  • Publication number: 20190223931
    Abstract: A mixing and delivery system (1) and a method for impregnating granules (G) with a liquid and for delivering a resulting mixture are specified. The mixing and delivery system (1) has a container (2) for holding the granules. In a distal end region (25) of the container is arranged a separation element (4), which is designed to retain granules but allow liquid to pass through. The container has a predefined breaking point (27) proximal of the separation element (4) so that the distal end region between the predefined breaking point and the distal container end (23) can be broken off from the container together with the separation element (4), thereby creating a delivery opening on the container for delivering the mixture.

  • 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: 20170340455
    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.

  • Publication number: 20170225191
    Abstract: A discharge device that serves the purpose of discharging at least two components from a multiple cartridge. The discharge device has a housing, a threaded rod and an advancing element with an internal thread. The threaded rod engages in the internal thread of the advancing element such that the advancing element can be pushed forward in a distal direction by turning the threaded rod in relation to the housing. In the region of its distal end, the threaded rod has a taper. Formed on the housing, in the region of its distal end, is a holding element. The holding element has a laterally open clearance, and the threaded rod is pushed with its taper laterally into the clearance of the holding element such that the holding element fixes the threaded rod axially in the housing in the distal direction and in a proximal direction opposite thereto.

  • Patent number: 9662676
    Abstract: An attachment part with a coupling part by means of which coupling part the attachment part can be attached to a dispensing unit. The coupling part has a female cone area, with a continuous inlet opening, and a locking structure arranged around the female cone area. The female cone area can be pushed onto a male cone area of the dispensing unit, in order thereby to connect the attachment part to the dispensing unit. The locking structure serves to secure the attachment part on the dispensing unit. The first coupling part additionally has a rotation element, which is rotatable concentrically about the female cone area and on which the first locking structure is formed. The rotation element has an actuating element, which serves to rotate the rotation element relative to the female cone area.

  • 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.
