MolecuLight i:X Wound Imaging in St. Louis

MolecuLight i:X is a portable imaging device that detects fluorescence in bacteria in wounds. It contains a rechargeable battery and a touch-sensitive color LCD screen. In both normal imaging and fluorescent imaging modes, it can capture real-time snapshots and videos.

The technician can switch between modes by pressing a button on the gadget. Imaging is conducted at a distance of about four to five inches from the wound.

How MolecuLight i:X Works

The images are used to detect fluorescent bacteria and are shown at the point of care. When treated, this aids wound closure. The procedure also determines the length, breadth, and area of a wound. To identify the wound boundary, WoundStickers are inserted on opposing sides of the wound.

The MolecuLight i:X process involves emitting a violet light at a specific wavelength. This interacts with the bacteria and injured tissue. It produces a green glow in the wound and surrounding skin (due to collagen), as well as a red or cyan fluorescence in potentially hazardous bacteria (because of the production of porphyrins or pyoverdine by bacteria).

MolecuLight i:X captures these fluorescence signals and displays them on a screen for a medical specialist to assess.

Used in Conjunction with MolecuLight i:X

MolecuLight i:X is designed to work with a number of accessories, including:

  • WoundStickers, which are positioned close to the wound to measure the surface area. These stickers can be used in the conventional imaging mode.
  • DarkDrape, a built-in adaptor designed for obtaining the best possible image for when the lights in the room can't be switched off. DarkDrape is connected to MolecuLight i:X through an adapter device.
  • Optical lens wipes for cleaning the display screen and visible components in between uses.

Overall, the purpose of MolecuLight i:X is to aid wound evaluation by concentrating cleansing, debriding, and swabbing of the area where bacteria are present. It also aims to enhance antibiotic stewardship and optimize the timing of infected wound therapy.

Frequently Asked Questions

Here are some of the questions we most often receive in regard to MolecuLight i:X. To learn more, please contact our medical staff directly.

Why is wound imaging for bacteria important?

Bacteria are found just about everywhere, even on our skin. Bacteria that dwell on our bodies are mostly harmless and may actually help us live healthy lives.

Bacteria that have grown to a large level in a wound, on the other hand, might hinder it from healing and can often lead to complications, such as infection.

The MolecuLight i:X is used by a wound care expert to determine where and how germs are present in the wound. This aids medical professionals in determining the best treatment moving forward.

What bacteria can be detected by MolecuLight i:X?

Preclinical research has shown that the following species may emit noticeable red fluorescence:

Gram negative aerobic species

  • Pseudomonas aeruginosa
  • Escherichia coli
  • Proteus mirabilis
  • Proteus vulgaris
  • Enterobacter cloacae
  • Serratia marcescens
  • Acinetobacter baumannii
  • Klebsiella pneumoniae
  • Klebsiella oxytoca
  • Morganella morganii
  • Stenotrophomonas maltophilia
  • Citrobacter koseri
  • Citrobacter freundii
  • Aeromonas hydrophilia
  • Alcaligenes faecalis
  • Pseudomonas putida

Gram positive aerobic species

  • Staphylococcus aureus
  • Staphylococcus epidermis
  • Staphlyoccus lugdunensis
  • Staphylococcus capitis
  • Corynebacterium striatum
  • Bacillus cereus
  • Listeria monocytogenes

Anaerobic species

  • Bacteroides fragilis
  • Clostridium perfringens
  • Peptostreptococcus anaerobius
  • Propionibacterium acnes
  • Veillonella parvula

What are the clinical benefits of undergoing MolecuLight i:X?

The procedure is performed at the point of treatment to assist wound care practitioners in optimizing all wound procedures, including increased sample accuracy, more effective wound cleansing and debridement, plus dressing and antimicrobial selection.

The i:X can not only help improve these processes, but it can also help monitor the efficacy of treatment plans in reducing bacterial load and wound size. If the patient is not responding to the existing treatment strategy, your physician can adjust the treatment plan.

Why is fluorescence imaging performed in the dark?

Fluorescence imaging with the MolecuLight i:X needs a dark environment in order to properly identify germs. The apparatus requires darkness to observe fluorescence signals released by bacteria and other biological components in a wound.

Is the violet light emitted by the MolecuLight i:X safe?

Absolutely. The i:X uses violet light, which is safe to be around, rather than ultraviolet (UV) light to illuminate bacteria. The i:X device is a Risk Group 1 device, and the laser is a Class 1 laser. This signifies that the gadget does not generate enough energy to harm skin or eyes in typical usage.

It is not necessary to use safety glasses. However, it is not recommended that the gadget be pointed directly into the eyes.
