4 DESCRIPTION OF THE DEVICE
The Disposable Thyroid Collar is a radiation protective shield for the thyroid intended to be used in various medical procedures where X-ray radiation is used. It is a non-sterile device, designed for single use. The device is constructed with environmentally friendly radiation attenuating materials, which do not contain lead or heavy metals. The radiation attenuating material is encased in a medical grade polypropylene (PP) non-woven drape material. The device is available in three sizes, small, medium, and large.
The device blocks radiation in a similar manner to lead - via absorption of the photon energy from ionizing radiation. This photon energy is dissipated as phonon energy within the atomic lattice structure of the radiation attenuating material, in a manner identical to lead.
น INDICATIONS FOR USE AND INTENDED USE
The BloXR Disposable Thyroid Collar has the following indications for use:
The Disposable Thyroid Collar is indicated for use as a radiation shield against scatter radiation. It is intended to be placed around the neck of the user who remains outside of the primary radiation beam.
This is the same intended use as the predicate devices.
The Disposable Thyroid Collar and the predicate devices all have the same intended use namely, to attenuate scatter radiation to protect the user. The BloXR Disposable Thyroid Collar and the predicate devices all share the same primary function; that is, to physically block ionizing radiation. All the devices provide a physical barrier to attenuate the ionizing radiation. Each device is worn by the users around their necks to provide protection from scatter radiation. Each device is available without a prescription and is intended to be used in a health care facility where ionizing radiation is in use.

6 TECHNOLOGICAL CHARACTERISTICS COMPARED TO THE PREDICATE DEVICES
The BloXR Disposable Thyroid Collar has the same design and shares many similar design characteristics to the predicate devices, the Cost Cruncher and the Starlite Thyroid Collars. All of the devices are available in a similar configuration to be worn easily around the neck; all of the devices include a mechanism to fasten the device around the neck.
All of the devices operate using the same fundamental scientific technology - they absorb the photon energy from ionizing radiation to provide protection. This photon energy is dissipated as phonon energy within the atomic lattice structure of the particulate absorber material. Each device, however, uses different materials to absorb the photon energy. The BloXR Disposable Thyroid Collar uses a proprietary material to absorb photon energy, which is encased in a polypropylene fabric. One of the predicate devices, the Cost Cruncher, uses a lead vinyl formula to absorb photon energy, whereas the Starlite uses a heavy-metal (lead-free) vinyl composite (details unspecified). Although they use different materials, each device is intended to provide a 0.5 mm lead equivalent protection. The BloXR Disposable Thyroid Collar is disposable whereas the predicate devices are reusable. The new device is provided disposable for hygienic and user preferences.
PERFORMANCE TESTING 7
The performance data presented in this 510(k) application demonstrate the BloXR Disposable Thyroid Collar is substantially equivalent to the predicate devices. The BloXR Disposable Thyroid Collar is made from materials with a known and established safe history of use in medical devices, which are suitable and safe for skin contact.
BloXR conducted two laboratory studies, one at an independent laboratory and the other inhouse, to evaluate and compare the radiation shielding properties of the device materials of the Disposable Thyroid Collar to the two predicate devices and to a 0.5 millimeter (mm) Jead sheet, as a control. The devices were tested at X-ray radiation levels of 60, 90, 100 and 120 K Vp using the methodology described in ASTM F 2547-06 "Standard Method for Determining Attenuation Properties in a Primary X-ray Beam of Materials Used to Protect against Radiation Generated during the Use of X-ray Equipment." The attenuation level provided by BloXR materials was similar to the predicate devices and the 0.5 mm lead sheet, demonstrating substantial equivalence.
8 CONCLUSIONS
This 510(k) submission demonstrates that the Disposable Thyroid Collar is substantially equivalent to the predicate devices.
