YEZAK
Ensuring patient safety through every step.

Prioriizing SAFETY
Contagion Control Methods
Yezak ensures even safer infection control with the latest sterilization robots. With 99.99% virus blocking, we carry out infection prevention measures and regular hospital sterilization.

99.99%
Virus Sterilization
For safety, we carry out thorough disinfection using sterilization robots. Yezak has introduced a sterilization robot that completed a ‘99.99% coronavirus sterilization clinical trial’. The robot safely disinfects all surfaces and the air throughout the hospital, and because it performs 3D sterilization of the entire space, it makes the environment much safer than before.

Sterilization Robot Certificate of Disinfection Certification
It has been certified as a superior product by having its sterilizing power directly certified by nationally recognized institutions and university research teams.

LABEL SYSTEM
Tracking Management Label System
This system is primarily used in university hospitals, where patient volumes are difficult to manage. It is issued to all surgical patients and is tracked throughout their stay, reducing the likelihood of changes in doctors, procedures, and medications.

Triple check
Coordinator, Assistant, Doctor
Recently, the media has reported increasing cases of “ghost doctors” and accidents caused by medication errors. However, at Yezak, instead of relying on an unstructured system, we apply a university hospital-style tracking system. Through a triple-check process involving coordinators, assistants, and doctors, we ensure a much safer medical service.
Trace & Management Label System Process

01
Registration & Consultation
Through registration and consultation, personal information is recorded and the surgery plan is determined.

02
Wristband Label Issuance
At every stage—from the information desk to the consultation room and operating room—verification is carried out to ensure full traceability and management.

03
End-to-End Precision Care
After surgery and before discharge, personalized precautions and prescriptions are provided with no risk of changes or errors.
