The MolecuLight DarkDrape complies with ISO 10993-1:2009 / EN ISO 10993-1:2009: Biological evaluation of medical
devices.
2.3.1 Classifications
MolecuLight i:Xhas an operational duty cycle of 15 minutes on, 5 minutes off. The implication for this duty cycle is that if
the MolecuLight i:Xis continuously used in Fluorescence Imaging Mode for 15 minutes, the device will need to be switched
to Standard Imaging Mode for 5 minutes before selecting Fluorescence Imaging Mode again to allow for optimal
performance of the Violet Wavelength LEDs.
The medical device classification of the MolecuLight i:Xin Canada is Class II medical device and a Class IIa medical device in
Europe. Alone, the MolecuLight i:Xdoes not require patient contact for use. The MolecuLight DarkDrape (used in
combination with the MolecuLight Adapter and MolecuLight i:Xto achieve an optimal lighting environment for imaging
wounds) is a Type B patient applied part which complies with medical device biocompatibility requirements.
The MolecuLight i:Xis classified as “IPX0” for fluid ingress, therefore it has no inherent protection against damage from
exposure to liquids.
2.4 Electromagnetic Compatibility
The MolecuLight i:XImaging Device meets the requirements of Safety EMC Testing per IEC 60601-1-2:2014 4th Edition / EN
60601-1-2:2015. Medical electrical equipment requires special precautions regarding electromagnetic compatibility (EMC)
and must be used according to the instructions in this User Manual.
While unlikely, it is possible that high levels of emitted radio-frequency (RF) electromagnetic interference (EMI) from other
portable and mobile RF communications equipment or nearby radio-frequency sources could result in performance
disruption of the MolecuLight i:XImaging Device.
To avoid the risk of increased electromagnetic emissions or decreased immunity from such emissions, use only accessories
recommended by MolecuLight (i.e. MolecuLight Power Cable, see Section 3.1). Connection of accessories not recommended
by MolecuLight will void product warranty and could result in malfunctioning of the MolecuLight i:XImaging Device or other
devices located in the area.
This device complies with Part 15 of the US FCC Rules. This device complies with Canadian ICES-003 (B).
Note
The emissions characteristics of the MolecuLight i:Xmake it suitable for use in industrial areas and
hospitals (CISPR 11 class A).
MolecuLight i:Xis not intended for use in a residential environment
and does
not comply with
IEC 60601-1-11:2015 General requirements for basic safety and essential performance --
Collateral standard: Requirements for medical electrical equipment and medical electrical systems used in
the home healthcare environment.
2.5 Information on Laser Radiation Output
The MolecuLight i:XImaging Device uses a miniature pulsed laser-based range finder to determine the optimal distance
between the device and the wound for superior image quality. The laser module in the range finder emits light at 850 nm
which is invisible to the human eye. The laser’s individual pulse duration is 3.33 ns and the pulse train is 52.3 ms at a 200 ms
repetition rate. The laser complies with 21 CFR 1040.10 and 1040.11 except for deviations pursuant to Laser Notice No.50.
The laser is a Class 1 certified laser
Caution
Do not point the laser (from the
Range Finder sensor) into eyes (Figure 2, item 14).

i
:X Imaging Device Description and Use
The MolecuLight i:XImaging Device allows clinicians to quickly, safely and easily visualize potentially harmful bacterial
presence and distribution on skin and in wounds, in real-time at the point-of-care. The device is non-contact and no imaging
contrast agents are required for fluorescence imaging.
The MolecuLight i:XImaging Device is a handheld medical device comprised of a high-resolution color LCD display and
touch-sensitive screen with integrated optical and microelectronic components. MolecuLight i:Xuses its patented
technology to enable real-time standard light and fluorescence imaging of bacteria and tissue components in wounds and
surrounding healthy skin of patients.
