[0030] The following further describes in detail the embodiments of the present invention in conjunction with the drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0031] Embodiment 1

[0032] As shown in the attached Figure 1 to the attachedFigure 3 As shown, this embodiment provides a portable drainage tube holder, including a first fixing component 1, wherein the first fixing component 1 is used to install the holder on a bed sheet or a patient's clothes, the first fixing component 1 is connected to a connecting component 2, wherein the connecting component 2 makes the connection between the first fixing component 1, the second fixing component 4 and the hook 3 more flexible, thereby giving the patient a certain range of movement, the connecting component 2 is connected to the hook 3 and the second fixing component 4, wherein the hook 3 is used to prevent the drainage tube from detaching from the holder, the hook 3 is gourd-shaped, with a small upper end and a large lower end, and the drainage tube is located on the inner side of the hook 3, wherein the second fixing component 4 is used to install the holder on the guardrail of the bed, the first fixing component 1 and the second fixing component 4 cooperate to form a double anchor point, which can disperse the pulling force and prevent the holder from accidentally falling off when the patient moves;

[0033] The first fixing assembly 1 includes a clamping plate 101. The two clamping plates 101 are arranged opposite to each other. The clamping plates 101 are fixedly connected to a movable plate 102. The movable plate 102 is rotatably connected to a first connecting shaft 103. The first connecting shaft 103 is coaxially provided with a first torsion spring 104. By pressing the two clamping plates 101, the two clamping plates 101 rotate around the first connecting shaft 103 as the rotation axis. At this time, the first torsion spring 104 deforms and accumulates force, thereby controlling the opening and closing of the first fixing assembly 1.

[0034] The second fixing assembly 4 includes a first half ring 401 and a second half ring 402, and the first half ring 401 and the second half ring 402 are connected to a movable part 403, wherein the first half ring 401 and the second half ring 402 rotate around the movable part 403, and when the first half ring 401 and the second half ring 402 rotate, the movable part 403 accumulates energy to prepare for reset.

[0035] As can be seen from the above, the medical staff presses the two clamping plates 101 with their palms, causing the two clamping plates 101 to rotate with the first connecting shaft 103 as the rotation axis. At this time, the first torsion spring 104 deforms and accumulates force, and the first fixing component 1 opens. The medical staff can install the fixator on the bed sheet or the patient's clothes through the first fixing component 1. The medical staff pries the first half ring 401 and the second half ring 402 apart, and then puts the first half ring 401 and the second half ring 402 on the guardrail of the bed. The movable part 403 drives the first half ring 401 and the second half ring 402 to reset, thereby completing the installation. The medical staff presses the hook 3 to make a notch appear on the hook 3. At this time, the drainage tube can be placed in the hook 3 through the notch to prevent the drainage tube from detaching. The fixator is simple to operate, reduces the operation time and workload of the medical staff, and can also be operated by the patient himself.

[0036] Example 2

[0037] As attached Figure 1 To the attached Figure 4As shown, this embodiment is basically the same as the previous one. The difference is that both ends of the first connecting shaft 103 are connected with first anti - detachment plates 105. By setting the first anti - detachment plates 105, the separation of the first connecting shaft 103 from the movable plate 102 can be avoided. Both ends of the first torsion spring 104 are respectively abutted against the clamping plates 101, which can enable the first torsion spring 104 to better drive the two clamping plates 101 to reset.

[0038] Specifically, a groove 106 is provided at one end of the clamping plate 101, which provides a fixed point for finger pressing and can prevent the finger from slipping during pressing. A through - hole 107 is provided in the groove 106. When the finger is placed in the groove 106, the air in the groove 106 is discharged through the through - hole 107, avoiding unstable contact between the finger and the groove 106.

[0039] Furthermore, a rib 108 is provided at the other end of the clamping plate 101. The rib 108 increases the contact area between the anti - slip sleeve 109 and the clamping plate 101, thereby increasing the friction force and preventing the anti - slip sleeve 109 from falling off. An anti - slip sleeve 109 is sleeved on the end of the clamping plate 101 where the rib 108 is provided. Anti - slip patterns are provided on the side of the two anti - slip sleeves 109 that contacts the bedsheet or clothes, which can improve the clamping and fixing effect. The width of the end of the clamping plate 101 where the rib 108 is provided is greater than the width of the end of the clamping plate 101 where the groove 106 is provided, which can increase the contact area between the anti - slip sleeve 109 and the bedsheet or clothes.

