Abstract
Description
この出願は、2008年12月30日に出願された米国仮出願第61/141,584号および2009年10月15日に出願された第61/252,076号による優先権の恩典を主張するものであり、これらの両仮出願は参照によりそれらの内容全体が本明細書に組み入れられる。
支持用フレーム
特定の実施形態のセンシング素子220は内科患者の測定部位からの音響振動を感知するように構成されている。1つの実施形態においては、センシング素子220は、参照によりその内容全体が本明細書に組み入れられる米国特許第6,661,161号および第’883号出願に記載されているものなどの圧電性フィルムである。尚も図2D−Eを参照すると、センシング素子220は上方部分272および下方の平坦な部分262を含んでいる。以降で検討されているように、組み立てられた配置構成において、上方部分272の上面は、PCB222に設けられた電気的な接触子と接触する電気的接触子を含んでおり、これにより、本センサシステムによる処理のため、センシング素子220からの電気的な信号を伝送することが可能に成されている。センシング素子220は、フレーム218の周りをくるみ、且つ、フレーム218に順応することができるように、総体的に「C」字形の配置構成で形成されていてよい。本明細書で開述されている実施形態によるセンシング素子は、2008年3月7日に出願された米国特許出願第12/044,883号においても見出すことができ、その特許出願は参照によりそれの内容全体が本明細書に組み入れられる。幾つかの実施形態においては、センシング素子220は、トルマリン、石英、トパズ、甘藷糖および/またはRochelle塩(酒石酸カリウムナトリウム四水和物)のうちの1つもしくはそれ以上の結晶を含んでいる。別の実施形態においては、センシング素子220は、石英類似結晶、例えばベルリナイト(AlPO4)もしくはオルトリン酸ガリウム(GaPO4)など、またはペロブスカイトもしくはタングステン−ブロンズ構造を伴ったセラミックス(BaTiO3、SrTiO3、Pb(ZrTi)O3、KNbO3、LiNbO3、LiTaO3、BiFeO3、NaXWO3、Ba2NaNb5O5、Pb2KNb5O15)を含んでいる。
戻って図2D−Eを参照しながら説明すると、特定の実施形態の結合層224(時として絶縁層とよばれることもある)はエラストマであり、且つ、この結合層の両方の面に接着材を有している。別の実施形態においては、結合層224は、ゴム、プラスチック、布テープや発泡テープなどのテープもしくは接着材フィルム、またはそれの両面に接着材を有する他の圧縮性材料である。例えば、1つの実施形態においては、結合層224は、高粘着性で且つ高剥離性のアクリル系接着材により両面を皮膜形成された順応性ポリエチレンフィルムである。幾つかの実施形態における結合層224は、厚みが約2、4、6、8または10ミリメートルである。
電気的なノイズ遮蔽バリアは、外部の電気的なノイズからセンシング素子を電気的に遮蔽することができる。幾つかの実施形態においては、静電遮蔽バリアは、圧電性センシング素子の周りにファラデー箱を形成し、且つ、外部の電気的なノイズをその圧電性センシング素子の電極に実質的に等しく分配する、1つもしくはそれ以上の層を含むことができる。更に、その遮蔽バリアは、圧電素子の表面形状が変化するときに、その圧電素子の表面形状にフレキシブルに順応し、これにより、遮蔽およびセンサ性能を改善することができる。
本センサは、有利なことに本センサにより測定されるべき信号源(例えば患者の皮膚)とセンシング素子との間のカップリング状態を改善する、音響カプラまたはバイアス負荷エレメントも含んでいてよい。音響カプラは、一般的には、緊張状態になるようにセンシング素子にバイアスをかけるために、センシング素子に圧力を加えるように位置付けされたカップリング部分を含んでいる。例えば、音響カプラは、そのような張力を提供する1つもしくはそれ以上の隆起部、ポストまたは凸状部分を含んでいてよい。それらの隆起部、ポストまたは凸状部分は、カプラの内面、カプラの外面、または内面と外面の両方に位置付けられていてよく、また、それらの隆起部などは、センシング素子にわたって圧力を均等に分配するように作用することもできる。
