Description

Technical Field

[0001] This utility model relates to the field of medical care, and specifically provides a bed-assisted operation panel. Background Technology

[0002] Patients undergoing surgeries such as anorectal surgery and laparoscopic surgery require hospitalization for observation. During this period, nurses need to perform routine nursing procedures such as dressing changes. However, due to industry regulations, treatment trays containing nursing equipment are prohibited from being placed on the bed except in emergency situations. Therefore, nurses must place the treatment trays on the bedside table before performing these procedures. In some wards, due to space constraints, only one bedside table is provided per bed. For some patients, due to their surgical location and lying position, it is more convenient to perform nursing procedures on the opposite side of the bedside table. However, the lack of a platform for placing the treatment tray forces nurses to repeatedly walk halfway around the bed to retrieve the necessary equipment from the bedside table; or temporarily change the patient's position in bed. The former greatly increases the workload and difficulty for nurses, while the latter requires patients to change their position, which can affect their recovery and cause discomfort. Therefore, resolving the problem of insufficient space, resulting in only one bedside table per bed and a lack of a platform for placing treatment trays, is extremely urgent. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a bedside auxiliary control panel that can be easily stored away.

[0004] The technical solution of this utility model is as follows:

[0005] A bedside auxiliary control panel includes a connecting cover, a drawer box, and a control panel body disposed in the drawer box. The connecting cover is fixedly disposed under the bed board, and the drawer box is slidably disposed under the connecting cover. The control panel body is disposed in the drawer box, and the control panel body is disposed inside the drawer box via a telescopic unit, and can also extend out of the drawer box via the telescopic unit.

[0006] In this design, the control panel is placed under the bed board without taking up extra space. By pulling out the drawer and controlling the telescopic unit, the control panel can be raised from the drawer box and the side of the bed, providing a platform for the treatment tray. This makes it easier for nurses to perform nursing care and also eliminates the need for patients to change positions, thus improving patient comfort. Furthermore, storing the control panel in the drawer box prevents the patient's bodily fluids from flowing down the bed and contaminating the control panel.

[0007] Preferably, the telescopic unit includes a first fixed section and a second sliding section. The second sliding section is connected to the operating panel body. The second sliding section is sleeved on the first fixed section and can slide axially relative to the first fixed section. The telescopic unit also includes a locking mechanism that restricts the relative position of the second sliding section and the first fixed section.

[0008] Preferably, the locking mechanism includes a first locking groove provided on the second sliding section and a locking protrusion provided on the surface of the first fixed section, wherein the locking groove and the locking protrusion cooperate with each other.

[0009] In this scheme, since the second sliding section is sleeved on the first fixed section, that is, at least part of the second sliding section is a cylindrical structure, when the second sliding section moves up to a certain position relative to the first fixed section, the locking protrusion of the first fixed surface is exactly at the position of the first locking groove of the second sliding section, and the locking protrusion is engaged in the first locking groove to achieve locking.

[0010] When the drawer box has limited space and cannot accommodate an operating panel body with sufficient area, preferably, the operating panel body includes two symmetrically arranged folding plates. The adjacent sides of the two folding plates are hinged to the ends of the second sliding section. Each folding plate has a support mechanism at its bottom. The support mechanism includes a support rod and a support ring. One end of the support rod is hinged to the bottom of the folding plate, and the other end is hinged to the support ring. The support ring is sleeved on the second sliding section. The support ring has a locking protrusion facing the axis inside. The locking protrusion is adapted to the second locking groove on the second sliding section. The first locking groove is closer to the first fixed section than the second locking groove.

[0011] In this design, the control panel body is designed with a symmetrical folding structure, which makes it easy to place the control panel body in a small drawer box. When the control panel body is pulled out, the two folding plates are combined to form a control panel body with sufficient area. Since the treatment tray will be placed on the control panel body, there is a load-bearing requirement. In order to meet the strength of the control panel body, the position of the fixed support ring is used to allow the support rod to support the control panel body from below the folding plate. The triangular support structure is also more stable.

[0012] Preferably, the locking protrusion is an elastic protrusion that can elastically deform when the locking mechanism is unlocked, thereby disengaging from the locking groove.

