Definitions

  • the invention relates to an oral insert for delivering a substance into the oral cavity according to claim 1 and a combination of the same with a substance to be delivered into the oral cavity according to claim 15.
  • the function of the nasal mucous membranes is to moisten the air we breathe in order to avoid irritation of the throat and bronchi.
  • the invention relates to an oral insert for delivering a substance into the oral cavity, comprising an attachment area which is intended to be removably attached to an upper jaw or a lower jaw, and a chamber, which is connected to the attachment area and delimited by a wall, for receiving the Substance.
  • the chamber includes a delivery area through which the substance is delivered into the oral cavity.
  • the oral insert according to the invention thus enables the substance to be released into the oral cavity, the removable attachment of the oral insert to the upper jaw or the lower jaw allowing safe use. As a result, the substance is safely released into the oral cavity. For example, the risk of aspiration of a solid substance carrier carrying the substance can be prevented. Since the mouth insert can be safely worn over a long period of time, for example while sleeping, continuous delivery through the delivery area can be ensured. Depending on the design and properties of the delivery area, the delivery of the substance can be easily controlled.
  • the substance to be dispensed in the chamber is dispensed through the dispensing area.
  • Saliva can penetrate into the chamber, for example through the delivery area, and mix with substance, whereupon saliva and substance can flow off through the delivery area into the oral cavity.
  • the substance can also flow through the delivery area of its own accord and only mix with saliva outside the chamber.
  • the further production of saliva ensures that the mixture of saliva and substance continues so that it can be distributed into the oral cavity. For example, if the oral mucosa has dried out and a dry cough, the mixture will flow over the soft soft palate around the irritated throat and the throat wall will be constantly moistened.
  • an embodiment can be selected which is intended to be removably attached to the upper jaw.
  • a further embodiment can also be selected which is intended to be removably attached to the lower jaw.
  • the method of attachment can be chosen depending on the duration of the delivery of the substance or the type of treatment.
  • the removable attachment of the oral insert means that it is reversible and can normally be removed by the wearer of the oral insert without difficulty or special interventions.
  • the fastening can be based on a clamping force exerted by the fastening region on the lower or upper jaw, as is disclosed below.
  • suction cup effect takes place between the fastening area and the upper jaw and / or possibly the palate.
  • This suction cup effect can also be generated between the fastening area and the lower jaw.
  • the suction cup effect occurs through direct contact between the fastening area and oral tissue, in particular the gums, for example with the moistening of saliva when the oral insert is put on.
  • the attachment can take place via a pressure-sensitive adhesive which is applied over the attachment area and ensures adhesion between the attachment area and the upper jaw and, if appropriate, the palate or the lower jaw when the oral insert is put on.
  • the fastening area extends over an already existing dental implant and, if necessary, replacement teeth or an toothless area of the upper jaw or the lower jaw.
  • part of the fastening area can exert a clamping force on the upper jaw and another part of the fastening area can produce a suction cup effect together with the palate.
  • oral cavity means the space delimited by the wall of the oral cavity, which is delimited to the front by the lips, to the top by the hard and soft palate, to the side by the cheeks and to the bottom by the floor of the mouth.
  • the floor of the mouth thus forms the lower end of the oral cavity.
  • the teeth divide the oral cavity into an oral cavity located within the lower and upper dental arches, ie lingually, and into an oral vestibule located outside the lower and upper dental arches, ie buccal and labial.
  • the oral cavity is thus lingual to the lower or upper jaw.
  • the oral vestibule refers to the space between the lips or cheeks and the rows of teeth or, in the case of the edentulous, the extensions of the jawbone protruding into the oral cavity.
  • the oral insert comprises a support side facing away from the oral cavity, which in the position of use of the oral insert is essentially in contact with the oral cavity wall, i.e. with the tissue of the oral cavity and possibly with teeth, and rests on the tissue and possibly the teeth.
  • the contact side is thus facing the upper jaw or the lower jaw.
