This list is a part of our LIS users. We have constructed many LIS in lots
of laboratories. We are also the first Client Server type LIS maker by
Personal Computer in the world. Therefore, we have handled the LAS construction
not only by the aspect as LAS maker but also as a LIS maker. I would like
to introduce some typical examples and explanations of the kinds of systems
we have constructed. |
|
Slide#2
 |
This is a system that automates Clinical Chemistry Testing at Iwate Medical
University.
|
|
Slide#3
|
This is a system at Showa University, which covers chemistry, immunology,
coagulation, urine chemistry, and hematology. |
|
Slide#4
|
This is a system at Metropolitan Ebara Hospital, which covers chemistry,
immunology, urine chemistry. |
|
Slide#5
|
This is Okazaki municipal hospital?fs middle scale system, which covers
chemistry, urine chemistry and immunology. |
|
Slide#6
 |
This is Iizuka hospital?fs system, which covers chemistry, urine chemistry,
immunology, and Hematology. |
|
Slide#7
 |
This is a system at Kagoshima University, which covers chemistry, urine
chemistry, immunology, and coagulation. |
|
Slide#8
 |
Some users of our CLINILOG system were introduced.
As the result of many constructions in "Open" concept like these,
we enabled the connection of many analyzers as shown on this screen.
The analyzers of A&T, DIAYATORON, TOSHIBA, HITACHI , and JEOL can be
connected as an analyzer for chemistry and serology. |
|
Slide#9
 |
For immunology, each model of IRC, TOSOH and ABBOTT is acceptable to connect
to our LAS. DIC's Urine analyzer is acceptable for Urinalysis. The coagulation
analyzer of IRC or Sysmex is acceptable. For Hematology, we can connect
Coulter's Gen*S, Omron's slide maker and Sysmex's or Bayer's Island LAS.
The fact that even competitive analyzers of A&T have been connected
to our LAS proves our LAS is open. I have shown you many laboratory systems.
You should have noticed the use of the analyzers of various makers. We
have constructed many LAS with "Open" posture. |
|
Slide#10
 |
Because of this process, we found various problems.
One of problems is the structure of connection between LIS, STS and analyzers.
We experienced three types of the connection. One; Our LIS and our STS.
Two; Our LIS and Other company's STS. Three; other company's LIS and Our
STS. When we tried the second type, Our LIS and Other company's STS, the
most popular connection structure was the Triangle Structure. |
|
Slide#11
 |
That is to say, almost all of the other company's STS needed the Triangle
Structure, which is the worst structure. In almost every case of this type,
STS maker and LIS maker will not cooperate with relative ease, because
each companies cost will change terribly with the assignment of work.
We believe, the customer must have the Duplicated LIS Structure while STS
and LIS makers are different. STS maker has to take the responsibility
of mini-LIS for LAS.
Of course, we trust that our system?fs structure is the best and the most
advanced structure.
|
|
Slide#12
 |
The next problem is analyzer's suitability for LAS.
We think, almost all analyzers in the market are unfit for the construction
of LAS, because sometimes it takes samples inside and won't send them back
to STS. Sometimes it dips its probe in a sample over and over again or
keeps samples and won't release them quickly.
Analyzers like those are not suited for LAS. The reason is those analyzers
needs dedicated samples aliquoted for the analyzer and for the rerun.
For the user of those analyzers, the dead-volume reduction, the daughter
sample number reduction, the aliquot workload reduction, and the rerun
sample volume reduction are very difficult. The LAS that increases the
collection volume from patient is straying from the correct way, even if
the level of automation is very high. |
|
Slide#13
 |
Undoubtedly, the analyzer which needs a large size mechanism and expensive
cost for the connection to STS is unsuitable for LAS. |
|
Slide#14
 |
On the screen, you see one of the planned solutions to approach the ideal
analyzer. This idea was imagined by Prof. Sasaki 10 years ago. When we
approached the open and high performance LAS, we thought that this idea
would be completely suitable for LAS.
Outside Sampling, Once Dip Sampling, Fast catch & release of sample,
Holding diluted sample for initial-run and rerun.
If all analyzers have these specifications, the LAS design becomes easier.
But, to our regret, there are only two models of this analyzer in the present
market. Our 502 and JEOL's Bio-Majesty. The NCCLS work standardization,
the outside sampling is included in the direction. We think NCCLS must
include "Fast catch & release of sample" also. |
|
Slide#15
 |
The next problem is the difficulty of stepwise construction. The stepwise
construction is very important for users. It is also the successful way
for finding easy ways to plan the budget, constructing safely and certainly,
and avoiding being out dated. But, actually, the stepwise construction
is enormously difficult. |
|
Slide#16
 |
It is only realized by the system that has sufficient design concepts for
a stepwise construction. For example, when a user designs LAS with triangle
structure and the LIS maker was not identical with STS maker, a stepwise
construction is enormously difficult, even if the analyzers are suitable
for LAS.
It is almost impossible to reconstruct the marked portions on the screen
without stopping routine analysis. |
|
Slide#17
 |
I'll show you an actual example of the stepwise construction by our LAS,
CLINILOG system. We have completed some additional reconstruction without
stopping routine analysis in several laboratories. The reason of success
was our CLINILOG had careful design concept for stepwise construction.
If the design of LIS is careful to realize stepwise construction like our
LIS, CLINILAN system, there is only some registration of parameters required
after the mechanical connection. |
|
Slide#18
 |
This is an actual example at Kagoshima University. A&T 502 and TOSOH
AIA-21 were connected one year after the initial construction without stopping
routine work. |
|
Slide#19
 |
This is another actual example at Komagome Metropolitan Hospital. One TOSOH
HbA1c machine, one IRC-Coagrex-700, Two A&T-GA03U and two TOSOH-AIA-21
were connected without stopping routine half year later after the initial
construction. |
|
Slide#20
 |
Now, I have shown you some problems noticed in our experience to construct
the high performance LAS. I can say those problems are at three checkpoints
for the construction of high performance LAS.
No.1 is "Open Architecture". User must hold the casting vote
for the selection of analyzers. A closed system supplied by an individual
maker would not or could not be the best combined system. At any time in
history, I don't know of any maker who could supply all of the best machines
for all fields, chemistry, hematology, immunology, coagulation, etc. And
perhaps, in the future too. I believe that the goal of NCCLS standardization
is the Open Architecture too.
No.2 is the stepwise construction and the partial reconstruction. This
checkpoint is very important to construct LAS safely and certainly and
to avoid being out dated.
No.3 is "Thorough Integration" of analyzers and STS lines, etc.
By thorough integration, User could reduce the number of analyzers, the
number of operators, the space and the cost of laboratories, and finally
the reduction of the patient blood collection volume must be completed. |
|
Slide#21
 |
"Open Architecture", "Stepwise Construction", "Thorough
Integration" By these design concepts, we packaged a system as the
best combination system.
I'm showing it to you on the screen. All on one line. De-cap Unit, On-line
and Off-line Aliquot Unit, Coagulation analyzer, Immunology analyzer, Special
chemistry analyzer, Chemistry analyzer and Hematology analyzer are all
connected to one line STS.
Of course, the several customization and the stepwise reconstruction are
acceptable. We trust that this system has very high performance capabilities. |
