Description

    CROSS REFERENCE TO RELATED APPLICATIONS
  • This application is a divisional application of U.S. Ser. No. 13/391,387, filed Apr. 17, 2012, which claims the benefit of U.S. Provisional Application No. 61/235,725, filed 21 Aug. 2009 and U.S. Provisional Application 61/349,897, filed 31 May 2010, the contents of which are incorporated herein by reference thereto.
  • COPYRIGHT & LEGAL NOTICE
  • A portion of the disclosure of this patent document contains material which is subject to to copyright protection. The copyright owner has no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure as it appears in the Patent and Trademark Office patent file or records, but otherwise reserves all copyright rights whatsoever. Further, no reference to third party patents or articles made herein is to be construed as an admission that the present invention is not entitled to antedate such material by virtue of prior invention,
  • BACKGROUND OF THE INVENTION
  • This invention relates to indicators and in particular analog visual indicators used to dispense a measured amount of liquid.
  • Analog indicators have existed since time immemorial. The hour glass, for example, uses sand or fluid which, influenced by the weight of gravity, moves from one reservoir to another by passing through a small aperture therebetween. Another example of an ancient analog indicator is the “Clepsydra”, as illustrated in “Horloges Anciennes” by Richard Mühe and Horand M. Vogel, French Edition, Office du Livre, Fribourg, 1978, page 9.
  • Referring to FIG. 1, U.S. Pat. No. 3,783,598 describes an instrument 1 having a movement 2, a drive shaft 3, cams 4, pistons 5, fluid filled capillaries 6 and a relief chamber 7 used to indicate time. Automated fluid dosage devices exist. A typical insulin pump is a computerized device that looks like a pager and is usually worn on the patient's waistband or belt. The pump is programmed to deliver small, steady doses of insulin throughout the day. Additional doses are given to cover food or high blood glucose levels. The pump holds a reservoir of insulin that is attached to a system of tubing called an infusion set. Most infusion sets are started with a guide needle, then the plastic cannula (a tiny, flexible plastic tube) is left in place, taped with dressing, and the needle is removed. The cannula is usually changed every 2 or 3 days or when blood glucose levels remain above target range. However, such devices are bulky and are not always located at a place on the body that is easy to access or read.
  • Referring to FIG. 2, a wrist worn device, such as the “GLUCOWATCH” is known. This prior art device, said to be developed in 2001, has a casing 8 supported on a bracelet 9. A reservoir dispenses insulin onto a patch similar to a transdermal medication patch used for smoking cessation and hormone therapy. It therefore provides a non-invasive, needle-free method of enhancing and controlling the transport of water-soluble ionic drugs out of the skin and surrounding tissues using a low level of electrical current.
  • These prior devices are cumbersome, requiring significant or dedicated space for indicating the value, lack accuracy or only are too costly for many users.
  • What is needed is a visual indicator that provides a quickly read indication of a measured dosage value and is inexpensive to manufacture.
  • SUMMARY OF THE INVENTION
  • A visual indicator display device includes a bracelet, a transparent capillary chamber, and a displacement member. The transparent capillary chamber is matched to an indicia and has a primary length and a width less than the primary length. The displacement member is functionally disposed at one end of the capillary chamber and is responsive to a measureable input for moving a fluid contained therein a defined amount.
  • An object of the invention is to provide a visual indicator which takes up minimal space.
  • Another object of the invention is to provide a flexible visual indicator which adapts to requirements which do not readily permit a straight, rigid indicator, such as when such indicator is worn on a wrist, ankles, a head or around or along some part of human body, or on objects such as clothes and sporting articles.
  • Another object of the invention is to provide an aesthetic, comfortable, reliable and intellectually attractive indicator.
  • Another object of the invention is to provide a dispenser of fluids such as drugs, medication, ointment, oils or perfumes.

  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • The following description is not intended to limit the scope of the invention in any way as they are exemplary in nature and serve, to describe the best mode of the invention known to the inventors as of the filing date hereof. Consequently, changes may be made in the arrangement and/or function of any of the elements described in the disclosed exemplary embodiments without departing from the spirit and scope of the invention.
  • A visual indicator display device includes a bracelet, a transparent capillary chamber, and a displacement member. The transparent capillary chamber is matched to an indicia and has a primary length and a width less than the primary length. The displacement member is functionally disposed at one end of the capillary chamber and is responsive to a measureable input for moving a fluid contained therein a defined amount.
  • A suitable fluid may be an oil, a lotion, or a liquid such as a drug or other medication. The displacement member is attached to one end of the capillary chamber which is responsive to a measureable input for displacing the indicator surface thus allowing the user to read a measurement from the indicia.
