Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a foldable infusion stand. Background Technology

[0002] An IV stand is an auxiliary tool used to administer intravenous infusions to patients. When in use, the medication is suspended at the top of the IV stand, and the medication flows into the patient's body from top to bottom through a disposable IV set.

[0003] However, the support legs at the bottom of the existing IV stand cannot be retracted after use, taking up a lot of space. Also, the IV stand cannot be fixed to the hospital bed. Therefore, the IV stand needs to be dragged back and forth when it is needed and after use. Moreover, when the IV stand needs to be moved, it is moved by the handle in the middle of the IV stand. However, the handle cannot be retracted after use, taking up a lot of storage space. Utility Model Content

[0004] The present invention aims to overcome the shortcomings of the existing technology, such as the inability to retract the support legs at the bottom of the infusion stand after use, which occupies a large space, and the infusion stand not being able to be fixed to the hospital bed. Therefore, the infusion stand needs to be dragged back and forth when needed and after use. Moreover, when the infusion stand needs to be moved, it is moved by the handle in the middle of the infusion stand, but the handle cannot be retracted after use, which occupies a large storage space.

[0005] A foldable infusion stand is proposed, comprising an infusion stand, hooks, a handle assembly, a support assembly, and a sliding device. The hooks are four in number and are all connected to the top of the infusion stand. The handle assembly is horizontally positioned in the middle of the infusion stand and is slidably connected to the infusion stand. The support assembly is located below the handle assembly and is connected to the inside of the infusion stand. The sliding device is located at the bottom of the infusion stand and is connected to the inside of the sliding device.

[0006] In this utility model, the lower end of the IV stand is equipped with a support assembly. When the IV stand needs to be moved, simply press down on the sliding block. The support assembly will then open the rotating rod outwards. After the rotating rod is opened, the casters on the rotating rod will directly contact the ground, allowing the IV stand to be moved via the casters. After use, the support assembly can be stored inside the IV stand, saving space. After the support assembly is stored, the lower end of the IV stand is inserted into the sliding device. The IV stand can then be connected to the bed via the sliding device, eliminating the need to drag the IV stand. To move the IV stand, rotate the handle upwards until it is parallel to the fixed handle, then it can be moved. Move the IV stand using the handle. After the IV stand is moved to the desired position, pull the pull cord upwards and then rotate the handle downwards. Stop rotating the handle when the angle between the rotating handle and the fixed handle is 90 degrees. At this point, the rotating arm will be folded and stored away. This solves the problem mentioned in the technical background that the support legs at the bottom of the existing IV stand cannot be stored away after use, taking up a lot of space. Also, the IV stand cannot be fixed to the hospital bed. Therefore, the IV stand needs to be dragged back and forth when it is needed and after use. Moreover, when the IV stand needs to be moved, it is moved by the handle in the middle of the IV stand. However, the handle cannot be stored away after use, taking up a lot of storage space.

[0007] In a preferred embodiment of the present invention, the infusion stand includes a vertical pole, a connecting rod, and a first bolt. The bottom end of the connecting rod is connected to the inside of the vertical pole, and the hook is connected to the top end of the connecting rod. The first bolt is horizontally disposed at the top end of the vertical pole and connected to the connecting rod. The support assembly and the handle assembly are both connected to the vertical pole. When the patient walks, the connecting rod can be opened upward to extend the total length of the infusion stand, thereby ensuring that the height of the hook is always higher than that of the patient.

[0008] In a preferred embodiment of the present invention, the hook is hinged to the connecting rod, and can be rotated upwards and stored away when the hook is no longer in use, thereby reducing the space occupied by the hook.

[0009] In a preferred embodiment of the present invention, the connecting rod is provided with multiple threaded holes. When the connecting rod is pulled out to the required height, the first bolt can be rotated forward until the end of the first bolt is inserted into the pre-set threaded hole of the connecting rod, thereby restricting the position of the connecting rod.

[0010] In a preferred embodiment of the present invention, the handle assembly includes a sliding handle, a rotating handle, a second bolt, a ratchet, a ratchet tooth, a pull rope, and a magnet. The sliding handle is sleeved on the upright post. The second bolt is located on one side of the upright post and connected to the sliding handle. The rotating handle is hinged to one end of the sliding handle. There are two ratchets, each sleeved on the hinge shaft of the rotating handle. Each ratchet has a ratchet tooth above it, and a magnet is connected to the end of each ratchet tooth. The pull rope is located above the sliding handle, and both ends of the pull rope are connected to the two ratchet teeth respectively. When the ratchet teeth rotate upward under the action of the pull rope, the magnet will be attracted to the ratchet teeth by magnetic force when the pull rope is released, thereby causing the ratchet teeth to rotate downward until the ends of the ratchet teeth re-engage with the ratchet tooth grooves, thus stopping the ratchet teeth from rotating further.

