[0016] The present invention will be further described below in conjunction with the accompanying drawings:

[0018] Figure 2 It is a schematic diagram of the information collection module and foot rings worn on both feet;

[0020] Reference Figure 1 , Figure 2 and Figure 3 , the present invention is a monitoring device and a monitoring method for postoperative monitoring of lower limbs.

[0021] The monitoring device includes an information collection module, several sensors, a foot ring 3, a data processing center and a protection component. Figure 3 The information collection module obtains the parameters of several sensors in real time and sends them to the foot ring 3 as a relay station, and then the foot ring 3 sends the above parameters to the data processing center; after analysis, the data processing center determines whether the patient's movement is abnormal, and thus determines whether to start the protection component.

[0022] Let's talk about the sensor first. The sensor includes at least three pressure sensors 1 and at least two flexible deformation sensors 2. Each pressure sensor 1 is set under the foot to obtain the pressure of the sole, and each flexible deformation sensor 2 is set on the side of the foot to obtain the deformation of the skin. When three pressure sensors 1 are set, two pressure sensors 1 are located at the forefoot and one pressure sensor 1 is located at the heel.

[0023] The pressure sensor 1 can be set under the sole of the foot or on the bottom surface of the inside of the shoe or on the bottom surface of the outside of the shoe or in the insole. In the specific implementation, it is sufficient to ensure that the pressure sensor 1 can fully obtain the pressure parameters of the lower limbs. For the flexible deformation sensor 2, it needs to be attached to the foot; generally, a larger area of ​​tape is selected, and then the flexible deformation sensor 2 is fixed in the middle position of the tape, and finally the tape is attached to the skin, and the edges of the tape and the flexible deformation sensor 2 can all fit the skin. If the shoe can tightly wrap the foot, the flexible deformation sensor 2 can also be set on the side of the inside of the shoe, and then indirectly contact the skin of the foot.

[0024] For the information collection module, the main body is a printed circuit board, including a wired receiving module and a wireless transmitting module. The wired receiving module is connected to each sensor, and the wireless transmitting module is installed on the printed circuit board. The wireless transmitting module adopts 3G or 4G wireless communication mode, and accordingly, a connector for inserting a phone card or IC card is provided on the printed circuit board; other optional communication methods include Bluetooth connection. The information collection module needs to be small in size and then arranged at a position where the shoe is less deformed, so in this embodiment, it is arranged in the side interlayer on the inside of the shoe.

[0025] The foot ring 3 includes a body, a wireless receiving module and a wireless transmitting module are arranged in the body, and the wireless receiving module and the wireless transmitting module are arranged on a printed circuit board. The wireless receiving module receives the parameters sent by the information collection module, and the wireless transmitting module in the foot ring 3 sends these parameters out. Two ropes are arranged outside the body, and the two ropes are respectively provided with a first connecting member and a second connecting member. The first connecting member and the second connecting member are detachably connected so that the foot ring 3 can be detachably wrapped around the ankle.

[0026] The technical indicators of the foot ring 3 itself allow for an increase in its power and volume, facilitating long-distance signal transmission and precise control of protective components; and the foot ring 3 itself is convenient to conceal and easy to use.

[0027] Preferably, the first connector is a rectangular frame 4, and the second connector is a Velcro 5, but the same side of the second connector is provided with both a Velcro fleece surface and a Velcro thorn surface. When in use, the second connector passes through the frame 4 and then bends to wrap around a single side of the frame 4, and then the Velcro fleece surface is connected with the Velcro thorn surface to complete the connection between the first connector and the second connector. At this time, the foot ring 3 is detachably fixed to the ankle. In other embodiments, the first connector is a latch, and the second connector is a locking groove that can accommodate the latch, and the latch inserted into the locking groove can also complete the connection between the first connector and the second connector.

[0028] The data processing center receives the data sent by the foot ring 3 and determines the movement status of the lower limbs. The data processing center has to undertake the calculation task, which is generally a mobile communication device or a remote computer; a more convenient approach is to use both the mobile phone and the remote computer as the data processing center.

[0029] The monitoring method of the data processing center is as follows. When standing normally, each pressure sensor 1 simultaneously feeds back parameters; when lifting the foot, the parameter of the pressure sensor 1 at the heel position gradually becomes zero, and the parameter of the pressure sensor 1 at the forefoot position gradually increases and quickly becomes zero; when landing, the three pressure sensors 1 will all feed back parameters within 10ms; if a fall occurs, the above parameters change abnormally, and at this time the data processing center activates the electronic inflation valve to inflate the inflatable airbag, and at the same time the data processing center issues a rescue command.

[0030] Accompanied by medical staff, the patient walks, and the flexible deformation sensor 2 obtains multiple groups of change curves of the flexible deformation sensor 2 during the patient's normal walking process. The data processing center averages the above curves to form the change interval of the curve of the flexible deformation sensor 2 during the patient's normal walking process. When the patient stands and walks normally, each flexible deformation sensor 2 feedbacks parameters. When the above parameters deviate from the normal change interval, the data processing center activates the electronic inflation valve to inflate the airbag. Since the skin of different patients varies greatly, this solution is adopted to allow the data processing center to autonomously learn the change interval of the flexible deformation sensor 2. Of course, if the patient's walking style is very special, the pressure sensor 1 can also adopt this solution to allow the data processing center to autonomously learn the change interval of the pressure sensor 1.

[0031] Preferably, the data processing center generates a time-pressure change curve for each pressure sensor 1, and provides it to the patient or doctor for real-time viewing, analysis and adjustment of the treatment plan. During the recovery process, the pressure values ​​of the two soles gradually tend to be the same, indicating that the function has recovered well and the operation was successful.

[0032] As for the protective components. A group of protective components includes an inflatable airbag, a gas storage bottle and an electronic inflatable valve. When the electronic inflatable valve is in operation, it obtains gas from the gas storage bottle and then inflates the inflatable airbag. The electronic inflatable valve is wirelessly connected to the data processing center and is controlled to start and stop by the data processing center. Preferably, multiple groups of protective components are provided, and the inflatable airbags are respectively arranged in the patient's knees, hip sacrum or lumbar spine, which are important and prone to fracture areas.

[0033] Preferably, the gas cylinder contains high-pressure gas, such as carbon dioxide or other inert gas. As long as the electronic inflation valve is opened, the high-pressure gas can immediately fill the inflatable airbag, instantly forming an elastic protective layer to play a temporary protective role. Preferably, each inflatable airbag is equipped with a gas cylinder. The gas cylinder is made into an arc shape that can fit the body, which is convenient to wear or put into the interlayer of clothes.

[0034] Of course, the present invention is not limited to the above-mentioned embodiments, and the combination of different features of the above-mentioned embodiments can also achieve good results. Those skilled in the art can also make equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
