[0047] First, the user can hang the infusion bottle on the hook 42. After hanging, the user pulls the pull plate 61 to the right. The pull plate 61 moves to the right, driving the first connecting frame 63 to move to the right. The second return spring 62 is compressed. The first connecting frame 63 moves to the right, driving the first pull rope 68 to move to the right. When moving to the right, the first pull rope 68 pulls the hinge block 67 to swing. The first torsion spring 66 is compressed. When the hinge block 67 swings, it drives the second clamping block 610 and the third return spring 69 to move together. When moving, the second clamping block 610 is squeezed by the fixed block 65 and moves toward the hinge block 67. The third return spring 69 is compressed. When the second clamping block 610 moves to no longer contact with the fixed block 65, the second clamping block 610 is reset under the action of the third return spring 69. When the hinge block 67 swings to a certain extent, the infusion tube can be placed between the two fixed blocks 65 and the two hinge blocks 67, and the infusion tube is located on the positioning block 54. After placement, the first connecting frame 63 is released. At this time, the pull plate 61 and the first connecting frame 63 are reset under the action of the second reset spring 62. After the first connecting frame 63 is reset, the first pull rope 68 is no longer pulled. At this time, the hinge block 67 is reversely swung and reset under the action of the first torsion spring 66. When the hinge block 67 swings in the reverse direction, it drives the second clamping block 610 and the third reset spring 69 to move together. When the second clamping block 610 moves to contact with the fixed block 65, the second clamping block 610 continues to move and is squeezed by the fixed block 65 to move toward the hinge block 67. The third reset spring 69 is compressed When the second clamping block 610 moves to its original position, the second clamping block 610 is reset and clamped on the fixed block 65 under the action of the third reset spring 69, thereby sheathing the infusion tube and limiting the infusion tube. Then the doctor inserts the needle into the patient's blood vessel to perform infusion. During the infusion process, the rotating rod 55 can be twisted to drive the squeezing wheel 56 and the toothless ratchet 57 to rotate. When the squeezing wheel 56 rotates, the protruding part thereof will contact the infusion tube. When the protruding part of the squeezing wheel 56 rotates to contact the infusion tube, the squeezing wheel 56 continues to rotate to squeeze the infusion tube through the protruding part thereof, thereby adjusting the flow rate of the liquid medicine in the infusion tube. When the toothless ratchet 57 rotates, it will contact the ratchet block 511. When the toothless ratchet 57 moves to contact the ratchet block 5 After the toothless ratchet 57 contacts with the toothed portion 11, the toothless ratchet 57 continues to rotate and squeezes the ratchet block 511 to move to the right, and the common spring 510 is compressed. When it is adjusted to a suitable position and the toothless ratchet 57 also rotates to no longer squeeze the ratchet block 511, the ratchet block 511 is reset under the action of the common spring 510 to jam the toothless ratchet 57. If the patient wants to move during infusion, the infusion stand can be pulled to move via the moving wheel 1, making it more convenient for the patient to move. In this way, the infusion stand can be used. During use, the flow rate of the liquid medicine in the infusion tube can be adjusted, making it more convenient for the patient to move. When it is necessary to make the squeezing wheel 56 no longer squeeze the infusion tube, the rotating rod 55 is twisted to continue to rotate to drive the squeezing wheel 56 and the toothless ratchet 57 to continue to rotate.When the position without teeth on the toothless ratchet wheel 57 rotates to align with the ratchet block 511, the protruding portion on the squeezing wheel 56 no longer contacts the infusion tube, thereby no longer squeezing the infusion tube. When the infusion tube needs to be taken out, the pull plate 61 is pulled to the right again to take out the infusion tube. After taking it out, the pull plate 61 can be released. When the height needs to be adjusted, the telescopic rod 41 can be pulled upward along the mounting tube 3 for adjustment. When the telescopic rod 41 moves upward, it drives the first clamping block 44 to move upward. When the first clamping block 44 moves upward to contact with the mounting tube 3, the first clamping block 44 continues to move upward and is squeezed by the mounting tube 3 to move toward the inside of the telescopic rod 41. The first return spring 43 is compressed. When a block 44 moves upward to align with another first slot 31, the first block 44 is reset and snapped into the first slot 31 again under the action of the first reset spring 43, and this is repeated. When the telescopic rod 41 is adjusted to a suitable height and the first block 44 is snapped into the first slot 31, the telescopic rod 41 can be loosened. When the telescopic rod 41 needs to be reset, the telescopic rod 41 can be pressed to move downward. When the height of the first mounting block 51 needs to be adjusted, the screw 52 is first twisted to loosen the first mounting block 51 on the telescopic rod 41, and then the first mounting block 51 is pulled up and down along the telescopic rod 41 for adjustment. After the adjustment is completed, the screw 52 is twisted to fix the first mounting block 51 on the telescopic rod 41.

