Varying instrument surface properties make it essential to select brushes whose bristles match the cleaning specifications of the instruments in question. The relative brush abrasion should be calibrated to ensure that the removal of the various kinds of soiling does not damage your highly valuable instruments. At the same time, however, the brush should also not be too soft, as this will prevent it from effectively removing contaminants.

In order to meet these challenges, Interlock Medizintechnik offers you four high-quality brushes in different grades of stiffness. Thanks to their specially designed bristles, all of the brushes are capable of removing the most stubborn of residues, including coagulated blood. With a thermal resistance of up to 134 °C, the brushes can be cleaned using standard disinfecting equipment. The brushes’ ergonomically shaped handle is suitable for both right and lefthanders.

LDPE Security Bags

To minimize the risk of recontaminating disinfected medical devices, as per the KRINKO/BfArM recommendation*, Interlock Medizintechnik LDPE offers LDPE security bags in six different sizes. The bags are transparent, so their contents can easily be identified without needing to open the packaging. Documentation fields on the outside of the bags and on the tear-off receipts allow for process transparency for all users as well as for implementing into your documentation. All bags have a serial number, which may be used for tracing medical devices. A 40 mm security closure helps to protect the user as well as the patient. It is immediately apparent, if the bag has been reopened after sealing.

Please always adhere to predefined maximum storage periods for disinfected products when using Interlock safety bags!

*Recommendation from the Commission on Hospital Hygiene and Infection Protection at the Robert Koch Institute (RKI) and the Federal Institute for Drugs and Medical Devices (BfArM) on the „Hygiene requirements for the reprocessing of medical devices“, 2012. 2.2.2 Drying; 2.2.4 Packaging; Annex 8 section: 3.7

With their various lengths, diameters and shapes, the Interlock brush sets are suitable both for hollow and standard instruments. Many of the brushes are heat-resistant and can therefore be cleaned and disinfected in the WD. All brushes are available as separate items as well.

In addition to an endoscope brush set, for example with special brushes for biopsy valves, Interlock also offers sets of MIS brushes with ring handles for optimal storage organisation and better handling in the cleaning process. The portfolio is completed by mixed brush sets consisting of various MIS brushes and cleaning brushes.

Cable Binders

Thanks to their convincing quality, variety of available versions and diversity of applications, Interlock’s cable binders are already being used in virtually every CSSD today. Silicone or plastic versions allow universal application.

The Interlock cable binders optimise both the packaging process in the CSSD / SPD and the withdrawal of the instruments in the operating theatre, by ensuring quick and easy identification of instruments, sets and trays. They also are ideal for attaching tray signs to trays. Labelling of instruments for repair or replacement is likewise easily possible with the Interlock cable binders.

The high tensile strength and the special closure variant make the plastic cable binders an ideal product for tamper-proof sealing of trolleys, whereas silicone cable binders optimally protect the instruments during bundling in the tray. All Interlock cable binders are heat-resistant and can thus be sterilized at 134 °C.
