Intended Use

The ReliefBand is indicated for use in the treatment of nausea and vomiting (NV) due to chemotherapy, motion sickness, and pregnancy.

Device Story

ReliefBand is a non-invasive nerve stimulation device worn on the wrist; treats nausea and vomiting (NV) via electrical stimulation of the P6 acupuncture point. Device consists of a wristband worn on the ventral or palmar surface of the wrist between the palmaris longus and flexor carpi radialis tendons. Operation involves three pulse amplitude modulation modes (burst/off sequences) and six intensity levels selected by the patient. Powered by silver oxide or zinc-air batteries. User interface displays mode and intensity. Provides symptomatic relief for chemotherapy-induced, motion-related, and pregnancy-related NV. Intended for patient self-use.

Clinical Evidence

Bench testing only. Performance data indicates the device meets functional requirements and specifications for acustimulation of the P6 point.

Technological Characteristics

Non-invasive nerve stimulation device; wrist-worn form factor. Powered by three silver oxide (type 392/IEC SR41) or zinc-air (type 312/IEC PR41) batteries. Features three pulse amplitude modulation modes and six intensity levels. User display for mode/intensity selection. Not waterproof.

Indications for Use

Indicated for treatment of nausea and vomiting (NV) due to chemotherapy, motion sickness, and pregnancy in patients requiring acustimulation therapy.

Regulatory Classification

Identification

A transcutaneous electrical nerve stimulator for pain relief is a device used to apply an electrical current to electrodes on a patient's skin to treat pain.

#### 19.4 DEVICE DESCRIPTION

The ReliefBand® Model SW-111 is a non-invasive nerve stimulation therapy device, and is indicated for use in the treatment of nausea and vomiting (NV) due to chemotherapy, motion sickness, and pregnancy. The device is contained within a wristband, and provides relief of NV through electrical stimulation of the P6 acupuncture area on the patient's wrist.

This acustimulation wrist band can be worn on either hand on the ventral or palmar (i.e., inside) surface of the wrist, approximately 2-3 fingers breadth above the distal skin crease of the wrist joint between the tendons of the palmaris longus and flexor carpi radialis muscles.

There are three operating modes based on pulse amplitude modulation scheme:

- 2 second burst, 6 seconds off. This is the first setting in the 3 mode Mode A: sequence.
- Mode B: 4 second burst. continuous. This is the second setting in the 3 mode sequence.
- 2 second burst, continuous. This is the third setting in the 3 mode Mode C: sequence.

There are six intensity levels present for each of the three operating modes, and the intensity setting determines the strength of the stimulation. The user display on the wristband identifies both the operating mode and intensity level, so the patient can select the desired stimulation. The wristband is powered by either three silver oxide batteries (type 392/IEC SR41, 1.5 V), or three zinc-air batteries (type 312/IEC PR41, 1.4V), and should not be immersed in water.
