How is the dosage or dispensed volume adjusted with treatment pump，and are there variations in dosage options?
The dosage or dispensed volume of a treatment pump can typically be adjusted to meet specific application requirements. Different pumps may offer varying mechanisms for adjusting dosage, and the options available can depend on the design and purpose of the pump. Here's how the dosage or dispensed volume is adjusted with a treatment pump, and the variations in dosage options:
Collar or Twist Mechanism: Many treatment pumps have a collar or twist mechanism located at the base of the pump head. By turning the collar or twisting the base, users can adjust the dosage. Clockwise rotation typically decreases the dosage, while counterclockwise rotation increases it. This is a common mechanism for many treatment pumps, especially those used in the cosmetics and personal care industry.
Locking or Unlocking Feature: Some treatment pumps have a locking feature to prevent accidental dispensing during transport or storage. Users may need to unlock the pump before being able to adjust the dosage.
Click or Ratchet Mechanism: Some pumps feature a click or ratchet mechanism that produces a distinct clicking sound as the dosage is adjusted. Each click corresponds to a specific volume increment, making it easier to set a precise dosage.
Multi-Dose or Variable Dose Pumps: Certain treatment pumps are designed for multi-dose applications. Users can adjust the pump to dispense different doses with each actuation. These pumps are commonly used in healthcare, such as for oral liquid medications.
Customizable Dosage Options: In some cases, treatment pumps can be customized to provide specific dosage options, catering to the requirements of the product being dispensed. This customization may be achieved during the manufacturing process.
Low, Medium, and High Dose Settings: Some treatment pumps have predefined settings for low, medium, and high doses. Users can select one of these settings to achieve a consistent dosage each time.
Spray Patterns: For pumps used for sprays or mists, the adjustment may be related to the spray pattern rather than a specific volume. Users can often adjust the spray from a fine mist to a more concentrated stream.
Finger-Pump Mechanism: In some cases, especially for smaller dispensing pumps, users can control the dosage by manually applying varying levels of pressure to the pump head. This is commonly seen in single-use or sample-size pumps.
Precision Dispensing: Some treatment pumps are designed for precision dispensing and are calibrated to deliver exact dosages. These are commonly used in pharmaceuticals and medical applications.
Large Dispensers with Crank or Lever: In industrial or institutional settings, large dispensers may use a crank or lever mechanism to adjust dosage.
The availability of dosage adjustments depends on the manufacturer and the intended use of the treatment pump. It's essential to refer to the product's specific instructions and labeling to understand how to adjust the dosage and what dosage options are available. The dosage options can vary from a fraction of a milliliter to several milliliters, depending on the design and purpose of the pump.
