Hemoblock S (Prescription): For use as a temporary external dressing to control moderate to severe bleeding and manage external abrasions and lacerations

Hemoblock S (OTC): To control bleeding of minor lacerations, minor cuts and minor abrasions

Device Description

The Hemoblock_S (Hemoblock_S (Prescription Use) and Hemoblock_S (OTC Use)) for being placed on the U.S.A Market is single use, hemostatic dressing made of Chitosan and Cotton. This device is called to Hemoblock Gauze on the Republic of Korea Market.

Chitosan is a naturally occurring polysaccharide usually derived from shellfish, and its hemostatic properties are widely recognized in the biomedical field. When applied directly on a wound with firm pressure, the Hemoblock_S acts as a mechanical barrier against bleeding by turning into a gel-like condition to absorb the blood and assist in temporarily controlling moderate to severe bleeding. The Hemoblock_S is provided in two different types to accommodate a variety of treatment regions, according to being based on the whether strap yan which is consisted with Nylon and handle for remove a device into any wound, with following;

Gauze(N) Type: There is not strap yarn part on the Hemoblock_S
Gauze(S) Type: There is strap yarn part on the Hemoblock_S

The Hemoblock_S is individually packaged in a foil pouch and is Irradiation sterilized in accordance with ISO 11137 Series.

AI/ML Overview

The provided text does not contain information about the acceptance criteria and performance of a device based on a study; instead, it is a 510(k) premarket notification summary for a hemostatic dressing called "Hemoblock S". The document details the device's characteristics, its comparison to a predicate device, and non-clinical testing performed (biocompatibility, sterilization, shelf-life, and general performance tests like appearance, dimension, tensile strength, absorption, X-ray impermeableness, and in vitro blood clotting test). It also mentions an animal study for hemostatic testing.

There is no mention of a study involving a test set, data provenance, expert ground truth, adjudication methods, MRMC studies, standalone algorithm performance, or specific acceptance criteria with reported device performance in the context of diagnostic accuracy or AI assistance. The performance tests mentioned are related to the physical properties and sterilization of the dressing, not its diagnostic or assistive capabilities for human readers.

Therefore, I cannot fulfill the request as the provided text does not contain the necessary information regarding acceptance criteria and study results for device performance in the context of the questions asked.

Dear Milly An:

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 (the 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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to 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.

{7}------------------------------------------------

The indications for use for the predicate devices is substantially equivalent to the proposed indications for use for the Hemoblock_S. The technological characteristics of the Hemoblock_S are similar to the predicate devices. Available data, including biocompatibility test, sterilized validation and performance data, support the determination of substantial equivalence. Minor differences, such as size, sterilization method and shelf life, between both devices do not raise any new issues of safety or effectiveness. Thus, the Hemoblock_S is substantially equivalent to the predicate devices

7. Non-Clinical Testing

7.1 Biocompatibility Test

Biocompatibility Testing per ISO 10993-1 and FDA guidance ("Biological evaluation of medical devices-Part 1: Evaluation and testing within a risk management process") was performed for:

Nature of body contact		Contact Duration	Biological Effects-Test Items
Category	Contact
Surface devices	Breached orcompromised surface	A- limited (≤ 24h)	Cytotoxicity Test
			Sensitization
			Irritation orintracutaneousreactivity
			Material mediatedpyrogenicity
			Acute systemictoxicity

7.2 Sterilization and Shelf life

Hemoblock_S is supplied sterile in a foil bag. It is sterilized using Irradiation (E-beam) to a sterility assurance level (SAL) of 10-6 . E-beam sterilization was performed in compliance with the ISO 11137-1 and ISO 11137-2 and ISO 11137-3 standards.

Following the E-beam sterilization, the packaging was subjected to sterile barrier testing to validate a shelf life of three (5) years as per ISO and ASTM standards.

{8}------------------------------------------------

. The stability and effectiveness of packaging of the sterilized product during the shelf-life period was confirmed by real time stability studies and accelerated aging test, per ASTM F-1980
Package seal strength per ASTM F88/F88M
. Dye migration test as per ASTM F1929
. Sterility test as per ISO 11737-2.

7.3 Performance Test - Non clinical

The physical performance test results all meet the requirements of the acceptance criteria

. Physical Test
- Appearance
- Dimension
- Tensile Strength (ISO 9073-18)
- Absorption (EN 13726-1)
- Nylon Tensile Strength (ASTM D2256)
- X-ray impermeableness
Virus Inactivation Validation Report
- In Vitro Blood Clotting Test

7.4 Performance Test - Animal Test

In the animal study conducted, 12 females New Zealand white rabbit were randomly assigned for in vivo hemostatic testing.

8. Conclusion

The Hemoblock_S is substantially equivalent to the predicate device in terms of materials, technological characteristics, indications for use, and performance. No new issues of safety or effectiveness are raised by the Hemoblock S.
