Description

[0001] Medical transfer system for a medical peristaltic pump, medical peristaltic pump, and procedures for a medical peristaltic pump

[0002] Description

[0003] Technical field

[0004] The present disclosure relates to a medical transfer system for a medical peristaltic pump according to claim 1, a medical peristaltic pump according to claim 3, and a method for a medical peristaltic pump according to claim 15.

[0005] The liquid dosing of medicinal substances or the transfer of blood in extracorporeal blood therapy is carried out using a medical peristaltic pump and a medical transfer system. The latter consists of a tube and a permanently attached clamp for securing the tube. A rotary or linear displacement unit of the peristaltic pump imparts a peristaltic motion to the tube, thereby transferring the fluid within the tube, for example, from a drug container to an access point on the patient.

[0006] A medical administration system is, for example, an infusion device, particularly a single-use item, such as an infusion set, consisting of a drug container, tubing, and a tubing clamp. The tubing clamp is designed to engage its clamping action upon insertion into a fitting on the peristaltic pump. This ensures that no uncontrolled "free flow" can occur when the tubing is connected to the pump.

[0007] State of the art

[0008] A peristaltic pump of this type is shown, for example, in patent EP 0 484 717 B1 of the applicant. It has a hose receptacle for a hose and a displacement unit with slide-type displacers arranged side by side and transversely to the hose receptacle so as to be linearly movable. The hose is inserted into the hose receptacle and a housing flap is closed. When the housing flap is closed, the displacers, actuated at a time offset, work against the hose, causing it to be pinched against the housing flap and resulting in peristaltic movement of the hose, which in turn leads to the pumping of the fluid.

[0009] To ensure, as mentioned above, that fluid flows to the patient only when needed – that is, only while the peristaltic pump is operating, and not, for example, when the tubing is inserted into the pump – a redundant clamping system is provided. Firstly, the tubing itself has the aforementioned hose clamp, and secondly, the peristaltic pump has an internal clamping mechanism whose clamp is activated by inserting the tubing and closing the housing cover.

[0010] The applicant's product range includes peristaltic pumps under the name Infusomat® spaceP. |us It is known that different colors of hose clamps are detected and evaluated optoelectronically. The detected color is used to automatically identify the set in use / inserted, and the peristaltic pump is automatically preset with regard to the treatment associated with that set.

[0011] The patent application DE 10 2021 215 067 A1, filed by the applicant, discloses a method for automatically distinguishing hose clamp colors. This involves a measurement algorithm that illuminates the hose clamp within the peristaltic pump with RGB light sources and determines the clamp's color based on the measured remissions. For colors whose remissions differ only insufficiently across the RGB principal wavelengths, it is proposed to add a predetermined amount of IR absorber to the material of the affected hose clamps / colors. In this way, hose clamps with identical or very similar remissions in the visible spectrum can be distinguished and identified based on their different remissions in the IR spectrum.A disadvantage is that hose clamps of the same color are indistinguishable, meaning that, for example, a counterfeit cannot be identified and the peristaltic pump may be operated with an unintended, copied or outdated transfer system.

[0012] Summary of Revelation

[0013] The objective of the present disclosure, in contrast, is to provide a medical transfer system for a medical peristaltic pump that eliminates or at least reduces the disadvantages of the prior art. Furthermore, the objective is to provide a medical peristaltic pump and a method for controlling the peristaltic pump that eliminates or at least reduces the disadvantages of the prior art.

[0014] The problem is solved by a medical transfer system for a medical peristaltic pump with the features of claim 1, a medical peristaltic pump with the features of claim 3, and a method with the features of claim 15. Preferred embodiments are described in the dependent claims.

