Assembly: term used to describe a manometric catheter.
Autoclave: a machine that sterilises instruments or materials
with pressurised steam.
Channel: an individual pathway within a manometric catheter
that leads to a single pressure recording point at a specified level
on a manometric catheter.
Cleaning: to use detergent and water to remove biological
matter from the exterior and if necessary, from the interior, of a
manometric catheter immediately following use, in preparation for
sterilisation or disinfection.
Customised catheter: a catheter made to specifications supplied
by customer. Usually used for research.
Disinfection: to cleanse so as to reduce the number of disease-carrying
micro-organisms to an acceptable level.
Extrusion: Silicone rubber tubing comprising a number of channels,
used in manometry.
Intubation: to insert a catheter into the gastrointestinal
tract to the required recording point.
Manometry: the measurement and interpretation of pressures
in the gut.
Micro-manometry: measurement of pressures with channels smaller
than 0.4 mm in diameter.
PVC: polyvinyl chloride. A material commonly used in manometry
Resistor: a device used to control water perfusion rate to
a calibrated rate.
Sensor: A device designed to respond to physical stimuli such
as temperature, light, magnetism, or movement, and transmit resulting
impulses for interpretation, recording, movement, or operating control.
On manometry catheters the sensors are the side holes and sleeve sensors
which respond to pressure.
Sidehole catheter: conventional water perfused manometry catheter
featuring directional sensors Sidehole sensors are holes in the side
of the catheter from which changes in pressure can be sensed from
a very localised region at the axial and radial position of the sidehole.
Silicone rubber: a synthetic, flexible rubber like material
that is highly heat resistant, durable and free of allergens or leachable
Sleeve sensor: device used to obtain continuous measurement
of sphincter pressure that is sufficiently long to retain contact
with sphincters as they move relative to the recording catheter.
Sphincter: A ringlike muscle that normally maintains constriction
of a body passage or orifice and that relaxes as required by normal
Sterilisation: the complete destruction or elimination of
all living microorganisms.
