Definitions
- the invention relates to a device for determining the tumescence and rigidity of a penis, with a transducer which has a ring-like measuring loop which can be placed around the unguented penis and stretchable against a certain restoring force when the penis swells, the transducer representing a measurement signal representing the elongation delivers.
- the measuring loop is formed by an inextensible band, which is pulled tight around the penis by a low spring force.
- the tumescence is determined by measuring the length of the band section enclosing the penis.
- a torque motor exerts an increased tensile force on the band so that it is pulled more tightly around the penis.
- the change in length during this process can determine the internal pressure that causes the penis to swell.
- the rigidity of the penis can thus be determined.
- Control means are provided which are electrically connected to the measuring sensor formed by the band and which control the switching back and forth between the rigidity measurement on the one hand and the tumescence measurement on the other hand and the differentiation of the signals which on the one hand correspond to the rigidity and on the other hand the tumescence.
- the device disclosed in the cited documents comprises two measuring sensors, each formed by a band, which on the one hand has a root on the penis and, on the other hand, measures the rigidity and tumescence in the vicinity of the glans.
- the object of the invention is to provide a device in which the complex control of the recording of the two different measured values can be dispensed with.
- the transducer has a second measuring loop which is arranged next to the first measuring loop and which is stretchable against a restoring force which is greater than the restoring force of the first measuring loop.
- This second measuring loop which opposes the swelling of the penis with a considerably greater force, is used for permanent rigidity measurement.
- ERSATZBL ⁇ 1T (RULE 26) Penis can be viewed as a one-sided open and stretchable hydraulic vessel, which has a maximum stretchability. Blood flows into the erectile tissue at a certain blood pressure through the unilateral opening. In this process, the first measuring loop with the low restoring force is rapidly stretched with increasing blood pressure until the erectile tissue reaches its maximum diameter. In this state, the layers of tissue surrounding the erectile tissue of the penis prevent further expansion of the penis. The first measuring loop is therefore used for the permanent measurement of the tumescence of the penis. The second measuring loop with the increased restoring force is only extended to the maximum circumference of the penis when the internal pressure inside the erectile tissue is extremely high. Due to the known restoring force and the measurable elongation of the second measuring loop, the rigidity of the penis can be determined permanently with this measuring loop.
- the two restoring forces of the measuring loops are chosen so that the restoring force of the first measuring loop only counteracts a slight force against the swelling of the penis, whereas the restoring force of the second measuring loop prevents a complete swelling of the penis.
- the first measuring loop reliably measures the swelling (tumescence) of the penis regardless of the swelling force and the second measuring loop the rigidity of the penis by determining the radially outward pressure within the penile body, which is based on the known restoring force and the known elongation the second measuring loop can be determined. If the restoring force of the second measuring loop is too small, the sensor has a limited measuring range, which ends below the maximum rigidity of the penis.
- the two measuring loops are preferably formed from an electrically conductive, elastic material, the electrical resistance of which changes as a function of the material elongation.
- An electrically conductive silicone more precisely a silicone elastomer, in the silicone elastomer base of which carbon particles are mixed, has proven to be particularly suitable for the production of the measuring loops. These silicone loops can be used to produce an extremely cost-effective sensor, which can be provided for single use for hygiene reasons.
- the silicone elastomer has the material properties of a Spring, which generates a restoring force that increases linearly over the lengthening with a fixed spring constant.
- the measuring loops for insulation are preferably surrounded by an electrically non-conductive material layer.
- This measure initially has the advantage that the measurement results are not falsified by secondary currents of the measuring current which are introduced into the tissue of the penis via the skin.
- the insulation prevents diffusion of the carbon particles from the silicone elastomer into human tissue, which could cause allergic reactions.
- two sensors are preferably used, which perform a tumescence and rigidity measurement, one in the area of the penis root and one in the vicinity of the glans.
- elongated measuring strips can be arranged between these transducers, which are stretchable in the longitudinal direction against a restoring force and emit a signal representing the elongation.
