Definitions

• the invention lies in the field of preventive treatment of inhalation allergies such as hay fever.
• the invention has for its object to provide an applicator which is filled with a medically inert or medically inactive agent and with use of which the associated allergic reactions do not occur, or at least occur considerably less severely.
• the invention provides an applicator, comprising: a supply container at least partially filled with an ointment for covering mucous membranes, in particular nasal mucous membranes, against direct contact with allergenic substances present in the air, such as pollen of grasses, plants, shrubs or trees, faeces of house dust mite, fine dust, for instance dust released during sanding, grinding, drilling, cutting or sawing of solid materials such as wood, plastics, metals and the like, soot, smoke or other contaminants, the ointment being a spreadable, pasty, fatty substance; and dispensing means for dispensing the ointment for use thereof such that it is applied to mucous membranes, in particular nasal mucous membranes, and thus covers these mucous membranes against direct contact with allergenic substances present in the air, such that after applying ointment to the mucous membranes a user is at least less susceptible to inhalation allergies such as hay fever.
• the applicator can further be provided with displacement
• the applicator can have the special feature that the at least one dispensing opening is situated in the peripheral wall of a tube with closed end, this tube having a diameter such that it can be inserted into the nose.
• the applicator preferably has the special feature that at least the outer surface of the tube consists of a material which is to some extent soft and flexible, for instance a rubbery material such as a soft polyurethane.
• the applicator can advantageously further have the special feature that the supply container has a manually compressible wall in the manner of a squeeze-bottle or tube. It is noted that use can also be made of a hypodermic syringe-like structure. A squeeze bottle-like structure or a compressible tube is however easier to operate with one hand.
• a nasal spray bottle the nozzle of which is inserted into the nose and whereby, as a result of compressing the bottle with a hand, a quantity of the pasty ointment according to the invention enters the nose.
• a modification of this known bottle for the ointment according to the invention in the sense that there is attached to the bottle a tube with closed end and a rounded outer side, which is solid on the inside, or at least provided with a plug, and the outer wall of which consists of two layers.
• the inner wall is closed and the outer wall comprises openings through which the ointment can be pressed outside from the flexible container when pressure is exerted on the bottle with a hand. Dispensing openings are left clear by rotating the tube and, after use, reclosed by rotating the tube back.
• a closing cap is then screwed onto the tube or snap-fixed thereon.
• the insertion tube is preferably removed from the nostril while being rotated or moved reciprocally to some extent, whereby the distribution of the ointment in the nose takes place as homogeneously as possible.
• the ointment has the special feature that the ointment comprises pasty fat.
• the ointment can have the feature that the ointment comprises oil .
• the ointment can have the special feature that the ointment comprises pasty or at least more or less solid fat and oil.
• the ointment preferably has the feature that it is free of additives such as aromatic substances, colouring agents, gelling agents and preservatives.
• the ointment can have the special feature that the fat comprises a mineral fat such as vaseline and paraffin.
• the ointment can have the feature that the fat comprises an animal fat such as beeswax and wool fat.
• the ointment can also have special feature that the fat comprises a vegetable fat such as coconut fat, mango butter, palm fat, shea butter and cacao butter.
• the fat comprises a vegetable fat such as coconut fat, mango butter, palm fat, shea butter and cacao butter.
• Said categories of fat can be applied individually or in combination with each other.
• the ointment has the special feature that the liquid oil comprises an animal oil.
• Animal oils are known in many forms and types. They are usually readily usable as constituent in an ointment according to the invention.
• an ointment is however recommended in which the animal oil is free of oil from marine animals, such as cod liver oil, whale oil or fish oil. Oil from marine animals usually emits an odour which is perceived as unpleasant by most people and is found in practice to be susceptible to decay relatively quickly. Certainly when the ointment is used on the nasal mucous membrane, it is recommended for obvious reasons that the ointment is substantially odourless, or at least does not emit any unpleasant odour.
• the ointment can also have the special feature that the oil comprises a vegetable oil, such as almond oil, avocado oil, borage oil (or bernagie oil) grape seed oil, hemp oil, jathropa oil, jojoba oil, cottonseed oil, coconut oil, rapeseed oil (or canola oil), linseed oil, macadamia oil, maize oil, olive oil, palm oil, palm seed oil, peanut oil (or arachis oil), rape oil, rice germ oil or rice husk oil, safflower oil (or thistle oil), sesame oil, soya oil, wheat-germ oil, evening primrose oil, walnut oil, castor oil (or ricinus oil) , sunflower oil, salad oil, (usually a mixture of different types of vegetable oils) .
• a vegetable oil such as almond oil, avocado oil, borage oil (or bernagie oil) grape seed oil, hemp oil, jathropa oil, jojoba oil, cottonseed oil, coconut
• fatty oils to distinguish them from so-called essential oil
• the following oils are primarily suitable, among other reasons because they are widely known, because of their wide distribution and many years of use in for instance cosmetic products: maize oil, olive oil, palm oil, sesame oil, soya oil, wheat-germ oil and sunflower oil.
• an ointment preferably has the special feature that the oil is free of essential oil, such as bergamot oil, lemon oil, eucalyptus oil, clove oil, lavender oil, olibanum oil, patchouli oil, peppermint oil, rosemary oil, sandalwood oil, orange oil, star aniseed oil and thyme oil.
• essential oil such as bergamot oil, lemon oil, eucalyptus oil, clove oil, lavender oil, olibanum oil, patchouli oil, peppermint oil, rosemary oil, sandalwood oil, orange oil, star aniseed oil and thyme oil.
