Automated gauze counting bin using photoelectric sensor

Problem: Human error of counting number of gauge pads being used during a surgery.

NEED Statement: Introduce a bin attached with photoelectric sensor for counting to reduce human error and workload of nurse

Beneficiary: Surgeon, Circulating nurse, Scrub nurse

Description:

The photoelectric sensor consists of a receiver and a transmitter
When a gauze pad is dropped inside the bin, the light from the transmitter to the receiver gets interrupted
This signal triggers the microcontroller to increment the count. The display unit attached to the microcontroller displays the value of number of gauze pads in the bin.
An option to reset via microcontroller

Result:

The photoelectric sensor will assist the nurse to count gauze pad in the bin
Less chance of human error as sensor will automatically detect the pads when it falls into the bin
Reduced workload for nurse
