ABSTRACT
Now, a number of beds in National Hospital of Pediatrics are huge but all have not
integrated scales. Weight parameter is very important in the treatment process for patient.
Using the integrated scales in bed facilitates for doctor in taking patient weight without
affecting the patient being treated in a patient bed. in this thesis we design and
manufacture integrated scales for infant incubator. The requirements of this system
include:
- Designing the scale to weigh thepatient the most accurate way.
- Printing the weight parameters of patient and time on printing paper.
- Designing compact, aesthetic mechanical structure and fit with the mechanical
structure using incubator.
After completing the group has conducted calibration to get the most accurate
results for products. The results after the finished product obtained:
- Creating the scale with the error of less than 1%, the main functions are SET,
UP, DOWN, PRINT / ESC, ON / OFF.
- Weight parameter and time printed on paper with clear display.
- Mechanical system and control box go with mechanical structure of the current
incubator.
