As the name suggests, an oxygen bag is a bag used to store oxygen, mainly composed of non-toxic and harmless chemical materials. Oxygen bags are easy to carry and operate, and can be used for home health care as well as for emergency transportation outside medical units. Usually, there is a rubber tube on the oxygen bag with a regulator that can adjust the flow rate and the amount of oxygen filled into the oxygen bag. Because oxygen bags are used to store oxygen, if the sealing is not good, it can cause oxygen leakage and affect the user\'s use. So oxygen bag manufacturers will conduct airtightness tests on it. Today, Hai Rui Si Technology will share with you the airtightness testing method of oxygen bags, as well as the oxygen bagsAir tightness testerThe usage steps.

The locations where we need to perform air tightness testing are the rubber tube of the oxygen bag and the rubber tube on the inside of the oxygen bag. This oxygen bag has an inflation hole at the end of the rubber tube, which can be directly inflated for testing. The inflation hole of the test sample can be directly connected to the inflation hole of the instrument. Our airtightness tester has eight testing units, and we usually use the international standard unit KPA to set up the testing program. This customer requested us to use units of millimeter mercury for testing. The customer\'s testing requirement is to use 300mmhg (equivalent to 39kpa) with a leakage rate not exceeding 6mmhg (equivalent to 0.8kpa). A qualified oxygen bag needs to meet two standards simultaneously: the pressure can reach 300mmhg; The leakage value does not exceed 6mmhg. Based on the customer\'s test values, set up a program on the airtightness tester and save it. We can directly select this testing program during testing.

Hai Rui Si HC ClassicAirtightness testing equipmentHaving 100 sets of subroutines, each set of subroutines can be individually programmed, selected, and combined to meet various complex testing requirements.

The use of the airtightness tester is very simple. Simply connect the gas source and power supply, connect the test product to the instrument, select the pre-set program, and start the testing. The instrument automatically determines whether it is OK or NG based on the pre-set program

In the medical industry, Hairui Si has tested many different products, such as medical flushing guns, dental washers, electronic stethoscopes, punctures, and so on. If you are interested in airtightness testing equipment for the medical industry, please feel free to call Hairui Si Technology. The Hai Rui Si airtightness detection system is an independently developed intelligent analysis and control system HI-OS 2.0. It has powerful functions and stable testing. Recognized by thousands of clients. The main functions are briefly described as follows

high precision

Powerful 32-bit processor and 24 bit A/D converter, coupled with patented \"intelligent differential pressure\" algorithm, achieve testing accuracy comparable to differential pressure type. Compared to the differential pressure type, the detectable leakage range is larger, which is basically equal to the testing range.

 AI algorithm

The automatic learning function can recognize the characteristic information of the test sample, analyze the effective data of the sample information, automatically determine and identify the critical point of leakage, and obtain the optimal process time parameters through the analysis of the critical value, greatly improving the difficulty of getting started with the instrument for the first time.

 Powerful testing capabilities

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

 Stable, reliable, and efficient

Built in independently developed patented technology, \"IVT\" pneumatic sealing valve island; Significantly improve testing accuracy, accelerate inflation speed, and detect major leaks during the inflation phase, saving the entire testing time.

The testing process is simple and has stronger universality

No need for standard parts, no need to make two sets of fixtures, no need to compare with standard parts, and eliminate deformation errors after multiple tests of standard parts.

 Stronger scalability

Modular design allows for the implementation of an execution module consisting of multiple fully functional valve islands controlled by a single host according to requirements. Implement fully functional multi-channel testing including positive and negative voltage, indirect testing.
