Description

Technical Field

[0001] This application relates to the field of medical assistive device technology, and more specifically, to a portable multifunctional stretcher for emergency use. Background Technology

[0002] A stretcher is a device used to transport injured people with limited mobility and is an important piece of equipment carried in emergency departments.

[0003] Currently, the main types of stretchers used in clinical practice are: 1. Lifting stretchers and wheeled stretchers; 2. Scoop stretchers; 3. Roll-up stretchers; 4. Basket stretchers; and 5. Folding stretchers. Lifting stretchers and wheeled stretchers have the advantage of being compatible with ambulances. After lifting and transporting the injured person onto the stretcher, the wheels can be used to move the patient to the ambulance, making loading, unloading, and transport convenient. Scoop stretchers can be disassembled and scooped under the injured person for lifting, minimizing movement during transport. Roll-up stretchers are lightweight, easy to carry, and suitable for use in confined spaces such as stairwells. Basket stretchers resemble cribs, preventing lateral movement after placing the injured person inside. Folding stretchers are compact and easy to carry.

[0004] In clinical practice and daily life, all four types of stretchers can be used for emergency transport of injured persons. However, the following problems exist: 1. Lifting stretchers and wheeled stretchers have complex structures, high costs, large sizes, and heavy weights, making them unsuitable for complex road conditions and narrow spaces; 2. Scoop stretchers are made of pure aluminum alloy, are heavy, have high costs, and are troublesome and time-consuming to disassemble; 3. Roll-up stretchers lack strength and have no fixed shape, making it easy for patients to move on them, potentially causing secondary injuries to fracture patients; 4. Basket stretchers are bulky, inconvenient to carry, and take up a lot of space, making them difficult to transport in ambulances; 5. Folding stretchers have complex structures, high costs, and can easily injure the operator during folding, and are difficult to disassemble and clean. Utility Model Content

[0005] To overcome the above-mentioned technical problems, this utility model provides a portable multi-functional stretcher for emergency use that is simple in structure, high in strength, easy to operate, low in cost, and can be disassembled and folded.

[0006] The technical solution for a portable multifunctional stretcher for emergency use provided in this application is as follows:

[0007] A portable multifunctional stretcher for emergency use includes two symmetrically arranged stretcher poles and a support cloth fixedly connected between the two stretcher poles. Each stretcher pole has a non-slip handle fitted at both ends. Each stretcher pole and non-slip handle has a through hole at its end, through which a safety rope is connected. Each stretcher pole has a ground-contact support rod fixedly connected to its bottom end. Each ground-contact support rod has a placement groove on its inner side. A transverse support rod is movably connected between the placement grooves of the two ground-contact support rods located at the same end. A limit fastener is rotatably fixed to the ground-contact support rod at the connection point at both ends of the transverse support rod for limiting and fixing the ends of the transverse support rod. The transverse support rod is a telescopically adjustable round rod. The depth and width of the inner wall of the placement groove are slightly larger than the diameter of the transverse support rod.

[0008] Furthermore, the bottom sidewall of the limiting fastener has a through groove with the same width as the placement groove, and the limiting fastener has a snap-fit ​​groove at the top of the through groove. The bottom of both ends of the horizontal support rod has a locking groove. The thickness of the horizontal support rod at the locking groove is the same as the width of the snap-fit ​​groove, so that the snap-fit ​​groove can engage with the locking groove when the limiting fastener rotates to limit the two ends of the horizontal support rod.

[0009] With the above technical solution, when the ground support rod is needed, rotate the stretcher rod to make the ground support rods on both sides vertical, insert both ends of the horizontal support rod into the placement groove, and rotate the limiting fastener so that the fastening groove can engage with the locking groove, which can effectively prevent the ground support rod from retracting and improve stability. When the ground support rod is not used, rotate the stretcher rod to make the bottom ends of the ground support rods on both sides face each other, rotate the limiting fastener so that its through groove is in the same position as the placement groove, and insert the horizontal support rod into the placement groove. Rotate the limiting fastener again to prevent the horizontal support rod from coming out.

[0010] Furthermore, the stretcher pole is a circular tube made of aluminum alloy, and the support cloth is a double-layer nylon cloth with snap fasteners inside the side interlayer.

[0011] The above technical solution involves wrapping the support fabric around the stretcher poles on both sides and securing it with snap fasteners to ensure a certain structural strength. Double-layered nylon fabric wraps around the two stretcher poles, restricting their outward extension and facilitating quick and easy disassembly of the support fabric for disinfection and cleaning (bloodstains, vomit, etc.), while also allowing the stretcher poles to rotate.

