Anesthesia machine and ventilator is one of the important equipment in clinical anesthesia operation, they deliver oxygen and anesthetic to the patient through the pipeline, to ensure the patient's breathing and anesthesia effect. In the selection of pipeline materials, in addition to factors such as physical characteristics and mechanical properties should be considered, special attention should be paid to its impact on patient safety. This article will discuss the material selection of pvc anesthesia mask and its impact on patient safety.

First, the material type of pvc anesthesia mask

At present, pvc anesthesia mask materials are mainly divided into rubber, silicone and plastic. Rubber materials include natural rubber and synthetic rubber, natural rubber has good elasticity and wear resistance, but is susceptible to environmental factors and aging; Synthetic rubber has higher durability and chemical resistance, but the price is higher. Silicone material is widely used in pediatric and neonatal ventilator piping due to its softness and high temperature resistance. Plastic materials mainly include polyvinyl chloride, polypropylene and polycarbonate, etc., which have the advantages of low price, easy processing and easy cleaning, but there are certain quality fluctuations and safety risks.

Second, the impact of pipeline materials on patient safety

The selection of pipeline materials has an important impact on the safety and health of patients. First of all, the pipeline material should have good biocompatibility and will not cause damage to the patient's body. Secondly, the pipeline material should have good air tightness and pressure resistance to ensure the stability and safety of gas transmission. At the same time, pipeline materials should have good antibacterial and antiviral properties to reduce the risk of cross infection. In addition, the pipeline material should also have good mechanical properties and chemical stability, can withstand the pressure and temperature changes of the ventilator and anesthesia machine, while not causing contamination of drugs such as anesthesia and oxygen.

Third, the selection principle of pipeline materials

In order to ensure the safety and reliability of pvc anesthesia mask, the piping material should be selected according to the specific clinical needs and use environment. The following are several principles for the selection of pipeline materials:

Biocompatibility. The pipeline material should have good biocompatibility and will not cause any damage to the patient's body.

Air tightness and pressure resistance. Pipeline materials should have good air tightness and pressure resistance to ensure the stability and safety of gas transmission.

Antibacterial and antiviral properties. Pipeline materials should have good antibacterial and antiviral properties to reduce the risk of cross infection.

Mechanical properties and chemical stability. The pipeline material should have good mechanical properties and chemical stability, and can withstand the pressure and temperature changes of the ventilator and anesthesia machine, while not causing contamination of drugs such as anesthetic and oxygen.

Economy. The selection of pipeline materials should also consider its economy, including factors such as price, service life and maintenance costs.
