Automated: To complete the high-level disinfection of a point of use cleaned, enzymatically cleaned, and properly dried TEE Ultrasound Probe can be accomplished with the TD 100® Automated TEE Probe Disinfector. The TD 100 is designed to automatically high-level disinfect a transesophagael (TEE) echocardiogram ultrasound probe and thoroughly rinse disinfectant residue in less than 17 minutes. The TEE probe is placed into the disinfection reservoir of the TD 100 and simple and direct prompts allow the end user to set up and initiate the TD 100 to HLD and rinse the TEE probe. The TD 5 is a single use, FDA cleared high-level disinfectant that does not require individual MRC testing prior to use like other reusable solutions. At the conclusion, a printed receipt is furnished that documents the contact time, contact temperature of the disinfectant and indicates probe and operator ID of the disinfection cycle. The receipt then can be placed into the HLD TRACKER for later reference or audit.
Manual: Fill a high-level disinfectant basin with an approved chemical per the probe manufacturer’s guidelines and ensure proper ventilation as per the SDS that accompanies the chemical. Place the TEE ultrasound probe into the solution. Caution, when placing the probe into the solution should be maintained to prevent the handle and steering mechanism from being submersed thus resulting in liquid intrusion. This will result in probe damage and ultimately device inoperability. Only place the long insertion tube into the high-level disinfectant basin.
It is extremely important to review the high-level disinfectant instruction for use to determine soak time and contact temperature. Different disinfectants have different indications for use relative to the contact temperature. For example, an aldehyde based disinfectant might perform high-level disinfection in 45 minutes at 20 or 25 degrees C while at elevated temperatures the disinfection time might be as little as 5-12 minutes. Critical to the process is understanding the chemistry used and to make sure you follow the indications for use exactly. One of the weak points in manual reprocessing is the variations between high-level disinfectants and the ability to confidently ensure correct temperature of the disinfectant throughout the required contact time.
Precautions should be taken as occupation exposure to the high-level disinfect is a concern, as well as probe handling and soak time, when manually reprocessing a TEE ultrasound probe.
