Frequently Asked Questions - BlueTouch PR3743 PHILIPS

How to position the electrodes on the body?

Place the electrodes on the painful area, keeping at least 2 cm apart. Consult the diagrams in the manual for recommended positions based on pain type. Never place electrodes on an open wound or near the heart.

What is the maximum session duration?

Recommended sessions last 20 to 60 minutes. The device can be used up to 3 times a day. A built-in timer allows you to set the duration (15, 30, 45, or 60 minutes) or continuous mode.

Can I use the device while sleeping?

It is not recommended to use the device while sleeping, as you may not react to discomfort or irritation. Also, the device automatically turns off after 30 minutes of inactivity.

Are the electrodes reusable?

Yes, the adhesive electrodes can be reused about 30 times if cleaned with lukewarm water after each use and stored on the protective film. Replace them when adhesion decreases.

How to clean the device and electrodes?

Wipe the device with a dry, lint-free cloth. For electrodes, clean them with a damp cloth (lukewarm water) and let them air dry before placing them back on the protective film. Do not use chemicals.

What to do if the skin becomes red or irritated?

Stop using immediately and remove the electrodes. Irritation may be due to excessive adhesion or skin sensitivity. Use hypoallergenic electrodes and ensure the skin is clean and dry before application.

Does the device work without batteries?

No, the device requires 2 AAA batteries (1.5 V) included. When the low battery indicator lights up, replace the batteries quickly to ensure constant intensity.

Read this user manual carefully before you use the BlueTouch Pain Relief Patch and save it for future reference. This medical device is available without prescription. To achieve the optimal treatment success, we recommend that you use the device according to the treatment schedule and the instructions in this user manual. If you need further information or have questions, please visit

Intended use

The BlueTouch Pain Relief Patch is a wearable medical device intended for use on and by persons older than 18. It treats muscular back pain by supplying light and warmth to the body by means of optical power and thermal conduction. Its special blue LED light relaxes and helps to heal damaged muscles through improved blood circulation. The intended treatment area of the device is the upper and lower back. You can position the device on the treatment area with a strap and use it during your normal daily activities. The power for the device comes from non-exchangeable rechargeable batteries.

Contra-indications, reactions and side effects

Contra-indications

General health conditions

Do not use the device if any of the following general health conditions apply to you:

• pregnancy or breastfeeding
• fever
• uncontrolled high blood pressure or a cardiovascular condition (stroke, myocardial infarction, angina pectoris, arteriosclerotic vascular disease (ASVD), peripheral vascular disease, or (severe) congestive heart failure)
• severe or uncontrolled diabetes or diabetes with peripheral damage

• presence of an implanted medical device (screw, etc.) in or near the treatment area or presence of an active implantable medical device, such as a cardiac pacemaker, defibrillator, neurostimulator, cochlear implant, or an active drug administration device, anywhere in the body

• widespread pain

• poor general health
• schizophrenia, borderline syndrome or severe depression
• severe osteoporosis (T score of 2.5 and a history of 1 or more bone fractures) or another serious bone disease

Pain-related health problems

Do not use the device if any of the following pain-related health problems apply to you:

• unsuccessful back surgery or surgery to torso, head or back within the previous 8 weeks
• acute dislocation or fracture within the previous 8 weeks
• a degenerative central nervous system disease such as multiple sclerosis or Parkinson's disease
• spinal stenosis that causes back pain
• cauda equina syndrome or other neurological symptoms that indicate neuropathy
• sensory deprivation or diagnosed shingles or postherpetic neuralgia, especially in the mid-trunk area.
• an inflammatory disease or a chronic disease or an infection known to cause pain, such as spondyloarthropathy, rheumatoid arthritis, lupus erythematodes, Lyme borreliosis

Dermatological or oncological problems

Do not use the device if any of the following dermatological or oncological problems apply to you:

• a history of skin cancer or any other localised cancer or the presence of precancerous lesions or large moles in the treatment area
• sun allergy

• burnt or sunburnt skin

• if you take photosensitising medication, do not use the device if the package insert states that the medication can cause photo-allergic reactions, photo-toxic reactions or that you must avoid sun exposure

• if you are on steroids, as this medication makes the skin more susceptible to irritation
• a skin disease such as porphyria, polymorphic light eruption, chronic actinic dermatitis, actinic prurigo or solar urticaria that causes photosensitivity
• infections, eczema, unhealed tattoos, burns, inflammations (e.g. of hair follicles), lacerations, abrasions, herpes simplex, psoriasis, wounds or lesions and haematomas in the treatment area
• allergy to the surface materials of the BlueTouch Pain Relief Patch (polyurethane for the skin contact surface and polyester for the surface that does not touch the skin) or to the polyester of the straps

Reactions and side effects

• It is normal for the skin to become a little red during treatment. The cause of this skin redness is the increased blood circulation due to the warmth of the BlueTouch Pain Relief Patch. This skin redness is harmless and fades after the treatment has ended.
• You may sometimes notice tanning after treatment. The cause of this tan is the exposure to light - a similar effect to that caused by sunlight - or to warmth. This effect is harmless and fades away by itself after a number of weeks and sometimes a few months. Postpone treatment until the tan has disappeared. To prevent tanning, resume treatment in a lower mode and avoid excessive pressure on the BlueTouch Pain Relief Patch during treatment, for example by sitting or lying on it or by leaning heavily against it.

- Blue light may discolour tattoos in the treatment area.
