Description
Technical Field
[0001] The present invention relates to the technical field of infusion auxiliary equipment, in particular to an infusion stand for an intensive care unit. Background Art
[0002] The intensive care unit is used to monitor seriously ill patients. Most of the patients are in a state of severe coma and need to be given a large amount of drugs. Giving patients infusions and monitoring patients will result in a large number of pipelines and confusion, especially the infusion tubes mixed in. The infusion stand is a commonly used support stand for hanging infusion bottles. During infusion, if the reserved length of the infusion tube between the infusion stand and the patient is long, it is easy to get entangled with other pipelines, causing pipeline confusion and interfering with each other during use. If the infusion tube is tightened and the reserved length of the infusion tube between the infusion stand and the patient is shortened, the tape used to fix the needle may be torn off during patient activities or medical staff operations, and it is also easy to pull the needle on the infusion tube, causing the needle to detach. In addition, the infusion tube being pulled can easily cause the infusion bottle to shake violently, and there is a risk of the infusion bottle falling. Summary of the Invention
[0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide an infusion stand for an intensive care unit. During infusion, the infusion tube can be combed out, so that the reserved length of the infusion tube between the infusion stand and the patient is shortened, thereby avoiding entanglement with other pipelines to cause confusion during use and avoiding interference with other pipelines. When the infusion tube is pulled, the combed infusion tube can be released to avoid the tape being torn open and the needle being detached from the patient. Moreover, when the infusion tube is pulled, the infusion bottle hanging on the infusion stand is not easy to shake, thereby avoiding the infusion bottle falling from the infusion stand, which can effectively solve the problems in the background technology.
[0004] To achieve the above-mentioned object, the present invention provides the following technical solution: an IV stand for an intensive care unit, comprising an IV support rod and: The infusion tube combing mechanism includes a tube-winding arc plate, an adjustment sleeve 1 is sleeved on the middle part of the infusion support rod, one side of the adjustment sleeve is fixedly connected to one end of the crossbeam, a sliding sleeve is slidably connected to the crossbeam, the bottom of the sliding sleeve is fixedly connected to the top of the core column, and three groups of radial telescopic rods are arranged in a circular array on the outer peripheral side of the bottom of the core column, and the end of each group of radial telescopic rods away from the core column is respectively fixedly connected to the inner side of the tube-winding arc plate, and a stretching compression spring is sleeved on the radial telescopic rod, a rubber stopper is installed on the side of the infusion support rod close to the crossbeam, and the rubber stopper is arranged horizontally corresponding to the bottom side surface of the tube-winding arc plate, the core column is connected to the crossbeam through a core column transverse movement limit assembly, and the core column transverse movement limit assembly is connected to the tube-winding arc plate expansion and contraction control assembly; The anti-sway mechanism for the infusion bottle is installed on the top of the infusion support rod; The infusion bottle hanging anti-falling mechanism is installed on the infusion bottle anti-swaying mechanism.
[0005] Furthermore, the core column transverse movement limit assembly includes a transverse guide groove. The transverse guide groove is formed on the front side of the crossbeam, and an inverted V-shaped groove is formed on the upper side of the end of the transverse guide groove near the adjustment sleeve. A sliding ring is vertically slidably sleeved on the top of the core column. A convex ring is fixedly connected to the outer side of the core column below the sliding ring. The column section of the core column located between the convex ring and the sliding ring is sleeved with a limit compression spring. The sliding ring is fixedly connected to the bottom end of the vertical rod, and the top end of the vertical rod is rotatably connected to the guide column. The guide column is in rolling connection with the upper side of the transverse guide groove. When the guide column is located at the top of the inverted V-shaped groove, the end of the rubber stopper abuts the outer side of the bottom of the corresponding pipe-wound circular arc plate.
[0006] When the sliding sleeve slides left and right along the cross beam, it can also drive the vertical rod and the guide column to move left and right. At this time, the guide column will also move left and right along the cross guide groove. When the sliding sleeve moves along the cross beam in the direction away from the infusion support rod, the guide column moves along the cross guide groove in the direction away from the infusion support rod. At this time, the height of the sliding ring remains unchanged. When the sliding sleeve moves along the cross beam in the direction close to the infusion support rod, the guide column gradually enters the inverted V-shaped groove. At this time, the limit compression spring extends, pushing the sliding ring to slide upward along the core column, pushing the guide column to the top of the inverted V-shaped groove. At this time, not only the end of the rubber stopper presses against the outer side of the bottom of the corresponding pipe winding arc plate, but also due to the elastic force of the limit compression spring, the guide column is stably at the top of the inverted V-shaped groove, and the sliding sleeve is no longer easy to slide left and right along the cross beam, and can also maintain the pipe winding. The cylindrical structure is in a relatively stable state, thereby limiting the left and right positions of the core column. At this time, since the end of the rubber stopper is against the outer side of the bottom of the corresponding tube-winding arc plate, it is not easy to spirally wind the infusion tube on the tube-winding cylindrical structure. When it is necessary to spirally wind the infusion tube on the tube-winding cylindrical structure, pull the sliding sleeve hard to move the sliding sleeve and the core column away from the infusion support rod. At this time, the guide column moves away from the infusion support rod along the inverted V-shaped groove, and the inclined surface of the inverted V-shaped groove guides the guide column to move downward, overcoming the elastic force of the limit compression spring. The limit compression spring is compressed, allowing the sliding ring to slide downward along the core column, and then the guide column enters the transverse guide groove, and then the sliding sleeve and the core column continue to move away from the infusion support rod, and the tube-winding cylindrical structure also moves away from the infusion support rod, and the infusion tube can be spirally wound on the tube-winding cylindrical structure.
