Transcript Protecting Hospitals & OT from Air Borne Diseases

Protecting Hospital OT & Clean Rooms From Air Borne Infections
introduction

•
Al-med equipments started it operation
in 2003 as service and sales provider
in Hospital medical equipments. Soon
it associated with installation of many
higher end medical
Within two years of service, it
incorporated additional service of
installation of medical gas pipeline.
During installation and commission of
Medical gas Pipe Line, our team of
engineers could practically interact
with various doctors and Health
Experts , who in long run help us to
develop a strong foundation and
opportunity to study various design
aspects of Operation Theatres.
With the in-depth study and survey
database, our organization realized
the concern of the micro-biologist and
surgeons.
* Business Profile
• In the last 3 finanancial year, AL-MED
EQUIPMENTS we have rebuilt our infrastructure
and dedicated itself to the cause of reducing
infection of all types through perfect design of
Operation Theatres.
• Armed with trained designers and full fledged
manufacturing unit, we incorporated the NABH
guidelines in letter and spirit , strictly covering
major aspects. In fact, AL_MED EQUIPMENTS
was the first to understand the disadvantages of
conventional Air Handling Unit with Duct.
Concept total solution for OT under
one single roof
• Today, an ISO
9001:2008 certified
manufacturing SSI
unit and with most of
OT equipment
manufactured by us
as marked CE .
• We provide total OT
Solution from Flooring
to ceiling.

OT Equipments
A reliable partner
• We undertake turnkey
project of Operation
Theatres in which
designing,
commissioning and
after completion
provide class
validation of
Operation Theatres
from Third Party
* * Our initiative
• To overcome the challenge of infection
due to Air Conditioning .
NABH Guidelines also says that
“WindowSplit A/c should not be used in any
type of Operational Theatre.”
Air condition is one of the major sources of
infection in Operation Theatre
•

