Description
Technical Field
[0001] The utility model relates to the technical field of infusion equipment, in particular to a suspension rod for medical infusion. Background Art
[0002] There are various types of infusion stands currently used in hospitals, among which a common infusion stand structure is a suspension structure set on the ceiling of a ward or infusion room. Specifically, the suspension structure mainly includes a suspension rail and a suspension rod. The suspension rail is slidably connected to a sliding hook, the top of the suspension rod is connected to the sliding hook, and the bottom of the suspension rod is provided with a hook. When in use, the infusion bottle is directly hung or installed on the hook to complete the infusion operation. Although the existing suspension rod structure can suspend the infusion bottle and successfully complete the infusion operation, in actual use, in order to avoid the suspension rod being too long and occupying a large space in the room when no infusion is performed, the suspension rod and the sliding hook are usually set to a detachable connection form.
[0003] For example, the utility model patent with announcement number CN219983589U discloses a medical infusion hanging rod, in which a hook-shaped hook is arranged on the top outer wall of the upper hollow hanging tube, and a sliding sleeve is embedded on the inner side of the top of the upper hollow hanging tube, and the sliding sleeve is slidably connected to the sliding plate body, and an auxiliary support rod is arranged on the upper part of the sliding plate body, and a spring is arranged on the lower side of the sliding plate body, and the spring is sleeved on the sliding rod body, and the lower end of the spring is against the bottom inner wall of the sliding sleeve; when the spring is in a released state, the top of the auxiliary support rod is against the lower part of the end of the hook-shaped hook, and when the sliding plate body is pulled to slide downward, the spring is compressed and the top of the auxiliary support rod moves downward to form a gap with the end of the hook-shaped hook, at this time, the entire upper hollow hanging tube and the hook-shaped hook can be removed from the sliding hook on the top of the room through the formed gap, thereby preventing the hanging rod from being hung in the room all the time.
[0004] Although the above-mentioned hook-shaped hook and sliding plate structures can be used to disassemble the entire suspension rod from the sliding hook, in actual use, whether it is the installation or disassembly process, the user needs to pull the sliding plate downward to form a gap between the auxiliary support rod and the end of the hook-shaped hook, making the installation and disassembly process of the suspension rod more complicated. In particular, when installing the suspension rod, the user needs to pull the sliding plate downward on the one hand, and on the other hand, needs to observe the gap position between the auxiliary support rod and the end of the hook-shaped hook so that the sliding hook in the suspension guide rail can pass through the gap and enter the hook-shaped hook. Since the hook-shaped hook is located in a space with poor vision above the operator's head at this time, it is more difficult to push the sliding hook into the hook-shaped hook. Therefore, the suspension rod in the prior art cannot be easily and quickly disassembled. Utility Model Content
[0005] The utility model aims to provide a suspension rod for medical infusion, so as to solve the problem of inconvenient operation when the suspension rod for medical infusion is disassembled from a sliding hook in the prior art.
[0006] To solve the above problems, the utility model adopts the following technical solution: a suspension rod for medical infusion, comprising an upper hollow suspension tube and a hook-shaped hook fixedly connected to the top of the upper hollow suspension tube, a sliding plate body being slidably connected to the top of the upper hollow suspension tube, a rotating member rotatably connected to the sliding plate body and capable of rotating into the hook-shaped hook, an elastic reset member being connected between the rotating member and the sliding plate body, and when the elastic reset member is in a natural state, the rotating member contacts the end of the hook-shaped hook so that the limiting member cannot rotate outside the hook-shaped hook.
[0007] The principle and beneficial effects of the present scheme are as follows: in the present application, a sliding plate body is slidably connected to the top of the upper hollow suspension tube, a rotating member is rotatably connected to the sliding plate body, and an elastic reset member is connected between the rotating member and the sliding plate body. When the elastic reset member is in a natural state, the rotating member is in contact with the end of the hook-shaped hook, and the end of the hook-shaped hook has a fiber effect on the rotation of the rotating member, so that the rotating member cannot rotate outside the hook-shaped hook, so that after the hook-shaped hook is hung on the sliding hook in the prior art, the sliding hook is stably located in the hook-shaped hook, so that the entire suspension rod is stably connected to the sliding hook.
