Abstract
Description
Technical Field
[0001] This invention relates to the field of nursing technology, and in particular to a nursing wiring conduit constraint and positioning device. Background Technology
[0002] Medical equipment such as electrocardiogram monitors, ventilators, and infusion pumps all need to be connected to patients via wiring to monitor their vital signs or provide necessary treatment. Furthermore, infusion tubing and drainage tubes are crucial channels for delivering medications, nutritional solutions, or removing waste fluids. If these lines and tubing are not properly secured and positioned, problems such as impaired drug delivery, inadequate drainage, or tubing dislodgement may occur, affecting the accuracy and effectiveness of treatment. Securely positioned lines and tubing are neater and more organized, facilitating routine nursing procedures for healthcare professionals.
[0003] Conventional tubing restraint and positioning devices typically use medical tape to directly attach the tubing or wiring to the patient's skin or bed sheets. If the patient is a child or has a mental illness and lacks safety awareness, they may accidentally pull on the tubing or wiring. The pulling force on the tubing or wiring can be transmitted to the connection point between the tubing and the patient. If important tubing such as endotracheal tubes or breathing tubes are pulled, it can easily lead to displacement or dislodgement of the endotracheal tube, causing interruption of nursing care and endangering the patient's life. Therefore, a nursing tubing restraint and positioning device is proposed. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies where patients may accidentally pull on the wiring conduit, causing the pulling force on the conduit to be easily transmitted to the connection point between the conduit and the patient, leading to interruptions in nursing care and affecting the patient's life safety. Therefore, this invention proposes a wiring conduit restraint and positioning device for nursing care.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A nursing wiring conduit constraint and positioning device includes a base, with multiple cylinders mounted on the upper part of the base. A rotating plate is rotatably connected to the inner side of each cylinder. Two first constraint wheels are mounted on the upper part of the rotating plate. A support rod is mounted on the upper part of the rotating plate, and a second constraint wheel is mounted on the upper part of the support rod. A release assembly is shared on the cylinders, rotating plate, and second constraint wheels. The release assembly includes a torsion spring shared between the cylinders and rotating plate, a limiting plate movably connected to the inner side of the cylinders, multiple protrusions mounted on the outer side of the rotating plate, a semicircular plate movably connected to the upper part of the cylinders, a fixing strap mounted on the side of the semicircular plate, a connecting rope shared between the semicircular plate and the limiting plate, a limiting rod symmetrically slidably mounted on the inner side of the second constraint wheel, and a first constraint wheel slidably mounted on the outer side of the second constraint wheel. A transmission unit is jointly provided between a movable plate, a second movable plate movably connected to the upper part of the first movable plate, a rotating plate, and a second constraint wheel. Rotating the rotating plate causes the torsion spring to contract, and the limiting plate limits the rotating plate by inserting between two adjacent protrusions. The wiring conduit is wound around the two first constraint wheels or the second constraint wheel. When the wiring conduit is pulled, it drives the semicircular plate and the fixing belt to move. The semicircular plate pulls the limiting plate to move through the connecting rope to release the limitation on the rotating plate. The torsion spring drives the rotating plate and the first constraint wheel to rotate and release the wiring conduit. When the rotating plate rotates, it drives the first and second movable plates to move upward through the transmission unit and pushes the wiring conduit. The two limiting rods retract to the inside of the second constraint wheel. A rubber ring is installed on the outside of the rotating plate, and a compression plate is movably connected to the inside of the cylinder.
[0006] The above technical solution further includes: A guide rod is installed on the inner side of the cylinder, and the guide rod is movably connected to the extrusion plate. A threaded rod is threadedly connected to the inner side of the cylinder, and the end of the threaded rod is rotatably connected to the extrusion plate. The force generated by the rotation of the threaded rod drives the extrusion plate to move along the guide rod.
[0007] A first telescopic rod is installed on the upper part of the cylinder. The end of the first telescopic rod away from the cylinder is fixedly connected to a semi-circular plate. The semi-circular plate and the fixing strap are fixedly connected by Velcro. The extension of the first telescopic rod buffers the pipeline.
