WEBVTT Kind: captions Language: en 00:00:00.080 --> 00:00:04.840 So I’m Sara Rampazzi and I'm working for the University of Michigan but I am also a 00:00:04.840 --> 00:00:07.589 professor of University of Florida. 00:00:07.589 --> 00:00:13.740 And this is the RAPID Science of using wireless technology for quickly verifiable decontamination 00:00:13.740 --> 00:00:15.730 procedure for I-95 masks. 00:00:15.730 --> 00:00:24.220 This is a joint effort between me and Professor Kevin Fu as part of the consortium and N95DECOM. 00:00:24.220 --> 00:00:32.900 So, as you can see, in the past month, we face a severe shortage of PPE and mask. 00:00:32.900 --> 00:00:39.790 And healthcare workers were forced to use these masks when treated COVID patients. 00:00:39.790 --> 00:00:42.350 And all around the world we see this shortage. 00:00:42.350 --> 00:00:47.730 So the CDC has developed different crisis strategies for dealing with the shortage and 00:00:47.730 --> 00:00:54.480 one of them was implemented limited reuse of N-95 masks after verifiable decontamination 00:00:54.480 --> 00:00:56.060 procedures. 00:00:56.060 --> 00:01:01.790 So our research project aimed to protect these frontline healthcare workers by lowering the 00:01:01.790 --> 00:01:05.530 risk of infection from reuse N-95 mask. 00:01:05.530 --> 00:01:12.170 So we develop reliable wireless sensor technology and procedures for each base decontamination 00:01:12.170 --> 00:01:13.170 process. 00:01:13.170 --> 00:01:18.490 It is easily deployable, low power, low cost, scalable, and secure to be used in healthcare 00:01:18.490 --> 00:01:24.030 facilities around the world under resources and under N-95 mask shortage. 00:01:24.030 --> 00:01:28.290 But why [is] decontaminate this mask so hard? 00:01:28.290 --> 00:01:33.680 Because it has the word say - disposable masks are not designed to be used multiple times. 00:01:33.680 --> 00:01:39.080 So you don't have only to ensure how - the wait coronavirus [de]activation, but you have 00:01:39.080 --> 00:01:44.540 also to avoid degradation of the filtration performance and also degradation of the mask 00:01:44.540 --> 00:01:47.500 sealing and fitting for the wear. 00:01:47.500 --> 00:01:53.610 And also avoid cross contamination of other pathogens like bacterium, for example. 00:01:53.610 --> 00:02:00.960 So the CDC has identified the moist heat as one of the most easy deploy - deployment and 00:02:00.960 --> 00:02:04.549 most cheaper techniques for the decontamination. 00:02:04.549 --> 00:02:05.560 Why does this happen? 00:02:05.560 --> 00:02:10.132 Because the temperature and humidity [inaudible] are required for this. 00:02:10.132 --> 00:02:15.390 The contamination is suitable for heating devices already present in hospitals. 00:02:15.390 --> 00:02:22.920 So this cheap technique can be used also to be able to use this mask up to five times. 00:02:22.920 --> 00:02:29.220 So how our project is tackling the challenges to have widely deployed this [technique] in 00:02:29.220 --> 00:02:35.780 hospital, for example, where the lack of standard procedure of this type of decontamination 00:02:35.780 --> 00:02:40.650 or the lack of specialized equipment, for example, commercially, heating device can 00:02:40.650 --> 00:02:45.579 have humidity and not uniform leakage. 00:02:45.579 --> 00:02:50.450 And each mask requires stable decontamination condition. 00:02:50.450 --> 00:02:57.190 So it's essential that you constantly monitoring heat and humidity level for each mask. 00:02:57.190 --> 00:03:04.650 So, the current results that we have, we develop our first prototype- 00:03:04.650 --> 00:03:11.500 But it is this platform that can be used for monitoring heat - the temperature and humidity 00:03:11.500 --> 00:03:17.110 level of each mask and it is a wireless system with multiple sensor nodes, one for each mask, 00:03:17.110 --> 00:03:22.800 with a high temperature resistance sensor and with limited energy consumption. 00:03:22.800 --> 00:03:29.560 This is a cheap and [inaudible] consumer device technology that can be implemented on combating 00:03:29.560 --> 00:03:31.730 heating systems. 00:03:31.730 --> 00:03:38.349 And everything is monitored by a smartphone app for automated control. 00:03:38.349 --> 00:03:43.810 And also you can raise an alarm for like, [making] aware the nurse, in case of a change 00:03:43.810 --> 00:03:46.599 of environmental condition. 00:03:46.599 --> 00:03:52.129 So this is the team that is, like during this month, is working on a joint effort between 00:03:52.129 --> 00:03:56.930 the University of Michigan or the University of Florida, Northwestern University. 00:03:56.930 --> 00:04:03.220 So we are working to optimize this system, for example, adding energy investing on RFID 00:04:03.220 --> 00:04:10.910 technology to be able to monitor the things and lowering the power consumption. 00:04:10.910 --> 00:04:16.079 And our goal is deployment and testing in the clinical settings and also integrating 00:04:16.079 --> 00:04:23.199 this system in, like, a common operating procedure in hospitals. 00:04:23.199 --> 00:04:26.160 And then we will global disseminate the results. 00:04:26.160 --> 00:04:30.080 We identified DECOM consortium. 00:04:30.080 --> 00:04:33.180 So, thank you for the attention. 00:04:33.180 --> 00:04:41.259 This is my email [srampazzi@ufl.edu] so you can reach me for the other information. 00:04:41.259 --> 00:04:45.180 And this is the website [https://spqrlab1.github.io/N95deconProject] so you can see all the updates on the - on 00:04:45.180 --> 00:04:51.830 the project and visit the N-95 home for other mask decontamination information. 00:04:51.830 --> 00:04:52.330 Thank you!
