Abstract

A blood glucose meter having a test strip port and an adjustable lancet device disposed at the same end of the device body is disclosed. The device body further includes an enclosure at the proximal end of the device body which houses a test strip storage vial and which facilitates one-handed opening and closing of the vial to simplify access to test strips contained therein. The enclosure is further provided with a window which allows the reading of the lot numbers on the label of the test strip vial therein without necessitating removal of the vial. A data connector is also provided on the device body for communication access, such as to upload data from other devices or to download data to other devices. By combining these multiple components into a single device body, the blood glucose meter requires fewer steps for sampling and testing, and makes device use easier and more convenient.

Description

    CROSS-REFERENCE TO RELATED APPLICATIONS
  • [0001]
    This application claims priority under 35 U.S.C. §119(e) from a U.S. Provisional Patent Application of Gregg Draudt et al., entitled “Blood Glucose Meter Having Integral Lancet And Vial Storage For Single Handed Use And Method For Using Same”, Ser. No. 60/562,536, filed on Apr. 16, 2004, the entire content of which is incorporated herein by reference.
  • FIELD OF THE INVENTION
  • [0002]
    The present invention relates to a blood glucose meter with an integral lancet device, and a location on the device to store test strip vials, such that one-handed use for lancet device, meter and test strip access functions are possible.
  • BACKGROUND OF THE INVENTION
  • [0003]
    As the number of patients suffering from diabetes and similar medical conditions increases, self-monitoring of blood glucose wherein the patient monitors his or her blood glucose levels has become a common practice. Various mechanisms have been created to achieve these results, and typically include a lancet device and a blood glucose meter.
  • [0004]
    Blood glucose meters often further include a memory for storing measured blood glucose values, exercises and meals, along with other related data such as the corresponding dates, time of day, and duration of each, and the units that were used as these values and events were measured. Blood glucose meters are also generally provided with a display screen and user input buttons or controls with which a user can specify which of the stored values to display or functions to access.
  • [0005]
    A blood glucose meter can be configured to receive and read an inserted test strip on which a drop of a patient's blood has been deposited. Still other devices include an integrated lancet device and glucose meter for ease of self-monitoring. Such systems are disclosed, for example, in U.S. Pat. No. 4,787,398, to Garcia et al., entitled “Glucose Medical Monitoring System”, the entire content of which is incorporated herein by reference.
  • [0006]
    In many devices, the lancet mechanism and the detection mechanism are separate. In doing so, the lancet device including the lancet, and the detection unit including the test strip, which are provided separately or are separately mounted on a monitoring system, result in a very complicated operation for the user.
  • [0007]
    Accordingly, a need exists for a device and method to provide a blood glucose meter with an integral lancet device, and a location on the device to store test strip vials, such that one-handed use for lancet device, meter and test strip access functions are possible.
  • SUMMARY OF THE INVENTION
  • [0008]
    It is therefore an object of the present invention to provide a blood glucose meter with an integral lancet device, and a location on the device to store a test strip vial, such that one-handed use for lancet device, meter and test strip access functions are possible.
  • [0009]
    It is another object of the present invention to provide a blood glucose meter with an integral lancet device such that lancing and testing processes are positioned sufficiently close in proximity to allow a virtually continuous short motion by the user to achieve the functions of each.
  • [0010]
    It is another object of the present invention to provide a blood glucose meter with a location on the device to store test strip vials, such that vial access can be achieved using a one-handed motion.
  • [0011]
    It is another object of the present invention to provide a blood glucose meter with a location on the device to store test strip vials, such that vial content information is visible to a user without removal of the vial from the device.
  • [0012]
    It is another object of the present invention to provide a blood glucose meter providing further analytical functions, including communication with other devices.
  • [0013]
    These and other objects are substantially achieved by providing a blood glucose meter having a test strip port and adjustable lancet device disposed at the same end of the device body. The device further includes an enclosure at an opposite end which houses a test strip vial, and which further facilitates one-handed opening and closing of the vial to simplify access to the contained test strips. A data connector or wireless communication module can be located on the bottom of the enclosure of the device for communication access, such as to upload data from other devices and download data to other devices, and a window can be provided on a device surface which allows the reading of lot numbers on the label of the test strip vial without requiring the removal of the vial from the device.

  • DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS
  • [0023]
    The exemplary embodiments of the present invention described below relate to a blood glucose meter with an integral lancet device, and a location on the device to store a test strip vial that holds a number of test strips. The disclosed embodiments of the present invention combine the functionality of each above feature into a streamlined enclosure that optimizes the use of the product for the purpose of monitoring one's blood glucose.
  • [0024]
    FIG. 1 is a perspective view illustrating the top surface of a blood glucose meter in accordance with an embodiment of the present invention. The main features of the disclosed embodiments of the present invention include a device body 10 configured for convenient one-handed use, test strip port 20 and lancet device 30 that are disposed at the same end of the device body 10, thereby allowing a drop of blood extracted by the lancet device 30 to be immediately deposited on the test strip (not shown) in the test strip port 20, a detachable cover 40 which allows lancet replacement and also provides a generous lead-in area 45 to facilitate convenient test strip loading into the test strip port 20, a trigger button 50 on the side of the device body 10 which allows comfortable positioning during lancing, an arming slide 60 on the sides and bottom of the enclosure of the device body 10 which arms the lancing mechanism of the lancet device 30 when moved toward the back of the device, wherein the location of the arming slide 60 keeps the outer size of device body 10 as small as possible, and an enclosure 70 which houses a test strip vial 75 containing multiple test strips and which allows one-handed vial opening. The device body 10 further includes a blood glucose meter 80 for processing the test strip, and a data connector 90 (see FIG. 2) located on the bottom of enclosure for data exchanges with an electronic pen-type injector or other device. The blood glucose meter 80 can further include a display window 82 and a plurality of meter operation buttons or controls 84. The enclosure 70 can further include a window 72 which allows reading of a test strip lot number on a test strip vial 75 label therein without removing the strip vial from the device body 10. By combining these multiple components into a single device body 10, the device requires fewer steps for testing, and makes device use easier, even in confined or less than ideal locations to test one's blood glucose levels.
  • [0025]
    As noted above, many existing devices require the use of a separate blood glucose meter, lancet device and test strip storage vial. These existing devices can, therefore, require an extensive amount of handling and manipulation of separate devices to facilitate the measurement of one's blood glucose, which is an undesirable outcome. The exemplary embodiments of the present invention combine these separate device features into a single device by combining a blood glucose meter, lancet device and test strip storage, thereby requiring much less handling and manipulation to accomplish a desirable outcome.
  • [0026]
    The embodiment of the present invention shown in FIG. 1 takes advantage of the small size of the primary sub-components, including blood glucose sensing circuitry/technology of the blood glucose meter 80, lancet mechanism of the lancet device 30, and test strip storage vial 75, and encapsulates each in an attractive and user-friendly package. The combination of these sub-systems as shown in the embodiment of FIG. 1 results in a reduction in the number of steps required to test one's blood glucose as described in greater detail below. The blood glucose sensing circuitry/technology of the blood glucose meter 80, lancet mechanism of the lancet device 30, and test strip storage vial 75 are well known to those skilled in the art and a detailed description of each is omitted for clarity and conciseness.
  • [0027]

    Many existing devices provide the lancet device at the opposite end from the test strip, requiring the user to perform an awkward maneuver to rotate the unit after lancing. Still other existing devices require either the use of a separate lancet device in the case of meter-only units, or a rotation of the meter in the case of meters with lancet device and test strip port at opposite ends. The embodiments of the present invention solve these problems by placing the test strip port 20 and the lancet of the lancet device 30 in as close proximity as is ergonomically possible at the distal end of the device body 10, thereby minimizing wasted motion.
  • [0038]
    In the disclosed embodiments of the present invention, the geometry of the distal end or tip of the device, which includes the test strip port 20 and the lancet device 30 positioned close together, results from the use of a compact mechanism for the lancet device 30, and a compact integrated printed circuit board for the glucose meter 80 electronics. The device further provides the detachable cover 40 at the distal end, which provides a generous sized lead-in area 45 to guide the test strip into the test strip port 20. As noted above, the lead-in area 45 can further include a color highlighted area (not shown) surrounding the opening of the test strip port 20 for improved visibility and ergonomics.
