Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an auxiliary fixing device for a hospital bed dining table. Background Technology

[0002] Patients need to eat in bed, and the dining table is a common part of the bed structure. Usually, the dining table is hinged to the bed frame by the table legs. When not in use, it can be folded down so that the dining table is flush with the foot of the bed and the table legs are flush with the bed frame near the foot of the bed. When in use, the dining table can be pulled up to make it horizontal.

[0003] Because the dining table can be laid down for storage without any auxiliary fixing devices, when in normal use and the table is in a horizontal position, the patient's movements will cause the table to wobble in the direction it is laid down and then tip over. Family members may also accidentally pull on it while walking around, causing the table to wobble and tip over. The wobbling and tipping of the table may result in food or related items being spilled and the bedding being soiled; in severe cases, it may cause burns to the patient's lower limbs or injuries from being hit by related items. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing dining tables lack auxiliary fixing devices, causing them to wobble and tip over during use, spilling food, soiling sheets, and even scalding or injuring patients. To address this problem, an auxiliary fixing device for a hospital bed dining table is proposed, comprising a clamping plate, a first screw, a locking plate, fixing rings, and a fixing strap. The clamping plate is U-shaped, with its opening facing downwards, and is clamped onto the bed frame between the dining table legs and the headboard.

[0009] In a preferred embodiment of the present invention, the bonding position between the Velcro front and back is adjustable, and the size of the closed loop is adjustable, resulting in a more stable wrapping and fixing of the tabletop and legs.

[0010] In a preferred embodiment of the present invention, the hook and loop fastener side and the hook and loop fastener backing side are located on the same side of the fixing strap, so that when the fixing strap is folded and glued, the overall surface is smoother and neater.

[0011] In a preferred embodiment of the present invention, a reinforcing mechanism is further provided on the inner side plate of the clamping plate. The reinforcing mechanism includes an extension plate, a bonding plate, a second screw, and a guide rod.

Detailed Embodiment

[0021] Next, the technical solutions in the embodiments of the present utility model will be described in detail in conjunction with the attached Figure 1-3 , of the present utility model. Embodiment 1

[0022] As Figure 1-2 shown, the present utility model is an auxiliary fixing device for a hospital bed table board, including a clamping plate 1, a first screw rod 2, a clamping plate 3, a fixing ring 4 and a fixing belt 6.

[0023] The clamping plate 1 is in a "C" shape, and the opening of the clamping plate 1 faces downward. The distance between the two side plates of the clamping plate 1 is greater than the width of the bed frame, so the clamping plate 1 can be stuck on the bed frame.

[0024] A threaded hole is opened on the outer side plate of the clamping plate 1. The first screw rod 2 is threadedly connected to the outer side plate through the threaded hole. One end of the first screw rod 2 is located outside the clamping plate 1, and a regulating handle is connected to this end for manually screwing the first screw rod 2; the other end of the first screw rod 2 is located between the two side plates of the clamping plate 1, and a clamping plate 3 is fixedly connected to this end.

[0025] By screwing the first screw rod 2, the distance between the clamping plate 3 and the inner side plate of the clamping plate 1 can be adjusted. Through the cooperation of the inner side plate of the clamping plate 1 and the clamping plate 3, the device can be clamped and fixed on the bed frame to complete the subsequent work.

[0026] In this embodiment, rubber pads 5 are bonded and fixed to the inner side plates of the clamping plate 1 and the opposing surfaces of the clamping plate 3. When clamped and fixed, the rubber pads 5 can protect the bed frame and reduce wear. Similarly, rubber pads 5 are also bonded and fixed to the lower surface of the upper plate of the clamping plate 1.

[0027] There is a distance between the clamping plate 3 and the lower surface of the upper plate of the clamping plate 1. When the clamping plate 3 is adjusted by the first screw 2, it will not scratch the rubber layer on the surface of the upper plate. The shape of the clamping plate 3 is not limited, but it is preferred to be circular. The specific reason is that after the first screw 2 is connected to the center of the clamping plate 3, the distance between the edge of the clamping plate 3 and the upper plate remains unchanged when adjusted by the first screw 2. Therefore, it is only necessary to ensure that the clamping plate 3 will not scratch the rubber pad layer 5 on the surface of the upper plate at the initial stage. When the clamping plate 3 is of other shapes, since the rotation of the first screw 2 will drive the clamping plate 3 to rotate together, it is necessary to ensure that the edge of the clamping plate 3 does not scratch the rubber pad layer 5 on the upper plate when rotating, regardless of any position.

[0028] A fixing ring 4 is installed on each of the two side plates of the splint 1. The fixing ring 4 is located on the upper part of the splint 1. The fixing ring 4 is used to cooperate with the fixing strap 6 to assist in fixing the dining table of the hospital bed and prevent the dining table from shaking and tipping over.

[0029] One end of the fixing strap 6 is a fixed end, which is fixedly connected to a fixing ring 4; the other end of the fixing strap 6 is a movable end, and the movable end of the fixing strap 6 is fixed to the Velcro face 62 by sewing. The surface of the fixing strap 6 on the same side is also fixed to the Velcro face 61.

[0030] The existing hospital bed dining table is supported by table legs, which are hinged to the bed frame. When in use, the table legs are rotated to move to their limit and become perpendicular to the bed frame, at which point the table table is parallel to the bed surface. After use, the table table is laid down, with the table legs touching the bed frame and the table table touching the foot of the bed. However, due to the lack of fixation, the table table may wobble in the direction of tipping over due to various accidents or negligence while in use.

