Float-Type Oxygen Inhaler Verification Device (Digital): Integrated Solution for Medical Oxygen Terminal Equipment Metrology Verification

Product Overview and Application Value

The float-type oxygen inhaler, as the terminal equipment of the medical central oxygen supply system, is directly related to the treatment effect of emergency oxygen supply and hypoxic patients. Whether its flow regulation, humidification function and pressure reduction performance are accurate and reliable directly affects medical safety. In the monitoring of medical device adverse events, there have been accidents where accompanying personnel were injured due to the rupture of humidification bottles. Therefore, regular verification of oxygen inhalers has become an important measure for medical institutions to ensure patient safety.

The Nexisense Float-Type Oxygen Inhaler Verification Device (Digital) is specially designed to solve the above problems and complies with the requirements of JJG 913-2015 "Verification Regulation for Float-Type Oxygen Inhalers". Through the comparison method principle, it synchronously verifies the flow indication value, output pressure and humidification bottle pressure resistance performance of the oxygen inhaler, providing efficient and accurate verification means for hospital metrology rooms, medical device verification institutions and central oxygen supply system maintenance. The device helps medical institutions improve the accuracy and reliability of medical measuring instruments and ensures scientific oxygen management and medical quality.

Verification Principle and System Composition

The verification device adopts the comparison method working principle: install the float-type oxygen inhaler under test on the verifier, connect it to a medical oxygen cylinder or oxygen source through a special connecting tube. First check whether the pressure reducer leaks, then read the oxygen gauge indication value of the oxygen inhaler under test and compare it with the indication values of the standard flowmeter and standard pressure gauge to determine whether the equipment is qualified.

The humidification bottle pressure resistance test is carried out under (0.35±0.05) MPa pressure to confirm that there is no risk of rupture. The standard system mainly consists of a float-type oxygen inhaler verifier, a medical oxygen cylinder and a special connecting tube. The verification process strictly prohibits oil, and there shall be no grease contamination sources near the workbench to ensure safety and compliance.

The device has a built-in oxygen flow switching valve, which can quickly switch between flow and pressure verification ports, realizing comprehensive verification of inhaler flow, output pressure and pressure reducer adjustment pressure, significantly improving verification efficiency.

Technical Features and Performance Parameters

The digital design makes verification data visible and recordable in real time, reducing manual reading errors and improving the objectivity and traceability of verification results.

Typical Application Scenarios and Project Integration Cases

In tertiary hospital metrology rooms, the device is used for batch verification of central oxygen supply system terminal equipment, simultaneously completing flow accuracy, output pressure stability and humidification bottle pressure resistance tests. Verification data directly generates standardized reports to meet metrology standard instrument management requirements.

Medical device verification institutions use it as a medical oxygen metrology standard device, integrating it into laboratory information management systems (LIMS) to achieve automated verification processes and electronic archiving of data. In a central oxygen supply system maintenance project of a large medical institution, after introducing the Nexisense digital verification device, the verification time per inhaler was shortened, the detection rate of humidification bottle safety hazards was significantly improved, and the risk of medical device adverse events was effectively reduced.

The device is also suitable for oxygen stations, emergency centers and community health service centers, supporting on-site or laboratory verification modes to flexibly meet the metrology assurance needs of medical institutions of different scales.

Selection Guide

When selecting, prioritize configuration based on verification range and accuracy requirements: 0.02-level pressure accuracy is suitable for high-demand metrology laboratories; 0.05-level or 0.1-level is suitable for routine hospital metrology rooms. The flow range of 1～10 L/min has covered most float-type oxygen inhalers. Special range requirements can be customized.

When considering verification throughput, it is recommended to choose the 7-inch touch screen digital version for easy data recording and export. For bulk purchase projects, optimization can be made according to actual oxygen source conditions and pipeline interface requirements to ensure compatibility with existing medical oxygen cylinders and connecting tubes.

Integration Precautions

During installation and use, the area around the verification workbench must maintain an oil-free environment. All pipelines and connecting parts must be strictly oil-free, and open flames are prohibited indoors. The inhaler under test must be left to stand for more than 2 hours at the verification ambient temperature before verification.

During operation, pay attention to controlling the humidification bottle pressure resistance test pressure within (0.35±0.05) MPa to avoid overpressure risks. Regularly perform traceability calibration on standard pressure gauges and standard flowmeters to maintain the metrological accuracy of the device. It is recommended to incorporate data recording into the medical institution's metrology management information system for easy traceability and auditing.