[0007] Furthermore, the expansion and contraction control assembly of the pipe-wrap circular arc plate includes a control ring, and an inclined groove is provided in the center of the top outer side of each pipe-wrap circular arc plate. The inner annular array of the control ring is provided with three guide protrusions, and each guide protrusion is in friction contact with the inner side of the inclined groove. The top of the control ring is fixedly connected to the two sides of the sliding ring through two bent frames. When the guide post is in the transverse guide groove, the sliding ring slides downward along the core post, driving the control ring and the guide protrusion to move downward through the two bent frames. The control ring contacts the inner side of the inclined groove through the guide protrusion, pushing the three pipe-winding arc plates together. At this time, the radial telescopic rod is shortened, and the expansion compression spring on the radial telescopic rod is compressed. The outer circumference of the pipe-winding cylindrical structure composed of the three pipe-winding arc plates is shortened. At this time, the infusion tube is spirally wound around the outer side of the pipe-winding cylindrical structure. When winding the infusion tube, it is not necessary to wind it tightly. It is only necessary to wind the infusion tube quickly and loosely. Then, when the sliding sleeve moves along the cross beam toward the infusion support rod, the guide post gradually enters the inverted V-shaped groove. At this time, the limit compression spring extends, pushing the sliding ring to slide upward along the core post, pushing the guide post to be in the inverted V-shaped groove. At the inner top, the sliding ring drives the control ring and the guide protrusion to move upward through the two bent frames, the squeezing effect of the guide protrusion on the inner side of the inclined groove is reduced, the radial telescopic rod is reset and extended, the radial telescopic rod is extended, and the three tube-winding arc plates move away from each other. The outer circumference of the tube-winding cylindrical structure composed of the three tube-winding arc plates increases, and the loosely wound infusion tube can also be tightened. The setting of the tube-winding arc plate expansion and contraction control component does not require the user to spend too much time on winding the infusion tube, only loose winding is required, and when the tube-winding cylindrical structure is close to the infusion support rod, the outer circumference of the tube-winding cylindrical structure increases, and the infusion tube can be tightened. Since the two ends of the spirally wound infusion tube are not fixed, the infusion tube wound on the tube-winding cylindrical structure will not be flattened, and will not affect the infusion.
[0008] Furthermore, the infusion tube combing mechanism also includes a combing horizontal cylinder, the adjustment sleeve is fixedly connected to the top of the top plate on the side away from the cross beam, the bottom of the top plate is connected to the bottom plate through a distance adjustment component, the top plate is fixedly connected to a fixed column on the side away from the infusion support rod, the outer side of the fixed column is rotatably sleeved with a combing horizontal cylinder, two retaining rings are respectively provided at both ends of the combing horizontal cylinder, and a folding winding component is installed on the side of the bottom plate away from the infusion support rod. The distance-adjusting assembly is used to change the distance between the top plate and the bottom plate. When the distance between the top plate and the bottom plate becomes larger, the length of the infusion tube wrapped around the combing horizontal cylinder and the folding winding assembly will increase. When the distance between the top plate and the bottom plate decreases, the length of the infusion tube wrapped around the combing horizontal cylinder and the folding winding assembly will decrease. The combing horizontal cylinder can rotate relative to the fixed column, and the infusion tube and the combing horizontal cylinder are in rolling contact, reducing the friction when the infusion tube contacts the combing horizontal cylinder. The retaining ring limits the outer peripheral sides of both ends of the combing horizontal cylinder to prevent the infusion tube from detaching from the end of the combing horizontal cylinder. The infusion tube is wound between the combing horizontal cylinder and the folding winding assembly. When the bottom of the infusion tube is pulled, the folding winding assembly folds upward, so that the infusion tube wrapped between the combing horizontal cylinder and the folding winding assembly can be released. If the pulling length is too large, the infusion tube will detach from the end of the folding winding assembly, releasing a longer infusion tube.
[0009] Furthermore, the folding winding assembly includes a combing slide, a round seat is provided on the side of the base plate away from the infusion support rod, the round seat is movably connected to one end of the folding column through a movable shaft, the outer side of the folding column is slidably sleeved with a combing slide, and the combing slide is connected to the folding column through an anti-detachment assembly. When it is necessary to wind the infusion tube between the combing horizontal cylinder and the combing slide cylinder, the combing slide cylinder is slid relative to the folding column, and the end of the combing slide cylinder is sleeved on the round seat. At this time, the folding column can no longer move relative to the round seat through the movable shaft, and the infusion tube can be quickly and stably wound between the combing horizontal cylinder and the combing slide cylinder. Due to the gravity of the infusion tube, the infusion tube is easily squeezed and deformed when it contacts the top of the combing horizontal cylinder, which will affect the infusion efficiency of the infusion tube to a certain extent. By shortening the distance between the combing horizontal cylinder and the combing slide cylinder with the help of the distance adjustment component, this problem can be solved to a certain extent. After the infusion tube is wound between the combing horizontal cylinder and the combing slide cylinder, the combing slide cylinder is slid relative to the folding column, allowing the round seat and the movable shaft to leak out. If the bottom of the infusion tube is pulled, the combing slide cylinder and the folding column move relative to the round seat through the movable shaft, and the end of the combing slide cylinder and the folding column away from the round seat is folded upward, so that a part of the infusion tube wound between the combing horizontal cylinder and the combing slide cylinder can be released. If the infusion tube continues to be pulled, the infusion tube wound on the right end of the combing slide cylinder will break away from the combing slide cylinder, releasing a longer infusion tube.
[0010] Furthermore, the infusion bottle anti-sway mechanism includes a mounting box and an anti-sway limit assembly, the top of the infusion support rod is fixedly connected to the mounting box, and the two sides of the mounting box are fixedly connected to two transmission boxes through two connecting sleeves, each transmission box is fixedly connected to a fixing sleeve on the side away from the mounting box, and a control slide rod is slidably connected in each fixing sleeve, and each control slide rod is fixedly connected to an end rod at one end away from the mounting box, and the end of the end rod close to the fixing sleeve is fixedly connected to a magnetic block, and the end of the fixing sleeve is fixedly connected to an iron block at one end away from the mounting box, and an anti-sway limit assembly is installed on each transmission box.
[0011] Furthermore, the anti-sway limit assembly includes an arc-shaped anti-sway limit frame, and the front and rear sides of the bottom of each transmission box are rotatably connected to the top ends of two rotating shafts, and the top ends of the two rotating shafts are fixedly connected to two gears. The end of the control slide rod close to the transmission box is fixedly connected to a double-sided rack, and the front and rear sides of the double-sided rack are respectively meshed with the two gears, and the bottom ends of the two rotating shafts are respectively fixedly connected to the ends of the two arc-shaped anti-sway limit frames.
