DETAILED DESCRIPTION

[0038] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in an exemplary manner in conjunction with the accompanying drawings.

[0039] See also Figures 1 to 11 , the present invention provides a technical solution: a pediatric infusion set anti-falling mechanism, comprising a mobile vehicle 1, wherein a universal wheel for driving the mobile vehicle 1 to move is arranged below the mobile vehicle 1;

[0040] The mobile vehicle 1 can be moved by means of the universal wheel structure so that the patient can receive infusion in different places.

[0041] A storage column 2, wherein the storage column 2 is fixedly mounted above the mobile vehicle 1, and a lifting column 3 is arranged above the storage column 2, and the lifting column 3 is vertically slidably connected to the storage column 2;

[0042] The structure of the storage column 2 allows the lifting column 3 to be raised or lowered. When the mobile vehicle 1 is moving, the height of the lifting column 3 is lowered, so that the overall center of gravity of the mobile vehicle 1 is lowered to avoid rollover.

[0043] A plurality of brackets 39 are provided on the top of the lifting column 3, and a protective component 6 is provided on the bracket 39, and the protective component 6 is clamped with the bracket 39;

[0044] The protection assembly 6 is installed on the lifting column 3 through the structure of the bracket 39 .

[0045] The protection assembly 6 includes a bottom plate 61 and a top plate 62, and an infusion bottle 10 is installed between the bottom plate 61 and the top plate 62;

[0046] The infusion bottle 10 is installed in the protective assembly 6 through the structure of the bottom plate 61 and the top plate 62, so as to avoid the problem of the infusion bottle 10 being easily loosened when installed on the bracket 39.

[0047] A telescopic rod 7 is further provided between the bottom plate 61 and the top plate 62, and the telescopic rod 7 adjusts the height between the bottom plate 61 and the top plate 62, and at the same time, the telescopic rod 7 clamps and fixes the infusion bottle 10 therebetween;

[0048] The expansion disk 8 is disposed on the bottom plate 61 , and the expansion disk 8 is rotatably connected to the bottom plate 61 . The expansion disk 8 drives the telescopic rod 7 to contract inward or expand outward.

[0049] Through the structure of the telescopic rod 7, the bottom plate 61 and the top plate 62 move toward each other to clamp and fix the infusion bottle 10 in the vertical direction, and under the rotation of the expansion disk 8, the telescopic rod 7 expands outward, which facilitates the installation of the infusion bottle 10 in the protective assembly 6 along the gap of the telescopic rod 7, and the expansion disk 8 controls the telescopic rod 7 to retract inward to clamp and fix the infusion bottle 10 in the horizontal direction.

[0050] A handle 31 is fixedly connected to the bottom of the lifting column 3, and an anti-slip pad is provided on the side wall of the handle 31. A first screw rod 32 is fixedly connected to the lower end of the handle 31. The first screw rod 32 is inserted into the storage column 2, and the first screw rod 32 is threadedly connected to the inner wall of the storage column 2.

[0051] By turning the handle 31, the first screw rod 32 and the storage column 2 rotate relative to each other, and the lifting column 3 is controlled to rise or fall above the storage column 2. When the mobile vehicle 1 moves, the lifting column 3 is lowered to the lowest point to lower the overall center of gravity of the mobile vehicle 1 for transportation. After the mobile vehicle 1 is stationary, the height of the lifting column 3 is controlled to make it suitable for children of different heights.

[0052] A limiting groove 33 is provided in the middle of the first screw rod 32, and a movable groove 34 is provided below the limiting groove 33. The limiting groove 33 is communicated with the movable groove 34, and a limiting column 35 is slidably connected in the limiting groove 33 and the movable groove 34. The cross-sections of the limiting groove 33 and the limiting column 35 are both set to be square, and the movable groove 34 is a cylindrical groove with a diameter larger than the distance between the diagonals of the limiting groove 33.

[0053] The lower part of the limiting column 35 is installed on the rotating shaft 36, and the rotating shaft 36 is rotatably connected to the bottom inner wall of the storage column 2. A second screw rod 37 is installed below the rotating shaft 36, and the second screw rod 37 passes through the bottom of the storage column 2 and the lower part of the mobile vehicle 1. The second screw rod 37 rotates synchronously with the limiting column 35. A movable column 42 is sleeved below the second screw rod 37, and the inner wall of the movable column 42 is threadedly connected to the second screw rod 37. The movable column 42 is arranged in the mobile vehicle 1. The movable column 42 and its sliding track in the mobile vehicle 1 are both set to be square, and the lower end of the movable column 42 passes through the bottom of the mobile vehicle 1. The end of the movable column 42 is fixedly connected to the brake plate 4, and the lower surface of the brake plate 4 is provided with a friction plate 41 to increase the friction between the ground.

