Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a fixing device for preventing a drainage tube from falling off and a use method thereof. Background Art

[0002] In clinical medicine, stable fixation of drainage tubes is a key link in postoperative care and trauma treatment. In the prior art, common anti-falling devices mostly use a single strap combined with a local clamping structure to fix the drainage tube; other methods are to use tape to directly stick the drainage tube to the skin. This method is simple to operate, but frequent replacement of tape will cause pain to the patient; in addition, there is also a method of suturing the drainage tube to the skin with sutures, which is suitable for some special scenarios.

[0003] However, the existing technology has significant defects: the fixing device with a clamping mechanism usually only has a single fixing point, and the clamping force cannot be too large to squeeze the drainage tube, but it needs to keep the drainage tube fixed, so the operation is very troublesome. Specifically, it is difficult for a single fixed point to evenly disperse the external force on the drainage tube, and it is easy for the patient to fall off due to local concentrated force when moving. In order to enhance the fixation effect, the traditional device needs to compensate by increasing the clamping force or repeatedly adjusting the tightness of the strap, which may cause the drainage tube to be compressed and deformed, affecting the drainage efficiency. In actual operation, medical staff need to repeatedly weigh between "preventing falling off" and "avoiding excessive compression", which not only increases the complexity of the operation, but also requires frequent rework due to unstable fixation effect. This defect seriously restricts the application of existing devices in dynamic clinical scenarios.

[0004] Therefore, we propose a fixing device for preventing the drainage tube from falling off and a method of using the same, so as to solve the above-mentioned problems.

[0040] A method for using a fixing device for preventing a drainage tube from falling off, applied to a fixing device for preventing a drainage tube from falling off, comprises the following steps:

[0041] Installing the first and second straps on the patient's limb;

[0042] The drainage tube is fixed by a fixing mechanism;

[0043] The angle of the drainage tube is adjusted and fixed by the guide mechanism.

[0044] Compared with the prior art, the present invention has the following beneficial effects:

[0045] (1) The present invention fastens the first and second straps to the patient's limbs, clamps the drainage tube through the fixing mechanism and the guide mechanism, and after the drainage tube is led out of the patient's body, it is clamped by the fixing mechanism and the guide mechanism multiple times, and the guide mechanism changes the angle of the led-out drainage tube and keeps it fixed.

[0046] (2) The present invention significantly improves the stability of drainage tube fixation and clinical operation efficiency through the double-layer binding design of the first strap and the second strap, combined with the multi-level clamping effect of the fixing mechanism and the guiding mechanism. On this basis, the fixing mechanism and the guiding mechanism are also configured in a form that is convenient for adjustment. Specifically, the drainage tube is clamped by the elastic force of the spring and the torsion spring, and the clamping of the drainage tube is decomposed into multiple sections, thereby avoiding the problem of local compression and deformation caused by the traditional hard clamping slot.

[0047] (3) The present invention connects the vertical connecting strap and the second restraining strap by a third Velcro, which is not only simple to install and disassemble, but also convenient to adjust the angle of the vertical connecting strap. In particular, when the angle of the second restraining strap is incorrect during installation, or after being used for a long time, the second restraining strap rotates relative to the patient's limbs due to the movement of the patient's limbs, the angle of the vertical connecting strap can be adjusted at any time. In addition, when it is necessary to adjust the path of the drainage tube lead-out end, it is also convenient to adjust.

[0065] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. It should be pointed out that the drawings are schematic and not drawn to scale. For the sake of clarity and convenience in the figures, the relative sizes and proportions of the parts shown in the figures are exaggerated or reduced in size, and any size is only exemplary and not restrictive.

[0066] Embodiment 1:

[0067] See also Figure 1 A fixing device for preventing a drainage tube from falling off comprises: a first restraining belt 1, a connecting vertical belt 2, a second restraining belt 3, a fixing mechanism 4 and two sets of guiding mechanisms 6.

[0068] The fixing mechanism 4 is installed on the first restraining belt 1 and is used to fix the drainage tube; the second restraining belt 3 is connected to the first restraining belt 1 through the connecting vertical belt 2; and the guiding mechanism 6 is installed on the connecting vertical belt 2.

[0069] In the above technical solution, the fixing mechanism 4 is used to fix the end of the drainage tube extending outward from the patient's limb, and after being clamped by the fixing mechanism 4, the drainage tube is fixed by the guide mechanism 6. Through the cooperation of the fixing mechanism 4 and the guide mechanism 6, the force required to clamp the drainage tube is dispersed to different positions of the drainage tube, thereby stably clamping it, and the operation process is relatively convenient.

[0070] Another advantage of the above technical solution is that a certain redundant length can be reserved for the drainage tube between the fixing mechanism 4 and the guide mechanism 6, and between the guide mechanism 6 and the guide mechanism 6, that is, the shape between the fixing mechanism 4 and the guide mechanism 6 and between the guide mechanism 6 is an arc-shaped arch state, so as to avoid the drainage tube being directly involved in the patient's surgical position due to accidental involvement, thereby avoiding causing pain to the patient.

[0071] Please continue reading Figure 1 The first restraint belt 1 includes: a first fixing belt 11, with first tightening belts 12 fixedly installed at both ends; the first tightening belt 12 is passed through the fixing mechanism 4 and fixed to the first fixing belt 11 through a first Velcro 13.

[0072] By adopting the above technical solution, when in use, by pulling the first tightening belt 12, the area of ​​the closed structure composed of the first fixing belt 11, the first tightening belt 12 and the fixing mechanism 4 can be reduced, that is, the fixing mechanism 4 is locked on the patient's limb.

