[0004] In the above patent, the infusion bottle can slide freely when the patient is receiving an infusion, and the infusion can be adjusted freely and quickly. The specific height and position of the infusion bottle can be changed according to actual usage needs. Since the infusion catheter will be hung on the infusion stand at will during the infusion, passers-by will pull the catheter when moving, and the catheter will easily detach from the infusion bottle, thereby affecting the normal infusion bottle, and it is difficult to protect the connection between the catheter and the infusion bottle during the infusion process.

[0005] Therefore, it is very necessary to design an adjustment mechanism for an emergency department nursing infusion stand that is highly practical and can prevent the catheter from being detached from the infusion bottle after being pulled, thereby affecting normal infusion.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: an adjustment mechanism for an infusion stand for emergency nursing, comprising a base, an anti-pull device and a stabilizing device; wherein a support frame is fixedly installed on the top of the base, and a connecting plate is fixedly installed on the top of the support frame; wherein the anti-pull device comprises a limiting frame, a rubber wheel, an elastic telescopic block, a slide plate, a push rod, a fixing plate, a splint and a positioning block, wherein the limiting frame is fixedly installed on the surface of the support frame, the rubber wheel is rotatably installed inside the limiting frame, the elastic telescopic block is fixedly installed on the surface of the rubber wheel, and the slide plate is slidably installed on the top of the limiting frame The pushing rod is fixedly mounted on the top of the slide, the fixing plate is fixedly mounted inside the limiting frame, the splint is slidably mounted on the top of the fixing plate, a notch is provided on the surface of the fixing plate, and the blocking block is slidably mounted on the surface of the splint, wherein the stabilizing device includes a circular plate and an adsorption assembly, the pushing rod moves upward to push the blocking block to move upward, the blocking block moves upward to disengage from the notch, so that the blocking block releases the limitation on the splint, and the splint moves toward each other under the action of the No. 1 spring sheet, and the splint clamps the catheter when it moves to prevent the catheter from being pulled and then detached from the infusion bottle, which affects the normal infusion.

[0008] According to the above technical solution, the locking block contacts the notch, a No. 1 spring is provided between the splint and the limiting frame, a spring is provided between the slide and the limiting frame, and an arc-shaped spring is fixedly installed on the surface of the limiting frame, through which the catheter can be restricted inside the limiting frame.

[0009] According to the above technical solution, the circular plate is slidably installed on the surface of the support frame, and the adsorption device includes an arc block, a linkage rod, a sealing frame, a sealing plate, a connecting rod and a suction cup. A groove is opened on the surface of the support frame, and the arc block slides inside the groove.

The sealing plate is slidably installed inside the sealing frame. The bottom of the linkage rod is fixed to the sealing plate, and the connecting rod is fixedly installed on the bottom of the sealing plate. The suction cup is fixedly installed on the bottom of the connecting rod. When the linkage rod moves downward, it will drive the sealing plate to move downward. When the sealing plate moves downward, it will drive the connecting rod and the suction cup to move downward. When the suction cup moves downward, it will fit on the ground, so that the suction cup will be adsorbed on the ground, restricting the movement of the base.

[0010] According to the above technical solution, a No. 2 spring piece is provided between the arc block and the groove, a reset spring is provided between the circular plate and the support frame, and the suction cup is connected to the interior of the sealing frame through a hose. The No. 2 spring piece can drive the arc block to reset. At the same time, when the sealing plate moves downward, negative pressure will be formed on the top of the sealing plate, causing the top of the sealing plate to suck air from the inside of the suction cup through the hose, thereby increasing the effect of the suction cup adsorbing on the ground.

