Description

Technical Field

[0001] This invention relates to the field of orthopedic postoperative care devices, specifically to an orthopedic postoperative care belt that combines drainage tube fixation and compression hemostasis functions. Background Technology

[0002] Orthopedic surgery, as a highly invasive treatment, requires postoperative wound bleeding control and drainage management as core aspects of nursing care, directly impacting the patient's recovery process and complication rate. Postoperative orthopedic patients often require two key nursing procedures simultaneously: first, draining wound exudate and blood through drainage tubes to maintain local tissue cleanliness and reduce the risk of infection; second, applying appropriate pressure to the surgical incision and surrounding area to achieve hemostasis and reduce hematoma formation, creating favorable conditions for tissue healing.

[0003] Currently in clinical practice, drainage tube fixation and compression hemostasis are mostly achieved using independent nursing devices. For drainage tube fixation, traditional methods often involve attaching the drainage tube to the patient's skin surface with medical tape or wrapping it with a simple dressing. These methods have significant drawbacks: the adhesiveness between the tape and skin is easily reduced by sweat and secretions, causing the drainage tube to easily shift or slip during patient movement. This not only interrupts the drainage process but may also cause pain due to traction on the wound, and even lead to secondary wound damage. Furthermore, long-term use of adhesive tape may cause allergic reactions, especially in patients with limited postoperative limb movement or poor skin integrity, further increasing the difficulty of care and patient discomfort. While some specialized drainage tube fixation devices used clinically have improved fixation stability, their function is limited, only achieving drainage tube positioning and failing to address hemostasis requirements.

[0004] In the process of applying pressure to stop bleeding, existing techniques typically employ methods such as sandbag compression, elastic bandage wrapping, or specialized compression pads. While sandbag compression is simple to perform, the pressure is difficult to control precisely. Insufficient pressure fails to achieve the desired hemostasis, while excessive pressure can lead to local tissue ischemia and circulatory disorders. Furthermore, sandbags are prone to displacement during limb movement, making it difficult to maintain a continuous and stable compression effect. Elastic bandage wrapping relies on the experience of medical staff to control the tightness, which is highly subjective. Different personnel may apply inconsistent pressure, and the wrapping force may compress the drainage tube, affecting drainage patency. Although specialized compression pads can provide relatively uniform pressure, they also lack a coordinated design with the drainage tube fixation device. When both are used simultaneously, they must be positioned and installed separately, which not only increases the nursing procedure steps but may also cause unstable fixation of the drainage tube or displacement of the compression position due to spatial interference between the devices, thereby increasing the risk of complications such as poor drainage, subcutaneous hematoma, and infection.

[0005] Furthermore, the separate use of drainage tube fixation and compression hemostasis devices significantly increases the burden on the patient's limbs. Post-orthopedic patients already have limited limb mobility, and wearing multiple independent devices further restricts their range of motion, affecting post-operative rehabilitation exercises. At the same time, interference between devices may also reduce the efficiency of nursing procedures, requiring medical staff to check and adjust the two types of devices separately, prolonging nursing time and increasing the workload. Summary of the Invention

[0006] The purpose of this invention is to provide an orthopedic postoperative care belt that combines the functions of drainage tube fixation and compression hemostasis, in order to solve the problem that the drainage tube fixation and compression hemostasis devices in the prior art significantly increase the burden on the patient's limbs when used separately.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an orthopedic postoperative care belt that combines drainage tube fixation and compression hemostasis functions, comprising two flexible base belts, wherein the flexible base belts are provided with a compression hemostasis component and a drainage tube fixation component, wherein the compression hemostasis component is used for compression hemostasis after orthopedic surgery, and the drainage tube fixation component is used for fixing the drainage tube after orthopedic surgery, and a locking buckle is installed at one end of the flexible base belt.

[0008] The compression hemostasis assembly includes a base, an adjustment seat fixedly connected to the top of the base, an internal thread inside the adjustment seat, and a screw inserted inside the adjustment seat so that the adjustment seat and the screw form a threaded engagement. The bottom end of the screw passes through the adjustment seat and extends to the bottom of the base. The screw is rotatably connected to the compression block through a rotating connector so that rotating the screw can drive the compression block to rise and fall in the vertical direction. A pressure sensor is installed on the bottom surface of the compression block.

[0009] The drainage tube fixing assembly includes multiple slots, which are symmetrically opened on the base. Clamping blocks are symmetrically engaged on the multiple slots. Multiple threaded locking seats are symmetrically installed on the clamping blocks on both sides. Connecting rods are threaded inside the threaded locking seats on both sides. Clamping clamps are fixedly connected to the top of the multiple connecting rods.

