Medical chairs are essential auxiliary equipment in the diagnosis, treatment, and rehabilitation processes. Their proper use not only affects patient safety and comfort but also directly impacts the efficiency and quality of medical procedures. Given the special nature of their structure, function, and operating environment, several key points should be followed in daily operation to fully utilize their performance and extend their lifespan.
First, an inspection and preparation should be performed before use. Regardless of whether the chair is manually adjustable or electrically controlled, all components should be confirmed to be functioning normally before the patient is seated. Adjustment mechanisms should be free of jamming, locking devices should be reliable, and the seat, backrest, and armrests should be clean and free of contamination. For electrically operated medical chairs, the power connection and emergency stop function should also be verified to prevent sudden loss of control during operation. If disposable isolation covers or seat covers need to be replaced, ensure they fit properly and are securely fixed to prevent displacement that could affect hygiene or safety.
When the patient is seated, the chair posture should be adjusted according to the needs of the diagnosis or treatment. First, guide the patient to approach the chair with steady steps. A caregiver or medical staff should assist them in sitting down slowly to avoid instability caused by rapid movement. For chairs with armrests and footrests, adjust the armrests and footrests to a suitable height according to the patient's body size and condition to maintain functional joint positions and prevent the shoulders, elbows, or knees from being unsupported and subjected to pressure. For examinations requiring specific postures, such as dental or ophthalmological examinations, first position and lock the chair back, leg rest, and headrest before asking the patient to cooperate in securing them, to reduce errors and risks caused by changes in posture.
During operation, pay attention to dynamic safety. For medical chairs that can rotate or tilt, the adjustment process must be gradual and even to avoid sudden turns or steep tilts that could cause patient discomfort or falls. If the patient receives treatment on the chair for an extended period, check the contact points between the patient and the chair regularly to prevent pressure sores or redness caused by prolonged fixed posture, and adjust support points or add cushions as needed. For patients who are unconscious, have limited mobility, or are experiencing convulsions, restraints or assistive devices should be used, but the tightness must be appropriate to avoid affecting blood circulation and respiration.
Cleaning and disinfection must be maintained throughout the entire period of use. After each patient leaves the seat, visible dirt should be removed immediately, and the seat, armrests, footrests, and other contact surfaces should be wiped with an appropriate concentration of chlorine, iodine, or alcohol-based disinfectant according to medical infection control guidelines. For removable and washable fabric or mesh covers, they should be removed promptly for washing and high-temperature sterilization; for non-removable parts, special attention should be paid to seams and corners to prevent contaminant residue. The external surfaces of electric and pneumatic components also require regular cleaning to prevent liquid seepage into the drive structure and causing malfunctions.
Daily maintenance is equally important. A periodic inspection system should be established, focusing on the lubrication of the adjustment mechanism, the tightness of fasteners, and the integrity of the surface coating. Any wear, loosening, or malfunction must be reported and repaired or parts replaced immediately; operation with malfunctions is strictly prohibited. Chairs that are not used for extended periods should be stored in a dry, well-ventilated place to avoid moisture or direct sunlight, which can cause material aging.
In summary, these tips for using medical chairs cover pre-treatment checks, positioning adjustments, process safety, immediate cleaning, and regular maintenance. Adhering to a rigorous and meticulous approach, and upholding infection control and ergonomic principles, will ensure that medical chairs achieve maximum effectiveness in clinical practice and patient care, while simultaneously guaranteeing the safety and comfort of both medical staff and patients.
