Walk-through Metal Detectors

The complete range of EIA walk-through metal detectors is available. These products are approved and used in the most sensitive areas of government and airports throughout Europe and the United States.

We have over 10 years experience in the installation and application of metal detectors to provide the highest level of security available anywhere in the world.

In a hospital situation where management are in a position to control uniform a very high sensitivity can be employed to detect the smallest objects and in a situation where patients wear their own clothes, airport style security settings offer a substantial level of protection for patients and staff.

An example of the need to be careful about metal detecion in hospitals is given here.

Hand-held Metal Detectors PD140

Hand-held metal detectors are normally used to support walk-through metal detectors to find smaller objects.

Objects can be detected either on the person or in packages or discarded items.

The most sensitive hand-held metal detector PD140S has been successfully used to detect metal objects within the bodies of small children without using Xrays and extracts from the relavent report are provided below.

Metal objects near the surface of an adult body would also be detected dependant upon size of the object.

Successful use of metal detector in locating metallic foreign bodies ingested by children

Introduction: Foreign body ingestion constitues a common problem in pediatric emergency medicine. The most commonly ingested foreign bodies are coins. Past recommendation included radiographs of the entire gastrointestinal tract in all children with suspected foreign bodies. Coins that become impacted in the esophagus may cause complications.

Presented is a method for diagnosing ingestion of metal bodies with a metal detector. The purpose of this study was to determine the accuracy of the hand metal detector PD140S in locating coins in a model simulating coin ingestion in children.

Methods: The distance between the anterior chest wall and the esophagus was measured by ultrasound in a group of 20 children aged from 1 to 7 years. The largest distance measured was used as the measure to place the coin on the investigator's forearm. In 41 cases the coin was taped to one arm only, in 35 cases to both arms and in 24 cases there was no coin. In the investigation we used a range of coins. A positive scan was defined as a positive visual indication on the metal detector.

Results: The largest distance between the anterior chest wall and the esophagus was 5.8 cm. We confirmed 111 coins with the metal detector. In 89 cases we did not confirm the existence of a coin. The result was accurate in every case. The accuracy of the the metal detector was 100% in our study.

Conclusion: With this study we confirmed the diagnostic significance of the metal detector in identifying metal foreign bodies through human tissues. The results of this study have indicated that the hand metal detector PD140S is 100% reliable in assessing certain coins at a distance corresponding to that between the anterior chest wall and the esophagus in children aged 7 or less. The advantage of using the metal detector as compared to x-ray is in the duration of the investigation, its economy and safety. The advantage is also evident in diagnosing aluminiun foreign bodies.
