Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a drainage tube anti-bending and pressure fixing device. Background Technology

[0002] In spinal surgery and other medical fields involving back surgery, postoperative back wounds often require the placement of drainage tubes to drain accumulated blood and exudate, which is crucial for promoting wound healing and preventing infection.

[0003] However, when patients move, turn over, or perform daily activities, the drainage tube is often easily compressed, folded, or pulled, which not only affects the drainage effect but may also increase the patient's pain and the risk of complications. Therefore, a drainage tube anti-folding and compression fixation device is proposed to address the above problems. Utility Model Content

[0004] 1. The technical problem to be solved:

[0005] To address the aforementioned technical problems, this utility model provides a drainage tube anti-bending and pressure fixing device.

[0006] 2. Technical Solution:

[0007] A drainage tube anti-bending and fixing device includes a housing, which is composed of a bottom shell and a top shell. The lower end of the bottom shell is fixedly connected to an adhesive structure, and the upper end of the bottom shell is snapped into connection with the top shell. A negative pressure plate is provided between the bottom shell and the top shell. The lower end of the negative pressure plate is fixedly connected to a first drainage tube, and the front of the outer surface of the negative pressure plate is fixedly connected to a second drainage tube. The ends of the first drainage tube and the second drainage tube pass through the bottom and side of the housing, respectively.

[0008] With the bottom and top shells in place, the negative pressure plate and drainage tube can be supported and fixed by the bottom and top shells during use, which can prevent the drainage tube from bending during use.

[0009] Preferably, the adhesive structure includes a silicone pad, which is fixedly connected to the lower end of the base shell. An adhesive layer is applied to the lower end of the silicone pad, and release paper is adhered to the underside of the adhesive layer. By incorporating a silicone pad into the adhesive structure, the soft structure of the silicone pad allows the device to conform to the contours of the patient's back when it is attached and fixed, resulting in a more stable fixation.

[0010] Preferably, the bottom shell includes an annular shell, which is fixedly connected to the adhesive structure. The annular shell has slots on its upper left and upper right sides, and adjustment grooves are provided on the lower sides of the two slots at positions far apart from each other. The top shell includes a cover, and the cover has blocks fixedly connected on its lower left and lower right sides. The two blocks are respectively engaged with the two slots.

[0011] Preferably, a first groove is provided at the front of the upper end of the ring shell, a spring is fixedly connected to the inner surface of the first groove, a silicone layer is fixedly connected to the inner surface of the spring, and the spring is clamped and fixed to the second drainage tube through the silicone layer.

[0012] Preferably, a second groove is provided at the front of the lower end of the cover, and the second groove corresponds to the position of the first groove.

[0013] Preferably, the inner surface of the second groove is in contact with the outer surface of the spring.

[0014] 3. Beneficial effects:

[0015] 1. This utility model provides a drainage tube anti-bending and fixing device. By setting a bottom shell and a top shell in the device, and fixing an adhesive structure to the lower part of the bottom shell, when using the device, the negative pressure plate can be placed between the bottom shell and the top shell and fixed by the bottom shell and the top shell. Then, the first drainage tube is embedded in the tissue, and then the device is fixed to the patient's back by the adhesive structure. The support and protection of the bottom shell and the top shell can prevent the drainage tube from bending during use. At the same time, the setting of the silicone pad in the adhesive structure can make the adhesive structure fit better with the contour of the patient's back, making the device more stable.

[0016] 2. This utility model provides a drainage tube anti-bending and pressure fixing device. By setting a spring in the bottom shell and fixing a silicone layer inside the spring, when the negative pressure plate is placed between the bottom shell and the top shell, the second drainage tube in the negative pressure plate can be clamped and fixed by the spring. The silicone layer can play an anti-slip and limiting role, preventing the second drainage tube from moving freely during use, which would cause the connection between the negative pressure plate and the first drainage tube and the patient's skin to move and affect wound healing.

[0024] The present invention will now be described in detail with reference to the accompanying drawings.

