DHX Series Animal Ventilator

Product Introduction
The DHX Series Animal Ventilator is a laboratory biological function testing device designed to provide controlled respiratory support for experimental animals that cannot breathe spontaneously due to anesthesia or thoracotomy.
This animal ventilator uses a stepper motor-driven, volume-controlled positive-pressure ventilation system. A microcomputer automatically controls the delivery of air into the respiratory tract according to preset respiratory frequency and tidal volume, helping expand the lungs and maintain gas exchange during biological function experiments.
Using ambient air as the gas source, the DHX Series does not require a high-pressure gas supply. Tidal volume can be precisely adjusted and displayed in real time, with an adjustment accuracy of 1 mL. Respiratory parameters can also be changed during operation, and the newly set values take effect after pressing the start/stop button.

Performance Features
• Volume-Controlled Positive-Pressure Ventilation: Delivers a preset volume of air to the respiratory tract.
• Stepper Motor Drive: Provides stable and precise mechanical ventilation.
• Microcomputer Control: Automatically controls respiratory frequency and tidal volume.
• Adjustable Tidal Volume: Available ranges of 1–50 mL, 1–150 mL and 1–300 mL.
• Precise Volume Adjustment: Tidal volume adjustment resolution reaches 1 mL.
• Real-Time Display: Displays the current tidal volume during operation.
• Adjustable Respiratory Rate: 1–199 breaths/min.
• Multiple I:E Ratios: 1:1, 1:2, 1:3 and 2:1.
• No High-Pressure Gas Required: Uses air as the gas source for convenient laboratory operation.
• Parameter Adjustment During Operation: Respiratory frequency and other working parameters can be changed as required.
• Power-Off Setting Retention: Retains the current operating settings after power interruption.
• Wide Animal Compatibility: Suitable for various laboratory animals from rodents to larger experimental animals.

Working Principle
The DHX Series Animal Ventilator operates as a positive-pressure, volume-controlled ventilator. A stepper motor drives the ventilation mechanism while the microcomputer controls the preset tidal volume, respiratory frequency and inspiratory/expiratory ratio.
During ventilation, air is delivered into the animal's airway at the programmed tidal volume and frequency, causing lung expansion and supporting gas exchange. The operator can adjust the respiratory parameters according to the experimental requirements.
The system uses ambient air rather than a high-pressure gas source, making it convenient for laboratory animal respiratory support during anesthesia or open-chest experiments.
