Flexible Tip Conventional Laryngoscope blade Mac#4 (133mm)

Clinical Application

This curved Macintosh blade size 4 is intended for direct laryngoscopy and orotracheal intubation in adult patients where extra length and reach are required. The flexible distal tip permits controlled adjustment of the blade tip position during laryngoscopy to optimize the view of the glottis, facilitate passage of endotracheal tubes, and reduce the need for excessive lifting force—useful in routine airway management as well as cases with limited cervical mobility or challenging anatomy.

Design & Configuration

The blade uses the conventional Macintosh curvature to seat in the vallecula and achieve indirect elevation of the epiglottis. The incorporated flexible-tip feature allows subtle angulation at the distal segment without changing the overall Mac geometry, enabling the operator to fine-tune tip placement and glottic exposure while maintaining familiar handling and technique. The size 4 length (133 mm) provides additional reach for larger adult patients.
