Chapter II. Product Description

1. Product Description
EPIA is a handheld device using internal power, which can hold a 5 mL syringe and an epidural needle. EPIA assists the epidural needle to be inserted and approach the epidural space. An operator can control the movement of the syringe and the insertion of the epidural needle. While the epidural needle is being inserted, a pressure sensor located in EPIA detects the change of pressure (Reaction Force) applied to the tip of the needle, converts the pressure data of each tissue to digital data and indicates them as a graph on a display device. The operator can determine the target injection site by monitoring the pressure change in the graph and can control or stop the movement of the epidural needle at the target site, which is the epidural space. When needed, the device can be detached from the syringe, and the operator can inject an anesthetic directly or can insert an epidural catheter.

2. Features
 Data transmitting via Bluetooth communication or USB data cable  Real-time graph shown by display device  Visualization of pressure and needle insertion length  Internally powered  5 mL syringe compatible  Steady and stable needle insertion  Fine control of needle movement ­ Safety control button (0.2mm fine advance, stop, backward)  Safety function ­ Automatic stop when the pressure detected is 50 gf lower than the maximal pressure
detected.  Applicable for various treatments accompanying epidural anesthesia and pain control

3. Intended Use
EPIA is an epidural instrument intended for use with an epidural needle for the real-time confirmation of the needle tip placement into the epidural space. The device assists in the insertion of the needle into the epidural space by showing the needle insertion progress and the pressure data of each tissue as a graph of reaction force on a display device.

3.2. Age
18 years of age and older
3.3. Application Part

3.4. Intended Medical Indication
- Epidural anesthesia - Pain control (labor analgesia)
3.5. Patient Contacting Part
None
3.6. Potential/Possible Adverse Reaction
- Cerebrospinal fluid leakage due to dural puncture - Spinal nerve damage - Pain in the treatment area
3.7. 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.

4. 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. EPIA also makes use of this phenomenon and detects reaction force, which is made against the force that the needle penetrates the tissue. While the tip of needle inserts through the subcutaneous and ligament tissue, the reaction force as well as pressure at the tip of the needle increases ( and  in the graph below). When the tip of needle reaches the epidural space, the pressure and the reaction force rapidly decrease (). The pressure sensor of EPIA detects this change in reaction force and convert it as visual data.

3. Instruction to Use

 Prepare the sterilized EPIA device, an epidural needle, and a 5 ml syringe. If needed, fill the syringe with saline or an anesthetic to be injected into the epidural space.
 Remove a stylet from the epidural needle.
 Combine the syringe and the epidural needle.

 Open the syringe cover of EPIA by pressing the OPEN

button.

 Insert the flange of the syringe barrel into the syringe holder of EPIA and place the needle in the groove in the front of the device.

When using a Tuohy type needle, insert the needle and syringe in the correct direction considering the bevel (slope) of the needle tip and the curved direction. Typically, the bevel faces to anterior (cranial, toward head) so that the injected anesthetic can easily spread into anterior epidural space.







 Close the EPIA cover until it clicks and secure the syringe to avoid shaking.
 After connecting EPIA to a display device (Please refer to "section 2. Device Connection of Chapter III"), run the program on the display device.
 Before the start, check that the graph is located at the start (setting) position. (The X and Y axes of the graph in the program should be located at 0.) Also check that the syringe holder of EPIA is located at the start (setting) position.
For the proper insertion, it is recommended to protrude a part of needle (about 20 mm) by pressing the Forward button and then Stop button. Use the protruding part of the needle, to insert it into the injection site in advance.

RIMS-IFU-001 / Rev. 1

Page 29 / 43

 Insert the protruding part of the needle into the patient's injection site, and hold the EPIA firmly against the operation site.
Hold the EPIA firmly and fix it onto the patient's injection area with one hand (left hand recommended). Operate the buttons of EPIA with the other hand (right hand recommended).

 By pressing the Forward button,

the syringe and the needle will automatically advance, and

the needle will be inserted into the patient's body.

During the operation, make sure that the device is pressed firmly against the injection area to avoid being pushed back.
During the operation, the plunger is not affected, thereby the anesthetic is not injected while the needle is being inserted.

 The pressure data are transmitted in real-time to the display device. Through the pressure graph, the operator can monitor the intra-insertion movement of the needle, needle insertion length, and the pressure change applied to the needle.

 When the tip of the needle enters the epidural space, the pressure decreases rapidly. While monitoring the changes in the pressure graph, the operator can stop the progress of the needle
by pressing the STOP button .

By detecting a rapid drop in pressure, the device will automatically stop at the epidural space. The operator can confirm that the pressure is constantly kept low by pressing the 0.2 mm button, thereby confirming that the automatic stop point coincides with the epidural space.

 After the stop, if additional progress is required, press the 0.2mm button needle finely.

to advance the

If a withdrawal is required, press the Back button

to move the needle backward.

RIMS-IFU-001 / Rev. 1

Page 30 / 43

 When the needle is located at the epidural space, open the syringe cover, and remove the EPIA device from the syringe.
Remove the EPIA carefully so that the tip of the needle located in the epidural space does not deviate from its proper position.
The operator can confirm whether the needle has reached the epidural space successfully by using the Loss of Resistance (LOR) Method, manually pressing the plunger to check the pressure within the syringe.
 LOR (Loss of Resistance) method: The method to check the pressure within the syringe by manually pressing the plunger of the syringe. At the epidural space, where the relative pressure is lower, the pressure within the syringe decreases thereby the plunger goes into the syringe.
 Push the plunger of the syringe to inject the required amount of anesthetic. Alternatively, after removing the syringe from the needle, an epidural catheter can be inserted into the epidural space through the epidural needle that is inserted into the treatment area, then subsequent procedures can be taken.
