Description

Technical Field

[0001] This application relates to the field of medical care, specifically to a safety bed rail and bed for an ophthalmology ward. Background Technology

[0002] Bed rails are important safety devices in hospital wards, primarily used to prevent patients from falling out of bed, especially for children, the elderly, and patients with impaired consciousness. Particularly in ophthalmology wards, where patients undergoing eye treatment have limited vision, bed rails may become their primary means of support. Therefore, the structural design of bed rails significantly impacts patient convenience and safety.

[0003] However, the existing bed rail structure is relatively simple and still has many problems in actual use, especially safety issues. The height of the existing bed rails cannot be adjusted, which cannot effectively prevent children from climbing over or patients from falling out of bed. They also lack safety warning functions, and cannot take timely preventive measures when children climb over the bed rails or patients fall out of bed. Their limited functionality not only increases the risk of injury to patients, but also brings additional monitoring pressure to medical staff and family members. The safety protection effect needs to be improved. Utility Model Content

[0020] This application provides a bed for an ophthalmology ward, comprising:

[0021] A bed frame, wherein mounting grooves are provided on both sides of the bed frame;

[0022] The safety bed rail for the ophthalmology ward as described above is detachably installed in the mounting slot.

[0038] The technical solutions in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0039] Example 1

[0040] like Figure 1 and Figure 5 As shown, this embodiment provides a safety bed rail for an ophthalmology ward. The safety bed rail includes a crossbar 10 and a base 20. Multiple retractable vertical bars 30 are provided between the crossbar 10 and the base 20. The distance between the crossbar 10 and the base 20 can be adjusted. The retractable vertical bars 30 are passively extended or retracted as the distance between the crossbar 10 and the base 20 is adjusted, thereby realizing the adjustment of the height of the crossbar 10.

[0041] In this embodiment, the base 20 is detachably connected to the bed frame 70, and the safety bed rail is installed on the bed frame 70 through the base 20.

[0042] Preferably, the crossbar 10 and the base 20 can be arranged in parallel, and the telescopic vertical bar 30 is perpendicular to the crossbar 10 and the base 20. The number of telescopic vertical bars 30 can be freely set, as long as their spacing can achieve the protective function.

[0043] In this embodiment, at least two lifting mechanisms 40 are also provided between the crossbar 10 and the base 20. The lifting mechanisms 40 are parallel to the telescopic vertical bar 30, and the two ends of the lifting mechanisms 40 are respectively connected to the base 20 and the crossbar 10; Figure 1 As shown, two lifting mechanisms 40 are located on both sides of the telescopic vertical bar 30. The lifting mechanisms 40 are connected to the controller, and under the control of the controller, the lifting mechanisms 40 extend or retract to adjust the height of the horizontal bar 10.

[0044] In this embodiment, the retractable vertical bar 30 can be a two-bar structure, which can extend and retract through external force. The lifting mechanism 40 can be a screw drive mechanism, or a pneumatic or hydraulic telescopic mechanism. The external shape of the lifting mechanism 40 and the retractable vertical bar 30 can be similar, and they also serve as a railing.

[0045] It is worth mentioning that, in this embodiment, on the one hand, a sensing device 50 is provided on the upper surface of the crossbar 10, and the sensing device 50 is electrically connected to the controller. The sensing device 50 can be an infrared sensor or other spectral sensor. When an object, such as a human body, approaches the upper surface of the crossbar 10, the sensing device 50 can detect it and generate a corresponding first signal, which is then transmitted to the controller.

[0046] When the sensing device 50 of this embodiment generates a first signal, it indicates that at least one part of the patient is above the crossbar 10, and the patient may be climbing over the bed railing.

[0047] On the other hand, this embodiment also has a pressure sensing device 60, which is disposed between the horizontal bar 10 and the retractable vertical bar 30, and is used to detect the pressure on the horizontal bar 10. When the patient climbs over the horizontal bar 10, pressure will inevitably be applied to the horizontal bar 10. The pressure sensing device 60 generates a second signal in response to the pressure applied by the horizontal bar 10 to the retractable vertical bar 30; at this time, it indicates that the patient may have climbed over the bed rail.

[0048] Preferably, the pressure sensing device 60 can be a pressure sensor to detect the pressure on the crossbar 10 in real time.

[0049] This embodiment combines the functions of the aforementioned sensing device 50 and pressure sensing device 60. The lifting mechanism 40 is electrically connected to the sensing device 50 and pressure sensing device 60 respectively through a controller. When both of the above situations occur, that is, when the controller receives the first signal and the second signal at the same time, it can be determined that the patient is climbing over the bed rail. The controller responds to the first signal and the second signal to control the lifting mechanism 40 to extend, thereby increasing the height of the crossbar 10. The crossbar 10 is raised, preventing the patient from climbing over the bed rail and ensuring the patient's safety.

[0050] The safety bed rail in this ophthalmology ward automatically rises when a patient climbs over the rail, effectively preventing patients from falling out of bed. It is highly intelligent and particularly suitable for special scenarios such as ophthalmology wards, meeting the diverse needs of elderly and child patients and improving the safety and nursing efficiency of the ward.

