The proposed device is indicated for use as a dispenser, a measuring device, and a fluid transfer device. It is used to deliver fluids into the gastrointestinal system of a patient who is physically unable to eat and swallow. The enteral syringes are intended to be used in clinical or home care setting by users ranging from laypersons (under the supervision of a clinician) to clinicians, in all age groups.
The proposed device is a disposable enteral feeding syringe provided in a variety of sizes from 1ml~60ml. This device incorporates a female ENFit connection to an enteral access device with male ENFit connector.
The propsoed syringe is sterilized by Ethylene Oxide Gas to achieve a SAL of 10 and supplied sterility maintenance package which could maintain the sterility of the device during the shelf life of five years.
This document describes the non-clinical testing performed to demonstrate that the ENFit Enteral Syringe meets its acceptance criteria and is substantially equivalent to a predicate device.

2. Sample size used for the test set and the data provenance
The document does not explicitly state the specific sample sizes (number of units tested) for each non-clinical test. However, it indicates that "Non clinical tests were conducted to verify that the proposed device met all design specifications" and that "Connector testing performed on the proposed device included the items listed below, in accordance with ISO 80369-3:2016... using the test methods provided in ISO 80369-20..." and similarly for syringe testing. These standards often specify minimum sample sizes for different tests.
The data provenance is from non-clinical (bench) testing performed on the proposed device. The device manufacturer is Jiangsu Caina Medical Co., Ltd. located in Jiangyin, Jiangsu, China. The report is a summary of these tests. This is retrospective in the sense that the tests were completed prior to this submission.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
This section is not applicable as the information provided pertains to non-clinical (bench) testing of a medical device (enteral syringe). "Ground truth" and "experts" typically refer to human interpretation or pathology results in diagnostic or clinical studies. For physical device testing, the "ground truth" is defined by the technical specifications and requirements within the cited international standards (e.g., ISO, ASTM, USP).
4. Adjudication method for the test set
This section is not applicable as adjacency methods are used in clinical studies with human readers, not in non-clinical bench testing. The compliance is determined by whether the device's physical and performance characteristics meet the quantitative and qualitative requirements of the listed 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
This section is not applicable. An MRMC comparative effectiveness study is used for evaluating diagnostic or screening tools, often involving artificial intelligence. This document describes the non-clinical testing of a physical medical device (enteral syringe).
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done
This section is not applicable. "Standalone performance" in this context refers to the performance of an algorithm without human intervention, typically in AI/software as a medical device. This document is about a physical medical device.
7. The type of ground truth used
For the non-clinical tests, the "ground truth" is compliance with established international and national standards and their specified test methods and acceptance criteria. This includes:
- Performance Specifications: Defined by standards like ISO 80369-3, ISO 7886-1 for connector and syringe function (e.g., fluid leakage, tolerance on graduated capacity).
- Biocompatibility Standards: Defined by ISO 10993 series for biological safety (e.g., cytotoxicity, irritation, sensitization).
- Sterilization and Packaging Standards: Defined by ISO 10993-7, ASTM F 88/F88M-09, ASTM F1140/F1140-13, USP37-NF32 <85>.
8. The sample size for the training set
This section is not applicable. "Training set" refers to data used to train machine learning models. This document describes the non-clinical testing of a physical medical device.
9. How the ground truth for the training set was established
This section is not applicable.

Product Comparison Summary
The proposed device and predicate device are intended for patients who require enteral nutrition due to illness or injury which prevents normal chewing and swallowing. These products are enteral syringes that have the same smalll-bore connector, similar intended use and product specification
The difference between the proposed device and predicate device is the size of the syringe; both the proposed device and the predicate device comply with the relevant international Standards. Therefore the differences on syringe size will not raise new problems on safety and effectiveness of the proposed device.
8. Substantially Equivalent (SE) Conclusion
Based on the comparison and analysis above, the proposed devices are determined to be Substantially Equivalent (SE) to the predicate device.
§ 876.5980 Gastrointestinal tube and accessories.
(a)
Identification. A gastrointestinal tube and accessories is a device that consists of flexible or semi-rigid tubing used for instilling fluids into, withdrawing fluids from, splinting, or suppressing bleeding of the alimentary tract. This device may incorporate an integral inflatable balloon for retention or hemostasis. This generic type of device includes the hemostatic bag, irrigation and aspiration catheter (gastric, colonic, etc.), rectal catheter, sterile infant gavage set, gastrointestinal string and tubes to locate internal bleeding, double lumen tube for intestinal decompression or intubation, feeding tube, gastroenterostomy tube, Levine tube, nasogastric tube, single lumen tube with mercury weight balloon for intestinal intubation or decompression, and gastro-urological irrigation tray (for gastrological use).(b)
Classification. (1) Class II (special controls). The barium enema retention catheter and tip with or without a bag that is a gastrointestinal tube and accessory or a gastronomy tube holder accessory is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 876.9.(2) Class I (general controls) for the dissolvable nasogastric feed tube guide for the nasogastric tube. The class I device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to § 876.9.