[0025] As attached Figure 1 To be continued Figure 5 , Specific embodiment:

[0027] Please see Figure 1 and Figure 2 This utility model provides a drainage tube anti-bending and fixing device, including a housing, which is composed of a bottom shell 1 and a top shell 3. The lower end of the bottom shell 1 is fixedly connected to an adhesive structure 2, and the upper end of the bottom shell 1 is snapped to the top shell 3. A negative pressure plate 4 is provided between the bottom shell 1 and the top shell 3. The lower end of the negative pressure plate 4 is fixedly connected to a first drainage tube 5, and the front of the outer surface of the negative pressure plate 4 is fixedly connected to a second drainage tube 6. The ends of the first drainage tube 5 and the second drainage tube 6 pass through the bottom and side of the housing, respectively.

[0028] Further, such as Figure 3 As shown, the adhesive structure 2 includes a silicone pad 21, an adhesive layer 22 is applied to the lower end of the silicone pad 21, and release paper 23 is attached to the lower part of the adhesive layer 22. The silicone pad 21 is fixedly connected to the lower end of the bottom shell 1.

[0029] By incorporating a silicone pad 21 into the adhesive structure 2, the soft structure of the silicone pad 21 allows the device to conform to the contour of the patient's back when it is attached and fixed, thus making the device more secure.

[0030] Further, such as Figure 4 and Figure 5As shown, the bottom shell 1 includes an annular shell 11. The upper left and upper right sides of the annular shell 11 are provided with slots 12. The lower sides of the two slots 12 are provided with adjustment grooves 13 at positions far apart from each other. The upper front part of the annular shell 11 is provided with a first groove 14. A spring 15 is fixedly connected to the inner surface of the first groove 14. A silicone layer 16 is fixedly connected to the inner surface of the spring 15. The annular shell 11 is fixedly connected to the adhesive structure 2. The spring 15 is clamped and fixed to the second drainage tube 6 through the silicone layer 16. The top shell 3 includes a cover 31. The lower left and lower right sides of the cover 31 are fixedly connected with blocks 33. The lower front part of the cover 31 is provided with a second groove 32. The two blocks 33 are respectively engaged with the two slots 12. The second groove 32 corresponds to the position of the first groove 14, and the inner surface of the second groove 32 is in contact with the outer surface of the spring 15.

[0031] With the bottom shell 1 and top shell 3 in place, the negative pressure plate 4 and the drainage pipe can be supported and fixed by the bottom shell 1 and top shell 3 during use, which can prevent the drainage pipe from bending during use.

[0032] Working principle: This utility model provides a drainage tube anti-bending and fixing device, the core of which lies in the combined structural design, specifically composed of a bottom shell 1 and a top shell 3 that are interlocked together. At the same time, an adhesive structure 2 is integrated at the bottom of the bottom shell 1. In application, the negative pressure plate 4 is first securely placed between the bottom shell 1 and the top shell 3, and its fixation is achieved by the tight fit between the two shells. Then, the first drainage tube 5 is implanted into the tissue. Afterwards, the adhesive structure 2 is used to firmly attach the device to the patient's back. The double support design of the bottom shell 1 and the top shell 3 effectively prevents the bending phenomenon that may occur during the use of the drainage tube.

[0033] Of particular note is the silicone pad 21 embedded inside the adhesive structure 2, which has excellent flexibility and adaptability, and can closely conform to the complex contours of the patient's back, which not only improves the stability of the device but also enhances the patient's wearing comfort.

[0034] In addition, the bottom shell 1 is equipped with a spring 15 and its built-in silicone layer 16, which gently and firmly clamps the second drainage tube 6 in the negative pressure plate 4. The elasticity of the spring 15 ensures that the clamping force is appropriate and uniform, while the silicone layer 16 acts like a soft pad, which not only prevents the second drainage tube 6 from slipping accidentally, but also avoids the slight displacement of the connection between the negative pressure plate 4 and the skin caused by movement, thereby ensuring the best state of the wound healing environment.

[0035] Although the present invention has been disclosed above with reference to preferred embodiments, these are not intended to limit the present invention. Anyone skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope of protection of the claims of this application.
