Description

人工血管注射模擬器Artificial blood vessel injection simulator

本創作係有關醫療注射輔具的技術領域,尤指一種人工血管注射模擬器。This creation is related to the technical field of medical injection aids, especially an artificial blood vessel injection simulator.

人工血管結構分為注射座和導管二部分,注射座大小如 10 元硬幣圓盤,中間有矽質的橡皮;圓盤旁有一條導管,長約 20 公分植入血管內,為安全性高之給藥途徑。應用時,由醫生簡單小手術安裝,完全埋入病患皮下,不會影響日常的生活,部位可供重覆打針注射,被廣泛應用來幫助需要長期接受化學治療的病人,以免除每次打針還要尋找周邊血管的煩惱,同時又可避免化學藥物滲漏及降低血管變硬與反覆扎針的痛苦。The artificial blood vessel structure is divided into two parts: an injection seat and a catheter. The injection seat is as large as a 10 yuan coin disc with a silicon rubber in the middle. There is a catheter next to the disc, which is about 20 cm long and implanted in the blood vessel, which is highly safe. Route of administration. In application, it is installed by a doctor with a simple minor operation and is completely buried under the patient's skin. It will not affect the daily life. The site can be used for repeated injections. It is widely used to help patients who need long-term chemotherapy to avoid each injection. It is also necessary to look for the troubles of peripheral blood vessels, while avoiding chemical leakage and reducing the pain of blood vessel hardening and repeated needle sticking.

人工血管是一項重要又有效的醫療方式,必須使用專屬針頭,稱為蝴蝶彎針。住院期間可連續使用,但每 7 天需更換一次蝴蝶彎針。人工血管用畢若暫時不需再用,還得以稀釋之抗凝劑沖洗後再拔出彎針,以防管路阻塞…等,諸多相關護理照護及注意事項。因此,相關醫護人員都必須經過一定的養成訓練,始能熟悉技術面對病患提供最佳的醫療服務。Artificial blood vessel is an important and effective medical method, and special needles, called butterfly curved needles, must be used. It can be used continuously during the hospitalization, but the butterfly looper needs to be changed every 7 days. After the artificial blood vessel has been used, it needs to be reused temporarily. It can be washed with the diluted anticoagulant before pulling out the curved needle to prevent the tube from obstructing... etc., many related care and precautions. Therefore, relevant medical staff must undergo a certain degree of training before they can be familiar with technology to provide the best medical services to patients.

一般習知的人工血管教學用模具,主要係在含胸半臂的人體模型內配置安裝一人工血管及其對應的管路充填容間,以供醫療教學模擬人工血管注射及清洗練習使用,但其模具組成造價高約數十萬,體積大笨重佔空間,耗材成本高練習用皮費用不斐,而且又需回廠更換往返時間長。一般教學上學員必須分批練習,無法每個學員人手一個隨身攜帶反覆訓練,技術養成不容易純熟快速學會,為其主要缺點。Commonly known artificial blood vessel teaching molds are mainly configured to install an artificial blood vessel and its corresponding pipeline filling chamber in a human body model with a thoracic arm, for medical teaching simulation artificial blood vessel injection and cleaning exercises, but its The cost of the mold composition is about hundreds of thousands, the volume is bulky and takes up space, the cost of consumables is high, the cost of training leather is high, and it takes a long time to return to the factory for replacement. In general, students must practice in batches. It is not possible for each student to carry one person for repeated training. It is not easy to develop skills and learn quickly, which is its main disadvantage.

而且習知人工血管教學用模具,因為內部結構配置尚欠完善,設計功能受限只能用來模擬一般正常的人工血管注射練習,根本無法用來模擬跑針異位注射液滲漏造成注射部位腫脹醫療突發的緊急處理訓練,為其另一缺點。Moreover, the conventional artificial blood vessel teaching mold, because the internal structure configuration is not perfect, the design function is limited, it can only be used to simulate normal artificial blood vessel injection exercises, and it cannot be used to simulate the injection site caused by the leakage of the ectopic injection of the needle. Emergency treatment training for swelling medical emergencies is another disadvantage.