[0051] As a further improvement, such as Figure 1 As shown, the sensing device 50 of this embodiment includes a plurality of sensing units 51. Each sensing unit 51 generates a warning signal in response to an object approaching the upper surface of the crossbar 10. The sensing device 50 generates a first signal in response to the number of warning signals being greater than a first preset value.

[0052] In the above embodiment, the sensing device 50 determines that the patient may climb over the bed rail when it detects a human body. Then, when the patient's hand touches the crossbar 10, it is also detected by the sensing device 50. However, the patient is not climbing over the bed rail, indicating normal handrail movement. In order to avoid such misjudgment, this embodiment is provided with multiple sensing units 51. Each sensing unit 51 generates a warning signal when it detects an object approaching the upper surface of the crossbar 10.

[0053] When a hand touches the crossbar 10, only one or two sensor units 51 may generate a warning signal. This situation does not constitute the state of climbing over the bed rail. If the patient climbs over the bed rail, with most of the patient's body above the crossbar 10, more sensor units 51 will inevitably generate warning signals. Therefore, a first preset value is set, which represents a quantity value, such as 4-6. When this condition is met, 4-6 warning signals are generated, indicating that the patient is climbing over the bed rail. Thus, the controller can accurately identify the patient climbing over the bed rail and immediately raise the crossbar 10 to prevent the crossbar 10 from being raised due to the patient touching it with one hand.

[0054] To ensure the detection effect of the sensing unit 51, multiple sensing units 51 are evenly spaced on the upper surface of the crossbar 10.

[0055] Similarly, the pressure exerted by a patient climbing over the bed rail and gripping the bed rail is different. In this embodiment, a second preset value is set, which is the pressure value exerted by the patient on the horizontal bar 10 when climbing over the bed rail. This value can be set to a portion of the patient's body weight, such as one-third of their body weight. When the patient applies pressure to the horizontal bar 10 with one hand, the pressure value detected by the pressure sensor 60 is less than the second preset value, and it is determined that there is no climbing over the bed rail. However, when the patient climbs over the bed rail, the pressure exerted by the patient on the horizontal bar 10 increases. When the pressure reaches the second preset value, the pressure sensor 60 generates a second signal, and the controller controls the horizontal bar 10 to rise, preventing the patient from climbing over the bed rail.

[0056] like Figure 2 As shown, a warning light 12 is provided on the crossbar 10 in this embodiment. The warning light 12 is electrically connected to the sensing device 50 and the pressure sensing device 60 via a controller. The warning light 12 provides warning feedback in response to a first signal or a second signal. When the patient climbs over the bed rail as described above, the warning light 12 will flash and sound an alarm as the crossbar 10 rises to alert the nursing staff.

[0057] Preferably, in one embodiment, the warning lights 12 are positioned at both ends of the horizontal bar 10 for easy observation.

[0058] like Figure 2 As shown, in this embodiment, a magnetic structure 22 is provided on the surface of the base 20. The magnetic structure 22 is used to be attracted and connected to the mating part 71 on the bed frame 70. The magnetic structure 22 is electrically connected to the controller and generates a third signal in response to the disconnection of the magnetic structure 22 and the mating part 71. The warning light 12 responds to the third signal and provides warning feedback.

[0059] The position of the magnetic structure 22 matches the position of the mating part 71 on the bed frame 70. When the base 20 of the bed rail and the bed frame 70 are in the normal installation position, the magnetic structure 22 and the mating part 71 are attracted to each other. When the base 20 and the bed frame 70 are not installed properly, the magnetic structure 22 and the mating part 71 are not attracted to each other. At this time, the bed rail is not installed properly, which poses a safety hazard, or the bed rail is moved, which poses a risk of tipping over. The warning light 12 will then flash to sound an alarm and alert the caregiver.

[0060] In this embodiment, the magnetic structure 22 can be a magnet, and the mating part 71 can be a magnetic material or a metal material that can be attracted by a magnet.

[0061] Specifically, such as Figure 4 and Figure 5 As shown, the magnetic suction structure 22 is disposed on the lower surface of the base 20. The magnetic suction structure 22 has a receiving cavity 223. A first conductor 221 and a second conductor 222 are disposed in the receiving cavity 223. The first conductor 221 and the second conductor 222 are elastic elements, such as metal springs. The first conductor 221 and the second conductor 222 are two components in the same circuit loop, which is electrically connected to the controller.

[0062] like Figure 4 As shown, the first conductor 221 and the second conductor 222 are not in contact under normal conditions. When the bed rail is not installed on the bed frame 70, or when the bed rail is not installed properly, the magnetic attraction structure 22 and the mating part 71 do not correspond in position, and the first conductor 221 and the second conductor 222 do not contact. The upper surface of the mating part 71 has a protrusion 711. When the magnetic attraction structure 22 and the mating part 71 do not correspond in position, the protrusion 711 cannot contact the first conductor 221.

