Personal Laser L400 soft laser device

DETAILS

The Personal Laser L400 is a state-of-the-art, medically certified medical device that works on the principles of low-intensity laser therapy (LLLT) and photobiomodulation (PBM). The device uses 808 nm infrared laser light with a power of 400 mW, which effectively relieves pain and accelerates tissue regeneration.

Areas of application

The Personal Laser L400 is widely used to treat a variety of musculoskeletal problems and painful conditions.

Common applications of the soft laser are, but not limited to:

• Musculoskeletal problems: arthritis, tendonitis, bursitis, muscle strains and joint pain.
• Skin problems: acne, ulcers, scars and stretch marks.
• Ear, nose and throat problems: tinnitus and ear canal inflammation.
• Dental problems: inflammation of the jaw, facial nerve pain, facial nerve paralysis and gingivitis.

The benefits of laser light are scientifically proven. During treatment, the light energy entering the tissues stimulates cellular function, improves blood circulation and reduces inflammation. Regular use not only provides symptomatic treatment but also promotes the actual healing process.

It is excellent for the most common musculoskeletal complaints such as chronic back pain, neck pain and arthritis. It helps in the treatment of knee joint wear, shoulder girdle problems and jaw joint inflammation. It is also excellent for promoting wound healing (e.g. scars, ulcers, stretch marks, acne) and rehabilitation after surgery.

Easy and safe to use

The Personal Laser L400 is designed to be extremely user-friendly. It is compact, measuring just 76 mm long and 27 mm in diameter, and weighs only 42 grams. Thanks to its ergonomic design, it is easy to use and can be precisely positioned in the area to be treated.

Several built-in protections guarantee safe use. The device switches off automatically after 5 minutes of use or if it overheats. The built-in LED display keeps you constantly informed of the operating status. The green light indicates active treatment, yellow indicates standby and red indicates a possible fault.

The device is powered by a rechargeable Li-Ion battery, which, when fully charged, lasts for 2 hours of continuous use. Charging is done via a simple USB connection and takes just 1.5 hours to fully charge. The battery charge level is also indicated by an LED display.

Treatment protocol and dosing

For effective treatment, it is important to follow the correct protocol. For chronic problems, one treatment per day is recommended for the first week, which can be reduced to 2-3 times per week in the second to third week, and then to 1-2 times per week from the fourth week onwards.

For a single treatment point, a treatment time of 3-4 beeps (30-40 seconds) is usually recommended, delivering 12-16 joules of energy to the tissues. The device emits a beep every 10 seconds to indicate when to change position. This helps avoid excessive local heating and ensures optimal energy delivery.

Different areas require different treatment times:

• Wounds and skin surfaces: 2-5 joules/cm²
• Tendons, joints, muscles: 5-10 joules/cm²
• Pain points: 10-150 joules or until pain is relieved

During treatment, the device must be placed directly on the skin surface. However, in case of an open wound, keep the device at a distance of about 5 cm. When treating larger areas, proceed point by point, treating each point for the recommended time.

Quality and guarantee

The Personal Laser L400 is manufactured in accordance with the strict EU standards for medical devices. It is CE certified (CE 2274) and complies with the requirements of the ISO 13485:2016 quality management system.

It is covered by a 3-year warranty. The laser diode is designed for 10,000 hours of operation, which ensures several years of trouble-free operation under average use.

Safety information and precautions

Although the device is designed for home use, it is important to follow some basic safety precautions. Never point the laser light in or around the eye. Do not use in the abdominal area if pregnant. Treatment of tumour areas is also contraindicated.

Consult a doctor or health care professional before using the device. This is particularly important in cases of epilepsy, blood clotting disorders or other chronic diseases. Always follow the recommended protocol and do not exceed the recommended treatment times.

Scientific background and effectiveness

The therapeutic use of laser light has a long history going back several decades. Numerous clinical studies have demonstrated its effectiveness in treating various musculoskeletal problems. The 808 nm wavelength is particularly suitable for deeper tissues because of its optimal penetration depth.

The 400 mW power delivered by the Personal Laser L400 is an ideal compromise between efficiency and safety. This is sufficient energy to produce a therapeutic effect, while at the same time not causing undesirable side effects when used correctly.

Maintenance and hygiene

The device requires minimal maintenance. Clean the laser optics after each use with a 70% alcohol solution. Make sure that the power is switched off when cleaning the lens. The housing can be wiped with a slightly damp cloth or disinfectant wipe.

For hygienic use, the handpiece should be disinfected after each patient. The use of a transparent foil, which prevents direct contact with the skin surface, can be a practical solution.

Compare

The Personal Laser L400 offers several advantages over the Safelaser 500 or B-Cure:

Higher laser class: the Personal Laser L400 is a class 3 laser, which means higher power and efficiency compared to class 1 devices such as the B-Cure or Safelaser 500. Although class 3 lasers require protective goggles, the increased power allows for faster and more efficient treatment.

Higher power and shorter treatment time: the Personal Laser L400 emits a continuous laser beam of 400 mW. The Safelaser 500 and B-Cure use prisms and are therefore lower power.
The higher power means that the L400 delivers the required amount of energy to the tissue faster. In addition to significantly shorter treatment times, treatment efficiency is also higher.
For example, it takes only 12.5 seconds to deliver 5 joules of energy with the Personal Laser L400, compared to 5-8 minutes with the B-Cure and 2-3 minutes with the Safelaser 500.

Deeper tissue penetration. This allows, for example, more effective treatment of larger joints, cartilage and ligaments.

More precise treatment: the L400 laser beam has an area of 1 cm², which is smaller than the B-Cure (4.5 cm²) or Safelaser 150 (2.5 cm²). This smaller beam diameter allows for more targeted treatment, especially in smaller areas or specific points such as trigger points, nerve injuries or polyneuropathy.

Overall, the Personal Laser L400 (compared to the other two devices) can provide more effective and faster treatment, especially for deeper tissue problems.
