Description

本発明は、採血時に被採血者の腕を支持するための採血用枕に関する。   The present invention relates to a blood collection pillow for supporting a blood collection person's arm during blood collection.

例えば病院や診療所等で静脈血採血(以下、「採血」という)を行う際には、被採血者の腕を支持するための採血用枕が用いられている。従来の採血用枕は、被採血者の腕を支持するためのブロック状の枕本体と、枕本体を下方より支持するためのスタンド部材と、を備えている(例えば、特許文献1参照)。スタンド部材には、枕本体の床面からの高さ位置を調節するための高さ調節機構が設けられている。   For example, when collecting venous blood (hereinafter referred to as “blood collection”) in a hospital or clinic, a blood collection pillow is used to support the arm of the blood sample. A conventional pillow for blood collection includes a block-shaped pillow body for supporting the arm of a blood sample and a stand member for supporting the pillow body from below (for example, see Patent Document 1). The stand member is provided with a height adjustment mechanism for adjusting the height position of the pillow body from the floor surface.

上述したタイプの採血用枕では、次のような問題がある。採血を行う際には、被採血者は、着座した姿勢で腕を枕本体の上面に載置するようになる。しかしながら、枕本体の床面からの高さ位置が高い場合には、腕が床面に対して略平行となり、注射針を刺す腕の部位(例えば肘窩)が心臓よりも高い位置となるため、採血した血液が血管内に逆流するおそれがある。また、枕本体の床面からの高さ位置が低い場合には、被採血者の肘関節は屈曲した状態となるため、肘窩の静脈内圧が上昇せずに血管が浮き上がり難く、採血を容易に行うことができない。   The blood sampling pillow of the type described above has the following problems. When blood collection is performed, the blood sampler places his arm on the upper surface of the pillow body in a sitting posture. However, when the height position of the pillow body from the floor surface is high, the arm is substantially parallel to the floor surface, and the portion of the arm that pierces the injection needle (for example, the elbow socket) is higher than the heart. The collected blood may flow back into the blood vessel. In addition, when the height of the pillow body from the floor is low, the elbow joint of the blood sample is bent, so that the blood pressure does not rise easily without increasing the venous pressure in the elbow socket, making blood collection easy. Can not do.

The pillow for blood collection according to claim 6 of the present invention is a pillow for blood collection for supporting the arm of a blood sampler in an arm-down posture during blood collection,
A pillow main body having a support surface for supporting at least a portion from the elbow joint to the wrist joint of the blood collection subject's arm is provided, and the bending angle of the shoulder joint of the blood collection subject is 55 to 70 °. And a stepped portion is provided at the lower end portion of the support surface, and the height of the stepped portion is configured to be a height at which the blood joint of a blood sample can be dorsiflexed,
In relation to the pillow main body, a stand member for supporting the pillow main body from below is provided, and the stand member is provided at a stand main body portion having a height adjusting mechanism and an upper end portion of the stand main body portion. A mounting portion,
The pillow body includes an upper pillow body having the support surface, and a lower pillow body detachably attached to a lower surface of the upper pillow body,
A mounting recess is provided on the lower surface of the lower pillow body, and the mounting portion of the stand member is detachably mounted in the mounting recess .

