Description

Technical Field

[0001] This utility model relates to the field of stretcher technology, and more specifically, to a folding emergency stretcher. Background Technology

[0002] The emergency medicine department or emergency medicine center is the department in the hospital with the highest concentration of critically ill patients, the most types of diseases, and the heaviest rescue and management tasks. Some patients are unable to walk on their own during the emergency process due to their own health conditions. In this case, in order to provide emergency care, medical staff will use a stretcher to place the patient on the stretcher and carry them to the emergency room for treatment.

[0003] However, most existing stretchers are folded and unfolded by hinges. While this method is convenient, it not only makes the stretcher less stable when unfolded, but also takes up a lot of space when folded, and it is inconvenient for medical staff to move the folded stretcher by themselves. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a folding emergency stretcher. Through the cooperation of the first adjustment mechanism and the second adjustment mechanism, the stretcher can be extended and retracted multiple times without the aid of hinges, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a folding emergency stretcher, comprising a woven fabric, wherein mounting blocks are symmetrically arranged on both sides of the woven fabric, and two first adjustment mechanisms are provided on the rear side of the woven fabric;

[0006] The first adjustment mechanism includes a mounting rod with two grooves inside. A first through hole is provided on both sides of the mounting rod. Several mounting slots are provided on the inner walls of the two grooves. A first threaded ring is provided inside the mounting slot.

[0007] In a preferred embodiment, the two first threaded rings are provided with threaded plates inside, and a connecting rod is provided on one side of the threaded plate, and a second through hole is provided inside the connecting rod.

[0008] In a preferred embodiment, a movable rod is provided inside the second through hole, one end of the movable rod is connected to the threaded plate, and the other end of the movable rod is provided with a rotating block.

[0009] In a preferred embodiment, a second adjustment mechanism is provided between the opposing connecting rods in the two adjustment mechanisms, and the second adjustment mechanism includes a fixed rod.

[0010] In a preferred embodiment, a screw is provided at the top of the fixing rod, a second threaded ring is provided on the screw, and a connecting plate is provided at the bottom of the screw and the top of the second threaded ring. The connecting plate is connected to its corresponding connecting rod, and a stop is provided at the top of one of the connecting plates. The bottom of the stop passes through its corresponding connecting plate and is connected to the screw.

[0011] In a preferred embodiment, a protective sleeve is provided at the bottom of the connecting rod, and a handle is provided inside the protective sleeve, the handle being connected to the connecting plate.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. By setting up a first adjustment mechanism, the stretcher can no longer be folded and stored by hinged connection, but can be retracted and stored with the help of the first adjustment mechanism. This storage method not only improves the stability of the stretcher during use, but also allows for quick storage by only one person.

[0014] 2. By setting a second adjustment mechanism, the stretcher can be extended and retracted again after being extended and retracted by the first adjustment mechanism. Through multiple extension and retraction settings, the stretcher becomes smaller after being retracted, which not only makes it easier for medical staff to move and carry the retracted stretcher, but also reduces the space required for the stretcher to be placed.

[0021] 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.

[0022] As attached Figure 1-5 The folding emergency stretcher shown includes a woven fabric 1, which provides a position for the patient to lie down. Mounting blocks 2 are symmetrically arranged on both sides of the woven fabric 1. The mounting blocks 2 restrict the position of the woven fabric 1 and connect the woven fabric 1 to the device. Multiple mounting blocks 2 are respectively connected to corresponding connecting rods 6. Two first adjustment mechanisms are provided on the rear side of the woven fabric 1.

[0023] The first adjustment mechanism includes a mounting rod 3, which has two grooves inside. A first through hole is provided on both sides of the mounting rod 3. Several mounting slots are provided on the inner walls of the two grooves. A first threaded ring 4 is installed inside each mounting slot. By installing the first threaded ring 4 in the mounting slot, the connecting rod 6 can smoothly enter the mounting rod 3. Threaded plates 5 are provided inside the two first threaded rings 4. The first threaded rings 4 and threaded plates 5 are matched to ensure smooth threaded connection between the threaded plates 5 and the first threaded rings 4. A connecting rod 6 is provided on one side of the threaded plate 5. A second through hole is provided inside the connecting rod 6. A movable rod 7 is provided inside the second through hole. The second through hole allows the movable rod 7 to rotate smoothly. One end of the movable rod 7 is connected to the threaded plate 5, and the other end of the movable rod 7 is provided with a rotating block 8. The rotating block 8 facilitates the rotation of the movable rod 7, thereby rotating the threaded plate 5.

[0024] As attached Figure 2 , 4 As shown, a second adjustment mechanism is provided between the opposing connecting rods 6 in the two adjustment mechanisms. The second adjustment mechanism includes a fixed rod 9, a screw 10 is provided at the top of the fixed rod 9, and a second threaded ring 11 is provided on the screw 10. The screw 10 and the second threaded ring 11 are matched so that the screw 10 can be smoothly threadedly connected to the second threaded ring 11. A connecting plate 12 is provided at the bottom of the screw 10 and the top of the second threaded ring 11. The position of the fixed rod 9 is restricted by the connecting plate 12. The connecting plate 12 is connected to its corresponding connecting rod 6. A stop block 13 is provided at the top of one of the connecting plates 12. The bottom of the stop block 13 passes through its corresponding connecting plate 12 and is connected to the screw 10. The addition of the stop block 13 restricts the movement distance of the connecting plate 12.

[0025] As attached Figure 1 , 2 As shown in Figure 3, a protective sleeve 14 is provided at the bottom of the connecting rod 6, and a handle 15 is provided inside the protective sleeve 14. The handle 15 is connected to the connecting plate 12. The handle 15 makes it easier for medical staff to lift the stretcher, and the addition of the protective sleeve 14 improves the grip comfort of the handle 15.

[0026] The working principle of this utility model is as follows: When it is necessary to store the stretcher composed of this device, firstly, rotate multiple rotating blocks 8 in sequence to drive the threaded plate 5 to rotate through the movable rod 7. After the threaded plate 5 moves out of the first threaded ring 4 it is connected to, push the connecting rod 6 to send the connecting rod 6 into the mounting rod 3. After being sent in a certain distance, the threaded plate 5 contacts another first threaded ring 4. At this time, rotate the rotating block 8 again to make the movable rod 7 drive the threaded plate 5 to rotate and connect with this first threaded ring 4. After the connection is completed, the first storage of the stretcher is completed. Then, rotate multiple second threaded rings 11 in sequence to turn the second threaded rings 11 off the screw 10. After the second threaded rings 11 are turned off, hold the mounting rod 3 in the two first adjustment mechanisms and move them in opposite directions to shorten the distance between the two first adjustment mechanisms. At this time, the second storage of the stretcher is completed. When using the stretcher, simply reverse the above steps.
