Description

Technical Field

[0001] The invention relates to the technical field of stretchers, in particular to an outdoor simple stretcher and a storage method. Background Art

[0002] Outdoor simple stretchers are medical equipment designed specifically for emergency rescue missions in outdoor environments. This type of stretcher is usually lightweight, durable, easy to carry, and adaptable to a variety of terrains, to ensure that the wounded can be quickly and safely transferred to a safe area or medical institution in an outdoor environment. Stretchers play a very important role in first aid. It is a device that can safely and conveniently carry the wounded and is suitable for various situations, such as fires, earthquakes, traffic accidents, etc. The design of the stretcher usually takes into account the comfort and safety of the wounded and the convenience of carrying. Existing stretchers, such as the stretcher disclosed in announcement number CN106539651B, are composed of a frame rod and a stretcher cloth, and also include a plurality of straps, which are fastened to the patient lying on the stretcher cloth by Velcro adhesion.

[0003] At present, when the simple stretcher used in the prior art is involved in disaster relief or outdoor search and rescue, the terrain is relatively complex due to natural formation or is affected by earthquakes and floods, so the rescuers need to take their own safety into consideration when carrying the stretcher. At the same time, in earthquake and flood rescue, in addition to carrying a stretcher, the rescuers also need to carry emergency rescue supplies and medical drugs with them. The carry-on supplies are heavy, and the length of a conventional stretcher is generally 2-2.1 meters and the width is 50-55 cm. The length of the entire stretcher is for a complex rescue environment, especially for search and rescue in some outdoor forests with dense tree trunks. The larger the space occupied, the more limited the rescuers' ability to move will be, which is not conducive to efficient rescue. Summary of the invention

[0004] The purpose of the present invention is to provide a simple outdoor stretcher to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions: an outdoor simple stretcher, comprising a stretcher, the stretcher having a stretcher cloth and a plurality of short rods, the plurality of short rods being equally divided into two groups, the two groups of short rods being respectively rotatably arranged on the bottom walls on both sides of the stretcher cloth;

[0006] The short rod is a hollow structure, a T-shaped connecting rod is slidably inserted in the hollow structure, the end of the T-shaped connecting rod can slide out of one end of the short rod, and the other end of the short rod is provided with a plug hole connected to the hollow structure;

[0007] When the same group of multiple short rods are rotated to be coaxially distributed, the end of the T-shaped connecting rod can extend out of the hollow structure of the short rod and be inserted into the insertion hole of an adjacent short rod to form a long rod;

[0008] When the end of the T-shaped connecting rod slides in the opposite direction and leaves the insertion hole, the same group of multiple short rods can rotate to be parallel and perpendicular to the long side walls of the stretcher cloth, thereby facilitating the retraction of one short side wall of the stretcher cloth toward the other short side wall.

[0009] In a further embodiment, the side walls of both long sides of the stretcher cloth are provided with a plurality of small holes, an I-shaped hollow sleeve is fixedly embedded in the small holes, and an I-shaped block rotatably connected to the I-shaped hollow sleeve is rotatably provided on the upper side wall of one end of the short rod.

[0010] In a further embodiment, when the same group of multiple short rods can be rotated to be parallel distributed, the ends of two short rods in the two groups of short rods located in the same vertical plane that are close to each other are spherical structures, and magnet blocks are embedded in the spherical structures, and the magnetic poles of the magnet blocks of the two spherical structures are arranged with different sides.

[0011] In a further embodiment, reinforcing cross bars parallel to the short side walls are fixed to the upper ends of the two short side walls of the stretcher cloth.

[0012] In a further embodiment, two handles 1 are further included, and a T-shaped rod is fixed to the end side wall of the handle 1, and the T-shaped rod is threadedly connected to a short rod insertion hole below one of the short side walls of the stretcher cloth.

[0013] In a further embodiment, when the T-shaped connecting rod rotates in the positive direction along the axial direction of the hollow structure, the end of the T-shaped connecting rod can slide out of one end of the short rod away from the insertion hole and be inserted into the insertion hole of an adjacent short rod.

