Multidirectional Atomizing Nozzle Head With Retention Cap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical instruments for spraying fluids into body cavities lack the ability to spray multidirectionally, leading to uneven distribution and potential safety risks due to unsecured nozzle bodies being blown out by high-pressure fluids.
Innovation Solution
A tool with a nozzle head featuring multiple lateral and distal nozzles, secured by a cap with smaller through-openings, allowing for multidirectional atomization and preventing nozzle displacement during high-pressure fluid application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a unidirectional spray device is used to deliver fluid into a body cavity, then the device structure is simple, but the fluid distribution is poor and cannot reach all areas of the cavity
Solution Approach 1:
The spray device is divided into multiple independent spray heads (first spray head, second spray head, etc.), each capable of spraying fluid in different directions. This segmentation allows the fluid to be delivered to multiple areas of the body cavity simultaneously, improving coverage without requiring a single complex multi-directional mechanism
Solution Approach 2:
The patent transitions from unidirectional spraying to multidirectional spraying by arranging spray heads at different orientations (e.g., first spray head at 45 degrees, second spray head at 135 degrees). This dimensional change in spray direction enables comprehensive coverage of the body cavity from multiple angles
2Adaptability or versatility
If the spray device needs to navigate complex body cavity paths to reach all areas, then coverage is improved, but the procedure time increases
Solution Approach 1:
Multiple spray heads are positioned to spray in different directions simultaneously, allowing fluid to reach multiple cavity areas at the same time rather than requiring sequential navigation to each area. This parallel delivery significantly reduces procedure time while maintaining comprehensive coverage
Solution Approach 2:
The multidirectional spray configuration enables continuous and simultaneous fluid delivery to multiple cavity regions, eliminating the need to stop and reposition the device repeatedly. The useful action of fluid delivery continues uninterrupted in multiple directions concurrently

AI summary
The present invention relates to a tool (1) for a medical instrument for the multidirectional atomising of a fluid into a cavity of a body, and to a medical instrument herefore. The tool (1) has a shaft (2) with a lumen (7). At the distal end (1') thereof, a nozzle head (3) is arranged, which has at least two lateral nozzles (4) and one distal nozzle (5) that is arranged on a distal end face (3') of the nozzle head (3). Each nozzle has a nozzle opening (4',5') that is fluidically connected to the lumen (7) via a distributor cylinder (10). A cap (6) is releasably arranged around the nozzle head (3), which cap has, for each of the nozzles (4, 5), a through opening (6') which can be positioned over their nozzle opening (4', 5') and which is designed to allow the discharge of a stream of the fluid to be atomised, wherein the through openings (6') of the cap (6) each have an opening cross section that is smaller than a diameter of the respective nozzle (4, 5) positioned under the through opening (6').
