Description

Technical Field

[0001] This invention belongs to the field of medical nursing device technology, specifically relating to a system for zoning, angle guidance, mechanical torsion indication, and adjustment of traction damping of drainage tubes in the ventricles, lumbar cistern, wound cavity, and subdural area after brain surgery. Background Technology

[0002] Post-brain surgery patients often require multiple drainage tubes, including ventricular drainage tubes, lumbar cistern drainage tubes, wound cavity drainage tubes, and subdural drainage tubes. The following key technical deficiencies exist in clinical nursing care:

[0003] 1. The dense arrangement of multiple pipes, with small diameter and thin wall, makes them prone to crossing, tangling, and twisting, directly causing drainage blockage and drainage failure;

[0004] 2. Conventional fixation devices use a hard contact structure, which is prone to collapsing the lumen and affecting the drainage of cerebrospinal fluid and wound exudate;

[0005] 3. Patients need to maintain the standard postoperative position of the head of the bed at 30° and immobilize the head. Even slight movement can pull on the tubes, which may cause serious risks such as tube dislodgement and sudden changes in intracranial pressure.

[0006] 4. Twisted tubing often occurs under bedding, making it highly concealed and lacking an early warning mechanism, which can easily delay treatment and induce serious post-operative complications such as intracranial infection and hydrocephalus.

[0007] 5. Multiple tubing lines without classification labels are easily confused, increasing the probability of nursing errors;

[0008] 6. The use of some electrically or magnetically sensing alarm fixing devices is restricted in passive care, cleaning and sterilization, or magnetic resonance-related transportation scenarios.

[0009] Currently available pipeline fixing devices mostly focus on centralized clamping or simple storage, lacking a structure that combines independent zone limiting, adjustable angle guidance, purely mechanical torsion warning, and adjustable traction damping into the same pipeline management link. It is difficult to simultaneously meet the requirements of preventing multiple pipelines from crossing, non-collapse fixing, visual torsion warning, and safe traction of different drainage tubes. Summary of the Invention

[0010] In view of this, the present invention provides a multi-channel anti-torsion system after brain surgery, which independently limits multiple drainage tubes by means of pluggable partitioned retainers, changes the direction of drainage tubes by means of universal guide wheels corresponding to the outlets of each tube, and provides visual prompts when the tubes are twisted or pulled to a set degree by means of mechanical torsion prompt components and tube traction damping adjustment mechanisms, thereby reducing the risks of tube crossing, torsion, tube collapse and excessive traction.

[0011] To achieve the above objectives, one of the present invention provides the following technical solution:

[0012] A post-operative multi-channel anti-torsion system for brain surgery includes a multi-channel partitioned mounting bracket, a flexible anti-slip bushing, an adaptive guiding mechanism, a mechanical torsion warning component, and a tube traction damping adjustment mechanism. The multi-channel partitioned mounting bracket includes a housing, a cover plate, and pluggable mounting plates. Multiple vertical slots are spaced along the length of the housing cavity. Insertion of the mounting plates into these slots creates independent tube channels between adjacent plates. The cover plate has tube inlets and outlets corresponding to each tube channel. The flexible anti-slip bushing is positioned within the tube channels to provide non-collapsed limiting for the drainage tubes. An adaptive guiding mechanism is located at each tube outlet, comprising a horizontal connecting rod, a connecting ball, a support frame, a rotating shaft, and a guide wheel. The mechanical torsion warning component is linked to the rotating shaft and configured to extend a warning slider out of the housing when the rotating shaft reaches a preset warning angle. The tube traction damping adjustment mechanism is connected to the rotating shaft and adjusts the rotational resistance of the rotating shaft and guide wheel.

[0013] Furthermore, a fixing plate is provided at one end of the horizontal connecting rod near the box body. An elongated hole is provided on the fixing plate, and the fixing plate cooperates with the fastener on the box body through the elongated hole to adjust the horizontal position of the adaptive guide mechanism relative to the pipe outlet. The connecting ball is rotatably connected to the horizontal connecting rod, so that the support frame has a horizontal circumferential rotational degree of freedom and a vertical swinging degree of freedom relative to the pipe outlet.

[0014] Furthermore, the support frame is a U-shaped bracket, with the rotating shaft passing through the two side walls of the U-shaped bracket, and the guide wheel coaxially fixed in the middle of the rotating shaft; the guide groove is an arc-shaped groove adapted to the outer wall of the drainage tube to provide line contact or surface contact support when the drainage tube turns.

