A distributor head for a distributor apparatus for distributing fluids onto a surface includes an elongate base element having a fluid volume to receive the fluid, a filling opening connected in a fluid-communicating manner to the fluid volume to fill the fluid into the fluid volume, and a plurality of distributor openings connected in a fluid-communicating manner to the fluid volume to distribute the fluid from the fluid volume. The filling opening arranged at a first longitudinal side of the distributor head and the plurality of distributor openings arranged at a second longitudinal side of the distributor head, the first longitudinal side arranged opposite the second longitudinal side, and the plurality of distributor openings continuously formed in a wall of the base element.

A common head for use in combination with a cartridge assembly, the cartridge assembly being retained within the material containment unit of a dispensing device and arranged to discharge reactive components from larger and smaller cartridges in response to actuation of the dispensing device. The common head includes inlet openings and a rigid walled tube having a partition positioned therein to define larger and smaller pathways to enable passage of the reactive components from the cartridges into and though the common head in a predetermined volumetric ratio and prevent backflow of the components which can lead to unintended curing prior to dispensing. A flexible liner arranged for positioning within one or both pathways of the rigid walled tube is also provided to prevent such backflow and unintended curing prior to dispensing.

Medical adhesive applicators are disclosed which allow medical adhesives to have long storage life and be easily dispensed in a controlled manner. In one embodiment, the applicator has a frangible glass vial with the medical adhesive. The frangible glass vial is held in a plastic enclosure with a dispensing tip. Attached to the plastic enclosure is a squeeze tube capable of imparting air pressure into the enclosure. In another embodiment, the applicator has a proximal chamber containing medical adhesive, a distal chamber for dispensing medical adhesive and one or more rupturable membranes between them. In another embodiment, an applicator pad is sized to retain the total volume of adhesive and initiator so that, in use, the entire volume of adhesive liquid is first loaded into the pad. So loaded, the adhesive and initiator mix evenly to provide an adhesive layer that cures puddle-free.

The disclosure relates to a specifically static mixer for mixing two components, with a housing, in which a mixing element is accommodated, and an input part with a first intake and a diametrically opposite second intake, wherein, within the input part, a first channel is formed between the first intake and the mixing chamber and a second channel is formed between the second intake and the mixing chamber. The first channel extends radially inward from the first intake and opens into a central opening in the cover. The second channel has two partial channels as storage chambers not leading into the mixing chamber, and two intake sections located radially within the storage chambers and leading into the mixing chamber. The intake sections branch off the respective storage chambers, extend inward in the opposite direction to the first channel and open into the central opening in the cover.

A polyurethane composition raw material liquid agent comprises a polyol or an isocyanate, and a filler. The polyurethane composition raw material liquid agent has a viscosity at 25° C. and a rotation speed of 60 rpm of 950 mPa.Math.s or less, and is filled in at least one cartridge-like container of a caulking gun that includes two cartridge-like containers and is capable of mixing two components.

An adapter for connecting a separated-outlet fluid cartridge to a single-inlet static mixer includes a locking portion and a connecting portion. The locking portion has at least one locking element to lockingly engage the mixer housing so as to inhibit rotation between the locking portion and the housing. The connecting portion is received within the locking portion and has first and second fluid inlet members to be coupled to respective first and second fluid outlets of the cartridge for receiving fluid from the cartridge, and a fluid outlet member is sealingly coupled to the mixer for directing fluid into the mixer. The locking portion is selectively rotatable about the connecting portion between unlocked and locked positions relative to the cartridge when the connecting portion is coupled to the cartridge. Consequently, the adapter advantageously enables dispensing with a separated-outlet fluid cartridge in combination with a single-inlet static mixer.

A piston for a collapsible cartridge for dispensing a material, the piston includes a rigid portion and a flexible portion. The rigid portion has a first diameter, a first end and a second end. The first end is configured to be disposed in a material dispensing direction. The flexible portion has a second diameter less than the first diameter, a first end disposed in the material dispensing direction and a second end disposed in an opposite direction. The flexible portion is disposed on the first end of the rigid portion such that the second end of the flexible portion is disposed to face the first end of the rigid portion. The flexible portion is configured to radially expand and longitudinally compress upon a force applied to the first end of the flexible portion to compress the collapsible cartridge between the flexible portion and an interior surface of a support cartridge.

A mixer including a first inlet channel, a second inlet channel, a third inlet channel, and a first dividing wall between the first inlet channel and the second inlet channel. A first opening and a second opening are formed in the first dividing wall. The mixer further includes a second dividing wall between the second inlet channel and the third inlet channel with a third opening and a fourth opening formed in the second dividing wall. The first opening is aligned with the third opening along a first axis and the second opening is aligned with the fourth opening along a second axis.

The invention relates to a delivery system, device and method for delivering biomaterials for fracture fixation (including augmented fixation), in particular, for delivery of bone cements. The mixing system ensures the biomaterial only commences setting upon extrusion from the mixer, cannula or during injection through an appropriate internal fracture fixation device, allowing for rapid closing by the surgeon. The system also permits the surgeon to cease injecting the cement for an extended period of time before continuing the injection in another area using the same cartridge, through the simple removal of one mixer and attaching another in its place. The invention also provides a method of delivery of biomaterials to a desired implantation site.

An apparatus (10) for use in dispensing adhesive (18) is provided that has a mix applicator (12) that has a receiving portion (16) and a mix applicator bore (14) through which adhesive can flow. A mix head (20) is present that has a mix head bore (26) that extends through the mix head. The mix applicator is receivable within the mix head such that the receiving portion is located within the mix head. Adhesive can be dispensed in a ribbon shape from the mix head bore at a distal tip of the mix head. A lock member is configured for extending through at least a portion of the mix head, and engages the mix applicator when the receiving portion is located within the mix head in order to retain the mix head onto the mix applicator.
