The drainage tube is located in the cavity formed by the first half ring wall 11 and the second half ring wall 12, which can avoid the slipping and displacement of the drainage tube.

[0040] In the embodiment shown in Figures 4-5 , Figures 8-10 , the first half ring wall 11 and the second half ring wall 12 can be enclosed to form a cylindrical shape.

[0041] In the embodiment shown in Figure 2In the illustrated embodiment, the first semi-annular wall 11 and the second semi-annular wall 12 are axially hinged. The side of the first semi-annular wall 11 and the second semi-annular wall 12 near the hinge is called the hinge side, and the side opposite to the hinge side is called the opening / closing side.

[0042] The clamping member receiving window 111 is provided with one or more, preferably two.

[0043] exist Figure 4 In the illustrated embodiment, the clamping member receiving window 111 matches the clamping portion 21. The first switching element 121 and the switching portion 22 are engaged by a snap-fit ​​mechanism.

[0044] exist Figure 4 In the illustrated embodiment, the first switching element 121 is a snap-fit ​​protrusion. The first switching element 121 can be located on the hinge side of the second semi-annular wall 12 or on the opening / closing side, depending on the configuration of the clamping member 2.

[0045] Furthermore, the first switching element 121 includes one or more snap-fit ​​protrusions. For example, there may be two, three, or four.

[0046] Furthermore, when the first switching element 121 is provided with multiple snap-fit ​​protrusions, the multiple snap-fit ​​protrusions are arranged parallel to each other circumferentially along the second semi-annular wall 12.

[0047] exist Figure 1 In the illustrated embodiment, the shape of the clamping part 21 is adapted to the inner cavity of the second semi-annular wall 12. That is, the shape of the clamping part is a semi-cylinder. This ensures that the flow of liquid and air is completely prevented when clamped.

[0048] Furthermore, the switch part 22 is an elastic band. The elastic band is provided with one or more snap-fit ​​holes. This ensures that the clamping device can match the different snap-fit ​​protrusions of the first switch element 121 when clamping drainage tubes of different diameters.

[0049] exist Figures 4-5 In the embodiment shown, the opening and closing direction of the clamping member 2 is consistent with the opening and closing direction of the first semi-annular wall 11 and the second semi-annular wall 12; Figures 8-10 In the embodiment shown, the opening and closing direction of the clamping member 2 is opposite to the opening and closing direction of the first semi-annular wall 11 and the second semi-annular wall 12.

[0050] exist Figures 4-5 In the embodiment shown, the opening and closing direction of the clamping member 2 is consistent with the opening and closing direction of the first semi-annular wall 11 and the second semi-annular wall 12. The clamping part 21 is hinged together with the first semi-annular wall 11 and the second semi-annular wall 12. The first switching element 121 is disposed on the opening and closing side of the second semi-annular wall 12.

[0051] exist Figures 8-10 In the illustrated embodiment, the opening and closing direction of part of the clamping member 2 is opposite to the opening and closing directions of the first semi-annular wall 11 and the second semi-annular wall 12. The short side of the clamping member receiving window 111 near the hinge point between the first semi-annular wall 11 and the second semi-annular wall 12 is designated as the first short side, and the other short side opposite the first short side is designated as the second short side. The clamping part 21 is hinged to the second short side of the clamping member receiving window 111, and the first switching element 121 is located on the hinge side of the second semi-annular wall 12. In this embodiment, the clamping member receiving window 111 does not extend to the edge of the first semi-annular wall 11; that is, the clamping member receiving window 111 must have a second short side to ensure that the first semi-annular wall 11 is a single unit.

[0052] The number of clamping members 2 matches the number of clamping member receiving windows 111. When multiple clamping members 2 are provided, the multiple clamping members 2 can be arranged in the same direction, such as... Figures 4-5 ; or you can set it in reverse, such as Figures 8-10 By setting multiple clamping elements 2 and the first switching element 121, it can be ensured that the drainage tube will not flow liquid when clamped.

[0053] exist Figure 8 , Figure 9 In the illustrated embodiment, the first semi-annular wall 11 or the second semi-annular wall 12 is further provided with a cooperating second switching element 3 and a third switching element 4. The second switching element 3 is disposed between the receiving windows 111 of each clamping member. The second switching element 3 is used to surround the first semi-annular wall 11 and the second semi-annular wall 12, thereby preventing accidental opening after the first semi-annular wall 11 and the second semi-annular wall 12 are closed.

[0054] exist Figure 1 In the embodiment shown, the second switching element 3 and the first semi-annular wall 11 are detachably connected or fixedly connected.

[0057] The third switching element 4 is a snap-fit ​​protrusion.

[0058] exist Figure 2 , Figure 3 In the enlarged view shown, the inner wall of the second semi-annular wall 12 and / or the side of the clamping part 21 that is used to cooperate with the cavity of the second semi-annular wall (12) is provided with anti-slip texture, which can increase the friction between the second semi-annular wall 12 and the drainage tube, and between the clamping part 21 and the drainage tube, so as to firmly fix the drainage tube.

[0059] In some embodiments, the body 1 and / or the clamp 2 are made of plastic, which is lighter in weight, reduces the effect of gravity, and improves patient comfort.

[0060] In some embodiments, the body 1 is made of transparent or translucent material, which facilitates the observation of the drainage fluid by medical staff.

[0061] In Figure 12 In the embodiment shown, the first semi-annular wall 11 or the second semi-annular wall 12 is provided with a fixing hole 13. The fixing hole 13 can be used to connect a rope or a fixing clamp (such as a stainless steel clamp, a dovetail clamp, etc.). The rope or the fixing clamp can be fixed to a third-party article, such as a patient's clothes, a bed sheet, a quilt cover, or a bed rail, so as to prevent the displacement or falling out of the drainage tube caused by the patient's movement.

[0062] In Figure 12 In the embodiment shown, a record card can also be connected to the fixing hole 13. The record card facilitates the medical staff to record the start and end time of the drainage.

[0063] The method for using the drainage tube clamping device of the present application is as follows:

[0064] The drainage tube is placed in the inner cavity of the second semi-annular wall 12, the first semi-annular wall 11 and the second semi-annular wall 12 are enclosed, the second switch element 3 and the third switch element 4 are buckled, and the first semi-annular wall 11 and the second semi-annular wall 12 are prevented from being accidentally opened. In order to prevent the displacement or falling of the drainage tube, the medical staff buckles the switch part 22 and the first switch element 121 according to the diameter of the drainage tube, so that the clamping part 21 contacts the drainage tube at the bottom but does not press the drainage tube, and the fixing clamp is fixed on the patient's clothes. When the patient needs to go out for examination or get out of bed, the patient or the medical staff re-buckles the switch part 22 and the first switch element 121, so that the bottom of the clamping part 21 contacts the inner wall of the second semi-annular wall 12, and the drainage tube is pressed. At this time, the clamping part 21 clamps the drainage tube, and cooperates with the anti-slip pattern on the inner wall of the second semi-annular wall 12 and the bottom of the clamping part 21 to better press the drainage tube.
