Intended Use
The B&J Manufacturing Ltd. MHH800 and MHH800SQ Deep Vein Thrombosis (DVT) Compression Devices are intended to increase venous blood flow in at risk patients in order to help prevent deep vein thrombosis.
Device Description
The Deep Vein Thrombosis (DVT) Pumps MHH800 and MHH800SQ are external pneumatic compression (EPC) devices that aid in the prevention of DVT from a potentially life threatening condition which can lead to pulmonary embolism. MHH800 and MHH800SQ are non-invasive mechanical prophylactic devices. The devices function as secondary pumps to propel venous blood for patients whose deep veins thrombosis must be prevented after surgeries in Orthopaedics etc. Additionally, the devices are reusable and can be used for more than one patient within its lifecycle. Model variations are distinguished by characters. MHH800 is without SQ, so the device means an intermittent pneumatic compression pump. MHH800SQ is with SQ, so the device means a sequential pneumatic compression pump. The two devices separately consist of an air pump and a soft pliable compression garment(s) for the foot, calf or thigh. For MHH800, the controller supplies compression on a preset timing cycle (12 seconds inflation and maintenance followed by 48 seconds of deflation) at a suggested pressure setting of 40 mmHg for the Leg and 120mmHg for the Foot. For MHH800SQ, the controller supplies compression on a preset timing cycle (12 seconds inflation followed by 48 seconds of deflation) at a suggested pressure setting, 45mmHg in the 1st chamber, 40 mmHg in the 2nd chamber and 30mmHg in the 3rd chamber for the Leg and 120mmHg for the Foot. The pressure in the garments is transferred to the extremity, augmenting venous blood flow when the leg is compressed, reducing stasis. This process also stimulates fibrinolysis; thus, reducing the risk of early clot formation. The DVT pumps produce automatically timed cycles of compressed air. This compressed air forces blood out of the deep veins, helping to prevent slowed or stopped blood flow. Bursts of air are delivered to the specially designed garments wrapped around extremities. This air helps to move blood out of the deep veins and reduce the risk of developing DVT. Garments are lined with tricot fabric to help reduce heat and perspiration.
More Information

No
The device description details a purely mechanical and pneumatic system operating on preset timing cycles and pressures. There is no mention of adaptive learning, pattern recognition, or any other characteristic typically associated with AI/ML. The performance studies focus on standard engineering and safety tests, not AI/ML model validation.

Yes
The device is intended to prevent deep vein thrombosis and increase venous blood flow, which are therapeutic actions.

No

The device is a therapeutic device designed to prevent deep vein thrombosis by increasing venous blood flow, not to diagnose a condition.

No

The device description explicitly states it consists of an air pump and compression garments, which are hardware components. The device functions by delivering compressed air to these garments.

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

Here's why:

  • Intended Use: The intended use is to "increase venous blood flow in at risk patients in order to help prevent deep vein thrombosis." This is a therapeutic and preventative action performed directly on the patient's body.
  • Device Description: The device is described as an "external pneumatic compression (EPC) device" that applies pressure to the extremities. This is a physical intervention, not a test performed on biological samples outside the body.
  • Lack of IVD Characteristics: The description does not mention any of the typical characteristics of an IVD, such as:
    • Analyzing biological samples (blood, urine, tissue, etc.)
    • Providing diagnostic information based on laboratory tests
    • Using reagents or assays

The device functions by applying external pressure to the body to improve blood flow, which is a mechanical and physical intervention, not an in vitro diagnostic test.

Model variations are distinguished by characters. MHH800 is without SQ, so the device means an intermittent pneumatic compression pump. MHH800SQ is with SQ, so the device means a sequential pneumatic compression pump.

The two devices separately consist of an air pump and a soft pliable compression garment(s) for the foot, calf or thigh. For MHH800, the controller supplies compression on a preset timing cycle (12 seconds inflation and maintenance followed by 48 seconds of deflation) at a suggested pressure setting of 40 mmHg for the Leg and 120mmHg for the Foot.

It is clear that the technological characteristics differences discussed above do not affect the safety and the effectiveness of the MHH800 and MHH800SQ.

8.3 Non-clinical Testing

The following safety and performance tests were conducted to assess MHH800 and MHH800SQ DVT compression devices.

  • Biocompatibility
  • 0 Software validation
  • O Electromagnetic compatibility and electrical safety
  • O Reliability
  • O Performance
    • System level software
    • Pressure accuracy
    • Cycle time
    • Bladder burst

All the test results demonstrate MHH800 and MHH800SQ DVD compression devices meet the requirements of their predefined acceptance criteria and intended uses.

No clinical testing was used to support the decision of safety and effectiveness.
