Abstract
Description
Technical Field
[0001] This invention relates to the field of medical auxiliary device technology, and in particular to a tubing restraint and positioning device for surgical critical care instruments. Background Technology
[0002] Surgical critical care equipment refers to the general term for various medical devices used in surgical intensive care units to monitor, treat, and maintain the vital signs of critically ill patients. Surgical critical care equipment is connected to the patient's body through various tubes. These tubes are the patient's lifeline; if a problem occurs, the patient may die within minutes. It is necessary to restrain and position the tubes to ensure their safety during use.
[0003] Traditional restraint and positioning devices usually require the cooperation of both hands. First, the two support plates must be manually separated or opened, then the tubing must be aligned and inserted into the fixing hole or slot, and finally the lock must be tightened or fastened separately. When the tubing needs to be replaced or removed, it is often necessary to manually release the lock, loosen the lock, and pull the tubing out of the fixing slot. The operation is cumbersome and slow. Therefore, a restraint and positioning device for tubing in surgical critical care instruments is proposed. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as cumbersome and slow operation of positioning and unpositioning pipelines, and to propose a pipeline constraint and positioning device for surgical critical care instruments.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A surgical critical care instrument tubing restraint and positioning device includes a fixed base. Multiple first support plates are rotatably connected to the upper part of the fixed base. A second support plate is rotatably connected to the upper part of each first support plate. The second support plate is equipped with a restraint assembly. The restraint assembly includes a cylinder mounted on the upper part of the second support plate, an airbag jointly mounted on the inner sides of the first and second support plates, a piston slidably disposed on the inner side of the cylinder, an arc-shaped rod slidably disposed on the outer side of the second support plate, a limiting shell mounted on the outer side of the first support plate, a transmission unit jointly disposed between the piston and the arc-shaped rod, and a square rod mounted on the outer side of the piston. The second pressure block installed on the side of the rod and the pressure plate slidably arranged on the upper part of the cylinder are connected to the first support plate symmetrically and rotatably. The first arc plate rotates with the second support plate. The second arc plate rotates with the first arc plate. The pipeline can be quickly constrained and positioned by the expansion of the airbag and the locking of the first and second support plates. When it is necessary to remove it, the airbag can automatically contract by releasing the locking of the piston. At the same time, the first and second support plates will automatically unlock and the pipeline will be automatically lifted by the second arc plate, which facilitates the positioning and removal of the pipeline.
[0006] The above technical solution further includes: The upper part of the fixed base is rotatably connected to a first rotating rod, the first support plate is installed on the upper end of the first rotating rod, and a first torsion spring is installed on the bottom of the first support plate. The end of the first torsion spring away from the first support plate is fixedly connected to the first rotating rod.
[0007] A second rotating rod is rotatably connected to the inner side of the first support plate. A third rotating rod is installed at both ends of the second rotating rod. A second torsion spring is installed on the outer side of the third rotating rod. The other end of the second torsion spring is fixedly connected to the first support plate. When the second torsion spring is in a contracted state, it drives the second support plate to rotate through the second rotating rod and the third rotating rod, thus exposing the opening of the first support plate.
[0008] The first arc-shaped plate is rotatably connected to the end of the third rotating rod, and the two first arc-shaped plates and the second arc-shaped plate are respectively located on both sides of the first support plate.
[0009] A first telescopic rod is installed at the bottom of the piston, and the end of the first telescopic rod away from the piston is fixedly connected to the inner wall of the cylinder.
[0010] The transmission unit includes a first pressure block installed on the outer side of the arc-shaped rod, a second telescopic rod installed at the bottom of the piston, and a third telescopic rod installed at the end of the arc-shaped rod. The end of the third telescopic rod away from the arc-shaped rod is fixedly connected to the inner wall of the cylinder. When the arc-shaped rod moves, it is inserted into the limiting shell to automatically lock the first support plate and the second support plate.
[0011] The first pressure block has a trapezoidal cross-section and is positioned on the trajectory of the second telescopic rod.
[0012] A movable rod is mounted on the upper part of the piston, and the movable rod is slidably connected to the cylinder. The square rod is also slidably connected to the cylinder. A sliding groove is provided on the upper part of the cylinder. A sliding block is slidably arranged on the inner side of the sliding groove. The sliding block is fixedly connected to the pressure plate. A round rod is mounted on the side of the sliding block, and the round rod is slidably connected to the cylinder. A spring is mounted on the side of the sliding block near the round rod. The end of the spring away from the sliding block is fixedly connected to the inner wall of the sliding groove. A square plate is mounted on the end of the round rod away from the sliding block. The pressure plate is inserted between two second pressure blocks to lock the square rod and the piston.
