The present invention generally relates to an integrated-diagnostic instrument and, more particularly, to a flip-top integrated-diagnostic instrument that is used for storing analyte-testing instruments and in determining an analyte concentration (e.g., glucose) in a fluid (e.g., blood).
The quantitative determination of analytes in body fluids is of great importance in the diagnoses and maintenance of certain physiological abnormalities. For example, lactate, cholesterol, and bilirubin should be monitored in certain individuals. In particular, determining glucose in body fluids is important to diabetic individuals who must frequently check the glucose level in their body fluids to regulate the glucose intake in their diets. The results of such tests can be used to determine what, if any, insulin or other medication needs to be administered. In one type of testing system, test sensors are used to test a fluid such as a sample of blood.
Many individuals perform testing of their blood glucose at several different locations. These locations often include their home or place of employment, such as an office building or work site. Many of these individuals who must test for glucose or other analytes carry with them a meter, a container of test sensors, a lancet, disposable lancets, and/or other analyte-testing instruments. The analyte-testing instruments may shift and potentially become damaged while being transported or carried. Transporting the analyte-testing instruments may also have other disadvantages, such as bulkiness and/or inconvenience.
It would be desirable to have an integrated-diagnostic instrument that assists in addressing one or more of the above disadvantages.

Referring to
The integrated-diagnostic instrument 10 comprises a housing 12, a display 16, and at least one compartment 18a,b. The housing 12 includes a first portion 30 and a second portion 26. The first portion 30 forms at least one test-sensor opening 20 therein. The opening 20 is adapted to receive and/or hold a test sensor and assist in determining the analyte concentration of a fluid sample. The housing 12 of the cartridge is typically made of a polymeric material. Non-limiting examples of polymeric materials include polycarbonate, ABS, nylon, polypropylene, and/or combinations thereof. The instrument 10 is desirably sized so that it may fit generally within a user's purse or pocket.
To communicate at least the analyte concentration to the user, the instrument 10 includes a display 16. One example of a display 16 that may be used in the instrument 10 is a liquid-crystal display. The liquid-crystal display typically shows information from the testing procedure and/or in response to signals input by a user-interface mechanism (e.g., buttons 22a, 22b) on the instrument 10. For example, the user-interface mechanism may be depressed to recall and view results of prior testing procedures on the display 16. It is contemplated that other user-interface mechanisms may be used, including, but not limited to, scroll wheels or the like.
According to the present invention, the instrument 10 has a “flip-top” feature, wherein an end of the second portion 26 is hingedly connected to an end of the first portion 30 via a hinged mechanism. The hinged mechanism allows for the second portion 26 to be moved between an open position (see

The instrument 10 desirably includes a plurality of compartments 18a, 18b, as shown in
An additional benefit of the flip-top feature of the instrument 10 is that the display 16 is generally protected from damage and scratching when the instrument 10 is in the closed position of
It is desirable that the instrument 10 have a footprint area of less than 12 in2 to enhance portability. The instrument 10 may even have a footprint area of about 6 in2. The footprint area is the length L of the instrument times the width W of the instrument (see
The instrument 10 also serves as a convenient device for carrying and protecting the glucose or other analyte-testing instruments. When in the closed position of
Because the display 16 is positioned on the second portion 26, while the at least one compartment 18 and the user-interface buttons 22a,b are positioned on the first portion 30, the display 16 may generally span the length L and width W of the instrument 10. Thus, the display 16 may be relatively large, assisting in the readability of the information displayed on the display 16, especially for those individuals with poor vision. Moreover, a larger display 16 may also be used to display additional information including, but not limited to, graphical interpretations of historical glucose readings. For example, the display 16 typically has an area of at least about 3.75 in2, such as 2.5 inch×1.5 inch. The display 16 may even have an area of at least about 8.75 in2, such as 3.5 inch×2.5 inch. Some of the information that may be shown on the display may include, but is not limited to, the following: a numerical display, an indication of the number of sensors remaining, an indication to load a cartridge or test sensor into the instrument, an apply-blood indication, a temperature indication, results of prior testing procedures, meal and/or exercise indicators, and/or various combinations thereof. The instrument 10 may also include a navigation button 42, a scroll wheel, or any mechanism suitable for scrolling through the information displayed on the display 16.
At least one of the buttons 22a, 22b, 42 may be depressed to operate the electronics of the instrument 10. The instrument 10 typically includes a microprocessor or the like for processing and/or storing data generated during the testing procedure. It is contemplated that the number of buttons on the instrument may be different than depicted in
According to another embodiment, the display 16 may communicate in an audible manner instead of or in addition to the above-discussed visual manner. Thus, the display 16 may be designed to operate in audible and visual manners.
