[0223] The device 1 for the on-site analysis of excrements, which is shown fundamentally in FIGS. 1 to 15 with regard to its structure and mode of operation, essentially consists of a removal device 2, by means of which a sample of excrement can be removed by a sample carrier 3, a feeding device 4, by means of which a new sample carrier 3 can be provided for the removal device 2, and an analysis device 5, by means of which a removed sample can be at least partially analyzed directly with the device 1.

[0224] The device 1 comprises a housing 6, to which a retaining bracket 10 is fastened to be folded up or down by means of a articulated connection 7.

[0225] By means of said retaining bracket 10, the device 1 can be attached, for example, to an edge 11 of a toilet bowl 12 of a toilet 13, as is shown with regard to the corresponding arrangement 14 according to the depictions in FIGS. 14 and 15.

[0226] The removal device 2 essentially comprises an arm element 20, which is movable relative to the housing 6 of the device 1, for moving the sample carrier 3 in an axial movement direction 21, more precisely, in an axial extension direction 22 or in an axial retraction direction 23, a guide part 25 with a guide path 26 for precisely guiding the movable arm element 20, a holder 30 for holding a sample carrier 3 on the movable arm element 20, an opening and closing unit 32 for opening and closing the holder 30, a release unit 35 for releasing a used sample carrier 3 from the holder 30, as well as activation means 38 for activating the feeding device 4, and a drive unit 40 for axially driving the movable arm element 20.

[0227] The feeding device 4 essentially comprises a translationally movable transport carriage 42, which is movable on a guide path part 44 in a feed direction 46 running transversely to the axial movement direction 21, an activation lever 48 which is rotatably mounted on an axis of rotation 50 of the transport carriage 42, a movement curve 52, on which the activation lever 48 can also be rolled off, cutting means 54 of a cutting direction (not depicted herein) for producing individual sample carriers 3, and an additional curved path 56 which slides along a guide pin 58 of the housing 6 in order to guide particularly the cutting means 54 in the cutting direction 60 transversely to the feed direction 46 and against a spring force 62 of a spring element 64, and finally a refillable magazine 66 for storing roll material 68, from which new sample carriers 3 can be cut by means of the cutting means 54.

[0228] At this point, it must also be noted that instead of roll material 68 with a suitably designed magazine (not explicitly depicted herein), other storage configurations, for example, pre-produced strip elements or the like, can also be provided as sample carriers. In this way, the cutting device 54 can possibly be further simplified or can be omitted entirely.

[0229] It goes without saying that the depicted movement curve 52 and the additional curved path 56 are only a first option of many constructive options for deflecting the activation lever 48 or the transport carriage 42 or the cutting device in a desired manner. Instead, it is also possible to use other sliding guides, in which a sliding block is guided in a sliding groove, etc.

[0230] In addition to an analysis unit 70, the analysis device 5 comprises a sensor unit 72 with a multiplicity of different sensors 73 (herein denoted only by way of example) and a data transmission unit 74 for transmitting analysis data or information to almost any receiver device, e.g., a smartphone, on which a corresponding application for visualizing and/or further analyzing the data or information is running.

[0231] For this purpose, however, the analysis unit 70 can also be situated at another location on the device, for example, in the housing 6.

[0232] For example, the analysis unit 70 comprises a microcontroller (not depicted) or the like for analysis purposes.

[0233] In this case, the analysis unit 70 and the sensor unit 72 can be in active contact with one another in a wired or wireless manner. This also applies to the data transmission unit 74 or the like already mentioned above

[0234] According to the depiction in FIG. 1, the device 1 is in a starting position 80, in which the movable arm element 20 is retracted into the guide part 25 such that the activation means 38 are already located in a groove 81 of the activation lever 48, wherein, however, the activation lever 48 has not yet been rotated about the axis of rotation 50 by the activation means 38, or if it has been rotated, then only to a negligible extent.

[0235] In this embodiment, the activation means 38 are designed, by way of example, as elevations 82 on the upper side of the movable arm element 20.

[0236] In this embodiment, said elevation 82 is designed as a pin element (not explicitly denoted again).

