DETAILED DESCRIPTION

[0024] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0025] Example 1

[0026] like Figure 1 to Figure 4 As shown, Example 1 discloses an alarm system for preventing patients from getting out of bed on their own and accidentally falling out of bed, which is mainly composed of an upper rotating rod 1, a lower rotating rod 2, an upper hinge 3, a lower hinge 4, an upper restraint 5, a lower restraint 6 and an alarm device.

[0027] like Figure 1 to Figure 4 As shown, the upper rotating rod 1 is used to be abutted against the patient's lower thigh near the knee joint, and the upper rotating rod 1 is provided with an upper restraint 5 for fixing it to the patient's thigh; the lower rotating rod 2 is used to be abutted against the patient's upper calf near the knee joint, and the lower rotating rod 2 is provided with a lower restraint 6 for fixing it to the patient's calf; the lower end of the upper rotating rod 1 is fixedly connected to the upper hinge 3, and the lower end of the outer side surface of the upper hinge 3 is provided with a circular connecting column 3a, the upper end of the lower rotating rod 2 is fixedly connected to the lower hinge 4, and the upper end of the inner side surface of the lower hinge 4 is provided with a connecting cavity 4a, and the circular connecting column 3a is embedded in the connecting cavity 4a and can rotate relatively.

[0028] like Figure 2 , Figure 3 As shown, the alarm device is mainly composed of a power supply 7, an alarm element 8, a first contact piece 9, a second contact piece 10 and a switch contact piece 11. The power supply 7 and the alarm element 8 are installed in the lower hinge 4. The first contact piece 9 and the second contact piece 10 are respectively arranged on the inner wall surface of the connecting cavity 4a. A gap is left between the first contact piece 9 and the second contact piece 10. One end of the power supply 7 is connected to the first contact piece 9, and the other end is connected to the alarm element 8. The other end of the alarm element 8 is connected to the second contact piece 10. The switch contact piece 11 is arranged on the outer peripheral surface of the circular connecting column 3a. When the angle between the lower hinge 4 and the upper hinge 3 is less than the set angle, the first contact piece 9 and the second contact piece 10 can be connected and conducted through the switch contact piece 11.

[0029] During specific use, the upper rotating rod 1 is placed against the patient's lower thigh near the knee joint and fixed with the upper restraint 5, and the lower rotating rod 2 is placed against the patient's upper calf near the knee joint and fixed with the lower restraint 6; when the patient is in bed, his or her calf is generally in a straight or slightly bent state, and the angle between the thigh and the calf is basically slightly less than 180 degrees, and will not be less than the set angle. At this time, the first contact piece 9 and the second contact piece 10 cannot be connected and conducted. When the patient gets out of bed privately, his or her calf will bend to a position close to 90 degrees due to gravity and the need to stand. At this time, the angle between the thigh and the calf will be less than the set angle, and the first contact piece 9 and the second contact piece 10 will be connected and conducted through the switch contact piece 11, and the alarm element 8 will be energized and send out an alarm signal.

[0030] In the present invention, the set angle can be 90 to 120 degrees, which is based on the angle that the patient's calf must be bent at when getting out of bed. The change of the set angle can be achieved by changing the gap between the first contact piece 9 and the second contact piece 10 and changing the length of the switch contact piece 11.

[0031] like Figure 1 As shown, in this embodiment 1, the upper restraint 5 includes a first elastic belt 5.1, a first plug 5.2 and a first buckle 5.3, the middle part of the first elastic belt 5.1 is fixedly connected to the upper rotating rod 1, one end of the first elastic belt 5.1 is fixedly connected to the first plug 5.2, and the other end is fixedly connected to the first buckle 5.3. The lower restraint 6 includes a second elastic belt 6.1, a second plug 6.2 and a second buckle 6.3, the middle part of the second elastic belt 6.1 is fixedly connected to the lower rotating rod 2, one end of the second elastic belt 6.1 is fixedly connected to the second plug 6.2, and the other end is fixedly connected to the second buckle 6.3.

[0032] like Figure 1 As shown, in this embodiment 1, a circular cavity 3b is provided at the lower end of the outer side surface of the upper hinge 3, the circular connecting column 3a is arranged at the center of the circular cavity 3b, and an arc-shaped opening 3c is provided on the peripheral wall of the circular cavity 3b for the lower hinge 4 to extend into. In this way, the arc-shaped opening 3c can limit the relative rotation angle between the lower hinge 4 and the upper hinge 3 by the size of its opening, so that the user can clearly distinguish the wearing direction of the product.

[0033] like Figure 1 As shown, in this embodiment 1, the upper hinge 3 and the lower hinge 4 are both made of engineering plastics, the outer peripheral wall of the circular connecting column 3a is provided with an arc-shaped boss 3d bulging outward, and the inner peripheral wall of the connecting cavity 4a is provided with an arc-shaped groove 4b sunken inward. With such a configuration, when the upper hinge 3 and the lower hinge 4 are assembled, the circular connecting column 3a can be squeezed into the connecting cavity 4a under pressure, and the arc-shaped boss 3d on the outer peripheral wall of the circular connecting column 3a and the arc-shaped groove 4b on the inner peripheral wall of the connecting cavity 4a form a limiting structure, so that the circular connecting column 3a cannot be disengaged from the connecting cavity 4a, thereby making the product easy to install and reducing the manufacturing cost.

