【０００１】
【発明の属する技術分野】
本発明は透析や輸液に使用される翼付針（例えばＰＳＶ、ＡＶＦ等）、に装着する針カバー及びキャップ付針カバー並びに針カバー付翼付針の改良に関するもので、針の保護性、操作性、安全性を向上させた発明に関する。
【０００２】
【従来の技術及び発明が解決しようとする課題】
周知のように翼付針や採血針等の医療用針に装着する針キャップは、円筒形状またはテーパー付の円筒形状に形成され、針先の保護や前記医療用針を廃棄する時、安全のために再キャップをするために使用されている。しかしこれらの針キャップは廃棄するまでの問題点として、再び針に針キャップを取り付ける時、作業者の指を誤って刺したり、また針キャップを取り付けずに廃棄すれば血液が付着した針で、作業者が作業中に誤って刺してしまう危険性があった。
またアメリカ特許５，１１２，３１１号、５，４３３，７０３号、５，５６２，６３６号、５，５６２，６３７号には、針カバーの両側部に翼付針の両翼を固定するスリットを形成し、針の使用後、両翼をスリットの位置と形状にあわせてスライドして固定し、針を針カバー内に収納する発明が提案されている。しかしながら、これらの発明においても（１）針カバーを翼付針に装着する際の組み立て容易性と安定性、（２）針カバー付翼付針を患者に穿刺する時の操作性、（３）針の使用後に針カバーを被冠する時の操作性等についてさらに改良の余地があった。
【０００３】
【課題を解決するための手段】
そこで本発明者は以上の課題を解決するために鋭意検討を重ねた結果次の発明に到達した。
本発明の目的は針カバーを翼付針に装着する際の組み立て容易性と安定性の向上した針カバー及びキャップ付針カバー並びに針カバー付翼付針を提供することである。
本発明のその他の目的は針を使用した後に針カバーを被冠する時に操作性の良い針カバー及びキャップ付針カバー並びに針カバー付翼付針を提供することである。
本発明のその他の目的は使用前は針を安定して保護でき、使用後は針が露出することのない安全な針カバー及びキャップ付針カバー並びに針カバー付翼付針を提供することである。
本発明のその他の目的は患者に穿刺する時の操作性の良い針カバー及びキャップ付針カバー並びに針カバー付翼付針を提供することである。

【０００４】
【発明の実施の形態】
図１は本発明の針カバーの一例を示す概略図で（ａ）は本発明の針カバー１の正面斜視図、（ｂ）は背面斜視図、（ｃ）は同（ａ）を１８０°反対方向から見た斜視図、（ｄ）は同（ｂ）を１８０°反対方向から見た斜視図、図２は図１の針カバー１を翼付針１０（針基１３の前方に針１２を植設し、両側部に翼１４を装着し、前方外周面に針キャップ１６を装着し、後方外周面にチューブ１５を装着することにより形成されている）に装着したところの針カバー付翼付針１Ａの断面図、図３は針カバー付翼付針１Ａの使用方法の一例について時系列に示した斜視図である。図２（ａ）と図３（ａ）、図２（ｂ）と図３（ｅ）、図２（ｄ）と図３（ｆ）がそれぞれ対応している。図４（ａ）、（ｂ）はそれぞれ図３（ｆ）、（ｇ）に対応する平面図である。
本発明の針カバー１は、長手方向と、当該長手方向と略垂直に交差する側部方向を有する。長手方向は、前方部と後方部と有し、側部方向は、上部及び底部と、当該上部及び底部と略垂直に交わる第１側部と第２側部とを有する。
前記長手方向に前方部２、中腹部３及び後方部４を有する。
ストッパー８を、前記中腹部３の第１側部と第２側部の両側部に、それぞれ翼状に突出して第１側部ストッパー及び第２側部ストッパーとして形成している。
翼付針１０は、針１２と針基１３と翼１４を有する。針基１３は、長手方向と、当該長手方向と略垂直に交差する側部方向を有し、前記長手方向は前方部と後方部とを有し、前記側部方向は上部及び底部と、当該上部及び底部と略垂直に交わる第１側部と第２側部とを有する。
前記針１２の後方部を前記針基１３の前方部に装着し、前記針基１３の第１側部と第２側部の両側部に第１翼部と第２翼部とを有する翼部１４を突設して形成している。
翼部１４は、長手方向と、当該長手方向と略垂直に交差する側部方向を有し、前記長手方向は前方部と後方部とを有する。
針基１３の前方部外周面に針キャップ１６を装着し、前記針基１３の長手方向の後方部にチューブ１５を装着している。
以下の説明で、前記中腹部３の「第１側部」、「第２側部」は、わざわざ区別して記載せずに、単に「両側部」、「側部」と記載する。
また前記ストッパー８の「第１側部ストッパー」、「第２側部ストッパー」もわざわざ区別して記載せずに、単に「（翼状の）ストッパー」と記載する。
また前記翼部１４の「第１翼部」、「第２翼部」もわざわざ区別して記載せずに、単に「翼部」、「両翼」として記載する。
本発明の針カバー１は図１のように筒状に形成され、中腹部３底部に開口部５を形成し、前方部２と中腹部３と後方部４の上部外面にそれぞれ凸部７ａ、７ｂ、７ｃを形成し、前記中腹部３の両側部にストッパー８が突設されている。
前記凸部７ａ、７ｂ、７ｃは図１と図２のように略四角形状でかつ板状に形成され、凸部７ｂを除いてその針カバー１の幅方向の断面は針カバー１の断面と実質的に同一ないし大きく形成することにより、作業者が指で把持しやすい形状となっている。
