Description

Dial-type tourniquet {DIAL TYPE TOURNIQUET}

The disclosed content relates to a tourniquet for stopping bleeding by compressing a bleeding site when bleeding occurs due to an accident or the like.

Unless otherwise indicated in the specification, the contents described in this identification item are not prior art to the claims of this application, and description in this identification item is not admitted to be prior art.

In general, tourniquets are intended to stop bleeding by compressing the bleeding area when bleeding occurs due to an accident, etc., and hemostasis by a tourniquet is performed by directly pressing the bleeding area or indirectly pressing the area around the bleeding area. .

Conventionally, a twist-type tourniquet in which a compression rod is inserted and rotated between compression cloths is used, or wounds have been hemostatically wound by bandaging while putting gauze in contact with the bleeding site.

However, if the bleeding site is an artery, a cut or a gunshot wound, a large amount of blood is bleeding and even a life-threatening emergency occurs.The conventional hemostasis method requires immediate response to various bleeding areas because various actions must be performed in a complex manner. There is a problem that the hemostasis effect is not only difficult, but there is a problem that the hemostatic effect is relatively different depending on the expertise or skill of the person who hemostasis.

Accordingly, there has been a demand for the development of a tourniquet to obtain a quick and efficient hemostatic effect regardless of the expertise or skill of the person who hemostasis.

As an example of such a tourniquet, Korean Patent Publication No. 10-2012-0098766 (published on September 5, 2012) discloses a tourniquet, a base having first and second ends, and a contraction band attached to and extending from the first end of the base. And, a handle coupled to the contraction band, a polygonal frame member and a self-tightening member coupled to the frame member, wherein the free end of the contraction band is sewn through the self-tightening buckle, and the first end of the base A tourniquet comprising a hook member attached and configured to engage the frame member is disclosed.

However, in the case of the tourniquet described above, there is a problem in that it is difficult to finely control the hemostatic pressure, as the handle is rotated at 180° angular intervals to tighten the contraction band by a certain amount to fix the handle.

As an example of a tourniquet for easily adjusting the hemostatic pressure, Korean Patent Laid-Open No. 10-2020-0110856 (published on 28 September 2020) includes a compression band member for pressing the bleeding area, and a compression band member for pressing the compression band member to be fixed by pressing the compression band member. It includes a QR lever (quick release lever) member, wherein the compression band member includes a first compression band, a second compression band inserted into the first compression band and coupled so as to be adjustable in length, and the second compression band A first bevel gear coupled to move in engagement with the gear groove formed on the surface, an insertion hole coupled to one end of the first compression band, and a coupling hole coupled to one end of the second compression band to insert the insertion hole. A second bevel gear that penetrates through the first compression band and engages with the first bevel gear, and a fixed shaft rod that is coupled to an upper end of the second bevel gear, A tourniquet including an adjustment lever rotatably coupled while having an eccentricity at both ends of the fixed shaft rod is disclosed.

In addition, as a dial-type tourniquet having a one-way clutch type tightening unit that rotates in one direction but does not rotate in the opposite direction, the Korean Patent Registration No. 10-1559761 (announced on October 19, 2015), the tightening unit , A first fastening member made of a belt-shaped fabric material, a second fastening member made of a fabric material having a belt-shaped, vertically penetrating groove formed in the center, and serrated in one member of the groove part in the longitudinal direction , A housing that is mounted on the first clamping member by clamping and has openings that open in both longitudinal directions of the first clamping member, and the second clamping member is inserted into the opening to guide the sliding of the second clamping member. And, mounted on the first tightening member, and having a cogwheel, a shaft and a dial knob, the cogwheel is connected to the dial knob through a shaft, and the cogwheel is engaged with the teeth of the second tightening member, and the When the dial knob is turned, the force is transmitted to the second clamping member, and the second clamping member slides to pressurize the wound area or the wound area, thereby inducing hemostasis.

However, in the case of the conventional tourniquet as described above, a rigid gear groove that is linked to the bevel gear must be formed on the compression belt whenever the QR lever is rotated, or it corresponds to the cogwheel formed on the axis of the dial knob on the pressure bag member. Since it is necessary to form a groove with a stiff toothed tooth, there is a problem that excessive pain is caused in the hemostatic site during actual hemostatic pressure.
