How to clean the mist storage tank
Nebulizers are commonly used auxiliary inhalation devices for asthma patients, which can help drugs be deposited into the lungs more effectively. However, after long-term use, drug residues, dust and bacteria will accumulate inside the spray tank, which will affect the use effect and may even cause infection. Therefore, it is important to clean the spray tank regularly. This article will introduce the cleaning steps, precautions and related data in detail to help you correctly maintain the mist storage tank.
1. Cleaning frequency and necessity
According to Global Initiative for Asthma (GINA) guidelines, spacers should be cleaned at least once a week or simply rinsed after each use. The following are cleaning suggestions for different usage scenarios:
| Frequency of use | Recommended cleaning cycle |
|---|---|
| Daily use | Deep clean at least once a week |
| Use occasionally | Rinse after each use |
| Not used for a long time | Wash thoroughly before use |
2. Detailed explanation of cleaning steps
1.Disassembly parts: Separate the various parts of the mist storage tank (such as mask, valve, tank body) to ensure that each part can be cleaned independently.
2.Rinse with warm water: Rinse all parts with warm water (not exceeding 40℃), avoid using hot water to avoid deformation. Never use brushes or sharp objects to scratch.
3.Soak in neutral detergent: Soak the parts in a dilute neutral detergent solution (such as dishwashing liquid) for 10-15 minutes. The following are recommended ratios of detergents:
| Cleaner type | Water to detergent ratio |
|---|---|
| liquid dishwashing detergent | 500ml water + 1 drop |
| Special instrument cleaner | Prepare according to instructions |
4.Rinse thoroughly: Rinse all parts with running water to ensure there is no detergent residue.
5.Let dry naturally: Place the parts on a clean towel to air dry naturally, avoid direct sunlight or wiping. Drying time reference:
| environmental conditions | Estimated drying time |
|---|---|
| Room temperature (25℃) | 2-4 hours |
| Well ventilated | 1-2 hours |
6.Assembly inspection: Reassemble after complete drying and check whether the valve is flexible and sealing is good.
3. Common mistakes and precautions
1.Avoid high temperature sterilization: Spray storage tanks are mostly made of plastic material. High-temperature steam or boiling will cause deformation. The following is a reference for material temperature resistance:
| Material type | Maximum temperature resistance |
|---|---|
| Ordinary plastic | 60℃ |
| Medical grade PP | 80℃ |
2.Alcohol wiping is prohibited: Alcohol may corrode plastic parts or affect the effectiveness of medications.
3.Regular replacement: Even if cleaned correctly, the spray tank needs to be replaced regularly. Recommended replacement cycles for different brands:
| brand | Recommended replacement cycle |
|---|---|
| Philips | 6-12 months |
| PARI | 12 months |
4. Tips for maintenance of mist storage tanks
1. Turn it upside down and drain immediately after each use to prevent drug crystallization from clogging the valve.
2. To avoid extrusion and deformation during storage, it is recommended to use a special storage box.
3. Check regularly for cracks or signs of aging and replace in time.
5. Expert advice
Professor Wang, Director of the Respiratory Department of Peking Union Medical College Hospital, pointed out: "In clinical practice, the problem of decreased inhalation efficiency caused by improper cleaning of aerosol storage tanks is common. Proper cleaning can increase the drug deposition rate by 15%-20% and reduce the risk of respiratory tract infections."
Through the above structured data and detailed steps, we hope to help you scientifically maintain the spray tank and ensure the effectiveness of treatment. If in doubt, it is recommended to consult your treating physician or medical device supplier for personalized guidance.
