Description

採血管ホルダー及び採血キットBlood collection tube holder and blood collection kit
　本発明は、採血管ホルダー及び採血キットに関する。 The present invention relates to a blood collection tube holder and a blood collection kit.
　従来、血液検査等で血液試料を採取する際には、採血キットが使用される。採血キットは、血管に穿刺される針管を備えるいわゆる翼状針（翼付針）等の採血具で生体から採血し、この採血した血液試料を採血管ホルダーに保持される真空採血管に貯留するものであり、採血具と、コネクタを介して該採血具に接続され、真空採血管を保持する採血管ホルダーとを備える。 Conventionally, a blood collection kit is used when collecting a blood sample in a blood test or the like. A blood collection kit is a blood collection tool such as a so-called winged needle (winged needle) equipped with a needle tube that is pierced into a blood vessel to collect blood from a living body, and the collected blood sample is stored in a vacuum blood collection tube held in a blood collection tube holder. It is provided with a blood collection tool and a blood collection tube holder which is connected to the blood collection tool via a connector and holds a vacuum blood collection tube.
　前記採血管ホルダーとして、例えば、中空有底円筒状の採血管ホルダー本体と、該採血管ホルダー本体の内周面に内嵌されて該採血管ホルダー本体の中空部に挿入されるシリンジ等の採血管を着脱自在に保持する保持部材とを備えるものが知られている（例えば、特許文献１参照）。 As the blood collection tube holder, for example, a hollow bottomed cylindrical blood collection tube holder main body and a syringe or the like that is fitted inside the inner peripheral surface of the blood collection tube holder body and inserted into the hollow portion of the blood collection tube holder body are collected. Those provided with a holding member for detachably holding a blood vessel are known (see, for example, Patent Document 1).
　特許文献１記載の採血管ホルダーは、前記採血管ホルダー本体の底部に取着された針基に支持されて該採血管ホルダー本体の中空部に突出する中空の針管を備えており、該採血管ホルダー本体の中空部に前記シリンジ等の採血管が挿入されると該針管が採血管を貫通し、採血した血液試料が該針管を介して該採血管に導入される。また、特許文献１記載の採血管ホルダーにおいて、前記保持部材は複数の圧接部材を備えており、該圧接部材は、前記採血管ホルダー本体の中空部に前記シリンジ等の採血管が挿入されたときに該採血管ホルダー本体の内周面側に揺動する一方、それ自体の弾性力により該採血管の外周面に圧接する。この結果、前記採血管ホルダーは、採血した血液試料が前記採血管に導入される間、前記採血管の外周面に圧接する前記圧接部材により該採血管を保持し、前記採血管ホルダー本体の中空部から該採血管が脱落することを防止することができる。 The blood collection tube holder described in Patent Document 1 is provided with a hollow needle tube that is supported by a needle base attached to the bottom of the blood collection tube holder body and projects into the hollow portion of the blood collection tube holder body. When a blood collection tube such as a syringe is inserted into the hollow portion of the holder body, the needle tube penetrates the blood collection tube, and the collected blood sample is introduced into the blood collection tube via the needle tube. Further, in the blood collection tube holder described in Patent Document 1, the holding member includes a plurality of pressure contact members, and the pressure contact member is used when a blood collection tube such as a syringe is inserted into a hollow portion of the blood collection tube holder main body. While swinging toward the inner peripheral surface side of the blood collection tube holder body, it is pressed against the outer peripheral surface of the blood collection tube by its own elastic force. As a result, the blood collection tube holder holds the blood collection tube by the pressure contact member that presses against the outer peripheral surface of the blood collection tube while the collected blood sample is introduced into the blood collection tube, and the hollow of the blood collection tube holder body. It is possible to prevent the blood collection tube from falling off from the portion.

　しかしながら、特許文献１記載の採血管ホルダーは、前記採血管ホルダー本体の中空部に前記採血管を挿入すると、前記針管を被覆する弾性鞘体が該採血管の先端部に押圧されて圧縮され、それ自体の弾性により原状に復帰しようとするときに、該採血管が該弾性鞘体に押圧されて該採血管ホルダー本体から脱落する虞があるという不都合がある。 However, in the blood collection tube holder described in Patent Document 1, when the blood collection tube is inserted into the hollow portion of the blood collection tube holder main body, the elastic sheath covering the needle tube is pressed against the tip of the blood collection tube and compressed. There is a disadvantage that the blood collection tube may be pressed by the elastic sheath and fall off from the blood collection tube holder body when trying to return to the original state due to its own elasticity.
　本発明は、かかる不都合を解消して、圧縮された前記弾性鞘体に押圧されたときにも前記採血管が脱落することのない採血管ホルダーを提供することを目的とする。 An object of the present invention is to eliminate such inconvenience and provide a blood collection tube holder in which the blood collection tube does not fall off even when pressed by the compressed elastic sheath body.
　かかる目的を達成するために、本発明の採血管ホルダーは、中空有底筒状の採血管ホルダー本体と、該採血管ホルダー本体の内周面に内嵌されて該採血管ホルダー本体の中空部に挿入される採血管を着脱自在に保持する保持部材とを備え、該採血管ホルダー本体は、底部に設けられた針基と、該針基に支持されて該採血管ホルダー本体の中空部に突出する中空の針管と、該針管をその全長に亘って被覆する弾性鞘体とを備え、該保持部材は、該採血管ホルダー本体の内周面に内嵌される中空筒状の嵌合部材と、該嵌合部材から該採血管ホルダー本体の中空部に突出し、該採血管ホルダー本体の中空部に該採血管が挿入されたときに該採血管ホルダー本体の内周面側に揺動する一方、それ自体の弾性力により該採血管の外周面に圧接する複数の圧接部材とを備える採血管ホルダーにおいて、該圧接部材は、該嵌合部材から該採血管ホルダー本体の中空部の中心軸側に突出する腕状部と、該腕状部の先端部から該採血管ホルダー本体の内周面側に屈曲する屈曲部と、該嵌合部材と該腕状部を接続する第１の補強片及び該腕状部と該屈曲部を接続する第２の補強片の少なくともいずれか一方とを備えることを特徴とする。 In order to achieve such an object, the blood collection tube holder of the present invention is fitted into a hollow bottomed tubular body collection tube holder body and an inner peripheral surface of the blood collection tube holder body, and is a hollow portion of the blood collection tube holder body. A holding member for detachably holding the blood collection tube to be inserted into the blood collection tube holder body is provided in a needle base provided at the bottom and a hollow portion of the blood collection tube holder body supported by the needle base. A hollow tubular fitting member provided with a protruding hollow needle tube and an elastic sheath body that covers the needle tube over its entire length, and the holding member is internally fitted on the inner peripheral surface of the blood collection tube holder body. Then, it protrudes from the fitting member into the hollow portion of the blood collection tube holder body, and swings toward the inner peripheral surface side of the blood collection tube holder body when the blood collection tube is inserted into the hollow portion of the blood collection tube holder body. On the other hand, in a blood collection tube holder including a plurality of pressure contact members that are pressed against the outer peripheral surface of the blood collection tube by its own elastic force, the pressure contact member is a central axis of a hollow portion of the blood collection tube holder main body from the fitting member.