[0013] The cross-sections of the multiple second pressure blocks are trapezoidal, and the pressure plate is located on the movement trajectory of the multiple second pressure blocks.
[0014] The size of the opening of the limiting shell is adapted to the size of the arc-shaped rod.
[0015] The present invention has the following beneficial effects: In this invention, by setting a constraint component, the pipeline can be quickly constrained and positioned by the expansion of the airbag and the locking of the first and second support plates. When it is necessary to remove the pipeline, the airbag can be automatically contracted by releasing the locking of the piston. At the same time, the first and second support plates are automatically unlocked, and the pipeline is automatically lifted by the second arc plate, thereby facilitating the positioning and removal of the pipeline.

[0018] 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.
[0019] like Figure 1 - Figure 9 As shown, the present invention proposes a surgical critical care instrument tubing restraint and positioning device, including a fixed base 1. Multiple first support plates 4 are rotatably connected to the upper part of the fixed base 1. Second support plates 5 are rotatably connected to the upper part of the first support plates 4. The second support plates 5 are provided with a restraint assembly, which includes a cylinder 12 mounted on the upper part of the second support plate 5, an airbag 11 jointly mounted on the inner sides of the first and second support plates 4 and 5, a piston 13 slidably mounted on the inner side of the cylinder 12, an arc-shaped rod 17 slidably mounted on the outer side of the second support plate 5, a limiting shell 19 mounted on the outer side of the first support plate 4, a transmission unit jointly provided between the piston 13 and the arc-shaped rod 17, and a square... The system includes a rod 21, a second pressure block 22 mounted on the side of the square rod 21, a pressure plate 25 slidably mounted on the upper part of the cylinder 12, a first arc plate 9 symmetrically rotatably connected to the outer side of the first support plate 4 and rotating with the second support plate 5, and a second arc plate 10 rotatably connected to the outer side of the first arc plate 9. The system can quickly constrain and position the pipeline by inflating the airbag 11 and locking the first support plate 4 and the second support plate 5. When it is necessary to remove the pipeline, the airbag 11 can automatically contract by releasing the lock on the piston 13. At the same time, the first support plate 4 and the second support plate 5 can automatically unlock, and the pipeline can be automatically lifted by the second arc plate 10, which facilitates the positioning and removal of the pipeline.
[0020] The upper part of the fixed base 1 is rotatably connected to the first rotating rod 2, the first support plate 4 is installed on the upper end of the first rotating rod 2, the bottom of the first support plate 4 is installed with the first torsion spring 3, and the end of the first torsion spring 3 away from the first support plate 4 is fixedly connected to the first rotating rod 2.
[0021] The inner side of the first support plate 4 is rotatably connected to the second rotating rod 6. The two ends of the second rotating rod 6 are each equipped with a third rotating rod 7. The outer side of the third rotating rod 7 is equipped with a second torsion spring 8. The other end of the second torsion spring 8 is fixedly connected to the first support plate 4. When the second torsion spring 8 is in a retracted state, it drives the second support plate 5 to rotate through the second rotating rod 6 and the third rotating rod 7, thus exposing the opening of the first support plate 4.
[0022] The first arc-shaped plate 9 is rotatably connected to the end of the third rotating rod 7, and the two first arc-shaped plates 9 and the second arc-shaped plate 10 are respectively located on both sides of the first support plate 4.
[0023] A first telescopic rod 14 is installed at the bottom of the piston 13, and the end of the first telescopic rod 14 away from the piston 13 is fixedly connected to the inner wall of the cylinder 12.
[0024] The transmission unit includes a first pressure block 18 installed on the outer side of the arc-shaped rod 17, a second telescopic rod 15 installed at the bottom of the piston 13, and a third telescopic rod 16 installed at the end of the arc-shaped rod 17. The end of the third telescopic rod 16 away from the arc-shaped rod 17 is fixedly connected to the inner wall of the cylinder 12. When the arc-shaped rod 17 moves, it is inserted into the limiting shell 19 to automatically lock the first support plate 4 and the second support plate 5.
[0025] The first pressure block 18 has a trapezoidal cross section and is positioned on the movement trajectory of the second telescopic rod 15.
