Syringe Base Nested Assembly Conceals Needle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Exposure of used syringe needles poses a risk of injury and disease transmission to medical professionals, necessitating a solution for safe containment and concealment after use.
Innovation Solution
A syringe assembly comprising a syringe base and support that includes position-limiting and guiding components, allowing secure assembly and concealment of the needle, ensuring stability and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a syringe is used for injection or blood collection, then the medical procedure can be performed, but the needle remains exposed and poses a risk of injury and disease transmission to medical professionals
Solution Approach 1:
The syringe is nested within the syringe support, which is in turn nested within the syringe base. The needle-containing syringe is inserted into the support channel of the base body, and the support body receives the syringe, creating a nested structure that conceals the needle and prevents exposure while maintaining ease of use
Solution Approach 2:
The device is divided into three separate components: the syringe base (base body with abutting component and engaging component), the syringe support (support body with position-limiting component), and the syringe itself. This segmentation allows each component to perform its specific function while working together to contain and conceal the needle
2Reliability
If the syringe base includes multiple components (base body, abutting component, engaging component), then the needle containment and concealment function is improved, but the device complexity increases
Solution Approach 1:
The base body integrates multiple functions: it contains the support channel for receiving the syringe, the position-limiting chamber for guiding the position-limiting component, and the engaging component for securing the syringe support. The abutting component combines the base opening and position-limiting component slot. This merging reduces the number of separate parts while maintaining reliability
Solution Approach 2:
The base body serves multiple purposes: it provides structural support, guides the syringe insertion through the position-limiting chamber, contains the syringe support in the support channel, and prevents needle exposure. The engaging component both secures the syringe support and limits its movement. This multi-functionality reduces overall device complexity while improving reliability

AI summary
A syringe base includes a base body, an abutting component and at least one engaging component. The base body includes a position-limiting portion and has a position-limiting chamber and a support channel. The position-limiting chamber adjoins the position-limiting portion. The support channel is in communication with the position-limiting chamber and penetrates the base body. The abutting component is disposed at an end of the base body and has a base opening and a position-limiting component slot. The base opening is in communication with the support channel. The position-limiting component slot is disposed outside the base opening and adjoins the position-limiting chamber. The engaging component is disposed at the abutting component, protrudes relative to the abutting component and is adapted to bend or rotate relative to the abutting component. A syringe support and a syringe assembly are further provided.
