1. What is PRP? 
Platelet‑rich plasma (PRP), or concentrated platelet plasma, is prepared by centrifuging autologous whole blood to obtain a platelet‑rich fraction. Upon platelet activation, the α‑granules within PRP release a wealth of growth factors, yielding remarkable clinical benefits in wound healing while avoiding the risk of allogeneic immune rejection. By harnessing the body’s own physiological regulatory and reparative mechanisms, PRP accelerates tissue repair, alleviates pain, and modulates inflammation, making it a cornerstone of biological therapies. Owing to its efficacy, safety, long‑lasting effects, abundant availability, and broad therapeutic applications, PRP has been widely adopted across numerous disciplines of regenerative medicine.

2. Advantages of Platelet-Rich Plasma (PRP) Therapy 
① The fundamental solution: PRP therapy utilizes growth factors derived from the patient’s own blood to repair and regenerate damaged tissues, offering a treatment that addresses the root cause of the problem. 
② Short treatment time: The procedure takes only 10–20 minutes and allows for an immediate return to daily activities afterward. 
③ Short recovery time: Patients can resume their daily activities immediately after the procedure. Under normal circumstances, mild redness and swelling typically subside within 2–3 hours, and any traces of the treatment completely disappear within 2–3 days. 
④ Few adverse reactions: PRP therapy uses the patient’s own blood, and adverse reactions and side effects are rarely reported. 
⑤ Broad applicability: PRP can be used alone or in combination with a variety of existing procedures, enhancing treatment outcomes and thereby increasing postoperative satisfaction. 
⑥ Proven effects: The abundant growth factors contained in PRP can accelerate the natural regenerative capacity of aged tissues. Its reparative properties enable the treatment of injuries to cartilage, ligaments, and tendons. 
⑦ Convenience: Depending on the patient’s condition, 3–5 injections are recommended, with intervals of 2–3 weeks between each session. Therefore, this treatment is also suitable for patients who cannot visit the clinic frequently.

Shuangwei Biotechnology PRP Fully Automated Preparation System 
(15/30 specification) 
Sunway Biotech PRP Fully Automated Preparation System (15 specifications) Composed 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: The desired concentration can be obtained with a single centrifugation, 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 (PRP15 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 up the anticoagulant, collecting 1.5 mL. 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 blood injection volume must be carefully controlled, and the blood should be infused 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 click “RESET” to reset the device. The reset is complete when the device’s operation screen displays “START.” 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.
