  • Patent number: 10478316
    Abstract: A discharge device (1) comprising a housing (200), a container insert (300) rotatably arranged therein and a piston. A lateral cutout (205) is formed in one housing wall (204), and a lateral container opening (303) is formed in one container wall (304). In order to prevent the compound from being compressed as the compound is discharged, the lateral container opening extends continuously as far as the distal container end (302) without a region of the container wall adjoining the lateral container opening in the distal direction along the longitudinal axis. In order to make it easier to put in the compound, the wall thickness of the housing wall decreases continuously toward the lateral cutout (205). In order to prevent clogging of the piston, the cross section of the container insert widens continuously in the distal direction.

  • Patent number: 9981283
    Abstract: This invention relates to a discharge device of the dispenser gun type, which is suitable in particular for discharging semi-solid materials such as e.g. bone replacement materials. The discharge device comprises an adapter (400) which is removably attached to a main body (110) of the discharge device. A fastening structure for attachment of a container (300) is formed on the adapter substantially along a proximal direction (C) contrary to the feed direction (A). As a result various types of containers can be fastened to the machine without the need to change the mechanism of the device. The container can be provided on both ends with identical external threads and can be closed by closure caps in order to enable intuitive handling. In order to improve access to points which are difficult to reach, the container may be in the form of a curved pipe or may be formed flexibly. The piston rod (200) of the discharge device is then also formed flexibly.

  • Publication number: 20170100115
    Abstract: An applicator for spraying at least two components in the interior of the body of a patient uses a compressed gas, the applicator being suitable in particular for laparoscopic applications. The applicator has a connecting piece for connection of the applicator to two reservoirs for the components and for delivery of a compressed gas. A multi-lumen tube extends from the connecting piece to a spray head. A flexible wire is fixed in a first lumen which extends off-center. The applicator has at least one adapter having two tube connectors which are introduced into two further lumina. These two further lumina likewise extend off-center and are offset in the circumferential direction from the lumen which receives the wire. A further lumen can extend centrally and can receive a second wire. Identical adapters can be provided at both ends of the multi-lumen tube.

  • Patent number: 9402787
    Abstract: The invention relates to a device for removing a fluid from at least one container (300), from a vial for example, said container being closed by a closure (320) that can be punctured. The device comprises a base body (271) with a container receiving portion (272) and a hollow needle-like puncturing organ (277) in order to puncture the closure (320) of the container (300) in a removal position of the container (300). The aim of the invention is to enable mounting the container on the device without unintentionally puncturing the closure. This is achieved in that detent structures (274, 275) are provided which retain the container (300) on the device in a removal position and in a mounting position which is different from said removal position. Such a device can be used in particular to fill an applicator (280) with one or more fluid reservoirs from one or more vitals.

  • Patent number: 9370630
    Abstract: Proposed are a medical spray head (300) for spraying one or more fluid substances with the use of a compressed gas, a spray device equipped therewith, and a method for using the same. In order to avoid too high a gas pressure, the spray head comprises a pressure relief valve (310) which guides the compressed gas out of the spray head if the gas pressure exceeds a threshold pressure. As a result, the risk of gas embolisms occurring during the use of such a spray head for medical purposes is reduced.

  • Publication number: 20160128752
    Abstract: A mixing and discharging device (1) has a syringe-like container (10), in which a plunger can be moved. A press-out spindle (30) having an external thread (31) interacts with a counterpart (40) by means of a thread engagement. The counterpart comprises one or more thread segments, which can be deflected outward in order to release the thread engagement. A securing element (5) can be slid onto the counterpart (40) in a distal direction in order to prevent a release of the thread engagement. A mixing rod (61) extends through the plunger (20). An operating element (70) is connected to the proximal end of the mixing rod by means of a releasable form closure or force closure. A locking element (80) can be moved between a locking position and a release position. In the locking position, the locking clement prevents a release of the form closure or force closure. Insulating ribs (13) minimise the input of heat into the interior of the container due to touching.

  • Patent number: 9308506
    Abstract: A mixing apparatus for mixing at least two components comprises a mixing chamber having a first component and at least one component chamber having a further component. The component chamber is connected to the mixing chamber by a feed line. A negative pressure device generates a negative pressure in the mixing chamber in the starting position. By activating the negative pressure device, the pressure is equalized, whereby the further component is transferred into the mixing chamber. A display apparatus is provided at the component chamber to display a pressure change in the component chamber. The display apparatus is preferably formed by elastic bellows provided at one end of the component chamber, which is disposed opposite of the end of the component chamber following the feed line.

  • Patent number: 9131930
    Abstract: A filling device (300) for breaking at least one ampoule (700) and for filling a syringe (600) from the ampoule is disclosed. The filling device has a base body (310), which delimits at least one hollow space (315). At the distal end, each hollow space has a removal opening, which is connected to a port (313) for the multi-use syringe. A breaking unit is designed to break the ampoule located in the hollow space. In some embodiments, the breaking unit comprises an actuating element, which is used to slide at least two ampoules onto a wedge-shaped structure, respectively, by way of a single actuating movement in the longitudinal direction, in order to apply a lateral force on the tips of the ampoules. In other embodiments, the breaking unit comprises an actuating element (320) that can be inserted in the transverse direction and acts directly on the tips of the ampoules in order to shatter or shear them off.

  • Patent number: 8944107
    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.

  • Patent number: 8840593
    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.
