Abstract

An analysis device is provided comprising a housing having at least two housing parts, a measuring unit and a processor provided therein for purposes of the functionality of the analysis device and generation of analysis data, wherein the device comprises a lock element for producing a generally fixed mechanical connection between the at least two housing parts. Providing such a lock element allows the analysis device to be checked for quality control and/or functionality purposes before the lock element is fitted to the housing, and if the device requires service or repair as a result of such checks then the housing can be reopened without damage to the housing or other aspects of the device. Once the lock element is fitted into a locked position for locking the housing together, subsequent reopening of the housing causes structural effects, including damage or destruction, to either or both of the lock element and the housing or housing parts, ensuring that such reopening becomes apparent to the user.

Claims

1. An analysis device for analyzing a medically significant component of a sample, comprising a housing having an interior and having a measuring unit and a processor each provided in the interior, the measuring unit being configured to perform an analysis on the sample, the processor comprising software configured for processing measured values ascertained by the measuring unit and for preparing data from the measured values, wherein the housing comprises:

at least first, second and third housing parts which integrally define the housing when the housing parts are mated altogether,

the first and second housing parts generally defining the interior of the housing when mated together in a generally mated orientation either with or without the third housing part, the first and second housing parts capable of being unmated without damage when mated together without the third housing part,

the third housing part comprising a lock element configured for locking the first and second housing parts of the housing in the generally mated orientation by producing a generally fixed mechanical connection between the first and second housing parts which connection is irreversible without damage to at least one of the first, second and third housing parts, the lock element comprising a plurality of catch hooks each configured for insertion into corresponding receptacle openings, each opening being either finitely provided in one or both of the first and second housing parts or cooperatively defined by the first and second housing parts being in the generally mated orientation, wherein the housing has an externally integrated structure when the first, second and third housing parts are mated altogether such that the locking function of the lock element is not generally apparent to a user of the analysis device and each of the first, second and third housing parts define at least a portion of the externally integrated structure;

wherein the analysis device is generally functional for its basic purpose when the first and second housing parts are in a generally mated orientation without the third housing part, such that during manufacture of the analysis device at least one functionality check may be performed on the analysis device being assembled except for the lock element of the third housing part and any of flaws and errors that are presented from said at least one functionality check may be corrected or repaired without damage to any housing parts from unmating the first and second housing parts in order to perform the correction or repair.

2. The analysis device according to claim 1, wherein the locking of the housing by the lock element is configured to cause damage to the lock element upon the reopening of the housing.

3. The analysis device according to claim 1, wherein the lock element engages housing parts in such a way that removing the lock element is precluded without causing destruction of the lock element.

4. The analysis device according to claim 1, wherein the lock element comprises a predetermined breaking point configured to break upon at least one of reopening of the housing and removal of the lock element, when the lock element is in the locked position.

5. The analysis device according to claim 1, wherein the lock element comprises a load-bearing component of the housing construction and is configured to contribute to keeping the housing parts mechanically together.

6. The analysis device according to claim 1, the analysis device comprising a device selected from the group consisting of a blood glucose meter, a cholesterol measuring device, and a blood coagulation parameter measuring device, wherein the sample comprises a bodily fluid.

7. The analysis device according to claim 1, wherein the device comprises a portable analysis device which may be manually handled, manually actuated, and manually operated by a user.
