Embodiment Construction

[0041] The present invention relates to a nozzle unit 100 intended to be used as part of an oral irrigator. figure 1 Shows the manner in which the nozzle unit 100 can be applied to spray a stream 1 of flushing fluid, in figure 1 is schematically shown by arrows and is used to direct the irrigation fluid stream 1 towards the periodontal pocket in the subject's mouth. In particular, the nozzle unit 100 is placed at the position of the interdental interface 4 near the subject's teeth 2,3. The nozzle unit 100 comprises at least one nozzle orifice 5 which can simply be placed on the outside of the bag and still allow flushing fluid to flow from the at least one nozzle orifice 5 to the full depth of the bag during operation as long as the nozzle unit 100 The angle and positioning of are set such that a predetermined orientation of the flow of irrigation fluid relative to the teeth 2, 3 and the periodontal pocket is achieved. The optimal impingement positioning of the irrigation fl...

Abstract

A nozzle unit (100) for oral care is provided, comprising at least one nozzle orifice (5). The nozzle unit (100) is designed for use in an oral irrigator and has at least one construction feature, the at least one construction feature is configured to facilitate a predetermined orientation of the irrigation fluid flow (1) relative to a respective tooth (2, 3) and a periodontal pocket of the subject when the at least one nozzle orifice (5) is placed near the respective tooth (2, 3) of the subject at a location of the interdental interface (4), a pocket inflow angle from the at least one nozzle opening (5) towards the periodontal pocket is in the range of 10 DEG to 50 DEG and a surface impact angle from the at least one nozzle opening (5) towards the surface (7) of the respective tooth (2, 3) of the subject is in the range of 0 DEG to 50 DEG.

Description

technical field [0001] The invention relates to a nozzle unit comprising at least one nozzle orifice, designed to be used as part of an oral irrigator for emitting a flow of irrigation fluid directed towards a periodontal pocket in the mouth of a subject. [0002] The invention also relates to an oral irrigator comprising a nozzle unit, and to a method of performing an oral cleaning action, wherein a flow of irrigation fluid is directed towards a periodontal pocket in the mouth of a subject. Background technique [0003] The present invention is in the field of oral hygiene where the hygiene and health of teeth and gums is paramount and there is a continuing need for useful oral cleaning tools and methods. [0004] A well-known oral disease is periodontitis, which is an infection of the gums. Periodontitis is irreversible because the breakdown of the tooth's supporting tissues cannot be fully restored. This causes the gums to separate from the teeth, thereby creating a gap...
