Nasal Oxygen Tube Comprehensive Tester - Technical Documentation Nasal Oxygen Tube is a type of oxygen delivery tube used in hospitals for patients with breathing difficulties and who need oxygen therapy
.
It is the oxygen delivery tube that connects the oxygen inhaler to the patient's nasal cavity
.
It is an important medical accessory
.
It works by attaching one end to an oxygen tank and inserting the plug into the patient's nostril at the other end, allowing oxygen to be drawn into the lungs from the patient's nostril
.
At present, the nasal oxygen tube commonly used in hospitals mainly adopts the ear-hook type to insert the plug into the patient's nostril, and then hang the tubes at both ends of the plug on the patient's ear to fix the plug and prevent the plug from easily detaching from the patient's nostril
.
According to the requirements of the YY/T1543-2017 standard, the nasal oxygen tube should meet the following test standards (this instrument can be used for testing) 1.
Airflow resistance: After adjusting the test pressure and rated flow, record the pressure value change before and after the nasal oxygen tube is inserted (△P=P2 -P1) is airflow resistance
.
2.
Flattening resistance: On the basis of completing the airflow resistance test, bend the end of the nasal oxygen tube into a U shape, and record the flow change after stabilization (△Q=Q1-Q2)
.
3.
Patency: Under normal oxygen pressure, ensure that the oxygen flow is not less than 15L/min
.
Technical advantages: comprehensive test function touch screen control, more convenient and quick operation interface The device is equipped with a micro-printer, which can print the experimental results in a timely manner
.
High-precision pressure sensor, the output pressure can be stably controlled by adjusting the pressure handle.
The stored data can be queried by micro-printer and general data interface, which is convenient for data export
.
Main parameters: Test range: 0～600 kpa Inflatable head specification: Inner diameter Φ5.
