Abstract: A compound with topical anesthetic and plasticizing properties is dissolved in polymeric material of a medical device. Extrusion, co-extrusion and coating techniques to form endotracheal tubes, drainage tubes and other medical devices with the topical anesthetic are disclosed. A hydrophobic anesthetic compound such as the base form of lidocaine is used which is more soluble in the polymeric wall material of the tube than in water. As a result, the anesthetic compound is transferred only to the contiguous tissue of the body passage and not disseminated systemically through the aqueous fluids. The anesthetic compound diffuses to the surface of body tissue touched by the tube where its anesthetic effect suppresses discomfort and undesired rejection reactions.

Abstract: A compound with topical anesthetic properties is incorporated in polymeric material making up the wall of a tube of intubation devices for introduction into body passages of an animal. A hydrophobic anesthetic compound is used which is more soluble in the polymeric wall material of the tube than in water. Because of the hydrophobic properties of the anesthetic compound, a quantity of anesthetic compound can be stored in solution in the polymeric wall material of the tube and this stored anesthetic compound is not washed out by the aqueous fluid which is present in the body passage. As a result, the anesthetic compound is transferred only to the contiguous tissue of the body passage and not disseminated systemically through the aqueous fluids. When the tube is in place within a body passage the anesthetic compound diffuses to the surface of body tissue touched by the tube where its anesthetic effect suppresses discomfort and undesired rejection reactions.

Abstract: A method and apparatus for measuring the width of a small object between a pair of opposed edges thereof e.g. the width of a line on a semiconductor wafer, having a light microscope, a video system for receiving an optical image from the microscope and for displaying the image on a display surface having a reference datum, and an optical system for transmitting the optical image from the light microscope to the video system. In order to measure the width of the line of the wafer, relative adjustment is carried out between the optical system and the object to a first measuring position in which the image is moved across the display surface until a predetermined intensity level of one of the edges of the line is brought to a predetermined position relative to the reference datum. Further relative adjustment is then carried out to a second measuring position in which a further predetermined intensity level of the other edge of the object is brought to a predetermined position relative to the reference datum.

Abstract: According to the present invention, an airway humidifier for directly humidifying the air flow requirement of a respiratory tract during the inspiration phase of a breathing cycle is provided, which comprises a nest of relatively large bore, thin wall air transmitting elongated hollow fibers terminating at an output end that is adapted to communicate the merged flow through a tube to the respiratory tract, a water chamber surrounding said fibers and having sufficient rigidity to resist collapse when subjected to negative operational water pressure, a water source for water heated to about 105.degree. F. (40.degree. C.) and a water pump connected to said chamber and said source and adapted to maintain said chamber filled with water under negative pressure, said fibers having an internal diameter of the order of 0.

Abstract: A medical suction control unit of the type operated by occlusion of a control port to prevent entry of atmospheric pressure into a control chamber, in which the valving element is free to move bodily between open and closed positions in response to the closing and opening of the control port, with the vacuum bleed passage, which enables air to be withdrawn from the control chamber, establishing flow around the side of the valving element. The vacuum bleed passage is shown formed by a channel in one or the other of the contacting surfaces, at the point where the valve element rests upon a surface of the housing. The valve element is shown in the form of an elastomeric disk which has sufficient structural strength to resist detrimental deformation under vacuum, and which has sufficient thickness to guide itself in its bodily movement. In one form the unit employs a plug-form member attached to the valve element and entering the intake chamber to reduce objectionable noise.

Abstract: For determining blood pressure a cannula, insertable through a needle into the bloodstream, locates a flaccid, relaxed wall directly in the bloodstream. The relaxed nature of this wall allows direct transmission of the blood pressure to a neutral liquid in the cannula. The cannula transmits this liquid pressure out of the blood vessel to the remote pressure responsive indicator. Thus blood pressure can be directly measured without need of administering anticoagulants to maintain pressure-transmitting conditions.

Abstract: In a ready-to-fly kite having a central, longitudinal stiffening element and a flexible kite body that defines a pair of flexible wings, the axial stiffening element is comprised of a plurality of elongated stiff sections. These sections are connected together to fold relative to one another at a joint from an extended position in which the sections are axially aligned, end to end, to a folded position in which the sections lie side by side. The respective sections of the flexible kite body that correspond to the stiffener sections are free from axial restraint to permit folding of the flexible kite body sections with the stiffener sections. Also the flexible kite body sections are free from lateral restraint to permit rolling of the kite body sections together about the folded group of stiffener sections to provide a compact portable collapsed kite package.

Abstract: A self-sterilizing humidifier for air to be breathed, of the type having endless porous media driven to be progressively immersed in a receptacle. Means are shown for periodically providing throughout the effective volume of water in the receptacle heated water at a temperature above about 180.degree. F while the media drive is actuated, the heated water being sufficient to progressively expose the media to bacteria-killing conditions. In one embodiment a heater chamber automatically discharges a charge of water heated above about 180.degree. F into the receptacle. In one such case a thermal actuator has sensitive parts exposed to water in both the heater chamber and the receptacle, the actuator releasing the charge when water in the receptacle lies below its sensitive part, and water in the heater chamber has reached or exceeds the selected high temperature.

Abstract: A humidifier for air or gas flow to the lungs heats the flow and saturates it with water vapor. Heated water injected into a humidifying passage flows down multiple paths in the gas stream. Heating of the water is shown on a localized basis at sterilizing temperature while over-all temperature is kept lower using a heater combined with the pump of the injection line. All surfaces of the humidifier are shown exposed to the water; the gas outlet connection is shown communicating with a space between the water paths and the reservoir, and directed toward the reservoir; and the humidifying passage is shown as a tubular column holding a mass of tangled inert filaments.
