Detailed Implementation

[0018] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] The following is for reference. Figures 1-8 A thoracic tube fixation device 10 according to an embodiment of the present invention is described.

[0020] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7As shown, the thoracic tube fixation device 10 according to a first aspect embodiment of the present invention includes: a wearing structure 20 for wearing on a human body; a housing 30 mounted on the wearing structure 20, the housing 30 defining an installation space 31 for a thoracic tube to pass through, the housing 30 having two shell sidewalls 32 opposite to and spaced apart along a first direction, each of the two shell sidewalls 32 forming a first through hole 321 for a thoracic tube to pass through; and a tube fixing structure 40 fixed within the installation space 31 and located between the two shell sidewalls 32, the tube fixing structure 40 being used for a thoracic tube to pass through. A tube fixing structure 40 is provided near one shell sidewall 32 and opposite to the first through hole 321 on the corresponding shell sidewall 32. A buffer structure 50 is provided in the installation space 31 and is located between the tube fixing structure 40 and another shell sidewall 32. The buffer structure 50 includes multiple movable plates 51, multiple clamping parts 52 and elastic parts 53. The multiple movable plates 51 are arranged in sequence along the first direction and are all movable along the first direction. Each movable plate 51 is provided with a clamping part 52 for clamping the thoracic tube. Any two adjacent movable plates 51 are connected to the same elastic part 53.

[0021] Among them, such as Figure 1 As shown, the wearable structure 20 has a wearable body 21 and a back plate 22. In one embodiment, the wearable body 21 has a medical elastic fabric 211, a hook and loop fastener 212, and a loop fastener 213. The medical elastic fabric 211 is fixedly connected to the back side of the back plate 22. The loop fastener 213 is connected to one outer wall of the medical elastic fabric 211, and the hook and loop fastener 212 is connected to the other inner wall of the medical elastic fabric 211. With the cooperation of the loop fastener 213 and the hook and loop fastener 212, the medical elastic fabric 211 can be easily attached to the patient's chest or limb. In another embodiment, the wearable body 21 is provided with a breathable mesh fabric, an adjustment buckle, and elastic straps. Elastic straps are symmetrically fixed to both sides of the back plate 22. One elastic strap has an adjustment buckle at its free end, and the surface of the other elastic strap has evenly distributed buckle holes adapted to the adjustment buckle. By adjusting the engagement of the buckle with different buckle holes, the tightness of the wearable body 21 can be flexibly adjusted to suit the waist or shoulder fixation needs of patients of different body types.

[0022] like Figure 1 As shown, in this application, the first direction is the Y direction, the second direction is the X direction, and the third direction is the Z direction. The outer shell 30 can be made of materials such as ABS resin and polycarbonate, and the outer shell 30 can be constructed as a rectangular box or an arc-shaped box. Exemplary embodiments, such as... Figure 4As shown, at least one first slider 35 can be connected to the side of the outer casing 30 facing the back plate 22, and at least one first slide rail 221 can be connected to the side of the back plate 22 facing the outer casing 30. The first slide rail 221 is fixedly connected to the back plate 22, and the first slider 35 is slidably mounted on the first slide rail 221 along the extending direction of the first slide rail 221. The first slider 35 and the first slide rail 221 are assembled in a one-to-one correspondence. With the cooperation of the first slider 35 and the first slide rail 221, it is convenient to assemble and disassemble the outer casing 30 and the back plate 22.

[0023] The shell sidewall 32 can be constructed as a rectangular plate or as an arc-shaped plate. The first through hole 321 can be formed in the shell sidewall 32 by drilling or other means. The first through hole 321 can be constructed as a circle or as an ellipse.

[0024] The pipe fixing structure 40 of this application is disposed near the side shell sidewall 32 of the chest wall. The movable plates 51 can be provided in two, three, four, or other quantities; this application uses four movable plates 51 as an example for illustration. As one embodiment, the buffer structure 50 includes a guide rod 55, which passes through each movable plate 51 along a first direction, and each movable plate 51 is movable relative to the guide rod 55 along the first direction. As another embodiment, the buffer structure 50 may include two concave slide rails extending along the first direction, and each movable plate 51 is equipped with a pair of miniature rollers corresponding to the slide rails. The sliding cooperation between the rollers and the slide rails achieves the effect of multiple movable plates 51 being arranged sequentially along the first direction and all movable along the first direction.

