Description

Technical Field

[0001] The invention relates to the technical field of medical treatment, in particular to a multifunctional infusion stand. Background Art

[0002] An infusion stand is a medical device used to hang infusion bottles or infusion bags so that the infusion bottles or infusion bags are at a suitable height to facilitate the smooth flow of liquid into the patient's body. In order to improve stability, the infusion stand is provided with four supporting legs at the bottom. The existing infusion stand has a relatively single function and only serves as a simple hanging effect of infusion bottles. When the patient wants to go for a walk outdoors during the infusion process, the patient needs to hold the infusion stand to move it. Some patients with limited mobility will use the infusion stand as a support. When walking on an uneven road surface, some of the supporting legs will not be able to contact the ground, and thus cannot provide stable support for the infusion stand. When the user applies downward pressure on the infusion stand and provides support for himself, the suspended supporting legs will tilt downward, causing the infusion stand to tilt as a whole, thereby failing to provide stable support to the user.

DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1

[0032] Reference Figure 2-Figure 7 , which is the first embodiment of the present invention, provides a multifunctional infusion stand. The multifunctional infusion stand includes an infusion stand assembly 100 and a base 101.

[0033] The base 101 is used to install and fix the support assembly 200 .

[0034] The support assembly 200 is arranged in the base 101, and includes a positioning sleeve 201a, a support leg 201b, a rotating frame 201c, a guide shaft 201d, a fixed block 201e, a support ring 201f, a rotating rod 201g and a first spring 201h. The positioning sleeve 201a is fixed to the bottom of the base 101, the support leg 201b is inserted into the positioning sleeve 201a, the rotating frame 201c is rotatably connected to the base 101 and sleeved on the outside of the support leg 201b, and the guide shaft 201d is fixed to the rotating rod 201g. In the movable frame 201c, a guide groove 201b-1 is provided on the support leg 201b, the guide shaft 201d slides in the guide groove 201b-1, the fixed block 201e is fixed on one side of the rotating frame 201c, the support ring 201f is fixed in the fixed block 201e, the rotating rod 201g is movably connected to the outside of the support ring 201f and fits with the rotating frame 201c, and the two ends of the first spring 201h are respectively fixed to the rotating rod 201g and the fixed block 201e, and are sleeved on the outside of the support ring 201f.

[0035] There are four groups of support components 200, which are respectively located at the four corners inside the base 101. The rotating frame 201c is rotatably connected to the base 101 through a bearing. The guide groove 201b-1 is inclined, and the support ring 201f is used to rotate the rotating rod 201g.

[0036] When the rotating rod 201g rotates, it will squeeze the first spring 201h. At this time, if the supporting leg 201b is already in contact with the ground, the rotating rod 201g will compress the first spring 201h without pushing the fixed block 201e and the rotating frame 201c to rotate. The positioning sleeve 201a is used to position the supporting leg 201b to prevent the supporting leg 201b from tilting.

[0037] When the support leg 201b is not in contact with the ground and is in a suspended state, the rotating rod 201g will push the fixed block 201e and the rotating frame 201c to rotate through the first spring 201h, so that the rotating frame 201c drives the guide shaft 201d to slide in the guide groove 201b-1. Through the cooperation of the two, the support leg 201b can be driven to move downward, so that the suspended support leg 201b can contact the ground, thereby providing stable support for the infusion stand assembly 100, and preventing the infusion stand assembly 100 from tilting due to unstable support when the user applies downward pressure on the infusion stand assembly 100.

[0038] The pushing assembly 300 is arranged in the base 101, and includes a rotating sleeve 301a, a pressing plate 301b, a connecting rod 301c, a sliding shaft 301d, a rotating sleeve 301e, a movable column 301f, a fixed shaft 301g, a force plate 301h and a torsion spring 301i. The rotating sleeve 301a is rotatably connected to the base 101, the pressing plate 301b is fixed to the outside of the rotating sleeve 301a, the connecting rod 301c is located at the top of the rotating rod 201g, the sliding shaft 301d is fixed to the bottom of the connecting rod 301c, and the rotating rod 201g is provided with a sliding groove 201g-1, and the sliding shaft 301d is fixed to the bottom of the connecting rod 301c. The shaft 301d slides in the slide groove 201g-1, the rotating sleeve 301e is rotatably connected to the base 101 and is located on the inner side of the rotating sleeve 301a, the movable column 301f is inserted into the rotating sleeve 301e, the fixed shaft 301g is fixed in the rotating sleeve 301e, and a spiral groove 301f-1 is provided on the movable column 301f. The fixed shaft 301g slides in the spiral groove 301f-1, the force plate 301h is fixed to the bottom of the movable column 301f, and the two ends of the torsion spring 301i are respectively fixed to the rotating sleeve 301e and the rotating sleeve 301a, and are sleeved on the outer side of the rotating sleeve 301e.

