- | ====== REESpirator2020-Bricolabs prototype ====== | ||
- | |||
- | **Reespirator** aims to contribute to solving the lack of mechanical | ||
- | ventilation devices in emergency situations. In recent days, many | ||
- | countries in Europe were faced with a difficult health situation due | ||
- | to the high and timely demand for technical resources caused by the | ||
- | CoVid-19 pandemic. The situation is gradually returning to normal, but | ||
- | at present it is uncertain how long and how many waves this virus will | ||
- | eventually produce, and whether emergency devices such as the | ||
- | REESPIRATOR2020 ventilator will ever be needed. | ||
- | |||
- | The pandemic has become a global problem, with great uncertainty about | ||
- | the current and future impact on different countries depending on | ||
- | their climate, living habits, health resources, economic | ||
- | situation, | ||
- | they are not certified medical equipment, can help to lessen the | ||
- | effects of this disease, as support or main ventilation devices. | ||
- | |||
- | On the other hand, many countries and communities have a structural | ||
- | lack of technical health resources that makes it difficult or | ||
- | impossible to treat adequately diseases that would be much more | ||
- | advantageously treated in Europe. This situation predates CoVid-19 and | ||
- | is likely to continue after the pandemic is brought under control. | ||
- | Although emergency teams may not be needed in Europe, they can always | ||
- | be useful in countries and communities with weak health systems. | ||
- | |||
- | Reespirator is an Open Source emergency ventilator. The aim of the project is | ||
- | to collect and publish all the necessary information so that a device | ||
- | to help in specific or permanent emergency situations can be built | ||
- | with few resources. The documentation will be released under a | ||
- | creative commons license in order to make its access as free as | ||
- | possible, and at the same time allowing that the improvements or | ||
- | adaptations made will result in better information for those who are | ||
- | encouraged to build one of these devices. | ||
- | |||
- | <note warning> | ||
- | not medically certified and is not expected to become so. The | ||
- | responsibility for the use of the device must be assumed by whoever | ||
- | decides to build and use it.</ | ||
- | |||
- | ==== Technical Characteristics ==== | ||
- | |||
- | At [[https:// | ||
- | document]] there is a basic introduction to the main functions of | ||
- | today' | ||
- | the Reespirator2020 to have. Initially we are implementing the | ||
- | **pressure control** mode completely and safely, both in the Arduino | ||
- | based version and the PLC based version. We are working on the | ||
- | electronics, | ||
- | simultaneously. This stage is what we call //Release 1//. | ||
- | |||
- | ==== Information published ==== | ||
- | |||
- | **Repository of the original project | ||
- | [[https:// | ||
- | description of the hardware and equipment needed to buildt the | ||
- | respirator. It includes a software to work with arduino and an | ||
- | advanced display around a Beagle Bone. | ||
- | |||
- | This model has been validated with artificial lung and animal model. | ||
- | However, it is possible that any change in the configuration or the | ||
- | control system will require a new validation process. | ||
- | |||
- | **Repository of the | ||
- | [[https:// | ||
- | the original project. In the folder Respirator2020 there is a complete | ||
- | description of the current state of the project, with building | ||
- | plans for laser/CNC cutting, principle diagrams, electrical and | ||
- | pneumatic diagrams, software and list of materials. | ||
- | |||
- | There are two major implementations, | ||
- | study. One is based on an industrial PLC from SIEMENS, which is a | ||
- | little more advanced, and the other one is based on arduino MEGA or a | ||
- | similar architecture. The first one uses a proprietary touch screen, | ||
- | while for the second one a communication protocol and a control | ||
- | program in LINUX has been developed. This programa can be executed in a Beagle | ||
- | Bone, Raspberry or any laptop with Linux. The functions of the touch | ||
- | screen are the same in any case, and include control menus, parameter | ||
- | setting and operating modes, graphics, alarm management, etc.. The | ||
- | version with arduino also includes a basic low cost control around a | ||
- | 4x20 character LCD display that allows to manage all the functions of | ||
- | the equipment, but not to see graphics. | ||
- | |||
- | There is still a lack of information in the communications sections, | ||
- | electronic board, diagram, and others that are being developed. Also | ||
- | missing is a complete list of materials needed to build the | ||
- | Respirator2020, | ||
- | development phase. | ||
- | |||
- | ==== Work in progress ==== | ||
- | |||
- | There are several working groups that are coordinated through telegram lists: | ||
- | |||
- | * **ARDUINO: | ||
- | |||
- | * **ELECTRONICS: | ||
- | |||
- | * **SENSORS: | ||
- | |||
- | * **PROTOTYPES: | ||
- | elements. They will also serve to initiate the tests that can be made depending on the resources available at each location. | ||
- | |||
- | ==== EUvsVirus ==== | ||
- | |||
- | During the weekend of April 24-26, 2020, the prototype | ||
- | **bricolabs-rees-2020** will participate in the European-wide hackaton | ||
- | [[https:// | ||
- | |||
- | These days we were updating the documentation of the equipment, | ||
- | looking for materials to complete it and advancing in the programming | ||
- | of the control loops with the intention of having a functional | ||
- | equipment in a term inferiors to one week. Specifically: | ||
- | |||
- | * Mechanical adjustments to the prototype | ||
- | |||
- | * Connector design for patient side tubing | ||
- | |||
- | * Selection of the expiration zone solenoid valve and Jackson Rees | ||
- | device elements | ||
- | |||
- | * Advances on the LCD-based low cost control panel | ||
- | |||
- | * Discussion of the implementation of control loops. | ||
- | |||
- | * Exchange of ideas and proposals with other teams that are | ||
- | developing their own mechanical fans | ||
- | |||
- | ==== How to participate ==== | ||
- | |||
- | One option is to review the information and think about what you can | ||
- | or want to join. Telegram groups are quite mobile, but allow everyone | ||
- | to join in according to their time and desire to get involved. | ||
- | |||
- | In Bricolabs we are building a prototype. Despite the confinement | ||
- | there are tasks that can be done, such as designing and printing | ||
- | parts, testing sensors, managing purchases, | ||
- | many others. | ||