[0015] A fundamental concept of the present disclosure is to provide a peristaltic pump configured to detect the remission of a hose clamp of a transfer system in the visible spectrum and to assign a predetermined, i.e., preferably retrievably stored, reference remission to this detected remission in the visible spectrum. This reference remission must, firstly, coincide sufficiently with the detected remission of the hose clamp in the visible spectrum, and secondly, extend into an invisible spectrum, preferably the near-infrared. The assignment occurs when there is sufficient overlap, particularly when the reference remission in the visible spectrum adequately represents the color of the hose clamp. In the invisible spectrum, the assigned reference remission exhibits remission values ​​that represent an original of the hose clamp.Preferably, the remission of the original in the invisible spectrum is sufficiently low, which is achieved by adding an absorber effective in the invisible spectrum, leading to a sufficient reduction in the remission of the original in the invisible spectrum. Hose clamps of the same color—that is, hose clamps whose remissions sufficiently match in the visible spectrum—can thus be distinguished in the invisible spectrum according to the disclosure if the remissions of the hose clamps in the invisible spectrum deviate from the reference remission or deviate in different ways. If the remission of a hose clamp in the invisible spectrum deviates from the predetermined reference remission, it can be concluded, in particular, that the hose clamp in question is not an original.

[0016] According to the disclosure, a medical transfer system intended for use with a medical peristaltic pump has at least: a tube designed and configured to be inserted, at least section by section, into a tube receptacle or pump section of the peristaltic pump to transfer a fluid from a reservoir to a patient; a (non-destructively) permanently attached tube clamp designed and configured to be inserted, preferably into a receptacle of the peristaltic pump, to be irradiated with light in the visible spectrum and with light in an invisible spectrum, preferably near-infrared (NIR), in order to detect / determine its remission in the visible spectrum and its remission in the invisible spectrum; a predetermined reference remission in the visible spectrum or color of the tube clamp.wherein a predetermined reference remission in the visible spectrum or color is assigned to a predetermined operating parameter of the peristaltic pump, preferably a predetermined control method, a predetermined basic setting, a predetermined flow rate, a predetermined (delivery) pressure, a predetermined drug library, or the like. Furthermore, it is provided that upon detection of the predetermined reference remission in the visible spectrum or color of the tubing clamp, the predetermined operating parameter of the tubing clamp can be activated / released / initialized. This means that upon detection of the predetermined reference remission in the visible spectrum or color of the tubing clamp, a first of two conditions is met in order to be able to activate / release / initialize the predetermined operating parameter of the tubing clamp.

[0017] According to the disclosure, the hose clamp of the transfer system also has a predetermined reference remission in the invisible spectrum, to which a predetermined attribute of the transfer system is assigned. Preferably, this attribute is a unique feature, version, or series of the transfer system. According to the disclosure, activation / release / initialization of the predetermined operating parameter of the peristaltic pump is provided if the predetermined reference remission is detected in the invisible spectrum of the hose clamp. Conversely, if a sufficient deviation from the predetermined reference remission is detected in the invisible spectrum, deactivation / blocking / termination of the predetermined operating parameter of the peristaltic pump is provided.

[0018] According to further training, the predetermined reference remission in the visible spectrum or color of the hose clamp is green or white.

[0019] According to further training, the predetermined attribute is an originality of the transition system or a version or series of the transition system.

[0020] According to the disclosure, a medical peristaltic pump is provided, which is designed in particular as a transfusion pump, infusion pump, pain pump, or enteral pump for use with the aforementioned medical administration system. It has a receptacle, preferably in the form of a shaft or a slot, which is designed and configured to receive the tubing clamp of the administration system. A light unit of the clamp module is configured to emit light in the visible spectrum and light in an invisible spectrum onto the tubing clamp. The light in the visible spectrum is preferably in the principal wavelengths of red, green, and / or blue, while the light in the invisible spectrum is preferably in the near-infrared. Preferably, the light unit is configured to emit the light in the visible spectrum at the principal wavelengths of red (630 nm ± 16 nm), blue (467 nm ± 25 nm), and green (520 nm ± 33 nm).Preferably, the lighting unit is configured to emit light in the invisible spectrum at near-infrared wavelengths greater than 800 nm, preferably greater than 780 nm. A detector unit of the peristaltic pump, in particular a photodetector unit, is configured to detect and evaluate light reflected or remitted by the hose clamp, that is, remission from the hose clamp in the visible spectrum, preferably in the principal wavelengths of red, green, and blue, and remission from the hose clamp in the invisible spectrum, preferably in the near-infrared. Preferably, the detected remission is a remission curve extending across both spectra. Alternatively or additionally, remission in the visible spectrum is detected only in the principal wavelengths.According to the present disclosure, the detector unit is configured to determine a predetermined reference remission, extending across both spectra, based on the remission detected in the visible spectrum. Preferably, the predetermined reference remission is a predetermined reference remission curve. The predetermined reference remission is preferably stored in a memory unit of the medical peristaltic pump and can be accessed by the detector unit. Furthermore, according to the present disclosure, the detector unit is configured to determine any deviation in the invisible spectrum between the remission detected in the invisible spectrum and the determined, predetermined reference remission. Preferably, the detector unit includes an evaluation module for determining the deviation(s).According to the disclosure, the detector unit is configured to activate / release / initialize the predetermined operating parameter of the peristaltic pump in the event of a sufficiently small deviation, and conversely, to deactivate / block / terminate the predetermined operating parameter of the peristaltic pump in the event of a sufficiently large deviation.

