This is an equipment graveyard.
0
12818
2222
这是一座设备的墓地。
00:15
It's a typical final resting place
1
15064
2228
是为非洲医院中的
00:17
for medical equipment from hospitals in Africa.
2
17316
2786
医疗器械提供的 一个典型的最终归宿地。
00:20
Now, why is this?
3
20720
1415
为什么会有这样一番景象?
00:22
Most of the medical devices used in Africa are imported,
4
22641
4187
大多数在非洲使用的 医疗设备都是进口的,
00:26
and quite often, they're not suitable for local conditions.
5
26852
3644
很多情况下, 它们并不适用于当地的条件。
00:31
They may require trained staff
6
31095
3250
它们可能要求 训练有素的医护人员,
00:34
that aren't available to operate and maintain and repair them;
7
34369
3655
然而现实中这些人并没有能力 去操作、保养或者维修这些设备;
00:38
they may not be able to withstand high temperatures and humidity;
8
38739
3769
这些设备可能无法 承受高温和潮湿的环境;
00:42
and they usually require a constant and reliable supply of electricity.
9
42532
4462
并且它们需要持续 可靠的供给电源。
00:48
An example of a medical device
10
48104
2099
一个医疗设备在某个时间
00:50
that may have ended up in an equipment graveyard at some point
11
50227
4202
可能被弃置于设备墓地的例子是,
00:55
is an ultrasound monitor to track the heart rate of unborn babies.
12
55039
4570
一个用于实时跟踪胎儿 心跳的超声波监测仪。
01:00
This is the standard of care in rich countries.
13
60447
3431
在发达国家,它是 孕检的标准配置。
01:03
In low-resource settings, the standard of care is often
14
63902
3746
然而在低配置的环境中, 孕检的标准常常是
01:07
a midwife listening to the baby's heart rate
15
67672
3209
一位助产士用角状听诊器
01:10
through a horn.
16
70905
1154
去听宝宝的心跳。
01:12
Now, this approach has been around for more than a century.
17
72689
3971
至今,这种方法已经 沿用了超过一个世纪。
01:16
It's very much dependent on the skill and the experience of the midwife.
18
76684
4485
这种方法很依赖于 助产士的技术和经验。
01:22
Two young inventors from Uganda
19
82528
2805
几年前,两位年轻的乌干达发明家
01:25
visited an antenatal clinic at a local hospital a few years ago,
20
85357
4532
来到了一家当地医院的 附属产前诊所,
01:29
when they were students in information technology.
21
89913
2832
他们当时还是信息技术专业的学生。
01:33
They noticed that quite often,
22
93425
2668
他们注意到,很多情况下,
01:36
the midwife was not able to hear any heart rate
23
96117
3084
当那里的助产士 尝试用角状听诊器去听的时候,
01:39
when trying to listen to it through this horn.
24
99225
2688
其实根本听不到任何心跳的声音。
01:42
So they invented their own fetal heart rate monitor.
25
102665
4537
因此,他们发明了 自己的一套胎儿心跳监视器。
01:48
They adapted the horn and connected it to a smartphone.
26
108156
4599
他们改造了角状听诊器, 并将它和智能手机相连接。
01:52
An app on the smartphone records the heart rate, analyzes it
27
112779
4493
在手机上有一个应用 可实时记录心跳、分析数据,
01:57
and provides the midwife with a range of information
28
117296
2904
并且提供给助产士 一系列关于宝宝
02:00
on the status of the baby.
29
120224
1755
当前状况的信息。
02:03
These inventors --
30
123529
1312
这两位发明家——
02:04
(Applause)
31
124865
1222
(鼓掌)
02:06
are called Aaron Tushabe and Joshua Okello.
32
126111
3103
是亚伦·杜尚别(Aaron Tushabe) 和约书亚·奥凯洛(Joshua Okello)。
02:10
Another inventor, Tendekayi Katsiga,
33
130591
3363
另一位发明家, 滕德卡伊·卡特西戈(Tendekayi Katsiga),
02:14
was working for an NGO in Botswana that manufactured hearing aids.