PCB222は、PCB222のどちらかの面または両方の面に裁置された様々な電子的コンポーネントを含んでいる。センサアセンブリが組み立てられて、PCB222が上方のフレームの空洞230に配置されたときには、PCB222の電子的コンポーネントのうちの幾つかは前述の上方フレーム空洞230の上へ伸びていてよい。スペースに関する必要条件を軽減し、且つ、電子的コンポーネントがセンサアセンブリの動作に悪影響を及ぼすのを防ぐため、それらの電子的コンポーネントは低プロフィールの表面載置型デバイスであってよい。電子的コンポーネントは、しばしば、通常の半田付け技術を用いて、例えばフリップチップ半田付け技術を用いてPCB222に接続される。フリップチップ半田付けは、半田付けされた電子的コンポーネントのプロフィールをコントロールするため、深さが予測可能であるような小さな半田隆起部を使用する。1つの実施形態においては、内側銅シールド226の4つのタブ268および外側銅シールド228の上方の平面的な部分273がPCB222に半田付けされ、静電遮蔽バリアがPCB222にカップリングされる。
図6Aは、図1A−Cに示されている生理学的モニタのうちのいずれかと共に使用するのに適したセンサアセンブリ601を含むセンサシステム600の別の実施形態の部分を描いた上面透視図である。センサアセンブリ601は、センサ615、ケーブルアセンブリ617およびコネクタ605を含んでいる。センサ615は、1つの実施形態においては、センサ・サブアセンブリ602および取り付け用サブアセンブリ604を含んでいる。1つの実施形態のケーブルアセンブリ617はケーブル607および患者用アンカ603を含んでいる。センサケーブル607を介して様々なコンポーネントが相互に接続される。センサコネクタ605は、モニタモニタケーブルまたは何らかの他のメカニズムを通じるなどして、生理学的モニタモニタ(図示せず)に取り外し可能に取り付けることができる。1つの実施形態においては、センサアセンブリ601は無線接続を介して生理学的モニタモニタと通信する。
本音響センサは、予め定められた量の力で本センサを患者の皮膚に押し付けるように構成された取り付け用サブアセンブリも含むことができる。その取り付け用サブアセンブリは、センサから延びる翼様の伸展部またはアームなどの、センサの周りに対称に配置された側方伸展部を含むことができる。別の実施形態においては、取り付け用サブアセンブリは、有利なことに音響学的測定部位への取り付け用サブアセンブリの一様な付着を可能にする、円形または丸められた形状を有している。取り付け用サブアセンブリは、有利にはバネ様の仕方で本センサを患者に押し付けるように作用するために、曲げられたときにその形状を保持するようにバイアスが掛かるバネまたは他の材料を含め、プラスチック製、金属製または何らかの弾力性材料を含むことができる。更に、取り付け用サブアセンブリは、患者から剥離することなく接着材の作用により患者に取り付けることができるように細長いメンバと相互作用し得る取り付け用の層も含むことができる。
ケーブルのグイッとした引っ張り、ビクッとした動きまたは牽引などの動きは、センサアセンブリ201と患者との間での付着性接続に応力をもたらし得る。そのような応力は、例えば患者の動き、モニタの動き、または医療従事者による偶発的なケーブルの引っ張りなどによって引き起こされ得る。それ故、ケーブルの両端間におけるあるポイントでケーブルを身体に確保し、これにより、センサアセンブリ201と患者との間での付着性接続からケーブルの潜在的な動きをデカップリングすることは有益であり得る。そのようなものとして、ケーブルアセンブリは、有利なことにケーブルの両端間におけるあるポイントでケーブルを患者に確保する患者用アンカを含むことができる。患者用アンカは、例えば接着材の作用によりケーブルを身体に確保する1つもしくはそれ以上のパネルを含むことができる。