　本実施形態の採血管ホルダー１では、針基１５のオスコネクタ１５ａがメスコネクタ５３に嵌合されることにより採血具５と接続された状態で、例えば、図３に示すように、採血管ホルダー本体１１に内嵌された保持部材１２の内周側に、真空採血管３ａを挿入する。ここで、真空採血管３ａは、オーバーキャップタイプであり、ガラス、硬質プラスチック等からなる中空有底筒状体からなる採血管本体３１と、採血管本体３１の開口端部を閉塞するゴムキャップ３２と、採血管本体３１及びゴムキャップ３２を保護する中空有底筒状体からなる合成樹脂製の外筒管（オーバーキャップ）３３とからなる。外筒管３３はゴムキャップ３２に外嵌される一方、底部にゴムキャップ３２の一部を露出する開口部を備えている。 In the blood collection tube holder 1 of the present embodiment, the male connector 15a of the needle base 15 is fitted to the female connector 53 to be connected to the blood collection tool 5, for example, as shown in FIG. The vacuum blood collection tube 3a is inserted into the inner peripheral side of the holding member 12 fitted in the main body 11. Here, the vacuum blood collection tube 3a is an overcap type, and is a blood collection tube body 31 made of a hollow bottomed tubular body made of glass, hard plastic, or the like, and a rubber cap 32 that closes the open end of the blood collection tube body 31. And an outer tube (overcap) 33 made of synthetic resin made of a hollow bottomed tubular body that protects the blood collection tube main body 31 and the rubber cap 32. The outer tube 33 is fitted onto the rubber cap 32, and has an opening at the bottom that exposes a part of the rubber cap 32.
　保持部材１２の内周側に、真空採血管３ａを挿入すると、嵌合部材２１から採血管ホルダー本体１１の中空部１６に突出する圧接部材２２が真空採血管３ａに押圧されて、図３に仮想線示する状態から採血管ホルダー本体１１の内周面側に揺動変形する。このとき、圧接部材２２の腕状部２３と屈曲部２４とは、真空採血管３ａによる押圧の結果断面視略直線状となっており、それ自体の弾性力により原状（図３に仮想線示する状態）に復帰しようとし、真空採血管３ａの外周面に圧接される。 When the vacuum blood collection tube 3a is inserted into the inner peripheral side of the holding member 12, the pressure contact member 22 protruding from the fitting member 21 into the hollow portion 16 of the blood collection tube holder main body 11 is pressed against the vacuum blood collection tube 3a, and FIG. From the state shown by the virtual line, it swings and deforms toward the inner peripheral surface side of the blood collection tube holder main body 11. At this time, the arm-shaped portion 23 and the bent portion 24 of the pressure contact member 22 are substantially linear in cross section as a result of pressing by the vacuum collecting tube 3a, and are in their original state due to their own elastic force (virtual line shown in FIG. 3). It is pressed against the outer peripheral surface of the vacuum blood collection tube 3a in an attempt to return to the state of
　一方、保持部材１２の内周側に、真空採血管３ａを挿入すると、ゴムキャップ３２がゴムスリーブ１８に当接され、さらにゴムスリーブ１８を針基１５側に向けて押圧する。この結果、針管１７がゴムスリーブ１８及びゴムキャップ３２を貫通して、真空採血管３ａ内に挿入される一方、ゴムスリーブ１８は圧縮され、ゴムキャップ３２と針基１５との間で蛇腹状に折り畳まれた状態になる。 On the other hand, when the vacuum collecting blood vessel 3a is inserted into the inner peripheral side of the holding member 12, the rubber cap 32 is brought into contact with the rubber sleeve 18 and the rubber sleeve 18 is further pressed toward the needle base 15. As a result, the needle tube 17 penetrates the rubber sleeve 18 and the rubber cap 32 and is inserted into the vacuum collection tube 3a, while the rubber sleeve 18 is compressed and forms a bellows shape between the rubber cap 32 and the needle base 15. It will be in a folded state.
　針管１７が真空採血管３ａ内に挿入されると、針管１７は針基１５の中空部１９及び可撓性チューブ５２を介して採血針管５１に連通されているので、採血具５の採血針管５１により採血される血液試料が可撓性チューブ５２及び針管１７を介して真空採血管３ａ内に導入される。 When the needle tube 17 is inserted into the vacuum blood collection tube 3a, the needle tube 17 is communicated with the blood collection needle tube 51 via the hollow portion 19 of the needle base 15 and the flexible tube 52, so that the blood collection needle tube 51 of the blood collection tool 5 The blood sample collected by the blood sample is introduced into the vacuum blood collection tube 3a via the flexible tube 52 and the needle tube 17.
　このとき、前述のように圧縮され、ゴムキャップ３２と針基１５との間で蛇腹状に折り畳まれた状態となっているゴムスリーブ１８は、それ自体の弾性力により原状に復帰しようとして真空採血管３ａを開口側（嵌合部材２１側）に向けて押圧するので、圧接部材２２の圧接により保持されている真空採血管３ａが採血管ホルダー本体１１から脱落することが懸念される。 At this time, the rubber sleeve 18, which is compressed as described above and is folded in a bellows shape between the rubber cap 32 and the needle base 15, is vacuumed in an attempt to return to its original state by its own elastic force. Since the blood vessel 3a is pressed toward the opening side (fitting member 21 side), there is a concern that the vacuum blood collection tube 3a held by the pressure contact of the pressure contact member 22 may fall off from the blood collection tube holder main body 11.
　しかし、本実施形態の採血管ホルダー１では、前述のように真空採血管３ａによる押圧の結果、圧接部材２２の腕状部２３と屈曲部２４とが断面視略直線状となっており、屈曲部２４の先端が舌状突出片２０に接触することにより、舌状突出片２０を採血管ホルダー本体１１の内周面側に揺動変形させる。舌状突出片２０は、前記のように揺動されるとそれ自体の弾性力により原状に復帰しようとし、屈曲部２４の先端を前記採血管の外周面側に向けて押圧する。 However, in the blood collection tube holder 1 of the present embodiment, as a result of pressing by the vacuum collection tube 3a as described above, the arm-shaped portion 23 and the bent portion 24 of the pressure contact member 22 are substantially linear in cross section, and are bent. When the tip of the portion 24 comes into contact with the tongue-shaped protruding piece 20, the tongue-shaped protruding piece 20 is oscillated and deformed toward the inner peripheral surface side of the blood collection tube holder main body 11. When the tongue-shaped projecting piece 20 is swung as described above, it tries to return to its original state by its own elastic force, and presses the tip of the bent portion 24 toward the outer peripheral surface side of the blood collection tube.
　この結果、圧接部材２２は、それ自体の弾性力に加えて、舌状突出片２０の押圧力により真空採血管３ａの外周面に対する圧接が補助されることとなり、より強い力で真空採血管３ａを保持することができる。従って、真空採血管３ａが圧縮されたゴムスリーブ１８により開口側に向けて押圧されたときにも、採血管ホルダー本体１１から真空採血管３ａが脱落することを防止することができる。 As a result, the pressure contact member 22 is assisted in pressure contact with the outer peripheral surface of the vacuum collection tube 3a by the pressing force of the tongue-shaped protruding piece 20 in addition to its own elastic force, and the vacuum collection tube 3a has a stronger force. Can be retained. Therefore, even when the vacuum collection tube 3a is pressed toward the opening side by the compressed rubber sleeve 18, it is possible to prevent the vacuum collection tube 3a from falling off from the blood collection tube holder main body 11.
　本実施形態の採血管ホルダー１では、真空採血管３ａに所定量の血液試料が貯留されたならば、真空採血管３ａを抜去する。このとき、ゴムスリーブ１８は真空採血管３ａの抜去に伴って原状に復帰し、針管１７をその全長に亘って被覆するので、血液試料が針管１７から外部に漏出することを防止することができる。 In the blood collection tube holder 1 of the present embodiment, when a predetermined amount of blood sample is stored in the vacuum collection tube 3a, the vacuum collection tube 3a is removed. At this time, the rubber sleeve 18 returns to its original state with the removal of the vacuum collection tube 3a and covers the needle tube 17 over its entire length, so that it is possible to prevent the blood sample from leaking from the needle tube 17 to the outside. ..
