Description

本発明は、輸液や輸血或いは採血の際などに用いられる翼状針の保持具に関するものである。  The present invention relates to a winged needle holder used for infusion, blood transfusion or blood collection.

従来、輸液や輸血或いは採血の際などに第７図に示すような翼状針６が用いられている。この翼状針６は、先端に管状針６１が突設されているとともに基端部６２に一端を点滴容器など（図示せず）に接続したチューブ６３が連結された軸体６４に例えば塩化ビニル樹脂などの薄板により形成された一対の羽根６５，６５が蝶のように拡設された構成を有し、血管に差し込む際に、左右の羽根６５，６５を摘んで操作することによりきわめて安定した状態で血管への差し込みを可能にするとともに、差し込んだ後は左右の羽根６５，６５を拡げて例えば絆創膏や粘着テープ等で身体に固定することにより長時間にわたって安定した状態で薬液や血液を注入することができるなどの利点を有している。
そして、前記翼状針６も普通に用いられる注射針と同じくキャップ６６を嵌めた状態で流通することにより使用時まで滅菌状態が保持されている。従って、使用時にキャップ６６を外してそのまま、患者の身体に差し込めばよい。
ところが、輸液や輸血或いは採血などを行うには管状針の針先を確実に血管などの身体の限られた部位に差し込む必要があり、差し込みに熟練を要したり、患者によっては差し込み部位が確認しにくい場合があり、差し込み操作を複数回にわたって繰り返すことで所定の位置に針を差し込んでいるのが一般的である。
このとき、医師や看護士は一旦患者の身体から翼状針を抜き取った後に、次に差し込む迄の間に抜き取った患部の止血や再滅菌、消毒等の処置をする必要があるが、抜き取った翼状針を片手に持ったままだとこれらの処置を行うことが困難であり、両手で作業するためには抜き取った翼状針を離すことになるが、一旦身体に差し込んだ翼状針の針先には患者の血液や体液等が付着しており、感染症のおそれがあることからそのまま手を離して放置することができない。
そこで、再度、キャップを被冠させてから手を離し、両手で止血や清浄の処置が終わった後で、再びキャップを外して差し込み操作を繰り返すことが行われているが、全ての作業が終わるまでキャップを清潔な状態で保管しておく必要があるとともに、差し込み作業中に尖った針先を口の狭いキャップに差し込むことはきわめて困難で患者の血液や体液等が付着した針先で指先を刺すことにもなり、きわめて危険である。また、床などに放置した翼状針が汚染されたり踏まれたりして破損するなどの心配もあり、床面から拾い上げる手間も掛かる。
また、翼状針についてキャップを被せる際などに誤って指などに刺してしまう事故を防止するものが特開平１−７６８７３号公報、特開平８−８９５７３号公報、特開２０００−１４７８１号公報などに提示されているが、これらはいずれも使用後の処理を念頭にしたものであり、翼状針を再使用する場合に採用することはできない。Conventionally, a winged needle 6 as shown in FIG. 7 is used for infusion, blood transfusion or blood collection. The winged needle 6 has, for example, a vinyl chloride resin attached to a shaft body 64 having a tubular needle 61 projecting from the distal end and a proximal end 62 connected to a tube 63 having one end connected to an infusion container or the like (not shown). A pair of blades 65, 65 formed by thin plates such as butterflies are expanded like a butterfly, and when inserted into a blood vessel, the left and right blades 65, 65 are picked up and operated in an extremely stable state Enables insertion into the blood vessel, and after insertion, expands the left and right wings 65, 65 and injects liquid medicine and blood in a stable state for a long time by fixing it to the body with, for example, adhesive bandage or adhesive tape Has the advantage of being able to.
The winged needle 6 is kept in a sterilized state until it is used by being distributed with the cap 66 fitted in the same manner as a commonly used injection needle. Therefore, the cap 66 may be removed and inserted into the patient's body as it is in use.
However, in order to perform infusion, blood transfusion, blood collection, etc., it is necessary to securely insert the tip of the tubular needle into a limited part of the body, such as a blood vessel. In many cases, the needle is inserted into a predetermined position by repeating the insertion operation a plurality of times.
At this time, doctors and nurses must remove the ptery needle from the patient's body and then take measures such as hemostasis, re-sterilization, and disinfection of the affected area until the next insertion. If you hold the needle in one hand, it is difficult to perform these procedures. To work with both hands, the winged needle will be released. Blood and body fluids are attached to it, and there is a risk of infection, so it is impossible to leave it as it is.
