Description

Technical Field

[0001] The utility model relates to the technical field of fracture rehabilitation, in particular to an orthopedic nursing walker. Background Art

[0002] Orthopedics is one of the most common departments in major hospitals. It mainly studies the anatomy, physiology and pathology of the musculoskeletal system, and uses drugs, surgery and physical methods to maintain and develop the normal form and function of this system. Orthopedics often accepts patients with fractures for treatment. After a period of time after the treatment of patients with lower limb fractures, when fracture patients need to walk, they need walkers to help them walk;

[0003] A walker is a device that supports body weight, protects balance and assists walking. Existing walkers are usually divided into alternating walkers, lifting walkers, front-wheel walkers and four-wheel walkers. Existing walkers have simple structures and good stability and are often used to reduce the load on the lower limbs. Patients with fractures who are not allowed to bear weight or have weak lower limb muscles and poor coordination can choose different walkers according to their needs to maintain body balance and help rehabilitation.

[0004] The utility model with announcement number CN215308013U discloses a multifunctional orthopedic care walking aid device, which relates to the technical field of medical care equipment. It can be suitable for users of different heights, and the first flap and the second flap can be rotated to a horizontal state, which can facilitate users to sit down and rest when they are tired, thereby improving practicality.

[0005] However, in the above-mentioned prior art, when the patient is tired of walking and needs to rest, he needs to control the second flap with one hand and hold the handle with the other hand to unfold the first flap and the second flap and sit on them. If the patient is not careful during this process, it is easy to cause the patient to fall, which will aggravate the patient's condition and has low safety. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3The utility model discloses an orthopedic care walker, comprising a mobile base 1, a positioning structure 2 is provided at the bottom of the mobile base 1, a mounting structure 3 is fixedly installed at the top of the mobile base 1, and a retractable seat structure 4 is arranged inside the mounting structure 3; the positioning structure 2 comprises a driving box 6, a hydraulic cylinder 7 is fixedly installed on the inner wall of the driving box 6, and the movable end of the hydraulic cylinder 7 is fixedly connected with a contact plate 8, and the contact plate 8 is located below the driving box 6; the mounting structure 3 comprises a mounting bracket 9, a holding armrest 10 is fixedly connected to the top of the mounting bracket 9, and the brake box 11 is located on the inner side of the mounting bracket 9; the retractable seat structure 4 comprises a brake box 11, the inner wall of the brake box 11 is rotatably connected with a rotating shaft 12, and a seat cushion plate 13 is fixedly sleeved on the surface of the rotating shaft 12, and the seat cushion plate 13 is located at the opening of the brake box 11, and the inner wall of the brake box 11 is rotatably connected with a screw 15 through a built-in motor, and the screw 15 The surface of the seat is threadedly connected with a threaded sleeve 16, and the front end of the threaded sleeve 16 is hinged with a hinge rod 17, and the front end of the hinge rod 17 is hinged with a ball joint 18, and the other end of the ball joint 18 overlaps the seat cushion 13, and the bottom of the seat cushion 13 is provided with a hemispherical groove 14, and the other end of the ball joint 18 extends into the hemispherical groove 14 and is slidably connected with the inner wall of the hemispherical groove 14; by setting the positioning structure 2 and the retractable seat structure 4, the hydraulic cylinder 7 inside the drive box 6 included in the positioning structure 2 can drive the contact floor 8 to gradually contact the ground, and then cooperate with the screw 15 included in the retractable seat structure 4 to prompt the threaded sleeve 16 to drive the seat cushion 13 to gradually unfold through the hinge rod 17, so that the walker can provide a seat rest function after completing its own positioning, and the whole process is mechanically operated, avoiding the manual adjustment method used in the comparative scheme to achieve the seat function, so that the completeness of the use of the walker is significantly improved.

[0022] Specifically, a universal wheel is provided at the bottom of the mobile base 1, and a mounting recess 5 is opened in the mobile base 1. The outer wall of the drive box 6 is fixedly connected to the inner wall of the mounting recess 5. A battery 19 is provided inside the mobile base 1, and the battery 19 is electrically connected to the positioning structure 2 and the retractable seat structure 4 respectively.

[0023] In this embodiment, the battery 19 can be used to supply power to the positioning structure 2 and the retractable seat structure 4 in a timely manner, thereby ensuring that the positioning structure 2 and the retractable seat structure 4 can be used normally.

[0024] When the patient needs to unfold the cushion plate 13 to rest during use of the walker, the positioning structure 2 is activated in advance, so that the movable end of the hydraulic cylinder 7 drives the contact plate 8 to gradually contact the ground, so that the contact plate 8 can lift the mobile base 1 off the ground, so that the contact plate 8 drives the universal wheels of the mobile base 1 to support the mobile base 1;

[0025] Then, the retractable seat structure 4 is started, so that the output shaft of the built-in motor drives the screw rod 15 to rotate. Since the threaded sleeve 16 is provided with a threaded groove matched with the surface of the screw rod 15, the rotation of the screw rod 15 will drive the threaded sleeve 16 to move in the axial direction, so that the movement of the threaded sleeve 16 will drive the hinged rod 17 to deflect at an angle. Since the front end and the back end of the hinged rod 17 are not on the same vertical line in the initial state, the initial state of the hinged rod 17 is an inclined state, so the displacement of the threaded sleeve 16 will drive the front end and the back end of the hinged rod 17 to gradually be on the same vertical line, so that the hinged rod 17 is finally perpendicular to the screw rod 15. In this process, the front end of the hinged rod 17 will drive the ball joint 18 to slide along the inner wall of the hemispherical groove 14, so that the ball joint 18 drives the seat cushion 13 to gradually adjust from a state perpendicular to the ground to a state parallel to the ground, so that the seat cushion 13 is unfolded, so that the patient can sit on the seat cushion 13 to rest.

[0026] To summarize, the orthopedic care walker, by setting a positioning structure 2 and a retractable seat structure 4, utilizes the hydraulic cylinder 7 inside the drive box 6 included in the positioning structure 2 to drive the contact plate 8 to gradually contact the ground, and then cooperates with the screw 15 included in the retractable seat structure 4 to prompt the threaded sleeve 16 to drive the seat cushion 13 to gradually unfold through the articulated rod 17 so that the ball joint 18 drives the seat cushion 13 to gradually unfold, so that the walker can provide a seat rest function after completing its own positioning, and the entire process is mechanically operated, avoiding the manual adjustment method used in the comparative scheme to achieve the seat function, so that the completeness of the use of the walker is significantly improved.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
