Mouse Restraint Device – 3D Printed (PLA+)

Reliable Restraint for Precise and Low-Stress Small Animal Procedures

The Mouse Restraint Device is a precision-engineered system designed to provide secure, stable, and humane immobilization of laboratory mice during non-anesthetized procedures. Developed using advanced CAD design and manufactured through high-resolution 3D printing with durable biodegradable PLA+, the device combines accuracy, functionality, and environmental responsibility.

Optimized for non-invasive and minimally invasive applications, it enables researchers to perform procedures such as indirect blood pressure measurement, rectal temperature monitoring, blood sampling, and physiological observation without the need for anesthesia. Its ergonomic design ensures proper positioning of the animal while maintaining comfort, airflow, and continuous monitoring.

Key Features

Sliding Piston with Integrated Nose Cone

A front-positioned sliding piston with anatomically shaped nose cone ensures secure and comfortable head positioning, while an integrated air channel allows continuous and unobstructed breathing.

Adjustable Internal Chamber

The internal piston is horizontally adjustable, allowing precise adaptation to mice of different sizes. A rotating screw-lock mechanism secures the selected position, ensuring stability during procedures.

Rear Entry Door with Locking System

A secure rear door allows easy placement and removal of the animal and includes a locking latch for safe closure, along with a dedicated tail exit opening.

Integrated Access Ports

The rear section includes a tail access opening for procedures such as tail-cuff placement or sampling, as well as a dedicated port for rectal thermometer insertion.

Transparent Observation Window

A plexiglass viewing panel enables continuous visual monitoring of the animal’s respiration and condition throughout the procedure.

Optimized Ventilation Design

Multiple ventilation openings distributed along the body ensure consistent airflow, reducing stress and enhancing animal welfare.

Optional Magnetic Base

Available with embedded neodymium magnets for secure positioning on metallic laboratory surfaces or instrument platforms.

Durable, Eco-Friendly Construction

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

Modular & Replaceable Components

All moving elements (piston, door, screw) are modular and replaceable, supporting easy maintenance, cleaning, and long-term laboratory use.

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.