[0040] Furthermore, the movable member 403 includes a first connecting plate 403a and a second connecting plate 403b. The first connecting plate 403a is connected to the first half - ring 401, and the second connecting plate 403b is connected to the second half - ring 402. A second connecting shaft 403c is rotatably connected between the first half - ring 401 and the second half - ring 402. A second torsion spring 403d is coaxially arranged on the second connecting shaft 403c. The first half - ring 401 and the second half - ring 402 open with the second connecting shaft 403c as the rotation axis, and when opening, the first torsion spring 104 deforms and stores energy.

[0041] Furthermore, both ends of the second connecting shaft 403c are connected with second anti - detachment plates 403e. By setting the second anti - detachment plates 403e, the separation of the second connecting shaft 403c from the first connecting plate 403a or the second connecting plate 403b is avoided. Both ends of the second torsion spring 403d are respectively abutted against the first half - ring 401 and the second half - ring 402, enabling the second torsion spring 403d to better drive the first half - ring 401 and the second half - ring 402 to reset.

[0042] Furthermore, the first half ring 401 is provided with a first protrusion 404 and a first limiting groove 405, and the second half ring 402 is provided with a second protrusion 406 and a second limiting groove 407. The shapes of the first protrusion 404 and the second limiting groove 407 are adapted to each other, and the shapes of the second protrusion 406 and the first limiting groove 405 are adapted to each other. When the first half ring 401 and the second half ring 402 are enclosed, they are slightly deformed so that the first protrusion 404 fits with the second limiting groove 407, and the second protrusion 406 fits with the first limiting groove 405. Through the mutual cooperation of the first protrusion 404, the second protrusion 406, the first limiting groove 405 and the second limiting groove 407, the first half ring 401 and the second half ring 402 can be prevented from being opened.

[0043] As can be seen from the above, the medical staff places their fingers in the groove 106 and presses the clamping plate 101. At this time, the first fixing component 1 opens, and the first torsion spring 104 deforms and accumulates energy. The opening of the first fixing component 1 is placed on the bed sheet or clothes, and the fingers are released. The first torsion spring 104 drives the two clamping plates 101 to reset, and then the anti-slip sleeve 109 bites the bed sheet or clothes. The medical staff pries the first half ring 401 and the second half ring 402 apart. At this time, the second torsion spring 403d deforms and accumulates energy, and the second fixing component 4 is put on the guardrail. The second torsion spring 403d drives the first half ring 401 and the second half ring 402 to reset, and makes the first protrusion 404 fit with the second limiting groove 407, and the second protrusion 406 fits with the first limiting groove 405, completing the installation of the fixator.

[0044] Example 3

[0045] As attached Figure 1 To the attached Figure 6 As shown, this embodiment is basically the same as the previous embodiment, with the difference that a gap is formed between the head end and the tail end of the hook 3, the head end of the hook 3 is provided with a first extension bar 5, the head end of the hook 3 and the first extension bar 5 cooperate to form a first blocking groove 6, the tail end of the hook 3 is provided with a second extension bar 7, the tail end of the hook 3 and the second extension bar 7 cooperate to form a second blocking groove 8, the first extension bar 5 is adapted to the shape of the second blocking groove 8, the second extension bar 7 is adapted to the shape of the first blocking groove 6, and the first extension bar 5 is abutted against the second blocking groove 8, and the second extension bar 7 is abutted against the first blocking groove 6, so that the drainage tube can be prevented from detaching from the hook 3 through the gap of the hook 3.

[0046] Specifically, the connecting component 2 includes a connecting seat 201, which is fixedly connected to the clamping plate 101. The connecting seat 201 is movably connected to the first chain link 202, and the first chain link 202 is movably connected to the second chain link 203. The first chain link 202 and the second chain link 203 cooperate to make the connection between the first fixing component 1, the second fixing component 4 and the hook 3 more flexible, so that the hook 3 can move freely, thereby facilitating the patient's movement.

[0047] Furthermore, the second link 203 is movably connected to a first hanging ring 9 and a second hanging ring 10. The first hanging ring 9 is fixedly connected to the hook 3, and the second hanging ring 10 is fixedly connected to the first half-ring 401. The first hanging ring 9 and the second hanging ring 10 make the movement of the hook 3 or the first half-ring 401 more flexible.

[0048] As can be seen from the above, the hook 3 has a certain elasticity. The medical staff applies an external force to the hook 3 by pressing the tail end of the hook 3. At this time, the hook 3 deforms and the notch expands. The drainage tube enters the hook 3 through the expanded notch. After the medical staff releases the hook 3, the hook 3 returns to its original state. At this time, the first extension strip 5 abuts against the second blocking groove 8, and the second extension strip 7 abuts against the first blocking groove 6, thereby preventing the drainage tube from detaching from the hook 3 through the notch of the hook 3. When the patient moves, the first link 202 and the second link 203 cooperate to make the hook 3 more flexible, so that the hook 3 can move freely, facilitating the patient's movement.
