Nasal Delivery Trainer With Multisensory Actuation Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Nasal drug delivery devices are difficult to use properly without proper training, leading to errors such as insufficient force for actuation, accidental actuation, and uncertainty about dose delivery, which affects patient compliance and confidence in self-administration.
Innovation Solution
A nasal drug delivery training device that incorporates multi-sensory learning features, including visual, auditory, and somatic stimuli to simulate the correct use of nasal drug delivery devices, enhancing user confidence and accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If nasal drug delivery devices are designed to deliver precise dosages with multiple steps, then medication effectiveness is improved, but device complexity and difficulty of use increase
Solution Approach 1:
The training device allows patients to practice the multi-step nasal delivery process before actual medication administration. By performing preliminary actions in a safe training environment, patients learn the precise timing and force requirements without risk, thereby improving reliability of actual medication delivery while the device complexity remains managed through separate training and actual device components
2Measurement precision
If nasal drug delivery devices require precise timing and force for actuation, then dosage accuracy is improved, but ease of operation deteriorates
Solution Approach 1:
The training device incorporates visual, auditory, and tactile feedback mechanisms that provide real-time information to patients about their actuation force and timing. This feedback loop guides patients to achieve precise dosage delivery while making the learning process easier, as they can immediately see and hear whether their actions are correct, thereby improving dosage accuracy without permanently worsening ease of operation
Solution Approach 2:
The training device creates a simplified copy of the actual nasal delivery device that replicates the key actuation mechanics and feedback signals. By practicing on this copy, patients learn the precise timing and force requirements in a lower-stakes environment, improving their ability to operate the actual device accurately while the training copy itself remains simple to manufacture and use
3Reliability
If patients are required to carry multiple medicaments for repeated doses, then treatment effectiveness is improved, but patient compliance deteriorates
Solution Approach 1:
The training device enables patients to practice administering multiple doses in sequence before actual treatment situations arise. By performing preliminary practice sessions, patients become familiar with carrying and using multiple medicaments, reducing anxiety and improving compliance. The training shows patients that carrying two epinephrine auto-injectors is manageable, thereby improving patient compliance while maintaining treatment effectiveness

AI summary
In at least one embodiment, there is provided a nasal drug delivery training device for training a subject to deliver medicament to a nasal airway, including a pre-use position and a post-use position, a housing comprising a cavity, a proximal end, and a distal end, and a nasal interfacing portion near the proximal end. The device includes a plunger moveable relative to the housing, said plunger having a retracted position, and an extended position, and a plunger biasing member associated with the plunger for resetting the plunger to the extended position post use, wherein movement of the plunger toward the proximal end of the housing simulates delivery of medicament to a nasal airway with a nasal drug delivery device.
