Description

Technical Field

[0001] This utility model relates to the field of stretcher technology, specifically a portable nursing stretcher. Background Technology

[0002] In medical emergency response, fire rescue, and outdoor rescue scenarios, the scoop stretcher is an essential piece of equipment for the rapid transfer of the injured and sick. Its detachable design and ease of use in confined spaces make it widely applicable in various emergency rescue operations. Its core function is not only to provide stable support for the injured and sick, preventing further injury due to changes in body position during transport, but also to possess flexible extension and adjustment capabilities to accommodate the body support needs of injured and sick individuals of different heights and body types, while simultaneously meeting the requirements for the overall length of the stretcher for storage and use in different rescue scenarios. Existing shovel stretchers typically consist of two symmetrical shovels. The length of the two shovels is adjusted via a telescopic structure. The locking and unlocking of the telescopic structure relies on locking mechanisms located on both sides of the stretcher. Specifically, when the shovel stretcher needs to be telescopically adjusted, the operator must first unlock the locking structures on both sides of the stretcher. After unlocking the locking structures on both sides, the operator must pull or push the shovels on both sides according to the actual needs to adjust the stretcher to the appropriate length. After the length adjustment is completed, the locking structures on both sides must be relocked. This operation method, which requires unlocking and adjusting the locking mechanisms on both sides separately and then relocking them, is problematic in emergency rescue scenarios where time is often extremely tight. The cumbersome unlocking and locking steps can prolong stretcher preparation time, potentially delaying the best treatment opportunity for the injured and reducing rescue efficiency.

[0003] In view of the above, this application is hereby submitted. Utility Model Content

[0004] The purpose of this invention is to provide a portable nursing stretcher to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides a portable nursing stretcher, including a left and right split frame, on which multiple stretchers are installed. The left and right split frame includes a symmetrically arranged left shovel frame and a right shovel frame. The left shovel frame and the right shovel frame can be separated or joined together to be inserted from both sides of the patient's body or spliced ​​into a complete load-bearing structure. The left shovel frame includes a left sleeve rod, one end of which is slidably connected to a left sliding rod, and the outwardly extending end of the left sliding rod is connected to a left support rod; The right shovel frame includes a right sleeve rod, one end of which is slidably connected to a right sliding rod, and the outwardly extending end of the right sliding rod is connected to a right support rod; Both the left and right slide rods are equipped with spring pins. The left slide rod is locked to the left sleeve rod by the spring pin, and the right slide rod is locked to the right pin hole by the spring pin. The left and right shovel frames are also equipped with adjustment structures to control the movement of the spring pins to engage the locking mechanism.

[0006] Furthermore, the ends of the left sleeve rod and the left support rod away from the left slide rod are each equipped with an insertion rod, and the ends of the right sleeve rod and the right support rod away from the right slide rod are each provided with a insertion hole for inserting the insertion rod. A pin is installed on the wall of the insertion hole, and a through hole is provided on the insertion rod for inserting the pin.

[0007] Furthermore, the spring pin includes a locking pin disposed on the left slide rod and the right slide rod, the locking pin being able to slide radially along the left slide rod and the right slide rod, the left sleeve rod having a left pin hole for the locking pin to engage, the right sleeve rod having a right pin hole for the locking pin to engage, and a return spring being installed inside the left slide rod and the right slide rod to push the locking pin outward to engage inside the left pin hole and the right pin hole.

[0008] Furthermore, there are several left and right pin holes, with several left pin holes equidistantly arranged along the axial direction of the left sleeve rod and several right pin holes equidistantly arranged along the axial direction of the right sleeve rod. The left and right pin holes are at the same height.

[0009] Furthermore, the adjustment structure includes a steel wire rope. The left support rod and the left slide rod have a first rope-passing channel formed inside for the steel wire rope to pass through. The right support rod and the right slide rod have a second wire-passing channel formed inside for the steel wire rope to pass through. The steel wire rope passes through the first rope-passing channel and the second wire-passing channel. One end of the steel wire rope is connected to a locking pin. The other end of the steel wire rope located in the first wire-passing channel is connected to a male buckle. The other end of the steel wire rope located in the second wire-passing channel is connected to a female buckle.

[0010] Furthermore, the surface of the support plate is provided with an anti-slip frosted texture, and the edges of the support plate are rounded.

