Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical auxiliary devices, in particular to a thoracic surgery drainage tube fixing device facilitating patient movement. BACKGROUND

[0002] Chest drainage is a medical technology based on the anatomical structure of the pleural cavity. By connecting a negative pressure device through the drainage tube, the accumulated gas and fluid in the pleural cavity can be discharged, the negative pressure state of the pleural cavity can be restored, and the lung can be re-expanded. The treatment purposes include maintaining the normal position of the mediastinum and timely discovering complications such as active bleeding. Clinical nursing involves key links such as catheter anti-slippage, drainage bottle position management, and respiratory function exercise. In the case of catheter slippage or rupture, emergency wound closure measures need to be taken.

[0003] When performing drainage in thoracic surgery, medical personnel insert a drainage tube (usually a soft tube) into the intercostal space of the patient, and then fix the drainage tube. For example, a thoracic surgery drainage tube fixing device is disclosed in Chinese Patent Publication No. CN115501449A, which includes a chest fixing belt, a fixing pad fixedly arranged in the middle of the chest fixing belt, a central hole opened in the center of the fixing pad, a slot opened in the upper part of the central hole, an upper sliding block slidingly arranged on the right side of the chest fixing belt, and a vertical rod fixedly arranged at the bottom end of the upper sliding block.

[0004] The drainage tube in the above-mentioned prior art may be pulled during actual use, which may cause the drainage tube to loosen greatly, and thus the depth of the drainage tube inserted into the intercostal space of the patient may become shallower, which may affect the drainage effect. SUMMARY

[0005] The purpose of the present application is to provide a thoracic surgery drainage tube fixing device facilitating patient movement to solve the problems raised in the background.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions:

[0007] A thoracic surgery drainage tube fixing device facilitating patient movement, comprising:

[0008] a restraint assembly;

[0009] a fixing portion connected to the restraint assembly;

[0010] a rotating column connected to the fixing portion in a universal manner, the rotating column being provided with a first tube passing hole in the form of a through hole;

[0011] a clamping portion integrally connected to one end of the rotating column away from the fixing portion, the outer diameter of the clamping portion decreasing from top to bottom, the inner cavity of the clamping portion being in communication with the first tube passing hole, and the periphery of the clamping portion being provided with a deformation seam penetrating the inner cavity of the clamping portion.

[0012] The swing driving member is provided on the rotating column and causes the clamping portion to generate elastic contraction deformation when the rotating column rotates around the rotating fulcrum with the fixed portion.

[0013] Through the above technical solution, the fixing part can be fixed to the chest and abdomen of the patient through the binding component, and the drainage tube is inserted into the patient's body through the first tube hole for drainage. When the drainage tube is pulled, it will drive the rotating column to rotate. When the rotating column rotates, it triggers the action of the swing driving member, so that the swing driving member drives the clamping part to produce elastic contraction deformation, so that the first tube hole can clamp the drainage tube, so that when the drainage tube is pulled, the first tube hole clamps the drainage tube, thereby avoiding the drainage tube being clamped by the clamping part when it is pulled (lateral pulling force), and avoiding the drainage tube from being loosened significantly, which affects the drainage effect.

[0014] Furthermore, the restraint assembly includes a chest strap and an abdominal strap, and the abdominal strap and the chest strap are connected by a strap.

[0015] Through the above technical solution, the chest strap and the abdomen strap can bind and fix the fixing part to the chest and abdomen of the patient, thereby facilitating the fixation of the drainage tube.

[0016] Furthermore, the two ends of the chest strap and the abdomen strap are respectively provided with a buckle and an inserting plate, and the inserting plate is used in conjunction with the buckle.

[0017] Through the above technical solution, the buckle and the plug plate are inserted and installed, so that the two ends of the chest strap and the abdomen strap can be connected together, thereby facilitating the installation of the chest strap and the abdomen strap on the patient's chest and abdomen.

