Here's a breakdown of the acceptance criteria and study information for the Autoject® II for glass syringe, based on the provided document:

Acceptance Criteria and Reported Device Performance

Note: The submission device generally meets or improves upon the performance of the predicate device. The only significant difference highlighted is the reduced maximum stress exerted on the syringe, which is an improvement.

Study Information

1. Sample size used for the test set and the data provenance:
   • The document does not specify the exact sample size for each individual test (e.g., number of devices tested for force, length, etc.).
   • The data provenance is from non-clinical performance data conducted by Owen Mumford Ltd in the United Kingdom. It is a retrospective comparison against an existing predicate device.
2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
   • This information is not provided in the document. The tests seem to be objective engineering and performance verification tests rather than human-expert-based evaluations for ground truth.
3. Adjudication method for the test set:
   • This information is not applicable/provided as the tests are objective performance measurements, not based on expert adjudication.
4. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:
   • No, an MRMC comparative effectiveness study was not done. The device is a mechanical injection device, not an AI-powered diagnostic or assistive tool for human readers.
   • The document explicitly states: "Clinical performance data has not been submitted, and is therefore not included in this Special 510(k) document."
5. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
   • This question is not applicable as the device is a mechanical auto-injector, not an algorithm or AI system.
6. The type of ground truth used:
   • The "ground truth" for the performance comparisons comes from engineering specifications, physical measurements, and Finite Elemental Analysis (FEA) for the mechanical properties and operation of the device, directly compared to the predicate device's established performance.
7. The sample size for the training set:
   • This question is not applicable as the device is a mechanical auto-injector, not a machine learning model that requires a training set.
8. How the ground truth for the training set was established:
   • This question is not applicable as the device is mechanical and does not use a training set.

The hand held device is intended to aid in the self-administration of drugs from a prefilled BD Hypak 1 ml disposable glass syringe. The device incorporates enlarged wings to facilitate gripping and a semi-automatic feature to remove the needle shield of the Hypak syringe.

The EZ Syringe O.T.C is a hand held, non-sterile manual device using 1 ml BD Hypak disposable glass pre-filled syringe. The devices are designed for use with the 1 ml BD Hypak disposable glass syringe, and to accommodate self- use in the home by the patient or caregiver. The device incorporates enlarged wings to facilitate gripping and a semi-automatic feature to remove the needle shield of the Hypak syringe. The device contains a number of features which adds to its safety and effectiveness, these are as follows :- - Parking Action of Boot Remover. - Drop Test. - Environmental .

Here's an analysis of the provided text regarding the EZ Syringe, outlining what can be extracted about its acceptance criteria and study information:

Acceptance Criteria and Device Performance for EZ Syringe

Based on the provided documents, the information about acceptance criteria and device performance is limited. The documents mention that "A number of tests have been performed proving the correct action of a wide range of functions for the EZ Syringe," and that "The performance testing completed under section 6 of this 510(K) submission indicates that the device performs within the agreed specification and is safe and reliable." However, the specific acceptance criteria (e.g., minimum percentage successful needle shield removal) and their corresponding reported performance values are not explicitly detailed in the provided text.

The information on the tests performed is:

Note: The phrase "Proving the correct action" and "Clearly indicates the success of the device" are broad statements and do not provide quantifiable performance metrics or pre-defined acceptance thresholds. The full details would likely be in "section 6 of this 510(K) submission," which is not included.

Study Details:

1. Sample size used for the test set and the data provenance (e.g., country of origin of the data, retrospective or prospective):

   • Test Set Size: Not specified in the provided text.
   • Data Provenance: Not specified in the provided text. It is a 510(k) submission to the FDA (USA), but the origin of the testing data itself is not mentioned. It is also unclear if the studies were retrospective or prospective.

2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g., radiologist with 10 years of experience):

   • Not specified in the provided text. The "User Trial" involved "patient or carer preference," which implies users, not necessarily experts establishing ground truth in a clinical sense.

3. Adjudication method (e.g., 2+1, 3+1, none) for the test set:

   • Not specified in the provided text.

4. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:

   • No. This device (EZ Syringe) is a mechanical aid for self-injection, not an AI-powered diagnostic or interpretive tool. Therefore, a multi-reader multi-case comparative effectiveness study with AI assistance is not applicable.

5. If a standalone (i.e. algorithm only without human-in-the loop performance) was done:

   • Yes, implicitly for the mechanical tests. The "Parking Action of Boot Remover," "Drop Test," and "Environmental" tests would have assessed the device's function independently of a human user's performance, focusing on the device's inherent mechanical properties and durability. However, the "User Trial" involved human interaction (patient/carer preference).

6. The type of ground truth used (expert consensus, pathology, outcomes data, etc):

   • For the mechanical tests (Parking, Drop, Environmental), the ground truth would be based on engineering specifications and successful execution of the defined actions.
   • For the "User Trial," the ground truth or assessment metric was "patient or carer preference," which is a subjective assessment of usability and satisfaction.

7. The sample size for the training set:

   • Not applicable. This is a mechanical device, not an AI model that requires a training set.

8. How the ground truth for the training set was established:

   • Not applicable. This is a mechanical device, not an AI model.