- Preferably three measuring strips are arranged at the most uniform angular intervals possible along a generatrix of the penis. Due to the elongation of the three measuring strips during the tumescence event (swelling of the penis), possible curvatures of the penis can be determined.
- the measuring strips also preferably consist of carbon-containing silicone elastomer.
- the measurement with the measuring loops or measuring strips of the described device is carried out simply by connecting a resistance measuring device which determines the resistance by feeding a small current into the two ends of the measuring loop or the measuring strip.
- the measured value determined can be converted directly into the elongation of the measuring loop or the measuring strip and, if necessary, the radial tension force of the measuring loop.

- FIG. 3 the top view of a penis with the preferred embodiment of the measuring device according to the invention with two transducers
- the transducer 1 shows a transducer 1 of a device according to the invention, which is arranged in the vicinity of the glans 2 of a penis 3.
- the transducer 1 comprises a thin measuring loop 4 and a thick measuring loop 5.
- Both measuring loops 4, 5 consist of electrically conductive silicone elastomer, in which carbon particles are embedded.
- the thin measuring loop 4 has a small spring coefficient c

- 2a-c show the measuring principle of the transducer with the two measuring loops 4 and 5.
- 2a shows the penis 3 in a relaxed state. There is only a slight pressure inside the erectile tissue. Due to the increased restoring force of the thick measuring loop 5, the latter has a small diameter s 2 , whereas the diameter s of the thin measuring loop 4 is somewhat larger. Since the pressure within the cavernous body exerts the same force on both measuring loops 4 and 5, the product of the change in the circumferential length of the two measuring loops 4, 5 is identical with the respective spring constant c or c 2 of the two measuring loops 4, 5. In this state, both the tumescence and the rigidity of the penis 3 can be determined with the measuring loop 4.
- the tumescence (swelling) can be calculated from the elongation of the measuring loop 4, which represents the measured resistance value.
- Rigidity (stiffness) is the measure of the internal pressure in the erectile tissue, which results from the elasticity (product of the Elongation with the spring stiffness c,) of the measuring loop 4 can be determined. Alternatively, the rigidity can be determined in this state with the measuring loop 5.
- the second measuring loop 5 is still able to constrict the penis 3 slightly, so that further measurements of the radially outward forces of the erectile tissue are possible.
- the radial forces within the erectile tissue can be clearly assigned to the respective resistance within the measuring loop 5, ideally there being a linear relationship between the resistance value and the circumferential change in length of the measuring loop 5.
- the measuring loop 4, on the other hand, has reached a size corresponding to the maximum penis size, so that it no longer provides values that can be used to determine the rigidity.
- the tumescence is 100%.
- FIG. 2c shows a penis 3 with the measuring transducer according to the invention described in a fully erect state.
- the thick measuring loop 5 no longer constricts the penis 3. This should only occur exceptionally with a particularly high rigidity in a transducer according to the present invention.

- Fig. 3 shows a device according to the invention, in which two sensors 1 are provided, similar to the device from the above-mentioned prior art, namely one near the glans and the second in the penis root.
- FIG. 4 and 5 show the top view of an advantageous embodiment of the invention.
- the transducers 1 are connected to one another with three measuring strips 7, which enable the penis curvature to be measured.
- the measuring strips 7 should preferably run at an angular distance of 120 ° in each case along a generatrix of the penis 3.
- FIG. 4 shows a penis 3 which in the erect state runs essentially straight.
- the lengths of the three measuring strips 7 are essentially the same, so that all three measuring strips 7 have an essentially identical resistance value.
- Fig. 5 there is a penis curvature, which leads to the fact that the measuring strip 7 shown in Fig. 5 below is less stretched than the measuring strip 7 shown above.

