Dual-Chamber Syringe for Layered PRP Delivery in Skin Rejuvenation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for applying platelet-rich plasma (PRP) in skin rejuvenation treatments are not optimized for efficiency, particularly in terms of PRP amount, application location, and diffusion through skin layers, and existing fractional laser treatments have longer recovery times and adverse reactions.
Innovation Solution
A dual chambered syringe system with controlled fluid communication between chambers allows precise separation and application of PRP layers, combined with various delivery systems for topical or injection methods, including brush, sponge, flexible brush, spiral, ballpoint head, micro-needles, and roller delivery systems, and integrated with fractional laser treatments to enhance treatment outcomes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ablative fractional laser treatment is used to create thermal injury channels for skin tightening, then skin rejuvenation outcomes are improved, but recovery time increases and adverse reactions occur
Solution Approach 1:
The patent applies PRP to the skin surface before fractional laser treatment to pre-condition the skin and promote faster healing. The growth factors in PRP are delivered in advance to the treatment area, preparing the skin for the upcoming thermal injury and reducing subsequent recovery time and adverse reactions.
2Ease of operation
If PRP is applied topically to the skin surface, then application simplicity is improved, but diffusion efficiency through skin layers decreases
Solution Approach 1:
The patent uses fractional laser treatment to create periodic micro-channels in the skin at controlled intervals. These periodically formed channels allow PRP to penetrate through the skin layers more efficiently when applied topically, combining simple application with enhanced diffusion through the periodic channel formation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system enables controlled and efficient application of PRP, reducing recovery time and adverse reactions, improving skin rejuvenation outcomes by optimizing PRP distribution and integration with fractional laser treatments.
Implementation Method 1
The ablative fractional laser treatment creates ablative microscopic channels of thermal injury that causes skin tightening and smoothening
Implementation Method 2
it also depends on the diffusion of the PRP through the skin layers

AI summary
A dual chambered syringe includes: an inner barrel defining a first inner chamber, the inner barrel having an apertured stopper at its distal end, the inner barrel being open at its proximal end; a shaft adapted to fit within the inner barrel, the shaft having a distal end which is engageable with the aperture of the stopper; a device for controlling engaging and disengaging of the distal end of the shaft with the aperture of the stopper; an outer barrel concentric with the inner barrel defining a second inner chamber, the outer barrel having a distal end for receiving and dispensing fluids and a proximal end into which the distal end of the inner barrel is insertable into the second inner chamber; the apertured stopper engages the second inner chamber of the outer barrel and selectively prevents or permits the passage of fluids between the outer barrel second chamber and the inner barrel first chamber; the inner barrel having an engageable surface on its outside surface; and, the outer barrel having operatively associated therewith an engaging device for selective engagement and disengagement with the engageable surface on the inner barrel.
