Problems solved by technology

[0004] However, in reality, users who use crutches cannot intuitively understand their own training status and possible dangers; at the same time, rehabilitation physicians cannot always be with patients, so it is impossible to understand the use of crutches and the level of rehabilitation of patients in real time. At the same time, it is impossible to provide advice to patients in a timely manner, which affects the quality and progress of rehabilitation.

example 1

[0020] In this example, a gyroscope known in the prior art is installed in the handle of the crutch to provide a gravity direction reference G1; and four pressure sensors are installed in the four legs to detect the Pressure F1, F2, F3, F4 on the four feet. As shown in Figure 3, according to the balance algorithm, under the condition of normal use of crutches, the pressure detected on the four feet is basically evenly distributed, that is, F1, F2, F3, and F4 are basically equal, so the central controller 203 can establish a sensor data schema diagram according to the sensor data, such as Figure 3A As shown, the center of mass Q of the graph is basically located at the center and coincides with the gravity direction G1, or may be within a predetermined deviation range, and the sensor data model graph is used as a reference graph.

[0021] When the user shows signs of falling, abnormal use of crutches is bound to occur. Therefore, the pressures F1, F2, F3, and F4 detected on ...

example 2

[0024] In this example, the first sensor or the second sensor may also include a pressure sensor and an acceleration sensor or a single acceleration sensor. The development of existing technologies has made it possible to use acceleration sensors to achieve accurate motion detection, detect force changes due to drops, tilts, motions, positions, shocks, and vibrations, and to achieve step counting functions. The user's steps in a unit or a period of time are very beneficial to judge the user's health status. Moreover, the use of an acceleration sensor to calculate the number of steps is less costly than the GPS commonly used in electronic devices, and is not affected by the accuracy of the GPS. Of course, the present invention is not limited to the acceleration sensor, and GPS can still be used to realize functions such as positioning and distance calculation. For example, positioning devices such as GPS receivers and Beidou positioning system receivers can be separately provi...

Abstract

A crutch walker (100) having an embedded monitoring system, comprising a handle (101), a cane body (103) and a plurality of feet (102-1, 102-2, 102-3, 102-4) providing support at the ground, the walker (100) further comprising: a first sensor (201) disposed in the handle (101) or cane body (103), being for detecting a state of the crutch (100) so as to provide a first movement parameter; at least one second sensor (202) disposed in at least one foot of the plurality of feet (102-1, 102-2, 102-3, 102-4), for detecting a state of the crutch (100) so as to provide a second movement parameter; a central controller (203), configured to determine a movement state on the basis of at least one of the first movement parameter and the second movement parameter so as to enable more timely, more accurate acquisition of user rehabilitation level data, thereby providing more targeted and timely training plans.

Description

technical field [0001] The invention relates to a crutch, in particular to a crutch walker with a walking aid monitoring function. Background technique [0002] Crutches can enable the elderly, patients and other users who have inflexible legs and feet or even lose the ability to walk to take care of themselves and maintain a certain degree of mobility, and can also assist the elderly or patients to enhance their mobility to achieve the purpose of rehabilitation. [0003] At present, for patients or the elderly who need rehabilitation training, the pathology and physiology of the patient are usually checked by the rehabilitation physician or rehabilitation engineer, and the type of walking stick that should be selected is determined under the guidance of the rehabilitation physician or rehabilitation engineer. Determine supplementary training programs. The patients, with the help of a rehabilitation therapist, performed some pre-use training on walking sticks. At the same ...
