来光ＩＪノは血液収納容器内の血液を患者に人、ｌ、′
ｒ輸血する際に使用されるセラ（・に関するものである
。[Detailed Description of the Invention] Raikou IJ is designed to supply blood in a blood storage container to a patient.
rRelated to Sera (・) used in blood transfusions.
たとえば手術等において、大１１１−出血を伴なう患者
に対しては大Ｈ，Ｂ輸血を行なう心安かある。For example, during surgery, it is safe to perform large H and B blood transfusions for patients with large 111-bleeding.
従来こうした大ｊ、１輸血、たとえば一度に１文〜５文
の輸血を必要とする手術の際には、頻繁に血液バッグ等
の血液収納容器を取り換えて必要量を輸血しなければな
らず、非常に手間のかかるものであり、しかも患者の正
確な輸血量の測定や１陥血速度の調整も困難であった。Conventionally, during surgeries that require one blood transfusion, for example, one to five blood transfusions at a time, the blood storage container such as a blood bag must be frequently replaced to transfuse the required amount. This method is extremely time-consuming, and it is also difficult to accurately measure the amount of blood transfused to the patient and to adjust the rate of blood transfusion.
また保存血液は、採血後２４蒔間以内にマイクロアグリ

あるが、大量輸血のほとんどは緊急時であることも手伝
って、従来必ずしも充分な対処がなされていなかった。In addition, in stored blood, microaggregates (fine aggregates) begin to form within 24 minutes after blood collection, and their formation becomes noticeable after the storage period exceeds one week. These microaggregates can cause embolism in the lungs, brain, etc. during large, l, l, ring+fi+ cases, so they need to be removed, but it also helps that most large-scale blood transfusions are for emergencies. , which has not always been adequately addressed in the past.
本発明はこうした現状に鑑みて提案されたものであり、
大量輸血を安全にかつ安定して行ない得るようにした輸
血セットを提供しようとするものである。The present invention was proposed in view of the current situation, and
The purpose of the present invention is to provide a blood transfusion set that allows large-scale blood transfusion to be carried out safely and stably.
以下本発明の一実施例を添付図面に従って説明する。An embodiment of the present invention will be described below with reference to the accompanying drawings.

０μであるのものが使用されている。In 1Δ, l is a needle for penetrating the blood outlet 3 of the blood bag 2 or the like, and a micro-aggregate removal filter 4 is provided downstream of this penetrating side l. This micro-aggregate removal filter 4 has a capacity of 10 pL to 4
A material with a value of 0μ is used.
５はリザーバで、たとえばΦ欠質プラスチック製の袋状
となっており、本実施例ではその容：１ｉをｌｕ〜５文
としている。Reference numeral 5 denotes a reservoir, which is in the form of a bag made of, for example, Φ-defective plastic, and in this embodiment, its capacity: 1i is set to lu to 5 sentences.
また６は送血ポンプ７に装着されるローリングチューブ

＋（ｎ ｉｆｋをド流側に送るようになっている。Further, 6 is a rolling tube attached to the blood pump 7, which is tightened by the blood pump 7 to send +(nifk in the tube to the negative flow side).
なお送血ポンプ７は、流１１５−が１０ｍ１／分〜ｌ
ＯＯｍｌ／分程度の能力をもたせるのか望ましい。The blood pump 7 has a flow rate 115 of 10 m1/min to 1
It is desirable to have a capacity of about OOml/min.

なるよう送血ポンプ７を制御している。8 is a drip tube, and in the present invention, a pressure monitor line 10 connected to a pressure gauge 9 is connected to this drip tube 8. This pressure cylinder 9 is linked with the blood pump 7 to control the blood pump 7 so that a predetermined pressure is maintained at all times.
その他図面において１１は輸血針、１２は前記各部品を
連結する送血チューブである。In other drawings, reference numeral 11 indicates a blood transfusion needle, and reference numeral 12 indicates a blood delivery tube that connects each of the above-mentioned parts.
本発明では上記した構成に加えて、たとえば送血ポンプ
