    CASSETTE AND ANALYZING DEVICE
    DESCRIPTION RELATED APPLICATIONS
    This application claims priority of Australian Patent Application number 2012904135, Australian Patent Application number 2012904710 and Australian Patent Application No. 2013901667, the content of which is incorporated herein by reference.
    SCOPE OF THE INVENTION
    The present invention relates to a cassette for housing a carrier of analysis elements and aspects of loading the cassette in an analyzer device.
    BACKGROUND OF THE INVENTION
    Samples of body fluids such as blood, plasma, urine, interstitial fluid, etc., can be analyzed for various components or properties, such as glucose, cholesterol, pathogens, drugs of abuse, coagulation. , hematocrit, etc. The body fluid sample is applied to an analysis element that contains reactive ingredients. A reaction occurs and a result occurs. An instrument may be necessary in order to read the result or the result may be interpreted by sight, for example, the comparison of color or symbols such as bars, dots, etc.
    The analysis elements can be supplied in multiple quantities along a carrier tape housed in a cassette. The analysis cassette is provided with two cameras, a sealed supply chamber containing the tape with unused analysis elements and a collection chamber for the storage of the tape with the analysis elements used. The analysis cassette can be used in a laboratory analyzer or in a portable analyzer.
    Due to a number of reasons, it can be problematic to load the cassette into the analyzer. In general, a sensor head of the analyzer is necessary to come into contact with the tape and the analysis element. In the case of biosensors, the detector head must have an electrical connection and, in the case of a photometric analysis, the analysis element needs to be located at a fixed distance from the analyzer's optics. In this way, the tape needs to be reliably placed at a specific site for analysis, relative to the sensor head.
    US Patent No. US7378270 (Roobik, et al.) Discloses a cassette that is inserted into an analyzer, whereby a sensor head of the analyzer moves forward in contact with the tape. The movable head complicates the construction and is not ideal for low-cost portable analyzers.
    Olra solution consists of placing the tape on a sensor head manually. This requires that the cassette be manipulated in a position to place the tape on the sensor head before inserting the cassette into the analyzer. This approach may be suitable for a trained technician, but it is not suitable for an inexperienced user.
    Even when the tape is loaded correctly in an analyzer, there may be a problem with a new analysis element that is dragged out of the supply chamber by accidentally activating a driving wheel.
    If a new analysis element is inadvertently removed from the supply chamber early, the analysis element will be prematurely exposed to environmental conditions, which may adversely affect the reagents in the analysis element. For example, the analysis elements can be exposed to moisture, which can adversely affect the performance of the analysis.
    If an analysis element is only partially removed from the supply chamber, the sealing of the supply chamber may be compromised. This may allow moisture to enter the supply chamber. Because the analysis elements are generally hydrophilic, this can damage all analyzes in the chamber.
    Therefore, it is desirable to avoid accidental activation of the driving wheel unless an analysis is arranged to be carried out.
    OBJECTIVE OF THE INVENTION
    The present invention aims to address or improve at least one of the problems mentioned above.

    Detailed description of the invention
    Referring first to Figure 1, part of a cassette 1 is shown in the form of a wrapper 2 that includes a body 3 with a supply reel 4 and a pick-up reel 5. A tape 6 extends from the reel of supply 4, through an area for analysis 7 and to pickup reel 5.
    The supply reel 4 is located in a supply chamber 6 which is defined by a front wall 9, a rear wall 10 and a side wall 11. An additional side wall 12 serves to close the chamber 6. The wall 12 is secured to the rear wall 10 and projects after an end 13 of the front wall 9 in order to define a small gap 14 between the wall 12 and the front wall 9, so that the tape 6 leaves the chamber 6.
    An elongated finger 15 projects from the front wall 9 and the wall 12 is arranged in order to settle in the vicinity of the finger 15 to hold a seal 16 against the tape 6, just as the tape 6 is extracted through a channel 17 between wall 12 and finger 15. Finger 15 ends in a guide 18 which has an angle towards the area for analysis 7, in order to direct the tape 6 to the area for analysis 7, where it is located an analysis element 19 for the analysis.
    A corresponding guide 20 is placed on the opposite side of the area for analysis 7 in order to direct the used belt 6 down the side wall 11, on a brake 21 (which keeps the tape in tension through the area for analysis 7) and on pickup reel 5.
    Referring to Fig. 2, the cassette casing 2 is shown mounted in a housing 22 to form the complete cassette 1. The housing 22 is adjusted in the casing 2 using clips 23 such that a base 24 of the housing 22 is It closes at least partially on the pick-up reel 5 and a circular opening 25 is provided to allow access to the reel 5.
    The base 24 includes lateral extensions 26 that overlap the guides 18, 20. A part of the bridge 27 extends between the guides 18, 20 in order to form a frame 30 that is aligned with the tape 6, shown on the dotted lines. A "bias" element 31 is projected from base 24 in a free space 32 adjacent to zone 7 for analysis.
