HEIMLICH VALVE - LARGE The Heimlich valve - large is a semi-rigid, one-way flutter valve designed for thoracic drainage in veterinary applications, particularly in medium to large-sized animals. It allows air (and possibly small amounts of fluid) to exit the pleural cavity during exhalation and prevents backflow during inhalation, supporting lung re-expansion and aiding in the management of pneumothorax or pleural effusion.

Main Benefits

- Semi-rigid cylindrical design suitable for use in large animals - Facilitates passive evacuation of air (and minor fluids) from the chest - Prevents inward airflow, maintaining negative pressure - Allows greater mobility compared to traditional underwater seal systems

Construction

- Semi-rigid plastic cylinder containing a one-way rubber flutter valve - Includes connectors compatible with chest tubes with a funnel hub or tubes with an internal diameter of approximately 8.5 mm to 12 mm - Includes a male Luer adapter for connection to compatible chest tubes

Instructions for Use

- Connect the valve to the distal end of the chest drainage tube sized appropriately for the patient - Ensure the valve is oriented to allow air to exit and prevent entry into the pleural cavity - Use under veterinary supervision; a qualified veterinarian should determine usage details based on species, body weight, and clinical condition

Package Size

- One unit (one valve per package)

Note

- Valve operation depends on sufficient expiratory effort; it may be less effective in small animals or those with respiratory weakness - Frequent monitoring is recommended to detect potential blockage due to secretions or valve malfunction