The MolecuLight i:XImaging Device captures real-time images (JPEG format) and videos (MOV format) in Standard Imaging
ModeTM and Fluorescence Imaging ModeTM. These modes are identified as follows:

MolecuLight i:XTM User Manual Revision 1.1 Page 13 of 43
1. Standard Imaging ModeTM (or ST-Mode): Real-time imaging as per standard photography.
In Standard Imaging Mode, MolecuLight i:Xis able to capture the following images:
a. ST-imageTM: An image captured in Standard Imaging Mode
b. ST-videoTM: A video captured in Standard Imaging Mode
Note
Wound measurement is
only possible on an ST-Image (see Section 10).
2. Fluorescence Imaging ModeTM (or FL-Mode): Real-time imaging in Fluorescence Imaging Mode as a result of violet light
illumination. In Fluorescence Imaging Mode, MolecuLight i:Xis able to capture the following images:
a. FL-imageTM: An image captured in Fluorescence Imaging Mode
b. FL-videoTM: A video captured in Fluorescence Imaging Mode
The device provides image-guidance during visual assessment of wounds.
The device can capture an ST-imageTM, ST-videoTM, FL-imageTM, and FL-videoTM of wounds to quickly identify the presence
and extent of harmful bacteria. This helps to guide the clinical team towards a more comprehensive wound examination
through guided or ‘targeted’ debridement and sampling of potentially harmful bacteria. Images can be appended to a
patient’s clinical care record by exporting the images in JPEG format or printing them (see Section 9.9).

4.2 How MolecuLight i
i:
XCreates Images in FL-Mode
The MolecuLight i:Xincludes two high-efficiency violet wavelength emitting LEDs that illuminate wounds and surrounding
skin for high-resolution and real-time fluorescence imaging of bacteria and tissues, without the need for contrast agents.
When wounds are illuminated by violet light, endogenous collagens in the connective tissue matrix emit a green colored
fluorescent signal. Some bacteria emit a red colored fluorescence signal due to the production of endogenous porphyrins,
and others emit a cyan colored fluorescence signal due to the production of endogenous pyoverdine. The MolecuLight i:X
Imaging Device simultaneously captures fluorescence from both bacteria and tissues and creates a composite image on the
high-resolution color LCD Display Screen. The user can easily and instantly visualize the presence and location of bacteria
within and around a wound.
Figure 3 illustrates how MolecuLight i:Xuses violet light illumination to create real-time fluorescence images.
Caution
Keep the Illumination Zone clean and avoid covering the Violet Wavelength LEDs and camera sensor
window with your fingers, as this may affect illumination and image quality (see Figure 2, item 15).
Note
The red color may appear orange to some users
.
Figure 3: MolecuLight i:XReal-time Imaging
Violet Wavelength LEDs homogeneously illuminate the wound, resulting in the generation of a red or cyan fluorescence
signal when bacteria are present due to the presence of endogenous porphyrins or pyoverdine.

10 Measuring Wound Area
The iX Camera App wound measurement functionality features wound border detection, wound area measurement, and
wound length & width measurement capabilities. The wound border may be traced automatically (Auto Mode) or manually
(Manual Mode). Wound area measurement should only be performed on images captured in Standard Imaging Mode with
the use of MolecuLight WoundStickers. Refer to Appendix E for additional details on the iX Camera App wound
measurement functionality.
Note
The wound measurement functionality should only be used on images captured in Standard Imaging
Mode and should not be used on images captured in Fluorescence imaging mode.
Note
The use of 2 MolecuLight WoundStickers may produce an average wound measurement error (Area
and Dimension)
of 5%, when the image is taken with MolecuLight WoundStickers in the plane of the
wound.
Note
In the absence of MolecuLight WoundStickers, no
area measurement is provided.
Caution
The use of only 1 MolecuLight WoundSticker may produce an average wound measurement error (Area
and Dimension) of 15%, when the image is taken with MolecuLight WoundStickers in the plane of the
wound.
Caution
Only MolecuLight WoundStickers should be used for the wound measurement functionality.