Vorrichtung zum Messen der Tumeszenz und RigiditätDevice for measuring tumescence and rigidity
Die Erfindung betrifft eine Vorrichtung zur Ermittlung der Tumeszenz und Rigidität eines Penis, mit einem Meßwertaufnehmer, der eine ringartige Meßschlaufe aufweist, welche um den unerigierten Penis legbar und beim Anschwellen des Penis entgegen einer bestimmten Rückstellkraft dehnbar ist, wobei der Meßwertaufnehmer ein die Dehnung repräsentierendes Meßsignal abgibt.The invention relates to a device for determining the tumescence and rigidity of a penis, with a transducer which has a ring-like measuring loop which can be placed around the unguented penis and stretchable against a certain restoring force when the penis swells, the transducer representing a measurement signal representing the elongation delivers.
Derartige Vorrichtungen sind beispielsweise bekannt aus der EP 149 627 Bl und dem hiermit korrespondierenden US-Patent 4,515,166. Dabei wird die Meßschlaufe von einem undehnbaren Band gebildet, welches durch eine geringe Federkraft eng um den Penis gezogen wird. Durch Messung der Länge des den Penis umschließenden Bandabschnittes wird die Tumeszenz ermittelt. Zu bestimmten Zeitpunkten übt ein Drehmomentmotor eine erhöhte Zugkraft auf das Band aus, so daß es enger um den Penis gezogen wird. Durch die bei diesem Vorgang entstehende Längenänderung kann der Innendruck ermittelt werden, welcher den Penis zum Anschwellen bringt. Somit ist die Rigidität des Penis feststellbar. Steuermittel sind vorgesehen, welche elektrisch mit dem durch das Band gebildeten Meßwertaufnehmer verbunden sind und welche das Hin- und Herschalten zwischen der Rigiditätsmessung einerseits und der Tumeszenzmessung andererseits steuern sowie die Unterscheidung der Signale, die einerseits der Rigidität und andererseits der Tumeszenz entsprechen, bewirken. Die in den genannten Schriften offenbarte Vorrichtung umfaßt zwei durch jeweils ein Band gebildete Meßwertaufnehmer, welche einerseits an der Penis wurzel und andererseits in der Nähe der Glans die Rigidität und Tumeszenz messen.Such devices are known, for example, from EP 149 627 B1 and the corresponding US Pat. No. 4,515,166. The measuring loop is formed by an inextensible band, which is pulled tight around the penis by a low spring force. The tumescence is determined by measuring the length of the band section enclosing the penis. At certain times, a torque motor exerts an increased tensile force on the band so that it is pulled more tightly around the penis. The change in length during this process can determine the internal pressure that causes the penis to swell. The rigidity of the penis can thus be determined. Control means are provided which are electrically connected to the measuring sensor formed by the band and which control the switching back and forth between the rigidity measurement on the one hand and the tumescence measurement on the other hand and the differentiation of the signals which on the one hand correspond to the rigidity and on the other hand the tumescence. The device disclosed in the cited documents comprises two measuring sensors, each formed by a band, which on the one hand has a root on the penis and, on the other hand, measures the rigidity and tumescence in the vicinity of the glans.
Aufgabe der Erfindung ist es, eine Vorrichtung zu schaffen, bei der die aufwendige Steuerung der Aufnahme der beiden unterschiedlichen Meßwerte entfallen kann.The object of the invention is to provide a device in which the complex control of the recording of the two different measured values can be dispensed with.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Meßwertaufnehmer eine zweite Meßschlaufe aufweist, welche neben der ersten Meßschlaufe angeordnet ist und die entgegen einer Rückstellkraft dehnbar ist, welche größer als die Rückstellkraft der ersten Meßschlaufe ist.This object is achieved in that the transducer has a second measuring loop which is arranged next to the first measuring loop and which is stretchable against a restoring force which is greater than the restoring force of the first measuring loop.