　また、本実施形態の採血管ホルダー１では、針基１５のオスコネクタ１５ａがメスコネクタ５３に嵌合されることにより採血具５と接続された状態で、例えば、図４に示すように、採血管ホルダー本体１１に内嵌された保持部材１２の内周側に、真空採血管３ｂを挿入するようにしてもよい。ここで、真空採血管３ｂは、ゴム栓キャップタイプであり、ガラス、硬質プラスチック等からなる中空有底筒状体からなる採血管本体３１と、採血管本体３１の開口端部を閉塞するゴムキャップ３２とを備えている。 Further, in the blood collection tube holder 1 of the present embodiment, the male connector 15a of the needle base 15 is fitted to the female connector 53 and connected to the blood collection tool 5, for example, as shown in FIG. The vacuum collecting blood vessel 3b may be inserted into the inner peripheral side of the holding member 12 fitted in the blood vessel holder main body 11. Here, the vacuum blood collection tube 3b is a rubber stopper cap type, and is a rubber cap that closes the blood collection tube body 31 made of a hollow bottomed tubular body made of glass, hard plastic, or the like, and the open end portion of the blood collection tube body 31. It has 32 and.
　本実施形態の採血管ホルダー１は、ゴム栓キャップタイプの真空採血管３ｂに対しても、オーバーキャップタイプの真空採血管３ａの場合と同様にして、真空採血管３ｂが圧縮されたゴムスリーブ１８により後方に押圧されたときにも、採血管ホルダー本体１１から真空採血管３ｂが脱落することを防止することができる。 In the blood collection tube holder 1 of the present embodiment, the rubber sleeve 18 in which the vacuum collection tube 3b is compressed is the same as in the case of the overcap type vacuum collection tube 3a, even for the vacuum collection tube 3b of the rubber stopper cap type. It is possible to prevent the vacuum blood collection tube 3b from falling off from the blood collection tube holder main body 11 even when the vacuum collection tube 3b is pressed backward.
　さらに、本実施形態の採血管ホルダー１では、針基１５のオスコネクタ１５ａがメスコネクタ５３に嵌合されることにより採血具５と接続された状態で、例えば、図５に示すように、採血管ホルダー本体１１に内嵌された保持部材１２の内周側に、真空採血管３ｃを挿入するようにしてもよい。ここで、真空採血管３ｃは、シールタイプであり、ガラス、硬質プラスチック等からなる中空有底筒状体からなる採血管本体３１と、採血管本体３１の開口端部を閉塞するシール部材３４とを備えている。シール部材３４は例えばアルミフィルムからなるシートの中央部にゴム製の弁体３５を備えて構成されている。また、採血管本体３１は開口端部から外方に延出するフランジ状のフランジ状部３６を備えている。なお、フランジ状部３６は、採血管本体３１に固定された別部材から構成される場合もある。 Further, in the blood collection tube holder 1 of the present embodiment, the male connector 15a of the needle base 15 is fitted to the female connector 53 to be connected to the blood collection tool 5, for example, as shown in FIG. The vacuum collecting blood vessel 3c may be inserted into the inner peripheral side of the holding member 12 fitted in the blood vessel holder main body 11. Here, the vacuum blood collection tube 3c is a seal type, and includes a blood collection tube body 31 made of a hollow bottomed tubular body made of glass, hard plastic, or the like, and a seal member 34 that closes the opening end of the blood collection tube body 31. It has. The seal member 34 is configured to include, for example, a rubber valve body 35 at the center of a sheet made of an aluminum film. Further, the blood collection tube main body 31 is provided with a flange-shaped flange-shaped portion 36 extending outward from the open end portion. The flange-shaped portion 36 may be composed of another member fixed to the blood collection tube main body 31.
　本実施形態の採血管ホルダー１は、シールタイプの真空採血管３ｃに対しても、オーバーキャップタイプの真空採血管３ａ及びゴム栓キャップタイプの真空採血管３ｂの場合と同様にして、真空採血管３ｃが圧縮されたゴムスリーブ１８により後方に押圧されたときにも、採血管ホルダー本体１１から真空採血管３ｃが脱落することを防止することができる。また、シールタイプの真空採血管３ｃはフランジ状部３６を備えるので、フランジ状部３６を屈曲部２４の係止部２７に係止することができ、さらに確実に採血管ホルダー本体１１から真空採血管３ｃが脱落することを防止することができる。 The blood collection tube holder 1 of the present embodiment also applies to the seal type vacuum collection tube 3c in the same manner as in the case of the overcap type vacuum collection tube 3a and the rubber stopper cap type vacuum collection tube 3b. Even when the 3c is pressed backward by the compressed rubber sleeve 18, it is possible to prevent the vacuum blood collection tube 3c from falling off from the blood collection tube holder main body 11. Further, since the seal type vacuum collecting blood vessel 3c includes the flange-shaped portion 36, the flange-shaped portion 36 can be locked to the locking portion 27 of the bent portion 24, and the vacuum collecting tube holder main body 11 can be more reliably vacuum-collected. It is possible to prevent the blood vessel 3c from falling off.
　本実施形態では、採血管ホルダー本体１１に舌状突出片２０を設けることで、保持部材１２全体の厚みやサイズを大きくすることなく適切な保持力を発生させることを可能としている。この結果、真空採血管３ａ，３ｂ，３ｃの脱落を確実に防止しながらも、採血管ホルダー本体１１をコンパクトに構成することが可能となるため、真空採血管３ａの挿抜性及び採血管ホルダー本体１１の把持性が阻害されないようになっている。 In the present embodiment, by providing the tongue-shaped protruding piece 20 on the blood collection tube holder main body 11, it is possible to generate an appropriate holding force without increasing the thickness and size of the entire holding member 12. As a result, the vacuum collecting blood collection tube 3a, 3b, and 3c can be reliably prevented from falling off, and the blood collection tube holder main body 11 can be compactly configured. The grip of 11 is not hindered.
　また、本実施形態では、屈曲部２４は真空採血管３ａ，３ｂ，３ｃの挿入がある程度進んだ後に舌状突出片２０と接触し、それ以前は挿入抵抗となる弾性力が保持部材１２の弾性力のみとなっているため、真空採血管３ａ，３ｂ，３ｃの脱落を確実に防止しながらも、真空採血管３ａ，３ｂ，３ｃを容易に挿入することが可能となっている。 Further, in the present embodiment, the bent portion 24 comes into contact with the tongue-shaped protruding piece 20 after the insertion of the vacuum collecting tubes 3a, 3b, and 3c has progressed to some extent, and before that, the elastic force that becomes the insertion resistance is the elasticity of the holding member 12. Since it is only a force, it is possible to easily insert the vacuum collection tubes 3a, 3b, 3c while surely preventing the vacuum collection tubes 3a, 3b, 3c from falling off.
　さらに、本実施形態では、真空採血管３ａ，３ｂ，３ｃの挿入によって押し開かれるように変形する曲折部分に第１の補強片２５及び第２の補強片２６を設けることで、適切な保持力を発生させながらも、保持部材１２をよりコンパクトに構成することが可能となっている。また、保持部材１２に係止部２７を設けることで、フランジ状部３６以外の部分が比較的小径であることから採血管ホルダー本体１１に対して傾きやすいシールタイプの真空採血管３ｃであっても、安定的に保持して脱落を防止することが可能となっている。 Further, in the present embodiment, an appropriate holding force is provided by providing the first reinforcing piece 25 and the second reinforcing piece 26 in the bent portion that is deformed so as to be pushed open by inserting the vacuum collecting tubes 3a, 3b, and 3c. It is possible to make the holding member 12 more compact while generating the above. Further, by providing the locking portion 27 on the holding member 12, the portion other than the flange-shaped portion 36 has a relatively small diameter, so that the vacuum collecting blood vessel 3c is a seal type that easily tilts with respect to the blood collection tube holder main body 11. However, it is possible to hold it stably and prevent it from falling off.