Caution
Do not place MolecuLight WoundStickers on the wound.
10.1 Settings Menu
The Settings Menu accessed from the Menu Bar enables customization of the wound border thickness, and display of
reported length and width dimensions. The Album feature may also be enabled through the Settings Menu as
described in Section 9.5.
10.1.1 Wound Border Thickness
The displayed wound border thickness can be modified from the Settings Menu
accessed from the Menu Bar.
By default, the medium border thickness is selected.
Use the slider to modify the border thickness to the desired setting.
The 3 available settings are
1) Thin
2) Medium
3) Thick
10.1.2 Display of Length & Width Dimensions
The display of the Length and Width dimensions can be disabled or enabled using the switch from the Settings Menu
accessed from the Menu Bar.
When enabled, a selection between “Length & Width” or “Vertical & Horizontal” can be made. By default, the “Length
& Width” setting is enabled where the maximum length and perpendicular width of the wound is displayed on screen
whenever a wound measurement is taken.
When display of dimensions is disabled using the switch from the Settings Menu , length/width or vertical/horizontal
dimensions will no longer be reported on the wound image when a wound border is drawn and saved.
MolecuLight i:XTM User Manual Revision 1.1 Page 34 of 43
10.1.2.1 Length & Width
By default, the Length & Width setting is enabled:
Once the desired wound border is drawn, Length & Width dimensions will appear as blue and
green lines on the wound and their measurements will be reported in cm.
Wound length (blue line, L) represents the longest dimension of the wound in any direction.
Wound width (green line, W) is drawn perpendicular to wound length.
As wounds change in size over time the orientation of the maximum length of the wound may
also shift and therefore the maximum length may not always be reported from the same part
of the wound using this length and width option.
10.1.2.2 Vertical & Horizontal
Wound dimensions are also available in vertical and horizontal format:
Vertical length (blue line, V) represents the longest vertical distance (top to bottom of the
screen) within the wound boundary. Horizontal length (green line, H) represents the longest
horizontal distance within the wound boundary.
Selecting this method of measuring wounds will allow you to consistently measure the same
axes of the wound for tracking changes in vertical and horizontal wound distances over time.
To measure the wound consistently, wound images must be taken with consistent orientation.
This method of measurement can be combined with the well documented clock method to
accurately detect changes in the vertical and horizontal distances of the wounds.
To take measurements according to the clock method, capture wound images with the
MolecuLight i:Xin a portrait orientation such that the top of the device is aligned with the head
of the patient and the bottom with the feet of the patient. The measured vertical distance will
be a measurement of the wound from 12-6 o’clock and the horizontal distance will be a
measurement of the wound from 9-3 o’clock.
10.2 Auto Mode
The iX Camera App can automatically trace and measure the area of a wound. The following steps are required for
automated wound area measurements:
1. Ensure the Standard Imaging Mode wound image is captured with 2 MolecuLight WoundStickers (P/N 1266) placed
close to and within the plane of the wound. Measurement accuracy will be degraded if the MolecuLight WoundStickers
are off plane, in which case stickers may appear elliptical. For optimal results, ensure the MolecuLight WoundSticker
placement is at the 1 and 7 o’clock position or at the 11 and 5 o’clock position when holding the MolecuLight i:Xin a
portrait (vertical) orientation, as depicted in Figure 22 and Figure 23.
2. When capturing an image, ensure the MolecuLight i:XCamera Sensor is parallel to the wound and the MolecuLight
WoundStickers are in field of view.
3. Open the image of interest from the Image Library . Select the Auto Trace icon.
4. The Auto Trace feature traces the border of the wound with a white line (the MolecuLight WoundStickers will be
highlighted with a blue circle during this auto detection process).
5. When selecting Auto Trace, additional icons are available to expand or contract the detected border. Pressing
these icons expands or contracts the wound border as desired.
6. Once the desired wound border is achieved, a Checkmark icon is available to ‘Accept and Save’ the wound border
and the wound area will appear in cm2.
