Description

Technical Field

[0001] This utility model relates to the field of medical and nursing equipment technology, specifically a retractable anti-fall bed rail. Background Technology

[0002] Elderly patients with hip fractures often have multiple chronic diseases, and the incidence of postoperative delirium is as high as 15%-40%. Delirium causes confusion and agitation, increasing the risk of falls from bed by 3-6 times compared to ordinary patients (fall rate 10%-30% in delirious patients, 5%-10% in non-delirious patients). Falls from bed not only cause serious injuries such as secondary fractures and intracranial hemorrhage, but also prolong the rehabilitation period and increase medical costs.

[0003] Bed rails are a common physical safety device used in hospitals to prevent falls from bed. Currently, two main types of bed rails are used clinically: 1. Traditional stainless steel bed rails: These bed rails are usually fixed structures, about 93cm long, and can only be installed in the middle of the bed. There is no effective protection in the approximately 50cm area at the head and foot of the bed. For patients with active delirium or those who are thin, they are very likely to roll out of the head or foot of the bed at night and fall out of bed, posing a serious safety hazard.

[0004] 2. Folding bed rails: Although this type of structure improves the length coverage, it is usually reinforced with screws and other connectors, resulting in poor structural stability. Delirium patients often pull or slap the rails forcefully during an attack, which can easily cause them to loosen or even break, increasing the risk of falling out of bed.

[0005] In summary, existing bed rail structures generally suffer from problems such as non-adjustable protection range and inconvenient operation, putting medical staff in a dilemma between "nursing efficiency" and "safety assurance." Therefore, there is an urgent need for a bed rail device that is structurally stable, adjustable in length, and easy to operate, in order to improve the protection level of postoperative delirium patients. Utility Model Content

[0006] In response to the problems raised in the background art, the present invention aims to provide a retractable improved bed rail. This device features adjustable structure, safe limiting, and convenient operation, which can effectively improve the nighttime protection of delirium patients and reduce the occurrence of bed falls.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A retractable anti-fall bed rail includes a main frame, which includes an upper first horizontal tube, a lower second horizontal tube, and at least two uprights. The first horizontal tube, the second horizontal tube, and the at least two uprights form a rectangular frame structure. At least two fixed plug-in parts are installed at the lower part of the main frame and are connected to the bed body. The main frame is provided with sub-frames at its left and right ends, which can move along the length of the first horizontal tube. Each sub-frame is slidably connected to the main frame, and each sub-frame has a limiting hole. The left and right halves of the main frame are respectively provided with limiting devices corresponding to the sub-frames on the same side. The limiting device includes a first positioning mechanism and a second positioning mechanism, wherein the distance from the first positioning mechanism to the center of the main frame is greater than the distance from the second positioning mechanism to the center of the main frame; The first positioning mechanism includes a first straight spring switch and a first spring pin. The head A of the first spring pin is provided with an inclined surface. When the limiting hole of the corresponding sub-frame moves to the position of the first positioning mechanism, the head A of the first spring pin is inserted into the limiting hole of the corresponding sub-frame under the action of spring A and prevents the sub-frame from disengaging from the main frame. The first spring pin is locked by the first straight spring switch and does not reset. The second positioning mechanism includes a second key spring switch and a second spring pin. The head B of the second spring pin is spherical. When the limiting hole of the corresponding sub-frame moves to the position of the second positioning mechanism, the head B of the second spring pin is inserted into the limiting hole of the corresponding sub-frame under the action of the spring B, and the second spring pin is locked by the second key spring switch to prevent it from resetting.

[0008] The subframe includes a first insertion tube, a second insertion tube, and an arc-shaped bend. One end of the first insertion tube is inserted into the first horizontal tube and slidably connected to it. The other end of the first insertion tube is connected to one end of the second insertion tube via the arc-shaped bend. The other end of the second insertion tube is inserted into the second horizontal tube and slidably connected to it. The limiting hole is provided on the first insertion tube. Each end of the first horizontal tube is provided with a set of pin holes. Each set of pin holes includes a first pin hole and a second pin hole. The first pin hole is slidably connected to the first spring pin of the first positioning mechanism on the same side, and the second pin hole is slidably connected to the second spring pin of the second positioning mechanism on the same side.