[0015] Furthermore, it also includes a locking mechanism, which includes a ratchet fixed to the end of the rotating shaft, a stop block disposed on the outside of the U-shaped bracket via a shaft pin, and a limiting pin; the stop block can switch between a locked state that engages with the ratchet teeth and a released state that disengages from the ratchet teeth. The locked state is used to limit the guide wheel angle when installing or tidying up the pipeline, and the released state is used to allow the rotating shaft to drive the mechanical torsion indicator component.

[0016] Furthermore, the mechanical twisting warning component includes a housing and a rotating cylinder, a traction wire, a rotating rod, a warning slider, a reset component, and an elastic component disposed within the housing; the rotating cylinder is driven by a rotating shaft, and a wire groove is provided on the outer wall of the rotating cylinder, the traction wire is wound in the wire groove and connected to one end of the rotating rod, and the other end of the rotating rod abuts against the warning slider; a sliding groove is provided on the side wall of the housing, and the warning slider is disposed in the sliding groove; when the rotating shaft drives the rotating cylinder to rotate and the winding length of the traction wire reaches the set length, the rotating rod pushes the warning slider to extend outward along the sliding groove.

[0017] Furthermore, the outer end of the warning slider is provided with a color mark or a raised mark, the reset component is a torsion spring or tension spring provided at the pivot of the rotating rod, and the elastic component is a compression spring or elastic sheet provided between the warning slider and the groove; the preset warning angle is determined by at least one of the initial winding length of the traction wire, the radius of the wire groove, and the lever arm of the rotating rod.

[0018] Furthermore, the pipeline traction damping adjustment mechanism includes a fixed seat, a friction ring, a rotating inner core, and an adjusting screw; the fixed seat is fixed to the outer wall of the support frame, the rotating inner core is coaxially fixed with the rotating shaft and rotates synchronously, the friction ring is clamped between the fixed seat and the rotating inner core, and the adjusting screw is exposed on the side wall of the fixed seat and is used to change the clamping force of the friction ring on the rotating inner core.

[0019] Furthermore, the flexible anti-slip bushing is a detachable cylindrical medical silicone part. The inner diameter of the flexible anti-slip bushing is clearance-fitted with the outer diameter of the drainage tube, and the outer diameter of the flexible anti-slip bushing matches the width of the pipeline channel. The outer surface of the flexible anti-slip bushing is provided with anti-slip protrusions that fit against the inner wall of the box or the card plate.

[0020] Furthermore, a lifting bracket is provided below the connecting ball. The lifting bracket is a telescopic rod structure and is used to adjust the height of the guide wheel relative to the box. An openable and closable fixing buckle is provided below the lifting bracket. The fixing buckle is used to fix and connect to the bed railing or bedside bracket. At least one of the multi-channel partition card seat, adaptive guide mechanism and flexible anti-slip bushing is a detachable and cleanable structure.

[0021] The second aspect of this invention provides the following technical solution:

[0022] A method of using the multi-channel anti-torsion system after brain surgery as described above includes the following steps:

[0023] S1. Based on the number and outer diameter of the drainage tubes to be managed, insert the card into the corresponding vertical slot of the box to form an independent pipeline channel corresponding to each drainage tube, and install the corresponding adaptive guide mechanism at the outlet of each pipeline.

[0024] S2. The flexible anti-slip bushing is placed on the outside of each drainage pipe, so that the flexible anti-slip bushing is located in the corresponding pipeline channel, and the drainage pipe enters from the corresponding pipeline inlet and exits from the corresponding pipeline outlet and fits the guide groove of the guide wheel.

[0025] S3. Fix the system to the bed railing or bedside bracket by fixing buckles, and adjust the position and angle of the guide wheel by adjusting the lifting bracket and connecting ball to ensure that the drainage tubes do not cross each other and maintain a loose margin.

[0026] S4. Tighten or loosen the adjusting screw according to the type of drainage tube or the preset safety traction requirements to match the rotational resistance of the pipeline traction damping adjustment mechanism with the current drainage tube.

[0027] S5. When the drainage tube is twisted or pulled and drives the guide wheel and rotating shaft to rotate to the preset prompt angle, the mechanical twist prompt component causes the warning slider to extend out of the housing to form a visual prompt.

[0028] S6. After the drainage tube is released from twisting or excessive pulling, the reset component and elastic component drive the rotating rod and the warning slider to reset, and the warning slider retracts into the groove.

[0029] The beneficial effects of this invention are as follows:

[0030] This invention uses a pluggable card plate and a vertical card slot to form multiple independent pipeline channels, and uses a flexible anti-slip bushing to limit the drainage tubes in a non-collapsed manner within the pipeline channels, so that drainage tubes of different numbers and outer diameters can be stored and led out separately, reducing the risk of multiple pipelines crossing and tangling and the pressure on the pipeline cavity.

