Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Fig. 1 is a schematic structural view of a specific embodiment of the finger-root tourniquet disclosed in the present invention. As shown in the figure, the finger-root tourniquet 100 is in a non-closed ring shape, and mainly includes a tourniquet body 101. Tourniquet body 101 is the arc, and its arc angle is more than or equal to 270 degrees, and A marks the arc angle in figure 1. The tourniquet body 101 is formed with a first end 102 and a second end 103 extending in opposite directions at two ends thereof, and the first end 102 and the second end 103 are alternately arranged. As shown in fig. 2, when the tourniquet is used in an operation, the tourniquet on the base of a finger disclosed in this embodiment can be quickly and accurately fitted on the finger of a patient. In order to facilitate the adjustment of the diameter of the finger-root tourniquet by the doctor, a plurality of first adjustment units are arranged on the first end part 102, and a plurality of second adjustment units are arranged on the second end part 103. In the present embodiment, the first adjusting unit is a first step 104 as shown in the figure, and the second adjusting unit is a second step 105 as shown in the figure. The plurality of first step portions 104 and second step portions 105 are uniformly distributed along the extending direction of the first end portion 102 and the second end portion 103, respectively. The first step 104 protrudes from the outer surface 102-2 of the first end 102 in the radial direction of the tourniquet body 101, and the second step 105 protrudes from the inner surface 103-1 of the second end 103 in the radial direction of the tourniquet body 101. In a non-use state, a gap is formed between end faces of the first stepped portion 104 and the second stepped portion 105 extending in opposite directions. During operation, a doctor applies external force to two sides of the tourniquet body 101, for example, the external force stops being applied after the left side and the right side of the tourniquet body 101 are respectively kneaded by two fingers until the diameters of the tourniquet body 101 are adjusted to be suitable, the first step parts 104 extend into a gap formed between two adjacent second step parts 105, the second step parts 105 extend into a gap formed between the two adjacent first step parts 104, the first step parts 104 and the second step parts 105 are alternately arranged at intervals to limit relative movement of the first end part 102 and the second end part 103, and the finger-root tourniquet plays a role in hemostasis. When the operation is completed, the doctor only needs to slightly lift the second end 103, so that the plurality of first step parts 104 and the plurality of second step parts 105 are separated, and the finger root tourniquet can be conveniently taken down. The first step part 104 and the second step part 105 which are arranged at intervals can also only partially block blood flow, but not completely block blood flow, thereby being more in line with the actual needs of the operation.

in the present embodiment, the first step portion 104 and the second step portion 105 each have a smooth circular arc surface. As shown in fig. 1, the first step portion 104 and the second step portion 105 are both toothed, i.e., the cross-sectional area of the side close to the first end portion 102 and the second end portion 103 is larger than the cross-sectional area of the side far from the first end portion 102 and the second end portion 103. The edge of the end face of the toothed step part is smooth. When a doctor adjusts the tourniquet body 101 to a proper position, the gap with the smooth edge between any two first step portions 104 can guide the second step portion 105 at the opposite side to enter quickly and accurately, similarly, the gap with the smooth edge between any two second step portions 105 can also guide the first step portion 104 at the opposite side to enter quickly and accurately, and the diameter of the finger-root tourniquet can be adjusted to an ideal position in a short time. Moreover, the smooth end surface is not easy to scratch the skin. Even if the first stepped portion 104 and the second stepped portion 105 collide and contact at the time of kneading, since the end face of the toothed stepped portion is smooth rather than sharp, abrasion or breakage can be reduced, so that the use of the finger-root tourniquet is more stable.

In addition to the first step portion 104 and the second step portion 105 as the first adjusting unit and the second adjusting unit, a form in which the positioning protrusion 204 and the positioning through hole 205 are fitted may be adopted. Specifically, referring to fig. 3, the first adjusting unit is a positioning protrusion 204, and the positioning protrusion 204 protrudes from the outer surface of the first end portion 102 outward in the radial direction of the tourniquet body 101.

In a preferred manner, the positioning protrusions 204 and the positioning through holes 205 are uniformly spaced along the extending direction of the first end portion 102 and the second end portion 103, respectively. In the non-use state, the positioning boss 204 and the positioning through-hole 205 are in a separated state. During operation, a doctor applies external force to two sides of the tourniquet body 101, and the positioning protrusions 204 respectively extend into the corresponding positioning through holes 205 to limit relative movement of the first end portion 102 and the second end portion 103. Alternatively, the positioning protrusions 204 and the positioning through holes 205 are unevenly spaced along the extending direction of the first end portion 102 and the second end portion 103, respectively, so as to meet different adjustment requirements for the diameter.

Preferably, the outer portion of the finger-root tourniquet is provided with a bright color, such as yellow, etc., which is easy to find.

During treatment, doctors and patients may forget to loosen the finger-root tourniquet in time, which results in secondary injury caused by overlong wearing time of the finger-root tourniquet. To avoid this, as shown in fig. 4, a timing module 106 is further provided in the finger-root tourniquet disclosed in the present invention. The timing module 106 includes a button 107 and a timing chip (not shown). When the first adjusting unit and the second adjusting unit are matched and connected. The button 107 outputs a switch signal to the timing chip, and the timing chip receives the switch signal to start timing. Specifically, when the doctor adjusts the diameter, the button 107 can be pressed, and the button 107 outputs a switch signal to drive the timing chip to start timing. The timing chip can adopt a 555 timer or other similar integrated chips which can realize the timing function. The timing module 106 is further provided with a buzzer, and when the timing of the timing chip is finished, the buzzer outputs an alarm signal. Even the doctor can adjust the diameter of finger root tourniquet, avoid wearing the time overlength to appear necrotizing. The timing module 106 is preferably battery powered.

To facilitate the operation of the doctor, the timing module 106 is preferably disposed through the tourniquet body 101 and can slide along the tourniquet body 101 to adjust the position. The button 107 protrudes in the radial direction of the tourniquet body 101 away from the tourniquet body 101, and the timing button 107 can be pressed by a doctor after the diameter is adjusted.
