Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary equipment technology, and in particular to a detachable medical hook. Background Technology

[0002] During dentistry, such as when extracting impacted wisdom teeth, the procedure is quite invasive. To avoid inflammation and infection, intravenous infusion is often used to prevent infection and reduce swelling. Currently, IV stands are commonly placed next to the dental chair to suspend the IV bag. However, this placement encroaches on the dentist's working space, and the dentist may bump into the stand during movement, posing a risk of it tipping over. After treatment, the IV stand needs to be removed and stored (especially in rooms with limited space, requiring relocation to another room). It must then be retrieved and placed back next to the dental chair for the next use, causing inconvenience. Utility Model Content

[0003] The purpose of this invention is to provide a detachable medical hook to solve the problem in the prior art where dentists need to move the infusion stand back and forth when administering intravenous infusions to patients, which is inconvenient.

[0004] To achieve the above objectives, this application provides a detachable medical hook, comprising:

[0005] A snap-fit ​​connector for mounting on a columnar structural member, the snap-fit ​​connector being detachably connected to the columnar structural member;

[0006] The first hook is fixedly connected to the bottom of the snap-fit ​​component;

[0007] The second hook body is at least partially housed within the first hook body. The second hook body is rotatably mounted on the bottom of the snap-fit ​​component. Rotating the second hook body causes it to move out of the first hook body.

[0008] In some embodiments of this application, the detachable medical hook has a first direction perpendicular to the plane containing the first hook body;

[0009] The second hook body is provided in two parts, and the two second hook bodies are provided on both sides of the first hook body along the first direction.

[0010] In some embodiments of this application, the detachable medical hook further includes a connecting part, one end of which is connected to the snap-fit ​​member, and the other end of which is fixedly connected to the first hook body;

[0011] Both second hooks are rotatably mounted on the end of the connecting part away from the snap-fit ​​component.

[0012] In some embodiments of this application, the first hook body is provided with receiving grooves on both sides along the first direction, and the projection of the receiving groove along the first direction matches the projection of the second hook body along the first direction.

[0013] The second hook is at least partially housed in the receiving groove, so that the second hook is in the retracted position. The second hook is rotated so that it moves outward from the receiving groove, and the second hook is in the unfolded position.

[0014] In some embodiments of this application, the second hook body includes a vertical part and a hook part connected to the bottom of the vertical part, the vertical part extending vertically and being rotatably connected to the connecting part;

[0015] An adjusting bolt is threaded onto the connecting part, and a sliding rod is coaxially connected to the bottom of the adjusting bolt. The sliding rod is coaxially arranged with the vertical part, and the sliding rod is axially movable and connected to the vertical part.

[0016] In some embodiments of this application, the hook portion is connected to an extension portion extending vertically, the vertical portion is coaxially provided with a downwardly penetrating receiving cavity, the extension portion is coaxially provided in the receiving cavity, and the extension portion is axially movable and connected to the receiving cavity.

[0017] In some embodiments of this application, the extension is spaced apart from the inner wall of the accommodating cavity, an internally threaded cylinder is rotatably mounted on the bottom wall of the vertical part, and a threaded portion is provided on the outer periphery of the extension to thread with the internally threaded cylinder.

[0018] The extension is provided with a guide hole extending vertically, and the accommodating cavity is provided with a guide rod that is slidably assembled with the guide hole. The guide rod and the guide hole are used to restrict the circumferential rotation of the extension relative to the vertical part. Rotating the internal threaded cylinder causes the extension to move axially within the accommodating cavity.

[0019] In some embodiments of this application, the snap-fit ​​component includes a first snap-fit ​​portion and a second snap-fit ​​portion, wherein the first snap-fit ​​portion is provided with a first arc-shaped groove on the side facing the second snap-fit ​​portion, and the second snap-fit ​​portion is provided with a second arc-shaped groove on the side facing the first snap-fit ​​portion.

[0020] The first and second snap-fit ​​portions are connected to a driving member. The driving member drives the first and second snap-fit ​​portions to move closer to each other along the radial direction of the columnar structure. The first and second arc-shaped grooves both press against the outer wall of the columnar structure, so that the snap-fit ​​portion snaps into the columnar structure.

