Macintosh Laryngoscope – 4 Blades, Battery Handle, and Transparent Case

The Macintosh Laryngoscope from Peak Surgicals (SKU: PS-DS-00100) is a four-blade Macintosh curved laryngoscope diagnostic set in German stainless steel, supplied as a complete ready-to-use system comprising four Macintosh curved blades in sizes 1, 2, 3, and 4, one Battery Handle, and a Transparent Case for organised blade and handle storage, available in satin, dull, and mirror surface finishes. The Transparent Case is the defining feature that distinguishes this set from the other Macintosh laryngoscope sets available from Peak Surgicals — it provides a rigid, see-through storage container in which the Battery Handle and all four blades are stored in their designated positions, allowing immediate visual confirmation that the complete set is present before the case is opened in the anaesthesia or emergency bay, and protecting the instruments from contamination, physical damage, and blade-to-blade contact during storage and transport between clinical areas. The set is used by anaesthetists, emergency physicians, critical care physicians, and airway management teams in operating theatres, emergency departments, intensive care units, and procedure rooms for orotracheal intubation across the adult and paediatric patient range using Macintosh curved blade indirect vallecula technique, and is particularly suited for clinical areas, resuscitation trolleys, and simulation centres where a self-contained, clearly identifiable laryngoscope system with all components visible in a single case is a procurement or equipment management priority.

Transparent Case: Instrument Organisation, Visibility, and Readiness Confirmation

The Transparent Case included with the Macintosh Laryngoscope (PS-DS-00100) is the primary operational advantage of this set over the other Macintosh laryngoscope sets available from Peak Surgicals. In acute care settings — emergency departments, intensive care units, anaesthetic rooms, and resuscitation bays — laryngoscope sets are stored on equipment trolleys and crash carts that may be accessed by multiple clinical staff across multiple shifts. A transparent case allows any clinical staff member to confirm at a glance, without opening the case, that the Battery Handle and all four Macintosh blades in sizes 1, 2, 3, and 4 are present in their positions before the set is needed — missing components are identified during equipment checks rather than at the moment of intubation. This visual readiness confirmation is not possible with the carton box packaging of the other laryngoscope sets in the Peak Surgicals range. The transparent case also provides physical protection for the blades during storage — the blades are retained in their designated slots, preventing the blade-to-blade contact and handle-to-blade impact that can damage the LED light source contacts or the blade flange geometry of laryngoscopes stored loose in a tray or drawer. The case's rigidity protects the instruments from the mechanical loads applied by items stacked on top of it on equipment trolleys. Transparent laryngoscope cases are the standard storage format recommended by the Difficult Airway Society and most hospital anaesthesia equipment guidelines for laryngoscope sets on anaesthesia machines and emergency airway trolleys.

Four Macintosh Blade Sizes and Battery Handle for Complete Adult and Paediatric Coverage

The four Macintosh blades in the Macintosh Laryngoscope set cover sizes 1, 2, 3, and 4 — the standard Macintosh size range for paediatric and adult intubation from approximately 2 years through large adult. The Macintosh blade's curved profile and tongue-displacing flange achieve glottic exposure through indirect epiglottis elevation — the blade tip is placed in the vallecula between the tongue base and the epiglottis, and upward traction on the handle at 45 degrees applies tension to the hyoepiglottic ligament, drawing the epiglottis anteriorly without the blade tip contacting the laryngeal surface directly. Size 1 covers children from approximately 2 to 4 years, size 2 paediatric patients from 4 to 12 years and small adults, size 3 the large majority of standard adult intubations, and size 4 large adults and patients with anterior laryngeal anatomy or a long oropharyngeal distance. The Battery Handle uses the standard ISO hook-and-bar blade attachment fitting, compatible with Macintosh and Miller blades of the same fitting standard from any manufacturer, and its LED light source illuminates the glottis through the blade's LED contact circuit when the blade is raised to the 90-degree operating position, with the circuit deactivated in the flat storage position to conserve battery life. German stainless steel blade construction ensures autoclave compatibility and dimensional stability across repeated sterilization cycles.

German Stainless Steel, Finish Options, and Sterilization

The four Macintosh blades are manufactured from German stainless steel — selected for corrosion resistance, surface hardness, and mechanical integrity through repeated steam autoclave sterilization. The three finish options — satin, dull, and mirror — address the operating theatre lighting conditions under which the laryngoscope is used. The satin and dull finishes have a non-reflective surface that reduces specular glare from the blade flange and the light source lens under theatre overhead lighting and surgical headlights, which is clinically important because glare from the blade surface in the direct line of sight to the glottis reduces contrast and impairs vocal cord visualisation in some lighting conditions. The mirror finish provides the highest surface smoothness and corrosion resistance and is the standard choice for instruments where appearance and easy inspection are priorities, such as display sets and departmental inventory instruments. All three finishes are compatible with steam autoclave sterilization and standard instrument disinfection protocols. The Transparent Case itself is cleaned and disinfected with surface disinfectant between uses — it is not designed for autoclave processing — and the blades are removed from the case, individually cleaned and autoclaved, and returned to their case slots after the sterilization cycle.

