What are the specifications and precautions for conventional hospital laboratory decoration design?

Equipped with dehydrators, paraffin embedding machines, microtomes, staining machines and other equipment and facilities corresponding to the pathological examination projects carried out. The new laboratory department is designed and decorated in accordance with the CNAS-CL02 standards and relevant laws and regulations for the new laboratory requirements. The overall layout takes into account the connection of various laboratories and the needs of internal operations, emphasizing the optimization of the layout to improve the efficiency of the overall work. and quality. At the same time, strict regional and process controls have been implemented for laboratory biosafety, which fully reflects the laboratory department’s quality policy of “quality, pragmatism, efficiency, and improvement”.

The laboratory has been divided into standardized areas according to the specimen processing process, which are: specimen pre-processing area, experimental area, buffer area, clean area and office area. Each area is divided according to its own requirements. corresponding functional areas. The decoration design introduces the concept of assembly line operations. Various instruments and personnel positions are arranged in accordance with the order of specimen processing procedures, thereby reducing the time for specimen and data transfer and improving overall work efficiency. Moreover, by bringing together the laboratories that were originally scattered on various floors of the hospital, the personnel in each laboratory can support each other and work collaboratively, making full use of the human resources of the laboratory department. The new laboratory department has also set up a reading area to facilitate employees to access various professional materials, which can not only provide support for research and professional judgment, but also facilitate employees to learn new technologies and new knowledge. This fully reflects the hospital and department leaders’ regard for employees. of humanistic care.

? 1. Key points in the design and planning of the medical laboratory department

1. The clinical laboratory should be located near the entrance of the laboratory; clinical examinations serving outpatient services should have specimen collection rooms and Waiting area.

2. The biochemical laboratory should be equipped with a fume hood, instrument room (cabinet), medicine chamber (cabinet), and anti-vibration sky platform; there should also be facilities for storing valuable drugs and highly toxic drugs.

3. The bacterial laboratory should be located at the end of the laboratory department. When a sterile inoculation room is set up, there should be a front room; if a culture room is set up, the right side of the operating table should be lit; a transfer window should be set up between the inoculation room, the bacterial testing room and the culture medium room.

4. The inspection room should be equipped with washing facilities, and special washing facilities should be set up for bacterial inspection; each inspection room should be equipped with at least one washing pool without manual switch.

2. Blood bank

1. It should be close to the operating department and should not be adjacent to rooms that generate radiation.

2. It is composed of blood storage, blood matching, cleaning, disinfection and other rooms; for larger ones, the blood storage and blood matching rooms should be separated into separate rooms, and a front room should be set up between them and the aisle. Blood banks located in laboratory departments should have appropriate sanitary isolation.

3. Blood banks with self-collected blood should add a blood donation room, a perfusion room, a blood cell separation room, and a blood donor lounge, and should form a separate area.

3. Indoor layout

In order to facilitate work and instrument maintenance, in large laboratories, large and major instruments and equipment are placed in the middle of the house. This not only facilitates heat dissipation when the instruments are working , fault repair, and easy to clean and hygienic. Specimen processing, distribution, adding samples and some small experiments that do not require hands-on operation are performed on the workbench next to the wall. This arrangement is also very convenient for the flow of staff and the transfer of samples. Due to limited space in small laboratories, the workbench is usually set up against the wall.

4. Environment selection

In order to facilitate patients and clinical departments to send specimens, the new laboratory department chose the second floor of the building. The emergency department and charging office are downstairs, and the upstairs The 12th floor gathers all inpatient clinical departments except the Department of Infectious Diseases. It is very reasonable and convenient to conduct various emergency tests during the middle and evening shifts (there is also an outpatient laboratory for the day shift) and daily tests.

5. Room allocation

Modern inspection instruments and equipment are developing in the direction of large-scale and automated assembly lines. To this end, we have opened up the original space thinking, from the perspective of development, and adopted In order to establish a large-scale laboratory, the biochemistry and immunology laboratory were merged into one room in the south-facing room.

6. Water source design

All laboratories have installed cleaning pools (independent dedicated hand-washing pools) and pollution pools (for washing and dyeing), and the sewers are directly connected to the hospital sewage. processing system.

The wash basin is controlled by a foot pedal, which not only meets the laboratory hygiene requirements, but is also relatively durable. The pollution pool is used to wash experimental dirt, and a deep pool is made to prevent splashing.

7. Power supply design

The experimental instruments and auxiliary electrical equipment should be positioned in advance, the power sockets should be assembled, and they should be wired separately from the lighting power supply so as not to interfere with each other. Important instruments and equipment are equipped with uninterruptible power supply (UPS power supply) and special grounding wires, and consideration has been given to reserving many instruments and temporary power sockets that may be purchased for future laboratory development.

8. Lighting design

The lighting equipment in the laboratory is mainly fluorescent lamps, which are installed semi-invisibly in the polished ceiling parallel to the work surface; incandescent lamps are used in the corridors, and different lighting sources are used. The combination creates a comfortable and aesthetic visual enjoyment in the laboratory. Eye-catching light boxes are installed at the entrance of the laboratory department, the emergency room window, and the duty room to facilitate the public's search at night. To effectively protect staff and avoid specimen contamination. The bacteria room is equipped with four 30W ultraviolet lamps according to relevant requirements. As commonly used disinfection equipment, it is also semi-invisible in the ceiling.