[0013] To facilitate the removal of the control panel body from the drawer box, a lifting and pressing component is inserted at the end of the second sliding section away from the first fixed section. The lifting and pressing component can slide axially relative to the second sliding section. A limit slider is provided at one end of the lifting and pressing component inserted into the second sliding section, and a handle is provided at the other end. The side wall of the limit slider slides against the inner wall of the second sliding section, and the limit slider prevents the lifting and pressing component from separating from the second sliding section.

[0014] In this design, after opening the drawer, the nurse can easily pull out the control panel by holding the handle, thus extending the telescopic unit.

[0015] Meanwhile, in order to facilitate the release of the locking protrusion from the first locking groove or the second locking groove, and to reduce the overall structural complexity of the operating panel body, preferably, the end face of the limiting slider facing the first fixed section is chamfered, and the limiting slider is moved down by pressing the lifting member to release the lock between the second locking groove and the locking protrusion on the support ring; the inner ring of the side of the support ring facing the top of the first fixed section is provided with a chamfered surface, and the locking mechanism is released by sliding the support ring. In this solution, no additional unlocking structure is required. In the already disclosed structure, when the lifting and pressing component is pressed, the limiting slider slides in the second sliding section. After contacting the locking protrusion on the support ring that matches the second locking groove, it continues to press down. The chamfered surface decomposes the downward force into a radial force, allowing the locking protrusion to undergo elastic deformation, thus releasing the positioning lock of the support ring and allowing the folding plate to rotate and be stored smoothly. After the positioning lock of the support ring is released, the support can continue to slide down along the second sliding section. Similarly, after contacting the locking protrusion on the surface of the first fixed section that matches the first locking groove, it continues to move down. The chamfered surface decomposes the downward force into a radial force, allowing the locking protrusion to undergo elastic deformation, thus releasing the length lock of the telescopic unit and allowing the control panel body to retract into the drawer box.

[0016] To ensure that a sufficiently small drawer box can accommodate a sufficiently large control panel, and to ensure that the control panel can be pulled out even if the drawer box opening is too small, preferably, the inner bottom of the drawer box is provided with a slide rail and a slider adapted to the slide rail. A connecting block is rotatably connected to the slider. The slide rail is located on the rotation plane of the connecting block. The first fixed section is fixedly mounted on the connecting block. Rotation limiting plates are provided on both sides of the connecting block. The rotation limiting plates limit the maximum rotation angle of the connecting block to be perpendicular to the slide rail. A rotation locking mechanism is also provided between the connecting block and the slider. The rotation locking mechanism restricts the rotation of the first fixed section.

[0017] In this design, after the folding panel is folded and stowed, it fits into the second sliding section. When the slider moves to the innermost part of the drawer box, the folding panel can be completely stowed inside the box. Even if the drawer box is only pulled out halfway, the folded operating panel can still be pulled out of the drawer box at an angle through the rotatable structure of the first fixed section and the slider. Furthermore, by rotating the limiting plate, the first fixed section is prevented from rotating excessively. When it reaches its limit, the entire telescopic unit can extend vertically out of the box, and the rotation is restricted by the rotation locking mechanism.

[0018] Preferably, the rotation locking mechanism includes a ratchet structure on the slider and a first pawl on the connecting block that is adapted to the ratchet structure, thereby restricting the rotation of the first fixed segment toward the track direction.

[0019] In this design, when the ratchet and the first pawl work together, they can restrict the rotation of the first fixed section in one direction, but they will not restrict the rotation of the main body of the control panel when it is pulled out. After the telescopic unit is vertically perpendicular to the bottom of the drawer box, the rotation is automatically locked by the ratchet and the first pawl. The stability of the main body of the control panel can be guaranteed during use without the need for the nurse to lock it.

