The present application discloses various embodiments of a hemostasis band comprising inflatable compartments and methods of using same. These inflatable compartments provide enhanced fit and/or comfort features.

The disclosure provides neck collar devices and systems for the mitigation and prevention of traumatic brain injury, including concussion. Specifically disclosed are adjustable collars and systems, and collars having certain pressure sensing devices.

The present invention relates a tourniquet, where tightening of the tourniquet is performed by linear motion by pulling a pull-cord. The tourniquet comprises a tensioning device and a strap. The first end of the strap is coupled to the tensioning device. The second end of the strap is wrapped around a limb and fixed to the tensioning device. The tightening of the tourniquet is achieved by pulling a pull-cord. Linear motion by the pull-cord is translated into winding up the strap inside the tensioning device, and thereby achieving a time-effective tightening of the tourniquet without the need of high forces.

A hemostatic device is disclosed, which capable of favorably maintaining strength of an inflatable portion and reducing a pressing force acting on a site where bleeding is to be stopped over time to such an extent that vascular occlusion can be prevented without operation by a doctor or a nurse. The hemostatic device includes a band for wrapping around a wrist, a fastener or means for securing the band to the wrist in a wrapped state, and an inflatable portion connected to the band and inflated by being injected with a gas, in which the inflatable portion includes a resin layer made of a resin material, a particulate portion dispersed in the resin layer, and a space portion formed around the particulate portion. The space portion contains gas dispersed in the resin layer so as not to communicate between an inner surface and an outer surface of the resin layer.

A system for diverting emboli within a patient can include a device that detects a presence of emboli in a first blood vessel of a patient. A compression member can be aligned with a second blood vessel of the patient when a collar supporting the compression member is positioned at least partially around a portion of the patient. In response to the detection device, a controller can actuate the compression member, when the presence of emboli is detected, from an unactuated state to an actuated state in which at least a portion of the compression member (i) is closer to the second blood vessel than while in the unactuated state and (ii) compresses and limits blood flow through the second blood vessel.

The invention relates to a compression unit adapted to be arranged around a patient's forearm to provide pressure to a radial artery puncture site, wherein the compression unit comprises a unit attachment band provided with a frame, and a compression element in the shape of an inflatable bladder, the compression element is further adapted to be arranged within said frame, such that when the compression unit is arranged around a patient's forearm, the compression element provides pressure to the puncture wound when the compression element is inflated. The invention also relates to a radial artery compression system.

A femoral compression device (11) for compressing a femoral artery (12) of a patient, having a base plate (13) provided with two opposing extensions, each of the two opposing extensions having a member for affixing a belt (14), which is adapted to be arranged around a patient's body, an inflatable air cushion (15), provided with a back plate (19), for compressive bearing against a puncture site, and a pump (16) connected to the inflatable air cushion for inflation of the air cushion. The femoral compression device further comprises a spacer (18) having a height and being adapted to be mounted between the inflatable air cushion and the base plate.

There is described a device for applying an adjustable and simultaneous compression on vessel access points. The device comprises a frame comprising a body with at least two cavities through the body to be placed about surfaces of a patient corresponding to the at least two cavities. At least two compression members are movably fitted in the cavities, wherein a portion of the frame defines a space into which a portion of the compression member is fitted and around which it hinges. A side of the compression members opposite a portion around which it hinges comprises a locking mechanism which releasably engages with the frame at an interface between said side and the frame to lock each one of the at least two compression members in a given hinge position for applying the pressure onto the vessel access point depending on the hinge position.

The invention features methods and devices for controlling bleeding from blood vessels that may be damaged as a result of trauma or impact with an object, such as a bullet or shrapnel. The device may be wearable by a user and include one or more components, such as wound sealant and multiple inflatable balloons/bladders. The device may be integrated into a garment, e.g., a vest, jacket, trousers, or full body suit. Once triggered (automatically or manually), the device may be used to deliver wound sealant to a wound site and/or pressure to the wound site by selective inflation of one or more balloons over exsanguinating blood vessels that may be damaged, thereby stopping or minimizing the bleeding. Alternatively, or in addition, the device may be used to stabilize a wounded wearer for, e.g., transportation purposes, or to provide buoyancy. Devices of the invention may also be used as a blood pressure monitor, as a massaging device, and as a breast pump.

Devices and methods of the invention may also be used for repairing or stabilizing machines, such as vehicles (e.g., automobiles and boats).

Apparatus, methods, and systems for junctional hemorrhage control and pelvic stabilization are provided. The hemorrhage control plate includes a baseplate and a bulbous node extending outwardly. It is positioned against a patient's body such that it aligns with an artery. It is used in connection with a tourniquet to occlude blood flow at a junctional hemorrhage site. The device includes tabs to attach to the tourniquet.
