INTRODUCTION Over the course of this project, imm-you-nity has worked to provide innovative design solutions focused on interactive interfaces and devices to help people be more aware, in control and engaged with their health and wellness. The project aim was to design and develop a new consumer interactive product that would provide a distinct personal experience, improving the user’s management and relationship with their Health & Wellness. The project was specifically focused towards the user’s engagement with allergy conditions. Design investigation accounted for emerging technologies and how this could be applied to enhance the user’s management and interaction with severe allergies and anaphylaxis. Australia has one of the highest reported incidences of food allergies in the world with one in ten people forecasted to develop a food allergy throughout their lives. As those who obtain allergies become more and more prevalent, people are turning to technology for assitance of this issue. The client approached the team in endeavour to develop a product that could assist people with the management and treatment of severe allergy conditions of anaphylaxis. The imm- you-nity team was called upon to focus their design skills towards the ease in management and to increase community awareness of this potentially life threatenting condition. Those who live with sever allergies, or anaphylaxis, require a high level of planning, diligence and clear communication to minimise the risks of reaction and to have the right measures in place if a reaction does occur. However, having a severe allergy doesn’t mean that one should have to stop living their life in any form. This interactive product opportunity is being pursued in the purpose to assist and alleviate those who live with this risk, facilitating the leading of normal and health lives.

FINAL PRODUCT DESIGN 2.1 DESCRIPTION The Elixir device is a innovative design concept of an improved epinephrine auto-injector. The auto-injector is a medical device designed to deliver a dosage of adrenaline for the emergency treatment of life-threatening reactions caused by allergens. The device is intended for immediate administration for emergency supportive therapy to facilitate the time to seek emergency medical help. Market research uncovered the extensive issues of usability, cost and maintenance of exiting auto-injectors on the market. The Elixir design has been driven by the aim of improving these pain points and furthermore improve the users overall engagement and experience with their treatment of anaphylaxis. The main objectives that have been achieved in this design are listed below: - An improved connection between the user and product - Facilitate closer attention and care with product maintenance - Ease of use with little instruction and no room for fault - Improve cost & wastage - Alleviate stress and axiety with use - Ensure the user is aware or prompted of expiry dates - Assist with storage issues DNH603_16se2 : i-move project Epinephrine Auto-injector Zoe Avgoustakis n8607923 0.03mg Adrenaline 2.2 USABILITY DNH603_16se2 : i-move project Epinephrine Auto-injector Zoe Avgoustakis n8607923 0.03mg Adrenaline 2.3 QOI / PRODUCT ECOSYSTEM DNH603_16se2 : i-move project Epinephrine Auto-injector Zoe Avgoustakis n8607923 0.03mg Adrenaline 3. VALUE PROPOSITION The overarching objective of the Elixir design was to improve and alleviate the treatment of anaphylaxis for users in these life-threatening emergencies. The user group of the Self Aware are constistently mindful and careful in managing their allergies - however instances of will still arise in which accidental consumption or interaction with allergens lead to an anaphylactic response. The epinephrine injection is used by the user to self-administer the dosage via an automated device - relieving the user enough time to seek emergency medical attention. The product has considered the specific stages of engagement of the Self Aware user group - reflecting these values within the design of the Elixir device. Research unveiled that the Self Aware user is first engaged with products by new and advanced technology that has been integrated. Imm-you-nity harnessed the capabilities of technology to improve the firing mechanism of the injector by developing an electronic device; providing a more reliable product for the user. This advancement additionally enables an improved usability of the product to eliminate the hesitation and anxiety leading to its use. Research on the Self Aware user also unveiled that the engagement with products can be best sustained through the quality of interaction and usability. Elixir has been designed with intui- tive interactions, utilising metaphors to guide the user through its usability. In life-threatening situations, the users thoughts and attention will become scued by the rising anxiety and stress of the incident and the increasing severity of anaphylactic shock symptoms. The ease of use has been exhaustively considered in this design to improve conditions of the product usage and eliminate any confusion or fault with its use. The technological aspect of the product ecosystem was intentionally repressed, with the knowledge that this user group is most also often disengaged with products due its aspects of technology. Opportunities were acknowledged in which app interfaces could be integrat- ed into a system that could prompt users with product expiry and notify users of the state of their current devices. These avenues have been set aside for future developments of a more universal product but for this context, the technology has been kept minimal and for necessary function only. Present auto-injectors on the market are required to be renewed every 12 months. This leads to countless entirely unused product, going to waste every year due to the expiry of merely the 0.3mg of medication within. Imm-you-nity has designed the Elixir with the ability to be taken to pharmacists and have the adrenaline cartridge refilled once expired, saving wasted materials and costs and improving the sustainability of the device service.