[0018] Furthermore, a hollow ball head is fixedly connected to the end of the rotating column in an integral manner, and a spherical groove for the hollow ball head to engage is provided at the end of the fixing portion.

[0019] Through the above technical solution, the hollow ball head rotates in the spherical slot, thereby enabling the rotating column to be universally rotatably connected to the fixing part.

[0020] Furthermore, the swing driving member includes a sliding sleeve sleeved on the periphery of the rotating column, the sliding sleeve slides freely on the periphery of the rotating column, the sliding sleeve is fixedly sleeved with a first annular flange at one end facing the fixed part, the fixed part end is fixedly connected to a second annular flange, the first annular flange is fixedly connected to a plurality of sliding parts in an axial array, the sliding part is provided with a floating column at one end facing the second annular flange, the floating column is used in conjunction with the second annular flange, and the sliding sleeve is provided with a tapered hole used in conjunction with the clamping part.

[0021] By the technical scheme, when the drainage tube is pulled, the drainage tube swings the rotating column along the rotating pivot of the fixed part, and the swing causes the at least one floating column to press the second annular flange surface, so that the sliding sleeve is subjected to an action force in a direction away from the clamping part, and then the inner wall of the tapered hole of the sliding sleeve exerts a pressing force on the outer wall of the clamping part, and then the outer wall of the clamping part is subjected to a pressing force along the radial inner side of the outer wall, so that the clamping part is elastically deformed to contract, and the hole wall of the first pipe passing hole of the clamping part can clamp the drainage tube.

[0022] Further, one end of the floating column towards the second annular flange is rotatably embedded with a ball.

[0023] By the technical scheme, when the drainage tube is pulled, the drainage tube swings the rotating column along the rotating pivot of the fixed part, and the swing causes the at least one floating column to press the second annular flange surface, so that the sliding sleeve is subjected to an action force in a direction away from the clamping part, and then the inner wall of the tapered hole of the sliding sleeve exerts a pressing force on the outer wall of the clamping part, and then the outer wall of the clamping part is subjected to a pressing force along the radial inner side of the outer wall, so that the clamping part is elastically deformed to contract, and the hole wall of the first pipe passing hole of the clamping part can clamp the drainage tube.

[0024] Further, one end of the floating column towards the second annular flange is rotatably embedded with a ball.

[0025] By the technical scheme, when the drainage tube is pulled, the drainage tube swings the rotating column along the rotating pivot of the fixed part, and the swing causes the at least one floating column to press the second annular flange surface, so that the sliding sleeve is subjected to an action force in a direction away from the clamping part, and then the inner wall of the tapered hole of the sliding sleeve exerts a pressing force on the outer wall of the clamping part, and then the outer wall of the clamping part is subjected to a pressing force along the radial inner side of the outer wall, so that the clamping part is elastically deformed to contract, and the hole wall of the first pipe passing hole of the clamping part can clamp the drainage tube.

[0026] Further, the inflation assembly comprises a sliding plug fixedly sleeved with one end of the floating column penetrating into the sliding part, the floating column is freely slidable on the sliding part, the sliding part is provided with a sliding cavity for clamping the sliding plug, and the outer wall of the sliding part is provided with an air pipe.

[0027] By the technical scheme, when the drainage tube is pulled, the drainage tube swings the rotating column along the rotating pivot of the fixed part, and the swing causes the at least one floating column to press the second annular flange surface, so that the sliding sleeve is subjected to an action force in a direction away from the clamping part, and then the inner wall of the tapered hole of the sliding sleeve exerts a pressing force on the outer wall of the clamping part, and then the outer wall of the clamping part is subjected to a pressing force along the radial inner side of the outer wall, so that the clamping part is elastically deformed to contract, and the hole wall of the first pipe passing hole of the clamping part can clamp the drainage tube.

[0028] Further, the sliding cavity is provided with a spring, the spring elastically abuts against the sliding plug, and the sliding plug is given potential energy in a direction towards the second annular flange.

