Description

[0001] Portable peritoneal dialysis device

[0002] The invention relates to a dialysis device, in particular a portable peritoneal dialysis device (PD device), for carrying out a peritoneal dialysis treatment, wherein the dialysis treatment can comprise an automatic, semi-automatic fluid conveyance or based on a gravimetric operating principle.

[0003] The focus is on the flexibility of the patient, which allows him to carry out the therapy treatment in a simple yet comfortable way.

[0004] Increased flexibility offers patients the opportunity to receive treatment virtually anywhere, whether at home, at work, or in a clinic, without sacrificing the comfort and precision of a stationary treatment device. For these exemplary cases, the dialysis machine should be lightweight, manageable, and portable.

[0005] The disadvantage of many dialysis machines is that their complexity, size, and weight make them unsuitable for portable use, or they require additional equipment, such as an IV pole or a support frame for functional setup of the treatment equipment. Therefore, most machines can only be moved within a confined space, such as an apartment, at best. Or they must be disassembled and reassembled for transport, which is a complex process. However, this involves significant transportation costs and time, and is hardly feasible for typically elderly and frail patients without assistance or a carer.

[0006] The present invention is therefore based on the object of providing a dialysis device, preferably a portable peritoneal dialysis device (PD device), which can be compactly folded, rolled up or collapsed for storage, keeping and transport.

[0007] The object is achieved by a portable PD device having the features of claim 1, as well as a portable PD system according to claim 16. Particular embodiments are further specified by the features of the dependent claims.

[0008] The portable PD device includes

[0009] - first fastening means for hanging the PD device

[0010] - second fastening means for attaching a fluid bag to the PD device

[0011] - further second fastening means for attaching a drainage bag to the PD device, wherein the PD device as further components

[0012] - an accounting unit,

[0013] - a data processing unit and - a power supply, and the components can be applied, incorporated or integrated on a flexible or semi-flexible, continuous carrier material of the PD device.

[0014] The portable PD device thus represents a compact unit that includes all essential fastening devices and components for carrying out a dialysis treatment, including automatic, semi-automatic and gravimetric flow control.

[0015] For the use of the portable PD device as an automatic cycler with a fully automatic or semi-automatic fluid control, additional components can optionally be applied, inserted or integrated into the PD device.

[0016] In extended embodiments, the portable PD device may comprise as additional components, for example, an organizer unit, automatic inlet and outlet actuators, one or more sensors, a heating device, a pump system, one or more indicator lights and / or one or more data transmission ports, preferably also wireless.

[0017] For attaching, incorporating or integrating at least one of the following components on the PD device, such as the balancing unit, the automatic inlet and outlet actuators, the organizer unit, the data processing unit, the power supply, the heating device, the pump system, the one or more sensors, the indicator lamp(s) and / or the data transmission port(s), the portable PD device may comprise further second fastening means.

[0018] The first attachment means of the portable PD device allow it to be freely suspended from a door, a wall, a coat hook or coat rack, an IV pole, a counter, a ledge, the ceiling, or similar. The PD device can be attached to any object or element suitable for holding the portable PD device securely and without contact with the ground.

[0019] The first fastening means for hanging the PD device include, for example, hooks, Velcro fasteners, loops, ropes, straps, belts, telescopic rods, cable winches and / or chains.

[0020] To ensure even alignment and load distribution of the PD device, two or three first fastening means, such as hooks, can preferably be provided for suspending and adjusting the height of the portable PD device. For stabilization, mounting means in the form of spacers, rods, strips, tubes, straps, hook-and-loop fasteners, wires, a housing, or similar can be attached or integrated to the top of the portable PD device.

[0021] The first fastening means can preferably be attached to the PD device by gluing, sewing, clipping, welding, screwing and / or hanging.

[0022] For accurate volume balancing, it is essential that the PD device can hang freely and not touch the floor, even under maximum load. Therefore, the first attachment points of the support device can be variable in length, for example, to optimally adjust the height of the PD device to the on-site floor clearance and the patient's position.

[0023] To adjust the height of the PD device, the first fastening means of the PD device can be adjusted, for example, using Velcro fasteners, straps, ropes, or straps with adjustable figure eights, loops, telescopic rods, cable winches, or chains. When chains or straps are used, the length of the receiving device can be individually adjusted using hooks on the individual chain links or pre-punched holes in the straps. In a preferred embodiment, the first fastening means of the portable PD device can be designed as hooks provided with length-adjustable straps. The straps are attached to the receiving device in such a way that their proximal end represents the underside of the first fastening means and are attached to the top of the PD device. The hooks form the upper distal end of the PD device and should be adjusted so that the fluid bags are at a height of approx.150 cm, + / - 10 cm above floor level. This allows for optimal flow rates during inflow and outflow of the patient. The precise alignment of the PD device can be checked and readjusted if necessary using an integrated spirit level.

[0024] The second fastening means serve to accommodate or attach at least one fluid bag with fresh dialysis solution for filling the patient and at least one drainage bag for collecting the used dialysis solution from the patient to the PD device.

[0025] The second fastening means for application, insertion or integration into the PD device include hooks, clips, eyelets, screws, receiving pockets, insertion openings, plug-in or hook-and-loop connections, loops, straps and / or bands.

[0026] The second receiving or fastening means can be attached directly to the carrier material or can be mounted, inserted, or integrated into the flexible or semi-flexible, continuous or one-piece carrier material of the portable PD device via mounting means in the form of spacers, rods, strips, wires, straps, hook-and-loop fasteners, tubes, or similar. The fastening means can also be attached by gluing, sewing, clipping, welding, screwing, and / or hanging.

[0027] The second receiving and fastening means are designed to securely hold the fluid bag(s) filled with fresh dialysis solution, which typically have a capacity of 1-10 l each, preferably 3-6 l, and in particular 1-5 l, and the drainage fluid from the patient in the drainage bag(s). Preferably, 2-3 fluid bags filled with dialysis solution can be provided for a PD treatment. After the PD treatment, the emptied fluid bags can be separated from the tubing set and connected to a new tubing set as drainage bags during the next treatment.

