||PCT/GB2014/000503||SMITHS MEDICAL INTERNATIONAL LIMITED||BATEMAN, Timothy|
A tracheal tube (1, 401) has a self-expanding sealing cuff (20, 408) towards its patient end (13, 407). The cuff (20, 408) is held contracted when the tube is inserted and removed by an outer sleeve (21) or tube (400) that is slid forwardly to contract the cuff. The sleeve (21) or tube (400) is slid rearwardly to allow it to expand and seal with the trachea T. The cuff may be of a resilient foam or may have one or more resilient strips (22, 122, 221, 321) extending between two spaced support rings (24) and (25) and covered by an outer flexible sheath (26).

||PCT/GB2014/000511||SMITHS MEDICAL INTERNATIONAL LIMITED||BATEMAN, Timothy|
The inflatable sealing cuff (2) at the patient end (3) of a tracheostomy tube is attached with the shaft (1) of the tube by two collars (24 and 25) turned inside out within the cuff. The upper collar (24) is attached with the shaft (1) along a line of locus in a plane P that is inclined to the diametrical plane D at an angle of between 5° and 45° so that secretions collect preferentially in a region around the opening (26) of a suction lumen (23). The shaft (1) is curved and the suction opening (26) is located on the inside of the curve, the upper end (27) of the cuff (2) being profiled to form a recess (28) in the region of the suction opening into which the secretions can flow.
WO/2015/107332 DETERMINING SENSITIVITY PROFILES FOR DAS SENSORS||WO||23.07.2015|
||PCT/GB2015/050055||OPTASENSE HOLDINGS LIMITED||HILL, David|
This application relates to fibre optic distributed acoustic sensing (DAS) applied using a sensing optical fibre (104) that is at least partly embedded in a cement structure (203) and addresses a problem of different acoustic sensitivities at different parts of the fibre (203). A method of producing an acoustic sensitivity profile is described which involves monitoring (501) temperature along the length of the optical fibre during curing of the surrounding cement structure. A temperature profile(301, 302) can then be generated (502) for the optical fibre based on said monitored temperature and used to generate (506) the acoustic sensitivity profile. The temperature profile indicates how well thermally coupled the fibre is to the surrounding cement, which also indicates how well acoustically coupled the fibre will be when the cement is cured. The sensitivity may be based on the rate of temperature change (303, 304) and/or magnitude of temperature change (T1, T2) during curing. The sensitivity profile can then be used to calibrate of adjust (604) measurement signals obtained using the optical fibre in a DAS sensor. The temperature during curing may be monitored using fibre optic distributed sensing such as DTS or DAS techniques.

||PCT/GB2014/000528||SMITHS MEDICAL INTERNATIONAL LIMITED||NAKAMURA, Takahiro|
An HME device (10) for a tracheal tube (1) has a housing (11) with an HME element (15) and (16) at each end and a central tracheal coupling (17) that fits on the machine end connector (5) of the tracheal tube. A suction port (20) is located directly opposite the tracheal coupling (17) and has an external screw thread (21) and an internal flap valve (22). A closed system suction catheter arrangement (30) has an internally threaded patient end fitting (31) that sealing couples with the suction port (20). A suction catheter (35) extends from the patient end fitting (31) to a machine end fitting (40) adapted to connect with a suction source (41), (42), (43). A flexible, protective envelope (46) extends around and along the catheter (35) from the patient end fitting (31) to the machine end fitting (40). The suction catheter (35) can be advanced into the tracheal tube (1), through the HME device (10) by manipulation through the envelope (46) without the need to directly contact the catheter.
WO/2015/107334 IMPROVED ISOLATION BARRIER||WO||23.07.2015|
||PCT/GB2015/050057||META DOWNHOLE LIMITED||MEIKLE, Duncan James|
An apparatus and method for securing a tubular within another tubular or borehole, creating a seal across an annulus in a well bore, and centralising or anchoring tubing within a wellbore. A sleeve is arranged on a tubular body to create a chamber therebetween. A port provides fluid access through the body to the chamber. A support frame of bow springs on mounts is located within the chamber. When fluid is introduced into the chamber the sleeve is morphed to secure it to a well bore wall, an end of the sleeve will move along the body and compress the frame and bow springs. The compressed springs support the sleeve to maintain a seal between the sleeve and well bore wall to form an isolation barrier.

WO/2015/107352 LINEAR ACTUATOR ASSEMBLY||WO||23.07.2015|
||PCT/GB2015/050084||HENROB LIMITED||GOSTYLLA, Wojciech|
A linear actuator assembly (1) comprises a linear actuator which has a housing and an output shaft, the output shaft (14) defining an actuator axis and being movable along the actuator axis between an extended position and a retracted position. The assembly also comprises a buffer carriage arranged in an active configuration in which it is mounted on either the housing or the output shaft. The buffer carriage (72) has a rotary portion (26) which is rotationally coupled to the output shaft such that rotation of the output shaft about the actuator axis requires corresponding rotation of the rotary portion. The rotary portion is rotationally restrained when the buffer carriage is in the active configuration. The one of the housing and output shaft on which the buffer carriage is not mounted has a first abutment surface which is positioned to act on the buffer carriage when the output shaft reaches one of the extended position and the retracted position, such that continued movement of the output shaft beyond said position moves the buffer carriage from the active configuration towards a first passive configuration. The rotary portion is rotatable about the actuator axis when the buffer carriage is in the first passive configuration.
