Description

Technical Field

[0001] The present invention relates to the field of medical instruments, and more particularly to a mobile multifunctional infusion stand. Background Art

[0002] The mobile multifunctional infusion stand is a movable device used in medical institutions or home care. Its main function is to provide support for hanging infusion bags or infusion bottles during the infusion process.

[0003] Most of the infusion stands in the prior art are composed of a base with universal wheels, an adjustable telescopic rod fixedly connected to the base, and a hook part fixedly connected to the telescopic rod. Generally, when in use, a single infusion bottle or infusion bag is usually hung on the hook. When the liquid medicine in the infusion bottle or infusion bag is used up, the nurse takes a new infusion bottle or infusion bag and replaces the empty infusion bottle or infusion bag on the hook. Although this method allows the nursing staff and the patient to clearly know the type of medicine or liquid currently infused to avoid confusion, it requires the nurse to replace the infusion bottle or infusion bag on the hook many times. Of course, multiple liquid bags or liquid bottles can also be hung on multiple hooks respectively. In this way, after the liquid medicine in one of the liquid bags or liquid bottles is clean, the nurse only needs to rotate the hook and insert the infusion set into the liquid bag or liquid bottle containing the liquid medicine inside to continue the infusion, without the need to carry the liquid bag or liquid bottle for replacement every time;

[0004] Although infusion can be facilitated by hanging multiple liquid bags or liquid bottles on the hook, the distribution and load of the hook will be unbalanced (the liquid bags or liquid bottles without liquid medicine and the liquid bags or liquid bottles containing liquid medicine are unbalanced on the hook), which may cause the stand to tilt or become unstable, especially when adjusting the height of the infusion stand (when the nurse's hand cannot take the liquid bag or liquid bottle on the hook, the infusion stand needs to be lowered, and after the infusion set is inserted into another liquid bag or liquid bottle, the infusion stand needs to be raised) or when the hook is rotated, the entire stand may lose balance or even fall over. Summary of the invention

[0005] In view of the problems existing in the prior art, the object of the present invention is to provide a mobile multifunctional infusion stand.

[0006] To solve the above problems, the present invention adopts the following technical solutions.

[0017] Furthermore, the limit and anti-sway assembly includes a wire groove opened in the seat body and the protective plate for the movement of the wire body, a guide wheel rotatably connected to one side of the seat body and the inside of the protective plate for guiding the wire body, a take-up wheel rotatably connected to the inside of the seat body and connected to the other end of the wire body for retracting and releasing the wire body, a gear four rotatably connected to the outer surface of one side of the seat body and fixed to one side of the take-up wheel, a knob plate fixed to the other side of the gear four, a support plate fixed to the outer surface of one side of the seat body, a movable seat three slidably connected to the outer surface of one side of the seat body, a screw three screwed in the support plate, and a limit extension part integrally formed at the lower end of the movable seat three for limiting the gear four, and the lower end of the screw three is rotatably connected to the upper end of the movable seat three.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) The present solution is provided with a plurality of pre-mounting adjustment components, on which a plurality of liquid bags or liquid bottles can be mounted respectively, thereby improving the use efficiency. Nurses do not need to carry liquid bags or liquid bottles for replacement when changing liquids, and the hook has a height adjustment function. The mounted unused liquid bags or liquid bottles are at the bottom of the rod body under normal conditions, thereby lowering the load center of gravity of the rod body. At the same time, the hook has a lifting function, and there is no need to manually adjust the height of the infusion stand. When the center of gravity is low, the stability of the infusion stand is enhanced. Even when the rod body is rotated and the hook is controlled to drive the liquid bag or liquid bottle to rise, the center of gravity is at the bottom, and the possibility of tilting or collapse is greatly reduced, thereby reducing the risk of tilting or tipping and making the infusion stand more stable. Since the liquid bag or liquid bottle is pre-mounted on the hook at a lower position, the nursing staff does not need to lift heavy objects to operate, thereby reducing the unstable factors in the operation and the risk of the infusion stand tilting during the mounting process. When the center of gravity is at the lowest point, the shaking and imbalance caused by the loading of the liquid bag will be easier to control.