[0008] A square groove is provided on the inner side of the cylinder, and a square plate is installed on the inner side of the square groove. Second telescopic rods are symmetrically installed on the side of the square plate. The ends of the two second telescopic rods away from the square plate are fixedly connected to the limiting plate. The connecting rope is movably connected to both the cylinder and the square plate. When the semicircular plate moves up, the limiting plate can be pulled to the inner side of the square groove by the connecting rope, thereby releasing the limitation on the rotating plate.
[0009] The transmission unit includes an L-shaped rod mounted on the side of the first movable plate, a trapezoidal plate mounted on the upper part of the cylinder, a hollow box mounted on the upper part of the trapezoidal plate, and an impact rod mounted on the side of the L-shaped rod. After the L-shaped rod rotates one revolution, it presses the inclined surface of the trapezoidal plate and causes the impact rod to press the hollow box. The impact rod hitting the hollow box can make a sound, prompting medical staff to check in time.
[0010] The upper part of the first movable plate is symmetrically equipped with third telescopic rods, and the ends of the two third telescopic rods away from the first movable plate are fixedly connected to the second movable plate.
[0011] The transmission unit also includes a sliding groove on the inner side of the second constraint wheel, a sliding plate slidably disposed on the inner side of the sliding groove, a push rod installed on the upper part of the first movable plate, and pressure blocks installed on the sides of the two limit rods. A fifth telescopic rod is installed between the two pressure blocks. The cross-section of the pressure block is trapezoidal, and the inclined surface of the pressure block is above the movement trajectory of the push rod. After the push rod moves upward, it squeezes the inclined surfaces of the two limit rods respectively, and drives the two limit rods to move simultaneously to the inner side of the second constraint wheel.
[0012] A fourth telescopic rod is installed on the upper part of the sliding plate, and the end of the fourth telescopic rod away from the sliding plate is fixedly connected to the inner wall of the sliding groove.
[0013] The upper part of the second constraint wheel is symmetrically provided with through slots, and the size of the through slot opening is adapted to the size of the push rod.
[0014] The base is symmetrically equipped with fixing straps at its bottom, which fix the base to the side of the bed. The bottom of the rotating plate is equipped with a rotating rod, which is rotatably connected to the cylinder.
[0015] The present invention has the following beneficial effects: 0. In this invention, by setting a release component, when the line or pipeline is pulled after being constrained and positioned, it can quickly respond and release the line, achieving rapid release. The release of the line or pipeline can offset part of the pulling force, avoiding the line or pipeline from being broken after being pulled, thus interrupting the nursing work. Furthermore, different constraint methods can be selected according to the length and fragility of the line or pipeline.
[0016] 1. In this invention, for pipelines with relatively fragile materials, friction can be generated by changing the degree of compression of the rubber ring by the extrusion plate, thereby slowing down the rotation speed of the rotating plate and reducing the release speed of the line or pipeline, thus avoiding damage caused by excessive release.

Detailed Implementation
[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] Example 1 like Figure 1 - Figure 10As shown, the present invention proposes a nursing wiring conduit constraint and positioning device, comprising a base 1, a plurality of cylinders 3 mounted on the upper part of the base 1, a rotating plate 4 rotatably connected to the inner side of the cylinders 3, two first constraint wheels 5 mounted on the upper part of the rotating plate 4, a support rod 21 mounted on the upper part of the rotating plate 4, and a second constraint wheel 22 mounted on the upper part of the support rod 21. A release assembly is provided on the cylinders 3, the rotating plate 4, and the second constraint wheel 22. The release assembly includes a torsion spring 10 mounted between the cylinders 3 and the rotating plate 4, a limiting plate 18 movably connected to the inner side of the cylinders 3, a plurality of protrusions 15 mounted on the outer side of the rotating plate 4, a semicircular plate 7 movably connected to the upper part of the cylinders 3, a fixing strap 8 mounted on the side of the semicircular plate 7, a connecting rope 20 mounted between the semicircular plate 7 and the limiting plate 18, a limiting rod 34 symmetrically slidably arranged on the inner side of the second constraint wheel 22, and a first movable... A transmission unit is jointly provided between plate 27, second movable plate 29 movably connected to the upper part of the first movable plate 27, rotating plate 4 and second constraint wheel 22. Rotating the rotating plate 4 causes the torsion spring 10 to contract, and the limiting plate 18 limits the rotating plate 4 by inserting between two adjacent protrusions 15. The line pipe is wrapped around the two first constraint wheels 5 or the second constraint wheel 22. After the line pipe is pulled, it drives the semicircular plate 7 and the fixing belt 8 to move. The semicircular plate 7 pulls the limiting plate 18 to move through the connecting rope 20 to release the limitation on the rotating plate 4. The torsion spring 10 drives the rotating plate 4 and the first constraint wheel 5 to rotate and release the line pipe. When the rotating plate 4 rotates, it drives the first movable plate 27 and the second movable plate 29 to move upward through the transmission unit and push the line pipe. The two limiting rods 34 contract to the inside of the second constraint wheel 22. A rubber ring 11 is installed on the outside of the rotating plate 4, and a compression plate 12 is movably connected to the inside of the cylinder 3.
