ENERGY GAINING DEVICE

Description

[0001] The invention relates to an energy generation / energy conversion device for an energy storage device, and in particular relates to an energy generation / energy conversion device for an energy storage device with a module for wireless and / or wired charging of the energy storage device using a fluid flow present in a device. State of the art

[0002] Wireless systems, such as battery-powered systems with connectable energy storage devices, such as motor systems, surgical instruments in the medical field, and the like, are increasingly entering the market, resulting in a general trend away from wired systems and toward wireless or so-called stand-alone systems with an energy storage device ("battery"). These energy storage devices must be supplied with electrical energy to ensure the availability of the products they power.

[0003] The disadvantage here is that energy storage-based products and systems, such as motor-equipped handpieces in the medical field, must first be charged before each intended use.

[0004] A conventional solution involves decoupling the handpiece and energy storage unit, and keeping charged, replaceable energy storage units directly at a treatment location, such as an operating room (OR). Sterilized handpieces are then fitted with the energy storage units in the OR. Further disadvantages include the additional handling required, the respective sizes of separate energy storage units, and the like.

[0005] In the coming years, further miniaturization of corresponding systems and products is expected, with smaller energy storage devices (batteries, power cells, and the like) being conceivable. It is already foreseeable that these energy storage devices will be integrated into the handpiece or attached as a smaller system.

[0006] In cases where such systems and / or handpieces must be reprocessed before reuse, as is often the case in the medical field, for example, there is a need to process these systems and / or handpieces, including their energy storage units or batteries, in a washer-disinfector (WD). One objective, therefore, is to transition away from energy storage units located in the operating room to integrated energy storage units. The separate charging of the energy storage units in the operating room inevitably leads to unnecessary or unnecessarily complicated operating procedures and increased or even disruptive effort, along with correspondingly higher costs.

[0007] Documents US 2010 / 121141 A1, KR 2013 0031171 A, and DE 33 20 076 A1 disclose fluid-driven turbines for medical instruments. First, US 2010 / 121141 A1 relates to a surgical cutting endoscope for visualizing and treating a surgical site within a human body. The cutting endoscope utilizes an elongated tubular body adapted to be inserted through body passages so that the distal end is adjacent to the surgical site. A fluid turbine mounted for rotation adjacent to the distal end is driven by fluids pumped through a passage to rotate the turbine. Various cutters and wound debridement tools can be attached to the distal ends so that they are rotated by the turbine.

[0008] Furthermore, KR 2013 0031171 A discloses a water supply system equipped with an LED light source with disinfection and light therapy functions. The system further comprises a housing, a power generator, and an air bubble generator. The power generator generates electricity from the pressure and flow rate of the water flowing in the housing to power the LED light source.

[0009] Furthermore, DE 33 20 076 A1 describes the advancement of medical tubes and probes using nozzle bodies. By incorporating only a few additional technical elements, such as a shaft and disks perforated for fluid, and by inserting nozzles radially relative to the longitudinal axis, such nozzle bodies can be converted into turbines. Brief description of the invention

[0010] The invention is therefore based on the object of providing an energy generation / energy conversion device that enables charging of systems with energy storage devices before use in the operating room and thereby improves the manageability and usability of such systems.

[0011] Furthermore, the invention is intended to enable harvesting and thus charging of energy storage devices in a RDG.

[0012] According to the invention, this object is achieved by a module having the features of claim 1. Advantageous developments of the invention are the subject of the appended subclaims.

[0013] According to a general idea underlying the invention, systems and / or products are to be produced by harvesting electrical energy.

[0014] Energy can be drawn from an existing fluid circuit to enable the systems to be charged before use. At the same time, a data transmission interface is provided through which the charge level can be read, or a function is provided that reports the charge levels of connected systems or products to the outside world.

[0015] A concrete example of this general idea underlying the invention, for example, in the medical field, involves charging (surgical) systems and / or products used there, such as handpieces with integrated or connectable energy storage devices and the like, in a product reprocessing process by "harvesting," i.e., obtaining or generating (electrical) energy in or from an existing fluid circuit, for example, a water circuit, of a washer-disinfector (WD), in order to enable the necessary charging of the systems and / or products prior to use in the operating room. A correspondingly efficient energy harvesting / energy conversion device can be constructed as a module that can be read out via a data transmission interface or that externally reports the charge levels of the connected products.

