Uni-Patch Softy Model 699 Electrodes — 1.75" Square, Side Pin, 40/Pack

Uni-Patch™ Softy Model 699 Electrodes are compact, self-adhering electrotherapy pads that work with TENS, NMES, EMS, and FES stimulation systems.

Each electrode measures 1.75 × 1.75 inches and combines a soft, flexible foam backing with reinforced conductive solid gel. The smaller square footprint is useful where a standard 2 × 2-inch electrode may be larger than desired or where two electrode pads must fit within a more confined placement area.

This Balego package contains 40 electrodes and uses the EC89455 side-pin connection. Match the connector to the device’s lead wires before ordering.

The Model 699 is a self-adhering, reusable, soft-foam stimulating electrode for TENS, NMES, and FES.

The Softy 699 is a compact hydrogel-style stimulating electrode intended to carry electrical current from a compatible stimulator through the skin.

Its basic construction includes:

The product description highlights that the reinforced gel makes the whole electrode surface conductive and self-adhering, while the soft foam allows for comfortable, conformable placement.

The EC89455 is specifically the side-pin version of Model 699.

A compatible lead-wire pin inserts into the connection point at the side of the electrode. This differs from electrodes that use the following:

• A molded pigtail socket
• A metal snap
• A flat tab
• A proprietary plug
• A garment or wrap connection

Do not purchase electrodes based on shape and size alone. Connector compatibility is equally important.

A 1.75-inch square electrode has a slightly smaller footprint than the common 2 × 2-inch pad.

It may be useful when:

• The available placement area is limited
• Two pads must fit close to one another
• A smaller muscle or anatomical region is being targeted
• A clinician wants more focused placement
• A standard 2-inch square pad extends beyond the intended area
• A clinic is replacing an existing Model 699 setup

Electrode size affects current density. At the same stimulator output, a smaller pad can feel more concentrated than a larger electrode. Intensity should therefore be returned to zero whenever electrodes are changed, followed by gradual readjustment.

TENS, NMES, and FES are not interchangeable treatment goals even when they use similar electrode pads. Read TENS vs. NMES for a detailed comparison.

The Model 699 package contains 40 individual electrodes.

This package size may be useful for:

• Physical therapy clinics
• Occupational therapy departments
• Sports medicine practices
• Chiropractic rehabilitation
• Athletic training rooms
• Home-health organizations
• Clinician-managed home programs
• Facilities maintaining replacement inventory for existing Model 699 users

Follow the electrotherapy device manual, clinician instructions, and electrode packaging.

1. Turn the stimulator off and reduce every channel to zero.
2. Inspect the electrode, lead wire, and connector.
3. Clean and dry the treatment area.
4. Remove lotion, oil, perspiration, and debris.
5. Connect the lead-wire pin firmly to the side connector.
6. Lift the electrode from its liner by the foam edge.
7. Avoid pulling on the electrical connection.
8. Apply the entire gel surface to intact skin.
9. Press the edges down to obtain complete contact.
10. Turn on the stimulator.
11. Increase the intensity slowly.
12. Stop for sharp, burning, painful, or irregular stimulation.

The full electrode surface should remain in contact with the skin.

Poor contact can result from:

• Dry or worn conductive gel
• A lifted corner or edge
• Hair beneath the pad
• Lotion or oil on the skin
• Perspiration
• A damaged side-pin connector
• Excessive movement
• Placement over an uneven surface
• A pad that is too large or too small for the area

A concentrated stinging sensation beneath one portion of the electrode may indicate incomplete contact. Turn the device off before inspecting or repositioning the pad.

The Model 699 is reusable, and the FDA record’s structured data does not designate it as a single-use product. Reusable electrodes should nevertheless be assigned to one patient only and maintained according to the package directions.

Do not share electrodes between patients.

Electrode life varies with:

• Skin preparation
• Skin oil and perspiration
• Body hair
• Treatment location
• Frequency of application
• Storage conditions
• Handling technique
• Gel condition
• Exposure to heat or air

Replace an electrode when it no longer provides secure, even contact.

Do not add water, conductive gel, adhesive spray, or another substance unless the electrode manufacturer expressly permits it.

Replace an electrode when:

• It repeatedly lifts from the skin
• The gel has dried
• Adhesion cannot be restored through permitted care
• Stimulation feels sharp or uneven
• The foam is torn
• The electrode has become permanently folded
• The conductive layer appears damaged
• The side-pin connection has loosened
• The electrode produces intermittent output
• The pad has become contaminated
• The electrode has been used by another person

A visibly intact pad may still need replacement when its stimulation or adhesion becomes inconsistent.

Choose Model 699 when the smaller footprint, EC89455 side-pin connector, or exact legacy product is required.

Choose Balego electrodes when a currently supported, American-made pigtail/socket pad with multiple size options is preferred. Balego’s electrodes are offered in 2-inch square, 2-inch round, 2 × 3.5-inch rectangle, 2.75-inch round, and 1.25-inch round sizes.

The R Series is a better choice when the buyer wants several shapes and sizes, a conventional pigtail connector, and smaller four-electrode retail packages.

Classic electrodes are preferable when aloe hydrogel, a silver/carbon conductive layer, or larger pad shapes are desired.

A tab lead cannot attach directly to Model 699 unless a compatible adapter has been specifically approved. Balego’s connector guide emphasizes matching the electrode type to the device and lead-wire system. (Balego)

Browse our complete electrotherapy electrode collection for additional sizes, shapes, connector styles, and package quantities.

Customers who require Model 699 should confirm the following:

• That EC89455 is the exact connector required
• The quantity needed for an ongoing program
• Whether a future substitute is acceptable
• Which current Balego electrode most closely matches the device and treatment setup

Balego should present the product as remaining or legacy inventory if Cardinal Health confirms that the item is no longer manufactured.

The FDA UDI record does not identify EC89455 as required to carry a natural-rubber-latex warning, but it also does not identify the electrode as “not made with natural rubber latex.” Balego should therefore avoid an unqualified “latex-free” claim unless that exact wording appears on the current package.

Customers with a known latex allergy should verify the current product label before use.

Use Model 699 only with a compatible electrotherapy device and according to the device manual, electrode labeling, and a healthcare professional’s instructions.

Do not apply stimulation:

• Across the chest
• Through the head
• Over the eyes
• On the front or sides of the neck
• Over broken, infected, inflamed, or significantly irritated skin
• Over an area with severely impaired sensation
• In another location prohibited by the electrotherapy device manual

Do not use electrotherapy with a pacemaker, implanted defibrillator, or another implanted electronic device unless specifically cleared by the relevant medical specialist and device manufacturer.

Stop the session for:

• Burning
• Sharp or painful stimulation
• Persistent skin irritation
• Blistering
• Worsening symptoms
• Unexpected muscle movement
• Intermittent output caused by a damaged pad or lead wire

Richmar’s electrode instructions emphasize using self-adhesive electrodes according to the stimulator instructions and applying them only to sites selected by the healthcare professional.

Choose Uni-Patch Softy Model 699 EC89455 electrodes when the treatment setup requires the following:

• The exact Model 699 electrode
• A compact 1.75-inch square pad
• A side-pin connection
• Soft-foam construction
• Reinforced conductive solid gel
• A self-adhering reusable electrode
• A bulk package of 40
• Compatibility with a clinician-directed TENS, NMES, EMS, or FES system

Confirm the connector before ordering. EC89455 is not interchangeable with snap, tab, or standard pigtail electrodes merely because the pads have a similar size.
