Description

Technical Field

[0001] The utility model relates to the technical field of orthopedic nursing crutch, in particular to a portable orthopedic nursing crutch. Background Art

[0002] Orthopedics, also widely known as orthopedic surgery, is a professional discipline in the field of medicine that focuses on the anatomical structure, physiological characteristics and pathological changes of the musculoskeletal system. Through the implementation of drug treatment, surgical treatment and physical therapy, its goal is to maintain and promote the normal form and function of the musculoskeletal system, and it is also committed to treating various diseases that occur in this system. As a commonly used medical device in orthopedic care, nursing crutches have a wide range of usage scenarios. However, existing nursing crutches occupy a large area and cannot be folded for transportation and carrying, which is inconvenient. For example, the prior art represented by the comparative document, a portable orthopedic nursing crutch (publication number CN215132767U), this patented technology uses a hand-held arm assembly in orthopedic care. The outer part of the external crutch assembly slides up and down to change the grip distance between the hand-grip arm assembly and the arc-shaped armpit support plate. The orthopedic nursing inner crutch assembly slides up and down inside the orthopedic nursing outer crutch assembly to change the actual support length of the crutch when in use. By changing the grip distance between the hand-grip arm assembly and the arc-shaped armpit support plate, the hand grip requirements of patients with different arm lengths are met when using the crutch. By changing the actual support length of the crutch when in use, the requirements of patients with different heights are met when using the crutch, thereby effectively solving the existing technical problems. However, its structure still needs to be improved, as follows:

[0003] In this solution, when orthopedic patients use the armpit support to hold their arms for support, they need to pull the pull ball head in the handgrip assembly outward with their hands. The pull ball head is small, and single-handed operation requires them to feel for the pull ball head first before pulling it outward, and then lift the device to adjust the height. Due to the pulling force applied outward, the crutch must be clamped, otherwise the lower side of the crutch may slide outward due to the outward pulling force, posing a risk of falling. It is laborious and not practical. Therefore, a portable orthopedic nursing crutch is needed to improve the above problems. Utility Model Content

At the same time, the limit shell 602 is installed on the inner wall opposite to the upper bracket 1, and the port of the limit shell 602 is slidably connected with a ejector pin 605, and one end of the ejector pin 605 is plugged and connected to the inner wall of the positioning hole 5 for fixation, and the other end of the ejector pin 605 is installed with a positioning spring 606, one end of the positioning spring 606 is connected to the inner wall of the limit shell 602, and a positioning shell 607 is embedded in the outer wall of the limit shell 602, and the inner wall of the positioning shell 607 The upper slide is connected with a pull wire 608, one end of the pull wire 608 is connected to the outer wall of the ejector pin 605, and the other end of the pull wire 608 is connected to the outer wall of the slide bar 601. When the slide bar 601 moves up, the slide bar 601 drives the pull wire 608 to move up, and the pull wire 608 slides on the inner wall of the positioning shell 607. One end of the pull wire 608 pulls the ejector pin 605 to apply tension, thereby causing the ejector pin 605 to slide inward on the inner wall of the limit shell 602. One end of the ejector pin 605 is disconnected from the positioning hole 5, and the upper bracket 1 can slide upward on the outer wall of the connecting rod 8 to adjust the height of the nursing crutch to suit people of different heights. When the ejector pin 605 moves inward, its positioning spring 606 is compressed. When it is adjusted to a suitable height, the slide bar 601 is released, and its ejector pin 605 loses its pulling force. The compressed positioning spring 606 stretches to push the ejector pin 605 outward, thereby inserting the ejector pin 605 into the positioning hole 5 for fixation. The use of the device is more convenient and safe, thereby solving the problem of one-handed operation requiring first groping for the pull ball head before pulling it outward and then lifting the device to adjust the height. Due to the pulling force applied outward, the crutch must be clamped, otherwise the lower side of the crutch may slide outward due to the outward pulling force, posing a risk of falling, which is laborious and impractical.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
