One-Handed Suction Device for Skin Foreign Substances
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foreign substance inhalers are difficult to operate with one hand and have limitations in accessing body parts due to their design, making it inconvenient to remove substances like insect stings and saliva from various skin areas.
Innovation Solution
A foreign substance inhaler with a suction body, a gripping tube that slides along the suction body's outer surface, and a piston body that generates negative pressure through up-and-down motion, allowing for easy one-handed operation and adjustable suction force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the conventional inhaler uses a handle that must be pulled upward with two fingers, then the suction function can be achieved, but the device cannot be operated with one hand and has limited accessibility to certain body parts
Solution Approach 1:
The device is divided into separate functional components: a suction body for creating negative pressure and a gripping tube for hand operation. The gripping tube can be held by the hand while the suction body contacts the skin, allowing independent optimization of each component's function and enabling one-handed operation on various body parts including difficult-to-reach areas.
Solution Approach 2:
The operating mechanism transitions from vertical pulling motion to horizontal pressing motion. The user presses the suction body against the skin while holding the gripping tube, changing the dimension of operation from upward pulling to lateral pressing, which enables access to body parts that were previously inaccessible.
2Reliability
If the handle must be continuously held and pulled during inhalation, then suction can be maintained, but the operation becomes troublesome and difficult
Solution Approach 1:
The suction body is designed to maintain suction automatically once activated. The pressing action creates negative pressure that continues to function without requiring continuous manual manipulation, allowing the device to serve itself by maintaining the vacuum state through its structural design rather than requiring ongoing user input.
Solution Approach 2:
The suction mechanism is activated by a preliminary pressing action that establishes the negative pressure state. Once this initial action is performed, the suction is maintained without requiring further manipulation, effectively performing the useful action in advance and eliminating the need for continuous operation.
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
Enables efficient and comfortable one-handed suction and removal of foreign substances from any body part, regardless of hand angle, with the ability to maintain suction without continuous hand pressure, enhancing usability and convenience.
Implementation Method 1
a piston body that is connected to the gripper tube, embedded in the inner space of the suction body, and selectively generates a negative pressure in the inner space while interlocking with up-and-down motion of the gripping tube

AI summary
The present invention relates to a suction device for foreign substances from the body, which may comprise: a suction body that has an internal space, extends a predetermined length, and is brought into contact with the skin; a gripping tube body that extends from the suction body so as to be able to slide up and down along the outer circumferential surface of the suction body, and which can be wrapped and gripped by hand; and a piston body that is connected to the gripping tube body to be provided in the internal space of the suction body and selectively generates a negative pressure in the internal space while interlocking with the up-and-down motion of the gripping tube body. According to the present invention, foreign substances that penetrated the skin can be quickly sucked and removed through a simple operation.
