Nasal Spray Apparatus Atomizing Medicament for Deep Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spray technologies for veterinary and human medical applications are inefficient and uncomfortable for animals, particularly when administering vaccines or medicaments to the nasal cavity, as they often require long tubes that cause adverse reactions and suboptimal delivery.
Innovation Solution
A spray apparatus comprising a base and cap member connected to a fluid supply, designed to deliver a predetermined dose of liquid medicament or vaccine efficiently and comfortably by atomizing the fluid into a small droplet spray pattern, eliminating the need for long tubes and minimizing adverse reactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional spray technologies use long tubes to deliver fluid to the nasal cavity, then the fluid can reach the target area, but the animal experiences adverse reactions and discomfort
Solution Approach 1:
The patent removes the long tube component from the spray system entirely. Instead of using a traditional long catheter or tube to reach the nasal cavity, the invention employs a short sprayer assembly that delivers fluid through a different mechanism - using the animal's own nasal airflow to propel the spray deep into the nasal passages without requiring physical insertion of long tubes.
Solution Approach 2:
Conventional approaches push fluid through long tubes against resistance. This invention inverts the approach by using the animal's inhalation airflow to pull or propel the spray forward naturally. The sprayer positions the fluid delivery at the entrance of the nasal cavity and lets the animal's own breathing mechanics do the work of delivering the medicament deep inside, rather than forcing it through a long tube.
2Productivity
If conventional methods deliver liquid medicament to the nasal cavity, then treatment is provided, but delivery efficiency and coverage are suboptimal
Solution Approach 1:
The patent changes the physical parameters of fluid delivery by atomizing the liquid medicament into a fine spray with specific droplet size distributions. This atomization process creates numerous small droplets that can be carried efficiently by nasal airflow, improving both delivery speed and distribution coverage compared to delivering bulk liquid through long tubes.
Solution Approach 2:
The invention utilizes pneumatic principles by harnessing the animal's nasal airflow (a gas flow) to transport the liquid spray deep into the nasal cavity. The design positions the spray delivery to work with rather than against the natural airflow patterns, using the animal's own breathing mechanics to achieve deep and consistent delivery without mechanical pumping through long tubes.
3Volume of moving object
If long tubes are used for spray delivery, then fluid can reach deep into the nasal cavity, but the device complexity and animal discomfort increase
Solution Approach 1:
The patent extracts and eliminates the long tube component from the device structure. The sprayer assembly is designed to be very short, positioning the spray nozzle at the entrance of the nasal cavity. The depth penetration is achieved not by physical length of the device but by using aerosolized droplets that can be carried by airflow deep into the nasal passages, thereby simplifying the device structure significantly.
Solution Approach 2:
The invention changes the physical state and size parameters of the delivered fluid - converting liquid medicament into fine aerosol droplets. This parameter change allows the medicament to reach deep into the nasal cavity as a dispersed phase carried by airflow, rather than requiring a long physical conduit to transport bulk liquid, thus reducing device complexity while maintaining penetration depth.

AI summary
A spray apparatus adapted to be connected to a fluid supply such as a syringe to spray a predetermined pattern of spray fluid to a target area such as the tissues of an animal or human. The sprayer delivers a predetermined dose of a medicament, vaccine or the like to the nasal or other cavity of an animal or human patient. The sprayer includes a base member and a cap member which is connected to the base member. The base member is connectible to the fluid supply. Spray is discharged from the distal or outward end of the cap member. The base member has a central, longitudinal lumen having a predetermined configuration. Fluid traverses the lumen and is discharged through a central aperture of the cap, which also has a predetermined configuration. The cap central lumen and spray discharge aperture are aligned with the base lumen.