[0012] Furthermore, the infusion bottle hanging and anti-drop mechanism includes a rectangular frame, a rectangular frame is installed at the bottom of each end rod, a hanging frame is vertically slidably connected inside the rectangular frame, the top of the hanging frame is connected to the bottom of the spring connecting frame via a vertical anti-drop tension spring, the top of the spring connecting frame is installed at the top of the rectangular frame, a camera is installed at the end of the end rod, and a hanging notch is formed in the middle of the hanging frame and the side of the rectangular frame away from the installation box. When the infusion bottle is not hung on the hanging frame, the hanging notch on the hanging frame is arranged horizontally corresponding to the hanging notch on the rectangular frame, and the hanging frame is then located in the middle of the rectangular frame.
[0013] When the bottle is lifted up, the anti-slip spring is reset and shortened, driving the hanging frame to move up relative to the rectangular frame, and the hanging notch on the hanging frame is horizontally set to the hanging notch on the rectangular frame. At this time, the hanging ring can be taken out from the hanging notch of the hanging frame, and the infusion bottle can be taken out. The camera can remotely monitor the amount of liquid medicine in the infusion bottle, which needs to be used in conjunction with remote communication equipment and monitoring terminals.
[0014] Furthermore, it also includes an infusion tube elastic clamping mechanism, the infusion tube elastic clamping mechanism includes a fan-shaped clamping block, the bottom of the infusion support rod is sleeved with an adjustment sleeve 2, the adjustment sleeve 2 is fixedly connected to the infusion support rod by a butterfly bolt 2, and the two sides of the adjustment sleeve are respectively fixedly connected to two longitudinal support plates, the rear side of each support plate is respectively fixedly connected to a clamping plate, the middle part of the clamping plate is provided with a circular arc structure protruding backward, the support plate is movably connected to the top of the fan-shaped clamping block through a horizontal positioning movable column, the circular arc surface on the rear side of the fan-shaped clamping block corresponds to the middle front side of the clamping plate, and the middle part of the circular arc surface of the fan-shaped clamping block and the middle part of the front side of the clamping plate are both provided with arc grooves, and the front end of the fan-shaped clamping block is connected to the clamping elastic control component. The clamping elastic control component elastically pushes the front end of the fan-shaped clamping block upward, allowing the fan-shaped clamping block to move relative to the positioning movable column, so that the arc surface of the fan-shaped clamping block is close to the arc structure part in the middle of the clamping plate. The infusion tube passes between the clamping plate and the arc surface of the fan-shaped clamping block. The specific relative structure can be seen Figure 3 Due to the arc grooves in the middle of the arc surface of the fan-shaped clamping block and the middle of the front side of the clamping plate, the arc surface of the clamping plate and the fan-shaped clamping block can prevent the infusion tube from being clamped flat and affecting the infusion. If the bottom end of the infusion tube is pulled, the front end of the fan-shaped clamping block overcomes the elastic force of the clamping elastic control component, and the rear side of the fan-shaped clamping block moves downward. The fan-shaped clamping block gradually leaves the clamping plate and loses the clamping effect on the infusion tube. The infusion tube moves downward relative to the clamping plate, which can release a longer infusion tube and shorten the reserved length of the infusion tube between the infusion stand and the patient, avoiding entanglement with other pipelines and causing confusion during use. When the infusion tube is pulled, the combed infusion tube can be released to avoid tearing the tape and causing the needle to fall off the patient.
[0015] Furthermore, the clamping elastic control component includes a slide, the front side of the support plate is movably connected to the slide through a short shaft, a sliding control column is inserted into the through hole on the slide, the rear end of the sliding control column is movably connected to the front end of the fan-shaped clamping block through a pin shaft, a button is installed at the front end of the sliding control column, and the column section of the sliding control column located between the button and the slide is sleeved with a clamping compression spring. When the infusion tube needs to be manually released, the button is pressed upward, the clamping compression spring is compressed, and the front end of the fan-shaped clamping block is pushed upward with the help of the sliding control column, so that the rear side of the fan-shaped clamping block can move downward, and the fan-shaped clamping block gradually leaves the clamping plate, losing its clamping effect on the infusion tube.
[0016] Compared with the existing technology, the beneficial effects of this infusion stand for intensive care unit are: 1. The three arc-shaped tube-winding plates form a tube-winding cylindrical structure that can be spirally wound around the infusion tube. The setting of the expanded compression spring allows a certain elastic buffer space between the tube-winding arc-shaped plate and the core column, which is conducive to more stable spiral winding of the infusion tube around the outer side of the tube-winding cylindrical structure.
[0017] 2. When it is necessary to spirally wind the infusion tube around the outer side of the tube-wrap cylindrical structure, first move the sliding sleeve along the crossbeam away from the infusion support rod, so that the tube-wrap cylindrical structure is away from the infusion support rod, and the rubber stopper is also away from the bottom side of the corresponding tube-wrap circular arc plate. At this time, the infusion tube can be spirally wound around the outer side of the tube-wrap cylindrical structure. After winding, let the sliding sleeve move along the crossbeam close to the infusion support rod, and let the rubber stopper press against the bottom side of the corresponding tube-wrap circular arc plate. Due to the setting of the rubber stopper, the spiral winding around the outer side of the tube-wrap cylindrical structure can be blocked. The bottom of the wrapped infusion tube can be combed out. Since the infusion tube is stably spirally wound on the tube-winding cylindrical structure, there is no bending in the infusion tube, which will not interfere with the infusion of the infusion tube. If the infusion tube is pulled during infusion, the infusion tube will deform the rubber stopper close to the end of the tube-winding arc plate, and the infusion tube will pass through the gap between the deformed end of the rubber stopper and the tube-winding arc plate. The infusion tube will be released from the bottom outside of the tube-winding cylindrical structure for a circle, so as to prevent the needle at the bottom end of the infusion tube from being separated from the patient's body when the infusion tube is pulled.
[0018] 3. During infusion, the infusion tube can be combed to shorten the reserved length of the infusion tube between the infusion stand and the patient, avoid entanglement with other pipelines and cause confusion during use, and avoid interference with other pipelines. When the infusion tube is pulled, the combed infusion tube can be released to avoid tearing the tape and causing the needle to detach from the patient.