DESIGN JUSTIFICATION The defining design decisions made throughout the development of the Elixir can be divid- ed across 3 main sectors, the Mechanism, the Form and the Usability. These decisions were reached through extensive design research and testing and the justification of these key decisions have been discussed below. 4.1 MECHANISM A direct-acting solenoid valve has been utilised in the Elixir as the driving force of the nee- dle into the upper thigh and the administer of the adrenaline. The details of this mechanism will be further explained within the the Technical Documentation sector of this report. In the aforementioned Value Proposition, the reasons were discussed as to how and why an electronic firing mechanism was first explored. Current devices utilise entirely mechanical firing methods and are consistently failing their users with needle stick injuries, lacerations, administerting incorrect dosages and above all - the pure anxiety associated with the aggressive interactions required to function these mechanisms. The Solenoid valve was cho- sen to generate a more reliable delivery of the needle without injury and also to successfully achieve the instantaneous intramuscular injection required for the 20mm depth administer of adrenaline. 4.2 FORM The electronic firing system selected also eliminated the extensive space required by me- chanical systems, allowing more freedom with the development of the product form. The egg shaped form of the device is held much more calmly in the hand of the user as opposed to other products on the market that suggest a more aggressive tight hand grip around pen shaped forms. The form reflects that the product is intuitive and does not require any ag- gresive force in its steps of use from the user. The egg shaped form of the Elixir was further selected to reflect an aesthetic metaphor of exactly...an egg. Devices that are on the market at present, have once again failed, in reflecting within the product design, the significance and importance of the device; along with the attention and care required with their management. These devices that hold adrenaline: (a) Have expiry dates that need to be monitored (b) Temperature conditions limited to between 15 and 25degrees (c) Cannot be subject to too much light These points have been successfully translated into the form of the egg of the device. A survey was conducted at the Nationswide Hospital Allergy Clinic. Of the users that visited the clinic within this period, it was revealed that only 40% of users were carrying their epi- nephrine devices at the time and of this selection 50% of these users devices were expired. Above all - the egg is also a symbol of life; this device is often the means between DNH603_16se2 : i-move project Epinephrine Auto-injector Zoe Avgoustakis n8607923 0.03mg Adrenaline life and death and it is vital that this can be reflected in the form of the product - as a direct or subconcious reminder of the importance of these products to be held on the user at all times. Whether this design decision of form be so direct and literal or perceived as somewhat gimicky, it is absolutely crucial that these devices are carried on the user at all times and the form of this product is constantly reminding the user of the attention that it requires and to be thoughtful of the conditions that it is kept in.