[0054] When the upper end of the limiting column 35 is in the limiting groove 33, the rotation of the first screw rod 32 will drive the limiting column 35 to rotate, so that the second screw rod 37 rotates along with it, that is, the lifting column 3 moves upward within a certain range and the second screw rod 37 and the first screw rod 32 rotate synchronously. Since the second screw rod 37 is threadedly connected to the movable column 42, and its sliding trajectory limits the rotation of the movable column 42, the movable column 42 slides vertically downward, driving the brake plate 4 to touch the ground, and the friction between the brake plate 41 and the ground is increased to prevent the moving vehicle 1 from being displaced during use. After the lifting column 3 rises to a certain height, the upper end of the limiting column 35 enters the movable groove 34. At this time, the rotation of the first screw rod 32 will not drive the second screw rod 37 to rotate, and at this time the brake plate 4 reaches the lowest point, thereby achieving the purpose of stopping the movement of the moving vehicle 1.

[0055] A top block 38 is fixedly connected to the top of the lifting column 3, and a plurality of brackets 39 are fixedly connected to the side walls of the top block 38. The brackets 39 are provided with grooves. A hanging plate 63 is fixedly connected to the top of the top plate 62, and the hanging plate 63 is snapped into the groove of the bracket 39 to enable the protective component 6 to be snapped into the bracket 39.

[0056] The protection assembly 6 is fixed to the upper end of the lifting column 3 by the clamping structure of the hanging plate 63 and the bracket 39, so that the lifting column 3 rises or falls, driving the protection assembly 6 and the infusion bottle 10 inside it to move up and down.

[0057] A plurality of slide grooves 64 are provided in the bottom plate 61, a slider 73 is horizontally slidably connected in the slide groove 64, a slide column 71 is fixedly connected above the slide column 73, the slide column 71 passes through the top of the bottom plate 61, the telescopic rod 7 is sleeved above the slide column 71, the telescopic rod 7 is vertically slidably connected to the slide column 71, and the upper end of the telescopic rod 7 is horizontally slidably connected to the top plate 62.

[0058] A second spring 72 is provided between the telescopic rod 7 and the sliding column 71, the upper end of the second spring 72 is fixedly connected to the top inner wall of the telescopic rod 7, and the lower end of the second spring 72 is fixedly connected to the sliding column 71. A plurality of expansion grooves 81 are provided on the surface of the expansion disk 8, and the number of the expansion grooves 81 is consistent with the number of the sliding columns 71. The sliding column 71 vertically passes through the expansion grooves 81, and the sliding column 71 is slidably connected to the expansion grooves 81. A plurality of ball blocks 87 are fixedly connected to the inner side of the expansion disk 8, and a rotating groove is provided on the upper inner side of the bottom plate 61. The ball block 87 is inserted into the rotating groove of the bottom plate 61, and the ball block 87 rotates in the rotating groove.

[0059] First, the bottom plate 61 is pulled in the opposite direction of the top plate 62, so that the telescopic rod 7 slides in the direction away from the sliding column 71, that is, the distance between the bottom plate 61 and the top plate 62 reaches the maximum value. At this time, through the action of the expansion disk 8, the multiple telescopic rods 7 are expanded outward, so that the distance between each telescopic rod 7 is increased, that is, the infusion bottle 10 can pass through the gap between the telescopic rods 7, and the infusion bottle 10 is moved between the bottom plate 61 and the top plate 62, and the bottle mouth of the infusion bottle 10 is facing the direction of the bottom plate 61. At this time, under the elastic force of the second spring 72, the telescopic rod 7 and the sliding column 71 are tightened, that is, the bottom plate 61 and the top plate 62 move toward each other, and the infusion bottle 10 is clamped and fixed in the up and down directions. The expansion disk 8 is rotated, so that the expansion groove 81 guides the multiple sliding columns 71 to retract inward, so that the telescopic rod 7 clamps and fixes the side wall of the infusion bottle 10.

[0060] A gear ring 82 is fixedly connected to the lower outer side of the expansion disk 8, and a gear 83 is rotatably installed on the upper side of one side of the base plate 61. The gear 83 is meshed with the gear ring 82 for transmission. The lower side of the gear 83 is arranged on a rotating column 84, and the rotating column 84 is rotatably connected to the inner wall of the base plate 61. A clockwork spring 85 is installed on the lower outer side of the rotating column 84, and the center of the clockwork spring 85 is fixed to the side wall of the rotating column 84. A connecting rope 86 is fixedly connected to the outer end of the clockwork spring 85, and the connecting rope 86 passes through the side wall of the base plate 61. The other end of the connecting rope 86 is fixedly connected to the lower side of one side of the top plate 62.