[0019] 4. Align the hanging ring on the infusion bottle with the hanging notches on the hanging frame and the rectangular frame, and hang the hanging ring on the hanging frame. Due to the gravity of the infusion bottle, the anti-detachment stretching spring is stretched, and the hanging frame slides downward along the rectangular frame until the hanging frame is at the bottom of the rectangular frame. At this time, the hanging notch on the hanging frame is staggered with the hanging notch on the rectangular frame. Even if the infusion bottle shakes greatly, the hanging ring on the infusion bottle is not easy to detach from the hanging frame, which can avoid the infusion bottle from falling due to large shaking. When the infusion bottle needs to be removed, hold the infusion bottle and move it up. The anti-detachment stretching spring resets and shortens, driving the hanging frame to move up relative to the rectangular frame. The hanging notch on the hanging frame is set horizontally corresponding to the hanging notch on the rectangular frame. At this time, the hanging ring can be removed from the hanging notch of the hanging frame, and the infusion bottle can be removed.
[0020] When the locking cam is in the closed position, the locking cam is in the closed position, and the locking cam is in the closed position, so that the locking cam is in the closed position and the locking cam is in the closed position, so that the locking cam is in the closed position and the locking cam is in the closed position, and the locking cam is in the closed position, so that the locking cam is in the closed position and the locking cam is in the closed position, and the locking cam is in the closed position, so that the locking cam is in the closed position and the locking cam is in the closed position, and the locking cam is in the closed position, so that the locking cam is in the closed position and the locking cam is in the closed position,
[0021] Furthermore, when the infusion tube is pulled, the infusion bottle hanging on the infusion stand is not easily shaken, thereby preventing the infusion bottle from falling from the infusion stand. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] For example 1, please refer to Figures 1 to 8 This embodiment provides a technical solution: an infusion stand for an intensive care unit, comprising an infusion support rod 1, the bottom of which can be connected to a movable base or fixedly installed at the head of a bed, and further comprising an infusion bottle anti-sway mechanism 2, an infusion bottle hanging anti-fall mechanism 3 and an infusion tube combing mechanism 4.
[0025] The anti-sway mechanism 2 of the infusion bottle includes a mounting box 21, a connecting sleeve 22, a transmission box 23, a fixing sleeve 24, a control slide rod 25, an end rod 27, an iron block 28, a magnetic block 29 and an anti-sway limit assembly. The top of the infusion support rod 1 is fixedly connected to the mounting box 21, and the two sides of the mounting box 21 are fixedly connected to two transmission boxes 23 through two connecting sleeves 22. Each transmission box 23 is fixedly connected to a fixing sleeve 24 on the side away from the mounting box 21, and a control slide rod 25 is slidably connected in each fixing sleeve 24. The end of each control slide rod 25 away from the mounting box 21 is fixedly connected to the end rod 27, and the end of the end rod 27 close to the fixing sleeve 24 is fixedly connected to the magnetic block 29. The end of the fixing sleeve 24 away from the mounting box 21 is fixedly connected to the iron block 28. The iron block 28 and the magnetic block 29 are arranged correspondingly on the left and right, and an anti-sway limit assembly is installed on each transmission box 23.
[0026] The infusion bottle anti-sway mechanism 2 also includes an anti-slip column 26. An anti-slip transverse groove is provided on the top of the fixed sleeve 24. The top of the control slide rod 25 is threadedly connected to the position corresponding to the anti-slip transverse groove. The anti-slip column 26 can only move left and right in the anti-slip transverse groove, thereby limiting the lateral movement range of the control slide rod 25 and the end rod 27, and preventing the control slide rod 25 from detaching from the fixed sleeve 24.
[0027] When the anti-slip column 26 is in the anti-slip transverse groove close to one end of the infusion support rod 1 , the iron block 28 and the magnetic block 29 are magnetically attracted together.
[0028] The anti-sway limit assembly includes a rotating shaft 210, a gear 211, a double-sided rack 212 and an arc-shaped anti-sway limit frame 213. The front and rear sides of the bottom of each transmission box 23 are respectively rotatably connected to the top of the two rotating shafts 210 through bearings. The tops of the two rotating shafts 210 are respectively fixedly connected to the two gears 211. The control slide bar 25 is fixedly connected to the double-sided rack 212 at one end close to the transmission box 23. The double-sided rack 212 is located between the two gears 211. The front and rear sides of the double-sided rack 212 are respectively meshed with the two gears 211. The bottom ends of the two rotating shafts 210 are respectively fixedly connected to the ends of the two arc-shaped anti-sway limit frames 213. The two arc-shaped anti-sway limit frames 213 are arranged relative to each other front and back.
[0029] When the control slide bar 25 is away from the installation box 21 and the infusion support rod 1, the control slide bar 25 drives the double-sided rack 212 to move away from the installation box 21, and the meshing action of the double-sided rack 212 and the two gears 211 drives the two rotating shafts 210 to rotate in opposite directions, wherein the front rotating shaft 210 rotates clockwise and the rear rotating shaft 210 rotates counterclockwise, and the two rotating shafts 210 drive the two arc anti-sway limit frames 213 to open. At this time, the infusion bottle hanging anti-slip mechanism 3 also moves away from the installation box 21 with the end rod 27, and the infusion bottle 7 hung on the infusion bottle hanging anti-slip mechanism 3 also moves away from the installation box 21 and the infusion support rod 1, which is convenient for replacing a new infusion bottle 7 on the infusion bottle hanging anti-slip mechanism 3. When the control slide bar 25 is close to the installation box 21 and the infusion support rod 1, the control slide bar 25 drives the double-sided rack 212 to move towards the installation box 21, and the meshing action of the double-sided rack 212 and the two gears 211 drives The two arc-shaped anti-sway limit frames 213 gradually approaching each other, and the front and rear sides of the infusion bottle 7 are limited to the front and rear sides of the infusion bottle 7, reducing the shaking of the infusion bottle 7 during movement, preventing the shaking infusion bottle 7 from separating from the infusion tube 6, and also reducing the risk of the hanging ring 8 on the infusion bottle 7 separating from the infusion bottle hanging anti-sway mechanism 3. At this time, the magnetic block 29 and the iron block 28 magnetically maintain the relative position of the control slide bar 25 and the fixing sleeve 24 stable, thereby maintaining the relative position of the two arc-shaped anti-sway limit frames 213 and the infusion bottle 7 stable.
[0030] The infusion bottle hanging anti-falling mechanism 3 is installed at the bottom of the end rod 27.
