Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, and in particular to a tubing restraint and positioning device for critical care instruments. Background Technology
[0002] In intensive care unit (ICU) clinical nursing, patients typically require connection to multiple life support devices such as ventilators, infusion pumps, and blood purification equipment, resulting in a large number and complexity of bedside tubing. Existing tubing fixation methods often rely on tape or simple hooks, lacking a systematic constraint and guidance mechanism. When the patient's position changes or nursing staff operate the equipment, the tubing is prone to tangling, twisting, kinking, or becoming blocked by pressure. In severe cases, this can even lead to accidental dislodgement, directly affecting the continuity of treatment and increasing medical risks. Furthermore, existing fixation devices are usually simple in structure and large in size, making it difficult to flexibly adjust their position in the already confined space of the ICU, and inconvenient to store and organize when not in use, reducing the efficiency of ward space utilization and the convenience of nursing procedures. Summary of the Invention
[0003] The present invention aims to at least partially solve one of the technical problems in the related art.
[0004] Therefore, the purpose of this invention is to propose a critical care instrument tubing constraint and positioning device. In view of the problems of existing critical care tubing being easily tangled and falling off, and the device occupying a large space and being inconvenient to store, the invention achieves orderly constraint, flexible positioning and compact storage of multiple tubing by setting up multiple positioning units.
[0005] To achieve the above objectives, the present invention proposes a critical care instrument tubing restraint and positioning device, comprising a movable base, a positioning mechanism, and a support rod. The support rod is disposed on the top of the movable base, and the positioning mechanism is disposed on the support rod. The positioning mechanism includes a rotating ring, a support plate, and positioning units. The rotating ring is movably sleeved on the support rod, the support plate is disposed on the side of the rotating ring, and the positioning units are evenly distributed on the top of the support plate. Each positioning unit has a groove structure, into which the instrument tubing is inserted.
[0006] In addition, the critical care instrument tubing restraint and positioning device proposed according to the present invention may also have the following additional technical features:
[0007] Specifically, the positioning unit includes a positioning frame, a spring, a clamping plate, an inner limiting frame, a baffle, and a limiting member. The positioning frame is located on the top of the support plate and has a U-shaped structure. The springs are symmetrically arranged on both sides inside the positioning frame. The inner limiting member is located inside the positioning frame and inserted into the center of the spring. The clamping plate is located in the groove structure of the positioning frame and is fixedly connected to the spring. The bottom of the baffle is hinged to the top of the clamping plate. The baffle and the clamping plate are hinged together by a damping pivot. The limiting member is movably located on the upper side of the inner wall of the positioning frame and is located between the baffle and the inner wall of the positioning frame. An alarm device is embedded in the center of the positioning frame.
[0008] Specifically, the side of the limiting member near the baffle is set as an inclined surface.
[0009] Specifically, the trays are symmetrically arranged in two sets, with a gap between the two sets of trays, and excess pipes are folded and stored in the gap.
[0010] Specifically, the rotating ring includes an inner ring and an outer ring. The inner ring is movably sleeved on the support rod, and the outer ring is rotatably sleeved on the outer side of the inner ring. The outer side of the outer ring is fixedly connected to the support plate.
[0011] Specifically, the support rod is provided with vertically arranged fixing screw holes, and an extension plate is connected to the lower part of the inner ring. A fixing screw corresponding to the fixing screw hole is rotatably inserted through the extension plate.
[0012] Specifically, the support rod is provided with a vertically arranged groove, a slide rail is provided in the groove, a sleeve block is movably sleeved on the slide rail, and the sleeve block is fixedly connected to the inner ring.
[0013] Specifically, the end of the fixing screw is provided with a rod structure that penetrates vertically.
[0014] Specifically, a limiting plate is sleeved at the lower end of the support rod.
[0015] Specifically, the movable base includes a base plate, a support frame, and movable wheels. The base plate is disposed under the support rod, the support frame is disposed under the base plate, the support frame has a cross structure, and the movable wheels are disposed under the end of the support frame.
