A method for the preparation of pharmaceutical products is provided that utilizes a machine having a containing liner, a dosing chamber for preparing at least one pharmaceutical product accommodated within the containing liner, and a pneumatic ventilation device for feeding two air flows through the dosing chamber and through the containing liner, respectively. Operation of the pneumatic ventilation device is selectively controlled so that the containing liner has inside a pressure lower than a pressure existing within the dosing chamber and than a pressure existing in the environment outside the containing liner itself.

The present disclosure concerns a ventilation system to be applied to a micronizer, in such a way that the ventilation does not prevent nebulization, rather it disperses it in an environment that for example is to be sterilized. Thanks to a particular configuration, the ventilation system is also resistant to water present in the environment to be sterilized.

The invention focuses on a device for sequentially introducing additives in a polymer granulate and the use of the device for mixing the polymer granulate with the additives. The device consisting of a mixer with housing, comprising at least one mixer shaft attached in helix arranged non-continuous conveying pattern shapes, being rotated by a drive for the transport, whereby the mixer in the housing featuring an inlet for the polymer granulate to be mixed and each of the several subsequent inlets for the additive is followed by an outlet for the polymer granulate mixed with the additive, so that two or several mixing zones being formed in the mixer and whereby at least between at two mixing zones on the surface of the mixing shaft one section featuring a continuous screw conveyor instead of the non-continuous conveying pattern shapes, the section not being penetrable for returning solids from the subsequent mixing zone.

The present invention is a dust shield device that secures over a mixing pail. Powdery material, such as plaster, cement, grout or the like, is poured through the device, and mixed with water inside the pail. The device includes a mounting sleeve, a radial manifold housing and a funnel shaped lid. The manifold housing and lid form a radial pneumatic channel with a circumferentially disbursed air intake that generates a radially uniform airflow that draws in airborne dust that would otherwise escape to the surrounding air. The manifold is connected to a vacuum with an air filter, and generates a dust shield zone and air intake zone above the device. The manifold lid forms a radial guard to prevent downward flows of material and water from entering the manifold, and forms a splash guard to retain upwardly projected splashes of material and water inside the pail.

A system for bone cement includes a vial holder configured for receiving a vial and including a holding structure for maintaining the vial in the vial holder. The vial includes a monomer component for bone cement. A holder chamber is configured to receive and secure the vial holder. The vial holder is advanced toward a vial-breaking device for breaking the vial and releasing its contents into the holder chamber past the elastomeric seal. Once the vial holder is advanced further the elastomeric seal is deformed to form a seal and prevent fumes produced from escaping from the device.

A static mixing tip includes a static mixer, a housing and a body. A head space is between the housing and the static mixer, a sealing lip on the base of the static mixer seals between the base of the static mixer and the housing, and a venting element is on the sealing lip of the static mixer or the housing. The venting element provides gas flow communication between sides of the sealing lip, and a gaseous connection between the head space and an exterior ambient atmosphere such that gases trapped in the head space between the housing and the static mixer can escape during normal operation and operation of the static mixing tip.

The invention relates to a method for producing a bone cement with a device comprising a cartridge (1) having a cylindrical interior (2), cement powder (6), and monomer liquid (7) in a monomer liquid container (8), a cartridge head (3) having a discharge opening (9), a closure (10) in the discharge opening (9), which closure is permeable to gases and impermeable to powder particles, a drive piston (5), and a central piston (4), wherein the central piston (4) is permeable to gases and the monomer liquid (7) and impermeable to the powder particles of the cement powder (6) and is arranged between the drive piston (5) and the cartridge head (3), wherein the central piston (4) separates the interior (2) into a first cavity (12) and a second cavity (14), the method comprising the following steps:

A) moving the drive piston (5) toward the cartridge head (3),
B) opening the monomer liquid container (8) via the movement of the drive piston (5) and releasing the monomer liquid (7) in the second cavity (14),
C) expelling residual gases into the surroundings of the device by means of the movement of the drive piston (5),
D) injecting the monomer liquid (7) through the central piston (4) into the cement powder (6),
E) displacing gases between the powder particles with the inflowing monomer liquid (7),
F) wetting the powder particles of the cement powder (6), and
G) depressurizing the second cavity (14), wherein the depressurization takes place by partially removing the contained monomer liquid (7).

The invention also relates to such a device for mixing a bone cement, with a depressurization device (16).
