Embodiment Construction

[0076] figure 1 A schematic diagram illustrating an embodiment of the method according to the invention is shown figure 1 . A first step 2 is to receive information about a desired dose, which may be provided, for example, by a user, another computing unit or a memory unit. Users can use the Figure 4 and 6 The interface in the form of dose setting buttons 62 , 64 , 66 is shown. In order to provide a more accurate dose, in step 4 account is taken of the fluid elements 18 connected to the first reservoir 14 and the second reservoir 16 (cf. Figure 2a ) Relevant information on the contents of 6. This information 6 may include, for example, information on doses previously expelled from the first and / or second reservoir 6a, time information 6b on the last activation performed or elapsed time since the last device use or expelling, information on past or Information 6c on the current temperature and / or information 6d on the degree of movement of the medical device 12 . These...

Abstract

The invention relates to a method for delivering at least one fluid medicament from a medical device. The invention also relates to a medical device. The technical problem of improving the dose accuracy is solved by a method for delivering at least one fluid medicament from a medical device comprising a first reservoir containing a first fluid medicament, a second reservoir containing a fluid, and a fluid element connected to said first reservoir and said second reservoir. The method comprises receiving information about a desired dose of the first fluid medicament to be ejected, adjusting said dose to be ejected from said first reservoir based at least in part on information about a content of said fluid element, and ejecting said adjusted dose from said first reservoir through said fluid element. The technical problem is further solved by a medical device configured to work according to the method.

Description

technical field [0001] The present invention relates to a method of delivering at least one fluid medicament from a medical device. The invention also relates to a medical device. In particular, the invention relates to methods and medical devices for delivering at least two medicaments from separate reservoirs. These agents may include first and second drugs. The medical device includes a dose setting mechanism for delivering the medicament automatically or manually by the user. [0002] The medical device may be an injector, such as a hand-held injector, in particular a pen-type injector, ie of the type that administers by injection of the medical product from one or more multi-dose cartridges. In particular, the invention relates to syringes in which the user can set the dose. Background technique [0003] Agents may be contained in two or more multi-dose reservoirs, containers or packs, each containing a separate (single drug compound) or premixed (co-formulated mult...
