Suction Catheter for Use in the Respiratory Tract
1 Scope
This Standard specifies the requirements for plastics-made suction catheter for use in
the respiratory tract.
Special suction catheters, for example, multi-lumen suction catheters without terminal
orifices, are not included in the scope of this Standard.
Suction catheters with curved heads (for example, catheter) are not
considered as special suction catheters, and, are therefore included in the cope of this
Standard.
2 Normative References
Through the reference in this Standard, clauses of the following documents become
clauses of this Standard. In terms of references with a specific date, all the subsequent
modification sheets (excluding the corrected content) or the revised editions are not
applicable to this Standard. However, all parties that reach an agreement in
accordance with this Standard are encouraged to explore the possibility of adopting
the latest version of these documents. In terms of references without a specific date,
the latest version is applicable to this Standard.

3 Terms and Definitions
The following terms and definitions are applicable to this document.
3.1 Adaptor
Adaptor refers to a special joint for the establishment of functional continuity among
different or unmatched parts.
3.2 Connector
Connector refers to an adapting piece for the connection of two or more parts.
3.3 Eye
Eye refers to side hole near the patient end of a catheter.
3.4 Machine End
Machine end refers to an end of catheter used to connect to the vacuum source.
3.5 Patient End
Patient end refers to an end of catheter used to intubate patient.
3.6 Residual Vacuum
Residual vacuum refers to the negative pressure at the patient end of catheter when
vacuum control device is in the release position.
3.7 Shaft
Shaft refers to the main part of catheter with consistent outer diameter.
3.8 Suction Catheter
Suction catheter refers to a flexible shaft (3.7) with a machine end (3.4) and a patient
end (3.5) used in the respiratory tract for the suction of tracheobronchial secretions.
3.9 Terminal Orifice
Terminal orifice the central opening of the patient end of suction catheter.
3.10 Tip
Tip refers to end tail end of the patient end of suction catheter.
3.11 Vacuum Control Device
Vacuum control device refers to a device for controlling air flow and aspirate at or near
the machine end of catheter.
endotracheal tubes, tracheotomy tubes and corresponding connectors. Conduct visual
inspection.
5.4 The external surface of shaft should be bright and clean, which can reduce surface
friction.
5.5 The materials used to manufacture suction catheter should make the wall thickness
of suction catheter as thin as possible. Meanwhile, maintain its resistance to flattening
and kinking.
5.6 Under normal use conditions, suction catheter should be sufficient to resist the
erosion of anesthesia steam and gas.
6 Design
6.1 Lumen
The inner diameter of lumen in any part between the machine end and the eye closest
to the machine end shall be not less than the inner diameter of the shaft at the eye.
6.2 Patient End
6.2.1 Suction catheter whose tip cannot be observed during use, or, suction catheter
which is used for suction system with a vacuum pressure of more than 40 cmH2O (3.92
kPa) shall have terminal orifice. In addition, there shall be a side orifice within a
distance of at least 2 cm from the terminal orifice.
6.2.2 In terms of suction catheter whose tip can be observed during use, or, suction
catheter which is used for suction system with a vacuum pressure of 0 cmH2O (0 kPa)
~ 40 cmH2O (3.92 kPa), side orifice is not required.
6.2.3 The aperture of terminal orifice shall be not less than 90% of inner diameter of
catheter.
6.2.4 The tip and side orifice shall be smooth. Conduct visual inspection.
6.2.5 The side orifice should not trigger kinking or flattening of suction catheter during
the process of using.
6.2.6 The axis of the patient end may form an included angle with the long axis of the
shaft (see -type catheter tip in Figure 1).
6.3 Machine End
6.3.1 The machine end of suction catheter shall be permanently connected to the shaft
and satisfy the requirements in 7.1.
(or X-ray radiopaque marking) shall be not less than 0.10.
7.3 Vacuum Control Device
When suction catheter with permanently connected vacuum control device is tested in
accordance with Appendix B, the residual vacuum shall not exceed 0.33 kPa (3.4
cmH2O).
8 Requirements for Aseptically Supplied Suction
Catheter
8.1 Sterility Assurance
Aseptically supplied suction catheter with designated “STERILE” shall comply with the
requirements of 4.1 in YY/T 0615.1-2007.
8.2 Packaging of Aseptically Supplied Suction Catheter