[0020] (2) The present invention is provided with a mounting extension part, which adopts a design in which the frame is rotatably connected to the base. When the frame is parallel to the base, when the liquid bag or small-volume liquid bottle is hung on the hook, the distance between the liquid bag or small-volume liquid bottle and the rod is close, and the center of gravity is more concentrated, thereby avoiding the situation in which the center of gravity is shifted. When the hook rises and drives the liquid bag to rise, the liquid bag will not shake or swing easily, which helps to improve the stability of the infusion stand and avoid the liquid bag shaking drastically during the lifting process, causing the infusion tube to be pulled, or the infusion stand to be unbalanced. When the frame is rotated and perpendicular to the base, the hook can mount a liquid bottle that is larger than the liquid bag, which is convenient for mounting liquid bottles of different sizes, especially large-capacity liquid bottles, thereby ensuring the stability of the infusion stand while also ensuring the applicability of the infusion stand.

[0021] (3) The present solution is provided with a positioning unit. Since the hook is connected to the frame body through a rotating turntable, when the frame body is perpendicular to the base body and a liquid bottle is mounted, the connecting rods 1 and 2 are rotated and unfolded. The rotation of the connecting rod 2 can drive the sliding seat and the pressure plate to move toward the turntable, so that the two pressure plates respectively apply pressure to the two turntables on both sides of the hook, making the turntable unable to rotate. This can prevent the hook from shaking when carrying a liquid bottle or a liquid bag, especially when a heavier liquid bottle is mounted. The shaking of the hook may cause the liquid bottle to swing, affecting the stability of the infusion stand and reducing the risk of the liquid bottle sliding or falling off, thereby greatly improving the safety of the infusion process.

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0037] See also Figures 1 to 12 A mobile multifunctional infusion stand comprises a pillar 1, a base 2 integrally formed with the lower end of the pillar 1, a plurality of universal wheels connected to the lower end of the base 2, and a rod body 3 connected to the upper end of the pillar 1, wherein a counterweight portion 33 is rotatably connected inside the pillar 1, and a positioning portion 32 is fixedly connected to the upper end of the counterweight portion 33, and the upper end of the positioning portion 32 passes through the pillar 1 and is fixedly connected to the lower end of the rod body 3, and a disc body 34 is also fixedly connected to the lower end of the counterweight portion 33, and the disc body 34 is rotatably connected to the inside of the pillar 1, and a positioning component 4 for positioning the positioning portion 32 is also connected inside the pillar 1;

[0038] A plurality of movable grooves three 31 are provided inside the rod body 3, and a plurality of pre-mounting adjustment components 5 are respectively connected to the plurality of movable grooves three 31, and the pre-mounting adjustment components 5 include a screw rod 52 rotatably connected in the movable groove three 31, a seat body 51 slidably connected in the movable groove three 31 and screwed to the outside of the screw rod 52, a frame body 56 connected to one side of the seat body 51, a slot body provided inside the frame body 56, two turntables 58 symmetrically rotatably connected to the inner wall of the slot body, a hook 57 fixedly connected to the two turntables 58 on both sides, a motor 54 fixedly connected to the inside of the rod body 3, a gear two 55 rotatably connected to the inside of the rod body 3 and connected to the output shaft of the motor 54, a gear one 53 rotatably connected in the rod body 3 and meshing with the gear two 55, and the lower end of the screw rod 52 is fixedly connected to the gear one 53.

[0039] The positioning assembly 4 includes a screw rod 42 threadedly connected to the inside of the pillar 1, a moving seat 43 slidably connected to the inside of the pillar 1, a positioning flange 44 integrally formed on one side of the moving seat 43, and the other side of the moving seat 43 is rotatably connected to one end of the screw rod 42, and a positioning groove 41 capable of accommodating the positioning flange 44 is opened on the outer surface of the positioning portion 32.

