Monoject™ Blood Transfer Set, Tube Holder

Monoject™ Blood Transfer Set, Tube Holder

The Monoject™ Blood Transfer Set, Tube Holder is a single-use accessory designed to support controlled transfer of blood specimens into evacuated blood collection tubes. Used as part of a blood collection tube workflow, the tube holder provides a stable interface for attaching compatible tubes to a transfer set, helping clinicians and laboratory staff maintain consistent handling during specimen transfer. Its design supports common phlebotomy and specimen-processing practices in hospitals, clinics, and laboratory environments where accurate tube filling and secure tube positioning are important.

The holder is intended to be used with an appropriate blood transfer set and evacuated tubes, allowing the tube to be advanced onto the internal needle within the holder to initiate transfer. The form factor is designed for a comfortable grip and predictable tube engagement, helping reduce fumbling during multi-tube collection sequences. By keeping the tube aligned during piercing and filling, the holder supports standard specimen collection protocols and helps minimize unnecessary handling of the tube closure.

Intended Use

This tube holder is used during transfer of a blood specimen into vacuum blood collection tubes. It may be used when transferring from a syringe or other approved collection/transfer method via a compatible transfer set. The holder helps keep the tube steady while the evacuated tube’s stopper is pierced by the transfer needle, allowing vacuum to draw the specimen into the tube until the tube’s intended fill volume is reached.

Key Features

• Secure tube interface: Supports stable seating of evacuated blood collection tubes during transfer.
• Ergonomic handling: Shaped to allow a controlled grip for tube engagement and removal.
• Workflow support: Facilitates sequential filling of multiple tubes when required by the test order.
• Single-use accessory: Intended for one patient encounter to support infection-control practices.
• Compatibility-focused design: Intended to be used with appropriately matched Monoject™ transfer components and standard evacuated tubes as applicable to facility protocols.

Typical Procedure Overview

1. Prepare the specimen transfer setup according to facility policy and manufacturer instructions for the transfer set and tubes.
2. Attach the tube holder to the compatible transfer set connection.
3. Insert an evacuated tube into the holder and advance it until the stopper is pierced and transfer begins.
4. Allow the tube to fill to its intended volume; then remove the tube and gently invert if required for additive mixing.
5. Repeat with additional tubes in the required order of draw per institutional guidelines.
6. Dispose of used components in an approved sharps container and label specimens per laboratory requirements.

Clinical and Safety Considerations

Use only by trained personnel. Follow standard precautions and local infection-control policies. Do not reuse disposable components. Use compatible tubes and transfer devices; mismatched components can affect tube seating, transfer performance, or safety. Inspect packaging and the holder prior to use; do not use if damaged, contaminated, or compromised. Because this holder is part of a blood collection tube process, adherence to specimen handling requirements—such as correct fill volume, gentle mixing for additive tubes, and proper labeling—is essential for sample integrity.

Product Summary

The Monoject™ Blood Transfer Set, Tube Holder is a practical accessory for transferring blood into evacuated collection tubes, supporting secure tube engagement, controlled handling, and efficient multi-tube workflows. When used with compatible transfer components and institutional best practices, it helps streamline specimen transfer while supporting safe, consistent blood collection tube handling.
