CAI
Cortical Activity Index

Depth of Anesthesia Monitoring System

CAI is a brain monitoring system that links patient-specific EEG information to an individual’s level of consciousness collecting the raw EEG data that indicates the patient's response to anesthetic agents in real time and displaying it as the CAI index value (a number between 0 and 100) . This information helps clinicians optimize drug administration for each individual patient, leading to increased patient safety, comfort, and satisfaction during surgery and preventing potential medical accidents such as intraoperative awareness.

Background

Intraoperative Awareness?

An estimated 20,000 to 40,000 patients experience awareness out of the 20 million surgeries performed yearly in the United States alone.


Anesthesia awareness (waking up) during surgery, means the patient can recall their surroundings, or an event related to the surgery, hear noises or even feel the pain whilst undergoing surgery. Long-term effects include anxiety, sleep disturbances, flashbacks, nightmares, PTSD. Some cases of awareness might occur as a result of inadequate anesthetic dosing and therefore constitute potentially preventable medical errors.


CAI is a device helps address each patient's unique anesthetic requirements preventing the risk of awakening during anesthesia and helping to ensure a safe surgical experience.

VET CAI

Depth of Anesthesia Monitoring System For Pet


VET CAI is the world's first medical device that monitors animal's level of consiousness during surgery by analyzing their brainwaves and measuring the depth of anesthesia by indexing it. This prevents surgical accidents, such as anesthesia deaths due to overanesthesia and trauma due to awakening during anesthesia. VET CAI brain monitoring system helps veterinarians determine and administer the precise amount of drug to meet the needs of each individual pet. It is a medical device that monitors the level of consciousness of animals during surgery by analyzing their brainwaves and measuring the depth of anesthesia by indexing it.

The world's first Depth of Anesthesia Monitoring System for Animals

 

The world's first medical device that monitors animal's level of consiousness during surgery by analyzing their brainwaves and measuring the depth of anesthesia by indexing it. VET CAI helps assess brainwaves to help doctors accurately gauge unconsciousness and adjust anesthesia. 

Considering Ethics and Aesthetics with Non-invasive EEG measurement 


Like any pet owner, our greatest concern is the health of your pet. We can safely monitor your pet's status during surgery without having to shave the fur unlike within conventional invasive methods that may cause infection or side effects on top of that .

Electrode Design 

for Different Applications 

and Brain Structures  

 

We are currently developing a variety of electrode array designs for different applications and brain structures that can be adjusted in size and used with thick and dense haired animals

ST1
(coming in 2025)

Electric/Thermal Stimulator for Better Sleep
A healthcare wearable that helps improve sleep and combat stress with the use of PNS


ST1 is an extremely delicate and non-invasive alternative treatment that helps improve sleep quality by delivering effective nerve stimulation through PNS*.  When you attach it to sleep-related nerve points based on oriental medicine the device induces sleep by stimulating microcurrents. ST1 uses low levels of electrical stimulation to activate nerve pathways in the body. These pathways communicate with areas of the brain to help control stress levels and sleep quality. The product is targeted towards consumers who frequently suffer from stress and consequently struggle to sleep.


Precise stimulation of nerve points


A small wearable aimed to alter the flow of Qi in the body to rebalance the body's flow and restore physiological functioning, 

enhancing blood flow to certain sleep-inducing regions of the brain.

Safe sleep disorder solution

without side effects


We help you safely induce sleep and improve sleep disorders

without worrying about the side effects of taking medicines such as sleeping pills. 


Patent application: Transcutaneous electrical stimulation device with added heating function

(10-2023-00001722)


Easily adjustable stimulation intensity via APP


ST1 application allows you to view and adjust the intensity of the stimulation in real time.