[0028] Furthermore, any means suitable for attaching, inserting, or integrating components of the PD device at their intended positions on a coherent or one-piece carrier material of the PD device can be considered as further second fastening means. For this purpose, the components, such as a balancing unit, automatic actuators, a heating device, a pump system, sensors, an organizer unit, a data processing unit, one or more data transmission ports, indicator lights, bags, etc., can be inserted, inserted, sewn, hung, glued, clipped, welded, and / or screwed.

[0029] It goes without saying that the one or more first fastening means are designed to safely support the maximum weight of the portable PD device in the use state. Use state here means a portable PD device suspended from the first fastening means and prepared for dialysis therapy. The maximum weight of the PD device results primarily from the weight of the PD device including all required and any optionally attached additional components for performing a therapy treatment, the first and second receiving and fastening means, the weight of the filled fluid and / or drainage bags, and a tubing set. The second receiving or fastening means are also designed to safely support the corresponding components.

[0030] A balancing unit is provided to balance the volume of fluid flowing into and out of the patient and to determine the ultrafiltration volume. This balancing unit can be a weighing device or sensors for volume measurement, such as flow sensors.

[0031] A weighing device is preferably mounted in the upper region of the PD device, between the first fastening means(s) of the PD device and the second fastening means for the fluid bag(s). The weighing device can be arranged via a horizontal suspension, for example, on mounting means in the form of a spacer, a rod, a bar, a tube, a housing, or the like. However, it is also conceivable for the weighing device to be attached directly to the first fastening means(s), ideally to one or more hooks of the PD device. However, the weighing device can also be attached at any location on or in the PD device that allows for meaningful weight measurement.

[0032] Load cells, strain gauges, piezo elements, spring carriages, and load cells can be used for the weighing system. The weighing system can determine the total weight of the fluid and drainage bags, or its change before or after each treatment cycle, or it can record the weight continuously. The weight measurement can be used to determine the filling volume and the drainage volume, as well as the ultrafiltration volume. A volume decrease, for example, due to reabsorption of fluid into the patient, can also be derived from the weight data.

[0033] In a preferred embodiment, flow sensors can also be used as a balancing unit. When using flow sensors for volume balancing, they can be mounted, inserted, or integrated into the PD device, preferably into the flexible or semi-flexible, one-piece carrier material. Second mounting and fastening means are also suitable for this purpose, as already described in detail above.

[0034] If the fluid flow, monitored by flow sensors, occurs at low flow rates in the range of 0-250 ml / min, preferably in the range of 0-180 ml / min, a weighing device could be omitted in these cases. Using a weighing device and at least one flow sensor also allows redundant monitoring of the functionality of the weighing device, or vice versa.

[0035] The data processing unit of the portable PD device includes a transmitting and receiving unit.

[0036] The data processing unit is configured to control electronic processes selected from the group of controlling the balancing unit, the automatic inlet and outlet actuators, the heating device, the pump system, the control lights, the sensor(s), the recording, transmission and storage of measurement data, wherein the data processing unit is in communication connection with a display and control system for carrying out and adapting therapy treatments, for displaying the treatment results, for documentation or service purposes and / or for other bi-directional data transfer between the data processing unit and the display and control system, in particular a mobile terminal.

[0037] The mobile device can be a laptop or similar, preferably a tablet or smartphone.

[0038] The PD device includes an interface for wired and wireless communication with a display and control system, particularly a mobile device. Data can be transmitted wirelessly via Bluetooth, Wi-Fi, ZigBee, NFC, Wibree, or WiMAX.

[0039] The mobile device also allows the patient to identify and / or register for treatment on the PD device using facial, iris, voice, or fingerprint recognition, a PIN code, or other methods. The mobile device includes an application (app) that allows the patient or user to control the entire therapy session via the mobile device. The app also offers the option of guiding the patient through the treatment process and providing training instructions or troubleshooting assistance in the form of a video clip, written information on the mobile device's display, or as voice output. The patient can also view their treatment status and progress at any time via the app, as all data collected via the mobile device or transmitted via the data processing unit is logged and saved.Based on the measured and recorded data, the app can adjust the treatment prescription or provide customized therapy suggestions to the user. Furthermore, the patient can select their preferred language from a variety of languages ​​via a selection window in the app and can also operate the PD device largely via voice control. Data can also be forwarded to a dialysis center, a physician, nursing staff, etc. via the mobile device.

[0040] The mobile device can also record warning, alarm, and error messages, as well as status information from the PD device, and forward them to technical service and the attending dialysis center. This allows operating or technical errors to be recorded and analyzed, and subsequent remedial action in the form of training or repairs to be offered. New, improved software can also be remotely uploaded to the PD device's data processing unit via the mobile device. After successful transmission of treatment and technical data via the mobile device to a higher-level information and data processing system in the attending dialysis center or to technical customer service, the data can be automatically deleted from the PD device's data processing unit.

[0041] Using a camera or reading device on the mobile device, this identification means, such as a barcode, QR code, or similar, can be read on the consumables (e.g., solution bag, tubing set, disinfection cap) for a therapy treatment. This makes it possible, among other things, to determine which solution type and bag volume the patient has selected for their treatment and compare this with the prescription. If the selected solutions do not match the prescription, an error message can be issued in the form of an acoustic, visual, or tactile alarm. This contributes to patient safety. At the same time, the shelf life of the consumables used can be checked. Furthermore, the consumption of the individual materials (e.g., solution bag, tubing set, disinfection cap) is documented and can be used for logistical purposes, e.g.Inventory management and / or reordering.

