Description

Technical Field

[0001] The invention relates to the technical field of drainage tube fixing, and in particular to a drainage tube fixer. Background Art

[0002] After chest surgery, it is crucial to fix the drainage tube to prevent it from shifting or falling off, affecting the drainage effect and the patient's recovery. Choosing a suitable fixator can ensure that the drainage tube remains stable during patient activities or daily care, and improve the fixation effect. The drainage tube fixator needs to have good breathability and comfort to reduce the patient's discomfort when wearing it. Using soft, skin-friendly materials to make the fixator can significantly improve the patient's comfort.

[0003] The invention patent with publication number CN109646787B discloses a drainage tube holder, comprising a fixed base, a fixed cover plate, a sponge pad, a foam board, a soft polyurethane foam pad, a pressure-sensitive adhesive layer and release paper; a guide groove is opened on one side of the sponge pad mounting hole, and the sponge pad is installed in the sponge pad mounting hole of the fixed base; a sponge board is glued and fixed to the lower part of the fixed base; a soft polyurethane foam pad is glued and fixed to the lower part of the sponge board, and a drainage tube guide hole and a guide groove are arranged on the soft polyurethane foam pad, a pressure-sensitive adhesive layer is arranged at the bottom of the soft polyurethane foam pad, and a release paper is arranged on the outside of the pressure-sensitive adhesive layer.

[0004] Although the above patent has certain beneficial effects, it uses an adhesive layer to fix the drainage tube at a single point, which is easily affected by external forces (such as patient activities, turning over, etc.) and may become loose or fall off. In addition, single-point fixation concentrates all pressure on one point, which may easily cause local skin to be under pressure for too long and cause problems such as pressure sores. Due to poor stability and concentrated pressure problems, single-point fixation often fails to achieve an ideal fixation effect, causing the drainage tube to shift or fall off, resulting in local tissue damage such as tearing and bleeding. Displacement may also cause complications such as pain and infection, because the displaced drainage tube may no longer remain sterile and may stimulate surrounding tissues, thereby making the device less usable. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcoming of poor practicability of the fixer in the prior art and to propose a drainage tube fixer.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a drainage tube fixer, comprising a fixing frame and an upper conduit, the end of the upper conduit is provided with a connecting port, and the connecting port is located above the fixing frame, the upper conduit passes through the fixing frame, and the end of the upper conduit away from the fixing frame is fixedly connected to the lower conduit through a pipe connector, and the lower conduit is located below the fixing frame, and the side wall of the fixing frame is provided with a medical fixing patch, and the medical fixing patch is used to fix the fixing frame to the end of the sternum above the xiphoid process of the human ribs, and the interior of the fixing frame is provided with an anti-pull component, and the side wall of the upper conduit is provided with a chest patch, and the chest patch is used to fix the upper conduit to the sternum in the middle of the human ribs.

[0007] Preferably, fixing grooves are respectively provided on the left and right sides of the fixing frame, and the two fixing grooves are respectively fixedly connected with the first rubber belts.

[0008] Preferably, the ends of the two first rubber bands away from the fixing frame are respectively fixedly connected with fixing buckles, a second rubber band is fixedly connected between the two fixing buckles, and both the first rubber band and the second rubber band are in a critical state of relaxation and tension.

[0009] Preferably, the two fixing buckles are symmetrically distributed on both sides of the fixing frame, and the side walls of the two fixing buckles are respectively provided with breathable stickers, which are used to fit the fixing buckles to the middle depression between the two ribs in the hypochondrium region of the human body.

[0010] Preferably, a positioning sleeve is provided on the side wall of the second rubber belt, the positioning sleeve is located at the center of the second rubber belt, and the lower guide tube passes through the positioning sleeve.

[0011] Preferably, an upper pipe sleeve is fixedly installed on the top of the fixing frame, and the upper conduit passes through the upper pipe sleeve.

[0012] Preferably, a lower pipe sleeve is fixedly installed on the bottom of the fixing frame, and the upper guide tube passes through the lower pipe sleeve.

[0013] Preferably, a medical ice bag is fixedly mounted on the bottom of the fixing frame, and the medical ice bag is in the shape of an arc rod.

