【考案の詳細な説明】
本考案は採血管の改良に関するものであり、血
液検査に必要な抗凝固剤が混和されていない血液
を所望量採血できるようにしたものである。[Detailed Description of the Invention] The present invention relates to an improvement in a blood collection tube, and is capable of collecting a desired amount of blood that is not mixed with an anticoagulant necessary for a blood test.
供血者より採血した血液は血液型の判定のほか
に、梅毒血清学的検査や輸血後の肝炎防止のため
のトランスアミナーゼ検査、さらにはHB抗原検
査等受血者に有害に働く諸要因の有無、供血者の
生化学検査を行なつている。 In addition to determining the blood type, the blood collected from the donor is tested for syphilis serology, transaminase testing to prevent hepatitis after blood transfusion, and HB antigen testing to determine whether there are any factors that may be harmful to the recipient. We are conducting biochemical tests on blood donors.
従来、採血バツグに採血するに際しては採血針
を供血者の静脈に穿刺し、採血管を通して血液を
所定量採血バツグ内に流入せしめている。しかし
採血バツグ内にはあらかじめ抗凝固剤が入つてい
るため、前記した各種検査を行なうためには採血
バツグ内の血液は好ましくなく、抗凝固剤の混入
しない血液が必要となる。 Conventionally, when collecting blood into a blood collection bag, a blood collection needle is inserted into the donor's vein, and a predetermined amount of blood is allowed to flow into the blood collection bag through the blood collection tube. However, since an anticoagulant is already contained in the blood collection bag, the blood in the blood collection bag is not desirable in order to perform the various tests described above, and blood that is not contaminated with anticoagulant is required.
このため、従来では血液を所定量採血した後、
採血管の採血針側から約10cmのところを鉗子で止
め、鉗子から採血バツグ側のところをアルミリン
グか結び目をつくつて止めた後、鉗子とアルミリ
ング（結び目）の間の採血管をハサミで切断し、
鉗子をゆるめて切り口から検査用試験管に血液を
必要に応じて５〜10ml採血していたものである。 For this reason, conventionally, after collecting a predetermined amount of blood,
Use forceps to secure the blood collection tube approximately 10cm from the blood collection needle side, tie an aluminum ring or knot between the forceps and the blood collection bag, and then use scissors to secure the blood collection tube between the forceps and the aluminum ring (knot). cut,
The forceps were loosened and 5 to 10 ml of blood was collected from the incision into a test tube as needed.
しかしながらこのような方法では手順や操作が
煩雑で、それなりの熟練が必要である。このため
最近では採血バツグに血液が所定量流入した時点
で採血管の採血針側を鉗子で止め、採血針を供血
者より抜き、５〜10mlの採血量に応じた真空試験
管に採血針を穿通した後、鉗子をゆるめ、真空試
験管内の陰圧により採血管内の抗凝固剤が混和さ
れていない血液を該真空試験管内に採血する方法
が行なわれている。 However, such a method requires complicated procedures and operations, and requires a certain level of skill. For this reason, recently, when a predetermined amount of blood has flowed into the blood collection bag, the blood collection needle side of the blood collection tube is stopped with forceps, the blood collection needle is removed from the donor, and the blood collection needle is inserted into a vacuum test tube corresponding to the amount of blood collected from 5 to 10 ml. After penetration, the forceps are loosened, and the negative pressure inside the vacuum test tube is used to collect blood unmixed with an anticoagulant from the blood collection tube into the vacuum test tube.
しかしこの方法では採血できる検査用血液は、
採血管内に入つている血液量に限られており、よ
り多くの検査用血液が必要な場合は別途注射器等
により採血しなければならないという不都合があ
る。 However, the test blood that can be collected using this method is
The amount of blood contained in the blood collection tube is limited, and if more blood is needed for testing, it is inconvenient that blood must be collected separately using a syringe or the like.

構成としたことにある。 The present invention has been devised to solve these conventional disadvantages, and its basic feature is that in a blood collection tube connected to a blood collection bag, the blood collection tube is provided with a connection mechanism for opening a flow path. A branch blood collection tube is connected through the branch blood collection tube, and a piercing needle is attached to the tip of the branch blood collection tube.The connection mechanism for opening the flow path is configured to insert a cylindrical body into the branch part of the branch blood collection tube, and attach a piercing needle to the tip of the branch blood collection tube. One end of the opening is closed with a small head via a thin wall portion, and the small head is breakable at the thin wall portion.

FIG. 2 shows an example of the connection mechanism, in which a branch tube 4 and a branch blood collection tube 5 are connected by a flexible connecting tube 7, and a connecting tube 8 is built into the connecting tube 7. be. This connecting tube 8 is made of synthetic resin, and has a thin wall portion 9 formed in the middle portion. When the small head 10 is pressed with a finger from the outside of the connecting tube 7, it will break at the thin wall portion 9, and the connecting tube 8 will break. is about to open.

のである。 Next, an example of the use of the present invention will be described. First, as in the conventional case, the blood collection needle 3 of the blood collection main tube 2 is punctured into the donor's vein, and a predetermined amount of blood is allowed to flow into the blood collection bag 1 through the blood collection main tube 2. At this point, the upper part of the branch tube 4 of the main blood collection tube 2 on the bag 1 side is stopped with forceps or the like. Next, when the communication mechanism 12 is opened by finger pressure, the blood from the donor naturally flows into the branch blood collection tube 5, and the necessary amount of blood is collected into an ordinary test tube (not shown). When blood is collected in a vacuum test tube, a predetermined amount of blood is collected by piercing the injection needle 6 through the sealed stopper of the test tube. Furthermore, if more blood for testing is required, temporarily stop the branch blood collection tube 5 with forceps.
After piercing a new test tube or vacuum test tube with the injection needle 6, the forceps are loosened and the required amount of blood is collected.

部を切断するものである。 After blood without an anticoagulant mixed in the test tube or vacuum test tube is thus collected using the branch blood collection tube 5, the branch blood collection tube 5 is fixed with forceps. Subsequently, the blood collection needle 3 is removed from the blood donor, the blood collection needle 3 is pierced into the vacuum test tube, and the forceps are loosened to allow blood not mixed with an anticoagulant to flow into the vacuum test tube. As a result, the inside of the blood collection main tube 2 is filled with blood mixed with anticoagulant, and in this state, the upper part of the bag 1 side of the branch pipe 4 of the blood collection main tube 2 is sealed with an aluminum ring, a knot, etc. This is to cut the lower part of the branch pipe 4.

れ、その実用性に優れた考案である。 According to the present invention described above, after blood is collected from a donor through a blood collection tube into a blood collection bag, the blood to be tested (anticoagulant mixed in (not blood)
The blood naturally flows into a branch blood collection tube due to blood pressure, and the blood can be collected into a test tube through a piercing needle. For this reason, the operation is easier compared to the conventional method of using the blood flowing into the blood collection main tube as test blood, and the required amount can be obtained by inserting the blood collection needle into the person collecting blood. This is a highly practical device that has the advantage of being able to continuously collect blood for testing.