[0237] It goes without saying that, with a corresponding redesign of the device 1, this elevation 82 or the non-denoted pin element can also be configured on the underside 85 of the movable arm element 20.

[0238] In any case, the activation lever 48 is still in an inactivated state and is essentially still aligned perpendicularly to the axial movement direction 21.

[0239] By means of the transport carriage 42, the roll material 68 is already repositioned below the cutting means 54.

[0240] The present cutting means 54 can be designed differently, for example, as a cutting knife, ripping knife, or punching knife, so that the term cutting means 54 not only refers to cutting, but also to punching, tearing, or other cutting methods.

[0241] The transport carriage 42 is pressed upward, i.e., in the opposite direction of the actual cutting direction 60, by means of a spring force 62 of the leaf spring element 64 which is arranged in the magazine housing 87.

[0242] In this case, the cutting means 54 are preferably exchangeable with the magazine housing 87 as soon as the roll material 68 has been used up.

[0243] According to the depiction in FIG. 2 which essentially shows the magazine 66 of the device 1, it is clarified once more that the transport carriage 42 and the leaf spring element 64 interact with one another such that the transport carriage 42 is not only moved in the upward direction by the spring forces 62 against the cutting direction 60, but also in the rearward direction 88 away from the movable arm element 20.

[0244] Below the transport carriage 42, the magazine 66 is also equipped with a closure part 89, which can essentially follow the movement of the transport carriage 42 and, when inactive, can close the magazine housing 87 at the feed opening 90, from which the roll material 68 is conveyed. In this way, the roll material 68 can also be well protected, for example, from atmospheric moisture.

[0245] The holder 30 for holding the respective sample carrier 3 is arranged on the front, free end 87 of the movable arm element 20, wherein the holder 30 has two clamping elements 88 and 89 in this embodiment.

[0246] At least the second clamping element 89 can be elastically deflected by a holder actuation member 90, so that the holder 30 can be opened by the holder actuation member 90; as a result, a new sample carrier 3 can then be inserted into the holder 30 by means of the feeding device 4.

[0247] At this point, it must also be noted that, according to the depiction in FIG. 1, the second clamping element 89 is shown partially cut open in order to visualize the ramp element 91 hidden under the second clamping element 89.

[0248] Furthermore, in this embodiment, the holder actuation member 90 is designed as a ramp element 91 (cf. particularly FIG. 4), with which the second clamping element 89 can collide, so that it is deflected upward.

[0249] According to the depiction in FIG. 3, the device 1 is already shown in a more advanced feeding position 100, in which the movable arm element 20 is visualized further in the axial retraction direction 23, so that the activation lever 48 has already been rotated further about the axis of rotation 50, wherein the activation lever 48 is simultaneously supported by the movement curve 52.

[0250] As a result, the transport carriage 42 is moved towards the movable arm element 20 in the feed direction 46, and the sample carrier 3 can thus now be inserted further into the more open holder 30.

[0251] The movement of the transport carriage 42 in the feed direction 46 towards the movable arm element 20 can be easily recognized by the fact that the curved path 56 has already moved further relative to the guide pin 58.

[0252] Due to the axial movement of the movable arm element 20 in the axial retraction direction 23, the second clamping element 89 of the holder 30 is deflected upward because its curved end (not denoted again) increasingly collides with the ramp element 91.

[0253] According to the depiction in FIG. 4, the device 1 is shown in a cutting position 110, in which the movable arm element 20 is moved still further in the axial retraction direction 23, so that the transport carriage 42 is moved even further toward the movable arm element 20, and the curved path 56 is again guided further under the guide pin 58, so that the transport carriage 42 and the cutting means 54 attached thereto have been moved downward in the cutting direction 60.

[0254] In this respect, a new sample carrier 3 is now severed from the roll material 68 located in the magazine 66.

[0255] It can also be clearly seen that the second clamping element 89 has now completely collided with the ramp element 91, and the holder 30 is thus completely open, and the new sample carrier 3 can now be passed on from the feeding device 4 to the holder 30 in an unimpeded manner.

[0256] When the new sample carrier 3 is finally correctly positioned in the holder 30, the movable arm element 20 is moved in the axial extension direction 22, and the second clamping element 89 is therefore again moved away from the ramp element 91, so that, as a consequence, the holder 30 closes and the new sample carrier 3 is clamped firmly and operationally safe in the holder 30, although this is once again not explicitly shown.

