Intended Use
Veinoflow SCD, LBTK-M-I 5006 is a system to prevent DVT (Deep Vein Thrombosis) by improving the blood velocity of patients. LBTK-M-I 5006 is indicated for Circulation Enhancement, Deep Vein Thrombosis Prophylaxis, Edema -Acute, Edema - Chronic, Extremity Pain Incident to Trauma or Surgery, Leg ulcers, Venous Stasis / Venous Insufficiency.
Device Description
Veinoflow SCD, Model LBTK-M-I 5006, is a pneumatic pump system that supplies compressed air to inflate garments that are attached to a patent's lower limbs. It consists of a pump controller, specially designed inflation and deflation garments for feet and legs, air supply tubes, and power line. The inflation and deflation garments have 3 types: ① leg garments, ② calf garments, ③ foot cuffs. The system offers sequential inflation and propels the vein blood from limb to heart, therefore enhancing the blood circulation. The controller can automatically detect the external garment type, and provides pressure correspondingly. The pressure value is preset and adjustable. The controller has a self test system, when there is any error, it will alarm both in visual and audio.
More Information

Not Found

No
The device description details a pneumatic pump system with preset and adjustable pressure, automatic garment type detection, and a self-test system. There is no mention of AI, ML, or any learning or adaptive capabilities based on patient data or other inputs beyond basic automation. The performance studies focus on electrical safety, EMC, and biocompatibility, not on algorithmic performance metrics typically associated with AI/ML.

Yes
The device is described as a system to prevent DVT by improving blood velocity and is indicated for conditions like DVT prophylaxis, edema, and venous insufficiency, all of which are therapeutic purposes.

No

The device is described as a pneumatic pump system designed to prevent Deep Vein Thrombosis (DVT) by improving blood velocity and enhancing circulation, not for diagnosing medical conditions. Its indications for use are prophylactic and therapeutic (e.g., DVT prophylaxis, edema, leg ulcers), not diagnostic.

No

The device description clearly states it is a "pneumatic pump system" consisting of a "pump controller, specially designed inflation and deflation garments, air supply tubes, and power line," which are all hardware components.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is to prevent DVT and treat various conditions by improving blood velocity through pneumatic compression. This is a therapeutic and preventative physical intervention, not a diagnostic test performed on samples from the body.
  • Device Description: The device is a pneumatic pump system that applies external pressure to the limbs. It does not involve analyzing biological samples (blood, urine, tissue, etc.).
  • Lack of IVD Characteristics: There is no mention of analyzing samples, detecting biomarkers, or providing diagnostic information based on in vitro testing.

IVD devices are specifically designed to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. The Veinoflow SCD does not fit this description.

All the leg garments, calf garments and foot cuffs are packaged in pairs. The controller can function properly in both situations either when connected to a one single leg garment/calf garment/foot cuff or one pair of leg garments/calf garments/foot cuffs, giving the end user more flexibility for prophylaxis options.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Non-clinical testing was conducted to demonstrate substantial equivalence to the predicate device K123830. The tests performed include:
Electrical safety: ANSI AAMI ES60601-1: 2005/(R)2012 And A1:2012, C1:2009(R)2012 And A2:2010/(R)2012 (Consolidated Text) Medical Electrical Equipment - Part 1: General Requirements For Basic Safety And Essential Performance (IEC 60601-1:2005, MOD).
EMC: ANSI AAMI IEC 60601-1-2:2014, Medical Electrical Equipment -- Part 1-2: General Requirements For Basic Safety And Essential Performance -- Collateral Standard: Electromagnetic Disturbances --Requirements And Tests.
Additional safety testing: IEC 62133-2 Edition1.0 2017-02 Secondary cells and batteries containing alkaline or other non-acid electrolytes - Safety requirements for portable sealed secondary cells, and for batteries made from them, for use in portable applications - Part 2: Lithium systems.
Biocompatibility testing: ISO 10993-5:2009/(R) 2014, Biological Evaluation Of Medical Devices -- Part 5: Tests For In Vitro Cytotoxicity. (Biocompatibility) and ISO 10993-10 Third Edition 2010-08-01, Biological Evaluation Of Medical Devices - Part 10: Tests For Irritation And Skin Sensitization. (Biocompatibility).
The conclusion is that the Veinoflow SCD is substantially equivalent to the predicate device K123830 based on these tests.