[0042] Using the camera on their mobile device, the patient can also take an image of their abdominal catheter. The app can be used to analyze the image to alert the patient early on to possible inflammatory processes at the catheter entry site, or to document and remotely analyze the healing process. In addition to the image analysis results, measurements of fluid properties from the optional sensors of the PD device, such as color, turbidity, white blood cell concentration, or even the temperature of the drainage fluid, can be used to diagnose possible peritonitis.

[0043] However, this list of the app's functionalities should not be considered as an exhaustive list.

[0044] The components of the portable PD device that require power are primarily the balancing device and the data processing unit. Furthermore, indicator lights for displaying the operating status of the PD device or the electronic components, as well as data transmission ports, can also be connected to a power supply. Suitable data transmission ports include USB ports or similar devices, for example, for connecting additional storage or communication media. The electronic components of the PD device are powered by a power supply, preferably selected from the group consisting of a power cable, power pack, one or more rechargeable batteries, or a USB port. A USB port on the PD device can also be used to supply power to the electronic components or charge the batteries.

[0045] Additional components can be optionally attached or inserted into the portable PD device. Therefore, the PD device is designed so that optional components can be added as needed.

[0046] In order to be able to supply optional electronic components of the PD device with energy in a simple and quick way, the PD device can include plug connections for connecting the automatic inlet and outlet actuators,

[0047] - the organizer unit,

[0048] - the heating device,

[0049] - the pump system and / or

[0050] - the sensor(s), to the power supply.

[0051] Preferably, flexible electrical supply cables for the mains connection and for the plug connections of the connected electronic components can be mounted on or within the PD device. They are preferably enclosed within the PD device to protect them from external damage or tampering.

[0052] The portable PD device can include additional optional components, as described above. Another optional component is an organizer or a holder for an organizer. The organizer is used to accommodate a tubing system, enabling low-contamination connection and disconnection of the patient-side connector to a tubing set. After treatment, the tubing set can be disconnected from the patient connection and disposed of, while the organizer and holder are reusable.

[0053] Preferably, the portable PD device has a holder onto which the organizer can be attached or slid. The organizer and holder then form an organizer unit.

[0054] The organizer unit or the holder can also be attached to, in, or on the flexible or semi-flexible, one-piece or continuous carrier material of the PD assembly using the second receiving and fastening means and in the same manner as described above. The organizer unit or just the holder can be attached to the portable PD device in a foldable or pivotable manner, thus ensuring good usability and allowing the PD device to be easily and compactly folded, rolled up, or folded after use. Furthermore, a locking mechanism can be provided to hold the organizer unit in a secure position while inserting the tubing set.

[0055] Alternatively, the organizer can be a separate assembly, which can be equipped with automatic inlet and outlet actuators and / or other sensors, for example, which can then also be optionally connected to the power supply.

[0056] If flow sensors are used as a balancing unit, these can also be added as optional components.

[0057] As a further optional component, the portable PD device can include automatic inlet and outlet actuators.

[0058] In this context, actuators are understood to be inlet and outlet valves or inlet and outlet clamps, such as hose or roller clamps, electromagnetic valves, or clamps. The actuators can be operated both manually and automatically.

[0059] When using automatic inlet and outlet actuators, these can be permanently connected to the portable PD device by means of second receiving or fastening means, or they can be inserted or inserted via insertion openings or receiving pockets on the portable PD arrangement and connected to the power supply.

[0060] An inlet actuator is provided to control the filling of the patient with dialysis fluid. Several fluid bags can be linked together via a Y-connector of a tubing set and fed to the patient via an inlet actuator. However, with some therapy prescriptions, a final inlet from a so-called "last bag" is provided before the patient is disconnected. The contents of this bag remain in the patient until the next therapy treatment and are connected to the tubing set via a second Y-connector. Since the last bag usually has a different concentration of the osmotic agent than the other fluid bags, an additional inlet actuator is useful for this optional treatment step. In this way, all fluid bags can be connected at the start of treatment, so that treatment can be carried out during the night without further interruption for the patient.Manual operation of the inlet and outlet actuators, for example, using simple hose clamps, is also included. An outlet actuator can be used to remove the drainage fluid from the patient. The actuators can be equipped with indicator lights to indicate their function.

[0061] To determine a wide variety of fluid and / or patient parameters, the PD device can comprise one or more sensors for recording and transmitting measurement data. These primarily involve weight and / or volume measurements from the balancing unit. Furthermore, the temperature of the fresh solutions flowing from the fluid bag or the used solutions flowing into the drainage bag can also be recorded. It is also conceivable, however, that additional sensors are attached to or in the PD device, which can provide measurements regarding fluid properties, such as color, turbidity, or the concentration of white blood cells. These measurements can provide an early indication of possible peritonitis. Furthermore, the content of the osmotic agent, such as glucose, and / or the conductivity in the fresh dialysis solution as well as in the drainage fluid can be determined. A pressure sensor can also be provided, which allows, for example,to determine the intraperitoneal pressure in the patient. Furthermore, the PD device can have one or more flow sensors to determine the flow rate of the fresh dialysis fluid and the drainage fluid. Non-invasive sensors are preferably used as sensors. The measured values ​​can be sent to the data processing unit and transmitted to the mobile device for further processing and storage, or directly to the mobile device.

[0062] In a preferred embodiment, the organizer or organizer unit can represent a separate assembly that is attached to or integrated into the PD device and has extended functionalities. For example, automatic inlet and outlet actuators can be arranged in the organizer. Furthermore, sensors can also be provided in the organizer to determine fluid properties in the dialysis fluid or drainage fluid or to determine the intraperitoneal pressure in the patient's peritoneum. The sensors and the automatic actuators can be controlled by the data processing unit. The organizer can further comprise sensors for determining a flow rate for volume balancing. The measured values ​​can also be sent to the data processing unit and transmitted to a display and control system, preferably to the mobile device, for further processing and storage.