Diese zweite Meßschlaufe, welche dem Anschwellen des Penis eine erheblich größere Kraft entgegensetzt, dient der permanenten Rigiditätsmessung. Der Schwellkörper desThis second measuring loop, which opposes the swelling of the penis with a considerably greater force, is used for permanent rigidity measurement. The erectile tissue of the
ERSATZBLÄ1T (REGEL 26) Penis kann als einseitig offenes und dehnbares hydraulisches Gefäß betrachtet werden, welches eine maximale Dehnfähigkeit aufweist. Durch die einseitige Öffnung strömt Blut mit einem bestimmten Blutdruck in den Schwellkörper. Bei diesem Vorgang wird die erste Meßschlaufe mit der geringen Rückstellkraft bei ansteigendem Blutdruck schnell gedehnt, bis der Schwellkörper seinen maximalen Durchmesser erreicht. In diesem Zustand verhindern die den Schwellkörper des Penis umgebenden Gewebeschichten eine weitere Ausdehnung des Penis. Die erste Meßschlaufe dient daher der permanenten Messung der Tumeszenz des Penis. Die zweite Meßschlaufe mit der erhöhten Rückstellkraft wird erst bei außerordentlich hohem Innendruck innerhalb des Schwellkörpers auf den maximalen Umfang des Penis ausgedehnt. Aufgrund der bekannten Rückstellkraft und der meßbaren Dehnung der zweiten Meßschlaufe läßt sich mit dieser Meßschlaufe permanent die Rigidität des Penis ermitteln.ERSATZBLÄ1T (RULE 26) Penis can be viewed as a one-sided open and stretchable hydraulic vessel, which has a maximum stretchability. Blood flows into the erectile tissue at a certain blood pressure through the unilateral opening. In this process, the first measuring loop with the low restoring force is rapidly stretched with increasing blood pressure until the erectile tissue reaches its maximum diameter. In this state, the layers of tissue surrounding the erectile tissue of the penis prevent further expansion of the penis. The first measuring loop is therefore used for the permanent measurement of the tumescence of the penis. The second measuring loop with the increased restoring force is only extended to the maximum circumference of the penis when the internal pressure inside the erectile tissue is extremely high. Due to the known restoring force and the measurable elongation of the second measuring loop, the rigidity of the penis can be determined permanently with this measuring loop.
Optimalerweise werden die beiden Rückstellkräfte der Meßschlaufen so gewählt, daß die Rückstellkraft der ersten Meßschlaufe dem Anschwellen des Penis nur eine geringfügige Kraft entgegenstellt, wogegen die Rückstellkraft der zweiten Meßschlaufe ein vollständiges Anschwellen des Penis möglichst verhindert. Auf diese Weise mißt die erste Meßschlaufe zuverlässig die Anschwellung (Tumeszenz) des Penis unabhängig von der Schwellkraft und die zweite Meßschlaufe die Rigidität des Penis durch Ermittlung des radial nach außen wirkenden Drucks innerhalb des Schwellkörpers des Penis, welcher aus der bekannten Rückstellkraft und der bekannten Dehnung der zweiten Meßschlaufe ermittelt werden kann. Ist die Rückstellkraft der zweiten Meßschlaufe zu klein, so hat der Meßwertaufnehmer einen begrenzten Meßbereich, welcher unterhalb der maximalen Rigidität des Penis endet.Optimally, the two restoring forces of the measuring loops are chosen so that the restoring force of the first measuring loop only counteracts a slight force against the swelling of the penis, whereas the restoring force of the second measuring loop prevents a complete swelling of the penis. In this way, the first measuring loop reliably measures the swelling (tumescence) of the penis regardless of the swelling force and the second measuring loop the rigidity of the penis by determining the radially outward pressure within the penile body, which is based on the known restoring force and the known elongation the second measuring loop can be determined. If the restoring force of the second measuring loop is too small, the sensor has a limited measuring range, which ends below the maximum rigidity of the penis.
