Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary equipment technology, specifically to a bedside tableboard anti-tilting fixation structure, which is mainly used to solve the problem of bedside tableboards easily tilting up and causing patients to fall. It is applicable to various hospital bedside tableboard fixing scenarios. Background Technology

[0002] In routine hospital diagnosis and care, bedside trays are crucial components for assisting patients with eating and placing items, and their stability directly affects patient safety. Currently, most bedside trays used in clinical practice employ simple overlapping or snap-fit ​​connections, which have limited fixing strength to the bed frame. When frail hospitalized patients, especially elderly patients, postoperative recovery patients, or those with limited mobility, attempt to use the tray for support to stand, adjust their position, or move, the tray is prone to tilting, wobbling, or even falling off due to uneven force.

[0003] Instability can cause patients to lose their support suddenly, leading to a risk of falls. Clinical data shows that about 15% of hospital patient falls are directly related to the instability of bedside facilities, including bedside tables. Patients who are physically weak or who touch or hold onto unstable bedside tables are more prone to falls. Falls can cause physical injuries such as fractures, traumatic brain injury, and soft tissue contusions, prolong hospital stays, increase treatment costs, and may also lead to medical disputes. Furthermore, they can have negative psychological effects on patients, such as fear and anxiety, seriously affecting treatment adherence and the recovery process.

[0004] In addition, some traditional methods of fixing food boards use adhesive backing for auxiliary fixing structures. After long-term use, the adhesive surface is prone to aging and losing its stickiness, which further aggravates the problem of food board loosening and becomes a potential safety hazard in clinical nursing.

[0005] Therefore, developing a reliable and easy-to-operate bedside tableboard anti-tilting fixation device is of great practical significance for improving the safety of medical care. Utility Model Content

[0020] like Figure 1-3 As shown, The fixation device mainly consists of two parts: the fixation body 1 and the fixation connector 10. The two parts work together to fix the dining board to the hospital bed. The structure and connection relationship of each component are as follows: Structural design of the fixture body 1 The fixation body 1 is the basic support component of the entire device. Its thickness is greater than that of the fixation connector 10 to ensure that the body has sufficient support strength to meet the fixation requirements of the hospital bed.

[0021] Movable clamp structure: A movable clamp is rotatably connected to the upper front side of the fixing body 1 via a first rotating shaft 5 and a second rotating shaft 6. The movable clamp includes an upper fastening part 7 and a lower movable part 4. The fastening part 7 is rotatably connected to the front side of the fixing body 1 via the first rotating shaft 5, and the movable part 4 is rotatably connected to the front side of the fixing body 1 via the second rotating shaft 6. The movable part 4 can drive the fastening part 7 to rotate synchronously around the first rotating shaft 5 by swinging up and down in an arc shape, so as to realize the engagement and disengagement control of the connecting hook and the fixing hook.

[0022] Connecting hook 8: A connecting hook 8 is integrally formed on one side of the upper end of the fastening part 7. The connecting hook 8 has an L-shaped structure and is used to engage with the fixing hook 9 of the fixing connector 10.

[0023] Recessed groove 2 and bolt structure 3: A recessed groove 2 is provided at the lower part of the fixation body 1. Several bolt structures 3 are provided in the middle of the recessed groove 2. The bolt structures 3 penetrate the fixation body 1 and the backing plate 12 on the rear side. They can be threadedly connected to the preset mounting holes at the end of the hospital bed or the metal frame, providing a bolt fixing method suitable for scenarios requiring high-strength fixation.

[0024] Adhesive backing plate 12: Adhesive backing plate 12 is attached to the back side of the fixation body 1. Adhesive backing plate 12 uses strong waterproof double-sided adhesive. After removing the protective film, it can be directly pasted onto the flat surface at the foot of the bed to provide a pasting and fixing method without drilling, and is suitable for different bed structures.

[0025] Installation method of the rotating shaft: Both rotating shaft 5 and rotating shaft 6 extend horizontally through both sides of the fixing body 1 to ensure the stability of the connection between the movable clamp and the body and to prevent the rotating shaft from loosening or falling off after long-term use.

[0026] Structural design of the fastener connector 10: The fastener connector 10 is an adapter component that connects to the dining board. Its front end is integrally formed with a fixing hook 9. The shape and size of the fixing hook 9 are completely matched with the connecting hook 8 on the fastener body 1. The two can be tightly engaged to achieve quick docking and fixing of the fastener body 1 and the fastener connector 10.

[0027] Adhesive backing plate 2 11: Adhesive backing plate 2 11 is pasted on the back side of the fastener connector 10. Adhesive backing plate 2 11 is made of the same material as adhesive backing plate 1 12. After removing the protective film, it can be directly pasted to the corresponding position of the bedside table to ensure a firm connection between the connector and the table without damaging the surface of the table.

