A compression patch configured to achieve hemostasis in a living body, the compression patch including a compression feature extruding out towards a patient contact surface; a base configured to provide support to the compression feature, the base including an opening within a perimeter of the base; and a patch feature configured to provide stability to the compression patch by adhering to the patient contact surface.

This device is a combination of an expandable or inflatable bladder or balloon in conjunction with a rigid or semi-rigid skin contact surface or structure to reduce bleeding from a skin insertion wound site and a vascular wound site after a vascular intervention or surgical procedure is performed. The device may be held in contact or close contact with the skin by a circumferential band, a clamp or other mechanism and provides a more consistent and uniform surface area contact and compression force. The contact surface or foot provides a uniform surface area contact as compared to the ever-changing contact surface area from an inflatable bladder.

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.

Various implementations include a junctional tourniquet device including a threaded rod, a pressure plate coupled to a second rod end, and at least one ratchet lock defining ratchet lock threads. The ratchet lock is biased toward an engaged position and urgable toward a disengaged position. The ratchet lock threads are configured to be engaged with the rod threads in the engaged position and to be disengaged with the rod threads in the disengaged position. The threaded rod is movable in a first axial direction and a second axial direction. The rod threads and the ratchet lock threads are shaped to prevent the threaded rod from moving in the first axial direction when in the engaged position and to urge the at least one ratchet lock from the engaged position to the disengaged position when the threaded rod is moved in the second axial direction.

A hemorrhage control device includes a trocar having an opening at a distal end. An expandable balloon is disposed within the trocar, the expandable balloon being collapsed within the trocar in a stored condition, and the expandable balloon being movable out of the trocar, through the opening, into a deployed condition. An inflation tube is fluidly connected to an interior of the expandable balloon. A source of pressurized fluid is connected to the inflation tube, pressurized fluid being introduced into the inflation tube to pressurize and inflate the expandable balloon in the deployed condition.

A hemostatic device is disclosed that includes: a pressing member configured to compress a patient's first puncture site; a first band body configured to be connectable to the pressing member; a second band body configured to be connectable to the pressing member; and a third band body configured to be connectable to the pressing member. The first band body has a first one end portion connected to the pressing member and having a first rotation axis and a free first other end portion. The second band body has a second one end portion connected to the pressing member and having a second rotation axis and a free second other end portion. The first band body and the second band body are configured to be rotatable about the first rotation axis and the second rotation axis so as to rotate toward or rotate away from the third band body.

Disclosed is an intelligent femoral artery hemostasis device by compression, including a main body capable of automatic compression. The main body includes a compression mechanism and a pressing plate mechanism successively provided from bottom to top; a lift regulator is provided between the support column and the compression mechanism; the compression mechanism is further provided with a detector for bleeding detection; and the main body is further integrated with a power supply module, an operation module and a central processing module. This invention realizes automatic bleeding detection and automatic pressurizing, and ensures the integration and compactness of the device. The power supply module, the operation module and the central processing module are integrated in the main body, avoiding external connecting wires and making it convenient to use the device when the tourniquet works in a twining working condition.

A junctional tourniquet apparatus and related methods of use. An exemplary tourniquet has an inverted cone shape, wherein a narrower end has a mushroom shaped base that is pressed against a compression target and a broader end has a plurality of pass-through slots for straps. Another exemplary tourniquet has a broad plate component and a handle component. The handle component has a mushroom shaped base on a first end and a handle on a second end. The handle component passes through the center of the plate component with threads that allow the handle component to compress a target by twisting the handle.

The present invention relates to a femoral compression system (14) for applying compression against a puncture site of a vessel in a patient, and a method for applying compression with a femoral compression system. The compression system (14) comprises an inflatable compression element (15) adapted to apply a pressure against the puncture site, a tightening unit (23) adapted to extend around a part of, or the whole of, the patients body to fixate and to tighten the compression element (15) against the puncture site, a pump (16) adapted to inflate the compression element (15), a valve (17) adapted to deflate the compression element (15), a pressure transducer (18) adapted to sense the pressure within the compression element (15). The system further comprises a blood pressure pulse detector (19) adapted to sense the patient's blood pressure pulse and to generate a pulse signal in dependence thereto that is applied to a control unit (20) that is connected to the pump (16), valve (17) and pressure transducer (19), wherein the control unit (20) is adapted to control the pressure within the compression element (15) in dependence of the pulse signal, by applying control signals to said pump (16) and valve (17).

A hemostatic device can perform hemostasis by compressing a puncture site on a hand of a patient, and can prevent a movable range of fingers from being narrowed or can prevent misalignment at a wearing position, when the hemostatic device is worn on the hand. The hemostatic device has a covering portion to cover a site where bleeding is to be stopped on a hand of a patient, and a pressing portion that compresses the site where bleeding is to be stopped, in a state where the covering portion covers the site where bleeding is to be stopped. The covering portion includes a securing portion that surrounds at least a portion of the hand while covering the pressing portion, and a restriction portion that restricts a movement of the securing portion in an axial direction. The restriction portion is disposed between adjacent fingers and of the hand.
