Povey MJW, Tong J., Nelson PV and Jones GM. 'Particle measurement by acoustic speckle'. United State Patent, Patent No.6,481,268, November 19, 2002. (also: Norwegian Patent Application No.2000.5026; EPO Patent Application No.00308886.1).
Developed with AC Cossor & Son (Surgical) Ltd as part of their Accoson range of sphygmomanometers. It is known as the greenlight 300 because it displays pressure as a series of green LEDs up to 300 mmHg. It displays every 2 mmHg, encouraging clinical staff to read pressure to 2 mmHg as recommended by the British Hypertension Society. It also displays cuff deflation rate, to allow users to deflate at the recommended rate. It is a manual device, and is an accurate direct replacement for the mercury or aneroid instrument, avoiding the problems of mercury or the loss of accuracy with aneroid devices.

The Laser Doppler imager scans a low power laser beam in a raster pattern over skin or other tissue surfaces. Moving blood in the microvasculature causes a Doppler shift which is processed to build up a colour coded image of blood flow. The measurement is non contact and can register chronic changes or measure repetitively in quick succession. Perfusion at each image position is recorded at resolutions of 0.2 to 2.0mm for further analysis.
Mediplus and Gateshead and South Tyneside Health Authority. Non-invasive bladder pressure measurements. (UK Patent Application No. 1305010, November 1998; International Patent Application No. PCT/GB99/03612, November 1999).
Parker D and Harrison DK. 'Non-invasive measurement of blood analytes'. World Intellectual Property Organization 2000; WO 00/01294.
There is described a device for the non-invasive measurement of one or more analytes in a patient's body part which comprises a light transmitter comprising a plurality of transmitting fibres positioned to transmit light to the body part and a light detector comprising a plurality of light detector fibres positioned to detect light transmitted through or reflected from the body part. The device especially utilises the non-pulsatile element of a patient's blood. There is also a method of measuring blood glucose levels and a device programmed so as to calculate one or more of the haemoglobin index, the oxygen index and the blood oxygen saturation.
Female patients with abnormal bladder functions are required to use catheters to empty their bladder. A new catheter has been developed which makes the task easier. This device is currently undergoing clinical trials in three hospital centres in the North East of England. Features of this device include:
