Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a movable SPECT / CT bedside auxiliary injection device. Background Art

[0002] Many examination items on the large-scale nuclear medicine instrument SPECT / CT require bedside bolus injection to collect the blood perfusion phase. The blood perfusion phase will directly affect the patient's examination results, so the success of the injection is critical; however, the bed of the large-scale SPECT / CT instrument is 0.5 meters wide. After the patient lies down, the hand that needs to be injected can only be suspended in the air, which will seriously affect the success rate of the injection. Nuclear medicine examinations use isotope drugs. Once the injection fails, the patient cannot be examined again on the same day. Therefore, a movable SPECT / CT bedside auxiliary injection simple bracket is needed to fix the patient's injection site and increase the success rate of the injection. Utility Model Content