[0040] By adopting the above technical solution, a plurality of liquid bags or liquid bottles are hung on a plurality of hooks 57 in advance, and then one of the motors 54 is controlled to rotate to drive the gear 2 55 and the gear 1 53 to rotate, the gear 1 53 rotates to drive the screw rod 52 to rotate, the screw rod 52 rotates to drive the seat body 51 in one of the movable grooves 31 to move upward, and when the seat body 51 moves upward in the movable groove 31, it drives the liquid bag or liquid bottle mounted on the hook 57 to move upward, so that the liquid bag or liquid bottle connected to the infusion set is raised to facilitate the infusion. Infusion, the liquid bags and liquid bottles on the other hooks 57 can be located at the bottom of the rod body 3, and there is only one liquid bag or liquid bottle that is being discharged at the upper end of the rod body 3, which effectively reduces the load center of gravity of the rod body 3. When the center of gravity is low, the stability of the infusion stand is enhanced. After the liquid bag or liquid bottle at the upper end of the rod body 3 is emptied, the control motor 54 rotates and lowers the hook 57 with the empty liquid bag or liquid bottle, and then rotates the screw rod 42, which drives the moving seat 43 to move in the direction of the screw rod 42, and the positioning flange 44 The rod 3 is then moved out of the positioning groove 41, and the infusion device plug is pulled out from the empty liquid bag or liquid bottle. The rod body 3 is then rotated to insert the infusion device plug into another liquid bag or liquid bottle, and the other motor 54 is controlled to work to drive the other liquid bag or liquid bottle to rise, and the screw rod 42 is then rotated to make the positioning flange 44 reinsert into the positioning groove 41 to limit the rod body 3, so as to achieve the replacement of the liquid bag or liquid bottle. In this way, after a single liquid bag is emptied, the nurse does not need to carry the liquid bag or liquid bottle for replacement every time when replacing it. At the same time, when the rod body 3 is rotated and the hook 57 is controlled to drive the liquid bag or liquid bottle to rise, the center of gravity is located at the bottom, and the possibility of tilting or collapse is greatly reduced, reducing the risk of tilting or tipping, making the infusion stand more stable. Since the liquid bag or liquid bottle is pre-mounted on the hook 57 at a lower position, the nursing staff does not need to lift heavy objects to operate, which reduces the unstable factors in the operation and the risk of the infusion stand tilting during the mounting process. When the center of gravity is at the lowest point, the shaking and imbalance caused by the loading of the liquid bag will be easier to control.

[0041] like Figure 5 - Figure 8 As shown, the frame body 56 is rotatably connected to one side of the seat body 51, a movable groove 511 is opened on one side of the seat body 51, and a mounting extension part 6 is connected in the movable groove 511, and the mounting extension part 6 includes a connecting rod 61 whose one end is rotatably connected to the inner wall of the movable groove 511, two connecting rods 62 whose one end is rotatably connected to one side of the frame body 56, a movable groove 611 opened inside the other end of the connecting rod 61, a ratchet 63 located inside the movable groove 611 and fixed to the two connecting rods 62 at both ends, a limiting part connected to the inside of the other end of the connecting rod 61 and limiting the ratchet 63, and the other ends of the two connecting rods 62 are rotatably connected to the two sides of the connecting rod 61 respectively.

[0042] The limiting portion includes a screw rod 2 64 threadedly connected to the other end of the connecting rod 1 61, a moving seat 2 65 slidably connected to the other end of the connecting rod 1 61, and a limiting flange 66 integrally formed on one side of the moving seat 2 65, and one end of the screw rod 2 64 is rotatably connected to one side of the moving seat 2 65.

[0043] One ends of the two connecting rods 62 are connected via a connecting rod 67 , and the connecting rod 67 is rotatably connected inside the frame 56 .

[0044] By adopting the above technical solution, when the frame 56 is parallel to the seat 51, the liquid bag or the small-volume liquid bottle is hung on the hook 57, and the distance between the liquid bag or the small-volume liquid bottle and the rod 3 is close, the center of gravity is more concentrated, and the center of gravity shift is avoided. When the hook 57 rises and drives the liquid bag to rise, the liquid bag will not shake or swing easily, which helps to improve the stability of the infusion stand and avoid the liquid bag shaking greatly during the lifting process, causing the infusion tube to be pulled, or the infusion stand to be unbalanced. When the frame 56 is rotated and perpendicular to the seat 51, the connecting rod 1 61 and the connecting rod 2 62 are moved out of the movable groove 1 511, and one end of the connecting rod 1 61 rotates clockwise on the inner wall of the movable groove 1 511, and the connecting rod 2 62 The end connected to the connecting rod 1 61 rotates counterclockwise relative to the connecting rod 1 61, and the end of the connecting rod 2 62 connected to the frame 56 also rotates counterclockwise relative to the frame 56, and the screw 2 64 is rotated. The screw 2 64 drives the movable seat 2 65 to move in the direction of the ratchet 63, so that the limiting flange 66 limits the ratchet 63. At this time, the connecting end of the connecting rod 2 62 and the connecting rod 1 61 cannot rotate clockwise in the movable groove 2 611, thereby supporting the frame 56 perpendicular to the seat 51. The unfolded hook 57 can mount liquid bottles of larger volume, which is convenient for mounting liquid bottles of different sizes, especially large-capacity liquid bottles, ensuring the stability of the infusion stand while also ensuring the applicability of the infusion stand.