Therefore, once the cap is put on the crown again, the hands are released, and after the hemostasis and cleaning procedures are completed with both hands, the cap is removed again and the insertion operation is repeated, but all operations are completed. It is necessary to keep the cap clean until it is inserted, and it is extremely difficult to insert a sharp needle tip into the cap with a narrow mouth during the insertion work. It can be stabbed and extremely dangerous. In addition, there is a concern that the winged needle that is left on the floor is contaminated or damaged by being stepped on, and it takes time to pick it up from the floor.
In addition, JP-A-1-76873, JP-A-8-89573, JP-A-2000-14781, and the like prevent accidents in which a finger or the like is accidentally stuck into a winged needle when the cap is put on. Although presented, these are all intended for post-use processing and cannot be employed when re-using the winged needle.

本発明は上記実情に鑑みてなされたものであり、輸液や輸血或いは採血などを行う際に、翼状針の先端に設けられている針先のキャップを外したままの状態で翼状針を簡単に且つ容易に取り外し可能に片手で保持させて、安心して患者の身体の清浄や止血作業を行うことができるばかりか、キャップを外した管状針により患者を含めて医師や看護士が汚染される心配をしないで作業をすることができる翼状針の保持具を提供するものである。
上記目的を達成するため本発明は、点滴台の支柱へ止着するための止着部に翼状針の保持部が横方向に突設されており、前記保持部が前記翼状針の羽根を起てた状態で一方の羽根における両側面を挟持する一対の弾性挟持片とその下側に配置された前記翼状針の羽根の外周縁を支持するための支持部片とを有していることを特徴とする。
止着部を点滴台の支柱における所望の高さ位置に止着し、キャップを外した状態の翼状針の羽根を起てた状態で針先を上に向けて保持部に差し込むだけで、翼状針は羽根の両側面が一対の弾性挟持片により挟持されるとともに羽根の外周縁の下端が前記弾性挟持片の下側に配置された支持部片に支持され、また、羽根を掴んでそのまま引き抜くことで離脱する。
また、本発明において、前記止着部と保持部とが適宜の弾性と剛性を有する硬質合成樹脂により一体的に形成されている場合には、例えば、射出成形などにより簡単且つ安価に製造することが可能であり、前記保持部を形成する一対の弾性挟持片における互いの対向面の先端側と頂面側の端縁が傾斜面にそれぞれ形成されている場合には、翼状針の羽根部を差し込むときに差し込み部が拡開しているので差し込み易く、前記止着部と保持部との間に所定の空間が形成されている場合には、凹が形成されないので塵埃や各種の汚染物などが溜まる箇所がなく清潔に保てるとともに洗浄なども簡単である。
更に、本発明において、前記止着部と保持部の長さが少なくとも前記翼状針の一方の羽根の長さよりも長く形成されている場合には確実に保持することができ、特に、針先を支柱側に傾けた状態で保持させることにより保持中の針が刺さる事故を防止することができ、前記止着部が、内側を前記点滴台の支柱への圧着面とした平面においてＣ形を呈する場合には、止着部を開口部を介して横方向に向けて支柱に差し込むだけの簡単な作業で支柱に止着させることが可能である。
以上、本発明によれば、輸液や輸血或いは採血などを行う際に、翼状針の先端に設けられている針先のキャップを外したまま状態で片手の操作で翼状針を簡単に且つ取り外しも容易に所望の高さ位置に確実にもう一方の手で止血等の処置をしながらでも保持させることができ、その後は再度翼状針を掴んで抜き取るまでの間は安心して両手を用いて患者の身体の清浄や止血作業を行うことができる。また、キャップを再度嵌め直したり翼状針の部分を床に放置することも要しないので翼状針の差し込み操作が安全に行われ特に、安価に多量に製造して供給することができ耐久性にも優れているので経済的にも優れている。The present invention has been made in view of the above circumstances, and when performing infusion, blood transfusion, blood collection, etc., the winged needle can be easily removed with the cap of the needle tip provided at the tip of the winged needle being removed. In addition, it can be easily removed and held with one hand to clean the patient's body and perform hemostasis without worry, and the tubular needle with the cap removed may contaminate doctors and nurses including the patient. It is intended to provide a winged needle holder which can be operated without performing the above-mentioned.
In order to achieve the above object, according to the present invention, a holding part for a winged needle protrudes in a lateral direction at a fixing part for fixing to a drip stand column, and the holding part raises a blade of the winged needle. A pair of elastic clamping pieces for holding both side surfaces of one of the blades in a bent state, and a support piece for supporting the outer peripheral edge of the blade of the winged needle disposed below the pair of elastic clamping pieces Features.
