Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of medical emergency devices, specifically to a foldable portable clinical medical emergency device. Background Technology
[0002] Stretchers are an indispensable tool in clinical emergency care. As a rescue tool, they allow for the transfer of injured persons by placing them on them. However, when workers in the field require emergency care, the terrain is often rugged, uneven, and complex, with some areas inaccessible by vehicles. Emergency responders, after arriving near the accident site by car, often have to walk to the location. Emergency personnel typically carry medical equipment and supplies in backpacks, but when retrieving a stretcher, the long frame and non-foldable structure make it difficult to carry independently. Usually, two people are needed to lift the stretcher to the scene, a time-consuming and laborious process. While some stretchers are foldable, they lack a skeletal support structure, resulting in poor stability and a tendency to dent inwards, posing a risk of secondary injury to the patient. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a foldable portable clinical medical emergency device.
[0004] This utility model discloses a foldable portable clinical medical emergency device, comprising two parallel central support plates. A mounting base is located at the center of the top surface of each central support plate. Symmetrically arranged on both sides of the mounting base are stretcher support rods that are rotatably connected to it. The end of each stretcher support rod away from the mounting base has a grip with anti-slip texture. Two third ear-shaped seats are symmetrically arranged at the adjacent ends of the two mounting bases. A stretcher cloth for supporting the injured person is fixedly covered at the bottom of the four stretcher support rods, adhering to the bottom surface of the central support plates. A first support structure for supporting the patient's back or legs is located below the stretcher cloth between two stretcher support rods on the same side. The two first support structures on both sides are arranged in a mirror image. A second support structure for supporting the patient's buttocks is located below the stretcher cloth between the two mounting bases.
[0005] Furthermore, a first ear seat is provided on the side of the stretcher support rod that is close to the mounting base. The first ear seat is rotatably connected to a second ear seat installed on the side wall of the mounting base via a hinge shaft. The length of the mounting base is less than the length of the central support limiting plate.
[0006] Furthermore, the first support structure includes two fourth ear seats installed on the inner side of the stretcher support rods. A first stop block is provided on the side of the fourth ear seat that is close to the middle support limiting plate and installed on the stretcher support rod. The fourth ear seats on the two stretcher support rods on the same side are each equipped with a first connecting support plate that is rotatably connected to them via a hinge. The ends of the two first connecting support plates that are far from the fourth ear seats are respectively fitted and limited on the connecting limiting shaft cut out in the circumferential section on the connecting column. The first connecting support plate and the connecting limiting shaft are rotatably connected. Drive rods are fixedly installed on the two connecting columns on the same side. The ends of the two drive rods that are close to each other are respectively installed with the first self-locking structure and the second self-locking structure.
[0007] Furthermore, the second support structure includes two fifth ear seats symmetrically mounted on the drive rod. Each fifth ear seat is fitted with a second connecting support plate via a hinge shaft. The end of the second connecting support plate away from the fifth ear seat is rotatably connected to a third ear seat assembly on the same side and end via a hinge shaft. The third ear seat assembly is rotatably connected to the mounting base via a T-shaped rotating boss mounted at its end.
[0008] Furthermore, the first self-locking structure includes a fixed cone plate with an inclined surface and an overall cross-section of an isosceles trapezoid installed at the end of a drive rod. A sliding cone plate is provided on the drive rod and is slidably connected to it. A second stop block is provided on the drive rod to limit the sliding cone plate. The sliding cone plate is located between the second stop block and the fixed cone plate. The sliding cone plate and the fixed cone plate are the same size and arranged in opposite directions.
[0009] Furthermore, the second self-locking structure includes a locking platform installed at the end of another drive rod. The locking platform has a locking groove on its side near the fixed cone plate, allowing it to slide and engage with the fixed cone plate. Two sliding cavities are symmetrically formed within the locking platform. Each sliding cavity contains a limiting plate that slides and engages with it. The locking plate is installed at the middle of the end of the limiting plate near the locking groove. One end of the locking plate extends into the locking groove to limit the movement of the fixed cone plate. A guide slope is formed on the side of the locking plate near the first self-locking structure. A spring is installed within the sliding cavity, located between the limiting plate and the inner wall of the sliding cavity, to push the locking plate into the locking groove.
