Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to an emergency protection device for preventing patients from falling out of bed during cardiac care. Background Art

[0002] Patients hospitalized in the cardiology department often experience changes in cardiac output and blood pressure due to taking medications to treat heart and related diseases, which leads to slow heart rate and insufficient blood supply to organs such as the heart and brain, causing fatigue or transient syncope symptoms.

[0003] At present, the most common measure adopted by hospitals to prevent patients from falling out of bed is to install guardrails on the edge of the bed. These guardrails are divided into two types: fixed and movable. Although fixed guardrails provide a certain degree of protection, they are not convenient for patients who have just finished surgery and there is a certain risk of falling; although movable guardrails can be folded or unfolded manually, when patients need to get out of bed, they need to turn sideways and do manual operation, which is not only troublesome, but also easy to cause patients to fall in the process of folding the guardrails.

[0004] The shortcomings of the existing technology are mainly reflected in three aspects: first, the anti-falling bed response is not timely, and it is impossible to respond quickly when the patient is about to fall out of bed; In addition, the existing fall protection system uses electronic control and needs to be manually closed when getting out of bed to avoid misjudgment, which increases the risk of falling out of bed. Misjudgment can also cause additional damage to the patient. Summary of the invention

[0005] The main purpose of the present invention is to provide an emergency protection device for preventing patients from falling out of bed for cardiac care, which can effectively solve the problems that existing devices cannot respond quickly when patients are about to fall out of bed and that misjudgment may increase the risk of falling out of bed.

[0012] Preferably, a cable 1 is wound around the inner surface of the gear, and one end of the cable 1 away from the gear extends upward along the connecting column and passes through the adjacent end surface of the support plate to the inner side of the protective structure and is fixedly connected to the protective structure.

[0013] Preferably, the protection structure includes a protection component slidably connected to the side wall of the support plate, and a protection locking component fixedly connected to the adjacent isolation guardrail is provided on the side of the protection component close to the inner wall of the bed, and the protection locking component is arranged on the adjacent inner surface of the bed.

[0014] Preferably, the protection assembly includes a protection plate slidably connected to the side wall of the support plate via a T-block, a sliding groove slidably connected to the T-block is provided on the side of the protection plate close to the support plate, an end of the cable away from the gear passes through the T-block, extends to the inner surface of the sliding groove and is fixedly connected to the bottom wall of the inner surface of the sliding groove, and two locking grooves slidably connected to the protection locking assembly are provided on the side of the protection plate away from the support plate, the locking groove is L-shaped and its horizontal part is symmetrically distributed along the middle of the protection plate, and the width of the horizontal part of the locking groove is twice the width of the vertical part.

[0015] Preferably, the protective locking assembly includes two cables fixedly connected to the adjacent isolation guardrails and an installation groove opened on the inner surface of the bed near the isolation guardrail on the same side.

The slider is slidably connected to the horizontal part of the locking groove and its width is equal to the width of the vertical part of the locking groove.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention utilizes the functions of the hinged seat, the isolation guardrail and the buckle seat to provide preliminary protection for the patient when the patient is on the upper part of the protection drive structure. At the same time, the isolation guardrail and the protection structure are used to cooperate to put the protection structure in a working state. When the patient flips to one side above the protection drive structure, the protection drive structure and the protection structure cooperate to drive the protection structure to rise, providing a barrier for the patient and preventing the patient from falling from the bedside.

[0017] 2. The present invention utilizes the cooperation of the isolation guardrail and the protective structure at the same time, and locks the protective structure when the isolation guardrail needs to be retracted when getting out of bed, so as to avoid the protective structure being mistakenly raised during the process of getting out of bed and causing additional damage to the patient.

[0018] 3. When the patient is on one side of the bed board, the cooperation of the arc groove and the central axis drives the bed board to rotate around the central axis of this side, and compresses the buffer component to make it move downward. When the release head compresses the connecting column to move downward, the gear pulls the cable one to move downward, and the cooperation of the gear and the rack is simultaneously utilized to make the cable one wrap around the axis of the gear. The slight pressure of the bed board on the release head drives the protective plate to rise rapidly along the support plate, thereby forming a barrier to prevent the patient from continuing to roll over and fall from the current side.

