An indicating device for a dispenser that dispenses metered dosages of a medicament from a container having a valve moveable between a closed position and an open position. The indicating device includes an indicator housing having a first cover with a first vertical wall and a second cover with a second vertical wall. One of the first or second covers includes a base defining a lower surface of the indicator housing, and the other of the first or second covers includes a top defining an upper surface of the indicator housing. The first and second covers are joined with the first and second vertical walls and the base and the top defining an interior space therebetween. An indicator is rotatably disposed in the interior space of the indicator housing, with the indicator including dosage indicia. A dispensing device includes a dispenser housing and an indicating device.

A dose counter for counting doses of medicament dispensed by or remaining in a metered-dose inhaler. The dose counter includes: a rotatably mounted gear wheel having a circular arrangement of ratchet teeth; a display coupled to the gear wheel, the display having a visible array of dose counting indicia indexable in response to rotary motion of the gear wheel; and an actuator mechanism having a driver for rotatably driving the gear wheel in response to the dispensation of a medicament dose, the driver being arranged to engage the ratchet teeth of the gear wheel. The actuator mechanism includes a pivotally mounted lever having an input portion. The lever is arranged to amplify a linear stroke at the input portion such that a linear stroke of the driver exceeds the linear input stroke. By amplifying the stroke, the risk of undercounting due to insufficient stroke length may be reduced.

Dispensers, in particular dispensers for dispensing a dose of a gaseous, gas borne or droplet substance from a substance source and dispensers containing dosage counters are described herein.

A limit value detection device for multiple detection of a limit value event has a catch mechanism manufactured using microstructuring technology, having a first and a second catch element, each having a plurality of catches, a pawl configured to engage in a catch intermediate space between two adjacent catches of the first catch element, the first catch element being movable relative to the pawl in a freewheeling direction and movement thereof relative to the pawl in a blocking direction being blockable by the pawl, and an actuating device configured to move the first catch element and the pawl relative to each other in a catch-by-catch manner in the freewheeling direction. The first and second catch elements together form a counting unit in which the counter status for indicating the detected limit value events is determined based on the position of the two catch elements relative to each other.

A manipulator assisting device includes a manipulator assisting device main body connectable to a proximal end portion of a manipulator with the proximal end portion attachable to and detachable from a medical device, the manipulator having a driven gear that engages with a gear in the medical device when connected to the medical device, and an end effector that operates by a power transmitted from the driven gear. The manipulator assisting device main body includes an assisting gear that engages with the driven gear when the manipulator assisting device main body is connected to the manipulator, a handle that transmits a drive force to the assisting gear, and a main body portion attached to the assisting gear and the handle.

Embodiments of the present disclosure provide an electrical cabinet. The electrical cabinet includes a frame; a mating assembly disposed on the frame; a drawer assembly including a fixing part disposed on the frame and a movable part connected to the fixing part, wherein the movable part is pushed in or pulled out relative to the frame; and a counter connected to the movable part and including a rotating arm adapted to be driven by the mating assembly to switch between an initial position and a counting position during a process of the movable part being pushed in relative to the frame.