• the ointment has the special feature that it comprises less than 5% by weight, preferably less than 1% by weight, of water.
• a specific embodiment of the ointment has the special feature that it comprises juice of aloe vera.
• Aloe vera is a plant whose juice, according to diverse publications, has a certain cooling and soothing effect when applied to the skin. When applied in the ointment according to the invention this property could have a favourable effect in addition to the covering effect against contact with allergenic substances.
• the ointment is preferably embodied such that the ratio of fat and oil is chosen such that the ointment is persistent at a temperature of use of about 25-38 0 C.
• the term 'persistent' is understood to mean that the ointment forms a good cover layer for a longer period of time and, other than in the case of for instance less viscous substances such as more oleaginous substances and gels, does not tend to release and migrate as a result of for instance gravitational force.
• the ointment according to the invention does not have these adverse effects. If a hay fever reaction occurring in unprotected conditions does not occur when the ointment according to the invention is used, the associated symptoms, such as sneezing, swollen nasal mucous membranes and itching and tearing eyes, do not appear either. It is therefore possible to continue breathing through the nose, since it is not blocked by the swollen nasal mucous membranes .
• Covering the nasal mucous membranes with the ointment according to the invention can thus prevent the swelling of the mucous membranes in the nose in reaction to contact with an allergenic substance.
• This also makes the use of this ointment suitable for patients with bronchial disorders who have allergic reactions to the most diverse substances present in indoor- air. These include the finely distributed substances as specified above.
• the nose has a mechanism for purifying the air to be inhaled. When a patient is forced as a result of the swelling of the nasal mucous membranes to breathe through the mouth, contaminants and (other) allergenic substances are no longer removed from the inhaled air, which is very undesirable from the air cleaning viewpoint. Particularly for patients with allergic asthma or COPD, preventing these substances from penetrating into the bronchi via the mouth is essential in limiting allergic reactions as far as possible.
• the irreversible damage which allergic reactions can cause to the pulmonary tissue can already be demonstrated at very young age. Because these patients usually begin to breathe through the mouth because breathing through the nose is made difficult by the swollen nasal mucous membranes, the allergens enter the bronchi directly. By covering the nasal mucous membrane with the ointment the nasal mucous membrane will not come into contact with, and so not be able to react to, the allergens present in the air, so that the patient can continue to breathe regularly through the nose. On their way through the nose at least a substantial part of the allergens will remain behind in the ointment. The quantity of allergens which can enter the bronchi directly will hereby decrease very considerably, and can even be reduced to completely harmless proportions .
• the ointment according to the invention is composed such that particularly the nasal mucous membranes are only covered, so as it were a 'mechanical' treatment, and preferably such that none of the constituents can cause an allergic reaction in a user.
• composition per se is not very specific or not specific to the effect of the ointment. What is important is the 'covering' function.
• ointment For use as prevention against hay fever it is sufficient to cover the nasal mucous membranes with ointment before the user goes outside, where contact with allergens can occur. For indoor use, it is recommended to apply the ointment when getting up, and the ointment is preferably removed when going to bed.
• the removal of the ointment takes place in the same way for both indoor and outdoor use.
• the nose must first be gently blown and thus cleaned.
• the residue of used, and thus contaminated, ointment must then be removed, for instance with a wad of cotton wool or a cotton swab soaked in oil.
• Making use of an oil-soaked cotton swab prevents the hypersensitive nasal mucous membranes becoming too dry, and therefore becoming irritated again, during the period that they do not need to be protected, such as during the night.
• the cleaning with the oil-soaked cotton swabs can prevent this drying-out to at least some extent. If desired, ointment can also be applied once again for the night.
• Cotton swabs with a quantity of ointment thereon and ready for once-only use are, as a disposable, also practical from the viewpoint of hygiene.
• cotton swabs can be used which are for instance soaked in the same type of oil as the oil included in the ointment.
• the invention is not limited to a specific composition or percentages of the solid or pasty fat relative to the oil. It is possible to envisage a proportion of about 25-30% of oil with the addition of fat to 100%.
• Pasty or at least more or less solid fats obtained from petroleum are probably to be recommended because, in contrast to the fats of vegetable and animal origin, they are not absorbed through the skin and the mucous membranes of the nose.
• the solids from petroleum are absolutely free of germs in purified form and are readily tolerated by almost everyone.
• a drawback is the possibility of a so-called ⁇ paraffin addiction' and the tendency of the skin to become dry.
• the addition of a certain quantity of oil to the solid or pasty fats considerably reduces the possibility of a paraffin addiction occurring and drying of the skin or the mucous membrane.
• the correct spreadability, in combination with the desired persistence, can also be realized by adding oil to the fat.
• Vaseline can withstand the action of chemicals and can form a barrier function relative to the skin and mucous membranes of the nose.
• Determined solid fats such as wool fat, coconut fat, mango butter, shea butter and cacao butter are probably not individually suitable because they have too low a melting point. Due to the increase in temperature through contact with the skin they become considerably more fluid, whereby the covering protective layer will tend to disappear under the influence of gravitational force. These fats are therefore individually less suitable due to their lack of persistence in conditions of use. Determined substances can however be added to these fats in order to increase the melting point and improve the persistence at a temperature of use of about 25-38°C. Vaseline, paraffin, beeswax and palm fat, among others, must be heated in order to cause them to melt. The melting range lies sufficiently above the temperature in the nose. It is also possible to make a combination of for instance vaseline, beeswax and sesame oil, as well as an almost unlimited number of other combinations .