本発明の請求項1に記載の採血用枕によれば、支持面は傾斜状に構成されているので、被採血者の腕はアームダウン姿勢で支持面に支持されるようになり、これにより注射針を刺す腕の部位(例えば肘窩)が心臓よりも低い位置となるため、血液の逆流を防止することができる。また、支持面は、被採血者の肩関節の屈曲角度が55〜70°となるように傾斜状に構成されている(換言すると、支持面の鉛直方向に対する角度が、肩関節の屈曲角度よりも約5°だけ大きい60〜75°である)ので、肘関節を伸展させた状態で腕を支持面に容易に支持させることができ、これにより、被採血者は安楽な姿勢を保つことができ、苦痛を感じることなく採血を受けることができる。また、支持面の下端部には段差部が設けられているので、被採血者の腕を支持面に支持させた際に、手関節を段差部に向けて背屈させることができる。この手関節の背屈によって生理学的に肘関節が伸展するようになり、肘関節の伸展位が約0°に保持される。これにより、肘窩の静脈内圧が高まって血管が浮き上がるようになり、採血を容易に行うことができる。また、一般に、被採血者の腕に対する注射針の刺入角度は約30°であるが、被採血者の肩関節の屈曲角度を例えば約60°に保持することにより、注射器(又は真空採血管)は地面に対して略平行となり、採血を容易に行うことができる。
また、支持面には保持用凹部が設けられているので、被採血者の腕の少なくとも一部(例えば、肘関節から手関節までの部位)をこの保持用凹部に収容保持させることにより、被採血者の腕を支持面に安定して支持させることができる。また、保持用凹部は支持面の長さ方向に延びており、その深さは、支持面の下端部から上端部に向けて漸増されているので、肘関節が支持面の上端部(保持用凹部の深さが深い部位)に収容保持されるとともに、手関節が支持面の下端部(保持用凹部の深さが浅い部位)に収容保持されるようになる。一般に、肘関節の太さは手関節の太さよりも太いので、上述のように収容保持されることにより、被採血者の腕の肘関節から手関節までの部位を保持用凹部に安定して収容保持することができる。
According to the pillow for blood collection described in claim 1 of the present invention, since the support surface is configured in an inclined shape, the blood collection subject's arm is supported by the support surface in an arm-down position, thereby Since the part of the arm that pierces the injection needle (for example, the elbow fossa) is positioned lower than the heart, the backflow of blood can be prevented. Further, the support surface is configured to be inclined so that the bending angle of the shoulder joint of the blood sample is 55 to 70 ° (in other words, the angle of the supporting surface with respect to the vertical direction is greater than the bending angle of the shoulder joint). Therefore, the arm can be easily supported on the supporting surface in a state where the elbow joint is extended, so that the blood sample can maintain a comfortable posture. Can receive blood without feeling pain. Moreover, since the step part is provided in the lower end part of the support surface, when a blood-collected person's arm is supported by a support surface, a wrist joint can be bent back toward a step part. Due to the dorsiflexion of the wrist joint, the elbow joint extends physiologically, and the extended position of the elbow joint is maintained at about 0 °. As a result, the venous pressure in the cubital fossa increases and the blood vessels rise, and blood can be collected easily. In general, the insertion angle of the injection needle with respect to the arm of the blood sample is about 30 °, but by holding the bending angle of the shoulder joint of the blood sample at, for example, about 60 °, the syringe (or vacuum blood collection tube) ) Is substantially parallel to the ground, and blood can be collected easily.
In addition, since the holding surface is provided with a holding recess, at least a part of the blood collection subject's arm (for example, a portion from the elbow joint to the wrist joint) is accommodated and held in the holding recess, thereby The arm of the blood sampler can be stably supported on the support surface. Further, the holding recess extends in the length direction of the support surface, and its depth is gradually increased from the lower end portion of the support surface toward the upper end portion. The hand joint is housed and held at the lower end of the support surface (portion where the depth of the holding recess is shallow). In general, the thickness of the elbow joint is larger than the thickness of the wrist joint, so that the portion from the elbow joint to the wrist joint of the blood sample's arm can be stably held in the holding recess by being held and held as described above. It can be stored and held.

また、本発明の請求項2に記載の採血用枕によれば、段差部の高さは3〜5cmであるので、手関節を段差部に向けて確実に背屈させることができる。また、手関節を背屈させた際に、手指の背側(又は拳部分)が枕本体の載置面(例えばテーブルの上面)に接触するようになり、これにより手関節を背屈させた所要の状態に容易に保持することができる。   Moreover, according to the pillow for blood collection of Claim 2 of this invention, since the height of a level | step-difference part is 3-5 cm, a wrist joint can be reliably bent back toward a level | step-difference part. In addition, when the wrist joint is bent back, the dorsal side (or fist part) of the fingers comes into contact with the mounting surface of the pillow body (for example, the upper surface of the table), thereby bending the wrist joint. It can be easily held in the required state.

また、本発明の請求項3に記載の採血用枕によれば、支持面の下端部の前方には握り棒が設けられているので、この握り棒を手で把持することにより、被採血者の腕を支持面に安定して支持させることができるとともに、駆血効果によって血管を効果的に浮き上がらせることができる。   Moreover, according to the pillow for blood collection described in claim 3 of the present invention, since the grip rod is provided in front of the lower end portion of the support surface, the blood sample can be collected by grasping the grip rod by hand. The arm can be stably supported on the support surface, and the blood vessel can be effectively lifted by the blood transducing effect.