Vorzugsweise werden die beiden Meßschlaufen aus einem elektrisch leitenden, elastischen Material gebildet, dessen elektrischer Widerstand sich in Abhängigkeit von der Materialdehnung verändert. Ein elektrisch leitfähiges Silicon, genauer gesagt ein Siliconelastomer, in dessen Siliconelastomer-Grundmasse Kohlenstoffpartikel eingemischt sind, hat sich als besonders geeignet für die Herstellung der Meßschlaufen erwiesen. Mit diesen Siliconschlaufen läßt sich ein äußerst kostengünstiger Meßwertaufnehmer herstellen, der aus Hygienegründen zur einmaligen Verwendung vorgesehen sein kann.The two measuring loops are preferably formed from an electrically conductive, elastic material, the electrical resistance of which changes as a function of the material elongation. An electrically conductive silicone, more precisely a silicone elastomer, in the silicone elastomer base of which carbon particles are mixed, has proven to be particularly suitable for the production of the measuring loops. These silicone loops can be used to produce an extremely cost-effective sensor, which can be provided for single use for hygiene reasons.
Bei sorgsamer Verarbeitung des Siliconelastomers läßt sich ein nahezu lineares Verhältnis zwischen der Schlaufendehnung und dem elektrischen Widerstand der Siliconschlaufe erzielen. Das Siliconelastomer hat die Materialeigenschaften einer Feder, welche mit einer festen Federkonstanten eine über die Längung linear ansteigende Rückstellkraft erzeugt. Durch diese Materialeigenschaften läßt sich anhand der gemessenen Längung der zweiten Meßschlaufe zuverlässig der radial nach außen wirkende Druck innerhalb des Schwellkörpers des Penis ermitteln.With careful processing of the silicone elastomer, an almost linear relationship between the loop elongation and the electrical resistance of the silicone loop can be achieved. The silicone elastomer has the material properties of a Spring, which generates a restoring force that increases linearly over the lengthening with a fixed spring constant. By means of these material properties, the radially outward pressure within the erectile tissue of the penis can be reliably determined on the basis of the measured elongation of the second measuring loop.
Vorzugsweise sind die Meßschlaufen zur Isolierung mit einer elektrisch nicht leitenden Material schicht umgeben. Diese Maßnahme hat zunächst den Vorteil, daß die Meßergebnisse durch Nebenströme des Meßstroms, welche über die Haut in das Gewebe des Penis eingeleitet werden, nicht verfälscht werden. Darüber hinaus verhindert die Isolation eine Diffusion der Kohlenstoffpartikel aus dem Siliconelastomer in das menschliche Gewebe, welche allergische Reaktionen hervorrufen könnte.The measuring loops for insulation are preferably surrounded by an electrically non-conductive material layer. This measure initially has the advantage that the measurement results are not falsified by secondary currents of the measuring current which are introduced into the tissue of the penis via the skin. In addition, the insulation prevents diffusion of the carbon particles from the silicone elastomer into human tissue, which could cause allergic reactions.
Ahnlich dem bekannten Stand der Technik werden vorzugsweise zwei Meßwertaufnehmer verwendet, welche eine Tumeszenz- und Rigiditätsmessung einmal im Bereich der Peniswurzel und einmal in der Nähe der Glans durchführen.Similar to the known prior art, two sensors are preferably used, which perform a tumescence and rigidity measurement, one in the area of the penis root and one in the vicinity of the glans.
Bei dieser Verwendung zweier Meßwertaufnehmer können zwischen diesen Meßwertaufnehmern längliche Meßstreifen angeordnet werden, die entgegen einer Rückstellkraft in Längsrichtung dehnbar sind und ein die Dehnung repräsentierendes Signal abgeben. Vorzugsweise werden drei Meßstreifen in möglichst gleichmäßigen Winkelabständen entlang einer Mantellinie des Penis angeordnet. Aufgrund der Längungen der drei Meßstreifen während des Tumeszenzereignisses (Anschwellung des Penis) lassen sich eventuelle Krümmungen des Penis ermitteln. Auch die Meßstreifen bestehen vorzugsweise aus kohlenstoffhaltigem Siliconelastomer.When using two transducers, elongated measuring strips can be arranged between these transducers, which are stretchable in the longitudinal direction against a restoring force and emit a signal representing the elongation. Preferably three measuring strips are arranged at the most uniform angular intervals possible along a generatrix of the penis. Due to the elongation of the three measuring strips during the tumescence event (swelling of the penis), possible curvatures of the penis can be determined. The measuring strips also preferably consist of carbon-containing silicone elastomer.
