Dana Lewis has been dealing with diabetes since her diagnosis with the insulin-destroying disease as a child.
戴娜·刘易斯小时候被诊断出患有糖尿病，它是一种能够破坏胰岛素的疾病，自此之后她一直与它抗争。
She constantly monitors her blood sugar levels and when they get too high or too low,
她经常监控血糖水平，当血糖过高或过低时，
an alarm warns her to take action, but that was not working for Lewis.
警报器会提醒她采取行动，但这对刘易斯不起作用。
In my case, because I'm such a good sleeper, I didn't wake up to this alarms
我的情况是，因为我睡觉睡得很死，所以我听不到报警器，
and so my blood sugar would just keep rising and rising and rising or keep dropping
所以我的血糖会不断上升，上升，或持续下降，
and it's more risky in the short term for the blood sugar to drop
短期内血糖持续降低会非常危险。
and because I live by myself, if I were to continue to sleep through the alarms and my blood sugar kept dropping,
因为我自己一个人生活，如果警报叫不醒我，与此同时我的血糖持续下降，
there's some bad outcomes that can happen which include going into a coma.
那么结果可能会很糟糕，我可能会进入昏迷状态。
Wanting to avoid that, Lewis along with some other software developers hacked into her glucose monitor to improve the alarm,
为了避免这种情况，刘易斯和其他一些软件开发人员入侵了她的血糖监测器，以改善警报器，
then she wrote an algorithm that does most of the work she was doing herself.
之后她编写了一套计算机程序，让她来代替自己的大部分工作。
Information comes in from each of the medical devices to a computer.
每一部医疗设备的信息将传送到电脑中。
It runs the math itself and then it says, okay, take action
它会自行计算，然后发出命令，采取行动，
and it's able to close the loop by sending those commands back to the insulin pump to make the insulin dosing adjustment.
这些命令将返回到胰岛素泵，使回路关闭，从而调整胰岛素剂量。
Hacking into a potentially life-saving medical device clearly is not recommended, but Lewis and other people who suffer from diabetes,
我们显然不推荐侵入可以挽救生命的医疗设备，但对于刘易斯和其他患者来说，
a disease that destroys the ability to process sugar say they were tired of waiting for health agencies to get new tech on the market.
他们已经厌倦了等待卫生机构推出新技术，这种疾病可以破坏人体的糖代谢。
When we first started on this project, diabetes tech was taking around four to five years to go through
当我们第一次开始这个项目的时候，糖尿病技术需要大约四到五年的时间才能通过
FDA approvals to get into the hands and have it be commercialized and get into the hands of type one diabetics.
美国食品及药品管理局批准，之后上市，随后1型糖尿病患者才能买到。
So Lewis posted her algorithm on the web and allowed anyone to work on her code and make improvements, process called open source coding.
因此，刘易斯将她的程序发布到网上，允许所有人使用她的编码，这种程序叫作开源代码。
That decision has already resulted in improvements like making the system compatible with smartphones and watches.
这一程序已经得到了发展，比如让系统和智能手机，手表相兼容。
We have a lot, we can still do in terms of optimizing the hardware and also optimizing the software and the algorithms that were able to use.
我们仍然可以继续优化硬件，软件还有程序。
I've been able to switch from having to bolus for meals and give myself a certain amount of insulin for meals
我之前需要在用餐前注射一定量的胰岛素，
and now being able to say just I'm eating, please dose my insulin for me.
现在是我要用餐，请给我注射胰岛素。
An estimated 415 million people around the world suffer from type 1 diabetes.
全球1型糖尿病患者数量预计在4.15亿人。
