Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to an anti-fall reminder device. Background Art

[0002] Elderly patients over 65 years old are at high risk of falling. Some elderly people are unwilling to accept old age, are unwilling to trouble others, or have stubborn personalities. Even when nurses repeatedly persuade them to inform their caregivers or nurses before leaving the bed at night, they still leave the bed alone to go to the toilet at night, which increases the risk of falling. Especially at night, there are few staff on duty, many high-risk patients who need to be patrolled, and nursing staff cannot promptly and effectively discover patients leaving the bed without permission. The incidence of falling after leaving the bed at night is higher. Existing alarm devices are usually fixed on the hospital bed and can only remind the accompanying family members by sound. They cannot notify medical staff to assist the patient to get out of bed as soon as the patient leaves the bed to avoid the patient falling when getting out of bed on his own, which leads to missing the best rescue time and causing serious harm to the patient.

In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0022] Combine the following Figure 1 to Figure 4 The utility model is described in detail.

[0023] Example:

[0024] A fall prevention reminder device, in some embodiments, includes a first shell 1 and a second shell 2, wherein a controller 3 is provided inside the first shell 1, and an infrared sensor 4 electrically connected to the controller 3 is also provided inside the first shell 1, and a signal transmitting end 5 of the infrared sensor 4 is arranged on one side of the first shell 1; one side of the first shell 1 is also provided with a fixing mechanism for fixing to the side of a bed, and the fixing mechanism is arranged on a side adjacent to the signal transmitting end 5; a pressing mechanism for pressing an emergency notification button 6 is provided on the second shell 2, and the pressing mechanism is driven by a motor 7, and the motor 7 is electrically connected to the controller 3 through a line; the second shell 2 is connected to the wall of the ward through a detachable structure.

[0025] When in use, first install the first shell 1 to the side of the bed near the head of the bed through a fixing mechanism, and make the signal transmitting end 5 of the infrared sensor 4 face the foot of the bed, and install the second shell 2 to the wall of the bed through a detachable structure, and make the pressing mechanism installed to the corresponding position of the emergency notification button 6. When resting at night, the medical staff turns on the device and the device starts working; at night, when the elderly patient leaves the bed without permission, the patient sits on the side of the bed and stretches his feet under the bed, the infrared sensor 4 detects the human body signal, thereby turning on the motor 7 so that the pressing mechanism presses the emergency notification button 6, and then notifies the nurse on duty on the rescue desk to get the news as soon as possible, and then quickly arrives at the ward to assist the patient. This device can notify medical staff to provide rescue as soon as the patient leaves the bed, avoiding missing the best rescue time and causing serious harm to the patient.

[0026] It is worth mentioning that the infrared sensor 4 is preferably an active infrared sensor, and the sensing distance is not more than two meters and not less than one and a half meters.

[0027] In some embodiments, the fixing mechanism comprises a magnet patch with an L-shaped cross section, and the L-shaped magnet patch 8 matches with the bottom end of the bedside 9. The magnet patch facilitates the installation and removal of the first housing 1.

[0028] In some embodiments, the motor 7 is arranged inside the second shell 2 and fixedly connected thereto, and the pressing mechanism includes a driving disk 10 fixedly connected to the output end of the motor 7, and a cylindrical pin 11 is fixedly connected to the surface of the driving disk 10, and the cylindrical pin 11 is eccentrically arranged with the driving disk 10; the second shell 2 is rotatably connected to a receiving disk 13 through a rotating pin 12, and the receiving disk 13 is provided with a driving groove 14 having an opening communicating with the outside, and the driving groove 14 cooperates with the cylindrical pin 11; a torsion spring 15 is sleeved on the outer side of the rotating pin 12, one end of the torsion spring 15 is fixedly connected to the rotating pin 12, and the other end is fixedly connected to the inner wall of the second shell 2; one end of the rotating pin 12 is arranged on the outside of the second shell 2 and is connected to a pressing block 16.

[0029] During specific use, when the motor 7 is turned on so that the pressing mechanism presses the emergency notification button 6, the motor 7 drives the driving disk 10 to rotate, so that the cylindrical pin 11 enters the driving slot 14 from the opening, and then drives the rotating pin 12 to rotate, so that the pressing block 16 flips downward to press the emergency notification button 6, thereby notifying the nurse; then the driving disk 10 continues to rotate, so that the cylindrical pin 11 disengages from the driving slot 14 again, and at this time the rotating pin 12 rotates back to its position under the action of the torsion spring 15, so that the driving slot 14 returns to its position, and then the driving disk 10 rotates one circle and re-enters the driving slot 14, so that the pressing block 16 presses the emergency notification button 6 again until the nurse arrives and turns off the motor 7.

[0030] In some embodiments, a power module 17 is provided in each of the first shell 1 and the second shell 2; the power module 17 in the first shell 1 is electrically connected to the controller 3 and the infrared sensor 4, respectively, and the power module 17 in the second shell 2 is electrically connected to the motor 7. In this embodiment, the power module 17 is used to provide power.

[0031] In some embodiments, the top of the first shell 1 is connected to a pad 19 via a flexible connecting belt 18 , and a pressure sensor 20 electrically connected to the controller 3 is disposed in the pad 19 .

[0032] When in use, after the first housing 1 is fixed, the pad 19 is placed under the patient's pillow 24. When the patient rests at night, the head rests on the pillow 24. At this time, the pressure sensor 20 feels the pressure, and the controller 3 determines that it is in a normal state; when the patient leaves the bed without permission, the pressure sensor 20 does not feel the pressure, and the device enters a warning state; when the patient sits up from the bed and prepares to leave the bed, the patient's feet are detected by the infrared sensor, so that the pressing mechanism presses the emergency notification button 6 to notify the nurse. Through this technical feature, the detection accuracy of the device can be improved and the probability of accidental touch of the device can be reduced.

[0033] In some embodiments, a switch 21 connected to the motor 7 is disposed on the second housing 2 .

[0034] During specific use, the nurse turns off the motor 7 through the switch 21 to prevent the alarm from continuing.

[0035] In some embodiments, the detachable structure includes a slot 22 fixedly connected to the wall of the ward, and an outer surface of the second shell 2 is provided with a plug plate 23 that matches the slot 22.

[0036] During specific use, a slot 22 is installed in advance on the ward wall of each bed's corresponding emergency notification button 6. When the bed is for a high-risk group of falling, the second shell 2 and the first shell 1 are installed.

[0037] It is worth mentioning that the controller 3 is a prior art and can adopt a commonly used PLC, such as S7-300.

[0038] The above-mentioned embodiments only express the specific implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the protection scope of the present application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the technical solution concept of the present application, and these all belong to the protection scope of the present application.
