  • Publication number: 20110278375
    Abstract: A discharge apparatus for discharging a product having compressed gas support comprises a container (1) having a discharge opening (12) and a pressure element (2), which is mounted displaceably in the container (1). A counterpressure element (13) is provided on the container (1) and is used to advance the pressure element (2) into the container in order to absorb a developing counterpressure when pressure is applied onto the pressure element (2). A compressed gas device (5, 7, 8) dispenses compressed gas in the region of the discharge opening (12), and comprises a valve (6) and a valve actuating device (14) to control the compressed gas dispensing. The actuating device (14) is provided on the counterpressure element (13) to ensure that when discharging the product from the container, at the same time the compressed gas device can be actuated by applying pressure onto the pressure element, whereby compressed gas exits the discharge opening at the same time as the fluid product.

  • Publication number: 20110253806
    Abstract: A spraying device having a spray head for spraying at least one component comprises at least one substance component duct (6, 6?; 20), the component outlet (8, 8?; 23, 23?) of which leads out of a spray head tip (7). An annular duct (12) for a pressurized gas surrounds the at least one component duct (6, 6?; 20) at least partially in the longitudinal direction and leads out of the spray head (5) at the spray head tip (7). A pressurized gas supply duct (13) is provided for introducing pressurized gas at the annular duct (12). The annular duct (12) has a plurality of ribs (16, 16?), which divide the annular duct (12) at least in the region of the spray head tip (7) into pressurized gas outlet ducts (17, 17?) that are separated from each other.

  • Patent number: 8038651
    Abstract: The suggested device comprises a dispensing piston that is actuatable by a pressure medium for dispensing a syringe and a guide portion within which the dispensing piston is displaceably supported. The device is designed for dispensing a double syringe and includes a handling portion for receiving the pressure medium, the dispensing piston, and the guide portion, as well as locking means that are releasable by applying manual pressure to the handling portion and are arranged on the handling portion and operatively connected to locking means provided on the dispensing piston. This allows a very simple repeated use of this arrangement for self-dispensing by patients, and remote wounds, e.g. an arm or foot wound, can also be treated by the patient independently.

  • Publication number: 20110114212
    Abstract: An opening device for opening a closed fluid container comprises a housing having a first chamber (1) for receiving the fluid container (3) and a second chamber (2) having an outlet (13). A part (6) of the fluid container that can be separated is arranged in the second chamber. A rotary drum (8) is rotatably supported in the second chamber. Said drum can be rotated from a starting position into a separating position in which it separates the separable container part from the fluid container. The rotational axis of the rotary drum is disposed at an angle to the connecting axis between the first and second chambers. A system for mixing at least two components uses such an opening device and a mixing container (18) having a connecting piece (19), to which the opening device is removably connected to establish a fluid connection.

  • Patent number: 7938296
    Abstract: A two-component syringe is provided with a valve assembly having a common inlet/outlet, the valve assembly being designed to selectively close the containers of the syringe or allow a liquid from the outside to be aspirated into one of the containers via the common inlet/outlet or connect the two containers to each other or allow a mixture to be dispensed through the common inlet/outlet. This valve assembly is composed of a valve body provided with a sealing disk having channels that are arranged such that the connections are established or interrupted when the valve body is rotated. The design of such a valve assembly is simple and cost-efficient, and it allows aspirating liquids into a container and transferring them to another container that holds a powder as well as dispensing multicomponent liquids or pastes efficiently and with minimum pressure and volume losses.

  • Patent number: 7736049
    Abstract: The device for storing, mixing, and dispensing components is provided with means for mixing (6) a first component (27) with a second, liquid component (28) and for dispensing the mixed materials. The individual components (27, 28) are stored in respective containers (2, 3) that are arranged side by side, and a valve assembly (8) is arranged in the transfer area (7) between the outlet area (26) of the container (3) for storing the second, liquid component (28) and the liquid inlet (25) of the container (2) for storing the first component (27). Such a device allows an unproblematic storage of the different components without a local separation of the containers and an efficient mix thereof. This applies especially if the first component is a powder or a granular or porous substance, e.g. bone cement or bone replacement material.

  • Publication number: 20090302060
    Abstract: The dispensing appliance for a multiple cartridge or syringe comprising a housing configured to receive the cartridge that has an internal thread and a rotatable portion that has a complementary thread, the internal thread and the rotatable portion cooperating in such a manner that by mutual rotation thereof, the rotatable portion is continuously displaceable relative to the housing in the dispensing direction. The housing is configured to receive the cartridge that has two adjacent storage containers, and a thrust force of the rotatable portion is transmitted to a multiple ram without any pressure relief. This arrangement allows dispensing even highly viscous materials from cartridges with little manual force under high pressure and in a precisely metered manner.

  • Publication number: 20080056065
    Abstract: The static mixer for two components comprises a housing with an inlet section and mixing elements that are arranged in the housing. At least one of the mixing elements is designed, in contrast to mixing helixes of the prior art, as a disk-shaped shear plate having a passage in its disk. Such shear elements allow mixing even of smallest quantities that are possibly dispensed drop by drop, as higher shearing rates are produced near the passages of the shear plates during dispensing and vortices are created on their outlet sides. This is very advantageous especially in medical applications of such mixers.

  • Patent number: 7325995
    Abstract: The applicator for a double cartridge includes an adapter for connection to a mixer attached to a double cartridge as well as a dispensing slot, the side of the enclosure that is turned towards the glued substrate forming an angle with the longitudinal axis of the adapter which is comprised between 5° and 90°. The underside of the enclosure is essentially continuously curved. Due to the curvature of the enclosure, the material that is to be glued, e.g. lung tissue, is first smoothened and immediately thereafter evenly coated with adhesive. This allows a reliable application of such an applicator in medicine or in the industry.