[0021] According to the disclosure, a medical peristaltic pump is thus created that can differentiate between tubing clamps of medical administration systems whose remissions in the visible spectrum coincide or are the same color, based on their remissions in the invisible spectrum. This allows, for example, the identification of a counterfeit or an outdated version of the administration system and, if necessary, the initiation of countermeasures by issuing a warning and / or stopping operation. According to the disclosure, the tubing clamp material consists of a base material and a predetermined color mixture. The material (base material and color mixture) determines the tubing clamp's remission in the visible spectrum, or its color, and its remission in the invisible spectrum.

[0022] Preferably, the material of the hose clamp is reflective in the invisible spectrum, preferably in the near-infrared. In particular, this reflectance is greater than 40% at 1000 nm, preferably between 30% and 90% between 850 nm and 1050 nm.

[0023] Preferably, the base material of the hose clamp is a thermoplastic polymer based on polyolefin or polyoxymethylene (POM).

[0024] According to the disclosure, the material of an original hose clamp (attribute is "original") consists of the base material, the predetermined color mixture, and, furthermore, an absorber effective in the invisible spectrum, preferably a NIR absorber, in a predetermined concentration. According to the disclosure, this material results in the aforementioned remission in the visible spectrum, or the aforementioned color of the hose clamp, and a reduced remission in the invisible spectrum.

[0025] Due to the absorber present in the original material, the remission of the original hose clamp in the invisible spectrum is therefore lower than the remission of hose clamps that are the same color and indistinguishable to the human eye, but whose material does not contain the absorber.

[0026] In other words, the detectable remission of the original hose clamp - due to the predetermined absorber - in the invisible spectrum is smaller than the detectable remission in the invisible spectrum of the hose clamp without absorber.

[0027] This enables invisible copy protection for colored hose clamps, allowing a colored original to be clearly distinguished from a similarly colored non-original or counterfeit. According to further training, the detector unit, particularly its evaluation module, is configured to determine an attribute of the hose clamp based on the deviation detected in the invisible spectrum. Specifically, the attribute is "original" or "non-original" or "current version / series" or "obsolete version / series".

[0028] According to further training, the deviation detected in the invisible spectrum is defined as an area difference between the remission curve detected in the invisible spectrum and the predetermined reference remission curve.

[0029] The deviation determined in the invisible spectrum is sufficiently large if it is at least 10% to 40% at 1000nm, preferably between 10% and 60% between 850nm and 1050nm.

[0030] According to a further development, the detector unit, in particular its evaluation module, is configured to determine a color of the hose clamp from the remission detected in the visible spectrum, preferably in the principal wavelengths of red, green and blue, preferably at least green, white, red, blue, magenta, grey, orange, violet and / or yellow.

[0031] According to the disclosure, the detector unit, in particular its evaluation module, is designed to be able to distinguish hose clamps with the same remission in the visible spectrum, i.e. with the same color, even if the remissions determined for the hose clamps in the invisible spectrum differ from the reference remission.

[0032] Within the framework of the disclosure, remissions in the visible spectrum are considered to be of equal value if their difference from each other is less than 5%.

