Description

TARIFNAME ANTIBAKTERIYEL NANO MALZEME TEKNIK ALAN Bulus, medikal alanda kullanilacak olan nazogastrik tüp (NGT) basta olmak üzere enjektör gibi saglik aparatlarina ve ürünlerine kisacasi antibakteryel/antifungal etki istenen alanlarda uygulanacak olan kimyasal bir formülasyon kaplamasi ile ilgilidir. TEKNIGIN BILINEN DURUMU Enteral beslenme (EB) agizdan baslayarak jejunuma kadar sistemin degisik bölgelerine; dogrudan, bir tüp ile, perkütan girisimlerle veya cerrahi yöntemle uygulanabilir. Enteral beslenme gastrointestinal (GI) sistemi fonksiyonel olan hastalarda makro ve mikro besin maddelerinin nazogastrik veya nazoenterik, gastrostomi veya jejunostomi yoluyla devamli ya da aralikli olarak hastaya verilmesidir. Dört-alti hafta gibi kisa süreli beslenmede nazogastrik tüp (NGT) ve nazoenterik tüp (NET) en sik kullanilan araçlar iken, uzun süreli beslenme için gastrostomi veya jejunostomi açilmaktadir. Nazogastrik tüp (NGT) her yil hastaneye yatan yüz binlerce hastaya tibbi ve cerrahi uygulamalari tamamlayici olarak tanisal, koruyucu veya tedavi edici amaçlarla uygulanmaktadir. Nazogastrik tüp (NGT) uygulamasi plastik bir kateterin burun deliginden sokulup yutak ve özefagustan geçirilerek mide içerisine yerlestirme islemidir. Nazogastrik tüp uygulamasi siklikla enteral beslenme ve beraberinde ilaç uygulama, mide dekompresyonu için kullanilan ve saglik profesyonellerinin sorumlulugunda olan invaziv bir uygulamadir. Ayrica midenin irrigasyonu ve tani Günümüzde NGT'ler Polipropilen, polyvinylchloride. lateks, silikon veya poliüretan gibi materyallerden yapilmistir. Polyvinylchlorid'ten üretilen tüpler genellikle yedi günden daha az sürecek kisa süreli beslenmeler için uygundur. Poliüretan tüpler özellikle enteral beslenme için daha uygundur. Bu tüpler nonreaktif bir madde olan, yumusak ve esnek kalabilen poliüretandan üretilmistir. Tüpler uzun periyodlarda kullanildiginda hastalarda özofageal ve gastrik erozyonlara sebep olabilirler. Polivinil klorid tüplerin her üç-bes günde bir, silikon veya poliüretan tüplerin sekiz haftadan sonra degistirilmeleri gerekir. Mortalite oranini gibi mikroorganizmalar NGT'de mikrobiyal kolonizasyon ve kontaminasyona yol açmakta ve bu mikroorganizmalar NGT'yi rezervuar olarak kullanmaktadir. NGT'nin mikroorganizma ile kontaminasyonu abdominal distansiyon, bakteriyemi, diyare, pnömoni gibi birçok komplikasyonun gelismesine ve hatta ölüme yol açmaktadir. Yapilan çalismalarda, NGT yerlestirildikten 15 dakika sonra bakteriyel kontaminasyonun gelistigi; 24 saat sonunda tüplerin %60'inda, 48 saat sonunda ise tamaminda biofilm olustugu ve NGT'nin dis yüzeyinde kontaminasyona neden olan mikroorganizmalarin ayni zamanda tüpün iç kisminda da yer aldigi belirlenmistir. Nano gümüs partiküller etkili ve genis spektrumlu antibakteriyel aktiviteleri sebebi ile istenmeyen mikroorganizmalari ortadan kaldirmak ve kontaminasyonu önlemek amaciyla kullanildigi bilinmektedir. Bakteri ve virüsler bile nano gümüs parçaciklarinin yaninda dev yapilar olarak kalmaktadir ve nano boyuttaki (0-200 nm) gümüs