Abstract: A method for detecting at least one tool state of a tool of a machine tool for machining workpieces, which includes at least one tool holder, at least one positioning drive, which includes at least one tool which is arrangeable or arranged rotationally fixed in the tool holder and which includes at least one control unit. The method includes the following steps: detecting or providing tool and/or workpiece data in the storage means and/or the control unit; providing at least one reference drive frequency of the rotary drive and/or the positioning drive; detecting at least one ACTUAL driving frequency of the rotary drive and/or the positioning drive; assigning the ACTUAL drive frequency of a reference drive frequency of the rotary drive and/or the positioning drive by the control unit and evaluating and/or interpreting at least the reference drive frequency associated with the ACTUAL drive frequency by the control unit.

Abstract: A filling aid is provided for filling a cylinder ampule (7) with a medical or pharmaceutical fluid. The filling aid in a common housing (4) includes a first receiver (24) which is configured for receiving the cylinder ampule (7) to be filled, and a second receiver (26) which is configured for receiving a receptacle (18) containing a medical or pharmaceutical substance. A first access opening (28) is formed on the first receiver (24) and is arranged such that the first access opening (28) lies opposite an opening of a cylinder ampule (7) when this cylinder ampule is inserted into the first receiver (24). A second access opening (30) is formed on the second receiver (26) and is arranged such that the second access opening (30) lies opposite an opening of a receptacle (18) when this receptacle (18) is inserted into the second receiver (26).

Abstract: The invention relates to an applicator instrument for applying dental compounds. The applicator instrument comprises an instrument head with a support structure and with a plurality of projections formed on the support structure. The projections are elastic and, in relation to a height extent, have less stiffness than the support structure. Between them, the projections enclose a receiving space for the dental compound. According to the invention, the projections have a planar configuration and, in relation to a width extent, are arranged substantially parallel to one another. The greatest diameter of the instrument head is between 2 mm and 3 mm. With the applicator instrument according to the invention, it is easier to apply the dental compound in dosed amounts and to spread the dental compound across the surface that is to be treated.

Abstract: A syringe comprising a cylinder and a plunger arranged in the latter has a sealing element which, with a contact region, abuts an inner wall of the cylinder and seals an annular gap between the plunger and an inner wall of the cylinder. The contact region has a front section which, in the rest state, abuts the inner wall of the cylinder with an abutment pressure. The plunger is connected to the sealing element in such a way that the sealing element does not follow an initial movement of the plunger out of the rest state and such that the sealing element follows a continued movement of the plunger. The abutment pressure between the sealing element and the inner wall in the front section of the contact region decreases during the initial movement. With the syringe, less force is required in order to overcome the static friction between the sealing element and the inner wall of the cylinder.

Abstract: The invention relates to a Luer lock connection comprising a Luer cone and a threaded sleeve surrounding said cone, the threaded sleeve being fitted on the base of the Luer cone so that it is rotatable along the longitudinal axis of said cone, wherein clamping means are provided between the threaded sleeve and the base of the Luer cone, said means being designed in such a way that when a female part is fitted onto the Luer cone, clamping between the threaded sleeve and the base of the Luer cone is achieved by rotating the threaded sleeve or the female part in the threaded sleeve (4).

Abstract: A prefilled syringe includes a syringe cylinder (2), which has an open axial side, closed by a plunger, and another side closed by a Luer lock connection (4), molded on an end wall. A flowable medium (8) fills the syringe cylinder (2), a soft-elastic stopper (9) closes at least the Luer (5), and a tamper-evident closure (15) surrounds the outside of the stopper (9) and which has a predetermined breaking point. The syringe cylinder (2), the end wall (3), and the Luer lock connection (4) are formed as a single piece in the form of a transparent injection-molded plastic part. The tamper-evident closure (15) includes the same or a similar plastic as the syringe cylinder (2) and is welded to the end wall (3) of the syringe cylinder (2). The welding connection forms the predetermined breaking point, and the stopper (9) is integrated into the tamper-evident closure (15).

Abstract: A syringe with a syringe cylinder has a Luer-lock connection arranged at an axial end of the syringe cylinder. The Luer-lock connection includes a Luer cone and a rotatable threaded sleeve surrounding this. The rotatable threaded sleeve of the Luer-lock connection includes a radially outwardly directed prominence.

Abstract: A method of manufacturing or handling a substantially pure object includes shielding the substantially pure object from the environment by substantially enveloping the object in a fluid. A system for manufacturing a substantially pure object includes a mold for forming the object, and a machine adapted to remove the object from the mold. The machine includes a handling device for gripping the object and removing it from the mold. The handling device includes at least one nozzle through which fluid is delivered to substantially envelope the object during, for example, removal of the object from the mold. The object may be a medical object, such as a syringe, or a component or part thereof, such as a syringe barrel or plunger. In a preferred aspect, a molding process is conducted in a room exhibiting less than Class 100 conditions and/or in such a way that the object does not need to be subsequently cleaned or rinsed, as by air or water washing.

Abstract: The syringe is a prefillable or prefilled syringe having a syringe cylinder which is delimited to one side by a plunger and which to the other side opens into a syringe connection having a free end closed by a membrane. The syringe cylinder, the syringe connection and the closing membrane are formed as one piece as a plastic injection molded part.
