Understanding the Real Principle Behind Its Suction Power
We occasionally receive questions from customers who place the Sonmol Choking Rescue Device Heimlich Device on a hard flat surface—such as a table—and notice that the suction seems weak. This sometimes leads to confusion or the impression that the device is not working properly.
In fact, this reaction is very common, and the explanation is simple: a flat table does not simulate the human mouth or throat.
Here’s why 👇
🧠 1. Suction Requires an Airtight Seal
For the device to generate strong negative pressure (suction), it must form a tight seal around the mouth.
- A human mouth is soft, curved, and flexible, allowing the device to fit naturally.
- When the seal is tight, almost no air escapes—meaning the vacuum can build up effectively.
🛑 2. A Hard Table Cannot Create This Seal
When the device is pressed against a flat table:
- The surface is too large, too flat, and cannot deform.
- Air leaks easily around the edges.
- The suction cannot build up inside the chamber.
This makes the device appear weak, but it’s actually the surface that causes the reduced pressure, not the device.
In short: Tables don’t behave like human mouths, so the suction cannot be correctly demonstrated on them.
🧪 3. Why a Tube or Simulated Throat Works Perfectly
When we test the device using a tube to imitate the throat:
- The shape is curved,
- The material is softer,
- The contact area is smaller and realistic,
- And the seal becomes tight—just like a real emergency situation.
This allows the pressure inside the device to rise properly, producing the full suction that removes airway obstructions.
✔️ 4. What This Means for Real-Life Use
The Sonmol Choking Rescue Device is designed specifically for human anatomy.
So while a test on a table will not work, the device performs exactly as intended when used on:
- A real airway
- A proper mannequin
- A curved or soft training tube
This ensures the device is reliable, effective, and safe in actual choking emergencies.
❤️ Our Commitment
At Sonmol, we understand that customers want proof of reliability.
We hope this explanation clarifies the physics behind suction and shows why table tests give misleading results.
