Jet Spray Dermal Handpiece With Spaced Touch Surface Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dermal treatment technologies face challenges in consistently and effectively delivering therapeutic agents to the skin due to variability in spray application distance and difficulty in maintaining a controlled proximity of nozzles to the skin during treatment.
Innovation Solution
A multi-technology dermal treatment unitary handpiece that integrates a jet spray delivery system with symbiotic treatment elements, such as electroporation or ultrasound, where the operative end member and dermal touch surface are laterally spaced and axially displaced from the nozzles, allowing for adjustable spray application distance and precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the nozzle is positioned closer to the skin to improve spray delivery effectiveness, then the therapeutic agent penetration improves, but the risk of harmful effects and loss of substance increases
Solution Approach 1:
The patent introduces a dermal touch surface as an intermediary element between the nozzle and the skin. This touch surface acts as a mediator that allows the nozzle to be positioned at an optimal distance from the skin while still achieving effective therapeutic agent delivery. The touch surface provides a safe interface that prevents direct contact between the nozzle and skin, thereby reducing the risk of harmful effects while maintaining treatment efficacy.
2Ease of operation
If the spray application distance is not controlled to maintain consistency, then the device is easier to operate, but the manufacturing precision and treatment reliability deteriorate
Solution Approach 1:
The patent implements a pre-configured axial displacement between the nozzle and the dermal touch surface, which is determined during device assembly. This preliminary positioning ensures that the spray application distance is consistently maintained at an optimal value throughout the treatment process. The fixed geometric relationship is established in advance, eliminating the need for real-time adjustment by the operator while ensuring precise and repeatable spray delivery.
3Adaptability or versatility
If multiple treatment technologies are integrated into a unitary handpiece, then the treatment efficacy and adaptability improve, but the device complexity increases
Solution Approach 1:
The patent combines multiple treatment technologies, specifically jet spray delivery and electroporation, into a single unitary handpiece. The jet spray system delivers therapeutic agents through a nozzle, while the electroporation element with dermal touch surface provides enhanced penetration. These distinct functional components are merged into one integrated device, allowing simultaneous or sequential application of both treatments, thereby improving overall treatment efficacy and versatility.
Solution Approach 2:
The unitary handpiece is designed to perform multiple functions: jet spray delivery of therapeutic agents and electroporation treatment. The device can deliver different types of treatments through its integrated components, making it a universal tool for various dermal therapy applications. This multi-functionality allows a single device to replace multiple separate treatment devices, improving adaptability across different treatment protocols.
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
Enhances the porosity of the epidermis, ensuring consistent and effective delivery of therapeutic agents by combining jet spray therapy with electroporation or ultrasound, improving penetration and treatment efficacy.
Implementation Method 1
a high-velocity liquid-gas jet spray formed of droplets of a therapeutic agent in liquid suspension
Implementation Method 2
The spray applied to the skin of a subject as a streaming mist
Implementation Method 3
Electroporation, for example, uses electrical pulses so as to increase cell permeability and to help deep penetration of skincare products
Implementation Method 4
Ultrasound therapy, known also as phonophoresis and sonophoresis, is well known for assisting with the administration of therapeutic agents transdermal

AI summary
A multi-technology dermal treatment unitary handpiece includes a jet spray delivery handpiece having an elongate housing terminating in one or more nozzles for directing along an axis a therapeutic spray towards the skin of a subject at a desired spray application distance therefrom; and one or more symbiotic treatment handpiece elements terminating in an operative end member having a dermal touch surface for conveying a treatment to the skin, the treatment being symbiotic with therapy provided by the therapeutic spray, wherein the operative end member and the touch surface are laterally spaced apart from the axis, and wherein the operative end member and the touch surface are axially displaced from the one or more nozzles by a distance determined to limit the proximity of the one or more nozzles to the skin of a subject to no less than the desired spray application distance.