　また、本実施形態では、屈曲部２４の外側面の先端側に傾斜面２４ａを設けると共に、この傾斜面２４ａの先端に丸みを設けることで、舌状突出片２０との接触、並びに接触後の保持部材１２及び舌状突出片２０の変形がスムーズに行われるようにしている。また、腕状部２３及び屈曲部２４の内側面の幅方向両端に丸みを設けることで、真空採血管３ａ，３ｂ，３ｃの外周面に貼付されたラベル等が腕状部２３又は屈曲部２４に引っ掛かって剥がれたり破損したりするのを防止している。 Further, in the present embodiment, the inclined surface 24a is provided on the tip end side of the outer surface of the bent portion 24, and the tip of the inclined surface 24a is rounded so that the tongue-shaped projecting piece 20 can be contacted and after the contact. The holding member 12 and the tongue-shaped protruding piece 20 are smoothly deformed. Further, by providing roundness at both ends of the inner side surface of the arm-shaped portion 23 and the bent portion 24 in the width direction, a label or the like attached to the outer peripheral surfaces of the vacuum collecting tubes 3a, 3b, 3c can be attached to the arm-shaped portion 23 or the bent portion 24. It prevents it from being caught in the vacuum and peeling off or being damaged.
　なお、舌状突出片２０は、真空採血管３ａ，３ｂ，３ｃの挿入によって揺動変形した場合に先端部が採血管ホルダー本体１１の内周面に接触するように構成されるものであってもよいし、接触しないように構成されるものであってもよい。同様に、圧接部材２２は、真空採血管３ａ，３ｂ，３ｃの挿入によって揺動変形した場合にいずれかの部分が採血管ホルダー本体１１の内周面に接触するように構成されるものであってもよいし、接触しないように構成されるものであってもよい。 The tongue-shaped protruding piece 20 is configured such that the tip end portion comes into contact with the inner peripheral surface of the blood collection tube holder main body 11 when the vacuum collection tube 3a, 3b, 3c is oscillated and deformed. It may be configured so as not to come into contact with each other. Similarly, the pressure contact member 22 is configured such that any part of the pressure contact member 22 comes into contact with the inner peripheral surface of the blood collection tube holder main body 11 when the vacuum collection tubes 3a, 3b, and 3c are oscillated and deformed. It may be configured so as not to come into contact with each other.
　また、採血管ホルダー１は、採血管ホルダー本体１１の内周面に、長さ方向（軸方向）に延在して真空採血管３ａ，３ｂ，３ｃの外周面に当接する例えばリブ状の当接部（図示せず）を備えていてもよい。また、採血管ホルダー１は、採血管ホルダー本体１１の内周面に、長さ方向に延在して揺動変形された圧接部材２２を収容する（干渉を避ける）例えば溝状の凹部（図示せず）を備えていてもよい。 Further, the blood collection tube holder 1 extends in the length direction (axial direction) on the inner peripheral surface of the blood collection tube holder main body 11, and abuts on the outer peripheral surfaces of the vacuum blood collection tubes 3a, 3b, 3c, for example, in a rib shape. It may be provided with a contact portion (not shown). Further, the blood collection tube holder 1 accommodates a pressure contact member 22 extending in the length direction and deformed by swinging on the inner peripheral surface of the blood collection tube holder main body 11 (to avoid interference), for example, a groove-shaped recess (FIG. (Not shown) may be provided.
　このような当接部を備えることで、真空採血管３ａ，３ｂ，３ｃが採血管ホルダー本体１１に対して傾くのを防止し、針管１７を真空採血管３ａ，３ｂ，３ｃに適切に貫通させると共に、真空採血管３ａ，３ｂ，３ｃを安定的に保持することが可能となる。また、このような凹部を備えることで、保持部材１２を設けることによる真空採血管３ａ，３ｂ，３ｃの確実な保持を可能としながらも、採血管ホルダー本体１１の外径を小さくして把持性を及び操作性を向上させることができる。なお、このような凹部を設ける場合においても、揺動変形された舌状突出片２０又は圧接部材２２を凹部の底面に接触させるようにしてもよいし、接触させないようにしてもよい。 By providing such a contact portion, the vacuum collection tubes 3a, 3b, 3c are prevented from tilting with respect to the vacuum collection tube holder main body 11, and the needle tube 17 is appropriately penetrated through the vacuum collection tubes 3a, 3b, 3c. At the same time, the vacuum collection tubes 3a, 3b, and 3c can be stably held. Further, by providing such a recess, the vacuum collecting blood vessels 3a, 3b, and 3c can be reliably held by providing the holding member 12, but the outer diameter of the blood collection tube holder main body 11 is reduced for gripability. And operability can be improved. Even when such a recess is provided, the tongue-shaped protruding piece 20 or the pressure contact member 22 that has been oscillated and deformed may or may not be brought into contact with the bottom surface of the recess.
　また、圧接部材２２及び舌状突出片２０の個数は、特に限定されるものではなく、任意の個数を採用することができる。また、舌状突出片２０は、採血管ホルダー本体１１の内周面から突出するものであってもよいし、採血管ホルダー本体１１に固定される別部材から構成されるものであってもよい。また、舌状突出片２０によって十分な保持力が得られるような場合には、保持部材１２において、第１の補強片２５、第２の補強片２６、又は係止部２７を省略するようにしてもよい。 Further, the number of the pressure contact member 22 and the tongue-shaped protruding piece 20 is not particularly limited, and any number can be adopted. Further, the tongue-shaped protruding piece 20 may be one that protrudes from the inner peripheral surface of the blood collection tube holder main body 11, or may be composed of another member fixed to the blood collection tube holder main body 11. .. Further, when a sufficient holding force can be obtained by the tongue-shaped protruding piece 20, the first reinforcing piece 25, the second reinforcing piece 26, or the locking portion 27 is omitted in the holding member 12. You may.
　また、針基１５は、突出部１４と一体的に構成されるものであってもよい。また、オスコネクタ１５ａは、針基１５とは別個に突出部１４に設けられるものであってもよい。また、オスコネクタ１５ａは、雌ネジが設けられたロック部材を備えるものであってもよい。また、オスコネクタ１５ａに代えて、血管に穿刺される採血針管を針基１５に設けるようにしてもよい。 Further, the needle base 15 may be integrally formed with the protruding portion 14. Further, the male connector 15a may be provided on the protruding portion 14 separately from the needle base 15. Further, the male connector 15a may include a lock member provided with a female screw. Further, instead of the male connector 15a, a blood collection needle tube to be punctured into a blood vessel may be provided in the needle base 15.
　また、採血キット２において、採血具５は、翼状針以外のものであってもよく、可撓性チューブ５２を介さずに採血管ホルダー本体１１に接続されるものであってもよい。また、採血具５は、可撓性チューブ５２を備えず、適宜のコネクタを備えるエクステンションチューブを介して採血管ホルダー本体１１に接続されるものであってもよい。 Further, in the blood collection kit 2, the blood collection tool 5 may be something other than a winged needle, or may be connected to the blood collection tube holder main body 11 without passing through the flexible tube 52. Further, the blood collection tool 5 may be connected to the blood collection tube holder main body 11 via an extension tube provided with an appropriate connector without providing the flexible tube 52.