また、本発明の請求項4に記載の採血用枕によれば、段差部の高さは3〜5cmであるので、手関節を段差部に向けて確実に背屈させることができる。また、手関節を背屈させた際に、手指の背側(又は拳部分)が枕本体の載置面(例えばテーブルの上面)に接触するようになり、これにより手関節を背屈させた所要の状態に容易に保持することができる。
更に、支持面の下端部の前方には握り棒が設けられているので、この握り棒を手で把持することにより、被採血者の腕を支持面に安定して支持させることができるとともに、駆血効果によって血管を効果的に浮き上がらせることができる。
Moreover, according to the pillow for blood collection of Claim 4 of this invention, since the height of a level | step-difference part is 3-5 cm, a wrist joint can be reliably bent back toward a level | step-difference part. In addition, when the wrist joint is bent back, the dorsal side (or fist part) of the fingers comes into contact with the mounting surface of the pillow body (for example, the upper surface of the table), thereby bending the wrist joint. It can be easily held in the required state.
Furthermore, since a grip rod is provided in front of the lower end portion of the support surface, by grasping the grip rod by hand, the blood collection person's arm can be stably supported on the support surface, The blood vessel can be effectively lifted by the blood-feeding effect.

また、本発明の請求項5に記載の採血用枕によれば、握り棒を把持した被採血者の手関節が段差部に向けて20〜30°の角度で背屈可能に構成されているので、アームダウン姿勢で肘関節の伸展位を約0度に保持するとともに、肘窩の静脈内圧が高まって血管が浮き上がる。 Moreover, according to the pillow for blood collection of Claim 5 of this invention , the wrist joint of the blood-collecting person who hold | gripped the grip rod is comprised so that a dorsiflexion is possible at an angle of 20-30 degrees toward a level | step-difference part. Therefore, the extension position of the elbow joint is maintained at about 0 degrees in the arm-down posture, and the venous pressure in the elbow fossa is increased to raise the blood vessel.

また、本発明の請求項6に記載の採血用枕によれば、枕本体を下方より支持するためのスタンド部材が設けられているので、被採血者の身長等に応じて、スタンド本体部の高さ調節機構により枕本体の床面からの高さ位置を適宜調節することができる。また、枕本体は、支持面を有する上枕本体と、装着用凹部を有する下枕本体とに分割可能であるので、下枕本体を上枕本体から取り外すことにより、上枕本体をテーブルの上などに載置して使用することができる。従って、用途等に応じて、2通りの使用方法(即ち、下枕本体を上枕本体に取り付けて枕本体をスタンド部材に支持して使用する方法及び下枕本体を上枕本体から取り外して上枕本体をテーブルの上面などに載置して使用する方法)を適宜選択することができる。 Moreover, according to the pillow for blood collection of Claim 6 of this invention, since the stand member for supporting a pillow main body from the downward direction is provided, according to the height etc. of a blood-collected person, The height position from the floor surface of the pillow body can be adjusted as appropriate by the height adjustment mechanism. Also, the pillow body can be divided into an upper pillow body having a support surface and a lower pillow body having a mounting recess, so that by removing the lower pillow body from the upper pillow body, the upper pillow body is placed on the table. It can be mounted and used. Therefore, depending on the application, etc., there are two usage methods (i.e., a method in which the lower pillow body is attached to the upper pillow body and the pillow body is supported by the stand member , and the lower pillow body is removed from the upper pillow body. A method of using the pillow body on the top surface of the table or the like can be selected as appropriate.

以下、添付図面を参照して、本発明に従う採血用枕の一実施形態について説明する。図1は、本発明の一実施形態による採血用枕を示す斜視図であり、図2は、図1の採血用枕の側面図であり、図3は、図1の採血用枕の使用状態を示す斜視図であり、図4は、図3中のA−A線による採血用枕の断面図である。   Hereinafter, an embodiment of a pillow for blood collection according to the present invention will be described with reference to the accompanying drawings. 1 is a perspective view showing a blood collection pillow according to an embodiment of the present invention, FIG. 2 is a side view of the blood collection pillow of FIG. 1, and FIG. 3 is a use state of the blood collection pillow of FIG. FIG. 4 is a cross-sectional view of the pillow for blood collection along the line AA in FIG.