[0039] The number of the pushing components 300 corresponds to the supporting components 200. When the rotating sleeve 301a rotates, it will drive the extrusion plate 301b to push the connecting rod 301c to move. The connecting rod 301c drives the rotating rod 201g to rotate through the cooperation between the sliding shaft 301d and the slide groove 201g-1, so that the fixed block 201e and the rotating frame 201c can be pushed to rotate through the rotating rod 201g.

[0040] The force-bearing plate 301h is hollowed out to reduce its weight. In the initial state, the force-bearing plate 301h will contact the ground before the supporting leg 201b. When the force-bearing plate 301h contacts the ground, as the base 101 moves downward, the force-bearing plate 301h will be subjected to the reverse thrust of the ground and drive the movable column 301f to move upward. When the movable column 301f moves, the fixed shaft 301g will slide in the spiral groove 301f-1. Through the cooperation of the two, the rotating sleeve 301e can be driven to rotate. When the rotating sleeve 301e rotates, the torsion spring 301i will be tightened. When the supporting leg 201b contacts the ground and the movable column 301f stops moving, the tightened torsion spring 301i will drive the rotating sleeve 301a to rotate.

[0041] The elastic force of the torsion spring 301i is greater than the sum of the elastic forces of the first spring 201h, the third spring 202e and the seventh spring 305c. Therefore, the elastic force of the torsion spring 301i can move the supporting leg 201b downward.

[0042] Example 2

[0043] Reference Figure 2-Figure 8 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0044] Specifically, a positioning rod 202a is fixed to the top wall of the base 101, a slot 201b-2 is provided in the supporting leg 201b, the positioning rod 202a is movably connected to the slot 201b-2, a chamber 202a-1 is provided in the positioning rod 202a, a supporting frame 202b is provided in the chamber 202a-1, a clamping block 202c is provided in the supporting frame 202b, a clamping slot 201b-3 is provided in the supporting leg 201b, a second spring 202d is fixed to one side of the clamping block 202c, one end of the second spring 202d is fixed to the inner wall of the supporting frame 202b, a third spring 202e is fixed to the bottom of the positioning rod 202a, and the bottom end of the third spring 202e is fixed to the inner wall of the chamber 202a-1.

[0045] The positioning rod 202a is rectangular. Through the cooperation between the positioning rod 202a and the slot 201b-2, the support leg 201b can be limited so that it will not rotate during movement. One side of the block 202c is inclined, and there are multiple slots 201b-3, which are evenly distributed in a straight line in the support leg 201b.

[0046] When the support leg 201b moves downward, the support frame 202b will drive the block 202c to move into the slot 201b-3, and make the block 202c engage with the slot 201b-3. Through the cooperation of the two, the support leg 201b can be limited in one direction, so that the support leg 201b can move downward but not upward, and then the support leg 201b can contact the ground and will not move upward when it is pushed in the opposite direction by the ground, thereby providing stable support for the infusion stand assembly 100.

[0047] The second spring 202d is used to apply a thrust to the block 202c, so that the block 202c and the slot 201b-3 are more tightly engaged. When the block 202c is separated from the slot 201b-3, the third spring 202e can drive the support leg 201b to reset upward, so that the support leg 201b recovers its initial height, thereby avoiding the situation where the height of the support leg 201b is difficult to change during the next use, thereby causing the infusion stand assembly 100 to tilt.

[0048] Specifically, a force block 203a is fixed on the top of the support frame 202b, one side of the force block 203a is inclined, a push rod 203b is arranged above the force block 203a, a push plate 203c is inserted into the positioning rod 202a, one side of the push plate 203c is inclined, a support rod 203d is fixed to one side of the movable column 301f, a support column 203e is fixed on the top of the support rod 203d, an extrusion block 203f is fixed on the top of the support column 203e, and both ends of the extrusion block 203f are inclined.