[0257] According to the depiction in FIG. 5, the device 1 is shown with its housing 6 and the retaining bracket 10 arranged thereon, wherein a transfer region 111 is shown between the feeding device 4 and the removal device 2 with a sample carrier 3 positioned there by way of example. In this case, the movable arm element 20 is not shown again, wherein said movable arm element 20 normally protrudes from the outlet opening 112.

[0258] According to the depiction in FIG. 6, this is shown in connection with the drive unit 40 of the removal device 2, wherein the movable arm element 20 is shown rolled up and already guided out of the outlet opening 112.

[0259] Representative of the drive unit 40, only the drive shaft 114 with the drive roller 116 arranged thereon and the pressure roller 118 are shown, wherein the movable arm element 20 is guided between the drive roller 116 and the pressure roller 118.

[0260] Otherwise, the movable arm element 20 is largely rolled up in the housing 6.

[0261] According to the depiction in FIG. 7, the device 1 is shown with the guide part 25 folded down, so that the device 1, as shown in FIGS. 14 and 15, can be attached to the edge 11 of the toilet bowl 12.

[0262] In the present case, the guide part 25 is advantageously designed as a retaining bracket 10, so that the device 1 can be constructed in a very compact manner.

[0263] According to the depiction in FIG. 8, the guide part 25 is shown in more detail from its underside 130, wherein it can be clearly seen that the guide part 25 extends into a contamination region 132, in which the guide path 26 extends in the axial movement direction 21, and also divides a clean region 134, in which a new sample carrier 3 can be guided at least partially next to the guide path 26, and particularly the sensor unit 72 is arranged.

[0264] In this case, the clean region 134 is arranged on the side next to the contamination region 132, wherein, between the contamination region 132 and the clean region 134, a separation 136 is provided which extends with a rigid partition 138 in the axial movement direction 21 in the longitudinal extension of the guide part 25.

[0265] In this case, the partition 138 is arranged and, above all, configured such that it can be bridged by a sample carrier 3 clamped onto the holder 30.

[0266] In other words, this means that the new sample carrier 3, held on the holder 30, with its clamping side 140 is located in the contamination region 132, while the sample carrier 3 with its sensor side 142 is located in the clean region 134.

[0267] This can ensure that the sensor side 142 of a new sample carrier 3 is not already being contaminated with excrement on its path in the axial extension direction 22 because a previously used sample carrier 3 can only reach the axial height of the sensor unit 72 and maximally the axial height of the release unit 35 or a transition region 144 arranged in a radially adjacent manner.

[0268] In this embodiment, the guide part 25 is open on its underside 130, so that particularly the contamination region 132 and the clean region 134 can always be cleaned or disinfected well.

[0269] In this case, the clean region 134, as seen looking in the axial retraction direction 23, is arranged axially behind the release unit 35.

[0270] In this respect, the clean region 134, as seen looking in the axial extension direction 22, is arranged axially in front of the sensor unit 72.

[0271] The guide path 26 extends from the rear end 150 of the guide part 25 to the front end 152 of the guide part 25.

[0272] The clean region 134 extends essentially from the rear end 150 of the guide part 20 to the transition region 144, wherein the sensor unit 72 adjoins said transition region 144 at the front, free end 152.

[0273] At the front, free end 152, the sensor unit 72 has a sensor region opening 154 with a smaller opening height (not explicitly denoted) than a guide path opening 156 of the guide path 26.

[0274] In this case, the sensor region opening 154 has a width 158 which is greater than the width 160 of the guide path 26.

[0275] Furthermore, the clean region 134 is configured wider on its side 164 facing away from the sensor region 162 than on its side 166 facing the sensor region 162.

[0276] According to the depictions in FIGS. 9 to 12, the release unit 35 is illustrated again in more detail in combination with the holder 30 of the axially movable arm element.

[0277] As can already be seen in FIG. 8, the release unit 35 is arranged in the transition region 144 at an axial height between the sensor region 162 and the clean region 134.