[0011] In a preferred embodiment of the present invention, the support assembly includes four rotating rods, a rotating rod, a sliding block, and a pin. Four rotating rods are arranged around the perimeter of the upright, and each of the four rotating rods has a rotating rod above it. Both ends of the rotating rods are connected to the rotating rod and the upright, respectively. The other ends of the four rotating rods are connected to the sliding block. The pin is horizontally positioned on the sliding block and connected to the upright. The sliding block is slidably connected to the upright. When the sliding block moves downwards, it opens the four rotating rods outwards, allowing the opened rotating rods to support the upright and prevent it from tipping over.

[0012] In a preferred embodiment of the present invention, each of the four rotating rods is provided with a universal wheel. The universal wheels are brake-type universal wheels, which can be used to restrict the position of the infusion stand after it has been moved to the required position.

[0013] In a preferred embodiment of the present invention, the upright is provided with four grooves at the position of the sliding block, and each of the four grooves is provided with a spring. The two ends of the spring are respectively connected to the upright and the sliding block. When the sliding block moves up and down, the groove can guide the sliding block.

[0014] In a preferred embodiment of the present invention, the upright has a fixing hole corresponding to the pin. When the sliding block moves to the desired position, the pin can be inserted into the fixing hole to restrict the position of the sliding block.

[0015] In a preferred embodiment of the present invention, the sliding device includes a fixed cylinder, a guide block, and a third bolt. The fixed cylinder is vertically disposed on one side of the guide block and slidably connected to the guide block. The third bolt is located on one side of the fixed cylinder and threadedly connected to the fixed cylinder. After the infusion stand is used, it can be connected to the hospital bed through the sliding device, thus facilitating its use when the patient is lying in bed.

[0016] The advantages of this utility model compared with the prior art are: After use, the support component at the bottom of the IV stand can be stored inside the stand, reducing its storage space. Once the support component is stored, the stand can be connected to the bed via a sliding mechanism, eliminating the need to push it into storage. Therefore, when the stand is needed, it does not need to be pulled back. The stand can be pushed using the handle component, and after it reaches the desired position, the handle component can be folded away to avoid obstructing pedestrians. After use, the hook at the top of the stand can be rotated upwards and stored away, further reducing its space requirements. Attached Figure Description

Detailed Implementation

[0018] The following will refer to the appendix in the embodiments of this utility model. Figure 1-16 The technical solutions in the embodiments of this utility model will be described in detail below.

[0019] like Figure 1-3 As shown, a foldable infusion stand includes an infusion stand 1, hooks 2, a handle assembly 3, a support assembly 4, and a sliding device 5. There are four hooks 2, all of which are horizontally arranged on the top of the infusion stand 1, and the four hooks 2 are evenly arranged around the perimeter of the infusion stand 1 with the axis of the infusion stand 1 as the center.

[0020] like Figure 1-3 As shown, one end of each of the four hooks 2 is hinged to the IV stand 1. Therefore, when the hooks 2 are no longer in use, they can be rotated upwards and stored away to reduce the space occupied by the hooks 2. The handle assembly 3 is horizontally positioned in the middle of the IV stand 1.

[0021] like Figure 1-3 As shown, when moving the IV stand 1, the IV stand 1 can be moved by pushing it with the handle assembly 3. The handle assembly 3 is slidably connected to the IV stand 1, so the height of the handle assembly 3 can be adjusted according to the user's height.

[0022] like Figure 1-3 As shown, the support component 4 is located below the handle component 3 and is set in a preset groove in the infusion stand 1. When the infusion stand 1 needs to be moved, the support component 4 can be opened, and then the infusion stand 1 can be moved through the support component 4.

[0023] like Figure 1-3 As shown, when the IV stand 1 does not need to be moved, the support component 4 can be stored inside the IV stand 1, thereby reducing the storage space of the IV stand 1. The sliding device 5 is located at the bottom of the IV stand 1, and the IV stand 1 is connected inside the sliding device 5.

[0024] like Figure 1-3As shown, after the IV stand 1 is used up and the support component 4 is stored inside the IV stand 1, the IV stand 1 can be inserted into the sliding device 5. The sliding device 5 is connected to the hospital bed. Therefore, after the IV stand 1 is used up, it can be connected to the hospital bed through the sliding device 5, which makes it convenient for the patient to use while lying in the hospital bed.

[0025] like Figure 4-5 As shown, the IV stand 1 includes a vertical rod 11, a connecting rod 12 and a first bolt 13. The bottom end of the connecting rod 12 is slidably connected to the inside of the vertical rod 11. Therefore, the connecting rod 12 can be pulled out upwards when needed, thereby increasing the total length of the IV stand 1.