[0063] To heat the dialysis solution to a comfortable temperature for the patient, the PD device can, as listed above, have additional second means for accommodating or attaching a heating device. A heating or warming mat can be provided as a heat source. This can be permanently integrated in the area of ​​the fluid bags in the PD device or attached or inserted as an optional component on the PD device as needed. For this purpose, receiving pockets or insertion openings can be provided on the PD device to allow the fluid bags to be inserted or pushed in from above or from the side and connected to the power supply of the PD device via a plug connection and its corresponding supply lines.

[0064] The second means of fastening or holding components mentioned above are not to be understood as exhaustive.

[0065] Instead of a heating mat, heating rods or heating wires can also be fixed to or in the receiving device. The heating device can be designed to enclose the fluid bag(s) as completely as possible. To minimize heat loss during the warm-up phase of the dialysis fluid, thermal insulation can be provided on the side(s) of the heating device facing away from the fluid bags. In an alternative embodiment, the heating device can also comprise an infrared heat source.

[0066] The heating device also has a heating control system. To measure the temperature of the dialysis fluid in the fluid bag(s), at least one temperature sensor can be provided. This sensor is connected to the heating device in such a way that it can measure and control the temperature of the fluid at the bag surface or at the tubing at the bag outlet. Furthermore, the fluid temperature can also be measured by a temperature sensor on the organizer on the tubing and used to control the heating system.

[0067] For use of the portable PD device as an automatic or semi-automatic cycler, a pump system can be attached to or integrated into the portable PD device as an optional component. Second fastening means, as described above, can also be provided for this purpose. In this way, it is possible to control the fluid flow into and out of the patient fully automatically or semi-automatically, for example, by gravimetrically controlling the fluid inlet and the fluid outlet into the drainage bag(s) by at least one pump. Here, too, the pump system is controlled and data is transferred via the data processing unit.Alternatively, the optional pump system can also be used to pump fluid samples from the drainage bag(s) into one or more separate sampling containers or to dispose of the entire volume from the drainage bag into a drain via a drainage tube after treatment.

[0068] Tubing reel or syringe pumps are particularly suitable for the portable PD device according to the invention. However, other types of pumps are also conceivable.

[0069] The indicator lights can serve as individual components to indicate the operating status of the PD device or be part of the electronic components. The PD device or the electronic components can comprise one or more indicator lights.

[0070] To increase patient comfort and mobility, the PD device should be as lightweight, manageable, and portable as possible. Furthermore, high hygiene standards must be maintained in medical applications, so the materials should be easy to clean and disinfect. The portable PD device is preferably made of a durable, UV-resistant, antibacterial, dirt-repellent, moisture-resistant, and / or air- and gas-tight carrier material.

[0071] For the production of the PD device, carrier materials made of PVC, foam, polyester, polyamide, polypropylene, polyurethane, polyethylene, silicone, nylon, rubber, glass fiber, carbon fiber, metals or combinations of these materials are therefore included.

[0072] The carrier material of the portable PD device can be made entirely of one of these materials or a combination of the materials. The carrier material can be flexible or semi-flexible and continuous in the form of a fabric or film, a mat, or an inflatable cover. Alternatively, a mat, an inflatable cover, a semi-flexible frame, a semi-flexible mesh, or a mounting device can be covered on one or both sides or completely covered with at least one layer of the carrier material.

[0073] Flexible or semi-flexible means that the carrier material can be folded, folded or rolled up without undergoing elastic deformation.

[0074] Some embodiments regarding the design of the portable PD device are described in more detail below.

[0075] In a first embodiment, the carrier material of the portable PD device can be embodied as a fabric or film. However, the carrier material of the portable PD device can also comprise two or more flexible fabric or film layers. These can be sewn, glued, welded, or otherwise connected to one another.

[0076] When using only one layer of the carrier material, first and second receiving and fastening means for suspending the PD device, for receiving or inserting bags, the balancing unit, the organizer unit, the data processing unit, the power supply including the electrical supply lines to the plug connections of the current-collecting components, etc. can be attached directly to the flexible, one-piece or continuous carrier material or connected to the flexible, one-piece carrier material.

[0077] For optional components, as described above, additional second receiving and fastening means can be provided on or in the flexible, one-piece or continuous carrier material of the portable PD device. "One-piece or continuous" means that the carrier material represents a continuous area onto which the first and / or second fastening means are applied, inserted, or integrated. The terms "one-piece" and "continuous" are to be used synonymously in this context.

[0078] Since the fabric or film layers of the one-piece or continuous carrier material are primarily flexible, mounting means, for example in the form of rods, strips, spacers, wires, spirals or tubes or a housing, can be applied to the film or fabric or incorporated between at least two film or fabric layers in order to increase the stability of the portable PD device in use.

[0079] Preferably, gaps are provided between the mounting means so that the portable PD device can be easily folded, collapsed, or rolled up. The mounting means can be attached horizontally or vertically with respect to the first fastening means on the one-piece or continuous carrier material or between at least two layers of the carrier material. It would also be conceivable for the mounting means to run diagonally with respect to the first fastening means. The mounting means can preferably be arranged continuously from one side of the portable PD device to the opposite side. The first and second receiving and fastening means can be attached to the carrier material or the carrier material and the mounting means in such a way that they can be inserted, inserted, sewn, hung, glued, clipped, welded, and / or screwed.

[0080] The at least one fabric or film layer as a one-piece carrier material can, for example, be applied to a semi-flexible frame or a semi-flexible mesh. However, it is also possible to insert the semi-flexible frame or the semi-flexible mesh between two or more fabric or film layers. The fabric or film layers can be sewn, glued, welded, or otherwise connected to each other and completely encompass the frame or mesh.

[0081] A semi-flexible frame or mesh is understood to have a certain degree of dimensional stability while still being deformable. Therefore, the frame or mesh is preferably made of flexible plastic or metal wires or plastic or metal tubes. In a particularly preferred embodiment, the plastic or metal wires can be spiral-shaped. This shape gives the portable PD device high flexibility when rolled up or folded for transport and storage purposes, as well as good dimensional stability during use.