  • Referring to FIG. 3, an analog indicator 10 of the invention indicates dosage. The indicator 10 includes a reservoir 12, a pump 14, a measuring device 16, a feedback circuit in a controller 20 and a power supply 22′. The reservoir 12 has a longitudinal axis 24 along which a indicia or a scale device 26 is disposed and is adapted for containing a fluid 28 bounded by at least an indicator surface 30. In a preferred embodiment, the pump 14 is made up of the plunger 32 mounted on a screw 33 driven by a micro motor 34. The plunger 32 generally uses an O-ring seal 29 disposed about its circumference, to seal against the fluid 28 passing between the top and bottom surface 31 and 35, respectively, of the plunger. The pump 14 pumps the fluid 28 out of the reservoir 12, and into the catheter 36. In a preferred embodiment, the measuring device 16 is an electronic clock which measures dine and communicates a measured value of time to the feedback circuit 20. The feedback circuit 20, powered by the power supply 22, receives a measured time input from the measuring device 16 corresponding to a position on the scale device 26 and, in response thereto, activates the pump 14 to pump or move the fluid 28 out of the reservoir 12, until the surface 30 reaches a desired position in relation to the corresponding position on the indicia 26 (generally calibrated to equal a desired rate of dispensing of the fluid). The power supply 22 powers the pump 14 and feedback circuit 20. As shown, the reservoir 12 communicates the fluid 28 into the catheter 36. A clasp 52 connects ends of the device 10 to create a bracelet 21.
  • Further, optionally, an optical fiber and an LED light source illuminate the fluid 28 in the reservoir 12 in a known manner.
  • A potentiometer 56 regulates the voltage setting to a displacement control system 60. The displacement control system 60 includes an incremental position sensor 62, for example, the tracker NSE-5310 (the specification of which is attached as Appendix A to U.S. Provisional Application No. 61/235,725, filed 21 Aug. 2009, incorporated herein by reference hereto) located adjacent the plunger 32. This control system 60 includes encoding for direct digital output, in which a hall element array on the chip 62 is used to derive the incremental position of an external magnetic strip 64 placed adjacent the chip at a distance of approximately 0.3 mm (typically), the magnetic strip 64 being attached to the plunger 32 in order to translate therewith. This sensor array detects the ends of the magnetic strip to provide a zero reference point.
  • In an alternate embodiment, the power supply 22 can be solar cells, a wound watch spring, movement captured by an oscillating mass (such as used in automatic watches), or a pneumatic system storing compressed air.
  • To return the fluid 28 to an initial position, such as 6:00 AM, for example, the plunger 32 may be returned by a return spring 40 or a magnetic device (not shown). Other options are conceivable, of course, which include the return line 42, which allows simple reversing of the motor 34 to reset the indicator 10.
  • A suitable motor 34 is referred to by its trademark SQUIGGLE™, available from New Scale Technologies, Inc, of New York, USA.
  • Referring now to FIG& 4A and 4B, an application of the analog indicator of the invention is a wrist watch or necklace 10 worn around the user's wrist. The reservoir 12′ may be made of a transparent or translucent material, or a mixture of transparent and translucent material, formed in any desired shape. It may be made of plastic, rubber, silicon or any suitable material. An elastic material has the advantage that the bracelet 21′ may be stretched over the user's wrist. In addition, the fluidic display 23 may be supplemented with a standard watch face 39 on the casing 43.
  • Referring now to FIG. 5A, the invention may be configured as a device 10″ used to administer doses of liquid drugs 28 such as insulin. In such an embodiment, the flexible tube is a disposable drug reservoir cartridge 12′ attached to housing 13 containing a dosage control device 18. The device 10″ is carried like a wrist watch, with the flexible cartridge 12′ serving as a portion of the hand thereof. The indicator 10″ includes the reservoir 12′, a linear drive 14′, an optional feedback circuit 16′, a controller 20′, and a power supply 22′. The reservoir 12′ has a longitudinal axis 24′ along which indicia 26′ is disposed and is adapted for containing the fluid 2$ bounded by at least an indicator surface 30′. In a preferred embodiment, the linear drive 14′ drives a spherical plunger 32′ mounted on a long flexible threaded shaft 33′ which is driven by a micro motor 34′. The shaft 33′ is preferably made of a superelastic material such as NITINOL. The linear drive 14′ drives the plunger 32′ against the piston 35 (preferably made of a flexible material such as rubber) which in turn presses the fluid 28 along the reservoir 12′ and ultimately through the cannula tube or catheter 36′, which then guides the fluid 28 into the patient's body. The electronics of the device 10″ ensures that a programmed dosage of fluid is administered at regular intervals or constantly as prescribed by a physician. Note that optionally, the fluid 28, instead of passing into a wearer's body via a cannula, charges an absorptive patch 25 worn by the patient, for slow diffusion of the drug into the patient's body through the skin. Where a medication is administered via a patch 25, the patch may include an outer layer which is semi-permeable, in order to prevent the medication from evaporating before it has its intended effect (i.e. diffusion into the skin). Further, a perfume may be delivered in a similar manner. Particularly for the perfume dispensing embodiment, the patch may be located partially or entirely under the housing 13, or to the side of the housing and may be affixed thereto using a temporary adhesive rather than directly to the living organism, in order to avoid the need to attach the same to the living organism. Such a patch may be sized to be replaced in a defined area (such as circular area marked 39) against the back or any side of the housing 13, adjacent the living organism, much like a “POST-IT” note, so that replacement patches can readily replace soiled patches.
