ERKA Perfect Aneroid Sphygmomanometer and Stethoscope Analysis Report

Device Identification

The images show one manual mechanical blood pressure monitor (sphygmomanometer) set and one stethoscope. The products are medical devices suitable for professional use, employed for medical diagnosis and examination purposes. The set consists of a manometer, a bulb (pump), a cuff (armband), and a stethoscope.

Brand and Model

Sphygmomanometer: A detailed examination of the manometer dial in the images clearly identifies the brand of the product as ERKA. and its model as PERFECT Aneroid. The dial features the inscriptions “Made in Germany Since 1889” and “THE ORIGINAL”.

Stethoscope: The stethoscope included in the set is observed to be of the ERKA. brand, compatible with the sphygmomanometer. The ERKA logo and the inscription “Made in Germany” are clearly legible on the stethoscope’s metal body and diaphragm. However, since the specific model name of the stethoscope (e.g., Finesse, Sensitive) could not be definitively identified as text in the images, only the brand could be determined.

Originality

Both products (sphygmomanometer and stethoscope) exhibit extremely high craftsmanship quality, detailed laser-printed labels, and consistent brand logos. The chrome-plated brass body of the manometer, the print quality on the dial, the stitching details on the cuff, and the mention of the original manufacturing location “Bad Tölz” on the label all confirm that the products are 100% original German-made ERKA brand items.

Areas of Use

These devices are used by medical doctors, nurses, paramedics, and healthcare students for monitoring vital signs. Specifically:

• Manually measuring patients’ arterial blood pressure,
• Listening to heart and lung sounds (auscultation),
• Suitable for pulse checks and general physical examination procedures.

Quantity Information

A total of 2 main items are visible in the images:

• 1 ERKA Perfect Aneroid Sphygmomanometer with Manometer and Cuff (Integrated set)
• 1 ERKA Stethoscope

Overall Condition and State

Upon visual inspection, the overall condition of the products can be described as excellent. Even if it is a used item, it has been extremely well-maintained, with no corrosion or rusting visible on its metal components. The cuff fabric retains its vibrancy, and no yellowing or cracking is noticeable on the stethoscope’s tubing.

Physical Deformations

No significant physical deformations were detected on the devices:

• Manometer: The glass is intact, the dial is clean and scratch-free. There are no dents or deep scratches on the metal body.
• Cuff: The fabric texture is intact, with no unravelling or tearing. The Velcro parts appear sound.
• Stethoscope: The eartips (oliva) are in place. The tube surface is smooth. There are no impact marks on the metal diaphragm ring.

Mechanical and Electronic Components

The device operates entirely on mechanical principles; it has no electronic components. Mechanical component details are as follows:

• Screw Valve: The air release valve beneath the manometer appears robust and functional.
• Connections: No disconnections or looseness are visible at the points where the tubes connect to the manometer and bulb.
• Clip Mechanism: The metal hook/clip mechanism on the cuff, which secures the cuff, is in sound and shiny condition.

Accessories

The original box or carrying case for the products is not visible in the images. However, the functional parts of the device are complete:

• Original dark green, double-tube cuff.
• Dark green rubber bulb (air pump).
• Chrome-plated manometer.

Label Information

The labels and prints on the product contain the following technical information:

• Serial/Ref No (Manometer): 21104990
• Manufacturer Address: D-83646 Bad Tölz (Germany)
• Size Information (Cuff): RANGE: 29-40 cm (Suitable for Adult Arm Circumference)
• Quality Standards: CE mark, indications of conformity to ISO standards.
• Cuff Type: The label structure in the images suggests that the cuff may belong to ERKA’s “Green Cuff” series (Bio-compatible, PVC-free, washable).

Size and Compatibility

The cuff label clearly states “RANGE: 29-40 cm”. This measurement indicates that the product is suitable for standard adults and adults with larger arm structures (also known as Large Adult size). It would be too large for infants or children with very slender arms.

Existing Malfunctions and Risks

No evidence of product malfunction (e.g., broken needle, punctured tubing) is found in the images. The product appears operationally ready for use. The only potential risk that could arise from long-term use is the mechanical manometer losing its calibration accuracy over time or the rubber tubes hardening; however, in their current appearance, the tubes are flexible, and the manometer appears stable at the “0” point.
