Abstract: An example instrumented formation tester for injecting fluids and monitoring of fluids described herein includes a downhole tool which can be deployed in a wellbore via a wireline or a drill string. The downhole tool may facilitate the injection of fluids into an underground formation, and the monitoring of the directions in which the injected fluids flow in the formation in an open hole environment. In particular, the downhole tool may be configured for removing the mud cake from a portion of the wellbore wall for facilitating a fluid communication with the formation to be tested.

Abstract: A pouch includes a front wall (22), a rear wall (24) having an entrance aperture (32), and a central partition (36). The partition divides the pouch into an entrance chamber (38) and a collection chamber (40) located one in front of the other. A pad (42) of superabsorbent material is located in the collection chamber (40) and extends above the lower level of the entrance aperture (32). In use, urine entering the pouch is directed downwardly and through a lower permeable region (36) of the partition, whereafter it is absorbed and gelled by the superabsorbent material pad. The urine is also wicked upwardly by the pad (42) so that the full height of the pouch can be used as a liquid-collection region.

Abstract: A bowel irrigation system having a probe connected to a reservoir that contains irrigating liquid. The reservoir is a sealed container acted upon by a pumping element. The user operates the pumping element to create pressure on the sealed container and thereby displace the liquid from the reservoir into the probe. An inflatable cuff may also be included for securing the position of the probe when in use. The system is portable and may be employed by a user without outside assistance.

Abstract: A probe for use with a bowel irrigation system that is suitable for use by persons suffering from limited limb movement. The probe includes a shaft with a liquid supply duct passing therethrough for supplying irrigation liquid from a proximal end of the shaft to an outlet on the distal end thereof. A flexible element having a liquid absorbent material is positioned near the outlet and expands upon contact with liquid to ensure retention of the probe when in use.

Abstract: A urine collection device, a band for retaining the device and a method for attaching a medical device to the wearer's body. A band has two tabs. Each tab has one end attached to the band and a free end for extending through a hole in the device and attaching to the band. The band with the device mounted to it can be retained on the wearer's body.

Abstract: An aim of the invention is to provide a simple and effective one-piece tap which can be readily and economically manufactured. A tap for a liquid container is made from natural or synthetic rubber or a resilient plastics material. It has a base portion 10 having an orifice 12 which serves as a liquid inlet therein, the base portion embodying a liquid exit means 14. It also has a resilient deformable closure portion 20, the closure portion being constructed to make a resilient snap-on connection with the periphery of the base portion, the closure portion being manipulatable and having a centrally located plug 22 extending towards the base portion. This plug can obturate orifice 12 thereby closing the liquid inlet.

Abstract: Downhole Torque and Rate of Penetration are utilized to develop indications of formations having high porosity or of the development of an undergauge bit. Downhole torque is normalized by dividing it by the product of downhole weight on bit and bit size to produce Dimensionless Torque while Rate of Penetration is normalized by dividing it by the product of downhole weight on bit and rotary speed. The values of Dimensionless Torque and Normalized Rate of Penetration are compared to "normally" expected values of these quantities. Deviations from the normal values are taken as an indication of the occurrence of bit penetration of a highly porous formation or of the development of an undergauge or damaged bit.