　また、採血管ホルダー本体１１における針管１７及びゴムスリーブ１８以外の部分の材質は、ポリプロピレン以外にも、例えばポリカーボネート、ポリスチレン、アクリルニトリルブタジエンスチレン（ＡＢＳ樹脂）、ポリエチレンテレフタレート、ポリ塩化ビニル、又はポリメタクリル酸メチル樹脂（アクリル樹脂）等を採用することが可能であり、保持部材１２についても同様である。また、ゴムスリーブ１８の材質は、イソプレンゴム以外にも、例えばシリコーンゴム、ブタジエンゴム、ブチルゴム、天然ゴム、ウレタンゴム、又はフッ素ゴム等を採用することができる。 In addition to polypropylene, the material of the portion of the blood collection tube holder body 11 other than the needle tube 17 and the rubber sleeve 18 is, for example, polycarbonate, polystyrene, acrylicnitrile butadiene styrene (ABS resin), polyethylene terephthalate, polyvinyl chloride, or polymethacryl. It is possible to use methyl acid acid resin (acrylic resin) or the like, and the same applies to the holding member 12.

In FIG. 7, the description of the needle base 15, the needle tube 17, and the rubber sleeve 18 is omitted. As shown in FIG. 7, the first contact portion 11d and the second contact portion 11e project toward the central axis side on the inner peripheral surface of the blood collection tube holder main body 11, and from the bottom portion 13 to the opening side. It is configured in a rib shape that is continuous (extending) in the axial direction. Further, the first contact portion 11d and the second contact portion 11e are arranged at four positions in the circumferential direction of the blood collection tube holder main body 11 and are arranged alternately in the circumferential direction.
　第１の当接部１１ｄは、底部１３側が突出量の大きい段付き形状に構成され、中間部分に段差部１１ｄ１が設けられている。また、第１の当接部１１ｄの開口側の端部には、開口側に向けて漸次突出量が減少して内周面に繋がる傾斜部１１ｄ２が設けられている。同様に、第２の当接部１１ｅは、底部１３側が突出量の大きい段付き形状に構成され、中間部分に段差部１１ｅ１が設けられている。そして、第２の当接部１１ｅの開口側の端部には、真空採血管３ｃのフランジ状部３６に係止する係止部１１ｆが設けられている。 The first contact portion 11d has a stepped shape with a large protrusion amount on the bottom 13 side, and a step portion 11d1 is provided in the intermediate portion.

　第１の当接部１１ｄ及び第２の当接部１１ｅの軸方向の長さは、特に限定されるものではないが、この例では、採血管ホルダー本体１１の中空部１６の軸方向の長さの凡そ１／３に設定している。 The axial lengths of the first contact portion 11d and the second contact portion 11e are not particularly limited, but in this example, the axial length of the hollow portion 16 of the blood collection tube holder main body 11. It is set to about 1/3 of the size.
　また、この例では、真空採血管３ａ，３ｂの先端面に当接することで真空採血管３ａ，３ｂを軸方向に位置決めする第３当接部１１ｇを、底部１３の内側面の４箇所に設けている。この第３当接部１１ｇは、開口側に向けて突出し、開口側から見た場合に中空部１６の中心軸を中心とする４つの円弧状の突起から構成されている。このような第３当接部１１ｇを設けることで、真空採血管３ａ，３ｂを軸方向の適切な位置に配置する共に、針管１７の貫通後の真空採血管の３ａ，３ｂの傾きを抑制することができる。 Further, in this example, third contact portions 11g for axially positioning the vacuum collection tubes 3a and 3b by contacting the tip surfaces of the vacuum collection tubes 3a and 3b are provided at four locations on the inner surface of the bottom portion 13. ing. The third contact portion 11g protrudes toward the opening side and is composed of four arc-shaped protrusions centered on the central axis of the hollow portion 16 when viewed from the opening side. By providing such a third contact portion 11g, the vacuum collection tubes 3a and 3b are arranged at appropriate positions in the axial direction, and the inclination of the vacuum collection tubes 3a and 3b after penetrating the needle tube 17 is suppressed. be able to.
　さらに、この例では、保持部材１２の嵌合部材２１の台形状部２１ａ以外の部分を収容する第１の凹部１１ｈと、嵌合部材２１の台形状部２１ａを収容すると共に、揺動した圧接部材２２及び舌状突出片２０の少なくとも一部を収容する（干渉を避ける）ための第２の凹部１１ｉとを採血管ホルダー本体１１の内周面に設けている。上述のように、このような第１の凹部１１ｈ及び第２の凹部１１ｉを設けることで、採血管ホルダー本体１１の外径を小径化して把持性及び操作性を向上させることができる。また、第１の凹部１１ｈ又は第２の凹部１１ｉを設けることで、保持部材１２の厚みや形状の設計の自由度が高くなるため、圧接部材２２の弾性力を従来よりも大きくし、十分な保持力を発生させることができる。 Further, in this example, the first recess 11h for accommodating a portion other than the trapezoidal portion 21a of the fitting member 21 of the holding member 12 and the trapezoidal portion 21a of the fitting member 21 are accommodated and oscillated pressure welding. A second recess 11i for accommodating (avoiding interference) at least a part of the member 22 and the tongue-shaped projecting piece 20 is provided on the inner peripheral surface of the blood collection tube holder main body 11. As described above, by providing the first recess 11h and the second recess 11i, the outer diameter of the blood collection tube holder main body 11 can be reduced to improve grip and operability. Further, by providing the first recess 11h or the second recess 11i, the degree of freedom in designing the thickness and shape of the holding member 12 is increased, so that the elastic force of the pressure welding member 22 is made larger than before, which is sufficient. A holding force can be generated.
　第１の凹部１１ｈは、採血管ホルダー本体１１の内周面の開口側端部において周方向に連続する（延在する）溝状に構成されている。そして、第１の凹部１１ｈの底面には、保持部材１２の位置決め突起２１ｃを収容する位置決め凹部１１ｈ１と、保持部材１２の抜け止め突起２１ｃを収容する抜け止め凹部１１ｈ２とが、それぞれ対応する位置に設けられている。 The first recess 11h is formed in a groove shape that is continuous (extending) in the circumferential direction at the opening side end of the inner peripheral surface of the blood collection tube holder main body 11. Then, on the bottom surface of the first recess 11h, the positioning recess 11h1 accommodating the positioning protrusion 21c of the holding member 12 and the retaining recess 11h2 accommodating the retaining protrusion 21c of the holding member 12 are located at corresponding positions. It is provided.
　第２の凹部１１ｉは、採血管ホルダー本体１１の内周面の圧接部材２２に対応する位置において第１の凹部１１ｈから底部１３側に向けて軸方向に延在する溝状に構成されている。第２の凹部１１ｉをこのように構成することで、真空採血管３ａ，３ｂ，３ｃの挿入に伴う揺動の際に大きなモーメントが加わる腕状部２３およびこれを支持する嵌合部材２１の設計の自由度がより高まるため、圧接部材２２の弾性力をより大きくして真空採血管３ａ，３ｂ，３ｃの脱落をより確実に防止することができる。また、第２の凹部１１ｉの底面の底部１３側には、舌状突出片２０に対応して深さを増加させた追加凹部１１ｉ１が設けられている。 The second recess 11i is formed in a groove shape extending axially from the first recess 11h toward the bottom 13 side at a position corresponding to the pressure contact member 22 on the inner peripheral surface of the blood collection tube holder main body 11. .. By configuring the second recess 11i in this way, the design of the arm-shaped portion 23 to which a large moment is applied when swinging due to the insertion of the vacuum collecting tubes 3a, 3b, 3c and the fitting member 21 supporting the arm-shaped portion 23 Since the degree of freedom of the pressure contact member 22 is further increased, the elastic force of the pressure contact member 22 can be further increased to more reliably prevent the vacuum collection tubes 3a, 3b, and 3c from falling off. Further, on the bottom 13 side of the bottom surface of the second recess 11i, an additional recess 11i1 having an increased depth corresponding to the tongue-shaped protruding piece 20 is provided.
