Detailed Description
The invention provides a medical walking aid walking safety protection system, when the medical walking aid walks in a slope, the medical walking aid can judge whether walking is safe according to the detection of the medical walking aid walking safety, so that whether walking is continued or stopped is judged, the medical walking aid walking and a user are safely protected, and medical accidents are avoided.
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in FIG. 2, the medical walker 10 includes:
(1) two foot plates, which for the sake of illustration are defined as a left foot plate 8 and a right foot plate 12, respectively. During walking using the medical walker 10, either the left foot plate 8 or the right foot plate 12 is in contact with the road surface.
(2) Two lower legs, which are positioned as a left lower leg 9 and a right lower leg 11, respectively, for ease of illustration.
As shown in figure 2, the walking safety protection system of the medical walking aid mainly comprises:
(1) the pressure sensors are respectively arranged on the foot plates, and at least one pressure sensor is arranged on each foot plate. For convenience of explanation, the left foot plate 8 is provided with the left foot plate pressure sensor 1, and the right foot plate 12 is provided with the right foot plate pressure sensor 7.
(2) The angle sensors are respectively arranged on the lower legs, and each lower leg is provided with at least one angle sensor. For convenience of explanation, the left leg 9 is provided with the left foot angle sensor 3, and the right leg 11 is provided with the right foot angle sensor 4. The left foot angle sensor 3 and the left foot plate pressure sensor are positioned on the same side, namely the left side, and are connected through the trigger signal transmission line 2; the right foot angle sensor 4 and the right foot plate pressure sensor 7 are positioned on the same side, namely the right side, and are also connected through the trigger signal transmission line 2.
(3) The central control processor 5 is arranged on the control center of the medical walking aid, and the central control processor 5 is respectively connected with the left foot angle sensor 3 and the right foot angle sensor 4 through angle signal transmission lines 6.
