HLTSTE005- Assignment 1
What you have to do
This unit is concerned with the essential knowledge required to follow correct procedures for preparing, handling and inspecting reusable medical devices. This includes the knowledge to identify instruments that require insulation testing and understand those items requiring disassembling and re-assembly.
Answer all knowledge questions below. Type your answers in the fields provided. Save your answers in this document then submit via the OLS.
You may need to refer back to your learning resource.
1.
What lubricate is suitable for lubricating instruments and is safe for sterilization?
All water soluble lubricants are suitable for lubricating instruments and sterilisation as
they allow steam penetration.
2.
What is classified as loan equipment?
Any. single or complete set of items not owned by the hospital and have beeen loaned for usage with the purpose of returning to the supplier
3.
You are inspecting instruments for packing when you come across a faulty instrument, what is the correct requirement for instrument repair?
The instrument should be removed immediately and workplace procedures and policies followed for reporting and documenting and the equipment should be sent to be repaired.
Your workplace should have a detailed instrument repair program in place and the instrument repair company contacted, this would allow for the instruments to be repaired properly and returned.
4.
Why is leak testing required for an endoscope?
Leak testing for endoscopes are very important to protect paitents from infection. If fluid leaks into the scope it can cause damage to the fibreoptic, image bundles and video chips. This could cause stiffness and loss of angulation capabilities. This would
then lead to expensive repairs.
5.
What procedures can we follow to ensure microsurgical instruments are not damaged during the reprocessing?
Most importantly follow manufacturers reccommendations and take extreme care. You must use special perforated tray with clip inserts for mechanical cleaning. Instruments should always be seperated and not stacked, when sterilising or stored they are to be in perforated trays with lids.

6.
You received a loan set that requires priority processing there will not be enough time
for the set to go through every step of the process, theatres are asking you to have it ready for the next case Do you take shortcuts after all the set looks clean? List the correct steps you will follow.
Short cuts are never acceptable. On arrival loan sets should be thoroughly checked for damage, cleaned and processed before sterilisation by the wrapped method.
Any instrument that isnt clean should be reported to the supplier. Check delivery documents and follow suppliers information and instructions for each piece of equipment.
After usage all loan equipment should be cleaned and sterilised before returning it to the supplier
7.
How are telescopes checked after they have been cleaned?
You will need to look through the eye piece towards the light to check that the telescope lens is clear, if it appears foggy or is damaged it would need to be sterilised and sent out for repairs.
8.
Why is it important to follow manufacturer’s instructions for soaking any instruments in enzyme solution?
It is important to follow manufacturers instructions to avoid injury to staff or paitents. With its ability to break down proteins this raises concerns about inhalation of enzymes which can result in asthma or allergic effects.
9.
What do you need to do with a dental hand piece at the end of each procedure? At the end of each procedure the hand piece needs to be changed, to discharge water and air for atleast 30 seconds or follow manufacturers instructions. This will ensure any gross debris will be distrubed.
10. What is the correct procedure for cleaning a light lead? Fibre optic light leads should be handled with care to protect the fine glass rods. They should be manually cleaned with a soft lint free cloth with the appropiate cleaning chemicals. A neutral or mild alkali detergent diluted in water, then gently rinse manufacturers instructions should always be referred to.
11. Write down the correct procedure for cleaning a power drill.
Power drills should be inspected before cleaning or sterilisation. A cabinet or exhaust
hood should be used to reduce exposure from aerosols. They should never be immersed in water or put in an ultrasonic cleaner. All power hoses should be attached when cleaning, this prevents cleaning fluids from entering the hose or hand piece. A drying cabinet or another separate non-lint cloth needs to be used to dry them.
12. What is the correct procedure for cleaning general instruments?
Manual or mechanically clean instruments in a designated area wearing appropiate PPE. Cleaning minimises staining, corrosion and pitting.

Case Study – The New Engineer
Jeff was just hired by GSI, Inc. to be their Environmental and Safety Coordinator. This is Jeff's first position after completing his engineering degree. He had taken a course in safety engineering as part of his studies and felt confident that he could handle the job.
Management at GSI, Inc. has assured him that they are committed to maintaining a safe workplace. They have never had an individual dedicated to this task full-time. They will implement his recommendations if he can justify them.
As Jeff begins to get familiar with the operations, he spends considerable time on the production floor. He notices workers clean their tools before break with a liquid from an unmarked 55-gallon drum. They also use this liquid to clean residue from their skin. They use paper towels to dry their tools and hands, throw these towels in the trash, and head to the break room for a snack and/or smoke.

Case Study: Paula’s Pain
Paula has worked for Brindle Corporation for 3 years. During this time, she has worked as a machine operator/cell leader in various work cells. Recently, the plant went to mandatory 12-hour shifts and plans to remain on this schedule for several months.
Paula’s present work cell is manufacturing 3-inch diameter exhaust tubes that are made from stainless steel. These tubes get a hole punched in them, a flange welded on, and burrs ground off. The pipe then gets placed into a gage to check that it was made correctly. (The tubes weigh about six pounds.)
Paula has been performing the welding operation. She leans into the machine and loads the part into a fixture then positions the flange. Both pieces are clamped (using hand clamps) into position and the machine is cycled by depressing two palm buttons.
The gaging operation requires placing the finished part into the gage and clamping it (using hand clamps) into place. A pin is depressed to verify the position…

Question 3
You are working on a design team at a small orthopaedic firm. Your team is starting to work on a lower limb
(foot-ankle) prosthesis for individuals who have undergone foot amputation (bone resection at the distal tibia). You remember hearing
about "osseointegration" in an exciting orthopaedic engineering class you attended at Clemson, so you plan to attach the foot
prosthesis using a solid metal rod inserted into the distal tibia. You think stainless steel or titanium alloy might be a useful rod material.
You decide to begin this problem by identifying typical tibial bone anatomy and mechanical behavior (as provided in the tables and
image below). You assume the tibial bone can be modeled as a hollow cylinder of cortical bone, as represented in the image. You
anticipate the length of the rod will be 1/2 the length of the tibia.

will experience the…