[0029] Through the above technical solution, the spring generates an elastic resisting force on the sliding plug, so that when the pulling force on the drainage tube is removed, the elastic potential energy of the spring is released, which drives the sliding plug to move toward the second annular flange and causes the floating column to move toward the outside of the sliding part, thereby causing the floating column to squeeze the second annular flange, so that the rotating column can automatically swing to the initial state.

[0030] Furthermore, the inner diameter of the installation cavity is larger than the inner diameter of the second pipe hole.

[0031] Through the above technical solution, the inner wall of the installation cavity is prevented from limiting the drainage tube, resulting in a smaller degree of squeezing of the drainage tube when the airbag is expanded, so that when the drainage tube is pulled, the airbag has poor anti-pulling effect on the drainage tube.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1. In the present invention, the fixing portion can be fixed to the chest and abdomen of the patient through the restraining assembly, and the drainage tube is inserted into the patient's body through the first tube-penetrating hole for drainage. When the drainage tube is pulled, the rotating column will be driven to rotate. When the rotating column rotates, the swing driving member is triggered to drive the clamping portion to produce elastic contraction deformation, so that the first tube-penetrating hole can clamp the drainage tube. When the drainage tube is pulled, the first tube-penetrating hole clamps the drainage tube, thereby preventing the clamping portion from clamping the drainage tube when the drainage tube is pulled (lateral pulling force), thereby preventing the drainage tube from becoming loose and affecting the drainage effect.

[0034] 2. In the present invention, when the drainage tube is pulled, the drainage tube causes the rotating column to swing along the rotation fulcrum of the fixed portion. During the swing, the corresponding at least one floating column exerts a compressive force on the surface of the second annular flange, causing the sliding sleeve to be subjected to a force moving away from the clamping portion. This in turn causes the inner wall of the tapered hole of the sliding sleeve to exert a compressive force on the outer wall of the clamping portion. This in turn causes the outer wall of the clamping portion to be subjected to a compressive force along its radially inner side, causing the clamping portion to produce elastic contraction deformation, so that the hole wall of the first tube through hole of the clamping portion can clamp the drainage tube.

[0035] 3. In the present invention, when the rotating column is pulled and swings in the drainage tube, the floating column will trigger the inflation component to inflate the airbag corresponding to the floating column, causing the volume of the airbag to expand, and then the airbag will squeeze the drainage tube, causing the drainage tube to be subjected to a force in the opposite direction of the pulling direction, thereby avoiding the drainage tube from bending and causing blockage.

DETAILED DESCRIPTION

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0049] See also Figures 1-11 The present invention provides a technical solution: a thoracic surgical drainage tube fixing device that is convenient for patients to move, including a restraining component, which includes a chest strap 3 and an abdominal strap 1. The abdominal strap 1 is connected to the chest strap 3 through a strap 2. The two ends of the strap 2 are sewn to the chest strap 3 and the abdominal strap 1 respectively. In addition, the chest strap 3 and the abdominal strap 1 are in the shape of a belt, and the two ends of the chest strap 3 and the abdominal strap 1 are respectively provided with a buckle 5 and a plug plate 4. The plug plate 4 can be inserted into the buckle 5, so that the two ends of the chest strap 3 can be connected together. Similarly, the abdominal strap The belt 1 is also inserted into the buckle 5 through the insert plate 4, so that the two ends of the abdominal belt 1 are connected together. When in use, the insert plate 4 is first pulled out from the buckle 5 to separate the chest belt 3 and the two ends of the abdominal belt 1. Then, the chest belt 3 and the abdominal belt 1 are wrapped around the patient's body, and the insert plates 4 and buckles 5 at both ends of the chest belt 3 and the abdominal belt 1 are inserted together, so that the chest belt 3 is tied to the patient's chest and the abdominal belt 1 is tied to the patient's abdomen, thereby completing the link of the chest belt 3 and the abdominal belt 1 being tied to the patient's body. The surface of the chest belt 3 is provided with an avoidance hole for the drainage tube 6 to pass freely:

