Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a foldable walker with an infusion stand. Background Art

[0002] Walkers, also known as lower limb orthoses, are walking aids widely used in homes, hospitals, and rehabilitation facilities. They assist individuals with mobility issues, the elderly, or lower limb disabilities in walking or rehabilitation training. Walkers can be categorized as fixed, interactive, or front-wheeled. Fixed walkers are often used to reduce the load on one lower limb. For example, when a lower limb injury or fracture precludes weightbearing, the user lifts both armrests with both hands and places them forward on the ground, replacing one foot. The healthy leg then steps forward. Interactive walkers are smaller, lack wheels, and are height-adjustable. To use, the user first moves one side forward, then the remaining side, alternating back and forth. They are suitable for patients with poor standing balance, lower limb muscle strength, or the elderly, and offer convenient access to the toilet. Front-wheeled walkers are used for individuals with upper limb weakness who have difficulty lifting the walker on one side or the entire body. In this case, the front wheels touch the ground, and the walker is lifted and pushed forward with the back foot to walk.

[0003] At present, in clinical practice, with the continuous advancement of surgical diagnosis and treatment techniques and equipment, the number of difficult and complicated surgeries in various surgical specialties is also increasing. Difficult and complicated surgeries take a long time and cause great trauma. After surgery, patients are unable to get out of bed and move around early because they have many drainage tubes and need a large amount of infusion. In order to increase the patient's activity level after surgery and facilitate their recovery, there is an urgent need for a walker that can meet the patient's needs for infusion, drainage, and getting out of bed. Therefore, in the prior art, there is an infusion walker disclosed in the patent document with application number CN202121371219.4. The key points of its technical solution are that the infusion walker includes a walking frame and an infusion frame, the infusion frame is located above the walking frame and connected to the top of the walking frame, the walking frame is provided with at least one hook for hanging a drainage bag, and the bottom of the walking frame is provided with a pulley. By arranging an infusion stand and a hook on the walker, and arranging a pulley at the bottom of the walker, an IV bottle can be hung on the infusion stand and a drainage bag can be hung on the hook. The patient can use the infusion walker to get out of bed and move around. The pulley brings convenience to the patient in pushing the walker, and also keeps the IV bottle on the infusion stand and the drainage bag on the hook stable during the movement, avoiding violent shaking or even falling and causing injury to the patient.

[0004] However, the above technical solution still has shortcomings that need to be improved. For example, the folding and storage method of the walker is not good, resulting in the walker still occupying a large space after folding. At the same time, the infusion stand on the walker cannot be removed from the walker, and the high center of gravity easily makes the walker unstable. Utility Model Content