Die Messung mit den Meßschlaufen oder Meßstreifen der beschriebenen Vorrichtung erfolgt einfach durch den Anschluß eines Widerstandsmeßgerätes, welches durch Einspeisung eines geringen Stroms in die beiden Enden der Meßschlaufe oder des Meßstreifens den Widerstand ermittelt. Aufgrund der Materialeigenschaften kann der ermittelte Meßwert direkt in die Dehnung der Meßschlaufe oder des Meßstreifens sowie ggf. die radiale Spannkraft der Meßschlaufe umgerechnet werden.The measurement with the measuring loops or measuring strips of the described device is carried out simply by connecting a resistance measuring device which determines the resistance by feeding a small current into the two ends of the measuring loop or the measuring strip. On the basis of the material properties, the measured value determined can be converted directly into the elongation of the measuring loop or the measuring strip and, if necessary, the radial tension force of the measuring loop.
Zur Überwachung der Tumeszenzereignisse während einer Meßperiode, üblicherweise während einer Nacht, sollte ein Aufnahmegerät vorgesehen sein, welches die Meßwerte des Widerstandsmeßgerätes entweder kontinuierlich oder in bestimmten Zeitabständen aufzeichnet. .Die Auswertung der aufgenommenen Meßwerte erfolgt mit den üblichen Mitteln der elektronischen Datenverarbeitung. Weitere Vorzüge der Erfindung ergeben sich aus der nachfolgenden Zeichnungsbeschreibung. Die Zeichnungen zeigen in:To monitor the tumescence events during a measuring period, usually during a night, a recording device should be provided which records the measured values of the resistance measuring device either continuously or at certain time intervals. The evaluation of the recorded measured values takes place with the usual means of electronic data processing. Further advantages of the invention result from the following description of the drawings. The drawings show in:

Die Fig. 1 zeigt einen Meßwertaufnehmer 1 einer erfindungsgemäßen Vorrichtung, welche in der Nähe der Glans 2 eines Penis 3 angeordnet ist. Der Meßwertaufnehmer 1 umfaßt eine dünne Meßschlaufe 4 und eine dicke Meßschlaufe 5. Beide Meßschlaufen 4,5 bestehen aus elektrisch leitfähigem Siliconelastomer, in welches Kohlenstoffpartikel eingelagert sind. Die dünne Meßschlaufe 4 hat einen kleine Federkoeffizienten c,, wogegen die dicke Meßschlaufe 5 einen großen Federkoeffizienten c2 hat. Bei Dehnung der dünnen Meßschlaufe 4 entsteht daher nur eine geringe Rückstellkraft und bei Dehnung der dicken Meßschlaufe 5 eine hohe Rückstellkraft. Mit dem Bezugszeichen 6 sind die Meßanschlüsse bezeichnet, mit welchen die beiden Meßschlaufen 4 und 5 an ein Widerstandsmeßgerät angeschlossen werden.1 shows a transducer 1 of a device according to the invention, which is arranged in the vicinity of the glans 2 of a penis 3. The transducer 1 comprises a thin measuring loop 4 and a thick measuring loop 5. Both measuring loops 4, 5 consist of electrically conductive silicone elastomer, in which carbon particles are embedded. The thin measuring loop 4 has a small spring coefficient c ,, whereas the thick measuring loop 5 has a large spring coefficient c 2 . When the thin measuring loop 4 is stretched there is therefore only a slight restoring force and when the thick measuring loop 5 is stretched a high restoring force is produced. Reference number 6 designates the measuring connections with which the two measuring loops 4 and 5 are connected to a resistance measuring device.
