Definitions

  • An accessory to be secured onto the interior of a face respiratory piece such as a face mask, respiratory device or respiratory protective device, enabling it to offer muiti functions thus performing as a specialty face mask, enhanced respiratory device or enhanced respiratory protective device.
  • Face respiratory pieces such as face masks, respiratory device or respiratory protective devices are often used e.g. in hospitals, medical clinics and even in the public when a person is not feeling well. Often the user finds the face mask or respiratory device or respiratory protective device alone cannot be sufficient in meeting his health needs which may include relief of his medical condition or enhanced protection against infection from others.
  • Face Respiratory Piece the face mask, respiratory device or respiratory protective devices
  • face Respiratory Piece Such face respiratory devices thus imbued with other functions are speciality face mask/enhanced respiratory device/enhanced respiratory protective device and referred herein as " enhanced Face respiratory pieces ".
  • the release of chemicals/ biological agents/ antiseptic drugs/ relief medicine is passive, i.e., the continuous release of active materials over a time period; the wearer is unable to intervene in the release process by controlling the intensity of the chemical/ medicinal/ bactericidal effects.
  • stick-on a multi function stick-on accessory
  • face respiratory piece such as face mask, respiratory device or respiratory protective device
  • the multi-function stick-on houses a determined amount of chemicals/ biological agents/ antiseptic drugs /relief medicine, which can be released directly from the face respiratory piece into the wearer's mouth and nose to deliver designated functions (not exhaustive). Depending on the type of chemicals/ biological agents/ antiseptic drugs / relief medicine, such functions (not exhaustive) could be for-
  • sickness relief e.g., flu, cold, cough
  • malodor reduction or removal e.g., breaks down offensive smells and nauseous gases
  • habit control e.g., anti-smoking treatment
  • Such a multi function stick-on is simple to use and at the same time improve the performance of a normal face mask by enhancing its use as a specialty face mask, enhanced respiratory device or enhanced respiratory protective device, delivering better performance and yet overcoming most of or all the aforementioned problems encountered by previous specialty face masks.
  • the present invention also describes novel methods to make the stick-on perform multi-function roles, depending on the contents contained therein, all of which offer the following properties :-
  • the present invention therefore allows a normal face mask/respiratory device/ respiratory protective device to be equipped with additional functions; thus with the use of the multi function stick-on on a face respiratory piece, the face respiratory piece is turned into a specialty face mask/enhanced respiratory device/enhanced respiratory protective device.
  • the normal face mask when used with such a stick- on of the invention is more value-added and offers the wearer more benefits and protection at a lower cost, apart from being a normal face mask/respiratory device/ respiratory protective device.
  • the type of face respiratory piece for which the stick-on could be used on includes normal face masks, the " pouch mask “ by Megatech Scientific Pte Ltd, the “ cone mask “ by 3M, the " duckbill mask “ by Kimberly Clark, and the " arch mask” by Alpha Pro Tech and other types of respiratory device or respiratory protective device not specifically mentioned herein.
  • the inventors can opt to make a sophisticated specialty face mask with added functions in the form of container containing some form of medication/chemical/antiseptic drugs/relief medicine/biological agents, but
  • the inventors have also considered making the specialty face mask from a planar face mask but the fittings of the planar face mask around the wearer's face is not tight- fitting and could lead to leakages of substantial amount of air/gas/medication/chemical/antiseptic drugs/relief medicine/biological agents (in the form of vapor).
  • the facial area of the wearer covered by the planar mask is also not wide enough to offer complete protection from spilling liquids and chipping solids.
  • the inventors have thought of making a specialty face mask by adopting a hard mask approach (e.g., full face, glass shield with canned screw-in cartridges, etc worn by fire-fighters, special military forces) but
  • the mask will be harder to package because it is one solid piece; (4) the mask will take up considerable storage space because it is not foldable.
  • a second objective for the invention to produce a low cost stick-on for a face respiratory piece which can contain different types of chemicals/ biological agents/ antiseptic drugs / relief medicine in the form of a volatile substance and which can be selected by the user, for inhalation, performing such functions as to suit the user's requirements including medical treatment (e.g. asthma); sickness relief (e.g. flu, cold, cough); malodor reduction or removal (e.g. breaks down offensive smells and nauseous gases); therapeutic (e.g. aromatheraphy) and habit control (e.g. anti-smoking treatment).

  • the designated thickness of the volatile substance ensures a certain delivery of chemicals/ biological agents/ antiseptic drugs / relief medicine over a pre- determined time span, T.
  • the direct release of chemicals/ biological agents/ antiseptic drugs/ relief medicine into the void between the inner side of the respiratory face piece and the wearer's mouth and nose is more effective in delivering the said chemicals/ biological agents/ antiseptic drugs/ relief medicine.
  • the stick-on is disposed after the volatile substance in the form of chemicals/ biological agents/ antiseptic drugs / relief medicine is fully depleted and a new stick-on secured to the interior of the respiratory face piece.

  • the adhesive cover film (26) could be made of say, four rectangular strips. The user can peel off the first rectangular strip for use of the first hour, peel off the second rectangular strip for the second hour and so on.
  • the porous net-like material (28) which can be either plastic/fabric, is needed to hold the volatile substance in place. It is porous so it does not hinder the release of volatile contents into the void between the face respiratory piece and the wearer's face.

Abstract

Accessoire adhésif multi-fonctions (22) destiné à être utilisé avec un appareil respiratoire facial (20) pourvu d'une face interne sur laquelle l'accessoire adhésif multi-fonctions est fixé, la face interne de l'appareil respiratoire facial et la bouche de l'utilisateur formant un espace vide, en vue de la libération d'une substance volatile (30) devant être inhalée par l'utilisateur. La substance volatile, qui peut être un produit chimique sublimable, un agent biologique, un médicament antiseptique ou un médicament curatif, se trouve sur une base (32) d'une couleur différente de la substance volatile de façon à ce que la base colorée devienne visible lorsque la substance volatile est épuisée, indiquant qu'il faut remplacer l'accessoire adhésif. Le taux de libération de la substance volatile peut être contrôlé par l'utilisateur. L'appareil respiratoire facial peut être un masque, un appareil respiratoire ou un système de protection respiratoire.
