Key Features of HY-D03 Model
The HY-D03 computer intermediate frequency drug iontophoresis therapy apparatus is a dual-output model capable of treating two patients simultaneously. Prescription, time, and dosage can be independently adjusted without mutual interference. This device can perform intermediate frequency physical therapy as well as targeted drug iontophoresis therapy. It features an adjustable heating function for thermal therapy and includes interferential current therapy capabilities, utilizing endogenous currents generated by differential frequencies. With dual-channel and dual-prescription settings, it can simultaneously treat the main affected area and symptom-induced zones. The wired remote control allows patients to autonomously adjust the output dosage, not only improving treatment efficacy but also reducing the workload of medical staff.
This instrument addresses the challenge of cell polarization electric fields during drug iontophoresis, enabling effective and sustained drug ion delivery. By creating an optimal medication environment, it targets pure drug ions (not compounds) directly to the lesion site, achieving higher local drug concentrations than oral or intramuscular administration methods. This results in prolonged pharmacological effects while avoiding the toxic side effects associated with other drug delivery routes.
The output of this device incorporates automatic巡檢 (inspection) and circuit break protection functions, ensuring that the required therapeutic dosage increases gradually rather than abruptly. This design fundamentally eliminates the risk of electric shock to patients, effectively safeguarding their personal safety.
Integrating intermediate and low-frequency physical therapy, drug iontophoresis, and thermal therapy into one unit, this instrument delivers comprehensive treatment efficacy, achieving multiplied therapeutic outcomes with half the effort. It is suitable for use in hospitals, clinics, and households at various levels.
