no. 1 Embodiment approach 〕

[0033] Such as figure 1 As shown, the blood transfusion system 10 according to the first embodiment of the present invention comprises a flexible tube 12 (tube structure) having a flow channel 14 inside to form a flow path 16 through which blood flows. The flow path 16 includes a blood collection path 18 (blood collection flow path) for collecting blood from a blood donor, and an administration path 20 (an administration flow path) for administering blood to a patient (blood transfusion recipient). The blood collection channel 18 and the administration channel 20 are respectively connected to a blood bag 22 that temporarily stores blood. It should be noted that the tube structure constituting the flow path 16 includes, in addition to the tube 12 , various tubular members through which the liquid can flow. For example, three-port connectors 30 , 40 , 42 , drip tube 48 , and the like described later also correspond to the tube structure.

[0034] In addition, the blood transfu...

no. 2 Embodiment approach 〕

[0073] The blood transfusion system 10A of the second embodiment of the present invention is as Figure 4 As shown, the difference from the blood transfusion system 10 of the first embodiment is that an introduction structure portion 74 that constructs the introduction portion 25 on the downstream side of the administration path 20 (downstream path 70 ) is integrally provided. It should be noted that in the following description, elements having the same configuration or function as those of the above-mentioned embodiment are given the same reference numerals, and detailed description thereof will be omitted.

[0074] Specifically, the introduction structure part 74 of the downstream path 70 is located downstream of the roller clamp 50 in the administration downstream tube 72 and includes a male closed-end connector 76 and the administration needle 54 (blood transfusion part: winged needle). It should be noted that the blood collection path 18 , the upstream path 60 , the firs...

Abstract

In a blood transfusion system (blood transfusion kit, blood transfusion kit for emergency blood transfusions, and method for using blood transfusion kit) (10), a flow channel (16) through which bloodflows is configured from a tube (12) having a flow path (14) in the interior thereof. The flow channel (16) includes: a first channel (80) that connects an upstream channel (60) and a downstream channel (70), the first channel (80) having a leukocyte removal filter (82) for removing leukocytes at an intermediate position along the flow path (14); and a second channel (90) that connects the upstream channel (60) and the downstream channel (70), the second channel (90) bypassing the leukocyte removal filter (82).

Description

technical field [0001] The present invention relates to a blood transfusion kit, a blood transfusion system, a blood transfusion kit for emergency blood transfusion, and a method of using the blood transfusion kit for transfusing blood to a blood transfusion object. Background technique [0002] In blood transfusion, leukocyte-depleted blood components (red blood cells, plasma, platelets, etc.) are usually administered to a patient (blood transfusion target). The reason for this is to suppress side effects of blood transfusion by removing white blood cells. However, in the case of emergency blood transfusion such as massive bleeding, whole blood provided by the blood donor may be transfused regardless of blood components. [0003] In addition, as a blood transfusion system used for emergency blood transfusion, for example, a rapid infusion set disclosed in Registered Utility Model No. 3005461 can be mentioned. The rapid infusion set has a pump part driven by external press...