[0031] The infusion bottle hanging anti-slip mechanism 3 includes a rectangular frame 31, a spring connecting frame 32, an anti-slip tension spring 33, a hanging frame 34 and a camera 35. The bottom of each end rod 27 is respectively installed with a rectangular frame 31 by a bolt, and the hanging frame 34 is vertically slidably connected in the rectangular frame 31. The top of the hanging frame 34 is connected to the bottom of the spring connecting frame 32 through a vertical anti-slip tension spring 33. The top of the spring connecting frame 32 is installed in the top of the rectangular frame 31. The end of the end rod 27 is installed with a camera 35. The hanging frame 34 and the rectangular frame 31 are both provided with a hanging notch in the middle of the side away from the mounting box 21. When the infusion bottle 7 is not hung on the hanging frame 34, the hanging notch on the hanging frame 34 is horizontally corresponding to the hanging notch on the rectangular frame 31. At this time, the hanging frame 34 is in the middle of the rectangular frame 31.
[0032] The hanging ring 8 on the infusion bottle 7 is aligned with the hanging notch on the hanging frame 34 and the rectangular frame 31, and the hanging ring 8 is hung on the hanging frame 34. Due to the gravity of the infusion bottle 7, the anti-dropping tension spring 33 is stretched, and the hanging frame 34 slides downward along the rectangular frame 31 until the hanging frame 34 is located at the bottom of the rectangular frame 31. At this time, the hanging notch on the hanging frame 34 is staggered with the hanging notch on the rectangular frame 31. Even if the infusion bottle 7 shakes greatly, the hanging ring 8 on the infusion bottle 7 is not easy to detach from the hanging frame 34, which can prevent the infusion bottle 7 from falling due to the large shaking. , hold the infusion bottle 7 and move it upward, the anti-slip tension spring 33 is reset and shortened, driving the hanging frame 34 to move upward relative to the rectangular frame 31, and the hanging notch on the hanging frame 34 is set horizontally corresponding to the hanging notch on the rectangular frame 31. At this time, the hanging ring 8 can be taken out from the hanging notch of the hanging frame 34, and the infusion bottle 7 can be removed. The camera 35 can remotely monitor the amount of liquid medicine in the infusion bottle 7, which needs to be used in conjunction with remote communication equipment and monitoring terminals. The components that power the camera 35 and the remote communication equipment can be installed in the installation box 21, and its specific electrical connection method adopts the existing technology.
[0033] The infusion tube combing mechanism 4 is installed in the middle of the infusion support rod 1 .
[0034] The infusion tube combing mechanism 4 includes an adjustment sleeve 41, a butterfly bolt 42, a crossbeam 43, a sliding sleeve 44, a radial telescopic rod 45, a stretching compression spring 46, a tube-wrap circular arc plate 47, a rubber stopper 434, a core column 435, a core column transverse movement limit assembly and a tube-wrap circular arc plate expansion and retraction control assembly. The middle part of the infusion support rod 1 is sleeved with an adjustment sleeve 41, and the adjustment sleeve 41 is fixedly connected to the infusion support rod 1 through a butterfly bolt 42. One side of the adjustment sleeve 41 is fixedly connected to one end of the crossbeam 43. A sliding sleeve 44 is laterally slidably connected to the crossbeam 43, and the bottom of the sliding sleeve 44 is fixedly connected to the core column. The top of 435 and the bottom outer peripheral side of the core column 435 are provided with three groups of radial telescopic rods 45 in a circular array, and the end of each group of radial telescopic rods 45 away from the core column 435 is fixedly connected to the inner side of the pipe-winding arc plate 47, and a stretching compression spring 46 is sleeved on the radial telescopic rod 45, and a rubber stopper 434 is installed on the side of the infusion support rod 1 close to the crossbeam 43, and the rubber stopper 434 is arranged horizontally corresponding to the bottom side surface of the pipe-winding arc plate 47, and the core column 435 is connected to the crossbeam 43 through the core column transverse movement limit assembly, and the core column transverse movement limit assembly is connected to the pipe-winding arc plate expansion and contraction control assembly.
[0035] By loosening the butterfly bolt 42, the adjustment sleeve 41 can be moved up and down along the infusion support rod 1, thereby adjusting the height of the adjustment sleeve 41. Then, the butterfly bolt 42 is tightened, and the butterfly bolt 42 is pressed against the infusion support rod 1 again to fix the adjustment sleeve 41 to the infusion support rod 1. Each set of radial telescopic rods 45 includes two radial telescopic rods 45, each of which is distributed along the radial direction of the core column 435. The three pipe-winding arc plates 47 form a pipe-winding cylindrical structure that can be spirally wound around the infusion tube 6. The setting of the expanded compression spring 46 allows the distance between the pipe-winding arc plate 47 and the core column 435 to have a certain elastic buffer space, which is conducive to more stable spiral winding of the infusion tube 6 on the outside of the pipe-winding cylindrical structure. When the infusion tube 6 is spirally wound around the outside of the pipe-winding cylindrical structure, the sliding sleeve 44 is first moved along the cross beam 43 away from the infusion support rod 1, so that the pipe-winding cylindrical structure is away from the infusion support rod 1, and the rubber stopper 434 is also aligned with the corresponding pipe-winding arc plate. The bottom side of the arc plate 47 is away from the bottom, and the infusion tube 6 can be spirally wound around the outer side of the tube-winding cylindrical structure. After winding, the sliding sleeve 44 is allowed to move along the crossbeam 43 close to the infusion support rod 1, and the rubber stopper 434 is allowed to abut the bottom side of the corresponding tube-winding circular arc plate 47. Due to the setting of the rubber stopper 434, the bottom of the infusion tube 6 spirally wound around the outer side of the tube-winding cylindrical structure can be blocked, so that the infusion tube 6 can be combed. Since the infusion tube 6 is stably spirally wound around the tube, the infusion tube 6 can be easily wound. On the tubular structure, the infusion tube 6 does not bend and will not interfere with the infusion of the infusion tube 6. If the infusion tube 6 is pulled during infusion, the infusion tube 6 causes the rubber stopper 434 to deform near one end of the tube-wrap circular arc plate 47, and the infusion tube 6 passes through the gap between the deformed end of the rubber stopper 434 and the tube-wrap circular arc plate 47. The infusion tube 6 is released from the bottom outer side of the tube-wrap cylindrical structure for a circle, thereby preventing the needle at the bottom end of the infusion tube 6 from being separated from the patient's body when the infusion tube 6 is pulled.