34
134739
5588
是博兹瓦纳一个民间组织的成员, 这个组织是制造助听设备的。
02:20
Now, he noticed that these hearing aids needed batteries
35
140738
5097
当时,他注意到这些助听设备
02:25
that needed replacement,
36
145859
1197
需要经常更换电池,
02:27
very often at a cost that was not affordable
37
147080
2634
而这样的花费是许多使用者
02:29
for most of the users that he knew.
38
149738
2102
负担不起的。
02:32
In response, and being an engineer, Tendekayi invented
39
152151
5089
为此,作为一名工程师的滕德卡伊
02:37
a solar-powered battery charger with rechargeable batteries,
40
157264
3610
针对这些助听设备, 发明了一款带可充电电池的
02:40
that could be used in these hearing aids.
41
160898
2319
太阳能电池充电器。
02:43
He cofounded a company called Deaftronics,
42
163625
3902
他与别人共同创立了一家名叫 “Deaftronics”的公司。
02:47
which now manufactures the Solar Ear,
43
167551
2660
这家公司如今 在生产“太阳能耳(Solar Ear)”,
02:50
which is a hearing aid powered by his invention.
44
170727
3249
这是一种由他发明的电池 供能的助听装置。
02:55
My colleague, Sudesh Sivarasu, invented a smart glove
45
175829
5237
我有一个同事名叫 苏德什·思沃苏(Sudesh Sivarasu),
他发明了智能手套来帮助麻风病人。
03:01
for people who have suffered from leprosy.
46
181090
2166
03:03
Even though their disease may have been cured,
47
183799
3005
即使他们的疾病可以被治愈,
03:06
the resulting nerve damage will have left many of them
48
186828
3156
但是麻风对神经的伤害会导致
03:10
without a sense of touch in their hands.
49
190008
2538
他们手部的触觉丧失。
03:12
This puts them at risk of injury.
50
192570
2058
这会使他们很容易受伤。
03:16
The glove has sensors to detect temperature and pressure
51
196017
4025
这款手套拥有温度和压力传感器,
03:20
and warn the user.
52
200066
1381
可以帮助使用者(远离潜在的伤害)。
03:22
It effectively serves as an artificial sense of touch
53
202581
3509
它有效的提供了 一种人造的触觉感受,
03:26
and prevents injury.
54
206114
1466
从而避免使用者受伤。
03:28
Sudesh invented this glove after observing former leprosy patients
55
208032
4689
苏德什在仔细观察了之前的 麻风病人每天要做的事情,
03:32
as they carried out their day-to-day activities,
56
212745
2946
而且在得知这些病人
03:35
and he learned about the risks and the hazards in their environment.
57
215715
3589
时刻面临受伤的风险之后, 发明了这款手套。
03:41
Now, the inventors that I've mentioned
58
221774
2180
上述提到的这些发明者
03:43
integrated engineering with healthcare.
59
223978
2679
结合了电子工程和健康管理的知识。
03:47
This is what biomedical engineers do.
60
227260
2235
这也是许多生物医学 工程师做的事情。
03:50
At the University of Cape Town,
61
230558
1905
在开普敦大学,
03:52
we run a course called Health Innovation and Design.
62
232487
3157
我们开设了一门名叫 “健康的创新设计”的课程。
03:55
It's taken by many of our graduate students in biomedical engineering.
63
235668
3947
主修这门课程的是 生物医学工程的研究生。
04:00
The aim of the course is to introduce these students
64
240106
3597
这门课程的目标是 为学生们介绍
04:03
to the philosophy of the design world.
65
243727
2555
设计世界中的哲学。
04:06
The students are encouraged to engage with communities
66
246306
3021
他们鼓励学生加入一些团体,
04:09
as they search for solutions to health-related problems.
67
249351
3243
寻找与健康相关问题的解决方案。
04:13
One of the communities that we work with is a group of elderly people
68
253055
3269
其中一个我们工作的社区是
04:16
in Cape Town.
69
256348
1224
一个开普敦的老年团体。
04:17
A recent class project had the task of addressing hearing loss
70
257596
4140
一个最近的课程项目任务是
04:21
in these elderly people.
71
261760
1450
去登记丧失听力的老人。
04:23
The students, many of them being engineers,
72
263886
2772
这些学生,大部分是工程师,
04:26
set out believing that they would design a better hearing aid.
