staff, equipment, to prevent the spread of infective agents between patients and
clinical staff in the surgical procedure and other invasive examination process.
This part does not include surgical masks, surgical gloves, packaging materials,
shoes, caps, surgical incision films. GB 7543 gives the requirements for medical
gloves, while ISO 11607 1) gives requirements for packaging materials.
This part does not include flammability requirements for products used in laser
surgery. ISO 11810 2) gives the test methods for flammability and penetration
resistance during laser irradiation, as well as the corresponding classification
system. Other basic requirements for surgical gowns and surgical drapes will
be included in YY/T 0506.2.

Clean operation
Operation performed on uninfected, non-invasive tissue and does not enter
the respiratory tract, digestive tract, or urethra.
2.17.2
Infection-prone operation
The operation which may cause infection due to even small contamination
as determined by the nature of the operation or the patient’s condition.
2.17.3

2.18
Permeability to air
The ability of air to penetrate the fabric.
3 Information to be provided by manufacturers and
processors
3.1 The following information shall be provided:
a) If the manufacturer anticipates a device to be reused, there shall be
disposal information for its reuse, including methods for cleaning,
disinfection, packaging, re-sterilization (if applicable), the number of
reuses, any restrictions on reuse;
b) If the equipment is sterilized before supply, it needs providing the
sterilization method;
c) If the manufacturer divides the critical area and non-critical area of the
Table 3 -- Characteristics of clean air suits to be evaluated

Note: Clean air suits are rarely used at present, but they are available on the market, so they are
included in this standard.
4 Manufacturing and processing requirements
4.1 The manufacturer and the processor shall be able to provide proof that the
product meets the requirements listed in this series of standards and is suitable
for single-use and repeated use.
Note: It is recommended to use a quality system that complies with the requirements
of YY/T 0287.
4.2 It shall use confirmed manufacturing and processing procedures.
4.2.1 The manufacturing and processing specifications of the product shall be
designed and confirmed, including appearance and sanitary cleanliness.
4.2.2 Confirmation shall include all steps of manufacturing and processing.
4.2.3 The frequency of re-confirmation in the confirmation process shall be
determined. Any changes in manufacturing or processing shall be re-evaluated
on whether it will have a substantial impact on the product.
4.2.4 It shall identify, monitor, record key production or processing parameters;
the form and frequency of routine monitoring shall be documented.
4.2.5 The results of confirmation and routine monitoring shall be recorded and
retained.
Note: The confirmation and monitoring process is preferably a biological test, chemical
test and/or physical test.
4.3 During manufacturing and processing, it shall maintain the control of
decontamination and disinfection procedures and traceability of sterilization.
4.4 It shall be demonstrated that the properties of the material have been
maintained during manufacturing and processing.
Appendix A
(Informative)
Comfort
A.1 General
The concept of comfort is based on several different aspects, such as
physiological comfort, ease of exercise, or other factors that affect personal
satisfaction with the product
Fabric and design, especially hand washing clothes and operating room clothes,
shall minimize the physical stress generated during the work.
The climatic comfort of clothing depends on thermal insulation, permeability to
air, water vapor permeability and drapeability.
The tactile comfort of clothes mainly depends on the stretchability, drapeability
and surface structure of the fabric; it also depends on the quality, specifications,
sewing and manufacturing of the clothes.
Other performances such as sounding, softness, skin irritation, etc., which are
difficult to measure, it should be evaluated based on trial use or practical
experience of the product.
A.2 Surgical gowns and clean air suits
The overall comfort of surgical gowns and clean air suits is affected by many
factors, including design, sewing, permeability to air, quality, surface thickness,
electrostatic properties, color, light reflection, odor, skin sensitization.
Other important parameters that can affect comfort are underwear, health and
physiological conditions, workload, mental stress, operating room temperature,
relative humidity, ventilation and other environmental conditions.
Comfort also varies from person to person or is affected by one or a
combination of the above factors.
A.3 Surgical drapes
The surgical drapes shall be soft, so that it can cover the patient closely; it is
conducive to the placement and operation of the instrument, and to the
coverage of other related instruments.
The surgical drapes shall have reasonable physiological comfort and support
the patient's physical condition.
Appendix C
(Informative)
Prevention of infection in operating room
Most postoperative infections in the surgical area are caused during the
operation, because the microorganisms have the opportunity to reach the open
wound at this time. Microbial sources either come from outside (i.e. from
medical personnel, inanimate objects or other patients), or from inside (i.e. from
patients). In aseptic surgery (that is, surgery in sterile tissue without entering
cavity organs), the skin of clinical staff and patients in the operating room is the
most important source of microorganisms. In susceptible surgery (such as
orthopedic and intravascular implant surgery), the microbial flora common in
the skin is the main source of infection at the surgical area.
The route of infection is contact or airborne. In the latter case, diffused human
dander is often a carrier of infective agents. The various barriers involved in this
part are used to reduce infection at the surgical area.
When a healthy person walks, it will diffuse 5000 bacteria-containing dander
into the air every minute. The size of these particles is 5 µm ~ 60 µm. Each
dander is estimated to carry an average of about 5 aerobic and anaerobic
bacteria. These airborne particles may be directly deposited on the wound
surface, or first deposited on the equipment or other equipment that is in contact
with the wound surface, then indirectly contaminate the wound surface through
them. Fabrics with a gap greater than 80 µm, such as traditional cotton fabrics,
cannot basically prevent the spread of dander.
Clean air suits can be used to reduce the spread of bacteria-carrying dander
from the operator to the air in the operating room. Clean air suits should be
used together with surgical gowns, but not a substitute for surgical gowns.
Surgical gowns are used to prevent direct contact transmission and reverse
transmission of infective agents from the surgical staff to the surgical wound.
Surgical gowns can only be able to prevent the spread of dander into the
operating room air if it is made of suitable materials and used with ultra-clean
air systems.
The surgical drape is used to provide microbially clean area around the wound
surface. It can be used to prevent the spread of the patient's skin flora to the
wound if it is closely held to the wound and is fixed to the skin. The surgical
drape and/or collection equipment are also used to control the spread of
contaminated body fluids in the wound area.