[0021] Alternatively, the driving member can drive the first and second locking portions to move away radially from the columnar structure, thereby removing the locking member from the columnar structure.

[0022] In some embodiments of this application, the driving member includes two snap-fit ​​bolts, both of which are threadedly fitted to the first snap-fit ​​portion and the second snap-fit ​​portion. By rotating the two snap-fit ​​bolts, the first snap-fit ​​portion and the second snap-fit ​​portion are driven to move radially along the columnar structural member.

[0023] In some embodiments of this application, the inner wall of the first arc-shaped groove is provided with a first rubber layer, and the inner wall of the second arc-shaped groove is provided with a second rubber layer.

[0024] Compared with the prior art, the detachable medical hook of this utility model has the following advantages: This solution directly installs the first hook and the second hook for suspending infusion bottles (bags) on the columnar structure (lamp arm) of the dental chair by setting a snap-fit ​​connector, eliminating the need for an additional infusion stand next to the dental chair. Moreover, since the first hook and the second hook are directly suspended on the columnar structure (lamp arm) of the dental chair, they do not encroach on the doctor's operating space next to the dental chair. At the same time, after use, the snap-fit ​​connector can be directly removed from the column and the second hook can be folded up, so that the hook maintains a small size, making it easy to store. It can be placed in a drawer in the treatment room or any other relatively small space, and can be quickly taken out and used next time. Attached Figure Description

[0039] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0040] In the description of this utility model, it should be understood that the terms "upper," "lower," "left," "right," "front," "rear," "top," and "bottom," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as an obstruction of this utility model. It should be understood that the terms "first," "second," etc., are used in this utility model to describe various information, but this information should not be limited to these terms; these terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this utility model, "first" information can also be called "second" information, and similarly, "second" information can also be called "first" information.

[0041] like Figures 1-8 As shown, this application embodiment proposes a detachable medical hook, including a snap-fit ​​component 1, a first hook body 2, and a second hook body 3; the snap-fit ​​component 1 is used to install on a columnar structural member 8, such as... Figure 8As shown, this is a dental chair that is adapted to use with the detachable medical hook in this solution. A light is installed on the dental chair, and the light is mounted on the dental chair via a light arm. The snap-fit ​​component 1 in this solution is installed on the light arm (i.e.,...) Figure 8 On the columnar structural member 8 shown, since the lamp arm is located above the dental chair, it does not encroach on the space next to the dental chair, thus ensuring that the dentist's operating space is not affected. At the same time, its higher position reduces the probability of accidental contact by the dentist. A first hook 2 is fixedly connected to the bottom of the snap-fit ​​member 1, and a second hook 3 is rotatably mounted on the bottom of the snap-fit ​​member 1. When not in use and stored, at least a portion of the second hook 3 is accommodated within the first hook 2 (e.g., ...). Figure 1 As shown), this reduces its size, allowing it to be placed in a drawer or any small space in the treatment room without taking up much space. When needed, it can be quickly taken out and used. When in use, the second hook 3 is rotated and removed from the first hook 2, thus enabling it to be used for suspending the infusion bottle (bag).

[0042] In this solution, a fixed first hook 2 and a rotatably mounted second hook 3 are provided at the bottom of the snap-fit ​​connector 1. When the patient requires a large infusion volume (with multiple infusion bottles or bags), both the first hook 2 and the second hook 3 can be used to suspend the infusion bottles (bags). That is, the doctor can suspend all the infusion bottles (bags) that need to be infused on the patient on the first hook 2 or the second hook 3. When one infusion bottle (bag) is used up, the needle is inserted into the next infusion bottle (bag) to continue the infusion. The used infusion bottle (bag) does not need to be removed. After all the infusions are completed, the doctor can directly observe the infusion bottles (bags) hanging on the hooks to clearly know the amount of infusion the patient has completed, avoiding omissions or duplicate infusions.

