Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a cannula fixer for critical care medicine. Background Art

[0002] In the intensive care unit (ICU), intubation is a crucial medical procedure. Tracheal intubation maintains ventilation, ensures airway patency, and prevents serious consequences such as suffocation and hypoxia caused by airway obstruction. It improves ventilation and provides effective artificial ventilation for patients with respiratory failure, asphyxiation, and other conditions, maintaining vital signs. It also prevents aspiration and reduces the risk of lung infection, facilitating drug therapy by allowing drugs to directly affect the respiratory tract and enhance therapeutic efficacy. Gastric intubation can provide gastrointestinal decompression, prevent aspiration, provide nutritional support, and administer medication. Ventricular drainage tube intubation drains fluid, reduces blood irritation to the meninges, lowers intracranial pressure, and facilitates infection control. Thoracic drainage tubes remove free air or blood that can cause breathing difficulties, promote lung expansion, and monitor drainage fluid levels. Abdominal drainage tubes drain pus, blood, and fluid accumulated within the abdominal cavity to the outside of the body, providing therapeutic or preventive treatment. It can be seen that intubation is crucial for maintaining patient life, improving ventilation status and conducting related treatments.

[0003] Currently, during the intubation treatment of patients, the angle at which the tube is inserted into the patient's body and the angle at which the tube is connected to the treatment instrument are difficult to maintain alignment and levelness, and thus the tube will inevitably bend and fold. When the tube is excessively bent and folded, the liquid or oxygen in the tube will be blocked, affecting the patient's treatment. Therefore, the present invention provides an intubation fixator for critical care medicine to meet the needs. Summary of the Invention

[0014] Optionally, a second hinge block is fixed to the side of the second support arm away from the first support arm, and a shaft rod is passed through the second hinge block, and both ends of the shaft rod pass through the side wall of the main frame. A shaft sleeve is fixed to the side wall of the main frame and is mounted on the end of the shaft rod. A torsion spring mounted on the shaft rod is assembled in the shaft sleeve.

[0015] Optionally, the mounting bracket includes a vertically arranged first outer tube and a horizontally arranged second outer tube, the bottom end of the first outer tube is equipped with a fixing clamp that can be clamped and fixed on one side of the bed, the top end of the first outer tube is vertically movably penetrated by a first inner rod, the top end of the side wall of the first outer tube is threadedly penetrated by a first positioning bolt for tightly positioning the first inner rod, the top end of the first inner rod is threadedly inserted with a fastening screw, the fastening screw is movably sleeved with a sleeve block, the second outer tube is horizontally fixed to the side wall of the sleeve block, the end of the second outer tube away from the sleeve block is movably penetrated by a second inner rod, the side wall of the second outer tube away from the sleeve block is threadedly penetrated by a second positioning bolt for tightly positioning the second inner rod, and the main frame is fixedly assembled on the end of the second inner rod extending out of the second outer tube.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, the present invention provides support for the medical pipeline by setting the first support arm and the second support arm, and the medical pipeline passes through the first support arm and the second support arm. The distance between the first support arm and the second support arm is adjusted and the first support arm and the second support arm are made to buckle the medical pipeline, and the medical pipeline can be adapted to different sizes of medical pipeline supports.

[0018] The present invention adopts the curved structural design of the top end of the second support arm and the curved structural design of the first support arm, and the hinged installation of the first support arm and the second support arm. When the medical pipeline is bent, the medical pipeline can form two arc-shaped bends between the bottom ends of the first support arm and the second support arm and at the top end of the second support arm, so that the medical pipeline can smoothly transition at the support point during the turning and arrangement process, preventing the medical pipeline from being damaged by bending and the phenomenon of liquid or oxygen in the pipeline being blocked.

[0019] The present invention adopts a special structural design in which the thickness of the arc-shaped curved portion of the first support arm gradually increases from bottom to top toward the side of the second support arm. In combination with a stop block and a stop pillow, when the turning angle of the medical pipeline continues to increase, the medical pipeline can be locked to limit further turning and bending, thereby achieving a locking stop at the maximum arrangement and turning angle of the medical pipeline, ensuring that the medical pipeline will not be damaged by bending due to excessively large bending and turning angles, and that the liquid or oxygen in the pipeline will not be blocked.