図1及び図2を参照して、図示の採血用枕2は、断面略直角三角形状の枕本体4を備えている。枕本体4には傾斜状の支持面6が設けられており、支持面6の幅方向中央部には、その長さ方向に延びる保持用凹部8が設けられている。保持用凹部8の深さは、支持面6の下端部から上端部に向けて漸増されている(図2参照)。これにより、支持面6の幅方向中央部(保持用凹部8)の鉛直方向(図2において上下方向)に対する角度θ1は、支持面6の幅方向両端部の鉛直方向に対する角度θ2よりも大きく構成されるようになる。本実施形態では、角度θ1は65°に設定され、また角度θ2は60°に設定されている。   1 and 2, the illustrated blood collection pillow 2 includes a pillow body 4 having a substantially right-angled triangular cross section. The pillow body 4 is provided with an inclined support surface 6, and a holding recess 8 extending in the length direction is provided at the center in the width direction of the support surface 6. The depth of the holding recess 8 is gradually increased from the lower end portion of the support surface 6 toward the upper end portion (see FIG. 2). Thus, the angle θ1 with respect to the vertical direction (vertical direction in FIG. 2) of the center portion in the width direction (holding recess 8) of the support surface 6 is configured to be larger than the angle θ2 with respect to the vertical direction at both end portions in the width direction of the support surface 6. Will come to be. In the present embodiment, the angle θ1 is set to 65 °, and the angle θ2 is set to 60 °.

また、支持面6の下端部には段差部10が設けられており、この段差部10によって、支持面6の下端縁は、枕本体4の下面よりも所定高さh(例えば4cm程度)だけ高い位置に位置されるようになる。   Further, a step portion 10 is provided at the lower end portion of the support surface 6, and the step portion 10 causes the lower end edge of the support surface 6 to be a predetermined height h (for example, about 4 cm) from the lower surface of the pillow body 4. It will be located at a high position.

また、枕本体4は、クッション材(図示せず)と、クッション材を覆うカバー(図示せず)とから構成されている。クッション材は、例えばウレタンなどの低反発性素材から形成され、またカバーは、例えばポリエステルやレザーなどから形成されている。なお、カバーは、滑り難い材質のものを用いるのが好ましい。   Moreover, the pillow main body 4 is comprised from the cushion material (not shown) and the cover (not shown) which covers a cushion material. The cushion material is made of a low resilience material such as urethane, and the cover is made of polyester or leather, for example. The cover is preferably made of a material that does not slip easily.

なお、枕本体4のサイズは、高さH:18cm、幅W:20cm、支持面6の長さL:27cmに構成されている。支持面6の長さLは、被採血者12の腕14の少なくとも肘関節16から手関節18までの部位を支持可能な長さ、例えば26〜30cm程度に構成するのが好ましく、このように構成することにより、被採血者12の肘関節16が支持面6に確実に支持され、後述するように肘関節16の伸展位を約0度に確実に保持させることができる。   In addition, the size of the pillow body 4 is configured such that the height H is 18 cm, the width W is 20 cm, and the length L of the support surface 6 is 27 cm. The length L of the support surface 6 is preferably configured to be a length capable of supporting at least a portion of the arm 14 of the blood sample 12 from the elbow joint 16 to the wrist joint 18, for example, about 26 to 30 cm. By configuring, the elbow joint 16 of the blood sample 12 is reliably supported by the support surface 6, and the extended position of the elbow joint 16 can be reliably held at about 0 degrees as will be described later.

支持面6の下端部における両端部にはそれぞれ、接続部20が前方(図2において左方向)に延びて設けられている。これら一対の接続部20の各先端部には、略水平方向に延びる握り棒22が支持されている。握り棒22の高さ位置は、支持面6の下端縁と同じ高さ位置又はこれよりも幾分低い高さ位置に設定される。   Connection portions 20 are provided at both end portions of the lower end portion of the support surface 6 so as to extend forward (leftward in FIG. 2). A grip rod 22 extending in a substantially horizontal direction is supported at each tip of the pair of connection portions 20. The height position of the grip bar 22 is set to the same height position as the lower end edge of the support surface 6 or a slightly lower height position.

