PRX Tubes
Single spin tubes for injectable I-PRF and A-PRF, with no chemical activator and no anticoagulant.
Applications
Skin rejuvenation.- Hair restoration.
- Joint injuries and osteoarthritis, at the knee, hip and shoulder, one of the uses D-MED names for the PRP therapy these tubes serve.
- Tendon injuries, one of the uses D-MED names for the PRP therapy these tubes serve.
- Chronic wounds, diabetic wounds and poorly healing tissue, one of the uses D-MED names for the PRP therapy these tubes serve.
How it works
The PRX Tube prepares injectable I-PRF with no chemical activator and no anticoagulant, and what makes that possible is the wall of the tube. D-MED smooths that inner wall with what it calls micro-polishing technology, and states the smooth surface prevents platelet aggregation, which is what lets I-PRF be obtained without an anticoagulant. A single centrifugation of three minutes separates the plasma, one tube gives 3 to 4 mL, and what comes out stays injectable for up to 30 minutes. For pure A-PRF, D-MED publishes a two-tube protocol: spin at 700G (2,400 RPM) for 3 minutes, transfer all the plasma into the second tube, spin again at 290G (1,500 RPM) for 14 minutes, and clean fibrin tissue comes out in 16 minutes, with no cutting and no mixing with the red cell layer. That is the mechanism of the tube. D-MED publishes no clinical indication and no mechanism of action for the tube itself: what it treats is what the PRP and I-PRF protocols it serves treat, and every use listed above is attributed to D-MED in the bullet that carries it.
Spin
Single cycle, 3 minutes
Yield
3 to 4 mL per tube
Usable window
Up to 30 minutes after the spin
Chemical activator
None
Anticoagulant
None
Pure A-PRF protocol
Two PRX tubes, double centrifugation, 16 minutes
Pure A-PRF, first spin
700G (2,400 RPM) for 3 minutes
Pure A-PRF, between spins
All the plasma goes into the second tube
Pure A-PRF, second spin
290G (1,500 RPM) for 14 minutes
Why this system
No chemical activator, no anticoagulant
PRX Tubes prepare injectable I-PRF and A-PRF without either.
One spin, three minutes
A single, three-minute spin separates the plasma fraction.
A 30-minute window
The prepared plasma is usable for up to 30 minutes after the spin.
3 to 4 mL yield
Each tube yields 3 to 4 mL of plasma.
What to know
Practice value
- Protocol: Injectable I-PRF and A-PRF, no chemical activator, no anticoagulant
- Spin: Single spin, 3 minutes
- Usable window: Up to 30 minutes
- Yield: 3 to 4 mL
Does PRX Tubes need a chemical activator?
No. It prepares injectable I-PRF and A-PRF without a chemical activator or anticoagulant.
How long is the prepared plasma usable?
Up to 30 minutes after a single, three-minute spin.
How much plasma does one tube yield?
3 to 4 mL.
How is pure A-PRF prepared with these tubes?
With two PRX tubes and a double centrifugation: 700G (2,400 RPM) for 3 minutes, all the plasma into the second tube, then 290G (1,500 RPM) for 14 minutes. D-MED puts the whole sequence at 16 minutes, with no cutting of the red cell layer.
Why does the inner wall matter?
D-MED micro-polishes it. It states the smooth surface prevents platelet aggregation, which is what lets I-PRF be obtained without an anticoagulant.
Does D-MED publish an indication for the tube itself?
No. D-MED publishes what the tube produces, PRP and I-PRF, and publishes the uses of that therapy separately. The uses listed under Applications are attributed to D-MED as uses of the therapy, never as indications of the tube.
