【考案の詳細な説明】
〈技術分野〉
本考案は血液ガス分析のための血液サンプルを
採取するためのシリンジに関するものである。[Detailed Description of the Invention] <Technical Field> The present invention relates to a syringe for collecting a blood sample for blood gas analysis.
〈従来技術〉
血液ガス分析のためのシリンジ採血において、
採血後シリンジ内に残留した空気を排出するため
に、採血針の先端を上にしてシリンジ内のプラン
ジヤを前進せしめて採血針内の血液、シリンジ内
の空気を排出せしめた後採血針の先端開口を密閉
する必要があるので、採血針から溢出した血液を
をガーゼ等を使用して拭い取らねばならず感染の
危険性が大であつた。<Prior art> In syringe blood collection for blood gas analysis,
In order to discharge the air remaining in the syringe after blood collection, move the plunger inside the syringe forward with the tip of the blood collection needle facing upwards, and then open the tip of the blood collection needle after discharging the blood inside the blood collection needle and the air inside the syringe. Since the needle must be sealed tightly, the blood spilling from the blood collection needle must be wiped off using gauze or the like, which poses a high risk of infection.
〈目的〉
本考案は上記の欠点を解決し、採血時の汚染の
危険性のない血液ガス分析用シリンジを提供する
ことを目的とするものである。<Objective> The object of the present invention is to solve the above-mentioned drawbacks and provide a syringe for blood gas analysis that is free from the risk of contamination during blood collection.
〈実施例〉 本考案の一実施例を図面に基いて説明する。<Example> An embodiment of the present invention will be described based on the drawings.

底部にシール材５、内中間部に吸液材４が収容さ
れたことを特徴とするものである。 In the drawing, 1 is a syringe composed of an outer cylinder 6 and a plunger 7 having a gasket 8 at its tip that slides inside the outer cylinder, 2 is a blood collection needle attached to the tip of the syringe, and 3 is a removable needle. This is a protector that surrounds a blood collection needle, and is similar to a conventional syringe, but it is characterized in that a sealing material 5 is housed in the inner bottom of the protector 3, and a liquid absorbing material 4 is housed in the inner middle part. be.
上記構成において採血後、採血針２の先端を上
にしてプロテクタ３を該採血針に被冠し、採血針
の先端を吸液材内あるいは吸液材を貫通せしめた
状態でプランジヤ７を前進せしめると、採血針か

の空気が完全に排出されてからシリンジを最前進
せしめると採血針の先端がシール材５内に埋没し
て密閉され、シリンジ内は大気と遮断される。 After blood is collected in the above configuration, the protector 3 is placed on the blood collecting needle 2 with its tip facing upward, and the plunger 7 is advanced with the tip of the blood collecting needle inserted into or through the liquid absorbing material. The blood that overflows from the blood collection needle is absorbed by the absorbent material, and when the air in the syringe is completely exhausted and the syringe is moved forward, the tip of the blood collection needle is buried in the sealing material 5 and sealed, and the syringe is closed. The inside is cut off from the atmosphere.
上記シール材として適宜の材料を使用すること
ができ、シリコーンシーラント、パラフイン、あ
るいはポリウレタン等が好適であり、吸液材とし
てはパルプ材が適当である。 Any suitable material can be used as the sealing material, and silicone sealant, paraffin, polyurethane, etc. are suitable, and pulp material is suitable as the liquid-absorbing material.
〈効果〉
本考案はプロテクタの内中間部に吸液材を配置
したので、採血時の空気排出に伴う溢出血液が吸
液材に吸収され採血者との血液の接触がないので
感染の危険性を伴うことはない。<Effects> In this invention, a liquid-absorbing material is placed in the middle part of the protector, so the blood that spills out due to the air discharge during blood collection is absorbed by the liquid-absorbing material, and there is no contact between the blood and the person collecting the blood, thereby reducing the risk of infection. It is not accompanied by
