Original data	Initial concepts
I think the nurses of blood station are unprofessional. I am afraid that they can’t accurately find the location of the blood vessel.	A1-1 The nurses is unprofessional.; A1-2 Blood donors get hurt.
And I doubt whether the facilities of blood collection are clean. The facilities may be used many times or used without sterilization, so donors might catch infectious diseases. It is difficult to timely detect some infectious diseases. It’s too risky. I’d rather not donate blood.	A1-3 The equipment of blood collection is unsanitary.; A1-4 The equipment of blood collection is reused.; A1-5 The equipment of blood collection isn’t sterilized.
The environment of blood donation is also a problem. For example, the air in blood donation vehicles isn’t current and the seats of vehicles are dirty. In this environment, blood donors maybe catch infections from another.	A1-6 Catching some infections because of the equipment of blood collection.; A1-7 The air of blood donation vehicle is not current.; A1-8 The seats of blood donation vehicle is not cleaned frequently.; A1-9 Blood is sold to make profit.
Lastly, I am worried that blood isn’t used for medical treatment, but for making profit. It is said that blood stations staff benefit a lot through selling blood. The hospitals spend a lot buying blood from them, and these costs are paid by patients. Considering this possibility, I feel that I am cheated.	A1-10 Blood is sold to offer blood station staff high salary.; A1-11 The fees for blood transfusion is too high.; A1-12 Being cheated.