[0034] In this embodiment 1, the alarm element 8 can be a conventional product in the prior art, including but not limited to a light alarm, a sound alarm, a vibration alarm, etc. The power source 7 preferably uses a button battery, which is convenient to disassemble and replace. Of course, the power source 7 can also use a rechargeable battery.

[0035] Example 2

[0036] like Figure 5 to Figure 7As shown, Example 2 discloses an alarm system for preventing a patient from getting out of bed by himself and accidentally falling out of bed, which differs from Example 1 as follows:

[0037] like Figure 5 to Figure 7 As shown, in this embodiment 2, the upper rotating rods 1 have two, and the two upper rotating rods 1 are arranged in parallel, respectively used to be close to the inner and outer sides of the patient's thigh, and the lower end of each upper rotating rod 1 is connected to an upper hinge 3, and the upper ends of the two upper rotating rods 1 are commonly connected to the upper restraint 5; the lower rotating rods 2 have two, and the two lower rotating rods 2 are arranged in parallel, respectively used to be close to the inner and outer sides of the patient's calf, and the upper end of each lower rotating rod 2 is connected to a lower hinge 4, and the lower ends of the two lower rotating rods 2 are commonly connected to the lower restraint 6. Such an arrangement can make the upper rotating rods 1 and the lower rotating rods 2 closer to the patient's legs, thereby improving accuracy.

[0038] like Figure 5 to Figure 7 As shown, in this embodiment 2, the upper restraint 5 includes a first elastic belt body 5.1, a first plug 5.2, a first buckle 5.3 and an upper arc hoop 5.4, the upper ends of the two upper rotating rods 1 are respectively fixedly connected to the two ends of the upper arc hoop 5.4, and the two ends of the upper arc hoop 5.4 are respectively connected to a first elastic belt body 5.1, and the other ends of the two first elastic belt bodies 5.1 are respectively connected to the first plug 5.2 and the first buckle 5.3; the lower restraint 6 includes a second elastic belt body 6.1, a second plug 6.2, a second buckle 6.3 and a lower arc hoop 6.4, the upper ends of the two lower rotating rods 1 are respectively fixedly connected to the two ends of the lower arc hoop 6.4, and the two ends of the lower arc hoop 6.4 are respectively connected to a second elastic belt body 6.1, and the other ends of the two second elastic belt bodies 6.1 are respectively connected to the second plug 6.2 and the second buckle 6.3. Such arrangement makes the upper restraint member 5 and the lower restraint member 6 have better shape stability and higher fixing performance, greatly reducing the probability of the product moving around the legs, and improving the practicality of the product. In actual use, the upper arc hoop 5.4 and the lower arc hoop 5.4 are preferably installed against the rear side of the thigh and calf, so that the restraint performance is better.

[0039] like Figure 5 to Figure 7As shown, in this embodiment 2, the lower surfaces of the two ends of the upper arc hoop 5.4 are provided with upper connecting parts 5.4a extending downward, and the upper connecting parts 5.4a are provided with upper plug holes 5.4b, and the upper end of the upper rotating rod 1 is inserted into the upper plug holes 5.4b and fastened with screws, and the lower end of the upper rotating rod 1 is also plugged and connected with the upper hinge 3; the upper surfaces of the two ends of the lower arc hoop 6.4 are provided with lower connecting parts 6.4a extending upward, and the lower connecting parts 6.4a are provided with lower plug holes 6.4b, and the upper end of the lower rotating rod 2 is inserted into the lower plug holes 6.4b and fastened with screws, and the upper end of the lower rotating rod 2 is also plugged and connected with the lower hinge 4. In this way, the upper rotating rod 1 and the lower rotating rod 2 can be disassembled and replaced to adapt to the use of patients with different body shapes.

[0040] In this embodiment 2, the alarm element 8 is a wireless signal sending module, and the alarm device also includes a monitoring host and a wireless signal receiving module. The monitoring host is set in the nurse station, and the wireless signal receiving module is installed in the monitoring host. The wireless signal receiving module can communicate with the wireless signal sending module. This arrangement allows the alarm signal to be directly transmitted to the nurse station, which allows nurses to discover and stop it in time on the one hand, and avoids the traditional alarm signal [sound, light] from interfering with the rest of other patients on the other hand.

[0041] In this embodiment 2, the wireless signal sending module and the wireless signal receiving module can adopt conventional products in the prior art, such as a Bluetooth module, a WiFi module, a Zigbee module, etc., and the monitoring host can adopt a conventional PC.

[0042] The above description is only a preferred embodiment of the present invention, and the above specific embodiment is not intended to limit the present invention. Various deformations and modifications may occur within the scope of the technical concept of the present invention, and any modification, modification or equivalent replacement made by a person of ordinary skill in the art based on the above description shall fall within the scope of protection of the present invention.
