What Are the Key Daily Maintenance and Care Points for Hydrogen Peroxide Low-Temperature Sterilization Equipment?

Daily Cleaning and Maintenance Requirements for the Sterilizer

1. Daily cleaning and maintenance of the sterilizer must be performed by trained CSSD personnel in accordance with the equipment's instruction manual.
2. The exterior of the sterilizer should be wiped down daily using a soft cloth dampened with water or a neutral detergent. When visible soiling is present on the inner chamber, the equipment power must be turned off first, then the chamber should be cleaned using a low-lint soft cloth with water or a neutral detergent, followed by thorough drying.
3. The sterilizer chamber must be kept clean at all times. Sterilizers that are not in use should remain powered on in standby mode, with the chamber door kept closed.
4. In accordance with the manufacturer's instructions, the hydrogen peroxide concentration monitoring probe and lens should be cleaned regularly using a low-lint wipe. Any visible contamination should be addressed immediately.
5. For sterilizers equipped with an evaporation tray, the integrity of the tray must be inspected. Any deformation or damage requires immediate replacement. As a general rule, the evaporation tray should be cleaned once per week.

Pre-Startup Safety and Basic Status Checks

1. Appearance and Power Supply: Inspect the unit body, power cord, and indicator lights for signs of damage or short circuits. Confirm the display screen is functioning normally with no active alarm codes.
2. Sterilization Chamber Inspection: Verify that the interior of the chamber, electrode mesh, shelves, and guide rails are clean, free of foreign objects, and dry. Ensure that metal instruments do not contact the chamber walls, door, or electrodes.
3. Door Seal Integrity: Clean the door gasket using a lint-free cloth. Check for cracks, aging, or crystalline deposits. Confirm the door opens and closes smoothly with a secure seal.
4. Consumables and Accessories: Confirm that the hydrogen peroxide cassette or liquid reservoir contains sufficient supply and is properly installed. Verify that printer paper and ink ribbon are adequate and that the printing device operates normally.
5. Vacuum Pump Status: Check the oil level and oil clarity of the pump. The oil should be clear with no signs of spraying, emulsification, or particulate contamination. Confirm the exhaust filter is in proper working condition.
6. Environmental Check: Ensure the equipment room is dry and well-ventilated, with an ambient temperature between 10°C and 30°C, and free of dust and corrosive gases.

Observations During Operation

1. Continuously monitor chamber pressure, temperature, plasma power output, and sterilization cycle time. All parameters must remain within the manufacturer's specified ranges, and complete records must be maintained throughout the entire cycle.
2. Observe the door seal and vacuum pump for abnormal sounds or vibrations. Any signs of unusual noise, air leakage, or triggered alarms should be investigated immediately.
3. Verify all physical monitoring data to confirm the cycle has not been interrupted and that no abnormal program terminations have occurred.

Post-Shutdown Cleaning and Records

1. Deep Cleaning of the Chamber: Wipe down the chamber walls, electrodes, shelves, and sensor probes. Remove any hydrogen peroxide crystalline residue, moisture, and soiling. Do not use abrasive cloths or rough materials.
2. Door Cleaning: Re-wipe the gasket groove and door contact surface. Allow the area to air dry before closing the chamber door.
3. External Cleaning: Wipe the outer housing and control panel to ensure no dust or surface contamination remains.
4. Consumable Reset: Empty the cassette collection bin, check remaining consumable levels, and prepare for the next day's operation.
5. Record-Keeping and Filing: Complete the daily maintenance log, including equipment serial number, inspection items, any faults encountered, maintenance personnel, and date. All records must be traceable.
