Description

Technical field

[0001] The invention relates to an arrangement for performing a bladder irrigation on a person, comprising a reservoir filled with a rinsing fluid, a rinsing line fluidically connected to the reservoir which can be connected to a bladder catheter, and a drainage line connectable to the bladder catheter. State of the art

[0002] In urology, continuous bladder irrigation (CBE) is an important standard procedure whose main goal is to prevent the formation or retention of blood clots within the body and subsequent illness or complications. The purpose of continuous bladder irrigation is to maintain a very low blood concentration in the lower urinary tract. Technically, CBE ensures the continuous flushing of blood, urine, and tissue components using fresh irrigation fluid, typically saline or Ringer's solution, thus preventing the formation of blood clots. Although this type of irrigation may seem straightforward, CBE is of great importance in clinical practice. Improperly performed CBE can cause pain and bladder spasms, potentially lead to additional unwanted bleeding, and even become life-threatening.

[0003] These and other potential complications are partly due to the increased pressure caused by a high inflow rate. Therefore, the irrigation fluid flow rate must be set high enough to adequately flush out the blood, while simultaneously being kept as low as possible to avoid pressure-related complications. Since the amount of postoperative bleeding cannot be controlled, the optimal flow rate must be readjusted over time. Far more common are complications resulting from inadequate monitoring of the urinary tract. An unnoticed interruption of the irrigation, such as an empty irrigation bag or a kink in the inlet tubing, can lead to clot formation, which must be removed in a secondary procedure. An unnoticed break in the drainage tubing or an overflow of the waste bag leads to a backup of irrigation fluid into the bladder.An unnoticed increase in the amount of blood in the rinsing fluid can lead to significant blood loss in the patient.

[0004] Therefore, bladder irrigation requires comprehensive and continuous monitoring and adjustment by medical personnel, which represents a high demand for staff and a significant workload. However, this can be mitigated to some extent by the use of sensor-supported monitoring systems. As an example of such monitoring systems, automated monitoring of bladder irrigation by optical detection of bleeding, for example with a camera module or similar device along a section of tubing leading from the patient, should be mentioned.

[0006] In addition to a considerable need for medical personnel, which represents an economically relevant cost factor, the significant consumption of rinsing fluid is another relevant cost factor, especially in urological clinics and hospitals. Description of the invention

[0007] The invention is based on the objective of further developing an arrangement for performing bladder irrigation on a person, comprising a reservoir filled with a rinsing fluid, a rinsing line fluidically connected to the reservoir and connectable to a bladder catheter, and a drainage line connectable to the bladder catheter, in such a way as to significantly reduce the consumption of rinsing fluid during bladder irrigation.

[0008] The problem underlying the invention is solved by an arrangement according to claim 1. Advantageously further developing the inventive concept are the subject of the dependent claims and the further description, in particular with reference to the illustrated embodiment.

[0009] According to the solution, the arrangement for performing bladder irrigation on a person with a reservoir filled with a rinsing fluid, a rinsing line fluidically connected to the reservoir which can be connected to a bladder catheter, and a drainage line connectable to the bladder catheter, is characterized in that the drainage line is fluidically connected to the reservoir via a filter arrangement.

[0010] The idea underlying the invention departs from the previous practice of disposing of the rinsing fluid used after a single bladder irrigation, not least for hygiene reasons. Instead, the proposed arrangement utilizes the rinsing fluid used after flowing through and rinsing the bladder as a reusable resource, so that the used rinsing fluid is returned to the storage container after suitable purification.

[0011] Irrigation fluid, which flows from the reservoir into the bladder via the irrigation line and catheter, becomes contaminated with new substances and fluids in patients undergoing bladder irrigation therapy. These substances include blood, urine, metabolites, drug metabolites, bacteria, viruses, and potentially fungi. Ideally, all these components entering the irrigation fluid during the procedure should be extracted to obtain a purified solution, which is then returned to the reservoir. In this way, the irrigation fluid is available for reuse.

[0012] A filter assembly is used to purify the rinsing fluid. The filter function must be selected such that the purified rinsing fluid contains no blood or blood components, or at least that these are reduced to a biologically acceptable concentration. Furthermore, odor-causing and chromatic components must be removed from the rinsing fluid to obtain a transparent, odorless, and reusable rinsing fluid. Additionally, bacteria, viruses, and their components must be removed or deactivated from the rinsing fluid as far as possible, ideally producing a sterile rinsing fluid. Otherwise, the filter assembly leaves the initial chemical composition of the rinsing fluid, as supplied by the manufacturer, as unaffected as possible.In the case of a saline solution, the filter arrangement has no or only a negligible effect on the NaCl concentration. If necessary, the biologically or medically desired NaCl concentration must be restored after filtration by adding appropriate ions.