[0033] According to further training, an assignment is provided that can be called up by the evaluation unit, preferably in the form of a lookup table or database. The assignment is preferably stored or saved in a memory unit of the terminal module or the medical peristaltic pump.

[0034] In this mapping, possible remissions in the visible spectrum, i.e., possible colors, are assigned predetermined reference remissions. Preferably, remission curves in the visible spectrum are assigned predetermined reference remission curves.

[0035] Preferably, the detector unit is configured to detect the remission in the visible spectrum, to call up the assignment and to determine the reference remission that is assigned to the detected remission in the visible spectrum.

[0036] According to further training, the detector unit, in particular its evaluation module, is configured to determine the deviation of the remission measured in the visible spectrum from the predetermined reference remissions. This deviation then provides a basis for determining which of the predetermined reference remissions best corresponds to the color of the illuminated hose clamp.

[0037] According to further training, the deviation of the remission determined in the visible spectrum is a difference in area or a difference in at least one of the principal wavelengths.

[0038] According to further training, the detector unit, in particular its evaluation module, is designed to determine, in addition to the remission detected in the visible spectrum, the remission from the predetermined reference remissions that has the smallest deviation from the remission detected in the visible spectrum.

[0039] A medical peristaltic pump as disclosed is designed, in particular, as an infusion pump or blood pump and has a clamping module comprising at least the intake, the light unit, and the detector unit, preferably with a detector module for the aforementioned detection and with an evaluation module for the aforementioned investigations. The medical peristaltic pump preferably comprises a set of at least two transfer systems whose colors and / or remissions are sufficiently similar or identical in the visible spectrum. The material of one of the two tubing clamps has an absorber effective in the invisible spectrum, whereas the material of the other, second tubing clamp does not.Despite having the same color, the remission of the first hose clamp is, as disclosed, lower in the invisible spectrum than the remission of the second hose clamp, thus making the two hose clamps distinguishable in the invisible spectrum. Preferably, the first hose clamp with the absorber is identified or attributed as the original by its presence. The second hose clamp, without the absorber in the invisible spectrum, then represents the non-original of the same color.

[0040] A method is disclosed for a medical peristaltic pump, preferably designed according to at least one aspect of the preceding description. The method comprises the steps:

[0041] - Receiving a hose clamp of a transfer system designed according to at least one aspect of the preceding description, of an infusion article, preferably an infusion tubing set, in or on a receptacle of the medical tube pump;

[0042] - Emitting light in the visible spectrum and light in an invisible spectrum onto the hose clamp, preferably in the main wavelengths of red, green and blue and preferably in the near-infrared, via a lighting unit of the medical hose pump;

[0043] - Detecting the light reflected from the hose clamp via a detector unit of the medical hose pump, preferably via a detector module of the detector unit; and from this

[0044] - Determining remission in the visible spectrum, preferably in the principal wavelengths of red, green and blue, and remission in the invisible spectrum, preferably determining a remission curve extending in both spectra via the detector unit, preferably via an evaluation module of the detector unit or the medical peristaltic pump.

[0045] According to the disclosure, the method comprises the following steps: - Determining a predetermined reference remission, preferably a reference remission curve extending across both spectra, as a function of the remission determined in the visible spectrum, via the detector unit, preferably the evaluation module; and in the invisible spectrum

[0046] - Determining a deviation of the remission measured in the invisible spectrum from the predetermined reference remission, via the detector unit, preferably the evaluation module, and

[0047] - Optional activation / release / initialization of the predetermined operating parameter of the peristaltic pump in the event of a sufficiently small detected deviation, or deactivation / blocking / aborting of the predetermined operating parameter of the peristaltic pump in the event of a sufficiently large detected deviation.

[0048] The advantages regarding the distinguishability of medical infusion systems with hose clamps of the same color based on the determined deviation in the invisible spectrum were explained in detail in the course of describing the medical infusion system and the medical hose pump according to the disclosure and also apply to the method according to the disclosure.

[0049] According to a further development, the method has a step of determining an attribute of the hose clamp depending on the determined deviation in the invisible spectrum, in particular the attribute original and non-original, via the detector unit, preferably its evaluation module.

