Malfunction of the hand pendant controlling movement of the therapy couch and nozzle may result in unintentional motion. Patient injury is possible if they come in contact with the nozzle or other objects in the treatment room.
Dimension Vista Magnesium Flex reagent cartridge lots exhibiting imprecision and intermittent Abnormal Assay flags. When this issue occurs, there is a potential for QC failures or erroneous patient results which may lead to repeat and follow-up testing.
The Hanger-Bar is being recalled due to the potential for the set screw loosening as a result of a manufacturing issue (failure to apply Loctite adhesive). As a result of the set screw loosening, there is the potential for a fall hazard.
An issue where the combined density in a dose grid voxel partially covered by the External ROI and also partially covered by an ROI of type Bolus, Support or Fixation may be unexpected.The density in the voxel can be both under- and overestimated
If the dynamic jaw mode is used and an optimization is continued after changing the dose grid or modifying the target ROI, the positions of the jaws may change unexpectedly for some control points. User must be aware to avoid unnecessary jaw openings during treatment planning
Siemens Healthineers has identified a software error in previous software version VB10 for the Ysio fully automated system. The unit may process incorrect internal values for the position of its ceiling tube stand. If the user activates a longitudinal or transversal movement at the time of the error, the system controls may initiate a correction of the tube stand position, resulting in an unintended movement. If the described error occurs, a potential for collision risk for objects or persons in the vicinity of the moving stand exists. This may result in minor to serious injuries to persons.
There is a potential that the DNA sequence analyzer may short circuit shortly after disconnection and reconnection of circuit board or imaging module due to an insufficient reconnection of the ribbon cable. The short circuit results in the device being inoperable.
New or replacement insulin pumps are not pre-programmed with basal rates or other verified settings (bolus wizard settings, sensor settings, etc.), which must be set up and saved on pumps prior to use. Patients who do not realize this will receive no basal insulin, which can lead to insulin under-delivery. Insulin under-delivery can cause severe hyperglycemia, which may lead to diabetic ketoacidosis. Current device labeling does not clearly identify that these insulin pumps are capable of functioning with the default basal setting of 0.0 units/hr for all 24 hours and that no error message will appear if the default basal setting remains active. Furthermore, the labeling for the affected devices does not highlight that saving the basal settings requires multiple steps and failure to complete all steps will not save the new basal settings, nor that the steps required to set and save a basal profile and other parameters which are used as part of the bolus calculator function are different.
The alarms can fail to alert consumers to the presence of a hazardous level of carbon monoxide, posing a risk of carbon monoxide poisoning or death. Carbon monoxide (CO) is an odorless, colorless, poisonous gas.