[0021] A first telescopic rod 6 is installed on the upper part of the cylinder 3. The end of the first telescopic rod 6 away from the cylinder 3 is fixedly connected to the semicircular plate 7. The semicircular plate 7 and the fixing strap 8 are fixedly connected by Velcro. The extension of the first telescopic rod 6 buffers the pipeline.
[0022] A square groove 16 is provided on the inner side of the cylinder 3. A square plate 17 is installed on the inner side of the square groove 16. Second telescopic rods 19 are symmetrically installed on the side of the square plate 17. The ends of the two second telescopic rods 19 away from the square plate 17 are fixedly connected to the limiting plate 18. The connecting rope 20 is movably connected to both the cylinder 3 and the square plate 17. When the semicircular plate 7 moves upward, the limiting plate 18 can be pulled to the inner side of the square groove 16 by the connecting rope 20, thereby releasing the limitation on the rotating plate 4.
[0023] The transmission unit includes an L-shaped rod 23 mounted on the side of the first movable plate 27, and a trapezoidal plate 24 mounted on the upper part of the cylinder 3.
[0024] The upper part of the first movable plate 27 is symmetrically equipped with third telescopic rods 28, and the ends of the two third telescopic rods 28 away from the first movable plate 27 are fixedly connected to the second movable plate 29.
[0025] The transmission unit also includes a sliding groove 30 on the inner side of the second constraint wheel 22, a sliding plate 31 slidably disposed on the inner side of the sliding groove 30, a push rod 33 installed on the upper part of the first movable plate 27, a pressure block 35 installed on the side of each of the two limit rods 34, and a fifth telescopic rod 36 installed between the two pressure blocks 35. The cross section of the pressure block 35 is trapezoidal, and the inclined surface of the pressure block 35 is above the movement trajectory of the push rod 33. After the push rod 33 moves upward, it squeezes the inclined surfaces of the two limit rods 34 respectively, and drives the two limit rods 34 to move simultaneously to the inner side of the second constraint wheel 22.
[0026] A fourth telescopic rod 32 is installed on the upper part of the sliding plate 31, and the end of the fourth telescopic rod 32 away from the sliding plate 31 is fixedly connected to the inner wall of the sliding groove 30.
[0027] The upper part of the second constraint wheel 22 is symmetrically provided with through grooves 37, and the size of the opening of the through grooves 37 is adapted to the size of the push rod 33.
[0028] The bottom of the base 1 is symmetrically equipped with fixing straps 2, which fix the base 1 to the side of the bed. The bottom of the rotating plate 4 is equipped with a rotating rod 9, which is rotatably connected to the cylinder 3.