  • the mouth insert has an outer side facing away from the support side, which in the position of use of the mouth insert thus faces away from the upper jaw or the lower jaw.
  • the outside faces the oral cavity and thus comes into contact mainly with saliva and the tongue.
  • the chamber is arranged on the outside of the mouth insert. This allows easy access to the chamber without having to remove the mouth insert, for example to check the filling level of the chamber. This also helps to leave a comfortable feeling when wearing the mouth insert, because the chamber does not form any interference from edges or interfaces on the support side.
  • the chamber is preferably arranged lingual to the upper jaw or the lower jaw. Thus, the chamber can be easily reached through the tongue and saliva.
  • the chamber is lingual to the upper jaw or the lower jaw.
  • An arrangement labial and / or buccal to the upper jaw or to the lower jaw is also possible in order to adapt to such patients or if patients prefer this solution.
  • the chamber is preferably arranged buccally so that the patient can speak when speaking is disturbed only minimally, if at all, and the chamber does not cause any unaesthetic elevation in the area of the lips.
  • a buccal arrangement of the chamber enables the formation of a larger chamber, which can thus accommodate a larger amount of substance.
  • the wall is formed in one piece and integrally with the fastening area.
  • the delivery area is formed in the wall of the chamber on the outside, i.e. the wall comprises the delivery area. This allows saliva to reach the chamber unhindered and mix with the substance being released.
  • the chamber can be comfortably and easily reached with the tongue, for example in order to distribute the released substance.
  • the chamber on the contact side. However, this presupposes that the released substance can come into contact with saliva or that the released substance flow between the mouth insert and the tissue into the oral cavity in which the released substance can come into contact with saliva.
  • the dispensing area has a perforation, preferably a microperforation, or the dispensing area is formed thereby.
  • the delivery of the substance can be determined by the specific design of the delivery area.
  • the perforation of the wall forms a dispensing area that is easy to produce, and the dispensing rate can be influenced by the number of perforations and their size.
  • the perforations preferably have a diameter of 0.5 mm to 3 mm, particularly preferably 1.5 mm to 2 mm. This size is particularly suitable for solid substance carriers such as lozenges to alleviate sore throats, capsules or tablets.
  • a lozenge refers to a globule to be sucked to which flavors or medicinal products have been added.
  • a tablet refers to a drug in the shape of a small round or elliptical, at least approximately flat disc.
  • a capsule describes a drug whose solid or liquid components are enclosed in a mass of substance that is soluble in saliva.
  • a microperforation can be used for substances in solid or liquid form in order to keep the delivery rate low and to enable continuous delivery over a longer period of time.
  • the microperforations preferably have a diameter of 0.05 mm to 0.3 mm, particularly preferably 0.1 mm to 0.2 mm. This size is particularly suitable for liquid or gel-like substance carriers such as, for example, essential oils for relief suitable for sore throats, sea salt or local anesthetics.
  • the delivery area has a membrane, or the delivery area is formed by it.
  • the arrangement of the membrane allows further options for controlling the release of the substance, in particular through the selection of a selective permeability of the membrane. Thus, for example, it can be avoided that saliva penetrates the chamber while the substance can cross through the membrane.
  • the term “substance” denotes one or more active ingredients, possibly a combination of several active ingredients, the specific effect of which is sought in the oral cavity or via the release into the oral cavity in the body.
  • the substance can generally be used and manipulated via a substance carrier which contains the substance.
  • release of the substance means the release of the substance itself or, if applicable, the release of the substance together with the substance carrier.
  • the substance can be a solid, pasty, gel-like or liquid component of the substance carrier, which can also be solid, pasty, gel-like or liquid.
  • the expression pasty substance carrier is understood to mean a solid-liquid mixture which contains a high content of solids and is no longer flowable, but rather spreadable.
  • the expression gel-like substance is understood to mean a dispersion of a liquid and a solid phase.
  • the solid phase forms a network-like network in which the liquid phase resides. It is preferably the liquid phase around water or around a water / ethanol mixture.