[0025] The clamping parts 52 can be configured in two, three, four, or other numbers. This application will use four clamping parts 52 as an example. As an example, one movable plate 51 is provided with one clamping part 52. As another example, one movable plate 51 is provided with multiple clamping parts 52. This application will use one movable plate 51 with one clamping part 52 as an example. As one embodiment, the clamping parts 52 on any two adjacent movable plates 51 are arranged along a first direction. As another embodiment, the clamping parts 52 on any two adjacent movable plates 51 are staggered along the first direction. This application will use the staggered arrangement of the clamping parts 52 on any two adjacent movable plates 51 along the first direction as an example.

[0026] The wearable structure 20 in this application can be appropriately adjusted according to the body shape of different patients, which helps to expand the fit range of the chest tube fixation device 10. The side shell 32 of the tube fixation structure 40 is set near the chest wall to firmly lock the puncture end of the chest tube, which helps to reduce the risk of the chest tube going deeper into the chest cavity or dislodging outward. This application takes the chest tube under tension as an example. When the chest tube is pulled, the movable plate 51 can slide along the first direction. The elastic part 53 can absorb the tension through elastic deformation, converting the instantaneous impact force into elastic potential energy. This helps to improve the positional stability of the end segment of the chest tube that matches the chest wall, which helps to reduce the mechanical stimulation of the pleura by the chest tube, thereby reducing the pain in the chest cavity. It also helps to reduce the risk of leakage and infection caused by the chest tube being damaged by tension.

[0027] According to the thoracic tube fixation device 10 of the first aspect of the invention, by providing a buffer structure 50, when the thoracic tube is pulled, the elastic part 53 connected to the adjacent movable plate 51 absorbs the tension through elastic deformation, and converts the instantaneous impact force into the elastic potential energy of the spring. This helps to reduce the mechanical stimulation of the thoracic tube on the pleura, thereby reducing the pain in the human chest cavity. It also helps to reduce the risk of leakage and infection caused by rupture of the thoracic tube due to traction.

[0028] According to some embodiments of the present invention, such as Figure 7 As shown, along the second direction, the elastic part 53 is located on one side of the movable plate 51, and the clamping part 52 is located on the other side of the movable plate 51. The elastic part 53 includes: a first elastic member 531 and two first fixing members 532. The two first fixing members 532 are respectively fixed to two adjacent movable plates 51. The first elastic member 531 is connected between the two corresponding first fixing members 532. The first direction and the second direction are perpendicular.

[0029] In one embodiment, the first elastic element 531 can be constructed as a spring. In another embodiment, the first elastic element 531 can be constructed as an elastic fabric strip. This application will describe the first elastic element 531 as a spring as an example.

[0030] The first fixing element 532 can be made of materials such as ABS resin or polycarbonate. The first fixing element 532 can be fixed to the movable plate 51 by fasteners such as bolts or clips, or it can be glued to the movable plate 51 with medical-grade epoxy resin adhesive. When the thoracic cavity tube is stretched, the first elastic element 531 between adjacent movable plates 51 will absorb the tension through elastic deformation, converting the instantaneous impact force into the elastic potential energy of the spring, which helps to reduce the mechanical stimulation of the tube on the pleura and chest wall tissues.

[0031] The elastic part 53 and the clamping part 52 are located on both sides of the movable plate 51, which helps to reduce the risk of wear on the outer wall of the chest tube or obstruction of deformation of the elastic part 53 due to contact friction between the chest tube and the elastic part 53 when the clamping part 52 clamps the chest tube. At the same time, it also helps to optimize the internal space layout of the chest tube fixation device 10 and improve the internal space utilization of the chest tube fixation device 10. The two first fixing members 532 are respectively fixed to the adjacent movable plates 51, which can provide precise positioning of the two ends of the first elastic member 531.

[0032] According to some embodiments of the present invention, such as Figure 7 As shown, the first fixing member 532 includes a first body 533 and a second body 534. The first body 533 is fixed to the corresponding movable plate 51, and the second body 534 is detachably disposed on the corresponding first body 533. The second body 534 is fixedly connected to the corresponding first elastic member 531.

[0033] As one example, the first body 533 can be fixed to the corresponding movable plate 51 with adhesive. As another example, the first body 533 can be fixed to the corresponding movable plate 51 with fasteners such as bolts and clips. As yet another example, the first body 533 and the corresponding movable plate 51 can be integrally formed. As one embodiment, the first body 533 defines a first groove 535, which is open in a second direction away from the corresponding movable plate 51. The second body 534 moves into or out of the first groove 535 through the open end of the first groove 535, and the first elastic member 531 passes through the second through hole 536. As another embodiment, a first strong magnet is embedded on the side of the first body 533 facing the second body 534, and a second strong magnet with opposite polarity is embedded on the side of the second body 534 facing the first body 533 at the position corresponding to the first strong magnet. The magnetic attraction between the first and second strong magnets achieves the effect of the second body 534 being detachably mounted on the corresponding first body 533.

