  • Dispensing mechanism 700 includes a cylinder housing 702 with a spring-loaded plunger 703, a T-bar 704, a plunger spring 705, a two-stage lever arm 706, and a return spring 707.
  • Cylinder housing 702 houses spring-loaded plunger 703 and plunger spring 705 centrally above vial cap 304.
  • Reciprocating pusher 220 is operatively aligned with resealable vial 300 and is attached to two-stage lever arm 706 by T-bar 704.
  • an initial lifting actuation of two-stage lever arm 706 causes spring-loaded plunger 703 to be forced into cylinder housing 702, lifting (i.e., disengaging) vial cap 304 away from vial body 302 (since spring-loaded plunger 703 is operatively engaged with a ball joint of vial cap 304 as depicted in FIG. 15C).
  • This disengagement of vial cap 304 from vial body 302 provides a gap G (such as an equidistant gap) and reveals an inner cassette IC within resealable vial 300.
  • Inner cassette IC holds a plurality of test sensors in a stacked array.
  • a subsequent horizontal sliding movement of two-stage lever arm 706 (in the direction of arrow B in FIGs. 15 and 16) drives reciprocating pusher 220, guided by T-bar 704, through gap G, such that a test sensor is engaged and delivered (i.e., dispensed) to the test sensor delivery port of meter 200.
  • reciprocating pusher 220 retracts (due to the action of return spring 707) and vial body 302 and vial cap 304 are closed (i.e., sealed).
  • FIGs. 18-20 depict a dispensing mechanism 800 for opening and closing a resealable vial and dispensing a test sensor contained in the resealable vial.
  • Dispensing mechanism 800 can be employed, for example, with resealable vial 300 of FIG. 9 and with, for example, a meter such as meter 200 of FIGs. 2 and 3. Therefore, and for purposes of illustration only, FIGs. 18-208 depict mechanism 800 along with various components of meter 200 and resealable vial 300.
  • Dispensing mechanism 800 includes a lever arm 802 (with slot 802a), a guide pin 804, a two-stage slider button 806, a lever arm pivot 808, a return block 810, a coil spring 812 (within a plunger 813) and a return spring 814.
  • Slot 802a engages guide pin 804.
  • Reciprocating pusher 220 is coupled to the lever arm 802 and operatively aligned with vial cap 304.
  • Lever arm 802 is in a lowered position when resealable vial 300 is closed, hi the embodiment of FIGs. 18-20, it is assumed that vial body 302 is securely held such that upward movement of vial body 302 is prevented.
  • Two-stage slider button 806 raises lever arm 802 and, thereby, pulls guide pin 804 upwards. This movement serves to simultaneously lift vial cap 304 vertically against the force of coil spring 812 and away from vial body 302 providing gap G and revealing inner cassette IC.
  • a subsequent horizontal movement of two-stage slider button 806 drives reciprocating pusher 220 through gap G such that reciprocating pusher 220 engages a test sensor presented by the inner cassette IC and dispenses the test sensor to a test sensor delivery port (not shown).
  • FIGs. 21 and 22 depict a dispensing mechanism 900 for opening and closing a resealable vial and dispensing a test sensor contained in the resealable vial.
  • Dispensing mechanism 900 can be employed, for example, with resealable vial 500 of FIGs. 11 and 12 and with, for example, a meter such as meter 200 of FIGs. 2 and 3. Therefore, and for purposes of illustration only, FIGs. 2 land 22 depict mechanism 900 along with various components of meter 200 and resalable vial 500.
  • Dispensing mechanism 900 includes a vial block 902 (for holding vial body 502), a slider button 904, a lever arm 906 (with slot 906a), a pivot 908, a return block 910, a lifter 912, a gear wheel pusher 914, a gear block 916, a slider block 918 and a guide pin 920.
  • slider button 904 When resealable vial 500 is in a closed position, slider button 904 remains in a lowered position at one end of lever arm 906 due to, for example, a return spring (not shown) located inside return block 910.
