The following is a detailed explanation of the usage details of the desktop sterilizer:

1、 Preparation before use

1. Environmental and equipment inspection: The workbench needs to be cleaned to ensure that there are no debris or dirt interfering with subsequent operations. At the same time, check whether the power cord, control panel, and indicator lights of the equipment are intact, and confirm that the sterilization agent has not expired and is prepared in proportion. In addition, it is necessary to drain the sewage and add distilled water to the designated water level.

2. Pre treatment and packaging of items: Items to be sterilized should be cleaned in advance, and instruments that have come into contact with pathogenic microorganisms should be treated with chemical disinfectants before cleaning. When packaging, materials with good breathability should be used for bundling and should not be too tight. The dressing package should be placed vertically to avoid contact with the inner wall of the sterilizer.

2、 Loading and parameter settings

1. Reasonable loading: Place items evenly on pallets to avoid overlapping stacking. Containers should be placed with their openings facing downwards or sideways to ensure steam penetration. Large items should be placed on the upper layer, and metal items should be placed on the lower layer to prevent condensation water from infiltrating the fabric.

2. Parameter setting and air conditioning removal: Select the sterilization program based on the type of item, and set parameters such as temperature, time, and pressure. Before sterilization, it is necessary to fully eliminate cold air, otherwise the temperature inside the pot cannot reach the expected value, which will affect the sterilization effect.

3、 Sterilization process monitoring

1. Real time monitoring and adjustment: Observe the sterilization process through a display screen or indicator light to ensure that the pressure steadily rises to the required value. If high-pressure steam sterilization is used, attention should be paid to avoiding the generation of superheated steam, as it cannot release latent heat and affect the effectiveness.

2. Time control: The sterilization time should be calculated from reaching the set temperature, including thermal penetration time and maintenance time, and the specific duration should be adjusted according to the properties of the item.

4、 Post sterilization treatment

1. Cooling and retrieval: After sterilization is completed, wait for the equipment to cool naturally and reduce pressure. After the pressure gauge returns to zero, slowly open the exhaust valve to retrieve the items. Wear sterile gloves when retrieving items to avoid touching and contaminating sterilized items.

2. Drying and Storage: Check if the item is dry and wipe it with sterile tissue if necessary. Sterilized items should be classified and stored at a certain distance from the ground to reduce the risk of secondary contamination.

5、 Maintenance and Precautions

1. Daily maintenance: After daily use, turn off the power, drain the sewage, and clean the inside of the equipment. Regularly check the safety valve and pressure gauge to ensure that the equipment is functioning properly.

2. Effect verification: The sterilization effect can be detected through chemical indicator cards or biological indicators, such as sulfur powder or benzoic acid melting tests.

The correct use of desktop sterilizers requires strict adherence to pre-treatment, loading, parameter setting, sterilization, and post-treatment processes, while also emphasizing equipment maintenance and effectiveness verification. Special attention should be paid to the removal of air conditioning, pressure control, and placement of items during operation to ensure sterilization effectiveness and safety.
