A system which has a static mixer and which contains a dental material. The static mixer has a mixing barrel that extends along a longitudinal axis and, accommodated therein, a cascade of mixing elements. Mixing elements have an outer diameter D of between 1.5 mm and 1.6 mm. The barrel has an inner diameter corresponding to the outer diameter of the mixing elements. The system helps minimizing any residual dental material in the mixer and minimizing forces for extruding the dental material through the mixer.

The sensing system includes a first input coupled to a first point on the electrical circuit, the sensing system includes a second input coupled to a second point on the electrical circuit, the sensing system is configured to determine a voltage differential between the first point and the second point, and the sensing system is configured to determine current flowing through the electrical circuit based on the voltage differential.

A water purification apparatus includes a water inlet; a medicine mixing device in fluid communication with the water inlet; and a water outlet interconnected to the medicine mixing device and a dental treatment center. The medicine mixing device includes a medicine storage for storing antiseptic solution, a mixing unit interconnected to the water inlet, the water outlet, and the medicine storage, and a controller interconnected to the water inlet and the medicine storage. The controller includes a sensor and a microprocessor. The controller sends the antiseptic solution from the medicine storage to the mixing unit and controls a volume of water flowing from the water inlet to the mixing unit. The microprocessor instructs the controller to control a volume of the antiseptic solution supplied from the medicine storage to the mixing unit based on a signal sensed by the sensor.

The present disclosure relates to a mixer having a mixer housing which encloses a mixing chamber, an input part which can be connected to the mixer housing and has at least two input openings for the components to be mixed, and a mixing element, at least some sections of which extend into the mixing chamber, wherein each of the input openings is flow-connected to the mixing chamber via at least one input duct, wherein there is also in the input part at least one compensation duct which connects the input openings to each other, and/or at least one holding chamber is provided in the mixing element.

The present disclosure relates to the field of mixing and dispensing apparatuses. A mixing and dispensing apparatus of the present disclosure facilitates automatic mixing and dispensing of a semi-liquid form of a powder material when mixed with a fluid. The apparatus comprises a mechanism to hold and rotate a cartridge, an actuation device, and an injection unit. The cartridge consists of the powder material to be mixed with the fluid. The mechanism rotates the cartridge about a primary axis of rotation and a secondary axis of rotation to uniformly mix the powder material with the fluid. The actuation device performs a piercing stroke to pierce one end of cartridge, and a dispensing stroke to dispense the semi-liquid form of the powder material through other end of the cartridge. Further, the injection unit is disposed within the actuation device to inject a pre-determined quantity of fluid following piercing stroke.

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.