[0010] The beneficial effects of this utility model after adopting the above structure are as follows: It uses a first support structure and a second support structure to provide segmented support for the back, legs, and buttocks of the injured person on the stretcher, thereby preventing the stretcher from becoming too soft and collapsing inward, which could lead to secondary injury to the patient. Simultaneously, the first and second self-locking structures provide self-locking stability to the formed stretcher, ensuring its stability during use. Simultaneously, four rotating and cooperating stretcher support rods support the stretcher fabric, and the central bearing limiting plate limits the four stretcher support rods, ensuring the stability of the stretcher during folding while maintaining its stability. Furthermore, the rotating first and second connecting support plates allow the folded stretcher to retract inward, further reducing its volume and making it easier for a single person to carry, thus improving the rescue efficiency and reducing the labor intensity of rescue personnel.

A locking plate 24 is installed in the middle of the end of the limiting plate 23 near the locking groove 22. One end of the locking plate 24 extends into the locking groove 22 to limit the fixed cone plate 19. A guide slope is provided on the side of the locking plate 24 near the first self-locking structure. A spring 25 is provided in the sliding cavity 21. The spring 25 is located between the limiting plate 23 and the inner wall of the sliding cavity 21 to push the locking plate 24 into the locking groove 22.
[0028] The following, in conjunction with the accompanying drawings, further elaborates on the usage method and principle of the technical solution in this specific embodiment:
[0029] When using the stretcher, medical staff hold the two handles 2 on the same side and spread them outwards to flatten them. At this time, the stretcher support rod 1 abuts against the central support limiting plate 4 for limiting. Then, the medical staff pulls the two stretcher support rods 1 on the same end outwards simultaneously. At this time, the included angle between the two first connecting support plates 12 and the two second connecting support plates 16 gradually increases, and the near ends of the two drive rods 11 also gradually move closer together. Then, the medical staff can manually hold one drive rod 11 and push the fixed cone plate 19 into the locking groove 22 opened on the locking platform 20. At this time, the inclined surface of the fixed cone plate 19... First, the fixed cone plate 19 is continuously pushed into the sliding cavity 21, pressing the snap-fit plate 24 and the limiting plate 23 into the inclined surface of the snap-fit plate 24. At this time, the spring 25 is compressed. When the fixed cone plate 19 is pushed past the snap-fit plate 24, the spring 25 returns to its original position. At this time, the snap-fit plate 24 falls between the sliding cone plate 18 and the fixed cone plate 19. Then, the snap-fit plate 24 can restrict the fixed cone plate 19, and the drive rod 11 moving in two directions completes the fixed self-locking. The first stop block 10 can restrict the movement direction of the two first connecting support plates 12 corresponding to the position. At this time, the medical staff Personnel can transfer the injured person by flipping the entire stretcher so that the stretcher cloth faces upwards. Simultaneously, when the stretcher needs to be folded up, the staff pushes the drive rod 11, equipped with the fixed cone plate 19, a short distance into the locking groove 22. At this time, the sliding cone plate 18 enters the locking groove 22, and the guide slope of the locking plate 24 abuts against the sliding cone plate 18. Therefore, when the sliding cone plate 18 enters the locking groove 22, the guide slope of the locking plate 24 presses the locking plate 24 against the sliding cavity 21. After the sliding cone plate 18 passes the locking plate 24, the medical personnel pull out the device equipped with the fixed cone plate. Drive rod 11 of 19, and then with the sliding cone plate 18 and the locking plate 24 in contact, the sliding cone plate 18 slides along the drive rod 11 until it is in contact with the fixed cone plate 19. The drive rod 11 continues to move outward. At this time, the locking plate 24 retracts under the guidance of the inclined surface of the sliding cone plate 18. Since the sliding cone plate 18 and the fixed cone plate 19 are in contact, the locking plate 24 will transition from the inclined surface of the sliding cone plate 18 to the inclined surface of the fixed cone plate 19 after retracting to the top, thereby releasing the restriction on the fixed cone plate 19. Medical personnel can then reverse the above steps to retract and fold the stretcher again.
