Various embodiments for cleaning carious regions of a tooth are disclosed herein. For example, a dental apparatus can include a fluid platform having a chamber sized and shaped to retain fluid. The chamber can be configured to be coupled to the tooth over the carious region. A pressure wave generator having a distal end may be configured to be positioned in the chamber. The pressure wave generator may be configured to generate pressure waves in the retained fluid sufficient to clean the carious region.

The present invention relates to a mouth cleaning device using incoming fluid, a mouth cleaning system comprising such device and a method for using the mouth cleaning device. The mouth cleaning device comprises: a housing extending in a longitudinal direction comprising: an incoming fluid inlet; an outgoing fluid outlet; a cleaning head with an incoming fluid outlet and an outgoing fluid inlet; and a cleaning head connector configured for connecting the cleaning head to the housing, and the cleaning head connector comprising an incoming fluid channel configured for operatively connecting the incoming fluid inlet and incoming fluid outlet, and an outgoing fluid channel configured for operatively connecting the outgoing fluid inlet and outgoing fluid outlet, wherein the cleaning head connector comprises an incoming fluid connection and an outgoing fluid connection that are provided at a connection distance in the longitudinal direction of the housing.

A non-invasive dental or surgical monitoring system is disclosed. The monitoring system is comprised generally of dental or surgical equipment to be monitored, a main sensor unit, a set of sensors. The main sensor unit is in communication with various sensors removably attached to the equipment. The sensors monitor environment conditions related to the equipment rather than directly monitoring the equipment. The collected data is sent to the main sensor unit and can be accessed, or wirelessly transmitted by signal to a device or devices at another location. As collected data aggregates, a data profile can be created, machine learning can be used to discover patterns, and predictive analysis can be incorporated to help software make predictions of, or spot in real time, equipment problems based on deviations from the profile.

A medical, in particular dental-medical, fan for extracting or compressing a gaseous working fluid, in particular air, comprises a compressor unit with an outer housing, which comprises an inlet opening for the working fluid and an outlet opening for the working fluid, which are fluidically connected to one another, and which defines a compressor sector and a drive sector.

A dental suction device for suction of fluid deflections and aerosols produced by the effect of a drill or laser of a dental instrument inside the oral cavity, and attachment for removably attaching the dental suction device to the dental instrument, characterised in that the dental suction devices comprises a tubular body for suctioning fluid that forms a first outer cavity to receive a working head of the dental instrument, wherein a distal portion (B) of the tubular body extends radially so as to at least partially surround a perimeter of the first outer cavity housing the working head of the dental instrument, wherein a wall of the distal portion (B) of the tubular body incorporates at least one suction orifice.

A portable oral irrigator includes a nozzle, a handle, an outer water container and an inner water container. The nozzle is at an upper end of the portable oral irrigator. The handle is below the nozzle. The outer water container is below the handle. The inner water container is below the outer water container. A sealing ring is at a bottom of the inner water container for sealing the inner water container. An annular silicone sealing member is at a joining portion of the outer water container and the inner water container. A gasket is between the outer water container and the handle. An air passable silicone seal is on the gasket. With provision of the air passable silicone seal, a raised bottom of the air passable silicone seal contracts to close its cross-shaped opening due to water pressure in the outer water container, thereby preventing leakage.

The present disclosure relates to a pumping assembly, a piston pump and a water flosser. The pumping assembly includes: a cylinder, at least two chambers with different inner diameters being provided in the cylinder; a piston mechanism successively extending through the at least two chambers, the piston mechanism being in slidable cooperation with walls of the chambers, and a gap being formed between a sidewall of part of the piston mechanism and the walls of the chambers; and a drive mechanism connected to the piston mechanism, the drive mechanism being configured to drive the piston mechanism to move.

An oral irrigator handle including a housing and a first fitting, the first fitting including a first fitting inlet in fluid communication with a handle inlet in fluid communication with a fluid source and a first fitting outlet in fluid communication with the first fitting inlet. The handle includes a seal positioned around the first fitting and between the first fitting inlet and the first fitting outlet. A second fitting includes a second fitting inlet in fluid communication with the first fitting outlet and a second fitting outlet in fluid communication with the second fitting inlet. A bottom portion of the second fitting seats on a portion of the first fitting so that the seal engages an interior surface of the second fitting, a flow passage is coupled to the second fitting and in fluid communication with the second fitting outlet.

The shower set includes a water outlet end and an oral irrigator. A water inlet of the oral irrigator communicates with the water outlet end; to cause the oral irrigator to spray water received from the water outlet end out of the oral irrigator under the action of a water level or water pressure of the water outlet end. The technical problem in the related art of inconvenient use of an oral irrigator during showering is resolved.
