Design Specifications

The Lifebox Pulse Oximeter is designed for settings with inconsistent electrical power, as the charger protects the device from surges and the battery(3 AA Alkaline batteries or Lithium ion rechargeable battery) has a life of 14 hours in case of a power outage. It can be paired with two probes: a universal probe for 3+ months and a pediatric probe, both of which are included with the device purchase. The product has the following specifications: Pulse rate range: 25 - 250 bpm Resolution : 1 bpm It has a display type 2.4” color display 320 x 240 pixels with the following parameters on display; Digital SpO2, Pulse Rate, Pleth bar & SpO2 waveform    

Product Schematics

Technical Support

The first line of technical support is the instructional video, user manual, and troubleshooting guide. Additional support can be found by contacting the manufacturer.

Replacement Components

The product comes in a package that includes:

  • Pulse oximeter
  • Universal probe for 3+ months age
  • Pediatric probe
  • Pillow clip
  • Multi region charger
  • Multi language education DVD
These components can be replaced but the internal components of the oximeter cannot.

Lifecycle

2+ years for the oximeter, 1 year for the probes Sterilization (with a cloth and disinfectant) is required and described in the user manual. Some maintenance is also required. Instructions for both are provided in the user manual.

Manufacturer Specified Performance Parameters

Lifebox says their pulse oximeter

  • is suitable and sustainable for use under-resourced environments
  • is durable,
  • is able to survive severe voltage fluctuations when plugged in
  • has long-lasting battery for use during power outages
  • is easy to use
  • is inexpensive
  • is light and compact
  • is handheld
  • has a high resolution, 2.4” color display

Vetted Performance Status

There are no performance-specific accuracy data on this instrument. The accuracy of the Lifebox pulse oximeter is comparable to FDA-approved pulse oximeters designed for high income countries. The Lifebox oximeter was found to meet USA FDA 510(k) standards for the detection of hypoxia.

Safety

If surges more severe than  EN61000-4-5 +- 1KV line to line or +- 2KV line to ground are likely to occur, a surge protector should be used when charging the oximeter.  

Complementary Technical Systems

None

Compliance with regulations

The Lifebox Pulse oximeter complies with the World Health Organization and World Federation of Societies of Anesthesiologists standards for suitable application in under-resourced environments.  

Evaluation methods

The accuracy of the Lifebox pulse oximeter was compared against arterial hemoglobin oxygen saturation by academic researchers. It was also compared in accuracy to FDA-approved pulse oximeters.

    It is important to consider the battery life per charge cycle as resource constrained environments are constantly handling high volumes of patients and limited access to medical devices and staff. It would be ideal for the battery to last up to 8-12 hours or more to account for extended usage in these environments. It is also important to consider whether preventative maintenance is required throughout the 2 year lifetime of the product and the level of training that would be required for technical staff to perform on-site repairs. Additionally, if the probes are intended to be reusable than they must be able to be able to withstand cleaning methods used in the target settings.

  2. CarolineS_Fellow says:

    Academic literature and evaluation is extensive for a product designed for use in resource constrained clinic environments.

  3. CarolineS_Fellow says:

    Additionally, this product requires a reliable source of power.