[0009] The first positioning mechanism further includes a first housing, which is fixedly mounted on the first horizontal tube and located at the first pin hole. The inner cavity of the first housing and the outer circumferential surface of the first horizontal tube have a first cavity. The first cavity is provided with a first horizontal partition, and the first horizontal partition has a first through hole in the middle. The first spring pin includes a head A, a handle A, a boss A, and a spring A. The head A and the handle A are fixedly connected through the boss A. The head A is slidably connected to the first pin hole, and the lower end of the head A is set as an inclined surface. The upper end of the handle A passes through the first through hole, and the spring A is sleeved on the handle A. The upper end of the spring A abuts against the first horizontal partition, and the lower end abuts against the boss A. The top wall of the first cavity is provided with a second through hole. A first straight-button spring switch is installed in the second through hole. The outer shell A of the first straight-button spring switch is fixedly connected to the second through hole, and the moving contact A of the first straight-button spring switch is located at the upper opening of the first through hole.

[0010] The second positioning mechanism further includes a second housing, which is fixedly installed on the first horizontal tube and located at the second pin hole. The inner cavity of the second housing and the outer circumferential surface of the first horizontal tube have a second cavity. A second horizontal partition is provided inside the second cavity, and a third through hole is provided in the middle of the second horizontal partition. The second spring pin includes a head B, a handle B, a boss B, and a spring B. The head B and the handle B are fixedly connected through the boss B. The head B is slidably connected to the second pin hole. The lower end of the head B is spherical. The upper end of the handle B passes through the third through hole. The spring B is sleeved on the handle B. The upper end of the spring B abuts against the second horizontal partition, and the lower end abuts against the boss B. A fourth through hole is provided on the top wall of the second cavity. A second straight spring switch is installed in the fourth through hole. The outer shell B of the second straight spring switch is fixedly connected to the third through hole. The moving contact B of the straight spring switch is located at the upper opening of the second through hole.

[0011] The main frame also includes a guide tube, which is fixed between the first horizontal tube and the second horizontal tube; the sub-frame also includes a third insertion tube, which is located between the first insertion tube and the second insertion tube, with one end of the third insertion tube fixedly connected to the arc-shaped bend tube and the other end slidably connected to the guide tube.

[0012] This utility model has the following beneficial effects: It is applicable to nursing beds for elderly patients with delirium after hip fracture surgery, addressing the dual shortcomings of insufficient protection range of traditional bed rails and poor stability of folding guardrails, thus improving patient safety and nursing convenience. The retractable bed rails provided by this utility model add a sliding subframe, a limiting device, and a guiding compensation structure to the original traditional bed rail structure, allowing the length of the bed rails to be adjusted according to actual nursing needs. Both the first and second positioning mechanisms of this utility model have easy-to-operate anti-slip and locking functions. During the day, the bed rails can be retracted to a shorter section for family care; at night, the bed rails can be extended to cover the entire length of the bed, increasing the protection range. The limiting device ensures stable positioning during adjustment, preventing accidental sliding or derailment. Attached Figure Description

