With the development and progress of science and technology, the medical device industry/medical industry oriented towards public health is becoming an important part of emerging industries.The improvement of living standards has promoted public health awareness, which has also led to the rapid development of the medical device industry.Quality issues are crucial for the production of various device products in the medical device industry.When it comes to the quality issues of various components of medical devices during production, we may wonder whether this product has been inspected before leaving the factory.Air tightness testingThis is a quality control process.Once medical device products ignore the issue of air tightness, it will directly affect the health of the public.This article is based on the medical deviceAir tightness testingThe problem is briefly stated in the article, mainly from theAir tightness detectorIntroduction to applications in medical devices/medical industry and medical devicesAir tightness testerAn introduction to the advantages and disadvantages.

Under the new form of the market,Air tightness detectorIts application in the medical device/medical industry has also been widely recognized and popularized.Hirays Technology has always pursued independent innovation. Currently, Hirays TechnologyAir tightness testerIn various types of medical device productsAir tightness testThe research and development technology is quite mature. Currently, the products that are widely used include blood pressure monitors, electronic thermometers, endoscope capsules, surgical puncture devices, medical irrigation guns, electronic stethoscopes, medical teeth cleaners, medical urine bags, water storage bags, and various infusion and oxygen tube testing.

After publicity and promotion of medical products in 2017 and 2018, the development of the medical device industry will become an industry trend starting in 2019.Hirays Technology as aMedical device air tightness testingThe leader in the industry, meeting the needs of various medical devices and medical productsAir tightness testneed.On the one hand, thanks to the recent 10 years ofAir tightness detectorThe above research and development and investment, on the other hand, benefit from the product performance and after-sales service that have surpassed domestic peer equipment and foreign imported equipment of similar products.Air tightness testingequipment.

Of course, as the medical industryAir tightness detectorDemand continues to increase and develop.used in medical devicesAir tightness testingThere has also been diversification in testing methods, differentAir tightness testEach method has its advantages and disadvantages, we will briefly introduce them to you.

Bubble detection method: Inject a certain pressure of gas into the sealed product, and then immerse the product into water (or other liquids) to observe whether bubbles leak out; or apply foam liquid or soapy water to the surface of the product to see if bubbles are generated.(This method is backward, inefficient, pollutes or damages the product, manual judgment is inaccurate, and cannot be automated.) This is what people adopted in the early days.Air tightness testingmethod, which is no longer common in production lines, has been replaced by newAir tightness testerreplaced;

Pressure drop detection method: Fill the sealed workpiece with a certain pressure of gas, maintain the pressure for a period of time (2 to 5 seconds), detect whether the pressure drops, and observe and calculate the pressure changes to determine whether the product is leaking (the whole process is 5 to 25 seconds).this methodAir tightness detectorThe matching tooling fixture is extremely versatile and can be applied to semi-sealed products and fully sealed products.You can also pump air into a negative pressure inside the semi-sealed workpiece to detect leaks in the product (products that require external waterproofing can completely simulate the direction of water entering the product).The pressure drop method has high efficiency, strong versatility, high detection rate and non-destructive testing.of which multiple channelsAir tightness detectorIt is possible to detect multiple products at the same time, which is currently the mainstreamAir tightness detectordetection method;

Differential pressureAir tightness testingMethod: Also called the comparison method, it requires a standard non-leakage product (or a sealed tank whose internal volume of the workpiece is not much different from the volume of the tested product).The principle is to pass gas of a certain pressure into a sealed product to be tested, and at the same time, pass gas at the same pressure into a standard product, and wait for a while to observe the pressure difference between the pressure in the standard tank and the workpiece to determine whether the product leaks.thisAir tightness detectorThe detection method has high detection accuracy, but is not very versatile and requires two tooling. The detection cost is twice as high as that of the pressure drop type.
