摘要:
An atomizer (1), in particular an MDI, comprising a counting device (12) is proposed. By way of a guide track (27) and an inclined plane (28) and an associated guide element (23), an axial movement (A) is partially converted to a rotational movement for driving a counter ring (14) when the atomizer (1) is activated, wherein an annular and rigid drive element (17) comprising an axial cogging (18) is used. This allows simple and functionally secure setup, wherein even incomplete activations are counted.
摘要:
A practically diffusion-tight container which is capable of being stored over long periods of time and with which the liquid does not come into contact with the ambient air is required for withdrawing a liquid in a dosed manner out of the same over a duration of several months. The inventive cartridge is a container which is comprised of three shells and which can consist of a collapsible bag containing the liquid, of a dimensionally stabile container, and of a stiff metal shell. The cartridge can be detachably connected to a withdrawing device. The cartridge can be provided with a micro-opening with which the time for the pressure compensation between the cartridge and the surroundings can be adjusted. The cartridge is suited for aqueous and alcoholic liquids which contain a pharmacologically active ingredient. The liquid in the cartridge is protected against external influences. The cartridge can be used in an atomizer for generating an aerosol which can be inhaled and which is provided for treating illnesses.

According to the invention, film bags are used as primary packaging for liquids and permit the liquid to be withdrawn without considerable exertion of force. The invention provides a container for a medicinal liquid which is both gas and liquid tight and which can be stored for many months. The container is comprised of a collapsible film on which a dimensionally stable flange (12) is attached. The flange is designed so that it can be attached onto a dispensing support (67). The container can be situated in a dimensionally stable sleeve (142). The medicinal liquid does not come in contact with air and is protected against the effects of light. The medicinal liquid can be withdrawn from the film bag, for example, in many partial quantities over a long period of time, whereby each partial quantity is reduced into an aerosol by means of an atomizer.

A device for triggering a mechanical switching process in inhalers in synchronicity with breathing has a membrane-like sensor element (47) that cooperates with a triggering mechanism (45, 46, 50) on a switching device (13, 19c, 22).
摘要:
In an atomizer (1) for dispensing a defined amount of a fluid (2), in particular one containing a pharmaceutical, as aerosol through a nozzle (12) from a pressure chamber (11), wherein a mechanical pressure generator (5) acts on the measured fluid (2) in the pressure chamber and is abruptly released for the atomization, a nosepiece (19) is assigned to the nozzle (12).
摘要:
Dual containers, consisting of an inner container (2) and a diffusion-tight outer container (1) are used for medical fluids. The inner container collapses when the fluid is removed. A pressure-compensating device is required to compensate the pressure between the gas chamber (15) that is located between the inner and outer container and the surrounding area of the dual container, whereby the loss of fluid is kept to a minimum by diffusion from the collapsible inner container. At least one duct (7) that links the gas-filled space to the surrounding area of the dual container is used for this purpose. The time constant for compensation of a pressure differential of several millibars is several hours. This is achieved by selecting the length of the duct and cross section thereof. The at least one duct can be produced individually or a plurality of ducts can be provided in the form of pores in an open-pored sintered material or a permeable membrane. The pressure-compensating device enables the dual container to be stored for years and, if the fluid is removed in portions in a correct manner, it can be used for several weeks. During these periods, the amount of liquid in the inner container or the concentration thereof varies substantially less than if a dual container known per se is used.

摘要:
The invention concerns a holder in which drug capsules can be inserted and securely held, the holder consisting of a plate (2) with a cavity (1) in which at least three ribs (3) are disposed parallel to the central axis of the cavity at unequal intervals round the wall of the cavity in such a way that the top and bottom of the capsules can be clipped between the ribs (3) so that they do not fall out during normal handling of the holder but they can nevertheless be removed from the holder without any difficulty.
