Description

Technical Field

[0001] This invention relates to the field of nursing stretcher technology, and more specifically, to a portable outdoor nursing stretcher. Background Technology

[0002] Because commonly used stretchers are fixed in place and cannot be adjusted in size, rescuers cannot quickly move the injured through narrow passages or cramped stairwells in earthquake ruins when using them, which seriously affects the efficiency of rescue. Furthermore, when rescuers go to earthquake ruins or remote mountain areas, they need to carry a large amount of equipment and supplies. Although the commonly used stretchers can be folded, they can still only be carried by hand, which not only increases the burden on rescuers but also requires a large number of rescuers. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of commonly used stretchers, which are fixed in shape and cannot be adjusted in size. This makes it difficult for rescuers to quickly move the injured in narrow passages or confined spaces such as earthquake ruins, which seriously affects the efficiency of rescue. The invention provides a nursing stretcher that can be adjusted in size according to the body shape of the injured, making it easier for rescuers to lift the injured. The stretcher also has a folding function, making it easier for rescuers to carry and reducing their burden.

[0010] More preferably, it also includes a suspension assembly, with a suspension assembly for suspending medicine bottles connected to each single rod; the suspension assembly includes a plastic cap, a hanging rod, and a hanging strip; each connecting rod has an installation groove; a plastic cap is screwed onto the left end of each single rod; each single rod has a cavity; a hanging rod is placed in each cavity; a strip groove is formed on each hanging rod; an installation groove is provided at the bottom of each hanging rod; and a hanging strip is rotatably connected to each strip groove.

[0011] More preferably, the suspension assembly also includes a hanging bar; each bar groove is rotatably connected to the hanging bar via a torsion spring.

[0012] More preferably, each hanging strip has two hanging slots.

[0013] More preferably, a ball is provided on the upper part of the hanging rod.

[0014] More preferably, the outer surface of the hanging rod is provided with a rubber protective sleeve.

[0015] The beneficial effects are: The present invention provides a portable outdoor nursing stretcher designed as described above. By adjusting the position of the hooks on single poles one, two, and three and attaching them to the hanging holes on the canvas, the width of the canvas between single poles one, two, and three can be adjusted to accommodate injured persons of different body types. This makes it easier for rescuers to use the stretcher to quickly move the injured person through narrow passages in earthquake ruins or confined spaces such as stairwells, avoiding space constraints that could hinder the normal rescue of the injured.

[0016] The present invention provides a convenient portable outdoor nursing stretcher through the above design. By folding the stretcher, which consists of a single pole one, a connecting pole one, a single pole two, a connecting pole two, a single pole three, a canvas and a support plate, and then putting two shoulder straps on the shoulders, the folded stretcher can be carried on the back. This not only frees up the rescuer's hands and increases the rescuer's load-bearing capacity, but also makes it easier for the rescuer to carry the folded stretcher.

[0017] The present invention provides a portable outdoor nursing stretcher designed as described above. The support plate fixes the single bar one and single bar three of the folded stretcher, preventing the folded stretcher from continuously shaking on the rescuer's back. The rescuer can also quickly untie the fixed folded stretcher, thereby improving the ease of use of the stretcher and making it more convenient for rescuers to use. When a folded stretcher is carried on the back of a rescuer, the folded canvas acts like a backpack, allowing some supplies to be placed inside. By holding the supplies in place, the rescuer can carry more supplies, increasing the amount of supplies a person can carry and improving practicality.

[0018] The invention provides a portable outdoor nursing stretcher designed as described above. By hanging medicine bottles at a high place with a hanging strip, it is convenient to deliver the medicine into the body of the injured person. This eliminates the need to arrange a separate rescuer to follow the injured person at all times, freeing up a lot of manpower and improving rescue efficiency. By setting the hanging pole inside the single pole, the space of the single pole is used in a reasonable way, reducing the items carried by rescuers; When rescuers move the injured through rubble or in the wild, the glass medicine bottles hanging on the hanging rods will sway continuously. The rubber protective sleeves on the outer surface of the hanging rods protect the swaying glass medicine bottles from being hit and broken, which would affect the injured person's normal treatment.

Detailed Implementation

[0022] The various embodiments of the present invention will now be described with reference to the accompanying drawings. Furthermore, in the following figures, the scales of each layer and component have been schematically altered to make them easily identifiable. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to limit the specific scope of the invention.

[0023] Example 1: A portable outdoor nursing stretcher, such as Figures 1-5 As shown, there are two single poles, including pole 1. It also includes connecting rod 1 (2), single rod 2 (3), connecting rod 2 (4), single rod 3 (5), canvas 6, carrying assembly, and fixing assembly; each single rod 1 has a connecting rod 1 (2) hinged to its right side via a pivot; each connecting rod 1 (3) has a single rod 2 (3) hinged to its right side via a pivot; each single rod 2 (4) has a connecting rod 2 (4) hinged to its right side via a pivot; each single rod 2 (5) has six hooks arranged in a rectangular pattern on each single rod 1, single rod 2 (3), and single rod 3 (5); all the hooks on single rod 1, single rod 2 (3), and single rod 3 (5) are connected to canvas 6; canvas 6 has several arrayed hanging holes at its front and rear, and canvas 6 is connected to the hooks on single rod 1, single rod 2 (3), and single rod 3 (5) through the hanging holes; carrying assembly is connected to both single rods 2 (3); fixing assembly is connected to single rod 1 and single rod 3 (5).