Just fix the fixing part at the desired height position on the drip stand column, and with the winged needle blade with the cap removed, raise the needle tip upward and insert it into the holding part. The needle is held on both sides of the blade by a pair of elastic clamping pieces, and the lower end of the outer peripheral edge of the blade is supported by a support piece disposed on the lower side of the elastic clamping piece. To leave.
Further, in the present invention, when the fastening part and the holding part are integrally formed of a hard synthetic resin having appropriate elasticity and rigidity, for example, it can be easily and inexpensively manufactured by injection molding or the like. In the case where the end edges of the opposing surfaces of the pair of elastic clamping pieces forming the holding portion are respectively formed on the inclined surfaces, the blade portion of the winged needle is Since the insertion part is widened when inserting, it is easy to insert, and when a predetermined space is formed between the fastening part and the holding part, a concave is not formed, so dust, various contaminants, etc. It is easy to clean as there are no spots where it accumulates.
Further, in the present invention, when the length of the fastening portion and the holding portion is at least longer than the length of one of the blades of the winged needle, it can be reliably held. By holding it in a tilted state on the support column side, it is possible to prevent an accident that the needle being held is stuck, and the fastening portion exhibits a C shape on a plane whose inner surface is a pressure contact surface to the support column of the drip stand. In this case, it is possible to fix the fixing portion to the support column by a simple operation of inserting the fixing portion into the support column in the lateral direction through the opening.
As described above, according to the present invention, when performing infusion, blood transfusion, blood collection, etc., the wing needle can be easily and removed by one-handed operation with the needle tip cap provided at the tip of the wing needle removed. It can be easily held at the desired height position even while performing treatment such as hemostasis with the other hand, and after that, the patient's The body can be cleaned and hemostatic. In addition, it is not necessary to refit the cap or leave the winged needle part on the floor, so the winged needle can be inserted safely, and can be manufactured and supplied in large quantities at a low cost. Because it is excellent, it is economically superior.

FIG. 7 is an explanatory view of a winged needle, and is an explanatory view showing different usage states of the illustrated embodiment.

本発明の好ましい実施の形態を図面に基づいて詳細に説明する。
第１図乃至第５図は本発明の好ましい実施の形態を示すものであり、本発明である翼状針の保持具１は、例えば硬質のポリプロピレン樹脂のような適宜の弾性と剛性とを有する材料により射出成形などにより点滴台７の支柱７１へ止着するための止着部２とこの止着部２から横方向に突設している前記第７図に示した翼状針６の保持部３とが一体的に形成されている。従って、製造が容易で安価に多量に生産することができる。
更に詳しく説明すると、前記止着部２は所定の内径（例えば使用する支柱の外径程度）を有していて一側に少なくとも内径よりも幅狭の開放部２１を有する平面がＣ形で適宜の厚さを有する半筒形を呈しているとともに開放部２１を形成する両開放端には円柱状の膨出部２２，２２が形成されている。