　第１の凹部１１ｈ及び第２の凹部１１ｉの深さは、特に限定されるものではないが、採血管ホルダー本体１１の内周面と嵌合部材２１の内周面との間に生じる段差が小さい方が好ましく、内周面と嵌合部材２１の内周面が面一となる深さであることがより好ましい。 The depths of the first recess 11h and the second recess 11i are not particularly limited, but there is a step generated between the inner peripheral surface of the blood collection tube holder main body 11 and the inner peripheral surface of the fitting member 21. The smaller the value is preferable, and the depth is more preferably such that the inner peripheral surface and the inner peripheral surface of the fitting member 21 are flush with each other.
　採血管ホルダー本体１１の内周面と嵌合部材２１の内周面を面一にすることで、真空採血管３ａ，３ｂ，３ｃの挿抜時にこれらの外周面に貼付されたラベルやシールタイプの真空採血管３ｃのシール部材３４が段差に引っ掛かって剥がれたり破損したりするのを防止することができる。 By making the inner peripheral surface of the blood collection tube holder main body 11 and the inner peripheral surface of the fitting member 21 flush with each other, the label or seal type attached to the outer peripheral surfaces of the vacuum blood collection tubes 3a, 3b, 3c can be used. It is possible to prevent the seal member 34 of the vacuum collection tube 3c from being caught in the step and being peeled off or damaged.
　なお、第１の凹部１１ｈ及び第２の凹部１１ｉのいずれか一方のみを設けるようにしてもよい。また、第１の凹部１１ｈとして、位置決め凹部１１ｈ１及び抜け止め凹部１１ｈ２のみを設けるようにしてもよい。また、第２の凹部１１ｉにおいて、追加凹部１１ｉ１を省略するようにしてもよい。 Note that only one of the first recess 11h and the second recess 11i may be provided. Further, as the first recess 11h, only the positioning recess 11h1 and the retaining recess 11h2 may be provided. Further, in the second recess 11i, the additional recess 11i1 may be omitted.
　この例ではまた、舌状突出片２０の内側面の突端側に突端に向けて漸次厚みが減少する傾斜面２０ａを設けると共に、この傾斜面２０ａの先端の角部に適宜の丸みを設けることで、保持部材１２との接触、並びに接触後の保持部材１２及び舌状突出片２０の変形がよりスムーズに行われるようにしている。 In this example, the tongue-shaped projecting piece 20 is provided with an inclined surface 20a whose thickness gradually decreases toward the tip on the tip side of the inner surface, and an appropriate roundness is provided at the corner of the tip of the inclined surface 20a. , The contact with the holding member 12, and the deformation of the holding member 12 and the tongue-shaped projecting piece 20 after the contact are made smoother.
　また、採血管ホルダー本体１１の突出部１４には、針基１５の雄ネジと螺合する２条の雌ネジ１４ａが設けられているが、この例では２つのネジ山を互いに軸方向において重ならないように設けることで、樹脂成形の金型の構造を簡素化することを可能としている。 Further, the protruding portion 14 of the blood collection tube holder main body 11 is provided with two female screws 14a screwed with the male screw of the needle base 15, but in this example, the two threads overlap each other in the axial direction. It is possible to simplify the structure of the resin molding mold by providing it so that it does not become.
　図８は、図６に示す例における保持部材１２の外観図である。上述のように、この例では、係止部２７は省略されている。また、この例では、位置決め突起２１ｂを周方向の４箇所に設けることで、採血管ホルダー本体１１への保持部材１２の組付けを容易にしている。さらに、この例では、第２の補強片２６によって適切な保持力を維持しつつ、第１の補強片２５を省略することで、真空採血管３ａ，３ｂ，３ｃの挿入開始時の挿入抵抗を軽減するようにしている。 FIG. 8 is an external view of the holding member 12 in the example shown in FIG. As described above, in this example, the locking portion 27 is omitted. Further, in this example, by providing the positioning protrusions 21b at four positions in the circumferential direction, the holding member 12 can be easily assembled to the blood collection tube holder main body 11. Further, in this example, the insertion resistance at the start of insertion of the vacuum collection tubes 3a, 3b, 3c is reduced by omitting the first reinforcing piece 25 while maintaining an appropriate holding force by the second reinforcing piece 26. I try to reduce it.
　このように、第１の補強片２５及び第２の補強片２６は、いずれか一方のみが設けられるものであってもよく、このようにすることで、保持部材１２による保持力を適宜に調整することができる。なお、圧接部材２２毎に第１の補強片２５及び第２の補強片２６の設け方を異ならせるようにしてもよいし、第１の補強片２５及び第２の補強片２６を共に省略するようにしてもよい。 As described above, only one of the first reinforcing piece 25 and the second reinforcing piece 26 may be provided, and by doing so, the holding force by the holding member 12 is appropriately adjusted. can do. The method of providing the first reinforcing piece 25 and the second reinforcing piece 26 may be different for each pressure welding member 22, or both the first reinforcing piece 25 and the second reinforcing piece 26 may be omitted. You may do so.
　図９Ａは第１の当接部１１ｄを拡大して示す説明的断面図であり、図９Ｂは第２の当接部１１ｅを拡大して示す説明的断面図である。図９Ａに仮想線示するように、真空採血管３ｃは、フランジ状部３６の先端面が段差部１１ｄ１に当接することで軸方向に位置決めされる。また、フランジ状部３６の外周面が開口側の低い方の頂面１１ｄ３に当接することで、真空採血管３ｃは半径方向に位置決めされると共に採血管ホルダー本体１１に対する傾きが防止される。また、真空採血管３ｃは、挿入時に傾いていた場合にも傾斜部１１ｄ２によってフランジ状部３６の外周面が頂面１１ｄ３に当接する状態に誘導されるようになっている。 FIG. 9A is an enlarged explanatory cross-sectional view showing the first contact portion 11d, and FIG. 9B is an enlarged explanatory cross-sectional view showing the second contact portion 11e. As shown by a virtual line in FIG. 9A, the vacuum collection tube 3c is positioned in the axial direction when the tip surface of the flange-shaped portion 36 abuts on the step portion 11d1. Further, when the outer peripheral surface of the flange-shaped portion 36 abuts on the lower apex surface 11d3 on the opening side, the vacuum blood collection tube 3c is positioned in the radial direction and the inclination with respect to the blood collection tube holder main body 11 is prevented. Further, even when the vacuum collecting blood vessel 3c is tilted at the time of insertion, the tilted portion 11d2 guides the outer peripheral surface of the flange-shaped portion 36 to abut the top surface 11d3.
　図９Ｂに仮想線示するように、真空採血管３ｃは、第２の当接部１１ｅにおいても同様に、フランジ状部３６の先端面が段差部１１ｅ１に当接することで軸方向に位置決めされ、フランジ状部３６の外周面が開口側の低い方の頂面１１ｅ３に当接することで、半径方向の位置決め及び採血管ホルダー本体１１に対する傾き防止がなされる。そして、係止部１１ｆがフランジ状部３６に係止することによって、真空採血管３ｃの脱落が防止される。 As shown by a virtual line in FIG. 9B, the vacuum blood collection tube 3c is similarly positioned in the axial direction by the tip surface of the flange-shaped portion 36 abutting on the stepped portion 11e1 in the second contact portion 11e. When the outer peripheral surface of the flange-shaped portion 36 comes into contact with the lower top surface 11e3 on the opening side, radial positioning and tilt prevention with respect to the blood collection tube holder main body 11 are performed. Then, by locking the locking portion 11f to the flange-shaped portion 36, the vacuum collecting blood vessel 3c is prevented from falling off.
