較佳實施例之詳細說明 現請詳細參閱本發明的實施例,該各例係被示於所附 圖式中。儘可能地,相同的編號會被用來在各圖中標示相 同或類似的部件。 10 第2圖為一依本發明一實施例之眼科醫療裝置的平面 圖,其包含一可棄的尖端部段與一有限的再使用總成。在 第2圖中,該醫療裝置包含一尖端部段205及一有限的再使 用總成250。該尖端部段205包含一針210,一殼體210,及 一選擇燈275。該有限的再使用總成250包含一殼體255,一 15 開關270,一鎖定機構265,及〆螺紋部260。 尖端部段205能被連結於有限的再使用總成250,並由 之卸除。在本實施例中,尖端部段205具有一螺紋部設在該 殼體215的内表面上,其會螺合於該有限的再使用總成25〇 之螺紋部260。此外,鎖定機構265會將尖端部段215固定於 2〇有限的再使用總成250。該鎖定機構265可呈一按鈕,一滑 動開關’或一懸桿機構的形式。其它可用以將尖端部段205 連結於有限的再使用總成250之機構,譬如含有能夠互相配 、°構特徵者,已在該領域中普遍習知,且在本發明的 範圍内。 200826988 該針210係可適於將-物質,譬如藥劑,輸送至一眼睛 内、。該針210可為任何_般習知的構形。較好是,該針21〇 係被設計成令其熱特性對特定的藥劑輸送用途是有傳導性 的。例如,當一加熱的藥劑要被輸送時,該針21〇的長度可 5以相對較短(數毫米)來促進藥劑的妥善輸送。 開關270係可適於提供一輸入至該系統。例如,開關 可被用來作動該系統或啟動—加熱器。其它的開關、按紐, 或使用者導引的控制輸入等係已普遍習知,且可與該有限 的再使用總成250及/或尖端部段2〇5 一起被使用。 10 選擇燈275在該尖端部段205已備妥可供使用時將會照 壳。選擇燈275可由殼體215突出,或可被納裝於殼體215 内,在此情況下,選擇燈275可透過該殼體215之一透明部 份被看到。在其它實施例中,選擇燈275可被以一指示器取 代,譬如一液晶顯示器,片段顯示器,或其它能指示該尖 15端部段之狀態或情況的裝置。例如,選擇燈275亦可脈動地 開/關來表示其它的狀態,譬如但不限於一系統失誤,完全 充電的電池,充電不足的電池,或該尖端部段205與有限的 再使用總成250之間的不當連結。雖被示於設在尖端部段 205上,但選擇燈275或其它的指示器亦可被設在有限的再 2〇 使用總成250上。 第3圖為依本發明原理之有限的再使用總成之另一實 施例。該有限的再使用總成250包含一按紐308,一顯示器 320,及一殼體330。可棄的尖端部段205會附接於有限的再 使用總成250之末端340。按鈕308會作動來對該系統提供一 11 200826988 輸入。如同開關270,按鈕308係可啟動一加熱器或其它的 溫度控制裝置或促發一柱塞的作動。顯示器32〇為一液晶顯 示裔、片段顯示器,或能表示該可棄的尖端部段2〇5或有限 的再使用總成250之狀態或情況的其它裝置。 5 第4圖係為依本發明一實施例之可棄的尖端部段和有 限的再使用總成之截面圖。第4圖示出該尖端部段2〇5如何 與有限的再使用總成250配接。在第4圖的實施例中,尖端 部段205包含柱基介面420 ’柱塞415,施配腔室殼體425, 尖端部段殼體215 ’溫度控制裝置450,熱感測器460,針 10 210,施配腔室405,介面530,及端部介面連接器453。有 限的再使用總成250包含機械連桿組介面545,致動軸51〇, 致動器515,電源505,控制器305,有限的再使用總成殼體 535,及有限的再使用總成介面連接器553。 在尖端部段205中,柱塞介面420係位於柱塞415的一 15 端,柱塞415的另端會形成該施配腔室405的一端。