Description

Technical Field

[0001] The utility model relates to the technical field of drainage tube fixers, in particular to a drainage tube fixer with strong adaptability. Background Art

[0002] Drainage tubes are used for clinical surgical drainage. They are a kind of medical device that guides pus, blood, and fluid accumulated between human tissues or in body cavities to the outside of the body to prevent postoperative infection and promote wound healing. Drainage tube fixators are a medical device used to fix drainage tubes. They can stably fix the drainage tubes in the patient's body to ensure that the position of the drainage tubes is accurate and stable. In clinical practice, drainage tube fixators are widely used in various surgical operations, trauma treatment, and intensive care to manage and remove fluids, blood, or secretions in the body.

[0003] Chinese patent publication number CN208823564U discloses a drainage tube fixer, including an adhesive tape, an adhesive sheet and a catheter clamping piece; the adhesive sheet is provided with an adhesive layer at the bottom and a catheter clamping piece in the middle; the catheter clamping piece includes a base and a clamping support sleeve, the clamping support sleeve runs through the middle of the base, and a notch is provided on one side of the adhesive tape, the base and the clamping support sleeve, so that the drainage tube to be fixed can pass through the notch and be fixed in the clamping support sleeve; the adhesive tape is multiple, the ends are fixedly connected to the base, and the side is provided with an adhesive layer, although the fixer can be fixed by passing the drainage tube to be fixed from the notch The catheter is passed through the opening and fixed inside the fixing support sleeve. The fixing support sleeve can support the insertion position to prevent the root of the drainage tube from bending. The adhesive sheet is attached to the puncture of the patient's drainage tube through adhesive, so that the positions of the drainage tube and the catheter clamp are adjusted appropriately. The adhesive tape is wrapped around the outer wall of the drainage tube through adhesive, which can effectively prevent the drainage tube from shifting or falling out. At the same time, it plays a certain reinforcement and support role to avoid affecting the fluidity of the liquid in the tube. However, most common fixers can only stably fix one drainage tube. When multiple sets of drainage tubes need to be fixed, multiple fixers are required, which is more troublesome, so it needs to be improved. Utility Model Content

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0025] Embodiment 1

[0026] See also Figure 1-6The utility model provides a technical solution: a drainage tube fixer with strong adaptability, comprising an adhesive layer 1, a breathable groove 11 is provided on the surface of the adhesive layer 1, which can improve the breathability and prevent the skin surface from becoming sticky. There are two groups of breathable grooves 11, and the two groups of breathable grooves 11 are symmetrically distributed on the surface of the adhesive layer 1. A fixing layer 2 is fixedly installed on the surface of the adhesive layer 1, and an arc groove 3 is provided on the surface of the fixing layer 2. The top and bottom ends of the arc groove 3 are provided with rounded corners 12, which are convenient for protecting the surface of the drainage tube and avoiding serious wear caused by friction between the surface of the drainage tube and the edge of the arc groove 3. The arc groove 3 and the positioning groove 10 are evenly spaced on the surface of the fixing layer 2, which is convenient for fixing multiple groups of drainage tubes. A rotating shaft 4 is fixedly installed on the surface of the fixing layer 2, and a groove 5 is provided on the surface of the rotating shaft 4. A positioning hoop 6 is rotatably connected inside the groove 5.

[0027] See also Figure 3-4 A positioning groove 10 is provided on the side of the positioning hoop 6 opposite to the arc groove 3. The positioning groove 10 is arc-shaped, which is convenient for clamping and fixing the drainage tube to prevent the drainage tube from being offset or bent. A latch 7 runs through the interior of the positioning hoop 6. A tension spring 8 is sleeved on the surface of the latch 7. One end of the tension spring 8 is fixedly connected to the surface of the pull plate 9, and the other end of the tension spring 8 is fixedly connected to the surface of the positioning hoop 6, so that the pull plate 9 can be automatically reset when the tension spring 8 is restored, thereby limiting the positioning hoop 6. A pull plate 9 is fixedly installed on one end of the latch 7.

[0028] Embodiment 2

[0029] See also Figure 5-6 A silicone block 13 is fixedly installed on the surface of the adhesive layer 1, a lift plate 14 is fixedly installed on the surface of the silicone block 13, and a fluorescent sticker 15 is fixedly installed on the surface of the lift plate 14, which is convenient for quickly locating the position of the adhesive layer 1, thereby facilitating the fixing and removal of the drainage tube. The fluorescent sticker 15 is fixedly connected to the lift plate 14 by a glue layer 16, which is convenient for fixing the fluorescent sticker 15.

[0030] Working principle: when in use, the adhesive layer 1 is attached to the surface of the patient's skin, and then the drainage tube is placed on the surface of the fixing layer 2, and the surface of the drainage tube is attached to the arc groove 3, and then the drainage tube can be fixed. When multiple sets of drainage tubes need to be fixed, the adhesive layer 1 is also first attached to the surface of the patient's skin, and then the multiple sets of drainage tubes are attached to the arc groove 3 in sequence, and then the positioning hoop 6 is rotated. The positioning hoop 6 rotates on the surface of the groove 5 at this time until the positioning hoop 6 is about to be perpendicular to the arc groove 3. At this time, the pull plate 9 is pulled outward, and the pull plate 9 drives the tension spring 8 to move outward. At the same time, the pull plate 9 drives the latch 7 to move outward, and then the positioning hoop 6 is rotated again to make the positioning hoop 6 perpendicular to the arc groove 3. At this time, the positioning groove 10 on the surface of the positioning hoop 6 is attached to the arc groove 3 and the surface of the drainage tube, and then the hand pulling the pull plate 9 is released, and the tension spring 8 loses the external force restriction. Due to its own tension, it drives the pull plate 9 to move inward, and the pull plate 9 simultaneously drives The movable latch 7 moves inward until the latch 7 passes through the positioning hoop 6 and is inserted into the surface of the fixed layer 2. At this time, the positioning hoop 6 can be fixed, and the positioning hoop 6 can fix multiple groups of drainage tubes. When the drainage tube needs to be removed, the pull plate 9 is manually pulled outward, and the pull plate 9 drives the tension spring 8 to move outward. At the same time, the pull plate 9 drives the latch 7 to disengage from the inside of the fixed layer 2 until the positioning hoop 6 is released from the restriction. At this time, the hand pulling the pull plate 9 is released. Due to the action of gravity, the positioning hoop 6 rotates on the surface of the groove 5 until the vertical state between the positioning hoop 6 and the arc groove 3 is released. At this time, the drainage tube can be taken out from the arc groove 3. When the adhesive layer 1 is removed from the skin surface, the fluorescent sticker 15 can help to quickly find the position of the adhesive layer 1, and then manually pull the lifting plate 14 upward. The lifting plate 14 drives the adhesive layer 1 to move upward until the adhesive layer 1 is lifted from the skin surface. At this time, the adhesive layer 1 can be removed by pulling it again.

[0031] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
