Description

Technical Field

[0001] This utility model relates to the field of mountain rescue equipment, specifically a foldable support device for mountain rescue. Background Technology

[0002] Rescue stretchers are crucial equipment for the safe transfer of injured or immobile individuals at emergency rescue sites. They are typically made of lightweight yet sturdy materials and designed for stability and adaptability. They are usually equipped with harnesses, handles, and other auxiliary features to ensure the smooth transport of the injured even in complex terrain, making them indispensable tools for medical personnel, rescue teams, and outdoor emergency rescue operations. In the prior art, the authorized announcement number CN222150320U discloses a portable rescue stretcher, which relates to the field of medical equipment. It includes a stretcher pole, one end of which is equipped with a folding mechanism. The folding mechanism includes a rotating rod, a spring, and a latch. The rotating rod is welded to one end of the stretcher pole. A spring is installed on the inner wall of the stretcher pole, and one end of the spring abuts against the latch. A support rod is installed on one side of the folding mechanism.

[0003] Mountain rescue environments are typically extremely complex and treacherous, often requiring rescuers to carry patients over long distances. Due to the rugged terrain and difficult roads, coupled with the weight of the stretcher and the patient, rescuers experience significant physical exertion, frequently needing to stop for rest and recovery. In such emergencies, to ensure rescuers can regain their strength and continue, it's necessary to temporarily place the patient on the ground. However, many mountainous areas have very harsh ground conditions, being uneven and frequently damp and cold due to rain, fog, or streams. This damp environment can easily cause secondary injury to already wounded patients, potentially leading to wound infection, hypothermia, and other serious consequences, further hindering recovery and complicating subsequent treatment.

[0017] 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.

[0018] Example 1: As Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a foldable support device for mountain rescue, including a frame assembly 6, a stretcher beam 2 fixedly installed on the frame assembly 6, a carrying strap 3 fixedly installed on the stretcher beam 2, auxiliary handles 4 connected to the edges of both ends of the frame assembly 6, a stretcher pad 1 connected to the frame assembly 6, a strap 5 connected to the frame assembly 6, and handle assemblies 7 provided at both ends of the long frame 605.

[0019] When folded up, the entire device can be carried on the back using the shoulder straps 3, facilitating rescue missions in mountainous environments. When used in conjunction with the handle assembly 7, the frame assembly 6 provides a stable frame structure for the stretcher pad 1, facilitating patient transfer and supporting the stretcher to prevent the patient from contacting the wet ground.

[0020] Example 2: Figure 2 and Figure 3As shown, the frame assembly 6 includes a short frame 601, with a long frame 605 rotatably mounted at both ends of the short frame 601. Both the short frame 601 and the long frame 605 are provided with connecting threads 606, and a first threaded sleeve 604 is threadedly installed at the connecting threads 606. A first support leg 602 is fixedly mounted at both ends of the short frame 601, and a first rotating shaft 603 is fixedly mounted on the long frame 605. The first rotating shaft 603 is rotatably mounted on the first support leg 602, and a rotating groove is provided on the first support leg 602. The first rotating shaft 603 is rotatably mounted on the first support leg 602 through the rotating groove.

[0021] Specifically, the long frame 605 can rotate around the first pivot 603, thereby unfolding the long frame 605. After unfolding to a horizontal position, the long frame 605 is aligned with the short frame 601. After the long frame 605 and short frame 601 are aligned, the first threaded sleeve 604 can be rotated to thread the long frame 605 and short frame 601 together, thus fixing the long frame 605 and short frame 601. This provides a stable frame structure for the stretcher pad 1, facilitating the transfer of patients.

[0022] Example 3: Figure 4 and Figure 5 As shown, the handle assembly 7 includes a threaded post 701 fixedly installed on the long frame 605 and a handle frame 707 rotatably connected to the end of the long frame 605. Threaded posts 705 are fixedly installed at both ends of the handle frame 707. A second threaded sleeve 706 is threadedly connected to the threaded post 701 and the threaded post 705. A second support leg 702 is fixedly installed on the threaded post 701. A second rotating shaft 704 is fixedly installed on the threaded post 705 and rotatably installed on the second support leg 702. A locking pin 703 is connected to the threaded post 705. A rotating groove is provided on the second support leg 702. The second rotating shaft 704 is rotatably installed on the second support leg 702 through the rotating groove. A locking slot is provided on the threaded post 705, and the locking pin 703 is connected to the threaded post 705 through the locking slot.

[0023] Specifically, by rotating the second threaded sleeve 706 to disengage it from the long frame 605, the handle 707 can rotate around the second pivot 704. When the handle 707 rotates to a vertical position, the locking pin 703 can be inserted into the slot to limit the handle 707 and keep it in a vertical position. The vertical handle 707 can support the stretcher and prevent the patient from contacting the wet ground.

[0024] Working principle: After the entire device is folded up, the user can carry it on their back using the shoulder straps 3, facilitating rescue missions in mountainous environments. The long frame 605 can rotate around the first pivot 603, causing it to unfold. Once unfolded to a horizontal position, the long frame 605 aligns with the short frame 601. After alignment, the first threaded sleeve 604 can be rotated to thread the long frame 605 and the short frame 601 together, thus securing them. This provides a stable frame structure for the stretcher pad 1, facilitating patient transfer. Simultaneously, after the second threaded sleeve 706 is rotated to disengage from the long frame 605, the handle 707 can be rotated around the second pivot 704. When the handle 707 is rotated to a vertical position, the locking pin 703 can be inserted into the slot to limit the handle 707 and keep it in a vertical position. The vertical handle 707 can support the stretcher and prevent the patient from contacting the wet ground.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
