现今的血液供给都是由人们自愿捐赠的,因此来源并不能始终保证。这样的血液,在安全性和存储上也存在一定问题。有没有什么办法可以保证血液供应的百分百充足与安全?科学家为此从17世纪起就开始了持续的努力在大多数的发达国家,病人们不用担心输血过程中的安全问题。但在现实中,要保证一个稳定、不受污染的供体血源则不易办到。那么是否有办法一劳永逸地确保充足、安全的血液供应呢?如今的血液供给,往往是由人们志愿捐赠的,因而存在可能携带HIV病毒及其他传染性病菌的风险。同时供体血液必须冷冻存储,并且只有28天的保质期限。这导致人们对血液污染的担忧,也大大影响了军队对持久血液供给的浓厚兴趣,于是血液合成替代品研究长期成为医学界的热门。使用血液替代品的概念源自17世纪,如今这一课题
Today’s blood supply is donated by people voluntarily, so the source can not always be guaranteed. Such blood has some problems in terms of safety and storage. Is there any way to ensure adequate and safe blood supply? Scientists began continuous efforts from the 17th century. In most developed countries, patients do not have to worry about the safety of transfusions. However, in reality, it is not easy to ensure a stable and uncontaminated donor’s blood supply. Is there any way to ensure an adequate and safe blood supply once and for all? Today’s blood supply, often donated by people voluntarily, poses the risk of carrying the HIV virus and other infectious germs. At the same time donor blood must be stored frozen, and only 28 days shelf life. This led to people’s concern about blood contamination, but also greatly affected the military’s strong interest in long-lasting blood supply, so the study of alternative blood products has long become the medical profession’s hot. The concept of using blood substitutes stems from the seventeenth century, the subject of today