[0008] When the hanging rod needs to be removed, it is only necessary to use external force to pull the sliding plate body downward, and the rotating member moves downward with the sliding plate body, so that a gap is formed between the rotating member and the end of the hook-shaped hook for the sliding hook to pass through. The hanging rod can be separated from the sliding hook through the gap, and the hanging rod removal action can be completed conveniently.
[0009] At the same time, in the present application, when it is necessary to install the hanging rod from the disassembled state to the sliding hook in the prior art, the operator only needs to move the rotating member and the sliding plate body to the sliding hook position in the prior art, and then push the rotating member hard to approach and press against the sliding hook. Under the reaction force of the sliding hook, the sliding hook can push the rotating member to rotate into the hook-shaped hook, so that the sliding hook can easily and conveniently enter the hook-shaped hook and be limited. There is no need to pull the sliding plate body hard to complete the installation action as in the prior art, making the installation process of the entire hanging rod more convenient and labor-saving; and using the technical solution in the present application, when the operator installs the hanging rod to the sliding hook, even if the operator cannot clearly see the relative position relationship between the sliding hook and the sliding plate body, as long as the sliding hook can push the rotating member to rotate, the sliding hook can be quickly pushed and installed into the hook-shaped hook. Compared with the prior art that is affected by factors such as limited field of view when installing the hanging rod, the installation in the present application is less restricted, making the installation of the hanging rod less difficult and effectively improving the efficiency of the installation.
[0010] Preferably, as an improvement, a limiting member cooperating with the rotating member is provided on the sliding plate body, and when the rotating member contacts the end of the hook-shaped hook, the rotating member and the limiting member abut against each other.
[0011] In the present solution, a limit piece is provided to limit the rotation process of the rotating piece. In particular, when the hanging rod is removed from the sliding hook, the sliding plate body needs to be pulled to move the rotating piece away from the end of the hook-shaped hook. After the sliding hook is disengaged from the hook-shaped hook, the limiting effect of the limit piece is utilized during the resetting of the sliding plate body to avoid the rotating piece being located outside the end of the hook-shaped hook after resetting, thereby causing the need to reinstall the hanging rod later.
[0012] Preferably, as an improvement, the rotating member includes a rotating block rotatably connected to the top end of the sliding plate body, and the limiting member includes a limiting block fixedly connected to the top end of the sliding plate body.
[0013] In this solution, the rotating block has a simple structure and is easy to install. The limiting member is a limiting block, which can stably limit the rotation of the rotating block.
[0014] Preferably, as an improvement, a guide portion is provided on the end of the hook-shaped hook and / or the side of the limit block end facing away from the hook-shaped hook.
[0015] In this solution, by providing a guide portion at the end of the hook-shaped hook and / or the side of the limit block facing away from the hook-shaped hook, the guide portion can provide guidance for the process of the sliding hook being pushed into the hook-shaped hook during the installation of the suspension rod, thereby making the installation process of the sliding hook more convenient and efficient.
[0016] Preferably, as an improvement, the guide portion includes a guide slope provided on the end of the hook-shaped hook and / or the limiting block.
[0017] In this solution, a guiding slope is used as the guiding part. The guiding slope has a simple structure, is easy to process, and can achieve a good guiding effect.
[0018] Preferably, as an improvement, the outer wall of the upper hollow suspension tube is provided with a chamfer that matches the guiding inclined surface on the limit block.
[0019] In this solution, by arranging a chamfer on the outer wall of the upper hollow suspension tube and utilizing the guiding function of the chamfer, the sliding hook can more conveniently enter the hook-shaped hook.
[0020] Preferably, as an improvement, the end of the hook-shaped hook is bent inwardly of the hook-shaped hook.
[0021] In this solution, the end of the hook-shaped hook is tilted inwardly of the hook-shaped hook, and the bent structure of the end of the hook-shaped hook can guide the installation of the sliding hook, further improving the convenience during the installation process.
[0022] Preferably, as an improvement, the elastic return member comprises a tension spring, one end of the tension spring is fixedly connected to the limiting block, and the other end of the tension spring is fixedly connected to the side wall of the rotating block.
[0023] In this solution, a tension spring is used as an elastic reset member. The tension of the tension spring is stable, and when the sliding hook is pushed into the hook-shaped hook, it can easily push the tension spring to deform and rotate the rotating block to an open state, so that the sliding hook can easily enter the hook-shaped hook and be limited.
[0024] Preferably, as an improvement, the elastic reset member includes a torsion spring connected between the rotating block and the sliding plate body.