[0011] According to the above technical solution, it also includes a limiting device and a protective device, the protective device includes an elastic plate and a release component, the surface of the base is provided with a limiting device, the limiting device includes a rotating shaft, the rotating shaft is rotatably mounted on the top of the base, a spiral groove is provided on the surface of the rotating shaft, a contact rod is slidably mounted on the inner wall of the base, an extrusion rod is fixedly mounted on the surface of the rotating shaft, a hollow rubber is fixedly mounted on the top of the base, a support plate is fixedly mounted on the bottom of the connecting plate, a hook is slidably mounted on the surface of the support plate, an arc frame is fixedly mounted on the surface of the hook, and the bottom of the arc frame is slidably sleeved There is an arc-shaped rod, and a pressure plate is rotatably installed on the surface of the hook. The bottom of the arc-shaped rod is fixed to the pressure plate. The hollow rubber is connected to the interior of the arc frame through a pipe. When the rotating shaft rotates, it drives the extrusion rod to rotate. When the extrusion rod rotates, it squeezes the hollow rubber, so that the gas hot air pipe inside the hollow rubber enters the interior of the arc frame. When the air pressure inside the arc frame increases, it pushes the arc-shaped rod to move toward the outside of the arc frame, so that the arc-shaped rod pushes the pressure plate to move downward. The downward movement of the pressure plate will restrict the infusion bottle on the hook, preventing the infusion bottle from being removed from the hook at will, thereby improving the effect of hanging the infusion bottle on the hook. According to the above technical solution, the contact rod is in contact with the spiral groove, a spiral spring is arranged between the rotating shaft and the base, a piston is arranged between the arc rod and the inside of the arc frame, and a torsion spring is arranged between the pressure plate and the hook, so that when the air pressure inside the arc frame increases, the arc rod will move toward the outside of the arc frame.

When the rotating shaft rotates, the force rod and the pushing block will be driven to rotate. Under the action of centrifugal force, the pushing block will move in the direction of the trapezoidal block, so that the pushing block will push the trapezoidal block and the scraper downward, thereby preventing foreign objects on the ground from affecting the tightness of the suction cup adsorbed on the ground.

[0013] According to the above technical solution, the elastic plate is fixedly mounted on the surface of the hook, and the release assembly includes a transmission rod and a limit block. The transmission rod is fixedly mounted on the bottom of the elastic plate, and the limit block slides through the support plate. When the transmission rod moves downward, it pushes the limit block to move. The movement of the limit block releases the limit on the hook, so that the hook drives the infusion bottle downward under the action of gravity, making it convenient to remove the infusion bottle from the hook, while preventing the infusion bottle from being further pulled with great force.

[0014] According to the above technical solution, a slope is provided on the side of the transmission rod close to the limit block, and an elastic member is provided between the limit block and the support plate, so that the slope of the transmission rod can push the limit block to move when the transmission rod moves downward.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are: (1) The adjustment mechanism of the IV stand for emergency department nursing care, the restriction of the arc-shaped spring piece allows the catheter to move inside the restriction frame, so that the catheter will be between the rubber wheels. When the catheter rotates downward quickly, the elastic telescopic block will push the slide plate and the push rod upward under the action of centrifugal force. When the push rod moves upward, it will push the positioning block to release the restriction on the splint, so that the splint will clamp the catheter, preventing the catheter from being pulled and detached from the infusion bottle, which will affect the normal infusion.

[0016] (2) The adjustment mechanism of the IV stand for emergency department nursing pushes the circular plate downward to limit the circular plate through the arc block. At the same time, the circular plate drives the linkage rod and the suction cup to move downward, so that the suction cup is adsorbed on the ground, limiting the movement of the base and improving the stability of the base. When the sealing plate moves downward, the top of the sealing plate will generate negative pressure to suck air from the inside of the suction cup, thereby increasing the effect of the suction cup adsorbing on the ground.