[0031] This invention utilizes an adaptive guiding mechanism that corresponds to each pipeline outlet, allowing each drainage pipe to independently adjust its outlet direction via a connecting ball, lifting bracket, and guide wheel. Simultaneously, a mechanical twisting indicator component is linked to a rotating shaft. When the drainage pipe is twisted or pulled to a set degree, a warning slider extends to provide a visual indication, enabling on-site status alerts without the need for a power source.

[0032] This invention adjusts the rotational resistance of the guide wheel through a pipeline traction damping adjustment mechanism, so that the starting rotational force of the guide wheel matches the preset safety traction requirements of different types of drainage tubes, reducing false prompts caused by ordinary activities, and reducing the risk of abnormal pipeline position or detachment caused by continuous excessive traction.

[0033] Other advantages, objectives, and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination, or may be learned from practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

Detailed Implementation

[0046] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0047] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual pictures. They should not be construed as limiting the invention. To better illustrate the embodiments of the invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0048] like Figures 1 to 9 As shown, this embodiment provides a multi-channel anti-torsion system for post-brain surgery. The overall structure preferably uses medical-grade polymer materials as the main body, while metal transmission components can be made of titanium alloy or non-magnetic austenitic stainless steel. This system is a purely mechanical structure, requires no power supply, and is compatible with various sizes of drainage tubes 37 used in post-brain surgery, including those for the ventricles, lumbar cisterns, surgical cavities, and subdural areas. If used in MRI-related environments, its use should be confirmed according to the medical institution's material compatibility procedures.

[0049] The multi-channel partitioned card holder 1 includes a box body 2, which is a long, hollow structure. Multiple sets of vertical slots 3 are evenly spaced along the length of the inner cavity of the box body 2. Insertable card plates 4 are installed within the vertical slots 3, forming independent pipe channels 5 between adjacent card plates 4. The number and width of the pipe channels 5 can be adjusted by increasing or decreasing the number of card plates 4 and changing their insertion position to accommodate different numbers and outer diameters of drainage tubes 37. A cover plate 6 is hinged or snap-fitted to the top of the box body 2, forming a closed cavity when the cover plate 6 is closed with the box body 2. Pipe inlets 7 and outlets 8 are provided on the cover plate 6, corresponding one-to-one with each pipe channel 5, ensuring that each drainage tube 37 has an independent inlet and outlet path.

[0050] Eight adaptive guiding mechanisms 9 are installed at each of the eight pipeline outlets. Each adaptive guiding mechanism 9 includes a horizontal connecting rod 10. One end of the horizontal connecting rod 10 is detachably and fixedly connected to the side wall of the housing 2. A fixing plate 11 is installed at the end of the horizontal connecting rod 10. The fixing plate 11 has an elongated hole, which, through the cooperation of fasteners with the housing 2, allows for horizontal position adjustment, ensuring precise alignment between the adaptive guiding mechanism 9 and the pipeline channel 5. The distal end of the horizontal connecting rod 10 is rotatably connected to a connecting ball 12. The connecting ball 12 can rotate horizontally and adjust its vertical angle to adapt to the pipeline routing when the bed rails are raised, the head of the bed is raised, or the head is immobilized.

[0051] A vertical connecting rod 13 is fixedly connected to the upper end of the connecting ball 12, and the bottom end of the vertical connecting rod 13 is fixedly connected to the support frame 14. The support frame 14 is a U-shaped bracket, and a rotating shaft 15 is rotatably inserted between the two side walls of the U-shaped bracket. A guide wheel 16 is coaxially fixed at the middle position of the rotating shaft 15. An arc-shaped guide groove 17 is formed on the outer periphery of the guide wheel 16. The arc of the guide groove 17 is adapted to the outer wall of the drainage tube 37. The drainage tube 37 fits into the guide groove 17 to achieve guidance and support. The arc support surface of the guide groove 17 is used to reduce local hard bending and point extrusion.

[0052] In this embodiment, the guide wheel 16 is made of medical-grade elastic silicone, and the guide groove 17 has radial elastic deformation capability. At the same time, in conjunction with the angle adaptive adjustment function of the front universal connecting ball, it can adapt to different tube diameters by relying on the elastic deformation of the silicone groove for three commonly used clinical brain drainage tubes (outer diameter 2.0mm, 2.6mm, and 3.3mm), and adapt to different tube bending curvatures by combining the universal angle adjustment. It can be compatible with all specifications of brain drainage tubes without replacing the guide wheel.

