Intended Use

The OneDose Patient Dosimetry System is intended to measure a patient's dose during radiotherapy applications.

Device Story

OneDose Patient Dosimetry System measures radiation dose during radiotherapy. System components: disposable, pre-calibrated, battery-powered, wireless dosimeters; reader; reader calibration test strip. Dosimeters utilize metal oxide semiconductor field effect transistor (MOSFET) sensing mechanism. Operation: dosimeter adhered to patient skin via medical-grade adhesive; after radiotherapy, dosimeter removed and inserted into reader; reader displays and stores dose data. Used in clinical radiotherapy settings. Benefits: wireless design eliminates cables on patient; pre-calibration improves user convenience; disposable nature avoids continuous re-use/archiving issues.

Clinical Evidence

No clinical data. Substantial equivalence supported by bench testing demonstrating that factory-calibrated devices perform within stated specifications and that the adhesive material is non-toxic, a non-sensitizer, and a non-irritant.

Technological Characteristics

Sensing mechanism: MOSFET. Power source: battery. Form factor: small, wireless, disposable, single-use dosimeter with medical-grade adhesive. Connectivity: reader stores data in memory. Calibration: factory-calibrated for thermal fluctuations.

Indications for Use

Indicated for patients undergoing radiotherapy applications to measure radiation dose.

Regulatory Classification

Identification

A medical charged-particle radiation therapy system is a device that produces by acceleration high energy charged particles (e.g., electrons and protons) intended for use in radiation therapy. This generic type of device may include signal analysis and display equipment, patient and equipment supports, treatment planning computer programs, component parts, and accessories.

Sun Nuclear K021463 and K011332 rf-IVD and rf-IVD PC version

Device Description:

The OneDose Patient Dosimetry System consists of the following components and accessories: (1) disposable, single use, pre-calibrated radiation dosimeters, and accounts ( ( ) a reader, and (3) a reader calibration test strip. (2) a hand hold, bakery powers, metal oxide semiconductor field effect transistor as a sensing mechanism. The dosimeters are inserted into the Reader and as a sonoing mochanie a patient. The dosimeters are small and have no wires. They have a medical grade adhesive and liner on the back. The liner is veroo. They have adhesive side of the dosimeter is adhered to the patient. Following radiotherapy, the dosimeters are removed from the patient, re-inserted into the Reader, and the patient's dose is read and reported by the Reader. The into the records are stored on the dosimeter for future reference and in the Reader's memory.

Indication for Use:

The OneDose Patient Dosimetry System is intended to measure a patient's dose during radiotherapy applications.

Comparison with Predicate Device:

The OneDose and the Thomson Nielsen Patient Dose Verification System (K010472, K032725) and the Sun Nuclear RF-IVD System (K011332 and K021463) have the same intended use and similar indications, principles of operation and similar technological characteristics. Both devices are intended for patient dosimetry. The Sun Nuclear device and OneDose are battery powered. The Thomson Nielsen device and the OneDose use a MOSFET as the sensing mechanism. The only technological differences between the OneDose and its predicates are: (1) the OneDose is not wired to a patient; (2) the OneDose is precalibrated; and (3) the OneDose is a disposable, single use device.

These differences do not present any new issues of safety or effectiveness because the OneDose is safer for the patient since there are no cables wired to the patient and the OneDose is more convenient for the user since it is pre

The OneDose, while pre-calibrated, is calibrated for thermal fluctuations in a The OneDoo, while pro callerater, is also provided by the methou similar to the outh Ractors built in. The OneDose is calibrated at the manufacturer with conceenship laction ball many on Nielsen for evaluating ractiation lactory using the same mothou are is calibrated under controlled conditions at the factory and the Thomson Nielsen device must be calibrated by the user. The the factory and the Thorneon Melescribed in sufficient detail within the 510(k) to lactory callbration procedureed to assure calibration and the data contained with demonstrate the mothers section demonstrates that calibrated devices perform within the stated performance specifications of the labeling.

The OneDose is a single use dosimeter and the used device may be archived or The Onoboos to a omgio continuous re-use of dosimeters like with other dosimetry thrown away volous on. 510(k) demonstrates that the adhesive used with the Systems: Data whillif it adhering to skin is a safe, medical grade material found to be non-toxic, a non-sensitizer, and a non-irritant.

Thus, the OneDose is substantially equivalent to the Thomson Nielsen Patient Dose Verification System (K010472, K032725) and the Sun Nuclear RF-IVD System (K011332 and K021463).
