Bite Block with Integrated Gas Delivery and Sampling Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During upper endoscopy procedures, patients often bite down on the endoscopic tube, potentially damaging it, and there is a need for a solution that can provide gases to the subject and sample exhaled gases for monitoring without interfering with the procedure.
Innovation Solution
A bite block assembly comprising a bite block with a mouthpiece and a nasal cannula assembly that delivers gases and samples exhaled gases, featuring a main channel for the endoscopic tube, a sampling channel for exhaled gases, and a nasal cannula manifold with prongs and a scoop to direct gases to a gas monitoring device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bite block is used to prevent the patient from biting the endoscopic tube, then the endoscopic tube is protected from damage, but the patient's ability to receive gases and have exhaled gases sampled is compromised
Solution Approach 1:
The bite block is designed with multiple functions: it protects the endoscopic tube from biting damage while simultaneously incorporating gas delivery channels and exhaled gas sampling capabilities. The mouthpiece contains both a main channel for the endoscope and a sampling channel for gases, allowing the single device to fulfill protective, respiratory, and monitoring roles
Solution Approach 2:
The invention merges the bite block protection function with the gas delivery and sampling functions into a single integrated assembly. The nasal cannula assembly is combined with the bite block to create a unified device that performs multiple functions simultaneously, eliminating the need for separate devices
2Adaptability or versatility
If a separate gas delivery system is added to the bite block, then gas delivery and sampling capabilities are improved, but the device complexity increases
Solution Approach 1:
The gas delivery tubes and sampling channels are nested within the bite block structure. The nasal cannula assembly is integrated into the bite block, with components arranged concentrically and hierarchically to minimize space requirements and reduce overall device complexity while maintaining full functionality
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 assembly effectively prevents the patient from biting the endoscopic tube while allowing for the delivery of gases and sampling of exhaled gases, enhancing the safety and monitoring capabilities during endoscopic procedures.
Implementation Method 1
a rib extending outward from and along a portion of the first surface of the body, the rib defining a fluid passage configured to receive and direct said orally exhaled gases towards the opening of the nasal cannula manifold
Implementation Method 2
a scoop configured to be connected to the nasal cannula manifold and direct said orally exhaled gases from the sampling channel of the bite block to the opening of the nasal cannula manifold
Implementation Method 3
a first gas delivery tube connected to the first end of the nasal cannula manifold and in fluid communication with the first interior portion of the nasal cannula manifold; a first nasal prong in fluid communication with the first interior portion of the nasal cannula manifold and configured to direct gases from the first gas delivery tube into a first nostril of the subject
Implementation Method 4
The gas sampling tube can be connected to the second end of the nasal cannula manifold and in fluid communication with the second interior portion of the nasal cannula manifold. The gas sampling tube can be configured to direct said gases exhaled from the second nostril and said orally exhaled gases to a gas monitoring device

AI summary
A bite block includes a main body and a mouthpiece extending outward from the main body and configured to be positioned in a mouth of the subject when the bite block is in use. The mouthpiece can include a main channel configured to receive an endoscopic tube and a sampling channel configured to receive orally exhaled gases from the subject. The bite block can include a gas delivery channel configured to direct gases into the subject's mouth, the gas delivery channel extending through a portion of the main body and through a portion of the main channel such that the gas delivery channel is in fluid communication with the main channel. The bite block can include a recess extending along a portion of the first surface of the main body proximate the gas delivery channel and configured to receive a portion of a gas delivery tube.
