Description

Technical Field

[0001] This utility model relates to the field of stretchers, and more specifically, to a stretcher with a fixing mechanism. Background Technology

[0002] Stretchers are a common medical transport tool in hospitals. When some areas encounter emergencies, such as earthquakes or mudslides, ambulances cannot enter the disaster area to transport the injured due to road damage. The injured who need immediate rescue need to be carried by stretchers to specific places for medical treatment. Since the injuries of the injured are mostly external injuries or bone injuries, the stretcher sways a lot during the process of being carried by stretcher due to the uneven road, which increases the patient's pain. Therefore, conventional stretchers are mostly made of relatively soft fabric. However, in practical applications, it was found that because the support surface of conventional stretchers is relatively soft, the patient's body will directly contact the ground after lying on it, which can easily cause secondary injury to the patient. Therefore, we made improvements and proposed a stretcher with a fixing mechanism. Summary of the Invention

[0003] The purpose of this invention is to provide a stretcher with a fixed mechanism, which solves the problem that existing stretchers with fixed mechanisms cannot provide overall support for patients when they are lying down.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: A stretcher with a fixing mechanism includes two parallel support rods, a stretcher pocket is provided on the surface of the two support rods, and each of the two support rods has a storage cavity inside, in which an auxiliary support structure is slidably provided; The auxiliary support structure includes a slider that is slidably disposed inside the storage cavity. A connecting seat is fixed on one side of the slider. A support leg is provided on the inner side of the connecting seat. A support shaft is movably mounted on the surface of the support leg and the surface of the connecting seat. The support leg can rotate along the support shaft. A limiting structure is provided on the surface of the connecting seat near the support shaft.

[0005] As a preferred technical solution of this application, the limiting structure includes a base fixed to the surface of the connecting seat, a positioning rod slidably disposed in the base, and a spring sleeved on the surface of the positioning rod and fixed to the base.

[0006] As a preferred technical solution of this application, the surface of the support shaft is provided with positioning holes, and there are multiple positioning holes. Each of the multiple positioning holes is adapted to the inner end of the positioning rod, and the inner end of the positioning rod can be engaged in the corresponding positioning hole by the spring force.

[0007] As a preferred technical solution of this application, a fixing post is fixed at the end of the support leg away from the connecting seat, the surface of the fixing post is provided with external threads, and the inner side of the support rod near the edge has internal threads that are compatible with the external threads.

[0008] As a preferred technical solution of this application, a handle is fixed to one end of the fixing column.

[0009] As a preferred technical solution of this application, the surface of the support rod is further fixed with a connector, and the surface of the connector is provided with a strap for fixing the patient's limb.

[0010] As a preferred technical solution of this application, the surface of the stretcher bag has a clearance at the position corresponding to the connector for the passage of the strap.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In the scheme of this application: The auxiliary support structure allows the support legs to be pulled out, exposing the support shaft. This allows the support legs to be flipped so that they form a 90-degree angle with the support rod, enabling the handles to be directly supported on the ground and suspending the stretcher basket. This avoids the patient's entire body directly contacting the ground, which could easily cause secondary injury. At the same time, the auxiliary support structure can be flipped back to its original position and stored in the storage cavity, leaving only the handles exposed, thus meeting the needs of a conventional stretcher for quick and portable transport.

[0019] like Figures 1-6 As shown, this embodiment proposes a stretcher with a fixing mechanism, including two parallel support rods 1, a stretcher pocket 2 is provided on the surface of the two support rods 1, and each of the two support rods 1 has a storage cavity 3 inside, and an auxiliary support structure 4 is slidably provided in the storage cavity 3. The auxiliary support structure 4 includes a slider 41 that is slidably disposed inside the storage cavity 3. The outer diameter of the tail end of the slider 41 is larger than the inner diameter of the storage cavity 3. This satisfies the requirement that the slider 41 slides inside the storage cavity 3 while preventing the slider 41 from sliding out completely. A connecting seat 42 is fixed to one side of the slider 41. A support leg 43 is provided on the inner side of the connecting seat 42. A support shaft 44 is movably mounted on the surfaces of the support leg 43 and the connecting seat 42. The support leg 43 can rotate along the support shaft 44. A limiting structure 5 is provided on the surface of the connecting seat 42 near the support shaft 44. The limiting structure 5 includes a base 51 fixed to the surface of the connecting seat 42, a positioning rod 52 slidably disposed in the base 51, and a spring 53 sleeved on the surface of the positioning rod 52 and fixed to the base 51. The surface of the support shaft 44 is provided with positioning holes 440. There are multiple positioning holes 440, and each of the multiple positioning holes 440 is adapted to the inner end of the positioning rod 52. Under the action of the spring 53, the inner end of the positioning rod 52 can be inserted into the corresponding positioning hole 440. The end of the support leg 43 away from the connecting seat 42 is movably connected to a fixing post 45. The fixing post 45 can rotate relative to the support leg 43 without falling off. The surface of the fixing post 45 is provided with an external thread 46. The inner side of the support rod 1 near the edge has an internal thread that matches the external thread 46. Rotating the fixing post 45 can make it form a threaded engagement with the inside of the support rod 1, thereby completing the overall positioning of the auxiliary support structure 4. A handle 47 is fixed to one end of the fixing post 45; The surface of the support rod 1 is also fixed with a connector 11, and the surface of the connector 11 is provided with a strap 12 for fixing the patient's limb; The surface of the stretcher pocket 2 has a clearance 13 at the position corresponding to the connector 11 for the passage of the strap 12; like Figure 1 and Figure 2 As shown, the stretcher is in its normal state at this time, allowing for direct lifting and rotation of the patient off the ground. When temporary support is needed for the patient (e.g., during treatment), the fixed column 45 can be rotated to separate it from the support rod 1, allowing the slider 41 to be pulled outwards. Once the support shaft 44 is exposed, the positioning rod 52 can be pulled, and the support leg 43 can be rotated. When the support leg 43 rotates to form a 90-degree angle with the support rod 1, the positioning rod 52 is released, and one end of it is engaged in the corresponding positioning hole 440 by the force of the spring 53, thus limiting the angle of the support leg 43. At this time, the stretcher basket 2 is suspended, and the patient on it will not directly contact the ground, thus avoiding the problem of secondary injury.

[0020] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
