Description

Technical Field

[0001] This utility model relates to the field of nursing crutches, specifically a portable orthopedic nursing crutches. Background Technology

[0002] In orthopedic nursing, crutches are assistive walking devices primarily used to help patients reduce the burden on their lower limbs, improve walking stability and safety. They are commonly used for orthopedic patients, such as those recovering from fractures, undergoing joint replacements, experiencing muscle weakness, or suffering nerve damage, to help them regain walking function and promote rehabilitation.

[0003] To achieve the above functions, a prior art Chinese patent (publication number: CN215132767U) discloses a portable orthopedic nursing crutch, including an orthopedic nursing external crutch assembly. An orthopedic nursing internal crutch assembly is slidably disposed inside the external crutch assembly, and a handgrip assembly is sleeved on the outside of the external crutch assembly. The handgrip assembly's up-and-down sliding on the outside of the external crutch assembly changes the grip distance between the handgrip assembly and the arc-shaped armpit support plate. The internal crutch assembly's up-and-down sliding on the inside of the external crutch assembly changes the actual support length of the crutch during use. Changing the grip distance between the handgrip assembly and the arc-shaped armpit support plate meets the handgrip needs of patients with different arm lengths, and changing the actual support length of the crutch during use meets the needs of patients with different heights.

[0004] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation: Orthopedic nursing crutches are designed to be portable through retraction or folding, but in actual use, crutches are generally divided into two types: underarm crutches and forearm crutches, and the choice is made according to the patient's actual situation. However, the existing orthopedic nursing crutches have relatively limited functions. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please refer to Figure 1 - Figure 4 This utility model provides the following technical solution: a portable orthopedic nursing crutch, including an adjusting rod 1, a rotating rod 2 rotatably connected to the upper end of the adjusting rod 1, and vertically distributed rotating structures at the connection points of the adjusting rod 1 and the rotating rod 2, and the adjusting rod 1 and the rotating rod 2 are parallel to each other; a replacement part is installed at the end of the rotating rod 2 away from the adjusting rod 1, the first replacement part includes a first replacement rod 3 detachably installed at the end of the rotating rod 2, the second replacement part includes a second replacement rod 4 detachably installed at the end of the rotating rod 2, a main mounting sleeve 7 is fixedly connected to the upper end of the first replacement rod 3, and a secondary mounting sleeve 7 is fixedly connected to one side of the upper end of the first replacement rod 3, which is perpendicular to the first replacement rod 3. Mounting sleeve 8; a fixed handle 6 is fixedly connected to one side of the lower end of the second replacement rod 4, which is perpendicular to it; a positioning ring 5 is fixedly connected to one side of the upper end of the second replacement rod 4, and the positioning ring 5 and the fixed handle 6 are located on the same side; a sliding sleeve 9 is slidably connected to the outside of the first replacement rod 3; a hand-tightening screw 10 is threadedly connected to one side of the sliding sleeve 9, which is perpendicular to the first replacement rod 3, and the end of the hand-tightening screw 10 passes through the sliding sleeve 9 and fits against the outside of the first replacement rod 3; a rotating handle 11 is rotatably connected to the side of the sliding sleeve 9 away from the hand-tightening screw 10, and the rotation angle of the sliding sleeve 9 is 0° to 90°; an armpit support 12 is detachably connected to the top of the first replacement rod 3 through the main mounting sleeve 7 and the auxiliary mounting sleeve 8.

[0027] The core function of this portable orthopedic nursing cane is achieved through the vertical rotation connection between the adjusting rod 1 and the rotating rod 2. The adjusting rod 1 serves as the main support structure, and its top is hinged to the rotating rod 2 through a rotating structure, allowing both to fold from 0° to 180° in the vertical plane. When folded, the armpit support 12 is installed on the secondary mounting sleeve 8, so that the armpit support 12 and the first replacement rod 3 are distributed in parallel. When the rotating rod 2 is unfolded, the cane is put into use. When folded, the two overlap, significantly reducing the storage volume. The end of the rotating rod 2 is designed with a replaceable module, which allows for quick switching between armpit support and forearm support modes by installing the first replacement rod 3 or the second replacement rod 4.

