independently and / or placed on the knees. This ergonomic and comfortable holding device allows the patient to place the device comfortably for them without having to hold it constantly.

[0035] Preferably, the screen of the electronic terminal device is provided and designed as an input / display device and is freely accessible to the user and / or patient during the treatment. With this holding device of the mobile terminal device connected to the machine or the bed, the patient can safely power the device and still fix the mobile terminal device in a position that is comfortable for him / her and easy to access in order to be able to continue to use it as an entertainment means.

[0036] In this regard, the holding device is designed in such a way that the full operation of the mobile terminal device for the patient is still ensured. Assuming that he / she wants to spend his / her time using the mobile terminal device, this advantage lies in the fact that the overall feeling of the time spent and the quality of the dialysis is increased.

[0037] Preferably, the holding device is provided and designed to power the mobile terminal device by means of a cable connected to the dialysis machine or the bed or by means of an energy storage unit, preferably a rechargeable battery. In the case where the holding device has a separate energy storage unit, the energy storage unit is preferably charged between two treatments.

[0038] Furthermore, preferably, the charging holder has a wireless charging mechanism / energy transfer device. The charging holder is preferably attached to one side of the dialysis machine or to the bed, preferably to an arm support / handrail thereof. In other words, for example, a wireless method using induction can be used to charge the energy storage unit. The charging mechanism can also be attached to the dialysis machine in the form of another holder / charging holder. In this way, the energy storage unit of the holding device can be docked to the charging holder of the dialysis machine between each treatment in order to be recharged for the next treatment.

[0039] The charging holder allows the holding device to be attached to the dialysis machine in a frictional and / or interlocking manner. This includes, for example, a plug-in connection, a clamp or even a magnetic connection, a pocket or a clamp / hook into which the holding device is inserted / attached / fixed in order to charge the energy storage unit integrated therein.

[0040] Furthermore, preferably, the charging mechanism is located inside or outside the housing of the dialysis machine and has at least one coil integrated therein for / needed for wireless energy transfer by means of inductive or resonant inductive coupling. Here, general shielding measures are provided or implemented so that electromagnetic compatibility is ensured and surrounding medical and non-medical devices are not disturbed or disturbed.

[0041] It is further preferred that the charging holder is attached to the dialysis machine. The charging holder for wireless power transmission has an integrated coil, which is arranged in the housing of the dialysis machine or on the hospital bed and can be folded out by a hinge. When folded out, the mobile terminal device or the holding device, which can be inductively charged (without additional holding means), can be placed on the charging holder for charging. Once the charging is no longer required, the charging holder can be folded in.

[0042] Preferably, the holding device comprises at least one integrated circuit. The circuit comprises a charging circuit and a processing circuit and / or a fuse circuit.

[0043] In the case of the holding device being attached to the dialysis machine, the fuse circuit is arranged within the holding device and comprises a fuse mechanism protecting the mobile terminal device and the dialysis machine from overvoltage, undervoltage, short circuit or thermal damage.

[0044] In the case of the holding device being attached to the hospital bed, no fuse protection is required between the dialysis machine and the holding device, since the power supply of the holding device is provided by the hospital bed.

[0045] In the case of the holding device being powered by an energy storage unit, a fuse mechanism is located within the holding device to protect the mobile terminal device from overvoltage, undervoltage, short circuit and / or thermal damage. Furthermore, all necessary circuits for the correct control of the installed rechargeable battery and its charging circuit are arranged within the holding device. In this case, the advantage of the present application is that there are no interfering cables on the holding device and the charging holder provides fast charging without cables.

[0046] Thus, the holding device performs a safety monitoring and protects the mobile terminal device and the dialysis machine from electrical or thermal hazards.

[0047] In a preferred embodiment of the present application, the charging unit is designed with an integrated adapter / charging adapter, for example a USB connection, to allow electronic terminal devices of different models to be electrically connected to the charging unit. In other words, this means that the holding device allows the charging of the mobile terminal device carried along by means of an integrated charging adapter for different standards of mobile terminal devices.

[0048] Preferably, the holding device has a headphone connection. In other words, this means that an external connector / external connection for inserting headphones is provided on the holding device.