[0012] Furthermore, the two stretcher poles are connected by an adjustable shoulder strap through two through holes at the same end.

[0013] Through the above technical solution, the shoulder strap can be placed on the shoulder to reduce the burden on the hands by utilizing the shoulder's strength.

[0014] Furthermore, several auxiliary handles are fixedly connected to both sides of the support fabric.

[0015] The above technical solution makes it easier for bystanders to assist in lifting the stretcher from both sides.

[0016] Furthermore, several adjustable buckle straps are fixedly connected to both sides of the support fabric.

[0017] The adjustable buckle strap, as described above, is used to secure emergency patients, restrict their movement, and prevent them from falling.

[0018] Furthermore, the lateral support rod is an adjustable-length telescopic rod, and the telescopic part is equipped with fastening bolts to fix the telescopic support rod and limit its extension or retraction. In some technical solutions, the lateral support rod is a solid aluminum alloy rod with a non-adjustable length.

[0019] The above technical solution restricts the inward retraction of the stretcher poles and the movement of the ground contact support poles. The length of the transverse support poles can be adjusted and fixed, providing better fit and support when the bottom ends of the ground contact support poles are aligned. It also offers high compatibility with varying width requirements for the support fabric. Solid aluminum alloy transverse support poles, on the other hand, have a simpler structure, lower cost, are easier to operate, and offer higher strength.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] (1) By setting up ground support rods and transverse support rods, the transverse support rods can prevent the stretcher from shrinking inward due to the patient's weight, thereby avoiding excessive indentation of the nylon cloth in the stress-bearing part of the stretcher, which would cause the emergency patient to move and cause secondary injury to the emergency patient. On the other hand, it also avoids the situation where the stretcher poles are shortened, and the stretcher bearers' hands will shorten the distance, making it more difficult to lift.

[0022] (2) This application uses high-strength aluminum alloy for the main body, which is strong and lightweight. The stretcher load-bearing parts are made of double-layer nylon cloth, which is sturdy and durable, saves resources, has a simple structure, is easy to design for industrial manufacturing, and has a low manufacturing cost.

[0023] (3) This application is designed to be portable, can be disassembled and folded together, making it easy to carry and taking up little space. Attached Figure Description

[0035] Example 1:

[0036] The present application will be further described in detail below with reference to the accompanying drawings.

[0037] This application discloses a portable multifunctional stretcher for emergency use, including two symmetrically arranged stretcher poles 1 and a support cloth 2 fixedly connected between the two stretcher poles 1. Both ends of the stretcher poles 1 are fitted with rubber tubes as anti-slip handles 3. Both the stretcher poles 1 and the anti-slip handles 3 have through holes 4 at their ends, and a safety rope 5 is connected through the through holes 4. The safety rope 5 can also restrict the movement of the anti-slip handles 3. Both ends of the stretcher poles 1 are fixedly connected to ground support rods 6. The inner side of each ground support rod 6 is provided with a placement groove 7. A transverse support rod 8 made of aluminum alloy is movably connected between the placement grooves 7 of the two ground support rods 6 located at the same end. The ground support rod 6 is rotatably fixedly connected to the connection point at both ends of the transverse support rod 8 by a limiting fastener 9, which is used to limit and fix both ends of the transverse support rod 8. The transverse support rod 8 is a telescopically adjustable round rod. The inner wall depth and width of the placement groove 7 are slightly larger than the diameter of the transverse support rod 8.

[0038] Please see Figure 1-6 The bottom side wall of the limiting fastener 9 has a through groove 10 with the same width as the placement groove 7. The limiting fastener 9 has a horizontally opening fastening groove 11 at the top of the through groove 10. The bottom of both ends of the horizontal support rod 8 has a locking groove 12. The thickness of the horizontal support rod 8 at the locking groove 12 is the same as the width of the fastening groove 11, so that when the limiting fastener 9 rotates, the fastening groove 11 can engage with the locking groove 12 to limit the two ends of the horizontal support rod 8.

[0039] When the ground support rod 6 is needed, rotate the stretcher rod 1 to make the ground support rod 6 on both sides vertical, insert both ends of the transverse support rod 8 into the placement groove 7, rotate the limiting fastener 9, and the fastening groove 11 can be engaged with the locking groove 12, which can effectively prevent the ground support rod 6 from retracting and improve stability. When the ground support rod 6 is not used, rotate the stretcher rod 1 to make the bottom ends of the ground support rod 6 on both sides face each other, rotate the limiting fastener 9 so that its through groove 10 is in the same position as the placement groove 7, and the transverse support rod 8 can be inserted into the placement groove 7. Rotate the limiting fastener 9 again to prevent the transverse support rod 8 from coming out.