  • [0039]
    In the use of the embodiments of the present invention as illustrated in FIGS. 3 through 5, a tester can lance any number of positions on a skin surface, such as a bottom surface of a finger or a side surface of a finger. Specifically, FIG. 3 illustrates a lancing technique on a bottom surface of a finger, FIG. 4 illustrates a close-up view of the lancing technique of FIG. 3, and FIG. 5 is a view of a lancing technique on a side surface of a finger. Further, as illustrated in FIGS. 6 and 7, many testers after lancing a skin surface will prefer to use the tip of the device to support the lanced finger and gently roll it over the device tip to apply the blood drop onto the test strip held in the lead-in area 45. Specifically, FIG. 6 illustrates a bottom-lanced finger resting on the device tip, and FIG. 7 illustrates the bottom-lanced finger of FIG. 6 being rolled toward the test strip to apply the blood drop onto the test strip while resting on the device tip. However, as illustrated in FIGS. 8 and 9, many testers after lancing a skin surface may not desire to use the tip of the device to support the lanced finger, but prefer to simply move the lanced skin surface from the device tip to apply the blood drop onto the adjacent test strip held in the lead-in area 45. Specifically, FIG. 8 illustrates a side-lanced finger moved the short distance from the device tip to the test strip, and FIG. 9 illustrates the side-lanced finger of FIG. 8 being used to apply the blood drop onto the test strip.
  • [0040]
    Still other testers may prefer to hold the device stationary and rotate the skin surface across the tip of the lancet device and to the adjacent test strip in a substantially continuous motion. As described below, such a “strip-to-tip rotate” method of use is shown in FIGS. 10 through 12. Still other testers after lancing a skin surface, may prefer to use a second or adjacent finger to support the lanced finger to gently roll it over and toward the test strip to apply the blood drop onto the test strip held in the lead-in area 45.
  • [0041]
    FIGS. 3 through 5 are views illustrating an exemplary manner of use of an embodiment of the present invention for lancing a finger after arming the device. As noted above, the user can first arm the lancet device 30 by firmly grasping the arming slide 60 with one hand and pressing the proximal end of the device body 10 against a surface to move the arming slide 60 within the recess 65.
  • [0042]
    In FIGS. 3 through 5, a test strip 76 is positioned in the lead-in area 45 at the distal end of the device body 10 and adjacent to the lancet device 30 as a user engages the lancet device 30 with a skin surface 95. In doing so, a bottom surface of a finger can be lanced as shown in FIGS. 3 and 4, or a side surface of a finger can be lanced as shown in FIG. 5. The user can then apply the blood drop from the skin surface 95 to the test strip 76 in a number of motions, each requiring a minimal travel distance and device manipulations. Specifically, the user can use the device tip to rest the lanced finger and provide a guide while rolling the blood drop to the adjacent test strip 76, the user can use a second finger to rest the lanced finger and provide a guide while rolling the blood drop to the adjacent test strip 76, the user can rotate the lanced finger about the stationary device to provide the blood drop to the adjacent test strip 76, or the user can simply move the lanced finger a short distance to provide the blood drop to the adjacent test strip 76.
  • [0043]
    In FIGS. 6 and 7, the user is shown applying the blood drop from the skin surface 95 onto the test strip 76 that is positioned in the lead-in area 45. Specifically, the user engages the lancet device 30 with a skin surface 95 (in this case, the bottom surface of the finger) by rolling the skin surface 95 over the tip of the lancet device 30. The tip of the lancet device 30 includes a substantially cylindrical depth control mechanism 32 against which the user engages the skin surface 95. Once lanced, the lancet device 30 is withdrawn slightly from the skin surface 95 to allow the formation of a blood drop on the skin surface 95. The user can then place a different part of the finger (in this case, the side surface of the finger) on the top of the tip of the lancet device 30 as a rest/support surface. In such a rested/supported position, the user can then rotate the lanced finger toward the test strip 76 to apply the blood drop from the skin surface 95 onto the test strip 76 as shown in FIGS. 6 and 7 with less effort, yet with a greater degree of control and precision. The embodiments of the present invention still further allow the user to use a second or adjacent finger as a rest or support when rotating the lanced finger to apply the blood drop onto the test strip 76.
