Intended Use
The Ortho Dx, a non-invasive electrical stimulator that combines symmetrical biphasic neuromuscular stimulation with high volt pulsed direct current neuromuscular stimulation to be used under medical supervision for adjunctive therapy in the treatment of medical diseases and conditions. It is used to, relax muscle spasm, prevent or retard disuse atrophy, increase local blood circulation, reeducate muscles, prevent venous thrombosis with immediate post surgical stimulation in calf muscles, and increase range of motion.
Device Description
The Ortho De is a non-invasive electrical stimulator that combines symmetrical biphasic neuromuscular stimulation with high volt pulsed direct current neuromuscular stimulation that will operate in both modes simultaneously or independently. This system is a prescription device intended for use on patients who are undergoing rehabilitation for medical diseases and conditions on the order of a licensed practitioner.
More Information

Not Found

No
The summary describes a standard electrical stimulator and does not mention any AI or ML capabilities.

Yes
The device is described as an "adjunctive therapy in the treatment of medical diseases and conditions" with specific therapeutic uses such as "relax muscle spasm," "increase local blood circulation," and "prevent venous thrombosis."

No

The device description clearly states its purpose as a non-invasive electrical stimulator for adjunctive therapy in the treatment of various medical conditions, focusing on stimulating muscles and improving circulation. It does not mention any diagnostic capabilities or the ability to identify diseases or conditions.

No

The device description explicitly states it is a "non-invasive electrical stimulator" and describes its operational modes and parameters, indicating it is a physical hardware device that delivers electrical stimulation.

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

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • Device Description and Intended Use: The Ortho Dx is described as a non-invasive electrical stimulator used for adjunctive therapy in the treatment of medical diseases and conditions. It applies electrical stimulation to the body (specifically mentioned are calf muscles) to achieve therapeutic effects like muscle relaxation, preventing atrophy, increasing blood circulation, etc.
  • No Mention of Samples: There is no indication that this device analyzes any samples taken from the body. Its function is to deliver electrical stimulation to the body itself.

Therefore, the Ortho Dx falls under the category of a therapeutic medical device, not an in vitro diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

The output wave form, amplitude, pulse width, pulse rate, treatment time, NMS off time, NMS ramp up time and NMS ramp down time have been verified to the technical requirements listed in the operators manual. All measurements were taken at room temperature (72°C) with a relative humidity of 50% using a calibrated 5V power supply with a maximum capacity of 3 ampere continuous current and calibrated measurement equipment. These values are within and/or identical to the operating parameters of the predicate devices. The Ortho Dx neuromuscular stimulator uses the same power supply and proposes no additional safety considerations than the legally marketed predicate devices (NM II/III and GV II). The Line Powered Repac10 employees a UL approved power supply and is legally marketed with the predicate devices (NM II/II and GV II).
