PET Unit Dose Cabinet（PETUnit dose cabinet It is used in the field of nuclear medicine PETKey equipment for temporary storage and management of radioactive drugs before injection.PET Unit Dose Cabinet（PETUnit dose cabinetThe specific applications and workflow in nuclear medicine are as follows:

1 core purpose

In PETMedications (such as fluorodeoxyglucose)F-18 FDG）After the packaging is completed and before the patient injects, this device is used for safe and orderly temporary storage of pre packaged unit dose syringes, and provides radiation shielding and process management functions.

II Positioning in the workflow

1. After the packaging is completed: the pharmacist is presentPETDivide high activity drugs into multiple syringes in the hot chamber and cover them with lead protective covers.

2. Temporary storage and sorting: The packaged syringes should be arranged in the order of patient, examination time, or bed to avoid confusion or misplacement.

3. Pre injection temporary storage: Nurses take syringes from this cabinet in sequence and send them to the injection room for patient injection.

3、 Main functional features

4、 Areas with similar devices

5、 Application scenarios

·PET/CTdepartment: Used for F-18TheGa-68Temporary storage of dose before injection of positron emission drugs.

·Nuclear Medicine Pharmacy:As between the packaging hot chamber and the injection area Transfer safety station.

·Multi patient assembly line operation:Support the orderly scheduling of doses during consecutive examinations of multiple patients.

Summary:

PET Unit Dose CabinetEssentially, it is' packaged 'PETIntelligent temporary storage manager for syringes, which provides shielding protection+The dual design of process error prevention ensures the safety and traceability of radioactive drugs in the pre injection stage, which is an important equipment for modern nuclear medicine to improve work efficiency and safety standards.

In the standard process, the drug has been accurately dispensed and activity measured using the built-in activity meter in the dispensing chamber. So, why does a 'temporary storage cabinet' still need an activity meter?

The answer is:This is not a simple temporary storage cabinet, but an intelligent workstation that integrates "final quality control, dose verification, and information management" functions.

The activity meter equipped with it (usually a well type probe) mainly solves the problem ofAfter packaging and before injectionSeveral key quality control and process pain points:

The activity metercore purposeWhy do we need a second measurement

1. Final dose validation and error prevention (most critical)

²Purpose: To confirm whether the activity inside each syringe removed from the hot chamber is consistent with the prescription requirements in the pharmacy information system.

²Scenario: This is a physical level to prevent packaging errors and taking the wrong syringe. When the operator places the syringe into the designated position in the cabinet, the activity meter automatically measures and compares it with the system data. If there is any deviation, an alarm will be triggered.

2. Decay time calibration

²Purpose: To provide activity values before injection.

²Scenario: There may be intervals of several minutes to tens of minutes between the completion of packaging and actual injection. The activity meter inside the cabinet can measure the current actual activity immediately before injection, providing nurses with the most accurate and decay corrected values for recording and calculating the actual injection dose of patients.

3. Surface contamination inspection

²Purpose: To indirectly check whether there is radioactive contamination on the outer surface of the syringe.

²Scenario: If the outer surface of the syringe is contaminated and a well shaped probe is placed for measurement, it will cause an abnormal increase in readings. This can prompt the operator to perform decontamination treatment on the syringe to prevent contamination from spreading.

4. Automated recording and tracing

²Purpose: To generate complianceGMP/GDPStandardized and tamper proof dose distribution records.

²Scenario: Each measurement data can be automatically bound with patient information and timestamp, and uploaded to the management system, forming a complete and auditable dose distribution chain that meets strict regulatory requirements.

Summary: It is not only a "cabinet", but also an "intelligent terminal"

Therefore, equipped with an activity meter PET Unit Dose CabinetIt should be understood as:

“PETUnit dose final quality control and distribution station

The role it plays is:

Receive finished products from the hot chamber”→Conduct final quality inspection (activity verification) →Complete decay calibration before injection →Generate legal records → Safely and orderly distribute to nurses.

In short,For high standards and high trafficPETCenter, this is a way to enhance security, compliance, andworkflowThe key equipment for workflow automation is not just providing a shielded storage space. For users, you can explain it as follows: it is equivalent to a precision testing and packaging assembly line before the drug leaves the factory.