At any point, the user can select the Auto Trace icon to exit Auto Mode.
Note
Once the user has pressed the Expand icon until it reaches the largest detection threshold range,
the Expand icon will disappear, leaving the Contract icon.

Note
Once the user has pressed the Contract icon until it reaches the smallest detection threshold
range, the Contract icon will disappear, leaving the Expand icon.
Note
T
he wound area measurement is not displayed unless the user selects the Checkmark icon.
10.3 Manual Mode
If Auto Mode is not tracing an accurate wound boundary, the iX Camera App also allows for manual tracing of the wound
border to measure wound area. The following steps are required for manual wound area measurements:
1. Ensure the Standard Imaging Mode wound image is captured with 2 MolecuLight WoundStickers (P/N 1266) placed
close to and within the plane of the wound. Measurement accuracy will be degraded if the MolecuLight WoundStickers
are off plane, in which case stickers may appear elliptical. For optimal results, ensure the MolecuLight WoundSticker
placement is at the 1 and 7 o’clock position or at the 11 and 5 o’clock position when holding the MolecuLight i:Xin a
portrait (vertical) orientation, as depicted in Figure 22 and Figure 23.
2. When capturing an image, ensure the MolecuLight i:XCamera Sensor is parallel to the wound and the MolecuLight
WoundStickers are in field of view.
3. Open the image of interest from the Image Library . Select the Manual Trace icon.
4. Use your index finger or a stylus to draw the border of the wound. Maintain contact with the Display Screen until
closing the wound border trace.
5. Select the Checkmark icon if the trace is acceptable.
6. If the trace is not acceptable, press the Manual Trace icon once to exit Manual Mode and press it again to reenter
Manual Mode.
7. Once the desired wound border is drawn, a Checkmark icon is available to ‘Accept and Save’ the wound border and
the wound area will appear in cm2.
Note
T
he wound area measurement is not displayed unless the user selects the Checkmark icon.
10.3 Saving a Wound Measurement
When a wound border is traced (in either Auto or Manual Mode), a Checkmark icon is available and when selected, a
pop-up message will appear prompting the user to ‘Accept and Save’ the image. The user should select ‘OK’ when the
wound border trace accurately represents the border of the wound. Once ‘OK’ is selected, the image with the wound
border, reported area measurement, and any length/width or vertical/horizontal dimensions (when enabled) will be saved
as a new image to the same Album as the original image.
11 Interpretation of Fluorescence Images
MolecuLight i:Xallows real-time visualization of the presence and distribution of bacteria in wounds (for more details, see
Sections 4.2 and 5). When the device is used in FL-Mode as described in Step 5 of the Quick Start Guide in Appendix C,
fluorescence images of a wound may be obtained.
The fluorescence images obtained with the MolecuLight i:XImaging Device have distinct fluorescence colors which are
associated with bacteria and other different wound components. Users may see the following characteristic fluorescence
colors when imaging wounds:
Color
Indicator
Red*
Typically associated with the presence of potentially harmful levels of bacteria
Green
Typically associated with connective tissues in skin
Dark/black areas
Typically associated with blood, highly vascularized tissues, necrotic tissue, highly pigmented tissue
(freckles, moles, etc.) or poorly illuminated areas
White
Typically associated with materials in the field of view that are white (bed sheet, clothing, paper,
wound measuring ruler, etc.) or oversaturation of color signal
Cyan
Typically associated with the presence of Pseudomonas aeruginosa
Table 13: Color indicators for interpretation of fluorescence images
MolecuLight i:XTM User Manual Revision 1.1 Page 36 of 43
Note*
Red color of bacteria may appear orange to some users.
Figure 24 provides examples of the Standard Imaging Mode (ST-Image) and corresponding Fluorescence Imaging Mode (FL-
Image) from typical diabetic foot ulcers (DFUs) showing the characteristic red and green fluorescence colors typically seen
during use of the MolecuLight i:XImaging Device for assessing a DFU.
