AI Technical Summary

Technical Problem

Existing dental suction devices fail to efficiently capture aerosols, air currents, and solid particles from the oral cavity without obstructing the treatment area, and passive cotton rolls require frequent replacement.

Method used

A compact, anatomically adaptable suction roller with an integrated drainage tube that actively captures aerosols, air, and solids at their source, using negative pressure and a flexible, perforated design, allowing continuous operation without obstructing the treatment area.

Benefits of technology

Efficiently removes aerosols, air, and solid particles directly at their source, maintaining a clear treatment area and reducing the need for frequent replacements.

Abstract

Suction device for use in the oral cavity, comprising an elongated, hollow roller body with a flexible wall and a plurality of perforated openings, characterized in that the roller body is connected or connectable to a drainage tube for the active extraction and removal of aerosols, fluids, air and solids from the oral cavity, wherein the geometry of the roller body for insertion into the oral cavity is designed analogously to a dental cotton roll and the drainage tube has an extraoral connection element for direct or adapter-supported coupling with different suction tube systems of a dental treatment unit, and wherein at least one safety device for receiving an external safety element to prevent aspiration is arranged on the suction device.

Description

Technical field

[0001] The invention relates to an intraoral suction device for dentistry, consisting of a functional roller body and a drainage tube connectable to it. The device serves as an active suction and mechanical spacer element for universal application in those areas of the oral cavity that are conventionally intended for the placement of cotton rolls. State of the art

[0002] The state of the art is defined by point-source saliva ejectors, passive cotton rolls, and active, surface-based suction systems. Passive cotton rolls offer tissue separation but, by design, are unable to extract aerosols, fine dust, or air currents from the oral cavity; they merely act as local absorbers for liquid secretions and must be replaced when saturated, interrupting the treatment.

[0003] Active sheet-like systems (e.g., Kulzer Ivory ReLeaf, Isolite) do allow suction via leaf-like structures, but their design often hinders instrumental access, especially in anatomically confined spaces such as the lingual mandibular space. Furthermore, unlike a traditional cotton roll, they cannot be flexibly positioned in different quadrants for soft tissue separation.

[0004] Point suction systems often fail to adequately capture dynamically generated aerosol clouds and preparation dust.

[0005] The unique feature of the present invention lies in the combination of the active extraction performance of a suction system with the compact, anatomically adaptable roller geometry. In contrast to flat masks, the roller shape allows for precise placement at the salivary gland ducts and in gravity-induced collecting areas, without visually or mechanically restricting the working field. Object of the invention

[0006] The invention is based on the objective of providing a device that combines the compact geometry of a cotton roll with a highly efficient, active extraction function. The device is intended to actively capture and remove aerosols, air, and solid particles (drilling dust, particle abrasion) directly at their source or at accumulation points, without restricting the treatment area. Description of the invention

[0007] The solution is achieved by a device according to the claims. The device comprises an elongated, hollow roller body with a flexible, perforated wall. Due to its roller shape, the device acts as an active replacement for conventional cotton rolls and, through the applied negative pressure, enables the active extraction of a wide variety of media while requiring minimal space.

[0008] This involves the immediate capture of treatment-related aerosol clouds and preparation dust directly at their source. Anatomical prevention includes the active suction of saliva immediately adjacent to the parotid papilla and sublingual caruncle. Gravitational and process-related intervention enables the continuous removal of flowing fluids as well as sliding or sedimenting solids at the gravity-driven collection points of the respective patient position.

[0009] To drain these media, the system includes a drainage tube that is either integrally bonded to the roller body or modularly pluggable. Extraorally, the drainage tube has a connection element that can be coupled either directly to the small saliva ejector port or, via an adapter, to the large-volume suction hose of the dental treatment unit. Transparent or translucent materials optimize visual inspection and light transmission. An integrated safety device enables redundant thread fixation to prevent aspiration.