[0019] 4. The present invention cooperates with the isolation guardrail and the second cable. When it is necessary to get out of bed and retract the isolation guardrail, the isolation guardrail is used to pull the second cable to drive the slider to slide in the installation groove and the locking groove. During the sliding process of the slider, it will slide from the vertical part of the locking groove into the horizontal part. At this time, the rising path of the protective plate is blocked by the slider. Even if the bed board is unevenly stressed due to the action of getting out of bed, the buffer assembly cannot descend under the traction of the protective plate and the first cable, and support will be provided for the release head to prevent it from rotating. At this time, the patient can get out of bed safely to avoid additional damage to the patient due to the anti-fall function, thereby improving the flexibility of equipment use and reducing the probability of patient injury.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] Embodiment 1, as Figure 1 As shown, an emergency protection device for preventing patients from falling out of bed for intracardiac nursing comprises a bed body 1, guardrail structures 2 are symmetrically arranged at the left and right ends of the bed body 1, a protection drive structure 3 is arranged at the lower part of the inner cavity of the bed body 1, a pillow 5 is arranged at the rear part of the upper end of the protection drive structure 3, and protection structures 4 that are symmetrically arranged on the left and right sides of the inner surface of the bed body 1 and are in contact with the left and right ends of the protection drive structure 3.

[0024] Further, to ensure safety and to assist in preventing patients from falling, see Figure 2 The guardrail structure 2 includes a plurality of articulated seats 22 linearly distributed and fixedly connected to the side of the bed body 1, the inner surfaces of the plurality of articulated seats 22 are connected to the isolation guardrails 23 by rotation together, and a plurality of buckle seats 21 fixedly connected to the adjacent end surfaces of the bed body 1 are linearly distributed and fixedly connected above the plurality of articulated seats 22. The isolation guardrails 23 are clamped with the inner surfaces of the buckle seats 21 in a vertical state, and the outer surface of the isolation guardrails 23 is fixedly connected to the protective structure 4 on the side close to the bed body 1.

[0025] The isolation guardrail 23 rotates on the inner surface of the hinge seat 22. When the isolation guardrail 23 rotates to a vertical state, it can be buckled together with the buckle seat 21 and fixed in a vertical state by the buckle seat 21. At this time, the isolation guardrail 23 can provide preliminary protection and prevent external collisions from affecting the patient. The accompanying personnel can pull the isolation guardrail 23 hard to disengage it from the buckle seat 21, and rotate it around the hinge seat 22 to rotate it to a vertical downward state. At this time, the patient can get out of bed from the current side.

[0026] During the operation of this embodiment, the articulated seat 22, the isolation guardrail 23 and the buckle seat 21 are first used to provide preliminary protection for the patient when the patient is on the upper part of the protection drive structure 3. At the same time, the isolation guardrail 23 and the protection structure 4 are used to cooperate to put the protection structure 4 in a working state. When the patient flips to one side above the protection drive structure 3, the protection drive structure 3 and the protection structure 4 cooperate to drive the protection structure 4 to rise, thereby providing a barrier for the patient and preventing the patient from falling from the bedside. At the same time, the isolation guardrail 23 and the protection structure 4 cooperate to lock the protection structure 4 when it is necessary to get out of bed and retract the isolation guardrail 23, thereby preventing the protection structure 4 from erroneously rising during the process of getting out of bed and causing additional damage to the patient.

[0027] Embodiment 2. Based on embodiment 1, when the patient is on one side of the bed board 311, the arc groove 313 and the central axis 322 cooperate to drive the bed board 311 to rotate around the central axis 322 on this side, and compress the buffer assembly 33 to make it move downward. When the release head 331 compresses the connecting column 333 to move downward, the cable 1 336 is pulled downward by the gear 334, and the gear 334 and the rack 335 cooperate to make the cable 1 336 wrap around the axis of the gear 334. The slight pressure of the bed board 311 on the release head 331 drives the protective plate 411 to rise rapidly along the support plate 32, thereby forming a barrier to prevent the patient from continuing to roll over and fall from the current side.

