摘要:
A dose setting mechanism comprising a first element and a second element; the first element being moveable with respect to the second element; the first element and the second element being coupled by a ratchet mechanism allowing motion of the first element with respect to the second element from a first position to a second position only in a first direction while preventing motion in a second direction that is opposite to the first direction; once passing the second position, the first element being moveable with respect to the second element in the first direction and in the second direction.
摘要:
The present disclosure is generally directed to a drug delivery device for selecting and dispensing a number of user variable doses of a medicament. The device comprises a housing (10), a dose selector (80) operable to set a dose by rotation relative to the housing (10), a number sleeve (60) arranged within the housing (10) such that at least a portion of the number sleeve (60) is visible through a first aperture (11b) in the housing (10), and a piston rod (30) coupled to the housing (10) and to a drive sleeve (40). Rotation of the drive sleeve (40) relative to the housing (10) causes the piston rod (30) to translate relative to the housing (10). The piston rod (30) is coupled to the housing (10) via a threaded interface (16, 31) with at least two different pitches.
摘要:
A method for detecting a limit of use of a medical device is presented having the steps of starting a timer of a medical device when the 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 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.
摘要:
A drug delivery device with differentiating features is provided. The drug delivery device comprises a dose setting mechanism (102, 500), a cartridge holder (104, 300), and a cartridge (120, 400) contained within the cartridge holder. The cartridge holder is secured to the dose setting mechanism and comprises a collar or ring (310). The ring has the same color as other differentiation features on either the dose setting mechanism or the cartridge, or both. The color-coded ring is configured on the cartridge holder such that when the cartridge holder is assembled with the dose setting mechanism, the color-coded ring remains visible.
摘要:
A system for reducing the risk of an incorrect selection or dispensing of a drug dose for use with a cartridge and a cartridge holder so as to prevent unwanted reservoir cross use. The coding system for use with the drug delivery device includes a first partial code feature and a second partial code feature. The first partial code feature and the second partial code feature cooperate to supply a combined visual indicator when the cartridge is assembled to the holder for indicating that a correct cartridge has been assembled to the holder.
摘要:
A set of members for a drug delivery device (10) comprises at least two components for the device (10), wherein both components are provided with a marking (19, 20), the markings (19, 20) being substantially equivalent or identical. Furthermore, a drug delivery device (10) and a set of drug delivery devices (10) are provided.
摘要:
A coded cartridge holder for use with a drug delivery device is provided. The cartridge holder includes a fastener that becomes operative based in part on a length of a cartridge or a diameter of the cartridge. In one embodiment, the cartridge holder is coupled to the drug delivery device. The cartridge holder comprises a first blocking feature. The drug delivery device includes a cartridge detector comprising a second blocking feature. This feature may be a pin, for engagement with the first blocking feature of the cartridge holder when the cartridge acts on the cartridge detector. The cartridge holder may further include a fastening mechanism configured to fasten the cartridge holder to the drug delivery device only when the second blocking feature engages the first blocking feature.
