    CROSS REFERENCE WITH OTHER RELATED PATENT APPLICATIONS
    This application claims priority application serial number 61/285,157, filed December 9, 2009, which is incorporated herein by reference in its entirety. BACKGROUND OF THE INVENTION 1. Field of Invention
    The present invention relates to medical devices used in first aid. More specifically, this invention relates to improvements in turnstiles for measured emergency use. 2. Description of Related Art
    Blood loss is a leading cause of death in emergency situations where the injured person is alone or medical care is not readily available. Using a tourniquet to stop blood loss in an injured arm or leg is a well-known technique for stopping blood flow in these situations. In general, for emergency use where the victim is alone, the victim should be able to apply a tourniquet to their own arm or leg and stop the flow of blood using only one hand. A typical tourniquet is a band tied or wrapped around a part of the body, for example, an arm or leg, in an attempt to stop severe bleeding or uncontrolled bleeding in an emergency situation.
    In recent years, several tourniquets designed for one-hand application have become available. These turnstiles typically include a strap (10) coupled to a substantially rigid base (15) and threaded through or wrapped around a cable (20) as illustrated in Figure 1. In order to secure the turnstile around a member, the strap (10) is threaded through a buckle (25) and the cable (20) is twisted causing the strap (10) to contract circumferentially around the limb. A significant disadvantage of known tourniquets, under certain circumstances, is that they do not facilitate quick application to the limbs with the strap. In order to apply these immobilized members, the strap (10) must be manually removed from the buckle (25) and subsequently rotated around the immobilized member and replaced in the buckle (25) before being tightened. This process requires sharp concentration as well as precise dexterity, characteristics that the injured person often lacks during a crisis or a first responder in a high-stress environment. In addition, this process delays tourniquet application, where even a few seconds delay can cause fatal blood loss.
    Another disadvantage of tourniquets designed for one-hand application is that they are sometimes difficult to tighten even when the strap is coupled with the buckle, requiring several pulls on the strap and sometimes the assistance of a second hand. It is often necessary for the injured person to apply the tourniquet to their own limb. The injured person may have suffered severe trauma and may not be aware, have the patience or the strength to overcome application difficulties.
    The use of a tourniquet by military personnel, law enforcement personnel and first aid imposes weight and size restrictions. Such personnel carry a variety of critical equipment and are discouraged from carrying a tourniquet if it is too heavy or too bulky. Likewise, there is a need for a lightweight, low-profile tourniquet that can be quickly applied by a first responder or a victim using one hand. BRIEF SUMMARY OF THE INVENTION
    It is an object of the present invention to provide a lightweight and compact tourniquet suitable for one-hand application.
    It is a further object of the invention to provide a tourniquet suitable for one-hand application that is easily applied to immobilized limbs.
    It is another object of the invention to provide a tourniquet suitable for one-hand application that minimizes unwanted loosening.
    Yet another object of the invention is to provide a tourniquet suitable for one-hand application that minimizes unintentional decoupling.
    It is a still further object of the invention to provide a tourniquet suitable for one-hand application which provides an audible alert when the tourniquet is properly placed.
    In accordance with one embodiment of the invention, a tourniquet comprises a base having a first and a second end, a constriction band attached to and extending from the first end of the base, and a cable coupled with the constriction band. A self-closing buckle includes a polygonal frame member and a self-closing member coupled with the frame member and a free end of the tightening strap is threaded through the self-closing buckle. A hook member is attached to the first end of the base and configured to be coupled to said frame member.
    According to another embodiment of the invention, a turnstile comprises a locking assembly for turnstile.
    In one embodiment, a locking ring is secured to the structural member.
    In a further embodiment of the invention, at least one of the first and second ends of the cable is configured to be mated with the locking ring.
    In yet another embodiment of the invention, the locking ring is operatively associated with the cable and at least one of the first and second ends of the cable includes an engagement section that engages the locking ring.
    In yet another embodiment of the invention, the tourniquet includes a self-closing buckle including a polygonal frame member and a self-closing member coupled with the frame member, the self-closing buckle is configured to contain a strap of constriction threaded through you; and a hook member adapted for connection to a base of the tourniquet, the hook member includes a depression configured to engage the polygonal frame member.

It should be understood that other embodiments can be used and that structural changes based on currently known structural and/or functional equivalents can be obtained without departing from the scope of the invention. BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS
    The objects, advantages and characteristics of the present invention will become clearer from the following description, when read in conjunction with the attached drawings, in which:
    FIG. 1 is a plan view of a typical tourniquet.
    FIG. 2 is a perspective view of a tourniquet according to an embodiment of the invention.
    FIG. 3 shows a locking assembly for the tourniquet shown in FIG. two.