[0053] One end of the rotating shaft 15 extends outward into a U-shaped bracket and is equipped with a locking mechanism 18. The locking mechanism 18 includes a ratchet 19 and a stop 20. The ratchet 19 is coaxially fixed to the end of the rotating shaft 15. The stop 20 is rotatably mounted on the outer wall of the U-shaped bracket via a pin. The front end of the stop 20 can engage with the tooth groove of the ratchet 19 to form a limit, and the rear end of the stop 20 is provided with a limit pin to limit the swing range of the stop 20. A torsion spring can be installed between the stop 20 and the U-shaped bracket to keep the stop 20 in the selected state under normal conditions. Before pipeline arrangement or transfer, the stop 20 can be engaged with the ratchet 19 to limit the angle of the guide wheel 16. When mechanical twisting prompts are required, the stop 20 can be moved to disengage it from the ratchet 19 or only retain the one-way retraction limit, so as not to block the rotation of the rotating shaft 15 in the prompting direction.

[0054] The other end of the rotating shaft 15 extends outward to a U-shaped bracket and is connected to a mechanical twisting warning component 21. The mechanical twisting warning component 21 includes a housing 22, within which a rotating cylinder 23, a rotating rod 24, and a warning slider 25 are installed. A wire groove is formed on the outer wall of the rotating cylinder 23, and a traction wire 26 is wound within the wire groove. One end of the traction wire 26 is fixed to the wire groove, and the other end is fixedly connected to the rotating rod 24. The rotating rod 24 is rotatably mounted within the housing 22 via a support shaft in its middle section. A torsion spring is provided at the point where the rotating rod 24 engages with the support shaft as a reset element. A sliding groove 27 is formed on the side wall of the housing 22, and the warning slider 25 is fitted within the sliding groove 27. A compression spring is provided between the warning slider 25 and the sliding groove 27 as an elastic element. A square hole 28 is formed on the upper surface of the rotating cylinder 23. A square block is integrally formed at the end of the rotating shaft 15, and the square block slides into the square hole 28, allowing the rotating shaft 15 to drive the rotating cylinder 23 to rotate synchronously. The preset prompt angle can be set by the initial winding length of the traction wire 26, the radius of the wire groove, and the lever arm of the rotating rod 24.

[0055] When the drainage tube 37 is twisted or subjected to tangential traction exceeding a preset traction threshold, the drainage tube 37 drives the guide wheel 16 and the rotating shaft 15 to rotate. The rotating shaft 15 drives the rotating cylinder 23 to rotate via a square block. The traction wire 26 is wound around and pulls the rotating rod 24 to swing. The rotating rod 24 pushes the warning slider 25 to overcome the force of the elastic element and slide outward along the slide groove 27 from the outer wall of the housing 22, forming a visual indication. After the twisted or pulled state is released, the reset element drives the rotating rod 24 to reset, and the elastic element pushes the warning slider 25 back into the slide groove 27, realizing automatic reset.

[0056] A lifting bracket 29 is installed below the connecting ball 12. The lifting bracket 29 is a telescopic rod structure with adjustable height. A fixing buckle 30 is installed at the bottom of the lifting bracket 29. The fixing buckle 30 is an openable and closable clamp used to fix the whole device to the bed railing, bedside bracket or designated installation position. The lifting bracket 29 and the connecting ball 12 are used together to adjust the height and angle of the guide wheel 16 relative to the pipeline outlet 8, so that the drainage tube 37 retains a slack at the outlet.

[0057] Each tubing channel 5 is equipped with a flexible anti-slip bushing 31. The flexible anti-slip bushing 31 is a cylindrical medical silicone component with an inner diameter that fits the outer diameter of the drainage tube 37 with a clearance, and an outer diameter that matches the width of the tubing channel 5. The outer surface of the flexible anti-slip bushing 31 has anti-slip protrusions that fit against the inner wall of the box 2 and the retaining plate 4 to prevent the flexible anti-slip bushing 31 and the drainage tube 37 from moving within the tubing channel 5. The material hardness of the flexible anti-slip bushing 31 can be selected as Shore A30-A70 to provide friction positioning while reducing the risk of crushing the wall of the drainage tube 37.

[0058] A pipe traction damping adjustment mechanism 32 is installed on the U-shaped support. The pipe traction damping adjustment mechanism 32 includes a fixed base 33, a friction ring 34, a rotating inner core 35, and an adjusting screw 36. The rotating inner core 35 is coaxially fixed and rotates synchronously with the rotating shaft 15. The fixed base 33 is fixedly connected to the outer wall of the U-shaped support, and the friction ring 34 is clamped between the fixed base 33 and the rotating inner core 35. The adjusting screw 36 is exposed on the side wall of the fixed base 33. By tightening or loosening the adjusting screw 36, the clamping force of the friction ring 34 can be changed, thereby adjusting the starting torque of the rotating shaft 15 and the guide wheel 16. If the radius of the guide wheel 16 is r and the preset traction threshold is F, the starting torque can be set according to M=r×F. The outer wall of the fixed base 33 can be provided with scale markings so that different types of drainage tubes 37 can correspond to different adjustment positions.