parçaciklarina temas eder etmez hücresel yapilari bozularak ölmektedirler. Nano gümüs, antibakteriyel tesiri ve bakterilerin antibiyotiklere karsi gelistirdigi direnci gümüse karsi gelistirememeleri dolayisi ile uzun yillardir bilim çevresinin dikkatini çekmeye devam etmektedir. Nano boyutlarindan dolayi, gümüs parçaciklar herhangi bir maddenin yüzeyinde kapli oldugunda, yüzey alani birkaç milyon kat artarak, çok güçlü anti bakteriyel etki saglar. Yukarida bahsettigimiz sekilde, enteral besinler üreme için ideal ortamlardir ve kontaminasyon olustugunda bakteriler hizla çogalirlar ve gastrointestinal yolun kontaminasyonu diyareye yol açabilir. Enteral beslenen hastalarda bakteriyal kontaminasyonun önlenmesine yönelik olarak el hijyenine uyulmasi, formül kutusu açma kapaginin alkollü bezle silinmesi, yatak basi formül set ve torbasinin her 24 saatte bir rutin olarak degistirilmesi, besin formüllerinin her dört saatte bir yeniden hazirlanmasi, açik formüllerin buzdolabinda saklanmasi önerilmektedir. Ancak bunlarin hepsi teknikteki problemlerin çözümünde yetersiz kalmaktadir. borusunun iç duvarini buna karsi sizdirmaz bir sekilde çekmek için en az bir emme portu içeren en az bir vakum Iümeni içeren bir nazogastrik tüp, söz konusu en az bir emme portu, doku hasarini önemli ölçüde önleyen benzersiz bir içbükey yapiya sahiptir." Seklinde özetlenmistir. Mevcut basvuru NGT lerin Küçük komplikasyonlar arasinda burun kanamasi, sinüzit ve bogaz agrisi bulunur. Bazen, tüpün sabitlendigi burunda asinma, özofagus perforasyonu, pulmoner aspirasyon, çökmüs bir akciger veya tüpün intrakraniyal yerlesimi gibi daha önemli komplikasyonlar ortaya çikmasi teknik problemi üzerine gitmis ve bunun için Uygulanan emme kuvveti nedeniyle doku hasarina neden olmadan bir yemek borusunun iç duvarini kendine dogru çekebilen emme portlarina sahip gelistirilmis NGT'lere ihtiyaç oldugu iddasindadir. Dolayisiyla mevcut teknik problemimizden ve sundugumuz çözümden uzaktir. tüpü boslugu dahil olmak üzere çift tüp bosluguna sahip bir nazogastrik tüpü açiklar, tüp gövdesinde kilavuz teli yönlendirmek için bir kilavuz tel tüp boslugu saglanir, kilavuz tel tüp boslugu ucu çikmaz uçtur, kilavuz telin çapi boru boslugu, kilavuz telinkine esdegerdir. Nazogastrik tüpün avantajlari sunlardir: 1 kilavuz tel ve eksüdalarin in vivo olarak dogrudan temasi sorununu etkin bir sekilde çözerek enfeksiyon kontaminasyonu olasiligini azaltir; 2, nazogastrik tüpün çapini kilavuz telinkine esdeger ayarlayarak tüpü vücuda düzgün bir sekilde yerlestirmek ve dogru bir sekilde konumlandirmak için nazogastrik tüp gövdesinin gücünü büyük ölçüde artirir, böylece islemi bir kez yerlestirme ile bitirir, tekrarlayan islemlerden kaçinir ve hastalarin agrisini azaltir .seklinde özetlenebilmektedir. Ancak mevcut basvuru da sunmus oldugumuz çözümden uzaktir. Sonuç olarak mevcut teknikte var olan ve günümüzde kullanilmakta olan yapilanmalara ve uygulamalara ait eksikliklerin ve dezavantajlarin ortadan kaldirilmasina olan gereksinim, ilgili teknik alanda bir gelistirme yapmayi zorunlu kilmaktadir.