[0028] Specifically, in order to achieve a slight tilt following the patient's flipping action and drive the buffer component 33 to move, refer to Figure 2 and Figure 4A support assembly 31 is arranged on the upper side of the support plate 32, and the support assembly 31 includes a bed board 311 which is tightly attached to the upper arc surfaces of the two support blocks 321, and arc plates 312 are fixedly connected to the positions of the four central axes 322 at the lower end of the bed board 311, and arc grooves 313 connected to the rear ends of the four arc plates 312 are arranged at the front ends, and the arc surfaces of the arc plates 312 on the left and right sides are in opposite directions.

[0029] Further, in order to provide support for the support assembly 31 and assist the support plate 32 to produce a slight deviation following the patient's turning over action, see Figure 3 and Figure 5 The protection driving structure 3 includes a support plate 32 fixedly connected to the middle of the inner surface of the bed body 1, and the upper end of the support plate 32 is symmetrically fixedly connected to support blocks 321, and the front and rear ends of the two support blocks 321 are fixedly connected to the central axis 322.

[0030] The upper side of the bed board 311 is covered with a sponge pad with a soft texture, which can improve the patient's comfort. The arc-shaped plate 312 at the bottom is mainly used to cooperate with the central axis 322. When the patient is on one side of the bed board 311, the central axis 322 is on the upper side of the arc-shaped groove 313 on the same side, and follows the pressure of the patient to make the bed board 311 unevenly stressed and rotate around the central axis 322 on this side. At the same time, the compression effect of the bed board 311 on the buffer component 33 is used to prompt the buffer component 33 to drive the protective structure 4 to move, prompting the protective structure 4 to rise, thereby protecting the side where the patient is located and preventing the patient from falling.

[0031] Further, in order to realize that the protective structure 4 is driven to move after the bed board 311 is tilted, the protective structure 4 is raised from the patient's side to prevent the patient from falling out of bed, see Figure 3 , Figure 5 and Figure 6 Four buffer components 33 are arranged in a rectangular distribution on the upper end of the support plate 32. The two buffer components 33 on the same side are fixedly connected to the protective structure 4. The buffer component 33 includes a release head 331. The lower end of the release head 331 is fixedly connected to a connecting column 333. The lower end of the release head 331 is fixedly connected to a compression spring 332 fixedly connected to the upper end of the support plate 32. The inner surface of the connecting column 333 is rotatably connected to a gear 334. The rear part of the outer surface of the gear 334 is meshed with a rack 335 fixedly connected to the bottom wall of the inner cavity of the bed body 1.

[0032] Further, in order to realize that after the buffer assembly 33 follows the displacement of the support plate 32, the protective structure 4 is driven to move, refer to Figure 5 , Figure 6 and Figure 7 The inner surface of the gear 334 is wound with a cable 336, and one end of the cable 336 away from the gear 334 extends upward along the connecting column 333 and passes through the adjacent end surface of the support plate 32 to the inner side of the protective structure 4 and is fixedly connected to the protective structure 4; The protection structure 4 includes a protection assembly 41 that is slidably connected to the side wall of the support plate 32. The protection assembly 41 includes a protection plate 411 that is slidably connected to the side wall of the support plate 32 through a T-block. A slide groove 413 that is slidably connected to the T-block is provided on the side of the protection plate 411 close to the support plate 32. The end of the cable 336 that is away from the gear 334 passes through the T-block and extends to the inner surface of the slide groove 413 and is fixedly connected to the bottom wall of the inner surface of the slide groove 413. When one side of the bed board 311 is subjected to uneven force, the two release heads 331 on the same side will be pressed downward by the bed board 311. At this time, the connecting column 333 will move downward with the gear 334. While moving downward, the gear 334 will pull the cable 1 336 to move downward synchronously. However, in order to ensure the comfort of the patient, the rotation amplitude of the release head 331 should not be too large. Therefore, a rack 335 is provided to drive the gear 334 to rotate during the descending process of the gear 334. During this process, the cable 1 336 will gradually wrap around the axis of the cable 1 336, thereby driving the protective plate 411 to rise. Since the cable 1 336 is entangled while being pulled, the rising height of the protective plate 411 is much greater than the descending height of the gear 334. According to the actual bed height during use, the transmission ratio of the rack 335 and the gear 334 can be increased to achieve a larger rising ratio.