73
266682
4851
他们很自信自己 会设计出更好的助听器。
04:31
They spent time with the elderly,
74
271557
1608
他们跟那些老人相处了一段时间,
04:33
chatted to their healthcare providers and their caregivers.
75
273189
3248
与老人们的卫生保健人员 和看护人聊天。
04:37
They soon realized that, actually, adequate hearing aids already existed,
76
277039
5114
他们不久就意识到, 事实上,合适的助听器早已存在,
04:42
but many of the elderly who needed them and had access to them
77
282177
3996
但是很多需要并使用这些设备的老人,
04:46
didn't have them.
78
286197
1413
却并不拥有这些设备。
04:47
And many of those who had hearing aids
79
287954
2112
并且很多有助听器的人,
04:50
wouldn't wear them.
80
290090
1233
却不会佩戴它们。
04:52
The students realized
81
292321
1990
这些学生意识到,
04:54
that many of these elderly people were in denial of their hearing loss.
82
294335
3937
很多的老年人拒绝接受 他们有听力障碍的现状。
04:58
There's a stigma attached to wearing a hearing aid.
83
298296
2500
戴助听器会与耻辱联系到一起。
05:01
They also discovered that the environment in which these elderly people lived
84
301757
4758
他们还发现这些 老年人居住的环境,
05:06
did not accommodate their hearing loss.
85
306539
2023
十分不利于有听力障碍的人。
05:08
For example, their homes and their community center
86
308586
3781
比如说,他们的家和社区中心
05:12
were filled with echoes that interfered with their hearing.
87
312391
3068
充斥着干扰他们听力的回声。
05:15
So instead of developing and designing a new and better hearing aid,
88
315999
5108
因此,这些学生把工作重心从开发 并设计出全新且更好的助听设备,
05:21
the students did an audit of the environment,
89
321131
2683
改为在该环境中进行一项调查,
05:23
with a view to improving the acoustics.
90
323838
2399
以此制定出提高传声效果的计划。
05:27
They also devised a campaign to raise awareness of hearing loss
91
327196
3834
他们还设计出一个活动计划, 来提高人们对于听力丧失群体的关注,
05:31
and to counter the stigma attached to wearing a hearing aid.
92
331054
3576
从而消除戴助听器与耻辱之间的关系。
05:35
Now, this often happens when one pays attention to the user --
93
335603
3384
当一个人开始关注使用者, 这种情况常常发生——
这里是指那些老年人——
05:39
in this case, the elderly --
94
339011
1650
05:40
and their needs and their context.
95
340685
1965
他们的需要和环境。
05:43
One often has to move away from the focus of technology
96
343219
2846
一个人常常不得不 离开科技的聚光灯,
05:46
and reformulate the problem.
97
346089
1838
纠正这个问题。
05:48
This approach to understanding a problem through listening and engaging
98
348861
3977
去理解一个问题的方法是 去倾听并且参与它,
05:52
is not new,
99
352862
1228
虽然这个方法已经是老生常谈,
05:54
but it often isn't followed by engineers,
100
354601
2612
但是它并不经常被那些
05:57
who are intent on developing technology.
101
357237
3110
一心想发展科技的工程师们所采用。
06:01
One of our students has a background in software engineering.
102
361704
3448
我们有一个学生 有软件工程方面的背景。
06:05
He had often created products for clients
103
365176
2677
他曾经为顾客发明产品,
06:07
that the client ultimately did not like.
104
367877
2389
但那些产品顾客根本就不喜欢。
06:10
When a client would reject a product,
105
370902
2177
当有顾客想去 拒绝一件产品的时候,
06:13
it was common at his company
106
373103
1885
他的公司经常表明的是
06:15
to proclaim that the client just didn't know what they wanted.
107
375012
3708
顾客只是不知道 他们自己想要的是什么。
06:19
Having completed the course, the student fed back to us
108
379384
3562
在完成课程学习之后, 那个学生给我们的反馈是,
06:22
that he now realized that it was he who hadn't understood
109
382970
3198
现在他意识到 不知道顾客想要什么的
06:26
what the client wanted.