[0020] Preferably, the slide rail is further provided with a distance fixing mechanism, which can limit the position of the slider on the slide rail; the distance fixing mechanism can prevent the operating panel body from moving during use (the distance fixing mechanism includes a ratchet section provided at the end of the slide rail and a second pawl provided on the connecting block; when the first fixed section is perpendicular to the track, the second pawl is adapted to the ratchet section, which restricts the movement of the slider in the depth direction of the drawer box). A sealing strip is provided at the contact position between the drawer box and the connecting cover to further prevent the patient's leaked body fluid from flowing out along the bed board and entering the drawer box to contaminate the operating panel.

[0021] The beneficial effects of this utility model are as follows: This utility model places the control panel body under the bed board without occupying extra space. By pulling out the drawer and controlling the telescopic unit, the control panel body can be raised from the drawer box and the side of the bed to provide a platform for the treatment tray, which makes it easier for nurses to perform nursing care. At the same time, it does not require the patient to change position, thus improving the patient's comfort. Furthermore, storing the control panel body in the drawer box can prevent the patient's bodily fluids from flowing down the bed and contaminating the control panel. Attached Figure Description

Detailed Implementation

[0031] The technical solution of the present invention will be clearly and completely described in conjunction with the accompanying drawings and through specific implementation methods of the embodiments of the present invention.

[0032] Example 1:

[0033] A type of bedside assistive control panel, such as Figures 1 to 3 As shown, the device includes a connecting cover 1, a drawer box 2, and an operating panel body 3 disposed in the drawer box 2. The connecting cover 1 is fixedly disposed under the bed board 5. The drawer box 2 is slidably disposed under the connecting cover 1. The operating panel body 3 is disposed in the drawer box 2. The operating panel body 3 is disposed inside the drawer box 2 through a telescopic unit 4, and can also extend out of the drawer box 2 through the telescopic unit 4.

[0034] In this embodiment, the control panel body 3 is placed under the bed board 5 without occupying extra space. By pulling out the drawer, the telescopic unit 4 is controlled to rise from the drawer box 2 and the side of the bed, providing a platform for the treatment tray. This makes it easier for nurses to perform nursing care and also eliminates the need for patients to change positions, thus improving patient comfort. Furthermore, storing the control panel body 3 in the drawer box 2 prevents the patient's bodily fluids from flowing down the bed and contaminating the control panel.

[0035] Specifically, the bottom surface of the connecting cover 1 is equipped with guide rails, and the top of the two vertical long sides of the drawer box 2 is equipped with pulleys adapted to the guide rails, increasing the stability of the drawer box 2 when moving relative to the connecting cover 1. A sealing strip is provided at the contact point between the drawer box 2 and the connecting cover 1 to further prevent patient leakage of bodily fluids from flowing along the bed board 5 and entering the drawer box 2 to contaminate the operating panel. This also increases the friction when the drawer box 2 is pulled out, preventing it from moving even with a slight touch after being pulled out.

[0036] The telescopic unit 4 can be a spring-loaded structure, a more expensive pneumatic telescopic rod structure, or a threaded telescopic structure, etc. This invention preferably uses a manual telescopic rod structure, such as... Figure 1 and Figure 2 As shown, the telescopic unit 4 includes a first fixed section 401 and a second sliding section 402. The second sliding section 402 is connected to the operating panel body 3, and is sleeved on the first fixed section 401, allowing it to slide axially relative to the first fixed section 401. The telescopic unit 4 also includes a locking mechanism to restrict the relative position of the second sliding section 402 and the first fixed section 401. Simultaneously, the surface of the first fixed section 401 is provided with a guide groove, and the inner wall of the second sliding section 402 is provided with guide ribs, or vice versa. The locking mechanism includes a first locking groove 403 on the second sliding section 402 and a locking protrusion 409 on the surface of the first fixed section 401, with the locking groove and the locking protrusion 409 cooperating with each other. Since the second sliding section 402 is sleeved on the first fixed section 401, that is, at least part of the second sliding section 402 is a cylindrical structure, when the second sliding section 402 moves up to a certain position relative to the first fixed section 401, the locking protrusion 409 of the first fixed surface is exactly at the position of the first locking groove 403 of the second sliding section 402, and the locking protrusion 409 is engaged in the first locking groove 403 to achieve locking.