[0014] Preferably, a sealing door is provided on a side of the fixing frame away from the medical fixing patch.

[0015] Preferably, the anti-pull assembly includes a rotating shaft, the rotating shaft is rotatably connected to the inner wall of the fixed frame, and the upper conduit is wrapped around the outer wall of the rotating shaft.

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] 1. In the present invention, a fixing frame, a medical fixing patch and an upper catheter are installed. The fixing frame is fixed to the end of the sternum above the xiphoid process of the human ribs by using the medical fixing patch, the upper catheter is fixed to the sternum in the middle of the ribs of the human body by using the chest patch, and the fixing buckle is fixed to the concave place of two ribs in the hypochondrium region of the human body by using the breathable patch. The shape of the breathable patch fits the concave area. These areas of the human body usually have stable bone support or rich muscle tissue, which can provide a stable fixing foundation for the upper catheter, effectively prevent the upper catheter from shifting or falling off, and further enhance the stability of the fixator. The two first rubber belts and the second rubber belt form a triangular structure to provide uniform supporting force in multiple directions, thereby ensuring that the fixing frame and the drainage tube maintain a relatively stable position during the daily activities of the human body to prevent shifting or falling off. The first rubber belt and the second rubber belt are normally in a critical state of relaxation and straightening, and the fixing force is dispersed to three points, avoiding excessive pressure concentrated in one place during single-point fixation, thereby reducing damage to the skin and making the device more practical.

[0018] 2. The present invention installs devices such as an upper tube sleeve, a rotating shaft and a lower tube sleeve, and the upper and lower ends of the upper catheter are fixed by the upper tube sleeve and the lower tube sleeve respectively, which effectively prevents the upper catheter from accidentally shifting or falling off during patient activities or daily care. When the lower catheter is pulled, the rotating shaft rotates flexibly and releases the upper catheter wrapped thereon, providing a buffer area for the upper catheter and the lower catheter, reducing the pulling force directly acting on the patient's body or wound, thereby protecting the wound and surrounding tissues. Through the buffering effect of the rotating shaft, even if the lower catheter is pulled by a large external force, these forces can be absorbed by gradually releasing the length of the upper catheter, thereby avoiding sudden and strong stimulation or injury to the patient.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Reference Figures 1 to 6 A drainage tube fixer comprises an upper catheter 3 and a fixing frame 6, wherein the fixing frame 6 is arranged at the end of the sternum above the xiphoid process of the human rib (refer to the human body model in the figure), where there is less fat accumulation, less skin tension, and the smallest range of motion, which can ensure that the fixing frame 6 remains relatively stable during various body activities and reduce the risk of displacement and falling off. The top of the fixing frame 6 is fixedly connected with an upper tube sleeve 5, and the bottom of the fixing frame 6 is fixedly connected with a lower tube sleeve 11. The interior of the fixing frame 6 is rotatably connected with a rotating shaft 8, and the upper catheter 3 penetrates the upper tube sleeve 5 and enters the interior of the fixing frame 6. The upper catheter 3 is coiled on the outer wall of the rotating shaft 8, and one end of the upper catheter 3 away from the upper tube sleeve 5 penetrates the lower tube sleeve 11, and one end of the upper catheter 3 away from the lower tube sleeve 11 is fixedly connected with a lower catheter 12 through a pipe connector 1. When the lower catheter 12 is pulled, the rotating shaft 8 rotates, allowing the upper catheter 3 to be pulled by itself when being pulled. The length can be adjusted dynamically to avoid the lower catheter 12 from breaking, and the patient's discomfort caused by external force is reduced. At the same time, due to the winding design of the upper catheter 3 on the rotating shaft 8, the fixation of the upper catheter 3 and the lower catheter 12 on the patient's body is more dispersed and uniform, reducing the pressure on the local skin and improving the patient's comfort. The end of the upper catheter 3 away from the lower catheter 12 is provided with a receiving port 2, and the receiving port 2 is located above the fixing frame 6. The side wall of the upper catheter 3 is provided with a chest patch 4, and the chest patch 4 is located on the side of the upper tube sleeve 5 close to the receiving port 2. The upper catheter 3 fits the sternum in the middle of the human ribs. The chest patch 4 fixes and positions the upper catheter 3, and uses the middle of the sternum as the fixing point of the upper catheter 3. Because its bone structure is hard and its position is relatively fixed, it can effectively reduce the displacement of the upper catheter 3 caused by chest movement (such as breathing) to ensure that the upper catheter 3 is unobstructed.