[0028] Overall fixing principle: The fixture body 1 is fixed to the end of the hospital bed by the adhesive backing plate 12 or the bolt structure 3, and the fixture connector 10 is fixed to the corresponding position of the dining board by the adhesive backing plate 11. When in use, the downward arc swinging movable part 4 drives the fastening part 7 to rotate around the rotating shaft 5, so that the connecting hook 8 and the fixing hook 9 are fully engaged, realizing a firm connection between the dining board and the hospital bed. When disassembling, the upward arc swinging movable part 4 drives the fastening part 7 to rotate in the opposite direction, so that the connecting hook 8 and the fixing hook 9 are separated, and the dining board can be removed.

[0029] Installation of Fixture Body 1: If the foot of the hospital bed is a flat plastic or metal surface, simply peel off the protective film of the backing plate 12, and stick the fixation body 1 to the foot of the hospital bed near the end of the table board connection. Press for 30 seconds to ensure that it is firmly attached. If the foot of the hospital bed requires higher fixation strength, such as in scenarios with long-term heavy loads, it can be fixed by bolt structure 3 in the recessed groove 2: first, cut the adhesive layer of the backing plate 12 corresponding to the bolt position, then pass the bolt through the preset hole between the fixation body 1 and the foot of the hospital bed, and tighten the nut to complete the fixation.

[0030] Installation of the fastener connector 10: Unfold the hospital bed tray to the usage position, and mark the installation point in the corresponding area of ​​the tray according to the position of the connecting hook 8 on the fixation body 1; Peel off the protective film from the adhesive backing 11, and attach the fixing hook 9 of the fastener connector 10 to the marked point on the dining board with the hook 8 facing the direction of the fastener connector 8. Press for 30 seconds to ensure that it is firmly attached.

[0031] Usage and disassembly process: Usage: When the patient needs to eat, move the movable part 4 by hand to rotate it along the second pivot 6 and lift it up. At the same time, the movable part 4 drives the fastening part 7 to rotate outward along the first pivot 5, causing the connecting hook 8 to open, thus separating the dining board from the end of the bed. Then unfold the dining board to be flush with the bed and push the dining board so that the fixing hook 9 enters the engagement range of the connecting hook 8. When putting the dining board away, press down on the movable part 4 and rotate it in the opposite direction along the second pivot 6. The rotation pushes the fastening part 7 to rotate inward along the first pivot 5, so that the connecting hook 8 and the fixing hook 9 are tightly engaged. At this time, the dining board is firmly fixed and there is no risk of it lifting up.

[0032] Disassembly process: After the meal, press the movable part 4 to separate the connecting hook 8 from the fixed hook 9, and then the plate can be folded or removed.

[0033] Example 1: Scene of an adult patient's bed in a general ward When installing the anti-tilting fixation structure of this utility model on a bed used by adult patients in a general ward, first select a position with a flat edge of the bed board that is easy to operate. Remove the protective paper from the backing adhesive plate 12 on the back of the fixation body 1 and attach it to the preset position on the side of the bed board so that the recessed groove 2 is accurately fitted with the edge of the bed board to achieve initial positioning and fixation. Then, connect the fixation connector 10 to the bottom of the dining board on the side away from the bed board through the backing adhesive plate 11.

[0034] Then, the fixation body 1 is fastened to the bed board by the bolt structure 3 in the middle of the recessed groove 2 to ensure that the fixation body 1 will not be displaced. When the dining board needs to be placed, the medical staff or the patient lifts the pressing part at the lower end of the movable part 4 upwards, so that the movable part 4 rotates outwards. At this time, the connecting hook 7 at the upper end of the movable plate 6 opens accordingly.

[0035] After aligning the connecting hook 7 of the edge connector 10 of the table board with the edge connector, press the movable part 4 to move it downwards. At the same time, the connecting hook 7 rotates inwards until it hooks the fixing hook 9 of the connector 10. The front end of the connecting hook 7 engages with the inner side of the movable plate 6 and locks the table board in place, preventing it from moving left or right.

[0036] Example 2: Multifunctional bed scenario in a rehabilitation ward The multi-functional hospital beds in rehabilitation wards require greater stability and adaptability of the tray fixation device because the beds may need to be adjusted frequently.

[0037] During installation, the recessed groove 2 of the fixation body 1 is adapted to the thicker edge structure of the multi-functional hospital bed board. After initial fixation by the backing adhesive plate 9, secondary reinforcement is carried out by the bolt structure 3 that passes through the fixation body 1 and the backing adhesive plate 9 to ensure that the fixation will not loosen when the hospital bed is adjusted. The fixation connector 10 is connected to the bottom of the dining board on the side away from the bed board through the backing adhesive plate 11.

[0038] When rehabilitation patients are doing sit-up training, they need to use a meal board to support their bodies. At this time, the connecting hook 7 of the movable board 6 tightly hooks the fixing connector 10 and the adhesive backing board 11 of the meal board. The limiting part effectively restricts the lateral movement of the meal board and prevents the meal board from shifting due to uneven force exerted by the patient.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