また、前記止着部２における外周面２３の前記開放部２１と対向する箇所には前記第６図に示した翼状針６の保持部３が横方向に突設されており、この保持部３は翼状針６を挟持するための一対の弾性挟持片３１，３１とその下側に配置された前記翼状針６の羽根６５の外周縁６７を支持するための支持部片４とから構成される。
特に本実施の形態では、弾性挟持片３１，３１は基端が一体化して前記止着部２における外周面２３に連設されており、先端側が互いに遊離していて対向面３２，３２が前記翼状針６の一方の羽根６５を起てた状態で両側面を挟持するものであり、特に、前記対向面３２，３２は平面において長さ方向の中央部に互いに接近するように（少なくとも使用する前記第７図に示した翼状針６の羽根６５の厚さよりも接近指せた状態）弓形に形成されて先端に向けて拡開しているとともに互いの対向面３２，３２の先端側と頂面側の端縁が傾斜面３３，３３，３４，３４にそれぞれ形成されて上方に向けて拡開している。
また、前記支持部片４は、前記弾性挟持片３１，３１の下方に前記弾性挟持片３１，３１との間に空間４１を形成して前記弾性挟持片３１，３１とほぼ同等の長さで前記弾性挟持片３１，３１とほぼ平行に突設される。
以上の構成を有する本実施の形態である保持具１は、第５図に示すように、前記止着部２の開放部２１を介して点滴台７に立設される支柱７１の所望の高さ位置に止着する。
このとき、止着部２が使用する支柱７１の外径よりも小径の場合には止着部２を開放部２１を介して横方向から挿入すると、止着部２自身が有する弾性により、更には開放部２１を形成する両開放端に設けた円柱状の膨出部２２，２２により支柱７１を押圧するのでそのまま所定の位置に止着させることができ、また、この押圧力に抗して止着部２を開放部２１を介して横方向に引き抜くことにより簡単に支柱７１から取り外すことができる。尚、止着部２の内径が支柱７１に対して大きくて差し込んだだけでは止着が困難な場合には、例えば、布や紙、或いはゴムや合成樹脂材など比較的摩擦係数が大きく柔軟で変形し易い材料で形成された隙間部材を止着部２と支柱７１との間に介在させればよい。
また、保持具１は医師や看護士など使用者の身長などに合わせて所望の高さ位置に止着することにより使い勝手がよく使用することができ、特に本実施の形態では前述の如く着脱操作が容易なので使用者各人に適した高さに止着させることができる。尚、通常は支柱７１の止着位置よりも上方に薬液や血液を収納したバックなどの容器が吊り下げられており（図示せず）、それらの容器からチューブ６３が垂下しているのでこのチューブ６３に干渉しない方向に保持部３が位置するように止着するとよい。
そして、第６図に示すように、前記チューブ６３の先端に接続された翼状針６を保持させるのであるが、保持は、点滴容器や輸血容器を点滴台７の支柱７１にセットしたとき、次いで、キャップ６６を外したとき、翼状針６を差し直すとき、更には点滴や輸血が終了したときなど手にした翼状針６を一旦どこかに起きたい場合のいずれのときにも保持させることができる。
本実施の形態では翼状針６の保持具１への保持は、第５図および第６図に示すよう翼状針６を管状針６１が上方に向くような状態で羽根６５，６５を起てた状態で一方の羽根６５を掴んでもう一方の羽根６５を、そのまま弾性挟持片３１，３１の対向面３２，３２に上方から横方までの任意の差し込み角度で差し込むだけで簡単且つ確実に保持される。
このとき、特に本実施の形態では、前記対向面３２，３２は平面において長さ方向の中央部に互いに接近するように弓形に形成されて先端に向けて拡開しているとともに互いの対向面３２，３２の先端側と頂面側の端縁が傾斜面３３，３３，３４，３４にそれぞれ形成されて上方および前方である差し込み側に向けて拡開しているので、拡開した箇所に羽根６５を容易に差し込し込むことができるばかりか、弾性挟持片３１，３１は基端が閉成して止着部２に連続しているとともに下方に支持部片４が延設されているので差し込み位置を加減することなく羽根６５の外周縁６７が止着部２と支持部片４に当接して進行が停止するまで差し込めばよく、所定の保持位置に容易に保持させることが可能で、安定した保持状態を維持させることができ、抜き取る場合には、保持具１から突出している羽根６５を掴んでそのまま上方から横方向にわたる方向に引き抜けばよく、着脱がきわめて簡単である。
また、本実施の形態では、特に、翼状針６を保持させるときに、第６図に示すように、翼状針６を管状針６１を支柱７１側に傾斜させておくことにより、保持されている翼状針６を掴むときに誤って管状針６１に触れたり、管状針６１が刺ったりする心配がない。
更に、本実施の形態は、弾性挟持片３１，３１と支持部片４との間に空間４１が形成されているので全体として凹部がなく、汚染物や塵埃などが溜まる心配がなく洗浄も容易でいつでも清潔に保つことができる。
更にまた、本実施の形態は、止着部２が顔で弾性挟持片３１，３１を長耳とした兎の顔を連想させることから外観的にも美麗であるとともに親しみやすいという意匠的な効果も併有している。Preferred embodiments of the present invention will be described in detail with reference to the drawings.
1 to 5 show a preferred embodiment of the present invention. A winged needle holder 1 according to the present invention is a material having appropriate elasticity and rigidity, such as hard polypropylene resin. The fixing part 2 for fixing to the column 71 of the drip stand 7 by injection molding or the like, and the holding part 3 of the winged needle 6 shown in FIG. 7 projecting laterally from the fixing part 2 And are integrally formed. Therefore, it is easy to manufacture and can be produced in large quantities at low cost.
More specifically, the fastening portion 2 has a predetermined inner diameter (for example, the outer diameter of a supporting column to be used), and a plane having an open portion 21 that is at least narrower than the inner diameter on one side is appropriately C-shaped. Cylindrical bulging portions 22 and 22 are formed at both open ends forming the open portion 21 and having a semi-cylindrical shape having a thickness of 1 mm.