[0016] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:
[0017] By coordinating the movable base, support rod, and positioning mechanism, a movable and height-adjustable tubing management terminal is constructed. The rotating ring in the positioning mechanism is moved and sleeved on the support rod, allowing the tray to rise and fall axially to adapt to different bed heights and patient positions. At the same time, the rotational freedom of the rotating ring allows the tray to rotate horizontally around the support rod, thereby adjusting the tubing outlet angle without moving the base, avoiding stress concentration caused by excessive traction angle. The groove structure in the positioning unit provides physical space for the instrument tubing, enabling the orderly arrangement of the tubing and eliminating the geometric conditions for tubing entanglement from the source.
[0018] Furthermore, the positioning unit uses a spring-driven clamping plate in conjunction with a damping shaft-connected baffle to form an adaptive elastic clamping mechanism. The setting of the limiting component and its inclined surface provides mechanical locking feedback after the baffle is closed in place, preventing the baffle from accidentally popping open due to vibration or accidental contact, thus improving the reliability of the constraint.
[0019] Furthermore, a gap is reserved between the two sets of trays. This spatial structure is specifically designed to coil and store redundant pipes, integrating excess pipes that were originally scattered around the bed or on the floor into the gap, significantly reducing the occupation of external space and solving the storage problem caused by the small space in the intensive care unit.

[0029] Embodiments of the present invention are described in detail below, examples of which are illustrated 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 intended to explain the invention, and should not be construed as limiting the invention. Rather, embodiments of the invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.
[0030] The following description, in conjunction with the accompanying drawings, describes the critical care instrument tubing constraint and positioning device according to an embodiment of the present invention.
[0031] Example 1
[0032] like Figure 1-6 As shown, this embodiment provides a critical care instrument tubing restraint and positioning device, including a movable base 1, a positioning mechanism 2, and a support rod 3, wherein the support rod 3 is disposed on the top of the movable base 1.
[0033] The positioning mechanism 2 is mounted on the support rod 3. The positioning mechanism 2 includes a rotating ring 4, a support plate 5, and a positioning unit 6. The rotating ring 4 is movably sleeved on the support rod 3.
[0034] The tray 5 is located on the side of the rotating ring 4.
[0035] It should be noted that the support plate 5 is connected to the rotating ring 4. Therefore, when the rotating ring 4 rotates relative to the support rod 3, the support plate 5 also makes circumferential adjustments. The horizontal outlet angle of the tubing can be changed by rotating the support plate 5 to make it conform to the actual connection direction between the instrument and the patient, thereby reducing the internal stress caused by the torsion of the tubing from the source.
[0036] Positioning units 6 are evenly arranged on the top of the support plate 5. The positioning unit 6 has a groove structure 18, and the instrument tubing is inserted into the groove structure 18.
[0037] It should be noted that the multiple positioning units 6 arranged evenly form an orderly constraint array on the tray 5. Each positioning unit 6 corresponds to one or a group of pipes. The geometric possibility of pipes crossing or tangling is eliminated by physical separation. The groove 18 structure provides a limiting space for the pipes. The initial limiting and guidance of the pipes are achieved by matching the geometric shapes.
[0038] Example 2
[0039] Based on the system-level framework constructed in Example 1, the positioning unit 6 includes a positioning frame 7, a spring 8, a clamping plate 9, an inner limiting frame 10, a baffle 11, and a limiting member 12. The positioning frame 7 is located on the top of the support plate 5 and has a U-shaped structure.
[0040] The U-shaped structure forms the main skeleton of the positioning unit 6, and its upward-facing shape naturally adapts to the insertion and removal path of the pipeline.
[0041] Springs 8 are symmetrically arranged on both sides inside the positioning frame 7.
[0042] It should be noted that when instrument tubes of different diameters are placed into the groove 18 structure, the springs 8 on both sides can undergo different degrees of compression deformation according to the outer diameter of the tube, thereby generating elastic restoring forces of equal magnitude and opposite direction.
[0043] The inner limiter 12 is set inside the positioning frame 7 and inserted into the center of the spring 8.
