The Medcomp® Power Injectable Huber Needle Safety Infusion Set is intended for use in the administration of fluids and drugs, as well as blood sampling through implanted vascular access ports. The Medcomp® Power Injectable Huber Needle Safety Infusion Set is also indicated for power injection of contrast media into the central venous system with implanted vascular access ports indicated for power injection. The maximum recommended infusion rate at 11.8 cPs is 5 ml/sec for 19 gauge and 20 gauge non-coring Huber style needles and 2 ml/sec for 22 gauge noncoring Huber style needles.
The Power Injectable Safety Huber Needle is composed of a sharpened anti-coring Huber style needle for port septum access having a safety feature which is manually operated and will prevent accidental needle sticks when advanced which is connected to a conventional style extension set for attachment to standard IV/Drug infusion line sets.
The proximal end of the needle cannula is adhesively sealed to the molded housing which contains a glue well and fluid thru hole thru hole leads to the distal end of the extension line set that is also adhesively bonded in the molded housing. The distal end of the extension tubing contains a female luer connector with removable dust cap on the proximal end creating a fluid path from the needle tip thru the female luer. The infusion set is also offered in a configuration where the extension tubing contains a Y-Site connector with removable dust cap placed midway between the needle and the female luer connector. The extension tubing contains purple pigment to indicate its use for high pressure. The Y portion of the connector is a molded female luer that is sealed with a removable dust cap. A non-removable pinch clamp is located between the female luer and needle cannula. On line sets with a Y-Site connector, two pinch clamps are present located between the female luer and the Y-Site and the Y-Site and the needle cannula. The pinch clamps are designed that when engaged, fluid flow is restricted thru the extension tubing.
The needle cannula is constructed with a Huber style anti-coring needle tip. The cannula is stainless steel and is shielded by a removable star needle guard of plastic construction.
The molded wing housing is of plastic construction and contains rigid protruding wings.
The molded wing housing is snap fitted into the molded housing via a securement post. The wing housing is of plastic construction with a protruding wing designed flush with the under surface of the housing. The wing housing contains a thru hole that easily slides over the needle cannula. The wing housing contains a torsion spring that is positioned on a post and is orientated in a positioning channel. The torsion spring is in a compressed state until the molded housing is removed from the wing housing at which time the torsion spring is automatically activated. The wing housing consists of a base to which the securement bag is adhesively bonded.
The molded housing is connected to the wing housing via the securement bag. The securement bag (a polyester film lamination) is adhesively bonded to the molded housing and the wing housing. The securement bag is compressed (accordion style) between the molded housing and wing housing and is of length sufficient to activate the torsion spring and to prevent the needle tip from entering the securement bag area.
In normal operation, the molded housing is activated during removal of the needle from the patient. The wing housing is held firmly in place while the molded housing is disengaged. The molded housing is disengaged from the wing housing by grasping the elevated portion of the molded housing and sliding the molded housing in an upward direction. The molded housing will disengage from the wing housing and will advance until the torsion spring is past the needle tip at which time the torsion spring will snap over the needle access hole. Upon spring activation, there will be an audible click sound as the spring snaps against the wing housing. The securement bag prevents the molded housing from advancing off the needle cannula and the torsion spring prevents the needle from advancing out of the housing.
Prior to use, the exposed portion of the needle cannula, including the sharpened needle tip area, is coated with a silicone fluid to render the needle lubricious and to reduce the insertion (penetration) and drag force to industry acceptable values.
Each needle size has I.D. Rings located within the pinch clamp to identify the appropriate infusion rate for the noted needle gauge size. Components will be assembled by the manufacturer into standard configurations with or without the "Y-Site" and packaged.
The provided text describes a medical device, the Medcomp Power Injectable Safety Huber Needle, and its FDA 510(k) clearance. However, the document does not contain the information requested in your prompt regarding acceptance criteria for a study proving device performance, sample sizes, expert qualifications, or details of efficacy studies (MRMC or standalone).
The document is a regulatory approval letter and a summary of the device for FDA submission. It focuses on demonstrating substantial equivalence to a predicate device rather than presenting detailed clinical study results with specific acceptance criteria and performance metrics.
Here's what can be extracted based on your request, highlighting the missing information:
1. Table of Acceptance Criteria and Reported Device Performance:
| Acceptance Criteria | Reported Device Performance |
|---|---|
| Not specified in the document. | Pressure ratings for each needle gauge size are determined through pressure testing. These ratings are located on the I.D. Ring within the infusion line clamp. (Specific values or pass/fail criteria are not provided). |
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):
- Sample Size: Not specified.
- Data Provenance: Not specified. The data appears to be from "Bench / Performance Data" (laboratory testing), not a clinical study.
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):
- Not applicable as this document does not describe a study involving expert-established ground truth for a test set. The performance data mentioned relates to engineering tests (pressure testing).
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:
- Not applicable. This document does not describe a study involving adjudication of a test set.
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:
- No. The document explicitly states: "Clinical studies were not deemed necessary since no changes have been made to the design, packaging, sterilization or indications for use that would have any effect on the safety and effectiveness of the device when compared to the legally marketed predicate device." This device is a physical medical needle, not an AI-powered diagnostic tool, so an MRMC study related to AI assistance would not be relevant.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- Not applicable. This device is a physical medical needle, not an algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc):
- For the "Bench / Performance Data" mentioned, the "ground truth" would be the direct measurements obtained from the physical pressure testing of the needles, adhering to established engineering standards relevant to pressure ratings for such devices. No medical "ground truth" (like pathology or expert consensus) is discussed for this type of device.
8. The sample size for the training set:
- Not applicable. This is not a machine learning or AI device that requires a training set.
9. How the ground truth for the training set was established:
- Not applicable. This is not a machine learning or AI device that requires a training set with established ground truth.
In summary, the provided document is a regulatory submission for a physical medical device (needle) and focuses on demonstrating substantial equivalence through bench testing, not on clinical efficacy studies with detailed acceptance criteria, expert reviews, or AI performance metrics as requested in your prompt.