[0036] The core column transverse movement limit assembly includes a transverse guide groove 49, a sliding ring 410, a convex ring 414, a limit compression spring 415, a vertical rod 416 and a guide column 417. A transverse guide groove 49 is provided on the front side of the crossbeam 43, and an inverted V-shaped groove is provided on the upper side of the end of the transverse guide groove 49 close to the adjustment sleeve 41. The top of the core column 435 is vertically slidably sleeved with the sliding ring 410, and the outer side of the core column 435 is fixedly connected with the convex ring 414 at a position below the sliding ring 410. The column section of the core column 435 located between the convex ring 414 and the sliding ring 410 is sleeved with the limit compression spring 415. The bottom end of the vertical rod 416 is fixedly connected to the sliding ring 410, and the top of the vertical rod 416 is rotatably connected with the guide column 417. The guide column 417 is rollingly connected to the upper side of the transverse guide groove 49. When the guide column 417 is located at the top of the inverted V-shaped groove, the end of the rubber stopper 434 abuts against the outer side of the bottom of the corresponding pipe-wound circular arc plate 47.
[0037] When the sliding sleeve 44 slides left and right along the cross beam 43, it can also drive the vertical rod 416 and the guide post 417 to move left and right. At this time, the guide post 417 will also move left and right along the cross guide groove 49. When the sliding sleeve 44 moves along the cross beam 43 in the direction away from the infusion support rod 1, the guide post 417 moves along the cross guide groove 49 in the direction away from the infusion support rod 1. At this time, the height of the sliding ring 410 remains unchanged. When the sliding sleeve 44 moves along the cross beam 43 in the direction close to the infusion support rod 1, the guide post 417 gradually enters the inverted V-shaped groove. At this time, the limit compression spring 415 extends, pushing the sliding ring 410 to slide upward along the core column 435, pushing the guide post 417 to the top of the inverted V-shaped groove. At this time, not only the end of the rubber stopper 434 abuts against the outer side of the bottom of the corresponding winding pipe arc plate 47, but also due to the elastic force of the limit compression spring 415, the guide post 417 is stably at the top of the inverted V-shaped groove, and the sliding sleeve 44 is no longer easy to slide left and right along the cross beam 43 The guide post 417 is compressed and the sliding ring 410 slides downward along the core column 435, and then the guide post 417 enters the transverse guide groove 49, and then the sliding sleeve 44 and the core column 435 continue to move away from the infusion support rod 1, and the tube-wound cylindrical structure is also away from the infusion support rod 1, and the infusion tube 6 can be spirally wound on the tube-wound cylindrical structure.
[0038] The expansion and contraction control assembly of the pipe-wrap circular arc plate includes an inclined groove 48, a bent frame 411, a control ring 412 and a guide protrusion 413. An inclined groove 48 is provided in the center of the top outer side of each pipe-wrap circular arc plate 47. The top depth of the inclined groove 48 is greater than the bottom depth. Three guide protrusions 413 are provided in an inner annular array of the control ring 412. Each guide protrusion 413 is in friction contact with the inner side of the inclined groove 48. The top of the control ring 412 is fixedly connected to the two sides of the sliding ring 410 through two bent frames 411. When the guide post 417 is located in the transverse guide groove 49, the sliding ring 410 slides downward along the core post 435, and drives the control ring 412 and the guide protrusion 413 to move downward through the two bent frames 411. The control ring 412 contacts the inner side of the inclined groove 48 through the guide protrusion 413, pushing the three pipe-winding arc plates 47 together. At this time, the radial telescopic rod 45 is shortened, and the expansion compression spring 46 on the radial telescopic rod 45 is compressed. The outer circumference of the pipe-winding cylindrical structure composed of the three pipe-winding arc plates 47 is shortened. At this time, the infusion tube 6 is spirally wrapped around the outer side of the pipe-winding cylindrical structure. When winding the infusion tube 6, it is not necessary to wrap it tightly. It is only necessary to wrap the infusion tube 6 quickly and loosely. Then, when the sliding sleeve 44 moves along the cross beam 43 toward the direction close to the infusion support rod 1, the guide post 417 gradually enters the inverted V-shaped groove. At this time, the limit compression spring 415 extends, pushing the sliding ring 410 to slide upward along the core post 435 The guide post 417 is moved to the top of the inverted V-shaped groove. At this time, the sliding ring 410 drives the control ring 412 and the guide protrusion 413 to move upward through the two bent frames 411. The squeezing effect of the guide protrusion 413 on the inner side of the inclined groove 48 is reduced, and the radial telescopic rod 45 is reset and extended. The radial telescopic rod 45 is extended, and the three pipe-winding arc plates 47 are separated from each other. The outer circumference of the pipe-winding cylindrical structure formed by the three pipe-winding arc plates 47 is increased, and the loosely wound infusion tube 6 can also be tightened. The setting of the pipe-winding arc plate expansion and contraction control component does not require the user to spend too much time on winding the infusion tube 6, and only needs to be wound loosely. When the pipe-winding cylindrical structure is close to the infusion support rod 1, the outer circumference of the pipe-winding cylindrical structure is increased, and the infusion tube 6 can be tightened. Since the two ends of the spirally wound infusion tube 6 are not fixed, the infusion tube 6 wound on the pipe-winding cylindrical structure will not be flattened, and the infusion will not be affected.