[0049] The support column 203e is movably connected to the base 101. When the movable column 301f moves upward, the inclined surface of the extrusion block 203f is driven to contact the push plate 203c through the support rod 203d and the support column 203e, and the push plate 203c is pushed to move, so that the inclined surface of the end of the push plate 203c presses the push rod 203b downward, and the inclined surface of the force block 203a is squeezed by the push rod 203b, thereby driving the support frame 202b to move, and then the support frame 202b can drive the clamping block 202c to engage with the clamping slot 201b-3.

[0050] Specifically, a fourth spring 202b-1 is fixed to one side of the support frame 202b, and one end of the fourth spring 202b-1 is fixed to the inner wall of the chamber 202a-1.

[0051] When the movable column 301f moves downward and the extrusion block 203f is separated from the push plate 203c, the fourth spring 202b-1 can apply a pulling force to the support frame 202b to reset it and separate the clamping block 202c from the clamping slot 201b-3.

[0052] Specifically, a support sleeve 302a is provided on one side of the rotating sleeve 301a, a limiting block 302b is provided in the support sleeve 302a, a limiting groove 301a-1 is provided on the rotating sleeve 301a, the limiting block 302b is engaged with the limiting groove 301a-1, a fifth spring 302c is fixed on one side of the limiting block 302b, and one end of the fifth spring 302c is fixed to the inner wall of the support sleeve 302a.

[0053] The support sleeve 302a is fixed to the inner bottom wall of the base 101 through a support plate, and one side of the limit block 302b is inclined. There are multiple limit grooves 301a-1, which are evenly distributed in a ring shape on the outside of the rotating sleeve 301a. The limit block 302b cooperates with the limit groove 301a-1 to lock the rotating sleeve 301a so that the rotating sleeve 301a will not rotate when subjected to the torsion force of the torsion spring 301i. Only when the support leg 201b is in contact with the ground can the torsion spring 301i drive the rotating sleeve 301a to rotate, thereby preventing the support leg 201b from moving downward when not in contact with the ground, thereby causing the height of the infusion stand assembly 100 to increase.

[0054] The fifth spring 302c applies a thrust to the limit block 302b, so that the limit block 302b can always engage with the limit groove 301a-1. Through the setting of the inclined surface of the limit block 302b, the rotating sleeve 301a will be restricted only when the movable column 301f moves upward and the torsion spring 301i is tightened. When the movable column 301f moves downward, the rotating sleeve 301a will not be locked, so that the rotating sleeve 301a can follow the downward movement of the movable column 301f and rotate to reset.

[0055] Specifically, a connecting plate 303a is fixed to one side of the top of the movable column 301f, an extrusion rod 303b is fixed to the bottom of the connecting plate 303a, one side of the bottom end of the extrusion rod 303b is inclined, and a force groove 302b-1 corresponding to the extrusion rod 303b is opened on the limit block 302b.

[0056] When the movable column 301f moves upward, it will drive the connecting plate 303a and the extrusion rod 303b to move upward, and make the inclined surface of the bottom end of the extrusion rod 303b approach the force groove 302b-1. When the supporting leg 201b contacts the ground, the inclined surface of the bottom end of the extrusion rod 303b will squeeze the inner wall of the force groove 302b-1, and the cooperation of the two will drive the limit block 302b to move, so that the limit block 302b can be separated from the limit groove 301a-1, thereby releasing the restriction on the rotating sleeve 301a.

[0057] Example 3

[0058] Reference Figure 1-Figure 8 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0059] Specifically, a sixth spring 304 is fixed to the top of the movable column 301 f , and the top of the sixth spring 304 is fixed to the inner top wall of the base 101 .

[0060] The sixth spring 304 applies a downward thrust to the movable column 301f, so that the base 101 moves upward and the support leg 201b is separated from the ground, and the movable column 301f can move downward. When the base 101 drives the support leg 201b downward to contact the ground, the force plate 301h will contact the ground in advance. At this time, the weight of the base 101 and the internal structure can move the force plate 301h upward and squeeze the sixth spring 304 and the torsion spring 301i, without the user applying additional downward pressure to the infusion stand assembly 100.

