Definitions
- the present invention relates to a test blood container that collects (stores) initial blood for testing and a blood collection device that includes the test blood container.
- a blood collection device includes a venipuncture needle, a donor bag that stores blood collected through the venipuncture needle, and a plastic that connects the venipuncture needle and the donor bag.
- a pipe, a pipe segment branched from the middle of the plastic pipe, and a container (test blood container) communicating with the plastic pipe through the pipe segment are provided.
- the blood collection device of Patent Document 1 before blood is collected (stored) from a donor (donor) in a donor bag, that is, before the main blood is collected, an inlet disposed at the lower part of the blood container for testing. From the port, the initial blood of the donor is collected (inflow) into the internal chamber of the test blood container. The collected (stored) initial blood is collected (outflowed) into a blood sampling vial communicating with an outlet port disposed at the upper part of the test blood container and used for various tests.
- the blood collection device of Patent Document 1 has an advantage that initial blood used for various tests can be easily collected (stored). In addition, even if bacteria that are present in the skin or under the skin are mixed into the blood at the time of blood collection, the blood contaminated with bacteria can be removed to the first blood bag as the first blood, so the blood collected (stored) in the donor bag There is an advantage that bacterial contamination can be prevented.
- the operator starts collecting the first blood in the test blood container, and the fact that a predetermined amount of the first blood has been collected in the container indicates that After visually checking the surface height, the clamp installed in the piping segment is closed to stop (complete) the flow of the initial blood flow into the blood container for testing.
- the timing of closing the clamp varies depending on the operator, and the amount of the initial blood collected (stored) in the test blood container Variations may occur, resulting in overcollection and a lack of minimum collection. In the case of excessive collection, the health of the donor and residual blood loss occur.
- the minimum collection amount cannot be ensured, various tests cannot be performed using primary blood, and the safety of blood collected in the donor bag cannot be guaranteed.

- the flow path in the sealing member 59 is opened by breaking the solid front end portion (not shown) of the sealing member 59.
- the blood collection channel of the tube 58 is opened, and the tube 57 and the tube 58 communicate with each other.
- the collected blood flows into the blood collection bag 52 through the tube 57, the branch connector 56, the sealing member 59, and the tube 58.
- the initial blood collected (stored) in the test blood container 1 is inspected for the decompression blood collection tube 71 and the like. Sampling to the instrument.
- the reduced pressure blood collection tube 71 is inserted into the blood collection unit 21 (holder 22) and pushed to the innermost part of the holder 22, and the hollow needle 24 is moved to the blood collection tube of the reduced pressure blood collection tube 71.
- the rubber plug 73 inserted in the main body 72 is punctured and penetrated.
- the initial blood stored in the test blood container 1 is sucked into the blood collection tube main body 72 and sampled.
- the vacuum blood collection tube 71 is removed from the blood collection unit 21 (holder 22). Note that this operation is repeated when sampling the first blood flow into a plurality of decompression blood collection tubes 71.
- the blood collection needle 53 is withdrawn from the donor's vein, and if necessary, using a tube sealer or the like.
- the tube 58 and the branch tube 60 are closed and sealed. Thereafter, the test blood container 1 and the blood collection needle 53 are separated. Thereby, the blood collection bag 52 in which the blood from which the initial blood has been removed is stored is obtained.
- the blood stored in the blood collection bag 52 is passed through a leukocyte removal filter to separate white blood cells and platelets, and the remaining blood components are collected in a collection bag, and the blood collection bag 52 and the leukocyte removal filter are removed. Separate. Thereafter, the blood in the collection bag is centrifuged to separate the red blood cell layer and the plasma layer. After transferring the plasma to the plasma bag, the red blood cell storage solution in the red blood cell storage solution bag is added to the concentrated red blood cells remaining in the recovery bag. Add and mix.
- a blood bag is used as a storage part.
- a blood separator for example, a centrifugal separator or a membrane separator
- the blood collection device is not limited to the blood bag system, and may be a blood component collection circuit.

Abstract
Description
図1に示すように、検査用血液容器1は、容器本体部2と、血液流入ポート5と、血液流出ポート6と、排気部7とを備え、その排気部7には遮断部8が配置されている。
図1に示すように、検査用血液容器1は、前記構成に加えて、血液流出ポート6に連通して、容器本体部2に貯留された初流血を減圧採血管71(検査器具)に採取させる採血部21をさらに備えることが好ましい。
図3に示すように、採血器具51(血液バッグシステム)は、採血針53と、採血針53を介して採取された血液を収納する採血バッグ52(貯留部、血液バッグ)と、採血針53と採血バッグ52とを連結する採血ラインと、採血ラインの途中から分岐する分岐ラインと、分岐ラインを介して、採血ラインと連通する初流血を採取(貯留)する検査用血液容器1とを備えている。以下、各構成について説明する。なお、検査用血液容器1については前記のとおりであるので、説明を省略する。
まず、図3に示すように、採血器具51では、検査用血液容器1の遮断部8(クランプ)を開放状態とし、血液流入ポート5の流路が開放された状態とする。そして、チューブ58の採血流路は、封止部材59により閉塞した状態となっている。なお、検査用血液容器1は、スタンド等に吊り下げて下垂状態とし、排気部7が容器本体部2の上端に位置するようにする。また、検査用血液容器1を容器表面が作業台等に接触するように容器全体を水平に載置した状態(横置き状態)にしてもよい(図示せず)。
この場合、封止部材59の中実先端部(図示せず)を破断することによって、封止部材59内の流路を開通させる。この操作により、チューブ58の採血流路が開通状態となり、チューブ57とチューブ58が連通する。これにより、採血された血液が、チューブ57、分岐コネクタ56、封止部材59およびチューブ58を介して、採血バッグ52内に流入する。
