[0006] The clamping mechanism includes a cylinder inserted into and rotatably connected to one side of the shell. The cylinder is equipped with an anti-collision mechanism. A bidirectional lead screw is fixedly connected to the inner end of the cylinder. Two symmetrically arranged nut blocks are threaded onto the bidirectional lead screw.

[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This is a device for fixing an IV stand for critically ill patients used in CT scans. By setting up a clamping mechanism, the IV stand is vertically inserted into two sets of arc-shaped clamps. Rotating the cylinder drives the bidirectional lead screw to rotate. At this time, the two nut blocks are forced to move towards each other, causing the two sets of sliding sleeves fixed to the two sets of connecting rods to move towards each other on the two support rods. This, in turn, causes the two sets of arc-shaped clamps to clamp and fix the IV stand. The fixation is reliable, saves manpower, is simple to operate, and is convenient for CT scans.
[0015] 2. This is a fixation device for an infusion stand for critically ill patients used in CT scans. By incorporating an anti-collision mechanism, when the cylinder needs to be rotated to drive the bidirectional lead screw, firstly, the push rod fixed to the rotating block is displaced, which in turn pushes the T-shaped block to move. At this time, the return spring is stretched and generates a contraction force until the T-shaped block is inserted into the T-groove. Then, rotating the rotating block drives the cylinder to rotate, which in turn drives the bidirectional lead screw to rotate. Conversely, when the rotating block is released, the return spring's elastic force causes the T-shaped block to separate from the T-groove. Therefore, even if medical personnel accidentally touch the rotating block, the T-shaped block fixed to the push rod will simply rotate freely within the cylinder, preventing the cylinder from rotating and thus avoiding damage to the stability of the arc-shaped clamp on the infusion stand due to accidental contact.
[0016] 3. This is a fixation device for an infusion stand for critically ill patients used in CT scans. By setting a spring-loaded latching mechanism, when the position of the slider column needs to be adjusted according to usage requirements, simply press the latch block to move it down into the cavity. At this time, the compression spring is squeezed and contracts to generate elastic force until the latch block is completely separated from the latch hole. At this point, the displacement of the slider column is no longer restricted, and the slider column can be moved in the cylindrical slide rail to achieve position adjustment of the plate shell. This facilitates the position adjustment of the infusion stand during CT scans of critically ill patients, avoiding interference with the CT scan. Attached Figure Description

[0025] Please see Figures 1 to 6 In this practical embodiment, a fixation device for an infusion stand for critically ill patients used in CT scans includes a CT bed 1. A fixing strip 2 is fixedly connected to one side of the CT bed 1. A cylindrical slide rail 3 is fixedly connected to the side of the fixing strip 2 away from the CT bed 1. A slider column 4 is slidably connected inside the cylindrical slide rail 3. The slider column 4 can be moved in the cylindrical slide rail 3 to adjust the position of the plate shell 8, thereby facilitating the position adjustment of the infusion stand during CT scans of critically ill patients and avoiding interference with the CT scan. A spring latching mechanism is provided in the slider column 4. The upper side wall of the cylindrical slide rail 3 has equally spaced latching holes 5. One end of the spring latching mechanism is inserted into its corresponding latching hole 5. A connecting plate 6 is fixedly connected to the front side wall of the slider column 4. A sliding opening 7 is provided on the front side wall of the cylindrical slide rail 3. One end of the connecting plate 6 passes through the sliding opening 7 and is fixedly connected to the plate shell 8. A clamping mechanism is provided on the plate shell 8.
[0026] The clamping mechanism includes a cylinder 9 inserted into and rotatably connected to one side of the shell 8. The cylinder 9 is equipped with an anti-collision mechanism. A bidirectional lead screw 10 is fixedly connected to the inner end of the cylinder 9. Two symmetrically arranged nut blocks 11 are threaded onto the bidirectional lead screw 10. Two sets of symmetrically arranged connecting rods 12 are fixedly connected to both sides of the two nut blocks 11. Two symmetrically arranged support rods 13 are fixedly connected to the shell 8. Two sets of symmetrically arranged sliding sleeves 14 are fitted onto the two support rods 13. One end of each of the two sets of connecting rods 12 is fixedly connected to one of the two sets of sliding sleeves 14. Two sets of movable frames 15 are fixedly connected to the front sidewalls of the two sets of sliding sleeves 14. Two slots 16 are opened on the front side wall of the cylinder 8. Two sets of movable frames 15 pass through the two slots 16 and are fixedly connected to two sets of arc-shaped clamps 17. The infusion stand is vertically inserted into the two sets of arc-shaped clamps 17. The cylinder 9 is rotated, which drives the bidirectional screw 10 to rotate. Since the bidirectional screw 10 is threadedly connected to two nut blocks 11, the two nut blocks 11 are forced to move towards each other. This causes the two sets of sliding sleeves 14, which are fixed to the two sets of connecting rods 12, to move towards each other on the two support rods 13. This, in turn, causes the two sets of arc-shaped clamps 17 to clamp and fix the infusion stand. The fixation is reliable, saves manpower, is simple to operate, and is convenient for CT scanning.
