Testing Devices for Respiratory Ventilators – Gas Flow Analyzers for Ventilators

Posted by:

Importance of Mechanical Ventilators & Respirators

To support patients with severe respiratory conditions that impact the lungs such as acute respiratory distress syndrome (a form of respiratory failure where the lungs become severely inflamed due to an infection or injury and can’t provide the body’s vital organs with enough oxygen), pneumonia, and COVID-19, ventilators are used to help patients breathe by getting oxygen into the lungs and get rid of carbon dioxide.

Respiratory Ventilator Manufacturing Challenges

With the current situation and increase in demand for medical ventilators, manufacturing experts and medical device makers are faced with the dilemma of whether newer companies that are not as familiar with this regulated sector are able to easily repurpose their shops to create these ventilators. In addition, the functionality ventilators are also questioned on how efficient and accurate they can simulate regular breathing patterns.

Gas Flow Analyzers for Ventilators:

Intertech Development Company offers a solution to testing the functionality for respiratory ventilators by providing precise electronic control of the vacuum ramp rate simulates different breathing patterns. IDC test devices for respiratory ventilators/instrumentation can confer a therapeutic benefit on a patient and ensure that specifications are adhered to and are acceptable for clinicians.

We have considerable test experiences and expertise in the Medical Device arena. Example applications include testing portable oxygen conservation devices (OCD) that minimize oxygen use because there are only flows when triggered by inspiration in a natural breathing cycle.

InterTech Medical Device Unit

The complete functional test of the system supplied by IDC for varying pressure ranges includes an auto triggering test to ensure that it does not operate unintentionally, a sensitivity test to detect the vacuum level at which the unit pulses, a pulse volume test at various positions to verify that the delivered volume is within the specification of each setting, continuous flow tests by selecting the control flow, a battery test at low-voltage pulse settings that test monitoring volumes, and an apnea test.

Ventilator Specification Requirements:

Our gas flow analyzers for ventilators are capable of simulating breathing functions to trigger a ventilator including adjustable inspiratory pressure and failure. Option to check ventilator over-pressure fail-safe function. Interactive HMI to provide operator prompts to select ventilator settings through the test cycle. Provide measurement of ventilator functions and provide alarms for:
• Respiratory rate / Inspiratory: Expiratory ratio (I:E)
• Plateau and peak inspiratory pressure expiratory pressure (PEEP), 0 to 100 cmH2O
• Tidal volume from 100mL to 800 mL

Intertech Development Company is ISO 9001 Registered and ISO 17025 Accredited. For more information on our testing technology capabilities and testing device for respiratory ventilators, contact the team at InterTech Development Company.

Electronics Component Testing – Smart Phones • Medical Wearables & Disposables • Cameras for AV applications •Lidar Enclosures

Posted by:

Rigorous testing of electronics’ sealed enclosures to IP67 standard is streamlined with superior mass flow leak test instruments.

The Challenge • Smart Phones • Medical Wearables & disposables • Cameras for AV applications • Radar/Lidar Enclosures

And more…

• Mass flow leak testing with the InterTech M1075 is non-destructive, clean and easily handles specifications of 0.5 sccm at pressure of 0.2 to 0.3 bar with fast test times. Because it effectively checks for gross leaks prior to fine leak testing absolute reliability is ensured. For example, a battery enclosure and valve are leak tested for IP 67 compliance at a rate of 120 parts per hour.

• In another application, Electronic Control Modules are tested in a two-step process – first for gross leakage, followed by a fine leakage test to 0.6 sccm limit and 10% Gage R&R.

LiDAR: The Use of Light Detection and Ranging Technology

Posted by:

LiDAR, short for light detection and ranging, is a remote sensing technology that uses light in the form of a pulsed laser to measure ranges (distances) to a target. A LiDAR sensor fires off beams of laser light and then measures how long it takes for the light to return to the sensor.

How can production line testing safeguard reliability and lifetime performance of electronics components?

The Challenge

• Smart Phones
• Medical Wearables & disposables
• Cameras for AV applications
• Radar/Lidar Enclosures
• And more…

These and similar electronics-based products can only be reliable if and when they are able to withstand dirt and water. Specifically, these electronics-based components must all meet or exceed IP67 ingress ratings.

That means they must be totally protected against dust and protected against the ingress of water in a harmful quantity after immersion in 1 meter of water for up to 30 minutes. Without proper IP 67 testing of sealed enclosure integrity, the lifespan and performance of a fast growing array of consumer and industrial electronics components cannot be assured.

InterTech M1075 – for unsurpassed leak testing speed and accuracy - using Mass Flow, Pressure Decay & Differential Pressure Testing

The Solution

An InterTech M1075 leak detector is used for fast and accurate testing to meet IP67 requirements. InterTech test technology automatically compensates for external changes such as temperature, and a unique test-centric design assures gage accuracy.

Mass flow leak testing with the InterTech M1075 is non-destructive, clean and easily handles specifications of 0.5 sccm at pressure of 0.2 to 0.3 bar with fast test times. Because it effectively checks for gross leaks prior to fine leak testing absolute reliability is ensured.

For example, a battery enclosure and valve are leak tested for IP 67 compliance at a rate of 120 parts per hour. In another application, Electronic Control Modules are tested in a two-step process – first for gross leakage, followed by a fine leakage test to 0.6 sccm limit and 10% Gage R&R.