[0025] In this solution, a torsion spring is used as an elastic reset member, the torsion force of the torsion spring is stable and the installation of the torsion spring is very convenient.
[0026] Preferably, as an improvement, a mating groove for mating with the rotating member is provided on a side of the end of the hook-shaped hook facing the inside of the hook-shaped hook.
[0027] In this solution, a matching groove is provided on the side of the hook-shaped hook end facing the inside of the hook-shaped hook. The matching groove can be used to limit the rotation of the rotating part until it connects with the inner side of the hook-shaped hook end, so that a stable matching relationship is formed between the rotating part and the hook-shaped hook end, avoiding the rotating part from shaking randomly during use, etc., which may cause the sliding hook to fall off accidentally.

[0032] The following is further described in detail through specific implementation methods:
[0033] The figure marks in the drawings of the specification include: upper hollow suspension tube 1, chamfer 101, hook-shaped hook 2, second guide slope 201, matching groove 202, sliding hook 3, sliding plate body 4, sliding rod 5, compression spring 6, fixed plate 7, rotating block 8, limit block 9, accommodating groove 901, first guide slope 902, tension spring 10.
[0034] Embodiment 1
[0035] This embodiment is as shown in the attached Figure 1 and Figure 2 As shown: A suspension rod for medical infusion, including an upper hollow suspension tube 1 and a hook-shaped hook 2 welded to the top of the upper hollow suspension tube 1, and a certain distance between the end of the hook-shaped hook 2 and the upper hollow suspension tube 1 in the vertical direction, so that the sliding hook 3 in the prior art can enter the hook-shaped hook 2 horizontally from the outside of the hook-shaped hook 2.
[0036] Combination Figure 1 and Figure 2 , the upper hollow suspension tube 1 is vertically slidably connected to the sliding plate body 4 near the top, the bottom end of the sliding plate body 4 is integrally formed with a vertically arranged sliding rod 5, a compression spring 6 is sleeved on the sliding rod 5, the top of the compression spring 6 is against the bottom surface of the sliding plate body 4, and a fixing plate 7 is fixedly connected to the upper hollow suspension rod by screws, the bottom end of the compression spring 6 is in contact with the top surface of the fixing plate 7, and a sliding hole is opened in the center of the fixing plate 7, and the bottom end of the sliding rod 5 passes through the sliding hole downward and slides with the fixing plate 7. When the sliding rod 5 is pulled downward by external force, the sliding rod 5 can pull the sliding plate body 4 to slide downward, at this time, the compression spring 6 is compressed and stored, and when the downward pulling force on the sliding rod 5 disappears, under the elastic force of the compression spring 6, the sliding plate body 4 slides upward and automatically resets.
[0037] like Figure 2 As shown, the top surface of the sliding plate body 4 is rotatably connected to a rotating member that can rotate toward the hook-shaped hook 2 through a pin shaft, that is, the rotating member can rotate along Figure 1 The rotating member rotates counterclockwise, and an elastic reset member is connected between the rotating member and the sliding plate body 4. When the elastic reset member is in a natural state, the rotating member contacts the end of the hook-shaped hook 2. At this time, under the limiting blocking effect of the end of the hook-shaped hook 2, the rotating member cannot rotate clockwise and rotates outside the hook-shaped hook 2.
[0038] Specifically, the rotating member is a rotating block 8 rotatably connected to the top of the sliding plate body 4 through a pin shaft. The top surface of the sliding plate body 4 is provided with a limiter that cooperates with the rotating block 8. When the rotating block 8 contacts the end of the hook-shaped hook 2, the rotating block 8 and the limiter abut against each other. Specifically, the limiter is a limiter 9 fixedly connected to the top surface of the sliding plate body 4 by a screw. The limiter 9 is located on the right side of the rotating block 8. The blocking limit of the limiter 9 can avoid Figure 1The rotating rod in the hook-shaped hook 2 rotates clockwise to the outside of the hook-shaped hook 2 and cannot effectively limit the sliding hook 3 in the hook-shaped hook 2.
[0039] In this embodiment, the elastic return member is a tension spring 10, and a transversely arranged accommodating groove 901 is opened on the left side surface of the limit block 9. The tension spring 10 is located in the accommodating groove 901. The left end of the tension spring 10 is hung on the right side wall of the rotating block 8, and the right end of the tension spring 10 is hung on the limit block 9. Since the hanging installation of the tension spring 10 belongs to the conventional technical means in this field, the specific connection method of the tension spring 10, the rotating block 8 and the limit block 9 will not be repeated here.