　この例では、係止部１１ｆを、頂面１１ｅ３からさらに突出するように設けている。また、係止部１１ｆを、中心軸と略平行となるように頂部に設けられた平行面１１ｆ１と、平行面１１ｆ１の開口側において開口側に向けて漸次突出量が減少する開口側傾斜面１１ｆ２と、平行面１１ｆ１の底部１３側において底部１３側に向けて漸次突出量が減少する底部側傾斜面１１ｆ３とを有する台形状に構成している。なお、開口側傾斜面１１ｆ２は、内周面と繋がるように設けられており、第１の当接部１１ｄの傾斜部１１ｄ２と同様の機能を奏する。 In this example, the locking portion 11f is provided so as to further protrude from the top surface 11e3. Further, the locking portion 11f is provided on the top of the parallel surface 11f1 so as to be substantially parallel to the central axis, and the opening side inclined surface 11f2 in which the amount of protrusion gradually decreases toward the opening side on the opening side of the parallel surface 11f1. And, on the bottom 13 side of the parallel surface 11f1, it is configured in a trapezoidal shape having a bottom side inclined surface 11f3 in which the amount of protrusion gradually decreases toward the bottom 13 side. The opening-side inclined surface 11f2 is provided so as to be connected to the inner peripheral surface, and has the same function as the inclined portion 11d2 of the first contact portion 11d.
　真空採血管３ｃの挿入時には、採血管ホルダー本体１１及びフランジ状部３６を弾性変形させることによって、フランジ状部３６に係止部１１ｆを乗り越えさせる必要がある。従って、挿入抵抗は、フランジ状部３６の先端側（底部１３側）の角部３６ａが開口側傾斜面１１ｆ２に当接している際に増加し、フランジ状部３６の基端側（開口側）の角部３６ｂが底部側傾斜面１１ｆ３に当接している際に減少することとなる。そして、使用者は、この挿入抵抗の増加からの減少をクリック感として感じることで、真空採血管３ｃが適切な位置に配置されたことを指先の感覚だけで把握することができる。 When inserting the vacuum blood collection tube 3c, it is necessary to elastically deform the blood collection tube holder main body 11 and the flange-shaped portion 36 so that the flange-shaped portion 36 gets over the locking portion 11f. Therefore, the insertion resistance increases when the corner portion 36a on the tip end side (bottom portion 13 side) of the flange-shaped portion 36 is in contact with the opening side inclined surface 11f2, and the base end side (opening side) of the flange-shaped portion 36. 36b is reduced when it is in contact with the bottom inclined surface 11f3. Then, the user can grasp that the vacuum collection tube 3c is arranged at an appropriate position only by the sensation of the fingertip by feeling the decrease from the increase in the insertion resistance as a click feeling.
　この例では、開口側傾斜面１１ｆ２と底部側傾斜面１１ｆ３の間に平行面１１ｆ１を設けることで、このクリック感を適切に生じさせるようにしている。具体的には、平行面１１ｆ１を設けなかった場合、フランジ状部３６の先端側の角部３６ａが開口側傾斜面１１ｆ２を越えた後、フランジ状部３６は４つの係止部１１ｆの開口側傾斜面１１ｆ２と底部側傾斜面１１ｆ３の間の角部に挟持されることとなり、真空採血管３ｃは採血管ホルダー本体１１に対して傾きやすい状態となる。真空採血管３ｃが採血管ホルダー本体１１に対して傾いていると、フランジ状部３６の基端側の角部３６ｂが４つの係止部１１ｆ毎に異なるタイミングで底部側傾斜面１１ｆ３と当接する場合があり、クリック感が連続的に生じる結果、真空採血管３ｃの適切な配置を使用者が把握し難い可能性がある。 In this example, the parallel surface 11f1 is provided between the opening side inclined surface 11f2 and the bottom side inclined surface 11f3 so that this click feeling is appropriately generated. Specifically, when the parallel surface 11f1 is not provided, after the corner portion 36a on the tip end side of the flange-shaped portion 36 exceeds the opening side inclined surface 11f2, the flange-shaped portion 36 becomes the opening side of the four locking portions 11f. It will be sandwiched between the corners between the inclined surface 11f2 and the bottom inclined surface 11f3, and the vacuum collecting blood vessel 3c will be easily tilted with respect to the blood collecting tube holder main body 11. When the vacuum blood collection tube 3c is tilted with respect to the blood collection tube holder main body 11, the corner portion 36b on the base end side of the flange-shaped portion 36 comes into contact with the bottom side inclined surface 11f3 at different timings for each of the four locking portions 11f. In some cases, as a result of continuous click feeling, it may be difficult for the user to grasp the appropriate arrangement of the vacuum blood collection tube 3c.
　これに対し、開口側傾斜面１１ｆ２と底部側傾斜面１１ｆ３の間に平行面１１ｆ１を設けることで、フランジ状部３６の先端側の角部３６ａが開口側傾斜面１１ｆ２を越えた後の真空採血管３ｃの傾きを防止することが可能となるため、フランジ状部３６の基端側の角部３６ｂを略同じタイミングで４つの係止部１１ｆの底部側傾斜面１１ｆ３と当接させて、適切なクリック感を生じさせることができる。 On the other hand, by providing the parallel surface 11f1 between the opening side inclined surface 11f2 and the bottom side inclined surface 11f3, vacuum sampling is performed after the corner portion 36a on the tip side of the flange-shaped portion 36 exceeds the opening side inclined surface 11f2. Since it is possible to prevent the blood vessel 3c from tilting, it is appropriate to bring the corner portion 36b on the base end side of the flange-shaped portion 36 into contact with the bottom side inclined surface 11f3 of the four locking portions 11f at substantially the same timing. It is possible to generate a nice click feeling.
　この例ではさらに、段差部１１ｅ１と底部側傾斜面１１ｆ３の底部１３側の端（頂面１１ｅ３との境界）の間の距離Ｄ１をフランジ状部３６の軸方向寸法Ｄ２よりも小さく設定する（換言すれば、段差部１１ｅ１から距離Ｄ２だけ離れた位置において頂面１１ｅ３よりも突出するように底部側傾斜面１１ｆ３を設ける）ことで、底部側傾斜面１１ｆ３の中心軸に対する傾斜角度θを約５°と小さく設定することを可能としている。距離Ｄ１をフランジ状部３６の軸方向寸法Ｄ２よりも小さく設定することで、フランジ状部３６を段差部１１ｅ１と底部側傾斜面１１ｆ３の間に挟持してフランジ状部３６に対する底部側傾斜面１１ｆ３の押圧力を高めることが可能となるため、傾斜角度θを小さく設定した場合にも確実に真空採血管３ｃの脱落を防止することができる。 In this example, the distance D1 between the step portion 11e1 and the bottom 13-side end (boundary with the top surface 11e3) of the bottom inclined surface 11f3 is further set smaller than the axial dimension D2 of the flange-shaped portion 36 (in other words). Then, the bottom side inclined surface 11f3 is provided so as to protrude from the top surface 11e3 at a position separated from the step portion 11e1 by the distance D2), so that the inclination angle θ of the bottom side inclined surface 11f3 with respect to the central axis is about 5 °. It is possible to set it small. By setting the distance D1 smaller than the axial dimension D2 of the flange-shaped portion 36, the flange-shaped portion 36 is sandwiched between the stepped portion 11e1 and the bottom-side inclined surface 11f3, and the bottom-side inclined surface 11f3 with respect to the flange-shaped portion 36 is sandwiched. Since it is possible to increase the pressing force of the vacuum collecting tube 3c, it is possible to reliably prevent the vacuum collecting tube 3c from falling off even when the inclination angle θ is set small.
