In medical and dental practices, the sterilization of medical instruments plays a central role in ensuring safe and infection-free treatment. Sealing devices are crucial for maintaining the sterility of medical instruments by sealing them airtight in special sterilization pouches. This protects the instruments from contamination by bacteria, viruses and other harmful microorganisms until their next use.
A sealing device typically uses heat to fuse the edges of the sterilization pouches and create a tight seal. The operation of the device is simple and only requires inserting the pouch into the device, setting the required temperature and pressure, and starting the sealing process. Modern sealing devices often offer adjustable parameters that allow the sealing conditions to be optimally adapted to the type of material and thickness of the bag.
To ensure consistent performance and reliability, modern sealing devices monitor the relevant process parameters and document them on a data carrier. In addition, tests such as the peel test and seal check should be carried out regularly to ensure that the seal complies with medical standards. Such tests help to identify and rectify any defects in the sealing process at an early stage.
The selection of the appropriate sealing device depends on several factors, including the type of instruments to be sealed, the quantity of pouches to be processed daily and the specific requirements of the practice. Various types of sealers are used in medical facilities, particularly bar sealers and rotary sealers, which differ in their operation and application.
Bar sealers, also known as impulse sealers, use a sealing bar with an integrated heating wire that heats up when switched on. They are ideal for practices with lower sealing requirements, as they produce each seal individually. These devices are easy to operate and require less energy due to the short heating phases.
In contrast, rotary sealers are designed for higher throughput rates. They have a conveyor belt that automatically transports the pouches to be sealed through the machine, making them an efficient and time-saving solution for facilities with high volumes of instruments to be sealed. Due to their continuous operation, rotary sealers are ideal for larger clinics or dental practices that require fast and continuous processing.
High-quality sealers offer adjustable temperature and pressure settings that allow customization to different materials and pouch sizes.