[0037] It should be noted that in this embodiment, the telescopic unit 4 only includes the first fixed section 401 and the second telescopic section. If actual conditions permit, it may also include a third telescopic section, a fourth telescopic section, etc. These extra telescopic sections are all set between the first fixed section 401 and the second telescopic section.

[0038] Example 2:

[0039] Generally, to save costs or due to space constraints, the size of drawer box 2 is subject to requirements and limitations. A complete operating panel cannot be directly stored in drawer box 2. Therefore, when the internal space of the storage box is limited and cannot accommodate an operating panel body 3 of sufficient area, based on embodiment one, as follows... Figure 1 or Figure 7 As shown, the operation panel body 3 includes two symmetrically arranged folding plates 301. The adjacent sides of both folding plates 301 are hinged to the ends of the second sliding section 402. Each folding plate 301 has a support mechanism at its bottom, including a support rod 302 and a support ring 303. One end of the support rod 302 is hinged to the bottom of the folding plate 301, and the other end is hinged to the support ring 303. The support ring 303 is fitted onto the second sliding section 402. The support ring 303 has a locking protrusion 409 facing the axis inside. The locking protrusion 409 is adapted to a second locking groove 404 on the second sliding section 402. The first locking groove 403 is closer to the first fixed section 401 than the second locking groove 404. When the two folding plates 301 are rotated to be parallel to the two plate surfaces, they are in a retracted state, occupying half the area. When the folding plate 301 is in the retracted state, the support ring 303 is positioned closer to the first locking groove 403 in the second locking groove 404. As the folding plate 301 unfolds, the support ring 303 gradually moves towards the second locking groove 404. When the folding plate 301 is fully unfolded to form the complete control panel body, the support ring 303 is precisely positioned in the second locking groove 404, and the locking protrusion 409 on the inner surface of the support ring 303 engages with the second locking groove 404, thus achieving locking. Therefore, the strength requirements of the control panel body 3 are met, and by fixing the position of the support ring 303, the support rod can support the control panel body 3 from below the folding plate 301, and the triangular support structure is more stable.

[0040] It should be noted that the accompanying drawings are for illustrative purposes only. The size of the folding plate 301 and its horizontal orientation after unfolding are determined according to the actual space available in the usage scenario. Furthermore, the locking protrusion 409 in Embodiment 1 and this embodiment is an elastic protrusion, capable of elastically deforming when the locking mechanism is unlocked, thereby disengaging from the locking groove. The protruding surface of the locking protrusion 409 is an arc-shaped protrusion.

[0041] Furthermore, such as Figure 2As shown, to facilitate the removal of the control panel body 3 from the drawer box 2, a lifting and pressing member 405 is inserted at the end of the second sliding segment 402 away from the first fixed segment 401. The lifting and pressing member 405 can slide axially relative to the second sliding segment 402. A limiting slider 406 is provided at one end of the lifting and pressing member 405 inserted into the second sliding segment 402, and a handle 407 is provided at the other end. The side wall of the limiting slider 406 slides against the inner wall of the second sliding segment, preventing the lifting and pressing member 405 from separating from the second sliding segment 402. With this arrangement, when the telescopic unit is shortened for storage, the first fixed segment 401 is inserted into the second sliding segment 402, and the end of the first fixed segment 401 abuts against the limiting slider 406, causing the handle 407 to extend from the end of the second sliding segment 402. When the nurse opens the drawer, by holding the handle 407, the control panel body 3 can be pulled out easily, and the telescopic unit 4 can be extended.

