A compression device for freeing a ring trapped on a digit includes a rigid outer body. The rigid outer body includes a digit cavity extending from a cavity opening at a body proximal end of the body towards a body distal end of the body, a fluid inlet, and a fluid flow path fluidly connecting the fluid inlet to one or more inflation chambers positioned in the digit cavity. The body proximal end includes an upper portion, a lower portion, and two laterally spaced-apart side portions. At least one side portion is distally recessed as compared to the upper and lower portions to accommodate an interdigital fold. At least one flexible bladder lines the digit cavity, each flexible bladder defining at least one wall of one of the one or more inflation chambers.

The present invention describes a carrier that encases a tactical tourniquet, attaches to the user or the user's gear, and allows a person to quickly access the tourniquet to stop or slow traumatic bleeding. One embodiment comprises an open top half and an open bottom half which connect to encase the tourniquet. Each of the top half and bottom half are removably connected and are held together with a compressive band. Tourniquet rip cords extend through the carrier and may be pulled by the user. To access the tourniquet, the user pulls the carrier from the compressive band by pulling a rip cord. The carrier halves immediately fall apart after they are free from the compressive band, leaving the tourniquet available for immediate use.

Described embodiments provide systems and methods for an attachment mechanism for attaching a strap around a body extremity. The attachment mechanism includes a hook, a first channel, and a second channel. The hook includes a first longitudinal axis and coupled to the strap at a first region of the hook. The first channel allowing the attachment mechanism to receive the strap. The second channel extending from the first channel and having an opening allowing the attachment mechanism to secure the strap, the opening extending along a second longitudinal axis, the second longitudinal axis forming an angle of less than ninety degrees with the first longitudinal axis. The strap is coupled to a harness. The strap includes a first portion, an attachment portion attached to the first portion, a main portion attached to the attachment portion; and an elastic portion attached to the main portion.

Provided is a tourniquet holder comprising a mounting base adapted to be operationally engaged with a handguard of an associated weapon, a first tang, a second tang, and an elongated retention strap. The mounting base has a substantially flat plate defining a first base face and a second base face, one or more fastener apertures, and one or more retention slots. The first tang extends in a direction substantially normal to the first base face. The second tang extends in a direction substantially normal to the first base face. The first tang and the second tang define therebetween a margin adapted to accommodate therein an associated tourniquet. The elongated retention strap passes through the one or more retention slots, has a first end and a second end that are selectably engagable with one another to define a loop adapted to retain therein the associated tourniquet.

A radial artery sheath assembly includes a cuff that is wearable around a patient's wrist and a receiver is integrated into the cuff. The cuff is inflatable to compress an incision in the patient's wrist to achieve homeostasis for stopping bleeding. A ring is removably attachable to the cuff and a radial sheath is extendable through the ring to retain the radial sheath in the incision in the user's wrist when the ring is attached to the cuff. The ring is inflatable for compressing the radial sheath in the ring to inhibit the radial sheath from being removed from the incision. A lock is coupled to the ring and the lock releasably engages the receiver in the cuff for attaching the ring to the cuff.

A tourniquet is described that includes an outer strap that runs from a first end to a second end having a buckle. An inner strap is routed within the outer strap over a portion of its length and runs through a windlass, which is used to tighten the tourniquet. The inner strap is secured to the outer strap at a position spaced away from the first end of the outer strap and is also secured to the buckle.

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.

A thigh compression device and technique to control, time, delay and/or prevent excessive early venous enhancement relative to arterial enhancement and thereby improve and/or enhance MRA images, including peripheral MRA images, is disclosed. In one embodiment, the present invention uses a curved strip of material which is longer on the superior edge and shorter along the inferior edge. When wrapped around the conical shape of the thigh of a subject, for example, a human, the thigh compression device more uniformly conforms to and/or fits around the thigh, providing more even/uniform compression as well as reducing, minimizing and/or eliminating significant movement of the thigh compression device towards the knees of the subject. A snug fit on the thighs may also enable the thigh compression device to be inflated with less fluid, which is faster and less cumbersome for the operator.

A patient in whom blood diversion due to cerebral venous steal is present, and abolishment of the cerebral venous steal is indicated, is treated by increasing the cerebral venous pressure in the patient. This increase in cerebral venous pressure restores the collapsed cerebral vasculature, thereby increasing cerebral blood flow. The increase in cerebral venous pressure may be achieved using an occluding catheter in the superior vena cava or the internal jugular veins, using external compression of the cervical veins, or any other suitable mechanism. The occlusion may be controlled precisely during treatment, possibly as a function of cerebral blood flow, and after treatment the patient may experience a persistent effect because the cerebral vasculature is no longer collapsed.

Provided is a tourniquet including an internal expansion and contraction portion that includes a gas injection and discharge portion to allow injection and discharge of a gas and expands or contracts according the injection and discharge of the gas and an external accommodation portion that has an incision in a longitudinal direction at one surface to have an accommodation space in which the internal expansion and contraction portion is able to be accommodated.