[0043] Alternatively, the first hook 2 can be used to hang the infusion bottle (bag), while the second hook 3 can be used to hang other items, such as the patient's treatment information card or register (used to record the type and quantity of infusion required by the patient). When each bottle of infusion is completed, the doctor can mark it on the register, which helps the doctor to clearly understand the patient's infusion status (avoiding duplicate infusions or missed infusions).

[0044] After the infusion is completed, the doctor retracts the second hook 3 and removes the clip 1 from the columnar structure 8. Retracting the second hook 3 further reduces the size of the medical hook, making it easy to store in a drawer or other small space in the treatment room. Even if the treatment room space is limited, it can be easily stored (without needing to be moved outside the treatment room for storage). Alternatively, depending on the usage needs, it is not necessary to remove the clip 1 from the columnar structure 8; simply retracting the second hook 3 is sufficient. Since the second hook 3 is in the retracted state, the medical hook will not take up much space above the dental chair even when suspended on the columnar structure 8 (it will not hinder the normal use of the dental chair).

[0045] In some embodiments of this application, such as Figure 1 , Figure 2 As shown, the detachable medical hook has a first direction X perpendicular to the plane of the first hook body 2. Two second hook bodies 3 are provided, located on either side of the first hook body 2 along the first direction X. At least a portion of each second hook body 3 is housed within the first hook body 2 (the presence of two second hook bodies 3 allows the medical hook to hang more items, further expanding its functionality). When in use, depending on the amount of intravenous fluid administered to the patient, one or both second hook bodies 3 can be selectively extended from the first hook body 2 to hang a greater number of infusion bottles (bags), treatment information cards, or registers. When not in use, both second hook bodies 3 can be retracted, with at least a portion housed within the first hook body 2, reducing the overall volume of the medical hook and facilitating its storage in any relatively small space, even in a treatment room with limited space.

[0046] In some embodiments of this application, such as Figure 2 As shown, the detachable medical hook also includes a connecting part 123. One end of the connecting part 123 is fixedly connected to the snap-fit ​​1, and the other end of the connecting part 123 is fixedly connected to the first hook body 2. Two second hook bodies 3 are rotatably installed on the end of the connecting part 123 away from the snap-fit ​​1.

[0047] In some embodiments of this application, such as Figure 2 , Figure 3 As shown, receiving grooves 21 are respectively provided on both sides of the first hook body 2 along the first direction X. The projection of the receiving groove 21 along the first direction X matches the projection of the second hook body 3 along the first direction X (the projection contour of the receiving groove 21 in the first direction X is greater than or equal to the projection contour of the second hook body 3 in the first direction X, so that the second hook body 3 can be accommodated in the receiving groove 21); Figure 1 As shown, when the second hook 3 is housed in the receiving groove 21, the second hook 3 is in the retracted position, as... Figure 2As shown, when the second hook 3 is moved outward from the receiving groove 21, the second hook 3 is in the unfolded position; as long as the second hook 3 is moved out of the receiving groove 21, it can be used for hanging items; such as Figure 2 As shown, preferably, the position of the second hook 3 when rotated 90° from the retracted position is the unfolded position. At this time, the second hook 3 and the first hook 2 are far apart, so that the objects suspended by the first hook 2 and the second hook 3 will not encroach on each other's required space and thus affect the suspension.

[0048] After use, rotate the second hook 3 to move both second hooks 3 from the unfolded position back to the retracted position (in the receiving groove 21), thus folding and retracting the medical hook.

[0049] In some embodiments of this application, such as Figure 2 As shown, the second hook body 3 includes a vertical part 32 and a hook part 31 connected to the bottom of the vertical part 32. The vertical part 32 extends vertically and is rotatably connected to the connecting part 123.

