[0031] It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.
[0032] In order to make the content of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
[0033] Embodiment 1
[0034] As Figures 1 to 6 shown, a patient out-of-bed reporting device using a sensor for detection includes a bed body 1. Grooves 4 are opened on both sides of the upper end of the bed body 1. An electric push rod 5 is installed inside the groove 4. A protective rod 6 is installed at the upper end of the electric push rod 5. When the electric push rod 5 extends, the protective rods 6 at both ends of the bed body 1 can prevent the patient from getting off the bed body 1 and can also prevent the patient from falling out of the bed. The control switch or remote control of the electric push rod 5 is controlled by the patient's family member or medical staff.
[0035] A cavity is formed inside the bed body 1, and the pressure detection structure 8 is arranged inside the cavity. A sponge pad 9 is installed at the upper end of the pressure detection structure 8. The pressure detection structure 8 includes a bottom plate 10, and a plurality of uniformly distributed air bags 18 are installed at the upper end of the bottom plate 10; a first spring 23 is installed inside the frame 22, a pressure sensor is installed inside the first spring 23, both ends of the first spring 23 are installed with sliding plates 24, the sliding plates 24 are located inside the frame 22, and the other ends of the sliding plates 24 are installed with sliding rods 25; an installation groove 26 is fixedly connected to the inside of the bottom plate 10, and one end of the sliding rod 25 is hinged to the installation groove 26; an inflation structure 21 is arranged on one side of the air bag 18. The inflation structure 21 includes a cylinder body 27, a slidable rubber plug 28 is installed inside the cylinder body 27, a connecting rod 29 is installed at one end of the rubber plug 28, the other end of the connecting rod 29 is fixedly connected to the air bag 18, an air inlet hole 31 is installed on the surface of the cylinder body 27, a pipeline 30 is installed on the surface of the cylinder body 27, and the other end of the pipeline 30 is connected to the air bag 18.
[0036] When the patient lies on the sponge pad 9, the sponge pad 9 transfers the pressure to the air bag 18. The air bag 18 squeezes towards both ends, thereby driving the sliding rod 25 to slide inside the frame 22, and then squeezing the first spring 23. When the pressure sensor installed inside the first spring 23 reaches the set value, it indicates that the patient is on the hospital bed. The hinge connection between the sliding rod 25 and the installation groove 26 can prevent the sliding rod 25 from getting stuck during the movement.
[0037] At the same time, the air bag 18 drives the connecting rod 29 to move. The movement of the connecting rod 29 drives the rubber plug 28 to move. The rubber plug 28 makes the inside of the cylinder body 27 in a negative pressure state, so that the air inside the air bag 30 enters the cylinder body 27 through the pipeline 30, and the air bag 18 is deflated, and balance adjustment can be carried out.
[0038] When the patient leaves the sponge pad 9, the pressure on the sponge pad 9 disappears. The air bag 18 drives the connecting rod 29 to move. The movement of the connecting rod 29 drives the rubber plug 28 to move. The rubber plug 28 makes the inside of the cylinder body 27 in a negative pressure state, so that the air inside the air bag 30 enters the cylinder body 27 through the pipeline 30, and the air bag 18 is inflated. The first spring 23 returns, the pressure sensor no longer reaches the predetermined value, and the alarm is broadcast.
[0039] The clamping assembly 2 is used to be fixed on the support rod at the lower end of the bed body 1. A vertical rod 3 is installed at one end of the clamping assembly 2, and a broadcast camera 7 is installed on the other side at the upper end of the vertical rod 3; the clamping assembly 2 includes: a cavity is installed inside the housing 11, two meshing gears 12 are rotatably installed inside the housing 11, and a first connecting rod 13 is connected to the center of the gear 12; one end of the second connecting rod 14 is hinged inside the housing 11; one end of the third connecting rod 15 is hinged to the other end of the first connecting rod 13, the other end of the second connecting rod 14 is hinged to the middle of the third connecting rod 15, and an arc-shaped clamping plate 16 is installed at the end of the third connecting rod 15 far from the first connecting rod 13. A motor is installed at the center of one of the gears 12.
[0040] The motor can control the rotation of gear 12, thereby driving the synchronous rotation of two meshing gears, further driving the rotation of link 13, the synchronous rotation of link 14, and further driving the rotation of link 15, so that the two arc-shaped clamping plates 16 can move away from or close to each other. When it is necessary to adjust the position of the clamping assembly 2, pressing the button on the upper end of the housing 11 to control the motor to start can control the opening and closing of the clamping assembly 2, thereby adjusting the position of the broadcast camera 7 for convenient use. A call device 32 is installed at the head of the bed body 1 for the patient to use to call the nurse to assist in getting out of bed.
[0041] Embodiment 2
[0042] When the patient lies on the sponge pad 9, the sponge pad 9 transfers the pressure to the airbag 18, and the airbag 18 squeezes towards both ends, thereby driving the sliding rod 25 to slide into the frame body 22, and further squeezing the first spring 23. When the pressure sensor installed inside the first spring 23 reaches the set value, it indicates that the patient is in the hospital bed. The hinge connection between the sliding rod 25 and the installation groove 26 can prevent the sliding rod 25 from getting stuck during the movement.
[0043] At the same time, the airbag 18 drives the connecting rod 29 to move, the movement of the connecting rod 29 drives the rubber plug 28 to move, and the rubber plug 28 makes the inside of the cylinder body 27 in a negative pressure state, so that the air inside the airbag 30 enters the cylinder body 27 through the pipeline 30 to deflate the airbag 18, and balance adjustment can be carried out.
[0044] When the patient leaves the sponge pad 9, the pressure on the sponge pad 9 disappears. At the same time, the airbag 18 drives the connecting rod 29 to move, the movement of the connecting rod 29 drives the rubber plug 28 to move, and the rubber plug 28 squeezes the air inside the cylinder body 27 so that the air enters the airbag 18 through the pipeline 30 to inflate the airbag 18, which can keep the airbag 18 at a certain volume, and thus enable the sliding of the sliding rod 25.
[0045] The motor can control the rotation of gear 12, thereby driving the synchronous rotation of two meshing gears, further driving the rotation of link 13, the synchronous rotation of link 14, and further driving the rotation of link 15, so that the two arc-shaped clamping plates 16 can move away from or close to each other. When it is necessary to adjust the position of the clamping assembly 2, pressing the button on the upper end of the housing 11 to control the motor to start can control the opening and closing of the clamping assembly 2, thereby adjusting the position of the broadcast camera 7 for convenient use. A call device 32 is installed at the head of the bed body 1 for the patient to use to call the nurse to assist in getting out of bed.
[0046] The electrical components appearing in this article are all electrically connected to the external main controller and the 220V mains power supply.