[0027] like Figure 5 As shown: The anti-collision mechanism includes a push rod 18 inserted into and slidably connected to the outer end of the cylinder 9. A rotating block 19 is fixedly connected to the outer end of the push rod 18, and a T-shaped block 20 is fixedly connected to the inner end of the push rod 18. A return spring 21 is rotatably connected to the inner wall of the cylinder 9 via a rotating component. One end of the return spring 21 is fixedly connected to the T-shaped block 20. The return spring 21 is sleeved on the outer side of the push rod 18. A T-shaped groove 22 matching the T-shaped block 20 is opened on the inner bottom wall of the cylinder 9. When it is necessary to rotate the cylinder 9 to drive the bidirectional lead screw 10 to rotate, firstly, the push rod 18 fixed to the rotating block 19 is displaced, and then the T-shaped block 20 is pushed. When the T-block 20 is displaced, the return spring 21 is stretched and generates a contraction force until the T-block 20 is inserted into the T-groove 22. At this time, when the rotating block 19 is rotated, the cylinder 9 can be rotated, which in turn drives the bidirectional lead screw 10 to rotate. Conversely, when the rotating block 19 is released, the elastic force of the return spring 21 drives the T-block 20 to separate from the T-groove 22. At this time, even if medical staff accidentally touch the rotating block 19, the T-block 20 fixed with the push rod 18 can be driven to rotate freely in the cylinder 9 without driving the cylinder 9 to rotate, thus avoiding damage to the firmness of the arc-shaped clamp 17 in clamping the infusion stand due to accidental contact.
[0028] like Figure 5 As shown: The two end sidewalls of the T-shaped block 20 abut against the inner wall of the cylinder 9 and can be rotatably connected, which facilitates the displacement or rotation of the T-shaped block 20 in the cylinder 9.
[0029] like Figure 4As shown: The support rod 13 is cylindrical in shape, and the outer wall of the support rod 13 is slidably connected to the inner wall of the through hole of the sliding sleeve 14, which facilitates the displacement of the sliding sleeve 14.
[0030] like Figure 2 and Figure 6 As shown: The spring-loaded latching mechanism includes a cavity 23 formed in the slider column 4. A compression spring 24 is fixedly connected to the inner bottom wall of the cavity 23. A latching block 25 is fixedly connected to the upper end of the compression spring 24. The upper end of the latching block 25 passes through the slider column 4 and is inserted into its corresponding latching hole 5. When it is necessary to adjust the position of the slider column 4 according to the usage requirements, simply press the latching block 25 down and retract it into the cavity 23. At this time, the compression spring 24 is squeezed and contracted to generate elastic force until the latching block 25 is completely separated from the latching hole 5. At this time, the displacement of the slider column 4 is no longer restricted, and the slider column 4 can be moved in the cylindrical slide rail 3 to realize the position adjustment of the plate shell 8. This facilitates the position adjustment of the infusion stand when critically ill patients undergo CT scans, avoiding interference with the CT scan.
[0031] like Figure 6 As shown: The inner wall of cavity 23 is slidably connected to the outer wall of block 25, making the sliding displacement of block 25 more stable.
[0032] like Figure 2 As shown: Several reinforcing blocks 26 are fixedly connected at equal intervals at the connection between the fixing strip 2 and the cylindrical slide rail 3, making the connection between the fixing strip 2 and the cylindrical slide rail 3 more secure.
[0033] Working principle: When a critically ill patient needs to be fixed in place during a CT scan, the infusion stand is vertically inserted into the two sets of arc-shaped clamps 17. Rotating the cylinder 9 causes the bidirectional lead screw 10 to rotate. Since the bidirectional lead screw 10 is threadedly connected to two nut blocks 11, the two nut blocks 11 are forced to move towards each other, causing the two sets of sliding sleeves 14, which are fixed to the two sets of connecting rods 12, to move towards each other on the two support rods 13. This, in turn, causes the two sets of arc-shaped clamps 17 to hold the infusion stand in place. The fixation is secure, saves manpower, is simple to operate, and is convenient for CT scans.
[0034] When the cylinder 9 needs to be rotated to drive the bidirectional lead screw 10 to rotate, firstly, the push rod 18 fixed to the rotating block 19 is pushed to move, and then the T-shaped block 20 is pushed to move. At this time, the return spring 21 is stretched and generates a contraction force until the T-shaped block 20 is inserted into the T-shaped groove 22. At this time, when the rotating block 19 is rotated, the cylinder 9 can be rotated, and then the bidirectional lead screw 10 can be rotated. Conversely, when the rotating block 19 is released, the elastic force of the return spring 21 is used to drive the T-shaped block 20 to separate from the T-shaped groove 22. At this time, even if the medical staff accidentally touches the rotating block 19, the T-shaped block 20 fixed to the push rod 18 can be driven to rotate freely in the cylinder 9, and the cylinder 9 will not be rotated, thus avoiding the damage to the firmness of the arc-shaped clamp 17 in clamping the infusion stand due to accidental contact.
[0035] When the position of the slider column 4 needs to be adjusted according to usage requirements, simply press the locking block 25 down to retract into the cavity 23. At this time, the compression spring 24 is squeezed and contracted to generate elastic force until the locking block 25 is completely separated from the locking hole 5. At this time, the displacement of the slider column 4 is no longer restricted, and the slider column 4 can be moved in the cylindrical slide rail 3 to realize the position adjustment of the plate shell 8. This facilitates the position adjustment of the infusion stand when critically ill patients undergo CT scans, avoiding interference with the CT scan.
[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