[0017] (3) The adjustment mechanism of the infusion stand for emergency nursing care, when the circular plate moves downward, it will drive the contact rod to push the rotating shaft to rotate, so that the extrusion rod will squeeze the hollow rubber, so that the gas inside the hollow rubber enters the interior of the arc frame and pushes the arc rod and the pressure plate to rotate downward. The infusion bottle will be restricted on the hook through the pressure plate to prevent the infusion bottle from being removed from the hook at will, thereby improving the effect of the infusion bottle hanging on the hook. At the same time, when the rotating shaft rotates, the scraper will remove foreign matter on the ground to prevent foreign matter on the ground from affecting the tightness of the suction cup adsorbed on the ground.

[0018] (4) The adjustment mechanism of the infusion stand for emergency department nursing is such that when the infusion bottle is pulled downward with great force, the infusion bottle will squeeze the elastic plate to produce deformation, so that the elastic plate will drive the transmission rod to move downward, and the movement of the transmission rod will push the limit block to move to release the limit on the hook, so that the hook will drive the infusion bottle to move downward, thereby making it easier to remove the infusion bottle from the hook and preventing the infusion bottle from being further pulled with great force.

A hook 66 is slidably mounted on the surface of the supporting plate 65. An arc frame 67 is fixedly mounted on the surface of the hook 66. An arc rod 68 is slidably sleeved on the bottom of the arc frame 67. A pressure plate 69 is rotatably mounted on the surface of the hook 66. The bottom of the arc rod 68 is fixed to the pressure plate 69. The hollow rubber 64 is fixedly mounted on the top of the base 1. The circular plate 51 is connected to the interior of the arc frame 67 through a pipe. When the circular plate 51 moves downward, it contacts the contact rod 62. The downward movement of the circular plate 51 pushes the contact rod 62 downward. When the contact rod 62 moves downward inside the spiral groove, it drives the rotating shaft 61 to rotate. When the rotating shaft 61 rotates, it drives the extrusion rod 63 to rotate. When the extrusion rod 63 rotates, it squeezes the hollow rubber 64, so that the gas hot air pipe inside the hollow rubber 64 enters the interior of the arc frame 67. When the air pressure inside the arc frame 67 increases, it pushes the arc rod 68 to move toward the outside of the arc frame 67, so that the arc rod 68 pushes the pressure plate 69 downward. The downward movement of the pressure plate 69 restricts the infusion bottle on the hook 66, preventing the infusion bottle from being arbitrarily removed from the hook 66, thereby improving the effect of the infusion bottle hanging on the hook 66. The contact rod 62 is in contact with the spiral groove, a spiral spring is arranged between the rotating shaft 61 and the base 1, a piston is arranged between the arc rod 68 and the inside of the arc frame 67, and a torsion spring is arranged between the pressure plate 69 and the hook 66, so that when the air pressure inside the arc frame 67 increases, the arc rod 68 will also move toward the outside of the arc frame 67.

When the extrusion rod 63 rotates, it squeezes the hollow rubber 64, so that the gas hot air duct inside the hollow rubber 64 enters the interior of the arc frame 67. When the air pressure inside the arc frame 67 increases, it pushes the arc The arc-shaped rod 68 moves toward the outside of the arc-shaped frame 67, so that the arc-shaped rod 68 pushes the pressure plate 69 to move downward. The downward movement of the pressure plate 69 restricts the infusion bottle on the hook 66. At the same time, when the rotating shaft 61 rotates, the scraper 71 is driven to rotate. When the rotating shaft 61 rotates, the force-bearing rod 73 and the pushing block 74 are driven to rotate. Under the action of centrifugal force, the pushing block 74 moves toward the direction of the trapezoidal block 72, so that the pushing block 74 pushes the trapezoidal block 72 and the scraper 71 downward, so that the scraper 71 can remove foreign matter on the ground at the bottom of the suction cup 57. When the infusion bottle is pulled hard on the hook 66, the infusion bottle will press the elastic plate 81 to cause deformation. When the elastic plate 81 is deformed, it will drive the transmission rod 82 to move downward. When the transmission rod 82 moves downward, the inclined surface on the transmission rod 82 will push the limit block 83 to move.
