The Shuangwei Biotechnology PRP Fully Automated Preparation System (30‑specification) consists of a single‑use platelet‑rich plasma preparation kit and a medical centrifuge.

Product Features 
“One centrifugation, one closed workstation, one-click preparation” 
Fully automated: The preparation and extraction processes are fully automated. 
Fully enclosed and pollution-free: The separation and extraction processes are conducted in a fully enclosed, pollution-free environment. 
Convenient operation: A single centrifugation step is sufficient to achieve the desired concentration, and the entire preparation process takes only 15 minutes. 
Precise concentration: By selecting the appropriate mode, the concentration can be precisely adjusted within a range of 2 to 8 times. 

Preparation Procedure (PRP30 Specification) 
1. Power on the equipment, and after the automatic reset is complete, open the top cover, inspect the interior cavity to ensure there are no foreign objects, and verify that the current equipment operation screen displays “START.” 
2. Close the device’s top cover. Note: When “OPEN” appears in orange on the display, it indicates that the top cover is closed. 
3. Verify the model and specifications of consumables, and inspect the integrity of the packaging. Do not use if the packaging is damaged. 
4. Open the package and remove the syringe, the preparation device, and other components. Note: Be sure to remove the base from the PRP preparation device before use. 
5. Use a syringe to draw 3 mL of anticoagulant. Note: The required anticoagulant is ACD‑A.

6. Collect venous blood at a ratio of 9:1 (blood to anticoagulant), drawing 15 mL into the syringe.

7. Inject the blood into the preparation device (at a 45-degree angle) through the upper inlet. Use another preparation device and syringe to inject an appropriate volume of saline solution (or an equivalent counterweight) for weight balancing. Note: The total volume of whole blood injected must be carefully controlled, and the blood should be introduced into the preparation device as slowly as possible.

8. Perform weight balancing. Note: The allowable deviation in the balancing weight is ±1 g.

9. Open the centrifuge lid, insert the blood‑containing preparation device into the blue sleeve, and place the balancing material into the other sleeve.

10. Remove the aspiration assembly and install it in the designated position on the device. Note: Before installation, be sure to check that the catheter and syringe connector are securely tightened; manually pull the syringe to verify there are no air leaks, and ensure the device has completed its reset procedure. During installation, leave a small length of catheter inside the chamber (within the blue circle)—do not allow it to be excessively long—and confirm that the syringe is properly seated in its corresponding holder slot.

11. Close the top cover, select the mode, and enter the centrifugation parameters; then click “START” to begin operation. Note: In standard mode, the centrifugation parameters cannot be set, whereas in custom mode, they can be configured.

12. After the device has finished operating, the display will show “END” and emit a beep. After tapping “END,” open the top cover and remove the syringe containing PRP. Note: Be sure not to tap “RESET” after selecting “END.”

13. Remove any other consumables from the chamber, close the top cover, and press “RESET” to reset the device. When the device’s operation screen displays “START,” the reset is complete. The entire procedure is now finished; if you wish to continue, return to Step 1.

[Contraindications]

1. Patients with bleeding disorders such as hemophilia, thrombocytopenia, sepsis, and leukemia are contraindicated for use.

2. Individuals with coagulation disorders or a history of hematologic diseases;

3. Patients with a history of anticoagulant therapy;

4. Severe hypoproteinemia;

5. Patients with severe shock that has not been corrected or who have other serious, life‑threatening injuries.