[0061] Specifically, a positioning block 305a is fixed at the bottom of the connecting rod 301c, and a positioning column 305b is fixed on the inner wall of the base 101. The positioning column 305b is movably connected to the positioning block 305a.

[0062] The positioning block 305a cooperates with the positioning column 305b to support and position the connecting rod 301c to prevent it from tilting during movement.

[0063] Specifically, a seventh spring 305c is sleeved on the outer side of the positioning column 305b, and two ends of the seventh spring 305c are respectively fixed to the positioning block 305a and the inner wall of the base 101.

[0064] The seventh spring 305c applies a thrust to the positioning block 305a, so that the positioning block 305a drives the connecting rod 301c to return to its original position.

[0065] Specifically, the infusion stand assembly 100 also includes a fixing sleeve 102, which is fixed to the top of the base 101, a stabilizing rod 103 is inserted into the fixing sleeve 102, a handle 104 is fixed on the stabilizing rod 103, a hook 105 is fixed on the top of the stabilizing rod 103, a positioning ring 106 is fixed on the stabilizing rod 103, and the positioning ring 106 is located below the hook 105.

[0066] The setting of the handle 104 can facilitate the patient to pick up the stabilizing rod 103. At the same time, the handle 104 can provide support for the patient during walking. The hook 105 is used to hang the infusion bottle. When hanging the infusion bottle, the infusion bottle is placed in the positioning ring 106, and the infusion bottle is positioned by the positioning ring 106 to prevent the infusion bottle from shaking when the patient is walking.

[0067] The stabilizing rod 103 can move up and down in the fixing sleeve 102 and is equipped with a locking mechanism, which can adjust the height of the stabilizing rod 103 to adapt to users of different heights and can hang the infusion bottle at different heights. This is the prior art and will not be elaborated in detail in this solution.

[0068] In summary, the multifunctional infusion stand of the present invention has the following advantages:

[0069] 1. When the road surface is uneven, the suspended support leg 201b can automatically move downward and contact the ground, thereby providing stable support for the infusion stand assembly 100;

[0070] Second, when the infusion stand assembly 100 is lifted upward, the support leg 201b can automatically reset to the initial state, thereby avoiding the situation in which the infusion stand assembly 100 tilts due to the different heights of the support leg 201b during the next use;

[0071] 3. When the support leg 201b is extended and moved up and down, the user does not need to perform any additional operations, and only needs to use the infusion stand assembly 100 to support itself normally, thereby improving the convenience of use;

[0072] Fourth, when the force-bearing plate 301h contacts the ground, the sixth spring 304 can reduce the impact force generated when the force-bearing plate 301h contacts the ground.

[0073] During use, when the user holds the handle 104 and drives the base 101 to contact the ground, the force plate 301h will first contact the ground. As the base 101 moves downward, the force plate 301h will be subjected to the reverse thrust of the ground and drive the movable column 301f to move upward. When the movable column 301f moves, the fixed shaft 301g will slide in the spiral groove 301f-1. Through the cooperation of the two, the rotating sleeve 301e can be driven to rotate. When the rotating sleeve 301e rotates, the torsion spring 301i will be tightened. When the supporting leg 201b contacts the ground and the movable column 301f stops moving, the tightened torsion spring 301i will drive the rotating sleeve 301a to rotate.

[0074] When the rotating sleeve 301a rotates, it drives the extrusion plate 301b to push the connecting rod 301c to move, and the connecting rod 301c drives the rotating rod 201g to rotate through the cooperation between the sliding shaft 301d and the sliding groove 201g-1.

[0075] When the rotating rod 201g rotates, it will squeeze the first spring 201h. At this time, if the supporting leg 201b has been in contact with the ground, the rotating rod 201g will compress the first spring 201h without pushing the fixed block 201e and the rotating frame 201c to rotate.

[0076] When the support leg 201b is not in contact with the ground and is in a suspended state, the rotating rod 201g will push the fixed block 201e and the rotating frame 201c to rotate through the first spring 201h, so that the rotating frame 201c drives the guide shaft 201d to slide in the guide groove 201b-1. Through the cooperation of the two, the support leg 201b can be driven to move downward, so that the suspended support leg 201b can contact the ground, thereby providing stable support for the infusion stand assembly 100, and preventing the infusion stand assembly 100 from tilting due to unstable support when the user applies downward pressure on the infusion stand assembly 100.

[0077] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