    FIG. 4 shows a top view of a hook member and the shock interface of the lock assembly of FIG. 3. DETAILED DESCRIPTION OF THE INVENTION
    As illustrated in Figure 2, the tourniquet in accordance with the invention includes a constriction strip (110) coupled with a base (115). The constriction strip (110) preferably has a width between about 1 inch and about 3 inches, more preferably a width between about 1 inch and about 2 inches. In a typical embodiment, the constriction strip is about 1.5 inches wide.
    The first end of the constriction band (110) is firmly fixed, eg stitched, to the base (115) at an attachment point attachment point (120). The constriction band (110) is then threaded through a and/or coupled to a tourniquet cable (125) and re-coupled with the base (115) at a second end as illustrated in Figure 2. For example, the band of constriction (110) can be sandwiched between the upper and lower layers of the base (125A) and (125B) near the second end of the base (125). The constriction band (110) then extends from the second end of the base (125) at least a sufficient distance to allow the constriction band (110) to be wrapped around the medium-sized limb of an adult male. In some embodiments, the tourniquet handle (125) may be secured to the base (115) in the manner described in US Patent 7,776,064 which is incorporated herein by reference.
    In accordance with the invention, a typical embodiment of the tourniquet according to this invention further includes a locking assembly (130) comprising a self-closing buckle (135) and a hook member (140). In some embodiments, the buckle (135) includes a polygonal frame member (137) having a self-locking member (139) coupled with the polygonal frame member (137). As illustrated in Figure 3, the self-locking member (139) comprises a structural member such as a handle or bar that extends through an opening of the polygonal frame member (137) and forms a tongue and groove type coupling with a opposite first side and second side of the polygonal frame member (137). The constriction band (110) is wrapped around the high-locking member (139) such that by simply pulling the free end of the constriction band (110), the self-locking member (139) slides along the tightening member. frame (137) in the direction of arrow (A) until the constriction strip (110) is clamped between the self-locking member (139) and the frame member (137).
    In the illustrated embodiment, the frame member (137) is hexagonal. However, the frame member (137) may have any polygonal shape that allows the self-locking member (139) to secure the constriction strip (110) against the frame member (137).
    The hook member (140) is pivotally secured to the base (115) near the first end of the base (115) and is constructed to form a friction fit with the frame member (137). As illustrated in Figure 4, the hook (140) comprises a handle having an inner surface (142). It is desirable to keep the hook (140) engaged with the frame member (137) unless and until a user actively disengages them. Likewise, in order to prevent unintentional decoupling that can occur, for example, when the tourniquet is bumped into a medical field, a first responder, military or walking equipment, the inner surface (142) is provided with a shock interface with a plurality of protrusions (144). The protrusions (144) lock the frame member (137) to the hook member (140) and minimize accidental disconnection. In addition, the protrusions (144) provide an audible alert, i.e., a click, when the user reconnects the frame member (137), informing him that the connection is secure.
    In keeping with one aspect of the invention, the hook member (140) has a length (L1) that is substantially less than one dimension along the length (L2) of the opening of the frame member (137). In one embodiment, L1=1/2L2. Since the opening size of the frame member (137) is greater than the length of the hook member (140), it is easier for an individual under stress to connect the hook member (140) to the frame member (137 ), in that it minimizes complicated motor movements and reduces the level of visual coordination required to connect the hook member (140) to the frame member (137). These are particularly important considerations in combat environments. Additionally, the side of the frame member (137) that engages the hook member (140) has a length (L3) that is only slightly longer than (L1), i.e. a few centimeters or less. This makes the connection of the hook member (140) to the frame member (137) easier, while minimizing undesirable relative movements, slips and/or rotations of the hook member (140) relative to the frame member (137).
    In another aspect of the invention, it is desirable to minimize loosening of the tourniquet such as can occur, for example, if the tourniquet is stuck during patient movement. Likewise, a loop (150) is threaded through an eyelet (148) and fixed firmly to the base (115), for example by stitching, so as to connect the hook member (140) to the base (115). The frame member (137) has a rectangular cross section. Likewise, when the frame member (137) is housed in the crescent channel of the hook member (140), as the tourniquet is displaced during patient movement or in tactical extraction, the hook member (140) is tilted from so as to pivot around the lug 5 (150) and is angled to pivot around the frame member (137) which minimizes the possibility of accidental loosening of the constriction strip (110).
    While the present invention has been illustrated and described by way of specific embodiments and alternatives, it is to be understood that numerous changes and modifications can be made without departing from the spirit and scope of the invention.
    Accordingly, it is to be understood that the invention is not limited in any respect except in accordance with the appended claims and their equivalents.