柱塞415 係可在施配腔室405内滑動。柱塞415的外表面係流體地密 封於施配腔室殼體425的内表面。施配腔室殼體425會包圍 該施配腔室。通常,施配腔室殼體425具有一圓筒形狀。因 此,施配腔室405亦具有一圓筒形狀。 20 針210係流體地耦接於施配腔室。在此情況下,一容裝 於施配腔室405内的物質將能通過該針210再注入眼睛中。 溫度控制裝置450會至少部份地包圍施配腔室殼體425。在 此情況下,溫度控制裝置450係可加熱及/或冷却施配腔室 殼體425及任何容裝於施配腔室405内的物質。介面530會連 12 200826988 接溫度控制裝置450和端部介面連接器453。 可擇的熱感測器460會提供溫度資訊來協助控制該溫 度控制裝置450的操作。熱感測器460可被設在靠近施配腔 室殼體425處來測量該腔室425附近的溫度,或可被設成與 5 施配腔室殼體425熱接觸,於此情況下,其能測出施配腔室 殼體425的溫度。熱感測器460可為眾多能夠提供溫度資訊 的任何不同裝置。例如,熱感測器460可為一種熱耦,或一 種電阻裝置其電阻會隨溫度而改變。熱感測器亦電耦接於 介面530或其它類似的介面。 10 尖端部段205的部件,包括施配腔室殼體425,溫度控 制裝置450 ’及柱塞415等皆至少部份地被尖端部段殼體215 封圍。在一符合本發明之原理的實施例中,柱塞415係密封 於施配腔室殼體425的内表面。此密封可防止任何被容納於 施配腔室405中的物質受污染。就醫療目的而言,此等密封 15 是有需要的。此密封能被設在該柱塞415或施配腔室殼體 425上的任何點處。 在有限的再使用總成250中,電源505會提供電力給致 動器515。一在電源505與致動器515之間的介面(未示出)會 形成一導道可提供電力至該致動器515。致動器515係連接 2〇於致動軸510。當致動器515是為一步進馬達時,致動軸51〇 會與致動器515形成一體。機械連桿組介面545係連接於致 動軸510。在此構造中,若致動器515向上朝該針21〇移動致 動軸510,則機械連桿組介面545亦會朝該針21〇向上移動。 在本發明的其它實施例中,機械連桿組介面545與致動軸 13 200826988 510係為單一構件。換言之,一連接於致動器515的軸桿會 包含致動軸510和機構連桿組介面545而形成單一總成。 在有限的再使用總成250中,該電源5〇5典型係為一可 充電的電池’譬如一鐘離子電池,惟其它類型的電池亦可 5 被使用。此外,任何其它類型的電力單元亦可適用於作電 源505。電源505會提供電流至施配腔室殼體425來加熱它並 改變其形狀。可擇地,電源505能被經由一門或其它類似的 構件(未示出)來從該殼體255中移除。 控制器305係透過介面535連接於有限的再使用總成介 10面連接器553。有限的再使用總成介面連接器553係設在有 限的再使用總成殼體255之頂面上而鄰近於機械連桿組介 面545。以此方式,該有限的再使用總成介面連接器553和 機械連桿組介面545係可分別與端部介面連接器453和柱塞 介面420連接。 15 控制器305與致動器515係被一介面(未示出)連接。該介 面(未示出)可容控制器305控制致動器515的操作。此外,一 在電源505與控制器305之間的介面可容控制器3〇5控制電 源505的操作。於此情況下,若電源5〇5係為_可充電電池 則控制裔305可控制該電源5〇5的充電和放電。 Z〇 ㈣器3()5典型為一積體電路,乃具有電源、輸入和輸 出接腳而能夠執行邏輯功能。在不同的實施例中,控制器 305係為一定標的裝置控制器。於此情況下,控制器3〇5會 針對特疋的裝置或構件,譬如一溫度控制裝置或一電源 供應器來執行特定的控制功能。