Flexible hose assemblies- accessoriesformedicalgases

Given the use of gases and vacuum in the medical practice there is a necessity to improve the feeding equipment - particularly hoses. Vacuum stations, gas cylinders, oxygen concentrators, cryogenic gasifier, room terminals, gas distribution console as receiving terminals may be mobile, located in different parts of ward. Supply circuit can pass through the humidifier oxygen filter installation. Given this, there is constant danger of tubes displacement, twist, bend (when moving equipment), and as a consequence - the need for advanced components and accessories for medical gases and liquids.

Tubes for gasessupply systemare classified by material (PVC, silicone, rubber, polyurethane, polyethylene, polypropylene), by function (connection, drainage, suction, feeding, to bypass), they could be transparent and colored roentgenopaque; single-channel and multi-channel.

Ramps, ceilings andconsoles avoid bending and squeezing of tubes through their reorganization and redirection along their own hard skeleton. WestMedGroup delivers ramps and consoles produced by MZ Liberec. The tubes can have probes with quick connectors, the filter tip.


Siliconegasessupply system

Silicone - material №1 in medicine because of its absolute inertia. Silicone may be used in situations where it is impossible to use conventional elastomers. For example, silicone O-rings resistant to ozone, salt and fresh water (including boiling), alcohols, mineral oils and fuels, dilute solutions of acids, alkali and hydrogen peroxide. In addition, silicones are resistant to mechanical stress, have the ability to increase or decrease the adhesion, have hydrophobicity, work at high humidity, bioinert, environmentally friendly. Silicone products tolerate extremes of temperature, retaining its properties from -60 ° C to +200 ° C, cold-resistant types - from -100 ° C, heat-resistant - up to +300 ° C. Silicone tubing can withstand pressures up to 2 atm.

PVCgasessupply system

Polyvinyl relates to a thermoplastic synthetic material. Depending on the polymerization conditions to produce various degrees of polymerization with different physico-chemical properties.

Materials on the basis of PVC are produced in two forms:

using plasticizer (plasticized PVC);

without the plasticizer (unplasticized PVC).

Other designations:

FPVC, PVC-F, PVC-P (plasticized);

RPVC, PVC-R, PVC-U (unplasticized).

PVC is not soluble in water, resistant to acids, alkalis, alcohols, mineral oils swells and dissolves in ethers, ketones, chlorinated and aromatic hydrocarbons. PVC combined with many plasticizers (e.g. phthalates, sebacates, phosphates), resistant to oxidation and practically non-flammable. Polyvinyl chloride has a low heat resistance, when heated above 100 ° C significantly decomposes in HCL. To improve the heat resistance and improve the solubility of PVC is chlorinated.

Polyurethanegasessupply system

Polyurethanes can be viscous liquid or solid substances in an amorphous or crystalline state. Their properties range from highly elastic soft rubber (Shore scale 15, A) to rigid plastics (Shore scale 70 D).Polyurethanes are resistant to acids, mineral and organic oils, gasoline, oxidants and hydrolytic stability are superior for polyamides. Linear polyurethanes are soluble in polar solvents such as dimethylformamide, dimethylsulfoxide. Polyurethanes are little susceptible to aging, resistant to abrasion and are highly resistant to environmental influences (ozone, UV rays and salt water).Under constant dynamic load upper limit of the operating temperature must be considered +100 ° C (except for MCS-PFL 100 M to +150 ° C). Changes in elasticity and hardness arising at temperatures below minus 18 ° C are reversible. Fragility begins to appear at temperatures below -60 ° C. The elastomers have excellent resistance to oils and solvents and is suitable for use with lubricating oils, petroleum and its derivatives, have no ozone aging, have high resistance to microorganisms and molds.

They have a high chemical stability and inertness, show increased resistance to chemically active habitat. Operating temperature range:

- Polypropylene tubes at - 100 ° C

- In plastic tubes - up to 75 ° C.


Biocompatibility with body tissues, hemocompatibility, noninvasive.Resistant to water extraction system, blood and other biologically active solutions. Enjoy a moderate rate of biodegradation. Resistant to mineral and other chemical environments. Along with increased flexibility have high mechanical strength and high resistance to shock. Have low density (about unity).
