Mac Laryngoscope Set With 5 Blades – Macintosh Sizes 0–4 with Battery Handle, German Stainless Steel

The Mac Laryngoscope Set With 5 Blades from Peak Surgicals (SKU: PS-40006AA) is a five-blade Macintosh curved laryngoscope set in German stainless steel comprising five Macintosh curved blades — sizes 0, 1, 2, 3, and 4 — and one Battery Handle, providing the complete Macintosh blade range from infant and small paediatric through standard and large adult for orotracheal intubation across all patient age groups managed with the Macintosh indirect vallecula technique. The set type is listed as a Diagnostic Set with 5 Blades and 1 Battery Handle, available in satin, dull, and mirror surface finishes, reusable, rust-free, and steam-autoclave compatible. It is used by anaesthetists, emergency physicians, critical care physicians, and airway management teams in operating theatres, emergency departments, intensive care units, and paediatric settings for general anaesthesia induction intubation, rapid sequence intubation, and emergency airway management across the full patient size range where Macintosh blade technique is employed. The Mac Laryngoscope Set With 5 Blades carries CE Mark, ISO 13485, and FDA certification and is manufactured from German stainless steel to Class I medical device standards.

Five-Blade Coverage: Macintosh Size 0 Through Size 4 for Infant to Large Adult

The Mac Laryngoscope Set With 5 Blades extends the standard four-blade Macintosh series (sizes 1–4) with the addition of Macintosh size 0 at the lower end of the size range — the size 0 Macintosh blade is the infant and small paediatric blade for patients from approximately 6 months to 2–3 years of age whose oral and oropharyngeal dimensions are too small for the size 1 blade to reach the vallecula at the correct trajectory without contacting the upper teeth or gum ridge and compromising the indirect epiglottis elevation technique. The size 0 blade's shorter length and narrower flange match the reduced oral aperture and oropharyngeal depth of the infant airway, and its curvature is proportioned to the shorter distance from the upper incisors to the vallecula in this age group. Macintosh size 1 covers the age range from approximately 2 to 4 years, size 2 from approximately 4 to 12 years and small adults, size 3 the standard adult population, and size 4 large adults and patients with a long oropharyngeal distance or anterior laryngeal anatomy. Having all five sizes on a single Battery Handle allows immediate blade exchange during a difficult intubation without requiring a second laryngoscope or handle to be opened. The five-blade configuration makes this set particularly suitable for departments managing both paediatric and adult patients — paediatric emergency departments, mixed medical-surgical intensive care units, and general anaesthesia departments covering the full age range from infants to large adults.

Battery Handle and Blade-to-Handle Attachment Mechanism

The Battery Handle included in the Mac Laryngoscope Set With 5 Blades houses the power supply — typically two C-cell or AA batteries depending on the handle size — that drives the LED light source in each blade. The blade attaches to the handle via a standard Welch Allyn-compatible ISO hook-and-bar fitting, in which a hook on the blade heel engages a bar on the handle and the blade is folded to the upright position, completing the electrical circuit between the handle battery contacts and the LED at the blade. This hook-and-bar attachment system is the international standard fitting for laryngoscope blades and handles, meaning the blades in this set are compatible with any ISO-standard battery handle from other manufacturers — the blades can be used on existing hospital-standard handles, and the Battery Handle supplied with this set can accept Macintosh or Miller blades of the same fitting standard from other sources. The fold-flat storage position with the blade horizontal against the handle is the standard non-activated storage configuration used in anaesthesia trays and emergency airway trolleys — the handle-blade assembly occupies minimum tray space in the flat position and is immediately activated by rotating the blade to vertical for the next intubation. The handle's LED circuit activates only when the blade is raised to 90 degrees, conserving battery life between uses.

German Stainless Steel Construction, Surface Finish Options, and Sterilization

The five blades of the Mac Laryngoscope Set With 5 Blades are manufactured from German stainless steel — a high-chromium, low-carbon surgical instrument alloy selected for corrosion resistance, surface hardness, and dimensional stability through repeated steam autoclave sterilization cycles. The blades are available in satin, dull, and mirror surface finishes. The satin and dull finishes reduce specular reflection from the blade surface under operating theatre lighting and surgical headlights — in laryngoscopy, reflection from the blade flange directly in the line of sight to the glottis can reduce contrast and impair visualisation of the vocal cords, making the lower-reflectivity satin finish the standard choice for most anaesthesia and emergency departments. The mirror finish provides the smoothest surface and best corrosion resistance and is preferred for demonstration sets and instruments where appearance is a procurement consideration. All three finishes are compatible with steam autoclave sterilization — the blade is separated from the Battery Handle, cleaned of blood and secretions under running water with a brush following each use, and then processed through the institution's standard stainless steel instrument autoclave cycle. The Battery Handle is cleaned and surface-disinfected separately, as most laryngoscope handles are not designed for full immersion autoclave processing.