[0026] like Figure 4-5 As shown, the four hooks 2 are all hinged to the top of the connecting rod 12, the first bolt 13 is horizontally threaded into the threaded through hole at the top of the upright 11, and the connecting rod 12 has multiple threaded holes vertically at the position of the first bolt 13.

[0027] like Figure 4-5 As shown, after the connecting rod 12 is pulled upward and opened to the required height, the first bolt 13 can be rotated forward until the end of the first bolt 13 is turned into the preset threaded hole of the connecting rod 12, which can restrict the position of the connecting rod 12, and the support component 4 is connected to the bottom end of the upright 11.

[0028] like Figure 6-11 As shown, the handle assembly 3 includes a sliding handle 31, a rotating handle 32, a second bolt 33, a ratchet 34, a ratchet tooth 35, a pull rope 36, and a magnet 37. The sliding handle 31 is horizontally arranged on one side of the upright 11, and one end of the sliding handle 31 is sleeved on the upright 11.

[0029] like Figure 6-11 As shown, one end of the sliding handle 31, which is sleeved on the upright 11, is made of plastic with elastic deformation capability. The second bolt 33 is located on the other side of the upright 11 and is threaded to the plastic end of the sliding handle 31.

[0030] like Figure 6-11 As shown, when the second bolt 33 is rotated in the forward direction, the end of the sliding handle 31 with plastic support will tighten, and the end of the sliding handle 31 will clamp the upright 11 after tightening. At this time, the sliding handle 31 cannot move up and down. Conversely, when the second bolt 33 is rotated in the reverse direction, the end of the sliding handle 31 with plastic support will loosen, and the sliding handle 31 can move up and down.

[0031] like Figure 6-11As shown, the rotating handle 32 is horizontally disposed at the other end of the sliding handle 31, and the rotating handle 32 is hinged to the sliding handle 31. There are two ratchet wheels 34, both of which are sleeved on the hinge shaft of the rotating handle 32, and both ratchet wheels 34 are connected to the rotating handle 32 by a key.

[0032] like Figure 6-11 As shown, when the handle 32 is rotated, it will drive the ratchet 34 to rotate synchronously. Each of the two ratchet 34 has a ratchet 35 on its upper side. One end of each ratchet 35 is hinged to the sliding handle 31, and the other end of each ratchet 35 is equipped with a magnet 37.

[0033] like Figure 6-11 As shown, the magnet 37 is embedded in the pre-set groove of the ratchet 35, the pull rope 36 is located above the sliding handle 31, and both ends of the pull rope 36 pass through the sliding handle 31 and are respectively attached to the ends of the two ratchet teeth 35.

[0034] like Figure 6-11 As shown, when the pull rope 36 is pulled upward, the pull rope 36 will drive the ratchet 35 to rotate upward. When the end of the ratchet 35 is pulled out from the ratchet 34, the ratchet 34 can rotate in the opposite direction. The ratchet 34 is made of a magnetic material (such as iron).

[0035] like Figure 6-11 As shown, when the pull rope 36 is released, the magnet 37 will be attracted to the ratchet 34 by magnetic force, which will then drive the ratchet 35 to rotate downward until the end of the ratchet 35 re-engages into the groove of the ratchet 34, thereby blocking the ratchet 34 and preventing it from continuing to rotate.

[0036] like Figure 12-14 As shown, the support assembly 4 includes a rotating rod 41, a rotating rod 42, a sliding block 43, and a pin 44. There are four rotating rods 41, all of which are located at the bottom of the upright 11, and the four rotating rods 41 are evenly arranged around the upright 11 with the axis of the upright 11 as the center.

[0037] like Figure 12-14 As shown, one end of each of the four rotating rods 41 is hinged to the upright rod 11, and the other end of each of the four rotating rods 41 is connected to a rotating rod 42. The other end of each of the four rotating rods 42 is hinged to a sliding block 43. The upright rod 11 is provided with four sliding grooves 6 at the position of the sliding block 43, and the upright rod 11 is slidably connected in the sliding grooves 6.

[0038] like Figure 12-14 As shown, when the sliding block 43 slides downward, the rotating rod 41 can be opened outward by the rotating rod 42. When the rotating rod 41 is opened outward, the rotating rod 41 will rotate downward with the intersection point of the upright rod 11 and the rotating rod 41 as the center.

[0039] like Figure 12-14 As shown, when the sliding block 43 slides upward, the rotating rod 41 can be stored in the rotating rod 42. When the rotating rod 41 is stored in the rotating rod, it will rotate upward with the intersection point of the upright rod 11 and the rotating rod 41 as the center.

[0040] like Figure 12-14 As shown, until both the rotating rod 41 and the rotating rod 42 are rotated into the interior of the slide groove 6, each of the four rotating rods 41 has a universal wheel 7 at one end of the connecting rod 12. The universal wheel 7 is fixedly connected to the rotating rod 41 by screws, so when the rotating rod 41 is opened outward, it will drive the universal wheel 7 to move together.