[0045] like Fig. 9 As shown, the frame 56 is internally connected with a positioning unit 7, and the positioning unit 7 includes a sprocket 1 71 fixedly connected to the outside of the connecting rod 67, a sprocket 2 73 rotatably connected to the frame 56, a chain belt 72 connecting the sprocket 1 71 with the sprocket 2 73, two bevel gears 1 74 symmetrically fixedly connected to both sides of the sprocket 2 73, two bevel gears 2 75 rotatably connected to the frame 56 and respectively connected to the two bevel gears 1 74 for transmission, a synchronous wheel 1 76 fixedly connected to one side of the two bevel gears 2 75, two rotating shafts 78 symmetrically rotatably connected to the frame 56, two gears 3 79 and two synchronous wheels 2 respectively fixed to the outside of the two rotating shafts 78, a synchronous belt 77 connecting the synchronous wheel 1 76 with the synchronous wheel 2, two slides 8 symmetrically slidably connected to the frame 56, a tooth key 81 opened at the upper ends of the two slides 8 and meshing with the gear 3 79, and two pressure plates 82 respectively fixedly connected to one side of the two slides 8.

[0046] One side of the two pressure plates 82 and one side of the two rotating plates 58 are both provided with anti-slip grooves.

[0047] By adopting the above technical solution, when one end of the connecting rod 2 62 connected to the frame 56 rotates counterclockwise, the connecting rod 67 connected to one end of the two connecting rods 2 62 also rotates counterclockwise, and the sprocket 1 71 on the connecting rod 67 drives the sprocket 2 73 to rotate counterclockwise through the chain belt 72. The rotation of the sprocket 2 73 drives the two bevel gears 1 74 to rotate counterclockwise. The rotation of the two bevel gears 1 74 drives the two bevel gears 2 75 to rotate clockwise respectively. The rotation of the two bevel gears 2 75 drives the synchronous wheel 1 76 to rotate. The synchronous wheel 1 76 rotates and drives the synchronous wheel 2 and the rotating shaft 78 to rotate through the synchronous belt 77. The rotation of the rotating shaft 78 drives the gear 3 79 to rotate. The gear 3 79 The rotation drives the slide 8 to move toward the turntable 58, so that the pressure plate 82 on one side of the slide 8 applies pressure to the turntable 58. The anti-skid pattern on one side of the pressure plate 82 contacts the anti-skid pattern on one side of the turntable 58, thereby increasing the contact friction, making it impossible for the turntable 58 to rotate, and the hook 57 also cannot rotate. In this way, when the frame 56 is perpendicular to the seat body 51, the hook 57 cannot rotate within the frame 56, thereby preventing the hook 57 from shaking when carrying a liquid bottle or a liquid bag, especially when a heavier liquid bottle is mounted, the shaking of the hook 57 may cause the liquid bottle to swing, affecting the stability of the infusion stand and reducing the risk of the liquid bottle sliding or falling off, thereby greatly improving the safety of the infusion process.

[0048] like Figure 5 , Fig.10 - Fig.12 As shown, a protective plate 10 is fixedly connected to one side of the seat body 51, and a wire body 11 is connected to one side of the protective plate 10. One end of the wire body 11 is fixedly connected to the outer surface of one side of the protective plate 10, and the other end of the wire body 11 passes through the protective plate 10 and is connected to the limiting anti-sway component 9 inside the seat body 51.