CE Mark, ISO 13485, and FDA Certification

The Mac Laryngoscope Set With 5 Blades 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 testing, and post-market surveillance for active diagnostic instruments used in airway management. CE Mark confirms conformity with EU MDR requirements for active non-implantable medical devices — laryngoscopes are classified as active devices due to their integral electrical light source. FDA compliance supports procurement for US hospitals, anaesthesia departments, emergency departments, paediatric units, and intensive care facilities. The Class I instrument classification, combined with CE, ISO 13485, and FDA documentation, satisfies the vendor qualification requirements of hospital procurement departments and equipment committees across the primary markets served by Peak Surgicals.

Frequently Asked Questions

How does this set differ from the Mac Laryngoscope Set (4 blades, PS-OT-0983) and the Mac and Miller Laryngoscope Set (10 blades, PS-OT-0981) also available from Peak Surgicals?
The Mac Laryngoscope Set With 5 Blades (PS-40006AA, $38.50) contains Macintosh sizes 0, 1, 2, 3, and 4 — five curved blades covering infants from approximately 6 months through large adults — plus one Battery Handle, in German stainless steel only. The Mac Laryngoscope Set (PS-OT-0983, $49.50) contains Macintosh sizes 1, 2, 3, and 4 only — four blades, no size 0 — and is available in both Stainless Steel and Fiber Optic configurations. The Mac and Miller Laryngoscope Set (PS-OT-0981, $77.00) contains both Macintosh and Miller blades — ten blades covering both curved and straight blade techniques across the full neonatal-to-adult patient range. The 5-blade set at $38.50 is the lowest-priced option and adds size 0 coverage absent from the 4-blade set, making it the better choice for departments managing patients from infancy through large adulthood using exclusively Macintosh technique. The 4-blade set offers the fiber optic configuration that the 5-blade set does not. The 10-blade set adds the complete Miller straight blade series for departments requiring both blade types.

When is Macintosh size 0 used and how does it differ from size 1?
Macintosh size 0 is the infant Macintosh blade for patients from approximately 6 months to 2–3 years of age. Its shorter overall blade length is matched to the reduced oral-to-glottis distance of the infant — a standard size 1 Macintosh blade in a 12-month-old patient would extend beyond the vallecula into the oesophageal inlet if advanced to its full insertion depth, risking oesophageal stimulation or intubation rather than glottic exposure. The size 0 blade's narrower flange also produces less tongue displacement than size 1 in the infant oral aperture, where excessive lateral force from an oversized flange risks dental or gum ridge injury. Macintosh size 1 is the standard blade for children from approximately 2 to 4 years, where the oral and oropharyngeal dimensions have grown enough to accommodate the larger blade length and flange of the size 1 without overshoot at the vallecula. For neonates under 6 months and premature infants, the Miller straight blade series (sizes 00 and 0) is preferred over the Macintosh curved blade because the infant larynx at this age is too anterior and cephalad and the epiglottis too floppy for reliable indirect vallecula elevation — the Mac and Miller Laryngoscope Set should be used for neonatal airway management.

Are the blades in this set compatible with other manufacturers' laryngoscope handles?
The Macintosh blades in the Mac Laryngoscope Set With 5 Blades use the standard ISO hook-and-bar attachment fitting — the international standard connector used on the large majority of conventional direct laryngoscope handles from all major manufacturers. This means the blades are interchangeable with any ISO-compatible standard laryngoscope handle in the hospital inventory, and the Battery Handle supplied with this set will accept ISO-standard Macintosh or Miller blades from other sources. The hook-and-bar fitting is distinct from the newer proprietary green-spec or anti-shock fittings used on some specialist laryngoscope systems — confirm the handle fitting standard at your institution if replacing or supplementing an existing proprietary system. For new hospital procurement, the Battery Handle and five blades in this set provide a self-contained, complete Macintosh laryngoscope system requiring no additional components.

Why does this 5-blade set cost less than the 4-blade Mac Laryngoscope Set?
The Mac Laryngoscope Set With 5 Blades (PS-40006AA) is priced at $38.50 and includes five Macintosh blades plus a Battery Handle. The Mac Laryngoscope Set (PS-OT-0983) is priced at $49.50 and includes four Macintosh blades without specifying a battery handle in the set contents. The price difference likely reflects the stainless-steel-only configuration of the 5-blade set versus the Stainless Steel and Fiber Optic configuration options available for the 4-blade set — fiber optic blade assembly adds manufacturing cost and the 4-blade set's pricing reflects this option. The 5-blade set at $38.50 is a stainless-steel-only set with a Battery Handle included, making it the most cost-effective entry point for departments equipping new airway management stations or simulation laboratories with complete Macintosh coverage at minimum cost per station.

What certifications does this set carry?
The Mac Laryngoscope Set With 5 Blades carries CE Mark, ISO 13485, and FDA compliance certification. CE Mark confirms conformity with EU MDR requirements for active non-implantable medical devices — laryngoscopes are active devices due to their integral LED light source. ISO 13485 certification confirms Peak Surgicals maintains a quality management system covering German stainless steel sourcing, blade dimensional controls, LED component qualification, and manufacturing process documentation specific to active diagnostic instruments. FDA compliance supports procurement for US hospitals, anaesthesia departments, emergency medicine, paediatric, and intensive care units. The Class I instrument classification and the CE, ISO 13485, and FDA documentation package satisfy the vendor qualification and regulatory documentation requirements of hospital procurement committees in the USA, European Union, South Asia, and Southeast Asia.