[0011] Furthermore, both the end of the left slide rod inserted into the left sleeve rod and the end of the right slide rod inserted into the right sleeve rod are rotatably connected to a hinge rod. The other end of the hinge rod is hinged to a slide block, which is limited to slide inside the left and right sleeve rods.

[0012] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the adjusting structure incorporates a steel wire rope that passes through the rope channel between the left and right shovel frames. One end connects to the male and female buckles of the control end, while the other end connects to the locking pins of the sliding rods on both sides. The operator only needs to pull a single buckle to simultaneously pull the locking pins of the left and right sliding rods via the steel wire rope, compressing the return spring and unlocking both sides synchronously. After adjusting the length and releasing the buckle, the return spring can push the locking pins to simultaneously engage with the corresponding pin holes, achieving synchronous locking on both sides. This significantly shortens stretcher preparation time, avoids delays in treatment due to cumbersome operations during emergency rescues, and reduces operational difficulty, making it suitable for rescuers of all experience and physical strength to quickly master.

[0013] In this invention, the sliding block is limited to slide inside the left and right sleeve rods, which can prevent the sliding rods from shifting or jamming during extension and retraction, ensuring a smooth adjustment process. In addition, when the sliding block is pulled to the extreme position inside the left and right sleeve rods, the sliding block cannot be pulled out from inside the left and right sleeve rods, while the left and right sliding rods can be fully extended. Thus, when not in use, the left stretcher, left sliding rod, right stretcher, and right sliding rod can be folded above the left and right sleeve rods, reducing the overall size of the stretcher and making it easier to carry.

[0016] 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.

[0017] Please see Figures 1-5 This utility model provides a technical solution: a portable nursing stretcher, including a left and right split frame, with multiple stretchers 3 installed on the frame. The left and right split frame includes a left shovel frame 1 and a right shovel frame 2 arranged symmetrically. The left shovel frame 1 and the right shovel frame 2 can be separated or joined together to be inserted from both sides of the patient's body or spliced ​​into a complete load-bearing structure. The left shovel frame 1 includes a left sleeve rod 11, one end of which is slidably connected to a left slide rod 13, and the outwardly extending end of the left slide rod 13 is connected to a left support rod 12. The right shovel frame 2 includes a right sleeve rod 21, one end of which is slidably connected to a right sliding rod 23, and the outwardly extending end of the right sliding rod 23 is connected to a right support rod 22. Both the left slide rod 13 and the right slide rod 23 are equipped with spring pins. The left slide rod 13 is locked to the left sleeve rod 11 by the spring pin, and the right slide rod 23 is locked to the right pin hole 24 by the spring pin. The left shovel frame 1 and the right shovel frame 2 are also equipped with adjustment structures to control the movement of the spring pins to engage the lock.

[0018] The left and right split frame consists of a symmetrical left shovel frame 1 and a right shovel frame 2. The two can be separated to facilitate insertion into narrow spaces from both sides of the wounded or spliced ​​together to form a complete load-bearing structure. The stretcher 3 is installed on the frame to form a support surface for the wounded. Telescopic structure: The left sleeve rod 11 of the left shovel frame 1 is slidably inserted into the left slide rod 13, and the extended end of the left slide rod 13 is connected to the left stretcher 12; the right sleeve rod 21 of the right shovel frame 2 is slidably inserted into the right slide rod 23, and the extended end of the right slide rod 23 is connected to the right stretcher 22. The stretcher length can be adjusted by the axial sliding of the slide rod in the sleeve rod. Locking and unlocking control: Both the left slide bar 13 and the right slide bar 23 are equipped with spring pins. The left slide bar 13 is locked to the left sleeve bar 11 by the spring pin, and the right slide bar 23 is locked to the right pin hole 24 by the spring pin. The adjustment structure on the left shovel frame 1 and the right shovel frame 2 can control the movement of the spring pins to realize the locking and unlocking for easy extension or locking reset to ensure load stability.

[0019] As a technical optimization of this utility model, the ends of the left sleeve rod 11 and the left support rod 12 away from the left slide rod 13 are each equipped with an insertion rod 15, and the ends of the right sleeve rod 21 and the right support rod 22 away from the right slide rod 23 are each provided with a socket for the insertion rod 15 to be inserted. A pin 25 is installed on the wall of the socket, and a through hole 16 is provided on the insertion rod 15 for the pin 25 to be inserted.

[0020] Specifically, when the left shovel frame 1 and the right shovel frame 2 are closed, the insertion rod 15 is inserted into the insertion hole, and the pin 25 automatically engages with the through hole 16, forming a mechanical limit to prevent the frame from separating after splicing.

