M353021 八、新型說明： 【發明所屬之技術領域】 本發明係關於一種兩截式鼻胃管之結構設計，特別是 -關於一種可定位於人體鼻前庭内，藉由鼻胃管裝置分設成第一 :管體及第二管體，再透過第一管體設有一固定部將鼻胃管定位 、於鼻前庭位置，再藉由第二管體一端之連接部與固定部結合而 形成本發明之結構設計。 •【先前技術】 鼻胃管為一種醫療器材結構，為用來導入或移除流質至病 患體内外，主要功能如餵食、引流、治療等醫療行為，其使用 '時機為經常用於因病患中風或昏迷等狀況，而無法進食或容易 嗆到引起吸入性肺炎時，可以使用鼻胃管餵食液體狀食品，或 是因上消化道出血、腸阻塞、腸胃道手術後，可藉由鼻胃管排 除胃裡多餘的物體，如血或空氣，避免因嘔吐嗆到或是排除腹 _脹之不舒適感，亦有當醫生懷疑病患可能有上消化出血之情況 t時，例如有吐血或解黑便之病徵時，經常放置鼻胃管沖洗或是 診斷出血情況，來進一步研判是否需要緊急安排胃鏡或其他治 療。然而鼻胃管為一種外接置入性人體之裝置，對於病患最為 不舒服的階段為放置的過程中，經常觸碰到咽喉，依每個人的 敏感度不同，可能會有想嘔吐或是疼痛的感覺，甚而有時會使 用局部麻醉的潤滑軟膏，來減輕病患的不舒服感。 5 M353021 使用鼻胃管結構診療留置體内的時間，會因個人病況而 異，短則三到七天，若是因進食情況欠佳，影響營養狀況而使 用鼻胃管之情況下，則可能留置鼻胃管更長的時間，然由於鼻 -胃管為一長條軟管結構，故當病患因醫療行為而必須裝設鼻胃 :管時，該鼻胃管必然於穿插過程中通過人體之鼻腔、喉部進而 t進入到食道各器官，經由食道連接人體内部之消化系統，過程 極度不舒服；而該鼻胃管另一端於人體外部一端則設有一流質 籲導入或移除之接設部結構，而現今通常鼻胃管於裝置後之定位 方式，為繞置於病患之鼻頭、臉頰、衣領等位置上定位；然而 前述之鼻胃管於穿置後，留置身體時間長短不定，間接影響病 患之通常生活，經常產生下述狀況： 一、 由於病患於穿置鼻胃管後，無法在使用前間取出鼻胃 管，然當病患外出活動或暫出醫療場所時，必須纏繞鼻胃管於 身上，因此造成病患外觀上的不雅，且易於被他人以異樣的眼 籲光看待，此種狀況對於身心狀態較為不健康的人容易造成身心 負面的壓力。 hi 二、 病患於穿置鼻胃管後翻身活動時，導致到會有不小心拉 扯造成管路脫落，或因使用鎮靜劑或麻醉藥品時，可能出現下 意識的拉扯拔除的動作。 三、 然重新穿置鼻胃管，病患必須再一次經歷極為不舒服之 醫療過程，甚而護理人員為了避免病患反抗動作發生，必要時 6 M353021 可能會執行保護約束，將病患束缚，造成病患身心各方面之壓 力與排斥，對於已處於病痛狀態的病人產生更不良的影響。 請參閱圖一所示之習知鼻胃管結構50，該鼻胃管結構50 、為自鼻前庭(Vestibule)内穿設至食道内至人體胃部等器官位 :置，而鼻胃管結構50 —端為侵入人體内之插入端51，另一端 則為預留於人體外部之接設部52，該接設部52結構主要為供 連結灌食器等物品注入流質灌食，或連接抽取裝置做抽出體内 _物質之作用，故該鼻胃管50可選用與人體相合度高之熱塑性 塑膠材質，例如聚乙稀（Polyethylene，PE)、聚丙浠 (Polypropylene，PP)、聚氯乙浠(Polyvinylchloride, PVC)等材 質，製作成一具有光滑平面之管體；然由第一圖顯可得知由於 鼻胃管50之軟質塑膠材質可能因形狀容易受外力擠壓扭曲， 故鼻胃管的管徑必須兼顧安全及強度及抗體内酸度的情況，因 此必然有一定的管徑寬度，也因管徑必須有一定的要求，故必 ®然於穿設醫療過程中，另病患感到痛苦難耐。 【發明内容】 本發明人有感於病患接受鼻胃管治療時所承受之痛苦與 心理層面的壓力，為求改善鼻胃管治療的醫療品質，並兼顧病 患之身心健康，因此研發出本發明之兩截式鼻胃管結構，藉以 改善醫療腸胃消化系統經常使用之鼻胃管結構，不但可有效將 鼻胃管定位於鼻前庭内，且透過可分離之結構設計使病患可免 7 M353021 除重複插拔鼻胃管的身體痛苦，並可減輕病患因外觀改變所承 受之心理壓力。 請參閱圖二所示之侧面剖視實施例圖所示，本發明兩截式 鼻胃管結構係分設成第一管體10及第二管體20，其特點為第 —管體10於鼻前庭(Vestibule)内，設有一與鼻前庭外型相似之 固定部11 ’藉由鼻前庭(Vestibule)較鼻腔(Nasal cavity)前之鼻 閾（Limen nasi)開口有更大面積之特性，使該固定部η可留置 於鼻前庭(Vestibule)内，其固定部11 一端外緣形狀構造設計係 配合鼻前庭(Vestibule)内部形狀，進而與鼻前庭(Vestibule)内腔 表面表皮抵靠’而不會向内滑移移動到相對於鼻前庭(Vestibule) 表面積較小之人體氣管内部；而第二管體20相對於第一管體 10固定部11之一端則設有一連接部21，該連接部21可連接 或分離於固定部11上，使第二管體20可隨時的接設於第一管 體10上而形成完整的鼻胃管結構，或分離取下而避免患者行 動時還必須纏繞不可分離的鼻胃管，導致產生前述習用鼻胃管 諸多對患者產生的不便。 以下將配合圖式進一步說明本發明的實施方式，下述所列 舉的實施例係用以闡明本發明之結構特徵，但並非用以限定本 發明之範圍，任何熟習此技藝者，在不脫離本發明之精神和技 術應用範圍内，當可做些許更動與潤飾，因此本發明之權利請 求範圍，當視後附之申請專利範圍所界定者為準。 M353021 【實施方式】 請視圖三及圖四所示之本發明兩截式鼻胃管結構較佳實 施例設計，本發明設有一可供侵入人體内部之第一管體及 -一連結第一管體10之第二管體20,其中第一管體10之一端設 :有一固定部11與第一管體10連接’該固定部11 一端開設有 .一套設端111之桿狀體，其可以為透過超音波融合或黏合等方 式使固定部11與第一管體10之軟管12連結成一體，該固定 •部11之結構特徵為其為穿入人體後置於鼻前庭(Vestibule)内空 間中，且面積大於較前述之鼻閾（Limen nasi)之開口面積大，透 過該鼻閾（Limen nasi)表皮内部為硬骨構造’故不會有擴張的可 '能，使得固定部11抵頂於鼻前庭(Vestibule)内空間後，可安全 的限制於抵頂於鼻閾（Limen nasi)外，且特別明該鼻前庭 (Vestibule)之表皮組織與體外皮膚組織相同，故可如皮膚組織 一般可接觸物體表面而不會有所感染或產生傷害的狀況，因此 —固定部11裝設於鼻前庭(Vestibule)内空間後不會產生對其表皮 _組織有所影響’而第一管體10相對於固定部11之另一端則按 傳統插管之方式侵入人體體内，而該固定部11上之一處設計 有一通氣孔丨丨2供固定部11置入鼻前庭(Vestibule)後提供鼻腔 内更多的通氣管道，而固定部11相對於與套設端111之另一 端則開設有一接合端I13，在本較佳實施例中，該接合端113 為螺桿之設計，使其供第二管體20與其螺接，另固定部11更 9 M353021 可於罪近接合端113之—側緣凸設有_勾狀之定位體n4，使 該定位體114於固定部11置入鼻前庭(Ves_le)後藉其勾狀形 體勾持於鼻部外圍，增加敎性，蚊部11中心更設有一内 ^ 導通於套▲端111與接合端113 P3 ;而連接於第一管 體s之固定7 11外之第二管體20 一端’其設有一連接部21， 其中該第—g體2G為連接固定部U露出於人體鼻腔外部，另 ^同樣<有與習用鼻胃f 5G相同之接設部（圖未示），其中 該連接部21於本實施例中之設計，為設有—與前述之接合端 …相螺接之螺巾w結構，供螺鎖於接合端113上，此部之設計 為提供使用者可快速接合第二管體Μ於第—管體⑺之設計， “方式車乂為穩定、安全，主要是提供意識正常且不會排 斥之病。