[0041] like Figure 12-14 As shown, the sliding block 43 stops rotating downwards once the caster 7 contacts the ground. The caster 7 used is a brake-type caster 7. After the IV stand 1 moves to the required position, the position of the IV stand 1 can be restricted by the caster 7.

[0042] like Figure 12-14 As shown, the pin 44 is horizontally positioned on one side of the sliding block 43 and horizontally positioned in the preset through hole of the sliding block 43. When the sliding block 43 moves up and down, it can drive the pin 44 to move together. After the caster 7 contacts the ground, the end of the pin 44 can be inserted into the preset fixing hole 45 on the upright 11, thereby restricting the position of the sliding block 43.

[0043] like Figure 12-14 As shown, when the sliding block 43 slides upward until the rotating rod 41 and the rotating rod 42 are housed inside the slide groove 6, the end of the pin 44 can be inserted into the preset fixing hole 45 on the upright rod 11 to restrict the position of the sliding block 43.

[0044] like Figure 12-14 As shown, each of the four sliding grooves 6 has a spring 61 installed vertically inside. The spring 61 is a tension spring, and the two ends of the spring 61 are connected to the upright rod 11 and the sliding block 43 respectively. Therefore, when the sliding block 43 moves downward, it will pull the spring 61.

[0045] like Figure 12-14 As shown, at this time, the spring 61 will undergo elastic deformation and store force. Therefore, when the sliding block 43 is released, the tension spring will use the stored force to drive the sliding block 43 to move upward and reset itself.

[0046] like Figure 15-16 As shown, the sliding device 5 includes a fixed cylinder 51, a guide block 52 and a third bolt 53. The fixed cylinder 51 is vertically arranged on one side of the guide block 52 and is slidably connected to the guide block 52.

[0047] like Figure 15-16 As shown, the third bolt 53 is located on one side of the fixed cylinder 51 and is threaded into a pre-set threaded through hole on the fixed cylinder 51. The guide block 52 is located at the position of the third bolt 53 and has multiple threaded holes along the length direction of the guide block 52.

[0048] like Figure 15-16 As shown, once the fixed cylinder 51 slides to the desired position, the third bolt 53 can be rotated forward until the end of the third bolt 53 is turned into the preset threaded hole on the guide block 52. At this time, the third bolt 53 can restrict the position of the fixed cylinder 51.

[0049] The movement process in this embodiment is as follows: After the guide block 52 is snapped onto the bed board of the hospital bed, the bottom end of the upright rod 11 can be vertically inserted into the inside of the fixing cylinder 51, and then the third bolt 53 is rotated in the opposite direction until the end of the third bolt 53 is turned out from the threaded hole on the guide block 52.

[0050] The fixing cylinder 51 can be slid along the length of the guide block 52 to adjust the relative position of the fixing cylinder 51 and the infusion stand 1 on the hospital bed. After the infusion stand 1 is adjusted to the required position, the third bolt 53 is rotated forward to turn the end of the third bolt 53 into the pre-set threaded hole on the guide block 52, thereby restricting the position of the fixing cylinder 51.

[0051] When it is necessary to move the IV stand 1, after the IV stand 1 is pulled out of the fixed cylinder 51, the pin 44 can be pulled out from the preset fixed hole 45 of the upright 11 and then the sliding block 43 can be pressed down until the caster 7 contacts the ground. Then the sliding block 43 can be stopped and the pin 44 can be inserted into the preset fixed hole 45 of the upright 11.

[0052] This restricts the position of the sliding block 43. Then, the first bolt 13 is rotated in the opposite direction and the connecting rod 12 is pulled out upwards to extend the total length of the infusion stand 1 until the height of the hook 2 is higher than the patient. Then, the connecting rod 12 is pulled out and the first bolt 13 is rotated in the forward direction.

[0053] Continue until the end of the first bolt 13 is turned into the pre-set threaded hole of the connecting rod 12, then rotate downward to open the hook 2. After opening the hook 2, the infusion bottle can be suspended on the hook 2.

[0054] Then rotate the handle 32 upwards until it is parallel to the sliding handle 31. You can then push the IV stand 1 with the handle. After the IV stand 1 is finished, pull the drawstring upwards and rotate the handle 32 downwards until the handle 32 is rotated 90 degrees and then release the drawstring 36.

[0055] Then, the connecting rod 12 is retracted into the upright rod 11, and the pin 44 is pulled out. After the spring 61 drives the sliding block 43 to move upward until the reset is completed, and the rotating rod 41 and the rotating rod 42 are retracted into the sliding groove 6, the pin 44 is reinserted into the preset fixing hole 45 of the upright rod 11. Then, the lower end of the upright rod 11 can be inserted into the fixing cylinder 51 to connect the infusion stand 1 to the hospital bed.

[0056] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