[0014] In a further embodiment, when the T-shaped rod rotates in the opposite direction along the axial direction of the hollow structure, the T-shaped connecting rod loses the thrust for sliding out of the hollow structure.

[0015] In a further embodiment, the sliding sleeve on the outer wall of the T-link is provided with a spring and a sliding disk located in the hollow structure, one end of the spring is connected to the side wall of the sliding disk, and the other end is connected to the side wall of one end of the T-link located in the hollow structure.

[0016] In a further embodiment, a second handle is provided at the end of the short rod below the other short side wall of the T-shaped insertion rod and the stretcher cloth.

[0017] Preferably, the present invention further discloses a method for storing an outdoor simple stretcher, comprising the following steps:

[0018] A1. When in use, the stretcher cloth is erected vertically, with the second handle at the bottom and the first handle at the top. At this time, the short rods will rotate to a vertical state around the rotation position of the I-shaped block under their own weight, so that the same group of multiple short rods rotate to a coaxial distribution state. Then, the first handle is rotated to rotate and feed the T-shaped connecting rod along the hollow structure, and then the end of the T-shaped connecting rod is extended out of the hollow structure and inserted into the adjacent short rod insertion hole to form a long rod. The two groups of short rods are spliced ​​to form a long rod, which serves as the stretcher load-bearing rod. Only the two handles 1 and 2 are lifted upward to lift the rescued person lying on the stretcher cloth;

[0019] A2. When storing, rotate the handle in the opposite direction, the T-shaped connecting rod loses the thrust to slide out of the hollow structure, slide the end of the T-shaped connecting rod in the opposite direction to disengage from the socket, and rotate the same group of multiple short rods to be parallel and perpendicular to the long side wall of the stretcher cloth, then roll up one short side wall of the stretcher cloth to the other short side wall for storage, so as to shorten the length of the stretcher.

[0032] The following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Embodiment, this embodiment provides a simple outdoor stretcher, such as Figure 1 and Figure 4 As shown, the stretcher comprises a stretcher cloth 1 and a plurality of short rods 2, the plurality of short rods 2 are equally divided into two groups, and the two groups of short rods 2 are respectively arranged on the bottom walls of the two sides of the stretcher cloth 1 in a rotatable manner; specifically, a plurality of small holes are opened on the two long side walls of the stretcher cloth 1, and an I-shaped hollow sleeve 12 is fixedly embedded in the small holes, and an I-shaped block 21 rotatably connected to the I-shaped hollow sleeve 12 is rotatably arranged on the upper side wall of one end of the short rod 2. Figure 2 and Figure 3 As shown, the short rod 2 can be rotated and adjusted between being parallel to the long side wall of the stretcher cloth 1 and being perpendicular to the long side wall of the stretcher cloth 1 with the I-shaped block 21 as the rotation center.

[0034] It should be noted that if Figure 5 and Figure 6 As shown, the short rod 2 is a hollow structure, and a T-shaped connecting rod 22 is slidably inserted in the hollow structure. The T-shaped connecting rod 22 can slide back and forth along the axial direction of the hollow structure. The end of the T-shaped connecting rod 22 can slide out of one end of the short rod 2, and the other end of the short rod 2 is provided with a socket connected to the hollow structure. When the same group of multiple short rods 2 rotate to coaxial distribution, the end of the T-shaped connecting rod 22 can extend out of the hollow structure of the short rod 2 and insert into the socket of an adjacent short rod 2. At the same time, it can continue to push another T-shaped connecting rod 22 along the adjacent socket to continue to slide along the hollow structure and extend into the socket of the next short rod 2. All short rods 2 can be connected together to form a long rod. The stretcher cloth 1 can be lifted by holding the two ends of the long rod. When the end of the T-shaped connecting rod 22 slides in the opposite direction and leaves the socket, the same group of multiple short rods 2 can rotate to be parallel and perpendicular to the long side wall of the stretcher cloth 1, thereby facilitating the reeling of one short side wall of the stretcher cloth 1 toward the other short side wall.