【０００５】
前記ストッパー８は図１のように中腹部３の両側部に翼状に突出して形成されている。
本発明でストッパーの形状が「翼状」であるとは、要するに中腹部３の両側部に突出して、両翼を上側または下側に折り曲げ可能な板状のものを意味し、図１のような「翼状」の形態そのもののみならず後述する図６のような略四角形状や略半円形状等のものも含む。
図１ではストッパー８の形状は後方部４側の端部に切欠部８ａが形成されており、翼付針１０の翼部１４が切欠部８ａに係止しやすいようになっている。ストッパー８の形状は図１に記載したものに限定されず、要するに図３（ｇ）のように翼付針１０の翼部１４を係止できる形状であれば何でも良い。
またストッパー８の形成位置も図１では中腹部３のほぼ中央に形成されているが、前方部２と翼付針１０の装着形態に応じて自由に設定することができる。
また後方部４底部には図１（ｂ）のように針カバー１の長さ方向に沿って翼付針１０のチューブ１５を挿通することのできるスリット９が形成されている。
【０００６】
次に針カバー１を翼付針１０に装着して針カバー付翼付針１Ａを組立てる方法の一例について説明する。
図１（ａ）の向きの針カバー１の下から翼付針１０の針１２と針基１３を開口部５を経て針カバー１の内部に収納するとともにチューブ１５をスリット９を経て後方部４に装着する。この状態では、図２（ａ）のように針キャップ１６基部の外周面が前方部２内周面に接することにより翼付針１０が針カバー１に固定されるとともに針１２が針キャップ１６に被冠された状態に維持される。
【０００７】
以下、図３（ａ）から（ｇ）に基づいて針カバー付翼付針１Ａの使用方法の一例について時系列に説明する。
同（ａ）のように針カバー付翼状針１Ａを針カバー１の凸部７ａ、７ｂ、７ｃを上に向けた状態にする。
同（ｂ）のように左手（右手）の親指と人差し指で凸部７ｃの両側部を軽くつまみ、右手（左手）の親指と人差し指で翼部１４の両翼を挟んで上に向けて両翼を重ね合わせる。
同（ｃ）のように針キャップ１６をはずして翼付針１０の針１２を針カバー１より露出する。
同（ｄ）のように右手（左手）の親指と人差し指で翼部１４の両翼を上に向けて両翼を重ね合わせた状態で体勢を整えて患者の腕等に穿刺する。
同（ｅ）のように患者の腕等に穿刺した後、翼部１４を水平に戻して穿刺部位が動かないように翼部１４と皮膚をテープで固定する。
同（ｆ）のように穿刺した針カバー付翼付針１Ａの針１２を穿刺部から抜く時はテープを剥ぎ取り穿刺部に消毒綿をあて、左手（右手）の薬指で前記消毒綿の上から穿刺部を押さえるとともに中指と人差し指を凸部７ａと凸部７ｂないし凸部７ｂと凸部７ｃの間の壁面に添えて凸部７ａ、７ｂがそれぞれの指先に掛かるようにし、例えば図２（ｃ）のように右手（左手）で後方部４付近のチューブ１５を引っ張り翼付針１０を針カバー１内に収める。
同（ｇ）のように翼部１４の両翼を上側に折り曲げることにより、翼部１４は前記ストッパー８と交差して係止され、再び翼付針１０が針カバー１の前方部２方向にスライドすることがなく、翼付針１０の針１２が針カバー１より露出しない状態を維持できる。
【０００８】
また図５（ａ）、（ｂ）のように前記針カバー１の代わりに後方部４側の端部に突部８ｂを突設したストッパー８Ａを有する針カバー１１を使用し、ストッパー８Ａの両翼を図５（ｂ）のように下側に折り曲げることにより翼部１４にストッパー８Ａを係止することができる。
【０００９】
図６は本発明の針カバーの一例を示す概略図で（ａ）は本発明の針カバー２１の正面斜視図、（ｂ）は背面斜視図、（ｃ）は同（ａ）を１８０°反対方向から見た斜視図、（ｄ）は同（ｂ）を１８０°反対方向から見た斜視図、図７は図６の針カバー２１を翼付針１０（針基１３の前方に針１２を植設し、両側部に翼１４を装着し、前方外周面に針キャップ１６を装着し、後方外周面にチューブ１５を装着することにより形成されている）に装着したところの針カバー付翼付針１１Ａの断面図、図８は針カバー付翼付針１１Ａの使用方法の一例について時系列に示した斜視図である。図７（ａ）と図８（ａ）、図７（ｂ）と図８（ｅ）、図７（ｄ）と図８（ｇ）がそれぞれ対応している。
針カバー２１は前記針カバー１（１１）の翼状のストッパー８（８Ａ）を設ける代わりに略四角形状の翼状のストッパー８Ｂを中腹部３の両側部に突設したものである。
針カバー２１も針カバー１と同様に翼付針１０に装着して針カバー付翼付針１Ａと同様に針カバー付翼付針１１Ａを組み立てることができる。針カバー付翼付針１１Ａも図８（ａ）から（ｇ）のように針カバー付翼付針１Ａと同様に使用されるが、図３の針カバー付翼付針１Ａが図３（ｇ）のように翼部１４の両翼を上側に折り曲げるのに対し、針カバー付翼付針３１Ａは図８（ｇ）のようにストッパー８Ｂの両翼を下側に折り曲げて翼部１４を係止する点で異なっている。
【００１０】
図９は本発明の針カバーのその他の実施例を示す概略図で、（ａ）は針カバー３１の正面斜視図、（ｂ）は使用状態の断面図である。
針カバー３１は前記針カバー１のストッパー８の代わりに中腹部３の両側部に形成したストッパー８Ｃに前方部２側の端部と後方部４側の端部にそれぞれ切欠部８ｄを形成したものである。
