Detailed Introduction of Nasal Drug Delivery Device

1. Product Overview

The nasal drug delivery device is a professional medical auxiliary instrument specially developed for transnasal targeted administration. Taking advantage of the rich capillary distribution and good permeability of human nasal mucosa, it delivers liquid medicines evenly to the lesion site inside the nasal cavity. It can replace traditional manual dropping to achieve quantitative, directional and uniform administration. This product is widely used in clinical ENT treatment, postoperative nasal care, daily nasal medication and nasal cavity cleaning, suitable for adults, teenagers and children under proper guidance.

2. Main Raw Materials

All contact parts that touch liquid medicine adopt medical-grade PP, PE and silicone materials. The raw materials are non-toxic, tasteless, free of heavy metal precipitation and plasticizer overflow, non-irritating to fragile nasal mucosa, in line with medical contact safety standards. The shell material has good toughness, fall resistance and stable chemical property, which will not react chemically with conventional nasal liquid preparations such as normal saline, anti-inflammatory solutions, anti-allergy liquids and nasal repair gel.

3. Structural Design & Working Principle

Structure Composition

• Pressing pump head: Control the output dosage accurately in one press to realize fixed-quantity spraying or dripping;
• Sealing assembly: High-performance sealing ring effectively prevents liquid leakage during extrusion, transportation and storage;
• Curved nasal nozzle: Ergonomically bent design that fits the physiological radian of the nasal cavity; the outlet is smooth and round without sharp edges to avoid scratching nasal mucous membrane;
• Working Principle

The liquid medicine is pumped to the nozzle through the suction tube, then atomized into fine mist or output in a slow and uniform liquid column. The medicine can cover the nasal wall comprehensively instead of directly flowing down the throat, greatly improving the contact time between drugs and nasal mucosa and the utilization rate of medicines.

4. Core Product Advantages

1. Accurate quantitative administration Fixed single dosage output avoids excessive or insufficient medicine caused by hand shaking during manual dripping, ensures stable therapeutic effect and reduces drug waste.
2. Gentle and mucosal-friendly administration Soft mist spraying reduces strong impact on inflamed, swollen or damaged nasal mucosa; the rounded nozzle will not cause secondary scratch damage during insertion.
3. Simple self-operation Light weight and compact structure. Users can complete nasal administration independently without assistance from medical staff after learning simple operation steps, convenient for home long-term medication.
4. Excellent sealing and anti-leakage performance Multi-layer sealing structure can effectively prevent liquid leakage when carried in bags, pockets during travel and daily going out; the internal pipeline is smooth to reduce residual liquid dirt and bacterial breeding.
5. Wide compatibility Applicable to most water-based liquid nasal preparations: physiological seawater nasal care liquid, allergic rhinitis anti-allergy liquid, postoperative nasal anti-inflammatory lotion, nasal mucosa repair solution, antibacterial nasal care liquid and other liquid medicines.

5. Main Application Scenarios

1. Hospital clinical scenarios Otolaryngology routine drug delivery, nasal cavity postoperative cleaning and nursing, auxiliary treatment of sinusitis, hypertrophic rhinitis and allergic rhinitis;
2. Pharmacy supporting matching Supporting packaged nasal liquid medicines as matched administration tools for standardized medication;
3. Household daily nursing Long-term regular medication for patients with chronic rhinitis, daily nasal cleaning for people working in dusty environments, relief of nasal dryness and congestion;
4. Outdoor portable use Small size and portable design, suitable for business trips, travel and outdoor emergency nasal care.

6. Standard Operation Steps

1. Open the outer cap of the device, install the pump head tightly on the liquid storage bottle and tighten it clockwise;
2. Shake the liquid medicine gently to make the medicinal components evenly mixed;
3. Tilt the head slightly backward, insert the nozzle gently into one nostril; block the other nostril slightly with one finger;
4. Press the pump head vertically once steadily, inhale gently through the nose during pressing to help the mist fully enter the deep nasal cavity;
5. Repeat the operation for the other nostril; wipe residual liquid around the nostrils with clean tissue after use; cover the protective cap to avoid nozzle contamination.

7. Storage & Maintenance Notes

1. Store in a cool, dry place away from direct sunlight, high temperature and corrosive gas;
2. After each use, cover the protective cap in time to prevent dust and bacteria from contaminating the nozzle outlet;
3. For reusable models, clean the nozzle and bottle body with warm boiled water regularly, air-dry naturally before next use; do not use high-temperature boiling disinfection to prevent deformation of plastic parts;
4. Stop using immediately if cracking, aging, sealing failure or nozzle blockage occurs;
5. Keep away from infants to prevent accidental swallowing or improper insertion injury.
