Please do not lock the meeting as proposed as many people are on unreliable internet.
Farid HAFEZ
36:20
What are the correct standards required?
Pontsho Maruping
40:16
You can find all the template here: https://www.sarao.ac.za/media-releases/sarao-mandated-to-manage-the-production-of-respiratory-ventilators/
Wessel Brits
41:48
This reference design is for CPAP and not BIPAP correct?
Dr Jean-Patrick Leger
42:10
Please be so kind as to provide some of the best video links on the design - Dr Kusel mentioned these in his presentation
Lance Michell
43:09
This is a CPAP system not NIV
Johan Pretorius
46:08
Humidification?
abam
48:20
alarms?
Clifford
50:32
Does this allow for prone positioning of patient? There seems to be consensus that prone positioning is quite important.
Rob Sterling
50:42
has anybody form the team looked @ the opensource designs
Andrea Steyn
51:41
Regarding SAHPRA registration. Will there be any assistance to speed up the process?
Jaco Botha
52:10
Are the details of the reference design available for licensing by manufacturers?
Harry Teifel
52:35
Please confirm: The focus is thus on the patient and not similar solutions for protection of medical personnel?
Drako and James
53:00
what about designs which allow for manual operation - without electrical source?
Rian Strydom
53:03
will oxygen concentrators be con sidered for off network operation
Clifford
53:10
AFAIK, CPAP/BIPAP requires synchronisation with patient breathing? This is not a regular CPAP.
Andrea Steyn
53:15
Can a company submit more than one concept? Can we then submit two excel sheet for each concept?
Hendrik Nel
53:21
Does this not have a risk for CO2 levels rising in the hood?
Dipak
53:47
There being no need for an ambient air filter…. is this because the patient is ALREADY infected? Susceptibility for other infections to intrude, not a concern?
Clifford
54:44
O2 sensing in patient? Pulse oximeter is typically not good enough for this, afaik?
Johan’s iPhone
54:59
Pollution/viral shedding of surroundings!! see guidlines of the WHO and CDC re so called non-invasive ventilation.
Thamsanqa MAQUBELA
55:03
does this also require mass use of the ventilator for use at make shift hospitals, clinics and for home use? this will be a key requirement for ease of use and practicality.
Dipak
55:06
Which parts/components are to be regarded as bio hazard disposal for each individual use?
Farid HAFEZ
55:18
COVID-19 is highly infectious, removing the hood for food or drink compromises the caregiver
Johan’s iPhone
55:35
this is non a ventilator its a cpap device
Simone Rudolph-Shortt
55:54
HI, is there a design plan and documentation todate?
Sibu Mvana
55:59
Is there a different criteria for low cost positive air pressure devices?
Wayne Banfield
56:19
Why are not using CPAP systems that are currently available for the treatment of Sleep Apnea
Simone Rudolph-Shortt
56:23
There is NO product registration .. the company need to be licemced
George Gericke
56:33
How big a concern is ventilator barotrauma? How sedated is the intended patient
Johan’s iPhone
56:39
Nursing/healthcare exposure not in line with international guidlines with such a system
Geoff Tugwell
57:16
How prevalent is oxygen supply in hospitals.
N.Human
57:36
If deployed in field hospital/temporary medical care facilities, what are the power backup requirements. obviously there will be accessibility issues in rural communities and densely populated areas. will the 30min specification be adequate?
Dipak
58:21
This device assumes that patient is able to breath himself/herself; no positive pressured to “pressure fill” lung alveoli?
Simone Rudolph-Shortt
58:26
what is the plan for validation of the product / s … is there a clinical protocol yet?
Regardt
59:20
Specification document references "National Ventilator Project Execution Plan", SSA4003-0009-001. Can we get access to this document?
Johan’s iPhone
59:41
non invasive ventilation implies an active action from the device, by definition a cpap machine
Farid HAFEZ
01:00:41
At which stage of the decease as specified by WHO and CDC is this design expected to be used?
Johan’s iPhone
01:00:48
if a patient needs cpap they will most probably continue to get sicker and wil need more support than just cpap
Simone Rudolph-Shortt
01:00:56
I hear a lot of questions - Has a risk assessment for the product / s been populated which should be done before design planning and initiation as inputs and outputs would define the design plan and activities
Lance Michell
01:01:05
I suggest an alarm to alert pressure falling to zero. Could be a simple battery operated system
Wouter Gerber
01:01:19
Will SARAO be doing the systems engineering?