[0050] According to a further development, the method includes a step for determining the color of the hose clamp based on the detected / determined remission in the visible spectrum, preferably based on the detected / determined remissions in the principal wavelengths of red, green, and blue, via the detector unit, preferably its evaluation module. Preferably, at least green, white, red, blue, magenta, and / or gray can be determined. Preferably, an assignment is provided, which can be accessed by the detector unit, preferably its evaluation module, preferably a lookup table or a database, in which remissions in the visible spectrum, preferably remissions in the principal wavelengths of red, green, and blue, are assigned to predetermined reference remissions.

[0051] According to a further training, the procedure has a step of determining a deviation of the remission determined in the visible spectrum from the predetermined reference remissions, via the detector unit, preferably its evaluation module.

[0052] Preferably, a deviation of the remission determined in the visible spectrum is defined as an area difference or a difference in at least one of the principal wavelengths.

[0053] According to a further development, the method has a step of determining one of the predetermined reference remissions that has the smallest deviation from the remission determined in the visible spectrum, via the detector unit, preferably its evaluation module.

[0054] The procedure according to the disclosure is completed before treatment of a patient begins, in particular before a patient is connected to the hose pump.

[0055] According to the disclosure, a computer-readable storage medium may be provided which includes instructions which, when executed by a computer, cause it to perform the process steps of the method according to at least one aspect of the preceding description.

[0056] Any disclosure relating to the medical transfer system and the medical tube pump according to the present disclosure applies to the procedure according to the present disclosure, and vice versa.

[0064] Fig. 6 is a representation of a method for determining a deviation of a remission of a hose clamp with a predetermined color from a reference remission of the hose clamp in an invisible spectrum, according to an embodiment of the present disclosure; and

[0065] Fig. 7 is a diagram of the remission curves of the two identically colored tubing clamps, which sufficiently overlap in the visible spectrum but differ from each other in the invisible spectrum. Figure 1 shows a medical peristaltic pump 1, designed as an infusion device or infusion pump, from the front. The peristaltic pump 1 has a housing 2 with a front panel 4 and a tubing compartment cover 10 hinged to the underside, on which a control panel 6 and a display 8 are arranged. A tubing compartment 12 – also referred to as tubing receptacle or pump section – is closed off by the tubing compartment cover 10, into which an infusion tube 14 of a medical administration system 14, 18 according to the disclosure is inserted (see Figure 2).

[0066] Figure 2 shows the infusion set 1 according to Figure 1 with the tubing compartment cover 10 open. As shown in Figure 2, the infusion tubing 14 extends from the right, starting from an infusion container (not shown) of the distribution system 14, 18, into the elongated tubing compartment 12. Closing the tubing compartment cover 10 secures the infusion tubing 14 in the tubing compartment 12. The tubing compartment cover 10, when closed during operation (see Figure 1), fixes the infusion tubing 14 in its operating position and forms a wall against which displacement elements (not shown) arranged behind the tubing compartment 12 compress the infusion tubing 14 in a peristaltic sequence, thus pumping the fluid to be infused towards the patient. The tubing compartment 12 can therefore also be referred to as the pump section.

[0067] To ensure that the fluid flow to the patient occurs exclusively through the operation of the peristaltic pump 1 and not prematurely - for example, due to gravity effects when the infusion tube 14 is inserted into the tube compartment 12 - a redundant clamping system is provided.