例如,一溫控裝置控制器 14 200826988 會具有控制-溫控農置的基本功能。在其它實施例中,控 制器3〇5係為一微處理器。於此情況下,該控制器305係可 程式化而使其能操作來控制該裝置中之一個以上的構件。 在/、匕h况下,控制器3〇5並非一可程式化的微處理器,而 5疋4寺殊目的的控制為被構製成可控制一些執行不同功能 的不同構件。雖在第5圖中係被示為一構件,但控制器 亦可由許多不同的構件或積體電路來製成。 尖端部段205係可配接或附接於有限的再使用總成 250。在第4圖的實施例中,位於柱塞415底面上的柱塞介面 10 420係可與靠近該有限的再使用總成殼體乃5頂面處的機械 連袢組介面545配接。此外,端部介面連接器453係可與有 限的再使用總成介面連接器553連接。當尖端部段2〇5被以 此方式連結於有限的再使用總成25〇時,致動器515和致動 軸510係可向上朝該針21〇驅動柱塞415。此外,一介面會形 15成於控制器305與溫度控制裝置450之間。一信號能從控制 器305經由介面535,有限的再使用總成介面控制器553,端 部介面控制器453,及介面530等傳送至溫度控制裝置45()。 在操作時,若尖端部段205係連接於有限的再使用總成 250,則控制器305會控制致動器515的操作。當致動器515 20被作動時,致動軸510會朝該針210向上移動。而與柱塞介 面420配接的機械連桿組介面54 5則會朝該針21 〇向上移動 柱塞415。一置於該施配腔室405内的物質將會經由該針21〇 被排出。 此外,控制器305會控制該溫度控制裝置450的操作。 15 200826988 溫度控制裝置450係可加熱及/或冷却施配腔室殼體425及 其内容物。因施配腔室殼體425係可至少部份地熱傳導,故 加熱或冷却施配腔室殼體425亦會加熱或冷却置於施配腔 5 10 15 20 室405内的物質。溫度資訊能從熱感測器460經由介面530、 端部介面連接器453、有限的再使用總成介面連接器553、 及介面535等被傳回至控制器305。此溫度資訊能被用來控 制該溫度控制裝置450的操作。當溫度控制裝置45〇係為一 加熱益時,控制器305會控制被送至溫度控制裝置45〇的電 /”l畺。送至溫度控制裝置450的電流愈多,則其會愈熱。以 此方式,該控制器3〇5能使用一反饋迴路利用得自熱感測器 460的資訊來控制該溫度控制裝置45〇的操作。任何適當類 式的控制運算法,譬如一比例微積分(PID)運算法,皆可被 用來控制該溫度控制裝置450的操作。 一要被輸入一眼睛内的物質,典型為一懸浮於一相移 轉^合物中的藥物,將被置於施配腔室405中。以此方式, /藥物和相移轉化合物會被施配腔室殼體奶的内表面接 觸仙移轉化合物在較低溫度係呈固 體或半固體狀態, 而在較向溫度會呈較似液體狀態。該化合物可藉施加電流 於舰度控制裝置_來被加熱至較呈液體狀態,並注入眼睛 内㈣成-丸體,其會經久才消餘。 同樣地,一反凝膠化合物亦可被使用。一反凝膠化合 物^較高溫度係呈固體或半固體狀態,而在-較低溫^ 曰=較像液體狀態。此-化合物可被溫度控制狀態450冷却 至較呈液體狀態,再注射於眼睛内而形成一丸體可歷久 16 200826988 地消蝕。因此,溫度控制裝置450可為一能加熱該施配腔室 405内之物質的裝置,或為一能冷却在施配腔室405中之物 質的裝置(或該兩者的組合)。在被輸入眼睛内之後,一相移 轉化合物或反凝膠化合物會經久才溶消。故能在一較長的 5 時間週期中提共一定量的藥物。使用一相移轉化合物或反 凝膠化合物將能以較少次的注射來提供較佳的藥物劑量。 