[0048] Example 2

The placing mechanism 7 includes a mounting plate 71, a placing plate 72, a handle 73, a pull rod 74, a clamping plate 75 and a first connecting spring 76. The mounting tube 3 is slidably connected with the mounting plate 71, and the mounting plate 71 can slide on the slide groove 33. The middle part of the mounting plate 71 is connected with a placing plate 72, and the placing plate 72 is used for placing articles.

The handle 73 is connected to the rear side of the top of the placing plate 72, and the pull rod 74 is slidably connected to the rear side of the lower part of the mounting plate 71. Two clamping plates 75 are hingedly connected to the upper part of the pull rod 74. The clamping plate 75 is located in the gap between the mounting plate 71 and the placing plate 72, and the clamping plate 75 abuts against the mounting tube 3. The clamping plate 75 can be clamped into the second clamping groove 32, and a first connecting spring 76 is connected between the rear sides of the two clamping plates 75.

[0050] When the clamping plate 75 is against the mounting tube 3, the first connecting spring 76 is in a compressed state. When the infusion stand is in use, some medical supplies or fruits eaten by the patient can be placed on the placing plate 72. When it is necessary to adjust the height of the mounting plate 71 and the placing plate 72, the handle 73 can be pulled to drive the mounting plate 71 and the placing plate 72 to move up and down along the slide groove 33 for adjustment. When the mounting plate 71 and the placing plate 72 are moved to a suitable height and the clamping plates 75 on the left and right sides are at the same height as the second clamping grooves 32 on the left and right sides, the pull rod 74 can be pushed to move toward the mounting tube 3. When the pull rod 74 moves, it drives the two clamping plates 75 to move together. When the clamping plate 75 moves to align with the second clamping groove 32 When the clamping plate 75 is moved to be disengaged from the second slot 32, the mounting plate 71 and the placement plate 72 can be pulled to move again, and this process is repeated many times to achieve the effect of placing items, and the placement height can be adjusted to facilitate the patient to take the items.

[0051] Example 3

[0052] On the basis of Example 2, Figure 1 , Figure 3 , Fig.13 , Fig.14 , Fig.15 , Fig.16 and Fig.17 As shown, a heating mechanism 8 is also included, and the heating mechanism 8 is used to heat the liquid medicine in the infusion tube. The heating mechanism 8 includes a support frame 81, a heat preservation box 82, a baffle 83, a second torsion spring 84, a hinged plate 85, an extrusion block 86, a pressure rod 87, a connecting rod 88 and a fourth reset spring 89. The front side of the top of the placement plate 72 is connected to the support frame 81, and the top of the support frame 81 is connected to the heat preservation box 82. The front side of the heat preservation box 82 is rotatably connected to two baffles 83, and the two baffles 83 are symmetrically arranged. Two second springs are connected between the two baffles 83 and the heat preservation box 82. A torsion spring 84 and a hinged plate 85 are symmetrically hingedly connected on the left and right sides of the insulation box 82. An extrusion block 86 is slidably connected inside the insulation box 82. The extrusion block 86 is used to extrude the heated items. A pressure rod 87 is slidably connected to the extrusion block 86. The pressure rod 87 can push the extrusion block 86 to move. The pressure rod 87 can slide on the insulation box 82.

The two ends of the two fourth return springs 89 are respectively connected to the left and right sides of the top of the connecting rod 88 and the left and right sides of the bottom of the insulation box 82.