In addition, a holding portion 3 for the winged needle 6 shown in FIG. 6 is provided in a projecting manner in a lateral direction at a position of the outer peripheral surface 23 of the fastening portion 2 facing the opening portion 21. Is composed of a pair of elastic clamping pieces 31, 31 for clamping the winged needle 6 and a support piece 4 for supporting the outer peripheral edge 67 of the blade 65 of the winged needle 6 disposed below the pair of elastic clamping pieces 31, 31. .
In particular, in the present embodiment, the elastic clamping pieces 31 and 31 are integrated at the base ends and connected to the outer peripheral surface 23 of the fastening portion 2, the distal ends are separated from each other, and the opposing surfaces 32 and 32 are formed as described above. Both side surfaces are sandwiched with one blade 65 of the winged needle 6 raised, and in particular, the opposed surfaces 32 and 32 are close to each other in the longitudinal direction in the plane (at least used). The state in which the blade 65 of the winged needle 6 shown in FIG. 7 is closer than the thickness of the blade 65) It is formed in an arcuate shape and expands toward the tip, and the tip side and the top surface of the opposing surfaces 32, 32. Side edges are formed on the inclined surfaces 33, 33, 34, and 34, respectively, and expand upward.
Further, the support piece 4 is formed with a space 41 between the elastic holding pieces 31 and 31 below the elastic holding pieces 31 and 31 and has a length substantially equal to the elastic holding pieces 31 and 31. The elastic pinching pieces 31 and 31 are projected substantially in parallel.
As shown in FIG. 5, the holder 1 according to the present embodiment having the above-described configuration has a desired height of a column 71 erected on the drip stand 7 through the opening portion 21 of the fastening portion 2. Secure in position.
At this time, when the fastening part 2 is smaller than the outer diameter of the support 71 used by the fastening part 2, the fastening part 2 is inserted from the lateral direction through the opening part 21. Since the column 71 is pressed by the columnar bulging portions 22 and 22 provided at both open ends forming the open portion 21, it can be fixed at a predetermined position as it is, and resists this pressing force. The fastening part 2 can be easily detached from the support 71 by pulling it out in the lateral direction via the opening part 21. In addition, in the case where it is difficult to fix simply by inserting the inner diameter of the fixing portion 2 with respect to the column 71, for example, cloth, paper, rubber, synthetic resin material or the like has a relatively large friction coefficient and is flexible. What is necessary is just to interpose the clearance gap member formed with the material which is easy to deform | transform between the fastening part 2 and the support | pillar 71. FIG.
Further, the holder 1 can be used conveniently by being fixed at a desired height position according to the height of the user such as a doctor or a nurse. In particular, in the present embodiment, the attaching / detaching operation is performed as described above. Because it is easy, it can be fixed at a height suitable for each user. Usually, a container such as a bag containing a chemical solution or blood is suspended above the fixing position of the column 71 (not shown), and the tube 63 is suspended from these containers. It is good to fix so that the holding | maintenance part 3 may be located in the direction which does not interfere with 63. FIG.
Then, as shown in FIG. 6, the winged needle 6 connected to the tip of the tube 63 is held. When the drip container or the blood transfusion container is set on the support column 71 of the drip stand 7, When the cap 66 is removed, when the winged needle 6 is reinserted, or when the drip or blood transfusion is completed, the winged needle 6 that has been held in hand can be held at any time. it can.
In the present embodiment, the winged needle 6 is held by the holder 1 by raising the blades 65 and 65 with the tubular needle 61 facing upward as shown in FIGS. 5 and 6. By simply holding one blade 65 in the state and inserting the other blade 65 as it is into the opposing surfaces 32, 32 of the elastic clamping pieces 31, 31, at an arbitrary insertion angle from above to the side, it is easily and reliably held. The
At this time, particularly in the present embodiment, the facing surfaces 32, 32 are formed in an arch shape so as to approach each other in the longitudinal direction in the plane, and are expanded toward the tip, and facing each other. Since the end edges on the front end side and the top surface side of 32 and 32 are formed on the inclined surfaces 33, 33, 34 and 34, respectively, and are expanded toward the insertion side which is the upper side and the front side, Not only can the blade 65 be inserted easily, but the elastic clamping pieces 31, 31 are closed at the base end and are continuous with the fastening portion 2, and the support piece 4 is extended downward.
