Vital Signs designs, manufactures and markets medical products for the anesthesia, respiratory, critical care, sleep therapy and emergency markets. A number of single-patient use products are increasing their share of the medical products market primarily because of their cost advantages and improved patient care features, including reducing the potential of transmitting infections from one patient to another. With the acquisition of Breas Medical AB ('Breas') from 1997 to 2002, National Sleep Technologies, Inc. in 2000, and the merger of HSI Medical Services Corporation in 2002, we have expanded our focus into the sleep therapy and personal ventilation markets.
We pioneered the development and introduction of a variety of single-patient use products. In 1975, we commenced the marketing of clear, non-conductive anesthesia breathing circuits. The first clear plastic, single-use air-filled cushion face mask for anesthesia delivery and resuscitation was launched by us in 1981. We were the first organization to introduce a single-patient use manual resuscitator in 1984. The first single-patient use laryngoscope system for use in the anesthesia and critical care arenas was developed and launched by us in 1988. We have also developed a general anesthesia kit, which can combine over 20 disposable items in one convenient, cost-effective package, and the first single-patient use infant resuscitation circuit with an adjustable pressure limiting valve, used to protect the infant's lung against over pressurization.
We also offer products and services for the sleep disorder/personal ventilation markets, which builds upon our airway management expertise. Our products are used in the treatment of obstructive sleep apnea, a condition caused by a blockage of the airway, usually the result of the soft tissue in the rear of the throat collapsing and closing during sleep. We operate a number of sleep diagnosis centers which test the need for sleep apnea products in particular patients and tailor specific products for individual patients.
We deliver regulatory compliance services to FDA regulated companies primarily to the pharmaceutical companies. In addition, we also offer services to medical device, diagnostic and biotechnology companies.