[0068] Firstly, a hose clamp 18, as disclosed, is provided on the infusion tubing 14 itself. Secondly, the peristaltic pump 1 has a clamping module 20 with an integrated clamping mechanism (not shown). The clamping mechanism is activated when the infusion tubing 14 is inserted by inserting and sliding the hose clamp 18 into a receptacle 22 of the clamping module 20 and subsequently closing the tubing compartment cover 10. Fig. 3 shows two medical transfer systems 14, 18, 14', 18' with hose clamps 18, 18' of the same color. One of the hose clamps 18, 18', as disclosed, is marked as the original by means of a near-infrared absorber; the other, second hose clamp 18', is not. The latter, second hose clamp 18' thus represents a non-original of the same color.To the human eye, the hose clamps 18, 18' are indistinguishable due to their identical color and shape. When inserted into the peristaltic pump 1, their color would activate / release / initialize the same color-specific operating parameter of the pump 1. Both clamps have a tapered elongated slot, in the widened section of which the infusion tubing 14, 14' lies before the hose clamp 18, 18' is inserted into the receptacle 22 (see Figs. 2 and 5). When the hose clamp 18, 18' is inserted into the receptacle 22, it actuates the machine's clamping mechanism, which clamps the infusion tubing 14, 14' off the hose clamp 18, 18', thus preventing uncontrolled fluid flow before the peristaltic pump 1 starts.By opening the hose compartment cover 10, the hose clamp 18, 18' is pulled over the infusion hose 14 on its hook (from right to left in Fig. 3) and thus closes it.

[0069] Fig. 4 shows a printed circuit board 24 of the medical peristaltic pump 1 according to Fig. 1 with a light unit 26, 28 and a detector unit 30, 32, wherein the detector unit comprises an optical detector module 30 and an evaluation module 32. The light unit has a combined RGB LED 26, which emits in the main wavelengths of red, green and blue, as well as a closely spaced infrared LED, which emits in the near-infrared.

[0070] Fig. 5 shows a section AA of the clamping module 20 of the medical peristaltic pump 1 as defined in Figure 2, according to Figures 1 and 2. The clamping module 20 is isolated and cut below the infusion tubing, so that the tubing is not visible. The perspective view is the same as in Figure 2. Accordingly, the recess 22 of the clamping module 20 in Figure 5 extends from the lower left to the upper right. The tubing clamp 18 is inserted into the recess 22 (dashed line). In Figure 5, the circuit board 24 is attached to the rear of the clamping mechanism of the clamping module and arranged such that the light unit 26, 28 and the detector unit 30 point towards the recess 22 and the tubing clamp 18.

[0071] Light 26' at the main wavelengths of red, green, and blue is emitted from the RGB LED 26 onto the hose clamp 18 shown in the image 22. Light 28' at near-infrared wavelengths is emitted from the NIR LED 28 onto the hose clamp 18. The light 30' reflected from the hose clamp strikes the detector module 30 of the detector unit, which is signal-connected to the evaluation module 32 of the detector unit 30, 32 for analysis of the reflected light 30'.

[0072] Fig. 6 shows a method for determining the deviation of the remission of a tubing clamp of a predetermined color in a medical transfer system from a reference remission of the tubing clamp in the invisible spectrum, according to an embodiment of the present disclosure. The method is described with reference to Fig. 6 and Fig. 7, which shows remission curves of the two tubing clamps 18 and 18' of the same color, the remission curves differing in the invisible spectrum. The dashed remission curve represents the original tubing clamp 18 with an NIR absorber, and thus, for a specific color, the reference remission curve. The solid remission curve represents the non-original tubing clamp 18' without an NIR absorber.

[0073] The starting point is that a transition system 14', 18' is to be inserted, although it is not yet clear whether this is an original or a plagiarism.

[0074] First, an initialization step SO of the procedure is performed, for example by putting the peristaltic pump 1 into operation and inserting the infusion tube 14' of the transfer system 14', 18' into the tube compartment 12 according to Figure 2.

[0075] The next step involves inserting S1 of the hose clamp 18' of the transfer system 14', 18' into the receptacle 22 of the clamp module 20 of the medical peristaltic pump 1. Preferably, the hose clamp 18' is secured in the receptacle 22 by closing the hose compartment cover 10.

[0076] Following this, the step S2 emits the light 26' in the visible spectrum L (see Fig. 7) and the light 28' in the invisible spectrum NIR (see Fig. 7) onto the hose clamp 18', preferably in the main wavelengths of red, green and blue and preferably in the near-infrared, via the lighting unit, or the RGB LED 26 and the NIR LED 28 of the medical hose pump 1 (see also Fig. 5).

