The tension of the band is adjusted to apply a desired degree of pressure to the patient's abdomen to reduce loops in the patient's colon so that the colonoscope can be fully inserted into the colon with minimal discomfort to the patient. The ends of the device are connected together when the desired degree of tension is obtained so that constant pressure and support are provided to the patient's colon. Addition pressure can be manually applied simultaneously with the pressure from the tensile device to reduce or eliminate more distal loops in the colon.

  • Patent number: 9351737
    Abstract: An abdominal aortic tourniquet having one-piece member for the bladder and cover portions and whose bladder has a triangular cross-sectional shape when inflated that significantly increases the amount of point pressure such that the intended artery is properly occluded. The one-piece bladder/cover design provides for a reduction in cost of materials and provides for a more compact piece as compared to prior designs. The abdominal aortic tourniquet uses a single piece of weldable and gas impermeable fabric that is configured in a novel manner to create a three-dimensional, pneumatic piston while also serving as storage/transport cover, attachment structure, and major component of the belt member.

  • Patent number: 9039730
    Abstract: Disclosed is a method and apparatus for regulating tourniquet cuff pressure based on a personalized tourniquet pressure (PTP) to facilitate safe performance of a surgical procedure. The apparatus includes a dual-purpose tourniquet cuff adapted to encircle a region of a patient limb to provide both a sensor during a pre-surgical time period and an effector during a surgical time period. An effector module communicates pneumatically with an inflatable bladder of the cuff for maintaining pressure in the bladder near a PTP during the surgical time period to safely stop penetration of arterial blood past the cuff. A pulsation sensor that communicates pneumatically with the inflatable bladder during the pre-surgical time period senses and characterizes pressure pulsations that are indicative of penetration of arterial blood into the region of the limb encircled by the cuff.

  • Publication number: 20150133992
    Abstract: A method and device for reducing the damaging effects of radiant energy, blast, or concussive events includes applying pressure to at least one jugular vein to reduce the egress of blood from the cranial cavity during or before the incidence of the imparting event. Reducing blood outflow from the cranial cavity increases intracranial volume and/or pressure of the cerebrospinal fluid to reduce the risk of traumatic brain injury and injuries to the spinal column. Reducing blood outflow further increases the intracranial pressure and volume, and thereby increases the pressure and volume of the cochlear fluid, the vitreous humor and the cerebrospinal fluid to thereby reduce the risk of injury to the inner ear, internal structure of the eye and of the spinal column.
