Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a nursing wheelchair with leg supports. Background Technology

[0002] A wheelchair is a chair equipped with wheels that can help replace walking. It is an important mobility tool for the injured, sick, and disabled to use at home for rehabilitation, transportation, medical treatment, and outdoor activities. Wheelchairs not only meet the mobility needs of people with limb disabilities and limited mobility, but more importantly, they facilitate the movement and care of family members, and enable patients to exercise and participate in social activities with the help of wheelchairs.

[0003] Wheelchairs with leg rests have already appeared on the market, such as the Chinese utility model patent with publication number CN221712556U entitled "A Wheelchair with Movable Leg Rests". The footrest structure of this wheelchair with movable leg rests can be adjusted up and down by cooperating with the gear support rod, which has a better user experience. However, some patients wear leg braces, such as those with Steinmann pins and needing to wear braces for Steinmann pin traction and fixation. When the patient needs to sit in the wheelchair, the brace needs to be placed on the leg rest at the same time. During the process of moving the wheelchair with movable leg rests, the brace is prone to tipping over or shifting. During the tipping or shifting of the brace, there is a risk of secondary injury to the patient's legs.

[0004] In view of this, the applicant has conducted in-depth research on the above-mentioned issues, which led to this case. Utility Model Content

[0034] The terms "first", "second", "third", "fourth", "fifth", etc., in the specification, claims and drawings of this utility model are used to distinguish different objects, rather than to describe a specific order.

[0035] like Figures 1-4As shown, for ease of description, the end of the wheelchair facing forward while the patient sits is considered the front end, and the corresponding other end is considered the rear end. This embodiment provides a nursing wheelchair with leg supports, including a wheelchair body 10. It should be noted that the wheelchair body 10 is a conventional wheelchair, which can be purchased directly from the market and will not be described in detail here. A fixing plate 20 is fixedly installed on one side of the wheelchair body 10 near its front end. In this embodiment, the fixing plate 20 is located on the right side of the wheelchair body 10. The fixing plate 20 is installed to the wheelchair body 10 in a conventional way, such as by bolt connection. The fixing plate 20 is arranged vertically and extends along the front-rear direction of the wheelchair body 10. A leg support 21 is hinged to the outer side of the fixing plate 20 through a hinge shaft. The hinge shaft is connected to the fixing plate. The fixed plate 20 is vertically arranged, and an angle adjustment component is provided on the outer side of the fixed plate 20 for adjusting the angle between the leg rest 21 and the wheelchair body 10. The leg rest 21 includes a leg rest pad 31, and a protective device (not shown in the figure) is detachably connected to the leg rest pad 31. It should be noted that the protective device is a conventional protective device, such as a protective device for traction fixation of the patient's leg when a Steinmann pin is inserted. It will not be described in detail here. The leg rest pad 31 has a second threaded hole 32, and the lower side of the protective device has a first positioning through hole (not shown in the figure). A second bolt 33 is inserted into the second threaded hole 32. The second bolt 33 is screwed into the second threaded hole 32 and inserted into the first positioning through hole. A rectangular part is arranged along the length of the leg rest pad 31. Hole 34, the second threaded hole 32, and the rectangular hole 34 are located on the same straight line. A hexagonal nut 35 is slidably connected in the rectangular hole 34. The sliding direction of the hexagonal nut 35 is the same as the length direction of the leg support pad 31. Specifically, the rectangular hole 34 has grooves on the sidewalls corresponding to the long side of its rectangular cross-section. The opposite sidewalls of the hexagonal nut 35 are slidably connected to the grooves one-to-one. The maximum inner diameter of the hexagonal nut 35 is smaller than the length of the sidewall corresponding to the short side of the rectangular hole 34. The rectangular hole 34 has notches on the sidewalls corresponding to the long side of its rectangular cross-section that communicate with the grooves. The hexagonal nut 35 is inserted into the grooves through the notches. A second positioning through hole (not shown in the figure) is provided on the lower side of the guard. As shown), a third bolt 36 is inserted into the hexagonal nut 35. The third bolt 36 is screwed into the hexagonal nut 35 and inserted into the second positioning through hole. The third bolt 36 is also screwed to a third nut 37 that abuts against the lower side of the leg support pad 31. In use, the second bolt 33 is screwed out of the second threaded hole 32 and inserted into the first positioning through hole, and the third bolt 37 is screwed out of the rectangular hole 34 and inserted into the second positioning through hole. Through the use of the sliding groove, the hexagonal nut 35, the second positioning through hole, the third nut 37 and the third bolt 36, the protective gear will not easily flip or move, effectively avoiding secondary injury to the patient's leg. At the same time, through the use of the rectangular hole 34 and the hexagonal nut 35, it can be used for protective gear of different lengths, and its application range is relatively wide.

[0036] The angle adjustment assembly includes a shift support plate 22 located below the leg rest 21. The shift support plate 22 is arranged parallel to the fixed plate 20. One end of the shift support plate 22 is rotatably connected to the leg rest 21. The shift support plate 22 has a first strip-shaped hole 23 arranged along its length. The shift support plate 22 also has multiple parallel second strip-shaped holes 24 arranged along its length. The included angle between the first strip-shaped hole 23 and the second strip-shaped hole 24 is an acute angle, and the included angle between the first strip-shaped hole 23 and the second strip-shaped hole 24 faces the position where the shift support plate 22 and the leg rest 21 are rotatably connected. Each second strip-shaped hole 24 is located above the first strip-shaped hole 23. One end of each second strip-shaped hole 24 is connected to the first strip-shaped hole 23, and the other end of each second strip-shaped hole 24 is connected to an arc-shaped hole 25. The arc center of each arc-shaped hole 25 faces one side of the first strip-shaped hole 23. The arc-shaped hole 25, the first strip-shaped hole 23, and each second strip-shaped hole 24 are connected together. The two holes 24 together form a gear shift hole. A limiting bolt 26 is fixedly installed on the fixing plate 20, which is movably inserted into the gear shift hole and arranged perpendicularly to the fixing plate 20. It should be noted that the diameter of the screw of the limiting bolt 26 is smaller than the width of the second strip hole 24 and the diameter of the screw of the limiting bolt 26 is smaller than the width of the first strip hole 23. In use, the limiting bolt 24 slides out from the arc hole 25 and enters the corresponding second strip hole 24, then slides out from the second strip hole 24 and enters the first strip hole 23. Depending on the actual situation, the limiting bolt 24 can be moved from the first strip hole 23 into another second strip hole 24, and then from the second strip hole 24 into the corresponding arc hole 25. The angle between the leg rest 21 and the wheelchair body 20 can be adjusted by the engagement of the limiting bolt 26 and each arc hole 25 to meet different usage needs. Even if the limiting bolt 26 is hit by an external object, it will not easily slide out of the arc hole 25, effectively avoiding secondary injury to the patient's legs.