[0050] The surface of the chest strap 3 is connected to the fixing part 7 by rivets or screws. The fixing part 7 is provided with a spherical slot on the end surface away from the chest strap 3. A hollow ball head 15 is rotatably embedded in the spherical slot. The periphery of the hollow ball head 15 is fixed with a rotating column 18, so that the rotating column 18 can be universally rotatably connected to the end of the fixing part 7. The end of the rotating column 18 away from the fixing part 7 is coaxially fixed with a clamping part 25. The clamping part 25 can be provided as an integral part connected to the rotating column 18. The outer diameter of the outer clamping portion 25 decreases from top to bottom. A first through-hole 20 is coaxially formed in the rotating column 18 and penetrates the clamping portion 25. The first through-hole 20 has the same diameter as the inner hole of the hollow ball head 15 and the two are internally interconnected. In addition, a deformation gap 23 is formed on the periphery of the clamping portion 25 and penetrates the clamping portion 25. When the clamping portion 25 is subjected to a compressive force along its radial inner side, the clamping portion 25 can produce elastic contraction deformation, thereby shrinking the first through-hole 20.

[0051] The periphery of the rotating column 18 is sleeved with a sliding sleeve 8 capable of freely sliding on the periphery of the rotating column 18, the sliding sleeve 8 is fixedly sleeved with a first annular flange 14 at one end towards the fixed part 7, the end of the fixed part 7 is fixedly connected with a second annular flange 9, the first annular flange 14 is fixedly connected with a plurality of sliding parts 10 in an array along the axial direction thereof, the sliding part 10 is provided with a floating column 16 at one end towards the second annular flange 9, the floating column 16 is rotatably embedded with a ball 17 at one end towards the second annular flange 9, the ball 17 on the floating column 16 is used in cooperation with the second annular flange 9, the sliding sleeve 8 is provided with a tapered hole 21 used in cooperation with the clamping part 25, when the sliding sleeve 8 moves away from the clamping part 25, the inner wall of the tapered hole 21 will generate a pressing force on the periphery of the clamping part 25, thereby making the clamping part 25 be pressed along the radial inner side thereof, so that the clamping part 25 generates elastic shrinkage deformation;

[0052] The end of the clamping part 25 away from the rotating column 18 is coaxially fixedly connected with an annular part 13, the deformation seam 23 extends to the periphery of the annular part 13, the annular part 13 is coaxially provided with a second pipe hole 22 penetrating through the first pipe hole 20, the inner cavity wall of the annular part 13 is provided with a plurality of installation cavities 26 corresponding to the positions of the floating columns 16, the installation cavities 26 are installed with air bags 12, the sliding part 10 is provided with an inflation assembly for inflating the air bag 12, when the rotating column 18 swings due to the pulling of the drainage tube 6, the floating column 16 will trigger the inflation assembly to act, so that the air bag 12 corresponding to the floating column 16 is inflated, so that the volume of the air bag 12 is expanded, thereby making the air bag 12 press the drainage tube 6, so that the drainage tube 6 is subjected to a force in the direction opposite to the pulling direction, avoiding the bending of the drainage tube 6 to cause the plugging phenomenon of the drainage tube 6;

[0053] Specifically, the inflation assembly includes a sliding plug 24 fixedly sleeved with the floating column 16 penetrating into the sliding part 10 at one end, the floating column 16 freely slides on the sliding part 10, the sliding part 10 is provided with a sliding cavity for clamping the sliding plug 24, the outer wall of the sliding part 10 is installed with an air pipe 11, one end of the air pipe 11 away from the sliding part 10 is connected with the air bag 12 in penetration, the sliding cavity is installed with a spring 19 elastically abutting against the sliding plug 24, and the spring 19 gives the sliding plug 24 a potential energy for moving towards the second annular flange 9, when the floating column 16 is pressed by the second annular flange 9, the floating column 16 will drive the sliding plug 24 to slide in the sliding cavity, thereby making the sliding plug 24 press the air in the sliding cavity, so that the air in the sliding cavity can enter the air bag 12 through the air pipe 11, so that the volume of the air bag 12 is expanded, in addition, the inner diameter of the installation cavity 26 is larger than the inner diameter of the second pipe hole 22, avoiding the inner wall of the installation cavity 26 to limit the drainage tube 6, causing the degree of pressing the drainage tube 6 by the air bag 12 to be smaller when the air bag 12 is expanded, so that the anti-pulling effect of the air bag 12 on the drainage tube 6 is not good when the drainage tube 6 is pulled.

