Chulalongkorn University engineer develops hybrid wheelchair, wearable robot

A wheelchair that also serves as a wearable exoskeleton for people with mobility issues has been developed in Thailand.

The hybrid robot prototype allows its user to leave the wheelchair to stand and walk using an exoskeleton. 

"The lower leg can change mode between sitting and walking using a motor to help with the movement of the hip and knee joints. The ankle joint is a free joint with no drive. The left and right wheels can be retracted to the lower leg area to transform into a walking posture or get over obstacles," explained Dr Ronnapee Chaichawarat, an associate professor of the International School of Engineering at Chulalongkorn University. 

Dr Chaichawarat, who developed the hybrid robot with funding from the National Research Council of Thailand, is now building a second prototype with improved stability in sitting, standing, and walking. He is also preparing for its clinical trial.

Heuron expands to Japan

Heuron from South Korea has started supplying its medical imaging AI to Japan.

The company recently signed an exclusive deal with remote diagnostic imaging provider, Doctor Net, to distribute and sell its non-contrast CT-based acute stroke triage AI software across healthcare settings in Japan. 

They will also collaborate to obtain local regulatory approval for the AI solution, which they target by yearend. 

Respiree receives expanded HSA clearance

Singaporean startup Respiree has obtained clearance from Singapore's Health Sciences Authority for the expanded use of its wearable device to children.

Its device measures the respiration of patients with cardio-pulmonary diseases such as COPD and congestive heart failure. 

The clearance is also for the extension of its software, which now features automated alerts and symptom questionnaire generation and integrates with EMR systems. It also has API plugins that enable EMR interoperability.  

Respiree, which has been approved in Australia, Europe, and the United States, is looking to secure more regulatory clearances for its wearable device and AI-powered software-as-a-medical-device across Asia-Pacific. 

JLK secures more FDA approvals

Korean medical imaging AI company JLK has received its sixth and seventh United States Food and Drug Administration approvals.

It obtained 510(k) clearances for its integrated medical image management and analysis platform and AI software for detecting subdural haemorrhage in CT scans.

Most recently in January, JLK secured the US FDA's nod for its AI software supporting intracerebral hemorrhage diagnosis.
