METHODS AND APPARATUS FOR REDUCING ANXIETY IN A PATIENT

Abstract

Apparatus and methods for inhibiting the odor of an anesthesia mask, and thereby reducing patient anxiety, generally comprising the use of a towelette treated with a pleasant odorant or flavorant to wipe down a piece of medical equipment, generally a piece of non-metallic or plastic equipment, such as a breathing mask, prior to it being positioned on a patient, and in a location on the patient where the odorant or flavorant can be smelled or tasted.

DESCRIPTION OF THE PREFERRED EMBODIMENT(S)

[0026] The following detailed description and disclosure illustrates by way of example and not by way of limitation. This description will clearly enable one skilled in the art to make and use the disclosed systems and methods, and describes several embodiments, adaptations, variations, alternatives and uses of the disclosed systems and methods. As various changes could be made in the above constructions without departing from the scope of the disclosures, it is intended that all matter contained in the description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

[0027] Described herein, among other things, are apparatus and methods for inhibiting the odor of an anesthesia mask, and thereby reducing patient anxiety. The apparatus and methods describes herein generally comprise the use of a towelette treated with a pleasant odorant or flavorant to wipe down a piece of medical equipment, specifically, a piece of non-metallic or plastic equipment, such as a breathing mask, prior to it being positioned on a patient in a location where it can be smelled or tasted.

[0028] FIG. 1 depicts an embodiment of a method (101) for inhibiting or reducing anxiety in a patient undergoing anesthesia. In the depicted embodiment of FIG. 1, a towelette is treated (103) with an odorant or flavorant. The towelette means a typically small and disposable paper or cloth towel. Towelettes are typically individually packaged in airtight and watertight packaging that is yet easy to tear open without the use of cutting tools. In the prior art, such towelettes are typically treated with a cleaning or cleansing agent, such as an alcohol-based anti-microbial compound, and the sealed individual packaging prevents the cleaning agent from evaporating. Thus, the towelette is typically moistened or damp when first removed from the packaging. In the depicted embodiment of FIG. 1, the towelette is treated (103) with an odorant or flavorant. This is preferably in place of a cleaning or cleansing agent, as the towelette will be applied to a new, sterilized, or clean breathing mask, which does not require cleaning or cleansing prior to use. Further, cleaning agents may also impart an unpleasant odor. However, in an alternative embodiment, the towelette may additionally be treated with other agents, such as, but not necessarily limited to, a cleaning or cleansing agent, an anti-bacterial, an anti-microbial, a dissipant, or an evaporant. This step is typically performed at the point of manufacturing, before the towelette is packaged and shipped.

[0029] Because the method and apparatus are generally used with children, the preferred odorant or flavorant is typically characterized by sweetness, as there is a memory component to the sense of smell, and a pleasant, sweet smell is more likely to calm a child by rousing fond memories. By way of example and not limitation, a fruit-flavored odorant or flavorant may be used. The precise chemical composition of the odorant or flavorant may vary from embodiment to embodiment, and it its preferred that the odorant or flavorant be suitable for ingestion or inhalation in at least small quantities. Examples include fruit-flavored or fruit-odored oils, such as glycerides. Compounds that generally cause minimal skin irritation and may be safely inhaled or ingested are preferred, to reduce the likelihood of allergicreactions.

[0030] When a patient, typically a child, is fitted with a breathing mask, typically but not necessarily as part of an anesthetic procedure, the mask is treated (105) with a towelette immediately before being fitted to the patient. This application (105) comprises wiping down the interior surfaces of the mask with a treated towelette so as to transfer some of the odorant to the interior surface of the mask. The odorant transferred to the interior surface of the mask will then begin to vaporize as dispersants, water, scent, or the oil itself evaporates. This produces a pleasant smell in the vicinity of the mask. The evaporation process may be aided by the flow of oxygen to the mask.

[0031] Next, the mask is fitted (107) to the patient. The unpleasant new plastic smell of the mask is then covered or suppressed by the stronger and fresher odor of the odorant vapor, because the odorant was recently transferred to the interior of the mask. Further, a medical breathing mask usually covers the mouth and nose and is largely enclosed, having a hose for supplying oxygen and/or other inhalants, and an exhaust hose or port for expelling respiratory byproducts. When the mask is fitted to the patient's face, the concentration of odorant vapor in the largely enclosed compartment defined by the mask interior and the patient's face will generally increase quickly, causing the patient to primarily smell the odorant rather than the mask. The rate of evaporation may be increase by the heat from the patient's respiration into the mask.

[0032] Another advantage of the use of towelettes is that the odorant and other compounds with which the towelette is treated can be spread over the mask in a thin film, rather than concentrated in aerosolized droplets. This reduces the waste inherent in aerosol sprays, and avoids the problem of larger droplets accumulating on the mask. Because the towelettes can be wiped across the mask, a thin layer can be applied, which will evaporate at a more desirable rate when fitted to the patient.

[0033] The towelette may be treated with a number of chemicals, including, but not necessarily limited to, one or more of the following: glycerin (30-60%), carboxymethylcellulose (1-5%), pentylene glycol (1-5%), sucralose (0.1-2%).

[0034] FIG. 2 depicts an embodiment of an anesthesia mask for use in the method according to the present disclosure. FIG. 2 also depicts an embodiment of a towelette for use in the method according to the present disclosure. The depicted towelette is shown individually packaged, partially unfolded, and fully unfolded.

[0035] In an embodiment, the odorant or flavorant may be one or more products selected from the group consisting of: Trigg Laboratories product code 8014-01, 21509 (Watermelon), Trigg Laboratories Product code 8012-01, 21501 (Passion Fruit Punch), Trigg Laboratories Product code 8011-02, 21608, 21503 (Kiwi Strawberry), Trigg Laboratories Product code 8018-01, 21501 (Sweet Cherry), or other similar products.

[0036] While the invention has been disclosed in conjunction with a description of certain embodiments, including those that are currently believed to be the preferred embodiments, the detailed description is intended to be illustrative and should not be understood to limit the scope of the present disclosure. As would be understood by one of ordinary skill in the art, embodiments other than those described in detail herein are encompassed by the present invention. Modifications and variations of the described embodiments may be made without departing from the spirit and scope of the invention.