[0028] A medical fixing patch 9 is provided on the side wall of the fixing frame 6. The medical fixing patch 9 is torn off and the fixing frame 6 is attached to the end of the sternum above the xiphoid process of the human ribs. Fixing grooves 10 are respectively provided on the left and right sides of the fixing frame 6. The two fixing grooves 10 are respectively fixedly connected with a first rubber belt 14. The ends of the two first rubber belts 14 away from the fixing grooves 10 are respectively fixedly connected with fixing buckles 15. A second rubber belt 17 is fixedly connected between the two fixing buckles 15. The two first rubber belts 14 and the second rubber belt 17 are both in a critical state of relaxation and tension. A positioning sleeve 13 is provided on the side of the second rubber belt 17 close to the human body, and the positioning sleeve 13 is located at the midpoint of the second rubber belt 17. The end of the lower catheter 12 away from the fixing frame 6 passes through the positioning sleeve 13, and the lower catheter 12 is fixed to the second rubber belt 17 through the positioning sleeve 13, which effectively avoids large-scale shaking caused by patient activities or external factors, not only maintaining the stability of the lower catheter 12, but also reducing the discomfort or potential damage caused by shaking.

[0029] The two fixing buckles 15 are respectively provided with breathable stickers 16 on the side close to the human body. The breathable stickers 16 fit the fixing buckles 15 to the concave places of the two ribs in the hypochondrium region of the human body. The shape of the breathable stickers 16 fits the concave area of ​​the ribs of the human body. The breathable stickers 16 fit the concave places of the ribs in the hypochondrium region, which not only increases the contact area, but also utilizes the natural stability of the area, improves the firmness and comfort of the fixation, and the fixing frame 6, the two first rubber belts 14, the second rubber belt 17 and the fixing buckles 15 on both sides together form a stable triangular structure, which can provide uniformity in multiple directions. The supporting force ensures that the fixed frame 6 maintains a relatively stable position during daily human activities. The first rubber band 14 and the second rubber band 17 are normally in a critical state between a relaxed state and a stretched state, so that they can absorb and buffer the impact force generated by human movement like a spring, which helps to reduce direct impact on components such as the fixed frame 6, the upper conduit 3 and the lower conduit 12, extend their service life, and reduce the risk of damage caused by impact. The elastic connection also reduces the pressure and friction of the fixed frame 6 on the skin, reducing the risk of skin discomfort or damage caused by long-term wearing.

[0030] A sealing door 7 is provided on the side of the fixing frame 6 away from the medical fixing patch 9, and an arc-shaped medical ice bag 18 is provided at the bottom of the fixing frame 6. When the patient is in a lying or sitting position, the medical ice bag 18 will naturally fall on the fat layer on the abdomen, providing an additional support surface for the fixing frame 6. This support effect reduces the direct pressure of the fixing frame 6 on the skin. The cold compress effect of the medical ice bag 18 can reduce the sensitivity of the nerve endings of the local skin and subcutaneous tissue, thereby relieving mild pain and muscle tension caused by surgical trauma or other reasons. This soothing effect not only improves the patient's comfort, but also helps to promote postoperative recovery and reduce the patient's anxiety. The medical ice bag 18 as a support not only reduces skin pressure, but also indirectly enhances the stability of the fixing frame 6. This additional stability helps to maintain the accuracy of the fixed position and ensure the reliability of the treatment effect.

[0031] In the present invention, after a patient undergoes chest surgery, an external drainage tube is usually required for drainage. Now, there is an urgent need for a drainage tube fixer that has a good fixing effect and is comfortable and conforms to the human body structure. The device selects the most suitable fixing point for fixation according to the characteristics of the human chest structure, thereby improving the fixing effect and adding an anti-pulling function to improve safety.