[0024] Furthermore, in order to increase the friction of pole 1 and pole 3 5 for easier use by rescuers, each pole 1 and each pole 3 5 is equipped with a rubber sleeve 1001.

[0025] The carrying assembly includes a pivot 101 and a shoulder strap 102; the single rod 3 consists of a straight rod 3010 and two short rods 3011, with each end of the straight rod 3010 being rotatably connected to a short rod 3011 in a damped manner; a groove 3012 is provided on the right short rod 3011; the pivot 101 is rotatably connected to the groove 3012 by a torsion spring; the shoulder strap 102 is wound on the pivot 101; the other end of the shoulder strap 102 is fixedly connected to the left short rod 3011.

[0026] The fixing assembly includes a support plate 7, a slip ring 103, and a spring 104; each of the single rod 1 and each single rod 3 5 has an L-shaped groove 1002; the L-shaped grooves 1002 on the single rod 1 and the L-shaped grooves 1002 on the single rod 3 5 are symmetrically distributed from left to right; each L-shaped groove 1002 is slidably connected to a slip ring 103; each slip ring 103 is fixedly connected to a support plate 7; each L-shaped groove 1002 is provided with a spring 104, and the spring 104 is fixedly connected to the slip ring 103.

[0027] It also includes an anti-fall component, which is connected to the lower surface of the canvas 6; the anti-fall component includes a locking plate 201 and a safety belt 202; a locking plate 201 is fixedly attached to the left and right sides of the lower surface of the canvas 6; a safety belt 202 is fixedly attached to each locking plate 201.

[0028] The working steps of this embodiment are as follows: The following orientations are based on the viewpoint shown in the diagram, with the side marked 1001 on the rubber sleeve being the left side; The rotations described below refer to views from front to back, from top to bottom, and from right to left. Before transporting the injured, rescuers first remove the canvas 6 from the hooks of poles 1, 3, and 5. Then, based on the injured person's body shape, they adjust the position of the hooks on poles 1, 3, and 5 on the canvas 6, allowing for adjustment of the width of the canvas 6 between poles 1, 3, and 5 to accommodate injured persons of different body sizes. This facilitates rescuers using stretchers to quickly move the injured through narrow passages or confined spaces in earthquake ruins, avoiding spatial limitations that could hinder normal rescue efforts.

[0029] When rescuers are heading to the earthquake ruins or deep mountains for rescue operations, they can manually grasp the two support plates 7 and move them to the left along the slip rings 103 within the L-shaped grooves 1002 on the corresponding single rod 1. This forces the two springs 104 to compress until the two slip rings 103 are at the leftmost end of the corresponding L-shaped grooves 1002. Then, they can push the support plates 7 and the slip rings 103 to rotate within the L-shaped grooves 1002, causing the support plates 7 to lock at the end of the L-shaped grooves 1002. Next, the support plates 7 on the two single rods 3 5 are operated in the same way, locking them at the end of the L-shaped grooves 1002 on the single rods 3 5. Then, they can grasp the two single rods 1 1 and rotate them counterclockwise 90 degrees around the connecting rod 1 2, and then rotate the two connecting rods 1 2 around the single rod 2 3. Continue rotating counterclockwise by 90 degrees, folding the left side of canvas 6. Then, grasp the two single bars 35 and rotate them clockwise by 90 degrees around connecting bar 24. Next, rotate them clockwise by 90 degrees around single bar 23 with the two connecting bars 24 in the same direction, folding the right side of canvas 6. This completes the folding of the stretcher consisting of single bar 1, connecting bar 1, single bar 2, single bar 2, connecting bar 2, single bar 3, canvas 6, and support plate 7. Next, taking one of the single bars 23 as an example, rescuers grasp the two short bars 3011 and rotate them 180 degrees on the straight bar 3010. The short bars 3011 drive the pivot 101 and the carrying strap 102 to rotate together, rotating the carrying strap 102 to the outside of canvas 6. The other carrying strap 102 also rotates to the outside of canvas 6. Figure 5 As shown, at this time, the rescuers manually pull out the two shoulder straps 102 that are rolled up on the two rotating shafts 101, and then put the two shoulder straps 102 on their shoulders and carry the folded stretcher on their backs. This not only frees up the rescuers' hands and increases their load-bearing capacity, but also makes it easier for the rescuers to carry the folded stretcher. When rescuers carry a folded stretcher through rubble or the wilderness, they typically secure it with straps before carrying it on their backs. However, this causes the stretcher to sway continuously during movement, making it difficult for rescuers to carry. Furthermore, rescuers need to untie the straps to use the stretcher later, hindering quick deployment. Therefore, after folding the stretcher, rescuers can rotate the four support plates 7 on the corresponding single poles 1 and 3 5. This allows the support plate 7 on pole 1 to engage with the rubber sleeve 1001 on pole 3 5, and vice versa, securing the folded stretcher to prevent continuous swaying on the rescuer's back. This also allows rescuers to quickly untie the stretcher, improving its ease of use and making it more convenient for rescuers to use.