[0021] As a technical optimization of this utility model, the spring pin includes a locking pin 4 disposed on the left slide rod 13 and the right slide rod 23. The locking pin 4 can slide radially along the left slide rod 13 and the right slide rod 23. A left pin hole 14 is provided on the left sleeve rod 11 for the locking pin 4 to be inserted into, and a right pin hole 24 is provided on the right sleeve rod 21 for the locking pin 4 to be inserted into. A return spring 5 is also installed inside the left slide rod 13 and the right slide rod 23 to push the locking pin 4 to slide outward and be inserted into the left pin hole 14 and the right pin hole 24.

[0022] Specifically, the return spring 5 is installed inside the left slide bar 13 and the right slide bar 23. Under normal conditions, it pushes the locking pin 4 to slide outward, so that it is locked into the left pin hole 14 and the right pin hole 24 to achieve telescopic locking. When the adjustment structure applies external force, the locking pin 4 compresses the return spring 5, disengages from the pin hole, and releases the lock.

[0023] As a technical optimization of this utility model, a number of left pin holes 14 and right pin holes 24 are provided. The number of left pin holes 14 are arranged equidistantly along the axial direction of the left sleeve rod 11, and the number of right pin holes 24 are arranged equidistantly along the axial direction of the right sleeve rod 21. The height positions of the left pin holes 14 and the right pin holes 24 are equal.

[0024] Specifically, when adjusting the stretcher length, the locking pin 4 can be engaged with the pin hole at different positions to achieve multiple length adjustments; the equal height positions ensure that the left slide bar 13 and the right slide bar 23 extend and retract synchronously, avoiding one side being too long or too short.

[0025] As a technical optimization of this utility model, the adjustment structure includes a steel wire rope 6. The left support rod 12 and the left slide rod 13 have a first rope-passing channel formed inside for the steel wire rope 6 to pass through. The right support rod 22 and the right slide rod 23 have a second wire-passing channel formed inside for the steel wire rope 6 to pass through. The steel wire rope 6 passes through the first rope-passing channel and the second wire-passing channel. One end of the steel wire rope 6 is connected to the locking pin 4. The other end of the steel wire rope 6 located in the first wire-passing channel is connected to the male buckle 7. The other end of the steel wire rope 6 located in the second wire-passing channel is connected to the female buckle 8.

[0026] Specifically, the wire rope 6 is threaded through two types of channels. One end is connected to the locking pin 4, and the other end is connected to the male buckle 7 located in the first rope threading channel and the female buckle 8 located in the second wire threading channel. When the male buckle 7 or the female buckle 8 is pulled, the wire rope 6 pulls the locking pins 4 on both sides to compress the reset spring 5 simultaneously and release the lock. After being released, the reset spring 5 pushes the locking pin 4 to reset and lock.

[0027] As a technical optimization of this utility model, the surface of the support plate 3 is provided with anti-slip frosted texture, and the edges of the support plate 3 are provided with rounded corners.

[0028] Specifically, the surface of the stretcher 3 is provided with an anti-slip frosted texture to increase friction with the patient's clothing or body; the edges are rounded to eliminate sharp corners. During insertion and transfer, the anti-slip texture prevents the patient from sliding, and the rounded corners prevent scratching the patient's skin or clothing.

[0029] As a technical optimization of this utility model, the end of the left slide rod 13 inserted into the left sleeve rod 11 and the end of the right slide rod 23 inserted into the right sleeve rod 21 are both rotatably connected to the hinge rod 9. The other end of the hinge rod 9 is hinged to the slide block 10, which is limited to sliding inside the left sleeve rod 11 and the right sleeve rod 21.

[0030] Specifically, when the left slide bar 13 and the right slide bar 23 extend or retract, the slide block 10 slides directionally along the inner wall of the left sleeve bar 11 and the right sleeve bar 21, which serves as a guide. Since the slide block 10 cannot be pulled out from inside the left sleeve bar 11 and the right sleeve bar 21, while the left slide bar 13 and the right slide bar 23 can be fully extended, the left stretcher 12, the left slide bar 13, the right stretcher 22 and the right slide bar 23 can be folded above the left sleeve bar 11 and the right sleeve bar 21 when not in use, reducing the overall volume of the stretcher and making it easier to carry.