[0013] To meet these minimum purification requirements for the recycling of a used rinsing fluid, at least one filter of the following type is preferably suitable: surface filter, depth filter, membrane filter, sieve filter, particle filter, suspended solids filter, activated carbon filter, ion exchanger, distillation filter, reverse osmosis filter, mechanical filter unit, centrifugal filter, hemofilter, leukocyte filter, platelet filter, glass fiber filter, ceramic filter, metal filter, polymer fiber filter, sterile filtration using membranes with a pore size ≤ 0.22 µm.

[0014] The filter arrangement is positioned along the drainage line such that the used and contaminated rinsing fluid flowing through the drainage line passes through at least one of the aforementioned filters, thereby coming into contact or interacting as completely as possible with the respective filter-specific filter surface. After passing through the at least one filter, the rinsing fluid, present as permeate, can already possess the properties formulated above as minimum requirements for reuse of the rinsing fluid and thus be returned directly to the storage container. If further purification measures are necessary, several identical or other types of filters, as described above, can be combined in a fluidically interconnected, serial sequence to meet hygiene standards and other medical requirements for bladder irrigation.

[0015] A supplementary, preferred measure to ensure the provision of a high-quality rinsing fluid from the storage container also provides that at least one disinfection unit of the following type is arranged on or in the storage container: thermal disinfection unit, UV light disinfection unit, dispensing unit of oxygen radicals, dispensing unit of an antibiotic-containing liquid, dispensing unit of a chemical disinfectant, dispensing unit of protein denaturants or enzyme inhibitors, disinfection unit by means of aerosol formation.

[0016] The selection and configuration of the disinfection unit, which is preferably to be provided additionally, serves the purpose and goal of coming as close as possible to the ideal case described at the beginning, i.e., achieving a sterile state of the rinsing fluid.

[0017] In a preferred embodiment, at least one temperature control unit of the following type is additionally arranged on or in the reservoir and / or on or in the irrigation line: infrared radiation, resistive heating element, ultrasonic heat source, heat source by exothermic chemical reaction. This preheats the irrigation fluid flowing into the patient's bladder via the irrigation line and the bladder catheter, preferably to body temperature or to a therapeutically advantageous temperature. By additionally arranging a temperature sensor in or on the irrigation line, it is possible to control the temperature.

[0018] To control the flow of irrigation fluid into the patient's bladder, a pump is installed along the irrigation line. This pump initiates a flow of irrigation fluid from the reservoir towards the bladder catheter. A roller pump is a particularly suitable pump. However, other pumps from the positive displacement or centrifugal pump categories are also suitable, such as piston pumps, diaphragm pumps, gear pumps, screw pumps, vane pumps, centrifugal pumps (single-stage and multi-stage), axial pumps, or an ejector.Using a weight sensor for differential weight detection of the reservoir including the rinsing fluid in the reservoir or a flow sensor, the amount of rinsing fluid flowing out of the reservoir by the pump along the rinsing line can be determined and set or specified as part of a control of the rinsing fluid rate, which is determined by the delivery capacity of the pump.

[0019] To prevent excessive pressure buildup in the bladder, the pressure can be additionally monitored using a pressure sensor installed in or on the irrigation line. The sensor signals obtained from the pressure sensor can also be used to control the irrigation fluid flow rate.

[0020] As an alternative to a pump positioned along the irrigation line, the reservoir can also be located above the patient, or rather above the height of their bladder, as is common practice in current systems. The irrigation fluid then flows through the irrigation hose and bladder by gravity. The irrigation rate, or flow rate, is adjusted by the height of the reservoir above the patient and by an adjustable hose clamp. In this case, a pump further down the drainage line is also used to subsequently fill the higher reservoir with the purified fluid.

[0021] The irrigation fluid, containing impurities, that exits the bladder after flushing flows through the drainage line, which is fluidically connected to the bladder catheter, and empties into an intermediate storage container. The drainage of the used irrigation fluid from the bladder through the drainage line occurs largely without pressure, as the intermediate storage container is preferably positioned gravimetrically below the bladder.

[0022] The intermediate storage container is preferably made of polymer and allows the liquid to be extracted via a hose connection or a hose outlet inserted into the intermediate storage container. The intermediate storage container is preferably designed as a light-transparent collection bag or in the form of a rigid container.

