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. 1 is a schematic representation of a transducer of the device according to the invention
  • FIG. 2a-c the schematic representation of the transducer from FIG. 1 in three different swelling states of the penis
  • 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
  • the thick measuring loop 5 has a large spring coefficient c 2 .
  • Reference number 6 designates the measuring connections with which the two measuring loops 4 and 5 are connected to a resistance measuring device.
  • 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.
  • 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.
  • 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.

Abstract

Ce dispositif pour déterminer la tumescence et la rigidité d'un pénis comprend un capteur de valeurs de mesure (1) avec une boucle de mesure annulaire (4) que l'on peut poser autour d'un pénis avant érection (3) et qui lorsque le pénis se gonfle (3) peut s'étirer contre une force de rappel déterminée, le capteur de valeurs de mesure (1) émettant un signal de mesure représentatif de l'extension de la boucle. Les dispositifs connus comprennent une boucle non élastique de mesure de la tumescence qui est serrée avec une force prédéterminée à des intervalles prédéterminés afin de déterminer la rigidité du pénis sur la base de sa constriction. Afin d'éliminer la commande complexe des deux opérations différentes de mesure, le capteur (1) de valeurs de mesure de la rigidité comprend une deuxième boucle de mesure (5) située à côté de la première boucle de mesure (4) et qui peut s'étirer contre une force de rappel supérieure à la force de rappel de la première boucle de mesure (4).