使用’錢接部21再連設-桿體23後，與第二管體 20之軟管24接設而形成-體。 再w參閱®五及圖六所示之另—較佳實施例所示之 設計’該岐部11與連接部21之結構設計更可為固定部^ 相對於連接^ 21之—端為以筒體構造之套合端116設計為連 接之《又片其中該套合端ΐΐ6之開口端外凸有一凸緣，而第二 &體20套接别述套合端116位置設有―套接端，其中該套 接端22内^叹有—嵌入套合端116内之接桿222,而其外圍設 有Ρ :邊221之形體，透過該叩合邊221内緣設有與固定部u 之套合端116之凸緣形體相扣合之凸緣構造，使叩合邊221與 M353021 套合端116接合時，透過兩凸緣相叩合後定位，此一另一實施 * 例固定部11與連接部21之叩合結構設，主要在於提供實施鼻 胃管穿置之病患若有精神不能自主導致拔管或活動能力不良 -導致經常卡勾到鼻胃管之狀況所設計，該叩合邊221與套合端 :116接合後，僅具有一定之固持力，超過預設之固持力之瞬間 -力道會導致脫離，使穿置後之鼻胃管之第一管體10仍能留置 於體内，不需再從新穿置，而如欲抽離第一嘗體10，仍可自鼻 •腔中取出第-管體10。 綜上所述，本發明之兩截式鼻胃管’透過第一官體及第二 管體，以及其固定部及連接部之設計’提供病患於使用本發明 .結構時，可依實際狀況分離第二管體，俾便外出且較具美觀’ 且避免重複穿置鼻胃管之不適感，增加病患之自^〜等功效， 且本發明結構設計並無近似之專利申請在先’實已符口專利法 中之可專利要件，爰依法提出發明專利申請。 •【圖式簡單說明】 ，第一圖：係習用結構之使用示意圖。 第二圖··係本發明之侧面剖視組裝示意圖。 第三圖：係本發明之部分結構分解示意圖。 第四圖：係本發明之部分結構分解剖視示意圖。 第五圖：係本發明之另-實施例部分結構刻視組裝不意圖。 第六圖：係本發明之另-實施例側面剖視組裝示意圖。 M353021 【主要元件符號說明】 10·••第一管體 11…固定部 111…套設端 112···通氣孔 -113···接合端 114···定位體 :115···内管徑 116···套合端 -12···軟管 '20…第二管體 21…連接部 _22…套接端221…叩合邊 222…接桿23…桿體 24…軟管 12M353021 VIII. New type of description: [Technical field to which the invention pertains] The present invention relates to a structural design of a two-section nasogastric tube, in particular to a type that can be positioned in a human nasal vestibule, which is divided into a nasogastric tube device. First, the tube body and the second tube body are further provided with a fixing portion through the first tube body to position the nasogastric tube at the nasal vestibule position, and then the base portion of the second tube body is combined with the fixing portion to form the present portion. The structural design of the invention. • [Prior Art] The nasogastric tube is a medical device structure used to introduce or remove fluid to the inside and outside of the patient, and its main functions such as feeding, drainage, treatment and other medical activities, the use of 'time is often used for disease If you have a stroke or coma and cannot eat or are prone to cause aspiration pneumonia, you can use the nasogastric tube to feed liquid food, or because of upper gastrointestinal bleeding, intestinal obstruction, and gastrointestinal surgery, you can use the nose. The stomach tube excludes excess objects in the stomach, such as blood or air, to avoid vomiting or to exclude the abdomen _ bloating discomfort, and when the doctor suspects that the patient may have upper digestive bleeding, such as vomiting blood Or when the symptoms of melena are removed, the nasogastric tube is often flushed or the bleeding is diagnosed to further determine whether emergency gastroscopy or other treatment is needed. However, the nasogastric tube is a device for externally implanted human body. The most uncomfortable stage for the patient is to touch the throat during the placement process. Depending on the sensitivity of each person, there may be vomiting or pain. The feeling is that sometimes a local anesthetic lubricating ointment is used to alleviate the patient's discomfort. 