[0039] When the infusion bottle 7 is in use, the infusion bottle support rod 1 plays a supporting role, and the infusion bottle anti-sway mechanism 2 and the infusion bottle hanging anti-slip mechanism 3 are lifted up, and the infusion bottle hanging anti-slip mechanism 3 is hung up by the hanging ring 8 on the infusion bottle 7. Among them, the transmission box 23 is used to install the anti-sway limit assembly, and the anti-sway limit assembly is used to limit the infusion bottle 7 to prevent the infusion bottle hung on the infusion stand from shaking when the infusion tube is pulled, and also to prevent the suspended infusion bottle from shaking greatly when the infusion support rod is transferred. When the infusion bottle 7 is hung on the infusion bottle hanging anti-slip mechanism 3, it is necessary to pull the end rod 27 first, and the pulling force overcomes the magnetic attraction of the magnetic block 29 and the iron block 28, so that the end rod 27 moves in the direction away from the installation box 21. At this time, the control slide bar 25 slides along the fixed sleeve 24 in the direction away from the installation box 21, and the control slide bar 25 drives the anti-sway limit assembly to open, and then The infusion bottle 7 is hung on the anti-slip mechanism 3, and then the end rod 27 is pushed to make the end rod 27 close to the installation box 21, and the control slide bar 25 slides along the fixing sleeve 24 toward the installation box 21. At this time, the control slide bar 25 drives the anti-sway limit assembly to close, and the anti-sway limit assembly limits the front and rear sides of the infusion bottle 7. At this time, the magnetic block 29 and the iron block 28 are magnetically attracted together, and the control slide bar 25 can no longer move away from the installation box 21 along the fixing sleeve 24, just making the anti-sway limit assembly close stably to limit the front and rear sides of the infusion bottle 7. The bottle mouth of the infusion bottle 7 is connected to the top of the infusion tube 6, and then the middle part of the infusion tube 6 is wrapped around the infusion tube combing mechanism 4 to comb the infusion tube 6 neatly. If the bottom end of the infusion tube 6 is pulled, the infusion tube 6 will gradually detach from the infusion tube combing mechanism 4, avoiding the needle from detaching from the patient's body when the infusion tube 6 is pulled.
[0040] For example 2, please refer to Figures 1 to 13 This embodiment provides a technical solution: an IV stand for an intensive care unit. The structure of this embodiment is roughly the same as that of the first embodiment, except that a structure for combing and winding the IV tube 6 is added. Specifically: The infusion tube combing mechanism 4 also includes a top plate 418, a bottom plate 420, a fixed column 421, a combing cross cylinder 422, a baffle 423, a folding winding assembly and a distance adjustment assembly. The side of the adjustment sleeve 41 away from the beam 43 is fixedly connected to the top of the top plate 418, and the bottom of the top plate 418 is connected to the bottom plate 420 through the distance adjustment assembly. The side of the top plate 418 away from the infusion support rod 1 is fixedly connected with the fixed column 421, and the outer side of the fixed column 421 is rotatably sleeved with a combing cross cylinder 422. Two baffle rings 423 are respectively provided at both ends of the combing cross cylinder 422, and a folding winding assembly is installed on the side of the bottom plate 420 away from the infusion support rod 1.
[0041] The distance adjustment assembly includes a vertical telescopic rod 419, a screw 424, a screw nut 425 and a knob 426. The bottom of the top plate 418 is fixedly connected to the top of the bottom plate 420 through two vertical telescopic rods 419. The arrangement of the two vertical telescopic rods 419 allows the bottom plate 420 to move up and down only relative to the top plate 418. The bottom center of the top plate 418 is connected to the top of the screw 424 through a bearing. A screw nut 425 is provided in the middle of the bottom plate 420. The screw nut 425 cooperates with the screw 424 to connect. The bottom end of 424 is fixedly connected with a knob 426. With the help of knob 426, the screw 424 is rotated clockwise, and the threaded action of the screw 424 and the screw nut 425 drives the bottom plate 420 to move upward, and the vertical telescopic rod 419 is shortened, thereby reducing the distance between the bottom plate 420 and the top plate 418. With the help of knob 426, the screw 424 is rotated counterclockwise, and the threaded action of the screw 424 and the screw nut 425 drives the bottom plate 420 to move downward, and the vertical telescopic rod 419 is extended, thereby increasing the distance between the bottom plate 420 and the top plate 418.
[0042] The distance adjustment component is used to change the distance between the top plate 418 and the bottom plate 420. When the distance between the top plate 418 and the bottom plate 420 becomes larger, the length of the liquid infusion tube 6 wound around the combing horizontal cylinder 422 and the folding winding assembly will increase. When the distance between the top plate 418 and the bottom plate 420 decreases, the length of the liquid infusion tube 6 wound around the combing horizontal cylinder 422 and the folding winding assembly will decrease. The combing horizontal cylinder 422 can rotate relative to the fixed column 421, and the liquid infusion tube 6 rolls in contact with the combing horizontal cylinder 422, reducing the distance between the liquid infusion tube 6 and the combing horizontal cylinder 422. The friction force when the combing horizontal cylinder 422 contacts the retaining ring 423 limits the outer peripheral sides of the two ends of the combing horizontal cylinder 422 to prevent the infusion tube 6 from detaching from the end of the combing horizontal cylinder 422. The infusion tube 6 is wound between the combing horizontal cylinder 422 and the folding winding assembly. When the bottom of the infusion tube 6 is pulled, the folding winding assembly folds upward, so that the infusion tube 6 wound between the combing horizontal cylinder 422 and the folding winding assembly can be released. If the pulling length is too large, the infusion tube 6 will detach from the end of the folding winding assembly, releasing a longer infusion tube 6.
[0043] The folding winding assembly includes a round seat 427, a movable shaft 428, a combing slide 430 and a folding column 431. A round seat 427 is provided on the side of the base plate 420 away from the infusion support rod 1. The round seat 427 is movably connected to one end of the folding column 431 through the movable shaft 428. The combing slide 430 is slidably sleeved on the outer side of the folding column 431, and the combing slide 430 is connected to the folding column 431 through an anti-detachment assembly.
[0044] The anti-separation component includes a limiting end cover 429, a transverse limiting groove 432 and an anti-separation protrusion 433. A transverse limiting groove 432 is provided at the end of the folding column 431 away from the movable shaft 428, and the transverse limiting groove 432 extends to the end face of the folding column 431. The inner side of the combing slide 430 is provided with an anti-separation protrusion 433 that is slidably connected to the transverse limiting groove 432. The end of the folding column 431 away from the movable shaft 428 is threadedly connected to the limiting end cover 429. The limiting end cover 429 blocks the end of the transverse limiting groove 432. The setting of the limiting end cover 429 prevents the anti-separation protrusion 433 from being disengaged from the transverse limiting groove 432, thereby preventing the combing slide 430 from being disengaged from the folding column 431.
