The Practix Convenio is a mains independent motor driven mobile x-ray system, to x-ray body parts of patients to create images for medical diagnostic purposes. The Practix Convenio is intended to x-ray in rooms for medical use.

Device Description

The Practix Convenio is a motor driven battery supplied mobile x-ray unit to be operated indoors only. The system contains: Battery cluster including battery charger, two passive and two motor driven wheels, 20 kHz converter x-ray generator excluding the high voltage unit, 360° turn able column and a telescope arm to carry x-ray unit, x-ray tank (x-ray tube housing assembly and high voltage unit), collimator (beam limiting device) and a drawer to carry x-ray film cassettes and an anti scatter grid. The following components are optional: Removable pre filter, dose area product measurement, automatic exposure control and an infrared remote control.

AI/ML Overview

This document is a 510(k) summary for the Practix Convenio, a mobile x-ray system. It describes the device, its intended use, and compares it to a predicate device. However, it does not contain any information about acceptance criteria or a study proving the device meets those criteria, nor does it provide details on device performance metrics, sample sizes, expert involvement, or ground truth establishment.

The 510(k) process primarily focuses on demonstrating substantial equivalence to a legally marketed predicate device, rather than requiring extensive clinical performance studies with detailed acceptance criteria in the same way a PMA (Pre-Market Approval) submission would.

Therefore, I cannot fulfill your request for the specific information regarding acceptance criteria and a study to prove they are met based only on the provided text.

Here's why and what kind of information is missing:

Information NOT available in the provided text:

A table of acceptance criteria and the reported device performance: The document only describes the device and its intended use, not specific performance metrics or acceptance thresholds.
Sample size used for the test set and the data provenance: There is no mention of a specific test set or clinical study.
Number of experts used to establish the ground truth for the test set and the qualifications of those experts: As no test set is described, neither are experts or ground truth establishment.
Adjudication method for the test set: No test set is described.
If a multi-reader multi-case (MRMC) comparative effectiveness study was done, and the effect size: No such study is mentioned.
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: This device is a hardware system, not an AI algorithm, so this concept doesn't directly apply.
The type of ground truth used: No ground truth is discussed.
The sample size for the training set: No training set is discussed or implied.
How the ground truth for the training set was established: No training set is discussed.

Summary of what the document does provide:

Device Name: Practix Convenio
Intended Use: "The Practix Convenio is a mains independent motor driven mobile x-ray system, to x-ray body parts of patients to create images for medical diagnostic purposes. The Practix Convenio is intended to x-ray in rooms for medical use."
Predicate Device: RT-125 ROUGH TERRAIN MOBILE X-RAY UNIT (also known as PMX 2000) by Lorad (K894643)
Claim of Equivalence: "The Practix Convenio does not introduce any new indications for use, nor does the use of the device result in any new potential hazard. Philips Medical Systems considers the Practix Convenio to be substantially equivalent with the predicate device."
Regulatory Decision: The FDA determined the device is substantially equivalent, allowing it to be marketed.

To answer your full request, you would need different documentation, such as a more detailed technical report, design verification and validation reports, or clinical study protocols and results, which are not part of this 510(k) summary.

Dear Ms. Harmer:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act): 21 CFR 1000-1050.