  • Slot 906a engages with guide pin 920 to assist in the opening of resealable vial 500.
  • Slider block 918 remains at the far right end of a slot (not shown) within return block 910. Offset openings 529 in vial cap 504 engage with lifter 912.
  • a flexible sensor pusher (not shown) is provided.
  • the flexible sensor pusher is wound around gear wheel pusher 914 located in gear block 916.
  • slider button 904 is first lifted by the user, and then pushed in the forward direction (i.e., to the left on FIGs. 21 and 22). The lifting of slider button 904 causes lever arm 906 to pivot about pivot 908. Guide pin 920 and slot 906a interact to pull lifter 912 upwards. As vial cap 504 is coupled to lifter 912 by offset openings 529, vial cap 504 is lifted away from vial body 502 against the force of, for example, a spring. Vial cap 504, therefore, becomes disengaged from vial body 502 revealing inner cassette IC and creating gap G.
  • a rack feature engages with a gear wheel (not shown) and rotates gear wheel pusher 914 located in gear block 916.
  • gear wheel pusher 914 rotates, the flexible sensor pusher (not shown) uncoils and is driven through gap G. In doing so, the flexible sensor pusher engages with a test strip presented by inner cassette IC and delivers (i.e., dispenses) the test strip from resealable vial 500.
  • FIGs. 23-25 depict a dispensing mechanism 1000 for opening and closing a resealable vial and dispensing a test sensor contained in the resealable vial.
  • Dispensing mechanism 1000 can be employed, for example, with resealable vial 500 of FIGs. 11 and 12 and with, for example, a meter such as meter 200 of FIGs. 2 and 3. Therefore, and for purposes of illustration only, FIGs. 23 through 25 depict mechanism 1000 along with various components of meter 200 and resalable vial 500.
  • Dispensing mechanism 1000 includes a single-action slider button 1002 (with internal ramps 1004), a vial block 1006 (for holding vial body 502), a guide pin 1008, a gear wheel pusher 1010, a gear block 1012, a lifter 1014, a return block 1016, flexible sensor pusher 1018, a slider block 1020, a return spring 1022, a rack 1024, a gear wheel 1026 and a rod 1028.
  • single-action slider button 1002 is in a rest position on return block 1016 above gear block 1012 and gear wheel pusher 1010 due to the force of a return spring (not shown) located inside return block 1016.
  • a flexible sensor pusher 1018 is wound around gear wheel pusher 1010 located in gear block 1012.
  • Lifter 1014 includes features that slot into offset openings 529 of vial cap 504 to assist with the opening and closing of resealable vial 500.
  • single-action slider button 1002 When single-action slider button 1002 is pushed in the forward direction along return block 1016 (i.e., to the left in FIGs. 23 and 24), vial cap 504 is lifted away from (i.e., disengaged from) vial body 502 by cam action due to internal ramps 1004 on single-action slider button 1002 engaging with guide pins 1008 located on each side of lifter 1014. As single-action slider button 1002 moves forward, guide pins 1008 travel along internal ramps 1004 pulling vial cap 504 away from vial body 502 to create a gap G between vial body 502 and vial cap 504.
  • single-action slider button 1002 engages single- action slider button 1002 with slider block 1020.
  • Slider block 1020 which is attached to a rack 1024, then moves in the forward direction.
  • rack 1024 engages gear wheel 1026 (see Figure 24) causing gear wheel pusher 1010 to rotate.
  • initially single-action slider button 1002 causes opening of resealable vial 500, and it is only when single-action slider button 1002 engages slider block 1020 that flexible sensor pusher 1018 uncoils and is driven through gap G to engage with and dispense a test strip.
  • FIG. 25 depicts the manner in which single-action slider button 1002 is attached to slider block 1020 (that is configured to move along rod 1028 and compresses return spring 1022 located inside return block 1016).