[0010] Furthermore, the locking buckle adopts a snap-on structure, including a fixed buckle body and a movable pin. The fixed buckle body has an anti-slip groove inside, and the movable pin has corresponding elastic locking teeth.

[0011] Furthermore, the base is installed between two flexible basebands, the locking buckle is used to lock and fix the two flexible basebands, the pressure block is horizontally arranged below the base, a display is installed on one side of the base, and control buttons are respectively provided on both sides of the display.

[0012] Furthermore, the display is electrically connected to a pressure sensor to display pressure data at the point where the compression block is pressing on the patient's body.

[0013] Furthermore, the adjustment seat is disposed between the two side slots, and the clamping blocks on both sides are disposed laterally on both sides of the adjustment seat.

[0014] Furthermore, the slots are formed on both sides of the base in a T-shape, which is used to flexibly adjust the installation position of the clamping block. The bottom of the clamping block is provided with a protrusion that matches the slot.

[0015] Furthermore, the bottom end of the connecting rod is provided with a thread, and the thread specification of the bottom end of the connecting rod matches the threaded locking seat, so that the height and angle of the clamp can be adjusted by rotating the connecting rod.

[0016] Furthermore, the clamp adopts a semi-circular arc structure, with an anti-slip rubber pad on the inner wall and a mesh anti-slip texture on the surface of the rubber pad.

[0017] Compared with existing technologies, the postoperative care belt for orthopedic patients provided by this invention, which combines drainage tube fixation and compression hemostasis, has the following advantages:

[0018] 1. By setting up a compression hemostasis component and a drainage tube fixation component, the drainage tube fixation component and the compression hemostasis component can be integrated on a flexible baseband during orthopedic postoperative care. This eliminates the need for multiple additional nursing devices, reduces the burden on the patient's limbs, and avoids mutual interference between the two components, thereby reducing the risk of drainage tube displacement and compression position deviation.

[0019] 2. By using the pressure regulating component and pressure sensor, the pressure can be quantitatively adjusted and monitored in real time. Medical staff can set a precise pressure value according to the patient's surgical area to ensure that the pressure block is always in contact with the surgical area, avoid pressure fluctuations caused by changes in body position, improve the hemostasis effect and protect local blood circulation.

[0020] 3. The drainage tube fixing assembly features a symmetrical T-shaped slot on the base, allowing the clamping block to be finely adjusted laterally along the slot to accommodate the spacing requirements of multiple drainage tubes. The threaded locking seat and fine-tooth connecting rod structure support 0-60mm height adjustment of the clamp and allow for adjustment of the clamp's horizontal angle via a 360° rotating connecting rod, ensuring the drainage tube always maintains a natural curved state and preventing bending and blockage. The terminal clamp uses a semi-circular soft PC clamp to effectively prevent tube displacement and slippage caused by patient movement. This design protects the outer wall of the drainage tube from rigid clamping damage and adapts to the drainage needs of different surgical sites such as limbs and trunk through multi-dimensional adjustment, ensuring continuous and reliable drainage function.

[0030] As attached Figure 1 To be continued Figure 5 As shown:

[0031] Example 1:

[0032] This invention provides an orthopedic postoperative care belt that combines drainage tube fixation and compression hemostasis functions. It includes two flexible base belts 1 (the flexible base belt 1 is made of medical-grade breathable elastic material, and its inner wall is provided with a skin-friendly antibacterial layer). The flexible base belt 1 is provided with a compression hemostasis component 2 and a drainage tube fixation component 3. The compression hemostasis component 2 is used for compression hemostasis after orthopedic surgery, and the drainage tube fixation component 3 is used for fixing the drainage tube after orthopedic surgery. A locking buckle 4 is installed at the end of one flexible base belt 1. The locking buckle 4 adopts a snap-on structure, including a fixed buckle body and a movable pin. The fixed buckle body is provided with anti-slip grooves inside, and the movable pin is provided with corresponding elastic teeth. The two work together to achieve quick locking and fine length adjustment. After locking, it is not easy to loosen.