[0034] The second body 534 can be fixedly connected to the corresponding first elastic element 531 by adhesive, and the second body 534 and the corresponding first elastic element 531 can be fixedly connected by snap-fit. The first body 533 is fixed to the movable plate 51, and the second body 534 is detachably connected to the first elastic element 531. When replacing, only the second body 534 needs to be removed to replace the first elastic element 531, which facilitates the replacement of the first elastic element 531, simplifies the replacement steps, reduces the replacement time, and improves the replacement efficiency. Medical staff can remove the damaged second body 534 and the first elastic element 531 and replace them with spare second body 534 and the first elastic element 531. The whole process is quick, which can reduce the risk of pleural tract traction and irritation, and poor drainage caused by prolonged damage to the second body 534 and the first elastic element 531. This helps to improve the safety and emergency response capability of the pleural tract fixation device 10 in clinical use.

[0035] According to some embodiments of the present invention, such as Figure 7 As shown, the first body 533 defines a first slide groove 535. Along the second direction, the first slide groove 535 is open in the direction away from the corresponding movable plate 51. Along the first direction, the first body 533 has a second through hole 536 formed on the groove sidewall facing another first fixing member 532. The second through hole 536 extends along the second direction to the end of the groove sidewall away from the corresponding movable plate 51. The second body 534 moves into or out of the first slide groove 535 through the open end of the first slide groove 535, and the first elastic member 531 passes through the second through hole 536.

[0036] The first slide groove 535 is open away from the movable plate 51 along the second direction, and the second body 534 can slide directly into the first slide groove 535 along the open end. This allows the second body 534 to be moved directly in or out through the open end of the first slide groove 535 without disassembling other parts, which is more conducive to simplifying the steps of installing or disassembling the second body 534. This is more conducive to shortening the time for replacing the first elastic element 531 or maintaining the second body 534, and makes the chest tube fixation device 10 suitable for scenarios that require rapid treatment, such as emergency and intensive care.

[0037] The second through hole 536 extends along the second direction to the end of the groove sidewall away from the corresponding movable plate 51, preventing the first elastic member 531 from interfering with the first body 533, which would prevent the second body 534 from being assembled into the first slide groove 535. This facilitates the movement of the second body 534 into or out of the first slide groove 535, thereby facilitating the assembly and disassembly of the second body 534 and the first body 533.

[0038] According to some embodiments of the present invention, such as Figure 5 , Figure 6As shown, along the second direction, multiple clamping parts 52 are located on the same side of the buffer structure 50, and the clamping parts 52 on any two adjacent movable plates 51 are staggered along the first direction, with the first direction and the second direction being perpendicular.

[0039] In this design, multiple clamping parts 52 are located on the same side of the buffer structure 50, and the clamping parts 52 on any two adjacent movable plates 51 are staggered along the first direction. This allows the thoracic tube to be distributed in a serpentine pattern within the thoracic tube fixation device 10. When the thoracic tube is pulled in the first direction, the tension is transmitted through the serpentine tube to the elastic parts 53 of all adjacent movable plates 51. Multiple first elastic elements 531 undergo elastic deformation simultaneously, which helps reduce the risk of local overload of a single first elastic element 531 and also helps prolong the tension transmission time, thereby further reducing the stimulation of the patient by the instantaneous impact force. The fact that all clamping parts 52 are on the same side of the movable plates 51 and that adjacent clamping parts 52 are staggered along the first direction helps optimize the internal spatial layout of the buffer structure 50 and also helps reduce the risk of interference between adjacent clamping parts 52.

