YY T 1543-2017 Nasal oxygen tube bonding connection firmness test

Nasal oxygen tubes are medical supplies made of soft polyvinyl chloride and silicone rubber, which are composed of
flared mouths, nasal plugs, heads, etc.

This product is made of soft polyvinyl chloride and silicone rubber as raw materials, nasal oxygen tube according to the type of structure is divided into double nose type, head ring type (large, medium and small), earring type (large, medium and small), single nose type, pediatric type, baby type, by the flared mouth, nasal plug, head ring, tee, adjustment buckle, nasal catheter, connecting catheter, two-way composition, baby type of connecting catheter and nasal catheter can be connected to use or optional use
.

This product is connected to the oxygen system for human oxygen inhalation Nasal oxygen tube is a kind of oxygen tube used by patients with respiratory difficulties and needing oxygen therapy in hospitals
.

It is an oxygen tube
that connects the oxygen inhaler and the patient's nasal cavity.

It is an important medical accessory
.

It works by attaching one end to an oxygen tank and inserting a plug into the patient's nostrils at the other end, allowing oxygen to be drawn into the lungs from the patient's
nostrils.

At present, the nasal oxygen tube commonly used in hospitals mainly uses the ear hanging type to insert the plug into the patient's nostrils, and then hang the tubes at both ends of the plug on the patient's ear to achieve the fixation of the plug and prevent the plug from easily leaving the patient's nostrils
.

Whether it is a separate nasal oxygen tube or a nasal oxygen tube used to connect with a humidification bottle or mask, it needs to meet the testing standards
set by the state.

According to the "YY/T1543-2017 nasal oxygen tube" standard requirements: about the bonding, connection firmness (1) nasal oxygen tube between the bonded parts should be firmly bonded.
Each bond should be able to withstand an axial static pull force of 30N and not rupture
for 15 seconds.

(2) The nasal oxygen tube and the components connected to it should be firmly connected, and each connection should be able to withstand the axial static tension of 15N for 15 seconds and must not fall
off.

Instruments: ETT-AM tensile testing machine Nasal oxygen tube connection firmness can be tested by ETT-AM electronic tensile testing machine, applied to a variety of materials for tensile, compression, tearing, peeling, deformation and other mechanical properties of the test, suitable for plastic film, flakes, composite materials, paper, rubber, textile, pharmaceutical packaging and other fields of physical and mechanical property testing, is a material manufacturers, research institutions for physical testing, research and quality control tools
