  • Patent number: 4307043
    Abstract: An optical section of an intraocular lens has a pair of spaced apart threaded recesses which are threadingly locked to threaded shank sections of an iris retention loop. The shank sections are integrally joined to such loop so each shank section acts as an anchor preventing a screwing movement of the other shank relative to the optical section. A method is described of expanding a shank section of a lens retention member in situ within a threaded or other undercut recess of an optical section of an intraocular lens.

  • Patent number: 4302852
    Abstract: A hypoallergenic surgeon's glove with an allergenic elastomeric support glove, such as natural latex, has secured to its inner surface by covalent chemical bonds a barrier glove of a nonallergenic elastomer, such as silicone. Sharp angular flexing in the knuckle area, as well as stretching and snapping during donning, does not crack the barrier glove nor delaminate it from the support glove. This hypoallergenic glove requires only about 1/3 the amount of lubricating donning powder in a natural latex glove. In another example, a slip resistant glove, such as silicone, is secured by covalent chemical bonds to an external surface of the support glove.

  • Patent number: 4302857
    Abstract: An infant bathing bassinet with a wheeled tub support and a wheeled supply cabinet that nests with this tub support from a frontal direction. A coupler temporarily joins the tub support and supply cabinet so they can be wheeled about as a unit. The supply cabinet has a pair of openable front doors which can widely swing open through an angle of approximately 270.degree. without interferring with the tub support structure.

  • Patent number: 4284268
    Abstract: A medical examination table which has a pair of foot stirrups that are supported and moved by a pair of limb support bars. These limb support bars are longitudinally slidable within independent swivel collars within the table. A swivel lock means is disclosed for locking the limb support bars in a particular angular position, and there is also lock means disclosed for holding each bar at a particular length adjustment.

  • Patent number: 4276962
    Abstract: An improved system for actuating wheel engaging ring brakes for a hospital stretcher, bed, or the like. The brake includes an elongated rotational member extending longitudinally along the stretcher to actuate pivot arms adjacent one front wheel and one rear wheel to prevent the wheels from rolling. A separate elongated rotational member extends the length of the stretcher and actuates a bullet pin latch to lock a nonbraked wheel against swivel action. Thus, a single nurse can easily push and manipulate the stretcher about a hospital even when loaded with a patient.

  • Patent number: 4267835
    Abstract: A valve for an arterial monitoring set which continuously supplies a small flow of parenteral liquid, such as normal saline, into a patient's artery while arterial pressure is being continuously monitored. The valve has a flow restrictor providing a normally slow continuous flow rate and an elastically distortable tube which is manually squeezable to provide a fast flush rate. The valve is convenient for one hand operation. A method for assembling the valve by twisting the tube is also disclosed.

  • Patent number: 4267833
    Abstract: A method of flushing a medical liquid into a system that is continuously monitoring a patient's blood pressure. A parenteral liquid, such as saline, is flushed through a valve that has an elastic tube encasing a flow restrictor having a flow passage. The method includes passing the liquid through the flow passage at a predetermined rate, squeezing the tube to temporarily create an enlarged flush passage, and then releasing the tube to seal off the flush passage to force liquid through only the flow passage of the restrictor. This method of flushing can be conveniently carried out with one hand.

  • Patent number: 4267834
    Abstract: A system for continuously administering parenteral liquid, such as normal saline, to a patient while blood pressure fluctuations are continuously monitored. The system includes a flushing valve with a manually squeezable and distortable elastic tube surrounding a flow restrictor. The flushing valve is connected through a flexible tube segment to a T-connector of the system to provide for convenient one hand flexible operation. The flushing valve, flexible tube segment, and T-connector are joined as a unit for assembling into the system.

  • Patent number: 4266558
    Abstract: A method of collecting a blood sample, such as from an artery, in a flexible tube collector while forcing at least a portion of the air in the collector through a "nonwet" filter by means of blood pressure. This nonwet filter prevents escape of blood from the collector. The blood containing blood sampler can then be chilled in an ice bath if a test is not run immediately, and then the test sample dispensed to a machine for testing the partial pressure oxygen and carbon dioxide in the blood. If the machine does not have a vacuum extractor, blood can be stripped from the tube by a movable clamp structure.
