Introduction

During the formulation of the standard series of small aperture connectors for medical liquids and gases (see YY/T 0916), it was found that the wrong connection the risk is not limited to the connection to the patient, but also needs to be considered for the entire reservoir system. In addition, monoclonal antibody was also considered Possible incorrect connection between the coagulant reservoir connector and the trocar. However, the apheresis anticoagulant reservoir connection is not completely full the definition of small-foot-aperture connectors, it was decided to develop a separate standard for such connectors to consider Risk of incorrect connection between other devices that can be used on the same patient.

YY/T 1842 "Connectors for Medical Liquid Storage Container Delivery Systems for Medical Devices" is intended to consist of the following parts.

--- Part 1: General requirements and general test methods;

--- Part 3: Gastrointestinal application;

--- Part 6: Neurological applications;

--- Part 7: Connectors for intravascular infusion;

--- Part 8: Application of apheresis citrate anticoagulant.

This document specifies the geometry, materials, and properties of apheresis anticoagulant reservoir connections to enable analysis (and avoidance) of their He is not apheresis to apply the connection between the connectors.

This document only specifies the connector dimensions of the apheresis anticoagulant reservoir connections for single-use tubing instruments and reservoirs.

This item is not a product standard.

1 Scope

This document specifies the dimensions, design and functional characteristics of the connections for apheresis anticoagulant reservoirs.

This document does not specify dimensional or performance requirements for medical devices or accessories using these connectors. These requirements are used in dedicated medical devices or in the annexed standard.

The following are examples of medical devices intended to use the connectors in this document.

---Apheresis separation pipeline and supporting liquid storage container containing citrate anticoagulant;

---Apheresis separation lines may include, but are not limited to, lines used for blood collection, therapy, and plasma collection.

Some apheresis separation kits are manufactured with pre-connected reservoirs containing citrate anticoagulant. These medical devices do not use this Connectors specified in the documentation.

Note. Although not required in the current medical device product standard, manufacturers are encouraged to use the connectors specified in this document for apheresis devices or accessories. medical instruments Product standards may be revised to increase requirements for apheresis anticoagulant reservoir connections.