In den Fig. 2a - c ist das Meßprinzip des Meßwertaufnehmers mit den beiden Meßschlaufen 4 und 5 dargestellt. Dabei zeigt die Fig. 2a den Penis 3 in erschlafftem Zustand. Innerhalb des Schwellkörpers herrscht nur ein geringer Druck. Aufgrund der erhöhten Rückstellkraft der dicken Meßschlaufe 5 weist diese einen kleinen Durchmesser s2 auf, wogegen der Durchmesser s, der dünnen Meßschlaufe 4 etwas größer ist. Da der Druck innerhalb des Schwellkörpers auf beide Meßschlaufen 4 und 5 die gleiche Kraft ausübt, ist das Produkt der Änderung der Umfangslänge der beiden Meßschlaufen 4,5 mit der jeweiligen Federkonstanten c, bzw. c2 der beiden Meßschlaufen 4,5 identisch. In diesem Zustand lassen sich mit der Meßschlaufe 4 sowohl die Tumeszenz als auch die Rigidität des Penis 3 bestimmen. Die Tumeszenz (Anschwellung) läßt sich aus der Dehnung der Meßschlaufe 4 berechnen, die den gemessenen Widerstandswert repräsentiert. Die Rigidität (Steifigkeit) ist das Maß für den Innendruck in dem Schwellkörper, der sich aus der Spannkraft (Produkt der Dehnung mit der Federsteifigkeit c,) der Meßschlaufe 4 bestimmen läßt. Alternativ kann die Rigidität in diesem Zustand mit der Meßschlaufe 5 bestimmt werden.2a-c show the measuring principle of the transducer with the two measuring loops 4 and 5. 2a shows the penis 3 in a relaxed state. There is only a slight pressure inside the erectile tissue. Due to the increased restoring force of the thick measuring loop 5, the latter has a small diameter s 2 , whereas the diameter s of the thin measuring loop 4 is somewhat larger. Since the pressure within the cavernous body exerts the same force on both measuring loops 4 and 5, the product of the change in the circumferential length of the two measuring loops 4, 5 is identical with the respective spring constant c or c 2 of the two measuring loops 4, 5. In this state, both the tumescence and the rigidity of the penis 3 can be determined with the measuring loop 4. The tumescence (swelling) can be calculated from the elongation of the measuring loop 4, which represents the measured resistance value. Rigidity (stiffness) is the measure of the internal pressure in the erectile tissue, which results from the elasticity (product of the Elongation with the spring stiffness c,) of the measuring loop 4 can be determined. Alternatively, the rigidity can be determined in this state with the measuring loop 5.
In Fig. 2b ist ein Zustand dargestellt, in dem die radiale Kraft des Innendrucks des Schwellkörpers ausreicht, die dünne Meßschlaufe 4 soweit zu dehnen, daß der Penis 3 seinen maximalen Umfang erreicht. Die zweite Meßschlaufe 5 vermag immer noch, den Penis 3 leicht einzuschnüren, so daß weitere Messungen der radial nach außen wirkenden Kräfte des Schwellkörpers möglich sind. Die radialen Kräfte innerhalb des Schwellkörpers sind eindeutig dem jeweiligen Widerstand innerhalb der Meßschlaufe 5 zuzuordnen, wobei idealerweise ein linearer Zusammenhang zwischen dem Widerstandwert und der umfangsmäßigen Längenänderung der Meßschlaufe 5 besteht. Die Meßschlaufe 4 hat dagegen einen dem maximalen Penisumfang entsprechenden Umfang erreicht, so daß sie keine für die Bestimmung der Rigidität verwendbaren Werte mehr liefert. Die Tumeszenz beträgt 100 % .2b shows a state in which the radial force of the internal pressure of the erectile tissue is sufficient to stretch the thin measuring loop 4 to such an extent that the penis 3 reaches its maximum circumference. The second measuring loop 5 is still able to constrict the penis 3 slightly, so that further measurements of the radially outward forces of the erectile tissue are possible. The radial forces within the erectile tissue can be clearly assigned to the respective resistance within the measuring loop 5, ideally there being a linear relationship between the resistance value and the circumferential change in length of the measuring loop 5. The measuring loop 4, on the other hand, has reached a size corresponding to the maximum penis size, so that it no longer provides values that can be used to determine the rigidity. The tumescence is 100%.