[0029] In this embodiment, when it is necessary to constrain and position the pipeline, the nursing device 1 can be fixed to the bedside using the fixing strap 2. Then, the rotating plate 4 is rotated one revolution, causing the rotating plate 4 to rotate via the rotating rod 9. At this time, the torsion spring 10 retracts. When the rotating plate 4 rotates, it presses the inclined surface of the limiting plate 18 through multiple protrusions 15. At this time, the second telescopic rod 19 retracts. When the limiting plate 18 is inserted between two adjacent protrusions 15, the second telescopic rod 19, which is in the retracted state, drives the limiting plate 18 to reset. The rotating plate 4 is limited by the insertion of the limiting plate 18 between two adjacent protrusions 15. If the pipeline is long, it can be wrapped. The wire is wound multiple times around the second constraint wheel 22, and the second movable plate 29 can be moved upward by the telescopic property of the third telescopic rod 28, fixing the wound wire between the third telescopic rod 28 and the limiting rod 34. If the wire is short and fragile, it can be wrapped crosswise around the two first constraint wheels 5 to reduce the compression between the wires. The wire can be placed between the semicircular plate 7 and the fixing strap 8, and then fixed with Velcro. When the wire is pulled, it will move the semicircular plate 7 and the fixing strap 8, causing the semicircular plate 7 to move upward and pulling the first telescopic rod 6. The extension buffers the conduit. Simultaneously, as the semicircular plate 7 moves upward, the connecting rope 20 pulls the limiting plate 18, causing it to move to the inside of the square groove 16. At this time, the second telescopic rod 19 retracts, and the limiting plate 18 no longer limits the protrusion 15. The torsion spring 10, now in a retracted state, drives the rotating plate 4 to rotate and reset. The rotation of the rotating plate 4 drives the two first constraint wheels 5 to rotate, thus quickly releasing the conduit. Furthermore, the rotation of the rotating plate 4 drives the L-shaped rod 23 to rotate. After rotating one revolution, the L-shaped rod 23 presses against the inclined surface of the trapezoidal plate 24, simultaneously causing the first movable plate 27 to move upward. After the first movable plate 27 moves upward, it passes through… The sliding plate 31 drives the push rod 33 to move upward. At this time, the fourth telescopic rod 32 retracts. After the push rod 33 moves upward, it squeezes the inclined surfaces of the two limiting rods 34 respectively until it passes through the through groove 37 to the outside of the second constraint wheel 22. It also drives the two limiting rods 34 to move to the inside of the second constraint wheel 22 at the same time. At this time, the first movable plate 27 and the second movable plate 29 continue to move upward and push the pipeline to the outside of the second constraint wheel 22, thereby releasing the pipeline. This allows the pipeline to be released quickly after being pulled, which can offset most of the pulling force and prevent the pipeline from breaking after being pulled, thus avoiding interruption of the nursing work.
[0030] Example 2 like Figure 1 - Figure 10As shown, based on Embodiment 1, a guide rod 13 is installed on the inner side of the cylinder 3. The guide rod 13 is movably connected to the extrusion plate 12. A threaded rod 14 is threadedly connected to the inner side of the cylinder 3. The end of the threaded rod 14 is rotatably connected to the extrusion plate 12. The force generated by the rotation of the threaded rod 14 drives the extrusion plate 12 to move along the guide rod 13.
[0031] A hollow box 25 is installed on the upper part of the trapezoidal plate 24, and an impact rod 26 is installed on the side of the L-shaped rod 23. After the L-shaped rod 23 rotates once, it presses the inclined surface of the trapezoidal plate 24 and causes the impact rod 26 to press the hollow box 25. The impact rod 26 can send out a sound when it hits the hollow box 25, prompting medical staff to check in time.
[0032] In this embodiment, if a relatively fragile pipe is wrapped around the first constraint wheel 5, the threaded rod 14 can be rotated. The force generated by the rotation of the threaded rod 14 drives the extrusion plate 12 to move along the guide rod 13, while simultaneously extruding the rubber ring 11. This causes friction to be generated when the rotating plate 4 rotates to release the pipeline, slowing down the rotation speed and thus reducing the release speed. This prevents damage to the pipeline due to excessive release speed. Furthermore, when the L-shaped rod 23 extrudes the trapezoidal plate 24, causing the first movable plate 27 and the second movable plate 29 to move upward and push the pipeline, the impact rod 26 can strike the hollow box 25 and emit a sound to alert medical personnel to check in time.
[0033] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