[0061] When the bottom plate 61 and the top plate 62 are pulled apart in opposite directions, the connecting rope 86 pulls the clockwork spring 85 to contract, driving the rotating column 84 to rotate in one direction, and the gear 83 drives the gear ring 82 to rotate, so that the expansion disk 8 drives the sliding column 71 to slide outward. When the opposite direction force between the bottom plate 61 and the top plate 62 disappears, under the elastic force of the second spring 72, the bottom plate 61 and the top plate 62 slide toward each other, so that the tension of the connecting rope 86 on the clockwork spring 85 is reduced until it disappears. At this time, the clockwork spring 85 drives the rotating column 84 to rotate in the opposite direction, that is, the gear 83 rotates in the opposite direction. Under the meshing transmission action of the gear 83 and the gear ring 82, the expansion groove 81 drives the sliding column 71 to contract inwardly until the telescopic rod 7 clamps and positions the side wall of the infusion bottle 10.

[0062] An infusion component 9 is installed in the upper middle part of the bottom plate 61, the expansion plate 8 is sleeved on the outside of the infusion component 9 and rotates with the infusion component 9 as the center, a cannula 91 is fixedly installed on the inner side of the infusion component 9, the upper end of the cannula 91 is provided with a sharp mouth, the cannula 91 is plugged into the infusion bottle 10, and a lifting plate 92 is sleeved on the outer side of the cannula 91, and the lifting plate 92 is vertically slidably connected to the infusion component 9.

[0063] Sealing pads 93 are respectively provided on the top and inner and outer sides of the lifting plate 92, so that the lifting plate 92 can slide in a sealed manner with the infusion component 9 and the cannula 91. The part of the cannula 91 located below the lifting plate 92 is sleeved with a third spring 94, one end of the third spring 94 is fixedly connected to the bottom of the lifting plate 92, and the other end of the third spring 94 is fixedly connected to the bottom inner wall of the infusion component 9.

[0064] Under the elastic force of the second spring 72, the bottom plate 61 and the top plate 62 squeeze the infusion bottle 10 inward to ensure that the sharp end of the cannula 91 can be inserted into the infusion bottle 10. Under the elastic force of the third spring 94, the lifting plate 92 can press against the bottle mouth of the infusion bottle 10, and the sealing performance of the sealing gasket 93 is utilized to prevent the liquid medicine in the infusion bottle 10 from flowing out along the side wall of the cannula 91.

[0065] A telescopic tube 95 is installed at the lower middle part of the bottom plate 61 , the upper end of the telescopic tube 95 is connected to the cannula 91 , the lower end of the telescopic tube 95 is fixedly connected to a drip pot 96 , and the lower part of the drip pot 96 is connected to the infusion catheter.

[0066] The cannula 91 guides the liquid medicine in the infusion bottle 10 into the telescopic tube 95 , and controls the flow rate of the liquid medicine downward along the infusion catheter below the drip pot 96 through the drip pot 96 .

[0067] A fixing ring 52 is installed on the side wall of the lifting column 3, and a stud is arranged on one side of the fixing ring 52. The fixing ring 52 is fixed to the lifting column 3 by the abutment between the stud and the side wall of the lifting column 3. A lifting ring 5 is arranged above the fixing ring 52. The lifting ring 5 is sleeved on the lifting column 3. The lifting ring 5 is vertically slidably connected to the lifting column 3. A plurality of elastic clips 51 are arranged on the side wall of the lifting ring 5. The elastic clips 51 are clamped and fixed to the drip pot 96. A first spring 53 is arranged below the lifting ring 5, one end of the first spring 53 is fixedly connected to the lifting ring 5, and the other end of the first spring 53 is fixedly connected to the fixing ring 52.

[0068] The height of the lifting column 3 is adjusted according to the height of the child, and the drip pot 96 is stuck in the elastic clip 51. Under the elastic force of the first spring 53, the lifting ring 5 drives the drip pot 96 to slide upward, so that the telescopic tube 95 remains in a contracted state. After the fixing ring 52 is fixed on the lifting column 3, the length of the infusion catheter below the drip pot 96 is moderate to avoid the catheter being too long and the wire twisting phenomenon when the child is active. When the child moves within a certain range, the lifting ring 5 will move downward and the telescopic tube 95 will be extended to ensure that the infusion tube will not be pulled if the length is not enough, which will cause the infusion set to fall off and cause injuries.