[0049] The position limiting and anti-swaying assembly 9 includes a wire groove 91 provided inside the seat body 51 and the protective plate 10 for the movement of the wire body 11, a guide wheel 92 rotatably connected to one side of the seat body 51 and the inside of the protective plate 10 for guiding the wire body 11, a take-up wheel 93 rotatably connected to the inside of the seat body 51 and connected to the other end of the wire body 11 for retracting and releasing the wire body 11, a gear four 94 rotatably connected to the outer surface of one side of the seat body 51 and fixed to one side of the take-up wheel 93, a knob plate 95 fixed to the other side of the gear four 94, a support plate 96 fixed to the outer surface of one side of the seat body 51, a movable seat three 98 slidably connected to the outer surface of one side of the seat body 51, a screw three 97 screwed in the support plate 96, and a position limiting extension portion integrally formed at the lower end of the movable seat three 98 for limiting the gear four 94, and the lower end of the screw three 97 is rotatably connected to the upper end of the movable seat three 98.

[0050] By adopting the above technical solution, when the liquid bag or liquid bottle is hung on the hook 57, the wire body 11 can be put on the outside of the liquid bag or liquid bottle, and then the screw three 97 is rotated to drive the movable seat three 98 to move toward the direction of the support plate 96, and the limit on the gear four 94 is cancelled. Then the knob plate 95 is rotated, and the knob plate 95 rotates to drive the take-up wheel 93 to rotate through the gear four 94, and the take-up wheel 93 reels the wire body 11. When the wire body 11 is tightened, it can tighten the liquid bag or liquid bottle, effectively preventing the liquid bag or liquid bottle from shaking, and improving the stability of the infusion stand.

[0051] Method of use: Pre-hang multiple liquid bags or liquid bottles on multiple hooks 57 respectively, then control one of the motors 54 to rotate and drive the gear 2 55 and the gear 1 53 to rotate, the gear 1 53 rotates and drives the screw 52 to rotate, the screw 52 rotates and drives the seat body 51 in one of the movable grooves 31 to move upward, and when the seat body 51 moves upward in the movable groove 31, it drives the liquid bag or liquid bottle mounted on the hook 57 to move upward, so that the liquid bag or liquid bottle connected to the infusion set is raised for easy infusion, and the liquid bags and liquid bottles on the remaining hooks 57 can be located At the bottom of the rod body 3, after the liquid bag or liquid bottle at the upper end of the rod body 3 is emptied, the motor 54 is controlled to rotate and the hook 57 with the empty liquid bag or liquid bottle is lowered, and then the screw 42 is rotated, and the screw 42 drives the moving seat 43 to move in the direction of the screw 42, and the positioning flange 44 is moved out of the positioning groove 41, and the infusion device plug is pulled out of the empty liquid bag or liquid bottle, and then the rod body 3 is rotated, and the plug of the infusion device is inserted into another liquid bag or liquid bottle, and then another motor 54 is controlled to work to drive another liquid bag or liquid bottle to rise, and then the screw 42 is rotated to make the positioning flange 44 is reinserted into the positioning groove 41 to limit the rod body 3, so as to realize the replacement of the liquid bag or liquid bottle. When the volume of the liquid bottle is large, the frame body 56 is rotated to make the frame body 56 perpendicular to the seat body 51, the connecting rod 1 61 and the connecting rod 2 62 are moved out of the movable groove 1 511, and the screw 2 64 is rotated. The screw 2 64 drives the movable seat 2 65 to move in the direction of the ratchet 63, so that the limiting flange 66 limits the ratchet 63. At this time, the connecting end of the connecting rod 2 62 and the connecting rod 1 61 cannot rotate clockwise in the movable groove 2 611, thereby the frame body 5 perpendicular to the seat body 51 is fixed. 6 is supported, and the unfolded hook 57 can mount a liquid bottle of a larger volume. When the connecting rod 2 62 rotates, it can also drive the sliding seat 8 and the pressure plate 82 to move toward the turntable 58. The pressure plate 82 applies pressure to the turntable 58, and the anti-skid pattern on one side of the pressure plate 82 contacts the anti-skid pattern on one side of the turntable 58, thereby increasing the contact friction, so that the turntable 58 cannot rotate, and the hook 57 cannot rotate either. In this way, when the frame 56 is perpendicular to the seat body 51, the hook 57 cannot rotate in the frame 56, which can prevent the hook 57 from shaking when carrying a liquid bottle or a liquid bag.
