Post-liposuction compression garment

A post operative compression garment to enhance fluid drainage from micro-incisions is breasts liposuction surgery has been developed. The garment consists of two components: the first component applies pressure on the breasts and the second, adjustable component applies compression pressure of a greater magnitude than the first which for..

Moulded filter media comprising a sheet of porous nonwoven material

A moulded filter medium, e.g. a filter cloth comprises a sheet of porous nonwoven material which is pre-moulded and pre-formed to conform to and snugly fit into the recesses and contours of a filter press plate. The sheet may comprise sintered partially fused particles of plastics, metal or ceramic or a cast acrylic or methacrylic resin o..

Disinfectant plastic sponge material

A germicidal absorptive material for use in surgical packings, sanitary tampons and similar uses is provided by a sponge-like matrix of polyvinyl alcohol-acetal copolymer to which is tightly bound a germicidal disinfectant dye. Polyvinyl alcohol-acetal polymer shows exceptional avidity for a number of disinfectant dyes, both acidic and ba..

Light and efficient nonwoven technology to enhance product properties and improve performance

Improvements made in spunbonding, melt blowing and coating to produce lightweight breathable nonwovens for hygiene products are considered. The Vaporweb process creates very lightweight products with properties suitable for the textile backsheets of diapers and feminine hygiene products.

Development of hollow fiber membrane systems for nitrogen generation from combustion exhaust gasPart I. Effects of module configurations

This study deals with nitrogen separation from carbon dioxide using hollow fiber membranes, having the ultimate objective of developing a hollow fiber membrane system for nitrogen generation from combustion exhaust gas. The membranes used were integrally asymmetric hollow fibers that were preferentially permeable to carbon dioxide, thereb..

Highly permeable polyethersulfone hollow fiber gas separation membranes prepared using water as non-solvent additive

Polyethersulfone (PESf) asymmetric hollow fiber membranes with excellent gas separation properties were fabricated from spinning solutions containing PESf. N-methyl-2-pyrrolidone (NMP) and water. Water was also used as the external coagulant. The internal coagulants used include water, ethanol, 2-propanol, the mixtures of ethanol/water an..

Surgical suture needle point shape inspection system

Disclosed is a surgical suture needle point inspection system that utilizes a backlight to project a silhouette of the needle onto an optical sensor for computer analysis. The system comprises an indexing turntable where the needle is held stationary by a clamp, and an optical sensor provided at one of three stations. These stations consi..

Round-round-swaging process for surgical suture products

Disclosed is the process for the round swaging of small surgical suture needles onto surgical suture material. A small suture needle, with a bore on the blunt side, is attached to either an absorbable or a non-absorbable suture. The process of fastening the thread into the needle includes the feeding of the material into the appropriate b..

Needlepunched non-resorbable matrices for tissue engineerign

Tissue engineering is concerned with the creation of biological substitutes designed to maintain, restore or improve the function of damaged tissues or organs. It is an emerging field that encompasses a range of applications including: the engineering of organs and tissues for implantation into patients; the delivery of biologically activ..

Measurement of nonwoven weight evenness using optical methods-the influences of temperature and humidity variations(Chinese)

Optical sensors are developed for measuring the weight evenness of nonwovens. The sensors implement infrared light as a light source to evaluate the weight of nonwovens. The analyses of measuring the light transmission of optical sensors are also presented, especially on the influences of the temperature and humidity.