Johan’s iPhone
01:01:33
what will happen to a patient that does not cope on the said aystem and needs more intensive care?
Elizabeth
01:01:39
http://www.thedti.gov.za/news2020/CFP_NVP.pdf
Elizabeth
01:01:46
SSA4003-0009-001
Marnus Van Niekerk
01:01:49
So this is purely constant pressure? No active ventilation?
Wouter Gerber
01:01:52
if so please provide ICY between components
Jan van Loggerenberg
01:02:13
Aerosud does not have medical equipment expertise but we do have great engineering, industrialisation, production, baseline management (PLM) etc. experience in a highly regulated (commercial aerospace) industry. How can we best contribute? Anybody want to partner with us?
Michael Cousins
01:02:27
Have we identified potential local suppliers of medical grade materials? In my experience, getting medical grade materials in SA is very difficult if not impossible.
Regardt
01:02:37
@Elizabeth, page cannot be found
Simone Rudolph-Shortt
01:03:10
suggest you copy paste the chat before you end so that you have a record
Juan Strauss
01:03:51
the MIT design caters for battery backup- ie. having the device portable. is this not more feasible than the complexities associated with creating a proper seal with the hoody concept in terms of ensuring positive inhale pressure? will the hoody achieve appropriate pressure during inhale?
Farid HAFEZ
01:03:52
The mask has to be removed for the patient to eat and drink!
Tim
01:03:54
Why would an automated design AMUbag solution be insufficient for purpose?
Elizabeth
01:03:54
http://www.thedti.gov.za/news2020/CFP_NVP.pdf
Eleanor
01:04:08
According to my colleagues in USA the biggest issue with these patients is the high requirement for PEEP at level of >16 what would you think this product would need to be capable of?
Henro Ritchie
01:05:45
As stated this system prefers non-electrical design. Is their an alternative work stream for pro-electrical design? I think their are a number of electrical/electronic teams who would like to help, but not with this work stream.
Regardt
01:06:06
@Elizabeth, this is SSA4003-0009-000 and SSA4003-0009-002, not SSA4003-0009-001.
Johan’s iPhone
01:06:21
If this (cpap) is the solution why hasnt Europe or USA not developed this idea instead of urgently looking for ventilators and ventilators are capable to give cpap (same as this system.
Japie Ludick
01:06:48
Johan, we welcome the offer to assist in this regard. There will be large amounts of CAD data being created and this needs centralised management. The main function is generating accurate data for manufacture (DFM) and to develop the BOM. Interface management will be key.
Eleanor
01:07:06
Why would the commercially available High Flow oxygen delivery devices not be of the same value
Johan’s iPhone
01:07:41
patients with covid oneumonia frequently needs peep values more than 10 cm of water pressure
Clifford
01:08:40
Is there any intention to, in parallel, expand the true (invasive) ventilator capability in South Africa? I.e. a separate endeavour to this?
Lance Michell
01:08:46
High flow nasal O2 is considered high risk for viral dispersion and not recomended
Eleanor
01:09:02
thanks Lance!
LJ
01:09:57
Might a commercial sleep apnea (fan-driven) CPAP product be good enough to act as pressure source?
Juan Strauss
01:10:31
how practical is the hoodie in field conditions to achieve positive seal?
Klaas Pouwels - Waco Africa
01:10:46
Can we consider a venturi to mix the air and oxygen without an electronic / mechanical oxygen blender ?
Trevor NCS
01:11:27
Will the process be open to all interested persons (as observers) irrespective of the success of the selected design in order to provide assistance/input for specific hurdles encountered as and when they arise up to full scale deployment?
Lance Michell
01:12:00
Yes the commercial turbo driven CPAP systems are useful in the UK experience
Chris de Villiers Eskom
01:12:16
Please define low cost? 5k 50k 500k?
Dennis Bouwers
01:12:19
Thank you for the presentation, very clear on what is requested.
Regardt
01:12:25
Can you inform us who forms part of the medical team that you have consulted?
nora
01:12:27
Hi Trevor. I hope so as all support should be desirable.
Rhys Couzyn
01:12:38
Could you please share the specs of the Wall O2 supply: Pressure, flow, bore (22mm?)?
Farid HAFEZ
01:13:57
Any plans to assist with the import of needed components, accelerating clearances and waving custom tariffs, etc?