[0040] According to some embodiments of the present invention, such as Figure 8 As shown, the clamping part 52 includes: a mounting frame 521, a second elastic member 522, and a clamping plate part 523. The mounting frame 521 is rotatably mounted on the corresponding movable plate 51 about a second direction. The mounting frame 521 has a first mounting plate 524 and two second mounting plates 525. The two second mounting plates 525 are arranged opposite each other and spaced apart. The first mounting plate 524 is connected between the two second mounting plates 525. The two second mounting plates 525 are located on the side of the first mounting plate 524 away from the corresponding movable plate 51. At least a portion of the clamping plate part 523... Located between two mounting plates, the clamping part 523 includes a first clamping plate 526 and two second clamping plates 527. The first clamping plate 526 and the two second clamping plates 527 together define a first clamping space 528 for the passage of the thoracic tube. The first clamping plate 526 is fixed to the first mounting plate 524. The two second clamping plates 527 are located between the two second mounting plates 525 and spaced apart along the arrangement direction of the two second mounting plates 525. A second elastic member 522 is connected between each second clamping plate 527 and the corresponding second mounting plate 525.

[0041] The mounting bracket 521 can be made of materials such as ABS resin or polycarbonate. The first mounting plate 524 can be constructed as a rectangular plate or an arc-shaped plate. The second mounting plate 525 can be constructed as a rectangular plate or an arc-shaped plate. The second elastic element 522 can be constructed as a spring. The first mounting plate 524 can be integrally formed with the two second mounting plates 525, or the first mounting plate 524 can be connected to the two second mounting plates 525 by adhesive. As one embodiment, part of the clamping plate portion 523 is located between the two mounting plates. As another embodiment, the entire structure of the clamping plate portion 523 is located between the two mounting plates.

[0042] The first clamping plate 526 can be constructed as a rectangular plate or an arc-shaped plate. The second clamping plate 527 can be constructed as a rectangular plate or an arc-shaped plate. This application uses the example of both the first clamping plate 526 and the second clamping plate 527 being constructed as arc-shaped plates for illustration. The first clamping plate 526 can be fixed to the first mounting plate 524 by fasteners such as bolts and clips, or it can be adhered to the first mounting plate 524 by medical-grade epoxy resin adhesive. Alternatively, the first clamping plate 526 can be integrally formed with the first mounting plate 524.

[0043] In an exemplary embodiment, a shaft 56 is fixedly connected to the side of the mounting bracket 521 facing the movable plate 51, and a bearing seat 57 is rotatably connected to the side of the shaft 56 facing the movable plate 51. The bearing seat 57 is used to connect with the movable plate 51. Both second mounting plates 525 have first through holes 529. A connecting rod 58 is slidably connected inside the first through hole 529. One end of the connecting rod 58 is connected to a second clamping plate 527, and the other end of the connecting rod 58 is connected to a second mounting plate 525. A second elastic element 522 is sleeved on the outside of the connecting rod 58. By moving the second clamping plates 527 on both sides, the thoracic tube can be easily inserted into the first clamping space 528 defined by the first clamping plate 526 and the second clamping plate 527, and the thoracic tube is clamped and fixed under the elastic action of the second elastic element 522. A first rubber pad 59 is connected to the inner wall of both the first clamping plate 526 and the second clamping plate 527, which helps to increase the friction between the clamping part 52 and the thoracic tube, thereby increasing the clamping stability of the thoracic tube.

[0044] Two second clamping plates 527 are connected to the second mounting plate 525 via second elastic members 522. When the diameter of the thoracic tube is large, the thoracic tube will squeeze the second clamping plates 527, causing the second elastic members 522 to compress and deform, thus expanding the first clamping space 528. When the diameter of the thoracic tube is small, the second elastic members 522 will rebound and push the second clamping plates 527, thus shrinking the first clamping space 528. This facilitates the adaptation of the thoracic tube fixing device 10 to thoracic tubes of different diameters. Each second clamping plate 527 and the corresponding second mounting plate 525 are connected by a second elastic member 522. The elastic force of the second elastic member 522 allows the second clamping plate 527 to conform to the curvature of the outer wall of the thoracic tube, which helps to maintain stable contact between the clamping part 52 and the thoracic tube, thereby reducing the risk of thoracic tube displacement.

[0045] The thoracic tube passes through the first clamping space 528 of multiple clamping parts 52 in sequence, so that the thoracic tube is distributed in a serpentine shape. When the thoracic tube is pulled, the first elastic element 531 of the elastic part 53 of the adjacent movable plate 51 will absorb the tension through elastic deformation, and convert the instantaneous impact force into the elastic potential energy of the spring, thereby helping to reduce the mechanical stimulation of the thoracic tube on the pleura and chest wall tissue.

