The beneficial effects of the intelligent walking aid and the system applied to the walking aid of the present invention are as follows:

1. The present invention monitors the tilting angle of the walker itself through the posture detection module inside the intelligent control console. In this way, when the walker is not tilted seriously, the intelligent control console can give prompts in time; and when a serious tilt occurs, the tilting information can be transmitted to the nurse station through the WIFI transmission module, and the nurses at the nurse station can take rescue actions;

2. The present invention allows the patient to actively switch and adjust the damping of the damping wheel. In this way, when the patient needs to rest, he only needs to adjust the damping to the maximum, so that the walker is difficult to slide by itself. When the patient needs to perform thrust training, he only needs to perform targeted damping training of different levels.

3. The present invention monitors the patient's blood oxygen and pulse rate through a blood oxygen monitoring module, and uploads the monitoring results to the nurse station of the corresponding department, so that the nurses and doctors of the corresponding department can make accurate judgments to determine whether the patient needs to continue exercising.

4. The present invention integrates a positioning module on the intelligent console. The positioning module cooperates with the internal GPS positioning system and Bluetooth/LORA positioning. In indoor conditions, the specific department location of the equipment can be determined by Bluetooth/LORA positioning, and in outdoor environments, its location can also be determined by the GPS positioning system.

5. The intelligent console automatically adjusts the resistance and speed according to the feedback values during driving through posture detection, resistance feedback and speed feedback.

As shown in Fig. 1-2, according to one aspect of the present invention, there is provided an intelligent walker, comprising a frame 1 and a handbrake 9. When the walker is in parking mode, especially when the patient is sitting and resting, the handbrake 9 can be used to prevent the walker from sliding and other problems.

A pair of damping wheels 2 and a pair of steering wheels 4 are respectively provided on the left and right sides of the frame 1. A motor module is integrated inside the damping wheel 2. A drive box 3 is installed on the left side of the frame 1 near the damping wheel 2. A battery module is integrated inside the drive box 3. There are two battery modules, and the symmetrical design can ensure the balance property of the walker. An intelligent control console 6 is installed on the armrest of the frame 1. A display is integrated on the intelligent control console 6. The display can display the state of the walker itself and the damping state of the damping wheel 2.

A blood oxygen detection device 10 is installed on the inner armrest of the skeleton 1. The blood oxygen detection device 10 monitors the blood oxygen saturation and pulse through a blood oxygen saturation probe. The target heart rate can be set according to the patient's basic heart rate. When the target heart rate is reached or the blood oxygen saturation is lower than the set value, the data will be transmitted to the nurse station, and the nurse will intervene and stop the activity.

In this embodiment, a seat cushion 5 is provided at the waist of the skeleton 1 , and a backrest belt 12 is provided above the skeleton 1 . The backrest belt 12 can assist the patient to sit on the seat cushion 5 and provide a supporting force for leaning back.

Two lifting rods 7 are installed at the left and right ends of the frame 1, and the tops of the lifting rods 7 are provided with infusion hooks 8 (as shown in FIG. 1 ). The infusion hooks 8 can facilitate the patient to ensure that the infusion treatment is not interrupted while performing assisted walking.

A detachable medical device 11 is installed on the waist surface of the lifting rod 7, and the medical device 11 includes a micro pump or a feeding pump, etc. The medical device 11 assists the patient in feeding, injecting medicine, etc.

A system for an intelligent walker, wherein a GPS module, a blood oxygen monitoring module, a posture monitoring module and a WIFI transmission module are integrated on the intelligent control console. The GPS module is used to locate the position of the walker, that is, it can help the nurse station to quickly find the patient on the walker. The GPS module can also be used to prevent theft.

At the same time, the smart console also includes a Bluetooth module and a mobile data transmission module. Through the cooperation between the Bluetooth module and the mobile data transmission module, precise positioning can also be carried out through Bluetooth beacons and base stations deployed in the area, and the location of the device can be accurately determined to the department room in the hospital.

In this embodiment, the functions of the intelligent console include parking mode and walking mode. In the walking mode, the walker can calculate the walking distance and number of steps and display them on the intelligent console.

After the parking mode is activated, the damping wheel produces maximum damping to ensure that the walker is in a parking state; after the walking mode is activated, the walking mode includes a non-damping state and a damping state. The damping state in the walking mode includes three damping levels. The damping effect of the damping wheel increases step by step under the three damping levels. By designing different damping effects, patients can receive walking training of different levels.

In this embodiment, the working steps of the posture monitoring module include:

Step 1, determine whether the tilt angle of the walker itself is. The tilt angle of the walker itself exceeds 46°. Connect the nurse terminal through the WIFI transmission module, and transmit the information of the patient's fall. At the same time, the words "Patient falls, please treat in time" are displayed on the smart console, and the damping wheel produces the maximum damping; the angle of the walker itself. When the tilt is at 15°-25°, the words "The device is tilted, please pay attention to adjustment" are displayed on the smart console; when the tilt is at 26°-45°, the words "The tilt angle is too large, please pay attention to safety" are displayed on the smart console, and the damping wheel produces the maximum damping. The damping generated by the damping wheel can ensure that the walker will not cause secondary injuries due to sliding.

Step 2: After the equipment is straightened, the tilt angle is less than 15°. When the tilt angle is less than 15°, the damping wheel returns to the default damping state; when the tilt angle is not less than 15°, the damping wheel continues to produce maximum damping.

In this embodiment, the working process of the blood oxygen monitoring module includes:

Step 1: Determine whether the sensor end of the blood oxygen monitoring module is in contact with the patient's skin by checking whether the blood oxygen and pulse rate fluctuate. When the patient's blood oxygen is not detected, the function is in standby mode. This design can reduce energy consumption.

Step 2: Check whether the blood oxygen and pulse rate fluctuate under the condition of monitoring time. If there is fluctuation, the blood oxygen and pulse rate will show waveforms, which are refreshed once per second. Through continuous monitoring, it can be further determined whether there are patients to be monitored.

Step 3: The monitoring information of the blood oxygen monitoring module is transmitted to the server through the WIFI transmission module, and then transmitted to the nurse terminal of the corresponding department through the server.

In this embodiment, after receiving the monitoring information transmitted by the blood oxygen monitoring module or the posture monitoring module, the nurse terminal determines whether it is suitable to continue exercising. The blood oxygen and pulse rate of the patient are monitored by the blood oxygen monitoring module, and the monitoring results are uploaded to the nurse station of the corresponding department, so that the nurses and doctors of the corresponding department can make accurate judgments to determine whether the patient needs to continue exercising and resting.