[0054] Working principle of the present invention:

[0055] Pull out the inserting plate 4 from the buckle 5 to separate the ends of the chest strap 3 and the abdominal strap 1. Then, wrap them around the patient's body and insert the inserting plates 4 and buckles 5 at both ends of the chest strap 3 and the abdominal strap 1 together, so that the chest strap 3 is tied to the patient's chest and the abdominal strap 1 is tied to the patient's abdomen, thus completing the process of tying the chest strap 3 and the abdominal strap 1 to the patient's body.

[0056] The end of the drainage tube 6 is passed through between the multiple air bags 12. At this time, the squeezing force exerted by the air bags 12 on the drainage tube 6 is small and can be ignored. After passing through the multiple air bags 12, the end of the drainage tube 6 is passed through the second tube hole 22, and then through the first tube hole 20 to the avoidance hole of the chest strap 3, so that the end of the drainage tube 6 can extend out of the chest strap 3. The drainage tube 6 can then be inserted into the patient's body for drainage. After insertion, the drainage tube 6 can be fixed to the patient's skin by tape or sutures.

[0057] Since the drainage tube 6 is fixed to the patient's skin by means of tape or sutures, it is possible that the drainage tube 6 will become loose when it is pulled. Therefore, this embodiment improves the existing technology. Specifically, when the drainage tube 6 is subjected to a pulling force, which is mainly a lateral pulling force, the drainage tube 6 will bend in the direction of the pulling force, so that the drainage tube 6 generates a force on the rotating column 18, thereby causing the rotating column 18 to tilt and swing. When the rotating column 18 tilts and swings, the balls 17 at the ends of one or more floating columns 16 corresponding to the tilting and swinging direction of the rotating column 18 will generate an extrusion force on the end surface of the second annular flange 9, so that the floating column 16 drives the sliding plug 24 to slide upward;

[0058] When the sliding plug 24 slides upward in the sliding cavity, it squeezes the air in the sliding cavity, causing the air in the sliding cavity to be squeezed into the trachea 11 and then enter the corresponding airbag 12 from the trachea 11, causing the airbag 12 to expand in volume. After the volume of the airbag 12 expands, the squeezing force on the drainage tube 6 is greater than that of the other airbags 12, so that the portion of the drainage tube 6 corresponding to the end surface of the annular portion 13 is subjected to a squeezing force in the opposite direction of the pulling force, so that the drainage tube 6 does not bend in the direction of the pulling force, or even if it bends, the degree of bending of the drainage tube 6 is small. In addition, the spring 19 generates an elastic biasing force on the sliding plug 24. When the pulling force on the drainage tube 6 is released, the elastic potential energy of the spring 19 is released, driving the sliding plug 24 toward the second annular flange 9 and causing the floating column 16 to move toward the outside of the sliding portion 10, thereby causing the floating column 16 to squeeze the second annular flange 9, allowing the rotating column 18 to automatically swing to its initial state.

[0059] When the sliding plug 24 moves into place, the sliding sleeve 8 will move away from the fixing portion 7, so that the inner wall of the tapered hole 21 on the sliding sleeve 8 generates an extrusion force on the periphery of the clamping portion 25, causing the clamping portion 25 to produce elastic contraction deformation, thereby causing the second through-tube hole 22 to clamp the drainage tube 6, thereby preventing the drainage tube 6 from becoming loose when being pulled, which may cause the drainage tube 6 to be pulled out from the patient's body surface.