[0031] This device is clamped and fixed between the headboard of the hospital bed and the dining table, specifically in the opposite direction of the dining table's tipping direction and close to the table legs. When the dining table is in use, it is perpendicular to the bed frame. At this time, simply pull the fixing strap 6 over the table legs and then through another fixing ring 4. Then flip the fixing strap 6 and tighten it, securing it with Velcro. At this point, the table legs are located between the fixing strap 6 and the clamp 1. Since the clamp 1 is located in the opposite direction of the table's tipping direction, the table cannot sway in the tipping direction due to the pulling of the fixing strap 6, preventing the table from accidentally swaying and tipping over, thus reducing the probability of related accidents.

[0032] Furthermore, when the fixing strap 6 is tightened, it will fit tightly against the table leg of the dining table board, and the fixing strap 6 is located above the hinge point of the table leg, so the table leg cannot tip over. Therefore, it achieves auxiliary fixation and prevents the dining table board from shaking and tipping over, which could lead to accidents.

[0033] The length of the hook and loop fastener female side 61 is sufficient to match the hook and loop fastener female side 62 at the movable end of the fixing strap 6, so that the fixing strap 6 can be tightened and glued in place.

[0034] This device is always clamped and fixed to the bed frame. When in use, simply fix the fixing strap 6 as described above. After use, untie the fixing strap 6, pull the side of the fixing strap 6 near the fixed end to pull out the movable end as a whole, and the dining table can be laid down normally. Then, flip the movable end of the fixing strap 6 over and fasten it with Velcro, and tuck the whole thing under the bed sheet or mattress. Pull it out again when you need to use it again.

[0035] The method of using the auxiliary fixing device for the hospital bed dining table in this embodiment is as follows:

[0036] With the opening of clamp 1 facing downwards, and the first screw 2 positioned on the outside of the hospital bed, it is then secured from top to bottom to the bed frame, not between the headboard and the table legs. Next, adjust its position to bring it closer to the table legs, rotate the first screw, causing clamp 3 to move inwards and engage with the inner side plate of clamp 1, gradually clamping the bed frame and fixing the device in place. When using the table, the movable end of the fixing strap 6 needs to pass through the space between the foot of the bed and the table legs, and then pass through another fixing ring 4. Next, fold the fixing strap 6 and tighten it, securing it with Velcro. The fixing strap 6 pulls on the table legs, preventing the table from wobbling in the direction it is laid down, thus preventing accidental tipping and reducing the probability of accidents. Example 2

[0037] like Figure 3 As shown, this embodiment adds a reinforcement mechanism to the embodiment 1. The reinforcement mechanism provides secondary reinforcement to the device in the vertical direction, making the device more stable.

[0038] The reinforcement mechanism is installed on the inner side plate of the clamping plate 1. The reinforcement mechanism includes an extension plate 7, a bonding plate 8, a second screw 9, and a guide rod 10.

[0039] The extension plate 7 is the part of the upper plate of the clamping plate 1 that extends outward. The lower wall of the extension plate 7 protrudes downward to form a guide rod 10. The lower end of the guide rod 10 is fixed with a limit block 11. The bonding plate 8 passes through the guide rod 10 and can slide along the guide rod 10. The second screw 9 is parallel to the guide rod 10. The upper end of the second screw 9 is rotatably connected to the extension plate 8. The other end of the second screw 9 is threadedly connected to the bonding plate 8 and extends out of the bonding plate. The lower end of the second screw 9 is fixed with an adjustment handle.

[0040] The distance between the bonding plate 8 and the upper plate of the clamping plate 1 is greater than the thickness of the bed frame, and part of the bonding plate 8 is located below the orthographic projection of the clamping plate 1. Therefore, by adjustment, the bonding plate can move vertically and fit against the lower surface of the bed frame, clamping the bed frame vertically and assisting in fixation.

[0041] By adjusting the handle, the second screw 9 can be rotated. When the second screw 9 rotates, the bonding plate 8 moves along the direction of the guide rod 10. The rubber pad layer 5 is bonded and fixed on the upper surface of the bonding plate 8. Through the cooperation of the bonding plate 8 and the upper plate of the clamping plate 1, it can be clamped from the vertical direction to reinforce the device a second time and further improve its stability.

[0042] It should be noted that, due to the presence of the reinforcement mechanism and the fact that part of the orthographic projection of the bonding plate 8 is located in the space below between the two side plates of the clamping plate 1, during installation, the clamping plate 3 needs to be adjusted to fit against the outer side plate of the clamping plate 1, and the bonding plate 8 should also be adjusted to the bottom. At this time, the distance between the two opposite surfaces of the bonding plate 8 and the clamping plate 3 reaches its maximum, and this distance is greater than the width of the bed frame. Therefore, it can be inserted into the bed frame for subsequent clamping and fixing.

[0043] The specific installation process is as follows: Place the clamping plate 3 against the outer surface of the bed frame, then vertically downwards, with the upper plate of the clamping plate 1 against the upper surface of the bed frame. Next, pull it horizontally outwards so that the inner side plate of the clamping plate 1 is against the bed frame. Then, by adjusting the first screw 2, the clamping plate 3 moves accordingly, gradually clamping the bed frame between the clamping plate 3 and the inner side plate of the clamping plate 1. Finally, adjust the second screw 9, and the bonding plate 8 moves upwards accordingly, cooperating with the upper plate of the clamping plate 1, achieving secondary reinforcement in the vertical direction and improving the stability of the fixation.

[0044] The above embodiments are only for illustrating the technical concept of this utility model and should not be used to limit the protection scope of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the protection scope of this utility model.
