Any healthcare facility relying on the functioning of medical devices needs to be aware of key factors related to medical leak testing to ensure safety for patients. The following are five vital factors to be aware of regarding leak testing to devise an effective testing regime for medical devices.

1. One essential function is to create a barrier between different gas or fluid substances.

Medical devices serve a wide variety of purposes, but generally, a common purpose regarding many different types of device is to create barriers between fluids and/or gases. Medical device barriers are essential for the proper functioning of the device. Any leak could result in fluids or gases because deliver to or extracted from the wrong location of the body.

2. Leak testing is essential when it comes to medical device integrity

Malfunctions regarding medical device barriers are extremely dangerous because they can risk patient lives. Medical devices need to offer the utmost in precision when working with fluids and gases in the body, and any inaccuracies can have drastic consequences.

3. The most common leak detection methods are what's known as "dry-air" test methods.

When a dry air method is used for medical leak testing, components of the medical device are pressurized. This will create a situation where changes in the pressure of device compartments being tested will clearly show that a leak is present. 

4. Sample testing is often not sufficient for leak testing for medical devices.

Leak testing methods for non-medical devices might involve simply testing a sample area and using sample testing to judge the integrity of the entire device.

However, sample testing usually will not suffice with medical devices. Leaks are such a severe safety problem with medical devices that tests usually need to involve the entire product. This will ensure critical safety measures are taken that will prevent the overlooking of leaks in untested parts of the device.

5. Medical leak tests must be designed to accommodate medical devices

The functioning of medical devices often requires very slight volume fluctuations that could potentially change pressures throughout the device in such a way that leaks develop. Medical device materials often need to be elastic and flexible so that volume can flow naturally. This means that leak testing methods must show results that are applicable with any possible measure or volume change.