[0077] The hose clamp 18' emits light in the visible and invisible spectrum L, NIR. The emitted light 30' according to Figure 5 therefore strikes the detector module 30 of the detector unit 30, 32 and the process continues with the step S3 of detecting the light emitted by the hose clamp 18' via the detector module 30 of the detector unit 30, 32 of the medical peristaltic pump 1.

[0078] The (photo)detector module 30 of the detector unit 30, 32 is signal-connected to the evaluation module 32 (see Figs. 4 and 5) of the detector unit 30, 32, and for the recorded hose clamp 18', the step S4 of detecting / determining a remission Rist.i in the visible spectrum L, preferably in the principal wavelengths of red, green, and blue, and a remission Rist, NIR in the invisible NIR spectrum is carried out via the evaluation module 32 of the detector unit 30, 32. It is preferred if the remission is a remission curve Rist (18') extending in both spectra L, NIR according to Figure 7.

[0079] According to the disclosure, a predetermined reference remission Rret, preferably stored in a lookup table or database and accessible from the remission L determined in the visible spectrum – that is, the left section Rist.L (18') of the recorded / determined remission curve Rist (18') in Figure 7 – is determined for the remission L determined in the visible spectrum. This reference remission Rret preferably corresponds sufficiently with the recorded / determined remission curve Rist (18') in the visible spectrum. Sufficient correspondence is preferably achieved when the deviation AL of the remission Rist.i (18) from the reference remission Rret.L is sufficiently small in the visible spectrum, that is, when the reference remission R re f,L in the visible spectrum sufficiently represents the color of the hose clamp 18' recorded in image 22 / in particular has the same color.

[0080] Accordingly, the method, as disclosed, includes the step of determining S5 a predetermined reference remission, preferably a reference remission curve Rref (18) extending in both spectra L, NIR, as a function of the remission Rist.i of the hose clamp 18' determined in the visible spectrum L, via the evaluation module 32.

[0081] Now, in the invisible NIR spectrum, the recorded / determined remission Rist.NiR (18') of the (non-original) hose clamp 18' and the reference remission Rref.NiR (18) of the (original) reference hose clamp 18 are available and can be compared.

[0082] Accordingly, the procedure, as disclosed, includes the step of determining S6 a deviation ANIR of the remission Rist.NiR (18') determined in the invisible spectrum NIR from the predetermined reference remission Rref.NiR (18), via the evaluation module 32.

[0083] Depending on the ANIR deviation, the inserted / received (non-original) hose clamp 18' can be distinguished from the (original) reference hose clamp 18.

[0084] According to a further development, the method has a step S7 determining an attribute of the hose clamp 18 as a function of the determined deviation ANIR in the invisible spectrum NIR, in particular the attribute "original" and "non-original", via the evaluation module 32. The difference area ANIR opening above 780 nm is sufficiently large in the case of the hose clamp 18' shown in Fig. 7, which indicates that the hose clamp 18' is not marked with the NIR absorber and is therefore identified as a non-original hose clamp 18' according to the disclosure.

[0085] According to a further development, the method includes a step of determining the color of the hose clamp based on the measured remission in the visible spectrum, preferably based on the measured remissions in the principal wavelengths of red, green, and blue, via the evaluation unit. Preferably, at least green, white, red, blue, magenta, gray, orange, violet, and / or yellow can be determined.

[0086] Preferably, an assignment is provided which can be called up by the evaluation unit, preferably a look-up table or a database, in which remissions in the visible spectrum, preferably remissions in the principal wavelengths of red, green and blue, are assigned to predetermined reference remissions.

[0087] According to further training, the procedure includes a step of determining a deviation of the remission determined in the visible spectrum from the predetermined reference remissions, via the evaluation unit.

[0088] Preferably, a deviation of the remission determined in the visible spectrum is defined as an area difference or a difference in at least one of the principal wavelengths.

[0089] According to further training, the procedure includes a step of determining one of the predetermined reference remissions, which has the smallest deviation from the remission determined in the visible spectrum, via the evaluation unit.

[0090] The procedure according to the disclosure is completed before treatment of a patient begins, in particular before a patient is connected to the hose pump 1.