Hanif Banderker
01:14:30
The Medtronic system is not open-source and has a sunset clause in the "permissive license".
Thamsanqa MAQUBELA
01:14:53
The time lines for RFP submissions is not realistic. we need an extension to April 8, 2020.
gavo
01:15:13
Repro Supplies is able to offer full conventional assembly, SMT population and a full tool shop (for injection moulding etc) shout if anyone needs assistance as we are willing to help in anyway - contact me at gavo@mweb.co.za
markbanfield
01:15:23
What SAHPRA regulatory requirements have to be kept in mind or complied with?
Japie Ludick
01:16:20
Faried HAFEZ asked " The mask has to be removed for the patient to eat and drink!" The anti-asphyxiation valve is integrated in a removable lid to the patient access port with diameter 130mm.
Dr Jean-Patrick Leger
01:16:31
Please do not exclude the possibility that ambubags can be manufactured in South Africa - it may be a challenge, but could be done
Dr Jean-Patrick Leger
01:16:46
There are already people working on this
Lance Michell
01:17:29
Im concerned about humidification. Agree it does not have do be 100% but the O2 will be very dry and make it intolerable to the patients. HME would require a common inspiratory - expiratory port on the helmet and HME's are probably have to be imported . Maybe allow for humidifier to be inserted into the inspiratory limb if available
phillipdevilliers
01:17:40
Has the Vortan “Go2Vent” been considered as a design to be used in a non medical setting, where all that can be provided is possibly a oxygen tank, this would be needed prominently in the informal settlements.
Neville Ephraim, iGas
01:17:44
iGas is not is a position to submit a proposal. However, we are interested in providing Funding. How do we do that? Or does that need to be an offline discussion?
Mike Jessop
01:18:53
Please consider earlier emailed questions in response
Clinton Bemont
01:19:00
Speaking of lack of availability of Ambubags and other medical devices, I can import complete ventilators, BiPAP, CPAP, Ambubags, pulsioxymeters, COVID test kits.
Clinton Bemont
01:19:32
But the ability to import drops eax
Drako and James
01:19:57
For how long is a person on this ventilator expected to be ventilated? What is the requirement for continuous operation between operating service cycles?
Drako and James
01:20:21
ie the expected maximum time that a patient can be continuously connected to the ventilator
Johan’s iPhone
01:20:32
high flow oxygen in WHO as well as SASA published guidlines as well as warnings about so called non invasive methods. Morel obligation then to make sure if this system is deployed that caregivers have access to suitable PPE
Michael Cousins
01:20:32
I have also heard of this need for an elevated PEEP (positive end-expiratory pressure). This may eliminate hood/mask options depending on the required sealing pressure. Any indication what this may be?
Harry Teifel
01:21:30
Will products be excluded from government purchasing, which did not go through the SKA process? Does this also apply to private and NGO purchases?
Julian Wills
01:21:33
Please forward details of suppliers of standard medical hoses, circuits, fittings, air filters, masks, so we can incorporate these into our ventilator designs. also circulate details of part supply proposals, so we can concentrate on our address of specialisation.
Rhys Couzyn
01:23:24
Regarding power, does wall O2 not require electricity in any case?
Regardt
01:23:53
Why is DTIC taking charge? Is the Department of Health providing input or involved at all?
Johan Pretorius
01:24:02
Can a tight fitting mask be used with a good (silicone and air) seal and valve, rather than a hood as such?
Renai Moothilal
01:24:15
given the various bits of clarity on process and tech specs that are coming out on this chat, there may be value in extending responses for call for proposals by 24hrs, to 23.30 tomorrow?
George Gericke
01:24:17
Is there an opportunity for collaboration within the group and how? We have working models but our biggest challenge has been getting parts for prototypes and the rapid fabrication, especially due to lockdown causing some parts set as non-essential
Deon
01:24:55
Proposal may be rather large.Can we send proposals via WeTransfer?
Dave Gouws
01:25:02
Can we still submit designs after closing date
Trevor NCS
01:25:25
I have created a Facebook page for informal discussion around "Ventilator Designs in an African context". The group is called Ventilate Africa. This can perhaps be a great offline discussion thread for everyone who wants to bounce ideas?!
Farid HAFEZ
01:26:11
Can you briefly clarify why your requirements call for a CPAP only system as opposed to a system that can be used for CPAP as well as active ventilation, which will be needed for large number of cases?