  • In a preferred embodiment, the number of turns of the linear drive 14′ is recorded and controlled so as to ensure the proper dosage. The electronics are powered by the power supply 22′. Alternatively, the position of the piston 35 can be controlled in the manner as described in the above embodiment shown in FIG. 3. The cartridge 12′ installs on one side 13′ of the housing 13, with its piston 35 adjacent the plunger 32′, and on the other side 13″, adjacent a piercing mechanism 50 which includes a piercing tube 52 connected to a slidable tab 54. The user may slide the tab 54 to cause the piercing tube 52 to pierce the upper membrane 56 of the cartridge 12′, in order to permit the communication of the fluid 28 through the cannula 38 into the patient's body. Where perfume is dispensed, this piercing served to open one end of the cartridge 12′ to allow the delivery of perfume. into the air, or via a conductive channel (not shown), to, near, or adjacent the skin of the user (for example, directly to and through the patch).
  • In the embodiment using an external magnetic strip (having a magnetic characteristic where the magnetic field generated thereby increases or decreases along the length of the cartridge) attached to or integrated on the cartridge 12′, the computer controller can use this to regulate the dosage administered to the patient.
  • As with the prior embodiment, the power supply 22′ can be a battery, solar power, a wound watch spring, an oscillating mass (such as used in automatic watches), or a pneumatic system storing compressed air.
  • After a cartridge 12′ is fully dispensed, a button (not shown) on the housing 13 can be activated to retract the plunger 32′. The piston 35 remains stationary to prevent any aspiration of fluid from the patient, should the cannula still be connected to the. body. Once retracted, the device 10″ can be reloaded with a replacement cartridge 12′.
  • As with the earlier embodiment, a suitable motor 34 is the SQUIGGLE™ motor already described.
  • Note, that the housing 13 can be fitted with a watch face 39 and corresponding movement (not shown), in order that the drug administration device can also serve as a wrist watch.
  • Optionally, the threaded rod 33′ of the drug administration device 10″ is enclosed in a tube 41 which connects on the side 13″ of the housing 13′ and wraps around the wearer's wrist to reconnect to the side 13′ of the housing, giving the visual effect of a two or multi-banded wrist watch.
  • It is foreseen that the cartridge 12′ used in such drug administration device 10″ would include a chemical litmus-type indicator which would indicate whether the insulin or other drug is suitable for continued injection. This indication could be expressed by an element of the cartridge 12′ changing color, from a color that indicates the fluid is suitable for use, to another color that indicates the fluid is no longer suitable for use.
  • Still further, the device 10″ can be used as a perfume dispenser by replacing the cannula with an aspirating head which can be manually (via a dispenser head or button) or automatically (via the dosage control of the invention) operated.
  • Referring now to FIG. 6, in an alternate embodiment, a cam 152 attached to the stem of a watch movement 132, connects to a fluid displacement device 90 via a piston shaft 160, mounted on sealed hearings 162 to axially translate, which is guided in its axial translation by a cam surface 164 thereof. The piston shaft 160 is connected to a piston head 166 which acts against a flexible roiling diaphragm 170 of a reservoir 36′ (alternatively, of course the piston may have an O-ring mounted about it's periphery or be otherwise sealed, as shown in the embodiment of FIG. 3) The rolling diaphragm 170 has a flange 172 which is sealingly fixed at one end so as to effectively separate a fluid 28 from below the piston head 166, from a fluid 28′ (which may include air as a fluid gas) above the piston. The reservoir 36′ is shown in an extreme position. to A passageway 112′ leads to the capillary channel 120, and a passageway 110′ provides a return passage to the opposite side of the piston head 166.
  • The cam 152 is formed resembling a nautilus spiral so as to progressively move the piston shaft 160 and therefore the piston head 166 to displace a determined amount of fluid 28 into the capillary channel 120, at a rate which will indicate the time accurately. Of course, a similar determined amount of drug or perfume may be administered to living organism in this manner as well
  • Referring now to FIG. 7, again, the alternate fluid displacement device 90 is shown in which the reservoir 36″ is in an essentially filled position. A keyway 180 formed on the piston shaft 160 mates with a set screw 182 which screws into the keyway via threads in the fluid display subassembly 20′, in order to prevent the piston shaft from rotating on its axis, thereby better maintaining the relationship between the extreme end 184 of the piston shaft and the. cam surface 164′. In addition, an adjustment screw 186 having an O-ring seal 190 mounted in a recess therein includes an “ALLEN” or “TORX” interface in an exterior end 192 thereof which allows factory adjustment of the position of the meniscus 30 for calibration purposes. A septum or access port 194 (not shown) or pair thereof, made of an elastic material, may also be used to allow removal and injection of air and fluid 28′ and 29′ into and out of capillary channel 102. and/or reservoir 36″.
  • It should be noted that the invention 10, 10′, 10″ may be made exclusive of all electronics (such as would typically be the case where the invention is positioned in the luxury watch market). In such embodiment, the power source 22″ may be movement from an oscillating mass, which winds a watch spring, which powers a gear train, for which the rate of rotation is controlled by a pendulum-like regulator or oscillating disk (e.g., a balancier/turbion), which has a characteristic period, as known in the art.