[0035] At the same time Figure 5 and Figure 6 As shown, two handles 3 are also included, and a T-shaped plug rod 31 is fixed to the end side wall of the handle 3. The T-shaped plug rod 31 is threadedly connected to the short rod 2 insertion hole below one of the short side walls on the stretcher cloth 1. When the T-shaped plug rod 31 rotates forward along the axial direction of the hollow structure, the end of the T-shaped connecting rod 22 can slide out of the end of the short rod 2 away from the insertion hole and insert into the insertion hole of an adjacent short rod 2. When the T-shaped plug rod 31 rotates in the opposite direction along the axial direction of the hollow structure, the T-shaped connecting rod 22 loses the thrust to slide out of the hollow structure.

[0036] like Figure 7 As shown, a handle 2 4 is provided at the end of the short rod 2 below the T-shaped insertion rod 31 and the other short side wall of the stretcher cloth 1. The two handles 2 4 can cooperate with the two handles 1 3 as four force holding points, and only two people are needed to lift the entire stretcher upward.

[0037] For example, in addition to carrying a stretcher, emergency rescue supplies and medical treatment drugs are also needed, and the load of portable supplies is relatively large. Therefore, when rescuers are in outdoor rescue conditions with relatively complex terrain, the more items they carry and the more space they take up, the more unfavorable it will be for the rescuers' search and rescue work. In order to minimize the space occupied by the stretcher, the stretcher can be stored when it is carried at any time. The specific operation is to roll up the entire stretcher into a Fig. 9 In the state shown, i.e., the handle 3 is rotated in the reverse direction, the T-type connecting rod 22 loses the thrust to slide out of the hollow structure. In order to quickly slide the end of the T-type connecting rod 22 in the reverse direction and disengage from the socket, a spring 25 and a sliding disk 24 located in the hollow structure are provided on the outer wall of the T-type connecting rod 22. One end of the spring 25 is connected to the side wall of the sliding disk 24, and the other end is connected to the side wall of one end of the T-type connecting rod 22 located in the hollow structure. When the T-type connecting rod 22 loses the thrust to slide out of the hollow structure, the elastic force of the spring 25 is used to slide the T-type connecting rod 22 deep into the hollow structure, so that the entire T-type connecting rod 22 can be completely stored in the hollow structure, thereby disengaging the end of the T-type connecting rod 22 from the corresponding socket. Subsequently, the two groups of multiple short rods 2 are rotated to a state of being parallel to each other and perpendicular to the long side wall of the stretcher cloth 1. The stretcher cloth 1 is made of canvas material, which is both strong and foldable. Then one short side wall of the stretcher cloth 1 is rolled up toward the other short side wall to shorten the length of the stretcher. Fig. 9 In the rolled-up state shown, the rolled-up stretcher cloth 1 can be tied up with a strap and can be carried diagonally across the body or on the back.

[0038] When in use, the stretcher cloth 1 is erected vertically. Figure 8In the state shown, the relative vertical state is maintained as much as possible, with handle 2 4 located at the lower side and handle 1 3 located at the upper side. At this time, the short rod 2 will rotate to a vertical state around the rotation position of the I-shaped block 21 due to its own weight, so that the same group of multiple short rods 2 rotate to a coaxial distribution state, and then the handle 1 3 is rotated to rotate and feed the T-shaped connecting rod 22 along the hollow structure, and then the end of the T-shaped connecting rod 22 is extended out of the hollow structure and inserted into the adjacent short rod 2 socket, and another T-shaped connecting rod 22 can be pushed along the adjacent socket to continue to slide along the hollow structure and extend out and insert into the socket of the next short rod 2, so that all short rods 2 can be connected together to form a long rod. Two groups of short rods 2 are spliced ​​to form a long rod, which serves as a stretcher load-bearing rod. Only two handles 1 3 and two handles 2 4 need to be lifted upward to lift the rescued person lying on the stretcher cloth 1 for transfer.