[0023] Another advantage of the intermediate storage tank is that it serves as a sedimentation system or pre-treatment stage, separating larger or heavier components from the used rinsing fluid. For this purpose, a filter unit is preferably integrated into the intermediate storage tank, which separates out larger and / or heavier components from the fluid. This filter unit can include at least one filter, such as a sieve, porous textile structures like nonwovens, felts, or cotton wool, or glass wool, or made of an open-pore foam, such as a sponge structure.

[0024] The use of an intermediate container also has the advantage that the used rinsing fluid drains from the bladder due to gravity and the pressure of the incoming rinsing fluid, thus preventing overpressure from building up in the bladder. In this case, the rinsing fluid would have to be pumped back through the filter unit into the reservoir.

[0025] From this intermediate storage tank, a further fluid line leads to the filter arrangement, as described above, in which the filtration or purification of the used rinsing fluid takes place.

[0026] To determine the degree of contamination and the amount of used irrigation fluid flowing from the bladder, an optical sensor for color measurement is arranged along the drainage line and / or upstream of one of the downstream filters to measure hemorrhage. Examples of optical sensors include transmitted or reflected light sensors with single-array or multi-array photodiodes, CCD or CMOS camera chips, or photomultipliers. Incandescent bulbs, LEDs, or semiconductor lasers can serve as the light source. A pressure sensor and / or a flow sensor are also preferably arranged along the drainage line.

[0027] Along the aforementioned, downstream fluid line, which in the context of this description is part of the drainage line, a further pump is arranged for the controlled conveyance of the rinsing fluid collected in the intermediate storage tank and containing impurities into and through the filter assembly. This pump initiates a fluid flow towards the filter assembly. This further pump, which, like the aforementioned pump arranged along the rinsing line, can be selected from the previously mentioned pump alternatives, and is particularly preferably designed as a roller pump, is to be selected and operated according to the requirements of the downstream filter assembly in order to convey the rinsing fluid to be cleaned through the filter assembly at a flow velocity and rate matched to the filter assembly, with the aim of achieving the best possible filtration result.

[0028] A weight sensor, used to measure the weight of the intermediate storage tank and the used rinsing fluid it contains, allows for the measurement of both the used rinsing fluid flowing into the intermediate tank, preferably when the pump along the fluid line leading from the intermediate storage tank is inactive, and the amount of rinsing fluid pumped from the intermediate storage tank to the filter assembly. Comparing these weight values ​​with the continuously measured weight of the reservoir also allows for the determination of the difference between the incoming and outgoing rinsing fluid, the latter additionally containing the urine excreted by the patient. From this difference, the balance value, which is important for diagnostics, is calculated.

[0029] The proposed arrangement can be operated in a first, simple mode based on empirically determined operating parameters for the pumps arranged along the flushing and drainage line. By incorporating the described sensors, such as temperature sensors, pressure sensors, flow sensors, optical sensors, weight sensors, and optionally ion-selective sensors, the resulting sensor signals can be used as control variables. These signals can be transmitted wired or wirelessly to an evaluation and control unit, where they are appropriately analyzed. Preferably, the evaluation and control unit is connected wirelessly or via a wired connection to a visualization unit that displays the acquired sensor signals and / or derived information visually. A qualified person can then view this information and take appropriate measures for the operation of the arrangement.The measures can not only involve manual intervention in the delivery rates of both pumps along the flushing and drainage line, but can also include the performance of the filter assembly, the disinfection unit or the temperature control unit, as well as providing information to personnel, for example regarding the need to empty the disposal reservoir or refill the flushing fluid into the storage tank.

[0030] As an alternative to, or in combination with, the visual display of the information acquired by the sensors, the evaluation and control unit preferably features algorithm-based or AI-based signal and data evaluation and image analysis. This enables, for example, color characterization and / or determination of the hemoglobin concentration in the used rinsing fluid along the drainage line based on the acquired optical sensor signals. Based on this information or further algorithm- or AI-supported sensor signal evaluation results, self-optimizing control of the operating parameters relating to the filter arrangement, the disinfection unit, the temperature control unit, and the pumps along the rinsing and drainage line is performed, and / or based on at least one of the control parameters...The AI-based evaluation generated a perceptible alarm signal based on the decision criterion.

