Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ear canal cleaning methods require medical staff to manually hold a syringe and a basin, distracting them from the cleaning process and making it inconvenient and inefficient.
Innovation Solution
An ear-cover structure with a containing space, injection port, and leakage port that allows for efficient alignment of the syringe nozzle with the ear canal and facilitates fixed-point drainage, reducing the need for manual basin holding and improving ergonomic handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If medical staff manually hold a syringe and a basin during ear canal cleaning, then the cleaning process can be performed, but the medical staff is distracted from the cleaning process and operational efficiency deteriorates
Solution Approach 1:
The patent combines the syringe holder and basin into a single integrated device. The syringe holder includes a receiving cavity that accommodates the syringe, while the basin is positioned below to collect discharged liquid. This merging eliminates the need for separate manual handling of both items, allowing medical staff to perform cleaning with one hand while the other hand remains free for observation and control.
Solution Approach 2:
The patent introduces an intermediary structure (the integrated device with guide channel and collection chamber) that mediates between the syringe and the medical staff. The guide channel directs the flow of cleaning liquid, and the collection chamber automatically accumulates discharged liquid, removing the need for direct manual intervention in both injection and collection processes.
2Reliability
If medical staff pay attention to multiple items simultaneously during cleaning, then the cleaning process can be monitored, but the medical staff is distracted from serious medical care operations
Solution Approach 1:
The patent merges the monitoring functions into the integrated device structure. The transparent or translucent collection chamber allows visual monitoring of liquid accumulation, while the guide channel ensures proper liquid flow direction. This design enables automatic monitoring without requiring continuous manual attention from the medical staff.
Solution Approach 2:
The device performs self-monitoring through its structural design. The collection chamber visually indicates liquid levels, and the guide channel automatically directs liquid flow, reducing the need for active monitoring by the medical staff while maintaining reliability of the cleaning process.
3Productivity
If a syringe is used to spray saline into the ear canal, then the ear canal can be flushed, but the medical staff must hold the syringe and observe the liquid position, making the process inconvenient
Solution Approach 1:
The patent combines the syringe holder, guide channel, and liquid collection chamber into a single integrated unit. The syringe holder securely positions the syringe, the guide channel directs liquid flow, and the collection chamber accumulates discharged liquid. This integration allows the medical staff to perform the cleaning operation with one hand while maintaining ease of operation.
Solution Approach 2:
The guide channel acts as an intermediary that automatically directs the cleaning liquid from the syringe into the ear canal and then to the collection chamber. This intermediary structure eliminates the need for manual positioning and observation of liquid flow, improving both productivity and ease of 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
Enhances the accuracy and convenience of ear canal cleaning by allowing the syringe nozzle to be aligned easily with the ear canal and enabling fixed-point drainage, reducing the operational intensity of medical staff and improving the overall cleaning process.
Implementation Method 1
Under the action of gravity, the cleaning liquid flowing out from the ear canal is collected in the liquid collecting portion and discharged from the leakage port of the liquid collecting portion to the external environment
Data Source
AI summary
The present application discloses an ear-cover structure and an ear irrigation device. The ear-cover structure includes a cover configured with a containing space with an opening configured at a side of the containing space, a liquid collecting portion extending outwards from the bottom of the cover, and an injection port configured on the cover and communicating with the containing space. The medium collected in the containing space flows through the liquid collecting portion and is discharged from a leakage port to the external environment.