Islevi esnasinda nano gümüs herhangi bir sekilde reaksiyona girmemekte, sekli bozulmamakta ve islevindeki süreklilik devam etmektedir. Bu sayede canlilar zarar görmeden NGT'lerin temas ettigi yüzeylerde antibakteriyel etki saglanmis olacak dolayisiyla da hasta tedavisi sirasinda çesitli bakterilerin varligi sebebiyle olusabilecek negatif etkiler ortadan kaldirilmis olacaktir. Bulusun bir diger amaci, Nazogastrik tüp üzerine yapilacak olan antibakteriyel örtünün hem bakteri hem de mantarlar gibi farkli mikroorganizmalar üzerinde güçlü aktivite göstermesinin beklenmesidir. Ayni zamanda kokusuz, lekesiz, kullanici üzerinde toksik etkisi olmayan ve yikanabilir bir kumas olmasi da ürünün getirecegi yeniliklerdendir. Bu çalisma ile nanokaplama teknolojisinin en önemli uygulamalarindan olan "Sol Jel Kaplama" teknikleri kullanilarak, "antibakteryel kaplamalar" elde edilecektir. Bu bulus sayesinde hali hazirda kullanilan NGT'ler hasta tedavisi sürecinde antibakteriyel etki saglayacaktir. Bu sayede Nazogastrik Tüplerin temas ettigi yüzeylerde antibakteriyel etki saglanmis olacak dolayisiyla da hasta tedavisi sirasinda çesitli bakterilerin varligi sebebiyle olusabilecek negatif etkiler ortadan kaldirilmis olacaktir. BULUSUN DETAYLI AÇIKLANMASI Bu detayli açiklamada bulus konusu yapilanmasinin tercih edilen alternatifleri, sadece konunun daha iyi anlasilmasina yönelik olarak ve hiç bir sinirlayici etki olusturmayacak sekilde açiklanmaktadir.

TR TR TR DESCRIPTION ANTIBACTERIAL NANO MATERIAL TECHNICAL FIELD The invention is related to a chemical formulation coating to be applied to healthcare apparatus and products such as syringes, especially nasogastric tube (NGT) to be used in the medical field, in short, in areas where antibacterial/antifungal effect is desired. KNOWN STATE OF THE TECHNIQUE Enteral nutrition (EB) is applied to different parts of the system, starting from the mouth to the jejunum; It can be applied directly, through a tube, percutaneous interventions or surgically. Enteral nutrition is the continuous or intermittent administration of macro and micronutrients to patients with a functional gastrointestinal (GI) system via nasogastric or nasoenteric, gastrostomy or jejunostomy. While nasogastric tube (NGT) and nasoenteric tube (NET) are the most commonly used tools for short-term feeding such as four to six weeks, gastrostomy or jejunostomy is opened for long-term feeding. Nasogastric tube (NGT) is applied to hundreds of thousands of hospitalized patients every year for diagnostic, preventive or therapeutic purposes as a complement to medical and surgical procedures. Nasogastric tube (NGT) application is the process of inserting a plastic catheter through the nostril, passing it through the pharynx and esophagus and placing it into the stomach. Nasogastric tube application is an invasive procedure that is frequently used for enteral nutrition, drug administration, and gastric decompression and is the responsibility of healthcare professionals. Also, irrigation of the stomach and diagnosis. Today, NGTs are Polypropylene, polyvinylchloride. It is made of materials such as latex, silicone or polyurethane. Tubes made of polyvinylchloride are suitable for short-term feedings, usually lasting less than seven days. Polyurethane tubes are especially suitable for enteral nutrition. These tubes are made of polyurethane, which is a non-reactive material and remains soft and flexible. When tubes are used for long periods, they may cause esophageal and gastric erosions in patients. Polyvinyl chloride tubes should be replaced every three to five days, and silicone or polyurethane tubes should be replaced after eight weeks. Microorganisms such as mortality rate cause microbial colonization and contamination in NGT, and these microorganisms use NGT as a reservoir. Contamination of NGT with microorganisms leads to the development of many complications such as abdominal distension, bacteremia, diarrhea, pneumonia, and even death. Studies have shown that bacterial contamination develops 15 minutes after NGT is placed; It was determined that biofilm was formed in 60% of the tubes after 24 hours and in all of them after 48 hours, and the microorganisms that caused contamination on the outer surface of the NGT were also found in the inner part of the tube. It is known that nano silver particles are used to eliminate