    Referring now to Figure 3, the tape 6 is illustrated being tensioned between the guides 18, 20, parallel to and laterally adjacent to the frame 30 such that the bridge part 27 is in a protective position in relation to the tape 6. Thus, the frame 30 protects the belt 6 laterally, on a loading side 28, from damage or twisting. Table 30 is shown forming a window 33 in front of tape 6, so that blood or other material for analysis can be deposited on tape 6.
    Referring now to Figure 4, an analyzer device 40 is illustrated which includes a main body 41 with a recessed housing 42 with an inner curved end 43 and an open outer end 44. The structure 45 projects upwardly from a floor 46 of the housing 42, adjacent to the outer end 44 of the housing 42. The structure 45 includes a post 47 with a sensor head 48 defining a site for analysis 49 at a front part 50 and a recess 51 at a lower end 52 of position 47 An inclined surface 53 is provided in the form of a wedge profile 54 in a rear portion 55 of the structure 45.
    A winch 56 projects upward from the floor 46, towards the inner end 43 of the housing
    42. The winch 56 is designed to fit in the pick-up reel 5 and the structure 45 is designed to be received in the area for analysis 7 of the cassette 1, when the cassette 1 is loaded into the housing 42 of the device 40, as shown in Figure 5, where the frame 30 is shown chopped above the head of the sensor 48 and in the recess 51, to lock the cassette 1 in place.
    Referring to Figure 6, the winch 56 is shown connected to a gear mechanism 57 in order to rotate about a fixed shaft 58. The gear mechanism 57 includes a driving wheel 59 and an input gear 60. It is provided a locking mechanism 61 that includes a lever 62 for engaging in the teeth 63 of the driving wheel 59 and thus preventing the rotation of the driving wheel 59.
    Figure 6 also clearly shows the inclined surface 53, behind the sensor head 48, such as the wedge and conic shape is backward, towards the floor 46 of the housing 42. At the end
    Lower 52 of post 47 defines the recess 51 below a forward nose portion 64 of post 47.
    Referring to Figures 7 and 8, the device 40 also includes a sliding cover 70, which is shown in the open position, where the sensing head 48 is exposed for analysis purposes. In that arrangement, the locking mechanism 61 (as shown in Figure 6) is deactivated in order to allow the winch 56 to be rotated under the action of a selector wheel 71.
    The housing 42 also includes two latches 72 at the inner end 43 of the housing 42, adjacent to the floor 46. The latches 72 have an inclined upper cover 73 and a counter-output flange 74. The inclined surface 53 is provided from an upper surface 75 of the placed 47 and continues to lower in separate wedge profiles 54 that are substantially in inertia with the latches 72 at the inner end 43 of the housing 42.
    Turning now to Figure 9, a lower rear edge 76 of the cassette 1 is provided with two retainers 77 which are each formed with a beveled edge 78 and an upper cornice 79. During the movement of the cassette 1 in the device 40 of Figure 7, in the direction of insertion indicated by the arrow "D", the beveled edge 78 of each retainer 77 is designed to interact with the inclined upper cover 73 of the latches 72. This has the effect of forcing the cassette 1 in an initial forward direction "F" in order to ensure that the frame 30 clears the structure 45 at the outer end 44 of the housing 42, while protecting the tape 6 from the side hitch or damage from the structure 45.
    After the beveled edges 78 clear the respective upper platforms 73, the upper commanders 79 slide under the rear projections 74, in a backward direction "R", in order to block a rear end 80 of the cassette 1 in the device 40.
    Referring to figure 10, the element "bias" 31 is positioned to meet the wedge profile 54
    at the rear 55 of structure 45 (as shown in Figure 8). when the frame 30 extends over the head of the sensor 48. According to the cassette 1 it is moved in the "O" insertion direction, the frame 30 is forced downwards on the structure 45 that activates the element "bias" 31 and causes the frame engages resiliently with position 47, until the bridge part 27 is inserted in the recess 51 in position 47, which allows the cassette 1 to move backwards "R" in such a way as to block the seals 77 under the latches 72. This action causes the tape 6 to be tensioned at the site for analysis 49, on the head of the sensor 48. As can be seen, during the movement of the cassette 1 in the insertion direction " Or ", the tape 6 is protected from the side hitch with the sensor head 48 by the frame 30, which prevents damage to the tape 6.
    The entire process of loading the cassette 1 into the device 40 is illustrated in the schematic drawings of Figure 18.
    In particular, Figure 18a shows cassette 1 being displaced in the "O" insertion direction. Figure 18 b illustrates the frame 30 being forced in the forward direction "F", as the movement of the belt continues in the "O" direction. The forward movement of the frame 30 is effected by a combination of the resilient hitch with the structure 45 and the cassette 1 activating the latches 72.