[0050] like Figure 1 As shown, an adjusting bolt 4 is threaded onto the connecting part 123, such as... Figure 7 As shown, a sliding rod 41 is coaxially connected to the bottom of the adjusting bolt 4. The sliding rod 41 is coaxially arranged with the vertical part 32, and the sliding rod 41 is axially movable and connected to the vertical part 32. Specifically, a sliding hole 321 that mates with the sliding rod 41 is coaxially provided in the vertical part 32 (the sliding hole 321 penetrates the vertical part 32 upwards so that the sliding rod 41 extends into the sliding hole 321). The inner wall of the sliding hole 321 is provided with a groove 324, and protrusions 42 are provided on both axial sides of the outer wall of the sliding rod 41. 1. Under the cooperation of the protrusion 42 and the groove 324, the axial part moves and connects to the sliding hole 321. When the adjusting bolt 4 is turned, the sliding rod 41 will rotate synchronously (at this time, the sliding rod 41 will move axially within the sliding hole 321). As the sliding rod 41 rotates, the vertical part 32 will rotate synchronously through the cooperation of the protrusion 42 and the groove 324, thereby moving the second hook 3 out of the receiving groove 21 and rotating it to the appropriate unfolding position. After the second hook 3 is rotated to the appropriate position, the adjustment bolt 4 is stopped, so that the second hook 3 can be stably maintained in the current position. The threaded engagement between the adjusting bolt 4 and the connecting part 123 is a self-locking bolt, which helps to reliably position the second hook 3 and prevent swaying when hanging items.

[0051] In some embodiments of this application, such as Figure 3 , Figure 6As shown, the hook portion 31 and the vertical portion 32 are connected at one end to an extension portion 311 that extends vertically. A downwardly penetrating receiving cavity 322 is provided coaxially within the vertical portion 32. The extension portion 311 is coaxially located within the receiving cavity 322 and is axially movable within the receiving cavity 322. When the second hook 3 is removed from the receiving groove 21, the hook portion 31 and the vertical portion 32 can move vertically, thereby adjusting the vertical position of the second hook 3. This allows the second hook 3 and the first hook 2 to be vertically offset by a certain distance, which is more conducive to hanging objects (infusion bottles, infusion bags, treatment information cards, or registration books, etc.). In this embodiment, by adjusting the vertical distance between the hook portion 31 and the vertical portion 32, the two second hooks 3 and the first hook 2 are made to have different vertical heights. When hanging objects, the objects can be appropriately offset, minimizing interference between the suspended objects.

[0052] like Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the first hook body 2 is provided with clearance grooves 22 on both sides along the first direction X, so that when the second hook body 3 needs to be adjusted in vertical height after rotating 90° from the retracted position, the clearance grooves 22 are provided to allow the hook part 31 and the extension part 311 to move downward.

[0053] In some embodiments of this application, such as Figure 6 As shown, this embodiment provides a specific method for axially moving the hook portion 31 relative to the vertical portion 32, as follows: The extension portion 311 is spaced apart from the inner wall of the accommodating cavity 322 (the outer diameter of the extension portion 311 is slightly smaller than the inner diameter of the accommodating cavity 322). An internally threaded cylinder 5 is rotatably mounted coaxially on the bottom wall of the vertical portion 32. The outer periphery of the extension portion 311 is provided with a threaded portion that threadedly engages with the internally threaded cylinder 5. The extension portion 311 is provided with a guide hole 3111 extending vertically. The accommodating cavity 322 is provided with a guide rod 323 that slides with the guide hole 3111 (the arrangement of the guide rod 323 and the guide hole 3111 prevents circumferential rotation between the extension portion 311 and the vertical portion 32). When the internally threaded cylinder 5 is rotated, the extension portion 311 moves axially within the accommodating cavity 322. By controlling the rotation angle of the internally threaded cylinder 5, the downward movement distance of the hook portion 31 is controlled (e.g., ...). Figure 3 (As shown).

[0054] In some embodiments of this application, such as Figure 1 , Figure 4As shown, the snap-fit ​​component 1 includes a first snap-fit ​​portion 11 and a second snap-fit ​​portion 12. The first snap-fit ​​portion 11 has a first arc-shaped groove 111 on the side facing the second snap-fit ​​portion 12, and the second snap-fit ​​portion 12 has a second arc-shaped groove 121 on the side facing the first snap-fit ​​portion 11. The first snap-fit ​​portion 11 and the second snap-fit ​​portion 12 are connected to a driving member. The driving member drives the first snap-fit ​​portion 11 and the second snap-fit ​​portion 12 to move closer together along the radial direction of the columnar structural member 8. The first arc-shaped groove 111 and the second arc-shaped groove 121 both abut against the outer wall of the columnar structural member 8, so that the snap-fit ​​component 1 snaps into the columnar structural member 8 (e.g., ...). Figure 5 (as shown); or the driving member drives the first snap-fit ​​part 11 and the second snap-fit ​​part 12 to move away radially from the columnar structure 8, so as to remove the snap-fit ​​part 1 from the columnar structure 8.