Detailed Implementation

[0020] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1-6 As shown, this utility model discloses a retractable anti-fall bed rail, including a main frame 1. The main frame 1 includes an upper first horizontal tube 101, a lower second horizontal tube 102 and at least two uprights 103. The first horizontal tube 101, the second horizontal tube 102 and the at least two uprights 103 form a rectangular frame structure. At least two fixed plug-in parts 104 are installed at the lower part of the main frame 1 and are connected to the bed body. The main frame 1 is provided with sub-frames 2 at its left and right ends, which can move along the length of the first horizontal tube 101. Each sub-frame 2 is slidably connected to the main frame 1, and each sub-frame 2 has a limiting hole. The left and right halves of the main frame 1 are respectively provided with limiting devices 3 corresponding to the sub-frames on the same side; the limiting device 3 includes a first positioning mechanism 31 and a second positioning mechanism 32, and the distance from the first positioning mechanism 31 to the center of the main frame 1 is greater than the distance from the second positioning mechanism 32 to the center of the main frame 1; The first positioning mechanism 31 includes a first straight spring switch 312 and a first spring pin 311. The head A 3111 of the first spring pin 311 is provided with an inclined surface. When the limiting hole of the corresponding sub-frame 2 moves to the position of the first positioning mechanism 31, the head A 3111 of the first spring pin 311 is inserted into the limiting hole of the corresponding sub-frame 2 under the action of the spring A 3114 and prevents the sub-frame 2 from disengaging from the main frame. The first straight spring switch 312 locks the first spring pin 311 and prevents it from resetting. The second positioning mechanism 32 includes a second key spring switch 322 and a second spring pin 321. The head B 3211 of the second spring pin 321 is spherical. When the limiting hole of the corresponding sub-frame 2 moves to the position of the second positioning mechanism 32, the head B 3211 of the second spring pin 321 is inserted into the limiting hole of the corresponding sub-frame 2 under the action of the spring B 3214, and the second spring pin 321 is locked by the second key spring switch 322 to prevent it from resetting.

[0022] In the above structure, the first straight-button spring switch 312 and the second straight-button spring switch 322 are both existing technologies. Their specific structures can be referred to as those of a press-type ballpoint pen, and will not be described in detail here.

[0023] The method of using this utility model is as follows: When no one is available to care for you at night, extend the bed rails so that they cover the entire length of the bed; at this time, hold the arc-shaped bend 204 of the sub-frame 2 and pull the sub-frame 2 outward until the limiting hole on the first insertion tube 201 moves to the position of the first positioning mechanism 31; the inclined surface of the head A3111 of the first spring pin 311 automatically inserts into the limiting hole under the action of the spring A3114, and then press the first straight spring switch 312. The moving contact A3121 of the first straight spring switch 312 extends downward and locks, pressing the first spring pin 311 to prevent the patient from accidentally pushing the sub-frame 2 into the main frame at night, causing the risk of falling out of bed. When someone is providing care during the day, retract the bed rails. At this time, press the first linear spring switch 312 to reset the moving contact A3121 of the first linear spring switch 312, releasing the lock on the first spring pin 311. Then push the sub-frame 2 inward to move the limiting hole to the position of the second positioning mechanism 32. When a "click" sound is heard, the spherical surface of the head B3211 of the second spring pin 321 is inserted into the limiting hole under the action of the spring B3214. Press the second linear spring switch 322 to lock the position, making it convenient for family members to perform bedside care operations.

[0024] The innovation of this utility model lies in the fact that both the first positioning mechanism 31 and the second positioning mechanism 32 have easy-to-operate anti-disengagement and locking functions. The inclined surface of the head A3111 of the first spring pin 311 can prevent the sub-frame 2 from detaching from the main frame 1 when pulled outward; when the sub-frame 2 is pulled out to the correct position, pressing the first straight spring switch 312 will cause the moving contact A3121 of the first straight spring switch 312 to extend downward and lock the head A3111 of the first spring pin 311 so that it does not reset, which can prevent the sub-frame 2 from retracting due to unconscious pulling action when the patient's condition occurs, thus improving safety.

[0025] The subframe 2 includes a first insertion tube 201, a second insertion tube 202, and an arc-shaped bend tube 204. One end of the first insertion tube 201 is inserted into the first horizontal tube 101 and slidably connected to the first horizontal tube 101.

[0027] The second positioning mechanism 32 further includes a second housing 323, which is fixedly installed on the first horizontal tube 101 and located at the second pin hole 112. The inner cavity of the second housing 323 and the outer peripheral surface of the first horizontal tube 101 have a second cavity. A second horizontal partition 324 is provided inside the second cavity, and a third through hole is provided in the middle of the second horizontal partition 324.