[0053] When placing the infusion tube, the infusion tube can be operated to move into the incubator 82 through the two baffles 83. When moving, the infusion tube squeezes the baffle 83 to swing inward, and the second torsion spring 84 is compressed. When the infusion tube moves to no longer contact with the baffle 83, the infusion tube is already in the incubator 82. At this time, the two baffles 83 are reset under the action of the second torsion spring 84, and then the user can pull the hinged plate 85 on either side to swing, and then the warm baby can be stuffed into the incubator 82 and the warm baby is located between the squeezing block 86 and the infusion tube. After adding, pull the hinged plate 85 to reset, and then the pressure rod 87 can be squeezed to move downward. The downward movement of the pressure rod 87 drives the connecting rod 88 to move downward, and the fourth reset spring 89 is stretched. When the pressure rod 87 moves downward, it can also squeeze the squeezing block 86 to move forward, and the squeezing block 86 can move the warm baby forward when it moves forward. When the pressure relief valve 85 is in place, the pressure relief valve 86 is pulled back to the bottom of the infusion tube and the pressure relief valve 86 is pulled back to the bottom of the infusion tube.

[0054] The insulating box 82 further includes an isolating mechanism 9, which is used to assist the operation of the heating mechanism 8. The isolating mechanism 9 includes a second mounting block 91, a second connecting spring 92, a second connecting frame 93, a guide ring 94, a second pull rope 95, a third pull rope 96 and an isolating arc plate 97. The left and right sides of the bottom of the insulating box 82 are connected to the second mounting blocks 91, and the side of the second mounting blocks 91 on both sides close to each other is connected to the second connecting spring 92, and the ends of the two second connecting springs 92 close to each other are connected to the second connecting frame 93, and the second connecting frame 93 can Sliding at the bottom of the insulated box 82, a second pull rope 95 is connected between the second connecting frames 93 on both sides, guide rings 94 are connected to the left and right sides of the bottom of the insulated box 82, the guide ring 94 is located on the inner side of the second connecting frame 93, the second pull rope 95 passes through the two guide rings 94, the middle part of the second pull rope 95 is connected to the third pull rope 96, the third pull rope 96 is connected to the middle part of the connecting rod 88, the top of the second connecting frame 93 is connected to an isolation arc plate 97, the isolation arc plate 97 is located in the insulated box 82, and the two isolation arc plates 97 can form a cylinder when they are fully in contact.

[0055] When the connecting rod 88 moves downward, it drives the third pull rope 96 to move downward. When the third pull rope 96 moves downward, it pulls the second connecting frames 93 on both sides to approach each other through the second pull rope 95. The guide ring 94 can guide the second pull rope 95. The second connecting spring 92 is stretched. When the second connecting frames 93 on both sides approach each other, they can drive the isolation arc plates 97 on both sides to approach each other. After the isolation arc plates 97 on both sides approach each other, they can be sleeved on the outside of the infusion tube. At this time, the isolation arc plates 97 on both sides form a cylinder. Then, when the warm baby is wrapped, it will be wrapped in the isolation arc plates on both sides. 97 is heated, so as to avoid the hot pack being directly wrapped on the outside of the infusion tube. Because the part wrapped by the hot pack has a certain viscosity, it is easy to stick to the infusion tube if it is directly wrapped on the outside of the infusion tube. When taking it out, it is easy to pull the infusion tube together, which makes it more troublesome to take out the hot pack. It can also play a role when placing other heating items with a certain viscosity. When resetting, the connecting rod 88 no longer pulls the third pull rope 96. At this time, under the action of the second connecting springs 92 on both sides, the second connecting frames 93 on both sides drive the isolation arc plates 97 on both sides to reset, and then the infusion tube can be taken out.

[0056] It also includes a clamping mechanism 10, which can be clamped on a chair or a hospital bed. The clamping mechanism 10 includes a mounting ring 101, a rotating block 102 and a third clamping block 103. The outer arc surface of the mounting plate 71 is connected to the mounting ring 101, and the rotating block 102 is slidably connected inside the mounting ring 101. The rotating block 102 is connected to the third clamping block 103, and the third clamping block 103 can be clamped on a chair or a hospital bed.

[0057] When the patient needs to sit or lie down to rest, the third clamping block 103 can be clamped on a chair or bed. If the third clamping block 103 cannot face the chair or bed, the third clamping block 103 can be pulled to slide along the mounting ring 101 through the rotating block 102 for adjustment. In this way, the infusion stand can be fixed when the patient needs to rest to prevent the displacement of the infusion stand from affecting the infusion.
