Software anomaly may incorrectly extend the on-analyzer stability time for a loaded VITROS Reagent.

Table may drift in the roll position while in use

Tosoh Bioscience has become aware of potential degradation of HbA1c control lot # 7055 before the 60-days product stability claim. If degradation of these controls occurs, P00 peaks may be seen and the % HbA1c control values may drift higher than the assigned range. This may result in delays when performing routine instrument quality control. If this issue occurs, there may be a delay in testing and reporting patient test results. Tosoh has received two (2) complaints related to this issue with no serious injuries reported.

Patient monitors may restart due to network overload caused by network configuration.

There is a potential for an undetected over temperature condition on the trans-esophageal (TEE) probe leading to a possible burn injury.

A problem has been detected in the Philips IntelliVue MX4O that, if it were to occur, could affect the performance of the equipment. The volume of the MX4O speaker in these devices may be diminished or not audible above 4,500 feet when operating in Monitor Mode. These devices may intermittently exhibit Speaker Malfunct INOP messages after the Power On Self-Test. The issue is only apparent when the device is being used in Monitor Mode at an altitude of greater than 4,500 feet.

Affected lithium-ion batteries may contain a defective component (Thermal Cut-off or TCO). Should the component fail, the battery will no longer charge or deliver power to the Monitor/Defibrillator, which may prevent operation of the device if it is not connected to AC or DC power. Should a second, unaffected battery be present in the Monitor/Defibrillator, the battery failure may go unnoticed.

The ventilator Inspiratory Safety Guard (ISG) may disconnect from the breathing circuit pathway. As a result, this could create a loss of ventilation which may lead to inadequate oxygenation for patients, increasing the possibility of hypoxia.

Due to a customer experiencing complaints on bone fraction of assay not being in range. The complaint: ~12% lower enzyme activity was noted.

Due to some cards in this lot reported to have experienced variations in results, (verified by wave form), resulting in some cards with shorter or longer times than expected.

If metal strips are removed and re-applied to another display, there is potential for the metal strips to be deformed resulting in a smaller contact surface with the front cover magnet strips. There is a risk that the protective front cover could come loose and may fall down.

The firm has detected a potential risk using the command. After releasing the command, the movement of the table may continue instead of stopping.

The firm has implemented new product labeling changes for the Tosoh AIA-360 Analyzer. These labeling changes affect the Tosoh Quick Reference Guide, Training Manual and Training DVD previously provided by Tosoh Bioscience. These changes are being made to align the Tosoh Quick Reference Guide and associated training materials to the Operators Manual and provide clarification to the requirement that the maintenance of the B/F probe is to be performed by Tosoh a field service representative, the requirement for use of 70% Ethanol during daily shutdown procedures and the requirement for use of CAP Class 1 reagent grade water for dilution of the concentrated wash and diluent solutions and reconstitution of lyophilized reagents. Failure to follow these requirements may negatively affect system performance, lead to corrosion of instrument components over time, or result in bacterial contamination, respectively.

This recall has been initiated due to a possible leakage of a hose in the cooling unit of the X-ray tube. The Artis zee system may lose coolant due to a possible leakage in a hose of the cooling unit in the X-ray tube. This will cause the X-ray tube not to be sufficiently cooled down. As a result, the system will display a message Tube hot, have a break . The X-ray will be blocked several minutes later and to prevent any damage to the machine the following message will be displayed NO XRAY, TUBE TOO HOT . This issue is very sporadic and may occur during an ongoing clinical procedure. Use of this product may have a potential impact on planned procedures as they may be delayed as well as in emergent cases, as clinical treatment may need to be terminated and transferred to a functioning system.

The patient monitors may simultaneously restart as designed if all are connected to the same network and a network overload occurs for a prolonged time.