110
386192
1421
是他自己。
06:28
Another student gave us feedback
111
388254
2573
另一个学生给我们的反馈是,
06:30
that she had learned to design with empathy,
112
390851
2468
她曾经怀揣着同理心学设计,
06:33
as opposed to designing for functionality,
113
393343
2990
反对单纯的实用性设计,
06:36
which is what her engineering education had taught her.
114
396357
2731
这是她的专业教育教给她的。
06:39
So what all of this illustrates is that we're often blinded to real needs
115
399830
4132
我上述所有的举例说明了 我们在盲目追求科技过程中
06:43
in our pursuit of technology.
116
403986
1593
忽视了真正的需求。
06:45
But we need technology.
117
405936
1581
但是我们需要科技。
06:47
We need hearing aids. We need fetal heart rate monitors.
118
407541
2969
我们需要助听器, 我们需要胎儿心跳监视器。
06:51
So how do we create more medical device success stories from Africa?
119
411385
4783
那么我们如何去创造更多的 医疗设备在非洲成功的案例呢?
06:56
How do we create more inventors,
120
416967
1978
我们如何去培养出更多的发明者,
06:58
rather than relying on a few exceptional individuals
121
418969
3247
而不是依赖于 一小部分有杰出能力的人,
07:02
who are able to perceive real needs
122
422240
2108
那些有能力去感知 真正被需要的东西,
07:04
and respond in ways that work?
123
424372
1842
并且在他们的工作中做出对策的人?
07:06
Well, we focus on needs and people and context.
124
426718
3460
我们关注具体的需求、人群和环境。
07:10
"But this is obvious," you might say,
125
430497
1832
“但这不是很明显的吗,”你可能会说,
07:12
"Of course context is important."
126
432353
2278
”环境当然是很重要的因素啊。”
07:15
But Africa is a diverse continent,
127
435486
2408
但是非洲是一块多元化的陆地,
07:17
with vast disparities in health and wealth and income and education.
128
437918
4871
在健康、财富、收入 和教育方面有很大的差异。
07:22
If we assume that our engineers and inventors already know enough
129
442813
5027
如果我们假定我们的 工程师和发明家足够了解
07:27
about the different African contexts
130
447864
2586
非洲多元化的环境特点,
07:30
to be able to solve the problems of our different communities
131
450474
3841
从而有能力去解决不同社区
07:34
and our most marginalized communities,
132
454339
1939
和我们最边缘化的社区问题,
07:36
then we might get it wrong.
133
456302
1448
我们就有可能会向错误的方向发展。
07:38
But then, if we on the African continent
134
458907
2595
但是,如果我们在非洲大陆上
07:41
don't necessarily know enough about it,
135
461526
3272
得知了超出计划的环境信息,
07:44
then perhaps anybody with the right level of skill and commitment could fly in,
136
464822
4130
然后也许有一定技术水平和 责任感的人都会飞到非洲,
07:48
spend some time listening and engaging
137
468976
2469
花一些时间来聆听、参与,
07:51
and fly out knowing enough to invent for Africa.
138
471469
3257
并在了解了足够信息之后 回到自己的国家开始为非洲打造新发明。
07:55
But understanding context is not about a superficial interaction.
139
475953
4315
但是对非洲环境的理解 并不仅限于浅层次的互动。
08:00
It's about deep engagement
140
480292
1960
这是一种深度的参与,
08:02
and an immersion in the realities and the complexities of our context.
141
482276
4638
需要深入了解现实情况 以及环境的复杂性。
08:07
And we in Africa are already immersed.
142
487877
3142
我们早就深入了非洲的环境之中。
08:11
We already have a strong and rich base of knowledge
143
491522
3673
我们早已拥有一个 强大且丰富的知识储备,
08:15
from which to start finding solutions to our own problems.
144
495219
3678
并且开始寻找我们 自身问题的解决方案。
08:19
So let's not rely too much on others
145
499873
3016
所以,我们不需要过分依赖他人,
08:23
when we live on a continent that is filled with untapped talent.
146
503548
4094
特别是当我们正身处一个 拥有众多潜力人才的陆地上。
08:28
Thank you.
147
508124
1186
谢谢。
08:29
(Applause)