在本發明之一實施例中,置於施配腔室405内的物質係 為一種藥物,其係被預先裝入該施配腔室中。於此情況下, 尖端部段205係被視為一種單次使用的可消耗產品。此一可 1〇 棄式產品能在工廠内被組合且一劑量的藥物會被裝入。 雖所示為一兩件式裝置,但第4圖的注射系統亦可為一 單件裝置。在此情況下,該尖端部段會被整合於該有限的 再使用總成中來形成單件的醫療裝置。 第5圖為依本發明一實施例之用於眼科醫療裝置的尖 15 端部段之截面圖。在第5圖中,尖端部段205包含施配腔室 殼體425,尖端部段殼體215,熱感測器460,針210,施配 腔室405,柱塞415,柱塞介面420,溫度控制裝置450,介 面530,端部介面連接器453,及一可擇的接頭430。可擇接 頭430會將針210固定於施配腔室殼體425。 20 在第5圖的實施例中,溫度控制裝置450會運作來將該 施配腔室405中的物質帶至一適當的溫度範圍中。熱感測器 460會提供溫度資訊給控制器3〇5(未示出)來控制該溫度控 制裝置450。在該物質已達到該適當的溫度範圍後,柱塞415 會作動以將該物質輸送穿過該針210而注入眼睛内。該柱塞 17 200826988 415會延伸並包含一整體的輛桿如圖所示。 第6A和6B圖係為-依本發明之原理的施配腔室之截 面圖’並有-藥物已被投注於其内。在第6A圖中,一懸浮 於-相移轉化合物6㈣的藥物已被加熱並倒人或投注於 5鈀配腔至忒體425内,而使其冷却並固化。塞頭610會被置 於該針210中來阻止懸浮在相移轉化合物6〇5中的藥物於呈 液悲或半液悲牙過§玄針210逸出。當該懸浮於相移轉化合 物605中的藥物被凝鑄於施配腔室殼體425内之後,柱塞415 會被插入如第6B圖中所示。 10 將懸浮在一相移轉化合物605中的藥物填鑄於施配腔 室殼體425内乃可容小規格的針能被使用。在一依本發明之 原理的實施例中,一25號規格的針會被使用。將一懸浮在 一相移轉化合物605中的藥物經由一小規格的針裝入施配 腔室殼體425内是不容易的。而且,在室溫下,當該相移轉 15 化合物係呈較像固體的錯狀形態時,要處理該化合物亦會 比較困難。在其係呈較似固態時要將此材料裝入一注射裝 置内可能會造成空氣滯陷,不精確的劑量等等。“熔化,,該 物質再將之注入施配腔室殼體425内乃可提供一簡單的方 式來容裝該正確劑量於一預裝的注射裝置中。 20 一懸浮在一反凝膠化合物中的藥物亦能被使用。於此 情況下,懸浮在該反凝膠化合物中的藥物會被冷却直到其 變得較呈液體,然後將之注入施配腔室殼體425内再使其升 溫並固化。 第7A〜7D圖係為一依本發明之原理的柱塞之截面 18 200826988 圖’並有一藥物已被投注於該柱塞上。第7A圖示出一柱塞, 在第7B及7C圖中,一套筒705會被置設圍繞該柱塞415,並 有一懸浮於一相移轉或反凝膠化合物710中的藥物會被投 注於該柱塞415頂上的套筒705内。套筒705具有一内表面與 5 一外表面。該内表面會容納該物質。當該物質回復至室溫 時,其將會固化而套筒7〇5會被移除。該套筒7〇5可被鉸合, 或在其内表面塗層,俾使其能被卸除。套筒7〇5亦可設有導 槽(未不出),以使其能被正確地置設於柱塞上。如第7D圖 中所不,在套筒705被移除後,柱塞415會有該藥劑和化合 1〇物710成形於其頂上。柱塞415嗣可被置入施配腔室殼體425 内。此一鑄設操作可為一預裝的注射裝置提供組裝的方便。 第8A〜8G圖係為依本發明之原理的各種不同柱塞之 截面圖。不同的柱塞構形可被使用於第7a〜7d圖所示的鑄 設操作中。在某些情況下,其最好能在該柱塞415的頂面上 15提供一形狀或紋理。此一形狀或紋理乃可使被投注入該模 内的藥物和化合物更佳地黏附於該柱塞415。較佳的黏著能
