As the name suggests, oxygen bags are bags used to hold oxygen. They are mainly synthesized from materials that are non-toxic and have no harmful chemical effects.Oxygen bags are easy to carry and easy to operate. They can be used for home health care and can also be used for emergency transportation in medical units.Usually there is a rubber tube on the oxygen bag with a regulator on it to adjust the flow rate and the oxygen filled into the oxygen bag.Because the oxygen bag is used to store oxygen, if the sealing is not good, it will cause oxygen leakage and affect the user's use.Therefore, oxygen bag manufacturers will conduct air tightness tests on them.Today, Hirays Technology will share with you the air tightness testing method of oxygen bags, as well as the oxygen bagAir tightness detectorusage steps.

The locations where we need to perform air tightness testing are the rubber tube of the oxygen bag and the rubber tube inside the oxygen bag.The rubber tube of this oxygen bag has an inflation hole at the end. This product can be tested by direct inflation. You can directly connect the inflation hole of the test object to the inflation hole of the instrument.Our air tightness detector has eight test units. Usually we use the international standard unit KPA to set up the test program. This customer asked us to use the unit of millimeters of mercury for testing.The customer's test requirement is to use 300mmhg (equivalent to 39kpa), and the leakage volume should not exceed 6mmhg (equivalent to 0.8kpa). A qualified oxygen bag needs to meet two standards at the same time: the pressure can reach 300mmhg; the leakage value should not exceed 6mmhg. Set the program on the air tightness detector according to the customer's test value and save it. We can directly select this test program when we test.

Hirays HC ClassicAir tightness testing equipmentIt has 100 groups of subroutines. Each group of subroutines can be programmed independently and selected individually to meet various complex testing requirements.

The method of using the air tightness detector is very simple. You only need to connect the air source and power supply, connect the test product to the instrument, select the set program, and you can start the test.The instrument automatically determines OK or NG according to the set program.

In the medical industry, Hirays has tested many different products, such as medical irrigation guns, dental scalers, electronic stethoscopes, punctures, etc. If you are interested in air tightness testing equipment in the medical industry, please call Hirays Technology.The Hirays air tightness detector system is a self-developed intelligent analysis and control system HI-OS 2.0. It has powerful functions and stable testing.Recognized by thousands of customers.The main functions are briefly described as follows

High precision

Powerful 32-bit processor and 24-bit A/D converter, coupled with the patented "intelligent pressure difference" algorithm, the test accuracy is equivalent to that of the differential pressure type.Compared with the differential pressure type, the testable leakage range is larger, which is basically equal to the test range.

 AI algorithm

The automatic learning function can identify the characteristic information of the sample to be tested, analyze the valid data of the sample information, automatically judge and identify the critical point of the leakage volume, and obtain the optimal process time parameters through the analysis of the critical value, which greatly improves the difficulty of getting started with the instrument for the first time.

 Powerful testing capabilities

The system comes with 2 pressure forms and 8 basic judgment methods, which can be combined into more than 20 test functions to easily cope with various working conditions and meet your various requirements!

 Stable, reliable, improve efficiency

Built-in self-developed patented technology, "IVT" pneumatic sealing valve island; greatly improves test accuracy and speeds up inflation. At the same time, large leaks have been detected during the inflation stage, saving the entire test time.

The testing process is simple and more versatile

There is no need for standard parts, no need to make two sets of jigs, no need to compare with standard parts, and elimination of deformation errors after multiple tests of standard parts.

 More scalable

Modular design allows one host to control an execution module composed of multiple full-function valve islands according to requirements.Realize full-featured multi-channel testing including positive and negative pressure and indirect testing.