11.1 Color Blindness
Correct interpretation of the images acquired with the MolecuLight i:XImaging Device requires that the user can
differentiate between green and red colors. A typical test for red-green color blindness involves looking at color swatches
(see the examples in Figure 25). Individuals who do not suffer from red-green color blindness will be able to see the number
56 in the left-hand color swatch shown below, and the number 74 in the right-hand color swatch shown below.
Figure 25: Color figure swatches used in a typical clinical color-blindness test
Caution

functioning properly. For further information, contact [e-mail].
xThe Rocker Switch may be set to imaging in Standard Imaging Mode.
15. What is the System Status LED?
xThis LED informs you that the device electronics and optics are functioning as designed. This LED should be
green. If the color changes to amber or red, contact MolecuLight as soon as possible. Refer to Section 6.1.1.1.
16. What does the Battery Status LED indicate?
MolecuLight i:XTM User Manual Revision 1.1 Page 40 of 43
xThis LED indicates the battery power of the device (for the optics and electronics) and is green when the charge
is >80%. Note that there is also a battery status for the Display Screen itself in the top right corner of the screen
that is independent of the device.
17. What does the Range Finder LED indicate?
xThe Range Finder notifies you when the optimal distance between the device and the wound is reached, i.e. 8-
12 cm. This is critical to follow in FL-Mode and it is also advised to observe the Range Finder LED when in ST-
Mode so that the images obtained will have a similar field of view.
18. How do I check if the Range Finder is working properly?
xYou can use a ruler at various distances from the device to verify the Range Finder LED Status. At a 5 cm
distance, the LED should be amber, at 10 cm, the LED should turn green and at 15 cm the LED should turn
amber again. If the results are incorrect, do not use the device and contact MolecuLight at
[e-mail] or call [phone] or 1-877-818-4360 (North America Only).
19. What does the Ambient Light Status LED indicate?

Ambient Light Status LED will notify you when conditions are optimal (the LED will be green).
20. How do I check if the Ambient Light Status LED is working?
xThe Ambient Light Status LED should be amber in a bright environment and turn green in a dark environment.
Make sure all lighting is off in order for the LED to turn green. If you have any questions, contact MolecuLight at
[e-mail] or call [phone] or 1-877-818-4360 (North America Only).
21. The Ambient Light Status LED turns off when the device is in FL-Mode. Is this intended?
xYes, this is the normal operation. The ambient light sensor which is used to measure the ambient light
conditions is also sensitive to the light emitted from the device during FL-Mode operation, therefore the
indicator LED turns off in this mode to ensure it does not provide a false reading. The lighting conditions should
be adjusted such that the Ambient Light Status LED is green prior to using FL-Mode.
xIf you are unable to obtain optimal ambient light for FL-Mode, MolecuLight recommends using MolecuLight
DarkDrape (used in conjunction with MolecuLight Adapter). For more information, refer to Section 4.3, or
contact MolecuLight at [email protected] or [phone] or 1-877-818-4360 (North America Only).
22. How do I know that my Device is working properly?
xThe System Status LED indicates the functionality of the electronics and optics of the device. This LED is green
when the device is turned on and operating properly. If it is amber or red, contact MolecuLight at
[e-mail].
23. How long does it take to charge the device?
xThe device charges to approximately 80% of its total capacity after 2 hours of charging and will be fully charged
after approximately 5 hours.
About operating the wound measurement app:
24. Why do I need to use the MolecuLight WoundStickers?
xIn the absence of MolecuLight WoundStickers, no area measurement is provided. The use of 2 MolecuLight
WoundSticker may produce an average wound measurement (area and/or dimension) error of 5%, when the
image is taken with MolecuLight WoundStickers in the plane of the wound. The use of only 1 MolecuLight
WoundSticker may produce an average wound measurement (area and/or dimension) error of 15%.