  • Making an Elderberry Syrup Or Elixir
    Making an Elderberry Syrup or Elixir Herbal syrups are water extractions of herbs (usually decoctions—see below) that are concentrated with a sweetener (preferably organic white sugar or raw honey). This sweetener provides a bit of nutritional support as a carbohydrate and also acts as a preservative. The concentration of sugar is particularly important when making syrups and elixirs; when in water, sugar acts as a food source for micro-organisms (especially molds and yeasts). However, at a high enough concentration, the sugar actually restricts the growth ability of micro-organisms. So we are aiming to get our syrup to be saturated enough to preserve, but not so saturated that the sugar overwhelms the liquid and causes crystallization. When preparing a syrup, one of the following ratios should be used: 1 part decoction : 1 part sweetener 1 part decoction : 2 parts sweetener I tend to follow the 1 part water : 1 part sweetener suggestion, as the 1 : 2 ratio is too sweet for me. But I have access to a refrigerator, which will also help with preservation. If you are keeping your syrup at room temperature, the 1:2 ratio is best. Syrups are a great, palatable method for delivery of herbal medicines (especially for children), and are also a great way to mask the flavor of less tasty tinctures--just combine the tincture and the syrup and you get the medicinal benefits of both. Preserving syrups with honey is also a great way to combine the medicinal benefits of the honey with the herbs that are being used. Do not give syrups preserved with honey to children under the age of one.

  • Sulfanilamide Disaster
    Sulfanilamide Disaster FDA Consumer magazine June 1981 Issue By Carol Ballentine Taste of Raspberries, Taste of Death: The 1937 Elixir Sulfanilamide Incident By the 1930s it was widely recognized that the Food and Drugs Act of 1906 was obsolete, but bitter disagreement arose as to what should replace it. By 1937 most of the arguments had been resolved but Congressional action was stalled. Then came a shocking development--the deaths of more than 100 people after using a drug that was clearly unsafe. The incident hastened final enactment in 1938 of the Federal Food, Drug, and Cosmetic Act, the statute that today remains the basis for FDA regulation of these products. Nobody but Almighty God and I can know what I have been through these past few days. I have been familiar with death in the years since I received my M.D. from Tulane University School of Medicine with the rest of my class of 1911. Covington County has been my home. I have practiced here for years. Any doctor who has practiced more than a quarter of a century has seen his share of death. "But to realize that six human beings, all of them my patients, one of them my best friend, are dead because they took medicine that I prescribed for them innocently, and to realize that that medicine which I had used for years in such cases suddenly had become a deadly poison in its newest and most modern form, as recommended by a great and reputable pharmaceutical firm in Tennessee: well, that realization has given me such days and nights of mental and spiritual agony as I did not believe a human being could undergo and survive.

  • Conformal Coating of Powder by Initiated Chemical Vapor Deposition on Vibrating Substrate
    pharmaceutics Article Conformal Coating of Powder by Initiated Chemical Vapor Deposition on Vibrating Substrate Katrin Unger and Anna Maria Coclite * Institute of Solid State Physics, Graz University of Technology, 8010 Graz, Austria; [email protected] * Correspondence: [email protected]; Tel.: +43-316-873-8970 Received: 16 July 2020; Accepted: 18 September 2020; Published: 22 September 2020 Abstract: Encapsulation of pharmaceutical powders within thin functional polymer films is a powerful and versatile method to modify drug release properties. Conformal coating over the complete surface of the particle via chemical vapor deposition techniques is a challenging task due to the compromised gas–solid contact. In this study, an initiated chemical vapor deposition reactor was adapted with speakers and vibration of particles was achieved by playing AC/DC’s song “Thunderstruck” to overcome the above-mentioned problem. To show the possibilities of this method, two types of powder of very different particle sizes were chosen, magnesium citrate (3–10 µm, cohesive powder) and aspirin (100–500 µm, good flowability), and coated with poly-ethylene-glycol-di-methacrylate. The release curve of coated magnesium citrate powder was retarded compared to uncoated powder. However, neither changing the thickness coating nor vibrating the powder during the deposition had influence on the release parameters, indicating, that cohesive powders cannot be coated conformally. The release of coated aspirin was as well retarded as compared to uncoated aspirin, especially in the case of the powder that vibrated during deposition. We attribute the enhancement of the retarded release to the formation of a conformal coating on the aspirin powder.