図3及び図4をも参照して、上述した採血用枕2の使用方法について説明する。まず、枕本体4を例えばテーブル23の上面(載置面)に載置する。被採血者12は、採血する腕14の少なくとも肘関節16から手関節18までの部位を支持面6の保持用凹部8に支持させるとともに、握り棒22を手24で把持する。このとき、枕本体4のクッション材は低反発性素材から形成されているので、被採血者12の腕14が保持用凹部8にやや沈み込むようになり、腕14が支持面6に安定して支持される。一般に、肘関節16の太さは手関節18の太さよりも太いので、肘関節16が支持面6の上端部(保持用凹部8の深さが深い部位)に支持されるとともに、手関節18が支持面6の下端部(保持用凹部8の深さが浅い部位)に支持されることにより、被採血者12の腕14の肘関節16から手関節18までの部位を保持用凹部8に安定して収容保持することができる。   With reference also to FIG.3 and FIG.4, the usage method of the pillow 2 for blood collection mentioned above is demonstrated. First, the pillow body 4 is placed on the upper surface (mounting surface) of the table 23, for example. The blood sampled person 12 supports at least a portion of the arm 14 from which blood is collected from the elbow joint 16 to the wrist joint 18 in the holding recess 8 of the support surface 6 and holds the grip rod 22 with the hand 24. At this time, since the cushion material of the pillow body 4 is formed of a low repulsive material, the arm 14 of the blood sample 12 slightly sinks into the holding recess 8, and the arm 14 is stabilized on the support surface 6. Supported. In general, since the elbow joint 16 is thicker than the wrist joint 18, the elbow joint 16 is supported by the upper end portion of the support surface 6 (the portion where the holding recess 8 is deep) and the wrist joint 18. Is supported by the lower end portion of the support surface 6 (the portion where the depth of the holding recess 8 is shallow), so that the portion from the elbow joint 16 to the wrist joint 18 of the arm 14 of the blood sample 12 becomes the holding recess 8. It can be stably housed and held.

被採血者12の腕14を支持面6の保持用凹部8に支持させると、腕14の中心軸線は、支持面6の幅方向両端部と略平行となるので、被採血者12の肩関節26の屈曲角度θ3(即ち、腕14の中心軸線の鉛直方向に対する角度)は、支持面6の幅方向両端部の鉛直方向に対する角度θ2とほぼ等しい約60°となる。換言すると、肩関節26の屈曲角度θ3は、支持面6の保持用凹部8の鉛直方向に対する角度θ1よりも約5°だけ小さい角度となる。これにより、腕14がアームダウン姿勢で支持面6に支持され、肘関節16の位置を心臓(心尖部)よりも低くすることができる。また、肘関節16を伸展させた状態で腕14を支持面6に容易に支持させることができ、それ故に、被採血者12は安楽な姿勢を保つことができ、苦痛を感じることなく採血を受けることができる。   When the arm 14 of the blood sample 12 is supported by the holding recess 8 of the support surface 6, the central axis of the arm 14 is substantially parallel to both ends of the support surface 6 in the width direction. The bending angle θ3 of 26 (that is, the angle of the central axis of the arm 14 with respect to the vertical direction) is approximately 60 ° that is substantially equal to the angle θ2 with respect to the vertical direction of both ends of the support surface 6 in the width direction. In other words, the bending angle θ3 of the shoulder joint 26 is smaller by about 5 ° than the angle θ1 of the supporting surface 6 with respect to the vertical direction of the holding recess 8. Thereby, the arm 14 is supported by the support surface 6 in an arm-down posture, and the position of the elbow joint 16 can be made lower than the heart (apex). In addition, the arm 14 can be easily supported on the support surface 6 with the elbow joint 16 extended, and thus the blood sample 12 can maintain a comfortable posture and blood can be collected without feeling painful. Can receive.

なお、このように肘関節16の位置を心臓よりも低くするとともに、苦痛を感じることなく採血を受けるためには、被採血者12の肩関節26の屈曲角度θ3は55〜70°(換言すると、支持用凹部8の鉛直方向に対する角度θ1は60〜75°)であるのが好ましく、60〜65°(換言すると、支持用凹部8の鉛直方向に対する角度θ1は65〜70°)であるのがより好ましい。屈曲角度θ3が55°よりも小さいと、被採血者12の肘関節16が過伸展となり、無理な体勢を維持しなければならないために苦痛を感じるようになる。また、屈曲角度θ3が70°よりも大きいと、被採血者12の肘関節16の位置が心臓よりも高くなり、採血した血液が血管内に逆流するおそれがある。   In addition, in order to make the position of the elbow joint 16 lower than the heart and collect blood without feeling pain, the bending angle θ3 of the shoulder joint 26 of the blood sample 12 is 55 to 70 ° (in other words, The angle θ1 with respect to the vertical direction of the support recess 8 is preferably 60 to 75 °, and 60 to 65 ° (in other words, the angle θ1 with respect to the vertical direction of the support recess 8 is 65 to 70 °). Is more preferable. When the bending angle θ3 is smaller than 55 °, the elbow joint 16 of the blood sample 12 becomes overextended, and it becomes difficult to maintain an unreasonable posture. When the bending angle θ3 is larger than 70 °, the position of the elbow joint 16 of the blood sample 12 becomes higher than the heart, and the collected blood may flow back into the blood vessel.

