Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a foldable auxiliary support stretcher that facilitates the transfer of orthopedic patients. Background Technology

[0002] The foldable auxiliary support stretcher for orthopedic patient transport is a medical transport device specifically designed for patients with bone injuries, spinal injuries, and mobility impairments. Through lightweight materials, ergonomic design, and orthopedic-specific functions, this type of stretcher significantly improves transport safety and efficiency, becoming a key piece of equipment in the medical emergency system.

[0003] However, existing foldable auxiliary support stretchers that are convenient for transporting orthopedic patients are inconvenient when transporting patients in narrow spaces; therefore, they do not meet the current needs. In response, we propose a foldable auxiliary support stretcher that is convenient for transporting orthopedic patients. Utility Model Content

[0004] The purpose of this invention is to provide a foldable auxiliary support stretcher that facilitates the transfer of orthopedic patients, in order to solve the problems mentioned in the background art, such as the inconvenience of transporting patients in narrow spaces.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a foldable auxiliary support stretcher for easy transport of orthopedic patients, comprising a first support frame and a second support frame. The bottom end of the first support frame and the top end of the second support frame are each provided with a U-shaped connector. The first and second support frames are movably connected to a rotating shaft via fastening bolts on the corresponding U-shaped connectors. Both top ends of the first support frame are provided with handle mounting holes. Rotary handles are mounted in each of the two handle mounting holes via fastening bolts. The surface of the rotary handle is provided with a first anti-slip texture. Below the rotary handle, and on the upper end face of the first support frame, are five limiting holes penetrating the first support frame. Below the limiting holes are roller mounting holes. The first support frame is a hollow structure, and a first support leg is slidably provided inside. The bottom end of the second support frame has a support leg mounting groove, and a second support leg is mounted inside the support leg mounting groove via fastening bolts. The handle surface at the bottom end of the second support frame is provided with a second anti-slip texture.

[0006] Preferably, the first support leg further includes a first bracket, the upper end face of which is provided with a limiting and fixing hole, and the bottom end of the first bracket is provided with a first universal wheel.

[0007] Preferably, the second support leg further includes a second bracket, the second bracket having a pivot hole near its top, a fixing hole below the pivot hole and near the bottom of the second bracket, and a second universal wheel on the bottom end face of the second bracket.

[0008] Preferably, a support plate is provided between the two arms of the first support frame and between the two arms of the second support frame.

[0009] Preferably, the first support leg is adjustablely fixed inside the first support frame by means of fastening bolts and limiting holes and limiting fixing holes.

[0010] Compared with the prior art, the beneficial effects of this utility model are: In use, first place the stretcher with the bottom facing upwards, remove the fastening bolts in the fixing holes of the second support leg, then loosen the fastening bolts at the pivot hole to rotate the second support leg to a vertical position, and retighten the fastening bolts at the pivot hole to complete the fixing and opening of the second support leg. Next, turn the stretcher back to face upwards, loosen the fastening bolts of the U-shaped connectors on both sides, rotate the first support frame around the pivot to make it perpendicular to the horizontal plane where the second support frame is located, and lock the fastening bolts of the U-shaped connectors to fix the angle. Then, remove the fastening screws fixing the first support leg, allowing the first support leg to slide out from inside the first support frame. After adjusting to a suitable position, align the first support leg with the limit. Insert and tighten the fixing bolts into either the fixing hole or the limiting hole of the first support frame to fix the height of the first support leg. Loosen the fixing bolts of the rotating handle so that the rotating handle is perpendicular to the horizontal plane. Finally, tighten the fixing bolts of the rotating handle to complete the deformation of the stretcher. This utility model effectively solves the problem of transportation in narrow spaces by transforming the stretcher into a simple wheelchair. The sliding design of the first support leg allows doctors to adjust the tilt angle of the stretcher according to the patient's injury, avoiding secondary injury during transport. In addition, by cooperating with the fixed height of the second support leg, a support surface that is higher in the front and lower in the back or lower in the front and higher in the back can be formed to adapt to different terrains and reduce the risk of fracture displacement.