[0059] Example 2

[0060] A method for using the aforementioned multi-channel anti-torsion system after brain surgery specifically includes the following steps:

[0061] S1. Open the cover 6 of the multi-channel partition card holder 1. According to the number of tubes required clinically and the outer diameter of the tubes, insert the corresponding number of card plates 4 into the vertical slots 3 inside the box body 2 to form the corresponding number of independent tube channels 5. At the same time, install the same number of adaptive guide mechanisms 9 on the side wall of the box body 2.

[0062] S2. The flexible anti-slip bushing 31 is fitted onto the outside of each drainage tube 37, so that the flexible anti-slip bushing 31 is located inside the corresponding pipeline channel 5 and is in contact with the bottom wall of the box 2 and the clamping plate 4. The outlet end of the drainage tube 37 is passed through the pipeline outlet 8 of the cover plate 6 and the guide groove 17 of the guide wheel 16 in sequence.

[0063] S3. Close the cover plate 6 and fasten it in place. Fix the entire system to the bed railing or the designated installation position using the fixing buckle 30 at the bottom of the lifting bracket 29. Adjust the height of the lifting bracket 29 and the angle of the connecting ball 12 to make the drainage tubes 37 run smoothly and retain some slack.

[0064] S4. According to the type of the current drainage tube 37 or the preset safety traction requirements, adjust the damping value of the pipeline traction damping adjustment mechanism 32 by adjusting the adjusting screw 36 so that the starting torque of the guide wheel 16 matches the current drainage tube 37; then switch the locking mechanism 18 to a state that does not block the rotation of the rotating shaft 15 in the indicated direction.

[0065] S5. When the drainage tube 37 is twisted or overstretched, the tube drives the guide wheel 16 and the rotating shaft 15 to rotate, thereby driving the warning slider 25 of the mechanical twisting indicator component 21 to slide out of the housing 22, thus providing a visual warning to the user.

[0066] S6. After the drainage tube 37 is freed from twisting or excessive stretching, the mechanical twisting indicator component 21 automatically resets under the action of the reset component and the elastic component, the warning slider 25 retracts into the housing 22, and the system can continue to be used normally.

[0067] S7. After use, disassemble the detachable parts such as the card plate 4, flexible anti-slip bushing 31, guide wheel 16, and mechanical twisting indicator component 21, and clean, disinfect or sterilize them according to the medical institution's device processing procedures for reuse.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.

The lifting bracket is a telescopic rod structure and is used to adjust the height of the guide wheel relative to the box. An openable and closable fixing buckle is provided below the lifting bracket. The fixing buckle is used to fix and connect to the bed railing or bedside bracket. At least one of the multi-channel partition card seat, adaptive guide mechanism and flexible anti-slip bushing is a detachable and cleanable structure.

8. A method of using the postoperative multi-channel anti-torsion system for brain surgery according to any one of claims 1-7, characterized in that, Includes the following steps: S1. Based on the number and outer diameter of the drainage tubes to be managed, insert the card into the corresponding vertical slot of the box to form an independent pipeline channel corresponding to each drainage tube, and install the corresponding adaptive guide mechanism at the outlet of each pipeline. S2. The flexible anti-slip bushing is placed on the outside of each drainage pipe, so that the flexible anti-slip bushing is located in the corresponding pipeline channel, and the drainage pipe enters from the corresponding pipeline inlet and exits from the corresponding pipeline outlet and fits the guide groove of the guide wheel. S3. Fix the system to the bed railing or bedside bracket by fixing buckles, and adjust the position and angle of the guide wheel by adjusting the lifting bracket and connecting ball to ensure that the drainage tubes do not cross each other and maintain a loose margin. S4. Tighten or loosen the adjusting screw according to the type of drainage tube or the preset safety traction requirements to match the rotational resistance of the pipeline traction damping adjustment mechanism with the current drainage tube. S5. When the drainage tube is twisted or pulled and drives the guide wheel and rotating shaft to rotate to the preset prompt angle, the mechanical twist prompt component causes the warning slider to extend out of the housing to form a visual prompt. S6. After the drainage tube is released from twisting or excessive pulling, the reset component and elastic component drive the rotating rod and the warning slider to reset, and the warning slider retracts into the groove.