また、支持面6の下端部には段差部10が設けられているので、握り棒22を手24で把持した際に、被採血者12の手関節18を段差部10に向けて背屈角度θ4(20〜30°程度)で背屈させることができる。この手関節18の背屈によって、生理学的に肘関節16が伸展するようになる。このように、アームダウン姿勢で肘関節16の伸展位を約0度に保持するとともに、握り棒22を手4で把持することにより、肘窩28の静脈内圧が高まって血管が浮き上がるようになる。   Further, since the step portion 10 is provided at the lower end portion of the support surface 6, the dorsiflexion angle with the wrist joint 18 of the blood sample 12 facing the step portion 10 when the gripping rod 22 is gripped by the hand 24. The back can be bent at θ4 (about 20 to 30 °). Due to the dorsiflexion of the wrist joint 18, the elbow joint 16 extends physiologically. Thus, while holding the extended position of the elbow joint 16 at about 0 degrees in the arm-down posture, and holding the gripping rod 22 with the hand 4, the venous pressure of the elbow socket 28 increases and the blood vessel comes to rise. .

なお、段差部10の高さhは、3.0〜5.0cmであるのが好ましく、3.5〜4.5cmであるのがより好ましい。段差部10の高さhをこのように構成することにより、手関節18を確実に背屈させることができ、また、手関節18を背屈させた際に手指の背側(又は拳部分)がテーブル23の上面に接触するようになり、手関節18を背屈させた所要の状態に容易に保持することができる。段差部10の高さhが3.0cmよりも小さいと、手関節18を十分に背屈させることができず、また、段差部10の高さhが5.0cmよりも大きいと、手関節18を背屈させた際に手指の背側(又は拳部分)がテーブル23の上面に接触せず、手関節18を背屈させた状態に保持するのが難しくなる。   In addition, it is preferable that the height h of the level | step-difference part 10 is 3.0-5.0 cm, and it is more preferable that it is 3.5-4.5 cm. By configuring the height h of the stepped portion 10 in this way, the wrist joint 18 can be reliably bent back, and when the wrist joint 18 is bent back, the back side of the finger (or fist part) Comes into contact with the upper surface of the table 23 and can be easily held in a required state in which the wrist joint 18 is bent back. If the height h of the stepped portion 10 is smaller than 3.0 cm, the wrist joint 18 cannot be sufficiently dorsiflexed, and if the height h of the stepped portion 10 is larger than 5.0 cm, the wrist joint When the back 18 is bent back, the dorsal side (or fist part) of the fingers does not come into contact with the upper surface of the table 23, and it becomes difficult to hold the wrist joint 18 in the back bent state.

上述のように腕14を支持面6に支持させた後に、被採血者12の上腕部に駆血帯(図示せず)を巻き付け、例えば肘窩28に消毒を施した後に注射器30の注射針32を刺し、採血を行う。上述のように注射針32を刺す肘関節16の位置は心臓よりも低いので、血液の逆流を防止することができる。なお、一般に、被採血者12の腕14に対する注射針32の刺入角度θ5は約30°であるが、本実施形態では、被採血者12の肩関節26の屈曲角度θ3は約60°であるので、注射器30は地面に対して略平行となり、採血を容易に行うことができる。   After the arm 14 is supported on the support surface 6 as described above, a tourniquet (not shown) is wrapped around the upper arm of the blood sample 12 and, for example, the sternum 28 is sterilized and then the needle of the syringe 30 is injected. 32 is stabbed and blood is collected. As described above, the position of the elbow joint 16 that pierces the injection needle 32 is lower than that of the heart, so that the backflow of blood can be prevented. In general, the insertion angle θ5 of the injection needle 32 with respect to the arm 14 of the blood sample 12 is about 30 °, but in this embodiment, the bending angle θ3 of the shoulder joint 26 of the blood sample 12 is about 60 °. Therefore, the syringe 30 is substantially parallel to the ground, and blood can be collected easily.
