Flexicare's HepaShield Bacterial Viral Breathing System Filters are single patient for use on a single patient for up to 24hrs and are available in Adult size. FlepaShield Bacterial Viral Breathing System Filters are designed to be used in hospital environments by trained personnel.
Flexicare's HepaShield Bacterial Viral Breathing System Filters are designed to reduce the transmission of bacteria and viruses to and from a patient who requires aesthesia, artificial respiration or other types of assisted respiration
Flexicare's HepaShield Bacterial Viral Breathing System Filters consist of a top/bottom housing, pleated paper filter pack and a luer port cap. The Female luer-lock port allows connection of a luer-terminating monitoring line for monitoring of patient exhaled CO2 & is supplied with a tethered cap to seal port when not in use.
The patient side of the Flexicare's HepaShield Bacterial Viral Breathing System Filters feature a 22mm Male and a 15mm Female conical. The machine side features a 22mm Female and a 15mm Male conical.
All conical connectors comply with dimensions stated within BS EN ISO 5356-1 standard.
Flexicare's HepaShield Bacterial Viral Breathing System Filters are available in Adult sizes.
Flexicare's HepaShield Bacterial Viral Breathing System Filters are available in a both Sterile and non-sterile state, packaged in individually sealed polybags, or blister trays (if sterile).

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
The document primarily refers to non-clinical bench testing and adherence to consensus standards. It does not provide specific sample sizes for each test beyond stating that the device "passed all performance tests." The data provenance is from laboratory testing performed by Flexicare, likely at their facilities in the UK or a contracted lab. This is prospective testing as it's part of the premarket notification process for a new device.
The document implicitly indicates that testing was done in accordance with international standards (e.g., ISO, EN ISO, ASTM, USP), which are globally recognized, but the specific country of origin for the data generation would be the UK or the location of any contracted testing laboratories.
3. 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)
This is a medical device (filter), not an AI or diagnostic imaging device. Therefore, the "ground truth" is established through objective physical and biological measurements in a laboratory setting based on recognized international standards. There are no human experts "establishing ground truth" in the same way as for diagnostic image interpretation. The expertise lies in the engineers and technicians performing the tests and interpreting the results against the defined standards.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable. This is not a study involving human interpretation or subjective assessments that would require an adjudication method. The tests are objective measurements against defined criteria in standards.
5. 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
Not applicable. This is a physical medical device (filter), not an AI-assisted diagnostic tool.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done
Not applicable. This is a physical medical device (filter), not an algorithm. The testing described is for the standalone performance of the filter.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
The "ground truth" for this device is based on objective, quantifiable physical and biological measurements as defined by recognized international standards (e.g., ISO, ASTM, EN ISO, USP) for filtration efficiency, pressure drop, biocompatibility, connector compliance, and mechanical integrity.
8. The sample size for the training set
Not applicable. There is no AI component or "training set" for this physical device.
9. How the ground truth for the training set was established
Not applicable. There is no AI component or "training set" for this physical device.