We implemented our basic model of ductless Laminar
Air Flow and Ductless Positive Pressure System with
Air conditions with following key features which is as
per standard norms and guidelines of NABH.
which is user friendly, and easy to install.
which as per OT size
which has a system which ensure that HEPA perform
effectively for maximum life span
AIR CONDITION IS NOT FIXED WITH Laminar Air
Flow WHICH IN CONVENTIONAL DESIGN CAUSES
PATIENT TO SHIVER
Second concern was the unawareness of
the demerits of Centralized Duct System.
• Due to present of moisture as
result of condensation, long
ducts are ideal breeding
ground of Bacteria .Moreover,
it is difficult to access, inspect
and clean or sanitize the
internal surfaces of the duct.
Due to any reason, if the flow
of air is not maintained in duct
– there is vigorous bacterial
and fungus growth. Moreover,
moisture which accumulates in
the duct due to condensation
adds ideal environment for
multiple growth of fungus and
bacteria.
Thumb-rule to be followed as per
guidelines
• NABH guidelines say “AHU Blower (Fan)
should be operational round the clock
,may be without temperature control” to
reduce bacterial or fungus growth .
• But practically it is very difficult and found,
not followed in many hospitals, keeping
AHU ON to maintain Air Flow in the duct in
that condition.
Ductless Positive Pressure System
In AL-Med designed
CONCEPT OF DUCTLESS SYSTEM ELIMINATES
THE CHANCES OF DISEASES LIKE SURGICAL SITE
INFECTION (SSI).
Our system is not centralized and dedicated for
particular -single OT.
Thus ,unlike the convention Ductless system.
Our designed system is NOT A SOURCE OF
CROSS CONTAMINATION OR CROSS INFECTION.
Third concern was to give effective and safe
solution to control airborne infection inside OT by
replacing conventional fumigation methods.
•
•
•
Hospital in our country used chemical based OT Fumigation system which not only
take longer time but also the OT need to be kept idle or sealed till the poisonous
effect comes down to permissible level. Immediately , after one surgery – the OT take
minimum interval of 5 to 8 hours – till it is ready for the next surgery. .
Chemical residue after fumigation and VOC is serious health concern for OT
occupants. Surgeon and OT staff who are exposed to toxic residue and
carcinogenic ,thus the occupants suffer from various irritation in Eyes, Skin , Nasal
and respiratory tracks.
We took the initiative to apply the ozone dosing in post operative OT and could
practically demonstrate the merits of Ozone .Not only Ozone reduces VOC , but after
some time converts into oxygen. The costing of ozone dosing was cost effective,
and after an hour application in the OT, the level of air borne microbes and aerosols
in air got drastically reduced and gave excellent test result. The reason behind the
success story is because of the properties of Ozone. Ozone (nascent Oxygen)
interferes with the metabolism of bacterial cells and blocking the operation of the
enzymatic control system. Ozone destroy viruses by diffusing through the protein
coat into nucleic acid coat, resulting in damage of viral RNA .At higher concentration,
ozone destroy capsid or exterior protein cell by oxidation.
In a nutshell, Ozone is effective in all types of bacteria , fungus , virus and molds and
clears in few seconds and sanitization can be achieved in one hour in a standard Modular
OT.
• After successful practical trials , we
introduced O 3 MAGIC DISINFECTANT
.Today ,many critical operation
Superspeciality OT are using O3 Magic
Disinfectant to sanitize the OT.
* Three Key Achievement:
•
When we introduced the concept of Ductless Laminar
Air Flow System and Ductless Positive Pressure
system with Air Conditional system, we faced series of
questions as we went against very popular Centralized
System. We successfully maintain both the Velocity of
Air at HEPA Level (90 t0 100 FPM) at Laminar Air
Flow and 30 Air cycle per Hour from Positive Pressure
System .Also , we have ensure that Air Flow patterns
does not interfere and disturb air patterns and fulfill
the basic requirement of NABH guidelines for Air
Handling.
Both Ductless LAF and PPS are
independent in function.
Surgeons are now having full confidence on
the performance of the Ductless System,
• Now, when many critical operations like Joint
replacement surgery is being conducted with
absolute success and approved by many
Laparoscopic Surgeon,
• Approval itself at the initial stage is an achievement,
for us as the concept of Ductless is getting popular.
To reduce Air Infection ( Post Operative) with zero hazardous
residue effect
•
•
•
Thirdly , with the introduction of O3 Gen , we have
achieved minimum time of OT remaining ideal , thus
many critical operation can conducted in the same
day. Any hospital generally plan the operation
schedule or routine based on the level of infection.
Even few years back, tumor or infection borne
operation are schedule in the later part of the day and
normally , less infection are scheduled in the earlier
part of the day.
Now with the combination of ductless system and O3
magic , the convention mentioned above practice need
not be followed.
* Three Key Challenges while implementing
the Product and how they were overcome.

1)
The biggest and the most challenging aspect was to maintain both the speed of 90 to
110 FPM .from HEPA and to simultaneously maintain Air Cycle of 30 Air Cycles per
Hour (ACH).
LAMIAR AIR FLOW was designed in such a fashion that it will only be responsible
for maintaining the air tent and velocity of filter Air from HEPA.
To develop the Positive Pressure ,the PPS design take care of 30 Air cycle per Hour
norms.
This would have been impossible for a common system of Duct. Since, the machine
performs separately; it is simple and easy to achieve both the criteria of NABH
guideline.
Through our Positive Pressure Dampers we could implement the fresh air cycle (5
ACH of fresh air in 30 ACH ie approx 16%).Control dozing of Ozone inside Positive
Pressure System help to control VOC and microbiological count inside the Positive
Pressure. Ozone gas produced by ozone producing UV Light which give 0.21 ppm
dosing for 5 minutes in every 30 minutes.
This on line dosing is not continuous and preset timing based, so there is absolutely
no difficulties for OT occupants
* Three Key Challenges while implementing the
Product and how they were overcome.
(cont..)
• 2) Achievement of Air Conditioning
Tonnage.
•
The cooling of OT (21+/- 3 ○ C) is
maintained / achieved with 3 Tonns as
compare.to
•
Ducted AHU where , minimum 8 to 12
tonnage is required .
•
* Three Key Challenges while implementing the
Product and how they were overcome.
(Cont..)
• Our system need not be kept “ON” for 24
hours.The system is put “ON” ,one hours
before the schedule operation , thus
saving lot of Electricity.
•
Latest achievement is that we have concluded and
synchronized the noise level to 70 db which is very
closed to the norms.
