  • Patent number: 10004515
    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.

    Abstract: A penis enhancement apparatus and method having a first ring and a second ring, wherein each ring is circular in shape having an opening for receiving a penis therethough. The method provides the steps of adjusting the rings to an appropriate size via securing a knot in each ring. The first ring is applied to the tip of the penis adjacent to the glans thereof. The second ring is placed onto the shaft of the penis near the scrotum, wherein the rings cause small tears in the tissue of the penis via putting pressure onto the tissue of the penis once applied thereto. Pressure is then manually applied to the scrotum in order to direct blood flow into the tissue of the penis, wherein the blood causes the small tears. As the small tears are repaired, the penis is enlarged due to the promotion of cell growth and cell division.

  • Patent number: 9814467
    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.

    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.

    Abstract: A tourniquet cuff has a body configured for being wrapped around a limb. The body has an unpressurized state and a pressurized state. A securing portion on the body is releasably engageable to the body. The cuff also has an indicator that operates in response to movement of the securing portion for locating where the securing portion engages the body in order to apply a predetermined amount of force sufficient to secure the body to a limb without causing significant venous occlusion at the limb when the body is in the unpressurized state.

  • Publication number: 20150051638
    Abstract: A high-performance tourniquet for use in rugged environments is disclosed. The tourniquet includes a strap which surrounds an extremity to apply pressure to the extremity. The strap is coupled with a latching mechanism which is operated via a handle to tighten the tourniquet. The ends of the tourniquet are configured to couple via a buckle system enabling a buckle frame to be passed over a buckle tongue. Alternatively, a quick-release stab-lock style fastener buckle may be used to couple the ends of the tourniquet. In either case the tourniquet is designed to enable a victim to personally don the tourniquet and apply the correct pressure. A handle protruding from the outer surface of the tourniquet may be rotated to tighten the tourniquet and apply pressure by moving the tourniquet ends relative to one another. The handle may be pulled outward to quickly undo the pressure.

  • 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.

  • Patent number: 8888807
    Abstract: A tourniquet for restricting a flow of blood in a body part is presented. In accordance with embodiments of the present invention, the tourniquet comprises a first elongated member, and a second elongated member in slidable engagement with the first elongated member. In addition, the tourniquet includes a tensioning mechanism connected to the second elongated member, wherein a compressive force is applied to the body part upon applying a tensile force to the second elongated member using the tensioning mechanism. The tourniquet is suited for emergency use, and may be applied by using only one hand. Thus, the tourniquet may be applied, manipulated and tightened by the wearer, even if the wearer is limited to the use of a single hand.

  • Patent number: 8845680
    Abstract: A radial artery compression device configured to be secured to a wrist or other portion of a patient to provide adjustable and consistent compression pressure in the area of a radial artery access site or other physiological portion of a patient to achieve hemostasis either during or after a medical procedure such as a percutaneous coronary procedure. The radial artery compression device includes a rotatable member and a compression pad adapted such that rotation of the rotatable member does not affect the rotational orientation of the compression pad. According to one embodiment of the present invention, a single rotation of the rotatable member results in complete extension or retraction of the radial artery compression device. According to another embodiment of the present invention, the rotation of the rotatable member results in a compounding of the extension or retraction of the compression pad relative to the body of the radial artery compression device.