    In Figure 18 c, winch 56 has been received in pickup reel 5 and the action of the element "bias" 31 in structure 45 urges cassette 1 in the backward direction "R", such that the frame 30 fits into slot 51. Figure 16 d shows cassette 1 in the fully loaded condition.
    Referring now to Figure 11, the relative position of the pick-up reel 5 inside the cassette during the loading operation is described in more detail. The pick-up reel 5 appears displaced laterally towards the rear end 60 of the cassette 1. This is the position that the reel 5 needs to adopt to engage the winch 56 during the initial insertion of the cassette 1 into the housing 42 of the device 40. Since The winch 56 is arranged to rotate on a fixed axis 58, the pick-up reel 5 needs to be able to float relative to the winch 56, as the housing 22 of the cassette moves relative to the winch 56 during insertion. In particular, cassette 1 initially slides in the forward direction "F" and then back in the backward direction "R" during insertion into the device 40.
    With respect to Figure 12, the pick-up reel 5 can simply float by being housed in a pick-up chamber 82, which is defined between the base 24 and a cover 63 of the cassette 1. In this way, the pick-up reel 5 is free to float by sliding along pickup chamber 82 and cassette 1, as necessary. The supply reel 4, on the other hand, is mounted on a core 84 that is sealed inside the supply chamber 6, in order to rotate on a fixed axis 65.
    Since the pick-up reel 5 is free to move along the housing 22, the reel 5 does not have a reliable mechanism for maintaining the tension of the tape 6 when the cassette 1 is outside the analyzer device 40. In this way, it it uses a separate and independent mechanism to maintain the tension of the belt 6, in the form of the brake 21, described with reference to Figure 1. The brake 21 is preferably an integrally molded part of the housing 22, located between the area for analysis. 7 and the pick-up reel 5. The brake 21 is formed by thermoplastic elastic material, in order to grip the belt against the housing 22 and maintain the tension of the belt 6 throughout the area for analysis 7, thus allowing the reel moves freely when it is outside the analyzer 40.
    Referring to Figure 13, the device 40 has a start-up button 86, an analysis function button 67 and a screen 66 to show an analysis result. The device 40 is shown with the sliding cover 70 in the closed position, which locks the selector wheel 71 against rotation or at least prevents the belt 6 from being rolled forward by the selector wheel 71, even if the wheel be turned.
    Referring to Figure 14, the selector wheel 71 connected to the input gear 60 is shown, which meshes with the teeth 63 of the driving wheel 59. The lever 62 is mounted on a core 69 and a resilient member 90 keeps the lever engaged. with the driving wheel 59. Thus the selector wheel 71 is prevented to rotate the driving wheel 59. A clutch device 91 can be provided to allow free rotation of the selector wheel 71 until the lever 62 is released.
    Referring now to Figure 15, the sliding cover 70 is attached to a tail 92 that is forced to slide along an elongated track 93 on one side 94 of the device 40. The tail 92 has a tongue 95 arranged to activate the lever 62 when sliding cover 70 is opened.
    With reference to Figure 16, the sliding cover 70 is shown in the open position, where the tongue 95 has the lever 62 engaged and the lever 62 rotated against the resistance of the resilient member 90, to allow rotation of the driving wheel 59 In that position, the selector wheel 71 can be rotated to advance the belt 6 through the sensor head 46 in order to present a new analysis element 19 for the site for analysis 49.
    With respect to Figure 17, the sliding cover 70 reappears in an open position in which the tape 6 is shown tensioned between the guides 16, 20 such that the analysis element 19 is located on the sensor head 46 This allows a sample of blood or other material to be deposited in the analysis element 19 for analysis purposes. When the analysis has been completed, the belt 6 can be advanced by rotating the selector wheel 71, which engages the driving wheel 59 in order to wind the analysis element 19 used in the collection chamber 62 and order an element of analysis 19 new out of supply chamber 6 and on site for analysis 49.
    If the analysis is complete, the cover 70 can be slid back into the closed position, to activate the locking mechanism 61 in order to secure the driving wheel 59 against further rotation. In this way, the tape 6 is prevented from being inadvertently dragged out of the supply chamber 6.
    From the foregoing it should be appreciated that the cassette 1 allows the tape 6 to be reliably fixed on a site for analysis 49, without damage from the lateral load on the head of the sensor 48. Since the cassette 1 is displaced longitudinally and backward during insertion, the tape 6 is tensioned at the site for analysis 49 in such a way as to provide proximity and
    contact between the tape 6 and the sensor head 48, if necessary. To remove the cassette 1, the housing 22 is simply pressed forward, with the resistance of the polarization element 31, causing the cassette 1 to rise upward on the inclined surface 53 of the structure 45 and away from the floor 46 of the housing 42. In this way, the cassette 1 can be easily and reliably exchanged inside and outside the apparatus 40. By using the cassette 1, the tape 6 is automatically loaded into the head of the sensor 48, without requiring a specialized technician to load the tape separately at the site for analysis 49.