Die Fig. 2c zeigt einen Penis 3 mit dem beschriebenen erfindungsgemäßen Meßwertaufnehmer in vollständig erigiertem Zustand. Bei der vorliegenden Darstellung schnürt nun auch die dicke Meßschlaufe 5 den Penis 3 nicht mehr ein. Dies sollte bei einem Meßwertaufnehmer gemäß der vorliegenden Erfindung nur ausnahmsweise bei besonders hoher Rigidität eintreten. Bei normalen Patienten sollte die Federkonstante der Meßschlaufe 5 derart gewählt sein, daß sie selbst bei maximaler Rigidität den Penis noch leicht einschnürt, um zuverlässige Messungen in allen Erektionszuständen zu gewährleisten.2c shows a penis 3 with the measuring transducer according to the invention described in a fully erect state. In the present illustration, the thick measuring loop 5 no longer constricts the penis 3. This should only occur exceptionally with a particularly high rigidity in a transducer according to the present invention. In normal patients, the spring constant of the measuring loop 5 should be selected such that it still constricts the penis slightly, even with maximum rigidity, in order to ensure reliable measurements in all erection states.
Die Fig. 3 zeigt eine erfindungsgemäße Vorrichtung, bei der ähnlich der Vorrichtung aus dem oben genannten Stand der Technik zwei Meßwertaufnehmer 1 vorgesehen sind, nämlich einer in der Nähe der Glans und der zweite in der Penis wurzel.Fig. 3 shows a device according to the invention, in which two sensors 1 are provided, similar to the device from the above-mentioned prior art, namely one near the glans and the second in the penis root.
Die Fig. 4 und 5 zeigen die Draufsicht auf eine vorteilhafte Ausführungsform der Erfindung. Dabei sind die Meßwertaufnehmer 1 untereinander mit drei Meßstreifen 7 verbunden, welche eine Messung der Peniskrümmung ermöglichen. Die Meßstreifen 7 sollten möglichst im Winkelabstand von 120° jeweils entlang einer Mantellinie des Penis 3 verlaufen. Die Fig. 4 zeigt einen Penis 3, der in erigiertem Zustand im wesentlichen gerade verläuft. Hier sind die Längen der drei Meßstreifen 7 im wesentlichen gleich, so daß alle drei Meßstreifen 7 einen im wesentlichen übereinstimmenden Widerstandswert haben. In Fig. 5 ergibt sich eine Peniskrümmung, welche dazu führt, daß der in Fig. 5 unten dargestellte Meßstreifen 7 weniger gedehnt ist als der oben dargestellte Meßstreifen 7. Es ergeben sich unterschiedliche Widerstandswerte für die Meßstreifen 7, so daß exakt die räumliche Krümmung des Penis 3 ermittelt werden kann.4 and 5 show the top view of an advantageous embodiment of the invention. The transducers 1 are connected to one another with three measuring strips 7, which enable the penis curvature to be measured. The measuring strips 7 should preferably run at an angular distance of 120 ° in each case along a generatrix of the penis 3. FIG. 4 shows a penis 3 which in the erect state runs essentially straight. Here the lengths of the three measuring strips 7 are essentially the same, so that all three measuring strips 7 have an essentially identical resistance value. In Fig. 5 there is a penis curvature, which leads to the fact that the measuring strip 7 shown in Fig. 5 below is less stretched than the measuring strip 7 shown above. There are different resistance values for the measuring strips 7, so that exactly the spatial curvature of the Penis 3 can be determined.
