Abstract: A injection plug assembly for insertion internally into a walled structure to permit safe access to and wide distribution of a fluid, liquid or powder spray into that walled structure. The assembly comprises an elongated outer sleeve arranged to pinch any thickness wall structure and an elongated delivery bolt arranged to be received through the outer sleeve. The elongated bolt has a radially directed fluid distribution channel therein.

Abstract: Fluid, such as pesticide or the like, can be injected into a wall through each of a plurality of fluid-injection plugs that are mounted on the wall. Each plug includes a blind-ended bore and a fluid passage port that fluidically connects the blind-ended bore to the outside of the plug. A bore-closing plug is releasably mounted on each plug and is removed to provide access to the blind-ended bore and is then replaced to close the plug. Fluid, including air-entrained powdered substances, can be injected into the wall by connecting a suitable supply of the fluid to the blind-ended bore after the plug has been removed and forcing the fluid into the blind-ended bore. The fluid will then pass through the fluid passage port out of the bore and thus be injected into the wall.

Abstract: An integrated introducer and drive rod system used to position and attach a spiral-shaped, biological needle probe to a fetus during labor and delivery. The system ensures that the sharp, pointed, probe (typically, a fetal spiral electrode) remains protected in a retracted position inside the introducer until attachment to the fetal scalp is desired. The flexible drive rod of the system has a "C"-shaped safety ring with an outside diameter slightly less than the inner diameter of the introducer at a point on the introducer; a "C"-shaped radial web with an outside diameter only slightly larger than the inner diameter of the introducer creating an interference fit between the drive rod and the introducer; or a "C"-shaped segmented rib that engages the rear end of the introducer.

Abstract: A transducer-tipped intrauterine pressure catheter system for measuring, and delivering to an external monitor a signal representative of, the pressure in the uterus of a woman in labor. The system has a disposable catheter with an affixed asymmetric tip. A disposable, slotted, C-shaped introducer engages and positions the catheter. A reusable monitor cable has a second connector (which engages a first connector on the end of the catheter) on one end and a monitor connector (which engages the monitor) on its opposite end; the monitor cable transmits electrical signals from the first connector to the monitor. A test member is proximate the monitor connector on the monitor cable. The test member includes test circuitry assuring that the monitor cable, the second connector, and the monitor connector are operational. The test member also includes circuitry to "zero" the system.

Abstract: An intrauterine pressure catheter system for monitoring pressure in the uterus of a mother during labor and delivery. The system includes a reusable junction box with a needle communicating directly to a pressure transducer sensor. The sensor transmits changes in pressure to a conventional pressure monitor. A connector attached to the catheter is pushed into the junction box and is held in place by a plastic latch. Inside this connector are an elastomeric plug and an adjacent diaphragm. When the connector is installed in the junction box, the needle pierces the plug and the tip enters the air-filled volume between the plug and the diaphragm. Fluid pressure in the catheter is communicated to the diaphragm surface and, in turn, passed to the air in the volume between the diaphragm and the plug. Thus, the intrauterine pressure is transmitted directly to the sensor. The system may be zeroed to atmosphere by simply removing the connector from the junction box.

Abstract: A non-invasive, disposable, self-adjusting tocodynamometer (10) for monitoring uterine contractions of a patient during pregnancy, labor, and delivery The tocodynamometer includes a pressure-sensitive, fluid. filled bellows (20) responsive to changes in the hardness of the uterus during contractions The bellows has one face which projects into the patient's soft tissue in the abdomen and adjacent the uterus, rending the tocodynamometer sensitive even for obese patients. A plate (22) supports the bellows and provides structure for attaching the tocodynamometer to the patient. A wall (30) formed on the plate receives the bellows as it is compressed during use. A conduit (14) connects the bellows to a pressure transducer (12) which, in turn, is connected to a monitor (16). The bellows, conduit, and pressure transducer form a closed system containing the working fluid.

Abstract: Substituted phenyl-1,2,4-triazolo[4,3-b]pyridazin-3(2H)-ones, useful as anti-asthma agents.

Abstract: A vehicle cab has an airflow deflector (9) pivotally mounted on it for movement between a lowered position and a raised position in which the deflector is inclined upwardly and rearwardly from a front upper portion of the cab, and the deflector has, or is associated with, side and rear walls which together with the deflector define a compartment above the cab when the deflector is in a raised position. Access can be gained into the compartment from inside the cab. A bunk (11) can be provided in the compartment for a person to sleep in the compartment. Seats in the cab have back rests (4) which fold down on to the seats, or can be removed, so that a bunk, which is stowed at the back of the seats when not in use, can also be erected in the cab over the seats.

Abstract: A method of treating asthma in a warm-blooded animal using the compound 6-phenyl-1,2,4-triazolo[4,3-b]pyridazin-3(2H)-one.

Abstract: This disclosure describes novel substituted 6-phenyl-1,2,4-triazolo[4,3-b]pyridazines useful as anxiolytic agents.