[0044] The inner limiting component 12 serves a dual purpose: firstly, it acts as a guide spindle for the spring 8, preventing lateral buckling instability during repeated compression; secondly, it serves as a travel limit reference for the movement of the clamping plate 9, ensuring that the clamping plate 9 always moves along a predetermined straight trajectory and avoiding jamming due to off-center loading. The clamping plate 9 is disposed within the groove 18 structure of the positioning frame 7 and is fixedly connected to the spring 8. As the end actuator that directly contacts the pipeline, the surface of the clamping plate 9 can be further coated with medical-grade silicone or soft rubber to increase the coefficient of friction and reduce wear on the pipeline surface.
[0045] The bottom of the baffle 11 is hinged to the top of the clamping plate 9, and the baffle 11 and the clamping plate 9 are hinged together by a damping pivot.
[0046] The viscous resistance characteristics of the damping shaft during the rotation of the baffle 11 prevent the baffle 11 from rapidly flipping under the action of gravity.
[0047] Specifically, when a nurse opens the baffle 11 with one hand to insert the tubing, the damping shaft can provide sufficient supporting torque to suspend the baffle 11 at any angle without the need for continuous support from the other hand; while when the baffle 11 is closed, the damping effect effectively buffers the instantaneous impact and prevents squeezing damage to the fragile tubing due to excessively fast movements.
[0048] The limiting member 12 is movably disposed on the upper side of the inner wall of the positioning frame 7, and is located between the baffle 11 and the inner wall of the positioning frame 7. The limiting member 12 constitutes a safety barrier to prevent the baffle 11 from being opened accidentally. After the baffle 11 is closed in place, the limiting member 12 restricts the reverse rotation freedom of the baffle 11 by physical blocking, thereby sealing the pipeline within the groove 18 structure. In order to further optimize the locking feel and reliability, the side of the limiting member 12 near the baffle 11 is set as an inclined surface, which essentially forms a one-way guiding wedge mechanism.
[0049] Specifically, when the baffle 11 closes upward, its edge first contacts the lower wide opening area of the inclined surface. As the baffle 11 continues to move, the edge of the baffle 11 slides along the inclined surface and gradually squeezes the limiting member 12 outward until the baffle 11 completely passes the bottom end of the limiting member 12. The limiting member 12 automatically returns to its original position under its own weight or auxiliary elastic force, which can effectively resist external interference such as equipment movement and personnel touch in the intensive care environment and ensure the absolute safety of pipeline restraint.
[0050] An alarm device 25 is embedded in the center of the positioning frame 7. The alarm device 25 is used to detect whether the pipeline has fallen out of the positioning frame 7. If it is detected that the pipeline has fallen out, an alarm will be sounded to remind the staff that the pipeline has come out.
[0051] Example 3
[0052] Based on the pipeline constraint and clamping mechanism constructed in Examples 1 and 2, this example further expands the functional layout of the tray 5 to address the practical problems of limited space and difficulty in managing redundant pipeline length in the intensive care unit.
[0053] Specifically, two sets of trays 5 are symmetrically arranged, with a gap between the two sets of trays 5. Excess pipes are folded and stored in the gap.
[0054] Specifically, the width, depth, and axial height of the gap are preset according to the bending radius and coiling volume of commonly used ventilator tubing and infusion tubing in clinical practice, so that it can accommodate at least one loop of tubing folding and coiling. This design forcibly integrates redundant tubing that was originally scattered on the bed rails, the ground, or the equipment belt into the gap, thereby significantly reducing the device's ineffective space encroachment on the external environment.
[0055] Example 4
[0056] Based on the pipeline constraint and storage system constructed in Examples 1 to 3, this example further specifies the connection adjustment mechanism between the positioning mechanism 2 and the support rod 3 to achieve multi-dimensional precision adjustment and attitude stability under high load.
[0057] Specifically, the rotating ring 4 includes an inner ring 13 and an outer ring 14. The inner ring 13 is movably sleeved on the support rod 3, and the outer ring 14 is rotatably sleeved on the outer side of the inner ring 13. The outer side of the outer ring 14 is fixedly connected to the support plate 5.
[0058] Specifically, the inner ring 13 is specifically responsible for the lifting and lowering motion along the axis of the support rod 3, while the outer ring 14 is specifically responsible for the circumferential rotational motion around the axis. Compared with the traditional structure where a single ring simultaneously undertakes sliding and rotational functions, this decoupled design avoids mutual interference between the lifting friction surface and the rotating friction surface, making the adjustments in the two directions independent of each other.
