摘要： A catheter device is described with a safety needle guard that covers and protects the needle after use of the device. The device includes a semi-tubular needle housing containing a flash chamber with a hollow needle extending from the distal end of the flash chamber. A tubular needle guard concentrically fits and slides within the needle housing. The needle guard has a longitudinal slot through which the mounting base of the flash chamber passes as the guard slides within the housing. The top of the semi-tubular housing is open so that a user may access the top of the tubular needle guard with a finger to urge the needle guard to an extended position from the distal end of the housing and in a surrounding position about the needle. As the needle guard attains its fully extended position about the needle, it locks in place in the needle housing.

摘要： A looseleaf notebook is provided for retaining bar code listings which denote conditions of a patient in a hospital. The notebok includes a strap which encircles the binding of the notebook. Preferably this strap is fixed in place between the notebook ring mechanism and the inside of the binding panel of the notebook. The strap is also preferably adjustable or resiliently stretchable. The strap permits the notebook to be held open and manipulated by a user who slides a hand between the strap and the binding panel while supporting the opened covers of the notebook with the thumb and fingers of the hand. With the notebook being held in one hand in this manner, the user's other hand is free to manipulate a bar code reader over the patient condition bar codes, or to perform other information-gathering or medical functions.

摘要： A hinged plate diaphragm pump comprising a pumping chamber defined by an inflexible member and a flexible member opposed thereto. The flexible member has at least three inflexible plates with edges in a common plane. Each plate has at least two straight plate hinge edges, each plate hinge edge being adjacent to and aligned with a second plate hinge edge of an adjacent plate, the adjacent edges of each plate hinge edge and second plate hinge edge is attached together by a flexible hinge strip. Preferably, the plates comprise at least one array of plates positioned about an axial center of symmetry perpendicular to the common plane. The hinged plates can be hingedly connected to a surrounding support plate and an axially central plate positioned at the axis of symmetry.

摘要： A blood pressure cuff is applied about a subject's artery, and inflated above the systolic level thus fully occluding the artery for a full heart cycle. The cuff pressure is thereafter reduced to permit an increasing flow through the progressively less occluded artery, and a measure of the peak amplitudes of the successively encountered blood flow (oscillatory complex) pulses stored in memory. Also retained is the cuff pressure obtaining for each stored complex peak. In accordance with varying aspects of the present invention, the stored complex peak-representing data ensemble is corrected for aberrations; and improved data processing operates on the stored (and advantageously corrected) pulse peak data and the corresponding cuff pressure information to determine the subject's mean arterial blood pressure.

摘要： Automated blood pressure monitors utilizing a pressurized cuff are adapted automatically to work with a variety of cuff sizes, including neonatal. An acoustical pressure pulse is generated at the monitor, propagated to and through the cuff, and back to a pressure transducer in the monitor. The total time of propagation is indicative of the cuff size being utilized.

摘要： In the formation of a chemically sensitive field effect device, prior to formation of the gate membrane, an aluminum pad is disposed over the gate, and a polyimide layer is disposed thereover. Photoresist and etching steps produce openings in the polyimide to form a gridwork which is anchored to the device on the periphery of the gate. The aluminum layer is etched completely away, forming a void defined by the suspended polyimide mesh on one side, and the gate insulator on the other. Polymeric membrane is formed in the void by insertion in liquid form.

摘要： A polarographic sensor for blood oxygen monitoring is defined by respective anode and cathode electrode wires fixedly maintained in conventional fashion. The end cross sections of the wires are carried on a surface, and overlying this surface is a capillary pore ultrafiltration membrane. The microscopic capillary pores, which have diameters less than 12 micrometers each, pass water therethrough and thus allow the blood, which passes on the side of the membrane opposite the anode and cathode, to act as its own electrolyte.