[0082] The semi-flexible frame or the semi-flexible mesh can be designed such that mounting means are or can be integrated into the frame or the mesh for attaching the first and second receiving and fastening means.

[0083] For such purposes, materials made of glass or carbon fiber are particularly suitable for the frame, the mesh or even the mounting materials.

[0084] In a second embodiment, the one-piece carrier material of the portable PD device can be designed in the form of a semi-flexible mat. In particular, the mat can be designed like a yoga mat, which gives the portable PD device a certain degree of dimensional stability, but is still flexible enough to be folded, rolled up, or folded. The mat can be provided with notches or cuts so that it can be rolled up, folded, or folded more easily. The notches or cuts can be arranged vertically or horizontally with respect to the first fastening means. The mat can be covered on only one side with the one-piece carrier material made of at least one film or fabric layer of the aforementioned materials. However, it can also be covered on both sides or over its entire surface with at least one fabric or film layer of the carrier material.As described above, the first and / or second fastening means can be applied, incorporated or integrated onto the carrier material of the portable PD device.

[0085] However, the first and second fastening means can also be applied directly to the mat or connected to the carrier means without further covering.

[0086] In a third embodiment, the portable PD device differs only in that the coherent carrier material can be in the form of an inflatable shell made of an air- or gas-impermeable carrier material, such as PVC, rubber, or mixtures thereof. The inflatable shell can have a valve for inflation, similar to an air mattress or inflatable sleeping pad, or it can be self-inflating. An air pump can be provided as an aid for filling the inflatable pad with air. An inflatable shell or pad offers the advantage of maintaining high dimensional stability when inflated and ready for use, and the portable PD device can be easily and conveniently equipped and dismantled with bags, a hose set, and the necessary electronic components for therapy treatment.Outside of therapy times, the air can be released from the inflatable cover or mat and can be quickly and space-savingly folded, folded or rolled up.

[0087] The advantage of a semi-flexible carrier material in the form of a mat or inflatable covers is that they already ensure sufficient dimensional stability of the PD device in use.

[0088] To increase the stability of the PD device, a bag holder can be provided in all described embodiments to accommodate the drainage bags. For this purpose, the carrier material of the portable PD device can be folded over at the bottom, rolled up, and attached to the sides of the portable PD device, for example, with straps, hooks, Velcro fasteners, or similar fastening devices. Alternatively, the bag holder can already be integrated into the portable PD device in the form of a groove.

[0089] In a fourth embodiment, the one-piece carrier material of the portable PD device can be semi-flexible and composed of several interconnected compartments. For example, the individual compartments can be divided into different regions, such as a first, upper region, which can comprise, for example, the first fastening means including the weighing device, the data processing unit, the data transmission port(s), and the fastening means for the fluid bags; a middle region, which can comprise the inlet and outlet actuators, the organizer unit, sensors, etc.; and a lower region, which can accommodate the drainage bags. The power supply and the connecting lines to the individual electronic components extend over at least two compartments.The individual compartments can be designed as separate compartments that can be connected to form a compact carrying bag using zippers after treatment.

[0090] What all embodiments of the PD device have in common is that the PD device can be folded, rolled up or folded quickly and in a space-saving manner for transport, storage or keeping.

[0091] In all described embodiments, the portable PD device can be fixed in its folded, rolled or wrapped state by a zipper, elastic band, cord, Velcro, hook, clip, snap fasteners, in a bag or the like.

[0092] However, the PD device 1 according to the invention is not limited to the embodiments described above, but also includes combinations of the embodiments.

[0093] In all cases, the material and construction of the portable PD device are selected so that it has sufficient stability during use or when rolled out or unfolded, but is still flexible enough to be rolled up, folded or collapsed after use for storage or transport purposes.

[0094] Due to its low material requirements, the portable PD device is very lightweight, making it ideal for transport and space-saving storage. When folded, rolled up, or folded, the electronic components can also be protected from mechanical damage.

[0095] Since the portable PD device requires very little material and the electronic components are limited to the essential components or can be optionally coupled as needed, the portable PD device is very cost-effective to manufacture.

[0096] The present invention further relates to a portable PD system comprising at least one fluid bag and at least one drainage bag, as well as a tube set which can connect at least one fluid bag and drainage bag to each other and can be connected to a patient connector.

[0097] The present invention will now be described in more detail with reference to embodiments and the drawings.

Mounting means 18, such as strips, rods, wires, tubes, spacers, or the like, can be provided as second fastening means 3, which can be attached to, inserted into, or integrated into the portable PD device 1. The fastening means 3 can also be designed as a housing, which can, for example, accommodate the weighing device 6a. The weighing device 6a is ideally located above the second fastening means 3. The weighing device 6a can also be attached directly to the first fastening means 2 of the portable PD device 1 or at any location on or in the PD device 1 that allows for meaningful weight measurement.

[0129] Sensors 13 in the form of flow sensors 6b can also be used as a balancing unit. When using flow sensors 6b for volume balancing, they can be mounted, inserted, or integrated into the PD device 1, preferably into the flexible or semi-flexible, one-piece carrier material 10. Second receiving and fastening means 3 are also suitable for this purpose, as already described in detail above.

[0130] The portable PD device 1 comprises, as a further component, an organizer 7 or a holder 7a for an organizer 7. The organizer 7 serves to accommodate a hose system 19 (see Figs. 4, 6). The portable PD device 1 preferably has a holder 7a onto which the organizer 7 can be plugged or slid. The organizer 7 and holder 7a then together form an organizer unit 7, 7a. After treatment, the hose set 19 can be detached from the patient connection 20 and disposed of, while the organizer unit 7, 7a can be reused.