[0049] Preferably, the holding device is provided and designed to communicate and exchange data with the connected electronic terminal device by NFC (Near Field Communication, an international transmission standard for contactless data exchange based on RFID technology) and a corresponding application. In other words, the holding device can communicate and exchange information about the course of treatment with the connected mobile terminal device by NFC and a corresponding application. Information input by the patient, if any, for example whether the patient has consumed liquid during the treatment, can be transmitted directly to the machine to adjust the treatment or treatment parameters, in particular the ultrafiltration volume. The transmission preferably takes place by radio or Bluetooth. In this way, a staff call function can also be integrated into the holding device. It is preferred here that the ultrafiltration volume is adjusted, preferably automatically, directly based on the input at the electronic terminal device about the amount of liquid consumed by the patient.

[0050] The application further relates to a charging unit with a complete / integrated power supply unit on a dialysis machine or a hospital bed with a holding device according to any of the preceding aspects. In other words, the charging unit simultaneously serves as a power supply unit on a dialysis machine or a hospital bed with a holding device.

[0051] In summary, the application provides a holding device / terminal device holder in which as many common models of mobile devices as possible can be fixed. At the same time, the screen remains idle to allow the mobile terminal device to continue to operate. Furthermore, the application proposes that the fixed terminal device is powered by an adapter integrated in the holding device of various standards. Furthermore, electrical and thermal safety circuits (temperature sensor) are located inside the holding device. The holding device can be connected to the machine by a cable and powered. Alternatively, the power supply can also be connected to the bed or be realized by rechargeable batteries and a wireless charging holder, which is preferably attached to the machine or to the hospital bed.

[0052] In this case, the design is chosen such that the holding device can be independently stood up and placed in various positions, thus eliminating the need for the patient to hold it all the time. Alternatively, the holding device is attached to a swivel arm that is part of the machine or the hospital bed. An earphone connection can also be additionally integrated, as well as a quick input key. The quick input key can be used, for example, to adjust the volume or to press the forward / backward key.

[0053] The system can be expanded by a wireless interface by means of which the holding device, the dialysis machine and the mobile terminal device (NFC, Bluetooth, WLAN, etc.) can communicate with each other and exchange information about the course of treatment. BRIEF DESCRIPTION OF DRAWINGS

In Figure 1 and Figure 2 a holding device 1 for a dialysis machine 2 is provided to hold and secure a mobile terminal device 3.

[0066] The holding device 1 can be attached to a dialysis machine 2 according to a first embodiment (see Figure 9 ) or to a hospital bed (not shown) according to a second embodiment. According to the second embodiment, the attachment of the holding device 1 is preferably provided to an armrest / arm support.

[0067] As Figure 1 and Figure 2As shown, the holding device 1 has a frame 4 with a closed back side (in the following also referred to as front cover plate). The frame 4 accommodates the mobile terminal device 3, the clamping elements 12 and an integrated charging unit 5 with at least one charging adapter (not shown) for connecting the mobile terminal device 3 to the charging unit 5. The display and input device 6 is provided by the display / screen of the mobile terminal device 3. The mobile terminal device 3 is clamped in the holding device 1 by means of at least one, preferably two, clamping elements 12. The two clamping elements 12 are preferably arranged on the sides of the mobile terminal device 3 and are designed to be adjusted by lateral movement for the size of the mobile terminal device 3 to be clamped.

[0068] Alternatively, it is also conceivable to use only one clamping element 12. As a further alternative, it is conceivable to use at least one clamping element 12 arranged above and / or below the mobile terminal device 3 and the charging unit 5 accordingly on one side of the holding device 1. Furthermore, a magnetic holder for the mobile terminal device can additionally or alternatively be provided.

[0069] The holding device 1 is designed with a connection 9, preferably for a power cable. The connection 9 connects the holding device 1 to the dialysis machine 2 according to the first embodiment. In the second embodiment, the cable connects the holding device 1 to the patient bed. In both embodiments, the connection 9 provides the holding device 1 with power to power the held and / or fixed electronic terminal device 3.

[0070] The holding device 1 has at least one position holder 13 on the upper edge of the frame 4 of the holding device 1. As Figure 1 shown, the holding device 1 has two position holders 13. With these position holders 13, the patient can adjust the clamping elements 12 by moving them so that the mobile terminal device is held and fixed.

[0071] The frame 4 of the holding device 1 has at least one quick input key 14. According to Figure 1 and Figure 2 The quick input key 14 is preferably attached to the lower frame 4. The quick input key 14 can for example be related to the volume and / or forward / backward key. Alternatively, it is also conceivable that one quick input key 14 serves as a nurse call.

[0072] In Figure 1 and Figure 2 The charging unit 5 can alternatively be designed as a storage unit according to the third embodiment. In the case of the third embodiment, the connection 9 and the associated power cable are omitted, as described later.