　そして、傾斜角度θを小さく設定することで、真空採血管３ｃの採血管ホルダー１からの抜去時の抵抗を軽減することができる。すなわち、この例の係止部１１ｆによれば、真空採血管３ｃの脱落の防止と抜去の容易性を両立させることができる。 Then, by setting the inclination angle θ to be small, it is possible to reduce the resistance of the vacuum blood collection tube 3c when it is removed from the blood collection tube holder 1. That is, according to the locking portion 11f of this example, it is possible to achieve both prevention of the vacuum collecting tube 3c from falling off and ease of removal.
　なお、係止部１１ｆの形状は、このような台形状に限定されるものではなく、ピラミッド状、ドーム状又は角柱状等、その他の適宜の形状であってもよい。また、例えばクリック感を重要視しない場合には、平行面１１ｆ１を有さない形状に係止部１１ｆを構成してもよい。また、開口側傾斜面１１ｆ２及び底部側傾斜面１１ｆ３は、曲面から構成されるものであってもよい。また、開口側傾斜面１１ｆ２及び底部側傾斜面１１ｆ３の傾斜角度が特に限定されないことは、言うまでもない。 The shape of the locking portion 11f is not limited to such a trapezoidal shape, and may be another appropriate shape such as a pyramid shape, a dome shape, or a prismatic shape. Further, for example, when the click feeling is not important, the locking portion 11f may be configured in a shape that does not have the parallel surface 11f1. Further, the opening side inclined surface 11f2 and the bottom side inclined surface 11f3 may be formed of a curved surface. Needless to say, the inclination angles of the opening side inclined surface 11f2 and the bottom side inclined surface 11f3 are not particularly limited.
　このように、採血管ホルダー本体１１の内周面に第１の当接部１１ｄ及び第２の当接部１１ｅを設け、第２の当接部１１ｅに係止部１１ｆを設けた場合にも、シールタイプの真空採血管３ｃを安定的に保持して脱落を防止することができる。また、この場合においても、オーバーキャップタイプの真空採血管３ａ及びゴム栓キャップタイプの真空採血管３ｂを、図１に示す例と同様に保持して脱落を防止可能であることは言うまでもない。 As described above, even when the first contact portion 11d and the second contact portion 11e are provided on the inner peripheral surface of the blood collection tube holder main body 11 and the locking portion 11f is provided on the second contact portion 11e. , The seal type vacuum collection tube 3c can be stably held and prevented from falling off. Further, in this case as well, it goes without saying that the overcap type vacuum collection tube 3a and the rubber stopper cap type vacuum collection tube 3b can be held in the same manner as in the example shown in FIG. 1 to prevent them from falling off.
　なお、第１の当接部１１ｄ及び第２の当接部１１ｅの個数は、特に限定されるものではなく、任意の個数を採用することができる。また、採血管ホルダー本体１１の内周面に第２の当接部１１ｅのみを設けるようにしてもよいし、採血管ホルダー本体１１の内周面に第１の当接部１１ｄのみを設け、圧接部材２２に係止部２７を設けるようにしてもよい。また、第１の当接部１１ｄ及び第２の当接部１１ｅを、高い方の頂面１１ｄ４、１１ｅ４が真空採血管３ａ，３ｂの外周面に当接するように構成してもよい。また、係止部１１ｆは、採血管ホルダー本体１１の内周面において第２の当接部１１ｅとは別個に設けられるものであってもよい。 The number of the first contact portion 11d and the second contact portion 11e is not particularly limited, and any number can be adopted. Further, only the second contact portion 11e may be provided on the inner peripheral surface of the blood collection tube holder main body 11, or only the first contact portion 11d may be provided on the inner peripheral surface of the blood collection tube holder main body 11. The pressure welding member 22 may be provided with a locking portion 27. Further, the first contact portion 11d and the second contact portion 11e may be configured so that the higher top surfaces 11d4 and 11e4 are in contact with the outer peripheral surfaces of the vacuum collection tubes 3a and 3b. Further, the locking portion 11f may be provided separately from the second contact portion 11e on the inner peripheral surface of the blood collection tube holder main body 11.
　図１０は、図６に示す例において舌状突出片２０を省略した場合の一例を示した図である。この例では、舌状突出片２０と共に第２の凹部１１ｉの追加凹部１１ｉ１を省略している。そして、第２の補強片２６の寸法及び形状を適宜に調整すると共に、真空採血管３ａ，３ｂ，３ｃの挿入によって圧接部材２２が揺動変形した場合に屈曲部２４の先端部を第２の凹部１１ｉの底面に接触させることで十分な保持力が得られるようにしている。このように、保持部材１２のみによって十分な保持力が得られるような場合には、舌状突出片２０を省略するようにしてもよい。 FIG. 10 is a diagram showing an example in the case where the tongue-shaped protruding piece 20 is omitted in the example shown in FIG. In this example, the additional recess 11i1 of the second recess 11i is omitted together with the tongue-shaped projecting piece 20. Then, the size and shape of the second reinforcing piece 26 are appropriately adjusted, and when the pressure contact member 22 swings and deforms due to the insertion of the vacuum collecting tubes 3a, 3b, 3c, the tip portion of the bent portion 24 is seconded. A sufficient holding force can be obtained by contacting the bottom surface of the recess 11i. As described above, when a sufficient holding force can be obtained only by the holding member 12, the tongue-shaped protruding piece 20 may be omitted.
　なお、屈曲部２４の先端部を第２の凹部１１ｉの底面に接触させるのではなく、圧接部材２２に第１の補強片２５を追加することで、十分な保持力が得られるようにしてもよい。また、屈曲部２４の先端部が採血管ホルダー本体１１の内周面における第２の凹部１１ｉ以外の部分に接触するように、第２の凹部１１ｉを構成するようにしてもよい。また、係止部１１ｆは、採血管ホルダー本体１１の内周面において第２の当接部１１ｅとは別個に設けられるものであってもよいし、圧接部材２２に設けられるものであってもよい。また、図示は省略するが、図１に示す例において舌状突出片２０を省略するようにしてもよい。 It should be noted that the tip of the bent portion 24 is not brought into contact with the bottom surface of the second recess 11i, but the first reinforcing piece 25 is added to the pressure contact member 22 so that a sufficient holding force can be obtained. Good. Further, the second recess 11i may be configured so that the tip end portion of the bent portion 24 comes into contact with a portion other than the second recess 11i on the inner peripheral surface of the blood collection tube holder main body 11. Further, the locking portion 11f may be provided on the inner peripheral surface of the blood collection tube holder main body 11 separately from the second contact portion 11e, or may be provided on the pressure contact member 22. Good. Further, although not shown, the tongue-shaped protruding piece 20 may be omitted in the example shown in FIG.
　図１１は、オスコネクタ１５ａに代えてメスコネクタ１５ｂを針基１５の先端部に設けた場合の一例を示している。図１１に示すように、採血に用いられるシリンジ６は、一般に採血針管の針基（図示せず）を接続するためのオスコネクタ６１を先端にそなえているため、このように、針基１５にメスコネクタ１５ｂを設けることで、シリンジ６のオスコネクタ６１を採血管ホルダー１に直接接続することが可能となる。 FIG. 11 shows an example in which a female connector 15b is provided at the tip of the needle base 15 instead of the male connector 15a. As shown in FIG. 11, the syringe 6 used for blood collection generally has a male connector 61 at the tip for connecting the needle base (not shown) of the blood collection needle tube. Therefore, the needle base 15 is described in this way. By providing the female connector 15b, the male connector 61 of the syringe 6 can be directly connected to the blood collection tube holder 1.
