clincal reachers laboratory layout
When first discussing the prospects of a clinical laboratory build or redesign with clinical laboratory leaders, invariably among the primary concerns expressed is whether and to what degree flexibility can be afforded to the laboratory’s operations and workflow. Steady changes in instrumentation and science (eg, implementation of new assays) puts pressure on existing physical and operational structures, often resulting in inopportune changes to the layout and organization of the clinical laboratory. Therefore, when first approaching a new laboratory design, enabling Lean principles and workflow efficiency are the prime driving goals. In modern clinical laboratories, flexibility is vital for growth.

1 range

This standard stipulates the directive requirements of space, workbench, storage cabinet, ventilation facilities and lighting in clinical laboratory design.

This standard applies to the design of clinical laboratories.

3 design requirements

3.1 space

Space planning is the most important part of laboratory design. Proper laboratory space is the basis to ensure the quality of laboratory testing and staff safety. Lack of space is a hidden danger in laboratory and affects the quality of laboratory work.

Number of 3.1.1

3.1.1.1 rationalized space

The rational allocation of space is determined according to the need of placing equipment. At the same time, the size of laboratory space should be determined from the perspective of development, so as to accommodate new instruments and equipment in a long time to ensure the efficient and safe completion of clinical work.

3.1.1.2 spatial allocation principle

The general principle of space allocation is to make the staff feel comfortable without waste, taking into account the number of staff, analysis methods and instrument size and other factors.

3.1.2 quality

3.1.2.1 workspace

The size of the workspace should ensure that the largest number of workers work at the same time. Effective space should be divided into clean area (office, rest room, study room), buffer area (storage area, supply area), pollution area (work area, washing area, specimen storage area). The working area should include the area occupied by the staff and the space to move around. Workspace and walking space should be converted to floor space.

3.1.2.2 storage and supply areas

The size and location of the storage area and the supply area have an important impact on the normal operation and safety of the laboratory. The storage area includes bench, elevated, refrigerated and frozen areas.

3.1.3 management

Space management is controlled by its quantity and quality.

Channel management is part of spatial management. In terms of access control, some preparatory areas should be set up, such as access to laboratory personnel and visitors, to receive specimens. The specimen can be transported by staff, automatic transmission, wind power system or other automation system. Laboratory design should also take into account the presence of internal communication systems and alarms to notify or alert (such as disasters, fire alarms, sample arrivals, or other parts of the laboratory for assistance).

3.1.4 extension

3.1.4.1 expansion plan

The laboratory should be designed for outward expansion or mobility so as to meet the needs of laboratory development.

3.1.4.2 air transport system and computer network

Air transport systems and computer networks are used for the exchange of specimens and information within laboratories and between laboratories and departments of hospitals, respectively. Clinical laboratories generally use 10.2 cm air transport tubes to transfer specimens from the collection area to the laboratory.

Laboratories and hospitals can exchange information through computer networks, and the output of data should be fast, sufficient and flexible.

3.1.5 regulations and safety

Laboratory design should strictly comply with the requirements of laws and regulations. It is the architect's responsibility to put forward the requirements of the relevant laws and regulations.

3.1.6 basic principles

Description of 3.1.6.1 space plan

There should be a staff member with laboratory experience and an architect throughout the space program. During the planning phase, managers, planners and architects should discuss the issue repeatedly and prepare a plan that explains the rationality of the space. The list illustrates the use of each space and the interrelation of different spaces.

3.1.6.2 spatial evaluation

Before making the space allocation plan, we should make a comprehensive analysis of the factors such as the number of instruments and equipment, staff, workload, experimental methods and so on.

After careful analysis of various factors, the requirements of the spatial standard were assessed and the net and gross area of the area was calculated. The area of special function determines its distribution space according to its function and activity.

Net area and gross area of 3.1.6.3

The actual working space of the laboratory is the net area of the space. Net area is an effective functional part of the laboratory design. Additional area refers to the mechanical, electrical, pump and infrastructure of the laboratory. The net area of a region is calculated by dividing the total area by 1.35 (74%) to 1.55 (64%).

3.1.6.4 instrument list

An important part of spatial design is to list all the instruments contained in each laboratory area. The length, width, weight, power and ampere of each instrument must be specified, and an instrument manual should be prepared. The manufacturer's manufacturer's instructions on the size, volume and power consumption of the various instruments need to be bound into a book for future reference. The space needed to calculate the length and width should also be taken into account when the instrument needs to be repaired. There should be space on the side and back of the instrument to facilitate work and maintenance. The size of the power needed should be calculated according to the voltage and ampere number, and the cooling device should be set according to the heat output. List the required list and make a list of spatial allocation and functions.

3.1.6.5 laboratory arrangement (layout)

Design laboratory is an independent and specific process. However, two issues should be considered, namely, principles and flexibility.

Transshipment of 3.1.6.5.1 samples and flow of personnel

In the allocation of laboratory areas, staff and patients should be considered first.