[0033] Working principle:

[0034] Wearing and fixing: According to the size of the patient's orthopedic surgical site (such as limbs, trunk, etc.), wrap two flexible base bands 1 around the two sides of the patient's surgical area, align the compression hemostasis component 2 with the postoperative bleeding target point, and the drainage tube fixing component 3 with the drainage tube laying direction; insert the end of the flexible base band 1 without the locking buckle 4 into the fixing buckle body of the locking buckle 4, and achieve initial locking by the engagement of the elastic teeth on the movable pin with the anti-slip groove inside the fixing buckle body, and then finely adjust the wearing length by pulling the flexible base band 1 to ensure that the nursing band fits the patient's body without being too tight or loose. The cooperation structure of the elastic teeth and the anti-slip groove can effectively prevent loosening caused by the patient's movement after locking, and ensure the wearing stability;

[0035] Compression hemostasis and drainage tube fixation: After the flexible baseband 1 is put on and fixed, the compression hemostasis component 2 achieves continuous compression of the surgical wound through the pressure of its contact with the patient's body. The tension transmission of the flexible baseband 1 forms a uniform pressure force to prevent blood seepage from the wound site and achieve hemostasis. At the same time, the drainage tube after orthopedic surgery is placed in the preset fixation position of the drainage tube fixation component 3 (such as the adapter groove or clamping structure on the baseband surface). The posture of the drainage tube is fixed by the limiting effect of the component itself, which prevents the drainage tube from shifting, twisting or falling off due to the patient turning over or moving, and ensures that the drainage channel is unobstructed.

[0036] The entire process requires no complicated operation. The snap-lock buckle 4 enables quick wearing and length adjustment, adapting to the needs of patients of different body types. At the same time, it ensures the reliability of compression hemostasis and the stability of drainage tube fixation, simplifying the postoperative care process in orthopedics.

[0037] Example 2:

[0038] This embodiment is basically the same as the previous embodiment, except that the compression hemostasis component 2 includes a base 21 (the base 21 serves as the mounting foundation and force transmission carrier for the entire compression hemostasis component 2; it is integrally molded from medical-grade ABS engineering plastic, possessing lightweight, high strength, and disinfection resistance characteristics, and can repeatedly withstand postoperative care processes such as alcohol wiping and ultraviolet disinfection, meeting the requirements for clinical aseptic use. Its shape is designed as an arc-shaped structure adapted to the human body). The base 21 is installed between two flexible basebands 1, and the locking buckle 4 is used... Two flexible basebands 1 are locked and fixed. An adjusting seat 22 is fixedly connected to the top of the base 21. The adjusting seat 22 has an internal thread, and a screw 23 is inserted into the adjusting seat 22 so that the adjusting seat 22 and the screw 23 form a threaded engagement. The bottom end of the screw 23 passes through the adjusting seat 22 and extends to the bottom of the base 21. The screw 23 is rotatably connected to the compression block 24 (the compression block 24 is made of medical silicone and its inner wall has an arc-shaped contact surface that fits the surgical area) through a rotating connector, so that rotating the screw 23 can drive the compression. The compression block 24 moves vertically and is horizontally positioned below the base 21. A pressure sensor 25 is installed on the bottom surface of the compression block 24 (the pressure sensor 25 is a thin-film flexible sensor with a thickness of only 0.5mm, embedded in the groove at the bottom of the compression block 24, with the sensor surface flush with the arc-shaped contact surface of the compression block 24, ensuring that the detected pressure value is the actual force on the compression surface and avoiding pressure detection deviation caused by sensor protrusion). A display 26 is installed on one side of the base 21 (the display 26 is fixed to one side of the base 21 by an embedded installation method, with a shell made of medical-grade ABS material and a surface covered with scratch-resistant tempered glass. The display 26 uses an LCD screen and has a built-in rechargeable lithium battery with a capacity of ≥500mAh, a single charge lasting ≥72 hours, and also supports USB-C interface charging for convenient clinical replenishment). Control buttons are provided on both sides of the display 26. The display 26 is electrically connected to the pressure sensor 25 and is used to display the pressure data of the compression block 24 pressing on the patient's body.

[0039] Working principle: Through the coordinated action of the adjustable compression mechanism and the pressure monitoring system, precise and controllable compression hemostasis and basic fixation of the drainage tube are achieved. The specific working process is as follows:

[0040] Nursing band positioning and fixation: Wrap two flexible base bands 1 around the patient's surgical area, aligning the compression block 24 under the base 21 with the upper part of the postoperative bleeding wound, ensuring that the compression block 24 is centered and aligned with the upper part of the wound area; lock the two flexible base bands 1 with the locking buckle 4, and finely adjust the length of the base band according to the patient's body circumference, so that the base band fits the body but does not affect blood circulation, laying the foundation for subsequent compression adjustment;

[0041] Pressure adjustment: Medical staff can convert rotational motion into linear motion by rotating the screw 23 inside the adjusting seat 22 and utilizing the threaded connection between the screw 23 and the adjusting seat 22. Since the screw 23 is rotatably connected to the pressure block 24 through a rotating connector, the rotation of the screw 23 will not drive the pressure block 24 to rotate synchronously. It only drives the pressure block 24 to rise and fall smoothly in the vertical direction, so as to compress or depress the area above the wound. When the pressure block 24 contacts the patient's body and applies pressure, medical staff can initially adjust the pressure by rotating the screw 23 a certain number of times to meet the hemostasis pressure requirements of different wounds.