[0031] This portable nursing stretcher addresses the cumbersome unlocking and locking operation on both sides of existing scoop stretchers by optimizing the split frame structure and telescopic locking mechanism to achieve efficient and convenient patient transport. The specific working principle is as follows: The core load-bearing structure of the stretcher is a split frame consisting of a symmetrical left shovel frame 1 and a right shovel frame 2. The two can be completely separated. When the patient is in a narrow space such as under a bed or between seats, the operator can insert the left shovel frame 1 and the right shovel frame 2 parallel to each other from both sides of the patient's body until the stretcher plate 3 of the two shovel frames completely supports the patient's body. The non-slip frosted texture on the surface of the stretcher plate 3 can initially prevent the patient from sliding during insertion, and the rounded corner design of the edges can prevent scratches to the patient's skin or clothing, laying a safe foundation for subsequent splicing. Once the left shovel frame 1 and the right shovel frame 2 are in place, insertion rods 15 are installed at the ends of the left sleeve rod 11 and the left support rod 12 of the left shovel frame 1 that are away from the left slide rod 13. Correspondingly, insertion holes are opened at the ends of the right sleeve rod 21 and the right support rod 22 of the right shovel frame 2 that are away from the right slide rod 23. The operator pushes the left shovel frame 1 and the right shovel frame 2 closer together so that the insertion rods 15 are fully inserted into the insertion holes. At this time, the pins 25 on the wall of the insertion holes will be locked into the through holes 16 of the insertion rods 15, forming a two-way mechanical lock. This ensures that the left shovel frame 1 and the right shovel frame 2 become a complete load-bearing frame that cannot be moved relative to each other after being spliced ​​together, thus preventing the frames from separating during transportation. To address the length adjustment requirements, the left shovel frame 1 extends and retracts via the sliding connection between the left sleeve rod 11 and the left slide rod 13, while the right shovel frame 2 extends and retracts via the sliding connection between the right sleeve rod 21 and the right slide rod 23. The locking mechanism of both relies on a spring pin structure: the spring pin includes a locking pin 4 and a return spring 5. The locking pin 4 is respectively set on the left slide rod 13 and the right slide rod 23 and can slide radially. The left sleeve rod 11 has several equidistant left pin holes 14, and the right sleeve rod 21 has several equidistant right pin holes 24. The left pin holes 14 and the right pin holes 24 are at the same height, ensuring that the lengths on both sides change synchronously during extension and retraction. Unlocking process: The operator does not need to operate both sides separately. He only needs to pull the male buckle 7 at the end of the left support 12 or the female buckle 8 at the end of the right support 22. The male buckle 7 is connected to the locking pin 4 of the left slide rod 13 through the steel wire rope 6 in the first rope channel, and the female buckle 8 is connected to the locking pin 4 of the right slide rod 23 through the steel wire rope 6 in the second rope channel. When the buckle is pulled, the steel wire rope 6 will simultaneously pull the locking pins 4 on both sides to compress the return spring 5, so that the locking pins 4 are disengaged from the left pin hole 14 and the right pin hole 24, and the telescopic lock is released. Adjustment and locking process: After unlocking, push the left support rod 12 or the right support rod 22, causing the left slide rod 13 and the right slide rod 23 to slide along the axis of the sleeve rod. Adjust to a suitable length according to the height of the injured person. After adjustment, release the male buckle 7 or the female buckle 8. The return spring 5 pushes the locking pin 4 to pop out radially, re-engaging it into the corresponding left pin hole 14 and right pin hole 24, completing the simultaneous locking on both sides. In addition, the ends of the left slide rod 13 and the right slide rod 23 that are inserted into the left sleeve rod 11 and the right sleeve rod 21 are connected to the slide block 10 through the hinge rod 9. The slide block 10 is in The internal limiting sliding of the sleeve rod can prevent deviation and jamming during the extension and retraction of the slide rod, ensuring a smooth adjustment process. In addition, when the slide block 10 is pulled to the internal limit position of the left sleeve rod 11 and the right sleeve rod 21, the slide block 10 cannot be pulled out from inside the left sleeve rod 11 and the right sleeve rod 21, while the left slide rod 13 and the right slide rod 23 can be fully extended. Thus, when not in use, the left stretcher 12, the left slide rod 13, the right stretcher 22 and the right slide rod 23 can be folded above the left sleeve rod 11 and the right sleeve rod 21, reducing the overall size of the stretcher and making it easier to carry.
