Appendix D: Technical Variances with MIT
Mechanical design alterations to the MIT design include:
1.
The metal under the bag has been reshaped to increase rigidity to the Resuscitator Mechanism and reduce
abrasion with the bag.
2.
At both ends of the BVM, plastic clips have been added to allow elastic bands to go around the BVM and
hold it in the ideal position. This reduces the risk of the BVM moving out of the intended position.
3.
Under the device, there are rubber feet to reduce the device from moving through vibration or accidental
contact.
4.
The shape and material of the parts that contact the bag and squeeze it have been improved. This reduces
abrasion and prolongs the use of each bag.
5.
Gears and other moving parts have been protected by a cover to reduce the risk of pinch hazards.
6.
Optional: An additional cover has been designed to go over the Resuscitator Mechanism and reduce the
risk of contamination of gears and other difficult to access assemblies. This will make cleaning easier.
Control design alterations to the MIT design include:
7.
The user interface was completely redesigned based on clinical and RRT feedback.
a.
Two separate displays with one showing set parameters and the other showing set alarms. This
enables a clear differentiation between settings and increases the amount of information that
can be displayed at once.
b.
Use of a button and scroll wheel to set variables on the machine. This improves upon MIT’s
design because it prevents confusion on current settings and the corresponding location of the
dials.
c.
Additional indicators of inspiration and expiration though LEDs. Allows the operator to quickly
glance at the machine and determine the current state of ventilation.
d.
An emergency stop button that allows the machine to be disabled immediately.
e.
AC disconnect alarm to indicate loss of power.
8.
Alarms parameters are user selectable.
9.
Addition of power disconnect and power off alarm.
2.
Addition of a remote monitoring display that displays alarms and current readings in large letters. This
enables clinicians to monitor a patient in isolation without donning PPE to enter the room.