[0028] When the first replacement rod 3 is selected, the main mounting sleeve 7 at its top is used to install the axillary support 12 via a plug-in connection. The main sliding sleeve 9 is fitted onto the outside of the first replacement rod 3. The vertical height adjustment function is achieved by manually tightening the hand screw 10. When the hand screw 10 is loosened by rotation, the sliding sleeve 9 can slide up and down along the surface of the first replacement rod 3. After adjusting to a comfortable height for the patient, the hand screw 10 is tightened clockwise to fix the position. The rotating handle 11 on the side of the sliding sleeve 9 can be folded to be parallel to the sliding sleeve 9 when not in use. When in use, it can be rotated outward to unfold to a vertical angle to form an ergonomic hand grip.

[0029] If switched to the second replacement rod 4, the fixed handle 6 at its lower end can be used directly as a hand grip, while the positioning ring 5 at the top is used to fix the patient's forearm. The second replacement rod 4 makes the positioning ring 5 and the fixed handle 6 form a distance that conforms to the natural bending angle of the forearm. When the patient inserts the forearm into the positioning ring 5, the support stability is ensured by appropriate restraint.

[0030] Example 2: Based on Example 1, please refer to... Figure 5 - Figure 7 The following structure is also disclosed: a quick-release structure is provided at the connection between the rotating rod 2 and the first replacement rod 3, and the rotating rod 2 and the second replacement rod 4. The quick-release structure includes a first positioning slider 13 slidably connected to the lower end of the first replacement rod 3 and the second replacement rod 4, and the two first positioning sliders 13 are connected by a spring. The ends of the rotating rod 2 are provided with first positioning holes 14 aligned with the first positioning sliders 13, and the first positioning sliders 13 are engaged with the inside of the first positioning holes 14. The rotating structure includes a rotating joint 15 fixedly connected to the end of the rotating rod 2. A second positioning slider 16 is slidably connected inside the rotating joint 15. A spring is fixedly connected between one end of the second positioning slider 16 inside the rotating joint 15 and the inner wall of the rotating joint 15. The end of the adjusting rod 1 is provided with two second positioning holes 17 aligned with the second positioning slider 16, and the rotating joint 15 is rotatably connected to the inner side of the end of the adjusting rod 1. A third positioning hole 18 is provided on one side of the adjusting rod 1. A telescopic rod 19 is slidably connected inside the adjusting rod 1. A third positioning slider 20 is rotatably connected to the upper end of the telescopic rod 19. A spring is fixedly connected between one end of the third positioning slider 20 inside the telescopic rod 19 and the inner wall of the telescopic rod 19, and the third positioning slider 20 is engaged inside the third positioning hole 18.

[0031] The bottom ends of the first replacement rod 3 and the second replacement rod 4 are each provided with symmetrically arranged first positioning sliders 13. The two sliders are kept in an outward expansion trend by a compression spring. When a replacement part needs to be installed, the interface at the bottom of the replacement rod is aligned with the end of the rotating rod 2. At this time, the first positioning slider 13 is squeezed inward by the end face of the rotating rod 2. After it is fully inserted, the spring pushes the first positioning slider 13 outward and accurately locks into the first positioning holes 14 on both sides of the rotating rod 2 to form a rigid connection. When disassembling, simply press the unlocking buttons on both sides of the replacement rod at the same time to make the first positioning slider 13 disengage from the first positioning hole 14, and the replacement part can be quickly separated.

[0032] The swivel joint 15, as an extension of the rotating rod 2, has a second positioning slider 16 that can slide laterally inside. This slider always has an outward tendency under the action of a spring. When the rotating rod 2 rotates relative to the adjusting rod 1, the second positioning slider 16 rotates at the end of the adjusting rod 1. Whenever the rotation angle is 180°, the second positioning slider 16 automatically engages with the corresponding second positioning hole 17 under the push of the spring, emitting a clear positioning sound. At this time, the rotating rod 2 is locked at the current angle, providing clear angle positioning feedback.

[0033] Press the third positioning slider 20 on the top of the telescopic rod 19 to retract it into the rod body. At this time, the telescopic rod 19 can slide freely along the axis of the adjusting rod 1. When the telescopic rod 19 is aligned with the required third positioning hole 18, release the third positioning slider 20. The spring will immediately push it out and lock it into the third positioning hole 18 to complete the height locking.
