DMF Lab Experience

Our skills like in rapid manufacture and effective/efficient low-end production using rapid manufacture systems. We do not have manufacturing capability to substantially support production efforts of any device, experience of design of medical devices or clinical knowledge, or testing facilities to confirm our designs functionality.

The DMF group is therefore concentrating on:

  • Refinement of existing designs for rapid manufacture, etc.
  • Acting as a conduit between projects and companies to increase opportunity for production at industry scale.
  • Offering our skills on a request basis

We see our primary design-based value resting in refinement of existing designs for manufacture and assembly efficiency, maximisation of standard parts, part count reduction, flat-packing and distribution etc.

Many designs, particularly open-source and low-end, make heavy use of 3D printing technologies, which are slow, inaccurate, and produce bulky parts. We have spent time demonstrating refinement of existing open-source designs to reduce manufacture time and simplify.

If you feel your project could benefit from our help, please contact us using our individual email addresses (on our people pages) or harry.felton@bristol.ac.uk.

Other COVID19 Projects and Information

Please see the list below for projects you and your company may be able to help with. We will endeavour to keep this list as up to date as possible over the coming weeks and months.

1.    MHRA Spec

The Medicines and Healthcare products Regulatory Agency, a subsidiary of the UK government, has produced a document detailing the minimum requirements of a ventilator to be used in NHS hospitals during the current pandemic. This document can be found through the link below and via the blog post here. We have also distilled this document into a PDS style requirements document. This should be considered a live document and will be updated regularly.

https://www.gov.uk/government/publications/specification-for-ventilators-to-be-used-in-uk-hospitals-during-the-coronavirus-covid-19-outbreak

The most difficult part of the specification for us are the levels of control and sensing required. These elements would require hardware testing and refinement that are not currently possible given our working arrangements. These elements would require input from electronic engineers and specialists with experience in medical devices.

2.    Royal Society Rapid Review

This is an effort being led by the Royal Society to have a rapid review schedule for papers submitted on work around COVID-19 where work will be reviewed within 24-48 hours post-submission. More information for reviews and authors can be found through the link.

3.    Oxvent

This is a project being run between the University of Oxford and King’s College London. It is a multidisciplinary team of medics and engineers aiming to produce a ventilator to fill the shortfall health care systems across the world are anticipating and experiencing.

4.    Prusa Medical Shields

The open-source 3D printing company, Prusa, has started to use its 3D printer farm to print open source components for face shields. It is currently producing 800/day using 1/5th of its printing capability. The safety of the mask is currently being verified. Several suggestions are provided on Prusa’s website on how to print the parts along with handling.

These groups cover design, manufacture, testing and research review.

8.    Welsh Rapid Ventilator

The Welsh government has given the green light, and successfully tested, a new, rapidly designed ventilator. Although this does not meet the specification required for use in ICU wards it is considered an important contribution to reduce the demand on ICU beds. More information on this can be seen here.

9.    UK Companies

Several large UK engineering organisations are also developing designs. Two of the most advanced are G-Tech, who are nearing production ready and have been asked to manufacture 30,000, and Dyson who have had an order of 10,000 placed by the UK government.
