Medical devices for use in cannulation or to stem the flow of traumatic bleeding, namely, tourniquets

Abstract

A pneumatic tourniquet has a constricting device that comprises a rocker, such that when the rocker is angularly displaced by contact with a wounded limb, a clamping force is applied by a rocker surface and a clamping edge onto a sealing element to prevent flow of the pressurized gas from an interposed inflated strap to a free end, causing the strap free end to be considerably thinner than the main strap section. In one embodiment, a gas flow control assembly comprises a casing containing a force transmitting element and a gas cartridge; and a pivotable activation handle, wherein, upon pivoted displacement of the activation handle, pressurized gas is caused to be discharged from the gas cartridge and flow to an interior of the strap. In other embodiments, the pneumatic tourniquet comprises one or more of a flow control unit, a manual pressure release initiator, and a puncture mitigating connection section.

Abstract

A tourniquet for use by different sized wound victims comprises a strap wrappable around a wounded limb to provide a desired hemorrhage suppressing force which is configured with first and second sections of different widths, in one embodiment, a gas flow control assembly of a pneumatic tourniquet comprises a casing which contains a longitudinally displaceable force transmitting element and a gas cartridge; and a pivotable activation handle, wherein, upon pivoted displacement of the activation handle about its axis of rotation, pressurized gas is caused to be discharged from the gas cartridge and flow to an interior of an inflatable strap to provide the hemorrhage suppressing force. In other embodiments, the pneumatic tourniquet comprises one or more of a flow control unit, a manual pressure release initiator, a puncture mitigating connection section, and a strap configured with an inner layer, an outer layer, and an intermediate sealant layer that are interconnected.

Abstract

A compressed gas container and a flow control unit are retained within a rigid housing of a control device locally attached to an inflatable strap of a pneumatic tourniquet. The flow control unit, when triggered, is configured to selectively supply a dose of pressurized gas discharged from the gas container to an internal strap cavity, to achieve a predetermined cavity pressure for applying a required hemorrhage suppressing force onto a limb. In one embodiment, a strap restraining unit permits displacement of a free end of the strap without resistance until assuming a predetermined length sufficient to apply the hemorrhage suppressing force and which corresponds to a disposition of a restraining element at which it is in sufficiently close pressing relation with the strap to cause it to become restrained. The tourniquet is deployable in one embodiment by engaging an unattached end of a buckle frame with a large-area protruding part.