[0131] The organizer unit 7, 7a or the holder 7a can also be attached to, in, or on the flexible or semi-flexible, one-piece carrier material 10 of the PD device 1 by means of the second receiving and fastening means 3 by gluing, sewing, clipping, welding, screwing, and / or hanging. The organizer unit 7, 7a or just the holder 7a can be attached to the portable PD device 1 in a foldable or pivotable manner in order to allow the PD device 1 to be easily and compactly folded, rolled up, or folded after use. Furthermore, a locking mechanism can be provided that holds the organizer unit 7, 7a in a secure position during the insertion of the tube set 19. The portable PD device 1 further comprises a data processing unit 8 with a transmitting and receiving unit 22.The data processing unit 8 is configured to control electronic processes selected from the group of controlling the balancing unit 6a, 6b, the automatic inlet and outlet actuators 11, 11a, 12, the heating device 14, the pump system 15, the control lights 16, the sensor(s) 13, the acquisition, transmission and storage of measurement data, wherein the data processing unit 8 is in communication connection with a display and control system for carrying out and adapting therapy treatments, for volume balancing, for documentation purposes and / or for data transfer between the data processing unit 8 and the display and control system, in particular a mobile terminal 21.

[0132] The mobile terminal 21 can be a laptop or similar device, preferably a tablet or smartphone. The portable PD device 1 can include an interface for communication between the data processing unit 8 and the mobile terminal 21, which can be either wired or wireless.

[0133] The mobile device 21 includes an application (app) that allows the patient or user, among other things, to manage the entire therapy treatment via the mobile device 21, view the treatment status and progress, receive and forward data, record and save data, adjust the treatment prescription, or provide the user with customized therapy suggestions. The data can also be forwarded to third parties via the mobile device 21, for example.

[0134] The PD device 1 may further comprise one or more data transmission ports 17, for example, to connect additional storage or communication media.

[0135] The power supply of the electronic components of the PD device 1 is provided by a power supply 9, which is selected from the group of a power cable, power supply, one or more rechargeable batteries or a USB port 17. By means of a USB port 17 on the PD device 1, the electronic components can also be supplied with power or the batteries can be charged.

[0136] The components of the portable PD device 1 that require power are primarily the balancing device 6a, 6b and the data processing unit 8. Furthermore, indicator lights 16 for indicating the operating status of the PD device 1 or the electronic components, as well as data transmission ports 17, can be connected to a power supply 9. USB ports are suitable as data transmission ports 17.

[0137] Additional components can be added, inserted or integrated as optional components on the portable PD device 1 as required.

[0138] In order to be able to supply the optional components with energy in a simple and quick way, the PD device 1 can comprise plug connections 23, for example for connecting

[0139] - the automatic inlet and outlet actuators 11 / 11a, 12,

[0140] - the organizer unit 7 / 7 a

[0141] - the heating device 14,

[0142] - the pump system 15 and / or

[0143] - the sensor(s) 13, to the power supply 9.

[0144] If flow sensors 6b are used as a balancing unit or for fluid flow monitoring, they can also be connected to the power supply 9 as an optional component. If the organizer 7 is equipped as a separate assembly with automatic inlet and outlet actuators 11, 11a, 12 or other sensors 13, etc., this can also be connected to the power supply 9 as an optional component.

[0145] Electrical supply lines 24 for the mains connection and for the plug connections 23 of the connected electronic components can be mounted on or in the PD device, as mentioned several times above. Preferably, they are enclosed by the PD device 1 and / or flexible electrical supply lines 24 are used, which tolerate frequent rolling, folding, or folding well.

[0146] The embodiments of Fig. 1, 4 and 6 show automatic inlet and outlet actuators 11, 11a, 12, which can be fixedly connected to the portable PD device 1 by means of second receiving or fastening means 3 or can be inserted or inserted via insertion openings or receiving pockets on the portable PD device. For this purpose, second receiving or fastening means 3 can be provided in order to apply, insert or integrate the actuators on the PD device 1, preferably on the flexible or semi-flexible, one-piece carrier material 10 of the PD device 1. The actuators can also be part of a further assembly of the PD device 1, for example an organizer 7.

[0147] An inlet actuator 11 is provided for filling the patient with dialysis fluid. Several fluid bags 4 can be connected via a Y-connector of a tubing set 19. However, some therapy prescriptions provide for a final inlet from a so-called "last bag" at the end of the treatment, which can be connected to another inlet actuator 11a via a second Y-connector in the tubing set 19. The drainage fluid can be removed from the patient using an outlet actuator 12. The actuators can be equipped with indicator lights 16 to indicate their function.

[0148] To determine various fluid and patient parameters, the PD device 1 can comprise one or more sensors 13. The sensors primarily measure weight and / or volume values ​​from the balancing unit 6a, 6b. Furthermore, the temperature of the fresh or used solutions in the fluid bags 4 and drainage bags 5 can also be recorded. For this purpose, the sensor(s) 13 can be arranged in the area of ​​the heating device and / or on the organizer for non-invasive temperature measurement on the surface of the fluid bags 4 or on the fluid or drainage line of the tubing set 19. However, sensors 13 can also be used, for example, to determine the color, turbidity, white blood cell concentration, osmotic agent content, and / or conductivity in the fresh dialysis solution as well as in the drainage fluid. A pressure sensor can be used to determine the intraperitoneal pressure in the patient.Furthermore, the PD device 1 can have one or more flow sensors 6b to determine the flow rate of the fresh dialysis fluid and the drainage fluid. The measured values ​​can be sent to the data processing unit 8 and transmitted to the display and control unit, preferably to the mobile terminal 21, for further processing and storage. The sensors 13 can be connected directly to the portable PD device 1 by means of second receiving or fastening means 3 or can be part of an assembly.