[0042] Pressure monitoring and feedback: The pressure sensor 25 at the bottom of the compression block 24 monitors the actual pressure value of the compression surface in real time and converts the pressure signal into an electrical signal, which is then transmitted to the display 26 on one side of the base 21. After receiving the signal, the display 26 presents the pressure data in digital form, making it convenient for medical staff to monitor the compression force in real time. Medical staff can start and stop the device and clear the data through the control buttons on both sides of the display 26. If the pressure value exceeds the preset safety range (for example, if it is too high, it may cause tissue damage, and if it is too low, it will not achieve the hemostasis effect), the height of the compression block 24 can be quickly adjusted by the fine-tuning screw 23 until the pressure data displayed on the display 26 is in the optimal hemostasis pressure range.

[0043] This working process achieves precise adjustment of the compression pressure through threaded transmission. Combined with the real-time feedback from the pressure sensor 25 and the display 26, it solves the problem of uncontrollable pressure in traditional compression hemostasis, improves the safety and effectiveness of hemostasis, and simplifies the operation process for medical staff.

[0044] Example 3:

[0045] This embodiment is basically the same as the previous embodiment, except that the drainage tube fixing assembly 3 includes multiple slots 31, which are symmetrically opened on the base 21. Clamping blocks 32 are symmetrically engaged on the multiple slots 31. The adjusting seat 22 is arranged between the two slots 31, and the clamping blocks 32 on both sides are arranged laterally on both sides of the adjusting seat 22. Multiple threaded locking seats 33 are symmetrically installed on the two clamping blocks 32. The threaded locking seats 33 on both sides are threadedly connected to the connecting rods 34. The top of the multiple connecting rods 34 is fixedly connected to the clamps 35. The bottom of the connecting rods 34 is threaded, and the thread specification of the bottom of the connecting rods 34 matches the threaded locking seat 33 so that rotating the connecting rods 34 can adjust the height and angle of the clamps 35. The clamps 35 adopt a semi-circular arc structure and are provided with anti-slip rubber pads on the inner wall. The surface of the rubber pads is provided with mesh anti-slip textures to increase the friction with the drainage tube and prevent the drainage tube from sliding.

[0046] Working principle: Based on the precise compression hemostasis and pressure monitoring functions of Example 2, this embodiment achieves multi-directional stable fixation of the drainage tube through an adjustable drainage tube fixing mechanism. The specific working process is as follows:

[0047] Drainage tube fixing mechanism debugging: First, according to the laying path and quantity of drainage tubes, clamping block 32 is fixed to base 21 by clamping through slot 31, and damping elastic pads are provided at both ends of clamping block 32 so that the installation position of clamping block 32 is adapted to the direction of drainage tube; since slot 31 is symmetrically opened and the position of clamping block 32 can be finely adjusted along slot 31, it can flexibly adapt to the fixing requirements of different quantities and directions of drainage tubes;

[0048] Drainage tube clamping and fixing: Place the drainage tube in the semi-circular groove of the clamp 35. According to the installation height and posture of the drainage tube, rotate the connecting rod 34. Utilize the threaded engagement between the connecting rod 34 and the threaded locking seat 33 to adjust the vertical height of the clamp 35 by rotating the connecting rod 34 forward or backward, so that the clamp 35 is completely in contact with the drainage tube. At the same time, adjust the horizontal angle of the clamp 35 by rotating the connecting rod 34 to ensure that the drainage tube maintains a natural curved state and avoids drainage obstruction due to excessive bending. The anti-slip rubber pad on the inner wall of the clamp 35 contacts the surface of the drainage tube. The mesh anti-slip texture on the rubber pad can significantly increase the friction. At the same time, the elastic properties of the rubber material can form a flexible clamp for the drainage tube, which not only prevents the drainage tube from sliding or shifting, but also avoids damage to the drainage tube caused by rigid clamping.

[0049] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
