Abstract:
To disassemble the suction unit and study its different parts and the mechanisms
involved.
Introduction:Devices are sometimes necessary to create suction. Suction may
be used to clear the airway of blood, saliva, vomit, or other secretions so that a
patient may breathe. Suctioning can prevent pulmonary aspiration, which can
lead to lung infections .In surgery suction can be used to remove blood from the
area being operated on to allow surgeons to view and work on the area. Suction
may also be used to remove blood that has built up within the skull after an
intracranial hemorrhage .Suction devices may be mechanical hand pumps or
battery or electrically operated mechanisms. Suction pumps are mostly used for
pulmonary hygiene.
Tools Required:Hand,screw drivers of different sizes.
Working Mechanism:The pump of the suction unit sucks in the air from the
jars and sends it out through the air remover hole. As a result, a vacuum is
generated within the jars which in turn sucks the fluid into the jars.
One of the jars has a floater valve which cuts off the pressure once the maximum
level of fluid is reached. Jars with various capacities are available. The significance
of the floater valve is defeated when frothing happens.

Geometric Layout:
Possible Improvements:A Castor ball can be used in place for the front
wheel for ease of motion in all directions. There is no necessity for two
jars. It can be replaced by a single jar of enough quantity/volume .The
cut-off mechanism can be made better as the floater valve fails when
frothing happens.A Castor ball can be used in place for the front wheel

Conclusions:In this experiment, we first disassembled the product in
order to perform product analysis by reverse engineering process. The
tool used for disassembling was screwdriver. Based on this exercise we
made part-list of the product comprising of part name and material. We
also listed the function of each part and prepared the function

structure of the product. We had a group discussion on the product in
order to increase our understanding of it.
From this experiment we learnt to use various tools. This exercise was a
good example of product analysis by reverse engineering process. We
learnt the various parts of a suction unit and their functions. We also
learnt the manufacturing and production of these components. We
learnt how the various modules of the suction unit function, and
interact with each other
