2.7. Contraindications
- Do not use on a patient with sepsis, bacteremia, injection site infection, severe hypovolemia, severe
coagulation abnormalities, therapeutic anticoagulant therapy, increased intracranial pressure, and patient
refusal.
- Do not use on a patient with neurological disorders, mental illness or dementia, aortic stenosis, left
ventricular outflow tract obstruction (LVOTO), and congenital heart disease.
3. Principle of Operation
The product is used to assist with an epidural procedure that detects the epidural space by automatically
pushing the syringe barrel to insert the epidural needle into the epidural space.
The motor rotates by using the electric power of a 3V battery, and the rotational motion is converted to a
linear motion of the syringe barrel and the needle fixed to the syringe holder.
While the epidural needle is being inserted into the body, the pressure sensor in the syringe holder detects
the pressure change between each tissue. The detected pressure change is converted and stored as digital
data and displayed as a graph on the display device.
When the epidural needle is inserted into the body, the pressure will gradually increase in the
subcutaneous and ligament tissue, and the pressure will rapidly drop when it reaches the epidural space. In
this way, the operators can verify whether the needle tip has successfully entered into the epidural space.
