  • This sensor is inexpensive and is adapted for quick and convenient disposal and replacement, thus eliminating the inconvenience of cleaning and sanitizing. Because of its small transverse dimensions, elongated shape and the soft outer covering, the sensor is very comfortable to wear.
  • a connector is detachably secured to one end of the sensor to. provide electrical connection to a high input impedance signaling circuit that operates on very low power with almost no current flow between the conductors whenshorted by the conductive fluid.
  • a moisture detector is provided for sensing and indicating the flow in a specified region.
  • The'sensor consists of two closely spaced elongated conductors, each surrounded by an elongated 'po-rous tube providing in-. sulation between the conductors until thepresence of fluid on the sensor electrically shorts the two conductors together.

  • FIG. 1 shows a preferred form of moisturesensor 10 which includes two electrical conductors l2 and 14 encased in an elongated tube of woven or matted material having its two walls longitudinally stitched or crimped together at l6forming an enclosure 18 and 20 surrounding each of the conductors 12 and 14 respectively.
  • the stitching 16 electrically isolates the two conductors from each other until an electrically conductive fluid, such as urine, closes the gap between them forming an electrical connection'or short through the woven material across stitching l6.
  • Sensor 10 is preferably constructed with its largest transverse dimension.
  • the conductors 12 and 14 are composed of metal wires, such as stainless steel, that do not rapidly deteriorate or react with the fluids encountered.
  • the desired length of sensor 10 may be easily cut from a roll with a scissors or the like when it is time to replace a wetted length with a clean, dry length of sensor. Because of its elongated configuration-and small transverse dimensions, the sensor positioned in or near a users crotch will tend to work into the crotch area and automatically remain in position during the wear-- ers movements.
  • the thin tubular construction and soft outer covering provide a sensor which is extremely comfortable when in position.
  • the sensor may alternativelyv be secured to either the user or his clothing with clips, a strip of adhesive or the like along one side of the seam I6;
  • the senor 10 When the sensor 10 becomes saturated with fluid,'or at any other appropriate time, the sensor may be removed an replaced by another clean length thus avoiding time-consuming and expensive d'isassembly, cleaning and sanitizing of the sensor assembly.
  • the disposable and replaceable feature of this sensor is made possible by its inexpensive and simple construction and the detachable connector to be described.
  • Connector 22 shown in FIG. 2, electrically connects the conductors 12 and 14 to the signaling circuit (FIGS. 4 and 5) and display clip 52 shown in FIG. 3.
  • the end of sensor fits into a recess 26 to position each conductor 12 and 14 over one of two parallel spaced spiked metal rails 28 that are fixed on the upper surface of recess 26 in connector base 24.
  • the spikes extend upward to pierce the ends of the sensor tubes 18 and 20 inserted in recess 26 upon closing a hinged connector cover 30.
  • Contact bars 32 carried on the underside of cover are positioned to mate with the spiked rails 28 and force the sensortubes 18 and 20 downward onto the spikes that penetrate the tube fabric to make electrical contact with conductors l2 and 14 while mechanically gripping and holding the sensor.
  • a central bar 36 presses against the stitching 16 to insure electrical isolation between the conductors.
  • the connector body 24 and the cover 30 with contact bars 32 and 36 are both integrally moled of an insulating material, such as hard plastic or the like.
  • An integral thin flexible strip 34 composed of the same plastic material, can hinge the base 24 and cover 30 together thus permitting an integral connector unit 22.
  • Bars 32 and 36 are formed with inward facing undercut projections 38 arranged to engage mating notches 40 formed in the inner wall of recess 26 to secure the cover and base together when the cover is closed.
  • the flexible strip hinge 34 permits a slight outward movement of the cover 30 on closure so that the projections 38 slide forward in clearing the recess wall and are then pulled back into the notches 40.
  • the cover can be reopened by simply prying upward with a thumbnail between the cover and base.
  • recesses 42 formed in base 24 receive batteries which will be part of the electrical circuit described hereinafter.
  • connector base 24 may house the electrical circuit components which are electrically connected to the underside of the rails 28.
  • Aperture 44 in the rear corner of the base provides access for leads 46 and 48 to connect the electrical components deployed in the connector with display clip 52 shown in FlG. 3.
  • Connector22 may be secured to'a users clothing or to an adjacent location by means of a clip, adhesive, or the like (not shown) applied to the underside of the base 24.
  • Electrical leads 46 and 48 from connector 22 pass through aperture 56 of relatively flat, thin display clip.
  • Lead 48 and wire 59 provide electrical connection through light emitting diode 58.
  • Stop 64 electrically connected to the other lead 46, provides part of a normally open switch that closes to allow current flow through light emitting diode 58'to indicate a short across conductors 12 and 14. This switch is closed by moving wiper 62 across electrode rail 60 thathas one end electrically connected to diode 58 by wire 59, until contact is made with stop 64.