[0020] The present invention utilizes a fixing clamp to fix the first outer tube to one side of the patient's bed. At this time, the first outer tube, the first inner rod, the second outer tube and the second inner rod cooperate to support the main frame. The height of the main frame can be adjusted by extending and retracting the first inner rod and positioning the first inner rod by screwing the first positioning bolt. The extended length of the main frame can be adjusted by extending and retracting the second inner rod at the end of the second outer tube and tightening and positioning the second inner rod by screwing the second positioning bolt. The orientation of the main frame can be adjusted by loosening the fastening screw, rotating the sleeve block and the sleeve block, and tightening the fastening screw again to clamp and position the sleeve block, thereby improving the flexibility of the fixator.

[0038] like Figures 1 to 4 As shown, an embodiment of the present invention provides a cannula holder for critical care medicine, comprising a main frame 1; a second support arm 3 hingedly mounted in the main frame 1; a first support arm 2 hingedly mounted in the main frame 1 and capable of approaching the second support arm 3; the rotation directions of the first support arm 2 and the second support arm 3 are on the same plane, the first support arm 2 is curved in an arc shape, the arc concave surface of the first support arm 2 faces the side of the second support arm 3, and the top end of the second support arm 3 is smoothly curved toward the side away from the first support arm 2. Through this structural method, after the main frame 1 is assembled and fixed, the first support arm 2 is used to approach the second support arm 3 to clamp the medical pipeline, thereby achieving positioning support for the medical pipeline. When the medical pipeline needs to bend and turn, the curved structure design at the top end of the second support arm 3 can provide arc support for the medical pipeline, preventing the medical pipeline from being excessively bent and damaged at the support points of the first support arm 2 and the second support arm 3, and preventing liquid or oxygen in the pipeline from being blocked.

[0039] like Figures 1 to 4 As shown, an adjustment plate 8 is movably provided in the main frame 1, and the adjustment plate 8 slides and fits with the inner wall of the main frame 1. The adjustment plate 8 is located on the side of the first support arm 2 away from the second support arm 3 and is hingedly installed for the first support arm 2. An adjusting bolt 9 is threadedly passed through the side wall of the main frame 1 close to the adjustment plate 8. The adjusting bolt 9 is connected to the adjustment plate 8 in a rotatable hinged manner. By turning the adjusting bolt 9, the adjustment plate 8 is driven to move closer to or away from the second support arm 3, and the distance between the first support arm 2 and the second support arm 3 is adjusted to adapt to the size of the medical pipeline, and can be used to clamp the medical pipeline between the first support arm 2 and the second support arm 3.

[0040] like Figures 2 to 7 As shown, the first support arm 2 and the second support arm 3 have first and second adaption grooves 4 and 5 on their facing surfaces, respectively, to accommodate the insertion of medical tubing, allowing the first and second support arms 2 and 3 to interlock and support the medical tubing. An auxiliary pulley 20 is mounted at the bottom end of the second support arm 3. As the second support arm 3 rotates to coordinate with the medical tubing's diversion and arrangement, the auxiliary pulley 20 allows the bottom end of the second support arm 3 to roll against the tubing, reducing wear on the tubing.

[0041] like Figures 2 to 7 As shown, the hinge axes of the first support arm 2 and the second support arm 3 are at the same horizontal position, and the bending center of the first support arm 2 is at the same horizontal position as the hinge axis of the second support arm 3. A first hinge block 13 is provided at the middle position of the arc-shaped curved portion of the first support arm 2 facing the adjustment plate 8, and the first hinge block 13 is hinged to the adjustment plate 8. Through the above-mentioned structural manner, as the medical pipeline bends toward the side of the second support arm 3, the second support arm 3 rotates adaptively with the medical pipeline, and the bottom end of the second support arm 3 pushes the medical pipeline to move along the arc-shaped curved portion of the first support arm 2, thereby forming two arc-shaped bends between the bottom ends of the first support arm 2 and the second support arm 3 and at the top end of the second support arm 3, which are used to cooperate with the steering arrangement of the medical pipeline, so that the medical pipeline can smoothly transition at the support point during the steering arrangement process, reducing the bending wear of the medical pipeline.