[0031] Furthermore, in addition to the optical sensor along the drainage line, which obtains color information from the used and contaminated flushing fluid, further sensors can be provided for the quantitative and / or qualitative determination of contaminants or concentration shifts resulting from the bladder flushing process, which are not based on the chromatic properties of the flushing fluid. Suitable examples include transmission sensors, chemical sensors, ion-selective sensors, pH sensors, etc.

[0032] In a further preferred embodiment, a valve arrangement, preferably designed as a two-way valve, is arranged along the flushing line, preferably downstream of the feed pump. This valve arrangement is fluidically connected to the filter arrangement via a backwash line, which in turn is fluidically connected to a disposal reservoir. The valve arrangement serves to clean the filter arrangement or individual filters as needed by backwashing. In this case, which is usually carried out regularly at specific time intervals automatically and / or depending on the process pressure, but also as needed by a person who operates the valve arrangement and initiates and monitors the backwashing process, the cleaned flushing fluid flowing from the reservoir enters the filter arrangement for cleaning purposes and subsequently flows into the disposal reservoir as flushing fluid to be disposed of.Preferably, a weight measuring sensor is attached to the disposal reservoir, which, by means of data processing in the control unit, allows an indication of the fill level of the disposal reservoir.

[0033] It is also conceivable, using suitable sensory detection and monitoring of the quality of the rinsing fluid in the fluid circuit of the solution-oriented arrangement, to automate backflushing of the filter arrangement, in particular using the algorithm or AI-based signal evaluation implemented for this purpose in the evaluation and control unit and a valve arrangement that can be automatically controlled by the control unit.

[0034] In a further preferred embodiment, the filter assembly is combined with a mechanical stimulation arrangement which, when activated, is capable of subjecting the filter assembly to mechanical oscillations or vibrations that contribute to a mechanical cleaning effect of the filter assembly. Mechanical stimulations can include ultrasound, tapping, shaking, or the transmission of a mechanical force to move elements present in the filter assembly. For this purpose, when the replaceable filter assembly is inserted, it is connected to the stimulation arrangement permanently installed in the device. Alternatively to or in combination with the stimulation arrangement, the filter assembly is connected to a cleaning unit that interacts mechanically with at least one surface attributable to the filter assembly.In this context, it is conceivable that brushes are present in the filter arrangement, which wipe the filter surface, or mechanically movable filter elements which move superficially against a mutual surface or edge and thus remove deposits.

[0035] Since the patient typically excretes one to three liters of urine per day, this additional fluid must be removed from the solution. For this purpose, a further valve arrangement, e.g., in the form of a three-way valve, is preferably arranged downstream of the additional pump, which pumps fluid from the intermediate storage tank into the filter arrangement, so that a portion of the fluid can be directed into the disposal reservoir at regular intervals or under sensor control.

[0036] In a further preferred embodiment of the solution-based arrangement, the reservoir has a fluidic inlet through which fresh rinsing fluid can be supplied. Particularly in the case of the backflushing and cleaning of the filter assembly described above, where rinsing fluid is taken from the otherwise closed fluid circuit of the solution-based arrangement, there is a need for replacement and corresponding refilling with fresh rinsing fluid. Preferably, the fluidic inlet, in the form of a fluid line, is fluidically connected to a fresh rinsing fluid reservoir, from which fresh rinsing fluid can be fed into the fluid circuit of the solution-based arrangement as needed. Preferably, a further valve arrangement is arranged along the fluidic inlet.

[0037] Particularly when using this solution-oriented arrangement in a clinical setting, there is a requirement for mobile and easy handling of the arrangement on site, i.e., at or next to a patient's bed. For this purpose, the arrangement is mounted on a mobile base that is designed to be easily moved manually on a flat surface or to be mounted on casters.

[0038] For cleaning and maintenance purposes, the flushing line, the drainage line, the filter assembly, the intermediate storage tank, the disposal reservoir and / or the storage tank can each be designed individually as replaceable modules. Brief description of the invention

[0039] The invention is described below by way of example, without limiting the general concept of the invention, with reference to the drawing. It shows: Fig. 1 Block diagram of a solution-oriented arrangement for performing a bladder irrigation on a person Ways to implement the invention, industrial applicability

[0040] The in Fig.An illustrated block diagram shows a self-contained fluid circuit F, consisting of a flushing line 1 and a drainage line 2, through which a flushing fluid stored in a reservoir 3 flows in the direction indicated by the arrows. A temperature control unit T for maintaining the temperature of the flushing fluid, preferably to body temperature or slightly above, is also arranged in or on the reservoir 3. A pump 4, a pressure sensor 5, and a temperature sensor 6 are mounted along the flushing line 1 downstream of the reservoir 3; the order of sensors 5 and 6 can also be reversed. The flushing line 1 opens into the bladder of a patient 7 via a bladder catheter with at least two lumens (not shown).The drainage line 2 is also fluidically connected to the bladder catheter, through which the rinsing fluid containing impurities and subsequently used is drained from the bladder of patient 7.

