At 2020 COVID-19, Personal Protective Equipment (PPE) has run out.
We found that stationery was often used to make up for the shortage.
We focused on the face shield, which is one of the protective equipment.
Plastic clear document holders are unstable, so we developed a universal frame.
This universal frame is for holding the film.
The mounting position is on the head.
Prepare a universal frame manufactured by a 3D printer.
Prepare an arbitrary film such as a plastic clear document holder.
Insert the sheet into the half-moon shaped slit in the frame.
Use a stapler to prevent the film from falling out of the slit.
Thread rubber bands through the left and right holes.
This is a case where the ring is enlarged using a double ring and fixed with a stapler through a 25 mm rubber.
The thicker the rubber is, the more stable it will be, so if you pass rubber of about 25 to 30 mm, it will be more reliable.
It is designed to have a width and thickness that can be applied to stationery.
Medical sheets can also be used.
There is a danger that it will fall off if it is supported by several holes.
The universal frame holds a wide range of surfaces.
It is important not to fall during the procedure.
We have a lineup of standard type and small face type.
The height is sufficiently higher than the height of the glasses and nose.
Use a rubber band to go around your head.
The frame makes it difficult to drop once it goes around.
Designed to keep users safe as a top priority.
We adjusted the size to reduce the manufacturing time.
In addition to our universal frame, many frames are open to the public.
Please choose the one that suits your purpose.
We requested more than 10 medical institutions to evaluate Universal Frame.
The evaluator was mailed a prototype manufactured with a 3D printer.
We have made some corrections based on the reviews we have gathered.
After correction, it was prototyped and evaluated again.
We will continue to listen to the opinions of healthcare professionals.
The photo shows the manufacturing progress on April 25, 2020.
On April 30, we donated these frames to the Osaka Women's and Children's Hospital (Osaka Prefectural Hospital Organization, Japan).
Donated to Bell Piano Hospital.
This hospital is a private hospital in Sakai City, Osaka Prefecture.
We aim to make donations for all nurses.
We publish design data. This data is provided free of charge.
It takes a lot of time for us to manufacture a universal frame.
We cannot make it in time.
I would like to ask everyone who has a 3D printer.
Please manufacture a universal frame and donate it to the hospital.
I'm running out of face shields in a small hospital.
Visiting nurses also lack face shields.
The face shield of the assistant staff is also lacking.
Type-D is the same size.
This type can bind a film with a maximum width of 300 mm.
Type-D is recommended for 3D printers for home use. Type-C is fine for high-performance printers.
We use a 3D printer (Fused Deposition Modeling) for home use, so we manufacture and donate with Type-D.
An auxiliary floor has been added to prevent the walls from collapsing during manufacturing.
Other than that, it is the same as Type-C.
The STL data that is the basis for manufacturing with a 3D printer is released.
Anyone can download it right now.
No registration is required.
The molding plate size is designed to fit within 20 cm x 15 cm.
The design data does not include a unique symbol such as a logo mark.
Please manufacture with STL data.
Please contact the respective manufacturers for information on how to use the 3D printer.
Recipe for Creator Pro (FlashForge)
We use a model called Creator Pro of FlashForge.
Printer: Creator Pro (FlashForge)
Conversion software: FlashPrint (FlashForge)
In Type-D, it is necessary to cut out the auxiliary floor.
You can easily cut it with a cutter knife.
Press the cutter knife along the half-moon shaped frame.
Instead of cutting off strongly, it is gently scratched.

Stationery has problems with distortion and transparency.
However, since it is out of stock, I use it without help.
I will introduce an example that was slightly processed to improve the wearing feeling.
Invented by the ground staff of a Japanese airline (ANA).
I am diverting the card case for office supplies.
It is a design drawing of Mr. Yoshioka who designed the torch for the Tokyo Olympics.

Our products are also listed.
I belong to a Japanese company or organization.
I have a Japanese license "Clinical engineer" and "Electrician".
I am a healthcare professional and a consultant.
As a person with clinical experience, I support the commercialization of research and development related to medical care and healthcare.
I use 3D printers for prototyping for commercialization.
We use 3D printers to solve the problems that healthcare professionals face.