[0046] The mounting bracket 521 can rotate in the second direction via the shaft 56 and bearing seat 57, which allows the clamping part 52 to adjust the clamping angle according to the serpentine direction of the thoracic tube, reducing the risk of excessive bending of the thoracic tube due to a fixed clamping angle. When inserting the clamping part 52 into the thoracic tube, medical staff can manually pry open the two second clamps 527, and the thoracic tube can be directly placed into the first clamping space 528. After releasing the two second clamps 527, the second elastic element 522 rebounds, completing the operation of fixing the thoracic tube to the clamping part 52. The same applies when removing the thoracic tube; simply pry open the second clamps 527 to remove the thoracic tube. This reduces the difficulty of inserting and removing the thoracic tube, thereby reducing the clinical operation difficulty of the thoracic tube fixation device 10.

[0047] According to some embodiments of the present invention, such as Figures 5-7 As shown, the buffer structure 50 also includes: a mounting frame 54 and a guide rod 55. The mounting frame 54 is installed in the mounting space 31. The guide rod 55 extends along a first direction and is fixed to the mounting frame 54. The guide rod 55 passes through each movable plate 51 along the first direction. Each movable plate 51 is movable relative to the guide rod 55 along the first direction.

[0048] In particular, exemplary embodiments, such as Figures 5-7As shown, along the first direction, at least one second slider 541 is connected to both sides of the mounting frame 54. A second slide rail 361 is fixed within the mounting space 31. The second slider 541 and the second slide rail 361 are fitted together in a one-to-one correspondence. The second slide rail 361 can be mounted on the mounting plate 36 of the outer shell 30, and a second slide rail 361 can also be provided on the corresponding side wall 32 of the shell. Along the first direction, one side of the second slide rail 361 is fixedly connected to the mounting plate 36, and the other side of the second slide rail 361 is fixedly connected to the corresponding side wall 32 of the outer shell 30. With the cooperation of the second slider 541 and the second slide rail 361, the mounting frame 54 can be easily removed. The guide rod 55 can be set to one, two, three, or other quantities. This application uses two guide rods 55 as an example for explanation. The guide rod 55 can be integrally formed with the mounting frame 54, and the guide rod 55 can be fixed to the mounting frame 54 by bolts, clips, or other fasteners.

[0049] The guide rod 55 is fixed to the mounting frame 54 along the first direction and passes through each movable plate 51. The guide rod 55 guides the movable plate 51, which helps to limit the movement of the movable plate 51 to only along the first direction. The guide rod 55 passes through the movable plate 51, allowing the force on the movable plate 51 to be transferred to the guide rod 55, which helps to distribute the force on the movable plate 51, thereby reducing the risk of overload on the elastic part 53 and extending the service life of the thoracic tube fixation device 10. The guide rod 55 passing through each movable plate 51 along the first direction allows the guide rod 55 to form a uniform sliding constraint on all movable plates 51, which helps to ensure that multiple movable plates 51 slide synchronously in the same direction when the thoracic tube is pulled.

[0050] According to some embodiments of the present invention, such as Figure 1 , Figure 3 , Figure 6 As shown, the outer shell 30 includes: a shell body 33 and a cover 34, which are arranged along a second direction. The shell body 33 is located between the wearable structure 20 and the cover 34. The cover 34 and the shell body 33 are detachably connected to define the installation space 31 together with the shell body 33. The buffer structure 50 is movably disposed within the shell body 33 along the second direction. The first direction and the second direction are perpendicular.

[0051] Among them, such as Figure 1As shown, the cover 34 includes a cover plate 341 and an observation window 342. The observation window 342 is provided on the cover plate 341 and can be a transparent structure. As an example, the observation window 342 is an acrylic transparent window. Along the first direction, a pair of snap-on plates 343 are connected to both sides of the cover 34. A retainer 331 is fixed on the outer surface of the shell body 33. The snap-on plates 343 and the retainer 331 are detachably snapped together, which facilitates the assembly and disassembly of the cover 34. In an exemplary embodiment, the buffer structure 50 is disposed within the installation space 31. Along the first direction, both sides of the mounting frame 54 are connected to second sliders 541. The second sliders 541 are slidably engaged with the second slide rail 361. Through the sliding engagement of the second sliders 541 and the second slide rail 361, the buffer structure 50 is movably disposed within the housing body 33 along the second direction. With the cooperation of the second sliders 541 and the second slide rail 361, it is convenient to remove the mounting frame 54 from the installation space 31, thereby facilitating the assembly and disassembly of the buffer structure 50.

