Abstract
Description
Technical Field
[0001] This utility model relates to the field of rescue equipment technology, and in particular to a rescue stretcher that can be converted from a reclining to a sitting position. Background Technology
[0002] As a key piece of medical equipment in the pre-hospital emergency care system, the emergency stretcher can safely and efficiently transport patients from the accident scene to an ambulance or medical institution. A standard emergency stretcher typically consists of the following core components: support armrests, a support surface, wheels, steering casters, and support frames. Existing emergency stretchers only provide a single supine function. For example, patients with spinal injuries who need to remain supine are well-suited to this type of stretcher. However, patients with minor injuries requiring simple bandaging do not need to be supine. For patients with breathing difficulties, such as heart failure, asthma, or pulmonary edema, a semi-sitting (sitting) position can reduce pulmonary congestion and improve breathing, which is a crucial resuscitation measure; therefore, this type of stretcher is not suitable. Furthermore, this type of stretcher requires at least two rescuers to carry it, which is difficult to adjust its position and direction of movement in narrow corridors, elevators, and other complex terrains, making transport inconvenient, increasing the workload of emergency personnel, and posing a risk of injury. Utility Model Content
[0003] In view of this, in order to solve the problems that current emergency stretchers can only provide a single lying function, which cannot be used for different injuries, and that the workload is high due to the need for two rescuers to carry them, the embodiments of this utility model provide an emergency stretcher that can be converted between lying and sitting positions.
[0004] An embodiment of this utility model provides a recumbent or seated ambulance stretcher, comprising:
[0005] The outer frame is rectangular, and two first rollers are respectively provided at the bottom two ends of the outer frame;
[0006] The system includes three reclining mats, which are slidably arranged sequentially along the height direction within the outer frame. The three reclining mats are rotatably connected in sequence. From top to bottom, the three reclining mats are the first reclining mat, the second reclining mat, and the third reclining mat. The outer frame is also provided with a first locking member and a second locking member. The bottom ends of the third reclining mat are respectively provided with two second rollers. When all three reclining mats slide downwards, the first locking member locks the second reclining mat, and the second locking member locks the third reclining mat. This causes the lower end of the first reclining mat to flip backward, the lower end of the second reclining mat to flip forward, and the lower end of the third reclining mat to flip backward, forming a trolley.
[0007] Furthermore, each of the lying mats is provided with a horizontally arranged sliding rod, which is rotatably connected to the lying mat. Both ends of the sliding rod are provided with sliding sleeves, and the two sliding sleeves are vertically slidably fitted onto the outer frame.
[0008] Furthermore, the cushion is provided with a horizontally arranged perforation, through which the sliding rod can rotatably pass.
[0009] Furthermore, both the first locking member and the second locking member include two fixed sleeves, which are fixedly fitted onto the outer frame, and the fixed sleeves can prevent the sliding sleeve from sliding.
[0010] Furthermore, the outer frame includes an upper connecting rod, a lower connecting rod, a left connecting rod, and a right connecting rod. The upper connecting rod and the lower connecting rod are parallel, and the left connecting rod and the right connecting rod are parallel. The two sliding sleeves at both ends of each sliding rod are slidably sleeved on the left connecting rod and the right connecting rod, respectively.
[0011] Furthermore, it also includes a fourth reclining pad, the lower end of which is connected to the bottom of the outer frame via a damping hinge, allowing the upper end of the fourth reclining pad to be flipped forward to a predetermined angle.
[0012] Furthermore, the first, second, and third sleeping mats are rectangular blocks of the same width, and the lengths of the first, second, and third sleeping mats increase sequentially.
[0013] Furthermore, the lower end of the third reclining mat is provided with a telescopic support rod, and the second roller is rotatably mounted on the lower end of the telescopic support rod.
[0014] Furthermore, the lower end of the first sleeping mat is hinged to the upper end of the second sleeping mat via a rotary joint, and the lower end of the second sleeping mat is hinged to the upper end of the third sleeping mat via a rotary joint.
[0015] Furthermore, the two top corners of the upper end of the outer frame are rounded, and the top corners are provided with rubber sleeves.