unwanted microorganisms and prevent contamination due to their effective and broad-spectrum antibacterial activities. Even bacteria and viruses remain giant structures next to nano silver particles, and as soon as they come into contact with nano-sized (0-200 nm) silver particles, their cellular structures deteriorate and they die. Nano silver has continued to attract the attention of the scientific community for many years due to its antibacterial effect and the fact that bacteria cannot develop the resistance to silver that they have developed against antibiotics. Due to their nano size, when silver particles are covered on the surface of any substance, the surface area increases several million times, providing a very strong antibacterial effect. As we mentioned above, enteral foods are ideal environments for reproduction, and when contamination occurs, bacteria multiply rapidly and contamination of the gastrointestinal tract can lead to diarrhea. To prevent bacterial contamination in enterally fed patients, it is recommended to comply with hand hygiene, wipe the formula box opening cover with an alcohol swab, routinely change the bedside formula set and bag every 24 hours, re-prepare nutritional formulas every four hours, and keep open formulas in the refrigerator. However, all of these are insufficient to solve technical problems. "A nasogastric tube comprising at least one vacuum lumen including at least one suction port for sealing the inner wall of the tube, said at least one suction port having a unique concave structure that substantially prevents tissue damage." Minor complications of NGTs include nosebleeds, sinusitis, and sore throat. Sometimes, more serious complications such as abrasion in the nose where the tube is fixed, esophageal perforation, pulmonary aspiration, a collapsed lung, or intracranial placement of the tube arise. It claims that there is a need for improved NGTs with suction ports that can pull the inner wall of an esophagus towards itself without causing tissue damage due to its force. Therefore, the current technique is far from our problem and the solution we present describes a nasogastric tube with a double tube space, including the tube space, in the tube body A guide wire tube gap is provided to guide the guide wire, the guide wire tube gap end is a dead end, the diameter of the guide wire pipe gap is equivalent to that of the guide wire. The advantages of the nasogastric tube are as follows: 1 it effectively solves the problem of direct contact of the guide wire and exudates in vivo, reducing the possibility of infection contamination; 2, it can be summarized as follows: By adjusting the diameter of the nasogastric tube equivalent to that of the guide wire, it greatly increases the strength of the nasogastric tube body to properly insert the tube into the body and position it accurately, thus finishing the process with one time insertion, avoiding repetitive operations and reducing patients' pain. However, the current application is far from the solution we have presented. As a result, the need to eliminate the deficiencies and disadvantages of the structures and applications that exist in the current technique and are used today necessitates a development in the relevant technical field. DESCRIPTION OF THE INVENTION The present invention is an antibacterial nano material coated coating developed to eliminate the disadvantages mentioned above and bring new advantages to the relevant technical field. The purpose of the invention is to provide an effective solution that will show antibacterial/antifungal activity against pathogens on the NGT surface with the coating developed with a composition containing antibacterial/antifungal nano silver ions. . Nano silver used in the invention does not harm human health, pets, plants, in other words, multicellular creatures. During its function, nano silver does not react in any way, its shape does not deteriorate and the continuity of its function continues. In this way, an antibacterial effect will be provided on the surfaces contacted by NGTs without harming living things, and therefore the negative effects that may occur due to the presence of various bacteria during patient treatment will be eliminated. Another purpose of the invention is that the antibacterial cover to be applied on the Nasogastric tube is expected