[0042] like Figures 2 to 7As shown, the bottom end of the first support arm 2 extends vertically downward and is fixedly connected to a stop block 6. A stop pillow 7 opposite to the stop block 6 is provided on the side of the bottom of the main frame 1 near the second support arm 3. The stop pillow 7 includes a fixed plate 15 fixed to the bottom of the main frame 1. The bottom end of the fixed plate 15 is bent toward the stop block 6 and is connected to a stop pillow 16. A reinforcement plate 17 is connected between the vertical arm of the fixed plate 15 and the bottom of the main frame 1. The reinforcement plate 17 is a triangular structure and is used to reinforce the fixed plate 15. The stop pillow 16 is made of rubber. The bottom of the first hinge block 13 is set to a rectangular structure, and the top of the first hinge block 13 facing the adjustment plate 8 is set to a semicircular structure. The thickness of the arc-shaped curved portion of the first support arm 2 gradually increases from bottom to top toward the second support arm 3. The stop block 6 has an inclined surface facing away from the stop pillow 16. Through the above-mentioned structural manner, when the bottom end of the second support arm 3 pushes against the medical pipeline and is at the part of the first support arm 2 lower than the first hinge block 13, the rectangular surface of the bottom of the first hinge block 13 abuts against the adjustment plate 8, limiting the rotation of the bottom of the first support arm 2 away from the second support arm 3. When the bottom end of the second support arm 3 pushes against the medical pipeline and moves to a position above the first hinge block 13 of the first support arm 2, in conjunction with the arc structure at the top of the first hinge block 13, the thickness of the arc curved portion of the first support arm 2 gradually increases from bottom to top toward the second support arm 3. The top of the first support arm 2 will be forced to rotate toward the side away from the second support arm 3, and the stop block 6 at the bottom end of the first support arm 2 will move close to the stop pillow 7. The stop block 6 will then push the medical pipeline against the stop pillow 16, and as the turning angle of the medical pipeline gradually increases, the stop block 6 and the stop pillow 16 will cooperate to continuously lock the medical pipeline, limiting the medical pipeline from continuing to be pushed and moved by the bottom end of the second support arm 3, thereby limiting the medical pipeline from continuing to turn and bend, and achieving a locking stop for the maximum bending and turning angle of the medical pipeline, which can avoid excessive bending, extrusion and deformation of the pipeline, resulting in blockage of liquid or oxygen in the pipeline.

[0043] like Figures 2 to 7 As shown, a second hinge block 14 is fixed to the side of the second support arm 3 away from the first support arm 2, and a shaft rod 18 is passed through the second hinge block 14. Both ends of the shaft rod 18 pass through the side wall of the main frame 1, and a sleeve 12 is fixed to the side wall of the main frame 1 and is sleeved on the end of the shaft rod 18. A torsion spring 19 sleeved on the shaft rod 18 is assembled in the sleeve 12. The axial elastic force of the torsion spring 19 on the shaft rod 18 can be used to make the top end of the second support arm 3 elastically support the medical pipeline, and make the second support arm 3 have an elastic reset function.

[0044] like Figure 1 and Figure 8As shown, this embodiment also includes a mounting bracket 10 for supporting and positioning the main frame 1. Specifically, the mounting bracket 10 includes a vertically arranged first outer tube 21 and a horizontally arranged second outer tube 26. The bottom end of the first outer tube 21 is equipped with a fixing clamp 11 that can be clamped and fixed to one side of the bed. The top of the first outer tube 21 is vertically movably penetrated by a first inner rod 22, and the top of the side wall of the first outer tube 21 is threadedly penetrated by a first positioning bolt 23 for tightly positioning the first inner rod 22. The top of the first inner rod 22 is threadedly inserted with a fastening screw 24, and a sleeve block 25 is movably sleeved on the fastening screw 24. The second outer tube 26 is horizontally fixed to the side wall of the sleeve block 25, and a second inner rod 27 is movably penetrated at one end of the second outer tube 26 away from the sleeve block 25. A screw thread is penetrated on the side wall of the second outer tube 26 away from the sleeve block 25 for pressing the second inner rod 27 against the second inner rod 27. The second positioning bolt 28 is tightly positioned, and the main frame 1 is fixedly assembled on the end of the second inner rod 27 extending outside the second outer tube 26. Through this structural method, the first outer tube 21 is fixed to one side of the patient's bed by using the fixing clamp 11. At this time, the first outer tube 21, the first inner rod 22, the second outer tube 26 and the second inner rod 27 cooperate to support the main frame 1. Among them, by extending and retracting the first inner rod 22 and positioning the first inner rod 22 by screwing the first positioning bolt 23, the height of the main frame 1 can be adjusted. By extending and retracting the second inner rod 27 at the end of the second outer tube 26 and tightening the second positioning bolt 28 to position the second inner rod 27, the extended length of the main frame 1 can be adjusted. By loosening the fastening screw 24, rotating the sleeve block 25 and the sleeve block 25, and tightening the fastening screw 24 again to clamp the sleeve block 25, the orientation of the main frame 1 can be adjusted, thereby improving the flexibility of the fixator.

