On the other hand, the fixing strap 140 is coupled to the insertion hole 141 coupled to one end of the first compression band 110 and one end of the second compression band 120, and the coupling hole 142 into which the insertion hole 141 is inserted. ), so that the first compression band 110 and the second compression band 120 are initially set to have a certain length, and only by fixing them to the bleeding site, the primary compression and primary hemostasis can be performed. I can.

One end of the second compression band 120 coupled to the coupling hole 142 of the fixing strap 140 as described above can be adjusted to allow length adjustment at the coupling portion, which is applied to a bag, belt, etc. Since it is disclosed in various ways, a detailed description will be omitted.

The QR lever (quick release lever) member 200 is for pressing and fixing the compression band member 100, and may include a second bevel gear 210, a fixed shaft rod 220, an adjustment lever 230, and the like. have.

Here, the second bevel gear 210 penetrates the first compression band 110 and is engaged with the first bevel gear 130, and a spiral protrusion and a helical groove are formed on the outer peripheral surface of the downward conical body, and the helical protrusion is By engaging and engaging the oblique groove 133 of the first bevel gear 130, when the second bevel gear 212 is horizontally rotated clockwise (1 in FIG. 2D), the first bevel gear 130 is counterclockwise. The second compression band 120 meshed with the gear groove 121 in the first bevel gear 130 by rotating (2 in FIG. 2D) can be advanced inside the first compression band 110 (3 in FIG. 2D). have. Of course, when the second bevel gear 210 is horizontally rotated counterclockwise, the first bevel gear 130 rotates clockwise so that the second compression band 120 moves backward from the inside of the first compression band 110. can do.

Further, the fixed shaft rod 220 is coupled to the upper end of the second bevel gear 210, and may be fixedly coupled horizontally to be perpendicular to the upper end of the second bevel gear 210.

In addition, the adjustment lever 230 is rotatably coupled to both ends of the fixed shaft rod 220 while having eccentricity, and the pressure roll 231 in the form of a roll is rotatably coupled to both ends of the fixed shaft rod 220 While the rotation center axis of the fixed shaft rod 220 may be provided to have an eccentricity skewed downward in the initial state not fixed, and a lever plate for easy rotation and rotation of the adjustment lever 230 on the pressure roll 231 232 may be formed to extend.

A discoloration sticker (S) is attached to the surface of the adjustment lever 230 as described above, and a recording area (W) for recording the hemostasis date and time may be provided adjacent to the attached discoloration sticker. Is a sticker that changes color when a certain period of time (for example, 2 hours, etc.) has elapsed, and the date and time of hemostasis is indicated in the recording area (W) at the time that the bleeding is stopped while the color is attached to the adjustment lever 230 together with a color change prevention sticker. When the discoloration prevention sticker is removed while writing, the discoloration sticker S is discolored over time, thereby providing a criterion for determining the patient's urgency so that treatment can be smoothly performed in an emergency situation.

When the fixed shaft rod 220 is coupled to the inner surface of the pressure roll 231 of the adjustment lever 230 so as to have a downward eccentricity, the outer peripheral surface of the pressure roll 231 and the surface of the first compression band 110 are spaced at regular intervals. When the fixed shaft rod 220 is rotated so that the upper and lower surfaces of the adjustment lever 230 are reversed in a state spaced apart by a distance, the outer circumferential surface of the pressing roll 231 contacts and presses the surface of the first compression band 110, The tourniquet can be stably and firmly fixed in the hemostatic state.

In the tourniquet as described above, after the first compression band 110 and the second compression band 120 are coupled through the fixing scrap 140 to first press the bleeding area, the adjustment lever 230 is rotated horizontally.

And, when explaining the second compression process, as shown in Fig. 2d, when additional compression on the bleeding area is required, the first compression when the adjustment lever 230 is rotated (1) horizontally in a clockwise direction. The second bevel gear 210, which is provided to penetrate the inside and outside of the band 110 and engages with the first bevel gear 130, is rotated, and according to the rotation, the second bevel gear 210 is rotated into the gear groove 121 of the second compression band 120. The first bevel gear 130 engaged is rotated in a counterclockwise direction (2) with respect to the longitudinal central axis, and engaged through the gear groove 121 according to the clockwise rotation of the first bevel gear 130 to press the second As the band 120 is advanced (3) inside the first compression band 110, the second compression band 110 and the second compression band 120 are adjusted to the total length (ie, decrease the length). You can press.

On the other hand, if it is necessary to loosen the tourniquet, the first bevel gear 130 is centered in the longitudinal direction according to the counterclockwise rotation of the second bevel gear 210 when the adjustment lever 230 is horizontally rotated counterclockwise. The second compression band 120 is rotated clockwise based on the axis and is engaged through the gear groove 121 according to the clockwise rotation of the first bevel gear 130 so that the second compression band 120 moves backward from the inside of the first compression band 110. , The total length of the first compression band 110 and the second compression band 120 may be increased and adjusted to a loose state.

In addition, the tourniquet as described above presses the first compression band 110 through the pressure roll 231 of the adjustment lever 230 according to eccentricity when the adjustment lever 230 is rotated along the fixed shaft rod 220 It can be fixed in a way that

For example, when explaining the process of fixing the tourniquet, the first compression by the combination of the fixing strap 140 and the secondary compression through the horizontal rotation of the adjustment lever 230 are completed, and this compression state (that is, the hemostatic state ) When it is necessary to rotate the adjustment lever 230, which is rotatably coupled to the fixed shaft rod 220, based on the longitudinal central axis of the fixed shaft rod 220, and the fixed shaft rod 220 is an adjustment lever. Since the upper and lower portions are reversed while being eccentric downward between the pressure rolls 231 of 230, the surface of the pressure roll 231 of the adjustment lever 230 may press the first pressure band 110 according to the eccentricity. In addition, by pressing the upper and lower surfaces of the first compression band 110 through the second bevel gear 210 that penetrates the first compression band 110 and meshes with the first bevel gear 130, it can be stably and firmly fixed. I can.

That is, when the fixed shaft rod 220 is eccentric downward between the pressure rolls 231 of the adjustment lever 230, the outer circumferential surface of the pressure roll 231 and the surface of the first pressure band 110 have a predetermined interval. However, when the adjustment lever 230 is rotated, the outer circumferential surface of the pressure roll 231 is changed to a state in which the outer peripheral surface of the pressure roll 231 is in contact with the surface of the first pressure band 110 and is pressed. Can be maintained.

Accordingly, the present invention can provide a quick and efficient hemostatic effect by fixing the compression band through rotation of the QR lever in a state where the compression band mounted on the bleeding portion is pressed by the desired compression strength through rotation of the QR lever.

In addition, in the present invention, when the adjustment lever provided on the QR lever member is rotated horizontally, the first bevel gear provided on the compression band member is rotated according to the rotation of the second bevel gear coupled to the adjustment lever, and the first bevel gear The length of the compression band is adjusted by being engaged through a gear groove formed in the compression band according to the rotation of, so that the bleeding area can be quickly and effectively pressed through a simple rotation operation of the adjustment lever.

In addition, in the present invention, when the adjustment lever is rotated along the fixed shaft rod, the bleeding portion is pressed by pressing the compression band through the pressing roll of the adjustment lever according to the eccentricity of the fixed shaft rod and the second bevel gear. In the state, it can be fixed quickly and effectively through a simple rotation operation of the adjustment lever to maintain the compressed state.