5 M353021 The time of indwelling in the use of nasogastric tube structure will vary from individual to individual, ranging from three to seven days. If the feeding condition is poor and the nutrient condition is affected and the nasogastric tube is used, the nose may be placed. The stomach tube is longer, but because the nose-stomach tube is a long hose structure, when the patient has to install a nasogastric stomach due to medical behavior: when the tube is in use, the nasogastric tube must pass through the human body during the insertion process. The nasal cavity, the throat and then t enter the organs of the esophagus, connecting the digestive system inside the human body via the esophagus, the process is extremely uncomfortable; and the other end of the nasogastric tube is provided with a first-class quality appeal or introduction. Department structure, and nowadays usually the positioning of the nasogastric tube after the device is positioned around the nose, cheeks, collar, etc. of the patient; however, the aforementioned nasogastric tube is indwelled for a long time after being placed. Indirectly affecting the normal life of patients, often the following conditions occur: First, because the patient can not take the nasogastric tube before use after wearing the nasogastric tube, when the patient goes out for activities or temporarily takes out medical treatment The time must be nasogastric tube is wound on the body, thus causing patients indecent appearance, and easy to be called on others in strange light eyes look, this situation is more unhealthy for the physical and mental state of the person is likely to cause negative physical and psychological pressure. Hi 2. When the patient turns over after wearing the nasogastric tube, it may lead to accidental pulling and causing the tube to fall off, or when using sedatives or narcotic drugs, there may be a subconscious pulling action. Third, when the nasogastric tube is re-applied, the patient must once again experience a medical process that is extremely uncomfortable. Even if the nursing staff avoids the patient's resistance, the 6 M353021 may perform protection constraints and bind the patient. The stress and rejection of all aspects of the body and mind of the patient have a more adverse impact on patients who are already in a state of illness. Please refer to the conventional nasogastric tube structure 50 shown in Fig. 1. The nasogastric tube structure 50 is arranged from the inner vestibule (Vestibule) to the esophagus to the stomach of the human body, and the nasogastric tube structure.