[0073] At the same time, two sets of first tightening belts 12 are designed to be located on both sides of the fixing mechanism 4. If the position of the fixing mechanism 4 deviates from the predetermined position during installation, the fixing mechanism 4 can have a certain lateral translation space by adjusting and retracting the first tightening belts 12 on both sides, thereby achieving the effect of easy adjustment.

[0074] See also Figure 1-Figure 3 The second restraining belt 3 includes: a second fixing belt 31, with a tail end 32 and a second tightening belt 33 fixedly installed at both ends; a concave buckle 35, fixedly installed on the tail end 32; the second tightening belt 33 passes through the concave buckle 35 and is fixed to the second fixing belt 31 through a second Velcro 34.

[0075] See also Figure 1 ,as well as Figure 4-Figure 6The fixing mechanism 4 includes: a fixing block 41, which is provided with a U-shaped groove 43; a paper buckle 42, which is fixedly mounted at both ends of the fixing block 41; a first tightening belt 12 is wound around the paper buckle 42; a clamping assembly 44, which is arranged in the U-shaped groove 43 and is used to fix the drainage tube; the clamping assembly 44 includes: a first clamping block 441 and a second clamping block 442, which are arranged in the U-shaped groove 43, and the first clamping block 441 and the second clamping block 442 have opposite sides that are semicircular surfaces, and the first clamping block 441 and the second clamping block 442 are provided with guide holes 443; the guide rod 444 is fixedly installed in the inner cavity of the fixed block 41 and inserted in the guide hole 443; the spring 445 is sleeved on the guide rod 444, and the two ends are fixed by the first clamping block 441 or the second clamping block 442 and the fixed block 41 respectively; the fixed block 41 is also provided with two groups of long grooves 45; the first clamping block 441 and the second clamping block 442 are fixedly installed with a push-pull rod 447 through a connecting column 446; the connecting column 446 is penetrated in the long groove 45.

[0076] By adopting the above technical solution, when in use, the drainage tube can be installed on the fixing mechanism 4 by controlling the clamping assembly 44. Specifically, during operation, the two push-pull rods 447 are first pulled to slide along the long groove 45, so that the distance between the first clamping block 441 and the second clamping block 442 increases, and the drainage tube can be put in. After the operator releases the push-pull rod 447, the first clamping block 441 and the second clamping block 442 clamp the drainage tube under the elastic force of the spring 445.

[0077] The above process is simple, convenient and easy to use.

[0078] See also Figure 7-Figure 8 The guide mechanism 6 includes: an arc bottom block 61, which is installed on the connecting vertical belt 2 and has a semicircular groove; a clamping arc plate 62, which has two groups and is rotatably connected to both sides of the arc bottom block 61 through a rotating shaft 63; a slot 64 is provided in the arc bottom block 61 and the clamping arc plate 62; a torsion spring 65 is sleeved on the rotating shaft 63; the two legs of the torsion spring 65 are inserted into the slots 64 of the arc bottom block 61 and the clamping arc plate 62.

[0079] When the above technical solution is used, it is first installed on the fixing mechanism 4, and then the drainage tube is placed on the upper side of the clamping arc plate 62 and pressed downward. The angle between the two clamping arc plates 62 increases, so that the drainage tube can enter smoothly. Then the clamping arc plate 62 is reset, and stable clamping is achieved under the action of the torsion spring 65.

[0080] See also Fig. 9 , shows one of the installation methods of the drainage tube. After being fixed by the fixing mechanism 4, the drainage tube directly changes its angle and is clamped on the guide mechanism 6. Through the multiple clamping mechanisms of the fixing mechanism 4 and the guide mechanism 6, it is ensured that the drainage tube is firmly clamped, and the local pressure is not too large, and the adjustment is simple.

[0081] See also Fig.10 , shows another installation method different from the above. After one end of the drainage tube is fixed by the fixing mechanism 4, it extends outward for a while and then clamped on the guide mechanism 6. This installation method reserves a certain amount of redundant space for the drainage tube to prevent the drainage tube from being directly pulled and displaced when it is accidentally involved, thereby improving safety.

[0082] Embodiment 2:

[0083] See also Figure 1 as well as Figure 4 and Figure 5 On the basis of Example 1, a connecting ring 7 is fixedly installed on the bottom end of the fixing block 41; the connecting vertical belt 2 is movably sleeved on the connecting ring 7; and the tail end 32 and the connecting vertical belt 2 are fixed by a third Velcro 5.

[0084] By adopting the above-mentioned technical scheme, the device is made more flexible in use. Not only is it easy to install and disassemble, but it is also convenient to adjust the angle of the connecting vertical strap 2. In particular, when the angle of the second restraint strap 3 is incorrect during installation, or after being used for a long time, the second restraint strap 3 rotates relative to the patient's limbs due to the movement of the patient's limbs, the angle of the connecting vertical strap 2 can be adjusted at any time. In addition, when it is necessary to adjust the path of the lead-out end of the drainage tube, it is also convenient to adjust.

[0085] Embodiment 3:

[0086] On the basis of Example 1, the arc-shaped bottom block 61 located on one side of the second fixing belt 31 is rotatably connected to the connecting vertical belt 2 to facilitate the operator to flexibly adjust the angle of the drainage tube.

[0091] Working principle: When in use, first tie the first tie belt 1 and the second tie belt 3 to the patient's limbs, and the fixing mechanism 4 is located near the drainage tube lead-out position, and the distance between the first tie belt 1 and the second tie belt 3 can keep the connecting vertical belt 2 fully unfolded. When in use, the operator installs the led-out drainage tube on the fixing mechanism 4 and the guide mechanism 6 in sequence, thereby completing the fixation of the drainage tube.
