Classification of various characteristics of products used as medical devices as minimum performance requirements during traumatic surgery.
3.3.2
High performance
Classification of various characteristics of products used as medical devices as stricter performance requirements during traumatic surgery.
Note: Examples of surgical procedures that shall be considered to improve the performance level are those that are excessively exposed to fluids, mechanical stress, or longer surgical procedures.
3.4
Product
Surgical gowns, surgical drapes and clean air suits.
Note: For surgical kits, each surgical gown or drape is considered a product. 3.5
Sterile field
The area covered by the sterile surgical drape for aseptic procedures.
Note: The sterile area can be located, such as the instrument table.
4 Performance requirements
The product must comply with the YY/T 0506 series of standards. When tested according to this standard, it shall meet the requirements specified in Table 1, Table 2 or Table 3. See Appendix A for detailed information on the
corresponding test method and its application.
If the medical device is intended to be used in a sterile area, then the surgical drape and instrument drape shall meet the requirements of Table 2.
Note 1: YY/T 0506.1 gives manufacturers, processors and products, information to be provided and general requirements for production, processing and testing. Note 2: Performance requirements are as specified in accordance with product area and performance level. However, the performance requirements of some features will apply to all performance levels of medical devices and product areas of medical devices.
Appendix A
(Normative)
Test method
A.1 General
Unless otherwise specified, the atmosphere for pre-conditioning, conditioning and testing shall be carried out in accordance with GB/T 6529. Before the test, the sample shall be state-conditioned without restrictions.
A.2 Cleanliness-microbial evaluation test method
It shall follow the test method given in YY/T 0506.7 to evaluate the cleanliness- microbial.
A.3 Test method for the evaluation of cleanliness-particulate matter
It shall follow the test method given in YY/T 0506.4 to estimate the cleanliness- particulate matter.
Note: YY/T 0506.4 allows the test to be carried out in a laminar flow hood. If the instruments required for the test are placed in the hood, it is necessary to confirm the occurrence of laminar flow.
In order to estimate the cleanliness-particulate matter, the following changes apply to this document.
a) It shall calculate the particle count in the range of 3 ??m ~ 25 ??m.
Note: Particles in this specification range are considered to carry microbial. b) Add the particulate matter counts obtained from the first three time points 30s, 60s and 90s according to the following formula to calculate the
particulate matter (PM):
PM = C30 + C60 + C90
The test results shall be reported in terms of the index of particulate matter (IPM), which is usually expressed in logarithmic values for
particulate matter: IPM = log10 PM.
Note: This test procedure cannot distinguish between particulate matter and lint in this period of time, so these two parts are included.
A.4 Test method for evaluation of lint
Appendix B
(Informative)
Optional test method
B.1 Test method for evaluation of liquid control
If the manufacturer claims that the liquid control of the product depends on its absorption to achieve its purpose, it is recommended to evaluate it according to GB/T 24218.11 and make the following modifications:
a) Distilled water or deionized water is used as the test liquid;
b) It shall use the overflow percentage (w) to calculate the liquid retention percentage as follows:
Percentage of fluid retention = 1 - w
The percentage of liquid retention is the amount of liquid absorbed by the material.
Note: Other tests to evaluate absorption such as GB/T 24218.6 or GB/T 24218.12. B.2 Test method for evaluation of breathability
It is recommended to evaluate the breathability of the product according to the test of GB/T 5453.
The applicable test parameters are:
a) Test area: 20 cm2;
b) Pressure drop: 100 Pa.
Note: Breathability is an important aspect of evaluating the comfort of surgical gowns and surgical drapes (see also Appendix A of YY/T 0506.1), which is a contradiction between protective performance.
B.3 Laser resistance
It may use the test method as specified in the YY/T 0855 series of standards to give the primary ignition level, penetration level, secondary ignition level of the surgical drapes, so that the doctor can take appropriate protective measures. B.4 Drapability
It may follow GB/T 23329 to evaluate the drapability of the surgical gowns and