[0045] When it is necessary to wind the infusion tube 6 between the combing horizontal cylinder 422 and the combing slide 430, the combing slide 430 is slid relative to the folding column 431, and the end of the combing slide 430 is sheathed on the round seat 427. At this time, the folding column 431 can no longer move relative to the round seat 427 through the movable shaft 428, and the infusion tube 6 can be quickly and stably wound between the combing horizontal cylinder 422 and the combing slide 430. Due to the gravity of the infusion tube 6, the infusion tube 6 is easily squeezed and deformed when it contacts the top of the combing horizontal cylinder 422, which will cause a certain degree of deformation. The degree of infusion efficiency of the infusion tube 6 is affected. By shortening the distance between the combing horizontal cylinder 422 and the combing slide 430 with the help of the distance adjustment component, this problem can be solved to a certain extent. After the infusion tube 6 is wound between the combing horizontal cylinder 422 and the combing slide 430, the combing slide 430 is slid relative to the folding column 431 to allow the round seat 427 and the movable shaft 428 to leak out. The folding column 431 and the combing slide 430 can move relative to the round seat 427 through the movable shaft 428. At this time, the state of the folding winding component can be referred to. Figure 12 If the bottom of the infusion tube 6 is pulled, the combing slide 430 and the folding column 431 move relative to the round seat 427 through the movable shaft 428, and the combing slide 430 and the folding column 431 are folded upward away from the round seat 427, so that a part of the infusion tube 6 wound between the combing horizontal cylinder 422 and the combing slide 430 can be released. At this time, the state of the folding winding assembly can be referred to Figure 13 If the infusion tube 6 is continued to be pulled, the infusion tube 6 wound around the right end of the combing slide 430 will break away from the combing slide 430, releasing the longer infusion tube 6.
[0046] For example three, please refer to Figures 1 to 13 This embodiment provides a technical solution: an IV stand for an intensive care unit. The structure of this embodiment is roughly the same as that of the second embodiment, except that: An infusion tube elastic clamping mechanism 5 is also provided, which includes an adjustment sleeve 2 51, a butterfly bolt 2 52, a support plate 53, a clamping plate 54, a positioning movable column 55, a fan-shaped clamping block 56 and a clamping elastic control component. The bottom of the infusion support rod 1 is sleeved with an adjustment sleeve 2 51, and the adjustment sleeve 2 51 is fixedly connected to the infusion support rod 1 through the butterfly bolt 2 52. Two longitudinal support plates 53 are fixedly connected on both sides of the adjustment sleeve 2 51, each The rear sides of the support plates 53 are fixedly connected with clamping plates 54, and a circular arc structure protruding backward is provided in the middle of the clamping plates 54. The support plates 53 are movably connected to the top of the fan-shaped clamping block 56 through a horizontal positioning movable column 55. The circular arc surface on the rear side of the fan-shaped clamping block 56 corresponds to the middle front side of the clamping plate 54, and circular arc grooves are provided in the middle of the circular arc surface of the fan-shaped clamping block 56 and the middle of the front side of the clamping plate 54. The front end of the fan-shaped clamping block 56 is connected to the clamping elastic control component.
[0047] The height of the adjustment sleeve 51 can be adjusted by loosening the butterfly bolt 52 , and then the adjustment sleeve 51 and the infusion support rod 1 can be re-fixed by tightening the butterfly bolt 52 .
[0048] The clamping elastic control component includes a slide 57, a sliding control column 58, a clamping compression spring 59 and a button 510. The front side of the support plate 53 is movably connected to the slide 57 through a short axis. The sliding control column 58 is inserted into the through hole on the slide 57. The rear end of the sliding control column 58 is movably connected to the front end of the fan-shaped clamping block 56 through a pin shaft. The front end of the sliding control column 58 is installed with a button 510, and the column section of the sliding control column 58 located between the button 510 and the slide 57 is sleeved with a clamping compression spring 59.
[0049] The slide 57 can move relative to the support plate 53 as the angle of the sliding control column 58 changes. The elastic force of the clamping compression spring 59 pushes the button 510 and the sliding control column 58 to move downward, thereby pulling the front end of the fan-shaped clamping block 56 downward, allowing the arc surface of the fan-shaped clamping block 56 to approach the arc structure part in the middle of the clamping plate 54, so that the infusion tube 6 is clamped by the arc surface of the fan-shaped clamping block 56 and the clamping plate 54. When the infusion tube 6 needs to be manually released, press the button 510 upward, the clamping compression spring 59 is compressed, and the sliding control column 58 is used to push the front end of the fan-shaped clamping block 56 upward, so that the back side of the fan-shaped clamping block 56 can move downward, and the fan-shaped clamping block 56 gradually leaves the clamping plate 54, losing the clamping effect on the infusion tube 6.
[0050] The clamping elastic control component elastically pushes the front end of the fan-shaped clamping block 56 upward, allowing the fan-shaped clamping block 56 to move relative to the positioning movable column 55, so that the arc surface of the fan-shaped clamping block 56 is close to the arc structure part in the middle of the clamping plate 54, and the infusion tube 6 passes between the arc surface of the clamping plate 54 and the fan-shaped clamping block 56. The specific relative structure can be seen Figure 3 Due to the arc grooves in the middle of the arc surface of the fan-shaped clamping block 56 and the middle of the front side of the clamping plate 54, the arc surface of the clamping plate 54 and the fan-shaped clamping block 56 can prevent the infusion tube 6 from being clamped flat and affecting the infusion. If the bottom end of the infusion tube 6 is pulled, the front end of the fan-shaped clamping block 56 overcomes the elastic force of the clamping elastic control component, and the rear side of the fan-shaped clamping block 56 moves downward. The fan-shaped clamping block 56 gradually leaves the clamping plate 54 and loses the clamping effect on the infusion tube 6. The infusion tube 6 moves downward relative to the clamping plate 54, which can release a longer infusion tube 6, shortening the reserved length of the infusion tube between the infusion stand and the patient, avoiding entanglement with other pipelines and causing confusion during use. When the infusion tube is pulled, the combed infusion tube can be released to avoid tearing the tape and causing the needle to fall off the patient.
[0051] Due to the addition of the infusion tube elastic clamping mechanism 5, the infusion tube 6 can be prevented from being released from the infusion tube combing mechanism 4 due to a very small pulling force. Only when the pulling force reaches a certain level and overcomes the clamping effect of the infusion tube elastic clamping mechanism 5 on the infusion tube 6, can the infusion tube combing mechanism 4 start to release the entangled infusion tube 6.