[0016] In other words, based on the aforementioned concrete example, the underlying general idea includes an energy recovery device or a module for wireless or wired charging of energy storage devices using the prevailing fluid pressure in a fluid flow or fluid circuit already used for other purposes (for example, the water circuit in a washer-disinfector). It is immediately clear that neither the general idea nor the invention are limited to the medical field, and in particular to a fluid circuit of a washer-disinfector and corresponding systems and / or products. The decisive factor in the present invention is that electrical energy is recovered as a waste product from existing energy systems such as fluid flows for cooling / operating / cleaning, etc., which can then be profitably used to charge energy storage devices in surgical instruments.

[0017] Advantages that directly result from the possibility of charging systems and / or products by obtaining energy from a fluid circuit, for example during a reprocessing process in a RDG, include a significant saving in preparation time, reduced handling effort at the site of use or deployment such as an operating room, the immediate usability of systems and products at the site of use or deployment, and the possibility of viewing charging states via a data transmission interface, for example via an application for mobile devices, software on a PC and the like.

[0018] Specifically, the problem is solved by an energy generation / energy conversion device for a rechargeable energy storage device, wherein the energy generation device is adapted to be arranged on / in a fluid line of an existing fluid circuit in a device through which a fluid flows, and the fluid flow in the fluid line primarily serves a predetermined purpose other than energy generation.

[0019] Preferably, the energy generation device is constructed in a modular manner and is arranged to generate electrical energy by means of an energy harvesting process on the basis of the fluid pressure in the existing fluid circuit of the device and to charge the energy storage device with the energy thus generated.

[0020] Further preferably, the energy generation device includes a conversion unit for converting the fluid pressure of the fluid flow or the flow energy of the fluid into a rotational movement, for example of a turbine, and a generator unit for converting the rotational movement into generated electrical energy.

[0021] Preferably, the conversion unit for converting the fluid pressure / flow energy into a rotational movement includes a rotor element with a predetermined geometry, which is rotatably mounted in a housing of the energy generation device and lying in the fluid flow.

[0022] It is advantageous if the predetermined geometry is paddle-wheel-shaped or helical. Alternatively, a so-called spherical turbine is also conceivable, consisting of a sphere with circumferentially spaced pockets cut out along the equator line, which serve as pressure collection troughs for the rotary drive of the sphere. The sphere itself can be centrally penetrated by a rotating shaft, which is rotatably mounted on both sides of the sphere.

[0023] Furthermore, in the energy generation device, the conversion unit for converting the fluid pressure into a rotational movement can preferably be an electric motor which is driven by the fluid flow during a flushing process and operates as a generator, which includes a rotor having a predetermined geometry and is configured to generate electrical current in cooperation with a stator element, by means of which the energy storage device can be charged by means of an induction device for inductive charging of the energy storage device or by means of a charging cable for wired charging of the energy storage device.

[0024] Preferably, the energy generation device includes an electronic control system arranged on a circuit board in a housing of the energy generation device.

[0025] Advantageously, the energy recovery device is configured to detect a fill level of the energy storage device and to open a bypass upon detection of a predetermined (maximum) fill level, wherein the bypass is arranged to guide the fluid flow past the conversion unit in the open state, and wherein in this case the conversion unit is configured to terminate both its rotation and the generation of energy for charging the energy storage device.

[0026] Preferably, the electrical energy generated by the generator unit can be transferred to the energy storage device and / or a product by means of induction via a flexible circuit board comprising an induction line.

[0027] Alternatively, the energy generated by the generator unit can preferably be transferred to the energy storage device via a charging cable.

[0028] Also preferably, the energy generation device comprises the module, a device for determining a state of charge of a connected energy storage device and a data transmission interface via which the module can be read out or communicates the state of charge to the outside.

[0029] A module containing the energy harvesting device can be represented, wherein the module is for use in a processing process for products, systems, and / or instruments with an integrated or connectable, replaceable, and rechargeable energy storage device and is configured to be held or stored in a processing device during the processing process.

Furthermore, an electronic controller for controlling operating sequences can be provided on the module.

[0030] In a practical case, the device is preferably a cleaning / disinfection device (WD) for processing medical instruments, systems and / or products, wherein the medical instruments, systems and / or products comprise at least one handpiece with a rechargeable energy storage device that can be coupled to and / or integrated into the handpiece, wherein the energy storage device is configured as an accumulator or as a power cell and is designed to be processed together with the handpiece in the cleaning / disinfection device.