[0040] At the same time, in order to make the sliding hook 3 be pushed into the hook-shaped hook 2 more conveniently, quickly and accurately, a guide portion is provided at the end of the hook-shaped hook 2 and / or the side of the stop block 9 facing away from the hook-shaped hook 2, and the guide portion includes a guide slope provided on the end of the hook-shaped hook 2 and / or the stop block 9. In this embodiment, a first guide slope 902 is provided on the right side surface of the stop block 9, and a second guide slope 201 is provided on the right side surface of the end of the hook-shaped hook 2. The first guide slope 902 and the second guide slope 201 can both guide the sliding hook 3 to be pushed into the hook-shaped hook 2, and a chamfer 101 matching the first guide slope 902 is provided on the outer wall of the upper hollow suspension tube 1, and the chamfer 101 plays an auxiliary guiding role in pushing the sliding hook 3 into the hook-shaped hook 2.
[0041] The specific implementation process is as follows:
[0042] When the sliding hook 3 in the prior art needs to be installed on the hook-shaped hook 2, the operator only needs to move the suspension rod upward to the sliding hook 3 so that the rotating rod block faces the sliding hook 3, and then move the upper hollow suspension tube 1 horizontally to make the sliding hook 3 contact and press against the rotating block 8. Under the action of the sliding hook 3, the rotating block 8 rotates relative to the sliding plate body 4 to form a gap between the rotating block 8 and the end of the hook-shaped hook 2. The sliding hook 3 passes through the gap to make the sliding hook 3 slide into the hook-shaped hook 2 and be limited. After the sliding hook 3 is pushed into the hook-shaped hook 2, the rotating block 8 is reset under the elastic force of the tension spring 10, so that the rotating block 8 rotates to a state of contact with the end of the hook-shaped hook 2. At this time, the sliding hook 3 is stably limited in the hook-shaped hook 2.
[0043] When it is necessary to remove the hanging rod from the sliding hook 3, first use external force to pull the sliding rod 5 downward, the sliding rod 5 drives the sliding plate body 4 and the rotating block 8 to move downward relative to the upper hollow hanging tube 1, and the rotating block 8 moves downward relative to the end of the hook-shaped hook 2. When the top of the rotating block 8 is separated from the end of the hook-shaped hook 2 and slides into the upper hollow hanging tube 1, there is a gap between the top of the rotating block 8 and the end of the hook-shaped hook 2. At this time, the hanging rod is moved horizontally to separate the entire hanging rod from the sliding hook 3, thereby realizing the removal of the hanging rod and avoiding the hanging rod being hung on the sliding hook 3 and occupying space in the ward.
[0044] Embodiment 2
[0045] The difference between the second embodiment and the first embodiment is that: in order to make it more convenient and smooth when the sliding hook 3 is pushed into the hook-shaped hook 2, as shown in FIG. Figure 3 As shown, in this embodiment, the end of the hook-shaped hook 2 is bent inwardly of the hook-shaped hook 2, and the bending shape of the end of the hook-shaped hook 2 is used to guide the pushing process of the sliding hook 3.
[0046] Embodiment 3
[0047] The difference between Example 3 and Example 1 is that the elastic return member in Example 1 is a tension spring 10, while in this embodiment, in order to simplify the structure, the elastic return member in this embodiment is a torsion spring connected between the rotating block 8 and the sliding plate body 4, and the torsion spring is sleeved on the rotating shaft forming a rotating connection between the rotating block 8 and the sliding plate body 4.
[0048] Embodiment 4
[0049] The difference between the fourth embodiment and the first embodiment is that: Figure 4 As shown, in this embodiment, a matching groove 202 matching with the rotating block 8 is provided at the side of the end of the hook-shaped hook 2 facing the inside of the hook-shaped hook 2. When the rotating block 8 is rotated and reset to contact with the limit block 9, the top of the rotating block 8 is located in the matching groove 202. The matching groove 202 is used to limit and stabilize the top of the rotating block 8, so that the rotating block 8 will not slide easily, etc., so that the rotating block 8 can stabilize and limit the sliding hook 3 in the hook-shaped hook 2, thereby improving the stability of the entire suspension rod.
