Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to an intubation fixator for the intensive care unit. Background Art

[0002] In the intensive care unit (ICU), intubation is a crucial medical procedure. Through tracheal intubation, it is possible to maintain the patient's ventilation, ensure the patency of the respiratory tract, avoid serious consequences such as asphyxia and hypoxia caused by airway obstruction, improve the ventilation function, provide effective artificial ventilation for patients with respiratory failure, asphyxia, etc., maintain the patient's vital signs, prevent aspiration, reduce the risk of pulmonary infection, provide conditions for drug treatment, enable the drug to act directly on the respiratory tract, and improve the treatment effect. Through gastric tube intubation, gastrointestinal decompression, prevention of aspiration, nutritional support, drug administration, etc. can be carried out on the patient; through ventricular drainage tube intubation, it is possible to drain fluid, reduce the irritation of the meninges by blood, reduce intracranial pressure, and promote infection control, etc.; through the insertion of a thoracic drainage tube, it is possible to remove free air or blood that may cause the patient to have difficulty breathing, promote lung expansion, and monitor the situation of the drained fluid; through the insertion of an abdominal drainage tube, it is possible to drain the pus, blood, and fluid accumulated in the abdominal cavity to the outside of the body, which has a therapeutic or preventive effect. Thus, intubation treatment is crucial for maintaining the patient's life, improving the ventilation condition, and performing related treatments.

[0003] Currently, during the intubation treatment of patients, since it is difficult to keep the angle at which the tube is inserted into the patient's body aligned and horizontal with the angle at which the tube is connected to the treatment instrument and equipment, the tube will inevitably bend and fold. When the tube is overly bent and folded, it will cause the blockage of the liquid or oxygen in the tube, affecting the treatment of the patient. Therefore, the present invention provides an intubation fixator for the intensive care unit to meet the needs. Summary of the Invention

[0015] Optionally, the mounting bracket includes a first outer tube disposed vertically and a second outer tube disposed horizontally. A fixing clip capable of being clamped and fixed to one side of the hospital bed is assembled at the bottom end of the first outer tube. A first inner rod is vertically and movably inserted through the top end of the first outer tube.

[0038] As Figures 1 to 4 shown, an intubation fixator for the intensive care unit according to an embodiment of the present invention includes a main frame body 1; a second support arm 3 hingedly mounted in the main frame body 1; a first support arm 2 hingedly mounted in the main frame body 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 in 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 towards the side away from the first support arm 2. In this structural manner, after the main frame body 1 is assembled and fixed, by using the first support arm 2 to approach the second support arm 3, the medical pipeline can be clamped to achieve the positioning and support of the medical pipeline. When the medical pipeline needs to be bent and turned, the curved structure design at the top end of the second support arm 3 can provide an arc-shaped 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 the phenomenon of liquid or oxygen blockage in the pipeline.

[0039] As Figures 1 to 4 shown, an adjusting plate 8 is movably arranged in the main frame body 1, the adjusting plate 8 is slidably attached to the inner side wall of the main frame body 1, the adjusting plate 8 is located on the side of the first support arm 2 away from the second support arm 3 and is used for the hinged installation of the first support arm 2, and an adjusting bolt 9 is threadedly penetrated through the side wall of the main frame body 1 close to the adjusting plate 8. The adjusting bolt 9 is rotatably hinged to the adjusting plate 8. By screwing the adjusting bolt 9, the adjusting 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, so as to adapt to the size of the medical pipeline and at the same time be used to clamp the medical pipeline between the first support arm 2 and the second support arm 3.

[0040] As Figures 2 to 7 shown, on the opposite sides of the first support arm 2 and the second support arm 3 facing each other, a first fitting groove 4 and a second fitting groove 5 are respectively formed, which can accommodate the medical pipeline to be embedded, so that the first support arm 2 and the second support arm 3 can support the medical pipeline in a loop. An auxiliary pulley 20 is installed at the bottom end of the second support arm 3. During the rotation of the second support arm 3 to cooperate with the turning arrangement of the medical pipeline, the bottom end of the second support arm 3 can roll and push against the medical pipeline by using the auxiliary pulley 20, reducing the wear on the medical pipeline.

[0041] As Figures 2 to 7 shown, the hinge axes of the first support arm 2 and the second support arm 3 are in the same horizontal position, and the bending center of the first support arm 2 and the hinge axis of the second support arm 3 are in the same horizontal position. A first hinge block 13 is arranged at the middle position of the surface of the arc bending part of the first support arm 2 facing the adjusting plate 8, and the first hinge block 13 is hinged to the adjusting plate 8. Through the above structural method, as the medical pipeline bends towards the second support arm 3, the second support arm 3 rotates adaptively following the medical pipeline, and the bottom end of the second support arm 3 pushes against the medical pipeline to move along the arc bending part of the first support arm 2. Thus, 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 points during the turning arrangement process, reducing the bending wear of the medical pipeline.