[0055] In some embodiments of this application, such as Figure 4 As shown, this embodiment provides a specific structure of a driving component, as follows: The driving component includes two snap-fit ​​bolts 13, both of which are threadedly assembled with the first snap-fit ​​part 11 and the second snap-fit ​​part 12 (the first snap-fit ​​part 11 is provided with first threaded holes 112 on both sides of the first arc-shaped groove 111, and the second snap-fit ​​part 12 is provided with second threaded holes 122 on both sides of the second arc-shaped groove 121). The snap-fit ​​bolts 13 are threadedly assembled in the first threaded holes 112 and the second threaded holes 122 on the same side. By rotating the two snap-fit ​​bolts 13, the first snap-fit ​​part 11 and the second snap-fit ​​part 12 are driven to move closer to each other, thereby snapping the snap-fit ​​component 1 onto the columnar structural component 8.

[0056] Alternatively, both locking bolts 13 can be completely withdrawn from the second threaded hole 122, causing the first locking part 11 and the second locking part 12 to separate, thereby allowing removal from the columnar structural member 8. Figure 4 The diagram illustrates the assembly method between the snap-fit ​​bolt 13 and the first threaded hole 112 and the second threaded hole 122. The first threaded hole 112 penetrates the first snap-fit ​​portion 11, and a relief cavity 113 is provided on the first snap-fit ​​portion 11 to accommodate the nut of the snap-fit ​​bolt 13 (i.e., the screwing part of the snap-fit ​​bolt 13, such as...). Figure 1 (As shown).

[0057] In some embodiments of this application, such as Figure 1 As shown, a first rubber layer 6 is provided on the inner wall of the first arc-shaped groove 111, and a second rubber layer 7 is provided on the inner wall of the second arc-shaped groove 121. The arrangement of the first rubber layer 6 and the second rubber layer 7 can achieve a better installation effect. When the first arc-shaped groove 111 and the second arc-shaped groove 121 press against the outer peripheral wall of the columnar structural member 8, they squeeze the first rubber layer 6 and the second rubber layer 7, causing them to deform and improving the snap-fit ​​effect (the installation is more secure).

[0058] The working process of this utility model is as follows: The two snap-fit ​​bolts 13 are removed from the second threaded hole 122, and the first arc-shaped groove 111 and the second arc-shaped groove 121 are aligned with the columnar structural member 8 (for mounting the lamp arm) on the dental chair. Then, the snap-fit ​​bolts 13 are screwed into the second threaded hole 122 until the first rubber layer 6 and the second rubber layer 7 press against the outer peripheral wall of the columnar structural member 8, thus installing the medical hook. Subsequently, according to usage requirements, the second hook body 3 is removed from the receiving groove 21, and its vertical height is adjusted for hanging infusion bottles (bags), treatment cards, or registration books. After use, the snap-fit ​​member 1 is removed from the columnar structural member 8, and the second hook body 3 is folded up to allow for easy storage in any relatively small space, even in treatment rooms with limited space.

[0059] In summary, this utility model embodiment provides a detachable medical hook. This solution uses a snap-fit ​​connector 1 to directly install the first hook 2 and the second hook 3, used for suspending infusion bottles (bags), onto the columnar structure 8 of the dental chair. This eliminates the need for an additional infusion stand next to the dental chair. Furthermore, since the first hook 2 and the second hook 3 are directly suspended on the columnar structure 8 of the dental chair, they do not encroach on the doctor's operating space next to the dental chair. After use, the snap-fit ​​connector 1 can be removed directly from the column, and the second hook 3 can be folded away, keeping the hook in a small size for easy storage. It can be placed in a drawer in the treatment room or any other relatively small space, and can be quickly retrieved and used the next time.

[0060] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