  • Wiper 62 is an extension of spring 66 mounted in the central portion of clip 52 and held in position by threaded retaining screw 68 which screws into the clip body.
  • Spring 66 biases wiper arm 62 in a position normally spaced from stop 64 so that no indication of a short between conductors 12 and 14 will occur until a person checking for that condition pushes wiper 62 across electrode 60 against stop 64.
  • the wiper springs back into a position spaced from stop 64 upon being released.
  • Spring 66, wiper 62, electrode 60 and stop 64 are all composed of an electrically conductive material, such as stainless steel or the like.
  • Display clip 52 may be secured to the clothing of the user, to a wall, or to some other convenient place by means of a fastener, adhesive or the like (not shown) applied to the back of the clip.
  • one form of sensing circuit that may be employed consists of a simple transistor switching arrangement.
  • the open circuit maintained in the absence of fluid shorting the conductors l2 and 14 results in the base of transistor 80, which is connected to the negative terminal of battery 84 through resistor 88, being held at that negative potential to cut off the cascade connected transistors and 82.
  • no current can flow through the light emitting diode 58 although the switch arm 62 is closed on stop 64.
  • circuit through resistors 86 and 88 is closed across battery 84 to produce a positive bias on the base of transistor 80 to render it conductive. thus driving the base of transistor 82 positive.
  • switch arm 62 If switch arm 62 is closed, transistor 82 switches to saturation causing current to flow through the light emitting diode 58. Thus, the circuit does not provide actuating current through the diode 58 unless an electrically conductive fluid shorts the conductors 12 and 14 while switch arm 62 is closed against stop 64. In this manner, battery 84 is conserved since current can flow only when the switch is closed to check for the presence of fluid.
  • a current flow of only a fraction of a microampere or less can be maintained through conductors l2 and 14 for the users safety and to increase the life of the battery power supply by selecting resistors 86 and 88 to have relatively large impedances, such as 18 and 22 megohms respectively, while battery 84 has a relatively low voltage, such as 2.8 volts.
  • each sensor may be connected to a separate display device, such as light emitting diode 58, mounted in an adjacent wall receptacle or more conveniently on a central patientcall board, which might also employ other types of indicators, such as an audible bell or buzzer, to attract the attention of the attendant.
  • the sensing circuit might be used to trigger a radio transmitter to actuate an appropriate signal or other indicator at some remote centralstation.
  • the normally open circuit between the sensor conductors 12 and 14 maintains a positive bias on gate terminal 94 to permit low impedance conduction between the source 96"and drain 98 terminals of field effect transistor (FET) 100.
  • FET field effect transistor
  • the drain terminal 98 of the FET 100 is coupled to the common point between series connected resistors 112 and 114, which are also in series with input resistor 116, thus forming a three part voltage divider across the battery 110.
  • the relative values of the resistors 112, 114 and 116 typically 7.5, 56.0 and about l0 kilohms or less, respectively, are selected to develop a forward bias potential across input resistor 116 when the FET 100 is cutoff in a non-conductive state, sufficient to cause switching transistor 108 to conduct in saturation.
  • the FET 100 is initially placed in its conductive state by temporarily connecting two reset terminals 118 and 120, which may simply be two adjacent exposed contact surfaces that can be spanned by touch ing a fingertip to the area. Since the reset terminal 118 is directly coupled to the positive terminal on the battery 110, this potential is thus applied on reset to the gate terminal 94 of the FET 100 to render it conductive.
  • the FET source terminal 96 is coupled to the common point between a pair of' other voltage divider resistors 122 and 124 connected across the battery 110.
  • the values for the resistors 122 and 124 are substantially less than those employed in the other'voltage divider arrangement consisting of the resistors 112, 114 and 116. Also the resistor 122 connected to the positive battery terminal is several times larger than that of the resistor 124 to provide a significantly lower or more negative potential at the source 96. Accordingly, when the FET 100 is cutoff, the higher voltage between the resistors 112 and 114 is present at the drain terminal 98 to hold the field effect transistor 100 in its forward biased state relative to the lower potentialon the source terminal 96.
  • a very high impedance resistor 126 is placed in series between the sensor conductors 12 and 14 and the FET gate' terminal 94 and is further coupled through a small capacitor 128. typically about 0.01 microfarads, to the positive terminal of the battery llO.
  • a small capacitor 128 typically about 0.01 microfarads
  • the attendant may then merely touch exposed contacts 118 and 120 to reset the circuit by discharging the negative charge on the capacitor l28 and leaving a positive charge that holds FET conducting and transistor I08 cutoff until the sensor conductors 112 and H4 are again shorted together by a conductive fluid.
