ATEQ designs its testing equipment to comply with international quality standards such as ISO 13485, which is specific to medical devices. This standard ensures that ATEQ’s manufacturing processes are capable of consistently meeting customer and regulatory requirements. Equipment designed and manufactured under these standards helps medical device companies comply with their regulatory obligations.

Leak testing is equally crucial for medical devices. A blockage or leak in a medical device can have serious implications for patient safety:

  • Patient Safety: The foremost concern in the medical industry is patient safety. Leak testing ensures that devices intended to be sterile, such as surgical instruments, implants, or infusion pumps, remain airtight to prevent the infiltration of bacteria, viruses, or other contaminants. This is crucial to avoid infections or other complications during medical procedures.
  • Device Functionality: Many medical devices, such as blood filters, catheters, or dialysis equipment, rely on maintaining specific pressure conditions to function correctly. Leak testing helps ensure that these devices meet their functional requirements without failing under normal usage conditions, which could lead to severe consequences for patients.
  • Regulatory Compliance: Medical devices must comply with stringent regulations set by bodies such as the FDA (Food and Drug Administration in the USA), EMA (European Medicines Agency in Europe), and other international health authorities. These regulations often require proof that the devices can maintain their integrity under expected conditions of use. Leak testing is part of the validation process needed to meet these regulatory standards.
  • Product Reliability and Quality: Consistent and reliable performance is essential for medical devices. Leak testing is a quality control measure that helps manufacturers ensure each product meets predetermined specifications and quality standards before it reaches the market. This not only helps in maintaining brand reputation but also minimizes the risk of product recalls that can be costly and damage a company’s reputation.
  • Cost Efficiency: Detecting leaks or defects during the manufacturing process reduces the cost associated with returns and repairs after the products have been distributed. Effective leak testing can reduce the occurrence of failures in the field, thereby decreasing the warranty claims and associated costs.
  • Longevity and Durability: Ensuring that medical devices are leak-proof enhances their durability and longevity. This is particularly important for devices that are implanted in the body or are intended for long-term use.
  • Legal and Ethical Responsibility: Manufacturers of medical devices have a legal and ethical responsibility to provide safe and effective products. Failure to conduct proper testing can lead to legal consequences including liability suits, particularly if a device failure causes injury or death.

What kind of products can be leak tested in medical devices?

  • Catheters: Catheters are commonly used medical devices for fluid drainage, infusion, or monitoring. Leak testing ensures that catheters maintain their integrity, preventing unintended fluid leakage into or out of the body.
  • Bags and Tubing: Bags and tubing deliver fluids (such as saline, medications, or blood) to patients. Leak testing ensures that these components are free from leaks, preventing contamination or fluid loss.
  • Blood Bags: Blood bags store blood for transfusions. Leak testing ensures that blood bags remain sealed and sterile, preventing any leakage that could compromise patient safety.
  • Medical Pumps: Infusion pumps, insulin pumps, and other medical pumps deliver precise amounts of fluids or medications. Leak testing ensures that these pumps function correctly and do not leak
  • Blister Packs: Blister packs are commonly used for packaging pharmaceuticals. Leak testing ensures that the blister packs are sealed properly, maintaining the sterility and efficacy of the enclosed medications.
  • Implantable Medical Devices: Devices like pacemakers, cochlear implants, and neurostimulators are implanted inside the body. Leak testing ensures that these devices are hermetically sealed to prevent fluid ingress or leakage.
  • Ventilators and Respiratory Devices: Leak testing is crucial for ventilators and respiratory devices. Proper sealing prevents air leaks, ensuring accurate pressure delivery and patient safety.
  • Balloon Catheters: Balloon catheters are used for procedures such as angioplasty. Leak testing ensures that the balloon remains inflated without any leaks during medical procedures.
  • Multi-Lumen or Multi-Flow-Path Devices: Devices with multiple lumens or flow paths (e.g., multi-lumen catheters) require leak testing to verify each channel’s integrity.
  • Stopcocks and Flow Controllers: These components regulate fluid flow in medical devices. Leak testing ensures their proper functioning and prevents unintended leakage.

Medical device manufacturers continue to increase the expectations of their quality standards in order to decrease and minimize risk. Therefore, medical device leak testing is of the utmost importance. ATEQ’s products are able to meet these demands. For example, our Leak Tester, allows for up to four separate channels of testing. Each leak test channel its own leak test transducer with less than 1.5 cc of internal volume.

Our products can be used in a manual or automated environment, and have secure features which limit who has access to entering and altering the testing parameters. ATEQ appreciates that when performing leak detection in medical devices, this may often include testing every single production piece. ATEQ’s leak detection equipment is built for high capacity testing, and includes quick access to calibrated leaks to verify that testing is progressing as expected

ATEQ’s products are in frequent use for medical device leak testing. End users require a high-degree of confidence in the medical field, like when leak testing ventilators, as they are often used to deliver or extract fluids to or from a specific part of the body.

If a leak existed, then fluids could be inadvertently sent to the incorrect location, or the wrong fluids could be removed. Either circumstance can result in dangerous consequences, and expose hazardous situations to healthcare professionals and patients. Ultimately, manufacturers can be held liable for the failures of their products.

Therefore, having a robust testing methodology can minimize these risks by identifying components that don’t meet established production standards.