[0041] Along the drainage line 2, in the direction of flow, an optical sensor 8 for determining bleeding, an optional flow sensor 9 and an intermediate storage container 10 are arranged.

[0042] Via a further section of the drainage line 2, the intermediate storage tank 10 is fluidically connected to a pump 11 such that the used rinsing fluid in the intermediate storage tank 10 is fed to a filter assembly 12, in which the used rinsing fluid, containing impurities, is purified and then flows back into the reservoir 3. The filter assembly 12 is designed and selected such that at least blood or blood components, odorous and chromatic substances, or other substances or molecules that impair the medical purpose of the rinsing are removed from the contaminated rinsing fluid.Suitable filters for this purpose include surface filters, depth filters, membrane filters, sieve filters, particle filters, suspended solids filters, size exclusion filters, activated carbon filters, ion exchangers, distillation filters, reverse osmosis filters, mechanical filter units, centrifugal filters, and sterile filtration using membranes with a pore size of less than or equal to 0.22 µm.

[0043] The reservoir 3, containing the fresh or purified irrigation fluid intended for bladder irrigation, is combined with a disinfection unit 13, for example, in the form of a UV lamp, which converts or maintains the irrigation fluid in a state that is as germ-free as possible. In addition to the aforementioned UV lamp, a thermal disinfection unit, a dispensing unit for oxygen radicals, a dispensing unit for an antibiotic-containing fluid, a dispensing unit for a chemical disinfectant, a dispensing unit for protein denaturants, enzyme inhibitors or DNases / RNases, or a disinfection unit using aerosol generation are also suitable as disinfection units 13, either alternatively or in combination.

[0044] For the purpose of cleaning the filter assembly 12 as needed by means of backwashing, a valve assembly 15 is provided, preferably located downstream of the feed pump 4 along the flushing line 2, which supplies the previously filtered flushing fluid from the storage tank 3 directly to the filter assembly 12 via a backwash line 14. The flushing fluid exiting the filter assembly 12 for the purpose of filter cleaning then enters a disposal reservoir 16.

[0045] The sensor signals of at least one of the following sensors, i.e., temperature sensor 6, pressure sensor 5, flow sensor 9, optical sensor 8, weight sensor for measuring the weight of the storage container 3 including the rinsing liquid contained therein (not shown), weight sensor for measuring the weight of the intermediate storage container 10 including the used rinsing liquid contained therein (not shown), weight sensors for measuring the weight of the disposal reservoir 16 including the respective rinsing liquid contained therein (not shown), and, if applicable,Further substance concentration and pressure sensors within the closed fluid circuit F transmit data wirelessly or via wired connections to an evaluation and control unit 17, which, based on at least one of the sensor signals, wirelessly or via wired connections controls at least one of the following units: flow direction of the filter arrangement 12, disinfection unit 13, temperature control unit T, feed pump 4, 11, along the rinsing 1 and drainage line 2, valve arrangement 15.

[0046] A fluidic inlet 18 also opens into the reservoir 3, through which fresh rinsing fluid can be supplied as needed, for example, after filter cleaning by backwashing, during which some of the rinsing fluid contained in the fluid circuit F is lost. For this purpose, a fresh rinsing fluid reservoir 19 is connected to the fluidic inlet 18, which is designed as a fluid line. A further valve arrangement 20, which can be operated manually or automatically via the evaluation and control unit 17, is arranged along the fluidic inlet 18.

[0047] Optionally, a stimulation arrangement 21 is mounted on the filter assembly 12. When activated, this stimulation arrangement sets the filter assembly 12 into mechanical vibrations to initiate filter cleaning. The mechanical vibrations, which cause the filter assembly 12, or at least parts of it, to vibrate at frequencies up to the ultrasonic range, are capable of removing surface material deposits. Alternatively, or in combination with the stimulation arrangement 21, the filter assembly 12 is connected to a cleaning unit 22. This cleaning unit interacts mechanically with at least one surface attributable to the filter assembly 12, thereby scraping or abrading off surface material deposits.