[0026] A movable rod 20 is mounted on the upper part of the piston 13, and the movable rod 20 is slidably connected to the cylinder 12. A square rod 21 is slidably connected to the cylinder 12. A sliding groove 23 is opened on the upper part of the cylinder 12. A sliding block 24 is slidably arranged on the inner side of the sliding groove 23. The sliding block 24 is fixedly connected to the pressure plate 25. A round rod 27 is mounted on the side of the sliding block 24, and the round rod 27 is slidably connected to the cylinder 12. A spring 26 is mounted on the side of the sliding block 24 near the round rod 27. The end of the spring 26 away from the sliding block 24 is fixedly connected to the inner wall of the sliding groove 23. A square plate 28 is mounted on the end of the round rod 27 away from the sliding block 24. The pressure plate 25 is inserted between two second pressure blocks 22 to lock the square rod 21 and the piston 13.
[0027] The cross-section of the multiple second pressure blocks 22 is trapezoidal, and the pressure plate 25 is located on the movement trajectory of the multiple second pressure blocks 22.
[0028] The size of the opening of the limiting shell 19 is adapted to the size of the arc-shaped rod 17.
[0029] In this embodiment, when constraint positioning is required, the second support plate 5 can be rotated to expose the opening between the first support plate 4 and the second support plate 5. Simultaneously, the second rotating rod 6 and the third rotating rod 7 rotate, causing the second torsion spring 8 to contract. Then, the pipeline is placed between the first support plate 4 and the second support plate 5. Next, the movable rod 20 is pressed, causing the piston 13 to move downwards. When the piston 13 moves downwards, the first telescopic rod 14 contracts. Simultaneously, the movable rod 20 causes the square rod 21 to move downwards. When the square rod 21 moves downwards, it causes the second pressure block 22 to press against the pressure plate 25 through its inclined surface, thereby causing the pressure plate 25 to move along the sliding groove 23 via the sliding block 24. Simultaneously, it causes the spring 26 to contract. When the movable rod... When the square rod 21 is not moved downwards, the spring 26, which is in a contracted state, drives the pressure plate 25 to reset and insert between the two second pressure blocks 22, locking the square rod 21 and the piston 13. When the piston 13 moves downwards, it also drives the second telescopic rod 15 to press the inclined surface of the first pressure block 18, driving the arc rod 17 to move along the arc of the second support plate 5, and at the same time driving the third telescopic rod 16 to stretch. When the arc rod 17 moves, it inserts into the limiting shell 19, automatically locking the first support plate 4 and the second support plate 5. At the same time, when the piston 13 moves downwards, it drives the air inside the cylinder 12 to enter the airbag 11 and expand. The expansion of the airbag 11 adapts to the fixation of the pipeline. When the pipeline is stretched, it can... The first support plate 4 and the first rotating rod 2 rotate, simultaneously causing the first torsion spring 3 to retract. After the tension is released, the first support plate 4 and the pipeline can be reset by the reset of the first torsion spring 3. When it is necessary to remove the pipeline, the square plate 28 can be pulled. The square plate 28 drives the sliding block 24 to move along the sliding groove 23 through the round rod 27, and at the same time drives the pressure plate 25 to move, so that the pressure plate 25 is no longer between the two adjacent second pressure blocks 22, and no longer locks the square rod 21 and the piston 13. At this time, the first telescopic rod 14, which is in a retracted state, drives the piston 13 to reset, and at the same time draws the gas inside the airbag 11 into the cylinder 12, so that the airbag 11 retracts and no longer fixes the pipeline, and at the same time moves the piston 13 upward. When the second telescopic rod 15 is reset, it no longer presses against the first pressure block 18. At this time, the third telescopic rod 16, which is in a retracted state, is reset and moves the arc-shaped rod 17 to the outside of the limiting shell 19, releasing the connection between the first support plate 4 and the second support plate 5. At this time, the second torsion spring 8, which is in a retracted state, drives the second rotating rod 6 and the third rotating rod 7 to reset, causing the second support plate 5 to rotate and expose the opening of the first support plate 4. At the same time, when the third rotating rod 7 rotates, it drives the first arc-shaped plate 9 to rotate. When the first arc-shaped plate 9 rotates, it drives the second arc-shaped plate 10 to rotate. The second arc-shaped plate 10 lifts the pipeline to the outside of the first support plate 4, which facilitates quick positioning and release of the pipeline.