[0040] Preferably, the stretcher pole 1 is a hollow high-strength aluminum alloy tube approximately 2 meters long. A short aluminum alloy tube, approximately 10-20 cm long, is vertically welded to each end of the aluminum alloy tube at approximately 10-20 cm from both ends. This serves as a ground-contact support pole 6 and also prevents the support fabric 2 at the center of the aluminum alloy tube from sliding down. The support fabric 2 is a double-layered nylon fabric, with snap fasteners 21 (such as...) inside the interlayer on its sides. Figure 3 As shown), the support cloth 2 surrounds the stretcher rods 1 on both sides and is fixed by the snap fasteners 21 to ensure a certain structural strength. The double-layer nylon cloth wraps around the two stretcher rods 1, restricting the stretcher rods 1 from extending outward, and facilitating quick disassembly of the support cloth for disinfection and cleaning (bloodstains, vomit, etc.), while allowing the stretcher rods 1 to rotate.

[0041] Preferably, the two stretcher poles 1 are also connected by an adjustable shoulder strap 13 through two through holes 4 at the same end. The shoulder strap can be placed on the shoulders to reduce the load on the hands by utilizing the shoulders.

[0042] Preferably, several auxiliary handles 14 are fixedly connected to both sides of the support fabric 2 to facilitate assistance in lifting the stretcher by others on both sides.

[0043] Preferably, several adjustable buckle straps 15 are fixedly connected to both sides of the support cloth 2. The adjustable buckle straps are used to fix the emergency patient, restrict the movement of the emergency patient, and prevent the patient from falling.

[0044] Preferably, the transverse support rod 8 is an adjustable-length telescopic rod, and the telescopic part is provided with fastening bolts to fix the transverse support rod 8 after telescopic movement, limiting the extension or retraction of the transverse support rod 8. The length of the transverse support rod 8 can be adjusted and fixed, providing better fit and support when the bottom ends of the ground-contact support rods 6 are opposite each other, and it has high compatibility with the width requirements of the support cloth 2.

[0045] In some embodiments, the transverse support rod is a solid aluminum alloy rod with a non-adjustable length. Solid aluminum alloy transverse support rods have a simple structure, low cost, convenient operation, and higher strength.

[0046] The implementation principle of a portable multifunctional stretcher for emergency use in this application embodiment is as follows:

[0047] When using it, take the folded-up multi-functional portable stretcher out of your home or ambulance, etc. Figure 1 As shown, rotating the stretcher rod 1 brings the ground support rods 6 on both sides into a vertical position. The two ends of the transverse support rod 8 are then inserted into the placement grooves 7. Rotating the limiting fastener 9 allows the fastening groove 11 to engage with the locking groove 12, effectively preventing the stretcher rod 1 and ground support rod 6 from retracting due to the patient pressing down on the support fabric 2, thus improving stability. If the ground support rod 6 is not used, as... Figure 6 As shown, rotate stretcher rod 1 so that the bottom ends of the ground-contact support rods 6 on both sides are facing each other. Rotate the limiting fastener 9 so that its through groove 10 is in the same position as the placement groove 7. The transverse support rod 8 can be inserted into the placement groove 7. Rotate the limiting fastener 9 again to prevent the transverse support rod 8 from coming out. Place the stretcher next to the patient and move the patient onto the stretcher, or turn the patient to the side and put the stretcher under the patient. Then fasten the nylon adjustable buckle strap 15 to secure the patient and restrict the patient's movement. At this time, wrap the hand leash 5 around the wrist and use the adjustable shoulder strap 13 to put it on the shoulder, using the shoulder and hands to bear the force at the same time to reduce the pressure on the rescuer. When the stretcher is not in use, the transverse support rod 8 can be removed, and the stretcher can be folded or rolled up along the support cloth 2 and placed on the ambulance or in the warehouse, or the stretcher can be disassembled and cleaned.

[0048] In addition, this multi-functional stretcher can be used as a temporary bed for home or outdoor use. By rotating the stretcher rod 1, the ground support rods 6 on both sides are brought into a vertical position. The two ends of the horizontal support rod 8 are inserted into the placement groove 7. The limiting fastener 9 is rotated to limit the position. It can be placed on the ground for temporary use as a bed. When not in use, it can be disassembled and stored away, making it highly practical.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