[0042] As Figures 2 to 7As shown, the bottom end of the first support arm 2 extends vertically downward and is fixedly connected with a stop block 6. On one side of the bottom of the main frame 1 close to the second support arm 3, there is a stop pillow 7 opposite to the stop block 6. The stop pillow 7 includes a fixing plate 15 fixed to the bottom of the main frame 1. The bottom end of the fixing plate 15 bends towards the stop block 6 and is connected with a stop pillow block 16. Between the vertical arm of the fixing plate 15 and the bottom of the main frame 1, there is a reinforcing plate 17 connected. The reinforcing plate 17 is in a triangular structure and is used for reinforcing the fixing plate 15. The stop pillow block 16 is made of rubber material. The bottom of the first hinge block 13 is set in a rectangular structure, and the top of the first hinge block 13 facing the adjusting plate 8 is set in a semi-circular structure. The thickness of the arc bending part of the first support arm 2 gradually increases from bottom to top towards the second support arm 3. The stop block 6 has an inclined surface facing away from the stop pillow block 16. Through the above structural means, when the bottom end of the second support arm 3 pushes against the medical pipeline and is at the part where the first support arm 2 is lower than the first hinge block 13, the rectangular surface at the bottom of the first hinge block 13 abuts against the adjusting plate 8, restricting 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 the position above the first hinge block 13 of the first support arm 2, combined with the arc structure at the top of the first hinge block 13, and in addition, the thickness of the arc bending part of the first support arm 2 gradually increases from bottom to top towards the second support arm 3, it will force the top end of the first support arm 2 to rotate towards the side away from the second support arm 3. The stop block 6 at the bottom end of the first support arm 2 then moves close to the stop pillow 7, and the stop block 6 immediately pushes against the medical pipeline and abuts it against the stop pillow block 16. And as the turning angle of the medical pipeline gradually increases, the cooperation between the stop block 6 and the stop pillow block 16 continuously locks the medical pipeline, restricting the continuous pushing and movement of the medical pipeline by the bottom end of the second support arm 3, thereby restricting the continuous turning and bending of the medical pipeline, realizing the locking and stopping of the maximum bending turning angle of the medical pipeline, and avoiding the phenomenon that the liquid or oxygen in the pipeline is blocked due to excessive bending and extrusion deformation of the pipeline.

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

[0044] As Figure 1 and Figure 8As shown in the figure, this embodiment further 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. A fixing clip 11 capable of being clamped and fixed on one side of the hospital bed is assembled at the bottom end of the first outer tube 21. A first inner rod 22 is vertically and movably inserted through the top end of the first outer tube 21. A first positioning bolt 23 for tightly pressing and positioning the first inner rod 22 is threadedly inserted through the top side wall of the first outer tube 21. A fastening screw 24 is threadedly inserted into the top end of the first inner rod 22. A sleeve block 25 is movably sleeved on the fastening screw 24. The second outer tube 26 is horizontally fixed on the side wall of the sleeve block 25. A second inner rod 27 is movably inserted through one end of the second outer tube 26 away from the sleeve block 25. A second positioning bolt 28 for tightly pressing and positioning the second inner rod 27 is threadedly inserted through the side wall of the second outer tube 26 away from the sleeve block 25. The main frame 1 is fixedly assembled at one 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 on one side of the patient's hospital bed by using the fixing clip 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 adjusting the length of the first inner rod 22 and screwing the first positioning bolt 23 to position the first inner rod 22, 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 cooperating with screwing the second positioning bolt 28 to tighten and 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 then screwing the fastening screw 24 again to clamp and position the sleeve block 25, the orientation of the main frame 1 can be adjusted, improving the flexibility of the fixator.

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

[0046] Fix the first outer tube 21 on one side of the patient's hospital bed by using the fixing clip 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 telescoping the first inner rod 22 and turning the first positioning bolt 23 to position the first inner rod 22, the height of the main frame 1 can be adjusted. By telescoping the second inner rod 27 at the end of the second outer tube 26 and cooperating with turning the second positioning bolt 28 to tighten and position the second inner rod 27, the extended length of the main frame 1 can be adjusted. By loosening the fastening screw 24 to rotate the sleeve block 25 and the sleeve block 25, and then tightening the fastening screw 24 again to clamp and position the sleeve block 25, the orientation of the main frame 1 can be adjusted. The medical pipeline passes through between the first support arm 2 and the second support arm 3. By turning the adjusting bolt 9 to push the adjusting plate 8 to drive the first support arm 2 to move in the main frame 1, the distance between the first support arm 2 and the second support arm 3 can be adjusted to adapt to the size of the medical pipeline. During the distance adjustment process, the medical pipeline is clamped and limited by the first matching groove 4 and the second matching groove 5 formed on the first support arm 2 and the second support arm 3. Thus, the first support arm 2 and the second support arm 3 loop the medical pipeline to provide support for the medical pipeline.

[0047] The support structure can further protect the bending of the medical pipeline. When the medical pipeline is bent towards the second support arm 3 under traction during the turning arrangement, the bending structure design at the top of the second support arm 3 can provide an arc-shaped 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 towards the second support arm 3, the second support arm 3 rotates adaptively following the medical pipeline, and the bottom end of the second support arm 3 pushes against the medical pipeline to move along the arc-shaped bending part of the first support arm 2. Thus, the medical pipeline forms 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 is used to cooperate with the turning arrangement of the medical pipeline, enabling the medical pipeline to smoothly transition at the support points during the turning arrangement, reducing the bending and wear of the medical pipeline. Further, since the thickness of the arc-shaped bending part of the first support arm 2 gradually increases from bottom to top towards the second support arm 3, when 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 to a position above the first hinge block 13 of the first support arm 2, it forces the top end of the first support arm 2 to rotate towards 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 closer to the stop pillow 7. During this process, the stop block 6 pushes the medical pipeline against the stop pillow block 16, and as the turning angle of the medical pipeline gradually increases, the stop block 6 and the stop pillow block 16 cooperate to continuously lock the medical pipeline, restricting the medical pipeline from being further pushed and moved by the bottom end of the second support arm 3, thereby restricting the medical pipeline from further turning and bending, achieving the locking and stopping of the maximum bending angle of the medical pipeline, and ensuring that the medical pipeline will not be bent and damaged due to excessive bending caused by patient movement and the phenomenon of liquid or oxygen blockage in the pipeline.

Additionally, to avoid unnecessary confusion to the essence of the present invention, well-known methods, processes, procedures, components, and circuits are not described in detail.
