Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Reference Figures 1 to 4 The present invention discloses a tourniquet, comprising: a self-adhesive tape 1, one end of which is fixedly connected to a D-ring buckle 6, and a tightening mechanism provided on the self-adhesive tape 1, the tightening mechanism being close to the D-ring buckle 6;

[0027] Self-adhesive tape 1 is the self-adhesive tape used in existing rotary tourniquets.

[0028] The tightening mechanism includes a pressure component mounted on the self-adhesive tape 1, a tightening component connected to the pressure component, a self-locking structure inside the tightening component, a timer 18 mounted on the tightening component, and a marker 4 detachably connected to the tightening component.

[0029] Both a marker 4 and a timer 18 are set up. When the timer 18 malfunctions, the marker 4 can still be used to record the time. The presence of the marker 4 can also assist the tightening mechanism in rotating.

[0030] When using this utility model, first insert the end of the self-adhesive tape 1 away from the D-ring 6 into the D-ring 6, put the tourniquet on the appropriate position, and tighten and fix the self-adhesive tape 1. The tightening component drives the pressure component to tighten and pressurize the self-adhesive tape 1. When the pressure is appropriate, the tightening component is fixed by the self-locking structure. The initial time of hemostasis is recorded by the marker pen 4, and the timer 18 is started at the same time.

[0031] The tourniquet of this invention has a built-in timer 18 and a marker 4, which makes it convenient for users to record the hemostasis time and avoid situations where the hemostasis time is too short, resulting in poor hemostasis effect, or the hemostasis time is too long, resulting in limb damage or necrosis.

[0032] The scheme is further optimized. The tightening component includes a fixing plate 8, which is fixed to the self-adhesive tape 1 and close to the D-ring buckle 6. A screw cap 10 is provided on the fixing plate 8. A through hole 16 is coaxially opened on the screw cap 10. A fixing seat 13 is slidably connected in the through hole 16. The fixing seat 13 is coaxially arranged with the through hole 16 and is fixed to the fixing plate 8.

[0033] Further optimization of the scheme: the pressure component includes multiple tension straps 3, one end of each tension strap 3 is fixed to the outer wall of the swivel cap 10, the multiple tension straps 3 are located on both sides of the swivel cap 10, and the end of each tension strap 3 away from the swivel cap 10 is fixed to the tension strap 3 by a fixing strip 2.

[0034] Rotating the cap 10 causes the tensioning band 3 to wrap around the outer wall of the cap 10, thereby tightening and pressurizing the self-adhesive tape 1.

[0035] An outer ring 9 is fixedly connected to the fixing plate 8. The outer ring 9 is coaxially arranged with the rotating cap 10. Multiple through slots are provided on the outer ring 9. The tensioning band 3 passes through the through slots and is fixedly connected to the rotating cap 10. There is a gap between the inner side wall of the outer ring 9 and the outer side wall of the rotating cap 10, so that the tensioning band 3 can be wrapped around the rotating cap 10.

[0036] Further optimization of the scheme: the self-locking structure includes multiple slots 11, which are circumferentially and equally spaced on the outer side wall of the fixed base 13. The axis of the slot 11 is parallel to the axis of the fixed base 13. A plug 12 is slidably connected inside the slot 11 and is fixed to the inner wall of the through hole 16.

[0037] A bolt 14 is threaded onto the fixing seat 13. There is a gap between the nut of the bolt 14 and the top of the fixing seat 13. The gap is adapted to the insertion block 12. The top of the insertion block 12 abuts against the nut of the bolt 14.

[0038] When the cap 10 is lifted, the insert block 12 moves upward into the gap. At this time, the insert block 12 is disengaged from the slot 11, and the cap 10 can rotate freely. Pressing the cap 10 down causes the insert block 12 to be inserted into the slot 11, thus completing the self-locking.

[0039] In a further optimized design, a limiting ring 17 is circumferentially fixed to the inner wall of the through hole 16. The limiting ring 17 is located above the bolt 14, and the inner diameter of the limiting ring 17 is larger than the outer diameter of the nut of the bolt 14. A controller is fixed above the limiting ring 17. The controller is electrically connected to a timer 18 and an audible and visual alarm 20. Both the timer 18 and the audible and visual alarm 20 are located inside the through hole 16. The controller is electrically connected to a control button 19.

[0040] The control button 19, controller, timer 18 and audible and visual alarm 20 are existing technologies, and their connection methods can be selected by those skilled in the art according to their own needs. The timer 18 has a built-in time display function, and the controller is a single-chip microcontroller.

[0041] The timer 18 is controlled by the control button 19. When the set time is reached, the timer 18 transmits a signal to the controller, which then controls the audible and visual alarm 20 to sound an alarm, reminding the user that the set usage time has been reached.

[0042] The design is further optimized by fixing a connecting cap 5 to one side of the screw cap 10, and the marker 4 is detachably connected to the connecting cap 5.

[0043] The connection methods between the connecting cap 5 and the marker 4 include, but are not limited to, threaded connection, snap-fit ​​connection, etc. After the marker 4 is connected to the connecting cap 5, it can also be used as a lever to assist in rotating the cap 10.

[0044] In a further optimized design, a flexible protrusion 15 is fixedly attached to the side wall of slot 11. The purpose of setting the flexible protrusion 15 is to prevent the cap 10 from moving upwards when not needed, causing the tension band 3 to loosen.

[0045] Usage steps:

[0046] Insert the end of the self-adhesive tape 1 away from the D-ring 6 into the D-ring 6, put the tourniquet on the appropriate position, and tighten and fix the self-adhesive tape 1. Lift the cap 10 to move the insert 12 into the gap. At this time, the insert 12 is disengaged from the slot 11, and the cap 10 can rotate freely. The cap 10 drives the tensioning band 3 to wrap around the outer wall of the cap 10, thereby tightening and pressurizing the self-adhesive tape 1. When the pressure is appropriate, press the cap 10 down to move the insert 12 into the slot 11 to complete the self-locking. Then press the control button 19 to start the timer 18. At the same time, use the marker 4 to record the initial hemostasis time on the fixing strip 2. When the hemostasis time reaches the set value, the sound and light alarm 20 will sound an alarm to remind the staff that the hemostasis time has reached the set value.
