Problems solved by technology

For example, to further reduce the probability of errors due to wear, the allowable lifetime of the device may be reduced
This is bad because it increases the number of "premature" deactivations
The device is deactivated even if the device continues to function without error for an extended period of time

Embodiment Construction

[0094] Figure 1a is a diagram illustrating a first exemplary embodiment of the method according to the invention. When a medical device such as figure 2 The timer is subsequently started according to step 2 when the drug delivery device 10 shown in is used for the first time. First use may refer to the first time the device is turned on, the first time the device is charged, the first time a cartridge is inserted, and the like. In general, every detectable step taken while the medical device is being used can be used as a trigger for a timer.

[0095] After the timer has started, the user starts and continues using the device as planned, as shown in step 3. During this "use" of the medical device, one or more transmission systems 500 of the medical device (such as Figure 9 shown) operation. These operations can be, for example, the number of steps of a stepper motor or a motor rewind operation. When the relevant operation of the transmission system as part of the secon...

Abstract

The current invention relates to a method for detecting a limit of use of a medical device comprising the steps of starting a timer of a medical device when said medical device is used for the first time, detecting the limit of use of the medical device and indicating the limit of use of the medical device. The technical problem of providing a method and a medical device, the safety of which is further increased and at the same time the limit of use is not prematurely induced is solved by a generic method wherein the limit of use is reached when at least one of a first criterion and a second criterion is met, wherein the first criterion is that the timer reaches or exceeds a time limit and wherein the second criterion is that at least one operation of a drive train of said medical device reaches or exceeds a limit. The technical problem is further solved by a medical device for performing a method according to the invention.

Description

technical field [0001] The invention relates to a method for detecting the use limit of a medical device, comprising the steps of: starting a timer of the medical device when the medical device is used for the first time; detecting the use limit of the medical device; and indicating the use limit of the medical device. The invention also relates to a medical device for carrying out the method according to the invention. [0002] For some devices, the lifetime of the device must be limited, although the devices may still be functional. This is especially true, for example, when the correct functioning of the device is mandatory for the physical integrity of the user of the device. This is especially true for medical devices, since the dosage of a certain drug administered by the device or the correctness of the data given or evaluated by the device is in many cases mandatory for the health of the patient. Thus, devices that cannot be permanently checked or checked can be disa...