[0031] Then, further preferred is a washer-disinfector (WD) for processing medical instruments, systems, and / or products, wherein the medical instruments, systems, and / or at least one handpiece comprise a rechargeable energy storage device that can be coupled to and / or integrated into the handpiece, wherein the energy storage device is configured as an accumulator or power cell and is designed to be processed together with the handpiece in the washer-disinfector. In the washer-disinfector, an energy recovery device according to one of the preceding claims is configured to a) be held on a predetermined support or a predetermined sieve basket of the washer-disinfector,or b) as a module integrated into a rinsing rack of the cleaning / disinfection device, comprising an induction device for wirelessly transmitting energy by induction or a charging cable arrangement for wired energy transmission for charging a product connected to the cleaning / disinfection device, or c) as a module integrated into a predetermined mounting of the cleaning / disinfection device, comprising an induction device for wirelessly transmitting energy by induction or a charging cable arrangement for wired energy transmission for charging an instrumentation accommodated in the cleaning / disinfection device and equipped with at least one energy storage device, or a product connected to a hose section of the cleaning / disinfection device.

[0034] In the figures, identical reference numerals designate identical or at least equivalent parts and components. For convenience, redundant descriptions of such parts and components are omitted. Detailed description of preferred embodiments

[0035] Preferred embodiments of an energy recovery device described herein are described below with reference to a conventional washer-disinfector (WD), such as those used in the medical field for reprocessing reusable products, systems, and / or instruments. For cleaning and disinfection, a WD uses a combination of mechanical, thermal, and chemical treatment, similar to that used in a dishwasher. Heated water, optionally enriched with chemicals, is applied under pressure to the objects to be cleaned.It is understood that the invention is in no way limited to the medical field, products, systems and / or instruments used therein, or the arrangement in or use of an RDG, but correspondingly modified configurations and modifications for numerous other and / or other products with integrated or connectable (replaceable) energy storage and devices with a fluid circuit are conceivable and representable.

[0036] Fig. 1 shows a front view and a top view of a schematic representation of a device for illustrating a principle of energy generation using the energy or pressure of a fluid flow in a hose section of a device according to an exemplary embodiment. In the present exemplary embodiment, the device is a known washer-disinfector (WD) as described above.

[0037] In Fig. 1 Reference numeral 2 denotes a hose section or line section of a fluid circuit in the device, for example, a water circuit in the WD. A fluid flow / water flow with a predetermined fluid pressure / water pressure and / or a predetermined flow velocity in the hose section 2 is indicated by black arrows.

[0038] Reference numeral 4 denotes an energy recovery device according to the exemplary embodiment. The energy recovery device 4 has a conversion unit, which is designed as a shaft or a rotor 6 with a predetermined geometry, for example a paddle-wheel-shaped geometry or a helical geometry, and is arranged and configured to convert the longitudinal movement of the fluid flow in the hose section 2 into a rotational movement. The fluid flow or its pressure and / or speed acts on the rotor 6 and sets it in rotation. A generator device 8 is arranged and configured to convert the rotational movement of the rotor 6 into energy, i.e., to generate energy.The generator device 8 is coupled to an electronic controller 10, which can be arranged on a circuit board (not shown) and is configured, among other things, to control at least the energy generation and distribution of the generated energy, as well as its predetermined conversion and discharge from the energy generation device 4. The entire system, as described above, is housed in a fluid-tight housing.

[0039] In practice, energy generation using the energy or pressure of a fluid flow involves a so-called harvesting or "harvesting" of energy. The fluid flow or its water pressure is used to drive a unit (the conversion unit or its rotor 6) that converts the water pressure in the hose section 2 into a rotational movement, for example, by means of a paddle wheel, a worm shaft, or the like. A generator (the generator device 8) is used to convert the rotational movement into energy. An electronic controller 10 is located, for example, on the circuit board. The entire system is housed.

[0040] Fig. 2 shows a schematic representation of a module 100 integrated into a washing rack of the WD in operative connection with an induction device 110 for charging an energy storage device of a product, system, or instrument 120 in an energy generation device according to the exemplary embodiment. A washing rack is understood here as a type of storage comparable to a conventional washing basket in the WD, on or in which parts to be processed can be placed or inserted. The washing rack is in Fig. 2 indicated as a partial background structure.

[0041] The module 100 is configured to be placed on the rinsing rack, whereby brackets or fixing options may be provided. The module 100 has a connection 105 for connecting it to the water circuit of the WD. Arrows in Fig. 2 indicate a flow path of water flowing through module 100 during operation of the WD. As shown in Fig. 2 As shown, water flows into the module 100 at the rear connection 105 and is guided via a conduit 115 (which in this embodiment includes the hose section 2, but can also be rigid at least in part or entirely) to a port section 130. The port section 130 has a plurality of connection ports 135 for products, systems and / or instruments. In this embodiment, for example, three connection ports 135 are provided, and according to Fig. 2 a handpiece 120 as one of a product, system or instrument is held at one of the connection ports 135 in such a way that it can be flowed through by water flowing in via the corresponding connection port 135.