[0033] Embodiment 3: Based on embodiment 2, this embodiment further cooperates with the isolation guardrail 23 and the second cable 421. When it is necessary to get out of bed and retract the isolation guardrail 23, the isolation guardrail 23 is used to pull the second cable 421 to drive the slider 424 to slide in the installation groove 426 and the locking groove 412. During the sliding process of the slider 424, it will slide from the vertical part of the locking groove 412 into the horizontal part. At this time, the rising path of the protective plate 411 is blocked by the slider 424. Even if the bed board 311 is unevenly stressed due to the action of getting out of bed, at this time, under the traction of the protective plate 411 and the cable 1 336, the buffer assembly 33 cannot descend, and will provide support for the release head 331 to prevent it from rotating. At this time, the patient can get out of bed safely to avoid additional damage to the patient due to the anti-fall function, thereby improving the flexibility of equipment use and reducing the probability of patient injury.

[0034] Specifically, in order to lock the protection assembly 41 and prevent the protection assembly 41 from being offset due to uneven force on the bed board 311 during the process of getting out of bed, thereby causing the protection assembly 41 to rise from the bed body 1, refer to Figure 2 , Figure 8 , Fig. 9 and Fig.10A protection locking assembly 42 fixedly connected to the adjacent isolation guardrail 23 is provided on one side of the protection assembly 41 close to the inner wall of the bed body 1. The protection locking assembly 42 is arranged on the inner surface of the adjacent bed body 1. The protection locking assembly 42 includes a cable 421 fixedly connected to the adjacent isolation guardrail 23 and a mounting groove 426 opened on the inner surface of the bed body 1 close to the side of the isolation guardrail 23 on the same side. The cable 421 passes through the adjacent end surface of the bed body 1 and extends to the inner cavity of the mounting groove 426 and is forked front and back and is fixedly connected to sliders 424 respectively. The ends of the two sliders 424 close to each other are fixedly connected to compression springs 425. The ends of the two compression springs 425 close to each other are fixedly connected to a fixing block 422 fixedly connected to the inner surface of the mounting groove 426. The end of the mounting groove 426 close to the isolation guardrail 23 on the same side is provided with a limiting groove 423 slidably connected to the slider 424. The slider 424 is slidably connected to the horizontal part of the locking groove 412 and its width is equal to the width of the vertical part of the locking groove 412.

[0035] Further, in order to lock the protective plate 411 in accordance with the position change of the slider 424 in the locking groove 412, see Fig.10 Two locking grooves 412 are provided on one side of the protective plate 411 away from the support plate 32 and are slidably connected to the protective locking assembly 42. The locking groove 412 is L-shaped and its horizontal part is symmetrically distributed along the middle of the protective plate 411. The width of the horizontal part of the locking groove 412 is twice the width of the vertical part.

[0036] In order to facilitate patients getting in and out of bed and avoid injuries to patients caused by uneven force on the bed board 311 driving the protective structure 4 to move, it is necessary to restrict the protective board 411 during the process of getting in and out of bed; When the isolation guardrail 23 is in a downward vertical state, the second cable 421 will be pulled to move toward the outside of the bed body 1, and the sliders 424 on both sides will be pulled inward by the second cable 421. At this time, the sliders 424 will slide into the horizontal part of the locking groove 412, and the protective plate 411 will be restricted by the sliders 424 and cannot move upward; When the isolation guardrail 23 is in a vertical upward state, the slider 424 will be in the vertical part of the locking groove 412 under the action of the compression spring 425. At this time, the protective plate 411 slides upward, and the slider 424 slides in the vertical part of the locking groove 412 without affecting the movement of the protective plate 411.

[0037] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