to show strong activity on different microorganisms such as both bacteria and fungi. At the same time, being an odorless, stain-free, non-toxic and washable fabric is among the innovations that the product will bring. With this study, "antibacterial coatings" will be obtained by using "Sol Gel Coating" techniques, which is one of the most important applications of nanocoating technology. Thanks to this invention, currently used NGTs will provide an antibacterial effect during the patient treatment process. In this way, an antibacterial effect will be provided on the surfaces in contact with the Nasogastric Tubes, thus the negative effects that may occur due to the presence of various bacteria during patient treatment will be eliminated. DETAILED DESCRIPTION OF THE INVENTION In this detailed explanation, the preferred alternatives of structuring the subject of the invention are explained only for a better understanding of the subject and in a way that does not create any limiting effect. The nano solution, for which antibacterial activity tests have been carried out in accordance with the standards, will be coated directly on the nasogastric tubes with spraying, dipping, and brush application techniques and dried. For industrial applications, mass production can be carried out in a production line with the spraying method, followed by an effective drying phase, so that the nasogastric tubes are coated homogeneously. Sodium borohydride is used for antibacterial nanomaterial-coated NGTs. This compound is produced from the boron mineral and one of the most important purposes of its use in this invention is that it is a strong reductant. Sodium borohydride can store hydrogen in structures by weight and can also store them easily. Then Polyvinylpyrrolidone (PVP) is added to this composition. Nanoparticles prepared using this will be distributed homogeneously in the solution. There will be nanosilver particles in equal concentrations everywhere. PVP addition is made between 0.5-4.0% by weight. Oleic acid is also added to the composition at the rate of 0.5-2.0% by weight. With this addition, moisture is provided on the surface of the nano silver solution. In addition, nano-solution is prepared by adding 30-35% by weight of silver nitrate, the material that will be reduced to nano size for antibacterial activity, as the most important main compound. The nano-sized solution, which is mixed extremely homogeneously with a mechanical stirrer for 24 hours, is applied to the NGTs by spraying, dipping, brush application methods and allowed to dry. (Track 1 and 2). The reason for using deionized water in the invention is that it is completely free of all organic, inorganic components and minerals. In addition, since deionized water has no taste, smell, color or conductivity, it has no effect on the chemicals or solutions it comes into contact with. Chemicals Percentage Sodium Borhydride 0.5-4% OIleic Acid 0.5-2% Silver Nitrate 30-35% Deionized Water 14-39% Total 100 The invention is a formulation applied to an antibacterial nano material coated nasogastric tube to be used in the medical field; The entire formula contains Silver Nitrate and 14-39% Deionized Water by weight. The production method of the invention; - Dissolving all of the chemicals separately in deionized water, - Adding PVP (Polyvinylpyrrolidone) into Sodium Boron Hydride, - Adding oleic acid to the resulting chemical mixture, - Then adding silver nitrate to the resulting mixture, - Preferably mixing the resulting mixture homogeneously with 24 mL. Mixing with a mechanical mixer for an hour, - Applying the resulting nano-sized solution directly on the apparatus to be applied by spraying, dipping or brush application methods, or preferably on a nonwoven fabric, in the same way by one of the same dipping, spraying or brush application methods, - The applied process includes the steps of drying, preferably in an oven at 75-100 degrees. Among the temperature values used in the invention, the maximum efficiency is 85 degrees, but 75-100 degrees can also be preferred. The nonwoven fabric used is hydrophobic and has the ability to repel existing water. PVP and Sodium BoronHydride used in the invention were used as reducing agents. While Silver Nitrate provides antibacterial properties, Oleic acid also acts as a stabilizer in the present invention. TR TR TR