[0149] In a preferred embodiment, the organizer 7 or the organizer unit 7, 7a can represent a separate assembly with extended functionalities. For example, automatic inlet and outlet actuators 11, 11a, 12 or sensors 13 can be provided in the organizer 7 for determining fluid properties in the dialysis fluid or the drainage fluid and / or patient parameters. The sensors 13 and the automatic actuators 11, 11a, 12 can be controlled by the data processing unit 8.The measured values, such as color, turbidity, flow rate, fluid pressure, white blood cell concentration, concentration of the components of the dialysis solution, temperatures and conductivity of the fresh and used dialysis fluid, and intraperitoneal pressure in the patient, can also be sent to the data processing unit 8 and transmitted to the display and control system, in particular to the mobile terminal 21, for further processing and storage.

[0150] To heat the dialysis solution, a heating device 14 can be provided as a heat source in the form of a heating or warming mat. This can be permanently integrated in the area of ​​the fluid bags 4 in the PD device 1. However, the heating mat can also be attached to or inserted into the PD device 1 as needed. Alternatively, receiving pockets or insertion openings can be provided into which the fluid bags 4 can be inserted from above or from the side. Instead of a heating mat, heating rods or heating wires can also be fixed to or in the PD device 1. The heating device 14 can be designed to enclose the fluid bag(s) 4 as completely as possible. To minimize heat loss during the warm-up phase of the dialysis solution in the fluid bags 4, thermal insulation can be provided on the side(s) of the heating device 14 facing away from the fluid bags.In an alternative embodiment, the heating device 14 may also comprise an infrared heating source.

[0151] The heating device 14 also has a heating control system. To detect the temperature of the fluid in the fluid bags 4, at least one temperature sensor can be provided, which is connected to the heating device 14 in such a way as to measure and control the temperature of the fluid at the fluid bag surface 4 or at the hose line 19 at the bag outlet.

[0152] The heating device 14 can be permanently integrated into the PD device 1 by means of second receiving or fastening means 3 or, as required, can be connected as an optional component to the power supply 9 of the PD device 1 via a plug connection 23 and its corresponding electrical supply line 24.

[0153] For use of the portable PD device 1 for automatic or semi-automatic fluid delivery, a pump system 15 can be attached to or integrated into the portable PD device 1 as an optional component. Second fastening means 3, as already described above, can be provided for this purpose. In this way, it is possible to control the fluid flow into and out of the patient fully automatically or semi-automatically. Here, too, the pump system 15 and the data transfer are controlled by the data processing unit 8. Alternatively, the pump system 15 can also be used to take fluid samples from the drainage bag(s) 5 into separate sampling containers or to empty the drainage bag(s) 5. Peristaltic or syringe pumps are particularly suitable for the portable PD device 1 according to the invention. However, other types of pumps are also conceivable.

[0154] In order to provide a portable PD device 1 that is as universally usable as possible, second receiving and fastening means 2, 3 for receiving and / or securing all required and optional components for a peritoneal dialysis treatment can be provided on, in, or between the continuous flexible or semi-flexible carrier material 10 of the PD device 1. If the optional components are not used, the space provided for receiving or securing the respective optional components can remain free.

[0155] The portable PD device 1 is advantageously made of a UV-resistant, durable, antibacterial, dirt-repellent, moisture-repellent, and / or air- and gas-tight carrier material 10

[0156] For the manufacture of the PD device 1, carrier materials 10 made of PVC, foam, polyester, polyamide, polypropylene, polyurethane, polyethylene, silicone, nylon, rubber, glass fiber, carbon fiber, metals or material combinations thereof are therefore included.

[0157] The portable PD device 1 can be made entirely of one of these materials or of a combination of the materials. The carrier material 10 is flexible or semi-flexible.

[0158] The carrier material 10 can be flexible or semi-flexible and coherent in the form of a fabric or film 25, a mat 26, or an inflatable cover 27. Alternatively, a mat 26, an inflatable cover 26, a semi-flexible frame, a semi-flexible mesh, or mounting means 18 can be covered on one or both sides or completely enclosed by at least one layer of the carrier material 10.

[0159] In a first embodiment, the carrier material 10 of the portable PD device 1 can be designed as a single piece or continuous fabric or film 25. However, the carrier material 10 of the portable PD device 1 can also comprise two or more flexible fabric or film layers 25. These can be sewn, glued, welded, or otherwise connected to one another.

[0160] When using only one layer of the carrier material 10, first and second receiving and fastening means 2, 3 for suspending the PD device 1, for receiving or inserting bags 4, 5, the balancing unit 6a, 6b, the organizer unit 7, 7a, the data processing unit 8, electrical supply lines 24 to the plug connections 23 of the current-collecting components, etc., can be attached or connected directly to the flexible, one-piece or continuous carrier material 10.

[0161] For optional components, as described above, further second receiving and fastening means 3 can be attached to or in the carrier material 10 of the portable PD device 1.

[0162] Since the fabric or film layers 25 of the one-piece carrier material 10 are primarily flexible, mounting means 18, for example in the form of rods, strips, spacers, wires or tubes, can be applied to the film or fabric 25 or incorporated between at least two film or fabric layers in order to increase the stability of the portable PD device 1 in the use state.

[0163] Preferably, gaps are provided between the mounting means 18 so that the portable PD device 1 can be easily folded, collapsed, or rolled up. The mounting means 18 can be attached horizontally or vertically with respect to the first fastening means on the continuous carrier material 10 or between at least two layers of the carrier material 10. It would also be conceivable for the mounting means 18 to run diagonally with respect to the first fastening means. The mounting means 18 can preferably be arranged continuously from one side of the portable PD device 1 to the opposite side. The first and second receiving and fastening means 2, 3 can be attached to the carrier material 10 or the carrier material 10 and the mounting means 18 in such a way that they can be inserted, inserted, sewn, hung, glued, clipped, welded, and / or screwed.

[0164] The at least one fabric or film layer 25 can also be applied as a carrier material 10, for example, in the form of a semi-flexible frame or a semi-flexible mesh. However, it is also possible to insert the semi-flexible frame or the semi-flexible mesh between two or more fabric or film layers 25. The fabric or film layers 25 can be sewn, glued, welded, or otherwise connected to one another and completely encompass the frame or the mesh.

