Abstract

The invention relates to an apparatus (5) for handling measurement strips (1) needed for taking liquid samples, such as blood samples, the measurement strips having porous material for absorbing and analyzing a liquid sample. The apparatus (5), according to the invention, is formed of a store (6) of measurement strips that receive samples, the store having a compound construction, a store (7) of used measurement strips and a measurement strip feeding mechanism (8,9). The apparatus has preferably been integrated into a casing, which can be connected as part of a mobile phone or a corresponding device.

Claims

1. A portable apparatus for handling measurement strips needed for taking liquid samples, the measurement strips having liquid absorbing material for absorbing a liquid sample, the apparatus comprising first and second elongate storage boxes having first and second ends, respectively, in side by side immediately adjoining relationship, the first storage box adapted to store unused measurement strips in a first upright stack, the second storage box adapted to store used measurement strips in a second upright stack to temporarily retain them for subsequent sanitary disposal and a measurement strip feeding mechanism for transporting measurement strips from the second end of the first storage box to the second end of the second storage box, one by one, via a position at which the measurement strips receive the liquid samples, the second ends, respectively, of the first and second storage boxes being in immediately adjoining relationship.

2. An apparatus, according to claim 1, wherein the measurement strips are essentially formed of frames, in the shape of a square or a rectangle, inside of which an absorbent material for absorbing and analysing a liquid sample has been placed.

3. An apparatus, according to claim 1, wherein the feeding mechanism of the measurement strips is formed of a slide closing one end of the adjacent storage boxes and moving in relation to them, in a recess of which the box, containing the unused measurement strips, has been arranged to surrender one measurement strip, when the slide is in its extreme position, and that the measurement strip has been arranged to receive a sample, when the slide is in its other extreme position, and that the measurement strip, containing the sample, has been arranged for being analysed and fed from said recess into the box, containing used measurement strips, when the slide is in a position between said two extreme positions.

4. An apparatus, according to claim 1, wherein the apparatus has been integrated into a casing, which can be connected as part of a mobile phone or a corresponding device.

5. An apparatus, according to claim 1, wherein, in addition, it comprises, in the same casing, a sample analysing apparatus, as well as a lancet for lancing the skin for taking a blood sample.

6. A portable apparatus according to claim 1 wherein the fist store has an open first end and a second end distant therefrom;

wherein the second store has an open first end adjacent the first end of the first store and a second end distant therefrom adjacent the second end of the first store; and

wherein the measurement strip feeding mechanism is operable for transporting measurement strips from the second end of the first store to the second end of the second store.

7. A portable apparatus according to claim 1 wherein the portable apparatus includes an analyzing unit for analyzing a chemical imparted to the measurement strip.

8. A portable apparatus according to claim 7 wherein the chemical imparted to the measurement strip is in a body fluid and wherein the measurement strip feeding mechanism is operable for transporting the measurement strip from a body fluid receiving position to an analysis position to the second store.

9. A portable apparatus according to claim 7 wherein blood is imparted to the measurement strip and wherein the measurement strip feeding mechanism is operable for transporting the measurement strip from a blood receiving position to an analysis position to the second store.

10. A portable storage device for storing measurement strips needed for taking liquid samples, the measurement strips having liquid absorbing material for absorbing a liquid sample, the device comprising a first store for storing unused measurement strips in a first pile, a second store for storing used measurement strips in a second pile the first and second stores being in immediate adjacent relationship and a measurement strip feeding mechanism for transporting the measurements strips, the measurement strips being transportable from the first store to the second store via a position at which the measurement strips receive the liquid sample.

11. A portable apparatus for handling measurement strips needed for taking liquid samples, the measurement strips having liquid absorbing material for absorbing a liquid sample, the apparatus comprising a first storage box for storing unused measurement strips in a first upright stack, a second storage box for storing used measurement strips to a second upright stack, the first and second storage boxes being in side by side immediately adjoining relationship, the storage boxes having first and second ends, respectively, the second ends being in immediately adjoining relationship, a measurement strip feeding mechanism for transporting measurement strips from the second end of the first storage box to the second end of the second storage box via a position at which the measurement strips receive the liquid samples and an analyzing unit for analyzing the liquid samples to produce analysis results, the portable apparatus being used in combination with a mobile phone, the mobile phone being used to transmit the analysis results through a mobile telephone network.
