Rotating Broome-Type Rodent Restraint Device

Precision Handling for Safe and Efficient Rodent Procedures

The Broome-Type Rodent Restraint Device is a precision-engineered system designed to provide stable, safe, and low-stress immobilization of laboratory rodents during veterinary and research procedures. Developed using advanced CAD engineering and manufactured through high-resolution 3D printing with biodegradable PLA+, the device combines modern design with practical laboratory functionality.

Its ergonomic cylindrical structure ensures secure positioning while maintaining airflow, visibility, and procedural access, making it particularly suitable for procedures requiring tail vein access, injections, and physiological monitoring.

Designed for research laboratories, veterinary clinics, and biomedical institutions, the device supports efficient workflows while promoting animal welfare and operator safety.

Key Features

270° Rotational Handling

The restraint system allows up to 270° rotation when used as a standalone device, providing flexible positioning and optimal access to the animal during procedures such as tail vein injections.

Optional Stabilization Base with Controlled Rotation

The device can be installed on a dedicated mounting base for full immobilization. When mounted, the system allows controlled rotation up to 180° (90° left and 90° right), ensuring stable positioning while maintaining convenient access.

Sliding TPU Entry Door

A durable TPU 95 sliding door enables quick and safe placement of the animal while maintaining secure restraint. The integrated tail exit opening ensures proper positioning during procedures.

Protective Cylindrical Restraint Design

The cylindrical body provides stable immobilization and prevents excessive movement, reducing the risk of injury and improving handler safety.

Conical Movable Piston with Head Support

A movable conical plunger secures the animal’s head while maintaining a dedicated ventilation channel for continuous airflow.

Adjustable Headpiece System

The rotational locking adjustment mechanism allows precise positioning for rodents of different sizes, ensuring optimal restraint and procedural accuracy.

Optimized Ventilation

Perimeter airflow openings ensure adequate ventilation, helping maintain animal comfort during restraint.

Stable Anti-Slip Base Option

A TPU 95A anti-slip base provides stability on laboratory surfaces, while an optional neodymium magnet mounting system allows secure placement on metal workstations.

Key Benefits for Researchers

Improved Procedural Efficiency

Stable restraint and controlled rotation allow easier access during injections, catheterization, and sampling procedures.

Reduced Animal Stress

Ergonomic positioning and proper ventilation help minimize discomfort during handling and restraint.

Enhanced Operator Safety

The cylindrical design prevents excessive movement and protects handlers from bites or scratches.

Flexible Laboratory Use

The device can be used standalone or mounted on a stabilization base, depending on procedure requirements.

Durable and Sustainable Construction

Manufactured with high-strength biodegradable PLA+, combining durability with environmentally responsible materials.

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.
