Abstract
Description
1 TARIFF TECHNICAL FIELD This invention will improve patient comfort using oxygen masks in the medical sector. An innovative 5 that aims to develop it in a way that will offer environmental and economic advantages. It is related to oxygen mask design. STATE OF THE ART The oxygen masks currently in use are generally made of PVC, and this material... It is not produced in our country and is obtained through imports. Furthermore, some 10% of PVC... Various types may have toxic effects. On the other hand, classic designs prioritize patient comfort and... The fastening efficiency is insufficient. ANNOUNCEMENT OF THE INVENTION This invention aims to make patients more comfortable during oxygen therapy and to allow the mask to be 15 It is a dual-color oxygen mask developed to make it easier to use. The mask, PP (Polypropylene) and TPE (Thermoplastic Elastomer) are two safe and durable plastics. It is produced using raw materials. The mask's rigid main body is made of impact-resistant and transparent PP material. This has been done so that the mask both maintains its shape and conforms to the patient's face and breathing. It can be easily observed by healthcare personnel. The edges of the mask that come into contact with the face are made of flexible and soft TPE material. This material does not harm the skin, does not cause irritation, and is latex-free, therefore it is 25. It reduces the risk of allergies. This, in turn, increases the patient's comfort, especially with long-term use. Thanks to the mask's dual-color design, it's easy to see if it's being worn correctly. The color difference speeds up the checks by healthcare professionals and reduces usage errors. The holes on the sides of the mask allow excess oxygen and carbon dioxide to escape. This ensures proper air circulation and prevents respiratory problems. 30 2 The product design also includes elastic bands that ensure the mask is secured to the patient. The mask features perforated connection points through which it can be threaded. These holes allow the mask to be worn across various face shapes. It helps to adapt to the dimensions while preventing slipping and loosening during use. It reduces the risks. Thanks to this unique structure, the mask is made with raw materials suitable for domestic production. It can be produced economically and is also more sustainable compared to existing imported products, 5 It provides a safe and comfortable alternative. This product is used in hospital clinics and emergency rooms. for patients receiving oxygen therapy in wards, intensive care units and at home It is usable. Therefore, it is applicable across a wide range of the healthcare sector. A user-friendly and functional medical product is offered. The main advantages are as follows: • Cost advantage and faster supply thanks to domestic production of materials such as PP and TPE. This provides an opportunity. This supports production continuity and reduces external dependence. • PP and TPE materials used as replacements for PVC contain harmful chemicals such as phthalates and BPA. It does not contain; minimizes the risk of allergic reactions and, thanks to its biocompatible structure, 15 It does not harm human health. • Environmentally friendly and recyclable structures make this product suitable for sustainable medical production. makes it suitable for. • The dual-color design makes accurate placement easier and helps healthcare professionals... It enables quick visual inspection. 20 • Soft TPE areas that come into contact with the skin prevent skin irritation even with prolonged use. These preventative measures improve patient comfort and usage time. • The rigid PP body ensures the mask retains its shape during transport and use. It prevents deformation. • Thanks to the ventilation holes, excess oxygen and carbon dioxide are efficiently expelled. It is expelled, and respiratory balance is maintained. • Elastic fastening points ensure the mask fits securely to the face; different It easily adapts to different facial features. The production characteristics of the invention are as follows; 30 3 Today, standard oxygen masks are generally produced by injection molding. It is produced using this method. In this method, the mask body and the parts that come into contact with the skin are made from a single piece. It is made of the same material, and the plug that connects the mask to the hose is molded separately and then... They are assembled through a process that increases the number of parts and requires additional post-production assembly. It requires the following procedures. 5 This invention, however, utilizes overmolding, a more advanced and integrated production method. Overmolding technology is used. The rigid body part of the mask is formed using the overmolding method. It is first molded with PP (Polypropylene) raw material, and then a second layer is placed on top of this body. In one stage, soft TPE (Thermoplastic Elastomer) material is molded. This production takes 10 stages. Its shape allows two different materials to be combined in a single process cycle. The main advantages of this production method are as follows: • A strong and permanent connection is ensured between the mask components, eliminating the need for assembly. It disappears. 15 • Leakproofness and durability are increased, and product integrity is preserved. • The production process becomes faster, more efficient, and more suitable for automation. • Patient comfort is maximized with the soft TPE area that comes into contact with the skin. This dual-material, PVC-free, dual-color oxygen 20 is produced using the overmolding method. masks are products manufactured using traditional methods, both functionally and in terms of production. It is a more advanced solution compared to others.