[0042] Furthermore, to facilitate the release of the locking protrusion 409 from the first locking groove 403 or the second locking groove 404, and to reduce the overall structural complexity of the operation panel body 3, such as... Figure 4 As shown, the limiting slider 406 has a chamfered bevel facing the end face of the first fixed section 401. By pressing the lifting member 405, the limiting slider 406 moves downward and releases the lock between the second locking groove 404 and the locking protrusion 409 on the support ring 303. The inner ring of the side of the support ring 303 facing the top of the first fixed section 401 has a chamfered bevel. By sliding the support ring 303, the lock of the locking mechanism is released. In this solution, no additional unlocking structure is required. In the disclosed structure, when the lifting member 405 is pressed, the limiting slider 406 slides in the second sliding section 402. After contacting the locking protrusion 409 on the support ring 303 that matches the second locking groove 404, it continues to press down. The chamfered bevel decomposes the downward force into a radial force, allowing the locking protrusion 409 to undergo elastic deformation, releasing the positioning lock of the support ring 303, allowing the folding plate 301 to rotate and be stored smoothly. The limiting slider 406 is provided with a limiting bevel. Pull cord 408 prevents excessive pressing and limits the downward movement distance of limit slider 406; after the positioning lock of support ring 303 is released, the support can continue to slide downward along the second sliding section 402, and after contacting the locking protrusion 409 that matches the first locking groove 403 on the surface of the first fixed section 401, it continues to move downward. The downward force is decomposed into a radial force by the chamfered bevel, allowing the locking protrusion 409 to undergo elastic deformation, releasing the length lock of telescopic unit 4, and allowing the operation panel body 3 to retract into drawer box 2.

[0043] Of course, a dedicated operating component can also be set up. The operating component is connected or linked to the locking protrusion 409. By operating the operating component, the locking protrusion 409 can be actively disengaged from or enter the locking groove.

[0044] Example 3:

[0045] The setup in Example 2 is suitable for boxes with sufficient height. However, when the box is relatively flat, the control panel body needs to have sufficient height and storage area. Therefore, in order to ensure that a sufficiently large control panel body 3 can be accommodated in a sufficiently small drawer box 2, and also to ensure that the control panel body 3 can be pulled out even if the opening of the drawer box 2 is too small, based on Example 2, as follows... Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the drawer box 2 has a slide rail 6 and a slider 7 adapted to the slide rail 6 on its inner bottom. A connecting block 8 is rotatably connected to the slider 7. The slide rail 6 is located on the rotation plane of the connecting block 8. The first fixed section 401 is fixedly installed on the connecting block 8. Rotation limiting plates 801 are provided on both sides of the connecting block 8. The rotation limiting plates 801 limit the maximum rotation angle of the connecting block 8 to be perpendicular to the slide rail 6. A rotation locking mechanism is also provided between the connecting block 8 and the slider 7 to restrict the rotation of the first fixed section 401. After the folding plate 301 is folded and stored, it fits against the second sliding section 402. When the slider 7 moves to the innermost part of the drawer box 2, the folding plate 301 can be completely stored in the box. Even if the drawer box 2 is only pulled out halfway, the folded operation panel body 3 can be pulled out of the drawer box 2 at an angle through the rotatable structure of the first fixed section 401 and the slider 7. Furthermore, by rotating the limiting plate 801, the first fixed section 401 is prevented from rotating excessively. When it reaches its limit, the entire telescopic unit 4 can extend vertically out of the box and the rotation is restricted by the rotation locking mechanism.

[0046] Specifically, the rotation locking mechanism includes a ratchet structure 701 on the slider 7 and a first pawl 802 on the connecting block 8 that is adapted to the ratchet structure 701. The rotation locking mechanism restricts the rotation of the first fixed section 401 in the track direction.

[0047] When the ratchet and the first pawl 802 are engaged, although they can restrict the rotation of the first fixed section 401 in one direction, they will not restrict the rotation of the main body of the control panel when it is pulled out. After the telescopic unit 4 is vertically perpendicular to the bottom of the drawer box 2, the rotation is automatically locked by the engagement of the ratchet and the first pawl 802. The stability of the main body of the control panel can be guaranteed during use without the need for the nurse to lock it.

[0048] Furthermore, a distance-fixing mechanism is also provided on the slide rail 6, which can limit the position of the slider 7 on the slide rail 6; the distance-fixing mechanism can prevent the operation panel body 3 from moving during use, such as... Figure 2As shown, the distance fixing mechanism includes a ratchet section 601 at the end of the slide rail 6 and a second pawl 803 on the connecting block 8. When the first fixing section 401 is perpendicular to the track, the second pawl 803 is adapted to the ratchet section 601, thereby restricting the movement of the slider 7 in the depth direction of the drawer box 2.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