[0278] The release unit 35 has stripping means 170, which are designed such that they only have a stripping or releasing effect on the sample carrier 3 in the axial retraction direction 23 (see particularly FIGS. 10 to 12), so that only a used sample carrier 3 is released from the holder 30 when the axially movable arm element 20 is moved through the release unit 35 in the axial retraction direction 23.

[0279] For this purpose, the release unit 35 has a main part 172 that can be penetrated by the axially movable arm element 20.

[0280] In this case, the main part 172 has a room height 174 which in this embodiment is more than 10 mm.

[0281] In any case, the room height 174 is many times greater than the arm element thickness 176.

[0282] In this embodiment, the stripping means 170 of the release unit 35 are designed as a first finger element 178 on the upper side 84 of the axially movable arm element 20 and as a lower flexible finger element 180 on the underside 85 of the axially movable arm element 20.

[0283] Both flexible finger elements 178 and 180 are two-part finger elements.

[0284] In other words, each of the flexible finger elements 178, 180 has two flexible finger parts 184 spaced apart from one another by a gap 182 (denoted only by way of example).

[0285] For this purpose, the gap 182 is selected such that the activation means 38 can easily pass through it, so that the activation means 38 do not influence the task of the release unit 35, but only serve to activate the feeding device 4 already described in detail above.

[0286] In addition, it is advantageous that the flexible finger parts 184 can adapt to, or flexibly follow, the existing contours of the axially movable arm element 20, so that the actual holder 30 configured on the axially movable arm element 20 can pass said release unit 35 without any problems.

[0287] In this respect, the release unit 35, in the sense of the invention, only interacts with a used sample carrier 3, so that it is released from the holder 30 of the axially movable arm element 20 when the axially movable arm element 20 with the holder 30 is moved through the release unit 35 in the axial retraction direction 23.

[0288] Only then is the used sample carrier 3 released from the holder 30 by means of the flexible finger parts 184, and the used sample carrier 3 falls into the toilet bowl 12 (see FIGS. 14 and 15) according to the disposal direction 186 (see FIG. 12), so that it can be easily disposed of via the toilet 13.

[0289] The alternative holder 190 shown in FIG. 13 has a fastener 191 with a fastening body 192, by means of which the holder 190 can be fixed on the movable arm element 20. For this purpose, it is sufficient to simply slide the holder 190 onto the movable arm element 20 with a mounting force, wherein the mounting force is substantially greater than all other working forces acting on the holder 190 during normal operation of the device 1. As a result, the holder 190 sits operationally safe on the movable arm element 20.

[0290] The holder 190 has a clamping element 193 which is rotatably mounted on the fastening body 192 by means of a spring-pretensioned axis of rotation 194.

[0291] In this case, the holder 190 functions essentially similarly to a spring-pretensioned folding mechanism.

[0292] Basically, the clamping element 193 is moved in the clamping direction 195 by the spring forces of the spring-pretensioned axis of rotation 194, so that a sample carrier 3 is clamped operationally safe between the movable arm element 20 and the clamping element 193.

[0293] The holder 190 is opened by moving the movable arm element 20 in the retraction direction 23 and pressing the end 197 of the clamping element 193 facing away from the clamping side 196 against a resistance (not depicted), resulting in an opening force 198 acting on said end 197.

[0294] Said resistance is normally located on the feeding device 4 because this is where the holder 190 is also supposed to be opened for receiving a new sample carrier 3.

[0295] The resistance can be realized by a mechanical forced guidance or other mechanical elements, which can be arranged along the movable arm element 20 preferably in an adjustable manner. In this way, the position, at which the holder 190 is finally opened in order to receive a new sample carrier 3, or lets go of a used sample carrier 3 and releases it from the holder 190, can be clearly determined.

[0296] According to the depiction in FIG. 14, the present device 1 is suspended from the edge 11 of the toilet bowl 12. For this purpose, the axially movable arm element 20 has already been extended, particularly from the guide part 25, into the toilet bowl 12, wherein a new sample carrier 3 is placed inside the toilet bowl 12 such that the sample carrier 3 is well placed on the toilet 13 for receiving particularly urine.

[0297] According to the further depiction in FIG. 15, it is shown again in somewhat more detail, how the device 1 is placed on the toilet bowl 12 by means of the retaining bracket 10.