[0059] Specifically, the support rod 3 is provided with a vertically arranged groove 18, and a slide rail 19 is provided in the groove 18. A sleeve block 20 is movably sleeved on the slide rail 19, and the sleeve block 20 is fixedly connected to the inner ring 13.
[0060] Specifically, the slide rail 19 is embedded in the groove 18 of the support rod 3, which restricts the circumferential rotational freedom of the inner ring 13 relative to the support rod 3, ensuring that the lifting process is strictly carried out along a straight trajectory. At the same time, the cooperation between the sleeve block 20 and the slide rail 19 prevents the inner ring 13 from being directly subjected to lateral pressure and deformed or jammed.
[0061] Based on this, the support rod 3 has vertically arranged fixing screw holes 15, and the inner ring 13 is connected to the lower part of the extension plate 16. The extension plate 16 is rotatably connected with a fixing screw 17 corresponding to the fixing screw hole 15. The fixing screw 17 is used as an axial positioning element here. When it is necessary to lock the height, the fixing screw 17 is screwed in so that its end is pressed against the corresponding fixing screw hole 15; when it is necessary to adjust, the screw is unscrewed to release the axial constraint, and the inner ring 13 can slide freely under the guidance of the slide rail 19.
[0062] A rod structure is vertically inserted through the end of the fixing screw 17. This rod structure essentially constitutes a manually operated torque amplifying lever.
[0063] Specifically, when caregivers need to quickly tighten or loosen the fixing screw 17, they can generate sufficient rotational torque simply by turning the rod structure without the need for additional tools, overcoming the problem of insufficient friction when hands are slippery or gloves are worn.
[0064] Example 5
[0065] Based on the precision adjustment and pipeline constraint system constructed in Examples 1 to 4, this example further improves the engineering integrity and clinical safety of the device, focusing on the specific design of the ultimate protection of the support rod 3 and the mechanical stability of the movable base 1.
[0066] Specifically, a limiting plate 21 is sleeved at the lower end of the support rod 3. This limiting plate 21 constitutes the physical stop boundary for the axial movement of the positioning mechanism 2.
[0067] As the base platform that supports the entire device and enables flexible movement beside the bed, the mobile base 1 includes a base plate 22, a support frame 23, and moving wheels 24. The base plate 22 is located under the support rod 3; the support frame 23 is located under the base plate 22 and has a cross structure; the moving wheels 24 are located at the ends of the support frame 23.
[0068] In operation, the operator moves the rod structure on the extension plate 16, causing the fixing screw 17 to unscrew from the fixing screw hole 15 of the support rod 3, releasing the axial lock. At this time, the inner ring 13, guided by the slide rail 19 and the sleeve block 20, can smoothly slide along the axial direction of the support rod 3 to the target height. After reaching the predetermined position, the operator reverses the rod structure to re-screw the fixing screw 17 into the corresponding fixing screw hole 15, thus completing the precise height locking. When it is necessary to fix a newly connected pipeline, the operator lifts the baffle 11 upwards with one hand. The viscous resistance provided by the damping shaft allows the baffle 11 to be stably suspended at any opening angle, freeing up operating space to insert the pipeline without additional hand support. The pipeline is placed into the groove 1. After the structure is completed (8), the baffle 11 is released and slowly falls back under the action of gravity, avoiding the impact damage to the fragile tubing caused by instantaneous closure. When the baffle 11 falls, its edge contacts the top of the tubing, and at the same time, the springs 8 symmetrically arranged on both sides drive the clamping plate 9 to automatically fit against the outer wall of the tubing. It can provide uniform radial clamping force regardless of the diameter of the tubing to prevent slippage. When the straight distance between the instrument and the patient is less than the total length of the tubing, the operator can fold or coil the excess length of the tubing into the gap between the trays 5. The natural limiting of the side wall of the tray 5 prevents the tubing from falling outward. No additional straps or hooks are needed, which significantly reduces the encroachment on the limited operating space next to the bed and leaves a more spacious emergency passage for medical staff.
[0069] It should be noted that all components of the positioning mechanism 2 in this application are replaceable, disposable parts.