The instrument 10 includes at least one compartment 18a,b that is adapted to contain a lancing device. Turning to
An endcap 180 may be removably attached to the endcap support 160. When attached, the endcap 180 is retained on the endcap support 160 by a pair of support arms 190a-b integrally formed with the endcap support 160.
To use the lancing device 100, the movable housing 114 is pulled away from the main housing 120 to move an internal lancet mechanism 129 to a cocked position, and then a pushbutton 122 is pushed to actuate the lancet mechanism 129 so that a sharp tip 131 of a lancet is forced through an aperture in the endcap 180. The lancing device 100 may be provided with a number of different endcaps 180, each having a different opening, diameter, and/or shape, to facilitate the formation of skin punctures of various depths. Alternatively, the endcap 180 may include an adjustable dial 124 for allowing punctures of different depths to be performed utilizing a single endcap 180. It is contemplated that other types of lancet devices may be also used with the instrument 10.
According to another embodiment, a lancing device is attached to and/or incorporated within the first portion, as shown in
According to one embodiment, the lancing device 214 is manually operated. If the lancet device 214 is manually operated, the lancet device 214 according to one process is cocked by the user and then activated by pressing a button. For example, a button 240 may be used to activate a lancet 234 in a manually operated lancet device 214. It is further contemplated that the lancet 234 may be activated by techniques other than pressing the button 240. For example, the lancet 234 may be activated by a lever mechanism. It is farther contemplated that the manually operated lancet device 214 may further include a mains-powered vacuum to assist in enhancing the fluid flow.
Alternatively, the lancing device 214 of
Referring back to
A test sensor may be removed from, for example, one of the compartments 18a,b and then manually placed in the test-sensor opening 20. According to another process, a test sensor may be automatically advanced to the opening 20 by utilizing the user-interface (e.g., a user pressing one of the buttons 22a,b). The instrument 10 is generally turned on after the test sensor is placed into or advanced into the test-sensor opening 20. After the instrument 10 is powered on, the testing is ready to begin.
The user typically places his/her finger up to a lancing device to generate a whole blood sample. It is contemplated that a blood sample may be generated from other areas of the body. The user then removes his/her finger from the lancing device and brings the whole blood sample into contact with the sensor, wherein the blood is generally drawn into the sensor by capillary action. The test sensors are typically provided with a capillary channel that extends from the front or testing end of the sensors to biosensing or reagent material disposed in the sensor. The biosensing or reagent material is designed to react with the desired analyte to be tested. When the testing end of the sensor is placed into fluid (e.g., blood that is accumulated on a person's finger after the finger has been pricked), a portion of the fluid is drawn into the capillary channel by capillary action. The fluid then chemically reacts with the reagent material in the sensor so that an electrical signal indicative of the blood glucose level being tested is supplied and subsequently transmitted to an electrical assembly. After a minimum amount of blood is drawn into the test sensor, the testing is performed, and the result is, for example, shown on the display 16 and stored in memory. The result of the testing may also be announced audibly, by, for example, using a speaker, and stored in memory.
After the testing has been completed, the test sensor may be removed from the test-sensor opening 20 by several methods. In one embodiment, the instrument 10 may include an eject mechanism 40 that ejects the used test sensor from the instrument 10. Such an eject mechanism 40 may automatically move the used test sensor into one of the compartments 18a,b. In such an embodiment, the test sensors are released forcefully. In a further embodiment, the test sensor may be removed manually from the instrument 10.
According to another embodiment, a disposable cartridge that contains a plurality of test sensors may be used. One example of a disposable cartridge that may be used in the instrument 10 is depicted in
The instrument 10 according to a further embodiment may include a programmable alarm 44 to alert the user to begin testing. The alarm 44 is programmed to sound at a predetermined schedule. An alarm is especially useful for those individuals who have poor memory as well as those individuals who become easily preoccupied and/or forget to test according to a predetermined schedule.
The instrument 10 may include a built-in data management system 46 that is accessible to remote monitoring by, for example, a physician. Such a built-in data management system 46 may be connected for remote monitoring by, for example, a telephone line 48 and a modem 50.
The instrument 10 may also include a bar code reader that reads a bar code label on a disposable test-sensor cartridge. The bar code reader may determine information such as the lot number and calibration numbers for a particular test sensor being used.