[0063] like Figure 5 As shown, when the bed rail is installed on the bed frame 70, the magnetic structure 22 and the mating part 71 are aligned and attracted to each other. The protrusion 711 presses the first conductor 221, causing it to elastically deform and contact the second conductor 222. The first conductor 221 and the second conductor 222 form a circuit. In this embodiment, if the first conductor 221 and the second conductor 222 do not contact each other, the circuit is broken. The magnetic structure 22 generates a third signal based on this circuit break. The controller receives the third signal and controls the warning light 12 to work. The warning light 12 flashes to sound an alarm, alerting the caregiver that the bed rail is dangerous.

[0064] The controller mentioned in this embodiment includes a hardware infrastructure consisting of a central processing unit, non-volatile memory, and a bus system. The central processing unit interacts with the storage medium through an optimized bus timing protocol and executes the control program stored in the non-volatile memory, which includes the multiple steps described above. Since the use of the controller is common knowledge in the art, it will not be described in detail in this embodiment.

[0065] like Figure 1 and Figure 2 As shown, the lower surface of the crossbar 10 is provided with a first slide rail 11, and the upper surface of the base 20 is provided with a second slide rail 21. The two ends of the retractable vertical bar 30 are slidably connected to the first slide rail 11 and the second slide rail 21, respectively. The spacing between adjacent retractable vertical bars 30 is adjustable. By adjusting the spacing of the retractable vertical bars 30, the needs of different patient groups can be met. For example, for pediatric patients, the spacing of the retractable vertical bars 30 can be reduced to prevent pediatric patients from squeezing into the gaps between the retractable vertical bars 30, thus preventing falls from the bed.

[0066] In this embodiment, as Figure 1 As shown, a knob 31 is provided on the first slide rail 11 and / or the second slide rail 21. The knob 31 is connected to the telescopic vertical rod 30 and is used to fix the telescopic vertical rod 30 to the first slide rail 11 and / or the second slide rail 21. The knob 31 is used for adjustable fixing of the telescopic vertical rod 30. The knob 31 can adopt a threaded structure or other snap-fit ​​structure. This embodiment is not limited to only one.

[0067] In one embodiment, the base 20 and the crossbar 10 are arranged in parallel. The base 20 and the crossbar 10 are telescopic rod-shaped structures, and the base 20 and the crossbar 10 are two sleeved rod structures. The base 20 and the crossbar 10 are adjustable along their length, thereby realizing the length adjustment of the bed rail to meet the needs of people of different heights and improve the applicability of the bed rail.

[0068] Specifically, such as Figure 3 As shown, there are two crossbars 10. One end of one crossbar 10 is provided with a first extension 101, and the end of the other crossbar 10 is provided with a corresponding insertion hole. The first extension 101 is inserted into the insertion hole. The first extension 101 slides with the insertion hole and is relatively fixed by friction or a fastener. The length of the crossbar 10 is adjusted by the depth of the first extension 101 inserted into the insertion hole.

[0069] Similarly, two bases 20 are provided. One base 20 has a second extension 201 at one end, and the other base 20 has a corresponding insertion hole at its end. The second extension 201 can be slidably inserted into the insertion hole and is relatively fixed by friction or a fastener. The length of the base 20 is adjusted by the depth of the second extension 201 inserted into the insertion hole. The base 20 is adjusted synchronously with the crossbar 10.

[0070] In one embodiment, such as Figure 2 As shown, a light 13 is installed on the crossbar 10, and switches 14 are respectively installed on the lower surface of the crossbar 10 near both ends. The switches 14 are used to control the light 13. The switches 14 are located at the ends of the bed rails, so that the patient can easily reach and operate them, and the patient can access the switches from either end of the bed.

[0071] The design of the lighting lamp 13 meets the needs of patients getting up at night. The lighting lamp 13 can also be a sensor lamp that automatically turns on when it senses that the patient is getting up at night. The addition of the night lighting function makes it easier for patients to get up at night, reduces the risk of falls, and also reduces the night care burden of medical staff.

[0072] In one embodiment, the switches 14 at both ends of the crossbar 10 are also electrically connected to the controller. The lifting mechanism 40 responds to the control of the controller to lift and lower. The patient can manually control the switches 14 to raise or lower the bed rail to meet the patient's needs. Since the switches 14 are respectively set on the lower surface of both ends of the crossbar 10, the patient can access the switches 14 to operate them whether at the head or foot of the bed, which brings convenience to the patient.

[0073] In conclusion, the safety bed rail for ophthalmology wards in this embodiment not only prevents patients from climbing over the railings but also integrates multiple functions to meet the needs of children and the elderly. It addresses the shortcomings of existing bed rails in terms of safety, ease of use at night, and functional integration, making it particularly suitable for the elderly and children in special settings such as ophthalmology wards. This bed rail offers high safety, effectively preventing patients from falling out of bed and children from climbing over it; it is convenient for nighttime use, reducing the risk of falls through its lighting function; and it integrates bidirectional extension, lifting, and alarm functions to meet diverse needs, allowing patients and medical staff to quickly adjust the bed rail's position, effectively reducing the nursing burden on medical staff.