[0016] The beneficial effects of the technical solution provided by the embodiments of this utility model are as follows:
[0017] 1. This utility model discloses a reversible stretcher that can be used in both reclining and sitting positions. In the reclining position, three cushions are laid flat within the outer frame to form a supine position for the patient. In the sitting position, all three cushions are slid downwards, causing the first locking member to lock the second cushion, and the second locking member to lock the third cushion. This causes the lower end of the first cushion to flip backward, the lower end of the second cushion to flip forward, and the lower end of the third cushion to flip backward, forming a trolley for the patient to sit on. This allows for the use of a reclining position for transporting patients with spinal cord injuries, while a sitting position can be used for transporting patients with minor injuries requiring simple bandaging or those experiencing breathing difficulties. This meets the diverse needs of patients in different conditions, at different stages of treatment, and in different transport environments, improving the safety, comfort, and efficiency of medical care.
[0018] 2. This utility model provides a reversible stretcher that can be converted from a supine to a sitting position. When converted to a sitting position, it forms a trolley, which can be easily pushed and moved after the patient sits down. It can be completed by a single person, which significantly reduces the workload of emergency personnel and improves the overall rescue efficiency compared to the supine position, which requires at least two rescuers to work together. Furthermore, the sitting position is sometimes more convenient for rescuers to carry, support, or use special methods to move patients through narrow corridors, elevators, and other complex terrains, reducing the physical burden and risk of injury for rescuers.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0029] Please refer to Figure 1 and 2 An embodiment of this utility model provides a recumbent stretcher that can be converted from lying down to sitting up, including an outer frame 1 and three reclining pads.
[0030] The outer frame 1 is rectangular and is generally formed by welding stainless steel metal tubes. In this embodiment, the outer frame 1 includes an upper connecting rod 15, a lower connecting rod 16, a left connecting rod 17, and a right connecting rod 18. The upper connecting rod 15 and the lower connecting rod 16 are parallel, and the left connecting rod 17 and the right connecting rod 18 are parallel. The upper connecting rod 15, the lower connecting rod 16, the left connecting rod 17, and the right connecting rod 18 form a rectangle and are formed by welding to form the outer frame 1.
[0031] Two first rollers 6 are respectively provided at both ends of the bottom of the outer frame 1. The two first rollers 6 are arranged opposite each other at the rear of the bottom of the outer frame 1, and the two first rollers 6 can be supported on the ground at the same time.
[0032] The three reclining cushions are slidably arranged sequentially along the height direction within the outer frame 1, and from top to bottom, they are the first reclining cushion 2, the second reclining cushion 3, and the third reclining cushion 4. Here, the first reclining cushion 2, the second reclining cushion 3, and the third reclining cushion 4 are rectangular blocks of the same width, and their lengths increase sequentially. The width of the first reclining cushion 2, the second reclining cushion 3, and the third reclining cushion 4 is smaller than the width of the outer frame 1, thereby allowing the first reclining cushion 2, the second reclining cushion 3, and the third reclining cushion 4 to be positioned between the left connecting rod 17 and the right connecting rod 18.
[0033] Each of the aforementioned cushions can slide along its height, that is, along the length of the left connecting rod 17 or the right connecting rod 18. Specifically, each cushion is provided with a horizontally arranged sliding rod 20, which is rotatably connected to the cushion. Here, the cushion has a horizontally arranged through hole 19, through which the sliding rod 20 rotatably passes, allowing the cushion to rotate around the sliding rod 20. Each end of the sliding rod 20 is provided with a sliding sleeve 10, which is vertically slidably fitted onto the left connecting rod 17 and the right connecting rod 18 of the outer frame 1, allowing the cushion to slide along the left connecting rod 17 and the right connecting rod 18 via the two sliding sleeves 10 at both ends of the sliding rod 20.
[0034] The three reclining mats are rotatably connected in sequence. Specifically, the lower end of the first reclining mat 2 is hinged to the upper end of the second reclining mat 3 via a rotary joint 13, and the lower end of the second reclining mat 3 is hinged to the upper end of the third reclining mat 4 via a rotary joint 13. Thus, adjacent reclining mats can rotate relative to each other, forming an angle.
