NORM TRAY. COUVERCLE. NON-PERFORE. - Helmut Zepf

What is the Norm Tray - Non-Perforated Lid - Helmut Zepf?

The Norm Tray (reference 85.142.20) is an instrumentation management accessory designed by Helmut Zepf. It is a non-perforated lid intended to cover surgery trays or cassettes. Manufactured from medical stainless steel, this component allows the dental examination tray to be hermetically closed from the top, providing physical protection for manual instruments. Its solid structure, without perforations, is specifically designed for protocols where strict separation from the external environment is required before or after treatment phases, thus ensuring rigorous organization of the technical platform in dental or implant surgery practices.

What are the clinical indications?

This instrumentation cassette lid is indicated for the protection and management of manual instruments during oral surgery, implantology, and periodontology procedures. It is used to cover the dental norm tray to maintain the integrity of instrument sets during transport between the decontamination area and the chair, or during post-sterilization storage. As part of the dental examination tray system, it facilitates the maintenance of an orderly and secure working environment, limiting the risk of drops or accidental contact with sharp or pointed instruments before their clinical use by the practitioner.

What are the technical characteristics?

The Helmut Zepf lid, bearing technical reference 85.142.20, is distinguished by its non-perforated design. Unlike filtering models, this solid version ensures total coverage of the surgery cassette. It is designed in high-quality medical stainless steel, a material chosen for its resistance to repeated cleaning and disinfection cycles. This device belongs to Class I according to medical device regulations. It is delivered non-sterile and must undergo a complete cycle of cleaning, disinfection, and sterilization before its first use and between each patient, in accordance with current hospital hygiene protocols.

What are the contraindications for use?

The main contraindication related to the use of this medical stainless steel device is known hypersensitivity or intolerance to metals in the patient. Although the lid is not an invasive instrument, any direct or indirect contact can trigger an allergic reaction in sensitive subjects. The manufacturer Helmut Zepf specifies that if such a hypersensitivity reaction occurs during the procedure, it must be immediately interrupted and necessary medical measures must be taken. Furthermore, it is strictly contraindicated to use the product if it shows visible damage such as cracks, breaks, or structural deformations compromising its protective function.

What are the maintenance and reprocessing precautions?

Due to its stainless steel composition and robust design, there is no defined maximum limit of treatment cycles for this surgery cassette lid, as long as its physical integrity is preserved. Before each use, the practitioner must visually inspect the device to detect any trace of wear or corrosion. The reprocessing process must include thorough cleaning, disinfection, and sterilization. It is crucial to verify compatibility with other cleaning products and solutions used in the sterilization chain. The use of damaged products or those with defects on the edges is strictly prohibited to guarantee the aseptic safety of the tray.

Who is the manufacturer and what standards are respected?

This device is manufactured by Helmut Zepf Medizintechnik GmbH, a recognized manufacturer located in Seitingen-Oberflacht, Germany. The Norm Tray lid is classified as a Class I medical device (Class Ir according to certain reprocessing nomenclatures). It meets the regulatory requirements for manual dental instruments. The manufacturer mandates that these products be handled exclusively by qualified healthcare professionals. Helmut Zepf's traceability and manufacturing quality guarantee that this lid meets the standards necessary for intensive use in a surgical environment, subject to strict compliance with the cleaning and sterilization instructions set out in the manufacturer's technical manual.
