Rat Restraint Device – Broome Type | 3D Printed (PLA+)

Reliable Restraint for Safe and Efficient Laboratory Handling

The Broome-type Rat Restraint Device is a precision-engineered system designed to provide secure, stable, and low-stress immobilization of rodents during laboratory and veterinary procedures. Developed using advanced CAD software and manufactured through high-resolution 3D printing with durable biodegradable PLA+, the device combines accuracy, safety, and sustainability.

Based on the proven Broome-type cylindrical design, the system ensures effective restraint while minimizing the risk of injury to the animal and protecting the operator during handling and procedural workflows.

Key Features

Broome-Type Cylindrical Design

The cylindrical chamber prevents the animal from turning, ensuring effective immobilization while protecting the handler from bites and scratches.

Sliding Entry Door with Locking System

A secure sliding door allows easy placement and removal of the animal, featuring a locking pin mechanism and a dedicated tail exit opening.

Conical Movable Plunger with Head Support

The integrated conical head slot provides stable positioning of the animal’s head, while a ventilation opening ensures continuous airflow during procedures.

Adjustable Interior Length

A rotating screw-lock mechanism allows precise adjustment of the internal length, accommodating both juvenile and adult rats.

Optimized for IV Injection & Blood Sampling

Provides stable positioning for intravenous administration and blood collection without the need for additional sedation.

Support for Physiological Measurements

The tail exit design enables indirect blood pressure monitoring and rectal temperature measurement with ease.

Optimized Ventilation Design

Perimeter ventilation slots ensure consistent airflow, enhancing animal comfort and reducing stress.

Stable Anti-Slip Base

Equipped with TPU 95A anti-slip feet, ensuring secure placement on laboratory benches.

Optional Magnetic Mounting

Available with integrated neodymium magnets for stable positioning on metallic surfaces.

Durable, Eco-Friendly Construction

Manufactured from high-strength biodegradable PLA+, offering durability while reducing environmental impact.

Modular & Replaceable Components

All key moving parts (plunger, door, screws) are modular and replaceable, ensuring long-term usability and easy maintenance.

Advantages

  • Safe and ergonomic animal restraint
  • Enhanced operator protection
  • Suitable for multiple procedures (injections, blood sampling, monitoring)
  • High stability on various working surfaces
  • Environmentally responsible manufacturing
  • Adjustable to accommodate different animal sizes

Rodent Restrainers and Recommended Body Weight Ranges

Each restrainer size corresponds to specific animal body weight ranges in order to ensure proper fit, animal welfare, and procedural accuracy.

  • The above weight ranges are indicative and may vary depending on animal strain, body composition, and specific experimental requirements. In practice, restrainer dimensions often support overlapping body weight ranges.
  • The dimensions of the devices (restrainers, anesthesia masks, etc.) can be customized upon special order according to the customer’s requirements.
