2 목 차 1. Unicel DxH 800 도입 배경 2. Unicel DxH 800 소개

3 1.Unicel DxH 800 도입 배경 1. 기존 사용장비인 SE -9000의 노후화 (2002.11월에 도입)
2. 장비 노후화에 따른 환자 결과의 review rate 증가 3. QC 의 어려움 & QC 소모 증가

4 2. Unicel DxH 800 소개 DxH 800 + DxH 800 단독 Floor Stand a b
So therefore the next generation platform would allow you the option of a stand alone bench top analyzer, [mouse click] or the option of having the analyzer be a floor standing model if you were short on bench space or [mouse click] the ability to connect one or more modules together.

From 3 internal parameters to 29.

6 DxH 800의 New Technologies High Definition Digital Analysis

7 Specimen Processing Module (SPM)
Output Buffer Input Buffer Beacon Status Indicators (상태 창)

8 Cassettes Note that the cassettes have only 5 positions. This is a CLSI guideline for automation and allows for quick processing, rerun and reflex of specimens. All the cassettes have metal pads on the bottom of the cassettes. This allows for magnetic movement of cassettes without accessible moving parts. Up to 20 cassettes can be loaded at one time in the input buffer

9 Input Buffer Sensor 밑으로 cassette을 올려 놓으면 자동으로 검사 시작.
It is important to note that the module will not move the cassette unless the first cassette is loaded in the sensing area. This will be indicated by the green sensor lights lighting up.

10 시약, Waste, Power supply 가 내장.
Floor Stand 시약, Waste, Power supply 가 내장. Here is the floor stand with the doors opened. Note that only 1 drawer at a time can be extended. This shows the 2 diluent boxes (note that they are smaller than previous analyzers). The SPM will automatically switch from 1 diluent box to the other without stopping processing or any action taken from the user. It is important to note the correct box orientation. The cap on the box must face the right of the cabinet, as shown in the picture above.

11 Floor Stand This shows all the reagents with color coded pickup tubing that corresponds to the same color on the reagent boxes.

12 Single Tube Presentation으로 검사 진행
Cap piercing 가능 Microtainer 가능 This shows the single tube presentation. The left side is for standard size hematology tubes. The right side is for microtainer specimens.

13 상태 Icons 1. System Status : 장비 상태 2. Review Result : 환자 결과 확인
3. Daily Checks 4. QC 5. XB / XM 6. Supplies : 시약 및 Waste 7. Event logs This is the System Status Screen. The LH had common icons in the left hand corner. Most user functions are accessed from the top bar (known as Alert status icons). If neutral color, then everything is OK. Yellow or red color indicates that attention is needed.

14 Daily Checks No longer known as startup. The Daily Checks and setup can be accessed by selecting the daily check icon from the Alert Status area.

15 Daily Checks Here is the daily check screen. If Daily Checks fail, Click on the Daily Checks tab from this screen to repeat it. Don’t repeat failed Background counts by selecting Background.

16 Quality Control To view QC select the QC (chart) button on the Alert Status area.

17 Quality Control 최근 Results – 가장 우측편에 보임
The most recent results appear in the far right side of the screen. The previous 3 results then appear to the left of those results.

18 QC가 벗어 났을 경우 If there is a QC “out” alarm, the user must acknowledge the alarm by selecting “Click to Review” or the color indicators will continue in the Alert status area. There is also a check box to exclude the result from calculation. “Click to Review를 눌러 주면 위의 빨간색이 없어짐.

19 QC: Graph View This is the QC graph view. All parameters graphs are shown as thumbnails with the last 10 runs shown. The current parameter selected is shown in an enlarged Levy Jennings chart that shows all runs with the last 10 backlit in blue.

20 QC: 다른 level 볼 때 To view another control file, click the Select Control tab.

21 Supplies : 시약 잔량 Supplies can be viewed by selecting the supply button in the alert status area.

22 Supplies : 시약 및 Waste 상태 표시
Here is the supply list. The color of the reagent “bottles” matches the packaging. Note the 2 diluent bottles. One is backlit and not in use yet. This screen also shows the approximate # of the cycles remaining. To setup low level alerts (in %), click the configure low level button.
