Handheld analysis device
A handheld medical device for body fluid analysis such as to measure an analyte concentration, for example glucose, in a body fluid such as blood or interstitial fluid by a patient or caregiver. The device comprises a mechanical assembly having a transport unit for consumable analytical elements, a display unit, a sensor for analyzing a body fluid sample obtained by a lancet prick, a memory for storing a series of measurement results, a first actuating element, the actuation of which transfers the device into a first active state, activates the mechanical assembly and prepares a measurement. In the first active state, a measurement is started by the actuation of one of the actuating elements, and a second actuating element, the actuation of which transfers the device into a second active state. The display unit is switched on by the actuation of the second actuating element, without activating the mechanical assembly.
1 . A handheld analysis device, comprising:
a mechanical assembly, which comprises a transport unit for consumable analytical elements;
a display unit;
a sensor for analyzing a body fluid sample obtained by a lancet prick;
a memory for storing a series of measurement results;
a first actuating element, the actuation of which transfers the device into a first active state, activates the mechanical assembly and prepares a measurement, with the measurement being started in the first active state by actuating one of the actuating elements; and,
a second actuating element, the actuation of which transfers the device into a second active state;
wherein the display unit is switched on by the actuation of the second actuating element, without activating the mechanical assembly.
2 . The handheld analysis device as in claim 1 wherein the first actuating element is a cover for a device opening on which the body fluid sample is taken up.
3 . The handheld analysis device as in claim 2 wherein the cover can be pivoted.
4 . The handheld analysis device as in claim 2 wherein a third actuating element is provided for triggering a measurement, the third actuating element being disposed on a device opening and configured to be actuated by placing a body part on which a puncture wound is to be generated against the device opening.
5 . The handheld analysis device as in claim 4 wherein a starting position, the first actuating element covers the third actuating element, and the first actuating element covers the device opening.
6 . The handheld analysis device as in claim 1 wherein the mechanical assembly comprises a lancing drive so as to cause the lancets to perform a piercing movement.
7 . The handheld analysis device as in claim 6 wherein a measurement is prepared by charging a mechanical energy storage means of the lancing drive.
8 . The handheld analysis device as in claim 7 wherein a measurement is prepared by coupling the lancing drive to a lancet.
9 . The handheld analysis device as in claim 1 wherein the consumable elements are test elements and/or lancets.
10 . The handheld analysis device as in claim 1 wherein the mechanical assembly comprises an electric motor.
11 . The handheld analysis device as in claim 1 wherein a measurement is prepared in that an consumable element is removed by the transport unit from an consumable element supply.
12 . The handheld analysis device as in claim 1 wherein the display unit is switched on by actuating the first actuating element.
13 . The handheld analysis device as in claim 1 wherein device settings can be modified in the second active state.
14 . The handheld analysis device as in claim 1 wherein measurement results can be displayed by the display unit in the second active state.
15 . The handheld analysis device as in claim 1 wherein it transitions from the second active state into an inactive state, in which the display unit is switched off.
16 . The handheld analysis device as in claim 15 wherein it automatically transitions from the second active state into the inactive state when no actuating element was actuated during a predefined time period.
17 . The handheld analysis device as in claim 1 wherein the mechanical assembly can be deactivated by actuating the first actuating element.
18 . The handheld analysis device as in claim 1 further comprising, a magazine that can be inserted in the device, the magazine containing a consumable element supply.
19 . A handheld analysis device, comprising:
a mechanical assembly, which comprises a transport unit for consumable analytical elements;
a display unit;
a sensor for analyzing a body fluid sample obtained by a lancet prick;
a memory for storing a series of measurement results;
a means for first actuating to transfer the device into a first active state, activates the mechanical assembly and prepares a measurement, with a measurement being started in the first active state by actuating one of the actuating elements; and,
a means for second actuating to transfer the device into a second active state that switches on the display unit without activating the mechanical assembly.
