SUMMARY

The discussion centers on designing an air mattress capable of lifting a patient weighing 200kg, with dimensions of 1000mm x 610mm x 250mm. To calculate the necessary pressure for inflation, users must understand the relationship between mass, area, and pressure, as defined in the pressure formula. The maximum flow rate from the blower is specified at 700 liters per minute (lpm), but additional specifications are required to accurately determine the fill time for varying patient weights.

PREREQUISITES
  • Understanding of pressure calculations and units
  • Knowledge of airflow dynamics and blower specifications
  • Familiarity with basic physics concepts related to mass and area
  • Ability to interpret technical specifications of pneumatic devices
NEXT STEPS
  • Research the formula for calculating pressure: P = F/A
  • Investigate how to determine fill time based on blower specifications
  • Explore the impact of varying patient weights on pressure requirements
  • Learn about pneumatic systems and their applications in medical devices
USEFUL FOR

Engineers, product designers, and healthcare professionals involved in the development of medical equipment, particularly those focused on patient lifting and support systems.

Hey guys,

I am to design an air mattress to lift a patient of about 200kg.
The dimensions of the mattress is 1000mm x 610mm x 250mm.
The max flow rate from blower is 700lpm.

What and how should i calculate the pressure with which i need to fill the mattress?
Also, how to calculate the time required to fill for different patient weights?

Thanks

Is this homework? Please use the homework template.

Do you know the definition & units of pressure? You have a mass and can estimate an area so can solve for pressure.

You cannot find fill time without more blower specs.