[0039] In summary, the above structure can be rolled up before use, shortening the length of the entire stretcher, thereby reducing the space occupied, making it easier for rescuers to carry it outdoors, and is very suitable for rescue environments with complex terrain. When in use, the two sets of short rods 2 can be quickly unfolded and assembled together to form a load-bearing rod, making it convenient to lift the stretcher cloth 1 and transfer the rescued person.

[0040] In this embodiment, further, Figure 6 As shown, when the same group of multiple short rods 2 can be rotated to be parallel, the ends of the two short rods 2 located in the same vertical plane in the two groups of short rods 2 that are close to each other are spherical structures, and the spherical structures are embedded with magnet blocks 23, and the magnetic poles of the two spherical magnet blocks 23 are set at different sides. When the two groups of short rods 2 are rotated to be parallel, the magnet blocks 23 at the ends of the two short rods 2 that are close to each other in the two groups of short rods 2 can be adsorbed to each other, so that when the stretcher cloth 1 is rolled up, the short rods 2 will not easily rotate around the I-shaped block 21, resulting in the stretcher cloth 1 being unable to be rolled up smoothly. Of course, the magnetic force of the magnet block 23 here cannot be too large, that is, once the stretcher is erected longitudinally, the component force of the short rod 2 rotating under its own weight must be greater than the magnetic force of the two magnet blocks 23 adsorbed together, so that when the stretcher is erected longitudinally, the same group of multiple short rods 2 can be smoothly turned over to maintain a coaxial distribution state, which is conducive to the T-shaped connecting rod 22 extending out and smoothly inserted into the jack.

[0041] In addition, since the stretcher cloth 1 is soft in texture, when the person being rescued lies on the stretcher cloth 1, once lifted, the middle part of the stretcher cloth 1 will sink, and at the same time drive the two load-bearing rods to move together, which is not convenient for the rescuer to apply force to move forward. For this reason, reinforcing cross bars 11 parallel to the short side walls are fixed at the upper ends of the two short side walls of the stretcher cloth 1, such as Figure 2As shown, two reinforcing cross bars 11 are used to support the stretcher cloth 1 horizontally, and when the rescued person is lifted up while lying on the stretcher cloth 1, the stretcher cloth 1 will not fall down seriously. In this way, after the rescuer holds the handle 1 3 and the handle 2 4 and lifts them upward, the distance between the two groups of load-bearing bars does not change. When the rescuer lifts them upward, there is no need to divide the force of the two groups of load-bearing bars horizontally, so as to avoid bringing additional load to the rescuer, which is not conducive to moving and transferring the rescued person in a complex terrain environment.

[0042] The present invention also discloses a storage method for an outdoor simple stretcher, comprising the following steps:

[0043] A1. When in use, the stretcher cloth 1 is vertically erected, with the handle 2 4 located at the lower side and the handle 1 3 located at the upper side. At this time, the short rod 2 is rotated to a vertical state around the rotation position of the I-shaped block 21 by its own weight, so that the same group of multiple short rods 2 are rotated to a coaxial distribution state. Then, the handle 1 3 is rotated to rotate and feed the T-shaped connecting rod 22 along the hollow structure, and then the end of the T-shaped connecting rod 22 is extended out of the hollow structure and inserted into the adjacent short rod 2 insertion hole to form a long rod. Two groups of short rods 2 are spliced ​​to form a long rod as a stretcher load-bearing rod. Only the two handles 1 3 and the two handles 2 4 need to be lifted upward to lift the rescued person lying on the stretcher cloth 1 for transfer.

[0044] A2. When storing, the handle 3 is rotated in the reverse direction, and the T-shaped connecting rod 22 loses the thrust to slide out of the hollow structure. The end of the T-shaped connecting rod 22 is slid in the reverse direction to disengage from the insertion hole, and the same group of multiple short rods 2 can be rotated to be parallel and perpendicular to the long side wall of the stretcher cloth 1. Then, one short side wall of the stretcher cloth 1 is rolled up to the other short side wall for storage, thereby shortening the length of the stretcher.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