[0298] According to the depictions in FIGS. 16 and 17, another sensor unit 210 with a transmitted light apparatus 211 is also shown, wherein particularly the device 1 described above can also be equipped cumulatively or alternatively with said other sensor unit 210.

[0299] By means of said other sensor unit 210, it is possible to not only illuminate a sample carrier 215 from one side, for example, in the sense of reflection photometry, but to also completely or partially transilluminate a correspondingly designed sample carrier 215.

[0300] For this purpose, the sample carrier 215 has a translucent main part 216 and translucent sample analysis fields 217 (denoted only by way of example), wherein said translucent sample analysis fields 217 can also be equipped with different indicators 218 and 219 for different analyses (only denoted by way of example, cf. FIGS. 17 and 21).

[0301] The transmitted light measuring apparatus 211 is arranged at least partially on both sides of the sample carrier 215.

[0302] More precisely, the transmitted light measuring apparatus 211 is at least partially arranged on both sides of a transport path 220, wherein the transport path 220 is an integral component of the transmitted light measuring apparatus 211, along which the sample carrier 215 can be moved.

[0303] In particular, the transmitted light apparatus 211 in this embodiment has an illumination device 225 on a first side 226 of the integral transport path 220, and a detection device 230 on a second side 231 of the integral transport path 220 which lies opposite the first side 226.

[0304] In this case, the illumination device 225 has three light sources 233, 234, and 235 with respective main beam paths 236 (denoted only by way of example), wherein the light sources 233, 234, and 235 are herein designed as LEDs.

[0305] The detection device 230 is characterized by at least one detection sensor surface 240, which in this embodiment is arranged with its detection side 241 facing the light sources 233, 234, and 235.

[0306] The transmitted light measuring apparatus 211 thus has more than one light source 233, 234, 235, wherein the main beam path 236 of the light sources 234 is arranged to run at a right angle to the detection sensor surface 240, and the main beam paths 236 of the further light sources 233 and 235 are arranged to run at a different angle 242 to the detection sensor surface 240.

[0307] The other sensor unit 210 can be equipped with a simple housing 245 consisting at least partially of the guide part 25 of the device, as can be seen in FIG. 17.

[0308] According to the depiction in FIG. 18, the sensor unit 210 shown in FIGS. 16 and 17 is equipped with the transmitted light measuring apparatus 211 and also has two additional light sources 245 and 246, which are arranged on the same side of the integral transport path 220 as the detection device 230, namely the second side 231.

[0309] By means of the two additional light sources 245 and 246, sample analysis fields 249 of the alternative sample carrier 250 introduced into the sensor unit 210 can either be additionally transilluminated or illuminated in a reflective manner.

[0310] On the alternative sample carrier 250, the sample analysis fields 249 are arranged on both sides of its main part 251 (denoted only by way of example), namely a single sample analysis field 249 on its front side 252, and two sample analysis fields 249 on its rear side 253, so that, at an identical sample carrier size, more sample analysis fields 249 can be accommodated on the alternative sample carrier 250.

[0311] According to the depiction in FIG. 19, another sample carrier 260 is shown, on the front side 262 of which round sample analysis fields 265 of different sizes (only denoted by way of example) with different indicator materials 266 (only denoted by way of example) are placed.

[0312] FIG. 20 shows a side view of the sample carrier 250 from FIG. 18.

[0313] FIG. 21 shows a further alternative sample carrier 270. The further alternative sample carrier 270 has a main part 271, on the front 272 of which two sample analysis fields 279 of different sizes are placed, and on the rear 273 of which a single sample analysis field 279 is placed.

[0314] At this point, it must be explicitly pointed out that features of the solutions described above or in the claims and/or the drawings can also be combined, if appropriate, in order to be able to implement or achieve the described features, effects, and advantages in a correspondingly cumulative manner.

[0315] It goes without saying that the embodiment described above is merely a first embodiment of the device according to the invention. In this respect, the design of the invention is not limited to said embodiment.

[0316] All of the features disclosed in the application documents are claimed to be essential to the invention, provided that, individually or in combination with one another, they are novel over the prior art.
