【Case Study】Nasal Irrigator Registration in China

from CIRS by

1. Introduction

Product Name: nasal irrigator, nasal wash

Product Composition: consists of a main unit, a water tank, a nasal wash (adult and child type), and a power adapter.

Working Principle:

After the nasal irrigator is energized, the motor converts the electrical energy into mechanical pressure. The pressure is used to deliver warm water/physiological saline into the nostrils, through the nasal vestibule, sinus, and nasal passages around the nasopharynx, and from the other side of the nostrils. Through the above path, the sterilizing action of the physiological saline itself and the impact force of the water flow are used to discharge the accumulated dirt and harmful substances in the nasal cavity, thereby achieving the purpose of cleaning and daily care of the nasal cavity.

Typical Structure:

Nasal Irrigator

Scope of application: For nasal irrigation and daily nasal hygiene

Applicable people: Suitable for adults and children with nasal cleansing needs

2. Classification

Classification Code: 14-07-01 Class II Flushing device

Product Description: Usually composed of a host, a heating module, and a power module

Expected Usage: For rinsing the natural cavity (excluding vaginal), rinsing the tissue during and after surgery, and warming the rinsing fluid

3. Registration Unit

1. Different principle

Passive polymer material nasal irrigators and active electric irrigators cannot be registered together.

2. Sterile and non-sterile

The polymer material type irrigator is a class II device provided by sterilizing, and a class I device provided by non-sterile; the electric nasal lavage device is class II.

3. Whether it contains drugs

Separate registration with medicinal ingredients and without drugs.

4. Technical Requirements

1. Appearance

The appearance of the nasal irrigator should be neat, smooth and uniform in color; no defects such as sharp edges, burrs, cracks, etc.; the characters and signs on the panel should be clearly visible; the installation and connection parts should be tight, the movable parts should be used, the rotation is flexible and reliable; the water tank is leak-free. .

2. Tank capacity

The water tank capacity is 700ml.

3. Flushing pressure

The water pressure at the outlet of the nasal wash should be between 0.1 MPa and 0.3 MPa.

4. Flushing flow rate

The water flow rate at the outlet of the nasal wash should be no more than 10 ml/s.

5. Flush height

The outlet height of the adult nasal wash outlet is 4.0 cm ± 1.0 cm; the height of the child's nasal wash outlet is 2.0 cm ± 1.0 cm.

6. Irrigator piping system effluent chemical properties

6.1 pH

The difference between the pH of the eluate and the blank control solution should be ≤1.0;

6.2 Heavy metal content

The heavy metal content of the eluate should be ≤1.0 μg/mL.

7. Electrical safety requirements

Should meet the requirements of GB9706.1-2007.

8. Electromagnetic compatibility requirements

Should meet the requirements specified in YY 0505-2012.

9. Environmental test requirements
