  • Patent number: 10517606
    Abstract: The inflatable arm sleeve prepares an arm to receive a hypodermic needle. The inflatable arm sleeve comprises a tubular bladder and a pump mechanism. The tubular bladder is further formed with a needle aperture. The tubular bladder is placed around the arm in the manner of a sleeve such that the needle aperture is positioned over the vein of the arm. The pump mechanism introduces compressed air into the tubular bladder such that pressure is applied to the arm from all directions around the arm except the needle aperture. The applied pressure will force blood into the unpressurized region of the vein underneath the needle aperture. The increase in pressure increases the diameter of the vein to make it easier to insert the hypodermic needle into the vein.

    Abstract: A method and device for reducing the damaging effects of a blast or concussive event includes applying pressure to at least one jugular vein to reduce the egress of blood from the cranial cavity during the incidence of the concussive event. Reducing blood out flow from the cranial cavity increases intracranial pressure of the cerebrospinal fluid to reduce the risk of traumatic brain injury and injuries to the spinal column. Reducing blood out flow further increases the intracranial pressure, and thereby increases the pressure 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. In addition, increasing intracranial pressure reduces the likelihood of brain injury and any associated loss of olfactory function.

  • Patent number: 9011483
    Abstract: A surgical tourniquet cuff that includes a stabilizer component that facilitates application of an overlapping cuff around the limb of a patient. The stabilizer is fixed to the cuff, and requires no tying or similar user manipulation to secure the overlapping cuff in alignment with the underlying cuff. The stabilizer improves the stability of the inflated cuff to prevent sideways shifting motion of overlapping cuff portions as the cuff is applied to the limb. The stabilizer also provides a handle mechanism to enable the user to snugly apply the overlapping cuff around the patient's limb while the overlapping portions remain properly aligned along their long axes. The stabilizer is designed to also facilitate attaching together two tourniquet cuffs end-to-end, with respective bladders overlapping and in proper alignment so that those attached cuffs can be used as a single, extended surgical cuff applied around a patient's limb.

  • Patent number: 8911469
    Abstract: Ischemia-reperfusion injury commonly results from any surgical procedure requiring stopping of blood supply to an organ followed by reperfusion such as in heart bypass, angioplasty or organ transplant. The invention discloses a method to harness the innate power of repetitive transient ischemia in protecting organs against imminent ischemia-reperfusion, or any patho-physiological insults. This method of optimal remote ischemic preconditioning (ORIP) comprises of utilizing a pair of programmable pneumatic cuffs that inflate/deflate alternately occluding blood circulation to each of the limbs for pre-defined time intervals. The apparatus delivers maximal ORIP dose in shortest possible time either as an EMS procedure during patient transportation to hospital, as elective pre-surgery treatment, or in critical care for preventing multiple-organ-dysfunction-syndrome. ORIP can be self-administered and remotely monitored by clinician especially in chronic patients for homeostasis of malfunctioning target organs.