[0052] The cover 34 is detachably connected to the shell body 33. Opening the cover 34 opens the installation space 31, facilitating operations such as inserting the thoracic tube into the clamping part 52 and adjusting the position of the buffer structure 50, thereby improving clinical operation efficiency. The buffer structure 50 is movably disposed within the shell body 33 along the second direction, allowing it to slide and be disassembled within the shell body 33 along the second direction. This facilitates the removal of the buffer structure 50 from the installation space 31, making it easier to replace the buffer structure 50.

[0053] According to some embodiments of the present invention, such as Figure 2 As shown, the pipe fixing structure 40 includes: a first fixing part 41 and a second fixing part 42. The first fixing part 41 and the second fixing part 42 are arranged opposite to each other along a second direction. The first fixing part 41 is fixed inside the shell body 33, and the second fixing part 42 is fixed to the surface of the cover 34 facing the shell body 33. When the cover 34 and the shell body 33 are connected, the first fixing part 41 and the second fixing part 42 define a second clamping space 43 for the thoracic tube to pass through.

[0054] In an exemplary embodiment, the inner walls of both the first fixing part 41 and the second fixing part 42 are provided with second rubber pads 44, which helps to increase the friction between the tube fixing structure 40 and the thoracic tube, thereby increasing the stability of the tube fixing structure 40 in fixing the thoracic tube. The first fixing part 41 can be connected to the shell body 33 through the first fixing plate 60, one side of the first fixing plate 60 is fixedly connected to the inner wall of the shell body 33. The side of the second fixing part 42 facing the cover 34 is fixedly connected to the cover 34 through the second fixing plate 70, one side of the second fixing plate 70 is fixedly connected to the inner wall of the cover 34. When the cover 34 is closed, with the cooperation of the first fixing part 41 and the second fixing part 42, it is convenient to clamp and fix the thoracic tube, firmly fixing the thoracic tube in the chest wall position near the puncture point, which helps to reduce the risk of accidental displacement of the front end of the thoracic tube when the patient moves.

[0055] The first fixing part 41 and the second fixing part 42 are respectively preset at corresponding positions on the shell body 33 and the cover 34. When the cover 34 is closed, the first fixing part 41 and the second fixing part 42 automatically fit together along the second direction to form a second clamping space 43, reducing the number of additional manual adjustments or locking of the thoracic tube, which helps to simplify the installation difficulty of the thoracic tube fixation device 10 and improves the clinical operation efficiency of medical staff. The tube fixation structure 40 is set near the puncture point. The second clamping space 43 formed by the first fixing part 41 and the second fixing part 42 can fix the thoracic tube near the puncture end, which is more conducive to reducing mechanical stimulation of the pleural tissue.

[0056] When the cover 34 is opened, the second clamping space 43 is fully open, making it convenient for medical staff to place the chest tube into the chest tube fixing device 10. When the cover 34 is closed, the tube fixing structure 40 automatically clamps and fixes the chest tube, eliminating the need for manual adjustment of the clamping tightness of the tube fixing structure 40, which helps to simplify the operation of the chest tube fixing device 10.

[0057] According to some embodiments of the present invention, such as Figure 1 , Figure 3 , Figure 4 As shown, the shell body 33 is movably disposed on the wearable structure 20 along a third direction, so that the shell body 33 and the wearable structure 20 are detachably connected, and the first direction, the second direction and the third direction are perpendicular to each other.

[0058] In an exemplary embodiment, at least one first slider 35 may be connected to the side of the shell body 33 facing the back plate 22, and at least one first slide rail 221 may be connected to the side of the back plate 22 facing the shell body 33. The first slide rail 221 is fixedly connected to the back plate 22, and the first slider 35 is slidably mounted on the first slide rail 221 along the extending direction of the first slide rail 221. The first slider 35 and the first slide rail 221 are fitted together in a one-to-one correspondence. With the cooperation of the first slider 35 and the first slide rail 221, the shell body 33 can be movably disposed on the wearable structure 20 along a third direction, so that the shell body 33 and the wearable structure 20 can be detachably connected.

[0059] The shell body 33 is movable along a third direction, which allows medical staff to adjust its position according to the location of the patient's thoracentesis puncture point. This helps align the insertion path of the chest tube with the puncture point and reduces the risk of bending or traction of the chest tube due to positional deviation. The shell body 33 can be easily disassembled / installed with the wearable structure 20 by moving along the third direction, reducing the use of tools and simplifying the disassembly / installation procedures. This allows medical staff to quickly remove the shell 30 for disinfection and maintenance, or to remove it when the patient no longer needs fixation, thus improving the ease of use of the chest tube fixation device 10.