[0165] A semi-flexible frame or semi-flexible mesh is understood to have a certain degree of dimensional stability while still being deformable. Therefore, the frame or mesh is preferably made of flexible plastic or metal wires or plastic or metal tubes. In a particularly preferred embodiment, the plastic or metal wires can be spiral-shaped. This shape gives the portable PD device 1 high flexibility when rolled up or folded for transport and storage purposes, as well as good dimensional stability during use.

[0166] The semi-flexible frame or the semi-flexible mesh can be designed such that mounting means 18 can be integrated into the frame or mesh for attaching the first and second receiving and fastening means 2, 3. For such purposes, materials made of glass or carbon fiber are particularly suitable for the frame, the mesh, or the mounting means 18.

[0167] In a second embodiment, as shown in detail in Fig. 2, the carrier layer 10 of the portable PD device 1 can be designed in the form of a semi-flexible, one-piece mat 26, which imparts a certain dimensional stability to the portable PD device 1, but is still flexible enough to be folded, rolled up, or folded. The mat 26 can be provided with notches or cuts 28 so that it can be rolled up, folded, or folded more easily. The notches or cuts 28 can be arranged vertically or horizontally with respect to the first fastening means 2 of the PD device 1.

[0168] The mat 26, as shown in Fig. 4, can be covered on only one side with the continuous carrier material 10 consisting of at least one film or fabric layer 25. However, it can also be covered on both sides, or completely covered with at least one fabric or film layer 25 of the carrier material 10. The first and second fastening means 2, 3 can then be applied or integrated onto the carrier material 10 of the portable PD arrangement 1, as described above.

[0169] However, the first and second fastening means 2, 3 can also be applied directly to the mat 26 or connected to it without further covering with the carrier means 10.

[0170] Fig. 3 shows a detail of a third embodiment of the portable PD device 1, which differs only in that it can be in the form of an inflatable cover 27 made of a carrier material 10 that is impermeable to air or gas. The inflatable cover 27 can have a valve 31 for inflation or can be self-inflating. An air pump can be provided as an aid for filling the inflatable cover 27 with air. An inflatable cover or mat 27 offers the advantage that it has a high degree of dimensional stability when inflated and ready for use, and the air can be released outside of therapy times so that it can be folded, rolled up or collapsed quickly and in a space-saving manner. The inflatable cover 27 can also be covered or enclosed on one side, both sides or completely by at least one fabric or film layer 25 of the carrier material 10.The first and second receiving and fastening means 2, 3 can be attached directly to the inflatable cover 27 or can be applied or integrated onto the carrier material 10 with which the inflatable mat 26 is covered or covered.

[0171] To increase the stability of the PD device 1, a bag holder 30 can additionally be provided in all described embodiments, which can accommodate the drainage bags. For this purpose, the carrier material 10 of the portable PD device 1 can be folded over in the lower area, rolled up, and attached to the sides of the portable PD device 1, for example, with straps, hooks, Velcro fasteners, or similar fastening means. Alternatively, the bag holder 30 can already be integrated into the portable PD device 1 in the form of a groove.

[0172] In a fourth embodiment, the one-piece carrier material 10 of the portable PD device 1 can be semi-flexible and composed of several interconnected compartments 32, 33, and 34, as shown in Fig. 4. For example, the individual compartments 32, 33, and 34 can be divided into different regions, such as a first, upper region 32, which can comprise, for example, the first fastening means 2 including the balancing unit 6a, 6b, the data processing unit 8, the data transmission port(s) 17, and the second fastening means 3 for the fluid bags 4, a middle region 33, which can comprise, for example, the inlet and outlet actuators 11 / 11a, 12, the organizer unit 7, 7a, sensors 13, etc., and a lower region 34, which can accommodate the drainage bags 5.The power supply 9 and the electrical supply lines 24 to the plug connections 23 of the individual electronic components extend over at least two compartments. The individual compartments can be designed as separate compartments that can be connected via zippers to form a compact carrying case after the therapy treatment.

[0173] In order to optimally adjust the height of the PD device 1 to the patient's position, the PD device 1 can be equipped with length-adjustable elements 35, for example, length-adjustable straps. As shown in the exemplary embodiment in Fig. 4, the first fastening means 2, for example in the form of hooks, can preferably be combined with length-adjustable straps. In a preferred embodiment, the straps are attached to the PD device 1 such that their proximal end can be connected to the underside of the first fastening means 2 and are attached to the top of the PD device 1. The hooks form the upper distal end of the PD device 1 and should be suspended at a height of approximately 150 cm, + / - 10 cm above floor level. (The exact alignment of the first fastening means 2 can be checked and readjusted if necessary using an integrated spirit level 31.)However, the portable PD device 1 also includes all other embodiments that allow height adjustment of the PD device 1.

[0174] What all embodiments of the portable PD device 1 have in common is that the PD arrangement 1 can be quickly and space-savingly folded, folded or rolled up for transport, storage or keeping, as shown in Fig. 5.

[0175] In all described embodiments, the portable PD device 1 can be fixed in its folded, rolled or folded state by means of a zipper, elastic band, cord, Velcro, hook, clip, snap fasteners, in a bag or the like.

[0176] However, the PD device 1 according to the invention is not limited to the embodiments described above, but also includes combinations of the embodiments.

[0177] In all cases, the material and construction of the portable PD device are selected so that it has sufficient stability during use or when rolled out or unfolded, but is still flexible enough to be rolled up, folded or collapsed after use for storage or transport purposes.

[0178] The present invention further relates to a portable PD system 36 comprising - at least one fluid bag 4 and at least one drainage bag

[0179] 5, and a hose set 19, which connects the at least one fluid 4 and

[0180] Drainage bag 5 can be connected to each other and can be connected to a patient connector 20.
