Established in 1859

Manufacturing blood pressure sphygmomanometers

Founded in 1859, with an excellent reputation for quality which spans more than 150 years. Originating in the UK from the glass blowing industry, Alfred Charles Cossor and his son Frank Cosser developed innovative products which include x-ray tubes and light bulbs.

In 1904, the company manufactured one of the first ever blood pressure sphygmomanometers using their expert glass blowing skills to produce the ACCOSON glass manometer.

ACCOSON sphygmomanometers are renowned for their accuracy and ease of use. A full range of models are now available with accessories and spare parts for all their equipment.

Each product is manufactured to the requirements of the current European Standard, under the Quality Assurance Standard EN ISO 13485:2012. Our in-house research and development enables us to exceed both USA and European error standards and continue innovating for the next generation of blood pressure devices.

The Greenlight 300

The greenlight 300 model has been developed to provide a reliable and accurate alternative to the mercury sphygmomanometer.
It has been designed in the United Kingdom within the NHS for the NHS. The project, which was the result of cooperation between the Freeman Hospital, University of Newcastle and A C Cossor & Son (Surgical) Ltd won a DTI award for Technology Transfer.

The strength of the greenlight 300 is that it is suitable for any patient group (including the pregnant and the elderly) where mercury was used in the past. The reasons for this are as follows:

  • It is a manual device
  • It displays every 2mmHg
  • It is easier to read than mercury
  • It is calibrated to 0.4mmHg
  • It carries out an auto calibration to zero each time it is switched on
  • The cuff deflation rate is displayed
  • Any cuff size can be used
  • Frequent calibration checks are not required