[0030] After rescuers place the injured person on a stretcher, the terrain of the ruins or wilderness is uneven and complex. When rescuers carry the injured person on the stretcher, it is easy for the injured person to sway or fall off the stretcher. Therefore, before the rescuers move, they can grab the two safety straps 202 on the lower surface of the canvas 6, let the two ends of the safety straps 202 go around the two single bars 1 to the top of the canvas 6, and then let the buckles at both ends of the safety straps 202 be closed and fixed together to tie the injured person on the canvas 6. This will prevent the injured person from falling off the stretcher or swaying during the transport process, which could cause secondary injury to the injured person.

[0031] It should be noted that when the folded stretcher is carried on the back of the rescuer, because the folded canvas 6 is backpack-shaped, some supplies can be placed inside the folded canvas 6. By holding the supplies in the canvas 6, the rescuer can carry more supplies, increase the amount of supplies a person can carry, and improve practicality.

[0032] Example 2, based on Example 1, such as Figures 5-7 As shown, it also includes a suspension assembly, with one suspension assembly connected to each single rod 1; the suspension assembly includes a plastic cover 301, a hanging rod 302, and a hanging strip 303; each connecting rod 4 has an installation groove 4001; a plastic cover 301 is screwed onto the left end of each single rod 1; each single rod 1 has a cavity 1003; a hanging rod 302 is placed in each cavity 1003; each hanging rod 302 has a strip groove 30201; each hanging rod 302 has an installation groove 30202 at its bottom; and a hanging strip 303 is rotatably connected to each strip groove 30201.

[0033] Furthermore, to facilitate the unfolding of the hanging strip 303 by rescuers, each strip groove 30201 is rotatably connected to the hanging strip 303 via a torsion spring.

[0034] Furthermore, to prevent the medicine bottle from sliding on the hanging strip 303, each hanging strip 303 has two hanging slots 30301.

[0035] Furthermore, in order to facilitate the removal of the hanging rod 302 from the cavity 1003, a ball 30203 is provided on the upper part of the hanging rod 302.

[0036] Furthermore, to prevent the glass medicine bottle from colliding with the hanging rod 302 when shaken, thus causing the glass medicine bottle to break, a rubber protective sleeve is provided on the outer surface of the hanging rod 302.

[0037] The working principle of this embodiment is as follows: In existing rescue operations, when a victim's injuries are too severe, intravenous fluid therapy is needed during transport to maintain their condition. To ensure the medication is delivered properly, a rescuer needs to constantly move alongside the victim and hold up the vial. However, this wastes the rescuer's time and energy, impacting the overall efficiency of the rescue operation. Therefore, a better solution is for the rescuer to remove the plastic cap 301 from the single pole 1, grasp the ball 30203 of the hanging pole 302, and remove the hanging pole 302 from the cavity 1003, thus detaching the hanging pole 302 from the cavity. After step 1003, under the action of the torsion spring on the hanging bar 303, the hanging bar 303 will automatically pop out from the strip groove 30201 and unfold horizontally. Then, the rescuer grabs the mounting groove 30202 of the hanging rod 302 and rotates it against the mounting groove 4001 to fix the hanging rod 302 to the connecting rod 4. Then, the rescuer hangs the infusion bottle in the hanging groove 30301 of the hanging bar 303. The bottle is suspended high by the hanging bar 303, which makes it easy to deliver the medicine to the injured person. This eliminates the need to arrange a separate rescuer to follow the injured person at all times, freeing up a lot of manpower and improving rescue efficiency.

[0038] After the rescuers have transferred the injured person, they remove the hanging rod 302 from the connecting rod 2 4, and then place the hanging rod 302 into the cavity 1003 with the ball 30203 facing outward and the mounting groove 30202 facing inward. During the movement of the hanging rod 302, it will force the hanging bar 303 to swing around the torsion spring and return to the strip groove 30201. Then, the plastic cover 301 is installed on the single rod 1 to seal the cavity 1003 and prevent the hanging rod 302 from falling out of the cavity 1003. By setting the hanging rod 302 in the single rod 1, the space of the single rod 1 is used in a reasonable way, reducing the items carried by the rescuers.

[0039] It should be noted that when rescuers move the injured person through the ruins or in the wild, the glass medicine bottle hanging on the hanging bar 303 will continue to sway. The rubber protective sleeve on the outer surface of the hanging bar 302 protects the swaying glass medicine bottle from being hit and broken, which would affect the injured person's normal treatment.

[0040] The above embodiments are provided for those skilled in the art to implement or use the present invention. Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope that conforms to the innovative features mentioned in the claims.