[0073] Figure 3 is a schematic side view of the holding device 1. Figure 3The frame 4 of the holding device 1 is shown. The holding device 1 has a front cover plate 4 and a rear cover plate 22 formed by the frame 4. The front cover plate 4 is formed with the rear cover plate 22 that can be pivoted / folded relative thereto by a joint 15, and the circuit 8 is accommodated / integrated in the front cover plate 4. The front cover plate 4 and the rear cover plate 22 are connected on opposite sides of the joint 15 by an (length) adjustable bottom 16. Thus, the holding device 1 according to the third embodiment can be parked on a flat bed.

[0074] Figure 3 The front cover plate 4 of the holding device 1 shows the earphone connection 10 and the connection 9 for a (power) cable. At the same time, the circuit 8 is provided in the front cover plate 4. The circuit 8 has a charging circuit and a processing circuit and / or a fuse circuit.

[0075] The following Figure 4 to Figure 7 An example of a blood treatment machine / dialysis machine 2 with a charging holder 17 for the holding device 1 according to the third embodiment is shown. In this case, the charging holder 17 has a wireless charging mechanism / power transmission device 18. Figure 4 to Figure 8 Each shows the charging holder 17 on the left side of the dialysis machine 2.

[0076] For the charging holder 17, various embodiments are conceivable that allow a frictional and / or interlocking attachment of the holding device 1 to the dialysis machine 2. These include, for example, plug-in connections, clamps or even magnetic connections. Figure 4 A charging holder 17 is shown, which is designed as a pocket in which the holding device 1 is placed for charging the energy storage unit integrated therein. Figure 6 A pocket-like charging holder 17 is shown in which the holding device 1 is arranged.

[0077] Figure 5 A charging holder 17 is shown, which is designed as two clamps / hooks in which the holding device 1 is placed for charging the energy storage unit integrated therein. Figure 7 A clamp / hook-like charging holder 17 is shown in which the holding device 1 is positioned.

[0078] Figure 4 to Figure 7 The charging mechanism 18 can be located both inside and outside the housing of the dialysis machine 2 and has at least one coil integrated therein for wireless energy transmission by means of inductive or resonant inductive coupling. Here, general shielding measures are provided or implemented so that electromagnetic compatibility is ensured and surrounding medical and non-medical devices are not disturbed or disturbed.

[0079] The above-mentioned charging holder 17 can also be conceivable in a similar or identical design on a hospital bed, preferably on an arm support (not shown).

[0080] Figure 8 is a schematic view of a third charging holder 17 attached to the dialysis machine 2. As an additional embodiment, Figure 8 An enlarged view of a charging holder 17 for wireless energy transfer with integrated coil is shown, which is located on the housing of the dialysis machine 2 or on the patient bed and can be folded out by a hinge 19. In the folded-out state, the mobile terminal device 3, which can be charged inductively, can be placed on the charging holder 17 for charging. Here, the additional holding device 1 is not necessary. Once the charging is no longer required, the charging holder 17 can be folded in.

[0081] Alternatively, the folded-out charging holder 17 according to Figure 8 can be designed to charge the holding device 1 as soon as it is resting on the folded-out charging holder 17.

[0082] Figure 9 is a schematic view of a holding device 1 with a swivel arm 7 on the dialysis machine 2. The holding device 1 is attached to a multi-joint and a pivotable swivel arm / holding arm 7. The swivel arm 7 is designed as part of the dialysis machine 2 according to the first embodiment or as part of the patient bed according to the second embodiment (not shown). The swivel arm 7 allows the patient to place the mobile terminal 3 clamped in the holding device 1 in front of him / her, so that it does not have to be laid down or held by him / her.

[0083] Figure 10 is a schematic view of a user surface of the display and input device 6. Figure 10 An example of a possible user surface of an application program executed on the mobile terminal device 3 is shown. The user surface has various display elements 20 and buttons 21. For example, the display elements 20 show the progress of the dialysis treatment. The buttons 21 can be used to call a medical staff.

[0084] Furthermore, the liquid intake during the dialysis treatment can be reported to the dialysis machine 2 using the buttons 21a, 21b, 21c. In Figure 10 , the buttons 21a, 21b, 21c are shown as differently sized coffee cups, each of which represents a certain amount of liquid. In this way, the patient can report the consumed amount of liquid to the dialysis machine by tapping the cup of the corresponding size.

[0085] For food, a similar representation is conceivable, for example. In this case, the patient can also preferably input which food he has consumed, so that the dialysis treatment can be adjusted for the corresponding consumed electrolytes.