[0032] In the human body, the end of the sternum above the xiphoid process of the ribs is selected as the center point of the fixator, where fat accumulation is less and skin tension is smaller, and no matter how the upper part of the human body moves, the movement range here is the smallest. Tear off the medical fixation patch 9, and fit the fixing frame 6 to the end of the sternum above the xiphoid process of the ribs of the human body, so as to achieve the best fixing effect.

[0033] The upper conduit 3 at the access port 2 is pulled down along the sternum in the middle of the human ribs, and the chest patch 4 is attached to the middle of the sternum to assist in positioning and fixing. The middle of the sternum is slightly concave compared to the muscles and fat tissues on both sides of the chest. The sternum is located in a relatively fixed position in the center of the chest, while the ribs have a relatively large range of movement when the human body is breathing or exercising. Attaching the upper conduit 3 here can reduce the displacement of the upper conduit 3 caused by the movement of the thorax to a certain extent, and the bone structure of the sternum is relatively hard, which can provide a certain support for the upper conduit 3, preventing the upper conduit 3 from being squeezed by the surrounding soft tissue and deformed or blocked.

[0034] The upper conduit 3 is inserted into the upper pipe sleeve 5 for basic fixation, and then inserted into the fixing frame 6. The sealing door 7 is opened, and the upper conduit 3 is wrapped around the rotating shaft 8 for two or three turns, and then passed through the lower pipe sleeve 11 to be connected with the lower conduit 12. The upper and lower ends of the upper conduit 3 are respectively fixed by the upper pipe sleeve 5 and the lower pipe sleeve 11. Under normal circumstances, the rotating shaft 8 will not rotate. When the lower conduit 12 is pulled, the rotating shaft 8 starts to rotate, and the upper conduit 3 wrapped around the rotating shaft 8 is pulled out to avoid breaking the lower conduit 12.

[0035] The fixing buckle 15 is attached to the concave area between the two ribs in the hypochondrium region of the human body using a breathable patch 16. The shape of the breathable patch 16 fits the concave area. The ribs in the hypochondrium region are also places where fat is less accumulated and skin tension is less, and the least deformation is caused by human breathing. The concave area of ​​the ribs in the hypochondrium region forms a natural "groove". The breathable patch 16 can better fit the curve of the body at this position, increasing the contact area between the breathable patch 16 and the skin, thereby improving the stability of fixation; when attached to the concave area, the breathable patch 16 can achieve good fixation in a relatively loose state. This is because the skin in the concave area is relatively flat, and the tape can be firmly attached without excessive stretching; in addition, during the patient's breathing, the muscles in the abdomen and chest will constantly contract and relax, and the ribs will move accordingly. The concave area is relatively stable, less affected by respiratory movements, and can better keep the position of the fixator unchanged.

[0036] The fixing frame 6 is connected through the fixing groove 10 and the first rubber belt 14 and the fixing buckles 15 on both sides. The fixing buckles 15 on both sides are connected through the second rubber belt 17. The first rubber belt 14 and the second rubber belt 17 are both in a critical state of relaxation and tension. The human body will produce various movements in daily activities, such as breathing, walking, body movements, etc. These movements will produce a certain impact force on the fixing frame 6. The elastic connection can absorb and buffer these impact forces like a spring, reducing the direct impact on the fixing frame 6, the upper conduit 3 and the lower conduit 12; forming a stable triangular structure, the fixing frame 6 can maintain a relatively stable position in all directions and is not easy to shift; when it is impacted or pulled by the outside world, the three-point fixation can disperse the external force and reduce the force on a single fixed point; the fixed force is dispersed to three points, avoiding the excessive pressure concentrated in one place when a single point is fixed, thereby reducing damage to the skin.

[0037] The lower tube 12 normally passes through the positioning sleeve 13 in the middle of the second rubber belt 17 to prevent the lower tube 12 from shaking significantly. When the patient is lying or sitting, the area below the sternum is very close to the fat layer on the belly. At this time, the arc-shaped medical ice pack 18 will normally fall on the fat on the belly, providing a support surface for the fixing frame 6, reducing the pressure on the skin, and bringing a slight cool feeling, which can reduce the sensitivity of the nerve endings of the local skin and subcutaneous tissue to a certain extent, and has a certain effect on relieving some mild pain and muscle tension caused by surgical trauma, thereby improving the comfort of the patient.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