327031
01:27:12
on your document i see you ask fro cost/unit and total cost. at this stage can we submit the proposal. and the commercilas at a later stage once the designed has been considered,.
Johan Pretorius
01:27:29
MASK VS. HOOD: Can a tight fitting mask be used with a good (silicone and air) seal and valve, rather than a hood as such?
Harper Sports Cars
01:27:43
Willem, we are busy with a prototype that includes mechanical ventilation using the Ambubag and doesn't require any electrical power. Would this meet of exceed the minimum requirement spec?
bob.elshove
01:29:38
With clarifications now received in this session, can the submittal date be extended to Thursday 9th Apr 23h00?
Lance Michell
01:30:25
The hood/helmet has the benefit of less viral dispersion then the mask
Harper Sports Cars
01:30:28
A general statment: As this wave of Covid Infections passes through various countries, an internationl ventilator project might be useful to move ventilators around the globe as they become redundant.
Regardt
01:32:08
@Lance, until the patient needs to eat or drink
Drako and James
01:33:03
For how long is a person on this ventilator expected to be ventilated? What is the requirement for continuous operation between operating service cycles?
Drako and James
01:33:14
Can we get an indication of this: as above -
Lance Michell
01:33:49
We tube feed in ICU. A port in the helmet for feeding tube is an option
Simone Rudolph-Shortt
01:34:30
VERY good question re liability
Regardt
01:34:51
@Drako, according to spec, 14 days operation and turn around time of 1 hour.
Simone Rudolph-Shortt
01:35:24
If someone is in ICU then this is not related to this project as I understood this is for early treatment?
N.Human
01:35:55
Will special permits be issued to ensure unrestricted support of the activities to companies going through to next rounds and that can actually produce the required components/systems. Current travel restricted, even with essential service permits
Simone Rudolph-Shortt
01:35:58
Is there a list of components and parts
Clifford
01:35:59
What if oxygen supply fails? Assume anti-asphyxiation is good enough. Could this contaminate blender? Non-return value mentioned earlier might be a good idea.
Regardt
01:36:00
@Lance, if viral dispersion is important, should the feeding tube not form part of the spec then?
Sparrow
01:36:18
Where can we find the specs on the hospital gas line connectors and oxygen outlets? Can we submit a design assuming we can add this afterwards?
George Gericke
01:37:32
Is there a separate project for more advanced mechanical ventilation, ICU stage?
Graham Raynor
01:38:05
the gorilla in the room - what do you mean by low cost. It could be that our solution is out of your ball park and it would be nice to know before continuing with the RFP
Robert Mawbey
01:38:21
Are there any existing products (commercial or open-source) that the reference design is most similar to? i.e. something existing you are evaluating against?
Klaas Pouwels - Waco Africa
01:38:30
what is the official email address for the CFP submission ?
Pontsho Maruping
01:39:03
all submissions to be sent to nvp@ska.ac.za
Drako and James
01:39:07
the gorilla in the room - what do you mean by low cost. It could be that our solution is out of your ball park and it would be nice to know before continuing with the RFP - also want to know this pls
Drako and James
01:39:15
what is the range?
dr Sam Phalafala
01:39:37
Are the components available locally? if not acquiring them of sure will delay production as per requirement.
Sparrow
01:41:41
If we need to build a prototype during lockdown, how do we get suppliers permission to open shop?
Johan’s iPhone
01:41:54
Is there a separate project for more advanced mechanical ventilation, ICU stage?
Terry Wickham
01:41:58
Would a unit that is more than 80% locally sourced and manufactured, but under an exclusive manufacturing license from offshore be considered?
Pontsho Maruping
01:42:18
https://www.sarao.ac.za/media-releases/sarao-mandated-to-manage-the-production-of-respiratory-ventilators/
Hendri

Have you looked at the N200 Penlon Ventalator
N.Human
01:43:04
Willem and team, great work. You have a Mammoth task and we all hope you succeed in saving lives, if even 1 of us. All the best
Murray Bredin, Shock Wave Engineering
01:43:41
How does the expected oxygen use compare to supply of medical oxygen? If the control / operation is not accurate and the systems use more oxygen then do we risk overwhelming the supply?
RJulies
01:43:45
Thank you for great work. together we stand to make this a success, Dahlhausen Pty Ltd Germany
