An improvised protective device for use when intubating patients designed by Taiwanese doctor Lai Hsien-yung (賴賢勇) is being adopted in the Philippines to help doctors there stay safe amid the worsening COVID-19 pandemic.
“We made this acrylic aerosol box for my sister Dra. Frances Legaspi for Antipolo Doctors Hospital. Credits to Dr Lai Hsien-yung for the concept and design,” Anton Legaspi, whose family owns a business that makes customized designs, said on Facebook on Monday.
The hospital is in Antipolo, about 25km east of Manila.

Legaspi’s post was accompanied by several photographs of the box and a short demonstration video that was shot in the hospital. As of yesterday morning, his post was shared more than 60 times.
The “aerosol box” designed by Lai, an anesthesiologist at Mennonite Christian Hospital in Hualien, is a transparent cube made of acrylic that covers a patient’s head during endotracheal intubation, a necessary procedure for patients with the coronavirus who experience respiratory failure.
It has two holes on one side through which physicians can insert their hands to perform the procedure while shielded from the patient’s respiratory droplets.
Lai on Saturday shared his design on Facebook and gave permission for its noncommercial use. His invention was reported by the Central News Agency (CNA) and several other local media outlets.
Legaspi yesterday told CNA in an interview that he and his sister, an emergency room doctor, learned of the device on Sunday night through posts shared on social media and created the prototype the next morning, overcoming challenges caused by a lockdown of Metro Manila.
“We were lucky enough to get a supplier who had available stocks of raw materials. The workers at the shop live at the factory, so we were able to make it,” Legaspi said.
He said that his sister asked him if he could make such a box, because it was needed at the hospital as supplies of personal protective equipment in the Philippines are running low.
As of Monday afternoon, there were 462 confirmed COVID-19 cases in the Philippines, with 33 deaths and 18 patients who have recovered.
Legaspi’s version features larger holes to accommodate bigger arms.
Other suggestions he received from people in the medical field include making a small flap on the open side for additional maneuverability and protection, Legaspi said.
Donors and acrylic suppliers have pledged support for the production of the device, which would be donated to public and private hospitals nationwide, he said.
He estimated the cost of each aerosol box at 1,500 pesos (US$29.40), less than Lai’s estimate of about NT$2,000.
“It would be nice to have it mass-produced to cater to many more patients. It may still be used even after the COVID-19 pandemic,” Legaspi said.
The Coast Guard Administration (CGA) yesterday said it had deployed patrol vessels to expel a China Coast Guard ship and a Chinese fishing boat near Pratas Island (Dongsha Island, 東沙群島) in the South China Sea. The China Coast Guard vessel was 28 nautical miles (52km) northeast of Pratas at 6:15am on Thursday, approaching the island’s restricted waters, which extend 24 nautical miles from its shoreline, the CGA’s Dongsha-Nansha Branch said in a statement. The Tainan, a 2,000-tonne cutter, was deployed by the CGA to shadow the Chinese ship, which left the area at 2:39pm on Friday, the statement said. At 6:31pm on Friday,
The Chinese People’s Liberation Army Navy’s (PLAN) third aircraft carrier, the Fujian, would pose a steep challenge to Taiwan’s ability to defend itself against a full-scale invasion, a defense expert said yesterday. Institute of National Defense and Security Research analyst Chieh Chung (揭仲) made the comment hours after the PLAN confirmed the carrier recently passed through the Taiwan Strait to conduct “scientific research tests and training missions” in the South China Sea. China has two carriers in operation — the Liaoning and the Shandong — with the Fujian undergoing sea trials. Although the PLAN needs time to train the Fujian’s air wing and
STRIKE: Some travel agencies in Taiwan said that they were aware of the situation in South Korea, and that group tours to the country were proceeding as planned A planned strike by airport personnel in South Korea has not affected group tours to the country from Taiwan, travel agencies said yesterday.

Taiwanese celebrities Hank Chen (陳漢典) and Lulu Huang (黃路梓茵) announced yesterday that they are planning to marry. Huang announced and posted photos of their engagement to her social media pages yesterday morning, joking that the pair were not just doing marketing for a new show, but “really getting married.” “We’ve decided to spend all of our future happy and hilarious moments together,” she wrote. The announcement, which was later confirmed by the talent agency they share, appeared to come as a surprise even to those around them, with veteran TV host Jacky Wu (吳宗憲) saying he was “totally taken aback” by the news.