[0045] The workflow of the technical solution provided by the present invention is as follows:

[0046] The first outer tube 21 is fixed to one side of the patient's bed by using the fixing clamp 11. At this time, the first outer tube 21, the first inner rod 22, the second outer tube 26 and the second inner rod 27 cooperate to support the main frame 1. The height of the main frame 1 can be adjusted by extending and retracting the first inner rod 22 and positioning the first inner rod 22 by screwing the first positioning bolt 23. The extended length of the main frame 1 can be adjusted by extending and retracting the second inner rod 27 at the end of the second outer tube 26 and tightening the second positioning bolt 28 to position the second inner rod 27. The sleeve block 25 and the sleeve block 25 are rotated by loosening the fastening screw 24 and then tightening the sleeve block 25. Tighten the fastening screws 24 to clamp the sleeve block 25 in place, so as to adjust the orientation of the main frame 1. The medical pipeline passes through the first support arm 2 and the second support arm 3. The adjusting plate 8 is pushed by tightening the adjusting bolt 9 to drive the first support arm 2 to move in the main frame 1. The spacing between the first support arm 2 and the second support arm 3 is adjusted to adapt to the size of the medical pipeline. During the spacing adjustment process, the first adapting groove 4 and the second adapting groove 5 opened on the first support arm 2 and the second support arm 3 are used to clamp and limit the medical pipeline. In this way, the first support arm 2 and the second support arm 3 will buckle the medical pipeline to provide support for the medical pipeline.

[0047] This support structure can further protect the bending of the medical pipeline. When the medical pipeline is turned and arranged to be pulled toward the second support arm 3, the curved structure design at the top of the second support arm 3 can provide arc support for the medical pipeline, preventing the medical pipeline from being excessively bent and damaged at the support points of the first support arm 2 and the second support arm 3. Moreover, as the medical pipeline bends toward the second support arm 3, the second support arm 3 rotates adaptively with the medical pipeline, and the bottom end of the second support arm 3 pushes the medical pipeline to move along the arc curved portion of the first support arm 2. As a result, the medical pipeline forms two arc bends between the bottom ends of the first support arm 2 and the second support arm 3 and at the top end of the second support arm 3, which are used to cooperate with the turning arrangement of the medical pipeline, so that the medical pipeline can smoothly transition at the support point during the turning arrangement process, reducing the bending wear of the medical pipeline. Furthermore, due to the arc bending of the first support arm 2 The thickness of the part gradually increases from bottom to top toward the side of the second support arm 3, and then when the second support arm 3 adapts to the rotation of the medical pipeline, the bottom end of the second support arm 3 pushes the medical pipeline to move to the position above the first hinge block 13 of the first support arm 2, forcing the top end of the first support arm 2 to rotate toward the side away from the second support arm 3, and the stop block 6 at the bottom end of the first support arm 2 moves close to the stop pillow 7. During this process, the stop block 6 pushes the medical pipeline against the stop pillow 16, and as the turning angle of the medical pipeline gradually increases, the stop block 6 and the stop pillow 16 cooperate to continuously lock the medical pipeline, limiting the medical pipeline from continuing to be pushed and moved by the bottom end of the second support arm 3, thereby limiting the medical pipeline from continuing to turn and bend, and realizing the locking stop of the maximum bending angle of the medical pipeline, ensuring that the medical pipeline will not be damaged by bending due to excessive bending angle caused by patient activities, and the liquid or oxygen in the pipeline will not be blocked.

[0048] The present invention encompasses any alternatives, modifications, equivalents, and solutions that fall within the spirit and scope of the present invention. To provide a thorough understanding of the present invention, specific details are described in detail below in connection with the preferred embodiments of the present invention, but those skilled in the art will be able to fully understand the present invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of the present invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0049] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
