Bronchoscopy Scope Guide for Non-Invasive Ventilation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During bronchoscopy procedures, the bronchoscopy scope can increase airway resistance, causing patient discomfort or respiratory distress, especially in patients receiving positive pressure ventilation, and the use of non-invasive ventilation masks complicates the insertion of the scope due to the distance of the guiding hand from the nasal or mouth opening, leading to bending or looping of the scope.
Innovation Solution
A bronchoscopy scope guide comprising a semi-rigid scope guide tube with a bronchoscopy scope seal and a semi-rigid grommet, allowing pivotal movement to position the distal end of the exit guide portion proximate to the nasal or mouth opening, preventing undesirable bending or looping of the scope within the patient interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a non-invasive ventilation mask is used during bronchoscopy, then positive pressure ventilation can be maintained, but the guiding hand is positioned 2-3 inches away from the nasal or mouth opening causing the scope to bend or loop
Solution Approach 1:
A guide tube is introduced as an intermediary device between the mask port and the patient's airway. The guide tube extends through the mask port and positions its distal end near the nasal or mouth opening, providing a stable pathway that eliminates scope bending and looping while allowing the physician to guide the scope from the mask port location.
2Adaptability or versatility
If the bronchoscopy scope is fed through the mask port, then the procedure can be performed through NIV mask, but the scope bends or loops inside the mask making insertion difficult
Solution Approach 1:
The guide tube serves as a mediator that creates a stable, pre-positioned pathway through the mask port to near the patient's airway entrance. This intermediary structure eliminates the bending and looping problems by providing mechanical support and proper routing for the bronchoscopy scope throughout the insertion process.
3Stability of the object's composition
If the guiding hand is placed at the mask port entrance, then the mask structure is maintained, but the distance from the nasal or mouth opening reduces control leverage
Solution Approach 1:
The guide tube acts as an extension that transfers the physician's control from the mask port location to the distal end near the patient's airway. This intermediary structure maintains mask integrity while restoring full control leverage by allowing the physician to manipulate the scope at the optimal position.
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
The scope guide assists in guiding the bronchoscopy scope to the correct location, reducing patient discomfort by minimizing scope bending and looping, thus facilitating the procedure while maintaining positive pressure during non-invasive ventilation.
Implementation Method 1
The bronchoscopy scope seal couples to the scope guide tube for sealing between the scope guide tube and around a bronchoscopy scope, in response to the bronchoscopy scope being inserted through the scope guide tube. The bronchoscopy scope seal further enables maintaining of a positive pressure within the patient interface during usage of the patient interface for non-invasive ventilation.

AI summary
A bronchoscopy scope guide (30) for a non-invasive ventilation (NIV) patient interface (10) comprises a semi-rigid scope guide tube (32), a bronchoscopy scope seal (48), and a semi-rigid grommet (34). The semi-rigid scope guide tube (32) includes a principal axis (36) and entrance and exit guide portions (38,40). The bronchoscopy scope seal (48) couples to the scope guide tube for sealing around a bronchoscopy scope when inserted through the scope guide tube. The semi-rigid grommet (34) is disposed about an outer circumference of and flexibly coupled to the scope guide tube (32) and is located in a principal plane (52) transverse to the principal axis of the scope guide tube. The scope guide tube (32) is pivotally manipulate-able about the flexible coupling of the grommet (34) for positioning a distal end (46) of the exit guide portion of the scope guide tube proximate, but not in contact with, one of a nasal cavity or mouth opening of a patient for assisted guidance control of the bronchoscopy scope within an interior region (58) of the patient interface (10) in performance of a bronchoscopy procedure.