  • [0044]
    Where a rest or support is not required or desired by the user, the user can simply move the finger the short distance between lancet device 30 and the adjacent test strip 76 to apply the blood drop onto the test strip 76 as shown in FIGS. 8 and 9. FIGS. 8 and 9 are views illustrating an exemplary manner of use of an embodiment of the present invention by moving a side-lanced finger a short distance to the test strip to provide the blood drop to the test strip.
  • [0045]
    In the above manners of use, the user can either rotate the finger against the lancet device 30 and toward the test strip 76 in a substantially continuous motion, or move the finger to apply the blood drop onto the test strip 76. For example, the embodiments of the present invention provide for a manner of use in which the finger is rotated against a stationary, or substantially stationary device. FIGS. 10 through 12 are views illustrating an exemplary manner of use of an embodiment of the present invention by rolling the finger over a stationary device and toward a test strip in a substantially continuous motion to provide the blood drop to the test strip. Specifically, in such a “strip-to-tip rotate” method, the user engages the lancet device 30 with a skin surface 95 by rolling the skin surface 95 over the tip of the lancet device 30 to produce a blood drop as shown in FIG. 10. Once lanced, the lancet device 30 is withdrawn slightly from the skin surface 95 to allow the formation of the blood drop. The user can then rotate the finger to bring the blood drop toward the adjacent test strip 76 to apply the blood drop onto the test strip 76 as shown in FIGS. 11 and 12 with less effort, yet with a greater degree of control and precision. In this manner of use, the finger is rotated about the stationary device.
  • [0046]
    Another feature of the embodiments of the present invention described above is the one-handed use of the embodiments to access the test strip vial 75 located in the enclosure 70 at the proximal end of the device body 10. In FIGS. 13 through 16, a user is shown opening and closing the test strip vial 75 with one hand. FIGS. 13 through 16 are views illustrating an exemplary manner of use of an embodiment of the present invention for using a single hand to access a test strip vial.
  • [0047]
    Accordingly, the embodiments of the present invention can include a blood glucose meter 80 with an integral lancet device 30, and an enclosure 70 provided on the device body 10 to store a test strip vial 75 that holds a number of test strips. As noted in FIGS. 1 and 2, the embodiments house the glucose test strip vial 75 in a compartment or enclosure 70 that is located at the proximal end of the device. In doing so, all of the supplies that are typically required for a test are located in the body of the device.
  • [0048]
    Most existing blood glucose meters have a separate test strip vial, and at least one existing device has the test strips mounted on a carousel for dispensing. The embodiments of the present invention described above, however, combine a blood glucose meter 80, lancet device 30, and test strip storage 70, into one device. These embodiments can include any number of variations, however, each combining a lancet device 30 and blood glucose meter 80, with provisions to store a test strip vial 75.
  • [0049]
    The embodiments of the present invention can provide any number of types of inboard, or on-device storage for a strip vial 75 in a meter-lancet device combination, and include any number of types of retention features for the test strip vial 75, such as a friction-type retention feature, a positive mechanical lock, or other similar mechanism for engaging and retaining the test strip vial 75 in the enclosure 70. However, in each embodiment and versions thereof, the test strip vial 75 and enclosure 70 are preferably constructed so that the test strip vial 75 can be operated with one hand as shown in FIGS. 13 through 16.
  • [0050]
    FIGS. 13 through 16 illustrate a one-handed use of an embodiment of the present invention, including a test strip vial 75 and an enclosure 70 with a combined lancet device 30 and blood glucose meter 80. In FIG. 13, a user holds the device body 10 in one hand and positions a finger at the proximal end of the device body 10. Using the finger of one hand, the user can then open the test strip vial 75 located in the enclosure 70 at the proximal end of the device body as shown in FIG. 14 to remove a test strip for use. The user can still further close the test strip vial 75 located at the proximal end of the device body as shown in FIG. 15. The opening and closing operations of the test vial 75 can be further achieved through the use of an extended test vial cap 78 as shown in greater detail in FIG. 16.
