Solution Overview

Problem

Observing and tracing primo-nodes in the primo-vascular system is challenging due to their dynamic nature and difficulty in maintaining a fixed position, requiring innovative apparatuses and methods for continuous observation.

Innovation Solution

An apparatus comprising a liquid injection tube and a suction tube, where the liquid injection tube is inserted into the suction tube to hold the primo-node, allowing for stable injection and observation of the primo-node using a micro manipulator and image taker, with a negative pressure source to maintain the suction and facilitate imaging.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a liquid injection tube is inserted into a primo-node for injection, then liquid injection is enabled, but the primo-node cannot be held in a fixed position due to its dynamic nature

Engineering Contradiction:

Improveliquid injection capabilityVSAvoidprimo-node position stability

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The liquid injection tube is nested within the suction tube, forming a combined apparatus where the injection tube is inserted through the suction tube. This nested configuration allows the injection function to be integrated with the holding function, enabling liquid injection while maintaining primo-node stability through suction.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The suction tube acts as an intermediary device that holds the primo-node in a fixed position through suction, while allowing the liquid injection tube to pass through it. This intermediary structure resolves the conflict between needing direct injection access and maintaining position stability.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the primo-node is allowed to move naturally, then its physiological function is preserved, but continuous observation and tracing become difficult

Engineering Contradiction:

Improveprimo-node physiological functionVSAvoidobservation and tracing difficulty

Core Design Contradiction:

ReliabilityVSDifficulty of detecting and measuring

Solution Approach 1:

The suction tube applies preliminary suction to hold the primo-node in a fixed position before observation and injection procedures begin. This preliminary fixation enables continuous tracing and observation without disrupting the node's physiological state during the procedure.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The apparatus allows dynamic adjustment where the suction tube can be applied to hold the primo-node temporarily during observation, while the liquid injection tube can be inserted and removed as needed. This dynamic approach balances fixation for observation with preservation of natural physiological function.

Inventive Principle:

Principle #15Dynamics

3Ease of manufacture

If the liquid injection tube is separate from the suction tube, then each component is simple, but the apparatus cannot simultaneously hold the primo-node and inject liquid efficiently

Engineering Contradiction:

Improvecomponent simplicityVSAvoidinjection and holding efficiency

Core Design Contradiction:

Ease of manufactureVSProductivity

Solution Approach 1:

The liquid injection tube and suction tube are merged into a single integrated apparatus where the injection tube is inserted through the suction tube. This combination allows both functions (holding via suction and injection) to be performed simultaneously in one apparatus, improving efficiency while maintaining relative simplicity of individual components.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

Provided are an apparatus for injecting a liquid into a primo-node and a primo-vascular system tracing system including the apparatus. The apparatus includes a liquid injection tube to inject a liquid into a primo-node of an object, and a suction tube to hold the primo-node to inject the liquid injection tube into the primo-node. The liquid injection tube and the suction tube are formed as one body. The liquid injection tube is inserted into an inner side of the suction tube and an edge unit of the liquid injection tube protrudes to the outside from an inner side of a suction opening of the suction tube.