CE Mark, ISO 13485, and FDA Certification

The Macintosh Laryngoscope is manufactured under CE Mark, ISO 13485, and FDA compliant quality standards. ISO 13485 certification confirms Peak Surgicals operates a documented quality management system covering design control, German stainless steel material traceability, blade dimensional tolerancing, LED light source qualification, hook-and-bar attachment mechanism reliability, and post-market surveillance for active diagnostic instruments. CE Mark confirms conformity with EU MDR requirements for active non-implantable medical devices — laryngoscopes carry an electrical light source and are classified as active devices requiring conformity assessment under the active device pathway. FDA compliance supports procurement for US hospitals, anaesthesia departments, emergency departments, intensive care units, and simulation centres. The Class I classification, combined with CE, ISO 13485, and FDA documentation, satisfies the regulatory documentation requirements of hospital equipment committees and procurement departments in all primary markets served by Peak Surgicals.

Frequently Asked Questions

How does this set differ from the other Macintosh laryngoscope sets available from Peak Surgicals?
Peak Surgicals offers four Macintosh-type laryngoscope sets at different price points and configurations. The Macintosh Laryngoscope (PS-DS-00100, $52.80) contains 4 blades (sizes 1–4) + Battery Handle + Transparent Case in German stainless steel — the only set in the range with a transparent case for visual component confirmation. The Mac Laryngoscope Set (PS-OT-0983, $49.50) contains 4 blades (sizes 1–4) without specifying a case, available in both Stainless Steel and Fiber Optic configurations — the fiber optic option provides superior blade-tip illumination not available in PS-DS-00100. The Mac Laryngoscope Set With 5 Blades (PS-40006AA, $38.50) contains 5 blades (sizes 0–4) + Battery Handle in German stainless steel with carton box packaging — the only set covering Macintosh size 0 for infants from 6 months. The Mac and Miller Laryngoscope Set (PS-OT-0981, $77.00) contains 10 blades covering both Macintosh and Miller blade types for departments requiring both curved and straight blade techniques. The Macintosh Laryngoscope (PS-DS-00100) is the best choice for departments prioritising a self-contained, visually inspectable set in a dedicated transparent case.

What is the clinical value of the Transparent Case for emergency and intensive care settings?
In emergency departments, intensive care units, and operating theatres, laryngoscope sets are stored on crash carts, airway trolleys, and anaesthesia machines that are checked at the beginning of each shift or each day by nursing staff or anaesthetic technicians. A transparent case allows the checking staff member to confirm at a glance that the Battery Handle and all four Macintosh blades are present in their designated slots without opening the case and individually counting the components — this is the daily equipment check standard for laryngoscope sets recommended by the Difficult Airway Society and most hospital airway equipment guidelines. If a blade is missing or has been removed for autoclaving and not returned, the gap in the transparent case is immediately visible. With carton box packaging, missing components are only discovered by opening the box and counting — a step that is more frequently skipped during rapid shift handovers and high-workload clinical periods. The transparent case also prevents the blade-to-blade mechanical contact that damages LED light source contacts when laryngoscope components are stored loose in a tray.

What blade sizes are included and which patient age groups do they cover?
The four Macintosh blades cover sizes 1 through 4. Macintosh size 1 is used for children from approximately 2 to 4 years of age, where the oropharyngeal dimensions are large enough for the Macintosh curved blade technique to be used reliably. Size 2 covers children from approximately 4 to 12 years and small adults, and is also used for adult patients with small interincisor distance or limited oral aperture where a size 3 blade cannot be introduced without dental contact. Size 3 is the standard blade for the majority of routine adult orotracheal intubations in patients of normal body habitus — it reaches the vallecula at the correct insertion depth and produces adequate hyoepiglottic ligament tension for reliable indirect epiglottis elevation. Size 4 is used for tall adults, obese patients with a large tongue, patients with a long neck and correspondingly long oral-to-glottis distance, and patients with anterior laryngeal anatomy where a size 3 blade does not provide sufficient vallecula depth. For neonates and infants under 2 years or approximately 12kg, the Macintosh blade is not the preferred technique — Miller straight blades or the Miller series from the Mac and Miller Laryngoscope Set are more appropriate for this age group.

Is the Battery Handle in this set compatible with Miller blades?
The Battery Handle in the Macintosh Laryngoscope set uses the standard ISO hook-and-bar fitting, which is the international standard connector for conventional direct laryngoscope blades and handles from all major manufacturers. Miller straight blades that use the same ISO hook-and-bar fitting are compatible with this Battery Handle. If the department has existing Miller blades from other sources, they can be attached to and powered by the Battery Handle from this set, and the four Macintosh blades in this set can be used on any other ISO-compatible standard laryngoscope handle in the hospital inventory. This cross-compatibility makes the Macintosh Laryngoscope set a flexible equipment investment — the Battery Handle is not proprietary and does not lock the department into a single blade manufacturer for future blade procurement or replacement.

What certifications does this set carry?
The Macintosh Laryngoscope carries CE Mark, ISO 13485, and FDA compliance certification. CE Mark confirms the set meets EU MDR requirements for active non-implantable medical devices — laryngoscopes are active devices because they contain an integral LED electrical light source. ISO 13485 certification confirms Peak Surgicals maintains a quality management system covering German stainless steel sourcing, blade dimensional tolerancing, LED source qualification, and hook-and-bar attachment reliability for active diagnostic instruments. FDA compliance supports procurement for US hospitals, anaesthesia departments, emergency departments, ICUs, and simulation centres. The Class I classification, CE Declaration of Conformity, and ISO 13485 certificate can be requested from Peak Surgicals to support institutional vendor qualification and equipment committee review processes.
