System Overview
RWD Surgical & Anesthesia Solutions for Small Animal Research: There is growing demand for anesthesia equipment designed for small laboratory animals. RWD designs and manufactures complete anesthesia systems and accessories for the smallest preclinical research subjects. These systems are designed to deliver highly effective anesthesia with depth modulation. RWD systems are also designed with user safety as a priority. The system includes excellent waste gas scavenging to protect users from the negative effects of short-term exposure to anesthetic gases.
These complete anesthesia solutions are perfect for new labs or if you are in the process of upgrading your current system
Complete Anesthesia & Respiration Systems
Multi-function Anesthesia Solutions

The experimental system is equipped with a gas recovery system to provide a safe experimental environment to maximize the protection of the operator. You have the ability to replace the different types of anesthesia machines and masks to meet the needs of the animal experiments, such as cerebral ischemia and myocardial ischemia model, osteoporosis model, tail vein injection, abdominal aorta blood sampling, heart blood sampling, ventricular injection, tissue / organ removal and other animal surgery experiments.
Stereotaxic Anesthesia Solutions

By changing the different types of stereotaxic instruments and adaptors, you can meet the needs of different animal experiments, such as the neurological disease models (Parkinson’s, Alzheimer’s disease, craniocerebral injury, spinal cord injury, etc.), brain drug injection, cannula implantation (long term repeated administration), physiology experiments (such as nerve stimulation, signal recording, wireless telemetry, etc.), microdialysis experiments (probe implantation and short-term dialysis), and other experiments.
Combination Solutions of Ventilator to Anesthesia System

This solution offers a combination of anesthesia machines and ventilators. While keeping the animal under anesthesia, the ventilator provides a certain volume (tidal volume) of oxygen and respiratory rate to support the normal breathing of animals. It can meet the requirements of long surgeries or surgeries on animals suffering from certain diseases (such as cardiovascular and cerebrovascular diseases, hypertension, cerebral infarction, thrombosis), and is suitable for mice, rats, rabbits, cats, and other animals within 5KG.

Two kinds of vaporizers


Three Dosing Methods



Installation Type

RWD Active Gas Evacuation Unit
The gas evacuation apparatus was designed to safely and actively remove waste gas associated with everyday inhalation anesthesia. The waste gas from cone masks, concentric tubing masks, and stereotaxic frame nosecone masks can be pulled through an activated charcoal canister so that the air can be re-circulated into the room. The evacuation apparatus will accommodate waste gas supply from up to 5 masks. The newest design has been upgraded to offer a wider range of exhaust flow, low noise, and exquisite exterior design.

Benefits
New design makes it easy to carry.
Powerful capture allows evacuation of waste gas supply from 1 to 5 masks.
Power: 100-240V, 50/60Hz.
The velocity of “pull” or “draw” can be adjusted depending on the stations (masks).
The velocity of “pull” or “draw” can be adjusted depending on the stations (masks).
Digital scale to view the weight of canister directly from the LED display.
Significant evacuation effectiveness to replace the traditional exhaust fan.
Small size 215mm (W)*215mm (D)*170mm (H).
Two level overweight alarm: 990g and 1010g.
R415 ,R419 & 420 Intelligent Animal Ventilator

ThermoStar Homeothermic Monitoring System
During the process of animal surgery or acute anesthetized animal experiments, maintaining animal body temperature is very important for the accuracy and reliability of results. This is a great way to prevent the mortality of the animal. To fulfill this need, RWD launched a new homeothermic monitoring system, the “Thermostar”, which is a closed loop temperature monitoring/controlling system for rodents. The system includes the control unit, 1 flexible rectal probe, 1 heating pad. The system can also be equipped with 2 pads and 2 probes for 2 animals. The control unit includes a 4.3-inch color LCD touchscreen that allows users to clearly view the subject’s real-time core body temperature, set the target temperature, view the heating state, and set audible alarms for subject’s core body temperature abnormality. A separate control circuit for heating pad and rectal probe ensures stability and safety of the system.