[0035] The third reclining mat 4 has two second rollers 7 at each of its bottom ends, which are arranged opposite to each other. When the lower end of the third reclining mat 4 is flipped backward, it can drive the two second rollers 7 to move behind the two first rollers 6, so that the two second rollers 7 and the two first rollers 6 form a four-wheel motion mechanism.
[0036] The outer frame 1 is also provided with a first locking member 11 and a second locking member 12. All three cushions slide downwards, allowing the first locking member 11 to lock the second cushion 3 and the second locking member 12 to lock the third cushion 4. Specifically, both the first locking member 11 and the second locking member 12 include two fixing sleeves, which are fixedly fitted onto the left connecting rod 17 and the right connecting rod 18 of the outer frame 1. These fixing sleeves prevent the sliding sleeves 10 from sliding. For example, when the second cushion 3 slides downwards, when the two sliding sleeves 10 at both ends of the sliding rod 20 of the second cushion 3 slide to the two fixing sleeves of the first locking member 11, the two fixing sleeves prevent the two sliding sleeves 10 from continuing to move downwards, thereby locking the second cushion 3. Similarly, the two fixing sleeves of the second locking member 12 prevent the two sliding sleeves 10 at both ends of the sliding rod 20 of the third cushion 4 from sliding downwards, thus locking the third cushion 4.
[0037] After the second reclining cushion 3 and the third reclining cushion 4 are locked, the lower end of the first reclining cushion 2 flips backward, the lower end of the second reclining cushion 3 flips forward, and the lower end of the third reclining cushion 4 flips backward. The second reclining cushion 3 flips to approximately a horizontal position to form a seat, the first reclining cushion 2 flips to form a backrest, and the two second rollers 7 and the two first rollers 6 form wheels, thus forming a trolley structure that the patient can sit on.
[0038] Considering that the ambulance stretcher of this utility model can be converted from a reclining to a sitting position and form a trolley structure, which is convenient to push and walk, the two top corners of the upper end of the outer frame 1 are rounded, and the top corners are provided with rubber sleeves 14, which can be easily pushed and walked by holding the rubber sleeves 14.
[0039] In some embodiments, to ensure better coordination between the second roller 7 and the first roller 6 in the sitting position, the lower end of the third reclining mat 4 is provided with a telescopic support rod 8. The second roller 7 is mounted on a wheel frame 9, and the wheel frame 9 is rotatably mounted on the lower end of the telescopic support rod 8. Thus, in the reclining position, the telescopic support rod 8 is shortened, allowing the second roller 7 to be neatly stored; while in the sitting position, the telescopic support rod 8 is extended, allowing the second roller 7 to cooperate with the first roller 6 for movement.
[0040] Furthermore, the recumbent-to-sitting emergency stretcher of this utility model also includes a fourth reclining pad 5. The lower end of the fourth reclining pad 5 is connected to the bottom of the outer frame 1 via a damping hinge, allowing the upper end of the fourth reclining pad 5 to be flipped forward to a predetermined angle. The fourth reclining pad 5 is arranged in the space below the non-sliding third reclining pad 4 within the outer frame 1, supported by the telescopic support rod 8. Under the action of the damping hinge, the upper end of the fourth reclining pad 5 flips forward to a predetermined angle, forming a footrest. The patient sits on the second reclining pad 3, and their feet can rest on the footrest.
[0041] like Figure 3 As shown, the recumbent stretcher of this utility model is in a supine position. The first lying pad 2, the second lying pad 3, the third lying pad 4 and the fourth lying pad 5 are all laid flat inside the outer frame 1 to form a supine position for the patient to lie flat. The patient can be transferred by lifting the stretcher.
[0042] like Figure 4 As shown, in the present invention, a recumbent and convertible ambulance stretcher is in a sitting position. The first reclining pad 2, the second reclining pad 3, and the third reclining pad 4 slide downwards. The second reclining pad 3 is locked by the first locking member 11, and the third reclining pad 4 is locked by the second locking member 12. The lower end of the first reclining pad 2 flips backward, the lower end of the second reclining pad 3 flips forward, and the lower end of the third reclining pad 4 flips backward. The second reclining pad 3 serves as a seat, and the first reclining pad 2 serves as a backrest. The two second rollers 7 and the two first rollers 6 form wheels, thus forming a trolley structure that allows patients to sit on it. By pushing the stretcher, patients can be transported.
