Problems solved by technology

One possible reason for the measurement error in the EIS technique is the difficulty in ensuring consistent pressure on the cervical tissue by the EIS probe
The mucus layer on the cervix affects tissue conductivity, adding more error

Embodiment Construction

[0068] It has been recognized that a non-contact and more in-depth assessment of the cervix can be achieved using a technique called magneto-impedance spectroscopy (MIS). It is already known that magneto-impedance spectroscopy is used to measure properties of brain and liver tissue (see for example IEEE Transactions on Biomedical Engineering Vol 50 2003 07 01, pp 870-880 Scharfetter et al), and it has been suggested as a method for quantifying ischemia. method, but has not previously been proposed as a method for measuring the structure, composition, and electrical conductivity of the cervix or other reproductive tract tissues. To obtain the sensitivity and accuracy required to use MIS in the cervical setting, many practical problems need to be overcome, and simply adapting known MIS techniques is not straightforward. In particular, there are difficulties posed by the limited working space for MIS probes in the cervical environment. Simply adapting known MIS probes for use in...

Abstract

An apparatus for determining the electrical conductivity of target cervical tissue using magnetic impedance spectroscopy comprises: an excitation coil for producing a magnetic field which is capable of inducing currents in the target cervical tissue; a gradiometer for detecting perturbations in said magnetic field caused by said induced currents, the gradiometer including screening means for minimising sensitivity to tissues other than the target tissue; and processing means for determining an electrical conductivity of said target cervical tissue from said perturbations.

Description

technical field [0001] The present disclosure relates to the field of devices and methods for determining the electrical conductivity of human or animal tissue, and in particular, but not exclusively, to devices and methods for determining the likelihood of preterm birth. Background technique [0002] Preterm birth is responsible for perinatal death in two-thirds of infants without structural abnormalities. It places a huge economic burden on scarce health resources, as each very premature baby born costs tens of thousands of pounds in neonatal care. When born before 28 weeks of gestation, 1 in 4 babies has a disability. These disabilities can cost hundreds of thousands of pounds a year to treat. There is also a huge psychological burden on the family, with one parent often having to give up work to care for a disabled child. Although the survival rate of preterm infants is improving, the rate of preterm birth is increasing and currently accounts for 7-12% of all newborns...