[0042] In the cable routing 115 is also the Fig. 1 The energy recovery device or energy recovery unit 4 shown is arranged in such a way that it is flowed through by water flowing through the line guide 115 and the above-mentioned Fig. 1 This means that during operation of the RDG, water flows through the energy recovery device 4, the rotor 6 rotatably mounted therein rotates, and by means of the rotation, the generator device 8 coupled to the rotor 6 harvests or extracts energy from the water flow, which primarily serves for treatment in the RDG (and thus not primarily for energy generation).

[0043] The generated energy is then converted by the electronic control 10 into, for example, a suitable form and fed to the induction device 110 via a line connection or induction line 140. The induction device 110 may include, for example, a flexible printed circuit board with an induction line as a suitable additional peripheral. As shown in Fig. 2 As shown, the induction device 110 is arranged flatly beneath the connection ports 135 in an area in which energy storage devices (not shown) of products, systems, and / or instruments connected to the connection ports 135 are located when connected. In this way, these energy storage devices can be charged by means of the induction device 135, which is supplied by the energy harvested from the water flow by the energy harvesting device, during the operation of the RDG, i.e., during its reprocessing or cleaning and disinfection operation.

[0044] The energy harvesting device 4 for a rechargeable energy storage device is thus arranged on a fluid line of an existing fluid circuit in a device, through which a fluid flows. The fluid flow in the fluid line primarily serves a predetermined purpose other than energy harvesting. The energy harvesting device is arranged to harvest energy from the fluid flow to charge the rechargeable energy storage device. The module 100 includes the energy harvesting device 4 and an induction device 110, which is powered by energy harvested in the energy harvesting device 4 and is configured to charge energy storage devices located in its induction field while the washer-disinfector (WD) executes its predetermined operating sequence and during which the energy harvesting device 4 harvests energy from the water circuit of the washer-disinfector (WD).In other words, harvested energy is transferred to the products, systems, and / or instruments via induction and thus suitable additional peripherals, such as a flexible circuit board with an induction line. Alternatively, a charging connection via a positive pole connection and thus via a charging cable is also conceivable. The washer-disinfector includes at least one module 100, which is configured to be attached to at least one washing rack of the washer-disinfector and to be connected to the washer-disinfector's water circuit.

[0045] In a modification of the exemplary embodiment described above, it can be provided that products, systems and / or instruments report back to the electronic controller 10 that a predetermined fill level or charge state of their energy storage device has been reached. In this case, the electronic controller 10 can be configured, by means of suitable control, for example of an actuator or valve, to mechanically cause an opening of a bypass device that is arranged and configured to redirect the water flow and direct it past the rotor 6, so that the rotor 6 no longer rotates, as a result of which the generator device 8 no longer generates energy, and thus the charging of the energy storage device is terminated or at least suspended for the duration of the bypass device's opening.

[0046] Fig. 3 shows a schematic representation of a module 100 mounted in a sieve basket in operative connection with an induction device 135 for charging an energy storage device of a product, system or instrument in an energy generation device 4 according to the exemplary embodiment.

[0047] As in Fig. 3 As shown, the module 100 can be Fig. 2 in a modification for charging a (single) product, system, or instrument. In this case, the configuration of the module can be simplified, for example, in that the (single) connection port 135 is installed directly on the energy harvesting device 4. In addition, the induction device 110 can be made correspondingly smaller. It is noted that in Fig. 3 Furthermore, screw connections of the module 100 with the flushing rack or strainer basket for fixing it to or in it are shown.

[0048] It is understood that the Fig. 3 The modification shown is not limited to charging a product, system, or instrument, and that any other products, systems, and / or instruments having an integrated or attachable, removable, and rechargeable energy storage device can be charged in a single configuration of the module 100.

[0049] For example, with a corresponding length, size, and / or routing of the line connection 140 or the induction device 110, for example, routing or positioning it at a relatively farther distance from the energy generation device 4, the energy storage device of a more space-consuming, i.e., larger, product, system, or instrument, which does take up space and therefore requires a certain distance from other components, but as such does not need to be flushed and therefore does not require coupling to a connection port 135, can also be inductively charged. In such a case, the connection port 135 on the energy generation device 4 can be omitted.

[0050] In a further modification of the above embodiment, the larger products, systems and / or instruments both in the above single configuration (with as in Fig. 3 shown a connection port 135 directly on the energy generation device 4) also allows for a module 100 with several connection ports 135, at least one connection for the line connection 140 to the induction device 110 can be designed to be pluggable and connection ports 135 can be mechanically and fluid-tightly closed, for example using an actuator and / or valve which provides a closure device and which is controlled by the electronic control 10, or using a membrane or closure device or the like which opens / closes automatically when a product, system or instrument is coupled / uncoupled.

[0051] In this case, a configuration can be such that when the electronic controller 10 detects the presence of a product, system or instrument and / or an induction device 110 connected to the energy generation device 4, but detects that a corresponding connection port 135 is not occupied, ie when the electronic controller detects that the energy storage device of a product, system or instrument is to be charged, but the product, system or instrument is not to be flushed and has therefore not been connected to the connection port 135, the electronic controller 10 causes the connection port 135 to be closed in a fluid-tight manner and charging energy is conducted to the induction device 135 in order to charge the corresponding energy storage device.

[0052] In the aforementioned configuration, space-consuming products, systems and / or instruments which, due to their size or design, cannot be connected to the at least one connection port 135 present on the module 100 or the one on the energy generation device 4, or which cannot be flushed and therefore cannot be connected to the connection port 135 present on the module 100 or on the energy generation device 4, can be processed with simultaneous charging of their energy storage even if the module 100 and / or the energy generation device 4 has one or more connection ports 135.In other words, a space-consuming product, system, or instrument does not require a specific embodiment (with / without a connection port) of the module 100 and / or the energy harvesting device 4. Rather, any product, system, or instrument can be prepared and charged simultaneously using uniformly constructed modules 100 or energy harvesting devices 4. It is noted that unoccupied connection ports 135 can be closed by default, so that maximum fluid or water pressure is applied to occupied ports.

[0053] Fig. 4 illustrates in a schematic representation the above in connection with Fig. 3 For reasons of simplicity and clarity, the relationships described Fig. 4 redundant reference symbols omitted.

[0054] Fig. 5 shows a schematic representation of a module with charging pads permanently installed in a cleaning / disinfection device in an energy generation device according to an embodiment (stand-alone variant).

[0055] According to the Fig. 5 In the embodiment shown, a module 100 (an energy generation device 4) is permanently installed in a WD and connected to at least one charging pad 160, which can be designed to be permeable to splash water. Products, systems, and / or instruments stored in sieve baskets 165 with integrated or coupled, replaceable energy storage devices can then be inductively charged with or without flushing via the at least one charging pad 160. Likewise, for example, non-flushing individual products 170 with energy storage devices can be connected and charged directly to the energy generation device 4 by means of a (charging) cable 180.

[0056] Fig. 6 shows, as a further modification, a schematic representation of a use of a flushed electric motor 200 installed in a product 120 as a generator for charging an energy storage device (not shown) of the product with energy generated in generator operation in an energy generation device or an energy generation module according to another embodiment. Fig. 7 shows a schematic representation of the use of the electric motor installed in a product as a generator for charging the energy storage device of the product with energy generated in generator mode in an energy generation device according to the other embodiment. According to Fig. 6 and Fig. 7 the energy generation device 4 is, so to speak, relocated into the product, system or instrument or the technical elements already present there are used to generate energy in situ.

[0057] The electric motor 200 is used as a generator during the rinsing process in the WD. A rotor 210 of the electric motor 200, which is designed with a suitable geometry (for example, helical wave-shaped), generates electrical current in cooperation with a stator of the electric motor. The generated electrical current is used to charge the energy storage device via an induction device 110, alternatively via a charging cable (not shown). If necessary, an electronic control 10 is used. Otherwise, the Fig. 7 shown module 100 with the exception of the energy generation device 4, whose function in this embodiment is taken over by the electric motor 200 which is flushed and operated in generator mode during the flushing, the in Fig. 2 shown module 100.

[0058] As described above, an energy harvesting device for a rechargeable energy storage device is arranged on a fluid line of an existing fluid circuit through which a fluid flows in a device. The fluid flow in the fluid line primarily serves a predetermined purpose other than energy harvesting. The energy harvesting device is arranged to harvest energy from the kinetic energy of the fluid flow to charge the rechargeable energy storage device. A module that can be inserted into the device can contain the energy harvesting device.In practice, the device can be a washer-disinfector (WD) for processing medical instruments, systems and / or products, wherein the medical instruments, systems and / or products comprise at least one handpiece with a rechargeable energy storage device that can be coupled to and / or integrated into the handpiece, wherein the energy storage device is configured as an accumulator or as a power cell and is designed to be processed together with the handpiece in the washer-disinfector.

[0059] It is understood that the invention is not limited to the embodiment described above, but changes, modifications, combinations and equivalent arrangements within the scope of protection defined in the claims are also encompassed by the invention, such changes, modifications, combinations and equivalent arrangements being readily apparent to a person skilled in the art.
