No
The device description and performance studies focus on the physical properties and functionality of a negative pressure wound therapy dressing and its interaction with a pump. There is no mention of AI or ML in the intended use, device description, or testing summaries.
Yes.
The device is intended for wound management through the application of negative pressure, which involves removing fluids and infectious materials from various wound types, including chronic, acute, traumatic, and ulcers, indicating a direct therapeutic action on the body.
No
This device, Innomed NPWT Silicone Foam Dressing, is a wound dressing used for negative pressure wound therapy (NPWT) in conjunction with a pump. Its purpose is to remove fluids from wounds and assist in wound management. It does not diagnose any condition or disease.
No
The device description clearly outlines physical components like foam dressing, suction bell, and fixation film strips, indicating it is a hardware device.
Based on the provided text, the Innomed NPWT Silicone Foam Dressing is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use clearly states the device is for "wound management via the application of negative pressure to the wound, in order for the removal of fluids, including wound exudates, irrigation fluids, body fluids and infectious materials." This describes a therapeutic and fluid management function applied directly to a wound on the body.
- Mechanism of Action: The mechanism of action describes how the dressing and pump work together to apply negative pressure and remove fluids from the wound bed. This is a physical process applied externally to the body.
- Device Description: The description details the physical components of the dressing and how it functions in conjunction with a pump. There is no mention of analyzing samples of bodily fluids or tissues outside of the body for diagnostic purposes.
- Lack of IVD Characteristics: IVD devices are typically used to examine specimens (like blood, urine, tissue) in vitro (outside the body) to provide information for diagnosis, monitoring, or screening. This device does not perform such analysis.
The device is a wound dressing used in conjunction with a negative pressure wound therapy (NPWT) pump, which is a therapeutic medical device.

Device Description
Innomed NPWT Silicone foam dressing is a single-use device, as an accessory to VCare-1000-300S pump, manufactured by VR Medical Technology Co., Ltd. The NPWT Silicone foam dressing consists of silicone adhesive coated foam dressing attached with a suction bell and fixation film strips.
The silicone foam dressing is comprised of PU film, absorbent pad consisting of polyurethane (PU) foam, absorbent fibre and polyester fabric, a layer silicone adhesive is coated onto the entire surface.
The suction bell is comprised of a polyvinyl chloride drainage tubing with a polypropylene pinch clamp, a polypropylene luer taper, a bell shape dome made of polyvinyl chloride, a transparent poly urethane film coated with acrylic adhesive. The suction bell is attached on the silicone foam dressing surface.
Fixations film strips is composed of PU film coated with acrylic adhesive.
Machnism of Action: The silicone adhesive coated foam dressing is used to pack the wound bed and cover periwound area, and the fixation film strips are applied over the outside edges of the dressing to facilitate hold the silicone foam dressing in place and seal the wound bed area. The other end of the attached suction bell is connected to a canister attached to the negative pressure pump, VCare 1000-300S pump, and served as a conduit to transfer the wound exudate to the canister under negative pressure when the pump is turned on.
Innomed NPWT Silicone Foam Dressing is available in 10 sizes: SNPWT-1010 ( 10cm X 10cm ), SNPWT-1020 (10cm X 20cm ), SNPWT-1030 (10cm X 30cm ), SNPWT-1040( 10cm X 40cm ), SNPWT-1515(15cm X 15cm ), SNPWT-1520 (15cm X 20cm ), SNPWT-1530 (15cm X 30cm ), SNPWT-2020 (20cm X 20cm ), SNPWT-2025(20cm X 25cm ), SNPWT-2525(25cm X 25cm )

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Non-clinical Testing Summary: The following tests were performed to support the safety and effectiveness of the subject device:
Biocompatibility Testing:
- Cytotoxicity ISO 10993-5:2009.
- Irritation ISO 10993-10:2010 ●
- Sensitization ISO 10093-10:2010 ●
- Acute and subacute systemic toxicity- ISO 10993-11:2017
- Material mediated pyrogenicity ISO 10993-11:2017/USP ●
- Implantation ISO 10993-6:2016.
Bench testing:
Innomed NPWT Silicone Foam Dressing was evaluated under of bench tests, along with the predicate, to ensure the dressing can be used along with VCare 1000-300S pump regarding performance and functionality requirements and performs similarly as the predicates.
Test Parameters:
- Silicone adhesive peel strength (N/25cm): Subject Device (K202823) 0.51, Secondary predicate (K151436) 0.60. Comment: Similar.
- Water absorption: Subject Device (K202823) 7, Secondary predicate (K151436) 9. Comment: Similar.
- Moisture vapor transmission rate (MVTR): Subject Device (K202823) 699, Secondary predicate (K151436) 1112. Comment: The secondary predicate does not work with a canister, therefore the wound exudate removal is dependent on the MVTR and the ability to retain the wound exudate in the dressing (Fluid Handling Capacity).
- Fluid handling capacity: Subject Device (K202823) 4.7, Secondary predicate (K151436) 11. Comment: The secondary predicate does not work with a canister, therefore the wound exudate removal is dependent on the MVTR and the ability to retain the wound exudate in the dressing (Fluid Handling Capacity).
- Pressure distribution underneath the dressings in 72 hours under various negative pressure conditions: Subject Device (K202823) Meet the requirements, Secondary predicate (K151436) Meet the requirements. Comment: Similar.
- Alarming functions: Subject Device (K202823) Meet the requirements, Secondary predicate (K151436) Meet the requirements. Comment: Similar.
- Liquid pooling: Subject Device (K202823) No, Secondary predicate (K151436) No. Comment: Similar.
Clinical Testing: No clinical testing was required to support substantial equivalence.
Conclusion: The non-clinical tests demonstrate that the subject device is as safe, as effective and performs as well as the legally marked predicate devices.
